Description

Technical Field

[0001] The utility model relates to the technical field of driving recorders, in particular to a driving recorder system with a vehicle-mounted multi-channel control switch. Background Art

[0002] Drive recorder is an instrument that records relevant information such as images and sounds while a vehicle is traveling. After installing the drive recorder, video images and sounds of the entire driving process can be recorded, which can provide evidence for determining traffic accident liability.

[0003] After searching, the patent with application number CN202222492903.9 discloses a driving recorder system with a vehicle-mounted multi-way control switch, including a first input device, a driving recorder main board and a multi-way control switch main board. The first input device obtains the start signal or the close signal triggered by the user and sends it to the driving recorder main board. The driving recorder main board sends the start signal or the close signal to the multi-way control switch main board. The multi-way control switch main board controls the on-off of the control switch thereon according to the start signal or the close signal. The control switch is connected to the vehicle-mounted device, so as to control the operation of the vehicle-mounted device. The driving recorder system of this application, on the basis of the original driving recorder, adds a multi-way control switch main board. The multi-way control switch main board integrates multiple control switches for controlling the operation of the vehicle-mounted device, so that the user can centrally control each vehicle-mounted device through the driving recorder, realizes convenient control of the vehicle-mounted device, and improves driving safety.

[0004] The above scheme lacks processing of the data collected by the camera. Unprocessed audio signals and image signals will have more external interference, resulting in blurred converted sound and video. The large amount of data collected by the camera will take up more storage space and affect data transmission efficiency. In addition, since the installation position of the driving recorder is generally high, located on the upper part of the windshield, it is inconvenient to control various vehicle-mounted devices by operating the multiple control switches on the driving recorder. Therefore, we need to propose a driving recorder system with a vehicle-mounted multi-way control switch. Utility Model Content
