Abstract

The invention discloses a self-inductive acousto-optic warning sign which consists of a shell and a built-in circuit. The built-in circuit comprises a power source, a power switch, a sensitivity adjusting switch, an infrared inductive probe, a red warning light, a loudspeaker, an infrared inductive module and a voice integrated module. The connection relation of the circuit is based on component specifications. The built-in circuit is installed inside the shell, the infrared inductive probe and the red warning light are installed at the front side of the shell, and round bottom corner fixing magnets are respectively installed at all corners of the backside of the shell. The warning sign is not limited by environment and light and can be conveniently attached on an iron power distribution switch cabinet. The self-inductive acousto-optic warning sign is a piece of optimal equipment for safety warning in electric power overhaul.

Description

The self-induction acoustic-optic warning board

Technical field

The present invention relates to a kind of servicing unit of electric power overhaul operation, relate in particular to a kind of self-induction acoustic-optic warning board that automatically sends alarm function that has.

Background technology

At present, in electric power overhaul work, if in the place's operation of 10-35kV switch cubicle, normally one section bus has a power failure, and one section bus is charged, or power failure of breaker, and the bus bar side disconnecting link is charged, and the security control measure that take at the scene is that " halt, Keep Clear-High Voltage in placement! " nameplate, warning lamp and establish special messenger monitoring; Above-mentioned safety practice in use has limitation: the first, and the operations staff need arrange that twice safety practice is the measure control that " listing ", " putting lamp " just can be finished nearly electric dangerous point; The second because human eye is not strong to " halt, Keep Clear-High Voltage board " and the sense organ sensitivity of warning lamp color, be difficult for causing that the maintainer notes, particularly " halt, Keep Clear-High Voltage board " result of use is poorer under dim environment; The 3rd, (as back to closing on the work of charged position) lacks personnel near the automatic-prompting at charged position in the time of can not observing " halt, Keep Clear-High Voltage board " and warning lamp in the maintainer works the visual field, can only rely on to specialize in the guardian and remind monitoring.

The present invention combines the caution content of above-mentioned safety practice, adopts the self-induction acoustic-optic warning board that has acousto-optic and use automatic alarming function, sends sound and light alarm to the personnel near the forbidden zone.

Summary of the invention

The objective of the invention is behind the safety zone of determining interruption maintenance, provide a kind of when personnel distinguish near danger, can automatically send the device of sound and light alarm.

For reaching above-mentioned purpose, the technical scheme that the present invention takes is: a kind of self-induction acoustic-optic warning board, it is comprised of housing and built-in circuit two parts, and built-in circuit comprises power supply, power switch, sensitivity switch, infrared induction probe, red warning lamp, loudspeaker, infrared induction module and voice integration module; The annexation of its circuit is: "+" end of power supply connects respectively power supply input "+" terminal of infrared induction module and voice integration module behind power switch K1, connects the negative pole of power supply after its "-" terminal parallel connection; The sensitivity switch of warning sign connects TP2, the TP3 terminal of infrared induction module, and the infrared induction probe connects TP4, TP5 terminal, and red warning lamp connects TP7, TP8 terminal, and the KS2 of voice integration module, KS3 terminal connect loudspeaker; Enclosure interior at device is installed built-in circuit, the front installation infrared inductive probe of housing, red warning lamp, and a circular base angle fixed magnet is installed in each bight, the back side of housing.

The infrared induction probe of self-induction acoustic-optic warning board is installed in the front center of housing, apart from 10～15mm position, both sides red warning lamp is installed in the lower right corner; Power switch is installed at upper right 1/3 position of housing, and sensitivity switch is installed apart from frame 10～15mm position in its left side; Power supply is installed at 10～15mm position under the back side of shell center line, and loudspeaker is installed apart from minor face 30mm, 15mm position, long limit in the lower left corner.

Because this warning sign is not subjected to the impact of environment, light, can paste easily and be placed on the irony panel switches cashier's office in a shop, be the preferred equipment of electric power overhaul security warning.

Concrete embodiment

Below in conjunction with accompanying drawing circuit of the present invention, structure are described in further detail:

Such as Fig. 1, Fig. 2 as can be known, the self-induction acoustic-optic warning board is comprised of housing and built-in circuit two parts, and built-in circuit comprises power supply 1, power switch 2, sensitivity switch 3, infrared induction probe 4, red warning lamp 5, loudspeaker 6, infrared induction module and voice integration module; The annexation of circuit is in the device: "+" end of power supply 1 is connected to respectively power supply input "+" terminal of infrared induction module and voice integration module behind power switch K1, connect the negative pole of power supply 1 after its "-" terminal parallel connection, power supply 1 can be selected battery No. 5, infrared induction module model is GH-718, voice integration module model is XF-S4240, or universal module; The sensitivity switch 3 of warning sign connects TP2, the TP3 terminal of infrared induction module, and sensitivity switch 3 can be selected the switch that is made of adjustable resistance commonly used; Infrared induction probe 4 connects TP4, TP5 terminal, and red warning lamp 5 connects TP7, TP8 terminal, and the KS2 of voice integration module, KS3 terminal connect loudspeaker 6, and above-mentioned probe, lamp and loudspeaker all select the general-purpose device in the electronic devices and components.

By Fig. 2, Fig. 3 as seen, at the inner built-in circuit of installing of device case, the front installation infrared inductive probe 4 of housing, red warning lamp 5, a circular base angle fixed magnet 7 is installed in each bight, the back side of housing.

As seen from Figure 2, the infrared induction of warning sign probe 4 is installed in the front center of housing, apart from 10～15mm position, both sides red warning lamp 5 is installed in the lower right corner.
