Study on embedded system in monitoring of intelligent city pipeline network

摘要

The construction of an intelligent city needs healthy operation in all aspects. The monitoring of the intelligent city's pipeline network in the paper is studied to ensure its healthy development. The surveillance and management system of urban underground pipeline network can improve the efficiency of network resource management, shorten the maintenance time of pipeline network, reduce the cost of resource consumption, resource management cost, and ensure the healthy operation of society. The pipeline network monitoring system is based on an embedded system, which can realize functions such as viewing, historical data query, trend analysis, alarm record query, data export, report generation, etc. The operation condition monitoring module mainly implements real-time monitoring and alarming functions for the state parameters, for example, temperature drop, pressure drop and flow velocity of each pipe section in the pipeline network, and integrates the temperature, pressure and flow data of the pipeline network and the customer terminal. The safe operation range of state parameters and alarm upper and lower lines are set by intelligent decision analysis system of pipe network and to judge the damage situation and countermeasures. The system integrates operation condition monitoring, corrosion monitoring, water hammer monitoring and other modules. Meanwhile, the monitoring interface integrates intelligent alarm and pipeline network structure information. After preliminary data processing, the system communicates with host computer data. The system also integrates the local alarm function of fault signal and valve control. Through GPRS technology as a data transmission channel and the interaction between the upper computer in the central control room and the embedded unit in the lower computer of scene. The pipeline operation parameters can be transmitted and the intelligent city pipeline network monitoring system can be realized, which plays an important role in the healthy development of the city.
