Description

technical field [0001] The invention belongs to the technical field of gas engine safety monitoring, and in particular relates to an intelligent safety monitoring system for gas engine units based on ZYNQ7020. Background technique [0002] With the continuous development of economy and technology, gas has become an indispensable part of people's daily life because of its convenience and environmental protection. With the widespread use of gas, the safety of gas-fired units has become the focus of people's increasing attention, especially the potential safety hazards caused by gas leakage in gas-fired units are the most prominent. Therefore, people install gas monitoring at locations where gas leakage is likely to occur At present, several gas monitoring devices on the market mainly have the following problems: [0003] (1) At present, gas leakage is most likely to occur at the connection between the flange and the pipeline of SPIC's gas-fired unit. However, due to the high ...

AI Technical Summary

Problems solved by technology

[0003] (1) At present, gas leakage is most likely to occur at the connection between the flange and the pipeline of SPIC's gas-fired unit. However, due to the high temperature near the leakage of the compressor extraction pipeline and the natural gas pipeline, most of the gas leakage detection devices are active devices. Susceptible to explosion damage in high temperature environments

[0004] (2) At present, most gas-fired units still use manual hand-held thermometers to point to the leak-prone point to display the temperature of the area to judge whether there is a leak. This inspection mode relies too much on the subjective initiative of the human body. If leakage occurs from time to time, it is difficult to judge and alarm at the first time. If leakage occurs outside the experience area, it will be more difficult to be discovered in time, and the risk of false alarm is prone to occur.

[0005] (3) Since the gas pipeline is equipped with a self-closing valve, the self-closing valve will automatically close when the gas supply pressure of the pipeline is under-pressure or over-pressure. Underreporting

[0006] (4) Some gas monitoring devices have the functions of timing switch valves, detecting ambient temperature and gas leakage, but the actuator and the controller use wired communication, which is inconvenient for construction and installation, and it is also impossible to accurately locate the location and degree of gas leakage. In addition, it is difficult to push monitoring information to users in real time
