摘要
针对无线自动抄表系统中表具数据的采集和无线传输问题,提出一种低成本、低功耗的解决方案.采用零功耗磁敏传感器、MSP430F123单片机和CC1100射频通信芯片对传统四表进行改造,设计了一种无线脉冲远传表.该仪表采用正负双脉冲采样技术,提高了抗电磁干扰能力;采用中断唤醒技术和电磁波唤醒技术,降低了功耗;制定了通信协议,实现了短距离无线通信.该仪表功耗低、计量准确、抗电磁干扰能力强,通信可靠,具有较高实用价值.
In order to solve the problem of meter data acquisition and wireless transmission in wireless automatic meter reading system,a low-cost、low-power solution is put forward.By adopting Zero-power magnetic sensor、MSP430F123 MCU and CC1100 radio frequency communication chip to transform the traditional four meters,a wireless pulse remote transmission meter is designed.By using the positive and negative double pulses sampling technology,anti-electromagnetic interference ability is improved;by adopting the interrupt wake-up technology and the radio wake-up technology,power consumption is reduced;by designing the communication protocol,short-distance wireless communication is realized.It has many characteristics,such as low-power,accurate measurement,strong anti-electromagnetic interference ability and reliable communication.So it has higher practical value.
