Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio alarm device installed near a door where substation equipment, mechanical equipment, etc. are installed.

[0002]

2. Description of the Related Art Along with the enforcement of the PL Law, alarm guidance in use for a user, such as emphasis on a dangerous spot with a label and attention in an instruction manual, is gaining importance. Moreover, as a method, visual means such as labels and instructions are almost being established. In the case of power receiving and substation equipment and various mechanical equipment, in addition to the precautions for those machines, strict attention is required to enter the equipment area, and various measures to ensure safety are required for users and maintenance personnel. Has been requested.

[0003] Conventionally, a label is attached to a danger point,
It emphasizes visual dangers and alerts people who approach the environment. In addition, an instruction manual is attached to the system, and a form in which the contents of the danger are received is adopted.

[0004]

In the prior art, the danger is avoided by visual observation or explanation, but in the conventional method, it is felt that there is a shortage of measures in terms of safety. Therefore, the present invention provides locking of dangerous areas,
To provide a sound alarm device that can more reliably prevent accidents by giving a sound warning in addition to danger indications at danger points, emphasis on strictly adhered to by instruction manuals, education by instructions for use, etc. It is an object.

[0005]

According to a first aspect of the present invention, there is provided an audio alarm device, wherein a door state detecting device for detecting whether a door is locked or unlocked and an object approaching a predetermined range of the door. And a first for determining whether or not the detection content detected by the sensor is within a predetermined set range.
And a second determination circuit for determining whether or not the detection content detected by the door state detection device is within a predetermined setting range, and different attention contents depending on the determination result of the second determination circuit. It is characterized by comprising a plurality of alert issuing circuits for issuing an alert, and a speaker device for alerting the content of the alert by voice.

According to a second aspect of the present invention, there is provided a voice alarm device comprising an electromagnetic wave generator for outputting an electromagnetic wave for inhibiting the use of a PHS or a portable telephone by an output of a caution alarm circuit.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the voice alarm device of the present invention will be described. In FIG. 1, a door state detection device 1 is a device that detects a locked or unlocked state of a door, and a sensor 2 is a detector that detects that an object has approached a predetermined range of the door.

The judgment circuit 4 is a circuit for judging whether or not the content detected by the sensor 2 is within a predetermined set range, and the judgment circuit 5 is a circuit for determining whether the content detected by the door state detection device 1 is predetermined. This is a circuit for determining whether or not it is within a setting range.

The attention issuing circuits 6 and 7 are circuits that issue different attention contents depending on the judgment result of the judgment circuit 5, for example, the attention issuing circuit 6 outputs a guidance of "somewhat dangerous", The caution alerting circuit 7 outputs a guidance of "more dangerous". The loudspeaker device 8 is a device that warns by caution of the contents of caution based on these guidances.

The processing device 3 is constituted by the determination circuits 4 and 5 and the warning notification circuits 6 and 7.

That is, a dangerous place in a building where no one can enter normally, a machine room, a water storage room, and the like can be considered. Here, an electric room will be described as an example. Usually, a danger label is attached to the entrance door of the electric room, and the door is locked, so that approaching people call attention to those who have come to the purpose.

[0012] Here, a human sensor for feeling a person is attached near the entrance of the electric room, and when a person approaches, a danger content at the place is reported by a speaker provided near the person, and the danger currently being carried out. Implement in such a way as to add to the measures.

[0013] Locking and unlocking of the door are also input as one of the conditions, and the guidance contents are used step by step, etc., and also effectively act as a function to call attention.

The voice alarm device according to the second aspect is characterized by comprising an electromagnetic wave generating device 9 for outputting an electromagnetic wave for prohibiting the use of the PHS or the portable telephone by the output of the caution alarming circuit 7.

[0015] A human sensor is provided near a switchboard on which a device that may malfunction due to electromagnetic waves, such as a protective relay or an earth leakage circuit breaker, is installed. This is one of the measures to prevent the use of high-priority facilities and to prevent the impact on highly important facilities.

According to the above configuration and operation, the present invention can be implemented at a relatively low cost with respect to the existing equipment, and a large one can be obtained effectively.

[0017]

According to the present invention, the operational safety of the voice alarm device can be improved.
