The weighing tank system is a combination of weighing modules, weighing instruments and control systems. It can be directly connected to the PLC system and terminal control system to achieve multi-process control and automatic control. The communication between the on-site monitoring computer and the management computer was realized by using a local area network. The weighing control system software was developed in a modular way using VC++, which has a good control effect.

The weighing tank system is a combination of Weighing modules, weighing instruments and control systems. It can be directly connected to the PLC system and terminal control system to achieve multi-process control and automatic control. The system digitizes the weak weight signal output by the weighing module to obtain high-precision weighing data. The software is equipped with rich digital filtering technologies and emergency software to prevent the interference system from losing control, etc. Realize multi-process control and automatic control. The system digitizes the weak weight signal output by the weighing module to obtain high-precision weighing data.
Based on programmable intelligent modules, industrial control computers and RS485 fieldbus, the acquisition, processing, control and output of signals are realized, forming a cost-effective bucket scale Weighing system. The communication between the on-site monitoring computer and the management computer was realized by using a local area network. The weighing control system software is developed in a modular way using VC++ and has a good control effect. Real-time data requirements are implemented by the timer method, with a timing of 0.5 seconds. Each cycle completes data communication, input and output detection, control algorithm, output refresh, alarm output, and screen display operations. The implementation of data communication adopts multi-threading. The input of commands and data is implemented by the command and data input methods provided by the Windows operating system. The menu function enables command input, such as running, pausing, printing, etc., while the dialog box is used for data input.
By adopting PID algorithm and multi-loop regulation, the temperature inside the reactor is monitored in real time. It is precisely regulated through electric heating, steam heating or cooling water systems, with an error range that can be controlled within ±0.5℃. The integrated weighing module and mass flowmeter automatically adjust the feeding speed and reaction pressure to avoid abnormal reactions caused by overpressure or underpressure. According to the viscosity of the material and the reaction stage, dynamically adjust the stirring speed and mode (such as intermittent stirring, variable frequency speed regulation) to ensure uniform mixing of the material.
The SCADA system displays key parameters such as temperature, pressure, PH value, and rotational speed, and sets multiple alarm thresholds. When the parameters deviate from the set range, the system automatically triggers an audible and visual alarm and records the event. At the same time, it analyzes the cause of the fault (such as sensor failure, pipeline blockage) through AI algorithms. Integrated with a safety PLC and an emergency shutdown (ESD) system, it automatically cuts off power and initiates emergency measures in dangerous situations such as over-temperature, over-pressure, and leakage.
