[0022] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of this application. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0024] Figure 2 A schematic structural diagram of a power supply box provided in an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0026] At present, in order to temporarily supply power to faulty power equipment, it is necessary to select a power box for temporary power supply to the power equipment from multiple power boxes so as to repair the power equipment. In the actual working process, each power box may have different parameters, and different power boxes are more suitable for specific power equipment. At present, when selecting a power box, relevant staff need to select a suitable power box for the power equipment based on their work experience to provide temporary power supply for it. However, if the relevant staff is not experienced enough, they may select a power box that is not suitable for the power equipment, resulting in poor power supply effect when the power equipment is powered by the above power box. Therefore, the existing power box selection method cannot guarantee the matching degree between the selected power box and the power equipment.

[0027] In one embodiment, Figure 1 As shown, a power box management system is provided, and the system is used to manage the power box 120 in the power plant as an example for explanation, wherein the power box 120 is used to provide temporary power supply to the power equipment (not shown in the figure) in the power plant, and the power equipment may be generators, power system controllers, transformers and other equipment.

[0028] Furthermore, the electrical equipment has multiple preset power box usage conditions, wherein the power box usage conditions may include voltage level requirements for the power supply voltage that the power box can provide, size requirements for the power box, number requirements for the power output interfaces of the power box, and standard requirements for the power output interfaces of the power box.

[0029] Here, for the power equipment in the power plant, the space where it is located may be small, and it may be difficult to power it if a larger power box is used; further, the power equipment may also require a small voltage range of the power supply voltage. If a power box that outputs a power supply voltage of an inappropriate voltage level is used, an additional transformer is required for voltage conversion, which affects the power supply efficiency of the power box to the power equipment; further, if the power equipment only needs a separate power output interface to power it, if a power box with too many power output interfaces is used, the volume and weight of the power box will be too large, which will cause an additional burden on temporary power supply work; further, if the power supply interface standard of the power equipment is relatively special, if a universal power output interface is used to power the power equipment, an additional carrying interface conversion device is required, which affects the power supply efficiency of the power box to the power equipment. Further, the type and quantity of the power box usage conditions can be determined according to the actual situation, and are not limited here. Here, the power box usage conditions of each power equipment in the power plant are stored in a local database.

[0030] Further, such as Figure 1 As shown, the management system of the power box includes a system controller 110 and multiple power boxes 120, wherein the system controller 110 can be a computer device such as a server, and the power box 120 has preset power box parameter information. Here, the power box parameter information of the power box 120 can be composed of multiple pieces of information, which can include the voltage level of the power supply voltage that the power box can provide, the size of the power box, the number of power output interfaces of the power box, and the power output interface standard of the power box, etc., which are not limited here. Here, the power box parameter information of each power box 120 in the power plant is stored in a local database.

[0031] Furthermore, a wireless communication unit may be provided in the power box 120 and the system controller 110, for establishing wireless communication between the power box 120 and the system controller 110, where the wireless communication unit may be a Lora communication unit. Furthermore, the system controller 110 establishes a communication connection with a remote host computer (not shown in the figure), where the host computer may be a computer terminal or server used by relevant management personnel, and relevant personnel may control the management work of the power box 120 based on the host computer.

[0032] Furthermore, the system controller 110 is configured to perform the following processing:

[0033] First, the system controller 110 determines the power equipment that needs temporary power supply, and obtains the use conditions of the multiple power boxes of the power equipment. Specifically, when the power equipment needs to be repaired and the power box 120 needs to be used for temporary power supply, the relevant maintenance personnel can submit a maintenance application at the host computer, and the system controller 110 receives the maintenance application and sends the maintenance application to the audit host computer used by the relevant auditors, wherein the application content needs to select the factory area, area, and power equipment that needs temporary power supply, and fill in the fault phenomenon information of the power equipment; further, the relevant auditor reviews the maintenance application, approves the use of the equipment after the review is passed, and sends the approval information to the system controller 110. The system controller 110 responds to the approval information, determines the power equipment that needs temporary power supply according to the maintenance application, and obtains the multiple power box use conditions that are pre-mapped and stored with the identification information of the power equipment from the local database.

[0034] Then, the power box demand coefficient preset for the power equipment is obtained, and the standard lower limit quantity corresponding to the power equipment is determined based on the power box demand coefficient; wherein the power box demand coefficient is used to characterize the weight of the power equipment, and each power box demand coefficient can correspond to a specific standard lower limit quantity, for example, 0% can correspond to the standard lower limit quantity "0", 25% can correspond to the standard lower limit quantity "1", 50% can correspond to the standard lower limit quantity requirement "2", 75% can correspond to the standard lower limit quantity "3", and 100% can correspond to the standard lower limit quantity "4", and the power box demand coefficient corresponding to each power equipment can be predetermined based on actual conditions and stored in a local database. Here, the power box demand coefficient of the power equipment is used to characterize the power equipment's requirements for the parameters of the power box 120. If the power equipment has high requirements for the parameters of the power box 120, and more power box usage conditions must be met to temporarily power the power equipment, a higher power box demand coefficient can be preset for the power equipment. If the power equipment has low requirements for the parameters of the power box 120, a universal power box 120 can meet the power supply requirements of the power equipment, and a lower power box demand coefficient can be preset for the power equipment.

[0035] Further, determine whether the power box parameter information of each of the power boxes 120 satisfies the power box usage conditions that are greater than or equal to the standard lower limit number. Here, each power box usage condition of the power equipment can have a preset priority, and multiple power box usage conditions are arranged in order of priority from high to low to obtain a condition queue. In the actual working process, the power box parameter information can be adapted to each power box usage condition in the condition queue in order of priority from high to low to determine whether the power box parameter information satisfies the power box usage condition in the condition queue. Among them, when adapting, all the power box parameter information of the power box 120 can be matched with the power box usage conditions in turn to determine whether one of the power box parameter information meets the power box usage conditions.

[0036] As an example, if a power box usage condition is a voltage level requirement, which requires that the voltage level of the power supply voltage that the power box 120 can provide is 12 volts, and the voltage level of the power supply voltage that the power box can provide in the power box parameter information of the power box 120 is 12V, then the power box parameter information of the power box 120 meets the power box usage condition; conversely, if a power box usage condition is a voltage level requirement, which requires that the voltage level of the power supply voltage that the power box 120 can provide is 12 volts, and the voltage level of the power supply voltage that the power box can provide in the power box parameter information of the power box 120 is 24V, then the power box parameter information of the power box 120 does not meet the power box usage condition.

[0037] Furthermore, when the power box parameter information cannot satisfy a power box usage condition in the condition queue, the amount of information of the power box usage condition satisfied by the power box parameter information at this time is determined, and it is determined whether the amount of information is greater than or equal to the standard lower limit. When the amount of information is greater than or equal to the standard lower limit, it is determined that the power box parameter information satisfies the power box usage condition that is greater than or equal to the standard lower limit. Conversely, when the amount of information is less than the standard lower limit, it is determined that the power box parameter information does not satisfy the power box usage condition that is greater than or equal to the standard lower limit.

[0038] Finally, when the power box parameter information of the power box 120 satisfies the power box usage condition that is greater than or equal to the standard lower limit number, the power box 120 is determined as a recommended power box. Subsequently, the identification information used to characterize the identity of the recommended power box can be sent to the host computer, so that the relevant staff can determine the recommended power box from the host computer to obtain the recommended power box for temporary power supply to the power equipment.

[0039] The management system of the power box provided in this embodiment can obtain multiple power box usage conditions of the power equipment that needs to be temporarily powered, and the power box demand coefficient of the power equipment, wherein the power box demand coefficient is used to determine the lower limit number of power box usage conditions that the power box that provides temporary power to the power equipment needs to meet. Here, if the power equipment has a high demand for the parameters of the power box, a higher power box demand coefficient can be preset for the power equipment, and if the power equipment has a low demand for the parameters of the power box, a lower power box demand coefficient can be preset for the power equipment. Further, the number of power box usage conditions that can be satisfied by the power box parameter information of each power box is determined. If the number of power box usage conditions that can be satisfied by the power box parameter information of a certain power box is higher than the lower limit number determined by the power box demand coefficient, the power box is determined as a recommended power box. At this time, the relevant staff can select the recommended power box to better adapt to the power equipment and achieve better power supply to the power equipment, thereby significantly improving the adaptability of the selected power box and the power equipment, thereby ensuring the matching degree of the selected power box and the power equipment.

[0040] In an optional embodiment, the plurality of power box usage conditions include a first preset number of power box model conditions and a second preset number of power box history record conditions; wherein the power box model condition may be the area condition where the power box is located, the wireless communication status condition between the power box and the system controller, the model condition of the power box, and the power box interface condition of the power box, etc., and the type and number of the power box model conditions may be determined according to actual conditions. Here, the area condition is used to specify the setting area of ​​the power box in the power plant area, wherein the power plant area may include multiple areas, each area is provided with at least one power device and a power box, and the system controller records the area where each power box is located, and the area condition may require that the power box be set in the same area as the power device that needs to be temporarily powered or in other specific areas to facilitate the extraction and operation of relevant staff; further, the wireless communication status condition is used to specify the offline or online status of the power box, and the wireless communication status condition may require that the power box must be in an online state to ensure the availability of the power box; further, the model condition is used to specify the model of the power box; further, the power box interface condition is used to specify the power output interface that the power box must have.

[0041] Furthermore, the power supply box history record condition may include a fault content condition corresponding to the power supply box, a maintenance type condition corresponding to the power supply box, a maintenance equipment condition corresponding to the power supply box, and a maintenance history record condition corresponding to the power supply box, etc.; wherein, the fault content condition may require the fault phenomenon information of the power equipment that was temporarily powered by the power box in the previous use, that is, the power box is required to have temporarily powered the power equipment with specific fault content, and here, the fault content is the fault description information of the power equipment in the maintenance application submitted by the relevant staff when applying for the use of the power box; further, the maintenance type condition may require the fault type of the power equipment that was temporarily powered by the power box in the previous use, and here, the fault type may include mechanical failure or circuit board abnormal failure, etc., that is, the maintenance type condition may require the power box to temporarily power the power equipment with mechanical failure, or require the power box to temporarily power the power equipment with circuit board abnormal failure.

[0042] Furthermore, the equipment maintenance condition may require the power box to provide temporary power to the power equipment in the previous use, and the fault location may include circuit board failure, generator rotor failure, power supply cable failure, control board failure, etc., that is, the equipment maintenance condition may require the power box to provide temporary power to the power equipment with a specific fault location, such as requiring the power box to provide temporary power to the power equipment with a control board failure. Furthermore, the maintenance history record condition is used to require the number of times the power box has provided temporary power, such as requiring the power box to provide temporary power for more than 5 times.

[0043] Further, the power box parameter information of the power box includes the power box model information and the power box usage record information, wherein the power box model information may include the area information where the power box is set, the wireless communication status information between the power box and the system controller, the power box model information and the power box interface information of the power box, etc. The type and quantity of the power box model information can be determined according to the actual situation. Here, the area information is used to describe the setting area of ​​the power box in the power plant; further, the wireless communication status information is used to specify the offline or online status of the power box. When the power box is offline, the wireless communication status information is offline, and when the power box is online, the wireless communication status information is online; further, the model information is used to record the model of the power box; further, the power box interface information is used to record the power output interface of the power box.

[0044] Furthermore, the power box usage record information may include fault content information corresponding to the power box, maintenance type information corresponding to the power box, maintenance equipment information corresponding to the power box, and maintenance history record information corresponding to the power box, etc.; wherein, the fault content information may record the fault content that occurred in the power equipment that was temporarily powered by the power box during previous use. Here, the fault content is the fault description information of the power equipment in the maintenance application submitted by the relevant staff when applying for the use of the power box. After the temporary power supply task through the power box is completed, the fault description information is added to the fault content information of the power box; further, the maintenance type information may be the fault type that occurred in the power equipment that was temporarily powered by the power box during previous use. Here, the fault type may include mechanical failure or circuit board abnormality failure, etc., that is, the maintenance type information may record the fault type of the power equipment that the power box has provided temporary power supply to. After the relevant staff has performed maintenance on the faulty power equipment, they may add the fault type of the power equipment to the maintenance type information of the power box.

[0045] Furthermore, the maintenance equipment information may require the fault location of the fault that occurred in the power equipment that the power box used to provide temporary power supply in the previous use. Here, the fault location may include circuit board fault, generator rotor fault, power supply cable fault, control board fault, etc., that is, the maintenance equipment information may include the fault location of the power equipment that the power box provides temporary power supply. After the relevant staff has completed the maintenance of the faulty power equipment, they can add the fault location of the power equipment to the maintenance equipment information of the power box. Furthermore, the maintenance history record information is used to record the number of times the power box has provided temporary power supply.

[0046] Here, the power box's area information, wireless communication status information, model information, power box interface information, fault content information, maintenance type information, maintenance equipment information, and maintenance history record information can be mapped and stored with the power box's identification information. When the system controller needs to obtain the power box's parameter information, it can obtain the above power box parameter information in the database based on the power box's identification information.

[0047] Furthermore, the power box demand coefficient includes a model demand coefficient and a historical record demand coefficient; wherein the model demand coefficient is used to characterize the demand weight of the power box model information of the power equipment, and each model demand coefficient can correspond to a specific first lower limit quantity, for example, 25% can correspond to the first lower limit quantity "1", 50% can correspond to the first lower limit quantity "2", 75% can correspond to the first lower limit quantity "3", and 100% can correspond to the first lower limit quantity "4". The model demand coefficient corresponding to each power equipment can be predetermined based on actual conditions and stored in a local database.

[0048] Furthermore, the historical record demand coefficient is used to characterize the demand weight of the power box usage record information of the power equipment. Each historical record demand coefficient can correspond to a specific second lower limit number, for example, 25% can correspond to the second lower limit number "1", 50% can correspond to the second lower limit number "2", 75% can correspond to the second lower limit number "3", and 100% can correspond to the second lower limit number "4". The historical record demand coefficient corresponding to each power equipment can be predetermined based on actual conditions and stored in a local database.

[0049] Furthermore, the system controller obtains a preset power box requirement coefficient for the power equipment, and determines the standard lower limit quantity corresponding to the power equipment based on the power box requirement coefficient, including:

[0050] First, the system controller obtains the model demand factor and the historical record demand factor of the power equipment.

[0051] Then, a first lower limit quantity corresponding to the electric power equipment is determined based on the model demand coefficient, and a second lower limit quantity corresponding to the electric power equipment is determined based on the historical record demand coefficient.

[0052] Furthermore, the system controller determines whether the power box parameter information of each power box satisfies the power box usage condition that is greater than or equal to the standard lower limit number, and when the power box parameter information of the power box satisfies the power box usage condition that is greater than or equal to the standard lower limit number, the power box is determined as a recommended power box, including:

[0053] First, the system controller determines whether the power box model information of each power box satisfies the power box model condition that is greater than or equal to the first lower limit number, and determines whether the power box usage record information of each power box satisfies the power box history record condition that is greater than or equal to the second lower limit number.

[0054] Here, each power box model condition of the power equipment can have a preset priority, and multiple power box model conditions are arranged in order of priority from high to low to obtain a first condition queue. In the actual working process, the power box model information is adapted to each power box model condition in the first condition queue in order of priority from high to low to determine whether the power box model information satisfies the power box model condition in the condition queue. When the power box model information cannot satisfy a certain power box model condition in the condition queue, determine the first information quantity of the power box model condition satisfied by the power box model information at this time, and determine whether the first information quantity is greater than or equal to the first lower limit quantity. When the first information quantity is greater than or equal to the first lower limit quantity, determine that the power box model information satisfies the power box model condition greater than or equal to the first lower limit quantity. Conversely, when the first information quantity is less than the first lower limit quantity, determine that the power box model information does not satisfy the power box model condition greater than or equal to the first lower limit quantity.

[0055] Similarly, each power box history record condition of the electrical equipment can have a preset priority, and multiple power box history record conditions are arranged in order of priority from high to low to obtain a second condition queue. In the actual working process, the power box usage record information is adapted to each power box history record condition in the second condition queue in order of priority from high to low to determine whether the power box usage record information satisfies the power box history record condition in the condition queue. When the power box usage record information cannot satisfy a certain power box history record condition in the condition queue, determine the second information quantity of the power box history record condition satisfied by the power box usage record information at this time, and determine whether the second information quantity is greater than or equal to the second lower limit quantity. When the second information quantity is greater than or equal to the second lower limit quantity, determine that the power box usage record information satisfies the power box history record condition greater than or equal to the second lower limit quantity. Conversely, when the second information quantity is less than the second lower limit quantity, determine that the power box usage record information does not satisfy the power box history record condition greater than or equal to the first lower limit quantity.

[0056] Finally, when the power box model information of the power box satisfies the power box model condition that is greater than or equal to the first lower limit number, and the power box usage record information of the power box satisfies the power box history record condition that is greater than or equal to the second lower limit number, the power box is determined as the recommended power box. The embodiment provided by the present application can select a recommended power box from multiple power boxes from multiple angles, thereby improving the matching between the selected power box and the power equipment.

[0057] Furthermore, an intelligent algorithm for the power box can be added to the system controller. When the operator has a task, the system controller will initially divide the size of the power plant into multiple areas, and push the size of the power box that meets the maintenance space of the maintenance address based on the initial input data. During the use of the system, the system will record information on each use of the power box. The recorded information includes detailed information such as the plant area, area, maintenance spare parts, and maintenance content used. The system compiles maintenance records based on the above information. Furthermore, the system can also set update strategies based on actual conditions, and regularly update the rules for recommending power boxes to adjust the recommended maintenance power boxes according to different seasons and time periods. During the application process, the operator can choose a power box with good performance recommended by the system, or he can choose it on his own.

[0058] In actual use, the operator can first submit a maintenance application to the system. In the application, the operator must select the plant, area, equipment, and fill in the fault content. Then, based on the application submitted by the operator, the approval personnel can re-approve the document in the system and approve the use of the power box; then, the system will decompose the application content.

[0059] Here, in the process of the system decomposing the application content, the system first obtains whether there is an online power box with normal self-test in the area based on the factory and regional information; then, based on the equipment information under maintenance, the maintenance records of the same equipment are counted; then, based on the phenomenon fault information, the maintenance records with the same or similar fault information are matched from the statistical maintenance records; further, the historical maintenance records are counted, and the interface and maintenance time recommended after comprehensive analysis are given, and the maintenance record information with the highest matching degree is simultaneously given for reference by relevant staff; further, the recommended information is displayed to the applicant and the safety officer, and the applicant can choose the equipment recommended by the system, or modify the information, and the safety officer will review it; finally, after the safety officer's review is passed, the equipment is remotely activated and locked, and the status of the maintenance power box is modified, where the maintenance power box status includes idle state, locked state, and in-use state.

[0060] In an optional embodiment, the system controller determines the electrical equipment that needs to be temporarily powered, including:

[0061] First, the system controller receives the use application information of the power box, wherein the use application information includes the equipment identification information of the power equipment that needs to use the power box for temporary power supply and the personnel identity information; wherein the equipment identification information can be the identification code of the power equipment and other identifications used to distinguish the power equipment, and the equipment identifications of the same model of power equipment can be the same, and the personnel identity information can be the identification number of the relevant personnel and other information that can distinguish and locate the personnel. Specifically, when the relevant personnel need to apply for the power box to temporarily power the faulty power equipment, the use application information is sent to the system controller through the computer terminal, including the equipment identification information of the power equipment that needs to be repaired and the personnel's own identity information.

[0062] Then, the device identification information and the personnel identity information are sent to a remote audit host computer; wherein the audit host computer can be a computer terminal used by relevant auditors, and the relevant auditors can review the device identification information and personnel identity information of the power equipment that needs to be temporarily powered by a power box at the audit host computer to determine whether the personnel has the authority to use the power box and repair the power equipment.

[0063] Finally, in response to the use permission information sent by the audit host computer, the power equipment that needs to be temporarily powered is determined based on the equipment identification information. Here, if the relevant auditor determines that the person has the authority to use the power box and repair the power equipment, the use permission information can be sent to the system controller. The embodiment provided by the present application can review the use application of the power box, and only after the review is passed can the subsequent power box recommendation work be carried out, thereby improving the management ability of the power box.

[0064] In an optional embodiment, each of the power supply boxes is used to output a power supply voltage of a voltage level; the usage application information also includes fault phenomenon information and regional information of the area where the power equipment is located; here, the system controller can determine the regional information of the area where the power equipment is located in the usage application information as the regional condition of the power equipment.

[0065] Furthermore, the system controller is further configured to perform the following processing:

[0066] First, the system controller receives maintenance completion information, wherein the maintenance completion information includes equipment identification information of the power equipment under maintenance, fault phenomenon information, and a power box identification of a power box that supplies power to the power equipment; here, when the relevant staff completes the maintenance of the power equipment and returns the power box, it is necessary to input the maintenance completion information into the system, which records the equipment identification information of the power equipment under maintenance for this task, fault phenomenon information, and a power box identification of a power box that supplies power to the power equipment.

[0067] Further, the device identification information, the fault phenomenon information and the power box identification are respectively determined as historical device identification information, historical fault phenomenon information and historical power box identification, and the historical device identification information, the historical fault phenomenon information and the historical power box identification are mapped and stored.

[0068] Furthermore, the system controller is further configured to perform the following processing:

[0069] First, the system controller determines the device identification information in the received use application information, and determines whether the device identification information is the same as the historical device identification information. Specifically, the device identification information can be compared with each stored historical device identification information to determine whether there is historical device identification information that is the same as the device identification information. Here, there can be multiple historical device identification information that is the same as the device identification information.

[0070] Then, when the device identification information is the same as the historical device identification information, the historical fault phenomenon information and the historical power box identification stored in the mapping with the historical device identification information are obtained, and it is determined whether the historical fault phenomenon information is the same as the fault phenomenon information in the use application information. Specifically, when the historical device identification information is the same as the device identification information, it can be determined that the power equipment corresponding to the device identification information and the power equipment corresponding to the historical device identification information belong to the same model of power equipment; further, the historical fault phenomenon information and the historical power box identification stored in the mapping with the historical device identification information can be obtained, and it is determined whether the obtained historical fault phenomenon information is the same as the fault phenomenon information in the use application information. When it is determined whether the historical fault phenomenon information is the same as the fault phenomenon information in the use application information, it can be determined whether the fault described in the historical fault phenomenon information belongs to the same type of fault as the fault described in the fault phenomenon information.

[0071] Then, when the historical fault phenomenon information is the same as the fault phenomenon information, the area corresponding to the area information in the use application information is determined, and it is determined whether the power box corresponding to the historical power box identifier is located in the area. Specifically, based on the area information, the area where the power equipment is located in the power plant area can be determined, and based on the historical power box identifier, the power box corresponding to the historical power box identifier can be determined, and it can be determined whether the power box is located in the area where the power equipment is located in the power plant area.

[0072] Here, there can be multiple historical device identification information that is identical to the device identification information, and each historical device identification information corresponds to mapped and stored historical fault phenomenon information and historical power box identification; further, if the number of historical fault phenomenon information that is identical to the fault phenomenon information in the application information among the above-mentioned multiple historical fault phenomenon information is also multiple, it can be determined whether the power box corresponding to the historical power box identification corresponding to each historical fault phenomenon information is within the area.

[0073] Finally, when the power supply box corresponding to the historical power supply box identifier is located in the area, the power supply box is determined as the recommended power supply box.

[0074] In the embodiment provided by the present application, when temporary power supply is required for power equipment in a certain area of ​​a power plant, it is possible to determine whether the fault of the power equipment currently requiring temporary power supply is the same as the fault of power equipment of the same model in the historical records based on the historical equipment identification information, historical fault phenomenon information in the maintenance completion information and the equipment identification information and fault phenomenon information in the use application information; and when the faults are the same, the power box in the historical records is directly selected as the recommended power box, thereby improving the efficiency of selecting the power box.

[0075] In an optional embodiment, the system controller determines whether the historical fault phenomenon information is the same as the fault phenomenon information in the use application information, including:

[0076] First, determine the historical fault sentence vector of the historical fault phenomenon information, and determine the fault sentence vector of the fault phenomenon information. Specifically, the text segment of the historical fault phenomenon information can be converted into the historical fault sentence vector, and the text segment of the fault phenomenon information can be converted into the fault sentence vector.

[0077] Here, a vector model can be used to convert historical fault phenomenon information and fault phenomenon information into sentence vectors. Here, the vector model can be any open source vector model, such as nomic-embed-text-v1, etc. The word segmenter in the vector model can be pre-imported with an industry-related entity vocabulary, which consists of equipment names and terms in the power system field, to improve the vector conversion capability of the vector model.

[0078] Then, the vector similarity between the historical fault statement vector and the fault statement vector is calculated, and it is determined whether the vector similarity meets a preset similarity threshold; wherein the similarity threshold is used to define whether the historical fault phenomenon information and the fault phenomenon information are semantically similar, and its value can be determined based on actual conditions.

[0079] Finally, if the vector similarity satisfies a preset similarity threshold, it is determined that the historical fault phenomenon information is the same as the fault phenomenon information in the use application information. Specifically, if the vector similarity is within the interval defined by the similarity threshold, it is determined that the historical fault phenomenon information and the use application information are semantically similar and refer to the same fault.

[0080] The embodiments provided in the present application can determine whether the historical fault phenomenon information and the fault phenomenon information specify the same type of fault based on whether the semantics of the historical fault phenomenon information and the fault phenomenon information in the usage application information are similar, thereby improving the ability to identify faults of the same type.

[0081] In an optional embodiment, if Figure 2 As shown, the power box 120 has a power box controller 121 and at least one power output unit 122, wherein each power output unit 122 is used to output power supply energy for temporary power supply, including power supply voltage and power supply current. Here, the power box controller 121 can be a computer device such as a single chip microcomputer, a digital signal processor, etc.

[0082] Specifically, the power box controller 121 is used to monitor in real time whether the voltage level of the supply voltage and the current level of the supply current output by the power output unit 122 are respectively within the normal voltage range and normal current range preset for the power output unit 122. When the voltage level of the supply voltage output by the power output unit 122 is not within the normal voltage range or the current level of the supply current output by the power output unit 122 is not within the normal current range, the power output unit 122 stops outputting power.

[0083] Here, when the power box controller 121 can output electric energy to the power output unit 122, the voltage level of the power supply voltage and the current level of the power supply current output by the power output unit 122 are collected based on the voltage sensor and the current sensor set at the power output port of the power output unit 122. And determine whether the voltage level of the power supply voltage and the current level of the power supply current output by the power output unit 122 are respectively within the normal voltage interval and the normal current interval preset for the power output unit 122, wherein the normal voltage interval and the normal current interval can be preset for each power output unit 122, and the values ​​of the normal voltage interval and the normal current interval can be determined according to actual conditions. Further, when the voltage level of the power supply voltage output by the power output unit 122 is not within the normal voltage interval or the current level of the power supply current output by the power output unit 122 is not within the normal current interval, the power box controller 121 stops the power output, and issues an alarm prompt message based on the sound and light alarm device (not shown in the figure) set on the power box 120.

[0084] Furthermore, the power box controller 121 is also used to monitor in real time whether the temperature value of the power box 120 exceeds a preset temperature threshold, and when the temperature value exceeds the preset temperature threshold, the power output unit 122 stops the power output; specifically, when the power box 120 is in working state, the power box controller 121 can collect the temperature value of the power box 120 based on the temperature sensor (not shown in the figure) set in the power box 120, and determine whether the temperature value exceeds the preset temperature threshold, wherein the temperature threshold can be determined based on the actual situation. Furthermore, when the temperature value exceeds the temperature threshold, all power output units 122 in the power box 120 stop the power output, and send out an alarm prompt message.

[0085] Furthermore, the power box controller 121 is also used to respond to a power-off instruction sent by a remote host computer (not shown in the figure) to stop all the power output units 122 of the power box 120 from outputting power. Here, the host computer can be a monitoring terminal used by a safety officer. When the safety officer finds through a camera or on-site inspection that the person using the power box 120 has made an incorrect operation or the working environment does not meet the safety standards, the monitoring terminal sends a power-off instruction to the power box controller 121 of the power box 120, so that the power box controller 121 controls all the power output units 122 of the power box 120 to stop outputting power. Here, the power box controller 121 can establish wireless communication with the host computer through a wireless communication unit (not shown in the figure) provided at the power box 120 to receive the power-off instruction.

[0086] Furthermore, an emergency stop button (not shown in the figure) is also provided at the power box 120, and the emergency stop button is connected to the power box controller 121. When the power box controller 121 recognizes that the emergency stop button is pressed, it controls all power output units of the power box to stop power output. When the operator finds that the power box is abnormal when using the power box, he can press the emergency stop button in time to stop all power output units of the power box from outputting power, thereby ensuring the safety of the use of the power box.

[0087] In the embodiment provided by the present application, the power box can use intelligent algorithms to autonomously disconnect the output power and output an alarm message when the current, voltage, temperature and other information used are higher than the preset values, thereby realizing autonomous control of the power box, and by receiving a power-off instruction to stop the power box from working, remote control is realized, thereby improving the operability of the power box. Furthermore, the system controller can set the working time of the power box, and when the use time of the power box exceeds the use time, the output power is autonomously disconnected and an alarm message is output.

[0088] In an optional embodiment, the management system of the power box also includes an audit host computer; the use permission information includes a power box use password; the power box has a human-computer interaction interface, wherein the human-computer interaction interface can be a serial port touch screen arranged on the outer surface of the power box, which is connected to the power box controller. Here, when the audit host computer determines that the relevant personnel can use the power box to temporarily power the faulty power equipment, a power box use password can be generated, and the power box use password can be sent to the terminal of the relevant staff who issued the use application information, so that the relevant staff can know the power box use password.

[0089] Furthermore, the system controller is also used to send a power box activation instruction containing a password for using the power box to the recommended power box after determining the recommended power box for temporarily powering the electrical equipment; specifically, the system controller can send the power box password in the received usage permission information to the selected recommended power box.

[0090] Furthermore, the power box controller is used to respond to the power box activation instruction to put the power box in standby state; specifically, it is recommended that the power box controller of the power box controls each power output unit in the power box and the human-computer interaction interface to adjust from the shutdown energy-saving state to the standby state after receiving the power box activation instruction, so that relevant staff can enter the password through the human-computer interaction interface.

[0091] Furthermore, when the power box is in the standby state, in response to receiving the input password through the human-computer interaction interface, it is determined whether the input password is the same as the power box usage password. If the input password is the same as the power box usage password, the power output unit is put into operation. Specifically, if the relevant staff member wishes to use a recommended power box, the password can be entered through the human-computer interaction interface of the recommended power box. If the relevant staff member obtains the power box usage password from the review host computer, the power box usage password can be entered as the input password into the human-computer interaction interface.

[0092] Furthermore, the power box controller determines whether the input password is the same as the power box user password. If the input password is the same as the power box user password, the power output unit is put into operation, so that the relevant staff can provide temporary power supply to the power equipment through the power output unit of the recommended power box. Conversely, if the input password is different from the power box user password, the power output unit is put into a locked state and cannot output electric energy.

[0093] The embodiment provided in the present application can send a newly generated power box usage password to the recommended power box. When the password entered by the relevant staff is the same as the power box usage password, it can be determined that the person has the authority to use the power box, thereby enabling the power box to be used normally. When the password entered by the relevant staff is different from the power box usage password, it can be determined that the person does not have the authority to use the power box, thereby preventing the power box from being used normally, thereby ensuring the safety of the power equipment and improving the management capabilities of the power box.

[0094] In an optional embodiment, the usage permission information includes the personal identity information; the power box has an image acquisition device, wherein the image acquisition device can be a camera for acquiring a facial image of the power box user.

[0095] Furthermore, the system controller is further configured to send a power box activation instruction to the recommended power box after determining the recommended power box for temporarily supplying power to the electrical equipment.

[0096] Furthermore, the power box controller is used to put the power box into standby state in response to the power box activation instruction. Specifically, it is recommended that the power box controller of the power box controls each power output unit and the image acquisition device in the power box to adjust from the shutdown energy-saving state to the standby state after receiving the power box activation instruction, so that the power box controller can capture facial images of relevant staff through the image acquisition device.

[0097] Furthermore, when the power box is in standby mode, the facial image of the maintenance personnel is captured by the image acquisition device and the facial image is sent to the system controller; specifically, if the relevant staff member wants to use the power box, he needs to use the image acquisition device of the power box to capture his own facial image. Here, when the system controller does not obtain the facial image captured by the power box, it will control the power box controller so that the power output unit cannot output electrical energy to ensure safety.

[0098] Furthermore, the system controller is further configured to perform the following processing:

[0099] First, the system controller responds to the facial image received from the power box controller by performing a feature comparison between the facial image and a plurality of pre-stored local facial images, and obtains identity information corresponding to the facial image based on the comparison results of the feature comparison, wherein the plurality of local facial images include facial image information of a plurality of registered persons captured at different image capture angles.

[0100] Here, the system will collect multiple facial images of each registered person in the power plant as local facial images, wherein the multiple local facial images of each registered person are mapped and stored with the identity information of the staff member. Here, the multiple local facial images of each registered person are images collected at different image collection angles, so that the system can obtain facial images of each registered person at different angles.

[0101] Specifically, the system controller will perform feature comparison between the facial image received from the power box controller and all local facial images, determine the feature similarity between the facial image and each local facial image, and when the feature similarity between the facial image and a local facial image meets a preset feature similarity threshold, the identity information stored in the mapping with the local facial image will be determined as the identity information of the facial image.

[0102] Furthermore, when the identity information is the same as the personal identity information in the use permission information, a running instruction is sent to the power box controller of the power box, so that when the power box controller receives the running instruction, the power output unit of the power box is in a running state. Conversely, when the identity information is different from the personal identity information, a locking instruction is sent to the power box controller of the power box, so that when the power box controller receives the locking instruction, the power output unit of the power box is in a locked state and cannot output electrical energy to the outside.

[0103] The embodiment provided in the present application can determine whether the person corresponding to the facial image captured by the power box has the authority to use the power box. When the person corresponding to the facial image does not have the authority to use the power box, the power box is disabled, thereby improving the management capability of the power box.

[0104] In an optional embodiment, the power box controller and the power output unit of the power box are arranged in a hard shell with a hatch. The relevant staff need to open the hatch before using the power box. Here, the hatch can be provided with a hatch lock, which is used to lock the hatch so that the relevant staff cannot use the power box. Furthermore, the power box is also provided with a positioning device.

[0105] Furthermore, the power box controller is also configured to perform the following processing:

[0106] First, when the power box is not in the standby state, if it is detected that the hatch is in the open state, an abnormal opening alarm containing the identification information of the power box is sent to the audit host computer. Here, when the power box does not receive the power box activation instruction and is not in the standby state, it can be determined that the system has no plan to use the power box. At this time, if it is found that the hatch of the power box is abnormally opened, it can be determined that someone is going to use the power box without authorization. At this time, an abnormal opening alarm containing the identification information of the power box can be sent to the audit host computer.

[0107] Furthermore, when the auditor or safety officer receives an abnormal start-up alarm through the audit host computer, the power box can be located through the identification information of the power box contained in the abnormal start-up alarm, and then the camera can be called to determine the image of the power box, or the location of the power box can be checked. Here, the audit host computer can determine the location of the power box through the positioning device of the power box, and call the camera that can capture the image of the above location to check the status of the power box, or go to the location of the power box to check the status of the power box. Furthermore, if it is found that someone is illegally using the power box, a power-off command can be sent to the power box controller corresponding to the power box through the audit host computer.

[0108] Finally, in response to the power-off command received from the audit host computer, all the power output units of the power box are unable to output electrical energy, so that the power box is in an unusable state. The embodiment provided by the present application can promptly inform the relevant staff of the abnormal situation of the power box when the power box is abnormally opened. When the relevant staff determines that the power box is illegally used, the power box can be locked through the audit host computer. Conversely, if the relevant staff finds that the power equipment is in an emergency state and an employee uses the power box without having time to carry out the normal process, the power-off command can be sent to the power box without the audit host computer, so that the power box can continue to provide temporary power supply, thereby improving the management ability of the power box.

[0109] In an optional embodiment, an energy storage device is provided in the power box, wherein the energy storage device may be an energy storage device such as a battery, and the energy storage device is used to provide working power for the power box controller and the power output unit.

[0110] Furthermore, the power box controller is also configured to perform the following processing:

[0111] First, the power box controller controls the energy storage device to supply power to the power output unit at every preset time interval, and controls the power output unit to output power multiple times at a fixed output power, wherein the output voltage of each power output is different, and the length of the preset time interval can be determined according to actual conditions. Specifically, the power box controller can control the energy storage device to provide operating power to the power output unit at every preset time interval, and at the same time, the power box controller controls the power output unit to output power multiple times at a fixed output power.

[0112] Then, based on the output power and the output voltage at each electric energy output, the output current at each electric energy output is calculated, and the arc information of the arc generated by the power output unit each time the power output unit outputs electric energy is collected. Here, the unit of the arc information can be joule. Further, if the power output unit outputs electric energy multiple times with a fixed output power, and the output voltage is different each time, the output current at each electric energy output can be calculated according to the electric power calculation formula: W (watt) = I (ampere) · V (volt). Here, the arc information generated by the power output unit each time the power output unit outputs electric energy can be collected based on the arc energy collector set in the power box.

[0113] Then, determine whether the current values ​​of all the output currents are within the preset normal current range, and whether all the arc information is within the preset normal arc range; wherein, the values ​​and measurement units of the normal current range and the normal arc range can be determined based on actual conditions.

[0114] Finally, when there are multiple power outputs, if the current value of the output current is not within the preset normal current range, or if the arc information is not within the preset normal arc range, it is determined that the power supply box is in an abnormal state, and an abnormal alarm message containing the identification information of the power supply box is sent to the system controller. Specifically, when the output current of a power output unit is not within the normal current range during a certain power output, or when the arc information of a power output unit is not within the preset normal arc range during a certain power output, it is determined that the power supply box is in an abnormal state, and an abnormal alarm message containing the identification information of the power supply box is sent to the system controller, so that the system controller will not determine the abnormal power supply box as a recommended power supply box.

[0115] Furthermore, the power box controller can also collect the temperature value of the power box when the power output unit is outputting electric energy. When the temperature value of the power box exceeds a preset upper temperature limit, it is determined that the power box is in an abnormal state, and an abnormal alarm message containing identification information of the power box is sent to the system controller, so that the system controller cannot determine the abnormal power box as a recommended power box.

[0116] Furthermore, when the power output unit is outputting electric energy, the power box controller can also collect the collected value of the output current of the power output unit when it is outputting electric energy through the current sensor, and calculate the calculated value of the output current of this electric energy output through the electric power calculation formula based on the output power and output voltage during this electric energy output; and calculate the current difference between the calculated value and the collected value. Furthermore, the current difference is compared with the preset normal difference interval to determine whether the current difference is within the normal difference interval. If the current difference is not within the normal difference interval, it is determined that the power box is in an abnormal state, and an abnormal alarm message containing the identification information of the power box is sent to the system controller, so that the system controller will not determine the abnormal power box as a recommended power box.

[0117] The embodiment provided by the present application can make the power box perform self-inspection at regular intervals. Here, the power box can use its own energy storage device to power the power supply for regular self-inspection when the power is not connected. During the self-inspection process, the energy storage device provides multiple intermittent power supply to each power output unit. The system will count the current, voltage, temperature and arc information of each power output unit, and determine whether the power box is abnormal based on the above information. After the statistics are completed, the self-inspection information is synchronously uploaded to the remote control platform. In the process of selecting the power box, the power box with normal self-inspection will be given priority in the recommendation, and the power box with abnormal self-inspection will issue an alarm and prompt according to the self-inspection results and output fault point information, thereby improving the management ability of the power box.

[0118] The present invention provides a power box management system, which can select a more suitable power box and recommend it to relevant staff based on the demand conditions of the power equipment that needs to be temporarily powered. At the same time, it can also quickly select a power box that can meet the needs through the historical use records of the power box. Furthermore, it can ensure that only personnel with permission can use the power box through passwords, face recognition, etc., and issue an alarm in time when the power box is used illegally to remind relevant staff to handle it. In addition, the power box can also perform self-inspections regularly, so that the power box with abnormal self-inspections cannot be determined as a recommended power box, thereby ensuring the effectiveness of the power box selection. Furthermore, when it is found that the power box has a circuit abnormality when in use, the power output of the power box can be cut off autonomously, thereby ensuring the safety of the use of the power box and effectively improving the management ability of the power box.

[0119] The above serial numbers of this application are only for description and do not represent the advantages and disadvantages of the implementation scenarios. The above disclosure is only a few specific implementation scenarios of this application, but this application is not limited to them, and any changes that can be thought of by technicians in this field should fall within the scope of protection of this application.
