[0057] The present application is described more clearly below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the effects of the present application, but are not intended to limit the present application in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present application.

[0062] In addition, the “plurality” mentioned in the embodiments of the present application should be interpreted as two or more.

[0063] With the idea of ​​being able to quickly and accurately determine the operating status of the energy management system, based on a large amount of experimental data obtained by the inventor, the inventor found that when data cannot be collected normally and in a timely manner, or a large amount of abnormal energy consumption data always appears, or the operation and maintenance personnel handle it in a timely manner, the management of the energy management system will often be abnormal in the future. Therefore, the normal and timely collection of data in the energy management system, high data quality, and timely processing of system operation and maintenance work orders are important foundations for the normal operation of the energy management system. Therefore, it is possible to consider the three aspects of communication quality, energy consumption quality, and operation and maintenance quality. According to the communication quality between the energy management system and each device and subsystem, the abnormal energy consumption data in the energy consumption data, and the processing of the operation and maintenance work order, the quality parameter values ​​corresponding to the communication quality, energy consumption quality, and operation and maintenance quality are determined, and then the system quality parameter values ​​are obtained. After that, the operating status of the energy management system is determined according to the system quality parameters.

[0064] Figure 1 Schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, the application scenario includes an energy management system, and various devices and subsystems respectively connected to the energy management system for communication.

[0065] Among them, each device is a data acquisition device such as a sensor, an intelligent meter, and a collection terminal. Each device can directly send the collected data related to power supply, water supply, heating, cooling, and gas supply to the energy management system. Each subsystem is connected to the collection device, and the collection device sends the collected data related to power supply, water supply, heating, cooling, and gas supply to the corresponding subsystem. The subsystem processes the received data and sends the processed data to the energy management system. For example, the subsystem can be a photovoltaic subsystem, a charging pile subsystem, and a lighting system.

[0066] The energy management system obtains energy consumption data sent by at least one device and at least one subsystem, determines the communication quality parameter value based on the communication quality between each device and each subsystem, determines the energy consumption quality parameter value based on abnormal energy consumption data in the energy consumption data, and determines the operation and maintenance quality parameter value based on the processing of operation and maintenance work orders in the energy management system. Thereafter, the system quality parameter value of the energy management system is obtained according to the communication quality parameter value, the energy consumption quality parameter value and the operation and maintenance quality parameter value, and the operating status of the energy management system is determined according to the system quality parameter value.

[0067] In addition, the energy management system may include a display screen, and the obtained communication quality parameter values, energy consumption quality parameter values, operation and maintenance quality parameter values, and system quality parameter values ​​may be displayed on the display screen.

[0068] Figure 2FIG. 1 is a flow chart of a state monitoring method of an energy management system provided by an embodiment of the present application. Figure 2 As shown, the method in the embodiment of the present application is applied to an energy management system. The above method may include:

[0069] Step 201: Determine a communication quality parameter value based on the communication quality between the energy management system and each device and each subsystem.

[0070] In some embodiments, when determining the communication quality parameter value, steps A1 to A3 may be included.

[0071] A1. Send a first request message to each device, determine the device communication result based on the first response result of each device in response to the first request message, send a second request message to each subsystem, and determine the subsystem communication result based on the second response result of each subsystem in response to the second request message.

[0072] A2. Obtain the first generation time of each unprocessed alarm information in the energy management system within a preset time period, and determine the alarm information processing result according to the first generation time.

[0073] A3. Determine the communication quality parameter value based on the equipment communication results, subsystem communication results and alarm information processing results.

[0074] Optionally, the device communication result, the subsystem communication result and the alarm information processing result all include normal and abnormal. The first response result and the second response result all include received response and not received response.

[0075] Exemplarily, when determining the device communication result and the subsystem communication result, this embodiment can determine that the device communication result is normal when the first response result of each device in response to the first request information is that a response is received, and determine that the device communication result is abnormal when the first response result of any device in response to the first request information is that no response is received.

[0076] Similarly, when the second response result of each subsystem in response to the second request information is that a response is received, the subsystem communication result is determined to be normal; when the second response result of any subsystem in response to the second request information is that no response is received, the subsystem communication result is determined to be abnormal.

[0077] For each device, the energy management system sends a first request message to the device. If the response message of the device is received within the set time period, the first response result is that the response is received, and it is determined that the communication between the energy management system and the device is normal. Otherwise, the first response result is that the response is not received, and it is determined that the communication between the energy management system and the device is interrupted, and the device is a communication abnormal device. When there is a communication abnormal device, the communication result of the device is determined to be abnormal.

[0078] Similarly, for each subsystem, the energy management system sends a second request message to the subsystem. If the response message of the subsystem is received within the set time period, the second response result is that the response is received, and it is determined that the communication between the energy management system and the subsystem is normal. Otherwise, the second response result is that the response is not received, and it is determined that the communication between the energy management system and the subsystem is interrupted, and the subsystem is a communication abnormal subsystem. When there is a communication abnormal subsystem, the communication result of the subsystem is determined to be abnormal.

[0079] Optionally, the alarm information indicates the device and subsystem whose communication is interrupted, as well as other abnormal information related to the device and / or subsystem. In this embodiment, when determining the alarm information processing result, when the difference between the current time and the first generation time of each unprocessed alarm information is less than a first preset time difference, the alarm information processing result is determined to be normal; when the difference between the current time and the first generation time of any unprocessed alarm information is greater than or equal to the first preset time difference, the alarm information processing result is determined to be abnormal.

[0080] In this embodiment, if the difference between the current time and the first generation time of the unprocessed alarm information is greater than or equal to the first preset time difference, it means that the alarm information has not been processed in time and is a timeout alarm information. If there is a timeout alarm information in the unprocessed alarm information within the preset time period, it is determined that the alarm information processing result is abnormal.

[0081] Afterwards, when determining the communication quality parameter value, when the device communication result, the subsystem communication result, and the alarm information processing result are all normal, the communication quality parameter value may be determined to be a first value. When one of the device communication result, the subsystem communication result, and the alarm information processing result is abnormal, the communication quality parameter value may be determined to be a second value. When two of the device communication result, the subsystem communication result, and the alarm information processing result are abnormal, the communication quality parameter value may be determined to be a third value; when the device communication result, the subsystem communication result, and the alarm information processing result are all abnormal, the communication quality parameter value may be determined to be a fourth value.

[0082] Among them, the fourth value is less than the third value, the third value is less than the second value, and the second value is less than the first value. For example, the first value is 100, the second value is 60, the third value is 30, and the fourth value is 0. Among the three items of communication results, subsystem communication results, and alarm information processing, when all are normal, the communication quality parameter value is 100, when any one is abnormal, the communication quality parameter value is 60, when any two are abnormal, the communication quality parameter value is 30, and when all are abnormal, the communication quality parameter value is 0. Of course, the correspondence between the device communication results, subsystem communication results, and alarm information processing results and the communication quality parameter values ​​can also be set according to user needs and the actual operating status of the energy management system.

[0083] Optionally, the communication quality parameter value is displayed, and if the device communication result is abnormal, the communication abnormal device is displayed, if the subsystem communication result is abnormal, the communication abnormal subsystem is displayed, and if the alarm information processing result is abnormal, the timeout alarm information is displayed. This allows users to quickly locate the problem and facilitate subsequent inspection and maintenance.

[0084] Step 202: Determine the energy consumption quality parameter value according to the abnormal energy consumption data in the energy consumption data.

[0085] In some embodiments, when determining the energy consumption quality parameter value, for each energy consumption data within a preset time period, if the energy consumption data is a null value, the difference between the value of the energy consumption data and the value of the corresponding energy consumption data at the previous time is less than 0, and the difference between the value of the energy consumption data and the value of the corresponding energy consumption data at the previous time is greater than a preset value difference, at least one of the following is met, then the energy consumption data is determined to be abnormal energy consumption data. Thereafter, based on the number of all abnormal energy consumption data, the energy consumption quality parameter value is determined, and the abnormal energy consumption data is displayed.

[0086] In this embodiment, for each energy consumption data, if the energy consumption data is a null value, it means that the energy consumption data has not been obtained and a missing value occurs. The difference between the value of the energy consumption data and the value of the corresponding energy consumption data at the previous time is the energy consumption consumed in the time period between the collection time of the energy consumption data and the previous time, and should be a non-negative value. For example, the collection time of the energy consumption data is 10:05, and the previous time is 10:00, then the difference is the energy consumption between 10:00 and 10:05. Therefore, if the above difference is a negative value, it indicates that the energy consumption data is abnormal. If the above difference exceeds the preset numerical difference, that is, the energy consumption suddenly increases, it also indicates that the energy consumption data is abnormal and is abnormal energy consumption data.

[0087] Afterwards, the energy consumption quality parameter value is determined according to the number of all abnormal energy consumption data. The more abnormal energy consumption data there are, the worse the quality of the energy consumption data obtained by the energy management system is, the worse the energy consumption quality is, and the smaller the corresponding energy consumption quality parameter value is. For example, the number of abnormal energy consumption data is set to 0, and the energy consumption quality parameter value is 100; the number of abnormal energy consumption data is less than or equal to 100, and the energy consumption quality parameter value is 90; the number of abnormal energy consumption data is greater than 100 and less than or equal to 300, and the energy consumption quality parameter value is 80; the number of abnormal energy consumption data is greater than 300 and less than or equal to 500, and the energy consumption quality parameter value is 70; the number of abnormal energy consumption data is greater than 500 and less than or equal to 1000, and the energy consumption quality parameter value is 60; the number of abnormal energy consumption data is greater than 1000, and the energy consumption quality parameter value is 30. Of course, the corresponding relationship between the number of abnormal energy consumption data and the energy consumption quality parameter value can also be set according to user needs and the actual operation status of the energy management system.

[0088] Optionally, this embodiment also displays energy consumption quality parameter values ​​and abnormal energy consumption data, so that the user can quickly locate the problem and facilitate subsequent inspection and maintenance.

[0089] Step 203: Determine the operation and maintenance quality parameter value based on the processing status of the operation and maintenance work order in the energy management system.

[0090] Exemplarily, the operation and maintenance work order may include a maintenance work order, an inspection work order, and a repair work order for each device and each subsystem.

[0091] In some embodiments, when determining the value of an operation and maintenance quality parameter, for each operation and maintenance work order that has not been processed in the energy management system within a preset time period, when the difference between the current time and the second generation time of the operation and maintenance work order is greater than or equal to the second preset time difference, the operation and maintenance work order is determined to be abnormal. Thereafter, based on the number of abnormal operation and maintenance work orders, the value of the operation and maintenance quality parameter is determined, and the abnormal operation and maintenance work orders are displayed.

[0092] In this embodiment, the difference between the current time and the second generation time of the unprocessed operation and maintenance work order is greater than or equal to the second preset time difference, indicating that the operation and maintenance work order has not been processed in time and is an abnormal operation and maintenance work order.

[0093] Afterwards, the operation and maintenance quality parameter value is determined according to the number of abnormal operation and maintenance work orders. The more the number of abnormal operation and maintenance work orders, the more operation and maintenance work orders that have timed out and not been processed in the energy management system, the worse the operation and maintenance quality, and the smaller the corresponding operation and maintenance quality parameter value. For example, the number of abnormal operation and maintenance work orders is set to 0, and the operation and maintenance quality parameter value is 100; the number of abnormal operation and maintenance work orders is less than or equal to 10, and the operation and maintenance quality parameter value is 90; the number of abnormal operation and maintenance work orders is greater than 10 and less than or equal to 30, and the operation and maintenance quality parameter value is 80; the number of abnormal operation and maintenance work orders is greater than 30 and less than or equal to 50, and the operation and maintenance quality parameter value is 70; the number of abnormal operation and maintenance work orders is greater than 50 and less than or equal to 100, and the operation and maintenance quality parameter value is 60; the number of abnormal operation and maintenance work orders is greater than 100, and the operation and maintenance quality parameter value is 30. Of course, the corresponding relationship between the number of abnormal operation and maintenance work orders and the operation and maintenance quality parameter value can also be set according to user needs and the actual operation status of the energy management system.

[0094] Optionally, this embodiment also displays operation and maintenance quality parameter values ​​and abnormal operation and maintenance work orders, so that users can quickly locate problems and facilitate subsequent inspections and repairs.

[0095] Step 204: Obtain a system quality parameter value of the energy management system according to the communication quality parameter value, the energy consumption quality parameter value and the operation and maintenance quality parameter value, and determine the operation status of the energy management system according to the system quality parameter value.

[0096] Exemplarily, this embodiment uses the weighted sum of the communication quality parameter value, the energy consumption quality parameter value and the operation and maintenance quality parameter value as the system quality parameter value of the energy management system. If the system quality parameter value is greater than or equal to the preset threshold, it is determined that the operating status of the energy management system is good, and the system quality parameter value is displayed. If the system quality parameter value is less than the preset threshold, it is determined that the operating status of the energy management system is poor, an alarm is issued and the system quality parameter value is displayed.

[0097] Optionally, the calculation formula of the system quality parameter value is: system quality parameter value = communication quality parameter value × communication weight + energy consumption quality parameter value × energy consumption weight + operation and maintenance quality parameter value × operation and maintenance weight. Among them, the sum of the communication weight, energy consumption weight and operation and maintenance weight is 1, and the specific values ​​of the above three weights can be set according to user needs. For example, if the user has higher requirements for communication quality, the communication weight value is larger, such as the communication weight, energy consumption weight and operation and maintenance weight can be 0.5, 0.2 and 0.3 respectively.

[0098] Exemplarily, after determining the system quality parameter value, if the system quality parameter value is greater than or equal to a preset threshold, it indicates that the energy management system is in good operating condition at this time, and only the system quality parameters and existing abnormal communication equipment, abnormal communication subsystems, timeout alarm information, abnormal energy consumption data, abnormal operation and maintenance work orders and other abnormal items can be displayed, as well as the communication quality parameter value, energy consumption quality parameter value and operation and maintenance quality parameter value, so that users can understand the communication, energy and operation and maintenance situations in the energy management system, and locate abnormal items in the energy management system.

[0099] If the system quality parameter is less than the preset threshold, it indicates that the energy management system is in a poor operating state, and an alarm is issued. The system quality parameter and abnormal communication equipment, abnormal communication subsystem, timeout alarm information, abnormal energy consumption data, abnormal operation and maintenance work orders and other abnormal items are displayed, as well as the communication quality parameter value, energy consumption quality parameter value and operation and maintenance quality parameter value. This allows users to promptly discover operating problems in the energy management system based on the alarm prompt, understand the communication, energy and operation and maintenance conditions in the energy management system, and quickly locate problems based on the displayed abnormal items, facilitating subsequent detection and repair of abnormal items.

[0100] The preset threshold value may be set according to user needs and the actual operation status of the energy management system. For example, the preset threshold value may be 80.

[0101] An example is, refer to Figure 3A When the user needs to determine the operating status of the energy management system, the user can click the "monitoring" icon on the display interface of the display screen of the energy management system. In response to the user clicking the "monitoring" icon, the energy management system executes the state monitoring method of the energy management system in the aforementioned embodiment to obtain the system quality parameter value and the operating status of the energy management system. The display interface may also include a progress bar. During the monitoring process, the energy management system controls the progress bar to load as the monitoring progresses, and when it is determined that the communication quality parameter value, the energy consumption quality parameter value and / or the operation and maintenance quality parameter value are not 100, that is, when the communication quality, the energy consumption quality and / or the operation and maintenance quality are abnormal, the corresponding icon on the progress bar in the display interface is lit, for example, the corresponding icon is turned red.

[0102] When the operating status of the energy management system is good, the operating status of the energy management system and the system quality parameter values ​​are displayed on the display interface. At the same time, abnormal items such as abnormal communication equipment, abnormal communication subsystems, timeout alarm information, abnormal energy consumption data, and abnormal operation and maintenance work orders are displayed, as well as communication quality parameter values, energy consumption quality parameter values, and operation and maintenance quality parameter values.

[0103] When the operating status of the energy management system is poor, an alarm prompt is issued, such as a voice alarm prompt or a flashing light alarm prompt, and the operating status of the energy management system and the system quality parameter value are displayed on the display interface. At the same time, abnormal items such as abnormal communication equipment, abnormal communication subsystems, timeout alarm information, abnormal energy consumption data and abnormal operation and maintenance work orders are displayed, as well as communication quality parameter values, energy consumption quality parameter values ​​and operation and maintenance quality parameter values.

[0104] For example, refer to Figure 3B , the display interface shows that the operating status of the energy management system is "poor" and the system quality parameter value is "60", and the communication quality parameter value, energy consumption quality parameter value and operation and maintenance quality parameter value are "30", "90" and "90" respectively. And it shows that there are 0 abnormal items in device communication, 3 abnormal items in subsystem communication, 2 abnormal items in alarm information processing, 5 abnormal items in energy consumption quality, and 7 abnormal items in operation and maintenance quality. When the user wants to view specific abnormal items, such as abnormal items in subsystem communication, he can click "Subsystem Communication: 3 Items" on the display interface. The energy management system responds to the user's click operation and displays the abnormal communication subsystem and the corresponding problems on the display interface. Reference Figure 3C The display interface shows that the subsystems with abnormal communication are: photovoltaic subsystem, charging pile subsystem and lighting subsystem, and the corresponding problem is communication interruption.

[0105] Optionally, the user can also select a monitoring period on the display interface of the energy management system. For example, if the monitoring period is selected as today's 0:00 to 12:00, the energy management system will obtain energy consumption data, operation and maintenance work orders, etc. within the monitoring period based on the above monitoring period to determine the operating status of the energy management system.

It determines the communication quality parameter value, energy consumption quality parameter value and operation and maintenance quality parameter value based on the communication quality between the energy management system and each device and each subsystem, the abnormal energy consumption data in the energy consumption data, and the processing of the operation and maintenance work order in the energy management system. Then, according to the communication quality parameter value, the energy consumption quality parameter value and the operation and maintenance quality parameter value, the system quality parameter value is obtained, and the operating state of the energy management system is determined according to the system quality parameter value, so that the operating state of the energy management system can be determined quickly, accurately and comprehensively, thereby reducing the workload of relevant personnel.
