13. The method as claimed in claim 12, wherein the step of the monitoring module testing the terminal under test according to the test instruction or the trial-jump instruction and feeding back the test signal to the handheld terminal comprises:
when the test command is a test command, the monitoring module tests the tested terminal based on the test command, generates the test signal and feeds the test signal back to the handheld terminal;
and when the test signal is a test jump command, the monitoring module tests the tested terminal based on the test jump command, generates the test signal and feeds the test signal back to the handheld terminal.
