BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body detector for detecting a human body by detecting infrared rays emitted from the human body, and more particularly to a device for outputting a voice message from a built-in speaker according to a human body detection signal. More specifically, the present invention relates to a human body detector with a voice message function that is connected to a mechanical security device that installs various sensors on a security target and monitors at a remote monitoring center and outputs a voice message corresponding to a security status. is there.

2. Description of the Related Art Conventionally, various types of human body detectors have been used in various fields as human body detectors for detecting a human body by receiving infrared radiation, which is radiant energy generated by the human body. Above all, it is known to be installed near the entrance of a store and to output a voice message from a built-in speaker when a human body is detected. It is provided to know the entrance and exit quickly.

Such a human body detector includes a human body detection section that receives infrared rays emitted from the human body and outputs a human body detection signal, a voice synthesis circuit that outputs a built-in voice message using the human body detection signal as a trigger, and an amplifier. And a speaker. There is also known another human body detector with a voice message function that is installed at an entrance and exit, detects the traveling direction of a customer, and sends a message corresponding to the traveling direction.

[0004]

On the other hand, a human body detector using infrared rays is often used for mechanical security. In general, a mechanical security device is provided with a mechanical security device in which various detectors are connected to a security target, and an alarm or the like generated by the detector is monitored at a remote monitoring center via communication means. However, the conventional human body detector with a voice message function is mainly set to be used by store operators for store operation, and does not have a sufficient function for use as a human body detector for machine security. This is because the voice message function is set to operate uniformly even when the power is turned on.

That is, in the case of mechanical security, security is unmanned and security is unmanned, and when the setting is changed (when security is released and security is started), the operation mode must be changed. For example, it is necessary not to output a voice message during security release, to output a voice message corresponding to the start state when security is started, and to output a voice message corresponding to the release state when security is released. Therefore, the conventional human body detector with a voice message function cannot be used for this purpose.

The present invention has been made in order to solve the above-described problems, and can output voice messages corresponding to each situation at the time of starting security and at the time of releasing security, and can provide a mechanical security device. It is an object of the present invention to obtain a human body detector with a voice message function that can reliably perform the operation of the machine and smoothly operate the mechanical security.

[0007]

The human body detector with a voice message function according to the present invention is turned on when a security start signal is input from a mechanical security device and turned off when a security release signal is input. A first voice synthesis circuit for synthesizing and outputting a first voice message, a second voice synthesis circuit for synthesizing and outputting a second voice message, and a first voice synthesis circuit when the input circuit is turned on from off. A voice synthesizer is operated to output a first voice message for a predetermined time, and when a human body detection signal is input while the input circuit is turned on, a second voice synthesizer is operated for a predetermined time to generate a second voice message. A selection circuit that outputs a message, an amplifier that is turned on during the security period and amplifies the selected voice message,
A speaker for outputting the output of the amplifier as audio is provided.

[0008]

In the present invention, when a security start signal is input from the mechanical security device, the input circuit is turned on and the amplifier is turned on, and the first voice message is output from the first voice synthesis circuit for a predetermined time. The signal is amplified by the amplifier and output as sound from the speaker. When a human body detection signal is input with the input circuit turned on, a second voice message is output from the second voice synthesis circuit for a predetermined time, amplified by an amplifier, and output as voice from a speaker.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a human body detector with a voice message function according to this embodiment, wherein 1 is a human body detection unit that detects infrared rays emitted from a human body and outputs a human body detection signal, and 2 is a security guard from a mechanical security device (not shown). An input circuit for inputting a mode setting signal, 3 is a timer circuit, 4 is an amplifier, 5 is a first speech synthesis circuit, 6 is a second speech synthesis circuit, and 7 is a first speech synthesis circuit.
And a selection circuit for selecting the second speech synthesis circuits 5 and 6,
Is a speaker.

As shown in FIG. 3, the human body detector A with a voice message function having the above-described configuration is installed near an entrance (final exit) of a security target to be subjected to mechanical security, and is connected to a mechanical security device (not shown). You. The dotted line indicates a detection area where a person passing through the entrance can be detected. B is a door opening / closing detector for detecting opening / closing of the door 9 of the entrance, and is connected to a mechanical security device (not shown).

Next, the operation of the above-described human body detector with a voice message function will be described with reference to the time chart of FIG. Now, assuming that the mechanical security device is in the security release state, the mechanical security device does not transmit a security start signal, the input circuit 2 is off, and the amplifier 4 is not operating. Therefore, in this security released state, no voice message is output from the speaker 8 even if the human body detector 1 detects a human in the detection area of the entrance shown in FIG. 3 and generates a human body detection signal.

Here, if the last exiting person from the entrance opens the security switch by operating the operation switch of the mechanical security device, the mechanical security device does not immediately start guarding, but for a predetermined time, for example, the last exiting person enters the security entrance. Even if the detection signal is received from the door opening / closing detector B for a time sufficient to lock the door and leave the security object, the alarm signal is not output to the remote monitoring center. The set time T of the timer circuit 3 is set to be equal to or slightly shorter than a predetermined time after the above-described security start operation of the mechanical security device.

The input circuit 2 is turned on when a security start signal is input from the mechanical security device, and activates the amplifier 4 and the timer circuit 3. Selection circuit 7
, The input circuit 2 is turned on, the timer circuit 3 activates the first voice synthesis circuit 5 only during the operation of the time T, and the first voice synthesis circuit 5 outputs a first voice message stored in advance. . This message should prompt you to leave, for example, "I'm just starting security now. Please leave now."

The first voice message is output from the speaker 8 via the amplifier 4, and is repeatedly output while the timer circuit 3 is operating. The final exit person hears the first voice message, confirms that security has been started, and immediately exits the security target. During this time, even if the human body detection signal is output from the human body detection unit, it has nothing to do with the operation. When the timer circuit 3 times out after the set time T has elapsed, the selection circuit 7 stops the operation of the first speech synthesis circuit 5.

Next, in the security state of the mechanical security device,
When a person enters the detection area of the entrance, the human body detection unit 1 outputs a human body detection signal. In this case, even if the mechanical security device receives the detection signal of the door opening / closing detector B, it does not immediately output an alarm to the monitoring center. That is, if the security is released by operating the operation switch within the predetermined time, no alarm is output.

When the input circuit 2 is turned on and the human body detection signal is received, the timer circuit 3 starts a timer operation for a predetermined time T. At the same time, the selection circuit 7 activates the second speech synthesis circuit 6 for the time T, and the second speech synthesis circuit 6 synthesizes and outputs a second speech message stored in advance. Second
The voice message of urges the security to be released, for example, "We are currently guarding. Please release immediately." The second voice message is output from the speaker 8 via the amplifier 4 and repeatedly output while the timer circuit 3 is operating.

If the person entering through the entrance is a regular person to be guarded, the second voice message is heard and the operation switch of the mechanical security device is released, so that no alarm is output. When the timer circuit 3 times out, the selection circuit 7 stops the operation of the second speech synthesis circuit 6.
When the security device is released from the security, the input circuit 2 is activated.
, A security release signal is input, and the input circuit 2 is turned off.
Since the amplifier 4 is also turned off, no message is output.

In the above embodiment, the human body detection signal from the human body detection section 1 is not output to the mechanical security device, but the human body detection signal is output to the mechanical security device so that May be used in place of the door opening / closing detector B provided in the above.

[0019]

[Effect of the invention] As described above, according to the invention, according to the respective situations at the time of security start and at the time of security release of the security target.
Ru can be output a different voice message. to this
More confused by those unfamiliar with the operation of mechanical security devices
The security guard can be started and released automatically by the mechanical security device , so that people who enter and exit
Rutotomoni can be sure that it has been reliably performed, for unauthorized intruders can be obtained threatening effects. Also, since only the human body detection function at the security entrance is required, there is no need for a wide detection area like a commonly used security intruder detector, and the optical system for infrared detection elements can be simplified. Inexpensive configuration can be achieved. Furthermore, since the security start signal of the mechanical security device can be used as soon as it can be input, it can be easily added to a security target that has already introduced mechanical security. From these facts, the operation of mechanical security can be performed smoothly.
