Coal Mine Dust Monitoring System-system structure framework

Simple text descriptions are involved in company secrets, so the structure chart will not be uploaded.

Host Computer: Dust Monitoring System Software

Lower COMPUTER: Dust Monitoring Base Stations, sensors, devices, etc.

Communication: RS--485

In fact, the design is basically a three-layer structure.

The entire system communication can adopt 485 communication and network port communication. The dust monitoring substation has its own network port function and can be directly connected to the ring network for use.

The difficulty of this system lies in the design and implementation of the lower computer base station. Unfortunately, I cannot understand the circuit diagram of the lower computer,

All said that software and hardware should be understood, and now cross-domain talents are justified.

PS: determine the next communication protocol...
