Urban Central Heating Relay Pump Station Monitoring System Design

As the continuous development of the city central-heating, the diameter of supplying pipe net is enlarged, it caused that the supplying pipe net lost the balance, and it is hard to control the heating consumption, the mentioned-above problem is so serious. Therefore, for the product, transportation, delivery, and usage, they must be under a good condition, from the two aspects to solve them. One is the automatic control, and another is the management of heating industry. By the two ways, it can improve the overall standard on it. The technology on monitoring the heating project has the important role about ensuring the quality of supplying heating, safe running, and environment protection.This plan is mainly on the heat relay network backwater pressure pumping station, it is formed by the general monitor center, area monitor center, heating power and the data net. The goal is in overall way to know the situation of the heating system, and monitor the pressure data, adopting the dual-control strategy ( outside-net adjust, inside-net adjust), In the light of the typical large hysteretic controlling models, through wireless data networks and point-to-point fixed-line (dial-up) with the control center to monitor the network connection, to collect the data of the thermal heating station's operating temperature, pressure, flow, heat, and other parameters. And examine all heating equipments' running at any time, fault conditions, and also run heating planning under the operational aspect , to realize the local manual, automatic control and remote control functions. At the same time, it designs the network into a two-tier model, that is, control and management hierarchy, that is system control layer. the lower-level is divided into the monitoring systems engineer stations and operator station, the electric frequency-controlled areas, and the areas controlled by the on-site collection .This time the design proposal of the heat supply network's relay pump stations monitor program get involved in network technology, data acquisition technology, real-time two-way transmission of serial technology, object-oriented programming techniques and other technologies in internet data ,to achieve several inter-electric run with flexibility to and make the transducer run in maximum effectiveness .To achieve the goal of automation monitoring of urban central heating through technical means such as the shift ,solve difficulty of effectively controlling the heat, the network's out of balance, can not grasp the operating conditions and parameters on real-time, intensity of labor and other issues, to ensure the heating system run in a security, stability, reasonable motion.
