摘要
设计了一种基于GSM模块的无线智能抄表系统,该系统包括上位机、下位机和电表终端三部分。上位机软件通过MAX202对GSM模块进行控制,以短信指令的形式与下位机完成通信。下位机接收上位机发送的短信指令,并将其送入单片机进行处理,通过VP3082将接口转化为RS485接口,与电表终端进行通信,实现数据的读取,再将读取的信息通过GSM模块返回给上位机,最终将数据显示在PC上,从而实现无线智能抄表。该系统解决了传统抄表价格昂贵且效率低等问题。
The paper designs a kind of wireless and automatic electric meter reading system based on GSM. This system contains upper computer, lower computer and terminal. The upper computer controls GSM module by MAX202, in order to communicate with lower computer, the lower computer receives the message sent by the upper computer, and sends it to single chip microcomputer. According to different messages, single chip microcomputer sends different orders to terminal by VP3082 which converts the interface to RS485. It gets the required information, and the sends the information back to the upper computer through GSM module. At last, it displays tbe information on PC, and redizes wireless and automatic electric meter. It has solved some problems like price and poor efficiency of traditional meter reading system.
