Portable hypervelocity alarm device based on the prevention of highway second accident
Technical field
the utility model belongs to electronic technology field, is a kind of warning device.
Background technology
in recent years, along with Chinese economic development, the quantity of automobile is increasing; The automobile that has had the whole world 1.9%, however simultaneously, road traffic accident is soaring year by year especially; Traffic fatalities have accounted for global 15%; Population accident rate, car accident rate, interruption of service rate are the first in the world, are the highest countries of road safety accident, and situation is very severe.And in the processing of some accidents, owing to accident treatment being lacked experience, rescued reasons such as untimely, often occur " second accident ".
Mostly what " second accident " appearred in
is highway and city express passway; Reason is mostly these roads are totally enclosed one-way road; Speed of a motor vehicle design is higher, and the driver estimates deficiency usually to emergent obstacle or accident, when obstacle or accident entering sight line; It is too late to tend to brake, and this just causes second accident easily.
Summary of the invention
The technical matters that
the utility model will solve provides a kind of portable hypervelocity alarm device based on the prevention of highway second accident, and Rapid Alarm, field management, emergency relief, information acquisition and the issue of a cover traffic hazard, the scheduling of making a strategic decision etc. are a series of fast, the operating process of standard thereby can set up.
The scheme of
the utility model technical solution problem is to adopt main frame to become the portable hypervelocity alarm device based on the prevention of highway second accident with secondary mechanism; Main frame comprises main control module one, knotmeter, hypervelocity car plate acquisition module, sounding module one, light emitting module and wireless transmitter module; The serial ports B of main control module one connects knotmeter; The serial ports A of main control module one connects hypervelocity car plate acquisition module; The serial ports C of main control module one connects wireless transmitter module; The PA0-PA3 pin of main control module one connects the I/O mouth of light emitting module, and the PA4-PA7 pin of main control module one connects the I/O mouth of sounding module one, and secondary machine comprises main control module two, wireless receiving module and sounding module two; Main control module two links to each other with serial ports between the wireless receiving module, and the PA0 pin of main control module two connects the I/O mouth of sounding module two.During use main frame is placed on the roadside that vehicle sails 200~300 meters apart from the scene of the accident in direction into, secondary machine is carried by the policeman, when knotmeter has been measured car process and hypervelocity (> 60 kilometers/hour) time; Information is passed to main control module one; Main control module one through light emitting module flash, through the sounding module one warning over-speed vehicles of sounding, and send a warning message to the policeman of processing accident through wireless transmitter module simultaneously, after the wireless receiving module in the secondary machine is received information; Through main control module two control sounding modules two sounding, warning policeman.As the overspeed of vehicle (> that goes; 120 kilometers/hour) time, except that alarm, utilize the license plate image collecting unit to capture and the identification vehicle license plate simultaneously, so that as traffic police's later stage voucher of handling violating the regulations.
the utlity model has characteristics such as simple in structure, stable performance, volume be little; Be mainly used in highway police or the staff effective protection when on duty; Its development has been made useful exploration to the prevention of highway second accident, for highway traffic police and staff's life security escorts.Simultaneously license plate recognition technology has improved the intellectuality and the automatization level of traffic control also for the smart electronics policing system has played positive impetus, to the sustainable development and the construction of means of transportation tachnical storage is provided.
