Abstract
The utility model discloses a kind of mine curve alarm device based on PIC12F675 chip, relate to mine curve technical field.This utility model has a PIC12F675 chip；Described PIC12F675 chip connects to be had for detecting the signal input module of bend locomotive arrival signal, voice broadcast module and power module；The input of power module connects power supply, and power module output 5.5V DC voltage is to PIC12F675 chip power supply.Due under the prompting having security warning voice broadcast, at the coal miner of bend operation, the very first time can obtain locomotive by the operation information of bend, thus will enhance your vigilance, and protects self so that the accident rate of colliery bend is substantially reduced.
Description
Technical field
This utility model relates to mine curve technical field, a kind of mine curve based on PIC12F675 chip
Alarm device.
Background technology
Coal mine locomotives has personnel to collide injured, material through bend to knock accident over and occur, be underground work person mostly often
Work is held inaccurate for locomotive by the time of bend, embraces lucky at heart across bend, rushes to transport material, cause injury to personnel, thing
Expect that impaired accident occurs, this effectively prevented the generation of bend shipping accident have for realizing mine safety life production
Highly important realistic meaning.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, this utility model provides a kind of based on PIC12F675 chip mining
Bend alarm device, signal on the horizon to bend locomotive detects, and when signal being detected, carries out high-decibel immediately
Voice security warning forecasts.
This utility model realizes with following technical scheme: a kind of mine curve based on PIC12F675 chip is reported to the police
Device, including PIC12F675 chip；Described PIC12F675 chip connects the letter for detecting bend locomotive arrival signal
Number input module, voice broadcast module and power module；The input of power module connects power supply, power module output 5.5V
DC voltage is to PIC12F675 chip power supply.
Preferably, described power supply uses 12V intrinsically safe power supply.
Preferably, described signal input module uses proximity switch, and proximity switch hangs on the wall near bend
The top, tunnel of upper or close bend.
The beneficial effects of the utility model are: due under the prompting having security warning voice broadcast, in bend operation
Coal miner, the very first time can obtain locomotive by the operation information of bend, thus will enhance your vigilance, and protects self so that
The accident rate of colliery bend is substantially reduced.
Accompanying drawing explanation
Fig. 1 is this utility model theory diagram.
Detailed description of the invention
As it is shown in figure 1, a kind of mine curve alarm device based on PIC12F675 chip has a PIC12F675 chip；Institute
The chip stated connects to be had for detecting the signal input module of bend locomotive arrival signal, voice broadcast module and power supply mould
Block；The input of power module connects power supply, and power module output 5.5V DC voltage is to PIC12F675 chip power supply.
In the present embodiment, signal input module uses proximity switch, and proximity switch hangs in the wall of bend
Or the top, tunnel near bend.
Power supply uses 12V intrinsically safe power supply to provide 12V DC voltage, and 12V intrinsically safe power supply is through power supply mould
Block is converted to 5V DC voltage, and to PIC12F675 chip power supply, 5V positive pole connects 1 foot of PIC12F675 chip, and 5V negative pole connects
8 feet of PIC12F675 chip；Proximity switch connect PIC12F675 chip 2 feet；When locomotive is near bend, proximity switch
Closing, audio alert, after the signal of proximity switch being detected, is triggered signal by 5 feet and reaches voice by PIC12F675 chip
Reporting module, voice broadcast module carries out the voice alarm prompting of high-decibel then.
Claims (2)
1. a mine curve alarm device based on PIC12F675 chip, it is characterised in that: include PIC12F675 chip；Institute
