摘要
基于GSM短消息接口的温度遥测系统,其测量和数据采集由温度传感器芯片DS18B20完成,数据传输通过手机实现。手机短信发送由微控制器AT89C51处理,并向远端移动(或固定)手机发送温度值或报警信息。手机接口采用基于16进制字符PDU模式,包括设置PDU模式、检测Modem是否支持短消息、发送短消息等步骤。
For telemetering system for temperature based on short news interface of GSM, temperature measurement and data acquisition is completed by temperature sensor DS18B20, the data transport is realized by mobile telephone. The short letter in mobile telephone is sent out by micro-controller AT89C51, and the temperature value or alarming information was sent to remote (or fix) mobile telephone. The PDU mode based on hexadecimal word sign was used in interface of mobile telephone. The mode of PDU was set up, Modem was examined whether it supports short news or not, send out the short news etc.
