Abstract

The invention discloses a BP neural network based temperature gain compensation method applied to an electronic scale. The method comprises the steps of: 101, establishing a neural network model for temperature gain correction of a weighing sensor; 102, obtaining learning training sample data of the network; 103, pre-processing the sample data; 104, performing network training on the number of samples; 105, testing the network prediction effect; and 106, writing a compensation formula into a firmware program of a single-chip microcomputer. The method of the invention can correct a temperaturesensor by using the neural network method, can quickly and accurately realize the temperature compensation of the weighing sensor, not only makes the accuracy of the compensation link reach the measurement allowable error range, but also has a prediction compensation effect for temperature points without training.

Description

technical field [0001] The invention belongs to the technical field of electronic scales, in particular to a protection device and method for touch screen equipment. Background technique [0002] In the field of electronic scales, sensors are easily affected by surrounding environmental factors in actual work, such as temperature, humidity, vibration, electric field, magnetic field, etc., especially the influence of temperature on sensors is the most significant. Temperature changes will cause additional output errors of the sensor; temperature will also cause corresponding changes in the parameters of the electronic components of the detection circuit [0003] The usual approach to this problem is to first place the load cell in a specific temperature environment for a long enough time to allow the temperature distribution to reach a steady state, then apply force to the load cell, and analyze and study by changing the different steady-state temperatures of the sensor The ...
