The invention discloses a leakage monitoring system for a heat supply pipe network well type compensator, which includes a main control unit, the main control unit is connected with an A / D conversion module through a wire, and the A / D conversion module is respectively connected with a temperature measurement module, The conductivity sensor and the liquid level sensor are connected to the main control unit with a GPRS wireless module through wires, and the GPRS wireless module is connected to the remote monitoring center. The monitoring method is as follows: first, establish a sample input matrix, perform normalization processing, establish a prediction model for the leakage status of the heating pipe network well compensator, and finally use the measured parameters as input to obtain the heating pipe network well compensation device leak condition. Embed the multi-parameter compensator leakage state analysis based on the ELM extreme learning machine into the monitoring system for automatic, intelligent and scientific real-time online monitoring and leakage level evaluation, which can not only ensure the reliability and safety of the equipment, but also save A lot of manpower and material resources.
Description
technical field [0001] The invention belongs to the technical field of heat supply pipe leakage monitoring, and in particular relates to a leakage monitoring system of a heat supply pipe network well type compensator, and also relates to a monitoring method of the system. Background technique [0002] The heating pipeline compensator is an integral part of the heating pipeline network. The leakage monitoring method of the heating pipeline compensator belongs to the leakage monitoring method of the heating pipeline network. The leakage detection methods of the two are universal. As a heating system with complex and extremely large operating conditions, during its operation, due to the influence of various factors, pipeline damage and leakage accidents occur frequently. Monitor for leaks. Leakage monitoring of heating pipe network is a systematic project, which must use multiple means and interdisciplinary methods for its leakage monitoring. [0003] At present, scholars at ...
