s1, the client controller sends tension control commands to the server controller respectively;
further, the S1 further includes: before distributing the control instruction, the client controller respectively establishes corresponding labels for the server controller, and then distributes the control instruction to the corresponding server controller according to the labels.
Specifically, the client controller monitors an externally input control instruction and establishes a corresponding label for the server controller; when the client controller monitors that an input control instruction exists, the client controller distributes the control instruction to the corresponding server controller according to the label;
s2, the server controller receives and executes the tensioning control command, generates receipt information after execution is completed, and sends the receipt information to the client controller;
s3, the client controller receives and summarizes the receipt information;
specifically, the client controller receives receipt information sent by the server controller, and regularly collects the received receipt information;
judging whether the summarized receipt information corresponds to all the server controllers or not, and if so, performing the next step; if not, the next summary is carried out;
s4, judging the execution condition of the summarized receipt information; if all execution is finished, ending the cable adjustment; if not, the client controller sends a control instruction to the server controller again.
During construction, after suspension cables of the suspension bridge are hung, an intelligent tensioning jack is installed at the tensioning end of each suspension cable; all the intelligent tensioning jacks are respectively connected with a server controller, and the server controller receives a control instruction sent by the client controller, controls the tensioning jacks connected with the server controller to execute the control instruction and sends back the execution information; the server controller is connected with the client controller respectively, and the client controller is used for controlling the issuing of instructions, receiving and processing receipt information and establishing an execution completion label;
