[0002]

2. Description of the Related Art Various sensors for detecting an intruder, such as 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, are required in buildings, factories, etc. There is known a mechanical security system which is arranged in a security target area and sends an alarm to a predetermined monitoring center through a public telephone line or a dedicated line when these sensors generate an abnormal signal. This type of mechanical security system usually has a function of self-checking whether or not each unit of the device is operating normally. For example, the person in charge of the area or the last person leaving the room may lock the door or window, and then perform the required operation on the operation box located near the door for the last person leaving the operation. The security area assigned to the box can be set to the security start state, but if you forget to lock the windows, doors, etc., the alarm lamp provided on the operation box will be turned on and the operator will be informed that something is wrong. A configuration for notifying is known.

[0003]

However, even if the alarm lamp of the operation box is turned on, it is not possible to know where the abnormality is, even if it is known that there is an abnormality in the loop. I had to re-enter the room and check all locks. As described above, in the case of the security device used in the conventional mechanical security system of this kind, even if it is detected that the device is abnormal or defective, the content of the security device can be properly confirmed to the operator. However, the operator has a problem that he has to check all the parts again by his own judgment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a mechanical security system constructed by using a security device according to the present invention. This mechanical security system 1 guards an office 2, which is a required facility to be guarded, so that a security device generally designated by the reference numeral 10 is constructed according to the present invention, and a security device from the security device 10. A monitoring center X for receiving a warning signal is provided, and the security device 10 and the monitoring center X are connected by a public telephone line Y.

In the embodiment of FIG. 1, for simplification of description, only one of the many security devices monitored by the monitoring center X is shown, but in reality, the monitoring center X is The public telephone line Y can be connected to a large number of other security devices (not shown), and the monitoring center X is configured to monitor signals from a large number of security devices. However, there is no problem even if the configuration is such that one surveillance center monitors one security device. Further, the monitoring center X and each security device may be connected by a dedicated line or other appropriate communication means.

The security device 10 comprises a transmitter 11 configured as a microcomputer system having a communication control function, a sensor loop 12 and an operation box 13 connected to the transmitter 11.

The sensor loop 12 includes a door sensor 14 for detecting the open / closed state of the door 3 and a window sensor 15 for detecting the open / closed state of the window 4. The sensor loop 12 is opened when the window 4 or the door 3 is opened. This is a known configuration in which 12 is in an open state. The sensor loop 12 is connected to the input / output interface circuit (I / O) 16 of the transmitter 11.

In addition to the I / O 16, the transmitter 11 includes a central processing unit (CPU) 17, a read-only memory (ROM) 18 for storing programs, constants, etc., and a random access memory for storing temporary data. (RAM) 1
9 and a communication control unit 20 for controlling communication with the monitoring center X, which are mutually connected by an internal bus 21.

The operation box 13 is attached to an appropriate place near the door 3 which is the final exit and convenient for operation, and a card reader 22 for reading the contents of an ID card of a predetermined format, The display unit 23 is a flat display device having a flat liquid crystal display panel with a backlight, and the details of the panel surface are as shown in FIG.

Referring to FIG. 2, reference numeral 26 denotes a mounting frame. A panel portion 27 of the main body is screwed to the mounting frame 26, and a bezel 28 is fitted around the panel portion 27. The panel unit 27 is provided with a security start switch 28 which is first pushed when starting security, a security release switch 29 which is first pressed when releasing security, and a clear switch 30 which is pressed when the operation being executed is stopped. There is. Further, reference numeral 31 is a card insertion port into which an ID card in which the identification information of the operator is recorded is inserted, and the card reader 22 is provided therein.

Reference numeral 23 is a display unit for displaying each operation instruction, the operating state of the system and the like. In this embodiment, a flat liquid crystal display device is used, but it is any other suitable flat display device. Good. Below that, operation function switches F1, F2, and F3 are provided. Reference numeral 32 denotes a speaker, which is used for displaying a voice so that, for example, if there is no next operation even after 5 seconds, a voice notification is given. Further, 33 is a lamp which is turned on when the security is started and turned off when the security is released.

In the operation box 13, there is provided a control device for controlling the security system in response to signals from the above-mentioned operation members. In the present embodiment, this control device is configured as a microcomputer system as described below.

FIG. 3 is a block circuit diagram showing details of the control unit in the operation box 13. The control unit 40 is composed of a microcomputer, and includes a CPU 41, a ROM 42 for recording programs, constants, etc., a RAM 43 for storing temporary data, a communication control unit 44 for controlling communication with the transmitter 11, and an input / output interface 45. , And these are connected by an internal bus 46. The input / output interface 45 includes a security start switch 28, a security release switch 29, and a clear switch 3.
0, the card reader 22, the display unit 23, the function switches F1, F2, F3, the lamp 33, etc. are connected as shown. A control program for controlling the security system is stored in the ROM 42, and this control program is executed by the CPU 41 to achieve a required control function. Speaker 32 for audio display
Is connected to the voice synthesizer 34 that receives the control signal via the internal bus 46.

The ROM 42 further stores a large amount of various character information (including pictographic information) data to be displayed by the display unit 23, which will be described later, and is required when the display of the character information is requested. Character information data is sent to the display unit 23, and characters (pictograms) are displayed on the display unit 23 in an appropriate form. Therefore, the character information data stored in the ROM 42 is
For example, "I am on guard.""Loop XX is abnormal."
Each of the required character information such as is a data string for displaying a character, and a set of required data strings for displaying a character is sent to the display unit 23 in response to a display request to perform character display. Has become. However, the configuration for displaying characters is not limited to the one configuration example described above, and it goes without saying that another appropriate configuration may be used.

The control according to the control program will be described below with reference to FIGS. 4 to 9.

FIG. 4 is a main routine, which is started after the operation box 13 is powered 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 43 and the like are initialized, and in step 502, of the setting data downloaded from the monitoring center X to the transmitter 11,
Required data is loaded into the RAM 43 of the operation box control unit 40. 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.).
It is centrally maintained at the monitoring center X. next,
The flow proceeds to idle routine step 503.

FIG. 5 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 43 is read, 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, where it is determined whether the security start switch 28 is on, and the steps 603 to 606 are executed only when the security start switch 28 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 29 is ON, and only when the security release switch 29 is ON, step 6
08 is executed. If neither the security start switch 28 nor the security release switch 29 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 28 and the security release switch 29, the display unit 23
It is also possible to display the text "Please press the switch first" on the screen to alert the operator. Also,
When the operator mistakenly turns on the security release switch 29 again in the security release state (F = “0”), the display unit 23 displays the message “Security release is in progress.” You can also call attention to. Furthermore, when the operator mistakenly turns on the security switch 28 again in the security state (F = “1”), the display unit 23 displays the message “Security is in progress” to the operator. You can also call attention.

It has already been explained that the display of the characters "Unlocking" and "Security is in progress" can be realized by reading the character information data string corresponding to these from the ROM 42 and sending it to the display unit 23. As I did. The same applies to the following description.

Next, steps 603 to 606 will be described. At step 603, a loop check is performed. That is, the sensor 14 managed by the operation box 13,
It is determined whether or not at least one of 15 (of course, three or more) is in a loop abnormal state due to forgetting to close the door, window, or the like. As a result, if the sensor loop 12 is in the normal state, the process proceeds to the security start routine of step 604. Step 604 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, the loop in the abnormal state is specified, and the character information data string for character display corresponding to the result is read from the ROM 42 and sent to the display unit 23. As a result, the characters "Loop 12 is abnormal." Are displayed on the display unit 23, and this display state is maintained for a certain period of time, for example, 10 seconds in step 606, whereby the operator can close the door, window, etc. Remember that you are forgetful. Then, the process returns to step 601. Therefore, in the case of a loop abnormality, the security start step 604
If the operator closes the door, window, etc. and the loop becomes normal, the guard start switch 28 is turned on again to start the flow, and the flow proceeds to the guard start step 604.

On the other hand, when the security release switch 29 is turned on in step 607, step 603 is executed.
The security check step 608 is directly executed without performing the loop check. The security release step 608 will be described later.

6 and 7 show the security starting step 60 of FIG.
4 is a detailed flowchart of 4. In step 701, the display unit 23 displays a pictogram that is "a picture that means insert a card" to instruct the operator to insert a card. As a result, the process proceeds to step 703 via step 702 only when the operator inserts the card. Although not shown in the figure, when the card is not inserted for a certain period of time, the process returns to step 601 of FIG.

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, the character string "Please check the card." Is displayed on the display unit 23 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, the character string "Please input the personal identification number." Is displayed on the display unit 23, and the operator is instructed to input the personal identification number. Next, step 70.
In step 7, the operator waits for the personal identification number to be input using, for example, the three function switches F1, F2 and F3, and the personal identification number must be input before proceeding 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. 5 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. When the number of times of input is less than 5, the character "The password is wrong" is displayed on the display unit 23 in step 717, and the process returns to step 707. On the other hand, when the personal identification number is input five times, the lockout abnormality process is performed in step 710, the process is prohibited, for example, for one minute, and then the process 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 pictogram "a picture meaning that the card should be removed" is displayed on the display unit 23, and the operator is informed that he / she has forgotten to remove the card. 71
Return to 1. 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 11 waits for confirmation of security start. In addition, the transmitter 11
When the security guard starts, the transmitter 11 notifies the monitoring center X together with the operation box 13 to that effect. Upon receiving a security start notification from the transmitter 11, the flow advances to steps 714 and 715 via step 713. In other words, in step 714, the state flag F is set to "1" indicating the security state, and in step 715, the lamp 33 is turned on to indicate that security is being performed, whereby the security system enters the security state. Then, the process returns to step 601 in FIG.

8 and 9 show the security release routine 60 of FIG.
8 is a detailed flowchart of Step 8, and Steps 901 to 915 substantially correspond to Steps 701 to 715 of FIG.

That is, in step 901, the display unit 2
At 3, a pictogram that is "a picture that means insert a card" is displayed to instruct the operator to insert the card. As a result, step 9 is performed only when the operator inserts the card.
It progresses to step 903 via 02. Although not shown, returning to step 601 in FIG. 5 when the card is not inserted for a certain period of time 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, the character string "Please check the card" is displayed on the display unit 23 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, the characters "Please enter your PIN" are displayed on the display unit 23, and the operator is instructed to enter the PIN. Next, Step 90
At 7, the operation waits for the operator to input 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 is not entered even after a certain period of time, it is possible to return to step 601 of FIG. 5 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 and the personal identification number just input match. 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. When the number of times of input is less than 5, the character "The password is wrong" is displayed on the display unit 23 in step 917, and the process returns to step 907. On the other hand, when the number of inputting the personal identification number reaches 5, the lockout abnormality process is performed in step 910, the process is prohibited for, for example, 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 pictogram that is "a picture meaning that the card should be removed" is displayed on the display unit 23, and the operator is informed that he has forgotten to remove the card. 91
Return to 1. When the card is removed, the process proceeds to step 912.

In step 912, the transmitter 11 is requested to cancel the security, and in step 913, the transmitter 11 waits for confirmation of the security cancellation. In addition, transmitter 1
When the security guard 1 is released by the security guard 1, the transmitter 11 operates in the operation box 13
At the same time, it notifies the monitoring center X of that fact. Upon receiving the security release notification from the transmitter 11, 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, and the lamp 30 is turned off in step 915, whereby the security system enters the security release state.
Then, the process returns to step 601 in FIG.

In the above-described embodiment, an example of displaying the character information (including pictographic information) on the display unit 23 as the information necessary for the operation of starting and releasing the security is shown. The present invention is not limited to the configuration shown in the example, and the check result of each unit obtained by executing the self-diagnosis program may be displayed on the display unit 23 by text information, or a message from the monitoring center may be displayed. It may be configured to display as character information in the unit 23. That is, what is displayed on the display unit 23 provided in the operation box may be at least information related to the security system, and the use of the display unit is not limited to a specific use.
