Remote industrial pH process monitoring system based on WI-FI

Abstract

The invention discloses a remote industrial pH process monitoring system based on WI-FI and relates to a wireless monitoring system based on an endocrine mononeuron PID controller. The working flow of the system is as follows: on the one hand, an industrial personal computer accesses an MMF module through a wireless network composed of Wi-Fi modules and monitors the working state of a pH process device in real time; on the other hand, the MMF module regulates and controls output according to an endocrine mononeuron PID control algorithm so as to enable the pH process to quickly arrive at a stable state under a small overshooting premise. The remote industrial pH process monitoring system based on WI-FI is composed of a hardware system and a software. The hardware system is composed of a management unit, a wireless transmission unit and a control unit. The management unit is the industrial personal computer; the wireless transmission unit is used for connecting the management unit with the control unit and composed of a plurality of Wi-Fi modules; the control unit is composed of a monitoring server (MMF), an analog-digital converter, a digital-analog converter, an active low-pass filter and the pH process device. The software part is composed of software filter and endocrine mononeuron PID control algorithm.

Description

technical field [0001] The invention relates to a WI-FI-based industrial pH process remote monitoring system, which belongs to the technical field of pH process automatic control. Background technique [0002] In industrial production, in many cases, it is necessary to control the pH value during the chemical reaction process, such as pesticide and pharmaceutical production, heavy metal recovery in wastewater treatment, neutralization treatment before wastewater discharge, acid-base neutralization, etc. Most of the current pH process monitoring systems use wired networks. The wired network system not only has disadvantages such as poor mobility, inflexibility, poor scalability, and inconvenient networking and maintenance. With the development of wireless communication technology, the stability and real-time performance of wireless network have been greatly improved, which is enough to ensure the safe and stable operation of the control system. [0003] The pH process is a ...
