Abstract

PROBLEM TO BE SOLVED: To prevent a third person from performing an illegal security release operation by designating 2nd data from prescribed data on the basis of a prescribed generated random number when deciding that a 1st input exists, deciding the existence/absence of 2nd data input to a security state switching means and controlling a security state. SOLUTION: A device first decides whether 1st data is inputted. That is, the inputted 1st data are compared with corresponding data preliminarily stored in a storing part 11, and when they are the same, the device decides that the data is inputted. Next, when a controlling part 6 decides that the data coincide with each other in comparison decision, the part 6 selects specified data as 2nd data from a plurality of pieces of data which are made to correspond to individual identification information included in the 1st data and are stored in the part 11 on the basis of the random number obtained from a random number generating part 10. Subsequently, an input request for the 2nd data is notified from a displaying part 5 or a sound outputting part 8. Then, when the part 6 decides that the 2nd data is inputted within an input allowable time, the security state is released.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security terminal device for transmitting monitoring information from a sensor disposed at a security target facility to a monitoring center.

[0002]

2. Description of the Related Art A sensor is disposed at a security target facility such as an office or a school, and when an abnormality occurs in the facility during a predetermined security time period such as at night, an abnormal situation is reported to a monitoring center. A system in which a surveillance center makes a security officer rush to the target facility has become widespread.

In a conventional system, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 97997, a security release prohibition time zone is set in advance to prevent damage caused by an unauthorized security release by a third party, and the security state is released even if an attempt is made to release the security state I cannot do it.

[0004]

In the above system, the effect of preventing an unauthorized security release operation by a third party is recognized. However, for example, when a person involved in the security target facility intends to release the security state during a security time period (or a security release prohibition time period), it is necessary to contact the monitoring center and request an operation for security release. This procedure is complicated, and it is also necessary to identify whether the requester of the security release is truly a relevant party.

[0005] For this reason, the present invention provides a security terminal device which makes it difficult for a third party to perform an unauthorized security release operation, and in which a designated person in advance can easily release the security without contacting the monitoring center. With the goal.

Further, the present invention provides a system in which a final exit from a security target facility can re-enter the same facility with a simple operation, and monitoring when a person involved in the security target facility is forced by a third party to release security. An object of the present invention is to provide a system capable of notifying a center of an emergency.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a security terminal device connected to a sensor for detecting an abnormality and security state switching means and transmitting information to a monitoring center. A storage unit for holding data,
A random number generator, and a controller, wherein the controller determines whether or not first data has been input to the security state switching means during the security operation of the security terminal device, and determines that the first data has been input. A second data is specified from a plurality of predetermined data held in the storage unit based on a random number generated from a random number generation unit, and it is determined whether or not the second data is input to the security state switching unit. Controls security status.

Specifically, the control unit performs control to release the security state when it determines that the first data has been input and determines that the second data has been input within a predetermined time. When it is determined that the first data has not been input, or when it has been determined that the second data has not been input within a predetermined time, control is performed to maintain the security state. Further, the control unit may be configured to input a second data specified based on a random number after the input of the first data.
Control for notifying the input request of the data.

The first data is data containing personal identification information of an operator specified in advance, and a plurality of predetermined data specified in accordance with a random number generated in a random number generation unit and held in a storage unit. The data includes data relating to the operator.

Further, when the security terminal device is switched to the security operation by inputting data including the personal identification information of the operator to the security state switching means while the security terminal device is in the security release operation, the security terminal device is set within a predetermined time thereafter. When data including the personal identification information of the operator is input, the control unit performs control to cancel the security operation if it is determined that the two input personal identification information match. When the first data or the second data and a predetermined data other than the first data or the second data are input to the security state switching means, the control unit performs control to cancel the security operation and notifies the monitoring center of an emergency.

[0011] According to these inventions, it becomes difficult for a third party to illegally release security to a security target facility, and a person concerned can easily release security. In addition, the last exiting person can easily re-enter within a predetermined time, and when the security operation is canceled by a third party, an emergency situation is notified to the monitoring center.

FIG. 1 shows a configuration example of a security terminal device according to the present invention.

The security terminal device 1 is connected to sensors S1 to Sn for transmitting information via a sensor interface unit 2, and is connected to security status switching means SW1 to SWn via a security status switching interface unit 3. I have. FIG. 1 shows an example in which a plurality of sensors and a plurality of security state switching means are provided, but one or both of them may be provided depending on a monitoring target. The security terminal device 1 is a communication line interface 1
2 and a monitoring center via a communication line.

The security terminal device 1 includes a control unit 6 which controls and processes various information transmitted from the sensor and the security state switching means based on predetermined setting conditions, and transmits information to a monitoring center when necessary. .

The security terminal device 1 further comprises an operation unit 4 for inputting various data to the device and setting conditions, a timer 9, a random number generation unit 10, and a storage unit 11 for storing various data.
Is provided. Various data can be input and stored in the storage unit 11 from the operation unit 4 or by another means. These data include, for example, personal identification information of a person who is permitted to enter and exit the security target facility, another plurality of data related to each of these individuals, and a time when the timer times out. This related plural data is usually the person's telephone number, address number, family name, date of birth (the date of birth must not be indicated on the ID card etc.) Is data that can be immediately recalled, and is not easily and immediately understood by a third party.

The control unit 6 includes a display unit 5 for performing various displays.
It is connected to a voice generating unit 7 for generating a voice message and a buzzer sound, and a voice output unit 8 for outputting a voice message and a buzzer sound to the outside. The display unit 5 and the audio output unit 8 are arranged near each security state switching unit.

For example, the timer 9, the random number generator 10, the storage unit 11, and the like can be formed in a microcomputer constituting the control unit 6.

The security state switching means SW1 to SWn can input personal identification information of the operator. For example, a device for reading a medium such as a magnetic card, an IC card, a card using optical information, or a numeric keypad input device, or the like, or a configuration including both the reader and the numeric keypad device is also possible. Other devices capable of personal authentication, such as a fingerprint identification device, are also possible. Various sensors such as an optical sensor, an ultrasonic sensor, and an acoustic sensor can be used as the sensor.

Next, an example of the operation of the security terminal device will be described with reference to a flowchart.

FIG. 2 shows an operation for canceling the security state while the security terminal device 1 is performing a security operation. The operator first operates the security state switching means as a first security release operation.
(Always include the operator's self-identification number). Specifically, there is a method in which an operator passes his / her ID card (for example, a magnetic card) through a reading device, or a method in which an operator inputs his / her own identification number from a numeric keypad. Also, a method may be used in which both the self-identification number and the input of a specific password are required. Further, predetermined operations (such as input of another code, pressing of a button, and the like) may be combined.

Next, the controller 6 determines whether the first data has been input (whether the first data has been input effectively) (step 200). For example, the first input
Are compared with the corresponding data stored in the storage unit 11 in advance, and if they are the same, it is determined that there is an input (YES in step 200). The control unit 6 determines that there is no input of the first data when there is any data input to the security state switching unit, but when it is determined that the data do not match in the above-described comparison determination, The security state of the security terminal device 1 is maintained (N in step 200).
O).

When the control unit 6 determines that the data match each other in the above-described comparison determination (YES in step 200), the control unit 6 generates a random number from the random number generation unit 10 and generates a random number based on the obtained random number. Specific data is selected as second data from a plurality of data held in the storage unit 11 in association with the personal identification information included in one data. Thereafter, the display unit 5 and the audio output unit 8 are arranged near the security state switching means SW to which the first data has been input.
Is notified of the input request for the second data (step 201). Assuming that the number of the specific data designated by the random number is 3, the security terminal notifies the user to input the third date of birth as the second data. Upon receiving the notification of the input request, the operator inputs his / her date of birth using, for example, a numeric keypad. The generation of random numbers is performed every time the first data is input.

When the input instruction of the second data is notified, the timer 9 for measuring the time during which the input of the second data is possible starts. An authorized operator who has entered the first data can easily remember his / her date of birth, etc. in a short time and can easily input it, but a third party must input these data within a specified short time Is almost impossible. The timer 9 can be started, for example, from the first data input confirmation.

If the control unit 6 determines that the second data has been input within the inputtable time, it releases the security state and transmits the release state to the monitoring center (step 205). The input of the second data can be performed any number of times before the timer 9 times out, but when the time is up, the control unit 6 invalidates all of the data even if the second data is correctly input, and the security terminal device is disabled. (Step 204).

As described above, the security terminal device can easily release security by inputting personal data if it is a person registered in advance, but a third party can select the security terminal device based on a random number each time. It is almost impossible to release security because the personal data of the person is not easily known.

Next, a case will be described with reference to FIGS. 3 and 4 in which the last exiting person exits and re-enters a security facility within a predetermined time after starting security.

In FIG. 3, when the security operation is released, the security terminal device 1 performs an operation during a predetermined security release.

First, the control unit 6 sends a plurality of security status switching means SW 1 to SW via the security status switching interface 3.
The security start operation performed on any of n is recognized (step 300). In the security start operation, the self-identification number of the last exited person is always input. At this time, the control unit 6 sets the security terminal device 1 in a security state, and transmits security start information from the communication line interface 12 to the monitoring center via the communication line (step 301). Further, the control unit 6 stores the personal identification information of the last exited person input from the security state switching means in the storage unit 11 of the security terminal device 1, and starts the timer 9 to measure the alarm release permission time (step 301). ).

Next, the last exiting person sends the first state to any of the security state switching means within the alarm release permission time.
When the control unit 6 receives the data (including its own identification information), the control unit 6 recognizes this (step 302), and determines whether the person who performed the input operation is the last exited person by determining whether the personal identification information matches. (Step 304).
When the control unit 6 determines that the final exit has been made,
The security state is released, and the release is transmitted to the monitoring center (step 309).

If no data is input within the predetermined alarm release permission time, the security terminal device 1 returns to the original security state (YES in step 303).

Although some data is input within the security release permission time, the data does not match the personal identification information of the last exiting person, and unless the person who made this input is the above last exiting person. When it is determined, as described in the flow of FIG. 2, second data is designated based on a random number from a plurality of data relating to the last exited person (stored in the storage unit 11), and the designated second The request for inputting the second data is notified from the display unit 5, the audio output unit 8, and the like (step 30).
5). At this time, the timer is started as described above (step 305).

Even if the person who made the erroneous data input performs the input operation of the second data relating to the last exiting person effectively according to the request (step 306), the security state is released and simultaneously released. Is transmitted to the monitoring center (step 309). However, since the input of the second data can normally be performed only by the last exiting person, those who are not the last exiting person cannot release the security state and enter the area.

It is determined that all operations after the timer count has expired are invalid (step 30).
8) The security terminal device 1 is in a security state. In this way, the final exit person can re-enter the security target facility by a simple operation within a predetermined time. However, those who are not the final exit are required to perform a normal security release operation. For this reason, registered persons of the facility can enter by almost normal security release operation, but a third party cannot release security and cannot enter.

Next, a person who can enter a security target facility registered in advance (that is, registered in the storage unit 11) is compelled by a third party (eg, a robber) to release the security state. The operation in this case will be described. As shown in the flow of FIG. 5, when a third party compels a normal first data input operation (step 200), the operator performs an emergency input (step 300-A). This emergency operation is performed, for example, by using a specific symbol (for example, #, *, etc.) that is different from the usual symbol used to determine the ID number or password, or by using a specific number, character, symbol, etc. There is a method of inputting in addition to a password. Alternatively, a method of combining operation and pressing of another button or the like can be considered. When the emergency operation is performed, the security state is released and, at the same time, the fact that the security is released in the emergency is transmitted to the monitoring center (step 206).

The same applies to the case where the last exiter is forced by a third party to release the security state. After inputting the start of security, the first security release operation is performed within a predetermined time, and when the above-described emergency operation is performed along with this, the security state is also released as shown in FIG. At the same time, the fact that the security has been released in an emergency is transmitted to the monitoring center (step 206). In FIG. 5, each step other than the emergency operation step is the same as in FIG. It should be noted that the emergency input can also be performed at the time of the second data input.

The monitoring center knows that an emergency has occurred in response to the emergency transmission, and can immediately send a security officer to the target facility and take other emergency measures.

The identification number of the operator who releases the security status can be stored in the security terminal device or transmitted to and registered in the monitoring center (or both can be performed).

[0038]

As described above, according to the present invention, when the security state of a security target facility is released, the operator who inputs the first data including the personal identification information can be used without requesting the monitoring center to release the security state. From multiple related and highly authenticated data,
Specific data is specified by a random number each time the operation is performed, and by requesting input of the specified second data, even if a third party can input the first data,
It is possible to prevent the security of a third party from being released, and it is possible to expect an effect of preventing crime in advance.

Further, according to the present invention, the last exiting person can easily re-enter within a predetermined time after the exit, and when the security state is released by a third party's compulsion, emergency information is sent to the monitoring center. Sent.
