Abstract

The invention discloses an embedded catalytic luminescence image sensing device for remotely monitoring sulfur hexafluoride in real time. The embedded catalytic luminescence image sensing device comprises a gas inlet, a peristaltic pump, a temperature controller, a glass pipe, an image acquiring and processing module, a ventilation guide pipe, a sensor array, a catalytic material, a waste gas exhaust outlet, an Oracle database, an ARM [advanced RISC (reduced instruction set computer) machine] board card, a data transmission module, wireless communication and an upper computer. The catalytic material for sensor array units comprises SnO2, Fe2O3, La2O3 and ZnO. The image acquiring and processing module is used for acquiring sensing array images generated by means of catalytic luminescence; the ARM board card is used for controlling operational parameters of the peristaltic pump, the temperature controller and the image acquiring and processing module in a centralized manner and transmitting acquired sensing data information to the upper computer by the aid of the data transmission module. The embedded catalytic luminescence image sensing device has the advantages that sulfur hexafluoride catalytic luminescence sensing images can be acquired in real time, data can be wirelessly transmitted, and the embedded catalytic luminescence image sensing device is short in sensing response time, long in transmission distance and high in anti-interference capacity.

Description

technical field [0001] The invention relates to a model for monitoring sulfur hexafluoride by using the principle of catalytic luminescence, in particular to an embedded device for remote real-time monitoring. Background technique [0002] In the field of power engineering, sulfur hexafluoride is usually used as the electronegative gas. Because sulfur hexafluoride gas has good insulation and arc extinguishing properties, it is mainly used in the following electrical equipment: sulfur hexafluoride circuit breakers, sulfur hexafluoride load switchgear, sulfur hexafluoride insulated transmission pipelines and hexafluoride High-voltage power devices such as sulfur-insulated substation transformers. High-purity sulfur hexafluoride is an important electronic etchant and has been widely used in microelectronics technology. When sulfur hexafluoride gas is injected into the high-voltage switchgear, a certain pressure will occur, which increases the possibility of gas leakage. This ...
