JPH0519047A - Entering/leaving time management system using mobile body identification device - Google Patents

Abstract

PURPOSE:To enable a specified amount of time lapse to be reported to a mobile body without any contact after it enters a specified area. CONSTITUTION:A needed information is read from an answering device 2a which an entering person 3a has by an interrogation device 1a. When a certain amount of time passes after entering, a signal which activates a reporting means such as a buzzer is sent from the interrogation device 1c to the answering device 2c of an entering person 3c without any contact. When the interrogation device is installed, it is possible to report that a certain amount of time passed without any contact wherever the entering person may be located. Also, by assigning an identification number which is peculiar to each answering device, a plurality of mobile bodies can be time-managed simultaneously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for individually managing the entering / leaving time of a moving body moving in and out of a specific area by using a moving body identifying device. For example, it is impossible to work for a long time. It can be used for dangerous work sites, time-based entertainment facilities, etc.

[0002]

2. Description of the Related Art Conventionally, with respect to a transponder held in a moving body, an identification number of the transponder is read or data is written into the transponder by using a non-contact communication means such as radio waves from an interrogator. A moving body identification device is known. FIG. 4 shows a schematic configuration of a conventional mobile body identification device. 1 in the figure
Is an interrogator, 2 is a responder, Q is an interrogation signal, and A is a response signal. In the interrogator 1, 10 is a data control / processing circuit, 11 is a modulator, 12 is a demodulator, 13 is a transmitting antenna, 14 is a receiving antenna, and 15 is a receiving amplifier.
In the responder 2, 20 is a data control / processing circuit, 21
Is a modulator, 22 is a demodulator, 23 is a transmitting antenna, 24 is a receiving antenna, and 25 is a receiving amplifier. Using such a moving body identification device, an interrogator 1 is made to hold an responder 2 by an in-room person, and the interrogator 1 installed at a place through which the in-room person passes can identify from the responder 2 held by the in-contact person in a non-contact manner. There has been proposed an entry / exit management system that reads a number, information written in advance, and the like, and manages the entry from the entry of a person to the exit of the room. Such an entrance / exit management system is used, for example, in the security field.

[0003]

However, in the conventional system, the communication status and the content of information are managed only on the side of the interrogator 1, and what information is stored on the side of the responder 2 held by the occupant. I couldn't even know. Therefore,
In the case of managing entry / exit time for a specific area, the questioner 1 cannot inform the person who has the responder 2 that a certain period of time has passed since the person entered the room. was there.

The present invention has been made in view of the above circumstances. An object of the present invention is, in an entry / exit time management system using a moving body identifying device, when a moving body enters a specific area. It is to be able to inform the moving body of non-contact of the lapse of a predetermined time from.

[0005]

In order to solve the above-mentioned problems, an entrance / exit time management system using a moving body identifying apparatus according to the present invention, for example, as shown in FIG.
Responders 2a, 2b, 2c in which the persons 3a, 3b, 3c entering and leaving the specific area 4 carry the information, and the responders 2a, 2b, 2c in which the required information is written and the locations where the persons 3a, 3b, 3c pass An interrogator 1a, which is installed and can read the information written in the responders 2a, 2b, 2c in a contactless manner,
1b and 1c, and when a certain time has passed from the time of entering the room, the interrogators 1b and 1c to the responder 2b, as necessary.
The responders 2a, 2b, 2c have a notification means such as a buzzer for sending the signal to the room 2c to notify the occupants 3b, 3c that the time has come.

[0006]

In the system of FIG. 1, the respondent 2a held by the occupant 3a by the interrogator 1a receives the name of the occupant from the responder 2a.
Read other necessary information. Then, with respect to the responder 2c after a certain time has elapsed after entering the room, the interrogator 1c sends a signal of a command to sound the buzzer to the responder 2c with a buzzer carried by the person 3c who enters the room, and the buzzer is activated. It sounds to notify the occupant 3c that a certain time has passed. Also, by using the interrogator 1a, the exiter's name and other information are read from the responder possessed by the exiter, and the exit time is also stored individually, so that it is possible to determine whether the exit has actually occurred. Can be managed.

[0007]

EXAMPLE FIG. 2 shows an example in which the entry / exit time management system of the present invention is applied to a dangerous work site such as a nuclear power plant or a coal mine where long working hours cannot be performed. When the worker 3e enters the work site 5, the operator's name and other information relating to health management are read from the responder 2e carried by the worker 3e in a non-contact manner using the interrogator 1e and stored together with the time of entry. I'll do it. Then, the time elapsed since the workers 3d, 3e, 3f enter the work site 5 is individually managed, and there is the worker 3f who has left a predetermined time after entering and has left time. If so, the operator 3f rather than the interrogator 1f
Transmits a signal of a command to sound the buzzer to the responder 2f with a built-in buzzer carried by the operator to notify the worker 3f that the exit time has come. The worker 3f can know that the exit time has come by sounding the buzzer of the transponder 2f carried by him / her, and immediately exits. And the interrogator 1e
On the side, the exit time is also managed individually to check whether the person has actually exited and manage the entry / exit time of the worker.

Next, FIG. 3 shows an embodiment in which the entry / exit time management system of the present invention is applied to a time-based entertainment facility. As an example of a time-based entertainment facility, there are various ones such as a billiard field, a fitness club, a karaoke box, and a pool. Here, a stadium in a general sports park will be described as an example.

Players 3g and 3h receive portable transponders 2g and 2h when entering the sports park,
Enter the park. At this time, the manager of the sports park writes the player's name, personal data, etc. in the responders 2g and 2h from the interrogator installed at the entrance, and checks the entrance time individually. The player can freely use the exercise park within a certain fixed time. After a certain fixed time has passed, the administrator side uses the interrogator 1g installed at each location to turn off the signal of the command to ring the buzzer to the responder 2g with the buzzer carried by the player 3g. Send by contact. Transponder 2
The g can receive this signal and sound the built-in buzzer to notify the player 3g.

The players 3g and 3h read the information written in the memory of the responders 2g and 2h at the toll gate where the interrogator is installed, and pay the fee for the used time. The manager of the sports park also manages the exit time individually, and manages the entrance and exit times of the sports park users.

[0011]

According to the entry / exit time management system using the moving object identifying apparatus of the present invention, if a questioner is installed, a certain period of time has passed without contact, no matter where the occupant is. This has the effect of letting you know. Moreover, since a unique identification number can be assigned to each responder, time management of many humans can be performed at the same time. In addition, when using this system for a time-based service industry, an entertainment facility, etc., not only time management for entering / leaving the room but also user charge management can be performed at the same time.
