Abstract

The invention discloses a wireless gas pressure monitoring system which comprises a device body, a membrane, at least two reflecting mirrors, an infrared transmitter, photosensitive sensors and a single chip microcomputer. The internal space of the device body is divided into two gas chambers by a membrane, one gas chamber is connected with a gas pipeline to be monitored, the other gas chamber isa sealed gas chamber with standard atmospheric pressure, the infrared transmitter is used for providing an infrared light source, and the membrane is made of a pressure deformation material and can deform according to the different gas pressure values of both sides of the membrane and protrude toward the gas chamber with a smaller gas pressure value. The reflecting mirrors are connected to the membrane and are arranged in the horizontal direction and oppositely staggered in position, and the infrared light source is reflected by the reflecting mirror and is transmitted to the photosensitive sensor; multiple photosensitive sensors are densely distributed in the horizontal direction, the photosensitive sensors are connected with the single chip microcomputer; the single chip integrates witha wireless transmission module which can transmit detection data to a terminal through wireless signals.

Description

technical field [0001] The invention relates to a wireless gas pressure monitoring system, in particular to a high-sensitivity wireless gas pressure monitoring system, which belongs to the technical field of power system applications. Background technique [0002] The gas pressure sensor at this stage is mainly based on the piezoresistive sensor. By setting up two gas chambers (one connected to the gas pipeline to be measured, and one sealed standard atmospheric pressure chamber, separated by a concave-convex diaphragm in the middle), the diaphragm and the piezoresistive sensor A spring is connected between them, and the force of the gas on both sides of the diaphragm acts on the sensor through the spring, so as to reflect the pressure of the gas to be measured. [0003] Although there are various types of gas pressure sensors, there is still a lack of a wireless gas pressure monitoring system with high sensitivity, wireless transmission, and real-time online monitoring of p...
