Embodiment 1
[0018] Such as figure 1 As shown, the present invention provides a method for maintaining a constant-pressure water supply in an urban water supply network, and the technical principles of the method steps for maintaining a constant-pressure water supply are as follows:
[0019] A. Use digital radio to achieve long-distance data transmission. The digital radio adopts DSP technology and self-adaptive equalization. Set up a master digital radio in the city water system control center, and set up a master digital radio in each subordinate water plant to transmit data to each other. , mainly responsible for uploading the pressure, flow and water plant data of the main network;
[0020] B. Add pressure transmitters and electromagnetic flowmeter acquisition devices at the entrance and exit of the pipe network, the signal is transmitted wirelessly, and the data is transmitted to the monitoring center of the water delivery pump room through DSP, and the PLC of the water delivery pump ...
