BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code information discriminating apparatus.

[0002]

2. Description of the Related Art For example, in order to control the entrance and exit of a person to and from a predetermined area in a security system or the like, a ten-key device is provided at the entrance of the area, and a person who tries to enter the area is given a specific number. By inputting the personal identification number from the ten-key device, it is collated whether the personal identification number input from the ten-key device is a pre-registered number, and whether or not the collation result input personal identification number is registered, That is,
A configuration is known in which the suitability of the input code information is determined and only when the input personal identification number is valid, the entrance door is unlocked. Thus, a system in which a personal identification number or the like is input from a predetermined input device, the suitability of the input code information is determined, and a security device or other device is controlled according to the result is widely adopted in various fields. ing. Conventionally, when attempting to perform such a PIN code determination, for example, a PIN number that is a combination of about four digits is determined in advance as a PIN code, and this PIN number is input using a ten-key device. It is common.

[0003]

Therefore, in this type of device for determining the suitability of input code information, an element to be used selected from numbers, letters, symbols, etc., for example, numbers from 0 to 9 is used. , Input keys must be provided in advance, and the number of input keys must be at least 1.
It required about 0 pieces. However, if 10 or more input keys are provided, a space for this is required, which causes a problem that the device becomes large and the cost becomes high.

Therefore, an object of the present invention is to provide a code information discriminating apparatus which can solve the above-mentioned problems in the prior art and which requires a small number of operation members for data input.

[0005]

A feature of the present invention for solving the above-mentioned problems is that a code having a predetermined number of digits is formed by arbitrarily arranging predetermined elements selected from numbers, characters, symbols and the like. In a code information determining device for determining the suitability of information, a plurality of input operation members of a number smaller than the number of the predetermined elements used to input the required code information,
A display member that displays the correspondence between each of these input operation members and the type of the predetermined element, and output means that outputs collation data that responds to the operation of the input operation member and that follows the operation order of the input operation member. And a means for providing reference data for determining the suitability of the collated data, and a determining means for responding to the reference data and the collated data to determine the suitability of the collated data. .

[0006]

When the required code information is input by operating each input operation member according to the display by the display member, the output means outputs the collated data corresponding to the required code information. The suitability of the collated data is determined according to the reference data.

[0007]

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 code information discriminating apparatus according to the present invention. The code information discriminating apparatus 100 discriminates whether or not the input code information is proper in light of the data registered in advance, that is, the propriety thereof, and the input code information is discriminated as being proper. Entrance door 10 only if
The door control device 103 is provided with a security control signal X for unlocking the electric lock 102 provided in FIG.

In the illustrated embodiment, the secret code required to unlock the door 101 is defined as a four-digit number which is an arbitrary combination of numbers 0 to 9. The personal identification number defined in this way is individually determined for each of N authorized persons who need to pass through the door 101, and N personal identification numbers Y1
Through Yn can be registered in advance.

The code information discriminating apparatus 100 has three push button switches 104, 105 and 106 as input operation members for inputting a personal identification number, and liquid crystal is provided in the vicinity of these push button switches 104 to 106. Display 10
7 is provided. In response to the display control signal DP from the display control device 108, the liquid crystal display 107 is one of the numbers 0 to 9 to which the pushbutton switches 104, 105, 106 are assigned, that is, an input operation member. It is a display member for displaying the correspondence relationship between each of the push button switches 104, 105 and 106 and the numbers 0 to 9. In the illustrated embodiment, the pushbutton switch 104
Is assigned to input the numbers 1, 4, and 7,
It is displayed that the push button switch 105 is assigned for inputting the numbers 2, 5, 8, 0, and the push button switch 106 is assigned for inputting the numbers 3, 6, 9.

This assignment can be arbitrarily changed by externally giving display assignment data PA to the display control device 108. Which number is assigned to each push button switch 104, 105, 106. Display data AD indicating whether or not the display control device 1
It can be taken out from 08.

When the push button switches 104 to 106 are operated in accordance with the display on the liquid crystal display 107 to input a required personal identification number, the push button switches 104, 105, 10
The data output unit 109 to which 6 is connected outputs the input information data CA determined according to the operation order of the push button switches 104, 105, 106. That is, when the push button switches are pressed in the order of 105 → 104 → 104 → 105 to input the personal identification number (2748), a code peculiar to this operation sequence of the push button switches is output as the input information data CA. The input information data CA is input to the determination unit 110 for the suitability check for determining whether or not the content is the content registered in advance.

Reference numeral 111 denotes a memory in which the above-mentioned N personal identification numbers Y1 to Yn are stored in advance from the outside, and the contents of the memory 111 are the conversion unit to which the display data AD is input. Has been sent to 112.
In the conversion unit 112, the numbers 0 to 9 are arbitrarily used.
Each of the personal identification numbers Y1 to Yn consisting of digits is displayed on the push button switch 10 according to the contents displayed on the display device 107 at that time.
Display the order when 4, 105 and 106 are operated 2
Each data is converted into the following data, and the data thus obtained is stored as the reference data ST, and the reference data ST is given from the conversion unit 112 to the determination unit 110.

The discriminating section 110 compares the input information data CA with the reference data ST and discriminates whether or not the same data as the input information data CA is present in the reference data ST, that is, the adequacy of the input information data CA. It

If the same data as the input information data CA is present in the reference data ST, it is determined that the content of the input information data CA at that time, that is, the personal identification number input at that time is appropriate, and the discriminating unit 110 determines that The security control signal X is output, and the electric lock 102 provided on the door 101 is unlocked.

According to this structure, the liquid crystal display device 10 is provided with a four-digit personal identification number which is an arbitrary combination of numbers from 0 to 9.
According to the display of 7, only 3 pushbutton switches 10
4, 105, 106 can be input. Further, since there are only three operation members for inputting, even if the third person sees the movement of the hand when the operator operates the push button switch, the content of the personal identification number, that is, the four-digit It also has the advantage that the permutation contents of numbers are not analyzed.

Further, in this embodiment, since the numbers assigned to the respective push button switches are displayed on the liquid crystal display device 107, when the assignment is changed, the display is promptly changed accordingly. Therefore, for example, by changing the allocation every day, it is possible to more surely prevent the outsider from inputting appropriate data.

Of course, instead of the liquid crystal display device 107, what is printed on paper or the like may be attached to the panel surface. In this case, for example, the fixed data corresponding to the display data AD may be stored in an appropriate memory and given to the conversion unit 112.
Further, in this case, the reference data corresponding to Y1 to Yn is calculated in advance, the calculation result is stored in an appropriate memory, and the stored reference data is given to the determination unit 110. can do.

In the above embodiment, the push button switch 10
4, 105 and 106 are used only for inputting the personal identification code, these pushbutton switches 104, 105 and 10
6 may be configured to be used for other purposes, and the liquid crystal display device 107 may be configured to be used for other displays in the same manner.

Next, another embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic diagram showing a security system using the code information discriminating apparatus according to the present invention. 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 arranged in the security area 1, and these sensors S1,
A sensor loop 11 including 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, and the like, and below the display device, operation function switches F1, F2, F.
3 is provided. As will be described later in detail, these function switches F1, F2, F3 are used as input operation means for inputting a personal identification code unique to the operator, and in that case, the display device 28 causes each function switch F1 to operate. , F2, and F3 are assigned numbers 0 to 9 in FIG.
The display is performed as shown in FIG. Reference numeral 29 denotes a speaker, which is used for displaying by voice, for example, by notifying by voice when there is no next operation even after 5 seconds. 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 "Please press the switch first" on 8 to call the operator's attention. If the operator mistakenly turns on the security release switch 25 again in the security release state (F = “0”), the display device 28
In addition, it is possible to display the message "Security is being released" to alert the operator. Furthermore, security status (F = "1")
In the above, if the operator mistakenly turns on the security switch 24 again, the display device 28 can display “Security is in progress” to alert the operator.

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 displayed in step 606.
For a certain period of time, for example, for 10 seconds, so that the operator is careful not to close the door, window, etc. 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, “Please insert the card” is displayed on the display device 28.
Is displayed and the operator is instructed to insert the 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, the error of the card is indicated to the operator, and the flow returns to step 601 in FIG.

At step 704, the four-digit personal identification number, which is an arbitrary combination of the numbers 0 to 9 corresponding to the card, is given to the function switches F1, F2, F3.
Convert to the reference data considering the number assigned at that time. Next, in step 706, it is determined whether or not a personal identification number is set. As a result, when the personal identification number is set, step 7
The flow from 07 to 712 is executed, and when the personal identification number is not set, the process directly proceeds to step 713.

In step 707, the display device 28 displays
“Enter your PIN” is displayed and the operator is prompted to enter the PIN. After that, as shown in FIG. 1, a screen state is displayed showing which numbers the function switches F1, F2, and F3 correspond to, and step 708 is entered. In step 708, the operator waits for the personal identification number to be input using the three function switches F1, F2, and F3, and when the function switch is pressed, the process proceeds to step 709. In step 709, the number of the pressed function switch is stored in the buffer memory (not shown), and step 7
Enter 10.

In step 710, it is checked whether the function switch has already been pressed four times.
When it is four times or less, the process returns to step 708, and when it is pressed four times, the determination result of step 710 becomes YES, and the process proceeds to step 711. In step 711, the contents of the buffer memory in which the data relating to the operation of the function switches F1, F2, F3 for inputting the personal identification number are stored are compared with the reference data obtained in step 704. If both data are the same in step 712, that is, if the input personal identification number is correct, step 713 is entered, while if both data do not match, step 718 is entered.

In step 718, it is judged whether or not there is a mismatch of the fifth time, the number of times of input is counted, and the input of the personal identification number is permitted up to the number of times of input of five. When the number of inputs is less than 5, the display device 28 is displayed in step 720.
“The password is wrong” is displayed and the process returns to step 708. On the other hand, when the personal identification number is input five times, the lockout abnormality process is performed in step 719, the process is prohibited, for example, for 1 minute, and then the process returns to step 601 in FIG.

In step 713, it is determined whether or not the card has been removed. As a result, when the card has not been removed, in step 721, the display device 28 displays "a picture meaning that the card should be removed" to indicate to the operator that the card has been removed and returns to step 713. . When the card is removed, the process proceeds to step 714.

In step 714, the transmitter 3 is requested to start security, and in step 715, the transmitter 3 waits for confirmation of the start of security. 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 716 and 717 via step 715. That is, in step 716, the state flag F is set to "1" to set the security state, and in step 717, the lamp 30 is turned on to indicate that the security system is in the security state, whereby the security system enters the security state.
Then, the process returns to step 601 in FIG.

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

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, the process proceeds to step 903 via step 902 only when the operator inserts the card. Although not shown, when the card is not inserted for a certain period of time, step 60 in FIG.
Returning to 1 is the same as in the case of FIG.

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 prompt the operator to make a mistake in the card, 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.

At step 906, the display device 28 displays
“Enter your PIN” is displayed and the operator is prompted to enter the PIN. Next, in step 907, the operator selects three function switches F1 and F1.
2. Wait for the personal identification number to be input using F3 and F3, and then proceed to step 908 only after the personal identification number is input. When the personal identification number is not entered even after a certain period of time, a step (not shown) returns to step 601 in FIG.

In step 907, 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. Since this determination is the same as that described based on FIGS. 7 and 8, detailed description thereof is omitted here. As a result, when the input personal identification number matches the registered personal identification number, the process proceeds to step 911, but when they do not coincide, the process proceeds to step 908.
In step 908, 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 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, lockout abnormality processing is performed in step 910, the processing is prohibited for, for example, 5 minutes, and then,
Returning to step 601 in FIG.

In step 911, it is determined whether the card has been removed. As a result, when the card is not removed, in step 916, the display device 28 displays a "picture that means remove the card", prompts the operator to forget to remove the card, and returns to step 911. . When the card is removed, the process proceeds to step 912.

At step 912, the transmitter 3 is requested to cancel the security, and at step 913, the transmitter 3 waits for confirmation of the security cancellation. 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. In other words, in step 914, the state flag F is set to “0” to bring the device into the security release state, and in step 915 the lamp 30 is turned off.
The security system is in the security release state. Then, the process returns to step 601 in FIG.

In each of the above embodiments, the case where the present invention is applied to a security system has been described as an example, but the present invention is not applied only to a security system, and it is necessary to verify a personal identification number. Can be widely used for other purposes.

[0048]

As described above, according to the present invention, it is possible to input code information such as personal identification data by using a smaller number of input operation members and judge the suitability of the code information. , Can be simplified.
