Detailed Description

The following describes a specific embodiment of the present utility model with reference to the drawings, taking temperature state monitoring based on a temperature sensor as an example. The temperature sensor 28 is connected to the collection endpoint 23, and then the collection endpoint 23 is connected to the PLC system 16 through the RS-485 bus 50, at this time, the temperature sensor 28 can upload data to the PLC system 16 through the collection endpoint 23. The data collection method is stored and executed as a program module by the collection endpoint 23, and after execution is completed, a control signal is sent, so that the temperature sensor 28 collects and uploads temperature data according to the control signal.

The acquisition endpoint 23 sends a control signal to the temperature sensor 28 causing it to acquire the temperature value of the current environment. Immediately, the temperature sensor 28 performs temperature data acquisition. The collection endpoint 23 parses, processes and stores the temperature values collected by the temperature sensor 28. When receiving a command for reading a temperature value transmitted from the PLC system 16, the acquisition endpoint 23 transmits the currently stored temperature value to the PLC system 16 via the RS-485 bus 50.

After the PLC system 16 receives the temperature value of the acquisition endpoint 23, the temperature value is analyzed, the temperature value is stored in a preset address, at the moment, a program in the PLC system 16 judges whether the temperature reaches a preset upper limit value, if so, the PLC system 16 sends a control instruction to the fan 18 to enable the fan to start working, the temperature of the environment is regulated, the current temperature value, the flag bit with the overrun temperature and the feedback value of the working state of the fan 18 are transmitted to the site control cabinet 11 and the switch 10 through the PLC system 16 through the RS-485 bus 50, and finally transmitted to the cloud server 5 through the pipe gallery network system 9, the core switch 8 and the firewall 7 and displayed on a computer of the pipe gallery total scheduling center 4.
