The Distribution automatic feeding system realizes a historical record of all measurement points on the basis of real-time trends. Once you need to trace the past data information, open the historical trend page, click the right mouse button on the blank space below, and in the pop-up dialog box, you can select any curve you want. Through the "Set Parameters" button on the Historical Trend page, the curve can be displayed according to the time period specified by the user. Meanwhile, the events occurred during the operation can be displayed in real time and queried in the history alarm page, the query content includes: time, date and time of alarm occurrence, alarm limit value, alarm recovery time, operation user, alarm variable name, etc.

The weighing crusher takes the hopper scale and the screw feeding mechanism as the entire scale body. Through the weighing instrument or PLC, the weight signal of the scale body is continuously sampled, and the change rate of weight per unit time is calculated as the instantaneous flow rate. Then, through various software and hardware filtering technologies, the "actual flow rate" that can be used as the control object is obtained. Then, the PLC performs control operations to approach the target flow rate through the PID feedback algorithm and outputs regulating signals to control the frequency converter and other feeder controllers.

The electronic scale of the oil drum handling vehicle adopts a clever combination of movement and electronic scale weighing. It can be weighed during handling or unloading. It is composed of a hydraulic handling mechanism and weighing components. The electric hydraulic scale platform can rise and fall, and the vehicle can be moved horizontally by manual push. Improve the professional production level of oil drum vehicle handling and measurement, expand the production scale of enterprises, and enhance the overall survival ability and competitiveness.

The weighing sensor uses the compensation network based on radial basis function neural network to complete the nonlinear error compensation of the sensor; In the lower limit region, a digital filter is used to complete the nonlinear error compensation. In the middle area, the weighing sensor does not compensate, and at the same time, the selection of subsection compensation is completed by using the adaptive selection network. The piecewise compensation model of nonlinear error is established to obtain good compensation effect.

Weighing sensor is a kind of mass (weight) measurement method that converts mass (weight) into electricity through the stressed structure. The output electric quantity signal and the input quality (weight) signal have a single value linear correspondence; It has the required accuracy and high sensitivity; It has good frequency response characteristics and less inertia; Little influence on the state of the weighed object; Able to work in poor environmental conditions; Good stability, reliability and long service life.

The Instruction Dosing System utilizes PLC as the central control area to complete the whole process of weighing and feeding. The PLC central control area sends out a signal to start the corresponding solenoid valve to inject the liquid into the reaction kettle, and at the same time, the weighing module starts to work. When the amount of liquid in the reaction kettle increases to the same value as the weight set by the quantitative setting finger, the central control area receives the action signal from the weighing module, and immediately closes the solenoid valve for adding liquid and stops adding liquid. Automatically start the stirring switch, the control area sends out the instruction to start the corresponding solenoid valve of the mixer and the timer set by the program starts to time, the mixer stirs the solution evenly; when the timer time reaches the set value, the control area sends out the instruction to close the solenoid valve and stops the stirring.

In the granular batching system, when the weighing module detects a shortage of material in the hopper scale, the pump motor starts and operates. The set feeding time and the feeding motor are activated and operate until the weighing module detects that the hopper scale is full of material, at which point all the working motors stop. The batching and discharging process of the system works as follows: when the weighing module detects that the material is in place and determines whether the measurement of the hopper scale by the weighing module reaches the set value, the discharging can be carried out.

Mixing Weighing dosing system based on PC and precise quantitative dosing is a set of machine, electricity, signal processing and dosing in one of the technical equipment, electrical part is mainly composed of weighing sensor, weighing instrument, programmable controller (PLC), frequency converter, industrial computer and printer. In the process of dynamic weighing, the weight signal of the weight sensor on the quantitative weighing hopper is received. When the weight of the material in the hopper reaches each set value, the output I/O quantitative signal to the PLC. PLC collects the quantitative output signal of the weighing display instrument, and controls the output frequency of each frequency converter through PLC, so as to control the thickness and fine feeding amount of the corresponding vibration feeder and the switching door action of each weighing hopper.

Pneumatic Liquid filling machine is used to send out the request to enter the car number, password, work number, filling and other commands, the weighing system is required to deal with the RF reader, weighing table data, communication of the upper PO and other serial data, the establishment of the barrel ID and information and staff permissions and other databases, so as to facilitate the effective query operation of the lower computer data uploaded when the database receives information indicating the car number and weight, the data is directly recorded in the database When the database receives the information indicating the car number and weight, the data will be recorded into the database directly, and each filling station can output statistics and reports on these data.
