Abstract
The utility model discloses a motorcycle overspeed alarm which comprises a speed sensor, an A/D (analog to digital) converter, a single-chip microcomputer, a speaker, an LED display and an alarm lamp. The speed sensor is connected with an input end of the single-chip microcomputer through the A/D converter. An output end of the single-chip microcomputer is connected with the speaker through a power amplifying circuit. The output end of the single-chip microcomputer is further connected with the LED display and the alarm lamp. The single-chip microcomputer is an MCS-8051 single-chip microcomputer. The input end of the single-chip microcomputer is further connected with a keyboard. The motorcycle overspeed alarm is simple in structure, reliable in operation, low in cost and completely suitable for motorcycles of different types.
Description
Technical field
The utility model belongs to motor bike driving safety field, relates to a kind of motor bike overspeed alarm.
Background technology
Motor bike is cheap, and manoevreability is good and adapt to various road surfaces, is a kind of important vehicle in rural area, China city.But the less stable of motor bike is particularly worked as motor bike and is under the state of driving over the speed limit, and its stability reduces greatly with safety, in case be in an emergency, tends to cause the major traffic accidents of car crash to take place.Therefore designing a kind of simple motor bike overspeed alarm device extremely is necessary.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, a kind of motor bike overspeed alarm is provided.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of motor bike overspeed alarm, comprise speed sensor, A/D converter, micro controller system, loud speaker, light-emitting diode display and alarm lamp, wherein, speed sensor links to each other with the input end of micro controller system by A/D converter, the mouth of micro controller system is connected with loud speaker by power amplification circuit, and the mouth of micro controller system also is connected with light-emitting diode display and alarm lamp.
The utility model also has following technical characterictic:
Described micro controller system adopts the MCS-8051 micro controller system, and the input end of micro controller system also is connected with keyboard.
The utility model is simple in structure, reliable operation, with low cost, is suitable for the motor bike of various models fully.
Description of drawings
Fig. 1 is an annexation scheme drawing of the present utility model.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of motor bike overspeed alarm, comprise speed sensor, A/D converter, micro controller system, loud speaker, light-emitting diode display and alarm lamp, wherein, speed sensor links to each other with the input end of micro controller system by A/D converter, and the mouth of micro controller system is connected with loud speaker by power amplification circuit, and the mouth of micro controller system is connected to light-emitting diode display and alarm lamp between also.
Described micro controller system adopts the MCS-8051 micro controller system, and the input end of micro controller system also is connected with keyboard.MCS-8051 micro controller system anti-interference resistance is good, is applicable to the occasion of harsh environment.The frequency of operation of the CPU of MCS-8051 micro controller system adopts 6MHz, makes things convenient for system that the count pulse of speed sensor is carried out the fast speed processing.Various external devices such as the MCS-8051 micro controller system can connected storage, telltale, speed sensor.The MCS-8051 micro controller system has the characteristics of low-power consumption and low voltage operating pattern, can utilize battery that system is powered.
Described speed sensor adopts Hall element.Speed sensor is the rapid wear device in the vehicle sensors, so adopted noncontacting proximity sensor, mainly is made up of Hall switch, magnet.Its principle of work is the appropriate location that Hall switch and magnet is installed in motorcycle front-wheel vehicle frame and wheel respectively, and during motorcycle driving, under the effect of magnet, Hall switch can produce on-off signal.
Described power amplification circuit is the power amplification circuit of this area routine; Light-emitting diode display also is conventional light-emitting diode display.
Behind the utility model electrification reset, the voltage signal that car speed sensor detects is by in the A/D converter conversion back input micro controller system, and micro controller system at first extracts the default value of the retention parameter of the inner Flash memory device of micro controller system as the motor bike the max speed.Utilize regularly 100ms of timer then, extract the in-to-in pulse count value, calculate the motor bike actual vehicle speed, micro controller system is presented at current vehicle speed on the light-emitting diode display by the control light-emitting diode display, and micro controller system compares the maximum speed value of the speed of a motor vehicle and setting simultaneously.If the speed of a motor vehicle is less than or equal to the maximum speed value of setting, alarm lamp and loud speaker are not worked, otherwise alarm lamp and loud speaker are started working the deceleration of prompting motorcycle driver.If the user resets maximum speed by keyboard, micro controller system can store new setting value in the Flash memory device and forever preserve, up to next update.
