基于GPS和GSM的农场短信中心的设计与实现

为解决目前我国农场人工农机调度方式调度效率低、不及时等问题，设计并实现了基于GPS和GSM的农场短信中心。该农场短信中心集成了GPS的定位功能和GSM的通信功能，将GPS与农场调度中心联系起来，可以根据农机生产实际情况对农机进行合理调度。该农场短信中心基于中国移动的CMPP2．0协议，采用多线程处理技术和模块化设计方法，使用Java语言开发完成。试验结果表明，该农场短信中心短信处理时延〈2s／条，误码率〈0．01％，能够提供及时准确的短信处理，适用于农机车辆多于40台的农场。

Design and implementation of a GPS and GSM based farm short message center

The scheduling mode of agro-machineries is mainly manual scheduling in farm of China at present. This scheduling mode has many problems such as low scheduling efficiency and not timely. To solve these problems, a design and implementation of farm short message center (FSMC) was put forward, which was based on GPS,GSM. The FMSC integrated the powerful positioning GPS and good communication GSM, and connected GPS and scheduling center in farm, and realized reasonable scheduling agro-machineries in terms of agro-machineries working situation. The FSMC was based on CMPP2.0 of China Mobile and developed by Java language. Its implementation and design adopted multithreading technology and modularizing method. The experimental results showed that FSMC could deal with short message timely and exactly, whose processing delay was less than 2 seconds per piece and its bit-error ratio less than 0.01%. The FSMC is applicable for a farm with more than 40 agro-machineries.
