Description

Technical Field

[0001] The present invention relates to a recovery guarantee method for a 5G gateway in a weak network disconnection in the application of the electric power industry, and belongs to the technical field of electromechanical equipment installation. Background Art

[0002] In actual use, 5G wireless networks may be unstable, with signal drift and signal strength jitter changes, which may cause network instability or even disconnection and inability to recover. The application scenarios of 5G in the power industry are mainly divided into: control services, collection services, mobile application services, and multi-station integration services. Taking differential protection as an example, 5G+distribution network differential protection monitors the real-time current values ​​of nodes at both ends of the distribution line through 5G gateways and 5G+distribution network differential protection terminals, and performs interactive comparison to determine whether the connection line is faulty. Once a fault is found, the faulty line is quickly located and cut off to complete fault isolation and avoid chain reactions. At the same time, the backup line can be started in real time to achieve fault recovery through line switching. These need to be based on the premise of 5G stable network and access. If the 5G gateway is unstable and cannot be restored, it will eventually lead to a long-term line failure that cannot be self-recovered. With the rapid development of 5G infrastructure construction and application in my country, 5G ToB networks have been continuously implemented in industries or fields such as power, smart factories, parks, security, cities, and live broadcasts, and have played a huge role. There are many control services and power services such as differential protection in the power industry. Once the network is disconnected for a long time, it may cause unpredictable consequences. In view of the needs of the special power industry, 5G networks are required to have high stability and high reliability, and be able to automatically restore the network and restore business links in the event of abnormal network disconnection to ensure the reliable operation of power services. There is no solution that can effectively solve this problem in the existing technology. Summary of the invention

[0003] In order to overcome the above problems, the present invention provides a recovery guarantee method for 5G gateway in weak network disconnection in the power industry application. The method detects and quickly processes through software to achieve the rapid recovery capability of 5G network when it is disconnected from the weak network, avoids the occurrence of long-term network anomalies, and reduces the failure loss of power business to a minimum, aiming to improve the network's self-recovery capability and ensure reliable and stable transmission of the network.

[0016] T5. Execute step T1 after a preset time.

[0017] Furthermore, the preset time is 60 seconds, the preset number of times of restarting the module protocol stack is 3, and the interval between each restart of the module protocol stack is 3 seconds.

[0018] Furthermore, in step T4, if the number of times the module protocol stack is restarted does not exceed a preset value, step T3 is executed, further comprising:

[0020] If T=1, then execute step T3 after 120 seconds;

[0021] If T=2, then execute step T4 after 180 seconds.

[0022] Furthermore, the recovery guarantee sub-process for dial-up disconnection is:

[0023] Perform the following steps when the dial-up is disconnected:

[0024] G1, let the number of restart module protocol stack be T, T=0;

[0025] G2, determine whether the dialing is normal, if so, execute step G4, otherwise execute step G3;

[0034] M4. Add 1 to the number of times the module protocol stack is restarted T, and determine whether the number of times the module protocol stack is restarted exceeds a preset value. If so, complete the hard recovery action by restarting the 5G module and end the process. Otherwise, execute step M5.

[0035] M5. Restart the module protocol stack and execute step M2;
