Weighing module refers to a weighing system that integrates the collection, amplification, transformation, transmission, processing and display of weight information. Its structural principle is to process elastic elements that feel vertical load and horizontal load at the same time on the weighing plate, and sense the weight of vertical force. It draws lessons from advanced technology and technology, and combines its long-term accumulated experience to integrate inventory management, formula management, ingredient weighing, process control and product traceability. Automatic technologies such as barcode (two-dimensional code /RFID) identification, wireless transmission, automatic weighing, PLC control, electromechanical, computer interface, etc. are adopted to independently develop and complete the intelligent formula weighing and inventory management system, so as to prevent wrong materials from appearing in ingredients, ensure weighing accuracy, ensure the accuracy of formula technology, make each batch of ingredient data recorded and traceable, and follow the principle of first-in first-out when raw materials are delivered from the warehouse, effectively solving the waste of raw materials.
020-34563445Measurement module is based on load cell, AD conversion circuit, microcontroller circuit, display circuit, keyboard circuit. Communication interface circuit, regulated power supply circuit and other circuit components. The use of modern sensor technology, electronic technology and computer technology integration of electronic weighing devices in order to meet and solve the real-life "fast, accurate, continuous, automatic" weighing requirements, while effectively eliminating human error, so that it is more in line with the legal system of measurement management and industrial production process control applications.
When an object is placed on the weighing module, pressure is applied to the load cell, which undergoes deformation, resulting in a change in impedance, and at the same time a change in the excitation voltage is used to output a variable analog signal. The signal is amplified by an amplifier circuit and output to an analog-to-digital converter, which converts the signal into a digital signal that can be easily processed and output to the CPU for calculation and control.The CPU outputs this result to the display according to the keyboard commands and the program. The CPU outputs the result to the display according to the keyboard commands and the program until the result is displayed.
Weighing module can be combined by touch screen + PLC (industrial computer control system) and automatic pneumatic valve, transfer pump, mixing kettle and Weighing system. Can be a variety of raw and auxiliary materials through a different order, at different temperatures through the PLC touch screen automatic control program to automatically mix, proportion, and realize the finished product production of the ideal automated liquid dispensing weighing equipment.
Weighing module data are stored in the control center's industrial computer database, the dosage process is monitored by the configuration software, the weighing control system implements the process operation through the control interface, the production data are stored in the system database at the right time, in order to complete the storage and analysis of all kinds of production data, and at the same time, it can also realize the management of raw materials and storage of material, finished product management, personnel management, contract management, and other functions.
