Description

  The present invention relates to an alarm system that issues an alarm to an illegal intruder who attempts to enter a building or room.

  2. Description of the Related Art Conventionally, an entrance / exit management system in which an authentication device is installed on a wall surface of a building or facility is known in order to manage a user's entrance / exit to a building or facility. This authentication device compares the identification number for verification recorded in a recording medium such as an IC card of the user with the registration identification information registered in advance in the authentication device, and the identification number and the registration identification number If "and" match, the user is authenticated as a legitimate user.

  On the other hand, if the registration identification information registered in advance in the authentication device and the identification number of the IC card do not match, the target user is not allowed to enter the building or facility. It is considered authentication. In this way, the authentication device confirms the legitimacy of the user based on the collation result between the identification number of the IC card and the registered identification number, and determines whether or not the user can enter and leave the room.

Such an authentication device may be removed from a state where it is installed on the wall surface due to illegal intrusion or mischief. Therefore, if the user destroys the authentication device, attempts to enter the room using unauthorized means, or releases the mechanism, the camera will capture the image and face of the fraudster. An exit management system is disclosed in, for example, Prior Art Document 1.
JP 2004-208244 A

However, according to the configuration of Prior Art Document 1, it may lead to the identification of a criminal offender and may be beneficial in crime prevention, but it is not configured to prevent vandalism itself.

  The present invention is intended to solve such problems, and provides an alarm system that can prevent doors, walls, authentication devices, etc. from being damaged or mischief by illegal intruders to buildings or facilities. One of the purposes.

The present invention made in view of the above problems is an authentication device that is provided near a door for entering a facility and reads the personal information of the user according to the user's authentication operation using an authentication medium. And an entrance / exit control device that manages the locked state of the door based on the personal information, a first sensor that detects vibration applied to the authentication device, and a second sensor that detects vibration applied to the door, The alarm means generates an alarm when at least one of an alarm means for issuing an alarm, an output of the first sensor, and an output of the second sensor exceeds a predetermined threshold value. Alarm start / stop means for controlling, and the alarm start / stop means continues to issue the alarm based on the similarity between the output of the first sensor and the output of the second sensor. It is characterized by judging whether or not It is a warning system that.

According to the present invention, the door for entering the facility, the authentication device is damaged, or the user who performs mischief is configured to issue an alarm. Can be reduced. In addition, in order to determine whether or not to continue alarming based on the similarity between the outputs of the first and second sensors, for example, when vibrations associated with natural phenomena such as earthquakes are detected, It is possible to stop the alarm.

[First embodiment]
Hereinafter, an alarm system according to an embodiment of the present invention will be described with reference to the drawings. In the drawings, corresponding parts are denoted by the same reference numerals, and overlapping description of such parts is omitted.

<Whole structure of alarm system>
As shown in FIG. 1, an alarm system 1 according to an embodiment of the present invention includes an authentication device 2 for performing authentication operation by a user provided near the entrance to the facility F, and for entering and exiting the facility F. The door 3, the electric lock 4 provided on the door 3, and the authentication device 2 are connected by communication, and the entrance / exit control device 5 that controls the opening / closing of the electric lock 4 based on the result of the user's verification in the authentication device 2, The exit control device 5 and the monitoring device 6 connected by communication. A first sensor 7 a that detects vibration of the authentication device 2 and a second sensor 7 b that detects vibration of the door 3 are provided in the vicinity of the authentication device 2 and the door 3.

<Authentication device>
The authentication device 2 reads personal information (for example, employee name and employee number) of the user when an IC card or the like as an authentication medium owned by the user is held over. The read personal information is transmitted to the entrance / exit control device 5 described later. As the authentication device 2, in addition to the card reader, a fingerprint authentication device, a face authentication device including iris recognition, and the like can be used. In this case, the authentication medium is a user's fingerprint and facial parts.

<Entry / exit control device>
The entrance / exit control device 5 determines whether the user can enter the room based on the personal information of the user transmitted from the authentication device 2. The entrance / exit control device 5 stores in advance personal information of a user who is permitted to enter the facility F, and the personal information of the user transmitted from the authentication device 2 and the stored personal information. Verification is performed. If the user is allowed to enter the room as a result of the collation, a signal for releasing the lock of the electric lock 4 provided on the door 3 is output. The door 3 may be an automatic door that is automatically opened when the user is permitted to enter the room, or the door 3 is unlocked for a certain time and the user himself opens the door. It may be a configuration.

<Monitoring device>
The monitoring device 6 is used for operation control of facilities installed in the facility F and monitoring and management of the entire building, and is installed in a central monitoring room in the building, for example. In monitoring and managing the entire building, the operator can monitor a plurality of facilities F individually while operating the screen of the monitoring device 6.

<Sensor>
The sensors 7a and 7b detect applied vibration, and for example, a vibration sensor or an acceleration sensor is used. A signal indicating the vibration detected by the sensors 7a and 7b is transmitted to a CPU (not shown) provided in the authentication device 2. Thereby, when vibration of the door 3 and / or the authentication device 2 is detected, the authentication device 2 determines whether the door 3 and / or the authentication device 2 is externally pressured. Is done. Details of this operation processing will be described later.

<Operation in alarm system>
Next, in the alarm system 1, a processing operation when an unauthorized person or the like is going to cause harm to the authentication device 2 or the door 3 will be described with reference to the flowchart of FIG.

  First, verification by the authentication device 2 installed in the vicinity of the door 3 is performed, and the entrance / exit control device 5 determines whether or not the user is allowed to enter the facility F (ST1). ). When the user is not permitted to enter the facility F, the output of the first sensor 7a for detecting the vibration of the authentication device 2 and the output of the second sensor 7b for detecting the vibration of the door 3 are provided. The authentication device 2 acquires (ST2).

In ST1, when the door 3 is locked, vibrations may be detected by the opening / closing operation of the door 3 by the user, and therefore the processing after ST3 described later is not performed. At this time, the first and second sensor outputs of the authentication device 2 are not acquired, and the determination as to whether or not the door 3 is locked is repeated.

  In ST2, when the authentication device 2 acquires the output of the first sensor 7a and the output of the second sensor 7b, the authentication device 2 in at least one of the first sensor 7a and the second sensor 7b, It is determined whether the vibration of the door 3 is detected (ST3). If no vibration is detected in any of the authentication device 2 and the door 3, the process returns to ST1. The vibration detection described here is an output in which at least one of the output of the first sensor 7a and the output of the second sensor 7b exceeds a predetermined threshold. Indicates. That is, the threshold value may be set so that the first and second sensor outputs do not exceed the threshold value as long as the user touches the door 3 or the authentication device 2.

  In ST3, when vibration is detected in at least one of the output of the first sensor 7a and the output of the second sensor 7b, an alarm is issued by an alarm means (not shown) (ST4). . The alarm means may be anything that can output a buzzer, for example. However, the alarm means is not particularly limited as long as it can threaten persons in the vicinity of the authentication device 2.

  Further, after an alarm is issued in ST4, it is determined whether or not the output of the first sensor 7a is similar to the output of the second sensor 7b (ST5). Here, if it is determined that the output of the first sensor 7a and the output of the second sensor 7b are similar, it is determined that the vibration is a vibration due to a natural phenomenon such as an earthquake, and ST4 Then, the alarm issued by the alarm start / stop means (not shown) is stopped (ST6). Various methods can be used to determine whether or not the output of the first sensor 7a is similar to the output of the second sensor 7b. For example, it is possible to determine the similarity by taking a cross-correlation with the signal waveforms of the first sensor 7a and the second sensor 7b shown in FIG. When it is determined that the signal waveforms of the first sensor 7a and the second sensor 7b are similar after a predetermined time t1 has elapsed since the vibration was detected, an alarm is started and stopped at that time. What is necessary is just to stop the alarm by a means. The alarm issuing / stopping means may be provided in the authentication device 2, but may be provided in the entrance / exit control device 5.

On the other hand, when it is determined that the output of the first sensor 7a is not similar to the output of the second sensor 7b, the vibration is determined to be intentionally caused and the entrance / exit control is performed. The monitoring device 6 is notified via the device 5 (ST7). Based on the information notified to the monitoring device 6, an operator in the central monitoring room can recognize the presence of an unauthorized person in the facility F. At this time, the alarm issued in ST4 is continued without being stopped. Here, after the processing in ST5, the notification is made to the monitoring device 6 in the central monitoring room, but at the same time as the alarm is issued in ST4, the monitoring device 6 in the central monitoring room is notified. You may do it.

  As described above, in the alarm system according to the embodiment, since it is possible to detect both the act of opening the door 3 and the act of removing the authentication device 2, It is possible to detect an act of destroying the worm at an early stage, and to appropriately warn and intimidate an illegal person.

As mentioned above, although the alarm system of this invention was demonstrated by embodiment, the description and drawing which make a part of this indication do not limit this invention. It goes without saying that various embodiments are included without departing from the scope of the present invention.
