Development of multi gas sensor in distribution room based on MEMS and advanced spectrum technology

There are some disadvantages of traditional gas sensor used in power distribution room, such as low integration, high power consumption, low life and information barrier. Thus, STM32L151RDT6 as the main control chip of a multi gas sensor is designed. The gas detection modules of the sensor are encapsulated in MEMS, to monitor multi-group gases – O

) simultaneously by using the optical detection technology and the electrochemical technology based on screen printing. To realize the data transmission and communication between the sensor and the monitoring center, the wireless transmission mode based on ZigBee technology and 485 wired transmission technology are used. In addition, the internet of things technology and multi data fusion technology are introduced to realize the interconnection between sensors. Based on the artificial intelligence algorithm, the state anomaly intelligent prediction model is established to carry out state early warning for the distribution room. After the multifunctional gas sensor performance tested, results show that the accuracy with <3% FS for the designed KIS-MS630A gas sensor. With the advantages of high detection accuracy, reliable data and stable operation, it is of great significance to realize the intelligent identification, monitoring and management of the operation state of the distribution room.
