Technical field
The utility model relates to a kind of miniaturized electronics, particularly relates to a kind of acetylene gas leakage detector.
Background technology
Acetylene gas is a kind of inflammable gas, if there is leakage can cause the danger such as blast.At present the Leak Detection of acetylene gas storage tank is come primarily of manual operation detecting instrument, whether this mode can only to having acetylene gas leakage to carry out periodic detection, and the real-time detection that cannot realize acetylene gas storage tank, simultaneously, more existing acetylene gas leakage detection equipments, usually can only be arranged on body of wall, therefore distance acetylene gas storage tank has certain distance, will cause acetylene gas Concentration Testing inaccurate like this, cannot the leakage of Timeliness coverage acetylene gas.
Utility model content
The purpose of this utility model: provide a kind of acetylene gas leakage detector, directly can be adsorbed on acetylene gas storage tank valve port place, realizes the real-time detection of leaking acetylene gas.
To achieve these goals, the technical solution of the utility model is:
A kind of acetylene gas leakage detector, comprise a cupule head, described cupule head is fixed with vacuum cups, described cupule head inside comprises a small-sized testing circuit, described small-sized testing circuit is integrated with infrared type acetylene inductor, signal changing-over circuit, digital signal converter, Soc integrated manipulator and dryness battery, described infrared type acetylene inductor is connected with described signal changing-over circuit, described signal changing-over circuit is connected with described digital signal converter, described digital signal converter is connected with described Soc integrated manipulator, described Soc integrated manipulator is connected with described dryness battery.
Described infrared type acetylene inductor employs the infrared acetylene sensor IR604 of SGX company of Britain, and described infrared acetylene sensor IR604 have employed the 4-20mA current signal output interface of standard stabiliser.
Described digital signal converter have employed the high speed analog-to-digital conversion chip AD9650-105 of 16 bit resolution precision.
Described Soc integrated manipulator inside includes GPRS signal wireless transmitter and miniature control circuit, described GPRS signal wireless transmitter inside have employed Huawei Company GPRS chip GTM900-C, and described miniature control circuit adopts low power consumption control chip ML620Q503.
The utility model can be adsorbed on the valve port place of acetylene gas storage tank, by detecting corresponding acetylene gas concentration values thus determining whether storage tank there occurs acetylene gas and leak, and be wirelessly transmitted on remote-end alarm equipment by acetylene gas concentration values by long-range GPRS network by Soc integrated manipulator, thus realize the remote monitoring to acetylene gas leakage situation.The utility model adopts small size design, lightweight, can adsorb simply and easily and be arranged in acetylene gas storage tank.
