when the matching degree Z of the interface drive determined in real time is greater than the matching degree Z1 of the communication protocol, the data processing module extracts and records the unique identification of the task according to the general message format in the system, acquires the unique identification of the task control equipment, calls the corresponding equipment type data conversion according to the equipment type matched by the equipment identification, converts the content into the corresponding equipment communication protocol, and sends the protocol out through the corresponding communication interface;
when the matching degree Z of the interface drive determined in real time is greater than the matching degree Z2 of the communication interface and less than the matching degree Z1 of the communication protocol, the manufacturer information is unchanged, the equipment type is unchanged, and the communication protocol of the corresponding equipment type is replaced; when the matching degree Z of the interface drive determined in real time is larger than the lowest matching degree Z0 and smaller than the communication interface quasi-matching degree Z2, the manufacturer information is unchanged, and the corresponding equipment type is replaced; when the matching degree Z of the interface drive determined in real time is smaller than the lowest matching degree Z0, the manufacturer needs to be replaced, and the communication is stopped;
for the standard matching degree of a certain manufacturer, the acquisition mode is as follows:
obtaining the matching degrees Z1, Z2 and Zi of the corresponding interfaces, and calculating the average matching degree Zk = (Z1+ Z2+ … … + Zi)/i;
communication protocol match degree Z1=1.5 Zk;
the communication interface matching degree Z2=1.1 Zk;
the lowest matching degree Z0=0.9 Zk;
and setting a corresponding manufacturer equipment minimum matching degree matrix Z4 (A, T, Z3), wherein A represents manufacturer information, T represents equipment type, and Z3 represents the minimum matching degree of corresponding interface drive.
