Description
Technical field
The utility model relates to a kind of Electrical Bicycle warning, relates in particular to a kind of Electrical Bicycle follower's collision prevention warning.
Technical background
In recent years, Electrical Bicycle due to cheap, pollute the advantages such as little, easy-to-use, deeply be subjected to consumers in general's favor.But along with the universal use of Electrical Bicycle, relevant traffic accident happens occasionally; Wherein rear-end impact occupies suitable high range, has brought certain economic loss for bicyclist and family thereof, even causes life to threaten.Therefore, develop a kind of can Real-Time Monitoring and remind battery-driven car navigating mate battery-driven car and the place ahead obstacle (vehicle) between the system of distance be necessary.
Summary of the invention
In order to reduce and avoid the generation of Electrical Bicycle rear-end impact traffic accident, the purpose of this utility model is: propose a kind of Electrical Bicycle follower's collision prevention warning, this system can be in the distance between Ben Che and the place ahead obstacle less than safety distance the time, automatically send warning, remind the bicyclist in time to take measures, to ensure safety.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of Electrical Bicycle follower's collision prevention warning, comprise super sonic acceptor circuit, temperature sensor, micro controller system, loud speaker and ultrasonic transmit circuit, wherein, the mouth of super sonic acceptor circuit and temperature sensor is connected with micro controller system, and the mouth of micro controller system is connected with ultrasonic transmit circuit with loud speaker respectively.
The utility model also has following other technologies characteristics:
Described super sonic acceptor circuit adopts the CX20106A chip.
The model of described temperature sensor is SMT160-30.
Described micro controller system is the 89C51 micro controller system.
Described loud speaker is the audio-signal-driven loud speaker.
The security standpoint that the utility model travels from battery-driven car adopts ultrasonic measuring distance technology, has very high sensitivity and antijamming capability; Wherein the ambient temperature that provides of temperature sensor has improved the precision of range finding.This systematic economy, practicality and real-time, accuracy rate is high, has improved the safety of Electrical Bicycle navigating mate.
Description of drawings
Fig. 1 is structure connection diagram of the present utility model.
Fig. 2 is program flow diagram of the present utility model.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
The specific embodiment
Fig. 1 is structure connection diagram of the present utility model, comprise super sonic acceptor circuit, temperature sensor, micro controller system, loud speaker and ultrasonic transmit circuit, wherein, the super sonic acceptor circuit adopts the CX20106A chip, and its effect is that reception is sent by ultrasonic transmit circuit and runs into the super sonic that the place ahead obstacle reflects; The model of temperature sensor is SMT160-30, its effect be to provide current environmental temperature as micro controller system calculate battery-driven car and obstacle spacing from parameter T; The model of micro controller system is 89C51, and it act as between processing, Ben Che and the obstacle of ultrasonic signal and temperature signal apart from the computing of d and the triggering of crashproof signal alarm circuit etc.; Loud speaker is the audio-signal-driven loud speaker, and its effect is the reminding driver deceleration that gives the alarm less than safety distance the time when battery-driven car and leading vehicle distance; Ultrasonic transmit circuit is used for to battery-driven car the place ahead emission super sonic.
The utility model program circuit as shown in Figure 2.
Principle of work is as follows:
The P1.0 mouth of 89C51 micro controller system produces square-wave signal, sends the ultrasonic signal of same frequency after power gain by ultrasonic transmit circuit, and meanwhile the time meter in micro controller system begins timing.Ultrasonic signal runs into obstacle and reflexes to the super sonic acceptor circuit, obtain effective waveform after amplifying processing and shaping pulse, form interrupt signal, enter the INT0 mouth of micro controller system, make the INT0 mouth of micro controller system produce interruption, time meter stops timing, obtains super sonic from being transmitted into the time gap Δ t of reception.Known by the ultrasonic ranging principle, between Ben Che and obstacle apart from d be:
d=V*Δt/2 (1)
And hypracoustic propagation speed V is relevant with ambient temperature T, and the pass between them is:
V=331.45+0.61*T (2)
For calculate more exactly between Ben Che and obstacle apart from d, settle temperature sensor in the utility model, ambient temperature is measured in real time.When the numerical value of d surpasses the safety distance size of the utility model regulation, start the buzzing warning function, remind the bicyclist to note, so that it is in time handled it.
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.
