Monitoring personnel can send control instructions to the cloud deck through the remote monitoring management platform 60, so that the vehicle-mounted monitoring camera 10 is remotely controlled to collect and snapshot monitoring image pictures at different angles when audio and video interaction is carried out or under the condition of requirement.
The vehicle-mounted computer equipment 20 is also connected with a vehicle-mounted GPS device, and can receive vehicle positioning information in real time and provide positioning navigation service for the vehicle; and sends the vehicle positioning information to the remote monitoring management platform 60 along with the monitoring influence information, so that the remote monitoring management platform 60 displays the position of the vehicle on the electronic map, and the position of the operating vehicle is monitored conveniently.
The cloud server 50 (ECS) is a Service platform that provides comprehensive Service capability for various internet users, and integrates three core elements of internet application in the conventional sense: computing, storage, and networking, and can provide a user with a public internet infrastructure service. In this embodiment, the cloud server 50 is used as a cloud storage platform of the system, and actively issues an audio/video real-time transmission control message, the on-board computer device 20 sends the stored monitoring image information to the cloud server 50 through a wireless Wi-Fi network or a 4G/5G communication network after receiving the monitoring image information, and the cloud server 50 receives and stores the monitoring image information, so that the problem that monitoring influence information cannot be traced and checked due to damage and loss of the on-board computer device 20 is avoided, and meanwhile, the safety and reliability of the on-board monitoring data are ensured.
Meanwhile, the cloud server 50 can also transcode the monitoring image information, and provide support for online playing and downloading of the monitoring image on other various video service platforms; and the RTMP protocol can be simultaneously output, so that support is provided for live broadcast of various mobile devices.
The in-vehicle projection device 30 uses a hud (head Up display) head-Up display. The HUD is a short-term head-up display and is also called a parallel display system, and as a flight auxiliary instrument on an aircraft, a pilot can see important information required by the pilot without lowering the head, and along with the development of the HUD technology, the technology is also gradually applied to the automobile industry. The HUD head-up display carried by the automobile mainly has the function of projecting important driving information such as speed per hour, navigation and the like onto a windshield in front of a driver, so that the driver can see the important driving information such as speed per hour, navigation and the like without lowering head or turning head as much as possible.
On the basis, the HUD head-up display is connected with the vehicle-mounted computer equipment 20 through a data line, so that a monitoring image acquired by the vehicle-mounted monitoring camera 10 in real time is acquired from the vehicle-mounted computer equipment 20, and the monitoring image is projected onto the front windshield 41 of the vehicle independently or along with the speed per hour and navigation information, so that a driver can directly monitor the movement direction of a passenger in a back row through the image reflected by the front windshield 41 in real time in the driving process, the attention is not required to be dispersed, and the driving safety is guaranteed.
In this embodiment, the HUD head-up display may be implemented as a unitary device (host and transmitter together) or a separate device (host and transmitter not together). When the HUD head-up display adopts an all-in-one machine, the HUD head-up display can be directly and safely arranged on the center console 42; if the HUD head-up display adopts a split machine, the main machine part can be placed below the driver seat and fixed through screws. The emitter portion is attached to the console 42 so that it can project a monitor image toward the front windshield 41. No matter what HUD head-up display adopted is all-in-one or split machine, all need adjust the projection angle of transmitter according to the inclination of front windshield 41 for the projection area is in the field of vision scope when the driver sits straight.
In the present embodiment, a reflection film 44 is attached to the front windshield 41 of the vehicle in a region corresponding to the projection area of the HUD head-up display. Therefore, a larger and more effective reflection area is provided as a projection area of the HUD head-up display, so that technical support is provided for clearly displaying the monitoring image.
