Abstract

This application belongs to the technical field of accuracy correction, and relates to an electronic load-based automatic accuracy correction method and system. First, the test host is controlled to send preset instructions to test the backlight current data of different current gears on the motherboard to be tested; then the electronic load is controlled. Collect ADC data and feed it back to the test host, in which the electronic load forms a current loop with the main board to be tested; finally calculates the current difference based on the collected ADC data and the backlight current data reference value of different current gears, and controls the main board to be tested Compensate the corresponding current difference for different current gears. Therefore, through the electronic load automatic calibration method, the test host can obtain accurate values, the calibration accuracy is high, and the error caused by human operation is avoided; at the same time, no human operation is required, which reduces labor costs and solves the existing TV motherboard testing technology. There is a problem that the accuracy of the test results is not high due to errors.

Description

technical field [0001] The present application belongs to the technical field of accuracy correction, and in particular relates to an electronic load-based automatic accuracy correction method and system. Background technique [0002] At present, the purpose of testing the mainboard of a TV is to improve the accuracy of testing the backlight current value. Usually, the resistance used by the mainboard is measured to obtain the voltage value of the mainboard, and then the specific current value is calculated. However, this test method is not only inefficient, but also often has deviations in the instruments used for testing, resulting in different backlight current values ​​for each test. [0003] There are following disadvantages in the current method for detecting the main board current of a television set: [0004] 1. When detecting the backlight current value, there will be errors in the resistance value of each motherboard; [0005] 2. Due to the difference in test met...
