Document Type and Number:
WIPO Patent Application WO/2019/071591
Kind Code:
A1
Abstract:
A voltage acquisition module calibration method, control platform and system, and a computer readable storage medium. The method comprises the steps of: obtaining voltage values Vsn collected by m voltage acquisition modules and X preset voltage value ranges Tn (14); classifying the voltage values Vsn collected by the m voltage acquisition modules according to the X preset voltage value ranges Tn, and fitting the classified data to obtain X corresponding voltage calibration coefficient curves (15); sending the fitted X corresponding voltage calibration coefficient curves to the voltage collecting module, such that the voltage values collected by the voltage acquisition modules according to the X corresponding voltage calibration coefficient curves are calibrated (16). The method does not require manual adjustment of the output voltage of a voltage reference source at intervals, ensuring the calibration reliability and high precision of the voltage acquisition module. A number of voltage acquisition modules can be synchronously calibrated, greatly improving the efficiency of calibration processes. The invention is suitable for a wide range of voltages and has high precision and low error.
