Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial communication, in particular to a data issuing control method and device. BACKGROUND

[0002] In industrial automation, power monitoring and control and many other occasions, the cooperative work between the energy management system (for example, EMS) and the energy storage converter (for example, PCS) is increasingly critical, and stable and efficient communication between the two is the core link to realize stable operation, accurate control and efficient management of the system. The timeliness, accuracy and rationality of data transmission directly affect the performance of the entire system.

[0003] Because RS485 communication has the advantages of strong anti-interference ability, long transmission distance and low cost, it is widely used in data interaction between EMS and PCS. However, RS485 adopts a half-duplex communication mode, which leads to the fact that data can only be transmitted in one direction at the same time. When the energy management system performs data writing operation, the communication line is occupied and cannot simultaneously perform data reading.

[0004] However, for the interaction between the energy management system and the energy storage converter, real-time transmission of data such as power, current and voltage is crucial. Because the energy management system cannot read the latest state parameters at the same time when writing data, the data obtained by the energy management system often lags behind the actual situation. During the continuous data writing process, the system will use old state data and cannot reflect the real-time running state of the device in time, resulting in reduced control accuracy of the system on the device. In some scenarios where data real-time performance is extremely high, control errors may even occur, affecting the safe and stable operation of the system. Therefore, how to effectively control data writing and realize reasonable writing of data in half-duplex communication has an important influence on improving the interaction performance between the energy management system and the energy storage converter.

[0021] The present application will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application. It should be noted that the following detailed description is exemplary and is intended to provide further description of the present application.

[0022] To clearly describe the specific process of the technical solution of the present application, the following embodiments take the half-duplex communication data interaction process between the energy management system and the energy storage converter as an example for illustration, but this cannot limit the specific application scenarios of the present application. The energy management system is a kind of management system of electrical equipment and power consumption link, which realizes the safe operation, energy saving and operation and maintenance management of electrical system through monitoring, analysis, optimization and maintenance. The energy management system does not directly intervene in the real-time transmission or conversion of power, but makes management decisions through data-driven management. The energy storage converter is a control type system around power flow, which directly controls the power charging and discharging process through real-time adjustment, instruction execution and fault protection. Generally, the energy storage converter directly acts on the power equipment and is the operation center of the power system.

[0023] In the present application, the energy management system and the energy storage converter preferably use RS485 devices for data interaction. Since it uses half-duplex communication mode, it means that at the same time, data can only be transmitted in one direction, so when the energy management system is transmitting data for a long time, the communication line is occupied and cannot read data at the same time, which leads to the data obtained by the energy management system often lags behind the actual situation.

[0024] Embodiment 1 Specifically, as shown in Figure 1 The embodiment 1 discloses a data transmission control method, and the execution subject includes an energy management system. It can be understood that in other embodiments, the execution subject can also be other modules or devices with data transmission and reception functions other than the energy management system, such as energy storage converters or battery management systems, etc. The method includes the following steps: First, obtain the second data determined based on the first data.

[0025] In the embodiment 1, the first data refers to one or more of the voltage, power, current and relay state parameters collected by the energy management system. According to different data types, the energy management system can collect discrete data of corresponding data types, of course, other data types collected by the energy management system can also be applied in this scheme, such as temperature, air pressure, etc. For example, in the embodiment 1, the energy storage application scenario is taken as an example, at this time, the first data can also include: battery body state data, including single battery voltage, battery pack total voltage, single battery temperature, etc.; energy storage converter operation data, including converter input or output voltage, input or output current, active power, reactive power, conversion efficiency, switch state and heat dissipation system temperature, etc.

[0026] Further, the energy management system in this embodiment 1 will process and analyze the collected first data according to the preset algorithm, and then obtain the second data to be issued. For example, the preset algorithm can adopt one or more of threshold following control strategy, fixed curve tracking strategy, model optimization control strategy, machine learning prediction strategy or collaborative control strategy, and the energy management system can correspondingly obtain the second data based on these strategies. In this embodiment 1, the second data includes one or more of voltage, power, current and relay control parameters to be issued by the energy management system. The second data is the control data generated by the energy management system according to the first data, and the control data is issued to the energy storage converter to implement operation adjustment. For example, still taking the energy storage application scenario as an example in this embodiment 1, the second data can include: battery body control data, including battery charge and discharge rate, equalization circuit start instruction, cooling start and stop instruction, etc.; energy storage converter operation data, including compensation power, converter start and stop or mode switching instruction, fan speed, etc.

[0027] As a preferred embodiment, in the process of determining the second data by the first data in this embodiment 1, the energy management system can determine the collection time interval of the corresponding data type according to the type of the first data. For example, in this embodiment 1, the power collected by the energy management system requires high real-time performance because the energy management system needs to frequently adjust the equipment output power, so the collection time interval of the power data can be set to a short time, for example, 500 ms, and the energy management system will collect power data every 500 ms. For data types with low real-time requirements, such as voltage and relay state parameters, the collection time interval of the corresponding data can be set to a longer time to reduce the data volume of the energy management system.

[0028] After determining the time collection interval, the corresponding first data can be collected in sequence according to the time collection interval, and a time stamp can be added to the first data. Then, by sorting the first data with time stamps in chronological order, the energy management system can process the first data according to the pre-built algorithm to obtain the corresponding second data, so as to ensure that the issued data and the collected data in the energy management system are time-sequential, which is convenient for subsequent tracing of the basis for generating control instructions, and can further improve the accuracy of data interaction and control through historical data optimization control strategy.

[0029] Then, the second data and the third data in this embodiment 1 will be compared to obtain a first difference index. The first difference index represents the difference between the second data and the third data, which is mainly used to reduce the frequent issuance of the second data, especially for the case where the second data changes little before and after, which can reduce the frequency of second data issuance and avoid occupying the communication link. The third data belongs to the last determined second data that satisfies the first difference index greater than the first preset index threshold, for example, taking the output power of the energy storage system in the energy storage application scenario as an example, when the energy management system generates corresponding second data based on the first data at the previous time greater than the first preset index threshold at the previous time, it is determined that the second data needs to be issued. At this time, the energy management system will mark the second data determined to be issued at the previous time as the third data and store it in the dedicated non-volatile cache area.

[0030] As a preferred embodiment, the first difference index in this embodiment 1 can be selected as the first difference value. When the energy management system generates new second data, the last determined second data, i.e. the third data, is retrieved, and then the absolute value of the two is calculated by the difference algorithm, i.e. the first difference value = |third data-second data|. The first difference value can be used to know the change fluctuation of the second data generated at the previous and next time. In the case where the change fluctuation of the second data is small, the newly generated second data will not have a significant impact on the device even if it is issued. Based on the purpose of reducing invalid data transmission, the newly generated second data does not need to be issued at this time. Conversely, for the case where the change fluctuation of the second data is small, the newly generated second data will have a significant impact on the device and needs to be issued in time.

[0031] As another preferred embodiment, the first difference index in this embodiment 1 can also be selected as the first ratio, i.e. the first ratio = second data / third data. The first ratio can also intuitively reflect the change fluctuation of the second data generated at the previous and next time, and this method can eliminate the data magnitude interference, effectively reduce invalid data issuance, and improve the stability of data interaction. Of course, the first difference index in this embodiment 1 can also use the absolute deviation rate, i.e. the absolute deviation rate = |third data-second data| / second data x 100%. Of course, the above-mentioned multiple indicators can also be used, and the specific selection is selected according to the application occasion and data requirements. It should be noted that the above-mentioned first difference value, first ratio and absolute deviation rate are only typical application examples, and the selection range of the first difference index is not limited, and other quantifiable data difference indicators can also be applied to this application.

[0032] In this embodiment 1, by comparing a first difference index with a first preset index threshold, it is possible to preliminarily determine whether newly generated second data is valid. If the first difference index is greater than the first preset index threshold, it indicates that the newly generated second data has changed significantly compared to the previous second data, and should be allowed to be sent. Conversely, if the first difference index is less than or equal to the first preset index threshold, it indicates that the newly generated second data has changed only slightly compared to the previous second data, and has no impact on the device state; therefore, it is invalid data and does not need to be placed in the sending queue for transmission. Of course, to ensure that the comparison results of the second data generated at different times match the actual operating state of the device, the second data determined to be allowed for transmission can be saved as third data in real time. This mechanism effectively avoids mechanical wear caused by the system frequently receiving minor adjustment commands, and also prevents the repeated transmission of data with minor changes from occupying the communication path.

[0033] By reducing the frequency of invalid data transmission, the communication lines can dedicate more time to data reading. This not only ensures timely updates of status data such as power, current, and voltage, providing a solid foundation for system control decisions, but also provides more bandwidth for data transmission, enhancing the stability and reliability of the entire communication system. Especially in applications with high real-time data requirements, it effectively avoids control errors caused by data lag, reduces the probability of equipment failures and safety accidents, and ensures the safe and stable operation of the entire system.

[0034] Example 2: More specifically, this embodiment 2 also discloses a data distribution control method, which further adds a distribution verification process based on the method of embodiment 1.

[0035] Specifically, such as Figure 2As shown, when the first difference index meets the first preset index threshold, the second data that meets the condition is taken as the data to be written, and the data to be written is placed in the distribution queue for distribution. At this time, the data to be written is further compared with the first dataset to obtain the second difference index set. It should be explained that the first dataset is a collection of first data acquired within a preset time range. For example, in this embodiment 2, the data to be written at time t is taken as an example. In order to determine whether the current data to be written has changed significantly within 3 seconds compared with the first data collected in real time, the first dataset can be selected as the first data in the range of [t, t+3]. The second difference index set is a collection of second difference indices obtained by comparing the data to be written with each first data in the first dataset. The second difference index represents the degree of difference between the first data and the data to be written. By analyzing all the second difference indicators in the second difference indicator set, it can be determined whether the target load changes stably with the data to be written at time t within a preset time range after the data to be written at time t is sent. If the difference between the first data from the target load and the data to be written at time t within the preset time range is less than or equal to the second preset indicator threshold, it indicates that the target load has successfully changed with the data to be written at time t, that is, the data to be written at time t has been successfully sent. If the difference between the first data from the target load and the data to be written at time t within the preset time range is greater than the second preset indicator threshold, it indicates that the target load has not changed with the data to be written at time t, that is, the data to be written at time t has failed to be sent, and it should be sent again in a timely manner.

[0036] This data delivery verification process compares the data to be written with the first data read in real time to determine whether the data to be written has been successfully delivered to the target load. It can promptly detect and correct data delivery failures, ensuring the system can stably and accurately acquire the data to be written. Furthermore, this verification process, combined with that in Example 1, avoids erroneous writes caused by momentary fluctuations, reduces frequent changes in device status due to invalid writes, extends device lifespan, and lowers maintenance costs. Simultaneously, by comparing the data to be written with the first data read in real time within a preset time range, it effectively avoids misjudgments caused by momentary load fluctuations, preventing the erroneous re-delivery of the data to be written, further reducing the risk of data erroneous writing.

[0037] Similarly, in order to maintain consistency with the first difference index, the second difference index in this embodiment 2 can also be a second difference value or a second ratio value, or a combination of both.

[0038] In this embodiment 2, if all the second difference indicators are greater than the second preset indicator threshold, it indicates that the change in the second data compared to the real-time collected first data has continued for a preset time. This means that the data to be written has not been sent to the target load, i.e., the sending has failed. At this time, the data to be written will be placed back into the sending queue for a second sending. When all the second difference indicators in the second difference indicator set are less than or equal to the second preset indicator threshold, it indicates that the data to be written has been successfully sent to the target load, and the target load has successfully changed accordingly, prompting the next data to be written to be judged. Through the above steps, the interference of short-term device status fluctuations on the sending judgment can be avoided, which may cause the data to be written to be sent incorrectly a second time, further improving the accuracy and stability of data writing.

[0039] Example 3: This embodiment 3 also discloses a data transmission control method. Compared with the solution in embodiment 2, this solution further determines that due to the influence of instantaneous fluctuations in equipment, sensors, and other factors, there may be misjudgments. For example, due to instantaneous factors such as sensor noise and instantaneous load fluctuations in equipment, the collected first data may fluctuate briefly. In this case, some second difference indicators in the second difference indicator set may be less than or equal to the second preset indicator threshold, while some second difference indicators may be greater than the second preset indicator threshold. In this case, further transmission determination is required to improve the decision-making accuracy of the transmission action.

[0040] Specifically, such as Figure 2 As shown, the decision-making process is as follows: First, a third set of difference indicators is obtained based on the second set of difference indicators. This third set of difference indicators is the set of second difference indicators in the second set of difference indicators that are less than or equal to the second preset threshold. This process filters out the second difference indicators in the original second set of difference indicators that are less than or equal to the second preset threshold, facilitating subsequent statistical processes.

[0041] Subsequently, a first indicator is determined based on the third set of difference indicators. The first indicator is the total duration of the second difference indicators in the third set of difference indicators that are less than or equal to the second preset indicator threshold.

[0042] If the first indicator is less than or equal to the third preset indicator threshold, it indicates that the target load has not changed with the data to be written within the preset time range, that is, the data to be written has not been successfully sent to the target load. At this time, it can be determined that the data to be written has failed to be sent, and the data to be written is put back into the sending queue.

[0043] If the first indicator is greater than the third preset indicator threshold, it indicates that within the preset time range, the target load changes with the data to be written, and the data to be written has been successfully sent to the target load. At this time, it is determined that the data to be written has been successfully sent, and the next data to be written is judged.

[0044] This data delivery determination process can further accurately determine the secondary delivery of the data to be written. By evaluating the load response time, the accuracy of the delivery result determination is further improved. It can avoid the incorrect delivery of the data to be written due to fluctuations in the target load (i.e., fluctuations in the first data), making the data delivery control more in line with the actual operating scenario and further enhancing the accuracy and stability of data writing.

[0045] Example 4: This embodiment 4 also discloses a data delivery control method, which adds a delivery queue clearing step compared to the solution in embodiment 1. For example... Figure 3 As shown, the queue clearing step includes: First, the second indicator is obtained, which is the number of data items waiting to be written in the distribution queue. When the equipment load is unstable and fluctuates frequently, a large amount of data items may be placed in the distribution queue. If the distribution queue distributes the data items in the order of the queue, the communication link will be occupied for a long time due to the distribution action. The energy management system will not be able to collect the first data in time, and therefore will not be able to generate the corresponding second data in time, which can easily lead to equipment control errors.

[0046] When the second indicator exceeds the fourth preset indicator threshold, there is a large amount of data to be written in the distribution queue. If the data is distributed sequentially according to the queue order, the status of the corresponding device will change frequently in a short period of time, resulting in decreased device stability. To improve device stability, in this embodiment 4, the fourth data is obtained by filtering the data to be written in the distribution queue according to the distribution time order. This fourth data is the latest data to be written in the distribution queue.

[0047] After selecting the fourth data point, the write operation is executed on it, while other data to be written that precedes the fourth data in the write time sequence are deleted. This step addresses situations where the device load is unstable. When there is a large amount of data to be written in the write queue, the device is controlled using the most recently written data, bypassing the device load fluctuation process. This avoids link congestion caused by frequent data writes, ensures timely data updates, reduces the amount of data to be written, ensures the real-time performance and accuracy of control commands, and guarantees stable device operation.

[0048] In addition, such as Figure 4 As shown, this application also discloses a data distribution control device, the device comprising: The data acquisition module is used to acquire second data determined based on the first data; the second data is obtained by processing the first data using a preset algorithm; The first comparison module is used to compare the second data and the third data to obtain a first difference index; the first difference index includes a first difference value and / or a first ratio value, and the third data is the second data determined in the previous time that satisfies the first difference index being greater than a first preset index threshold. The action module is used to take the second data with a first difference index greater than a first preset index threshold as the data to be written and put the data to be written into the action queue.
