Description

A video-integrated emergency broadcasting system Technical Field

[0001] This invention relates to the field of emergency broadcasting technology, and in particular to a video-integrated emergency broadcasting system. Background Technology

[0002] The immense pain and threats that sudden accidents bring to people's lives and property force us to deeply consider emergency response methods to minimize damage during such incidents. Broadcasting, with its advantages of simple construction, convenient installation, long transmission distance, wide coverage, and high transmission speed, has played a crucial role in numerous past emergency warnings, command, evacuations, and resettlement efforts—a role that cannot be replaced by any other means or method. Its advantages are even more pronounced when disasters cause traffic disruptions, power outages, and communication failures.

[0003] Existing emergency broadcast systems require high placement, typically on poles, to ensure effective information dissemination. This necessitates personnel climbing for disassembly and maintenance, which is inconvenient. To ensure personnel can monitor the broadcast area, cameras for video recording can be installed. This paper proposes a video-broadcast integrated emergency broadcast system. Firstly, the height of the mounting bracket is adjustable, facilitating disassembly and maintenance. Secondly, a protective structure protects the equipment during heavy rain and typhoons. Thirdly, the camera's shooting angle is adjustable, enabling personnel to monitor the accident area via video. Summary of the Invention

[0004] This invention provides a video-broadcast integrated emergency broadcast system, which solves the problems mentioned in the background art above. It facilitates the inspection, disassembly and assembly of emergency broadcast systems, and can protect equipment in extreme weather. In the event of a sudden accident, staff can promptly send emergency notices and emergency commands via broadcast.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A video-integrated emergency broadcast system includes a load-bearing base, a support chassis, a broadcast speaker column, a monitoring box, a broadcast control box, a monitoring camera, and a monitoring base. A load-bearing column is fixedly connected to the top of the load-bearing base. The load-bearing column has an adjustment groove. A brake stepper motor is fixedly installed on the inner wall of the adjustment groove. A ball screw is fixedly connected to the brake stepper motor. A screw nut is threaded onto the outer wall of the ball screw. Connecting rods are fixedly connected to both sides of the screw nut. The connecting rods on both sides are fixedly connected to the support chassis. The broadcast speaker column, monitoring box, and broadcast control box are installed on the top of the support chassis. A support rod is fixedly connected to the top of the support chassis. A load-bearing plate is fixedly connected to the top of the support rod. The monitoring base is installed on the top of the load-bearing plate. A steering wheel is rotatably connected to the top of the monitoring base. A connecting frame is fixedly installed on the top of the steering wheel. The inner wall of the connecting frame is rotatably connected to the monitoring camera. A protective cover is fixedly connected to the top of the load-bearing column.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, each side of the load-bearing column has a corresponding slotted hole for the connecting rod. The connecting rods on both sides pass through the slotted holes and are fixedly connected to the support base, so that the screw nut can drive the support base to move up and down in contact with the load-bearing column through the connecting rod.

[0008] Furthermore, the load-bearing plate is fixedly connected to a limiting cylinder, the inner diameter of which is adapted to the load-bearing column, and the load-bearing column is slidably connected to the limiting cylinder, so that the load-bearing plate can fit the load-bearing column and move up and down stably.

[0009] Furthermore, there are two monitoring bases, which are respectively installed at the top ends of the load-bearing plate, and the monitoring cameras on the two monitoring bases can perform video monitoring of the surroundings.

[0010] Furthermore, there are two broadcast speakers, which are respectively installed on the top two sides of the support chassis, and the two broadcast speakers can broadcast from both sides of the support chassis.

[0011] Furthermore, the protective cover is made of tempered glass, and the equipment can be placed inside the protective cover for safety protection, while the monitoring camera can continuously monitor the outside world.

[0012] Furthermore, the support chassis has through holes adapted to the load-bearing columns, and the inner wall of the through holes is slidably connected to the load-bearing columns, so that the support chassis can stably fit the load-bearing columns when rising and falling.

[0013] Furthermore, a No. 1 steering motor is fixedly installed on the inner wall of the monitoring base. The No. 1 steering motor is fixedly connected to the steering wheel, and the No. 1 steering motor can stably drive the steering wheel to rotate on the top of the monitoring base.

[0014] Furthermore, a second steering motor is fixedly connected to the connecting frame, and the drive end of the second steering motor is fixedly connected to the monitoring camera. The second steering motor can drive the monitoring camera to rotate on the inner wall of the connecting frame.

[0015] The beneficial effects of this invention are as follows: This invention provides a video-integrated emergency broadcasting system, which has the following advantages:

[0016] 1. The load-bearing column is installed on the ground through the load-bearing base. When the brake is started, the stepper motor rotates the ball screw, which drives the screw nut to rise and fall in the adjustment groove. The screw nut can drive the support base to rise and fall against the load-bearing column through the connecting rod. When disassembly and maintenance are required, the support base can be lowered to facilitate the disassembly and maintenance of the broadcast column, monitoring box, broadcast control box, and monitoring camera. After maintenance or installation is completed, the support base can be raised so that the broadcast column can be used for emergency broadcasting at a high position.

[0017] 2. The surveillance camera can perform video monitoring from a high position. In case of extreme weather and after the broadcast speaker and surveillance camera have been used, the support base can be raised until the top is close to the protective cover, so that the broadcast speaker, monitoring box, broadcast control box and surveillance camera can be placed inside the protective cover for safety protection.

[0018] 3. Starting the No. 1 steering motor and turning the steering wheel can drive the monitoring camera to adjust its lateral angle. Starting the No. 2 steering motor can drive the monitoring camera to rotate on the inner wall of the connecting frame, so that the longitudinal angle of the monitoring camera can be adjusted, and the monitoring range of the monitoring camera can be adjusted as needed.

[0019] 4. This type of video-integrated emergency broadcast facilitates the inspection, disassembly, and installation of emergency broadcast equipment, and can protect the equipment in extreme weather. In the event of an emergency, staff can promptly send emergency warnings and commands via broadcast and monitor the broadcast area via cameras.
