Embodiment Construction
[0019] figure 1 It is the entire system architecture, a large number of nodes constitute a wireless sensor network, the nodes collect gas concentration through sensor arrays, perform data filtering, temperature and humidity compensation, data preprocessing, and data fusion through DSP, and then send the processed data to Convergence node, the convergence node is uploaded to the upper computer through the mobile communication network, and the upper computer includes a remote database and a remote monitoring terminal.
[0020] In a gas chamber, the gas enters the reaction chamber through the gas valve, and the sensor array will detect the gas. Considering that the electronic nose gas detection system with protection function we designed may be used for highly corrosive gases If the sensor is in contact with corrosive gas for a long time, it will damage the sensor, which will greatly reduce the life of the sensor, increase the frequency of sensor replacement, and increase the cos...
