Sewage treatment plant TCP/IP (transmission control protocol/Internet protocol) local area network automatic control system and method

Abstract

The invention discloses a sewage treatment plant TCP / IP (transmission control protocol / Internet protocol) local area network automatic control system and method. The sewage treatment plant TCP / IP local area network automatic control system is characterized in that a controller PIC16F877A achieves real-time data exchange of a communication chip W5500 through an SPI communication protocol, and serves as a main controller of SPI communication, when the controller independently achieves data acquisition and control instruction output controlled by a terminal, the controller PIC16F877A transmits the data communication chip W5500 of an associated register in real time and reads data transmitted from a local area network, the communication chip W5500 transmits the data to the local area network in a TCP / IP mode, the controller which meets the data address requirement receives the data and makes the corresponding movement response, digital control, digital acquisition and control and acquisition of the analog quantity of the terminal are achieved, and system automation is achieved. The sewage treatment plant TCP / IP local area network automatic control system has the advantages of being low in cost and long in service life.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage treatment plant TCP / IP local area network automatic control system and method, in particular, relates to a sewage treatment plant TCP / IP local area network automatic control system and method based on a PIC single-chip microcomputer. Background technique [0002] The automatic control technology of foreign sewage treatment plants started earlier, from large sewage treatment plants to small oxidation ponds, all adopt modern tools such as computer automatic control, remote control and closed-circuit television. my country's sewage treatment plants did not begin to introduce automatic control systems until after the 1990s, but most of them directly imported complete sets of foreign automatic control equipment, and the application of domestic automatic control systems is still relatively small. PID adjustment, ratio, feed-forward, feed-back, FCS (fieldbus control syst...

AI Technical Summary

Problems solved by technology

[0007] 1. The main control system is large in size and poor in encapsulation

[0008] 2. PLC (Programmable Logic Controller) is expensive, and the cost is particularly high, so it is not suitable for mass production of devices

[0009] 3. In industrial control, MCGS reads variables very slowly, which makes the system unable to process sewage in real time

[0010] 4. The sewage treatment system is a lagging system, which affects the timeliness of sewage treatment
