Abstract


With the rapid development of science and technology, the traditional meter reading technology is no longer suitable for the needs of today's property management, traditional meter reading technology there are a lot of negative factors, wireless automatic meter reading technology and its compared with households, low management costs, rapid, and avoid mistakenly copied the wrong copy. Automatic meter reading is automatically read and process the table data using computer technology and communications technology as a means to improve the level of automation needs of the energy management department, is the computer technology and communication technology rapid development inevitable. The design and functionality of this thesis, developed from the wireless meter reading system based on ZigBee technology transceiver functional blocks start to discuss the characteristics and applications of the ZigBee wireless access technology in this area, and specific relevant modules. ZigBee is a low-rate, low-power, short-range wireless access technologies, wireless network protocol is designed for low-rate sensor and control network design. Compared with other wireless protocols, ZigBee wireless protocol to achieve a low complexity, reduced resource requirements, and provides a set of standard specification. It provides three working band, as well as some network configurations and optional security features, standard control network designed for low-rate wireless network protocols. The paper first elaborated the Development of automatic meter reading market at home and abroad, the Project Background introduced ZigBee network topology, the ZigBee protocol layers of the structure and its function, and CC2430 various chips. The paper focuses on the design and functionality of the transceiver function module software. By the CC2430 chip peripheral circuits of the coordinator node and the node of the RFD (Reduced Function Device). The paper completed the hardware design of ZigBee communication module, communication software design and meter reading systems, data acquisition software design the CC2430 chip version of the test software design, ZigBee module. The complete realization of the hardware and software design based on the simulation and debugging of the software part. After the completion of the design, hardware and software with complete CC2430 version of the test, the ZigBee module between the communication and data acquisition. The formation of a network coordinator node ZigBee module communication first, then RFD node to apply to join the network, the coordinator node and the RFD nodes can receive and transmit network signal. During the design process, we fully take into account the the hardware node low power consumption, low cost, small size and other requirements. To reduce the node size, the components of the external package selection of surface mount components. Protel 99 SE circuit board design software design, first draw the circuit schematic, and complete schematic generated network table, and then proceed to the actual routing process to generate a printed circuit board. CC2430 combined DSSS (Direct Sequence Spread Spectrum) RF transceiver core and 8051 controller, its size is only 7 × 7mm. Can realize the digital baseband processor, RF, analog circuits and system memory are integrated on the same silicon wafer, to improve performance and meet the requirements of the ZigBee-based 2.4GHz ISM band applications for low-cost, low-power. CC2430 can be applied to various fields with its own advantages.
