Abstract
The utility model relates to a gas transmitter, which comprises an outer shell, a detection probe and a treatment circuit, wherein the outer shell has one end provided with an aircraft plug, and a power input end and a detection digital signal communication end of the treatment circuit are connected with connection terminals in the aircraft plug respectively. When the gas transmitter of the utility model is applied to a catalytic type gas transducer, and when the gas transmitter needs to be periodically adjusted, a gas transmitter well adjusted can directly replace the gas transmitter on the gas transducer, which needs to be adjusted, and the plug-and-play is realized due to the adoption of the aircraft plug, so that the adjustment work is convenient, and the cost is relatively low; in addition, when the service life of the gas transmitter almost expires, the gas transmitter can be directly replaced by a new gas transmitter, and other parts of the transducer are not changed, thereby avoiding the replacement of the whole transducer in prior art and further saving costs and resources.
Description
Technical field
The utility model relates to a kind of gas detecting device, is specifically related to a kind of gas transmitter.
Background technology
Must regularly carry out adjustment when the catalysis type firedamp sensor of existing fixed in the down-hole uses at present, existing adjusting process mainly contains two kinds, a kind ofly be: firedamp sensor that will adjustment is good is directly replaced out the firedamp sensor that adjustment is treated in the down-hole, aboveground the firedamp sensor of replacing out is carried out adjustment then, and as replacing next time, though this method is easy, the cost of early investment is higher; Another kind is: be with standard gas sample to go into the well by the adjustment personnel each firedamp sensor is carried out adjustment one by one, this method wastes time and energy, and standard gas sample cost is higher; In addition, because the catalysis detecting element of catalysis type firedamp sensor is easily to consume element, be 1-2 its serviceable life, so the catalysis detecting element expires and must change.In the prior art, mode for fixedly being electrically connected between the testing circuit of catalysis detecting element and firedamp sensor, it is inconvenient to dismantle, so the appointed date often can only scrap whole firedamp sensor, cause the waste of resource, increased the maintenance and the use cost of gas safety detection system.
The utility model content
Technical problem to be solved in the utility model provides a kind of adjustment work that both can make things convenient for firedamp sensor, can be convenient to the gas transmitter that separates and install with firedamp sensor again.
For solving the problems of the technologies described above, the utility model provides a kind of gas transmitter, comprising: shell, be located at detection probe and the treatment circuit that links to each other with detection probe in the shell; One end of shell is provided with aviation plug, the power input of treatment circuit with detect the digital signal communication terminal and link to each other with connection terminal in this aviation plug respectively.
In the technique scheme, the detection digital signal communication terminal of described treatment circuit adopts the SMBUS bus.
In the technique scheme, described treatment circuit comprises electric bridge, the signal amplification circuit that links to each other with electric bridge, analog to digital conversion circuit that links to each other with the signal output part of signal amplification circuit and the single-chip microcomputer that links to each other with the digital signal output end of analog to digital conversion circuit, and the signal output part of this single-chip microcomputer is the detection digital signal communication terminal that adopts the SMBUS bus.
The utlity model has positive effect: (1) gas transmitter applications of the present utility model is behind the catalysis type firedamp sensor, when regularly the gas transmitter being carried out adjustment, gas transmitter that can adjustment is good is directly replaced the gas transmitter for the treatment of adjustment, because aviation plug can be realized plug and play, therefore made things convenient for adjustment work, and cost is lower.In addition, when the gas transmitter closes at the expiration serviceable life, can directly replace with new gas transmitter, the remaining part of sensor is not changed, and has avoided directly scrapping in the prior art situation of whole sensor, has both saved cost, has saved resource again.(2) gas transmitter of the present utility model adopts the SMBUS bus signals to transmit, compatible I2C bus signals, and CRC check mechanism is adopted in the signal transmission, and it is strong to have an antijamming capability, has eliminated problems such as the gas concentration transmission is inaccurate.(3) to the regular adjustment of firedamp sensor the time, because gas transmitter of the present utility model is more much lower than the cost of gas transmitter of the prior art, so can directly new firedamp sensor be replaced out the old firedamp sensor in down-hole, then that these are old firedamp sensor is taken well and is carried out adjustment, deposits the warehouse after adjustment is finished in and as the substitute of next adjustment; Therefore, adopt gas transmitter of the present utility model can reduce the maintenance and the use cost of existing gas transmitter, and improve adjustment efficient.

Embodiment
(embodiment 1)
See Fig. 1-2, the gas transmitter of present embodiment comprises: shell 1, be located at detection probe 3 and the treatment circuit 4 that links to each other with detection probe 3 in the shell 1; One end of shell is provided with aviation plug 2, the power input of treatment circuit 4 with detect the digital signal communication terminal and link to each other with connection terminal in this aviation plug respectively.
The detection digital signal communication terminal of described treatment circuit 4 adopts the SMBUS bus.
Described treatment circuit 4 comprises electric bridge, the signal amplification circuit that links to each other with electric bridge, analog to digital conversion circuit that links to each other with the signal output part of signal amplification circuit and the single-chip microcomputer that links to each other with the digital signal output end of analog to digital conversion circuit, and the signal output part of this single-chip microcomputer is the detection digital signal communication terminal that adopts the SMBUS bus.
The gas transmitter applications of present embodiment is when the catalysis type firedamp sensor, and the gas transmitter is the catalysis detecting element, and the detection signal input end in itself and the firedamp sensor is by the aviation plug socket connection.When regularly the gas transmitter being carried out adjustment, gas transmitter that can adjustment is good is directly replaced the gas transmitter for the treatment of adjustment on firedamp sensor, therefore is convenient to adjustment work.Adopt aviation plug can realize plug and play, easy to use.
When the gas transmitter closes at the expiration serviceable life, can directly replace, avoid in the prior art the directly situation of replacement whole sensor, both save cost, save resource again with the gas transmitter of new present embodiment.
See Fig. 3, the gas transmitter applications of present embodiment is under coal mine during locomotive monitoring system, the locomotive monitor main frame is gathered the gas concentration that the gas transmitters sense arrives by the SMBUS bus, then described gas concentration is uploaded to the locomotive display device by the RS232/RS485 bus and shows.The gas transmitter of present embodiment has uses simply advantage easy to maintenance.
When adjustment gas transmitter, school gas transmitter is adjusted and is revised its inner parameter by the adjustment frock, and the adjustment frock is carried out data presentation by charactron, and whole adjustment process can be finished by external remote.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
