[0039] In the power system, power communication is an important technology to ensure the stable operation of the power grid, realize remote monitoring and dispatching, and exchange data. With the development of smart grids, higher requirements are placed on the real-time, reliability and efficiency of power communication. Traditional power communication systems often rely on a single communicator for data transmission. This design is prone to communication bottlenecks when facing complex and changing power grid environments and growing data transmission needs, affecting the overall performance and communication efficiency of the power system.

[0040] In view of the above problems, the present application proposes a communication status monitoring management method for power communication, which is applied to a communication status monitoring management system, wherein the communication status monitoring management system comprises a first communicator 100, a second communicator 200, a communication status monitoring evaluation unit 300 and a switching circuit 400, wherein the switching circuit 400 is used for switching between the first communicator and the second communicator so that the first communicator or the second communicator is connected to the main circuit for power data communication transmission. Figure 1 As shown, the switching circuit 400 may include a switch S1 and a switch S2, and the switches S1 and S2 may be interlocked, that is, the switch S2 is closed when the switch S1 is disconnected, and the switch S2 is disconnected when the switch S1 is closed. One of the first communicator 100 and the second communicator 200 may be a main communicator, and the other may be a backup communicator; or, one of the first communicator 100 and the second communicator 200 may be a local data communicator, and the other may be a remote data communicator, and one of them may be used as a backup communicator under special circumstances. The embodiment of the present application deploys multiple communicators in the power communication network to ensure that when the main communicator fails or the performance degrades, it can quickly switch to the backup communicator to ensure the continuity and stability of the power communication.

[0041] It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here. Figure 2 The method comprises the following steps S100 to S500:

[0042] S100, when the first communicator is connected to a main circuit for power communication, obtaining communication status data of the first communicator, wherein the communication status data includes a power data reading and writing rate value and a power data reading and writing accuracy value;

[0043] Specifically, the first communicator and / or the second communicator are connected to the communication status monitoring and evaluation unit through a hardware interface to transmit communication status data. These interfaces can be standard communication interfaces, such as RS-232, RS-485, Ethernet interface (Ethernet) or wireless communication interface (such as Wi-Fi, Zigbee, etc.); a data acquisition module is provided inside or outside the communicator to capture key parameters in the communication process in real time, such as the sending and receiving timestamps of the data packets, the integrity and verification results of the data packets, etc.; according to the timestamp information provided by the data acquisition module, the amount of data successfully transmitted per unit time, that is, the reading and writing rate value of the power data, is calculated. In addition, the integrity and accuracy of the data are checked by comparing the contents of the sent data packets with the received data packets. The accuracy can be obtained by calculating the ratio of the number of data packets successfully received and correctly parsed to the total number of data packets sent.

[0044] In other embodiments, the communication status data of the second communicator can also be obtained through the above calculation method or other methods.

[0045] S200. Input the communication status data of the first communicator into the communication status monitoring and evaluation unit to obtain a communication efficiency characterization value of the first communicator;

[0046] In one embodiment, a pre-trained communication status monitoring and evaluation model is stored in the communication status monitoring and evaluation unit. The step S200: Input the communication status data of the first communicator into the communication status monitoring and evaluation unit to obtain a communication efficiency characterization value of the first communicator, includes:

[0047] Input the communication status data (power data read / write rate value and power data read / write accuracy rate value) of the first communicator into the pre-trained communication status monitoring and evaluation model to obtain a communication efficiency characterization value of the first communicator. The communication status monitoring and evaluation model satisfies the following expression: ;

[0048] where, T is the communication efficiency characterization value, R is the current power data read / write rate value, R0 is the reference power data read / write rate value, A is the current power data read / write accuracy rate value, A0 is the reference power data read / write accuracy rate value, K is the performance load of the first communicator, 0 < K ≤ 1, and the performance load represents the original performance size of the communicator. Gr is the performance loss coefficient, 0 < Gr < 1, and the performance loss coefficient Gr is positively correlated with the usage load of the communicator. W1 and W2 are the corresponding influence weights, that is, W1 is the influence weight of the read / write rate value on the overall communication efficiency, and W2 is the influence weight of the read / write accuracy rate value on the overall communication efficiency.

[0049] Specifically, in the embodiment of the present application, when constructing the communication status monitoring and evaluation model, it is considered that the usage load (such as usage duration or temperature generated during use) causes losses to the data transmission performance of the communicator. The above communication status monitoring and evaluation model is obtained by collecting a large amount of data for model training and parameter calibration. And when the performance load K of the first communicator is 0.8, after the first communicator is used for 50h, the performance loss coefficient is determined to be 0.1, that is, the data read / write efficiency reference value of the first communicator becomes 0.8×(1 - 0.1) = 0.72 after being used for 50h. At this time, the data read / write efficiency value , and then the final communication efficiency characterization value can be obtained by using the current read / write rate value, the reference read / write rate value, the current read / write accuracy rate value, and the reference read / write accuracy rate value. For the convenience of calculation, in the embodiment of the present application, the influence weights W1 of the read / write rate value on the overall communication efficiency and W2 of the read / write accuracy rate value on the overall communication efficiency are given the same weight, that is, both are 50%.

[0050] S300, when the communication efficiency characterization value of the first communicator is less than or equal to the efficiency threshold, switching the first communicator to a second communicator so that the second communicator is connected to the main circuit for power communication;

[0051] Specifically, when the communication status monitoring and evaluation model detects that the communication efficiency characterization value of the first communicator drops below the efficiency threshold, it means that the data transmission performance of the first communicator has been significantly affected. At this time, the system automatically switches to the second communicator, which is connected to the main circuit and takes over the power communication task of the first communicator. In this way, the first communicator can be effectively protected to ensure that its service life and performance are not damaged.

[0052] In one embodiment, before switching the first communicator to the second communicator so that the second communicator is connected to the main circuit for power communication, the method further includes:

[0053] The state of the second communicator is detected to ensure that the second communicator is in an available state, where the available state indicates that the second communicator is not performing other communication tasks and the current temperature is within a temperature threshold range.

[0054] Specifically, when it is necessary to switch the first communicator to the second communicator so that the second communicator can access the main circuit for power communication, the system must first ensure that the second communicator is in an available state. This step is crucial to maintaining the stability and reliability of the system. In order to ensure the availability of the second communicator, the system will perform a series of status checks on it. These checks include but are not limited to (1) communication task detection: the system will check whether the second communicator is performing other communication tasks. If the second communicator is already busy (caused by some faults), it cannot immediately take over the task of the main communicator. Only when the second communicator is idle can the switch be made. (2) temperature detection: the system will monitor the current temperature of the second communicator to ensure that it is within the temperature threshold range. If the temperature of the second communicator is too high, it may not be able to effectively handle the communication task, and may even be damaged due to overheating. Therefore, temperature detection is an important part of ensuring the availability of the second communicator. Only when the second communicator passes all status checks and is confirmed to be in an available state will the system perform the switching operation to allow the second communicator to access the main circuit for power communication.

[0055] S400, determining in real time during the power communication process the load conditions of the first communicator and the second communicator, and determining the load difference between the first communicator and the second communicator;

[0056] The load conditions of the first communicator and the second communicator may refer to the load of working time or the temperature load caused by heating. Therefore, the load difference between the first communicator and the second communicator may refer to the load difference of working time or the temperature load difference.

[0057] In a specific embodiment, the load difference between the first communicator and the second communicator includes a current temperature difference. In the embodiment of the present application, the load conditions of the first communicator and the second communicator are collected and judged in real time to provide an accurate data basis for subsequent intelligent switching of the communicators.

[0058] S500: When the first communicator is not overloaded and the load difference between the second communicator and the first communicator is greater than or equal to a preset value, re-switching the communicator to perform power communication through the first communicator.

[0059] In one embodiment, the step S500: when the first communicator is not overloaded and the load difference between the second communicator and the first communicator is greater than or equal to a preset value, re-switching the communicator to perform power communication through the first communicator includes:

[0060] When the current temperature of the first communicator does not exceed the temperature threshold and the current temperature difference between the second communicator and the first communicator is greater than or equal to a preset value, the communicator switching is performed again to perform power communication through the first communicator.

[0061] Specifically, when the system monitors that the current operating temperature of the first communicator does not exceed the preset temperature threshold, this indicates that the first communicator is not at risk of performance degradation or damage due to overheating. At the same time, if the system further detects that the current temperature difference between the second communicator and the first communicator reaches or exceeds the preset difference threshold, this means that compared with the second communicator, the first communicator currently has a lower operating temperature, so its potential heat dissipation pressure is smaller and its performance may be more stable. At this time, the communicator is switched again to perform power communication through the first communicator. In this way, based on the above dual condition judgment, the system will trigger the communicator's re-switching mechanism, that is, switching the power communication task originally undertaken by the second communicator back to the first communicator. The purpose of this decision is to make full use of the current superior working state of the first communicator to optimize the overall performance of power communication, and it also helps to balance the workload of the two communicators and extend their overall service life.

[0062] In other embodiments, before re-switching the communicator to perform power communication through the first communicator, the method further includes:

[0063] The communication efficiency of the first communicator after reconnecting to the main circuit is predicted based on historical data, and when the predicted communication efficiency is higher than an efficiency threshold, the communicator is switched again to perform power communication through the first communicator.

[0064] Specifically, firstly, the time interval for the first communicator to resume power communication is obtained to obtain the recovery time; and the recovery time is input into a communication efficiency recovery mapping table pre-established according to historical data to obtain the current communication efficiency value of the first communicator.

[0065] In the communication status monitoring and management system of the power communication of the present application, when considering reconnecting the first communicator to the main circuit for power communication, the system not only relies on the instant status detection, but also predicts the communication efficiency of the first communicator after reconnection based on historical data. In this way, it can be ensured that before switching back to the first communicator, it can perform the communication task in an efficient and stable state. In order to make this prediction, the embodiment of the present application first obtains the time interval from the end of the last communication task to the current attempt to reconnect, which is called the recovery time. The recovery time is crucial for evaluating the cooling effect and readiness of the first communicator. Then this recovery time is input into a communication efficiency recovery mapping table pre-established based on historical data. This mapping table is a database that records the communication efficiency values ​​of the first communicator under different recovery times. By searching the mapping table, the system can quickly and accurately obtain the expected communication efficiency value of the first communicator under the current recovery time. If the predicted communication efficiency is higher than the preset efficiency threshold, the system will consider that the first communicator is ready to reconnect to the main circuit for power communication. At this time, the system will perform a communicator switching operation to switch the communication task from the second communicator back to the first communicator. This not only improves the flexibility and response speed of the power communication system, but also ensures that the communication task always remains efficient and stable during execution. By combining historical data and real-time status detection, the system can make more intelligent switching decisions, thereby providing users with better power communication services.

[0066] In another embodiment, after the step S400 of determining the load conditions of the first communicator and the second communicator in real time during the power communication process and determining the load difference between the first communicator and the second communicator, further comprises:

[0067] In the case that both the first communicator and the second communicator are overloaded, the first communicator and the second communicator are controlled to perform intermittent switching so as to perform power communication alternately through the first communicator or the second communicator in a preset cycle period.

[0068] Specifically, during the power communication process, the load conditions of the first communicator and the second communicator are monitored in real time, and the load difference between them is determined, which can further ensure the communication efficiency and system stability. When the system detects that both the first communicator and the second communicator are in an overload state, it means that both the first communicator and the second communicator are facing greater working pressure and may not be able to continuously provide stable power communication services. In order to cope with this situation, the embodiment of the present application adopts an effective load balancing strategy to reduce the burden of the communicator and extend its service life. A feasible solution is to control the first communicator and the second communicator to perform intermittent switching, and alternately undertake the power communication task with a preset cycle. Specifically, the system automatically adjusts the switching strategy of the communicator according to the current load condition and the preset switching cycle. At each switch, the system evaluates the load status of the two communicators and selects the communicator with a relatively low load to take over the power communication task. In this way, the system can achieve load balancing between the two communicators while ensuring the continuity of power communication, and avoid damage to a single communicator due to long-term overload work. In addition, the preset cycle can be adjusted according to actual conditions. For example, when the system load is high, the switching cycle can be shortened appropriately to alternately use the two communicators more frequently, thereby distributing the load more effectively. When the system load is low, the switching cycle can be extended to reduce the additional burden caused by communicator switching.

[0069] In one embodiment, the first communicator is a main communication device, and the second communicator is a backup communication device. When both the first communicator and the second communicator are overloaded, controlling the first communicator and the second communicator to perform intermittent switching to alternately perform power communication through the first communicator or the second communicator in a preset cycle period includes:

[0070] When the current temperatures of the main communication device and the backup communication device exceed the temperature threshold, the main communication device and the backup communication device are controlled to perform intermittent switching so as to perform power communication alternately through the main communication device or the backup communication device in a preset cycle; wherein, within a complete preset cycle, the communication duration of the main communication device is greater than the communication duration of the backup communication device.

[0071] Specifically, when the power communication system faces a situation where both the main communication device (i.e., the first communicator) and the backup communication device (i.e., the second communicator) are overloaded, especially when their current temperatures exceed the preset temperature threshold, the system will start an intermittent switching mechanism to maintain the continuity of power communication. This intermittent switching mechanism uses the main communication device and the backup communication device for power communication alternately based on a preset cycle. It should be noted that since both the first communicator and the second communicator are overloaded, the second communicator is most likely to heat up too quickly during operation, and has not yet waited for the first communicator to dissipate heat to a safe state, resulting in the main communication device (i.e., the first communicator) and the backup communication device (i.e., the second communicator) are both overloaded. The embodiment of the present application takes into account the above reasons, and also considers that the main communication device usually has higher performance and stability. Therefore, when conditions permit, the main communication device is used first to ensure the quality and efficiency of power communication. That is, in a complete preset cycle, the communication duration of the main communication device is set to be greater than the communication duration of the backup communication device (for example, in a 3-minute cycle, the communication duration of the main communication device is 2 minutes, and the communication duration of the backup communication device is 1 minute). In this way, not only the continuity and stability of power communication are guaranteed, but also the load and heat dissipation requirements of communication equipment are effectively balanced, ensuring the long-term reliable operation of the system.

[0072] In one embodiment, the method also includes: obtaining the temperature rise rate of the first communicator and the second communicator based on the temperature data of the first communicator and the second communicator during the historical communication process; selecting the one with a larger temperature rise rate between the first communicator and the second communicator as the backup communication device and triggering an early warning signal, wherein the early warning signal is used to prompt timely replacement of the backup communication device.

[0073] Specifically, the embodiment of the present application not only focuses on the current communicator load and temperature conditions, but also deeply analyzes the temperature data of the first communicator (main communication device) and the second communicator (backup communication device) during the historical communication process. Through these data, the temperature rise rate of each communicator can be calculated. The temperature rise rate is a key indicator that can reflect the heating conditions and potential thermal management problems of the communicator during operation. After calculating the temperature rise rate, the system will compare to determine which communicator has a higher temperature rise rate. Since a communicator with a faster temperature rise rate may face greater heat dissipation pressure and a higher risk of failure, the system will select this communicator as a backup communication device and trigger an early warning signal at the same time. The early warning signal can promptly remind the operator to pay attention to the thermal management problems of the communicator, and can also provide an important basis for the timely replacement or maintenance of backup communication equipment.

[0074] Based on this, the embodiment of the present application provides a communication status monitoring and management method for power communication, which uses a first communicator and a second communicator for intelligent power communication, that is, when the first communicator is connected to the main circuit for power communication, first obtain the communication status data of the first communicator, the communication status data includes the power data read and write rate value and the power data read and write accuracy value; then input the communication status data of the first communicator into the communication status monitoring and evaluation unit to obtain the communication efficiency characterization value of the first communicator; when the communication efficiency characterization value of the first communicator is less than or equal to the efficiency threshold, switch the first communicator to the second communicator so that the second communicator is connected to the main circuit for power communication; in the process of power communication, judge the load conditions of the first communicator and the second communicator in real time, and judge the load difference between the first communicator and the second communicator; when the first communicator is not overloaded, and the load difference between the second communicator and the first communicator is greater than or equal to the preset value, re-switching the communicator to perform power communication through the first communicator. When both the first communicator and the second communicator are overloaded, a load balancing strategy of periodic switching is adopted for power communication. In this way, the performance status, load conditions and actual needs of the power grid of the communicator are comprehensively considered, and the communication status data of the communicator is monitored and evaluated in real time to dynamically adjust the usage status of the communicator to achieve the optimal configuration and efficient utilization of power communication resources.
