What is the method of obtaining flow and the principle of measurement accuracy for weightlessness
In the entire application process, the weightless scale will reasonably use its weighing and feeding company as all its weighing. During the entire application process, it will sample the net weight signal according to the symmetry that continues to appear on the dashboard of the car. In this way, the conversion rate of the weightlessness scale per unit time can be measured reasonably, and then the acceleration flow rate can be measured. For the acquisition of this type of flow, a weightlessness scale is very important, because it is the basis for accurate measurement and detection of products. The internal ant colony algorithm in the dashboard of this type of industrial equipment carries out control calculations close to the flow during use. Output adjustment signal to control soft starter, etc. The acquisition of this type of flow is very important, and it is also the basis for the accurate measurement and detection of a weightlessness scale. In the whole process of the actual application of the weightless scale, the product can be seen from the basic concept that its product is not vulnerable to the change of its net weight from one side of the scale to the other side of the scale. This is only the measurement of the net weight. The reason for the deviation, and the traditional dynamic measurement and detection method also has significant advantages. The weightlessness scale has a strong ability to transport raw materials, and its measurement and detection volume is high-precision when it is applied. It carries out accurate measurement for the silo during the whole work process. The actual measurement is carried out in the data format. The reason for the weight deviation is to calculate the flow rate. The reason for the deviation of the weightlessness scale and the error caused by the flow calibration value also depends on the accurate measurement time of the net weight of the product is more than ten minutes, and it is not easy to suffer from the damage of the sensor zero drift and temperature change during application, and then Can get higher measurement accuracy. The system without a net weight scale does not require steel, and its stainless steel plate will be selected during the entire process of application, so that it can be applied to sites with weaker geographical environment specifications, and the mechanical equipment has durability, less frequent maintenance, and no fear of high temperatures. And other characteristics, worry about high-temperature raw materials. The basic concept of the weightless scale is then based on the PID feedback and ant colony algorithm to carry out control calculations on the total flow close to the target, and output adjustment signals to control the feeder controller, such as a soft starter. The problems to be paid attention to when designing a weightless scale, and the element of damage accuracy: The weightless scale takes into account the characteristics of data format scales and visual data scales. Therefore, in the mapping software planning program, the requirements: 1. The appropriate range of the transportation rate. In general actual work, it refers to the range of 60% to 70% of the rated current of the delivery volume. If you choose to communicate and communicate, the frequency of the earth stress force is best in the middle of 35-40Hz. That can ensure the scope of the adjustment range. Also because the transmission speed is too low, the credibility of the system is weak. The measuring range of the sensor should be moderate, according to the calculation formula. The basic concept of a weightless scale, in other words, the detection range of the sensor also has a detection range of 60% to 70%, and the signal conversion range is wide, which is very useful for improving accuracy. 3. The design of the mechanical structure scheme should ensure that the fluidity of the raw materials is excellent. In addition, it is necessary to ensure that the replenishment time is short and the replenishment cannot be too short. Generally, it is required to replenish the material every 5 to ten minutes. The transmission system that cooperates with the machinery and equipment should ensure stable operation and excellent linearity.
