摘要
为提高现有液体醇基燃料储存和管理等环节的信息化水平,设计了一套基于GPRS技术的液体醇基燃料储罐网络化管理系统。该系统在每个储罐节点上采用STM32微控制器采集温度与液位参数并控制阀门,通过GPRS A9模组与远程服务器构建通信链路,采用MQTT协议上传节点状态并获取控制指令,实现在网络平台上对多个储罐节点进行状态监控、历史数据分析、异常状态预警分析以及远程指令下发。实验测试表明,该系统运行可靠稳定,可以对现有液体醇基燃料储罐进行改进和升级,为醇基燃料设备的安全运行提供支持。
To improve the level of information in the storage and management of existing liquid alcohol-based fuels,this article designed a new liquid alcohol-based fuel storage tank networked management system based on GPRS technology.The networked management system used STM32 microprocessor to collect temperature and liquid level,then use A9 GPRS to establish a connection with the remote server,using the MQTT protocol to upload and get commands.Users can monitor,analyzing historical data,predicting and send orders to multiple tanks.After experiments can see this system runs stably and can upgrade on the existing liquid alcohol-based fuel storage tank,it also gives safety support for alcohol-based fuel devices.
