摘要
针对现有的库房环境监测系统通信效率低下,不能接入以太网等问题,设计了一个可以对环境参数进行实时监测并且具有远程操控设备能力的库房环境监控系统。系统主要由控制器和多个监测器构成,控制器和监测器都是采用基于ARM内核的STM32芯片,监测器上挂载了多种传感器对环境参数进行采集,控制器获取到监测器的数据并对异常情况做出反应,报警并自动打开库房内的安全设备,使库房环境参数恢复正常。控制器通过SPI接口与W5500芯片相连,在软件中将W5500驱动程序与FreeModbus协议栈结合,实现控制器和上位机的Modbus TCP协议通信功能。经过测试,智能库房环境监控系统能够实时监测库房内的环境参数,并且能通过以太网和上位机通信,完成数据的存储、查看和控制设备等功能,达到预期要求。
Aiming at the problems that the existing warehouse environment monitoring system has a low communication efficiency and can notaccess Ethernet, the new system is capable of real-time monitoring of environmental parameters and remote control device. The system is mainly composed of a controller and a plurality of monitors. The controller and the monitor both use STM32 chips based on the ARM core. The monitors are loaded with various sensors to collect environmental parameters. The controller obtains the data of the monitor and responds to the abnormal situation, alarms and automatically opens the safety equipment in the warehouse, so that the environmental parameters of the warehouse are restored to normal. The controller is connected to the W5500 chip through the SPI interface. The W5500 driver combined with FreeModbus protocol stack in the software to realize the Modbus TCP protocol communication function between the controller and the host computer. After testing, the intelligent warehouse environment monitoring system can monitor the environmental parameters of the warehouse in real time.And it can communicate with the host computer via Ethernet to complete the functions of storing, viewing the data and controlling the device to meet the expected requirements.
