Problems solved by technology
[0003] The traditional communication mechanism cannot guarantee the reliable transmission of information, timely feedback of abnormalities to users, and the arrival of information to the peer end according to the priority of information
The reliability of the traditional communication mechanism depends on the isolation device. If the communication of the isolation device is abnormal, the transmission data is blocked or lost, it will cause valid information and timely information to be unable to be transmitted to the opposite end, and all information will be transmitted on the same channel. Priority information Problems such as inability to prioritize transmission

Embodiment 1
[0035] Reliable transmission of data is realized through redundancy technology and adaptive data transmission technology. The solution monitors the transmission channel in real time, obtains information related to channel transmission, and combines the self-adaptive technology of machine learning to automatically adjust the transmission rate according to the current transmission flow, channel status, and transmission volume, reducing the communication failure rate of isolation devices.
[0036] Specific technical process such as image 3 as shown,
[0037] Reliable transmission technology: by image 3 It can be seen that reliable transmission is mainly composed of flow monitoring, adaptive control, load balancing and other parts.
[0038]Traffic monitoring: Traffic monitoring can sense the status of channel traffic in real time, including cumulative transmission volume, current transmission volume, transmission rate, etc.
[0039] Adaptive control: According to the traffic ...

According to the technical scheme, a power grid cross-region transmission communication system and method are used for achieving flow monitoring, flow monitoring senses the state of channel flow in real time, including accumulated transmission quantity, current transmission quantity, transmission rate and the like; and for achieving self-adaptive control, specifically, a current channel transmission situation is predicted by utilizing a Bayesian machine learning algorithm according to the flow monitoring data and the transmission data volume, an optimal channel is selected as a next transmission channel; and for achieving load balancing, specifically, when the data volume is transmitted concurrently, a transmission task is distributed according to the flow monitoring and channel transmission situation. The method has the beneficial effects that the network topology of cross-region transmission communication is not changed; the reliability, the concurrency and the transmission efficiency of cross-region transmission are improved, and under isolation equipment redundancy, when a plurality of cross-region transmission fails, the data transmission is not influenced; and after the hardware is restarted, data transmission is automatically recovered.
Description
technical field [0001] The invention relates to a communication system and method for power grid cross-regional transmission, belonging to the field of electric power communication. Background technique [0002] Cross-region transmission is very common and important in the power industry. The traditional cross-region transmission communication method is: information is sent to the communication port designated by the isolation device, and the isolation device will transfer the information to the opposite end according to the forward and reverse internal communication mechanism. [0003] The traditional communication mechanism cannot guarantee reliable transmission of information, timely feedback of abnormalities to users, and reaching the peer end according to the priority of information. The reliability of the traditional communication mechanism depends on the isolation device. If the communication of the isolation device is abnormal, the transmission data is blocked or los...
