Description

A kind of remote-adjust method and mining intelligent methane warning miner's lamp

Technical field: the present invention relates to a kind of remote-adjust method and mining intelligent methane warning miner's lamp.

Background technology: application number 85203013 has been announced a kind of gas warning head lamp, is to be convenient to illumination and the dual-purpose lamp of gas alarming that the personnel in the pit carries, and is made up of lamp holder, cable and accumulator box.The sensor that Xe lamp bulb is housed on the lamp holder and makes by heat catalytic element.What link lamp holder and accumulator box is the cable that six roots of sensation conductive core line is formed, and control circuit board is contained in above the battery case, and this lamp is used for illumination when gas density does not transfinite.When gas density transfinites, can control the bulb flashing light alarm.Application number: 90202528.7 have announced the automatic warning miner's lamp of a kind of gas.Form by electric insulation housing and the testing circuit, amplifying circuit, delay circuit, oscillatory circuit, NAND gate circuit, light warning circuit and the mu balanced circuit that are installed in the housing.It converts electric signal to after being detected airborne flammable explosive gas (Device in Gas) by the test section, reaches the warning purpose by after above-mentioned each circuit function with the bright dark variation of light.But have the problem of methane gas concentration calibration difficulty and device adjustment difficulty, the layman is difficult to grasp, and precision and stability do not reach required standard, usually produce to report by mistake and fail to report.And the equipment worn when going into the well of coal miner is many and weigh, and alleviates workman's burden, with methane detection alarming instrument with mine lamp is combined and two be one also to be workman's demand.Because underground work condition flag, the workman likes moving back and forth instrument, any button click makes the instrument cisco unity malfunction, and the mining intelligent methane warning miner's lamp with remote-adjust function makes the mining methane warning miner's lamp of adjustment more convenient reliably accurately, not fragile.

Summary of the invention: the objective of the invention is to improve the shortcoming of prior art, a kind of remote-adjust method and mining intelligent methane warning miner's lamp are provided.For achieving the above object, the present invention takes following design proposal: mining intelligent methane warning miner's lamp of the present invention is by battery case, cable, lamp holder, switch, alarm indication plate and sensing element cavity are formed, in the alarm indication plate wiring board is arranged, wiring board is furnished with control circuit, control circuit is by the circuit working state display circuit, the circuit working state display circuit has charactron, the comparison operation amplifying circuit, Wheatstone bridge circuit, the singlechip CPU microprocessor, sound light alarming circuit and memory storaging chip, sound light alarming circuit has buzzer circuit, remote-control receiving circuit, conversion function key, clock chip, carrier catalyst element are connected on the brachium pontis of Wheatstone bridge circuit.The singlechip CPU microprocessor connects duty display circuit, memory storaging chip.

Mining intelligent methane warning miner's lamp adjusting process of the present invention:

Step 1 is opened on ﹠ off switch, and power turn-on circuit, is used for change over clock and methane numerical value and shows that each road signal circuit state is checked in the operation of singlechip CPU microprocessor software the handoff functionality key;

Step 2, the crawl remote controller key increases key: under methane numerical value show state by once showing cell voltage E.XXX enters alarming value the apparent H of state is set as continuing in 2 seconds by for the second time.H flicker after XXX2 kind second.This moment, available increase key and minimizing key were finished the alarming value setting, had established six alarming values (0.5,0.75,1,1.5,2,2.5), were located at 1.0% and reported to the police, and set the back by acknowledgement key;

Step 3 reduces key: under the methane show state, and by once returning to zero for instrument software, first 0 of LED, 0.25.Be set in 0.25 scope (setting of machine inner potential device), as be presented at 0.01～0.5 and can return to zero, but less than 0.2, greater than all must carrying out calibration again after the zeroing of 0.3 software, otherwise influence accuracy of instrument with software.

Step 4, press secondary for demarcating, when instrument under the methane state, reduce key by secondary, first charactron shows little C, and back three show 0.00, C begins flicker after two seconds kinds, fill 1% above methane calibrating gas, flow p.s. 200ml with increasing key or reduce key, displayed value be transferred to charge into calibrating gas numerical value when identical by definite key;

Step 5 is determined key: determine key once as pressing under the clock show state, hour adjustment ^-Be provided with hour with increasing and reducing, after treating hour setting, by for the second time,-0.00 usefulness minute is set to be increased and reduces key setting, set up the back by for the third time _ second setting, after being provided with, when pressing for the 4th time, just now the clock that was provided with and revised shows that at once clock, promptly shows after the kind self check in 5 seconds of starting shooting because replacing battery and fault need not be adjusted eternal maintenance as not being.

The present invention combines methane detection alarming instrument and mine lamp, reduces workman's burden.Avoid the random button click of workman, make the instrument cisco unity malfunction, the mining methane warning miner's lamp with remote-adjust function makes the mining methane warning miner's lamp of adjustment more convenient reliably accurately, not fragile.Have methane gas concentration calibration, convenient, the simple advantage of adjusting process, the layman grasps easily, the shortcoming and the artificial instrument state of manually intervening of prior art potentiometer method of adjustment have been overcome, instrument and people's man-machine interface is first (zone bit) that telepilot and charactron show, telepilot is convenient to management, the wearer can't change the various state settings of instrument, guarantees accuracy of instrument and stability.
