Abstract

The utility model relates to a monitoring recorder for moving vehicles, belonging to a device which is used for measuring, displaying and storing the time, date, speed and mileage of the running of a vehicle. The utility model is composed of a display screen LCD, a central microprocessor IC-[1], a pulse synthesizer, a pulse generator, a buzzing alarm and an operation board which is three selecting push buttons, a display lighting switch and two canned pump device rivets. The electric signals of a speed magnetic sensor are compared, magnified and synthesized and sent into the central microprocessor, and the speed and mileage and time, date and display thereof are stored in case of future invocation, which provides reliable references for analyzing the reasons of vehicle accidents and monitoring the running state of the vehicle.

Description

Monitoring recorder for moving vehicle

The utility model running car monitor belongs to the instrument that time, date, speed and mileage to running car are measured and write down.

Measurement and record to motoring condition in prior art only limit to the speed of a motor vehicle and total kilometrage, and its shortcoming is not have corresponding time, date memory function.This is to analyzing the car accedent reason, and the monitoring motoring condition has increased difficulty.

The purpose of the utility model running car detection record instrument is that to be to design a kind of collection time, date, speed, travelled distance, sound and light alarm and data-storing be the one recording instrument, be the monitoring motoring condition, analyze the car accedent reason great convenience is provided.

The utility model running car monitor takes following scheme to realize, behind the vehicle starting, the flexible axle of automobile kilometer is just along with the gear in the gear case rotates together, on mileometer soft shaft, connect a magnetic force induction device, the mechanical rotation of mileometer soft shaft changes speed of a motor vehicle electric signal into by the magnetic force induction device, the standard frequency impulse singla that speed of a motor vehicle electric signal and impulse deviser produce is through comparing, amplify, after synthetic, be input to central microprocessor, microprocessor is according to pre-designed program work, with the time of automotive operation, date, data such as speed and mileage send LCD display to show, and according to giving the program of putting, drive alarm equipment alarm where necessary, simultaneously optionally the time of automotive operation, date, the corresponding storage of parameter such as speed and mileage is got up, desired data is by regulating the corresponding button in case of necessity, access from memory cell, and on LCD display, show.

The utility model running car monitor will be further described in conjunction with the accompanying drawings.

Fig. 1 is the circuit diagram of the utility model running car monitor.

Fig. 2 is the structural representation of the utility model running car monitor.

With reference to Fig. 1, Fig. 2, it is by behind the vehicle starting for the utility model monitoring recorder for moving vehicle, the flexible axle of automobile mileometer is along with the gear of gear-box rotates together, at mileometer soft shaft upper joint one magnetic force induction device (L), then the mechanical rotation of mileage flexible axle is transformed into the integration slice IC that speed of a motor vehicle electric signal is sent into pulse synthesizer (1) by magnetic force induction device (L)₃In, simultaneously, by the integration slice IC of impulse generator (2)₂Standard frequency pulse signal of 13 pin output; Speed of a motor vehicle electric signal and this standard frequency pulse signal are after comparing, amplify, synthesizing, by IC ₃6 pin output, be input to central microprocessor IC ₁17 pin on. Central microprocessor IC₁Be the encapsulation of 80 pin, 46 pin connect positive source, and 11 pin connect power cathode, 17 pin input vehicle speed pulse signal, 18 pin input conditioning signal, 18 pin and 28,29,30 pin consist of demonstration to be regulated, 44 pin are zero clearing, meet buzzer siren B between 47,48 pin and between 49,50 pin₁、B ₂, consisting of buzzing and report to the police (3), 1 to 7 pin and 51 to 80 pin connect LCD display, to show various performance datas. The vehicle speed pulse signal is input to central little processing IC by 17 pin₁After, microprocessor send LCD display to show the data such as time, date, speed and mileage of automobilism, and according to giving the program of putting, drives where necessary alarm B both by pre-designed program work₁、B ₂Report to the police, also the corresponding storage of above-mentioned relevant data is got up simultaneously, desired data can be by regulating button N in case of necessity₁、N ₂And N₃, from memory cell, access, and show at LCD display. LCD LCDs (4), the top shows the speed of motor vehicle, the below shows " year, month, day " and " time, minute, second ", three selection keys (5) are set on the operation panel and are the rivet (7) of display screen light switch (6) with two these instruments of sealing, 1. button controls the top display screen, it is selective that the fourth gear level is set, and 1. when level " 1 ", display screen shows instantaneous velocity to button; When level " 2 ", show 15 speed in last 30 seconds; When level " 3 ", show the maximum speed in nearest 72 hours; When level " 4 ", show from enabling this instrument to begin so far the tired note of mileage numeral. 2. button controls the below display screen, shows " year, month, day " corresponding with above-mentioned function and " time, minute, second ", and the two alternately appears on the display screen. 3. button is spare key, just enables when increasing other record entry designs. The shell of the utility model monitoring recorder for moving vehicle and operation panel adopt polytetrafluoroethylene (PTFE) to make, and have waterproof, shockproof, anti-flaming, firm characteristics, after shell is bonding the sealing mark are arranged, and generally can't open.

The power supply of the utility model monitoring recorder for moving vehicle uses the capacitor batteries of the power supply of automobile own and deposit, in establish automatic charging device, even when the automobile power-off, still can use, ensured the normal operation of instrument. Also be provided with stable-pressure device in the circuit, during such as voltage rising or electric current increasing, the normal operation of stable-pressure device protection instrument.

The effect of the utility model monitoring recorder for moving vehicle is simple in structure, and the LCD numeral shows time, date, speed and the mileage of automobilism; Record also shows 15 the interior speed of front 30 seconds of stopping, and on average shows a speed in per 2 seconds; Record stops F-Zero and corresponding time thereof in front 72 hours, this be recorded in automobile out of service after, can keep 7 days longer time. If automobile continues operation, then front 72 hours record material is cancelled in turn, and recorder works on; Record is enabled the mileage that this monitoring and recording instrument begins from automobile; Show automobilism residing " year, month, day " and " time, minute, second ", and get up with above speed, the corresponding storage of mileage, prepare against and call; Can at any time call relevant data after the parking, and show successively; After the outage, still can preserve above data.

The embodiment of the utility model running car monitor, it is by read-out LCD and central microprocessor IC ₁Constitute with buzzing warning (3) with pulse synthesizer (1) and impulse deviser (2), the speed of LCD LCDs top display machines motor-car, the below shows " year, month, day " and " time, minute, second ", and three selection keys (5) and read-out lighting switch (6) and two rivets (7) formations of sealing these instruments are set on the operating panel.
