[0001] This utility model relates to the field of campus monitoring technology, specifically to an interactive campus monitoring device based on digital twin technology. Background Technology
[0002] Digital twins fully utilize data from physical models, sensors, and operational history to integrate multi-disciplinary, multi-physical, multi-scale, and multi-probabilistic simulation processes, mapping these data in virtual space to reflect the entire lifecycle of the corresponding physical equipment. Digital twins are a concept that transcends reality, and can be viewed as a digital mapping system of one or more important, interdependent equipment systems. Digital twin technology is also commonly used in daily campus monitoring; some existing surveillance equipment is installed on campus walls to monitor security in real time.
[0003] However, these monitoring devices cannot transmit voice information, and students at the monitoring locations cannot transmit voice messages to the monitoring backend. There is still considerable room for improvement in the functionality of the monitoring devices. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a campus interactive monitoring device based on digital twin technology to solve the problems mentioned in the background technology.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

A connecting block is provided at the rear position of the lower surface of the top plate, and two rotating blocks are symmetrically arranged on the upper surface of the camera. The connecting block is located between the two rotating blocks, and the connecting block and the rotating blocks are rotatably connected by a screw.
[0007] The camera is located below the top panel, with the camera lens tilted downwards, and a speaker is installed on the lower surface of the top panel near the front.
[0008] The microphone has multiple voice holes on the upper front, a spring switch in the middle of the lower front, and mounting blocks symmetrically arranged on both sides.
[0009] A power module is also provided on the lower surface of the top plate, and a power signal line is provided on the back of the microphone. The end of the power signal line away from the microphone is connected to the power module.
[0010] Preferably, the top plate has through holes symmetrically arranged around its upper surface, and the four corners of the top plate are rounded.
[0011] Preferably, the power signal line is fixed to the wall of the campus by a retaining ring, and multiple retaining rings are evenly attached to the power signal line at equal intervals.
[0012] Preferably, a nut is provided at one end of the screw, and a washer is provided at the contact position between the nut and the rotating block.
[0013] Preferably, a reinforcing rib is provided between the side of the connecting block and the lower surface of the top plate.
[0014] Preferably, a pin hole penetrating the mounting block is provided at the middle position of the mounting block.
[0015] Preferably, both the loudspeaker and the microphone are connected to the campus monitoring center.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The top plate is attached to the top of the corridor of the school teaching building. Bolts are used to fix the top plate through the through holes. The microphone is attached to the wall of the corridor. Bolts are used to pass through the mounting block and then fix it to the wall. This fixes the entire device.
[0018] The connecting block is rotatably connected between two rotating blocks via a screw, so that the camera is rotatably installed on the lower surface of the top plate. The camera can capture the scene of the teaching building corridor in real time. The speaker is connected to the school's monitoring center via a signal line.

[0019] The microphone is connected to the school's monitoring center via a signal line. A spring switch is installed on the microphone's signal transmission circuit. When the spring switch is pressed and a student speaks into the voice hole, the sound can be transmitted to the monitoring center. When an unexpected situation occurs in the teaching corridor and a student needs help, they can press the spring switch and speak into the voice hole to communicate with the staff and teachers at the monitoring center immediately.
[0020] After the spring switch is released, the sound cannot be transmitted to the monitoring center at the back through the voice hole, which can prevent the normal teaching noise in the corridor from being transmitted to the monitoring center at the back.
[0021] With cameras monitoring normally, the system can transmit warnings and alerts from the monitoring center to the corridor and students' calls for help to the monitoring center via speakers and microphones, thus improving interactivity. Attached Figure Description
