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.
