A kind of warning end of electric power safety prior-warning device, including control section, audio alert part and light alarm part, institute
The control section stated is single-chip microcomputer, and described audio alert part includes loudspeaker, speech chip and level shifting circuit, described
Light alarm part include feux rouges warning circuit, gold-tinted warning circuit and green glow warning circuit, described loudspeaker is connected to language
On sound chip, described speech chip is connected by level shifting circuit with single-chip microcomputer, described feux rouges warning circuit, gold-tinted report
Alert circuit and green glow warning circuit are connected with single-chip microcomputer respectively.
The alarm signal that the utility model sends according to test side, by Single-chip Controlling audio alert part and light report
Alert part, audio alert part reaches speech chip, language chip control after the signal of single-chip microcomputer is changed by level shifting circuit
Loudspeaker processed reports corresponding voice, and light alarm part is gated the optical alarm circuit of certain color by single-chip microcomputer, carried out not equal
The alarm of level.
Described speech chip selects WT2003M02 chips, and different voices are reported for controlling loudspeaker, described to raise one's voice
Device is connected to SPK+ and SPK- pins, and VDD50 pins connect+5V voltages, while constituting mu balanced circuit, DATA by electric capacity earth
Pin receives the data that single-chip microcomputer is transmitted, and BUSY pins send broadcast state.
There are three kinds of optical alarm circuits of color described light alarm part, and feux rouges, gold-tinted, green glow correspond to one-level, two respectively
Level, three-level alarm, by the on-state of Single-chip Controlling warning circuit.
The beneficial effects of the utility model are：
1）The alarm signal that the utility model acquisition testing end sends, carries out corresponding sound and light alarm, is easy to warning
Whether staff enters danger zone, used as a safety guarantee of power construction；
2）The utility model design is simple, rational in infrastructure, can accurately realize different grades of sound and light alarm, and into
This is cheap.
Brief description of the drawings
Fig. 1 is structural principle block diagram of the present utility model.
