Embodiment Construction
[0016] In order to describe the technical content, structural features, goals and effects of the present invention in detail, the following examples are given to describe the embodiments in conjunction with the accompanying drawings.
[0017] see figure 1 As shown, the present invention provides a flowmeter fault detection system of a water control system. The detection system includes a withholding fee system installed on the water control system, a data acquisition system and a host system, and each system is connected through a network system.
[0018] This system detects faults in the following ways: Step1, firstly mark each flow meter in the water control system network with a different serial number, and store and record it in the host system; Step2, the pre-deduction system starts to work before the user uses the water , first deduct the fixed fee, and then the water control system starts to release water according to the deducted fee. If the user still needs water afte...

The invention discloses a fault detecting system of flow meters of a water control system. The fault detecting system is characterized by comprising a pre-deduction system, a data collecting system and a host system, wherein the pre-deduction system, the data collecting system and the host system are installed on the water control system; a fault detecting method of the system includes the steps that 1, the flow meters in a water control system network are labeled with different serial numbers; 2, the pre-deduction system starts to work before users use water, a certain number of fees is deducted, and then the water control system starts to drain water according to the deducted fees; 3, the data collecting system reads and collects each-time deduction data of the pre-deduction system and processes the data into a chart; 4, the data collecting system reads and collects each-time water drainage data of the flow meters and then processes the data into a chart; 5, if the trends of curves of the two charts correspond to each other, it is indicated that the flow meters normally work, and if the water drainage data of the flow meters does not correspond to the pre-deduction data, it is indicated that the flow meters fail. By means of the system, waste of hot water resources is avoided, labor is saved, and manual one-by-one checking is avoided..
Description
technical field [0001] The invention relates to the field of water control systems, in particular to a flow meter fault detection system of the water control system. Background technique [0002] In today's increasingly tense energy environment, people pay more and more attention to the rational distribution and utilization of energy. Although water resources are relatively rich compared to other resources, with the rapid development of society in recent years, the available fresh water resources are becoming more and more At present, my country's water supply adopts metered charges. Whether it is general water supply, industrial water supply or hot water supply, most of the water control systems have a flowmeter in the system. Under normal circumstances, the flowmeter will generate a Hall signal according to the size of the current water flow, and then notify the control system of the amount of water flowing through. , so as to realize the function of billing according to v...
