Abstract

An engineering vehicle monitoring system comprises a pick-up head, a video converter, an i.MX53 processor and a display screen. The pick-up head is connected with the i.MX53 processor through the video converter. The i.MX53 processor is connected with the display screen. Video signals are acquired by using the pick-up head to shoot environment images when an engineering vehicle is working. The video converter converts the video signals into video data which are then sent to the i.MX53 processor. The i.MX53 processor then converts the video data into video images which can be identified by the display screen. The video images are further displayed on the display screen. The i.MX53 processor which enables a wide applicable temperature range can be adapted to adverse working environments of the engineering vehicle, for example, high-temperature environments and environments with great temperature differences between day and night. By acquiring and displaying the environment images of the engineering vehicle, the engineering vehicle monitoring system makes an operator no longer suffer a visual field blind area during the engineering vehicle working process. The working efficiency of the engineering vehicle is thus improved.
