Abstract

The utility model relates to an alcohol detector based on a commercial vehicle unit and a CAN bus device, which comprises a vehicle unit host (1), an LCD display touch screen (2), an alcohol detector (3), a CAN bus control module (5) and an AWS pre-warming system (6), wherein the vehicle unit host (1) is connected with the LCD display touch screen (2) through a data port and a control port; the vehicle unit host (1) is connected with the CAN bus control module (5) through an SPI interface; the CAN bus control module (5) is connected with the alcohol detector (3) through an input port; and the CAN bus control module (5) is connected with an AWS pre-warning system (6) through a CAN bus. The utility model can realize LCD display, touch screen operation, alcohol monitoring in a driver cab and the work of the AWS pre-warning system, so as to remind a driver in an intelligent and humanized way before a car runs and suffers from accidents, and effectively prevent traffic accidents.

Description

A kind of alcohol detection and CAN bus unit based on the commercial vehicle carrier unit

(1), technical field the utility model relates to a kind of alcohol detection and CAN bus unit based on board units, particularly a kind of isolated plant of expanding with the matching used alcohol detection of ARS commercial vehicle carrier unit, the realization of AWS early warning system, liquid crystal touch screen display operation and CAN bus.

(2), background technology is along with the development of China's economic technology, various large-scale haulage vehicles, especially passenger-cargo commercial haulage vehicle is increasing rapidly.And the security performance in passenger-cargo commercial transport vehicle use more and more is subject to people's attention, it also is the emphasis that the automaker emphasizes recent years always, many manufacturers have all carried out a large amount of researchs that continue to vehicle active safety and passive safety in recent years, to reach safe maximization.The passenger-cargo commercial vehicle of present operation lacks a kind of based on commercial vehicle carrier unit alcohol detection and CAN bus system design system, can't be before motor-vehicle accident, and intelligent, hommization ground is pointed out the driver, thereby can't effectively be stoped the generation of traffic hazard.

(3), utility model content technical problem to be solved in the utility model is, providing is a kind of alcohol detection and CAN bus unit based on the commercial vehicle carrier unit, be used to realize the realization of liquid crystal display, touch screen operation, the interior alcohol monitoring of pilothouse and AWS early warning system, and then before can be implemented in running car, before the accident, the prompting driver of intelligent, hommization, thus the generation of traffic hazard effectively stoped.

The technical measures that the utility model is taked are:

A kind of alcohol detection and CAN bus unit based on the commercial vehicle carrier unit comprise the board units main frame, it is characterized in that: also comprise the liquid crystal display touch-screen, alcohol monitoring, CAN bus control module and AWS early warning system; The board units main frame is connected with the liquid crystal display touch-screen with control port by FPDP; The board units main frame is connected with the CAN bus control module by the SPI interface; The CAN bus control module is connected with the alcohol monitoring by input port; The CAN bus control module is connected with the AWS early warning system by the CAN bus.

Good effect of the present utility model is: by using this commercial vehicle carrier unit alcohol detection and CAN bus system design system, can realize alcohol monitoring and the work of AWS early warning system in liquid crystal display, touch screen operation, the pilothouse, and then can be implemented in before the running car and accident before, the driver is pointed out on intelligent, hommization ground, thereby effectively stops the generation of traffic hazard.

(5), embodiment further specifies the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, this example comprises board units main frame 1, and described board units main frame 1 comprises ARM9S3C2440 unit and Flash storage unit.Also comprise liquid crystal display touch-screen 2, alcohol monitoring (being the alcohol monitoring modular) 3, CAN bus control module 5 and AWS early warning system 6; Board units main frame 1 is connected with liquid crystal display touch-screen 2 with control port by FPDP; Board units main frame 1 is connected with CAN bus control module 5 by the SPI interface; CAN bus control module 5 is connected with alcohol monitoring 3 by input port; CAN bus control module 5 is connected with AWS early warning system 6 by the CAN bus.

The utility model can detect alcohol concentration in the pilothouse, realizes liquid crystal display, touch screen operation, the work of AWS early warning system.The terminal user can realize man machine operation interface and AWS early warning work by liquid crystal display and touch-screen.

Described AWS early warning system 6 can be carried out early warning for the person for driving a car provides danger such as front truck collision, route deviation, back car knock into the back.

Described alcohol monitoring 3 detects alcohol concentration in the pilothouse, makes data are provided thereby carry out judgement such as alcohol excess for system.

Described CAN bus control module 5 is alcohol monitoring 3, AWS early warning system 6 and other CAN bus interface equipment I/O control maincenter.

Described power module 4 is the total system power supply, and board units main frame 1 is used for system after the voltage after the direct current transformation of automobile storage battery carries out step-down once more.

Described liquid crystal display touch-screen 2 provides the interface of hommizations such as demonstration, operation for system.

Described board units main frame 1 is responsible for driving demonstration and operation communication with liquid crystal display touch-screen 2; Carry out communication with AWS early warning system 6, to early warning information handle, show, prompting etc.; Alcohol monitoring 3 data that obtain are judged demonstration, prompting etc.; Carry out communication with control center, information is submitted to control center.
