[0034] In the embodiment of this application, the shaft 6, as a passage connecting the underground and the ground of the mine and also the passage for the cage 5 to run, can be provided with a shaft monitoring device 1 for monitoring the shaft 6 on the cage 5. For example, the shaft monitoring device 1 can be installed outside or inside the cage 5. In this way, during the process of the cage 5 ascending and descending in the shaft 6, the shaft monitoring device 1 can ascend and descend in the shaft 6 together with the cage 5.

[0038] In the embodiments of the present application, information interaction between the inside of the wellbore 6 and the ground can be realized by means of wireless communication. A wireless communication device 3 can be set, and a part of the wireless communication device 3 is arranged inside the wellbore 6 to establish a wireless network inside the wellbore 6, and this part of the wireless communication device 3 is communicatively connected to the ground (outside the wellbore 6). Another part of the wireless communication device 3 can be arranged on the cage 5, and the two parts of the wireless communication device 3 respectively installed on the cage 5 and in the wellbore 6 are adapted to each other and can perform data transmission.

[0039] In the embodiments of the present application, a control and analysis device 4 can be set, and the wireless communication device 3 can be communicatively connected to the control and analysis device 4. That is, the control and analysis device 4 is arranged on the ground, and the fixed part of the wireless communication device 3 arranged in the wellbore 6 is communicatively connected to the control and analysis device 4 through a wireless network or a cable. In this way, data transmission between the monitoring device in the wellbore 6 and the control and analysis device 4 can be realized, and data transmission between the monitoring device of the cage 5 and the control and analysis device 4 can also be realized.

[0040] Exemplarily, the control and analysis device 4 can be configured to be capable of receiving the real-time environmental information and real-time status information uploaded by the monitoring device in the wellbore 6 and the monitoring device of the cage 5, and the control and analysis device 4 can also be configured to be capable of sending control instructions to the monitoring device in the wellbore 6 and the monitoring device of the cage 5, and the monitoring device in the wellbore 6 and the monitoring device of the cage 5 execute corresponding preset actions in response to the received control instructions.

[0041] In another example, the control and analysis device 4 can be configured to be capable of determining whether the equipment in the wellbore 6 is normal, whether the air quality in the wellbore 6 is qualified, whether the temperature, humidity, etc. in the wellbore 6 are within a suitable range, etc. based on the received real-time environmental information. The control and analysis device 4 can also be configured to be capable of determining whether the equipment in the cage 5 is in the correct position, whether the items in the cage 5 move undesirably, etc. based on the received real-time status information. For example, the control and analysis device 4 can be configured to determine the monitoring results of the cage 5 and the wellbore 6 by means of image analysis, judgment of data size, etc.

[0042] The cage monitoring and protection system provided by the embodiments of the present application can set the shaft monitoring device 1 on the cage 5, so that the shaft monitoring device 1 can move to various positions in the shaft 6 as the cage 5 ascends and descends in the shaft 6, thereby obtaining real-time environmental information of various positions in the shaft 6 through the shaft monitoring device 1. And a cage monitoring device 2 that can be installed on the cage 5 is provided, and the real-time status information of the cage 5 can be obtained through the cage monitoring device 2, so as to realize the real-time monitoring of the shaft 6 and the cage 5. Moreover, a wireless communication device 3 that can be installed on the shaft 6 and the cage 5 is provided, and data transmission and communication between the shaft monitoring device 1, the cage monitoring device 2 and the ground in real time can be realized through the wireless communication device 3. At the same time, a control and analysis device 4 is provided, and the control and analysis device 4 can use the obtained real-time environmental information and real-time status information to determine whether the operation of the cage 5 is normal, and determine whether the equipment and environment in the shaft 6 are normal, so as to realize the prediction of failure risks, and thus is beneficial to improving the safety of the cage 5 and the shaft 6.

[0043] In some possible embodiments of the present application, as Figure 1 and Figure 2 shown, the wireless communication device 3 includes a first base station 31, a second base station 32 and a third base station 33; the first base station 31 is used to be installed at the upper shaft opening of the shaft 6 and is communicatively connected to the control and analysis device 4; the second base station 32 is used to be installed on the cage 5 and is communicatively connected to both the cage monitoring device 2 and the shaft monitoring device 1; the third base station 33 is used to be installed at the lower shaft opening of the shaft 6 and is communicatively connected to the control and analysis device 4, and the second base station 32 is communicatively connected to at least one of the first base station 31 and the third base station 33.

[0044] In the embodiments of the present application, the wireless communication device 3 can be set to a structure including multiple base stations. For example, three base stations can be set, and the three base stations are respectively set on the shaft 6 and the cage 5. The three base stations can adopt adapted 5G base stations, 4G base stations, etc.

[0045] Exemplarily, as Figure 1 shown, the first base station 31 can be set at the upper shaft opening of the shaft 6 (the part of the shaft 6 close to the ground), and the first base station 31 can be communicatively connected to the control and analysis device 4 through a cable. The third base station 33 can be set at the lower shaft opening of the shaft 6 (the part of the shaft 6 close to the mine operation area). In this way, the first base station 31 and the third base station 33 can form a stable wireless network signal in the shaft 6. For example, both the first base station 31 and the third base station 33 can adopt 5G base stations.

[0046] Another example, as Figure 2As shown in the figure, a second base station 32 that matches both the first base station 31 and the third base station 33 can be set on the cage 5. For example, the second base station 32 can be installed on the upper disk 51 of the cage 5 of the cage 5, and the second base station 32 can adopt a 5G base station. The shaft monitoring device 1 and the cage monitoring device 2 can both be communicatively connected to the second base station 32 through cables. In this way, when the cage 5 is lifted or lowered in the shaft 6 or parked in the shaft 6, no matter where the cage 5 is in the shaft 6, the second base station 32 can establish a communication connection with at least one of the first base station 31 and the third base station 33, so that the shaft monitoring device 1 and the cage monitoring device 2 can establish a communication connection with the control and analysis device 4 on the ground.

[0047] In the above embodiment, since the wireless communication device 3 adopts multiple base stations, any position in the shaft 6 can be covered by continuous wireless network signals, so that the risk of signal blind spots or disconnections in the shaft 6 can be reduced, and thus the real-time performance and stability of data transmission between the shaft 6 and the ground can be improved.

[0048] In some possible embodiments of the present application, as Figure 3 shown, the real-time environmental information includes the first image of the shaft 6; the shaft monitoring device 1 includes a first acquisition component 11, the first acquisition component 11 is arranged on the cage 5 and communicatively connected to the second base station 32, and the first acquisition component 11 is used to acquire the first image.

[0049] In the embodiment of the present application, the first acquisition component 11 can be set in the shaft monitoring device 1. For example, the first acquisition component 11 can be installed on the upper disk 51 of the top of the cage 5. The first acquisition component 11 can adopt a high-definition wide-angle camera or other devices capable of acquiring images to obtain the first image of the shaft 6 by using the first acquisition component 11.

[0050] Exemplarily, the first acquisition component 11 can be communicatively connected to the second base station 32 installed on the cage 5, such as communicatively connecting the first acquisition component 11 and the second base station 32 by cables.

[0051] In the above embodiment, since the shaft monitoring device 1 includes the first acquisition component 11, the first image of the equipment in the shaft 6 can be obtained through the first acquisition component 11, so as to facilitate timely knowing whether the state and position of the equipment in the shaft 6 are normal. And by communicatively connecting the first acquisition component 11 and the second base station 32, the first image acquired by the first acquisition component 11 can be transmitted to the control and analysis device 4 in time.

[0052] In some possible embodiments of the present application, as Figure 3As shown, the shaft monitoring device 1 further includes a supplementary lighting component 12. The supplementary lighting component 12 is arranged at a position on the cage 5 adjacent to the first acquisition component 11, and the lighting area of the supplementary lighting component 12 on the shaft 6 covers the shooting area of the first acquisition component 11.

[0053] In the embodiment of the present application, the light in the shaft 6 is usually dim. A supplementary lighting component 12 can be set for the first acquisition component 11 to illuminate the shooting area of the first acquisition component 11 through the supplementary lighting component 12.

[0054] Exemplarily, the supplementary lighting component 12 can be a light-emitting diode (LED), etc. The supplementary lighting component 12 can be arranged at a position on the upper disc 51 of the cage adjacent to the first acquisition component 11, and the lighting area of the supplementary lighting component 12 can be at least consistent with the shooting area of the first acquisition component 11, or the lighting area of the supplementary lighting component 12 can be larger than the shooting area of the first acquisition component 11. In this way, the lighting area of the supplementary lighting component 12 can completely cover the shooting area of the first acquisition component 11.

[0055] In the above embodiment, since the supplementary lighting component 12 is provided for the first acquisition component 11, the shooting area of the first acquisition component 11 can be illuminated through the supplementary lighting component 12, so that the shooting area of the first acquisition component 11 has uniform brightness, which is conducive to obtaining a clear first image in the shaft 6, and further improves the accuracy of the state judgment of the equipment in the shaft 6.

[0056] In some possible embodiments of the present application, as Figure 3 shown, the shaft monitoring device 1 includes a sensor component 13. The sensor component 13 is communicatively connected to the second base station 32 and is used to obtain at least one of the following real-time environmental information in the shaft 6: temperature, humidity, concentration of harmful gases, noise, and dust concentration.

[0057] In the embodiment of the present application, the environment in the shaft 6 is usually relatively harsh, and the environment in the shaft 6 has a great impact on both the equipment and personnel in the shaft 6. A sensor component 13 including multiple sensors can be set in the shaft monitoring device 1 to monitor whether the environment in the shaft 6 is qualified by using the sensors.

[0058] Exemplarily, a temperature sensor and a humidity sensor can be arranged in the sensor assembly 13 to collect temperature data and humidity data in the wellbore 6 by using the temperature sensor and the humidity sensor. Detection sensors for toxic and harmful gases such as a carbon monoxide detection sensor, a nitrogen dioxide detection sensor, and a sulfur dioxide detection sensor can also be arranged in the sensor assembly 13 to detect the concentration of toxic and harmful gases in the wellbore 6 in real time. A dust detector for detecting the dust concentration and a decibel meter for detecting the noise level can also be arranged in the sensor assembly 13. Each detection device in the sensor assembly 13 can be communicatively connected to the second base station 32, so that the real-time environmental information detected by the detection device can be transmitted to the control and analysis device 4.

[0059] Another example is, for example, Figure 3 As shown, a storage unit 14 can also be arranged in the wellbore monitoring device 1. The storage unit 14 can adopt a structure including a Secure Digital Card, and the storage unit 14 is communicatively connected to the second base station 32. The storage unit 14 can be configured to receive the first image and data of various real-time environmental information collected by the sensor assembly 13, and the storage unit 14 can be configured to upload the first image and data of various real-time environmental information to the control and analysis device 4 through the second base station 32.

[0060] In the above embodiment, since the sensor assembly 13 is arranged in the wellbore monitoring device 1, environmental information such as the temperature, humidity, harmful gas concentration, noise, and dust concentration in the wellbore 6 can be obtained through the sensor assembly 13. And the sensor assembly 13 is communicatively connected to the second base station 32, so that real-time monitoring of various environmental parameters in the wellbore 6 can be realized.

[0061] In some possible embodiments of the present application, the real-time status information includes the first real-time position status of the cage door 52 of the cage 5; the cage monitoring device 2 includes a first position sensor 21, and the first position sensor 21 is arranged at a position corresponding to the cage door 52 on the cage 5 and is communicatively connected to the second base station 32 for obtaining the first real-time position status, and the first real-time position status represents the position of the cage door 52 relative to the cage 5.

[0062] In the embodiments of the present application, as Figure 2 shown, the cage 5 is usually provided with a cage door 52 to close or open the cage 5 through the cage door 52. The position where the cage door 52 is located is of great significance for the safe operation of the cage 5.

[0063] Exemplarily, a first position sensor 21 can be provided for each cage door 52 of the cage 5. For example, a contact switch, a laser sensor, a Hall sensor, etc. can be used. A first position sensor 21 can be provided when the cage door 52 is in the open position, and a first position sensor 21 can be provided when the cage door 52 is in the closed position. In this way, it can be detected by the first position sensor 21 whether the cage door 52 is fully opened or fully closed. Each first position sensor 21 can be communicatively connected to the second base station 32 by a cable.

[0064] In the above embodiment, since the first position sensor 21 is provided in the cage monitoring device 2, it can be detected by the first position sensor 21 whether the cage door 52 of the cage 5 is in the normal open position or closed position, thereby improving the safety of the operation of the cage 5 and the safety of the items and personnel in the cage 5.

[0065] In some possible embodiments of the present application, the real-time status information includes the second real-time position status of the cage arrester 53 of the cage 5; the cage monitoring device 2 includes a second position sensor 22, and the second position sensor 22 is provided at a position corresponding to the cage arrester 53 on the cage 5 and is communicatively connected to the second base station 32 for obtaining the second real-time position status, and the second real-time position status characterizes the position attitude of the cage arrester 53.

[0066] In the embodiments of the present application, as Figure 2 shown, the cage 5 is usually provided with a cage arrester 53. When abnormal conditions occur during the lifting and lowering of the cage 5 in the shaft 6, such as motor failure, power failure, etc., the cage arrester 53 can prevent the cage 5 from falling in time, which is of great significance to the safety of personnel and the cage 5.

[0067] Exemplarily, a second position sensor 22 can be provided for each cage arrester 53 of the cage 5. For example, a contact switch, a laser sensor, a Hall sensor, etc. can be used. The second position sensor 22 can be provided on the parts of the cage arrester 53 that can move. In this way, it can be detected by the second position sensor 22 whether the cage arrester 53 is normally in the closed state or whether the cage arrester 53 is in the open state to determine whether the cage arrester 53 is in the expected position attitude. The second position sensor 22 can be communicatively connected to the second base station 32 by a cable.

[0068] In the above embodiment, since the second position sensor 22 is provided in the cage monitoring device 2, it can be detected by the second position sensor 22 whether the cage arrester 53 of the cage 5 is in the desired position attitude, thereby improving the safety of the operation of the cage 5 and the safety of the items and personnel in the cage 5.

[0069] In some possible embodiments of the present application, the real-time status information includes a second image inside the cage 5; the cage monitoring device 2 includes a second acquisition component 23, the second acquisition component 23 is arranged inside the cage 5 and is communicatively connected to the second base station 32, and the second acquisition component 23 is used for acquiring the second image.

[0070] In the embodiments of the present application, the second acquisition component 23 can be arranged in the cage monitoring device 2.

And by communicatively connecting the second acquisition component 23 and the second base station 32, the second image acquired by the second acquisition component 23 can be transmitted to the control and analysis device 4 in a timely manner.

[0073] In some possible embodiments of the present application, the cage monitoring device 2 further includes a signal control component 24, the signal control component 24 is communicatively connected to the first position sensor 21, the second position sensor 22, the second acquisition component 23 and the second base station 32 respectively, and the signal control component 24 is used for processing the first real-time position status, the second real-time position status and the second image, and sending the processed first real-time position status, second real-time position status and second image to the control and analysis device 4.

[0074] In the embodiments of the present application, the signal control component 24 can be arranged in the cage monitoring device 2, and the signal control component 24 can adopt a device that can send and receive data. The first position sensor 21, the second position sensor 22 and the second acquisition component 23 can be communicatively connected to the signal control component 24 by using a cable, and the signal control component 24 can be communicatively connected to the second base station 32 by using a cable.

[0075] Exemplarily, the signal control component 24 can be configured to process data such as the first real-time position state, the second real-time position state, and the second image used. For example, the data such as the first real-time position state, the second real-time position state, and the second image can be preliminarily screened to eliminate abnormal data. The data such as the first real-time position state, the second real-time position state, and the second image can also be uploaded to the control and analysis device 4 through the wireless communication device 3 at different frequencies.

[0076] In the above embodiment, since the signal control component 24 is provided for the first position sensor 21, the second position sensor 22, the second acquisition component 23, etc., the data such as the first real-time position state, the second real-time position state, and the second image can be processed through the signal control component 24, and the data such as the first real-time position state, the second real-time position state, and the second image can be uploaded to the control and analysis device 4 through the signal control component 24, so that each device in the cage 5 monitoring device can work in coordination.

[0077] In some possible embodiments of the present application, as Figure 1 shown, the monitoring result includes at least one of a monitoring report and a fault risk report; the control and analysis device 4 includes an analysis server 41; the analysis server 41 is configured to process the real-time environment information and the real-time state information based on an image recognition algorithm to generate a monitoring report of the cage 5 and / or the shaft 6; and / or, the analysis server 41 is configured to process the real-time environment information and the real-time state information based on historical data to generate a fault risk report; the historical data includes the historical environment information of the shaft 6 and the historical state information of the cage 5.

[0079] Exemplarily, an image recognition algorithm can be configured for the analysis server 41, and the image recognition algorithm can adopt a convolutional neural network, an object detection algorithm, etc. Then, the first image, the second image, etc. can be recognized through the image recognition algorithm to determine whether the equipment and structures in the shaft 6 and the cage 5 are normal. If it is determined that the equipment and structures in the shaft 6 and the cage 5 are in a state different from the expected state, a corresponding monitoring report can be generated.

[0080] In another example, some historical data of the shaft 6 and the cage 5 can be stored in the analysis server 41. The analysis server 41 is configured to compare the received real-time environmental information and real-time status information with the stored historical data. For example, when the dust concentration data in the real-time environmental information is greater than the dust concentration range in the historical environmental information, a dust over-standard risk report can be generated. When the harmful gas concentration data in the real-time environmental information is greater than the harmful gas concentration range in the historical environmental information, a harmful gas over-standard risk report can be generated. When the first real-time position status in the real-time status information is different from the preset value in the historical status information, a fault risk report of the cage door 52 can be generated. When the second real-time position status in the real-time status information is different from the preset value in the historical status information, a fault risk report of the car arrester 53 can be generated.

[0081] In yet another example, the analysis server 41 can be configured to generate corresponding preventive maintenance suggestion reports according to different risk reports. For example, suggestions on maintenance measures that can be taken for different risks can be stored in the analysis server 41. Then, the analysis server 41 can be made to call the suggestions on maintenance measures according to different risk reports and generate preventive maintenance suggestion reports.
