Through installing this kind of device on the private car, can reduce the possibility that traffic accident takes place, reduce the injury to the people, be favorable to people's safety to drive to go on a journey, impel the construction in city intelligent transportation field.
Description
Technical field
It is a kind of vehicle intelligent suggestion device based on ultrasonic ranging and vehicle speed sensor that the utility model relates to, and belongs to intelligent transportation field.
Background technology
Industry and the development of transportation, the high concentration of urban population bring test to the ability of urban transportation.The population concentrated must bring concentrated vehicle, and being on the increase of vehicle must bring safety problem, and human safety issues is the problem that the mankind pay close attention to jointly.So a kind of vehicle intelligent suggestion device based on ultrasonic ranging and vehicle speed sensor, to personal safety, further developing of urban transportation is significant.
In urban transportation, human safety issues becomes the common problem that the Chinese whole society faces, but the human safety issues on traffic route, difficult and permanent, and be difficult to thorough solution, so how in the city that population gathers, the generation of effective minimizing traffic hazard, reducing the injury of traffic hazard on personal safety has affected into key.Even if developed country's industrialization, urbanization speed such as America and Europes, in the starting of municipal intelligent traffic management aspect comparatively early, but the human safety issues in traffic route still can thoroughly to solve.China's Traffic Development is rapid, traffic route meets an automobile accident often, jeopardizes personal safety.Before this, also do not have a kind of vehicle-mounted, the prompt system of robotization can contribute in this respect.Therefore, adopt modern advanced science and technology to reduce the generation of traffic hazard, significant.
Utility model content
The purpose of this utility model is to provide a kind of vehicle intelligent suggestion device based on ultrasonic ranging and vehicle speed sensor, effectively can reduce the generation of traffic hazard, reduces traffic hazard to the injury of personal safety, is particularly useful for highway.
The utility model comprises and being made up of control module, ultrasonic wave module, voice broadcast module, data processing module, power module and vehicle speed measurement module.
Described control module is the core of whole device, and adopt single-chip microcomputer to be responsible for the scheduling of whole device, connected is ultrasonic wave module, vehicle speed measurement module, voice module, data transmission module and power module.
Described ultrasonic wave module module is for measuring the speed of a motor vehicle, and concrete enclosed mass two ultrasonic sensors, for measuring the distance with front and back vehicle, ultrasonic sensor realizes sound, electricity conversion.This sensor can be launched ultrasound wave and receive ultrasonic echo, and converts corresponding electric signal to.Connected is controller module.
Described vehicle speed measurement module is used for the current speed of a motor vehicle of measuring vehicle, comprises a photo-electric vehicle speed sensor, and what be directly connected with it is control module.
Described voice module is directly connected with control module, for reporting current vehicle condition, comprises the current speed of a motor vehicle of vehicle and spacing etc.
Described data processing module, for calculating the current front-and-rear vehicle distance of vehicle and in conjunction with the speed of a motor vehicle, judges vehicle present case whether safety, and submits to control module, and determine whether voice broadcast by control module, what it directly connected is control module.
