Research And Realization Of Low Power Real - Time Acquisition And Transmission Of Water Supply Network Monitoring Data

GPRS is a relatively developed wireless transmission technology. Based on the universal data interchange platform, it can stably and fluently acquire and upload teledata which is widely applied in military, industrial monitoring, transportation, business and research, etc. Its mainly outstanding function is to transmit target data to control center and display control in a stable and realtime way.Now GPRS data acquisition has become one of the hot technologies of remote transmission control.The paper introduces the realtime acquisition and transmission system in low-power dissipation for the monitoring data of water supply network which relies on the GPRS universal data interchange platform. Implementing the data acquisition of analog quantity, switch value, and secondary instrument to use the platform of ultra-low-power singlechip microcomputer; designing the GSM communication and GPRS communication based on AT command mode and uploading the acquisition data to PC via GPRS to use eliminating-redundancies AT command measures;establishing separate communication protocol to conveniently realize data exchange fro m monitoring center to terminal; describing in detail about the overall design of the realtime acquisition and transmission system in low-power dissipation for the monitoring data of water supply network with design theme including CPM, GPRS module, data acquisition module, data memory module,detailed description on peripheral circuit of each function module, and fulfill the design of PCB circuit; finishing software design of slave computer including acquisition and memory of data, and data stability on mechanism, low power consumption, etc.
