Abstract

PURPOSE:To reduce the frequency of generation of an erroneous report generated at the time of security start operation by performing the control to make a device in a state of security start after confirming whether the operation state of a sensor covering a security area is in a prescribed state suitable for starting the security. CONSTITUTION:When an operator depresses a start switch 101 to start the security, the operation state of the sensor of a prescribed sensor loop circuit 103 is checked to discriminate whether it is suitable for starting the security. The discrimination result is displayed on a display section 104. Therefore, when any door and window is left open, the state can be displayed to urge the operator to lock up doors and windows securely. After the display, a control section 108 executes the control to start the security. When discrimination result is 'No', no control signal to start the security is outputted from an output section even through a card is inserted into a card reader 106, and the transmission of an erroneous report to the monitoring center can be prevented without fail.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method and apparatus for a security system, and more particularly to improvement of security start control for setting a required security area in a security state in a mechanical security system.

[0002]

2. Description of the Related Art Conventionally, various sensors for detecting an intruder, for example, a sensor for detecting opening / closing of a window, a sensor for detecting opening / closing of a door, an infrared sensor for detecting infrared rays emitted from a human body, etc. are used in buildings, factories, etc. A machine that is installed in the required area for security and sends an alarm signal based on this abnormal signal to a specified monitoring center through a public telephone line or a dedicated line when these sensors generate an abnormal signal. Security systems are known. In this type of mechanical security system, the person in charge of management in the area, or the person who made the last exit, etc., locked all the doors and windows, and then, for example, the operation box placed near the door for the last exit. By performing a required operation on the control box, the security area assigned to the operation box can be immediately set to the security start state.

The operation necessary for starting the security is, for example, that the operator passes a magnetic card, which is assigned to the operator and in which necessary information for security is written, through the card reader of the operation box. The above-described operation is performed when the mechanical security system is in the security release state, so that the security area is immediately set to the security start state.

[0004]

Therefore, in the conventional security system of this type, when the operator inserts the card into the reader of the operation box to start the security,
Since the guarded area is immediately in the guarded state, if the window is forgotten to be closed in the guarded area, the output from the sensor due to this will be transmitted to the monitoring center as a false alarm. By the way, at the monitoring center, it is not possible to know whether the signal sent is the result of an erroneous operation by an appropriate operator, so in order to have the guard arrive at the site within a predetermined time after the alarm is issued. In the end, the transmission of the false information as described above results in unnecessary on-site dispatch of security guards, which is a major cause of significantly increasing the operating cost of the security system.

Therefore, an object of the present invention is to provide a control device for a security system that can reduce the occurrence of false alarms that occur when the security system starts a security operation, such as forgetting to close the window.

[0006]

SUMMARY OF THE INVENTION A feature of the present invention for solving the above-mentioned problem is that a security signal can be transmitted to a monitoring center based on the operation output of a sensor arranged for security. In a control method for a configured security system, an operating state of a sensor which is in charge of the predetermined security area in response to a first input operation for starting security of the predetermined security area is a predetermined state suitable for the start of security. And visually and / or audibly display the result of the determination, and then, in response to the second input operation, control for setting the predetermined security area in the security start state. There is a point to do it.

Another feature of the present invention is a controller for a security system configured to transmit a security signal to a surveillance center based on the actuation output of a sensor arranged for security. First operating means, and a determining means for determining whether or not the operating state of the sensor which is in charge of the predetermined security area in response to the operation of the first operating means is in a predetermined state suitable for starting security. It has a means for visually and / or audibly displaying the discrimination result of the discrimination means, and controls the security system so as to start the security of the predetermined security area after the determination result is displayed.

[0008]

According to the first operation, it is determined whether or not the operating state of the sensor in charge of the security area is in a predetermined state suitable for starting security, and whether it is in a predetermined state suitable for starting security. For example, characters are displayed by letters, pictures, symbols, sounds, or a combination thereof. After such a display is performed, control for starting the security of the predetermined security area is performed.

[0009]

1 is a block diagram showing an embodiment of a control device for a security system according to the present invention. The security system control device 100 does not show a security alarm signal based on the operation output of a sensor, such as a door sensor, a light sensor, a window glass sensor, or an intruder detection infrared sensor, which is provided for security. A start switch for controlling the start of security of a so-called mechanical security system, which is configured to be transmitted by wire or wirelessly to a monitoring center, and which acts as an input operation member for instructing the start of security. 101 is provided.

The start switch 101 is provided as a push button switch in this embodiment.
01 is connected to the determination unit 102.

The discriminating section 102 is a sensor loop circuit 103 composed of a sensor of the security system which is in charge of a required security area for controlling the start of security.
Information about the operating state of the sensor. Then, the determining unit 102 responds to the fact that the start switch 101 is pressed by the last person leaving the security area to be turned on, and the sensor loop circuit 103 is responsive.
It is determined whether or not the operating state of the sensor is suitable for starting security, that is, whether or not the sensor does not output the same as when an intruder exists due to forgetting to close the window door or the like. Although the embodiment of FIG. 1 shows the case where there is only one sensor loop circuit composed of the sensor which is in charge of the required security area to control the start of security, the start of security should be controlled. There may be more than one sensor loop circuit consisting of sensors in charge of the required security area. In such a case, the determination unit 102 can be configured to be connected to a plurality of sensor loop circuits and perform a required determination for all the connected sensor loop circuits.

The discrimination output indicating the discrimination result is displayed on the display unit 1.
04 and the output unit 105 in the control unit 108. In response to the determination output, the display unit 104 displays information regarding the suitability of the security start to the operator as visual information and / or auditory information such as voice. This display content is
For example, an abstract display such as simply forgetting to close a window may be used, but it is also possible to display it like any window or door. Even if the operator forgets to close the door, window, etc., the display information displayed by the display unit 104 allows the operator to immediately know the detailed contents.

In the illustrated embodiment, the control unit 108 has a card reader 106 and a collating unit 107 in addition to the output unit 105.
Is equipped with. The card reader 106 is an input device for taking in the recorded data of a magnetic card of a predetermined standard in which the unique information of each person who is allowed to enter and leave the security area is recorded. Is provided as. For example, when the last person leaves his or her card on the card reader 106, the contents recorded on the card are checked by the collation unit 10.
7 to check whether or not the card is a pre-registered valid card. This match is
This is performed using the security data given in advance to the matching unit 107, and if the card is a valid card, the matching unit 107 sends matching information to the output unit 105.

The output unit 105 receives from the discriminating unit 102 information that the operating state of the sensor in the sensor loop circuit 103 is suitable for the start of security, and also receives matching information from the collating unit 107. Only in this case, the output unit 105 outputs a security start control signal for bringing the security system into the security state and sends it to a security system (not shown), whereby security by the security system is started.

According to this configuration, when the operator presses the start switch 101 to start security, the operating state of the sensor of the predetermined sensor loop circuit 103 is checked, and it is determined whether the operation is suitable for the start of security. Is determined, and the result of this determination is displayed on the display unit 104. Therefore,
These can be displayed when the user forgets to close the door, window, etc., or when an animal has entered the room, and the operator can be prompted to confirm the door lock. Then, after this display is performed, the control unit 108 executes control for starting security.

Further, when it is determined that the operating state of the sensor is not suitable for starting security, even if a card is inserted in the card reader 106, a control signal for starting security of the security system is generated. Since there is no output from the output unit 105, it is possible to reliably prevent an erroneous report from being transmitted to the monitoring center at the same time as the security start operation due to incompleteness such as door locking.

In the embodiment shown in FIG. 1, a method has been described in which the start switch 101 is first operated and then the card is inserted into the card reader 106, but a configuration in which these are reversed is also possible. That is, an input operation unit including a card reader 106 and a collation unit 107 is used as the first input operation unit, the output thereof is sent to the determination unit 102, and the start switch 101 is used as the second input operation unit, and the start switch 101 is used. May be connected to one input of the output unit 105.

In this configuration, the operator first puts his or her card on the card reader 106 and the recorded contents are collated. As a result of the collation, the coincidence output is input to the discriminating unit 102 to discriminate the operating state of the sensor, and only when it is discriminated that the result is suitable for the start of security, the operation of the start switch 101 is responded. Then, the security system is controlled so as to be in the security starting state. Further, in any case, after the discrimination result is displayed, the security start state can be set in response to the operation of the second input means at any time.

Next, another more specific embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic view showing a security system to which another embodiment of the security system control device according to the present invention is applied. In this embodiment, a door sensor S1 for detecting the open / closed state of the door 1a and a window sensor S2 for detecting the open / closed state of the window 1b are provided in the security area 1.
Is provided, and a sensor loop 11 including these sensors S1 and S2 is formed.

This sensor loop 11 is connected to a transmitter 3 which is connected to an operation box 2 mounted on the outer wall near the door 1a. Intrusion information into the security area 1, for example, when one of the sensors S1 and S2 is activated and the sensor loop 11 is turned off, the transmitter 3 detects this and an alarm output is sent from the transmitter 3 to the monitoring center 4.
Sent to. Moreover, the monitoring center 4 can control the transmitter 3 and the transmitter 3 can control the operation box 2 as needed. The transmitter 3 and the monitoring center 4 are connected by the subscriber telephone line 5, but in addition to this, it is also possible to connect both by a dedicated line.

FIG. 3 is a view showing a panel of the operation box 2 of FIG. In FIG. 3, reference numeral 21 denotes a mounting frame, a panel portion 23 of the main body is screwed to the mounting frame 21, and a bezel 22 is fitted around the panel portion 23. The panel unit 23 is provided with a security start switch 24 that is first pushed when starting security, a security release switch 25 that is first pressed when canceling security, and a clear switch 26 that is pressed when stopping an operation in progress. There is. Also, 2
Reference numeral 7 denotes a card insertion slot into which a card in which the identification information of the operator is recorded is inserted.
7a (not shown in FIG. 3 but shown in FIG. 4) is provided.

Reference numeral 28 is a display device (for example, LCD) for displaying each operation instruction, the operating state of the system, etc., and below the display device, there are function switches F1, F2, F for operation.
3 is provided. Reference numeral 29 denotes a speaker, which is provided as a display device for displaying by voice, for example, by voice when there is no next operation even after a lapse of a predetermined time. Further, reference numeral 30 is a lamp which is turned on when the security is started and turned off when the security is released.

In the operation box 2, there is provided a control device for controlling the security system in response to signals from the above-mentioned operation members. In this embodiment, the controller is configured as a microcomputer system, as will be described in detail below.

FIG. 4 is a block circuit diagram showing details of the control unit in the operation box 2. The operation box control unit 31 is composed of a microcomputer, and has a CPU 40.
1, a ROM 402 for storing programs, constants and the like, a RAM 403 for storing temporary data, a communication control unit 404 for controlling communication with the transmitter 3, an input / output interface 405, and the like, which are internal buses 406. Connected by. This input / output interface 4
05 includes a security start switch 24 and a security release switch 2
5, a clear switch 26, a card reader 27a, a display device 28, function switches F1, F2, F3, a lamp 30 and the like are connected. A control program for controlling the security system is stored in the ROM 402, and this control program is executed by the CPU 401 to achieve a required control function. The speaker 29 for voice display is connected to the voice synthesizer 32 that receives the control signal via the internal bus 406.

The control according to the control program will be described below with reference to FIGS. FIG. 5 is a main routine, which starts after the power of the operation box 2 is turned on. Here, steps 501 and 502 are executed only once after the main routine is started, and thereafter, only step 503 is continuously executed.

In step 501, the RAM 403 and the like are initialized, and in step 502, among the setting data downloaded from the monitoring center 4 to the transmitter 3,
RAM403 of the operation box control unit 31 necessary data
To load. The setting data includes, for example, a card registration number, a personal identification number, screen display message data, and sensor character data (for example, doors, windows, etc.), which are generally centrally maintained in the monitoring center 4. Then the flow proceeds to idle routine step 503.

FIG. 6 shows the idle routine step 5 of FIG.
It is a detailed flowchart of 03. In step 601, the state flag F in the RAM 403 is read out, and the current state is the security release state (F = “0”) or the security state (F =
"1"). As a result, if the security is released, the flow proceeds to step 602 to determine whether the security start switch 24 is on, and execute the steps 603 to 606 only when the security start switch 24 is on. On the contrary, if it is in the guarded state, the flow is step 6
In step 07, it is determined whether or not the security release switch 25 is on. Only when the security release switch 25 is on, step 6
08 is executed. If neither the security start switch 24 nor the security release switch 25 is turned on, step 60
Return to 1.

If the operator mistakenly inserts the card into the card insertion slot before turning on the security start switch 24 and the security release switch 25, the display device 2
It is also possible to display the message “Please press the switch first” on 8 to alert the operator. Further, in the security release state (F = “0”), if the operator mistakenly turns on the security release switch 25 again,
It is also possible to display "Under security" on the display device 28 to alert the operator. Further, when the operator mistakenly turns on the security switch 24 again in the security state (F = “1”), the display device 28 displays “Security is in progress” to warn the operator. It can also be evoked.

Next, steps 603 to 606 will be described. At step 603, a loop check is performed. That is, the sensors S1 and S managed by the operation box 2
At least 1 of 2 (of course, there may be 3 or more)
It is determined whether one is in the abnormal loop state due to forgetting to close the door, window, etc. As a result, if the loop is in the normal state, the process proceeds to the security start routine of step 604. Step 6
04 will be described later. On the contrary, if the loop is in an abnormal state, the process proceeds to steps 605 and 606. In step 605, “Loop is abnormal.” Is displayed on the display device 28, and this display state is maintained in step 606 for a certain period of time, for example, 10 seconds, whereby the operator forgets to close the door, window, etc. Please note that there is. Then, the process returns to step 601. Therefore, in the case of a loop abnormality, the procedure does not proceed directly to the security start step 604, and after the operator closes the door, the window, etc. and the loop becomes normal, the security start switch 24 is turned on again to start the flow. The process will proceed to start step 604.

On the other hand, in step 607, when the security release switch 25 is turned on, step 603
The security check step 608 is directly executed without performing the loop check. The security release step 608 will be described later.

7 and 8 show the security starting step 60 of FIG.
4 is a detailed flowchart of 4. In step 701, the display device 28 displays "a picture that means insert a card" to instruct the operator to insert a card. As a result,
Only when the operator inserts the card, the process proceeds to step 703 through step 702. Although not shown, step 6 in FIG. 6 is performed when the card is not inserted for a certain period of time.
It is configured to return to 01.

In step 703, it is determined whether or not the card is normal, that is, whether or not the card number has been registered.
As a result, if the card is already registered, step 704
If the card is not registered, the process proceeds to step 705. In step 705, "Please check the card" is displayed on the display device 28 to indicate the error of the card to the operator, and the flow returns to step 601 in FIG.

At step 704, it is judged whether or not the personal identification number is set. As a result, when the personal identification number is set, the flow of steps 706 to 710 is executed, and when the personal identification number is not set, the process directly proceeds to step 711.

In step 706, "Enter your PIN" is displayed on the display device 28, and the operator is instructed to enter the PIN. next,
In step 707, the operator waits for input of the personal identification number by using, for example, the three function switches F1, F2, F3, and after the personal identification number is input, the process proceeds to step 708. Note that when the personal identification number is not input even after a certain period of time, the process returns to step 601 of FIG. 6 by a step not shown.

In step 708, it is determined whether or not the input personal identification number is normal, that is, whether the personal identification number registered for the card and the personal identification number just input match. As a result, when the entered personal identification number matches the registered personal identification number, step 71
If it does not match, the process proceeds to step 709. In step 709, the number of times of input is counted, and the input of the personal identification number is permitted up to five times. If the number of inputs is less than 5, the display device 28 displays "The password is wrong" in step 717, and the process returns to step 707. On the other hand, when the personal identification number is input five times, lockout abnormality processing is performed in step 710, the processing is prohibited for, for example, 1 minute, and then the processing returns to step 601 in FIG.

In step 711, it is determined whether or not the card has been removed. As a result, when the card has not been removed, in step 716, "a picture meaning that the card should be removed" is displayed on the display device 28, and the operator is informed that he has forgotten to remove the card and returns to step 711. . When the card is removed, the process proceeds to step 712.

In step 712, the transmitter 3 is requested to start security, and in step 713, the transmitter 3 waits for confirmation of security start. When the transmitter 3 starts security, the transmitter 3 notifies the monitoring center 4 together with the operation box 2 to that effect. Upon receiving a security start notification from the transmitter 3, the flow proceeds to steps 714 and 715 via step 713. That is, in step 714, the state flag F is set to "1" indicating the security state, and in step 715, the lamp 30 is turned on to indicate that the system is in the security state, whereby the security system enters the security state.
Then, the process returns to step 601 in FIG.

9 and 10 show the security release routine 6 of FIG.
08 is a detailed flowchart of Step 08,
To 915 substantially correspond to steps 701 to 715 of FIG.

That is, in step 901, the display device 28 displays "a picture that means insert a card" to instruct the operator to insert a card. As a result,
Only when the operator inserts the card, the process proceeds to step 903 through step 902. Although not shown, step 6 in FIG. 6 is performed when the card is not inserted for a certain period of time.
Returning to 01 is the same as in the case of FIG. 7.

In step 903, it is determined whether or not the card is normal, that is, whether or not the card number has been registered.
As a result, if the card is already registered, step 904
If the card is not registered, the process proceeds to step 905. In step 905, "Please check the card" is displayed on the display device 28 to indicate the error of the card to the operator, and the flow returns to step 601 in FIG.

At step 904, it is judged whether or not the personal identification number is set. As a result, when the personal identification number is set, the flow of steps 906 to 910 is executed, and when the personal identification number is not set, the process directly proceeds to step 911.

In step 906, "Please input the personal identification number" is displayed on the display device 28, and the operator is instructed to input the personal identification number. next,
In step 907, the operator waits for input of the personal identification number by using, for example, the three function switches F1, F2, F3, and after the personal identification number is input, the process proceeds to step 908. Note that, when the personal identification number has not been input even after a certain period of time, the process returns to step 601 of FIG. 6 by a step not shown, as in the case of FIG.

In step 908, it is determined whether or not the input personal identification number is normal, that is, whether the personal identification number registered for the card matches the personal identification number just input. As a result, when the entered personal identification number matches the registered personal identification number, step 91
If it does not match, the process proceeds to step 909. In step 909, the number of times of input is counted, and the input of the personal identification number is permitted up to five times. If the number of times of input is less than 5, the display device 28 displays “The password is wrong” in step 917 and the process returns to step 907. On the other hand, when the personal identification number is input five times, the lockout abnormality process is performed in step 910, the process is prohibited, for example, for 1 minute, and then the process returns to step 601 in FIG.

In step 911, it is determined whether the card has been removed. As a result, when the card has not been removed, in step 916, "a picture meaning that the card should be removed" is displayed on the display device 28, the operator is informed that the card has not been removed, and the process returns to step 911. . When the card is removed, the process proceeds to step 912.

At step 912, the transmitter 3 is requested to release the security, and at step 913, the transmitter 3 waits for confirmation of the security release. When the transmitter 3 releases the security, the transmitter 3 notifies the monitoring center 4 together with the operation box 2 to that effect. Upon receiving the security release notification from the transmitter 3, the flow proceeds to steps 914 and 915 via step 913. That is, in step 914, the state flag F is set to “0” indicating the security release state,
In step 915, the lamp 30 is turned off, which brings the security system into the security release state. And FIG.
Return to step 601 of.

In the above description, the display to the operator is visual by the display device (LCD) 28. However, in addition to or instead of this, the speaker 29 is used.
The audio display by can be used.

[0047]

As described above, according to the present invention,
In response to a predetermined input operation, it is determined whether or not the operating state of the sensor in charge of the predetermined security area is suitable for the start of security, and the determination result is visually and / or audibly displayed. Since it is configured to perform the control to put the predetermined guard area into the guard start state, if the user forgets to close the windows, doors, etc. when trying to put the guard start state by the predetermined input operation, the guard starts. This can be surely informed to the operator before the control of (1) is performed, whereby the security start state can be achieved after the forgetting to close the windows, doors, etc. Therefore, it is possible to significantly reduce the occurrence of false alarms due to inadequacy such as door locking due to carelessness at the start of security, and it can be expected to significantly reduce the monitoring cost of the security system.
