[0040] The present application provides the following embodiments

[0041] Embodiment 1 ​

[0042] This invention provides an electric rodent-proof roller shutter baffle device for power distribution rooms, such as... Figures 1-7 As shown, it includes a U-shaped door frame panel 1, which is used to connect with a door frame. Two symmetrically arranged roller shutters 100 are rotatably connected inside the U-shaped door frame panel 1. A roller shutter 101 is slidably connected up and down inside the roller shutter 100. An infrared sensor is provided on the roller shutter 100. A controller is provided inside the U-shaped door frame panel 1. The controller is electrically connected to the roller shutter 100, the roller shutter 101, and the infrared sensor.

[0043] The U-shaped door frame panel 1 can be installed inside the door frame using bolt connections.

[0044] Preferably, a monitoring camera is installed on the gate (100).

[0045] The working principle and beneficial effects of the above technical solution are as follows: In the initial state, the sides of the two roller shutters 100 that are closest to each other are in contact, and the planes of the two roller shutters 100 are parallel to each other. Figure 1 In the coordinate system shown, the roller shutter 101 extends out of the roller shutter 100. When a person approaches the roller shutter 100, the infrared sensor is triggered. At this time, the controller controls the roller shutter 101 to move downward and retract into the roller shutter 100. Then, the controller controls the roller shutter 100 to rotate. The roller shutter 100 rotates from its plane parallel to the x-axis to its plane parallel to the y-axis. At this time, the two roller shutters 100 are parallel to each other, and a passage is left in the middle of the two, through which personnel can enter the power distribution room.

[0046] In this invention, the second roller shutter 101 is in an extended state during rodent blocking and in a retracted state during personnel entry and exit, perfectly meeting the rodent blocking requirements. Furthermore, this invention uses a two-roller shutter 100 rotating fan design instead of the traditional one-piece rodent barrier design. Combined with an infrared sensor, it can accurately sense personnel approach and automatically open the shutter, eliminating the safety hazard of personnel tripping over the rodent barrier. Additionally, when a large external force (such as the force of impact on the shutter during a trip) hits the first roller shutter 100, the first roller shutter 100 will be pushed open under the force, preventing personnel from tripping.

[0047] This invention utilizes surveillance cameras and image processing technology to automatically identify and count passing mice using a rodent recognition algorithm. The counting results are then input into a trained deep learning model, which ultimately generates a rodent extermination plan.

[0050] The working principle and beneficial effects of the above technical solution are as follows: when the infrared sensor senses that someone is approaching, the controller controls the first driving member to drive the linkage bent rod 1013 to rotate, so that the first shutter 100 rotates from a state of being parallel to the x-axis direction to a state of being parallel to the y-axis direction, at this time, the two first shutters 100 are parallel to each other, and a passage is left in the middle of the two first shutters 100, and personnel can enter the power distribution room through the passage. During the rotation process, the guide roller 1011 rolls along the T-shaped rolling groove 1010, the rolling direction is as shown in FIG. 10B, and the linkage elastic member 1014 is in a gradually shortened state.

At the same time, since the top protection plate 103 is basically the same height as the first shutter 100, both are relatively low, and the personnel with high height can step on the top protection plate 103 to enter the power distribution room, and the anti-skid strips 1030 can play an anti-skid role.

[0068] An angular velocity sensor is arranged on the roller shutter plate one 100 and used for detecting the angular velocity of each work of the roller shutter plate one 100;

[0069] A controller and an alarm are electrically connected with the pressure sensor, the timer, the angular velocity sensor and the alarm, the controller controls the alarm to alarm based on the pressure sensor, the timer and the angular velocity sensor, and comprises the following steps:

[0070] Step one: based on the pressure sensor, the timer and the angular velocity sensor, the actual alarm coefficient of the bristle replacement alarm system is calculated:

[0071]

[0072] Wherein, ε is the actual alarm coefficient of the bristle replacement alarm system, L is the length of the rigid bristles, ω i is the detection value of the angle sensor when the roller shutter plate one 100 rotates for the i-th time, t i is the detection value of the timer when the roller shutter plate one 100 rotates for the i-th time, γ is the material wear coefficient of the rigid bristles, F iα is the detection value of the pressure sensor when the roller shutter plate one 100 rotates for the i-th time, φ is the material tensile stiffness of the displacement compensation elastic member, S is the contact area between the rigid bristles and the U-shaped door frame plate 1, W is the preset wear work of the rigid bristles, e is a natural number, and the value is 2.72, n is the total number of rotations of the roller shutter plate one 100, ρ1 is the material density of the U-shaped door frame plate 1, and ρ2 is the material density of the rigid bristles;

[0073] Step two: the controller compares the actual alarm coefficient of the bristle replacement alarm system with the preset alarm coefficient of the bristle replacement alarm system, if the actual alarm coefficient of the bristle replacement alarm system is greater than the preset alarm coefficient of the bristle replacement alarm system, the alarm gives an alarm.
