The method comprises the following steps:

(1) The distribution automation terminal and the mobile APP keep a one-to-one relation, and one distribution automation terminal is only connected with one mobile APP for debugging at the same time.

(2) The mobile APP logs in and adopts unified authority authentication, information of a login account can be identified after each login, the information can distinguish the information of the city to which the account belongs, and the channel is distributed to different city GOMS systems based on the information.

(3) The interaction information of the mobile APP and the OMS system of the distribution network is provided with account information of the APP login every time. Based on this, the distribution network OMS system can know the APP login account number of each interaction.

(4) The distribution network OMS system forwards the information interacted by the mobile APP to the DMS system, and forwards the APP login account information to the DMS system at the same time of each forwarding, so that the information sent by the APP to the DMS system is realized, and the DMS system can distinguish which account is sent.

The remote signaling joint debugging device sets the remote signaling state of the field terminal to the debugging initial state before the remote signaling joint debugging is started, and after the remote signaling debugging request is sent on the joint debugging device, the DMS master station system acquires whether the current remote signaling value is consistent with the initial state or not. And after the remote signaling states of the DMS master station system and the field terminal are consistent, starting to debug the remote signaling function.

If the fault wave recording file of the debugging terminal is received within the set time, the debugging is successfully sent to the joint debugging device, otherwise, the debugging is failed.

(10) Other file transfer function verification

The other file transmission functions mainly comprise transmission and debugging of files such as terminal history logs and history loads, and the debugging flow is consistent with the wave recording files. After receiving the corresponding file calling request of the joint debugging device, the DMS master station system starts a debugging timing function and calls a corresponding calling command to call a file directory and a file to a tested terminal. If the corresponding file of the debugging terminal is received within the set time, the debugging is successfully sent to the joint debugging device, otherwise, the debugging is failed.
