Meanwhile, the creation time of the first displacement message in the output text of the testing device is observed and compared with the trip information and the message creation time of the intelligent terminal, and if the trip time accords with a preset trip delay threshold (such as 20 ms), the accuracy of intelligent terminal element modeling can be proved.
