The present invention relates to devices, and particularly to a security device that performs the above-mentioned restriction and monitoring using a name tag built into a transmitter.

Conventional technology In order to restrict and monitor the access of outsiders to protected areas in offices, factories, research institutes, etc., electric locks are installed on the entrance/exit doors of protected areas, and magnetic card identification cards, or so-called ID cards, are installed on the entrance/exit doors of protected areas. This method of opening and closing electric locks is widely used. ID
For outsiders such as foreigners who do not have cards,
The name and time of visit of the person who is permitted to enter the protected area (hereinafter referred to as a qualified person; outsiders who are not permitted to enter the protected area are referred to as an unqualified person) must be submitted in advance at reception. A method has been put into practical use in which outsiders are allowed to enter after registering and determining whether they are qualified based on reservation documents or name tags they carry.

Japanese Patent Application No. 58-243125 filed by the applicant
-138180) "Building door opening/closing management system" and Japanese Patent Application No. 1983-243126 (Japanese Patent Application No. 1983-134965)
The "Visitor Reservation Management System" discloses a specific example of a method for registering qualified persons at the reception desk in advance.

However, the above conventional method requires all full-time employees to
There is the hassle of having to carry an ID card at all times,
It is more convenient to exclude only unqualified persons from doors that are regularly used by most full-time employees, and the protected door remains open for a certain period of time when an ID card is used, allowing unqualified persons to enter during that time. ,
Management using ID cards, name tags, reservation documents, etc.
Although it is possible to manage the arrival and departure times of full-time employees and the names and arrival and departure times of visitors, there are problems such as the inability to manage the movement routes of people within the protected area.

These problems can be solved if there is a means to detect unauthorized persons at the entrance to protected areas.
There was a desire to develop a means to electronically automatically detect unqualified persons.

Problems to be solved by the invention Therefore, the problems to be solved by the invention are as follows:
The object of the present invention is to provide a means for electronic detection of unauthorized persons in a protected area to solve the above-mentioned problems of the prior art.

Means for Solving the Problems Referring to FIGS. 1 to 4, the security device using a name tag built into a transmitter according to the present invention includes a name tag 1 attached to a person H who is not allowed to enter a protected area P. , a sensor built into the name tag 1 that detects whether the name tag 1 is attached to a human body and generates an output;
A transmitter 4 that is built into the name tag 1 and emits different wave signals S depending on the presence or absence of the sensor output, and a wave signal detector that is installed in the protected area P and generates different output signals in response to the different wave signals S. 6, and a safety switch device 7 connected to the wave signal detector 6 and responding differently to different output signals of the wave signal detector 6.

Effects Referring to Figures 1 and 4, if a person H who is not allowed to enter the protected area P, i.e. an unqualified person, approaches the protected area P while wearing a name tag 1, the person H
A wave signal detector 6 detects a wave signal S, such as an electromagnetic wave or an ultrasonic wave, which is unique to each name tag 1 and emitted from the name tag 1 attached to the name tag 1 . Wave signal detector 6
The output is applied to the safety switch device 7 via the electric wire L1 shown in solid line in FIG. In the illustrated example, the indicator light 8 is directly connected to the safety switch device 7,
The security switch device 7 further connects a buzzer 9 and an electric lock 10 to a door 11 etc. via electric wires L2 and L3.
connected to.

Therefore, in response to the detection of the wave signal by the wave signal detector 6, the indicator light 8 and buzzer 9 will display and warn the approach of an unqualified person, and at the same time, the electric lock 10 will be locked to prevent the unqualified person H from approaching. Prevent entry.

The security switch device 7 may be built into the buzzer 9 and/or the electric lock 10 and directly drive them. It is convenient to install the indicator light 8 in a reception area or a monitoring room so that a supervisor such as a guard can monitor it.

A sensor (not shown) for detecting whether or not the name tag 1 is attached to the body of a person H is built into the name tag 1. This sensor detects, for example, heat rays from the human body to name tag 1 or electrostatic capacitance to the human body, and generates an output when name tag 1 is attached to person H, and when name tag 1 falls from person H. No output is generated at this time. The transmitter 4 emits a wave signal S that varies depending on the presence or absence of an output from the sensor, for example, a wave signal S having a different frequency. The wave signal detector 6 detects different wave signals S and operates the corresponding safety switch devices 7. That is, when the wave signal S indicates the name tag 1 attached to the person H, the security switch device 7 locks the electric lock 10 and prohibits the person H from entering the protected area P, for example. When the wave signal S indicates the name tag 1 that has fallen from the person H, the security switch device 7, for example, notifies an appropriate monitoring device, security guard, etc. (not shown) of the detection of the name tag 1.

Embodiment An embodiment of the name tag 1 used in the present invention is shown in FIGS. 2 to 4. A transmitter 4 and a power source 5 are interposed between two decorative boards 2 and 3, and both decorative boards are fixed by screws 1b screwed into screw holes 1a. This transmitter 4 is driven by a power source 5 and emits a wave signal S to be detected by the wave signal detector 6 of FIG.

The above transmitter 4, which can be mounted inside a name tag of commonly used dimensions, is known.

In the figure, reference numeral 6a indicates a wave signal receiving element such as an antenna in the wave signal detector 6, reference numeral 12 indicates a mounting pin, and reference numeral 13 indicates a charging terminal. When not in use, the charging terminal 13 of the name tag 1 is inserted into a charging power outlet (not shown) to charge the power source 5 and store the name tag 1. Preferably power supply 5
The human body-mounted detection sensor mentioned above should not operate while the battery is being charged.

When the name tag 1 is accidentally or intentionally dropped from the human body, the wave signal detector 6 identifies and detects the different wave signals S from the name tag 1 described above, and the wave signal detector 6 The location or the approximate location of the dropped name tag 1 is displayed in a monitoring room (not shown). Further, in response to the display, a security guard or other guard may start searching for the name tag 1, or confirm the name of the person H who should hold the name tag 1 using a register or the like, and then call the person by broadcasting in the building.

The range of the wave signal S from the transmitter 4 is selected to be short, and a large number of wave signal detectors 6 are arranged in the protected area P at appropriate intervals related to the range of the wave signal, and the name tag 1 is attached. If different wave signal detectors 6 are configured to sequentially detect the wave signals S according to the movement of the person H, the movement route of the person H, that is, the conductor can be monitored and recorded as necessary.

Effects of the Invention As explained above, the security device according to the present invention has the following features:
It uses a name tag that has a built-in transmitter and a sensor attached to the human body and is attached to an unqualified person, a detector installed in a protected area that detects the wave signal from the transmitter, and a security switch device that responds to the output of the detector. It has the following effects.

(b) A security switch device can respond appropriately to the signal emitted when a name tag is worn and the different signals emitted when a name tag is dropped, thereby reliably preventing unauthorized persons from entering the protected area.
