Abstract
The utility model relates to a safety monitoring device for a motor vehicle in driving. The utility model discloses an intelligent dynamic monitoring instrument for the motor vehicle for the sake of obtaining the accurate monitoring information of the driving motor vehicle. The safety monitoring device comprises a speed sensor, a record box and a display; the utility model is characterized in that the speed sensor is a photoelectric speed sensor, and the transmission shaft is provided with a blanking disc, and the circle of the blanking disc is provided with a plurality of line troughs. Two pairs of photoelectric couplers are arranged inside and outside the line troughs of the blanking disc, making the output pulse signals judge the march or the countermarch of the vehicle. The transmission shaft is provided with two oil-contained shaft sheaths that guarantee the normal operation of the transmission shaft at a high speed. Since the blanking disc transmits the increasing pulses to the record box under the cooperation of photoelectric couplers, the sampling time interval is shortened to less than 0.1 second, and the accuracy of the measuring speed and the distance is improved, thereby fully recording each detail about the doubtful points of the accident before the vehicle stops and providing the effective data for the analysis of the accident.
Description
Technical field
The utility model relates to the safety monitoring assembly of power actuated vehicle motoring condition.
Background technology
Power actuated vehicle dynamic security monitoring device is of a great variety on the market, with regard to its structure, generally all is made up of speed sensor, recording box, telltale.And speed sensor adopts the magnetic inductive film structure usually, and the magnetic inductive film volume of this hall device is bigger, can only adorn 6-8 magnetic inductive film around the sensor transmission shaft, and transmission shaft rotates a circle and can only produce 8-12 impulse singla.Because producing the pulse count of output is restricted, influenced the number of times of single chip microcomputer counting in the recording box, thereby seriously influenced sampling rate and accurately measured, caused the prior art ubiquity following problem: the one, oversize to the sampling time interval of the various status informations of vehicle, general about 0.5 second, the data that do not have vehicle running state in this time gap can't be analyzed the accident condensation point.The 2nd, can not discern vehicle and advance or retreat, judge to traffic accident and bring difficulty.The 3rd, accurately measuring speed and distance.
Summary of the invention
For obtaining under the power actuated vehicle motoring condition monitoring information accurately, the utility model provides a kind of self-propelled vehicle Intelligent Dynamic monitor.It can reflect the state in the power actuated vehicle driving process effectively, is convenient to accurately judge and analyze traffic accident, support vehicles safety traffic.
The utility model is to realize by following technical scheme, it is by speed sensor, recording box, telltale is formed, one end of speed sensor links to each other with vehicle gear box, another signal end links to each other with recording box, the recording box mouth links to each other with telltale, speed sensor comprises upper shell, lower house, transmission shaft, printed board, its structural feature is that speed sensor is a light electricity velocity sensor, on transmission shaft, be provided with a blanking disc, the circumference of dish is provided with many wire casings, in the blanking disc wire casing, the outside is provided with two pairs of photoelectrical couplers, the pin of photoelectrical coupler is connected with printed board, is positioned on the transmission shaft at blanking disc two ends respectively to be provided with an iolite bushing.
The number of many wire casings can be equal to or greater than 32 on the above-mentioned blanking disc.
The utility model is according to photovoltaic principals, and two pairs of photoelectrical couplers are located at the medial and lateral of blanking disc wire casing, comprises velocity information and direction information simultaneously in the impulse singla that photoelectrical coupler is exported.When transmission shaft rotated, blanking disc whenever rotated a circle, two pairs of impulse singlas that each output of photoelectrical coupler equates with wire casing bar number, and also the phase place of two pulse signals has front and back.The pulse signals outside if a pulse signals of inboard lags behind when vehicle advances, one pulse signals in the outside inboard pulse signals that will lag behind when vehicle rollback so, discerning also like this in recording box fully, registration of vehicle advances or retreats.Increase because blanking disc under the cooperation of photoelectrical coupler, outputs to the pulse count of recording box, thereby the number of times of per second sampling is increased greatly, the time gap of sampling shortens, and the accuracy rate of measuring speed and distance has improved.
The utility model is owing to adopted blanking disc and photoelectrical coupler, and sampling time interval is better than 0.1 second, has improved measuring accuracy.Because fully each details of accident doubtful point before the registration of vehicle stagnation of movement provides abundant active data to the analysis accident, for transportation industry provides actv. law enforcement instrument.Adopted iolite bushing, guaranteed that transmission shaft can the high speed normal operation.
Description of drawings
Embodiment below with reference to accompanying drawing is further described the utility model.
Fig. 1 is the structural representation of the utility model light electricity velocity sensor.
The specific embodiment
Among Fig. 1, the upper shell 1 of light electricity velocity sensor and lower house 2, transmission shaft 3 are equipped with blanking disc 6 on it, have 32 wire casings on the circumference of present embodiment blanking disc.Two pairs of photoelectrical couplers 7 are contained in the medial and lateral of blanking disc wire casing, and the pin of photoelectrical coupler is connected with cable 9 by printed board 8, and cable links to each other with recording box.Iolite bushing 4 respectively is housed on the transmission shaft at blanking disc two ends, is used for supporting shaft, and make the transmission shaft can be under high-speed operation owing to the friction heating produces stuck phenomenon.Nut 5 joins with vehicle gear box.When monitor is worked, the transmission shaft rotation of the light electricity velocity sensor that links to each other with motor vehicle gearbox owing to have 32 wire casings on the blanking disc, whenever rotates a circle, two photoelectrical couplers are respectively exported 32 impulse singlas, and signal is input to again to be handled in the recording box and the storage desired data.
