Abstract

The invention relates to a mobile remote operation and maintenance method for a load cell in chemical equipment. The method uses a data collector to collect flow sensor data and load cell data, medianfilter processing is then carried out on the collected data, average filter processing is then carried out, the collected data are later analyzed in real time through an intelligent calculation module, the flow sensor data are firstly analyzed, the weight of the material input is calculated, the linearity of the output value of the load cell is subjected to consistency evaluation according to theweight value on a weighing platform, and whether operation and maintenance are needed is further decided. The method can timely find out whether the load cell needs operation and maintenance, high-precision operation of the equipment is guaranteed, and a series of problems caused by untimely operation and maintenance can be avoided.

Description

technical field [0001] The invention belongs to the field of automation equipment, and in particular relates to a mobile remote operation and maintenance method for weighing sensors in chemical equipment. Background technique [0002] In chemical enterprises, the normal operation of equipment is the basis for ensuring efficient production, and good operation and maintenance is the prerequisite for ensuring the normal operation of equipment. The explosion-proof filling machine is a typical chemical equipment. During the filling process, the accuracy of each sensor must be ensured while ensuring the normal operation of the equipment. However, the accuracy of the load cell in the existing explosion-proof filling machine will decrease after a long period of use, that is, the input weight and the weight detected by the load cell are inconsistent, and operation and maintenance are required. At present, the commonly used method is that maintenance personnel go to the production si...
