Description

Technical Field

[0001] This application relates to the field of power systems, and in particular to a method and system for controlling IES enclosures. Background Technology

[0002] Traction systems include converters, such as those used to drive one or more traction motors or to supply power to AC and DC loads. Converters are typically housed in enclosures that are well-suited to the vehicle design and ensure efficient use of available space. In particular, in metro systems, these converter enclosures are located under the floor for easy connection to the traction motors.

[0003] There is an IES converter enclosure for use in rail vehicle traction systems. It mainly connects or disconnects the circuits between the power supply sections of the contact network through a set of disconnecting switches, thereby supplying power to the traction inverter, auxiliary inverter, and busbar, thus indirectly powering the traction system. The other set of disconnecting switches is used for grounding protection.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: when power is supplied through partial power supply disconnect switches, if the power required by the power supply object is inconsistent with the power supplied by the disconnect switch, i.e., if the disconnect switch may be malfunctioning, the relevant person in charge cannot detect it in time. Summary of the Invention

[0005] To improve the accuracy and efficiency of detecting problematic disconnect switches, this application provides an IES enclosure control method and system.

[0006] Firstly, this application provides an IES enclosure control method, which adopts the following technical solution:

[0007] An IES enclosure management method includes:

[0008] Extract the disconnect switches and their functions that supply power from the preset objects and functions of different levels of disconnect switches;

[0009] Based on the correspondence between the power supply object and the theoretical power supply demand information, the theoretical power supply demand information of the extracted target object is analyzed and determined. The theoretical power supply demand information includes the power supply voltage value and the power supply current value.

[0010] Obtain actual power supply information;

[0011] Based on the comparison between the actual power supply information and the theoretical power supply demand information, analyze whether there are any problems with the disconnecting switches;

[0012] If so, obtain the location information of the problematic disconnect switch and send the location information of the problematic disconnect switch to the terminal held by the person in charge;

[0013] If not, no notification will be given.

[0014] By adopting the above technical solution, the power supply status of disconnect switches used for power supply can be effectively monitored, and disconnect switches with problems can be identified in a timely manner. The location of the corresponding disconnect switches with problems can be promptly notified to the person in charge.

[0015] Optionally, sending the location information of the problematic disconnect switch to the terminal held by the person in charge includes:

[0016] Based on the pre-set contact information of the person in charge of managing the IES boxes for different time periods, analyze and determine the contact information of the person in charge of managing the IES boxes for the current time period;

[0017] Based on the contact information of the person in charge, the location information of the problematic disconnect switch is sent to the terminal held by the person in charge.

[0018] By adopting the above technical solution, and taking into account that the person in charge of managing the IES boxes is different at different times, the person in charge at the current time will be considered when notifying the person in charge, and the corresponding person in charge will be notified.

[0019] Optionally, it also includes a step following the transmission of the location information of the faulty disconnect switch to the terminal held by the person in charge, as follows:

[0020] Determine whether a confirmation message has been received from the terminal held by the person in charge within a preset time period;

[0021] If not, then based on the response time of the person in charge of the current period when receiving the information for the second time, the interval between the start of the next period and the current period and the response time of the person in charge of the next period when receiving the information for the first time, the person in charge with the shortest overall response time will be determined and the corresponding person in charge will be designated as the person in charge of this notification.

[0022] The location information of the problematic disconnect switch will be sent again to the terminal held by the person in charge of this notification;

[0023] If so, no further notice will be given.

[0024] By adopting the above technical solution, and further considering the situation where the person in charge does not provide timely feedback after receiving the location information, the time taken to notify the person in charge of the next time period and obtain their response versus directly notifying the person in charge of the current time period will be comprehensively considered, and the person in charge with the shortest time will be selected as the recipient of this notification.

[0025] Optionally, the analysis may identify the person in charge who has the shortest overall response time, including:

[0026] Get the interval between the start of the next time period and the current time period;

[0027] Based on the preset reaction time of the person in charge to receive information twice in different time periods, the reaction time of the person in charge to receive information twice in the current time period is analyzed and determined, and the reaction time of the person in charge to receive information twice in the current time period is taken as the overall reaction time of the person in charge in the current time period.

[0028] Based on the preset reaction time of the person in charge to receive information once in different time periods, the reaction time of the person in charge to receive information once in the next time period is analyzed and determined. The interval between the start of the next time period and the current time period and the reaction time of the person in charge to receive information once in the next time period are used as the overall reaction time of the person in charge in the next time period.

[0029] The person in charge with the shortest overall reaction time is selected as the person in charge of the shortest overall reaction time determined by the analysis.

[0030] By adopting the above technical solution, the response time of notifying the next person in charge is effectively analyzed and predicted. The overall time of the analysis and prediction is effectively compared with the overall time of the original plan to notify the person in charge at the current time, so as to conveniently and effectively determine the person in charge with the shortest overall time.

[0031] Optionally, obtaining the location information of the problematic disconnector switch includes:

[0032] Obtain the location information of the IES enclosure where the problematic disconnect switch is located, and specific photographic information of the problematic disconnect switch inside the IES enclosure;

[0033] Based on the specific photographic information of the problematic disconnector switch inside the enclosure, the specific location information of the problematic disconnector switch inside the IES enclosure is determined.

[0034] The specific location information of the problematic disconnect switch within the IES enclosure, and the location information of the IES enclosure containing the problematic disconnect switch, are combined to form the specific location information of the problematic disconnect switch within the IES enclosure.

[0035] By adopting the above technical solution, it is further considered that when notifying the person in charge, only the location of the disconnect switch with the problem is notified. After the person in charge arrives at the relevant nearby location, due to the large number of disconnect switches distributed, the person in charge still needs to conduct further analysis and judgment on the specific disconnect switch with the problem on site.

[0036] Optional, specific photographic information of the problematic disconnector within the IES enclosure includes:

[0037] Based on the correspondence between the person in charge being notified and their preferred observation perspective, analyze and determine the preferred observation perspective of the person in charge being notified.

[0038] Based on the perspective of the person in charge identified through analysis, adjust the specific photographic information of the problematic disconnect switch inside the IES enclosure.

[0039] By adopting the above technical solution, and taking into account the viewing habits of the notified person in charge, the original photos will be adjusted so that the person in charge can more effectively identify the problematic disconnect switches when observing them.

[0040] Optionally, it also includes a step that runs parallel to sending the location information of the faulty disconnect switch to the terminal held by the person in charge, as follows:

[0041] Based on the pre-defined correspondence between fault photos of disconnecting switches and fault probability distribution information, and the specific photo information of the faulty disconnecting switches inside the IES enclosure, a preliminary analysis was conducted to determine the probability distribution information of faults occurring in the disconnecting switches.

[0042] Based on the preliminary determination of the probability distribution of faults in disconnecting switches and the corresponding historical fault information of disconnecting switches, the fault information of the corresponding disconnecting switches in this instance is predicted and analyzed.

[0043] By adopting the above technical solution, combined with photographic information and historical fault information of disconnecting switches, the fault information of the corresponding disconnecting switch can be effectively analyzed and predicted.

[0044] Optionally, the predictive analysis of the corresponding disconnector switch's fault information includes:

[0045] Based on the preliminary probability distribution information of the disconnecting switch failures, analyze and determine whether the current disconnecting switch is faulty;

[0046] If so, the probability distribution information of the faults of the disconnecting switches that were initially determined will be used as the fault information of the corresponding disconnecting switches in the current analysis.

[0047] If not, then based on the historical fault information of the corresponding disconnector switch, analyze and determine the overall distribution probability of the fault, and use the overall distribution probability of the fault as the current fault information of the corresponding disconnector switch to be predicted and analyzed.

[0048] By adopting the above technical solution, the problem of how to accurately predict disconnect switches is specifically disclosed.

[0049] Secondly, this application provides an IES enclosure control system, which adopts the following technical solution:

[0050] An IES enclosure control system includes:

[0051] The extraction module is used to: extract the disconnect switches and their objects that supply power from the preset objects and functions of disconnect switches of different levels;

[0052] The analysis and determination module is used to: analyze and determine the theoretical power supply demand information of the extracted target object based on the correspondence between the power supply object and the theoretical power supply demand information, wherein the theoretical power supply demand information includes the power supply voltage value and the power supply current value;

[0053] The acquisition module is used to: acquire actual power supply information;

[0054] The problem analysis module is used to analyze whether there are any problems with the isolating switches based on the comparison results between the actual power supply information and the theoretical power supply demand information.

[0055] The notification module is used to: obtain the location information of the disconnecting switch when there is a problem, and send the location information of the disconnecting switch to the terminal held by the person in charge.

[0056] By adopting the above technical solution, the extraction module and the analysis and determination module can effectively analyze and determine the theoretical power supply demand information. The acquisition module and the problem analysis module can effectively determine whether there is a problem with the power supply of the disconnecting switch, and if there is indeed a problem, the person in charge can be notified in a timely manner.

[0057] In summary, the beneficial technical effects of this application are as follows:

[0058] 1. Improved the accuracy and efficiency of detecting disconnect switches with power supply problems, and will notify relevant personnel in advance.

[0059] 2. When notifying the person in charge, the issue with the isolating switch will also be communicated to the relevant person in charge. Attached Figure Description

[0069] The present application will be further described in detail below with reference to the accompanying drawings.

[0070] Reference Figure 1 This application discloses an IES enclosure control method, comprising:

[0071] Step S100: Extract the disconnecting switch and its target for power supply from the preset targets and functions of different levels of disconnecting switches.

[0072] The target objects and functions of the preset disconnect switches of different levels can be obtained by querying a preset database that stores the target objects and functions of disconnect switches of different levels. Specifically, there are at least three different levels of disconnect switches in this application. The disconnect switches mentioned are described below.

[0073] The first type of disconnecting switch mainly supplies power to the traction system; its function is to supply power to the traction system. The second type of disconnecting switch provides power to the auxiliary inverter and auxiliary bus; its function is to supply power to the inverter and bus. The third type of disconnecting switch provides grounding protection. When the disconnecting switch is switched to the grounded position, it can ground the traction system and the auxiliary inverter system to ensure the safe conduct of train maintenance; its function is to ground the traction system and the auxiliary inverter system.

[0074] Extract the disconnect switches that provide power and their corresponding objects. That is, use the disconnect switches that provide power and their corresponding objects as the query objects, and retrieve them from a pre-set database that stores the objects and functions of disconnect switches at different levels.

[0075] Step S200: Based on the correspondence between the power supply object and the theoretical power supply demand information, analyze and determine the theoretical power supply demand information of the extracted object, wherein the theoretical power supply demand information includes the power supply voltage value and the power supply current value.

[0076] The correspondence between power supply objects and theoretical power supply demand information can be obtained from a pre-set database that stores the correspondence between power supply objects and theoretical power supply demand information. As for the analysis and determination of the theoretical power supply demand information of the extracted objects, the extracted objects are used as the query objects and the information is obtained from a pre-set database that stores the correspondence between power supply objects and theoretical power supply demand information.

[0077] Step S300: Obtain actual power supply information.

[0078] The actual power supply information mentioned in step S300 includes voltage and current. Voltage can be detected and obtained by a voltage sensor, and current can be detected and obtained by a current sensor.

[0079] Step S400: Based on the comparison between the actual power supply information and the theoretical power supply demand information, analyze whether there is a problem with the isolating switch. If yes, proceed to step SA00; if no, proceed to step SB00.

[0080] Step SA00: Obtain the location information of the problematic disconnect switch and send the location information of the problematic disconnect switch to the terminal held by the person in charge.

[0081] The location information of the problematic disconnector can be obtained by querying a pre-set database containing the location information of disconnectors, using the problematic disconnector as the query object.

[0082] Step SB00, no notification.

[0083] The implementation principle of this embodiment is as follows:

[0084] Based on the actual power supply of the disconnecting switch, we analyze and determine whether the power supply of the disconnecting switch meets expectations. If the actual power supply of the disconnecting switch does not meet expectations, we will promptly notify the person in charge.

[0085] exist Figure 1 In step SA00, since the person in charge of managing the IES box may not be the same person at different times, to further ensure that the notified person in charge is indeed the person in charge of managing the IES box for the corresponding time period, it is necessary to send the location information of the problematic disconnect switch to the terminal held by the person in charge for further analysis and judgment. Specifically, this is done through... Figure 2The illustrated embodiments will be described in detail.

[0086] Reference Figure 2 Sending the location information of the problematic disconnect switch to the terminal held by the person in charge includes:

[0087] Step SA10: Based on the preset contact information of the person in charge of managing the IES boxes for different time periods, analyze and determine the contact information of the person in charge of managing the IES boxes for the current time period.

[0088] The contact information of the person in charge of managing the IES box in different time periods can be obtained by querying a database that stores the contact information of the person in charge of managing the IES box in different time periods. The analysis and determination of the contact information of the person in charge of managing the IES box in the current time period can be obtained by querying the database that stores the contact information of the person in charge of managing the IES box in different time periods, with the current time period as the object.

[0089] Step SA20: Based on the contact information of the person in charge, send the location information of the disconnect switch with the problem to the terminal held by the person in charge.

[0090] The terminal held by the person in charge can be a mobile phone, a laptop, or other communicable devices. The location information of the problematic disconnect switch can be sent to the terminal held by the person in charge via SMS, WeChat, or other communication methods.

[0091] The implementation principle of this embodiment is as follows:

[0092] Based on the person in charge of managing the IES enclosure at different times, the person in charge of the current IES enclosure is determined, thereby effectively ensuring that the appropriate person can be notified in a timely manner when there is a power supply problem to the isolating switch of the IES enclosure.

[0093] exist Figure 1 In step SA00, considering the response of the notified person in charge to the received disconnector location information, and to further ensure that the notified person in charge is capable of responding promptly and providing feedback, it is necessary to add an analysis and judgment of the person in charge's response after sending the location information of the problematic disconnector to the terminal held by the person in charge. Specifically, this is done through... Figure 3 The illustrated embodiments will be described in detail.

[0094] Reference Figure 3 An IES enclosure control method also includes a step following the transmission of the location information of the faulty disconnect switch to the terminal held by the person in charge, as follows:

[0095] Step SC00: Determine whether a confirmation message has been received from the terminal held by the person in charge within a preset time period. If not, proceed to step SD00; if yes, proceed to step SF00.

[0096] The preset time period mentioned in step SC00 can be 1 minute or 2 minutes, or it can be set based on user needs.

[0097] Step SD00: Based on the response time of the person in charge of the current time period when receiving information for the second time, the interval between the start of the next time period and the current time period and the response time of the person in charge of the next time period when receiving information for the first time, analyze and determine the person in charge with the shortest overall response time, and designate the corresponding person in charge as the person in charge of this notification.

[0098] The reaction time for the person in charge of the current time period to receive information for the second time can be obtained by querying a preset database that stores the information received by the person in charge of the current time period for the second time. In addition, the interval between the start of the next time period and the current time period is the time difference between the start time of the next time period and the current time period. The reaction time for the person in charge of the next time period to receive information for the first time can be obtained by querying a preset database that stores the reaction time for the person in charge to receive information for the first time.

[0099] The analysis and determination of the person in charge with the shortest overall response time was based on the overall response time of different persons in charge, and the person in charge with the shortest overall response time was selected as the person in charge of this notification.

[0100] Step SE00: Send the location information of the problematic disconnect switch to the terminal held by the person in charge of this notification again.

[0101] Step SF00, no further notification will be given.

[0102] The implementation principle of this embodiment is as follows:

[0103] By comprehensively considering the overall response time of notifying the next responsible person and the response time of the current responsible person to the second information reception, we can compare and analyze to determine the most suitable responsible person to be notified, and then notify the corresponding responsible person as the notification recipient.

[0104] exist Figure 3 In step SD00, considering that the reaction time of each person receiving information for the first and second time differs during the process of determining the person in charge with the shortest overall response time, which may affect the effective selection of the person in charge, further analysis and determination of the person in charge with the shortest overall response time are required. See [link / reference] for details. Figure 4 The illustrated embodiment.

[0105] Reference Figure 4The analysis identified the individuals responsible for the shortest overall response time, including:

[0106] Step SD10: Obtain the interval between the start of the next time period and the current time period.

[0107] The interval between the start of the next time period and the current time period is the time interval between the start of the next time period and the current time period.

[0108] For example, assuming the current time period is 9:50 and the next time period starts at 9:52, we can determine that the interval between the start of the next time period and the current time period is 2 minutes.

[0109] Step SD20: Based on the preset reaction time of the person in charge receiving information for the second time in different time periods, analyze and determine the reaction time of the person in charge receiving information for the second time in the current time period, and take the reaction time of the person in charge receiving information for the second time in the current time period as the overall reaction time of the person in charge in the current time period.

[0110] The preset response time of the person in charge to receive information twice at different time periods can be obtained by querying a database that stores the response time of the person in charge to receive information twice at different time periods. The response time of the person in charge to receive information twice at different time periods can be obtained by querying the database that stores the response time of the person in charge to receive information twice at different time periods, with the person in charge and the time period as the common query objects.

[0111] Step SD30: Based on the preset reaction time of the person in charge receiving information once in different time periods, analyze and determine the reaction time of the person in charge receiving information once in the next time period, and take the interval between the start of the next time period and the current time period and the reaction time of the person in charge receiving information once in the next time period as the overall reaction time of the person in charge in the next time period.

[0112] The preset response time of the person in charge to receive information at different time periods can be obtained by querying the database containing the preset response time of the person in charge to receive information at different time periods; the response time of the person in charge to receive information at the next time period can be obtained by querying the database containing the preset response time of the person in charge to receive information at different time periods, using the person in charge and the time period as the query objects.

[0113] Step SD40: Select the person in charge with the shortest overall reaction time as the person in charge of the shortest overall reaction time determined by the analysis.

[0114] The implementation principle of this embodiment is as follows:

[0115] By further considering the reaction time of the person in charge in the current period and the person in charge in the next period when receiving information for the first and second time, we can better analyze the overall time spent by each person in charge, and thus more accurately identify the appropriate person in charge.

[0116] exist Figure 1 In step SA00, further consideration is given to the notified person in charge. Since there are many disconnectors in the IES, the person in charge will need to spend considerable time locating the problematic disconnector. Therefore, further analysis is conducted on obtaining the location information of the problematic disconnector. See details below. Figure 5 , .

[0117] Reference Figure 5 The acquisition of location information for the problematic disconnector includes:

[0118] Step SAa0: Obtain the location information of the IES box containing the problematic disconnect switch and the specific photo information of the problematic disconnect switch inside the IES box.

[0119] The location information of the IES enclosure containing the problematic disconnect switch can be obtained from a pre-set database that stores the location information of the IES enclosure containing the problematic disconnect switch. The specific photographic information of the problematic disconnect switch inside the IES enclosure can be obtained by taking a photographic image of the problematic disconnect switch inside the IES enclosure using a camera device installed inside the IES enclosure.

[0120] Step SAb0: Based on the specific photographic information of the problematic disconnector switch inside the enclosure, determine the specific location of the problematic disconnector switch inside the IES enclosure.

[0121] The specific location of the problematic disconnector within the IES enclosure can be determined by marking the problematic disconnector using software.

[0122] Step SAc0: Combine the specific location information of the problematic disconnector within the IES enclosure and the location information of the IES enclosure containing the problematic disconnector into the specific location information of the problematic disconnector within the IES enclosure.

[0123] The implementation principle of this embodiment is as follows:

[0124] Once the problematic disconnect switch is identified, its location can be promptly photographed and the problematic disconnect switch can be delineated, thereby improving the efficiency of finding the problematic disconnect switch when the person in charge arrives at the site.

[0125] exist Figure 5In step SAa0, further consideration is given to the fact that after the person in charge arrives at the corresponding position, since the initial photo is taken from a positive angle, and each person in charge has their own specific observation perspective, they can locate the problematic disconnect switch more quickly from this perspective. Therefore, further analysis is needed to obtain specific photo information of the problematic disconnect switch within the IES enclosure. See [link to relevant documentation] for details. Figure 6 The illustrated embodiment.

[0126] Reference Figure 6 The acquisition of specific photographic information about the problematic disconnect switch inside the IES enclosure includes:

[0127] Step SAa1: Based on the correspondence between the person in charge being notified and their preferred observation perspective, analyze and determine the preferred observation perspective of the person in charge being notified.

[0128] The correspondence between the notified person in charge and their preferred observation perspective can be obtained by querying a pre-set database that stores the correspondence between the person in charge and their preferred observation perspective. The analysis to determine the preferred observation perspective of the notified person in charge can be performed by querying the person in charge as the query object from the pre-set database that stores the correspondence between the person in charge and their preferred observation perspective.

[0129] Step SAa2: Based on the perspective of the notified person in charge as determined by the analysis, adjust the specific photographic information of the problematic disconnect switch inside the IES enclosure.

[0130] The method for adjusting the specific photographic information of the problematic disconnector switch inside the IES enclosure is as follows: Obtain a panoramic photograph of the problematic disconnector switch inside the IES enclosure, and then adjust the corresponding photograph from the panoramic photograph at the angle preferred by the person in charge so that the photograph matches the person in charge's observation perspective.

[0131] The implementation principle of this embodiment is as follows:

[0132] After identifying the problematic disconnect switch, the viewing angle of the relevant disconnect switch will be adjusted to meet the requirements of the notified person in charge.

[0133] exist Figure 1 In step SA00, it is also considered that when notifying the person in charge, they should be given some hints about the problems with the disconnecting switch, and the problems with the disconnecting switch should also be analyzed. See details below. Figure 7 The illustrated embodiment.

[0134] Reference Figure 7 An IES enclosure control method also includes a step that runs parallel to sending the location information of the faulty disconnect switch to the terminal held by the person in charge, as follows:

[0135] Step Sa00: Based on the pre-defined correspondence between fault photos of disconnecting switches and fault probability distribution information, and the specific photo information of the faulty disconnecting switch inside the IES box, a preliminary analysis is conducted to determine the probability distribution information of the faults of the disconnecting switches.

[0136] The pre-defined correspondence between fault photos of disconnecting switches and fault probability distribution information can be obtained from a pre-defined database that stores the correspondence between fault photos of disconnecting switches and fault probability distribution information. Preliminary analysis determines that the probability distribution information of faults of disconnecting switches can be obtained by querying the specific photos of the faulty disconnecting switches inside the IES enclosure, using the photos as the query object.

[0137] In addition, the following are some of the faults of disconnecting switches: 1. During operation, there may be an electric arc, which may burn the contact surfaces of the moving and stationary contacts. Various moving parts may wear or deform, affecting the contact of the contact surfaces; 2. During operation, the contact tightening parts of the disconnecting switch may become loose, resulting in poor contact. As a result, the spring plates of the blades or blade tips may rust or overheat, which will reduce the spring pressure. After the disconnecting switch is opened, the contacts are exposed to the air, which is prone to oxidation and dirt.

[0138] Step Sb00: Based on the initially determined probability distribution information of the faults of the disconnecting switches and the historical fault information of the corresponding disconnecting switches, predict and analyze the current fault information of the corresponding disconnecting switches.

[0139] Specifically, firstly, based on the initially determined probability distribution information of faults occurring in disconnecting switches, it is analyzed to determine whether a fault exists in the current disconnecting switch; if yes, the initially determined probability distribution information of faults occurring in disconnecting switches is used as the fault information of the corresponding disconnecting switch in the current analysis; if no, based on the historical fault information of the corresponding disconnecting switch, the overall distribution probability of the fault is analyzed and determined, and the overall distribution probability of the fault is used as the fault information of the corresponding disconnecting switch in the current analysis.

[0140] The implementation principle of this embodiment is as follows:

[0141] When photographing a faulty disconnect switch, a preliminary judgment can be made based on the photo, which facilitates the initial determination of the possible faults of the disconnect switch. If the photo cannot be used to determine the fault, the fault information of the disconnect switch in this case will be determined based on the historical fault information of the disconnect switch.

[0142] Reference Figure 8 Based on the same inventive concept, this application also discloses an IES enclosure control system, specifically including the following:

[0143] Extraction module 1 is used to: extract the disconnect switches and their functions that provide power supply from the preset objects and functions of disconnect switches of different levels;

[0145] Module 3 is used to: acquire actual power supply information;

[0146] Problem Analysis Module 4 is used to: analyze whether there are any problems with the isolating switches based on the comparison results between the actual power supply information and the theoretical power supply demand information.

[0148] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
