For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0035] like Figure 1 As shown, the vehicle video, CAN and GPS integrated monitoring system provided by the present invention. The system includes a shell, the shell includes a main body 4, an upper cover plate 7, a front baffle 8 and a rear baffle 5; a video acquisition module, arranged in the shell, for collecting vehicle video and audio information; a CAN acquisition module, arranged in the shell, for collecting CAN data; and a 4G communication module, connected to the video acquisition module and the CAN acquisition module, for uploading the information collected by the video acquisition module and the CAN acquisition module to a cloud server; wherein the video acquisition module includes a video module mainboard 1 and a hard disk 6, and the CAN acquisition module includes a CAN module mainboard 2 and a 4G communication module 3; the video module mainboard 1 is fixed on the main body 4, and the CAN module mainboard 2, the 4G communication module 3 and the hard disk 6 are fixed on the upper cover plate 7.
