基于GSM的远程温度控制监测系统摘 要 随着GSM移动通信网络的迅速普及和竞争的日益激烈，使得新技术和新业务的开发和应用提到了一个十分重要的位置。短消息业务（SMS）作为GSM网络的一种基本业务，已得到越来越多的系统运营商和系统开发商的重视。 现在随着工农业生产的发展，对环境的温度要求越来越高，使得温度测量与控制运用更加广泛。基于GSM的远程温度监测系统是通过移动通信网络来实现无线远程传输温度数据系统，采用这种方法来监测温度可以实现通信成本低、频谱利用率高、系统容量大、业务种类多、必威体育官网网址性能好、抗干扰能力强。这种对温度的控制是通过现有的GSM网络将检测结果以短信的方式发送至相应监测终端，通过控制中心分析处理来进行远程控制。本设计主要采用STC89C52单片机为主处理器，选用高精度数字温度传感器DS18B20为温度采集设备，使用SIM300GSM模块为短信收发设备，利用液晶屏LCD12864显示当前温度信息和报警信息，采用5个独立按键来实现温度上下限的设定和短信报警号码的设置，使用两个继电器来控制温度的上升和下降。因此，该远程温度控制系统可以实现室内，边远沙漠等偏远地方的温度控制，并且具有很高的准确性和及时性，是一个实用性很强的设计。 关键词： GSM；SMS短信息；远程监测；温度监测；STC89C52单片机 ABSTRACT With the widely popular of the GSM mobile communication network and the drastically Competition, new technique with new development and appliaction of the business have been a very important position.SMS have been so important for more and more ISP and ASP as one basic service of GSM network.With the development of industry and agriculture. the temperature of environment has high demand .makes the measurement and control of temperature is more widely used.Remote temperature monitoring syestem based on GSM is through the mobile communication network to realized wireless remote temperatur data transimsing system.Communication is realized by using this method to test the temperature can be low cost .high spectrum efficiency.large systemcapacity.business variety .confidentiality good performance .strong ant-interference ability.the contronl of the temperature is through the existing GSM network will test results in the form of text message sent to the corresponding terminial. Processing through the analysis of the control center for remote control.This design mainly adopts the 51 single-chip processor choose high precision digital temperature senor 18B20 temperatureacquisition device .using SIM300GSM module for SMS send and receive equipment.used LCD 12864 screen to display the current temperature and alarm information.using five independent keys to achieve the temperature upper and lower limilts set
