Abstract
The utility model discloses an inter-vehicle safe distance alarming device. The inter-vehicle safe distance alarming device comprises radar, a controller area network (CAN) transceiver, a single chip microcomputer, a displayer, a vehicle speed sensor and a voice alarming device, wherein the radar, the CAN transceiver, the single chip microcomputer and the displayer are sequentially connected, and the single chip microcomputer is respectively connected with the voice alarming device and the vehicle speed sensor further. By utilizing radar technology and single chip microcomputer technology, collected driving information is reported to a driver in time and helps the driver to make correct decisions, alarming signals are sent automatically in the moment of possible danger for reminding the driver to take measures, and therefore driving safety can be guaranteed. The inter-vehicle safe distance alarming device is simple in structure, convenient to install, high in sensitivity, and suitable for being widely applied to various motor vehicles.
Description
Technical field
The utility model belongs to intelligent transportation field, is specifically related to safety distance warning device between a kind of vehicle.
Background technology
Be accompanied by the quick growth of automobile quantity in the world wide, road crowded, the frequent generation of accident also becomes the problem that becomes increasingly conspicuous, and it is imperative develop the feasible intelligence warning of driving a vehicle.Warning device not only will guarantee the safety of vehicle, but also wants and can be accepted by the subjective feeling of chaufeur.Investigation shows that the ratio that the rear-end impact accident accounts for highway accident is the highest, the economic loss that causes and personal casualty maximum.Therefore need a kind of device that can effectively reduce rear-end collision urgently, effectively promote the safety of highway driving.
Summary of the invention
The purpose of this utility model is, safety distance warning device between a kind of vehicle is provided, and this device can help chaufeur to make correct decisions, in the moment that may cause danger, sends alarm message, reaches the purpose of driver assistance.
In order to realize above-mentioned task, the utility model is solved by the following technical solutions:
Safety distance warning device between a kind of vehicle, comprise radar, CAN transceiver, micro controller system, telltale, car speed sensor and phonetic alarm, wherein, radar, CAN transceiver, micro controller system are connected successively with telltale, and micro controller system also is connected respectively with car speed sensor with phonetic alarm.
The utility model also has following technical characterstic:
Described radar adopts CS R-28 radar.
Described CAN transceiver adopts the 82C250 transceiver.
Described micro controller system adopts the AT89C51 micro controller system.
Described car speed sensor adopts the JK08/NS43NCT1 sensor.
Described phonetic alarm adopts the ISD4002 annunciator.
The utility model utilizes Radar Technology and singlechip technology, and the driving information that collects is presented to chaufeur in time, helps it to make correct decisions, in the moment that may cause danger, can send alerting signal automatically, remind chaufeur to take measures, guarantee driving safety.This apparatus structure is simple, is convenient to installation and highly sensitive, and all kinds of self-propelled vehiclees suit to be widely used in.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, based on safety distance warning device between a kind of vehicle of technical solutions of the utility model, comprise radar, CAN transceiver, micro controller system, telltale, car speed sensor and phonetic alarm, wherein, radar, CAN transceiver, micro controller system are connected successively with telltale, and micro controller system also is connected respectively with car speed sensor with phonetic alarm.
In the utility model, radar adopts CS R-28 radar, is used for obtaining spacing information; The CAN transceiver adopts the 82C250 transceiver, as the interface of information transmission between radar and the micro controller system; Micro controller system adopts the AT89C51 micro controller system, for the treatment of the demonstration output of radar, vehicle speed signal and control information; Car speed sensor adopts the JK08/NS43NCT1 sensor, is used for obtaining this vehicle speed information; Phonetic alarm adopts the ISD4002 annunciator, is used for sending alerting signal; Telltale adopts the LED Liquid Crystal Display (LCD), is used for showing the speed of a motor vehicle, spacing and alarm message etc.
Working process of the present utility model: the range only radar that is installed in automotive front obtains distance and the relative velocity of Ben Che and front truck, passes to micro controller system through the CAN transceiver and handles.Micro controller system receives the radar signal that the transmission of CAN transceiver comes on the one hand, obtain the speed information of this car on the other hand by car speed sensor, then these speed and range information are calculated and judge: if spacing greater than the safe distance between vehicles of setting, telltale shows current vehicle speed and apart from the spacing of front truck; If spacing, then triggers annunciator less than safety distance and reports to the police, telltale shows dangerous the prompting simultaneously, makes chaufeur notice dangerous situation, in time takes measures.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
