s102: the control module sends an instruction to each relay of the on-off module according to the test topological graph, the relays execute the instruction, so that the relay K1, the relay K2, the relay K4, the relay K5, the relay K7 and the relay K8 are all closed, and meanwhile, the relay K3, the relay K6 and the relay K9 are all opened;
s103: all network ports of the first test module perform ping tests, and the test result is as follows: the first group of electric cats to be tested ping fails, the second group of electric cats to be tested ping succeeds, and the third group of electric cats to be tested ping succeeds;
s104: the first test module generates two test topological graphs according to the test result and preset limiting conditions, the first test topological graph comprises a power modem 1 to be tested and a power modem 4 to be tested, the second test topological graph comprises a power modem 2 to be tested and a power modem 3 to be tested, and the two adjusted test topological graphs are sent to the control module;
s105: the control module controls the on-off of all relays according to the adjusted first test topological graph, namely the relay K1, the relay K3 and the relay K5 are closed, and the rest relays are all opened, so that the power modem 1 to be tested and the power modem 4 to be tested form a connected test circuit;
s106: the network port of the first test module, which is connected with the power modem 1 to be tested, performs ping test, and the test result is ping failure;
s107: the control module controls the on and off of all relays according to the adjusted second test topological graph, namely the relay K2, the relay K3 and the relay K4 are closed, and the rest relays are all opened, so that the power modem 2 to be tested and the power modem 3 to be tested form a connected test circuit;

a101: the first test module generates a test topological graph according to the distribution conditions of four electric cats to be tested, the test topological graph is in a point-to-multipoint networking mode, the four electric cats to be tested are communicated, and the electric cat to be tested 1 and other electric cats to be tested respectively form three communicated test circuits correspondingly;
a102: the control module sends an instruction to the on-off module according to the test topological graph, so that the power modem 1 to be tested is communicated with the power modem 2 to be tested, the power modem 4 to be tested and the power modem 6 to be tested, and the ping test is carried out on each test circuit in sequence;
a103: if at least one ping test is successful, the power cat 1 to be tested is normal, and then whether the power cat 2 to be tested, the power cat 4 to be tested and the power cat to be tested are normal can be judged according to each ping test result, taking the power cat 2 to be tested as an example, if the power cat 1 to be tested is communicated with the power cat 2 to be tested, if the ping test is successful, the power cat 2 to be tested is normal, and if the ping test is failed, the power cat 2 to be tested is in fault;
a104: if the three ping tests fail, the power cat 1 to be tested is confirmed to be normal by using the power cat to be tested, the power cat 1 to be tested is communicated with the power cat to be tested, if the ping tests succeed, the power cat 1 to be tested is indicated to be normal, and then the other power cats to be tested are indicated to be in fault; if the ping fails, the power cat 1 to be tested is indicated to be in fault, other power cats to be tested need to be communicated with the accompanying power cats respectively, and whether other power cats to be tested are normal or not is further confirmed respectively.
