[Abstract]:With the popularization of central heating, thermal pipe network is widely used as a tool to transport heat medium. In view of the problem that expansion joint is liable to damage and cause leakage accident in thermal pipe network, this paper studies and designs a set of self-power supply, which is maintenance-free.Easy to install thermal pipe expansion joint damage leakage monitoring system.Thermal pipe expansion joint damage monitoring system mainly includes monitoring station, communication network and monitoring center.The monitoring station collects a variety of parameters around the outer wall of the expansion joint and transmits to the monitoring center through wireless network. The data fusion technology is used to analyze the test data in the monitoring center to realize the on-line monitoring of the operation status of the expansion joint.The monitoring station is installed near the expansion joint of the thermal pipe network. With the microprocessor STC89C54RD as the core, the temperature and soil conductivity data around the expansion joint are collected by 4 channels temperature sensor and 1 channel conductivity sensor.The data is processed with adaptive weighted data, and the data is transmitted to the data monitoring center through GPRS wireless network.A thermoelectricity generating device based on thermoelectric effect is also designed. The thermal network waste heat generation is used to supply power to the monitoring station continuously and stably, so as to adapt to the non-power environment.The monitoring center uses configuration software WinCC to display and store the data, and uses BP neural network algorithm to fuse the background data. The data reflecting the working condition parameters of expansion joint is trained and classified.According to the classification results, the expansion joint leakage is judged, and the corresponding maintenance plan is worked out according to the leakage level to prompt the staff to deal with it in time.The test results show that the output voltage of the thermoelectric unit can meet the requirements of the monitoring system.The simulation results show that the system can not only accurately judge whether the expansion joint is damaged or leaking, but also can get the leakage level.The application of this system can send out an alarm signal when the expansion joint is damaged and leaking, and prompt the staff to repair the expansion joint in time, and then reduce the damage caused by the expansion joint, which is of great significance to the protection of the normal heating of the residents.The self-supply thermal network expansion joint damage monitoring system designed and developed in this paper has been put into practical application in a certain thermal power plant, and the application effect is good, which meets the design requirements.
