The weighing module integrates signal sampling, signal processing, and weighing algorithms. When any product requires weighing, simply embed this module directly into the product, occupying only one UART or RS232 resource. No weighing design experience is required, and the weighing function can be immediately realized. At the same time, digital weighing modules can also be configured to operate in different weighing modes, achieving intelligent weighing functions such as energy conservation and self-adjustment. According to the current market understanding, weighing modules are mainly applied in four fields.
020-34563445The explosion-proof weighing module is an integrated mechanical and electrical Weighing system that combines automatic control technology, Electronic scale measurement technology, sensor technology and computer management technology. It features digital display of weight values, dynamic display of process images, management of formula modification, fast batching speed, and high control accuracy. It adopts a full-screen control system based on an upper computer, and has functions such as automatic data storage, process list query, and statistics and printing of shift, daily, monthly and annual reports. It adopts an open control mode, has strong compatibility and an open database. It can be connected to the factory-level local area network via Ethernet, enabling integrated management and control.
The weighing module converts the data after analog-to-digital conversion into mass values through scale transformation and stores them in an array A of size 10 in the single-chip microcomputer, forming a sequence of mass values. The measured mass value reflects whether the device is in the weighing state or the seed brush sweeping the seeds. The rate of change of the mass value reflects whether the measured value has reached a stable state. When a stable state is reached, 20 values will be continuously sampled to calculate their average value. The result will be displayed on the LCD screen and stored in a specified block B of the single-chip microcomputer's Flash. After the quality measurement is completed, the data in block B is called up, and combined with the size of data block B (the size of data block B is the number of seeds being tested), the average and standard deviation of the quality are obtained.
