To improve the communication performance and efficiency of gateway meter,the key application processes of embedded acquisition system integrated ethernet is designed.Firstly,the fault recorder data of gateway meter is customized in detail based on COMTRAD protocol.Secondly,the acquisition module automatically collects the latest COMTRADE history data generated in the meter and stores it to the FTP server through periodic query of UART.And the data files with large amount of data are interpolated to reduce the amount of transmitted data.Thirdly,a priority mechanism is proposed to realize efficient concurrent request management when multiple communication requests may exist between acquisition system and meter.Finally,the experiment verifies the improvement of query rate of automatic collection of historical data of meter compared with the traditional scheme,it provides a new solution idea for the efficient software development of the embedded Linux acquisition system in the gateway meter.
