City tap water pipe network radio remote measuring and controlling intelligent terminal

Abstract

The terminal comprises measuring and controlling module of inserted form and GPRS radio communication module as measuring and controlling module consists of micropower photoelectronic scan transducer unit, detection unit of pipe network pressure, valve control and position, infrared communication unit, storage unit, microprocessor A, microprocessor B and monitoring unit of power supply and source. The transducer unit and detection unit of pipe network pressure are connected to microprocessor A as detection unit of vavel control and position, infrared communication unit, storage unit and GPRS communication module are connected to microprocessor B. The monitoring unit for power supply and power source are connected to other units separately.

Description

technical field [0001] The invention relates to a wireless remote measurement and control technology of a main pipe network in urban tap water production and water supply management, in particular to a wireless remote measurement and control intelligent terminal for an urban tap water pipe network. technical background [0002] In the existing technology, the domestic tap water supply management department mainly relies on the measurement, transmission and control of the three measurement and control parameters of the main pipe network flow, flow velocity, and pressure: the introduction of foreign "remote measurement and control systems"; domestic "remote measurement and control systems" or self-made radios Taiwan and so on. But the introduction of foreign "remote measurement and control system" is expensive, such as the 900 series of the Israeli BERMAD company, the price of its terminal equipment is 3-5 times that of domestic products, and the system cost is even more than ...

AI Technical Summary

Problems solved by technology

But the introduction of foreign "remote measurement and control system" is expensive, such as the 900 series of the Israeli BERMAD company, the price of its terminal equipment is 3-5 times that of domestic products, and the system cost is even more than 10 times that of similar domestic products; while the technology of the domestic system is complete The main problem is that the intelligence of the measurement and control terminal equipment is not enough, the measurement and control parameters are incomplete, the bit error rate of the data is high during the transmission process, and the fault tolerance of the system is not good; although the self-managed wireless station method can be reliable operation, but the high system cost and huge maintenance workload are also disadvantages that cannot be ignored
