The invention discloses a device and method for detecting leakage of a conveying pipeline, and belongs to the technical field of fault detection. The device comprises one or more intelligent pressuretransmitters, electromagnetic flowmeters, a PC, a microprocessor, a GPRS communication module, an RS-232 serial communication interface, an RS485 bus and a power supply module. According to the deviceand method for detecting leakage of the conveying pipeline, pressure and flow signal data in the pipeline and at the tail end and head end of the pipeline are sequentially acquired through the intelligent pressure transmitters and the electromagnetic flowmeters, signals are transmitted to the microprocessor through the RS-232 serial communication interface, the microprocessor processes and storesthe data, then the data are sent to the GPRS communication module through the RS485 bus, then is transmitted to the PC through a GPRS remote data communication network, the PC processes, stores, analyzes and displays the signals, leakage signal detection and fault alarm are achieved, and finally an operator browses the operation condition of the ore pulp conveying pipeline at a client; and the pipeline leakage detection is realized on the basis of existing fault measurement data, the hardware is simple and convenient to construct, and site implementation is easy.
Description
technical field [0001] The invention relates to a leakage detection device and method of a conveying pipeline, which belongs to the technical field of fault detection. Background technique [0002] With the rapid development of various industries in our country, pipelines, as one of the five transportation methods, have been widely used due to their advantages of economy and convenience. , low pollution, large transportation volume, easy automation and management, etc. For complex terrain, landform and climatic conditions, its advantages are more obvious, so it has been widely used in the transportation of liquid, gas and slurry. For mineral transportation pipelines, the medium is mainly slurry, that is, minerals and water are mixed in a certain proportion and then transported. Use the pump as the power source to send the solid-liquid two-phase flow carrier to the smelter. As of the end of 2016, according to incomplete statistics, the length of various transmission pipeli...
