Detailed Description
The technical solution in the embodiments of the present invention will be described in further detail in the following clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
As shown in fig. 1, a heavy truck environment monitoring and blind area detection warning system, including environment monitoring early warning host computer 1 and with environment monitoring early warning host computer 1 electric connection's surveillance camera device 2, infrared light filling device 7 and radar 6, surveillance camera device 2 is equipped with saddle surveillance camera head and packing box surveillance camera head, wherein saddle surveillance camera head is used for realizing saddle control and traction locomotive monitoring of backing a car, packing box surveillance camera head associated cargo container door signal, when the cargo container door is opened, packing box surveillance camera head carries out video recording.
The utility model discloses an environmental monitoring early warning main control system 1 sends out node 8 through whole car gateway or other vehicle condition information and gathers the speed of a motor vehicle, turns to and the gear signal, according to different vehicle conditions, switches multiple field of vision reinforcing interface. Displaying 360 panoramic pictures to observe the surrounding conditions of the vehicle in a conventional scene; when the vehicle starts, the vehicle speed is more than 10km/h (can be set), a driving enhancement picture is displayed, a panoramic picture around the vehicle head is highlighted, and 360 panoramic views are displayed in a split screen manner; when the reversing gear of the vehicle is activated, a reversing enhancement picture is displayed, pictures around the tail of the vehicle are highlighted, and 360 panoramic views are displayed in a split screen mode; when the vehicle steering signal is activated, a steering enhancement picture is displayed, the picture at the side of the vehicle is highlighted, and 360 panoramic views are displayed in a split screen mode.
The saddle surveillance camera arranges and realizes the saddle and watch on in the driver's cabin back top, and the camera condition of carrying on of backing a car on the trailer is detected to environment monitoring early warning control host computer 1, when not going up the trailer, monitors the camera signal with the saddle and regards as the signal output display that backs a car, but automatic switch-over when backing a car realizes the observation of backing a car of traction locomotive. The environment monitoring and early warning control host 1 collects a container door signal, automatically stores pictures of each camera including container monitoring when a container door is opened, is designed to be powered by a storage battery B +, and can still work after a vehicle key power supply is powered off; the environment monitoring early warning control host 1 has dormancy awakening logic, and when the environment monitoring early warning control host is not awakened by other signals such as a cargo box door and the like, the environment monitoring early warning control host cannot be electrified and operated, and the static power consumption of the whole vehicle is not increased.
The infrared light supplementing device 7 is integrated with a photosensitive element, can detect ambient light conditions, and converts light signals into electric signals to be output to the environment monitoring and early warning control host 1. When the ambient light intensity is lower than 0.1Lux, the environment monitoring and early warning control host 1 senses the change of the electric signal, all the infrared light supplementing devices in the driving system are lightened, and the monitoring camera is internally provided with the optical filter to receive infrared light, so that all-weather 360-around-the-clock video monitoring is realized.
