A single-capacity water tank operation control system and method based on wireless communication

Abstract

The present invention provides a single-capacity water tank operation control system and method based on wireless communication. The system includes a single-capacity water tank system, an operation feedback control computer and a DCS monitoring computer; the single-capacity water tank system includes a pressure sensor, a liquid level sensor, and a flow sensor. , temperature sensor, water pump, reservoir, processor; the output end of the processor establishes a wireless connection with the input end of the operation feedback control computer, the output end of the processor communicates with the DCS monitoring computer through Ethernet, and the operation feedback control computer The output ends are respectively connected to water pumps and proportional valves; the present invention dynamically adjusts the liquid level setting value in each operation layer sampling period, so that the actual value of the operation index of the single-capacity water tank can track the target value, ensuring the random stability of the system, and can be wireless In the case of packet loss and noise in the transmission process, the actual value of the single-capacity water tank's operating index can track its target value, and the controller has a certain inhibitory effect on the external interference of the water tank.

Description

technical field [0001] The invention belongs to the field of industrial process control, and in particular relates to a single-capacity water tank operation control system and method based on wireless communication. Background technique [0002] In recent years, the control of liquid level and flow is often involved in many fields such as people's life and industrial production. There are more and more forms and methods of liquid level control, the technical performance is more advanced, and the degree of automation has also been greatly improved. However, as far as the liquid level control of various types of water tanks and pools is concerned, many projects have not reached the level of automation. Although some are designed with relatively precise instruments and other electrical equipment, they have not achieved sufficient development and reasonable configuration. , the automation program is low, there are many electrical and instrumentation devices, in the system only t...

AI Technical Summary

Problems solved by technology

However, there are packet loss and noise problems in wireless network transmission, which will lead to a decrease in system control performance and even instability

The closed-loop control of water tank operation with the coexistence of device network, Ethernet and wireless sensor network poses a challenge to the existing feedback control methods
