Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.

At present, the topological relation between an open mine power supply station and a line is mainly recorded in an Excel table by manual operation, the situation that the updating content is not timely and visual exists, and the two-ticket flow is realized in an off-line mode, so that the operation efficiency is affected. And, the staff needs to spend a large amount of time to read, contrast and inquire the data in the Excel form to confirm the working condition of the mine power supply system, and arrange the maintainer to carry out corresponding maintenance and maintenance work to the mine power supply system according to the actual running condition of the mine power supply system.

However, in the manner of data display in the form of a table or the like, a large amount of time is required to be consumed by workers to read data when the workers develop work, so that the work arrangement of a mine power supply system is not timely, the work requirement after the scale of the mine power supply system is greatly increased is difficult to meet, in addition, the problem of power failure/power-on line error possibly exists, and the work safety of the workers is threatened.

Aiming at the problems, the embodiment of the application mainly provides a device monitoring method, a device, equipment and a medium in a mine power supply system.

The following describes a device monitoring method, a device and equipment in a mine power supply system according to an embodiment of the application with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a device monitoring method in a mine power supply system according to an embodiment of the application.

The embodiment of the disclosure is exemplified by the device monitoring method being configured in a device monitoring apparatus, and the device monitoring apparatus can be applied to any electronic device, so that the electronic device can execute a device monitoring function.

The electronic device may be any device with computing capability, for example, a PC (Personal Computer ), a mobile terminal, a server, and the like, and the mobile terminal may be, for example, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and the like, which have hardware devices with various operating systems, touch screens, and/or display screens.

As shown in fig. 1, the device monitoring method in the mine power supply system may include the steps of:

step 101, acquiring a power supply topological graph corresponding to a mine power supply system.

In the embodiment of the application, the connection relation between each transformer substation and each electric equipment in the mine power supply system can be determined, the connection relation is marked as a first connection relation in the application, and the upper and lower level relation between each transformer substation and each electric equipment is determined, so that in the application, a power supply topological graph can be generated according to the first connection relation between each transformer substation and each electric equipment in the mine power supply system and the upper and lower level relation between each transformer substation and each electric equipment.

The electric equipment can comprise mining equipment (such as an electric shovel, an electric pick and the like), transportation equipment, lighting equipment, heat dissipation equipment and the like. It should be noted that the electric device may also include other devices, for example, the electric device may also include a camera, a radar, a crusher, and the application is not limited thereto.

It should be noted that, the foregoing power supply topology diagram includes the transformer substation and the electric equipment, but the application is not limited thereto, and in practical application, the power supply topology diagram may also include other devices, for example, the power supply topology diagram may also be generated according to a transformer substation, where the transformer substation is connected with each transformer substation, and each transformer substation is connected with each electric equipment.

For example, the substation may be used as a first-stage node in the power supply topology, the substation may be used as a second-stage node in the power supply topology, and the electric device may be used as a third-stage node in the power supply topology.

Step 102, operation information and energy consumption information of each transformer substation and each electric equipment in the power supply topological graph are obtained.

In the embodiment of the application, the operation information may include operation data such as voltage and current.

In the embodiment of the application, the energy consumption information can comprise the energy consumption data of electric quantity consumed by a transformer substation or electric equipment, accessory oil (comprising gasoline, industrial gear oil, hydraulic transmission oil, engine oil, hydraulic oil, general lubricating grease and the like), cables, steel wire ropes and the like.

In the embodiment of the application, the operation information and the energy consumption information of each transformer substation and each electric equipment in the power supply topological graph can be acquired through the data acquisition equipment.

And step 103, if it is determined that at least one first device in each transformer substation and each electric equipment is abnormal in operation or energy consumption according to the operation data and the energy consumption data, determining a second device positioned at the lower level of the first device from the power supply topological graph.

In the embodiment of the application, the first device can be any one device of each transformer substation and each electric device. The number of the first devices may be one or may be plural, which is not limited in the present application.

In the embodiment of the disclosure, the energy consumption information may include multiple parameters, each parameter in the energy consumption information of any device in each transformer substation and each electric device may be compared with a corresponding threshold, and when the value of a certain parameter is greater than the corresponding threshold, it may be determined that the energy consumption of any device is abnormal.

For example, the energy consumption information includes the electric quantity consumed by any one device and the auxiliary oil, so that whether the electric quantity consumed by any one device is higher than a set electric quantity threshold value can be judged, if yes, the power consumption abnormality of any one device is determined, and whether the auxiliary oil consumed by any one device is higher than the set threshold value can be judged, if yes, the oil consumption abnormality of any one device is determined.

Similarly, the operation information can also include multiple parameters, each parameter in the operation information of any one device in each transformer substation and each electric device can be compared with a corresponding threshold range, and when the value of one parameter is not in the corresponding threshold range, abnormal operation of any one device can be determined.

For example, taking the operation information including the current and the voltage as an example, it may be determined whether the current in the operation information of any device is within a set current threshold range, where the current threshold range may be [ current threshold lower limit, current threshold upper limit ], and when the current is not within the current threshold range, it is determined that any device is abnormal, and similarly, it may be determined whether the voltage in the operation information of any device is within a set voltage threshold range, where the current threshold range may be [ voltage threshold lower limit, voltage threshold upper limit ], and when the voltage is not within the voltage threshold range, it is determined that any device is abnormal.

In the embodiment of the disclosure, in the case that it is determined that at least one first device in each substation and each electric device is abnormal in operation or energy consumption according to the operation data and the energy consumption data, in order to facilitate related personnel to learn an influence range of the abnormality, a second device located at a lower stage of the first device may be further determined from a power supply topological graph.

And 104, carrying out anomaly labeling on the first equipment and the second equipment in the power supply topological graph so as to prompt the anomaly investigation on the first equipment and the second equipment.

In the embodiment of the disclosure, the first device with the abnormality and the second device located at the lower stage of the first device can be marked with the abnormality in the power supply topological graph so as to prompt the abnormality investigation of the first device and the second device. Therefore, the first equipment with the abnormality in the power supply topological graph can be marked with the abnormality at present, the second equipment which is positioned at the lower stage of the first equipment can be predicted to be abnormal, and the second equipment which is to be abnormal is marked with the abnormality in the power supply topological graph, so that related personnel can know the influence range of the abnormality conveniently, and the related personnel can overhaul and maintain the abnormal equipment in time.

For example, when the first device is a certain device in a substation, if the first device is abnormally operated, such as over-voltage or over-current, it may cause a fault of electric equipment connected to the substation.

As an example, the first device and the second device may be marked for anomalies by different marking means, so that the relevant person distinguishes the first device with the current anomaly from the second device with the impending anomaly.

For example, the first device and the second device may be marked with an abnormality by different colors, for example, the first device may be marked with a red color and a high brightness, and the second device may be marked with a yellow color, so that a person can distinguish between a device with a current abnormality and a device with an abnormality about to occur.

Further, under the condition that the first equipment is abnormal in operation or energy consumption, prompt information can be sent, and the prompt information is used for prompting the first equipment to be abnormal in energy consumption and/or operation, and in addition, the prompt information can be also used for prompting the second equipment to be abnormal.

In order to clearly illustrate the above embodiments, the present disclosure also proposes an apparatus monitoring method.

Fig. 2 is a flow chart of a device monitoring method in a mine power supply system according to a second embodiment of the present application.

As shown in fig. 2, the device monitoring method in the mine power supply system may include the steps of:

step 201, obtaining a power supply topological graph corresponding to a mine power supply system.

Step 202, operation data, energy consumption data and state information of each transformer substation and each electric equipment in a power supply topological graph are obtained.

The execution of steps 201 to 202 may refer to the execution of any embodiment of the present application, and will not be described herein.

In an embodiment of the present application, the state information may include a power-on state, a power-off state, a switch from a power-off state to a power-on state, or a switch from a power-on state to a power-off state.

In the embodiment of the disclosure, the operation data, the energy consumption data and the state information of each transformer substation and each electric equipment can be collected through the data collecting equipment.

And 203, marking state information, operation information and energy consumption information of each transformer substation and each electric equipment on the power supply topological graph.

In the embodiment of the disclosure, in order to facilitate a worker to intuitively acquire the power supply state of the mine power supply system and the working state of each device in the mine power supply system, state information, operation information and energy consumption information of each transformer substation and each electric device can be marked in a power supply topological graph.

And 204, if it is determined that at least one first device in each transformer substation and each electric equipment is abnormal in operation or energy consumption according to the operation data and the energy consumption data, determining a second device positioned at the lower level of the first device from the power supply topological graph.

And 205, carrying out anomaly labeling on the first equipment and the second equipment in the power supply topological graph so as to prompt the anomaly investigation on the first equipment and the second equipment.

The execution of steps 204 to 205 may refer to the execution of any embodiment of the present application, and will not be described herein.

It should be noted that the execution timing of steps 204 to 205 is not limited in the present application, and steps 204 to 205 are merely executed after step 203, and steps 204 to 205 may be executed in parallel with step 203 or steps 204 to 205 may be executed before step 203 in practical application.

The power-off state and the power-on state of the equipment in the mine power supply system are related to the safety of mine production operation, and when the state of the equipment in the mine power supply system is switched, for example, the equipment is switched from the power-on state to the power-off state, or the equipment is switched from the power-off state to the power-on state, a worker needs to be prompted.

Therefore, in one possible implementation manner of the embodiment of the present application, whether the state of at least one third device in each transformer substation and each electric device is switched may be further determined according to the state information of each transformer substation and each electric device, for example, when the state information of the third device is switched from the power-off state to the power-on state, or when the state information of the third device is switched from the power-on state to the power-off state. And when at least one third device is subjected to state switching, the first prompt information can be sent, and/or the third device is abnormally marked in the power supply topological graph, wherein the first prompt information is used for prompting the third device to be subjected to state switching.

Wherein the third device may be the same as the first device or may be different, as the application is not limited in this regard.

According to the equipment monitoring method in the mine power supply system, the state information, the operation information and the energy consumption information of the equipment in the power supply topological graph are visually displayed, so that workers can intuitively know the power supply state of the mine power supply system and the working state of each equipment in the mine power supply system, and the working efficiency of the workers can be improved.

It should be noted that, for the mine power supply system, along with the position change of the electric equipment (such as mining equipment), the electric equipment may need to be connected with different substations, and at this time, in order to facilitate the staff to accurately know the power supply state of the mine power supply system, the power supply topology map may be updated. The above process will be described in detail with reference to fig. 3.

Fig. 3 is a schematic flow chart of a device monitoring method in a mine power supply system according to a third embodiment of the present application.

As shown in fig. 3, on the basis of the embodiment shown in fig. 1 or fig. 2, the device monitoring method in the mine power supply system may further include the following steps:

step 301, acquiring data acquired by a data acquisition device, and determining at least one cable-connected transformer substation and electric equipment according to the data.

In the embodiment of the application, the transformer substation and the electric equipment which are respectively connected with the two ends of each cable can be monitored in real time through the data acquisition equipment.

As an example, the data acquisition device may include a plurality of cameras, and the substation and the electric equipment connected by each cable may be determined by image data acquired by the plurality of cameras.

As another example, the data collection data may include a camera and an RFID (Radio Frequency Identification ) device, an RFID tag may be disposed on the cable, the RFID tag on the cable may be identified by the RFID device to determine whether the position of the cable is changed, and in the case that the position of the cable is changed, the image data collected by the camera may be combined to determine whether the substation and the electric equipment connected by the cable are changed.

Step 302, determining whether the first connection relationship is changed according to at least one cable-connected substation and electric equipment.

In the embodiment of the application, whether the first connection relationship between each transformer substation and each electric equipment in the power supply topological graph is changed can be determined according to the transformer substations and the electric equipment connected by each cable.

And step 303, updating the power supply topological graph according to the transformer substation and the electric equipment connected by at least one cable in response to the change of the first connection relation.

In the embodiment of the application, under the condition that the first connection relation is changed, the power supply topological graph can be updated according to the transformer substations and the electric equipment connected by the cables.

For example, an electric shovel in a mining device is illustrated by using electric equipment, and in the power supply topology diagram, a cable 1 is assumed to be connected with a transformer station a and an electric shovel a, a cable 2 is assumed to be connected with a transformer station B and an electric shovel B, and since the electric shovel a and the electric shovel B continuously move in the operation process, the electric shovel B is connected with the transformer station a through the cable 1, and the electric shovel a is connected with the transformer station B through the cable 2, at this time, the power supply topology diagram can be updated according to the transformer station a and the electric shovel B connected with the cable 1, and the transformer station B and the electric shovel a connected with the cable 2. In the power supply topological graph before updating, a connection relationship exists between a transformer substation A and an electric shovel a, a connection relationship exists between a transformer substation B and an electric shovel B, and in the power supply topological graph after updating, a connection relationship exists between the transformer substation A and the electric shovel B, and a connection relationship exists between the transformer substation B and the electric shovel a.

According to the equipment monitoring method in the mine power supply system, the power supply topological graph is updated, so that a worker can accurately know the power supply state of the mine power supply system.

In a possible implementation manner of the embodiment of the application, the connection relation between each transformer substation and each electric equipment can be configured through the configuration file, so that whether the power supply topological graph is changed or not can be determined according to the configuration file, and if so, the power supply topological graph is updated. The above process will be described in detail with reference to fig. 3.

Fig. 4 is a flow chart of a device monitoring method in a mine power supply system according to a fourth embodiment of the present application.

As shown in fig. 4, on the basis of the embodiment shown in fig. 1 or fig. 2, the device monitoring method in the mine power supply system may further include the following steps:

step 401, a configuration file is obtained, wherein a second connection relation between each transformer substation and each electric equipment and a second identifier of a cable connected between each transformer substation and each electric equipment are recorded in the configuration file.

In the embodiment of the present application, the file format of the configuration file is not limited, for example, the configuration file may be in a file format such as Word, excel, etc.

In the embodiment of the present application, the identifier of the cable is used to uniquely identify the corresponding cable, for example, the identifier of the cable may be a cable number, a line number (or a branch number) where the cable is located, and so on.

In the embodiment of the application, the second connection relation between each transformer substation and each electric equipment and the second identification of the cable connected between each transformer substation and each electric equipment can be configured through the configuration file.

As an example, the Excel is an example in the file format of a configuration file, and the configuration file may include contents as shown in table 1.

TABLE 1

The coal sorting yards are used for sorting coal according to the heat value of the coal to obtain different types of coal, and placing the same type of coal in the same coal yard to obtain a plurality of sorting coal yards. The line number refers to a cable connection substation of the substation through a cable corresponding to the line number, the substation is connected with electric equipment through a cable corresponding to the branch line number, namely the branch line number is a second identifier of the cable connected between the substation and the electric equipment.

In the embodiment of the application, the configuration file can be obtained and analyzed to determine the second connection relation between each transformer substation and each electric equipment and the second identification of the cable connected between each transformer substation and each electric equipment.

And step 402, updating the power supply topological graph according to the difference between the first connection relation and the second connection relation and the difference between the first identifier and the second identifier of the cable connected between each transformer substation and each electric equipment marked on the power supply topological graph.

In the embodiment of the application, whether the second connection relation between each transformer substation and each electric equipment in the configuration file is different from the first connection relation between each transformer substation and each electric equipment in the power supply topological graph or not can be judged, and if the difference exists, the power supply topological graph is updated according to the difference.

Still referring to table 1 above for exemplary purposes, assuming that branch No. 21 connects substation No. 2 and electric shovel 1410 in the power topology, however, branch No. 21 connects only substation No. 2 in the configuration file, and no electrical device is connected, electric shovel 1410 may be removed from the power topology.

In the application, considering that the cable may be changed in the actual operation process, it may also be determined whether there is a difference between the first identifier of the cable connected between each substation and each electric device, which is marked on the power supply topology map, and the second identifier of the cable connected between each substation and each electric device in the configuration file, and if there is a difference, the power supply topology map is updated according to the difference.

Still referring to table 2, if there is no 91 branch in the power supply topology diagram and there is a 91 branch in the configuration file, the 91 branch may be added to the power supply topology diagram, and the connection relationship between the No. 9 transformer substation and the charging pile may be added, that is, the No. 9 transformer substation and the charging pile are connected through the 91 branch. For example, the updated power topology may be as shown in fig. 5.

In fig. 5, the PLC refers to a programmable logic controller (Programmable Logic Controller), the AACM is a high-reliability electromechanical integrated flexible starting system specially designed for a belt conveyor, which can effectively reduce the failure rate of a belt, a speed reducing machine and a belt carrier roller damaged by impact stress, N01 to N06 refer to a speed reducer, a coupler, a discharge arm driving roller, a discharge arm tensioning roller, a receiving arm driving roller and a receiving arm tensioning roller respectively, and TC1 to TC3 refer to a discharge trolley bend roller (upper portion), a discharge trolley bend roller (lower portion) and a discharge trolley tensioning roller respectively.

It should be noted that, in the present application, connection relations between each substation and the electric equipment can be recorded in the worksheet content in the worksheet system, and whether the power supply topology map is changed can be determined according to the worksheet content, if yes, the power supply topology map is updated. The above process will be described in detail with reference to fig. 6.

Fig. 6 is a flow chart of a device monitoring method in a mine power supply system according to a fifth embodiment of the present application.

As shown in fig. 6, on the basis of the embodiment shown in fig. 1 or fig. 2, the device monitoring method in the mine power supply system may further include the following steps:

step 501, obtaining target work order content from a work order system.

In the embodiment of the application, the target work order content can be any one of the work order contents in the work order system, for example, the target work order content can be the latest work order content in the work order system.

In the embodiment of the application, the target work order content can be acquired from the work order system of the mobile application.

Step 502, determining a third connection relation between each transformer substation and each electric equipment and a third identifier of a cable connected between each transformer substation and each electric equipment according to the content of the target work order.

In the embodiment of the application, the content of the target work order can be analyzed to determine the third connection relation between each transformer substation and each electric equipment and the third identification of the cable connected between each transformer substation and each electric equipment.

And step 403, updating the power supply topological graph according to the difference between the first connection relation and the third connection relation and the difference between the first identifier and the third identifier of the cable connected between each transformer substation and each electric equipment marked on the power supply topological graph.

In the embodiment of the application, whether the third connection relation between each transformer substation and each electric equipment in the target work order content is different from the first connection relation between each transformer substation and each electric equipment in the power supply topological graph or not can be judged, and if the third connection relation is different from the first connection relation between each transformer substation and each electric equipment in the power supply topological graph, the power supply topological graph is updated according to the difference.

For example, assuming that branch 21 in the power topology is connected to substation # 2 and power shovel 1410, whereas branch 21 in the target work order content is connected to substation # 2 only, and not to any powered device, power shovel 1410 may be removed from the power topology.

In the application, considering that the cable may be changed in the actual operation process, it may also be determined whether there is a difference between the first identifier of the cable connected between each substation and each electric device marked on the power supply topology map and the third identifier of the cable connected between each substation and each electric device in the target work order content, and if there is a difference, the power supply topology map is updated according to the difference.

For example, assuming that there is no 91 branch in the power supply topology diagram, and there is a 91 branch in the target work order content, and the 91 branch is connected to the 9 substation and the charging pile, the 91 branch may be newly added in the power supply topology diagram, and the connection relationship between the 9 substation and the charging pile is added, that is, the 9 substation and the charging pile are connected through the 91 branch.

Relevant sensors can be installed on the side of a transformer substation, electric equipment (such as an electric shovel) and a cable so as to obtain the transformer substation and the electric equipment which are connected through the cable. As shown in fig. 7, a transformer substation can be connected with an interface B of a cable through an interface a, and the electric shovel can be connected with an interface C of the cable through an interface D, and when the connection relationship between the transformer substation and the electric shovel is changed, the connection relationship between the four interfaces A, B, C, D is changed, so that in the application, a database related to the four interfaces A, B, C, D can be established for recording the connection relationship between the interfaces. The four databases of the ABCD can be updated in real time according to the content of the work order, so that the connection relation between the transformer substation and the electric shovel in the power supply topological graph is updated according to the updated databases.

It should be noted that, the safety of mine production operation is also influenced by the abnormal cable access, for example, when the cable is excavated by the excavating equipment, the situation such as leakage risk, fire disaster and the like may exist at the breakpoint, and when the cable access is abnormal, the electric equipment cannot work normally, so that the progress of mine production operation is influenced. Therefore, in the application, the access abnormality detection can be performed on the cables, and when the target cable with the access abnormality in each cable is determined, the target cable can be marked with the abnormality in the power supply topological graph, so that related personnel can repair and maintain the target cable in time. The above process will be described in detail with reference to fig. 8.

Fig. 8 is a flowchart of a device monitoring method in a mine power supply system according to a sixth embodiment of the present application.

As shown in fig. 8, on the basis of any one of the above embodiments, the device monitoring method in the mine power supply system may include the steps of:

Step 601, according to the first identification of each cable, obtaining the working parameters of each cable.

In the embodiment of the application, the working parameters of the cable can comprise parameters such as passing voltage, passing current and the like. Wherein the operating parameters of the cable can be collected by the relevant equipment.

In the embodiment of the application, for each cable in the power supply topological graph, the related equipment for acquiring the working parameters of the cable can be determined according to the first identifier of the cable, and the working parameters acquired by the related equipment are acquired.

Step 602, determining whether a target cable with abnormal access exists in each cable according to the working parameters of each cable.

In the embodiment of the application, whether the target cable with abnormal access exists in each cable can be determined according to the working parameters of each cable. For example, when the passing current in an operating parameter of a certain cable is zero, it may be determined that the cable is the target cable of the abnormal access.

And step 603, sending second prompt information in response to the existence of the target cable, and/or performing anomaly labeling on the target cable in the power supply topological graph, wherein the second prompt information is used for prompting the access anomaly of the target cable.

In the embodiment of the application, the second prompt information can be sent under the condition that the target cable with abnormal access exists in the power supply topological graph, and/or the target cable is marked with the abnormality in the power supply topological graph, wherein the second prompt information is used for prompting the abnormal access of the target cable.

As an example, a power supply topology map may be generated according to the actual situation of the mine power supply system, where the power supply topology map has kinetic energy such as real-time display, alarm pushing, manual adjustment of equipment access binding, power outage/power-on line linkage, and the like.

The operation condition of the mine power supply system, such as state information, operation information and energy consumption information of each device, can be displayed in a power supply topological graph in a graphical interface/color marking mode. In addition, the state information, the operation information and the energy consumption information of each device in the power supply topological graph can be modified manually, and the connection relation between the transformer substation and the electric equipment in the power supply topological graph can be modified manually.

When any one of the data acquisition equipment, the electric equipment and the transformer substation in the mine power supply system is in fault or abnormal, the power failure/power-on state is changed and the running state of the equipment is manually modified, relevant equipment can be marked in a power supply topological graph to prompt staff of the states of the equipment, and relevant affected equipment can be marked.

The connection state of the cable can be monitored, when the connection relation between the electric shovel and the transformer substation is changed, the change information can be input into the system (for example, the operation of updating the cable outlet/inlet equipment binding and the like) through manual verification, and the power supply topological graph is automatically updated according to the change data of the system.

The data acquisition equipment such as a transformer, an intelligent ammeter and a communication module can be additionally arranged on the power supply/electric equipment, the real-time state and energy consumption information of the power supply/electric equipment can be acquired in real time, and the information is automatically uploaded to a central server for storage; the data analysis and display can be performed according to the current/historical data to form a data analysis chart.

The power failure/power-on state of the equipment can be judged according to the real-time feedback data of the data acquisition equipment, and when the equipment state is changed, an alarm can be pushed to a supervision center in real time to remind related personnel of the change of the equipment state, wherein the power failure/power-on state is related to the safety of on-site production operation, so that the alarm level is highest. When an alarm is formed, the state switching time (including the starting time and the ending time of power failure/power-on) can be automatically recorded, and each state switching is recorded in a refined mode, so that a data base is provided for analysis statistics in the future.

The energy consumption information of the equipment can be acquired in real time through data acquisition equipment such as an intelligent ammeter, the acquisition interval is 5s (configurable), each piece of data is matched with a stored time tag, and the energy consumption information of the equipment can be displayed and analyzed according to a time line.

As an example, due to the accuracy and timeliness of alarm information of the mine power supply system, safety of on-site operators and equipment is concerned, the design of the alarm information is concise, visual and auditory fatigue of users caused by excessive alarm information can be avoided, and therefore important alarm information is ignored. In the present application, the alarm types can be categorized as shown in table 3:

TABLE 3 Table 3

The cables can be provided with positioning equipment, such as GPS (Global Position System, global positioning system), RFID and other equipment, so that the positioning equipment can acquire the position information collected by the positioning equipment, and the position of each cable in the power supply topological graph is marked. In the application, whether the cable is positioned and lost can be determined according to the data acquired by the positioning equipment, for example, when the data acquired by the positioning equipment cannot be acquired, the cable is positioned and lost can be determined. It can be understood that when the cable positioning is lost, because the specific position of the cable in the power supply topological graph cannot be determined, if the cable position is changed, on one hand, the power supply topological graph cannot be updated timely, on the other hand, the cable position is changed, and the situation of abnormal cable access is also likely to occur, at this time, the safety of mine production operation is also likely to be threatened, and therefore, the alarm level of the cable positioning loss is higher.

When the equipment is in fault, fault feedback and fault processing can be performed, wherein the fault feedback mainly comprises fault identification of the sensor and power failure/power-on troubleshooting remarks.

The data acquisition equipment acquires real-time operation data of the power supply/electric equipment in real time, when the operation data acquired by the data acquisition equipment is abnormal fault data, fault alarms can be pushed to prompt related personnel to take measures in time, overhaul operation and safety precaution measures are carried out on the related equipment, and fault recognition time can be accurately recorded for users to inquire.

The power failure/power-up alarm trigger comprises a planned power failure and a fault power failure, but after the power failure alarm trigger, a secondary manual input interface can be provided for a user, and the user can remark the reason of the power failure.

In summary, the mine power supply system in the related art relies on the manual updating Excel form of staff, presents mine power supply system's power supply state through the Excel form, work efficiency is low, and the power supply topological graph in the Excel form is not enough directly perceived, in addition, can't carry out the state control to each power supply/consumer, when equipment has a power failure, can't fix a position the investigation to the fault point fast.

In the application, the power supply topological graph can be automatically updated, the connection relation between the devices can be intuitively displayed, and the state of the devices is monitored based on the power supply topological graph, so that the power failure/power-on accident can be rapidly checked, and the working efficiency is improved. The mine power supply system can be subjected to whole-network analysis and global monitoring, and the comprehensive perceptibility and risk prejudging capability of regulation and control personnel on the running state of the power grid can be improved.

In the application, the automatic updating of the power supply topological graph can be realized, and the influence range of the power failure/power-on region is differentiated by the power supply topological graph, for example, when the electric equipment fails, the region where the electric equipment is located can be marked, for example, when the electric shovel fails, the region where the electric shovel is located can not dig coal, and the region where the electric shovel is located can be marked in the power supply topological graph, for example, red, highlight display and the like.

The state of each device can be monitored based on the power supply topological graph, and when a power failure/power-on event occurs, early warning can be performed in time.

According to the equipment monitoring method in the mine power supply system, through detecting the access abnormality of the cables, when the fact that the target cables with the access abnormality exist in each cable is determined, the target cables are marked with the abnormality in the power supply topological graph, so that related personnel can conveniently overhaul and maintain the target cables in time, and the safety of mine production operation is improved.
