Abstract
The utility model discloses an alarm device of abnormal speed attenuation of vehicle, wherein the power of device is from a vehicle power. The device comprises a speed sensor, a vehicle speed analyzer, and an alarm signal device, wherein the speed sensor is mounted on a speed-variable motion element of vehicle while the output electric signal is transmitted to a signal input of the speed analyzer via a signal line, the speed analyzer is composed of a single-chip computer and external elements while the signal output is electrically connected to the alarm signal device via a signal line. The utility model has better practicality and high reliability.
Description
Technical field
The utility model relates to the prior-warning device of the improper decay of a kind of motor vehicle speed.Belong to automotive field.
Background technology
At present, along with increasing of self-propelled vehicle, relevant traffic accident sharply increases, and causes huge economy and personal casualty loss to the country and people.In numerous traffic accidents, because the speed of a motor vehicle is too fast, the speed rapid attenuation that front truck takes emergency brake or other reason to cause, then the car chaufeur but has little time to take measures, and knocking into the back of causing therefrom waits the shared ratio of traffic accident also cooresponding greatly.Present existing self-propelled vehicle carries out glancing impact, no matter be slight braking or emergency braking, self-propelled vehicle in the back, its manifestation mode is that the stoplight stop lamp of front truck is bright, especially at a high speed or under the nearer situation of spacing, back car chaufeur can not judge in time that front truck is emergency braking or slight braking, and many situations are to realize that when back car chaufeur it is that the speed of a motor vehicle just takes urgent measure the generation that can't avoid traffic accident at this moment when extremely decaying that front truck is braked.So the information that existing self-propelled vehicle security set can not the improper quick decline of vehicle speed before the very first time, automobile driver provided has rearwards timely and effectively increased traffic accident generation probability such as self-propelled vehicle knocks into the back, shunts into one another greatly.
Summary of the invention
The purpose of this utility model is to provide the prior-warning device of a kind of safe and reliable, the easy to implement improper decay of motor vehicle speed.When the normal speed decay appearred in self-propelled vehicle, this device can in time send early warning signal.Vehicle reacts as early as possible behind the prompting tail, takes measures, thereby significantly reduces the generation of traffic accident.
The purpose of this utility model is achieved in that the prior-warning device of the improper decay of a kind of motor vehicle speed, and the power supply of device is taken from automobile power source, it is characterized in that: it is made up of speed sensor, motor vehicle speed analyser, early warning signal device respectively; Speed sensor is contained on the car speed varying motion parts, the electric signal of its output is sent to the signal input of motor vehicle speed analyser by signal transmssion line, the motor vehicle speed analyser is made up of one-chip computer and peripheral cell respectively, and the signal output of motor vehicle speed analyser is electrically connected by signal transmssion line and early warning signal device.
The utlity model has following advantage: the prior-warning device of the improper decay of a kind of motor vehicle speed, the power supply of device is taken from automobile power source, it is characterized in that: it is made up of speed sensor, motor vehicle speed analyser, early warning signal device respectively; Speed sensor is contained on the car speed varying motion parts, the electric signal of its output is sent to the signal input of motor vehicle speed analyser by signal transmssion line, the motor vehicle speed analyser is made up of one-chip computer and peripheral cell respectively, and the signal output of motor vehicle speed analyser is electrically connected by signal transmssion line and early warning signal device.
Description of drawings
Fig. 1 is the hardware logic block scheme of the prior-warning device of the improper decay of the utility model motor vehicle speed.
The specific embodiment
As shown in Figure 1, the prior-warning device of the improper decay of a kind of motor vehicle speed, the power supply of device is taken from automobile power source, it is characterized in that: it is made up of speed sensor 1, motor vehicle speed analyser 2, early warning signal device 3 respectively; Speed sensor 1 is contained on the car speed varying motion parts, the electric signal of its output is sent to the signal input of motor vehicle speed analyser 2 by signal transmssion line 4, motor vehicle speed analyser 2 is made up of one-chip computer and peripheral cell respectively, and the signal output of motor vehicle speed analyser 2 is electrically connected by signal transmssion line 5 and early warning signal device 3.Principle of work of the present utility model is such, speed sensor 1 is made up of photoelectric circuit and signal amplification circuit, car speed is detected, the electric signal of speed sensor 1 output is sent to the signal input of motor vehicle speed analyser 2 by signal transmssion line 4, motor vehicle speed analyser 2 carries out analyzing and processing by the one-chip computer job procedure to signal, when the very fast variation of car speed, when belonging to the normal speed variation, the signal output of motor vehicle speed analyser 2 passes through signal transmssion line 5 output signals to early warning signal device 3, early warning signal device 3 sends early warning signal, and this early warning signal is to differ from normal braking automobile wigwag or other electronics transmits.The utlity model has advantage easy for installation, safe in utilization.
