Description

Technical Field

[0001] This application relates to the field of power distribution room management technology, and in particular to an intelligent AI-based rat detection system for power distribution rooms. Background Technology

[0002] A power distribution room (also known as a power distribution room or distribution chamber) is a dedicated room in a power system used for centralized distribution and control of electricity. Due to factors such as heat dissipation structures, pipes passing through walls, and personnel access, there is a chance that small animals (such as rats) and insects may enter the power distribution room. Among these, rats scurrying in and gnawing on electrical wires pose a relatively higher risk, potentially leading to large-scale power outages or fires.

[0003] Traditional methods of preventing rodents from entering the power distribution room involve installing rodent barriers at the entrance. However, if the barriers are too low, their effectiveness in preventing rodents from entering is limited. If the barriers are too high, they can cause inconvenience for staff entering and exiting the power distribution room. Furthermore, it is impossible to know whether the barriers are effective until they have already caused damage, at which point significant economic losses have already occurred. Therefore, this application proposes a new technical solution. Summary of the Invention

[0004] To address the shortcomings of rodent-proof barriers and help staff promptly detect rodent infestations in power distribution rooms, thereby reducing economic losses, this application provides an intelligent AI-based rodent detection system for power distribution rooms.

[0005] This application provides an intelligent AI-based rat detection system for power distribution rooms, employing the following technical solution:

[0006] A smart rat detection system for a power distribution room includes a control module and an infrared sensing module, a vision module, and an alarm module connected to the control module. The infrared sensing module includes several infrared sensors, with at least one sensor's detection probe facing the lower end of the door frame at the power distribution room entrance. The vision module includes several cameras, with at least one camera's image sensor facing the detection area of ​​the infrared sensors. The control module is wirelessly connected to a remote management platform. The control module is configured as follows:

[0007] If the detection signal fed back by the infrared sensor indicates that a living organism has passed by, then the video data from the camera at the current time point is extracted to generate a biological invasion video clip.

[0008] Identification of invading organisms based on video clips of biological invasion;

[0009] If the pre-selected target organism appears in the identification results, the alarm module will be controlled to trigger an alarm, and the remote management platform will send a warning message to the pre-recorded staff.

[0010] Optionally, it also includes a mobile support mechanism, which includes a track installed around the wall of the power distribution room and a mobile trolley slidably connected to the track. The mobile trolley is hinged to a bracket, and the hinge rotation surface of the bracket is perpendicular to the wall. The infrared sensor ball is hinged to the end of the bracket.

[0011] The mobile trolley is equipped with a drive unit for driving the mobile trolley to move along the track, and the drive unit is wirelessly connected to the control module;

[0012] One of the cameras is located outside the power distribution room, with the camera's image-facing end pointing towards the path leading into the power distribution room. The control module is configured as follows:

[0013] The camera outside the power distribution room is defined as the A1 camera unit;

[0014] Behavior recognition is performed on the video data from the A1 camera unit;

[0015] If the current time is within the preset opening time of the power distribution room door or if a person's behavior is detected as walking towards the power distribution room, the control drive unit will drive the mobile trolley to move to the entrance / exit door frame of the power distribution room.

[0016] The camera located in the power distribution room is defined as a B1 camera;

[0017] If the video data from the B1 camera indicates that the entrance and exit of the power distribution room are closed, the control drive unit will drive the mobile trolley to perform the inspection process.

[0018] Optionally, a synchronously rotating ultrasonic sensor is disposed to the side of the infrared sensor. The ultrasonic sensor is wirelessly connected to the control module, and the control module is electrically connected to several current sensors. Each current sensor is used to detect the current parameters of various electrical devices in the power distribution room. The control module is configured as follows:

[0019] Record the ID of each current sensor and the location of the corresponding electrical equipment, and obtain the current parameters;

[0020] If the detection signal fed back by the infrared sensor indicates that a living object of the target type has passed by, then the corresponding current parameter of the current position of the mobile car is called.

[0021] If the current parameters meet the preset ultrasonic sensor activation conditions, the mobile trolley is controlled to stop, and the signal fed back by the ultrasonic sensor is acquired. Based on the signal fed back by the ultrasonic sensor, it is determined whether a target-type living body has passed by.

[0022] If a living organism of the target type passes by, the video data from the camera at the current time point is captured to generate a biological invasion video clip.

[0025] Optionally, the track has a horizontal T-shaped cross-section, with the horizontal section connected to the wall and the other end extending to the side; the mobile trolley is equipped with multiple rollers, which are parallel to multiple side walls of the mobile trolley. The multiple rollers installed on each side wall form a group. The drive unit includes multiple units, and the output shaft of the drive unit and the central shaft of one of the rollers in each group are fixed; the outer wall of the roller abuts against the track, and multiple sections of the track near the corner of the wall have openings for the rollers to pass through. The track is also equipped with an anti-fall mechanism to prevent the mobile trolley from falling out of the openings.

[0026] Optionally, the anti-fall-off mechanism includes a limiting block and a traction rope. The track has a limiting groove located in the vertical section of the track and is excavated along the thickness direction of the track. The limiting block is slidably connected to the limiting groove. The limiting block is circular when viewed from above, and its outer wall has protrusions. The limiting groove has a groove that fits the protrusions. The ends of the traction rope are connected to the moving trolley and the limiting block, respectively.

[0027] Optionally, the track is provided with multiple position detection units that detect the direction of falling into the groove. The position detection units are wirelessly connected to the control module, and the control module is configured as follows:

[0028] Record the position of each detection unit, the track segment behind it, the detection range corresponding to each track segment, and the number of cameras matched to each detection range. Establish a one-to-one correspondence and store it in a pre-established database.

[0029] If the detection signal fed back by the infrared sensor indicates that a living target has passed by, the position of the location detection unit of the most recent feedback signal is obtained, the database is searched to obtain its corresponding orbital segment and detection range, and several cameras matched with it are obtained according to the detection range. The video data of several cameras matched at the current time node is extracted to generate a biological invasion video clip.

[0030] Optionally, the upper surface of the mobile trolley is provided with a rotating assembly, which includes a motor, a rope winder, and a pull rope wirelessly connected to the control module. The motor is mounted on the upper surface of the mobile trolley, the rope winder is circular at one end and is rotatably connected to the upper surface of the mobile trolley, the rotation direction of the rope winder is the same as the rotation direction of the bracket, the output shaft of the motor is fixed to the center of the rope winder, the pull rope is wound around the rope winder and its end is connected to the bracket, and the side of the bracket facing the wall is provided with a baffle to prevent excessive angle pulling when retracting the bracket.

The infrared sensor is installed in the hollow part of the ball, and the detection end faces downward to the side.

[0032] The connecting frame includes multiple arc-shaped pockets that are circumferentially distributed around the center of the sphere, with a gap between the pockets and the sphere for the installation of the ball bearings. The outer wall of the ball bearings abuts against both the pockets and the sphere.

[0033] The bracket is provided with a telescopic unit at the end near the sphere. The rotating wheel is fixed to the telescopic end of the telescopic unit and the telescopic unit pushes the outer wall of the rotating wheel against the sphere. The rotating wheel is connected to a second motor that drives its rotation. The telescopic unit and the second motor are wirelessly connected to the control module.

[0043] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0044] This application discloses an intelligent rat detection AI system for power distribution rooms.

[0045] Reference Figures 1-7 The intelligent rodent detection system for power distribution rooms includes a control module 1 and an infrared sensing module, a vision module 3, and an alarm module 4 connected to the control module 1. These functional modules work together to build an AI visual protection network, which can at least detect rodents entering the power distribution room in a timely manner. Early detection and early resolution can greatly reduce the safety hazards of existing rodent-proof boards and reduce economic losses.

[0046] The following is a detailed explanation:

[0047] The infrared sensing module includes several infrared sensors 2, with at least one sensor 2's detection probe facing the lower end of the door frame at the entrance of the power distribution room. Detecting the lower end of the door frame is more in line with the habits of mice, making it easier to detect mice passing by. The vision module 3 includes several cameras, with at least one camera's shooting end facing the detection area of ​​the infrared sensor 2. This allows the camera's recording to be reviewed after the infrared sensor 2 detects a suspected live animal such as a mouse. The camera is preferably a model with night vision functionality. The control module 1 can consist of a host computer in the power distribution room or other locations, connected to a control cabinet. It is connected to the infrared sensors 2 and cameras via a data acquisition card and cables, and also wirelessly connected to a remote management platform based on a cloud platform for convenient remote monitoring by staff. The control module 1 is configured as follows:

[0048] If the detection signal fed back by infrared sensor 2 indicates that a living target has passed by, then the video data of the camera at the current time point is extracted to generate a biological invasion video clip; wherein, the video clip can be about 3 minutes before and after receiving the detection signal.

[0049] Identification of invasive organisms is performed based on video clips of biological invasions. The identification of invasive organisms can be based on image recognition technology, which is an existing technology and will not be described in detail here. In this embodiment, at least the following feature can be identified: rat.

[0050] If the pre-selected target organism appears in the identification results, the alarm module 4 will activate the alarm and instruct the remote management platform to send a warning message to the pre-registered staff. The target organism refers to a rodent or other creature requiring protection. The remote management platform can send the warning message to the mobile phone number of a staff member pre-registered on the platform, or to a relevant app pre-downloaded to the staff member's mobile phone. The warning message may include: time, specific location, and a link to a video clip.

[0051] The above setup ensures that, on the one hand, the use of existing rodent barriers is not affected; on the other hand, it compensates for the shortcomings caused by the lack of rodent barriers at the entrances and exits of the power distribution room or the low height of the installed rodent barriers.

[0052] Once a rat enters the power distribution room, it will first be detected by the infrared sensor 2. After the detection is triggered, the control module 1 will call the entrance and exit image data at the corresponding time for verification. After the verification is passed, the system will notify the relevant personnel via SMS or other means so that the staff can eliminate the rat infestation in time and reduce economic losses.

[0053] In one embodiment of this application, considering that rats may enter the power distribution room from other locations besides personnel entrances and exits, the above oversight exists; at the same time, in order to improve the utilization rate of the equipment in the system, the following settings are made:

[0054] Reference Figure 1 and Figure 2 This application also includes a mobile support mechanism 5, which includes a track 51 installed around the inner wall of the power distribution room and a mobile trolley 52 slidably connected to the track 51. The track 51 can be installed in the wall through pre-embedded parts and is installed at a low position on the wall to monitor whether rats are passing by. A bracket 53 is hinged on the mobile trolley 52. ​​The bracket 53 is installed on the upper surface of the mobile trolley 52, and the hinge rotation surface of the bracket 53 is perpendicular to the wall. The infrared sensor 2 is ball-hinged to the end of the bracket 53, so that the infrared sensor 2 can adjust its angle when it moves to the side of the entrance door frame and point the detection range towards the lower end of the door frame.

[0055] The mobile trolley 52 is equipped with a drive unit 54 for moving the mobile trolley 52 along the track 51. The drive unit 54 is wirelessly connected to the control module 1. The drive unit 54 can be a servo motor. The servo motor is connected to the control module 1 via a wireless communication unit, such as an RF module, installed on the trolley. The wireless connection described below is similar. Another camera is located outside the power distribution room, with its camera end facing the path leading into the power distribution room, to facilitate observation of whether anyone needs to enter the power distribution room. The control module 1 is configured as follows:

[0056] The camera outside the power distribution room is defined as the A1 camera unit;

[0057] Behavior recognition is performed on the video data from the A1 camera unit, mainly to identify whether someone is walking towards the power distribution room. Behavior recognition is an existing technology and will not be described in detail here.

[0058] If the current time falls within the preset opening period of the power distribution room door, or if a person is detected walking towards the power distribution room, the control drive unit 54 drives the mobile trolley 52 to move to the entrance / exit door frame of the power distribution room (a pre-selected position on the side). The opening period of the power distribution room door is pre-entered by the staff based on their work time supervising and inspecting the power distribution room. When the power distribution room door is open or a person is about to walk towards the power distribution room, it means that the power distribution room door is about to be opened. When the door opens, the mobile trolley 52 and its infrared sensor 2 need to be moved to the side of the door to detect whether rats are taking the opportunity to sneak in.

[0059] It is understandable that the above process also includes the following information: the mobile vehicle 52 is not near the door at other times besides the specified time period. This is because this application sets it to perform patrol procedures at other times to detect rats entering the room from other locations besides the power distribution room entrance and exit. Specifically:

[0060] The camera located in the power distribution room is defined as a B1 camera;

[0061] If the video data from camera B1 indicates that the entrance / exit of the power distribution room is closed, the control drive unit 54 drives the mobile trolley 52 to perform an inspection process. This inspection process includes at least driving the mobile trolley 52 along a pre-set path and at a pre-set speed, while the infrared sensor 2 continuously detects. To facilitate data analysis and differentiation, cameras starting with "A" can be located outside the power distribution room, while cameras starting with "B" can be located inside. Multiple cameras inside the power distribution room can all start with "B," with camera B1 being the camera used to monitor the entrance / exit of the power distribution room.

[0062] Based on the above setup, this system can not only monitor the entrances and exits of the power distribution room and promptly detect rats entering the room, but also continuously detect other areas of the power distribution room during the closed-door phase to promptly detect rats entering the room from other locations, reducing oversights and improving the effectiveness of rat control. At the same time, because it can identify and analyze door-opening behavior and promptly return to its position near the door frame, its original monitoring effect on entrances and exits is not affected. Also, because the infrared sensor 2 is on the mobile cart 52, there is no need to deploy too many sensors indoors.

[0063] An ultrasonic sensor 6, rotating synchronously, is positioned to the side of the infrared sensor 2. The ultrasonic sensor 6 can be embedded in the bracket 53, with its detection end facing downwards when the bracket 53 is vertical (e.g., the lower end of electrical equipment or the side of a wall near the ground). The ultrasonic sensor 6 can also be wirelessly connected to the control module 1 via a wireless communication unit on the trolley. The control module 1 is electrically connected to several current sensors 7, each used to detect the current parameters of various electrical devices in the power distribution room. Example:

[0064] A separate current sensor 7 is fitted onto the outside of the wires of each electrical device;

[0065] Alternatively, if the power distribution room facilities have the required current detection function, then control module 1 connects to the power distribution platform of the power distribution room and directly calls the relevant current parameters.

[0066] Control module 1 is configured as follows:

[0067] Record the ID of each current sensor 7 and the location of the corresponding electrical equipment, and obtain the current parameters; the ID of the current sensor 7 can be the serial number that comes with it from the factory or a number that is preset by the staff, etc.

[0068] If the detection signal fed back by infrared sensor 2 indicates that a live target has passed by, the current parameter corresponding to the current position of the mobile car 52 is called. The live target includes, but is not limited to, mice. The current parameter is called for reference to analyze whether the infrared sensor 2 may misjudge due to excessive heat generated by the electrical equipment caused by excessive current parameter.

[0069] To obtain the current position of the mobile trolley 52, the track 51 can be divided into multiple segments. Upon receiving a detection signal from the infrared sensor 2 indicating the passage of a living target, the current parameters of the electrical equipment associated with the current track segment of the mobile trolley 52 can be retrieved. For example: each track segment is equipped with a corresponding proximity switch. By obtaining the position of the most recently triggered proximity switch, the approximate position of the mobile trolley 52 can be determined. The operator pre-records the current parameters of the electrical equipment within the detection range corresponding to each track segment, establishing a one-to-one correspondence, and stores this information in a database for easy retrieval of the current parameters using the current position of the mobile trolley 52.

[0070] If the current parameters meet the preset activation conditions of the ultrasonic sensor 6, the mobile trolley 52 is controlled to stop, and the signal fed back by the ultrasonic sensor 6 is obtained. Based on the signal fed back by the ultrasonic sensor 6, it is determined whether a target-type living body has passed by.

[0071] The activation condition for ultrasonic sensor 6 can be a preset current parameter. If the current parameter is greater than this parameter, ultrasonic sensor 6 is activated. The preset current threshold is the critical value at which the heating of electrical equipment causes infrared misjudgment. This value can be calculated by the operator or obtained through repeated experiments. Activating ultrasonic sensor 6 can reduce the possibility of misjudgment when the temperature generated during the operation of electrical equipment may interfere with infrared sensor 2.

[0072] If (based on the results of ultrasonic detection) a living organism of the target type passes by, the video data from the camera at the current time point is captured to generate a biological invasion video clip.

[0073] Based on the above settings, an ultrasonic sensor 6 is installed. This sensor can verify whether a live target is passing by when the electrical equipment may interfere with the infrared sensor 2 due to its own high temperature. After verification, video data is captured for biometric identification, which effectively prevents the subsequent process from being accidentally started due to misjudgment by the infrared sensor 2.

[0074] In another embodiment of this application:

[0075] It also includes a temperature sensor 8, which is located indoors and electrically connected to the control module 1. The control module 1 is configured as follows:

[0076] The system obtains the current indoor temperature and searches for a preset table of room temperature and current parameters to update the activation conditions of the ultrasonic sensor 6. The table of room temperature and current parameters can be obtained by staff through calculation or experiments at different room temperatures. When the ambient temperature exceeds a preset threshold (e.g., 40°C), even a lower current parameter may generate more heat, requiring the ultrasonic sensor 6 to be activated.

[0077] The high indoor temperature may cause even a small current parameter to generate a high temperature, which may interfere with the detection of infrared sensor 2. Therefore, in high-temperature environments (such as summer), the standard value of the current parameter can be reduced to improve the accuracy of detection, reduce the false judgment rate, and reduce the chance of false triggering of subsequent programs.

[0078] In one embodiment of this application, considering that if a conventional track trolley is used, the trolley needs to make a 90° turn around the wall of the power distribution room, and the trolley cannot change the direction of its wheels, then the track 51 needs to have a long buffer arc section at the corner, which affects the layout inside the power distribution room; and even if the wheels can adjust their orientation 360°, it is difficult to ensure that the trolley always faces the center of the room on one side. This affects the following: when the bracket 53 is near the door frame, it can rotate downwards to a horizontal position with a certain angle to facilitate the rotation of the infrared sensor 2 on it to face the lower end of the entrance and exit. However, in normal times, the bracket 53 needs to be retracted to prevent collisions during the movement of the trolley; therefore, this application also makes the following settings:

[0079] Reference Figure 2 , Figure 3 and Figure 4 The track 51 has a horizontal T-shaped cross-section, with the horizontal section connected to the wall (i.e., a horizontal T-shape), the tail end connected to the wall, and the other end extending to the side. The mobile trolley 52 is equipped with multiple rollers 521, the circular cross-sections of which are parallel to the side walls of the mobile trolley 52. ​​Rollers 521 mounted on each side wall form a group. The drive unit 54 includes multiple units, and its output shaft is fixed to the central shaft of at least one roller 521 in each group. When the drive unit 54 operates, it drives the connected roller 521 to rotate, and also drives the remaining rollers 521 in the same group to rotate. The outer wall of the roller 521 abuts against the track 51, thereby driving the mobile trolley 52 to move along the track 51.

[0080] The track 51 has multiple openings near the corners of the wall for the rollers 521 to pass through. For example, the track 51 can be rectangular when viewed from above. Openings are located at the four inner corners of the rectangle (i.e., the positions where the trolley 52 is about to turn), allowing the trolley 52 to continue moving and allowing another set of rollers 521 adjacent to the currently active roller 521 to pass through. That is, the trolley 52 is moved by switching to the set of rollers 521 corresponding to the other side wall and the drive unit 54. Each drive unit 54 can be wirelessly connected to the control module 1 via a communication unit on the trolley. The control module 1 precisely controls the activation or deactivation of a specific drive unit 54 based on the position of the trolley 52. ​​Because the track 51 has openings, an anti-fall mechanism 55 is provided to prevent the trolley 52 from falling off the openings.

[0081] Example of movement control for the mobile car 52:

[0082] A proximity switch is embedded at both ends of each side of track 51, and the proximity switches are wirelessly connected to control module 1. Control module 1 is configured as follows:

[0083] Define the four sides of the track 51 (which is rectangular when viewed from above) as sides A, B, C, and D. Define the multiple sets of rollers 521 of the mobile trolley 52 and their corresponding drive units 54 as sets E, F, G, and J, respectively, and match and bind them one by one with the four sides of the track 51, and store them in a preset database. Through this step, it is determined which set of rollers 521 needs to be used to drive the mobile trolley 52 to a certain side.

[0084] Record the proximity switch IDs corresponding to each side of track 51 and their matched track 51 segments, and store them in a preset database. For example, if the proximity switch IDs are D1, D2, etc., and D1 and D2 are embedded at both ends of side A, then they are bound to side A. Since the proximity switches are located at the beginning and end of each segment of track 51, one proximity switch may be paired with two track 51 segments. Subsequently, based on the moving direction of the moving trolley 52 (which is known by the order in which multiple proximity switches are triggered; for example, if the proximity switches are triggered in descending order of ID, then it is determined that the moving trolley 52 is about to move to the track 51 segment on the side of the proximity switch facing another proximity switch with a smaller ID), analyze which track 51 segment it is about to move to.

[0085] If any proximity switch is triggered, the system analyzes the track segment 51 to which the device will move next, searches the database based on the analyzed track segment 51, retrieves the corresponding roller group 521, controls the corresponding drive unit 54 to perform drive work based on the roller group 521, and controls the currently activated drive unit 54 to stop working.

[0086] The above settings not only meet the movement needs of the mobile trolley 52, but also ensure that the mobile trolley 52 always faces the center of the room on one side to cooperate with the bracket 53 and infrared sensor 2. They also ensure that the track 51 does not need to make a large section of protruding arc-shaped guide structure at the corner, thus achieving better performance.

[0087] Reference Figure 3 , Figure 4 and Figure 5 The anti-fall mechanism 55 includes a limiting block 551 and a traction rope 552. The track 51 has a limiting groove, which is located in the vertical section of the track 51 and is excavated along the thickness direction of the track 51. The limiting block 551 is slidably connected in the limiting groove. The section of the limiting groove near the corner of the wall can be rounded to facilitate the limiting block 551 turning along the rounded arc of the limiting groove.

[0088] The limiting block 551 is circular when viewed from above, and the outer wall of the limiting block 551 has protrusions. The limiting groove has a groove that fits the protrusion. The groove is opened on the groove wall of the limiting groove and along the width direction of the track 51. This setting can lock the limiting block 551 in the limiting groove to prevent the limiting block 551 from falling out. The ends of the traction rope 552 are respectively connected to the moving trolley 52 and the limiting block 551.

[0089] With the above configuration, the traction rope 552 connects the moving trolley 52 and the limiting block 551. The moving trolley 52 can drag the limiting block 551 to slide. At the same time, since the limiting block 551 is located in the groove and has a protrusion and a groove in the limiting slot to assist in limiting, it can pull the moving trolley 52, reducing the possibility of the moving trolley 52 falling off the opening of the track 51 and overturning.

[0090] Multiple position detection units 9, which detect the direction of the trolley falling into the groove, are installed inside the track. Each position detection unit 9 can be a proximity switch, embedded in the track. The approximate current position of the moving trolley can be obtained through the position detection unit 9. The position detection unit 9 can also be wirelessly connected to the control module 1 via a communication unit on the trolley. The control module 1 is configured as follows:

[0091] Record the position of each detection unit 9, the track 51 behind it, the detection range corresponding to each track 51, and the number of cameras matched to each detection range. Establish a one-to-one correspondence and store it in a pre-established database.

[0092] If the detection signal fed back by infrared sensor 2 indicates that a living target has passed by, the position of the location detection unit 9 of the most recent feedback signal is obtained, the database is searched to obtain its corresponding orbit segment 51 and detection range, and several cameras matched with it are obtained according to the detection range. The video data of several cameras matched at the current time node is extracted to generate a biological invasion video clip.

[0093] With the above settings, when the mobile trolley 52 patrols the power distribution room, the approximate position of the mobile trolley 52 can be determined through the position detection unit 9. If the infrared sensor 2 detects a live target passing by, the position of the mobile trolley 52 can be roughly determined through the position of the position detection unit 9. Furthermore, based on the position and number of the position detection unit 9, the corresponding video data of the detection terminal can be retrieved from the database in a timely manner, making the response to the detection of a live target more rapid and accurate.

[0094] In one embodiment of this application, considering the equipment layout characteristics of the power distribution room, the posture of the bracket 53 near the door frame and in other positions needs to be adjusted; otherwise, interference may occur to indoor electrical equipment during the movement of the trolley. Therefore, the following settings are provided:

[0095] Reference Figure 6 and Figure 7 The upper surface of the mobile trolley 52 is provided with a rotating component 56. The rotating component 56 includes a motor 561, a rope winder 562, and a pull rope, which are wirelessly connected to the motor 561. The motor 561 is installed on the upper surface of the mobile trolley 52 and is equipped with a corresponding reducer. The output shaft of the motor 561 is fixed to the center of the rope winder 562 through a coupling. The end of the rope winder 562 is circular and is rotatably connected to the upper surface of the mobile trolley 52. ​​The rope winder 562 may be provided with a corresponding support. The support and the trolley body are connected by bolts and nuts, and the rope winder 562 is rotatably connected to the support.

[0096] The rotation direction of the rope reel 562 is the same as that of the bracket 53. The pull rope (not shown in the figure) is wound around the rope reel 562 and its end is connected to the bracket 53 (such as the pull rope being tied and fixed to the bracket 53). The rope reel 562 can be driven by the motor 561 to reel in or out the pull rope, thereby driving the bracket 53 to rotate out or retract. A baffle 563 is provided on the side of the bracket 53 facing the wall to prevent excessive angular pulling when retracting the bracket 53. If the pull rope is over-retracted, the bracket 53 will abut against the baffle 563 and will not be able to continue rotating towards the wall. The baffle 563 is also provided with a ring to guide the direction of the pull rope. The pull rope passes through the ring and the pre-set hole in the bracket 53 and is tied to the bracket 53.

[0097] With the above settings, the bracket 53 can be rotated out and retracted through the cooperation of motor 561 and rope reel 562. Motor 561 is controlled by control module 1. For example, if the control drive unit 54 sends an instruction to move the mobile trolley 52 to the entrance / exit door frame of the power distribution room, then motor 561 drives rope reel 562 to release the rope, causing the bracket 53 to rotate out towards the side away from the wall. If the control drive unit 54 sends the mobile trolley 52 to perform an inspection process, then motor 561 drives rope reel 562 to retract the rope, causing the bracket 53 to retract towards the wall, until the bracket 53 is in a vertical position. This avoids the trolley occupying too much horizontal space and causing collisions or affecting the layout of indoor electrical equipment during movement. In another embodiment of this application, considering that if the position of infrared sensor 2 is fixed under the above settings, it is difficult to simultaneously and comprehensively detect near the door frame and other locations, infrared sensor 2 is configured to be adaptively adjustable. Specifically:

[0098] Reference Figure 6 The bracket 53 is equipped with an angle adjustment component 57, which is used to drive the infrared sensor 2, which is ball-hinged on the bracket 53, to adjust the angle of its detection end. The angle adjustment component 57 includes a connecting frame, a ball 572 rotating within the connecting frame, a rotating wheel 576 for pushing the ball 572 to rotate, and multiple balls 573 for assisting the rotation of the ball 572. The lower half of the ball 572 is a solid structure, and the upper half is a hollow structure. With this configuration, the ball 572 can always maintain the solid structure facing down. The infrared sensor 2 is installed in the hollow structure of the ball 572, with its detection end facing downwards. With the above configuration and in conjunction with the structural design of the ball 572, no matter how the connecting frame or the bracket 53 rotates, the detection end of the infrared sensor 2 can always face downwards.

[0099] The connecting frame includes multiple arc-shaped pocket plates 571, which are circumferentially distributed around the center of the sphere 572. The pocket plates 571 and the sphere 572 do not directly contact each other. There is a gap between the pocket plates 571 and the sphere 572 for the installation of the ball bearing 573. The outer wall of the ball bearing 573 abuts against both the pocket plate 571 and the sphere 572. The pocket plate 571 may be provided with a circular groove for the ball bearing 573 to abut and roll.

[0100] A telescopic unit 574 is provided at the end of the bracket 53 near the ball 572. The telescopic unit 574 can be a miniature electric cylinder, etc. The rotating wheel 576 is fixed to the telescopic end of the telescopic unit 574. The telescopic unit 574 pushes the rotating wheel 576 so that its outer wall abuts against the ball 572. The outer wall of the rotating wheel 576 is made of rubber to facilitate the rotation of the ball 572. The rotating wheel 576 is connected to a second motor 575 that drives its rotation. This can be a bracket 571 or a mounting frame for the second motor 575 extending from the end of the bracket 53. The second motor 575 is mounted on the mounting frame. Since the telescopic unit 574 can push the rotating wheel 576 out, in order to prevent the second motor 575 from being affected when the rotating wheel 576 is pushed out, the support legs of the mounting frame for the second motor 575 should be designed as telescopic structures to extend and retract synchronously with the rotating wheel 576.

[0101] Among them, motor 575 can be a geared motor, whose output end is fixed to the center of rotating wheel 576 through a coupling. When rotating wheel 576 is pushed to abut against ball 572 by telescopic unit 574, the angle of the detection end of infrared sensor 2 installed on ball 572 can be adjusted by rotating rotating wheel 576, thereby deflecting the angle of the detection end to the lower end of the door frame.

[0102] The telescopic unit 574 and motor 575 are wirelessly connected to the control module 1. A relevant control example is as follows:

[0103] Control module 1 is configured as follows:

[0104] If the control drive unit 54 receives an instruction to drive the mobile trolley 52 to move to the entrance door frame of the power distribution room, the control telescopic unit 574 will push the rotating wheel 576 to work, and the control motor 575 will drive the rotating wheel 576 to rotate.

[0105] The rotation angle of the ball 572 driven by the rotating wheel 576 is preset by the staff and can be obtained through repeated experiments. For example, if the ball rotates 30 degrees and happens to be facing the door frame, the control motor 575 drives the rotating wheel 576 to make the ball 572 rotate 30 degrees.

[0106] With the above settings, when the mobile trolley 52 moves to the side of the door frame of the power distribution room, the angle adjustment component 57 can be used to fine-tune the orientation of the detection end of the infrared sensor 2 so that it is aligned with the door frame and the entrance / exit area, making the detection range more accurate and thus improving the prevention of rats from entering.

[0107] How to use:

[0108] A rodent barrier is installed at the entrance and exit of the power distribution room. At the same time, the opening schedule of the power distribution room door is entered into the control module 1. At the corresponding time, the mobile trolley 52 is controlled to move to the side of the door, and the telescopic unit 574 and motor 575 are controlled to adjust the angle of the detection end of the infrared sensor 2. When the door is closed, the mobile trolley 52 is controlled to perform the patrol process (i.e., moving along the track 51 while the infrared sensor 2 performs detection). If a live target is detected passing by, the video from the corresponding camera is captured for biometric identification, and a text message or APP notification is sent to the staff.

[0109] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
