Abstract

The present invention relates to a Windows CE embedded system based concentrator with environmental measurement, and especially a concentrator with environmental monitoring function. The concentrator comprises an embedded processor, and is characterized in that the embedded processor is connected with a sensor to obtain environment absolute atmospheric pressure, altitude and temperature data. The concentrator with intelligent environmental monitoring function provided by the invention is mainly used for collecting characteristics of system running state, success rate of meter reading, loss of data and AC analog quantity, and finally analyzing optimum parameters by using a BP neural network according to the collected characteristics, so as to enhance operation stability of the concentrator, and improve success rate of meter reading and acquisition accuracy of AC analog quantity. Therefore, the functions of improving operation stability of the concentrator and success rate of meter reading and enhancing acquisition accuracy of the AC analog quantity are realized. The concentrator also transmits collected characteristics to a master station platform through network for further analysis by the master station platform.

Description

technical field [0001] The invention relates to a concentrator based on Windows CE embedded system with environment measurement, especially a concentrator with environment detection function. Background technique [0002] In December 2009, the State Grid Corporation of China issued the "Functional Specifications for Power User Information Collection System" and other standards. According to the Q / GDW374.2-2009 "Technical Specifications for Centralized Meter Reading Terminals" in the new regulations, it is defined that the concentrator is equipped with the function of collecting DC analog quantities, that is, for some non-electrical quantity monitoring points (such as: temperature, pressure, etc.), It is converted into a DC analog quantity by a converter; the concentrator can collect the DC analog quantity in real time to measure non-electrical quantities such as temperature and pressure, and the measurement accuracy of the DC analog quantity is required to be within ±1%. Ho...
