[0002] At present, the operation status monitoring of distribution network protection devices mainly relies on manual regular inspections. The operation regulations require that the inspection cycle is 3 months. With the existing staff configuration, it is impossible to carry out inspections strictly according to the inspection cycle. In addition, the inspection cycle is long, and the inspection cycle cannot be guaranteed when the staff is tight. If defects occur during the inspection period, they cannot be grasped in time and need to wait until the next inspection to be discovered. The real-time grasp of the on-site situation cannot be guaranteed. At the same time, the technical level of the inspectors varies, and the quality of the inspection cannot be guaranteed. Summary of the invention

[0003] The purpose of the present invention is to provide a 5G mobile terminal and a protection self-healing device information interaction system and method, through the 61850 communication architecture of data transmission between the mobile terminal and the protection self-healing device of the distribution network, to achieve safe and reliable data interaction between the protection self-healing device and the mobile terminal, thereby reducing the cost of manual inspections.

Under the premise of not affecting the conventional protection and measurement and control functions, it can achieve convenient interoperability with other manufacturers at home and abroad with the support of the model self-description system; at the same time, IEC61850 also brings flexibility, real-time and other functional and performance improvements to the system.

[0028] The distributed configuration protection self-healing device supports all server-side MMS services of the TP link.
