[0002] Usually, when workers are working underground, they need to carry positioning cards. The positioning cards carried by the workers and the positioning substations deployed underground can obtain the real-time location of the workers, which plays a key role in protecting the lives of the workers. However, during the long-term operation of the mine, due to the complex working environment in the mine, such as the high temperature and high humidity environment, and the presence of harmful dust such as coal dust in the air, it is easy to cause the positioning substation or positioning card to malfunction. Based on this, it is necessary to regularly analyze and maintain the operating status of the positioning substation and positioning card.

[0003] At present, the methods for analyzing and maintaining positioning substations include: real-time positioning and monitoring of positioning substations, manual regular inspections of each positioning substation, and setting positioning substations to report status data at a certain frequency. Real-time positioning and monitoring of positioning substations will lead to excessive consumption of material and human resources; manual regular inspections of each positioning substation are periodic and cannot achieve real-time operating status monitoring and maintenance of the positioning substation; ideally, each positioning substation will report status data at a certain frequency, but there is a phenomenon that the status data reported by the positioning substation is normal and the positioning substation is also in an abnormal state. The above-mentioned methods for analyzing and maintaining positioning substations may result in failure to detect faults in the positioning substation, which may lead to the inability to arrange maintenance in a timely manner, the loss of underground personnel trajectories, and the inability of underground personnel to make emergency calls for help when they are in danger.

The technical solution can be applied to determine whether a positioning substation in a mine or a positioning device worn by a user working in a mine is faulty.

[0038] Embodiment 1

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] Figure 1 It is a flow chart of a fault determination method for mine equipment provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to situations where a positioning substation and / or a positioning card is faulty. The method can be executed by a fault determination device for mine equipment. The device can be implemented in the form of software and / or hardware. The hardware can be an electronic device such as a server. The electronic device can execute the fault determination method for mine equipment provided by the present technical solution.

[0041] like Figure 1 As shown, the method includes:

[0042] S110. Acquire positioning card trajectory data collected by at least one positioning substation within a target time range, wherein the positioning card trajectory data is data collected when a positioning device worn by a user working underground in a mine communicates with the positioning substation, and the positioning card trajectory data also includes installation location data of the positioning substation.

[0043] Among them, the positioning substation is a key device in the underground coal mine worker positioning system, responsible for data collection and upload. The positioning substation communicates with the positioning card through a wireless connection, collects the location information of the underground workers, obtains the real-time location of the underground workers, and uploads this information to the data processing center, so as to not only realize the real-time monitoring and dispatch of the underground workers, but also provide real-time personnel location information in case of emergency, and carry out timely emergency disposal and rescue, which plays a key role in protecting the life safety of mine workers.

[0044] The underground positioning substation of coal mines generally has strong compatibility and can support a variety of positioning cards to facilitate system maintenance and upgrades. The coverage diameter of the positioning substation can reach 2,000 meters. The transmission method of the positioning substation can be transmitted using Ethernet and serial vehicle bus standards, ensuring the stability and efficiency of data transmission. Because the positioning substation is set up underground in the coal mine, it has an explosion-proof design to improve safety. When the positioning substation displays data, the graphical and tabular data display method based on the browser makes the information display more intuitive.

[0045] Positioning substations are divided into precise positioning stations and regional positioning stations. The main difference between precise positioning stations and regional positioning stations lies in positioning accuracy and application scenarios. Precise positioning stations provide high-precision location information, usually at the centimeter level or even higher, while regional positioning stations provide location information over a larger range with lower accuracy. Precise positioning stations usually use high-precision positioning technologies, such as ultra-wideband technology, which can achieve a positioning accuracy of 30 cm or even higher. This technology uses ultra-wideband signals and multiple anchor points, is suitable for scenarios that require high-precision location information, can respond quickly to various emergencies, and exhibits good anti-interference capabilities in complex environments. Regional positioning stations are a more basic positioning system that can only determine the approximate location of a person. This system is suitable for scenarios where it is necessary to locate and track people within the entire area without the need to record specific location coordinates. The equipment and deployment of the regional positioning system are relatively simple, and it is easy to use and maintain.

[0046] Among them, the positioning devices worn by users working underground in mines refer to the devices that are matched with signal receiving devices such as positioning substations, which are used to track and monitor the specific location of miners in underground mines. Positioning devices are usually worn by users working underground in mines to ensure their safety and provide rapid rescue response in emergency situations.

[0047] Among them, the positioning card is a type of positioning device worn by users working underground in mines. The positioning card can communicate with the positioning substation through wireless connection.

[0048] The target time range refers to the time period during which the positioning substation collects the positioning card trajectory data. For example, the staff will obtain the positioning card trajectory data collected by the positioning substation within 24 hours of the previous day in the early morning of the next day.

[0049] The positioning card trajectory data refers to all data information collected by the positioning substation during the movement of one or more moving positioning cards within the target time range, including the location of the sampling point, the sampling time, etc.

[0050] The installation location data refers to the installation location of the target positioning substation in the mine. For example, a target positioning substation is installed at a location 500 meters below the A tunnel in the mine.

[0051] On the basis of the above-mentioned technical solutions, before obtaining the positioning card trajectory data collected by at least one positioning substation within the target time range, it is also necessary to first determine the positioning card trajectory data determination model. In this embodiment, the positioning card trajectory data determination model can be determined by: according to a preset collection frequency, the positioning substation collects the positioning data of at least one positioning card within the scope, wherein the positioning data is used to characterize the working position of the working user, and the scope is the network coverage of the positioning substation; and the positioning data is used as the positioning card trajectory data.

[0052] The preset collection frequency means that the positioning substation will collect the location data of all positioning cards within its range at a certain frequency. For example, a positioning substation will collect the location data of all positioning cards within its range every 2 seconds.

[0053] The scope refers to the network coverage of the positioning substation, that is, the positioning substation can only collect the trajectory data of the positioning card within the network coverage. For example, the network coverage of a positioning substation can reach a diameter of 1,000 meters.

[0054] Among them, the positioning data refers to the real-time working position of the working user carrying the positioning card in the mine. For example, if a working user is working at 10 meters in Lane A, then 10 meters in Lane A is the positioning data of the working user, and the positioning data is used as the trajectory data of the positioning card.

[0055] Specifically, the data collected by at least one positioning substation within the target time range at a preset collection frequency when communicating with the positioning card within the scope is obtained. These data are positioning data representing the working position of the working user. At the same time, the installation location data of the positioning substation is also obtained, and these data are used as the trajectory data of the positioning card. And the network coverage range of each positioning substation is the scope of the positioning substation.

[0056] For example, in the early morning of the same day, the staff obtains the operating position data of 10 positioning cards collected every 2 seconds by 20 positioning substations with a coverage range of 1000 meters in diameter within 24 hours of the previous day. Among them, the installation position data of the 20 positioning substations are obtained. The 10 positioning cards are the positioning cards carried by the 10 staff members working in the mine within 24 hours of the previous day. The collected operating position data is the positioning data, which is also used as the trajectory data of the 10 positioning cards.

[0057] S120 , preprocessing the positioning card trajectory data according to the early warning positioning substations received within the target time range and the data constraint conditions to obtain trajectory data to be applied.

[0058] Among them, the early warning positioning substation refers to the positioning substation that has been determined to be abnormal through manual inspection or the abnormal positioning substation automatically reported by the system. The positioning card track data in the above abnormal positioning substation needs to be eliminated.

[0059] The data constraint condition refers to excluding the positioning card trajectory data collected by the preset positioning substation.

[0060] Among them, the preprocessing of the positioning card trajectory data refers to the elimination of the positioning card trajectory data of the positioning substations determined to be abnormal by manual inspection, the positioning card trajectory data of the abnormal positioning substations automatically reported by the system, the positioning card trajectory data of the positioning substations not located underground, and the positioning card trajectory data of the positioning substations of the regional positioning stations.

[0061] The pre-processed positioning card trajectory data is referred to as the trajectory data to be applied. The trajectory data to be applied is the data after the positioning card trajectory data is cleaned and eliminated.

[0062] Specifically, the trajectory data of the positioning card received within the target time range, the trajectory data of the positioning card collected by the positioning substation with manual inspection anomalies, the trajectory data collected by the positioning substation with automatic abnormality reported by the system, the trajectory data of the positioning card collected by the positioning substation not located in the mine, and the trajectory data collected by the regional positioning station are all eliminated. The trajectory data after being eliminated and pre-processed is the trajectory data to be applied.

[0063] S130. Determine a target faulty device according to the trajectory data to be applied and at least one pre-set warning constraint condition; wherein the target faulty device includes a positioning substation with a fault and / or a positioning device worn by an operating user.

[0064] Among them, the equipment that meets at least one warning constraint condition is defined as the target faulty equipment, and the target faulty equipment includes the positioning substation with fault and / or the positioning equipment worn by the operating user.

[0065] Optionally, at least one early warning constraint condition includes: a first constraint condition, a second constraint condition, a third constraint condition and a fourth constraint condition: the first constraint condition is: the time difference between the last moment of the positioning card trajectory data collected by the positioning substation and the current moment is greater than a preset time difference threshold; the second constraint condition is: the positioning distance range of at least one user corresponding to the positioning card trajectory data collected by the positioning substation is less than a preset distance threshold; the third constraint condition is: for at least one positioning card, at least one positioning substation has not collected the positioning trajectory data of the positioning card within a preset time length; the fourth constraint condition is: for at least one positioning card, the number of data collected by the positioning card within the preset time length is less than a preset number threshold.

[0066] Specifically, Figure 2 As shown, the first constraint condition refers to: the positioning substation has not read the positioning card trajectory data for a long time, which exceeds the threshold. According to the installation location of the positioning substation, set the "abnormal duration of positioning substation card reading" of each positioning substation, such as restricting the area and restricting the entry and exit of personnel. The threshold can be set according to the on-site operation situation, for example, the threshold is set to 24 hours. Among them, the "abnormal duration of positioning substation card reading" threshold of the positioning substation can be set uniformly by all positioning substations, or it can be set individually. Then calculate the trajectory data of the previous day at regular intervals every day, and count the last card reading time of the positioning substation. If the time difference between the current system time and the last card reading is greater than the threshold, it is defined as an abnormality. One piece of data for each positioning substation: the specific output information is as follows: positioning substation number, positioning substation installation location, last card reading time, abnormal start time, and abnormal duration. Among them, the duration of abnormality = last card reading time - abnormal start time.

[0067] Exemplarily, for the target positioning substation, the "abnormal duration of positioning substation card reading" is 30 minutes. If the current time is 8:30 on February 15, and the last card reading time of the target positioning substation is 7:30 on February 15, then the time difference between the last moment of the target positioning card trajectory data collected and the current moment is 60 minutes, which is greater than the "abnormal duration of positioning substation card reading" of 30 minutes. If the time difference between the last moment of the positioning card trajectory data collected by the target positioning substation and the current moment is greater than the preset time difference threshold, then this positioning substation is defined as abnormal. Specifically output the positioning substation number, positioning substation installation location, last card reading time, abnormal start time, abnormal duration and other information.

[0068] Specifically, for the positioning card trajectory data collected by the target positioning substation, the precise number of trajectories of each positioning card in the mine passing through each target positioning substation is counted, and one piece of data is obtained for each positioning card. The specific output information is as follows: card number, name, department, the first trajectory position of the positioning card reported by the positioning substation, the time when the positioning substation reports the first trajectory of the positioning card, the last trajectory position of the positioning card reported by the positioning substation, the time when the positioning substation reports the last trajectory of the positioning card, the positioning substation installation position, the positioning substation number, and the total number of trajectories passing through the positioning substation, wherein each positioning substation calculates the total number, the straight-line distance difference between the first trajectory position and the last trajectory position, that is, the difference between the two meters. According to the installation position data in the "positioning substation installation position" in the system, and the left and right effective identification distance of the positioning substation, the signal coverage range of the positioning substation is obtained. For example, if the positioning substation is installed at 500 meters in Lane A and the effective identification distance is 500 meters to the left and right, the signal coverage range of the positioning substation is 0-1000 meters in Lane A. Set a threshold, which is generally set to 80%, and the threshold will decrease as the number of years the positioning substation is in operation increases. Divide the distance difference between the first and last track positions obtained by the signal coverage range, and calculate the average value of all people who have passed through this positioning base station. If the average value is less than the threshold, it is judged as a suspected signal range coverage anomaly.

[0069] For example, the threshold is set to 80%. If the target positioning substation is installed at 500 meters in Lane A, the effective identification distance is 500 meters to the left and right, and the signal coverage range of the positioning substation is 0-1000 meters in Lane A. If only one positioning card passes through this positioning substation within the target time range, and the calculated distance difference between the first track position and the last track position of the positioning card is 700 meters, then the positioning distance range is less than the threshold, and it is judged as a suspected signal range coverage abnormality.

[0070] Specifically, a threshold is set. Based on the set threshold, the trajectory data of the positioning card of the previous day is calculated regularly every day, and the positioning trajectory interruption distance and time of each positioning card are counted. One piece of data for each positioning card. The specific output information is as follows: card number, name, department, start time of trajectory interruption, end time of trajectory interruption, start position of trajectory interruption, and end position of trajectory interruption. The calculated positioning card data are all suspected abnormal data. Combined with the "underground blind area map", it is judged whether there should be trajectory reports in this area. If there should be trajectory reports, it is judged as suspected signal coverage abnormality.

[0071] The underground blind area map refers to the schematic diagram of the area that cannot be covered by communication due to various reasons in coal mines or other underground mining environments. These areas are usually caused by blasting, inappropriate direct wiring, etc., making it difficult to achieve comprehensive monitoring and management.

[0072] For example, the threshold value N = 180 seconds, and the cards whose underground trajectory interruption time on the 22nd exceeded 180 seconds are listed. The listed data is as follows: Card 1001, Zhang San, Unit 1, 2023-09-22, 10:01:00, 2023-09-22, 10:21:00, Lane A 100 meters, Lane A 200 meters. Combined with the underground blind area map, it is judged that there should be trajectory reports in this area, and it is judged as a suspected signal coverage anomaly.

[0073] Specifically, set a threshold, calculate the trajectory data of the previous day at a fixed time every day, and count the number of trajectories within N hours after each card enters the well that is less than the threshold. Each positioning card has one piece of data. The specific output information is as follows: card number, name, department, time of entering the well, and number of trajectories within N hours.

[0074] For example, after a person enters the well, 2S reports a trajectory, and the number of trajectories within one hour is 1800. For example, if the threshold is set to 90%, card 1001, the number of trajectories within one hour after entering the well is 1500, 1500 / 1800=83%, which is less than the set threshold of 90%. At this time, the positioning card is determined to be suspected of card reading abnormality.

[0075] Optionally, the target faulty device is determined based on the trajectory data to be applied and at least one pre-set early warning constraint, including: if the trajectory data to be applied satisfies the first constraint or the second constraint in at least one early warning constraint, the target faulty device is determined to be a positioning substation fault and the substation data of the faulty positioning substation is output; if the trajectory data to be applied satisfies the third constraint or the fourth constraint in at least one early warning constraint, the target faulty device is determined to be a positioning card fault and the positioning card data of the faulty positioning card is output.

[0076] Specifically, if the trajectory data satisfies the first constraint condition or the second constraint condition, the target faulty device is determined to be a positioning substation fault and the substation data of the faulty positioning substation is output; if the trajectory data satisfies the third constraint condition or the fourth constraint condition, the target faulty device is determined to be a positioning card fault and the positioning card data of the faulty positioning card is output.

[0077] The technical solution of the disclosed embodiment is to obtain the positioning card trajectory data collected by at least one positioning substation within the target time range, wherein the positioning card trajectory data is based on the data collected when the positioning device worn by the user working in the mine communicates with the positioning substation, and the positioning card trajectory data also includes the installation position data of the positioning substation, and then, according to the early warning positioning substation and data constraints received within the target time range, the positioning card trajectory data is pre-processed to obtain the trajectory data to be applied, and finally, according to the trajectory data to be applied and at least one pre-set early warning constraint, the target faulty device is determined, wherein the target faulty device includes the positioning substation with a fault and / or the positioning device worn by the working user. According to the trajectory data and early warning constraints, the operating status of the positioning substation and the positioning card is monitored and warned in a timely manner, the faulty positioning substation and positioning card are determined and repaired, and the safety of the operating personnel is improved.

[0078] Embodiment 2

[0079] Figure 3 The present invention provides a flowchart of a method for determining a fault of a mine equipment. Based on the above embodiment, the step S120 is described in detail. The specific implementation method can refer to the technical solution of this embodiment. The technical terms that are the same or corresponding to the above embodiment are not repeated here.

[0080] like Figure 3 As shown, the method specifically comprises the following steps:

[0081] S210, obtaining positioning card trajectory data collected by at least one positioning substation within the target time range. The positioning card trajectory data is based on data collected when the positioning device worn by the user working in the mine communicates with the positioning substation, and the positioning card trajectory data also includes the installation location data of the positioning substation.

[0082] S220. Determine an early warning positioning substation based on the inspection data collected by the inspection task.

[0083] In response to an event that the inspection task of the current positioning substation meets the inspection conditions, the inspection data corresponding to the current positioning substation is obtained; wherein the inspection data includes data under at least one evaluation dimension, and the evaluation dimension includes at least a communication status dimension, a test point signal strength dimension, a coverage area dimension, and a positioning accuracy dimension; when the data under the at least one evaluation dimension does not meet the corresponding preset conditions, the current positioning substation is determined to be the early warning positioning substation; wherein the data under the evaluation dimension includes communication status data, signal strength data of at least one test point associated with the current positioning substation, effective coverage area data associated with the current positioning substation, and positioning difference data of the current positioning substation.

[0084] According to the technical solution of the embodiment of the present disclosure, the early warning positioning substation is determined based on the inspection data collected by the inspection task.

[0085] The inspection task refers to the inspection cycle, inspection content, and inspection personnel in the inspection task of at least one positioning substation determined according to the project information and important attributes to which at least one positioning substation belongs.

[0086] Among them, the inspection cycle refers to the inspection cycle of each inspection item of the target positioning substation. The inspection personnel conduct regular inspections on each item according to the inspection cycle of each item. For example, according to the actual generation of the coal mine, the importance of the positioning substation is determined by the division of underground key areas / restricted areas / ordinary areas, and the type of positioning substation. The same positioning substation contains multiple inspection contents. According to the actual generation of the coal mine, the importance of each inspection content is confirmed, so as to determine a reasonable inspection cycle for each inspection content. The inspection cycle can be divided into different levels such as daily inspection, weekly inspection, monthly inspection and annual inspection.

[0087] Among them, the inspection content refers to the equipment appearance of the positioning substation, the equipment installation status of the positioning substation, the power supply of the positioning substation, the power supply line of the positioning substation, the communication and signal coverage of the positioning substation, the positioning precision and accuracy of the positioning substation, the environmental adaptability of the positioning substation, and the safety signs and warning signs of the positioning substation. For example, the inspection content includes the ambient temperature and humidity of the positioning substation.

[0088] Among them, inspection personnel refers to the inspection staff who perform the inspection tasks.

[0089] Exemplarily, for the target positioning substation, the inspection contents are determined to be the equipment appearance of the positioning substation, the equipment installation of the positioning substation, the power supply of the positioning substation, the power supply line of the positioning substation, the communication and signal coverage of the positioning substation, the positioning precision and accuracy of the positioning substation, the environmental adaptability of the positioning substation, and the safety signs and warning signs of the positioning substation. Among them, the inspection cycle of the equipment appearance of the positioning substation, the equipment installation of the positioning substation, the power supply of the positioning substation, the power supply line of the positioning substation, the environmental adaptability of the positioning substation, and the safety signs and warning signs of the positioning substation is once a day, and the inspection personnel are inspection staff A; for the inspection contents of the communication and signal coverage of the positioning substation and the positioning precision and accuracy of the positioning substation, the inspection cycle is once a month, and the inspection personnel are inspection staff B. After receiving the assigned inspection tasks, the inspection personnel enter the coal mine, and conduct inspections and tests one by one according to the contents and steps of the inspection tasks, and record the inspection results in detail. If the inspection personnel find any abnormal situation or potential problem, they will first record it and take photos for evidence. Then, if they can solve it on the spot, they will handle it immediately. If they cannot solve it immediately, they will report the abnormal data to the equipment maintenance module and send an alarm message to the equipment maintenance module.

[0090] The method also includes: in response to an event that the inspection task of the current positioning substation meets the inspection condition, obtaining the inspection data corresponding to the current positioning substation; wherein the inspection data includes data under at least one evaluation dimension, and the evaluation dimension includes at least a communication status dimension, a test point signal strength dimension, a coverage area dimension, and a positioning accuracy dimension; when the data under at least one evaluation dimension does not meet the corresponding preset conditions, determining that the current positioning substation is the early warning positioning substation. Wherein, the data under the evaluation dimension includes communication status data, signal strength data of at least one test point associated with the current positioning substation, effective coverage area data associated with the current positioning substation, and positioning difference data of the current positioning substation.

[0091] The communication status refers to the communication status between the positioning substation and the main computer, and the communication status data refers to the data corresponding to the communication status. The communication status data between the positioning substation and the main computer can be normal or abnormal.

[0092] The signal strength of the test point refers to the signal strength emitted by the positioning substation measured by the signal receiver or test equipment placed underground. The signal strength data of at least one test point associated with the current positioning substation refers to the signal strength emitted by the positioning substation measured by the test point. For example, for the target positioning substation, a signal receiver is placed 50 meters away from the positioning substation, and the signal strength emitted by the target positioning substation is measured. If the signal strength is three grids, then the signal strength data of this test point associated with the current positioning substation is three grids.

[0093] The coverage area refers to the area where the target positioning substation can collect the signal emitted by the signal receivers placed in different places underground. The area where the signal can be received is the effective coverage area of ​​the signal, and the area where the signal cannot be received is the blind area of ​​the signal. After the inspection staff measures, they mark the location of each test point on the map and identify the effective coverage area and blind area of ​​the signal, which is the effective coverage area data associated with the current positioning substation.

[0094] Among them, positioning accuracy refers to the accuracy of the trajectory of the test card or test equipment recorded by the positioning substation. Place test cards or test equipment at different locations in the mine to ensure that they can stably receive and send positioning signals, then record the positioning position of the test card or test equipment at different locations, and compare the positioning position with the actual position to calculate the positioning error and evaluate whether the positioning accuracy of the positioning substation meets the requirements. The positioning difference data of the current positioning substation is the calculated positioning error value. For example, place a test card 300 meters away from the target positioning substation in the mine to ensure that this test card stably receives and sends positioning signals, and then record the positioning position of the test card at this position as 290 meters away from the target positioning substation. Then the positioning difference data of the current positioning substation at this position is 10 meters, and evaluate whether the positioning accuracy of the positioning substation meets the requirements.

[0095] Specifically, after obtaining the inspection data corresponding to the inspection task completed by the current positioning substation, that is, the data under the evaluation dimension includes communication status data, signal strength data of at least one test point associated with the current positioning substation, effective coverage area data associated with the current positioning substation, and positioning difference data of the current positioning substation, it is evaluated whether at least one of these data does not meet the requirements. If any of the above inspection data does not meet the corresponding preset conditions, then the current positioning substation is determined to be the early warning positioning substation.

[0096] Exemplarily, the current positioning substation is assigned inspection staff to measure the communication status, test point signal strength, coverage area and positioning accuracy, and obtain the inspection data corresponding to the current positioning substation. If the positioning accuracy does not meet the requirements, the current positioning substation is determined to be the early warning positioning substation.

[0097] S230. Determine an early warning positioning substation based on the positioning substation status data.

[0098] In response to an event in which the current positioning substation automatically reports the device status, the changed status data of the current positioning substation is obtained; wherein the status data includes at least one of the following: the current positioning substation is offline, the AC power of the current positioning substation is disconnected, the clock of the current positioning substation is faulty, the card reader of the current positioning substation is faulty, the card reader of the current positioning substation is conflicting, the card reader of the current positioning substation is offline, and the device voltage of the current positioning substation is low; based on the status data, it is determined whether the current positioning substation is the early warning positioning substation.

[0099] According to the technical solution of the embodiment of the present disclosure, the early warning positioning substation is also determined based on the positioning substation status data, and the method further includes: in response to an event in which the current positioning substation automatically reports the device status, obtaining the status data of the change of the current positioning substation; wherein the status data includes at least one of the current positioning substation being offline, the current positioning substation AC power being disconnected, the current positioning substation clock being faulty, the current positioning substation card reader being faulty, the current positioning substation card reader being conflicting, the current positioning substation card reader being offline, and the current positioning substation device being under voltage; based on the status data, determining whether the current positioning substation is an early warning positioning substation.

[0100] Among them, automatic reporting of equipment status means that the target positioning substation reports its status data at a certain period. If the status data changes, it will be recorded, and if the status data does not change, it will not be recorded. For example, the target positioning substation will report its status data every 10 seconds. If its status data is normal and the last reported status data is also normal, then the data will not be recorded; if its status data is a positioning substation clock failure, and the last reported status data is also normal, then the data will be recorded and recorded in the equipment maintenance module.

[0101] Among them, the positioning substation is not online means that the positioning substation cannot connect to the server and is now offline.

[0102] The AC power disconnection of the positioning substation refers to the disconnection of the positioning substation from the connected AC power. At this time, the positioning substation switches to battery power supply.

[0103] Among them, the positioning substation clock failure refers to problems with the GPS clock or Beidou synchronization clock, resulting in time asynchrony or reduced accuracy.

[0104] Among them, the positioning substation card reader failure refers to the card reader in the positioning substation failing to work properly, resulting in the inability to accurately read or transmit the location information of personnel or assets.

[0105] Among them, the positioning substation reader conflict refers to the situation where when multiple readers work at the same time, the information they receive conflicts, resulting in information overlap or errors.

[0106] Among them, the offline card reader of the positioning substation refers to the state in which the card reader cannot communicate normally with the system or other devices. This situation usually leads to the inability to monitor and obtain relevant data in real time, affecting the normal operation and management of the system.

[0107] Among them, low voltage of the positioning substation equipment means that the voltage output of the power supply is lower than the normal value. This situation is usually caused by a variety of reasons, including power supply system failure, transmission line problems, transformer or distribution equipment problems, excessive power load, power system scheduling and other factors.

[0108] Specifically, the target positioning substation automatically reports the equipment status and obtains the status data changed by the target positioning substation. If at least one abnormal status data is reported by the target positioning substation, the target positioning substation is determined to be an early warning positioning substation, and the data is recorded and recorded in the equipment maintenance module.

[0109] For example, the target positioning substation reports its status data at 15:30:20, and the status data is that the positioning substation card reader is offline, and the status data reported at 15:30:10 is normal, then the current positioning substation is determined to be an early warning positioning substation, and the status data is recorded and recorded in the equipment maintenance module.

[0110] S240: Delete the positioning card track data associated with the early warning positioning substation to obtain the positioning card track data to be screened.

[0111] The data constraint conditions include eliminating the positioning card trajectory data collected by the preset positioning substation, preprocessing the positioning card trajectory data according to the early warning positioning substation received within the target time range and the data constraint conditions to obtain the trajectory data to be applied, deleting the positioning card trajectory data associated with the early warning positioning substation, and obtaining the positioning card trajectory data to be screened.

[0112] The technical solution of the embodiment of the present disclosure includes data constraints including excluding the positioning card trajectory data collected by the preset positioning substation, pre-processing the positioning card trajectory data according to the early warning positioning substation received within the target time range and the data constraints to obtain the trajectory data to be applied, including: deleting the positioning card trajectory data associated with the early warning positioning substation to obtain the positioning card trajectory data to be screened; and eliminating the positioning card trajectory data to be screened according to the positioning card trajectory data collected by the preset positioning substation in the data constraints to obtain the trajectory data to be applied.

[0113] Among them, the preset positioning substation refers to a positioning substation that is not located underground and a positioning substation of the type of regional positioning station.

[0114] The positioning card trajectory data to be screened refers to the trajectory data obtained after deleting the positioning card trajectory data associated with the early warning positioning substation.

[0115] Specifically, for the trajectory data within the target time range collected by the target positioning substation, the positioning card trajectory data is first processed according to the early warning positioning substation received within the target time range to obtain the positioning card trajectory data to be screened; then, for the positioning card trajectory data to be screened, the trajectory data of the positioning substation that is not located underground and the positioning substation of the type of regional positioning station are eliminated. After eliminating the trajectory data within the target time range collected by the target positioning substation, the trajectory data to be applied is obtained.

[0116] Exemplarily, the target positioning substation is a positioning substation located underground and is a precise positioning substation. This positioning substation does not receive an early warning within the target time range, that is, it is not an early warning positioning substation. Then the positioning card trajectory data of this positioning substation is the trajectory data to be applied.

[0117] S250, excluding the positioning card trajectory data collected by the preset positioning substation in the data constraint condition, the positioning card trajectory data to be screened is processed to obtain the trajectory data to be applied.

[0118] The positioning card trajectory data collected by the preset positioning substation is excluded from the data constraint conditions, and the positioning card trajectory data to be screened is eliminated to obtain the trajectory data to be applied.

[0119] S260: Determine a target faulty device according to the trajectory data to be applied and at least one pre-set warning constraint condition, wherein the target faulty device includes a positioning substation with a fault and / or a positioning device worn by the operating user.

[0120] The technical solution of the disclosed embodiment is to obtain the positioning card trajectory data collected by at least one positioning substation within the target time range, wherein the positioning card trajectory data is based on the data collected when the positioning device worn by the user working in the mine communicates with the positioning substation, and the positioning card trajectory data also includes the installation position data of the positioning substation, and then, according to the early warning positioning substation and data constraints received within the target time range, the positioning card trajectory data is pre-processed to obtain the trajectory data to be applied, and finally, according to the trajectory data to be applied and at least one pre-set early warning constraint, the target faulty device is determined, wherein the target faulty device includes the positioning substation with a fault and / or the positioning device worn by the working user. According to the trajectory data and early warning constraints, the operating status of the positioning substation and the positioning card is monitored and warned in a timely manner, the faulty positioning substation and positioning card are determined and repaired, and the safety of the operating personnel is improved.

[0125] Figure 6 FIG. 1 is a schematic diagram of a maintenance method for determining a fault based on a warning constraint condition provided by an embodiment of the present disclosure. Figure 6 As shown, based on the data to be applied and at least one pre-set early warning constraint condition, after determining that the target faulty equipment is a positioning substation, first retrieve the video surveillance near the positioning substation to verify the fault, and then contact the corresponding shift leader to go to the site for a second verification. After the shift leader has verified it twice, if it is determined that there is no fault, then close the early warning information; if the shift leader has verified it twice and it is determined to be a fault, then push the alarm message to the equipment maintenance module, the equipment maintenance module dispatches a work order to arrange personnel for maintenance, and the maintenance personnel close the work order after the maintenance is completed.
