As shown in fig. 4, transmission channels of different grades
Before the transmission task starts, five classes of grades are designed according to the difference of the task generation time and the difference of the related attributes of the transmission content (the category, the generation time and the like of data), and from the first grade to the fifth grade, the grade of the transmission task in the transmission channel of the first grade is the highest, and the grade of the transmission task in the transmission channel of the fifth grade is the lowest.
As shown in fig. 5, the first level transmission channel: transmitting power data of the military; the level in the transmission channel of the same level changes along with the time of entering the transmission channel, and the task level entering the first level transmission channel at first is the highest.
As shown in fig. 6, the second level transmission channel: the electric power data of national units and public institutions are transmitted, the level in the same level transmission channel changes along with the time of entering the transmission channel, and the task level entering the first level transmission channel is higher.

There are 3 types of data transmission between the residential customer side and the power control center: abnormal data transmission, normal data transmission and calculation result data downloading.
And for the task of transmitting abnormal data, initially putting the task into a second-level transmission channel. And when the abnormal data in the second-level transmission channel exceeds the time limit, the abnormal data is transferred into a third-level transmission channel.
The task of transmitting normal data is put into the fourth level transmission channel, and a transmission task (a short signal) of the electric quantity demand signal is generated and put into the first level transmission channel. The main function of the electric quantity demand signal is to transmit the state information of the resident user terminal; the power control center is informed that the data transmitted at regular time is postponed to be transmitted, and the data is transmitted only after abnormal data with higher time requirement is completely transmitted. The main requirements contained in the electric quantity demand signal comprise information of a resident user side and normal data.
The task of informing the download of the calculation result data is put into the fifth level transmission channel.
Positive and negative feedback mechanism
When the actual effect of the anomaly detection algorithm is poor, the frequency of regularly transmitting normal data is too high, or the network condition is poor, the task completion speed is easily lower than the task generation speed, the transmission tasks of low-level normal data and calculation result data are overstocked, and a positive and negative feedback method is needed to be used for adjusting the anomaly detection algorithm and the transmission cycle of a resident user side, so that the diagnosis efficiency of the system is improved, and the data transmission pressure is reduced.
The invention realizes a positive feedback mechanism on the basis of a plurality of transmission channels with different grades. The concrete implementation is as follows:
when a specified number of backlogs of normal data transmission tasks continuously appear in the fourth-level transmission channel and the fifth-level transmission channel, the data transmission at the resident user side is abnormal or a certain adjustment space exists in an abnormal detection algorithm. The resident user terminal sends an electric quantity demand signal, finishes informing the electric power control center to update the algorithm and adjust the transmission frequency, and sends the result calculated by the algorithm to the resident user terminal from the electric power control center.
The fourth task is backlogged in the fourth-level transmission channel, a calculation result data updating task is sent out and is placed in the first-level transmission channel to update the calculation result data, but the original transmission task in the fourth-level transmission channel is not changed.
And accumulating a second task in the fifth-level transmission channel, sending an electric quantity demand signal, finishing the notification updating algorithm and the timing transmission frequency, inserting the task sending the electric quantity demand signal into the first-level transmission channel, simultaneously generating a task of downloading the calculation result data, and canceling all tasks in the fifth-level transmission channel. The former task of completing notification is to complete notification of updating algorithm and frequency information of the power control center and store the calculation result data in the power control center; the second goal of completing the notification task is to download new calculation result data from the power control center.
Bidirectional transmission mechanism of data
There are many data interactions in the transmission task, and a reliable two-way transmission mechanism needs to be designed,
the first step is as follows: the method comprises the steps that a resident user side sends an electric quantity demand signal, wherein the signal comprises the types of transmission tasks (normal transmission data, abnormal transmission data, calculation result data downloading, electric quantity demand signal sending and the like), ID of the resident user side, state information of the resident user side, a file name to be transmitted and the like; the power control center receives the electric quantity demand signal, processes corresponding demands according to task types, and generates a response signal, wherein the signal mainly comprises the demands such as state codes. The task type is file transmission, and the power control center needs to prepare for receiving a data packet according to a file name; the task type is to download the calculation result data, and the power control center searches a corresponding file according to the file name and prepares to send the file; the task type is that notification is finished, normal data are delayed to be sent, and the power control center needs to verify the state information of the resident user side; the task type is that the notification of updating algorithm and transmission frequency is completed, the power control center needs to update the algorithm and the frequency, and the result calculated by the algorithm is stored and waits for downloading.
If the transmission task is only to transmit the 'electric quantity demand signal', the next step is not needed, and if the transmission task is needed to transmit data, the next step is carried out.
The second step is that: and if the interaction between the resident user side and the power control center is successful and the data needs to be transmitted, the data is divided into small data packets and transmitted in a segmented mode. If the transmission task is carried out, the resident user side divides the data and then sends the data to the power control center. And if the task is a task of downloading the calculation result data, the power control center segments the data and sends the data to the resident user side.
The third step: the resident user terminal sends an electric quantity demand signal, and the demand in the signal comprises an ending demand (representing that the data packet transmission is ended), a hash code of a file and the like. The power control center receives the electric quantity demand signal, compares a value corresponding to the hash code demand with the hash code of the transmitted file, checks whether the file is transmitted correctly, and generates a response signal, wherein the demand in the signal comprises an end demand (end confirmation), a state code and the like. If the state code indicates that the file transmission is abnormal, re-entering the first step; otherwise, the transmission is finished and the task is finished.
