a first collation unit: if so, checking signal information of the preset signal in the second preset message with signal information of the preset signal in the first preset message one by one, wherein the signal information comprises bit length, initial byte position, initial bit position, precision and offset;
a second judgment unit: the second preset message is used for receiving the signal information of the preset signal in the second preset message;
a first determination unit: and if not, determining that error information exists in the target network segment signal matrix, wherein the error information is the signal information of the preset signal in the second preset message.
9. The system for matching target network segment signaling information of claim 8, wherein said matching module further comprises:
a second determination unit: and if the signal name of the preset signal cannot be found in the second preset message, determining that a missing signal exists in the target network segment signal matrix, wherein the missing signal is the preset signal.
10. The system for matching target network segment signaling information of claim 8, wherein said modification and padding module comprises:
a first generation unit: and the device is used for generating a first check report if error information exists in the target network segment signal matrix, wherein the information of the first check report comprises the name of the first preset message, the ID of the first preset message, the signal name of a preset signal in the first preset message, the signal information of a preset signal in the first preset message, the name of the second preset message, the ID of the second preset message, the signal name of a preset signal in the second preset message and the signal information of a preset signal in the second preset message, and the error information in the second preset message is marked by color.
