The design and implementation of a wireless meter reading system

This paper introduces the design and implementation of a Wi-Fi wireless meter reading system. The design of management software and wireless terminal including hardware and embedded software are introduced in detail. ARM9 and Linux are adopted for the implementation of wireless terminal. The communication between wireless terminal and management software is realized by the program based on Winsock. Access2003 is used for the storage of information. Smart Message Language (SML Protocol) is used to design the data structure aiming to make data communication maximally simple and suitable for implementation in low-power embedded systems and solve the communication problem between different equipment. A Wi-Fi network experiment system including a intelligent meter, a wireless terminal, an access point and the management software is constructed to test the performance of the wireless meter reading system and the result shows that the meter data can be correctly received and updated every two seconds which indicates that the system has good communication performance and reaches the purpose of meter reading, efficiently solving the low safety and efficiency problems of traditional meter reading.
