A ZigBee power wireless meter reading data sending and receiving terminal design

Abstract: a ZigBee power wireless meter reading data sending and receiving terminal design information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Introduction with the constant rise of the wireless network, due to the advantages of wireless network technology greatly, make more and more industry cable products and technology is replaced by wireless, wireless meter reading technology in our country, automatic ( AMR) As a new type of meter reading technology, have. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a ZigBee power wireless meter reading data sending and receiving terminal design article details. Introduction with the constant rise of the wireless network, due to the advantages of wireless network technology greatly, make more and more industry cable products and technology is replaced by wireless, wireless meter reading technology in our country, automatic ( AMR) As a new type of meter reading technology, with easy operation, low cost, no door, etc, as a kind of emerging ZigBee wireless network technology, with low power consumption, low speed, high reliability and strong confidentiality, etc. , at the same time to work on international free frequencies, higher than other wireless technology, the network cost, greatly reduces the cost, very suitable for application in automatic wireless meter reading system. In this paper, the design is an important part in wireless meter reading terminal and data collection mainly adopts RS485 bus and MCU control module, wireless transmission part USES the ZigBee wireless communication module. 4 working group, the network layer and application layer ( APL) Set by the ZigBee alliance. The physical layer defines the three level of traffic: when using 868 MHZ frequency, with 20 KB/s transmission rate; When using 915 MHZ, provide 40 KB/s transfer rate; 4 GHZ, able to provide 250 KB/s transmission rate, in our country is the free space. The data link layer can be divided into the logical link control sublayer ( LLC) And media access control layer ( MAC) Segmentation and reorganization, its function including data packets, the order of the packet transmission, the establishment of the wireless link, maintenance, and demolition, send and receive, confirm the frame model of channel access control, frame check and reserve a time slot and broadcast information management, etc. The function of network layer including topology management, MAC, routing management and security management. The application layer is the protocol stack of zui upper defines the various types of applications. The system is mainly involved in the design of data acquisition terminal node in the ZigBee network, also can be applied as a network router. 2 wireless data transceiver overall design RS485 bus terminal has a strong resistance to common mode interference ability, can undertake more and two-way communication, allow on a pair of twisted pair drive one or more of the equipment, so that you can achieve a transceiver to manage multiple user meters. Electric meter based on RS485 bus is simple easy to operate, low cost, many of them are on the market by RS485 smart meters, the system can be widely used. Wireless Zig - Bee module through the SPI interface receives data from the microcontroller system, signal will be sent the data signal. Wireless meter reading data sending and receiving terminals on the role of the whole meter reading system is the role of the routing and terminal, is a fully functional device FFD ( FullFunctionDevice) 。 The system overall design thought is: through the RS485 bus electric meter data collection, processing, and then through the MCU circuit through RS232, the SPI interface is sent to the ZigBee wireless communication module, block, zui after the use of wireless communication module is sent to a router nodes or network coordinator. The overall structure of the system is shown in figure 1. 3, sending and receiving terminal hardware design mainly includes: the terminal system electric meter data collection circuit, wireless transmission circuit and power circuit three parts. ( 1) Meter data collection circuit mainly is the MCU control circuit, deal with RS485 data sent to come over. Mainly include the MCU chip, RS485 control chip, optical coupling isolator, clock circuit, voltage regulator circuit, etc. ( 2) Wireless transmission circuit mainly through the SPI interface receives the MCU processing data, sent via RF radio frequency antenna.

The global market was valued at rosemount vortex flow meter in tuning fork liquid density meter and is expected to reach a market value of endress hauser ultrasonic flow meter by digital fork density meter, with a CAGR of v shape coriolis mass flow meter during the forecast period.
