Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position of a person in a work area or a moving area and a personal position detecting device used for identifying who the person is.

[Conventional technology]

2. Description of the Related Art Conventionally, an intrusion alarm device, which is provided in a company office, a house, or the like, detects an intrusion of a person into a work area or a living area and issues an alarm accordingly, is widely known. This intrusion alarm device, for example, installs an infrared projector and an infrared receiver opposite to an entrance where people can easily move, and detects when an intruder crosses the infrared beam from the infrared projector, that is, that the beam is blocked. Then, based on the output of the infrared light receiver, a device for issuing an alarm or a personal identification card reading device provided at the entrance for identifying a personal identification card carried by an individual is used to identify the electric lock. It has been proposed that it is locked or unlocked so that only a specific individual can pass through and enter and exit.

[Problems to be Solved by the Invention]

However, such a conventional intruder warning device using an infrared projector and an infrared receiver is sufficiently effective when used for intruder security in an unattended state at night. Both intruders and unauthorized persons detect both intrusions and give an alarm, which is ineffective for use where people move frequently. In addition, an intrusion warning device that reads a personal identification card with a personal identification card reader can distinguish between those who are permitted to enter and those who are not permitted to enter, so that unauthorized intruders can be correctly identified. The entry door opened by a person who has been permitted to enter, who overlooks the person who is not permitted to enter and exit following the person who is permitted to enter and exit, There was a problem that the situation afterwards could not be grasped at all.

The present invention has been made in view of the above-mentioned conventional problems, and makes it possible to determine at which position in a setting area a specific individual who is permitted to go in and out of the setting area is required. Accordingly, it is an object of the present invention to obtain an individual position detecting device capable of detecting an individual who is not permitted to go in and out according to the above and issuing an alarm.

[Means for solving the problem]

The personal position detecting device according to the present invention is provided with a personal position identifying means having a person presence / absence detector, a personal data detector and a position detector at a plurality of locations on a floor, and output data of the personal position identifying means by a computer, By comparing with the individual identification reference data stored in the memory, it is possible to determine which of a plurality of places a specific individual is,
Further, the determination result is displayed on the display device. Further, an alarm device is provided which is activated when the output data and the personal identification reference data do not match to give an alarm.

[Action]

The individual position identifying means according to the present invention identifies, when a specific individual enters a predetermined area on the floor, where the person moves, that the individual has entered the predetermined area, the position at which the individual entered, and the individual. Each signal is output, and the computer compares these signals with the reference signal specifying the person who is the reference signal and the reference signal specifying the position, and when they match, it is determined that the person is permitted to enter and exit, for example. It is judged and displayed on the display. If they do not match, it is determined that the person is not authorized to enter and exit, and these are displayed on the display device, and the alarm device is activated to issue an alarm.

〔Example〕

An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, 1a to 1n are individual position identifying means installed at a plurality of places on the floor of a building where people come in and go out. This means that a person is in a specific area of the floor, for example, weight (load).
The presence / absence detector 2 for detecting a person, the personal data detector 3 for detecting the content of the personal identification certificate carried by the person, and identifying the specific individual, and the position of the floor where the person is Position detector 4 for detecting a region). Reference numeral 5 denotes a computer, which obtains personal position data from the detection data obtained from the presence / absence detector 2, the personal data detector 3 and the position detector 4 by the microprocessor 6,
The personal identification reference data stored in advance in the memory 7 is compared with the obtained personal position data. Reference numeral 8 is a display device for displaying this comparison result, and 9 is an alarm device which operates when it is determined from the comparison result that the two data do not match.

 Next, the operation will be described.

For example, the individual position identifying means 1a to 1n as shown in the figure are attached to the floor of a room where people enter and leave, for example, on the lower surface of the floor board by a method that cannot be easily seen by the eyes. Now, a person who is permitted to enter or leave this room carries a personal identification certificate having a specific ID number into the room and reaches one of the specific positions of the room, for example, the personal position identifying means 1a. Then, first, the presence / absence detector 2 detects the weight of the person or the individual, and determines that the person is at this position.

At the same time, the personal data detector displays the ID number (ID
Data) is detected by electrical, magnetic or optical methods. Further, the position data of the personal position identifying means 1a is constantly detected by the position detector 4, and each of these detection data is input to the computer 5. In this computer, the personal identification reference data stored in advance in the memory 7 is referred to, based on each of these detection data, that a person is at a predetermined position on the floor, and the name of that person is specified. , And where the person is, and finally the position where the specific individual is (the person is on the personal position identification means 1a) is determined.
Then, this determination result is input to the display device 8 and the position of the individual in the room can be displayed here in a state in which it can be predicted where this individual will move next. In this case, the moving direction of the individual is not constant, but if the number of times of movement at each position is counted, the activity range and situation of the individual can be easily grasped, and thus the behavior of the individual can be grasped. It will be possible.

On the other hand, in the case of entering or leaving the room without carrying the personal identification certificate, if the individual reaches any of the personal position identifying means 1a to 1n, any one of the personal position identifying means 1a to 1n as described above. From the above, various detection data similar to the above are input to the computer 5. However, since personal identification reference data for identifying an individual is not stored in the memory 7 of the computer 5, the respective data do not match, the result is displayed on the display device, and the alarm device 9 is activated. And warns that an outsider has entered the room.

As described above, according to the present invention, it is possible to identify an individual, identify the position where the individual is, and predict the direction and the position where the individual is about to move.

In the above embodiment, the personal position identification means 1a to 1n are provided on the floor, but if the same data can be obtained, the same effect can be obtained on the wall, the ceiling or any other. Can be obtained.

Further, as the alarm device 9, a device displayed by sound or light can be arbitrarily selected and used. Further, when there is a door, only the one which is permitted to enter and exit is interlocked with the electric lock. You can also choose to do so.

Furthermore, the personal identification reference data can be set freely and easily on the computer 5 side, and in addition, the setting data can be changed between nighttime and daytime to enable flexible operation of the system. become.

〔The invention's effect〕

As described above, according to the present invention, a human presence detector,
Personal data detectors and personal position identifying means having position detectors for constantly detecting the position of a person are provided at a plurality of locations over the entire floor of a predetermined area, and the output data of the personal location identifying means by a computer and a memory. By comparing with the personal identification reference data stored in, it is possible to determine which of a plurality of places a particular individual is, and the result of this determination is displayed on a display device. It is possible to automatically identify whether or not a person has entered and left, whether or not the person is a predetermined person who is permitted to enter and exit, and who is the person.

The conventional intruder detection device operates the personal data detector only after detecting the intruder by infrared rays or the like, and the intruder detector is provided in a limited part such as near the entrance. On the other hand, the personal position identifying means of the present invention is not limited to the vicinity of the entrance, but is provided at a plurality of places on the floor inside the building, and the position detector always detects the position of the person. Even when and where an intruder intrudes into the building, it can be detected without omission.

Further, according to the present invention, when the person is not a person who is previously permitted to go in and out, there is an effect that an alarm can be issued to notify the intrusion of an outsider.
