and a sixth step: when the client performs point matching on the point matching module: if the state type measuring point index and the test value information are issued before the writing value command issuing unit of the client-side point-to-point module, the real-time data acquiring unit of the client-side point-to-point module acquires and analyzes the measuring point signal message forwarded by the telecontrol device, and whether the measuring point is correctly matched is determined by comparing the test writing value command measuring point data with the GID number and the measuring point value of the measuring point in the received measuring point signal message; if the writing value command issuing unit issues measurement type measuring point indexes and test value information before, the real-time data acquiring unit acquires the GID number, the measuring point value, the value quality and other information of the corresponding measuring point by scanning the real-time database of the telecontrol device in real time, and compares the information with the measuring point information sent in the previous writing value to determine whether the corresponding measuring point is matched correctly. The data analysis comparison unit can distinguish normal signals and point aligning signals sent by the measurement and control protection device through the quality bits of the measurement point information, and further ensures that the normal operation of the measurement and control protection device is not influenced by the point aligning process through the identification of the quality bits. The state measurement point automatic alignment process interface is shown in fig. 4, and the measurement point automatic alignment process interface is shown in fig. 5;
the seventh step: and the comparison result output unit outputs point-to-point result information according to the judgment result of the sixth step, wherein the point-to-point result information comprises the total number of the measuring points, the failure number, the failure mark, the failure reason, the failure detailed information, the issued value, the reply value and the like for checking, saving or printing. The point result derived text is shown in fig. 6.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
