Explosion-proof weighbridge is mainly a weighing instrument, PLC as an auxiliary control system, computer human-machine interface to display the proportioning parameters (formula) and monitoring and recording of real-time data, weighing instrument according to the set formula to open the weighing valve of the electronic scales, according to the weighing of the fast and slow with the amount of lead time, the weighing instrument detects the weighing of weighing scales to reach the set value, it will be subtracted from the amount of lead time, then close the feed valve. The advance amount can be corrected by human or automatically, so that the weighing instrument can control the electronic scale to reach the set target value every time.

Explosion-proof weighbridge consists of three basic units: weighing platform, load cell, and weighing instrument; the load cell part includes weighing instrument, weighing platform and signal cable. It adopts RS485 interface to communicate with digital load cell, and it can be adjusted manually/automatically for bias load (four-corner adjustment), address and read data of single sensor automatically, and modify the sensor number on the spot automatically. It can realize the processing of data, such as: display, calibration, sending, storage, printing and other functions.

Explosion-proof weighbridge will weigh objects placed on the load-bearing scales, there will be a certain gravity on top of the load-bearing scales, by the scales will be subjected to the distribution of force transmission to the various load cells, in the sensors, the original gravity signal through the deformation of the strain gauges of the force is transformed into an electronic signal, and then drive the electronic signals to the junction box for the organization of the convergence of the weighing instrument through the collection and processing of specific weighing information, after which the weighing value can be displayed. The weighing information is collected and processed by the weighing instrument, after which the weighing value can be displayed. In addition, the weight indicator can be connected with the computer, and the data information can be sorted out by the tool software, which is convenient for users to analyze the data and store the relevant work.

Explosion-proof electronic scales are connected to the computer for centralized control and all information is monitored by the upper management computer through the communication network to achieve optimal control. The whole weighing device has the advantages of decentralized monitoring of weighing instruments and centralized monitoring of computers, which not only realizes the centralization of management, operation and display, but also the decentralization of functions, loads and dangers. Based on the new generation of communication technology, management concept, industry characteristics of mineral production and sales, and the idea of precise management, the explosion-proof electronic scale realizes the goal of decentralized weighing in the weighing room within the cross-region range, centralized management by the weigher, prevention of cheating, and solves the problem of weighing management.

To achieve networked production management, the explosion-proof electronic scale needs to carry out structural stratification, including management layer, control layer, and equipment layer. The central switch is connected to the control network at the next level to monitor the entire control system, extract production data, and analyze reports. The control layer (composed of engineers and operators) can realize the programming, data analysis and storage of the entire control system; The equipment layer (production site) includes weighing instrument, 1/0 module and fieldbus, etc. The acquisition and conversion of various signals are completed by weighing instrument and 1/0 module, and the controller realizes the processing of logic control loop. The control mode after the weighing instrument is used as the core of the entire control system.

Explosion-proof weighing module can reduce the influence of "static uncertainty" of multi-fulcrum balance of weighing platform by adjusting the stress consistency of sensors, and ensure the stability of weighing platform support, so as to ensure that the bearing capacity of the center of gravity of weighing platform does not deviate, and achieve the accuracy of weighing instrument and relevant metering performance requirements. The weighing module has been compensated in many ways, including output sensitivity compensation.

The working principle of weighing module and the way of strain gauge bridge assembly, the data acquisition system consists of lower computer hardware and upper computer software, the software adopts LabVIEW programming technology, the weighing module obtains the radial pressure on the tilting table, the strain gauge under the tilting table generates strain due to the force, the lower computer obtains data signals, and through the serial communication module, the lower computer and the upper computer data acquisition system transmit instructions and data and process the collected signals. The information is transmitted to users by the upper computer panel. This system has the functions of data acquisition and processing, real-time data display and storage, post-processing of data and monitoring of working temperature.

The weighing module is a multi-channel weighing sensor. The sensors can meet the measurement requirements of different ranges by adjusting the distance between them. Its main function is to obtain the radial pressure of the table, realize the conversion of the local strain of the weighing module to the electrical signal, and then collect and process the electrical signal by using the data acquisition system.
