through the way of comparison

Summer monsoon rains come, when the whole city drainage system will have a direct impact on people's normal life in the city, already cannot solve drainage canals passive actual difficulties, so many urban drainage pumping station by adding more urban dresses 1std drainage. But for the artificial control mode has already pumping to the modernization of the whole city. To enhance the automation of monitoring and control pumping ability of modern cheap nike shoes telecommunications, through the way of comparison, the use of existing GSM network realization of short message service advantages of telecommunications, and the way of drainage system applied to realize the automation and control the unattended.Aiming at the drainage system monitoring data system, based on the wireless communication field in recent years, the rapid development of Internet technology, the wedding dresses 2nd proposed GSM GSM network application of short message technology design of monitoring data transmission. Discusses the GSM system structure, main business, focusing on the short message service hot women's dresses characteristics, structure and common GSM AT instructions, and how to use the instructions AT realizing short message and based on the problems such as receiving the remote control system is shop 4u blog for shirts established. Through the use of advanced TC35 communication module and MCU, through the terminal system interconnection mig-at instructions, realized artificial using mobile phones to underground water collection and transmission and drainage pump and control. This paper introduces the main hardware part: system and single-chip microcomputer AT89S52 GSM communication module, A/D conversion, the level of the existing sensing technology and GSM network each part of the work principle and design method. Finally the system software flowchart and department molecular program flowchart. Introduces the technology of application. Finally puts forward some problems to be solved, and gives the solutions to these problems may ways and methods.
