摘要

The work that building the microscopic model and management the operation of water supply network needs to measure the pressure of selected nodes and users' time-sharing water consumption in practice. For test field there are many problems, such that the measured nodes is too many, the nodes is disperse, the periodicity of measurement is great, measure condition is bad, electric power can't be provided, workers can't keep to guard for a long time, data can easily be record in mistake. To avoid these, this paper put forward a solution which is an off-line and Ultra-power consumption for pressure and demand data time-sharing recording system. The system has been applied in Lvshunkou region , Dalian city successfully. This solution can solve the problem of measuring node pressure and users' time-sharing water consumption that can be finished completely by manual work in local, make the automatization of locale measurement come true. Through analyzing system power consumption, many methods which depress system power consumption have been put forward; analyzing the method that can avoid losing pulse during reading content in the counter in detail; and the application of water supply network system in Dalian lushunkou region is given.
