Overall tensioning control method and system suitable for large-plane prestressed structure

The invention provides an overall tensioning control method and system suitable for a large-plane prestressed structure, and the method comprises the steps: setting configuration parameters based on a preset tensioning program, transmitting the configuration parameters to a tensioning instrument, and controlling each jack to carry out synchronous and symmetrical tensioning according to a preset tensioning grade through the tensioning instrument; after each stage of tensioning is finished, tensioning data in the tensioning process are detected and recorded, and the tensioning data are uploaded to a monitoring platform for remote monitoring; and the tensioning data and the theoretical data are checked in real time, when the checking result does not meet the preset condition, tensioning is stopped, an alarm is given, configuration parameters are modified after reasons are found out, and tensioning is conducted again till the end. According to the method, overall synchronous symmetric tensioning is carried out ba
