Abstract:
The monitoring and control terminal for transfer machine is developed. On the basis of processor STM32WB55CCU6, the different circuits have been designed, including the radio frequency signal detection circuit, ENC28J60 Ethernet data transmission circuit, RS-485 bus communication circuit, etc. Based on the sensor network of underground coal mine and the uCOS system, the terminal system software has been designed. The test results show that the distance between two nodes is within 70 meters, which can ensure the integrity and safety of data transmission. Besides, the response time of the remote monitoring terminal is less than 5 seconds.
