摘要
针对现有的自动抄表方案成本高、功耗大、组网规模小、线路干扰等问题,提出一种新的无线抄表方案。结合ZigBee技术与GPRS网络,设计了一套远程无线抄表系统,局域网络采用ZigBee短距离无线通信技术,广域网络采用GPRS远程无线通信技术,组建的系统具有低成本、低功耗、自组网和自适应等特点,而且有较强的可移植性和兼容性。现场测试结果表明,该无线抄表系统能够快速准确地完成数据采集和传输任务,并具有较强的抗干扰能力和广泛的适用范围。
The existing meter reading method has many problems such as high cost, high consumption, small scale networking, and line interference, a new wireless meter reading method is proposed. A set of remote wireless meter reading system based on ZigBee technology and GPRS network is designed. ZigBee technology is used for lo-cal area network and GPRS technology is used for wide area network. The built system has low cost, low consump-tion, ad-hoc netwok, self-adaptive and so on, as well as strong portability and compatibility. The on site test results show that the wireless meter reading system not only can accomplish data acquisition and transmission accurately and quickly but also has strong anti-interference ability and wide application scope.
