Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a school bus remote safety monitoring device. Background Technique

[0002] A camera (CAMERA or WEBCAM), also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, real-time monitoring, etc. Ordinary people can also communicate with each other through the camera over the network with images and sounds. In addition, people can also use it for various current popular digital imaging and audio-visual processing;

[0003] In order to improve the safety index of students, monitoring devices are often installed on school buses to perform face recognition scans when students get on and off the bus, so as to record the process of students getting on and off the bus. However, the existing monitoring devices are generally fixedly installed, so that they cannot accurately identify students of different heights during face recognition scans. As a result, students need to change their heights, leading to low recognition efficiency and inconvenience in use. Therefore, we propose a school bus remote safety monitoring device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a school bus remote safety monitoring device.

[0005] To solve the problem that the existing monitoring devices are generally fixedly installed, so that they cannot accurately identify students of different heights during face recognition scans. As a result, students need to change their heights, leading to low recognition efficiency and inconvenience in use, the utility model provides the following technical solution: A school bus remote safety monitoring device, including a protective housing, a camera is provided on the surface of the protective housing, both side surfaces of the protective housing are fixedly connected with support rods. The two support rods can make the protective housing more balanced, thus avoiding the inclination of the protective housing and improving the stability of shooting and recognition. The top of each of the two support rods is slidably sleeved with a fixed rod, a fixing plate is fixedly connected between the two fixed rods, a threaded hole is opened at the top of the fixing plate, and the threaded hole can facilitate the installation and fixation of the fixing plate, thereby facilitating the installation and fixation of the entire device and improving the practicability of the entire device. A chute is opened at the bottom of the fixed rod, the support rod is slidably inserted into the chute, a connecting rod is fixedly connected to the surface of the support rod, the other end of the connecting rod is fixedly connected with a limiting block, and a limiting groove is further opened on the side surface of the chute inside the fixed rod cavity. The limiting block is slidably inserted into the limiting groove. The setting of the limiting block and the limiting groove can make the connecting rod more stable, and thus make the support rod more stable.

[0006] As a further solution of the present utility model: A sliding rod is fixedly connected to the side surface of the support rod. The other end of the sliding rod is located outside the support rod. The sliding rod can conveniently drive the support rod to slide, and it is convenient for the staff to operate on the outside of the support rod.

[0007] As a further solution of the present utility model: A limiting rod is longitudinally and fixedly inserted into the inner cavity of the limiting groove. A through hole is opened at the top of the limiting block. The limiting block is slidably sleeved on the limiting rod through the through hole. The limiting rod can make the limiting block more stable when sliding, thereby preventing the limiting block from tilting when sliding up and down, and further improving the stability of the support rod.

[0008] As a further solution of the present utility model: A spring is sleeved on the circumferential surface of the limiting rod. One end of the spring is fixedly connected to the top of the inner cavity of the limiting groove, and the other end of the spring is fixedly connected to the top of the limiting block. The spring can exert a downward rebounding effect on the limiting block, so that the limiting block is always located at the bottom of the inner cavity of the limiting groove without external force.

[0009] As a further solution of the present utility model: Two connecting rods are fixedly connected to each support rod. The two connecting rods are respectively fixedly connected to the front and back surfaces of the support rod, and the two support rods are symmetrically arranged. The two connecting rods can make the support rod more stable when sliding.

[0010] As a further solution of the present utility model: A strip-shaped groove is opened on the outer side surface of the fixed rod. The sliding rod is located outside the fixed rod through the strip-shaped groove. The strip-shaped groove can facilitate the sliding of the sliding rod, so that the sliding range of the sliding rod is larger, and thus it can be used by students with a large height difference.

[0011] As a further solution of the present utility model: A concave hole is opened on the side surface of the support rod. A bolt is inserted into the concave hole. The support rod is fixedly installed on the side surface of the protective shell through the bolt, and two bolts are provided on each support rod. The two bolts can make the support rod more stable on the protective shell, thereby improving the stability of the whole device.

[0012] As a further solution of the present utility model: The top view shape of the support rod is a square, and the top view shape of the sliding groove is also a square, and the side length of the square in the top view of the sliding groove is greater than the side length of the square in the top view of the support rod. This can facilitate the sliding of the support rod in the sliding groove and prevent the support rod from rotating.

[0013] Adopting the above technical solutions, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the threaded rod is inserted into the threaded hole to adjust the angle of the camera, and then the fixing plate is fixedly installed on the school bus through the threaded rod. When a shorter student needs face recognition, the student faces the face towards the camera, and the boarding and alighting records of the student can be made. When a taller student needs face recognition, the teacher slides two sliding rods upward with both hands, and the sliding rods will drive the support rod to slide upward in the sliding groove. When the support rod slides upward, it will drive the connecting rod to slide upward, and the connecting rod will drive the limiting block to slide upward in the limiting groove. When the limiting block slides upward, it will slide upward along the limiting rod, and when the limiting block slides upward, it will compress the spring. When the camera slides to be parallel to the face of the student, the sliding rods can be stopped, and then the face of the student can be recognized and recorded. After the recording is completed, the sliding rods are released, and the spring will rebound downward to limit the block, and the limiting block will drive the connecting rod to slide downward, the connecting rod will drive the support rod to slide downward, the support rod will drive the protective housing to slide downward, and the protective housing will drive the camera to return to the initial state, which is convenient for face recognition of the next student. It can conveniently adjust the height of the monitoring device, thereby achieving the effect of accurately recognizing students, improving the recognition efficiency, being convenient for teachers to use, and being able to perform face recognition on students with a large height difference.
