Abstract

The utility model provides a non-contact type radio frequency IC card recording device which can automatically record all kinds of vehicle status parameters in the running process. The device has the function of car 'black box'. A speed sensor, a brake sensor, a gun sensor and a brake pump oil pressure sensor which form sensor components are connected with a microcomputer I/O input port in parallel. The signals after A/D conversion treatment are transmitted to the microcomputer by sensors. The data (particular compressed brief-code of time and parameters) after the microcomputer processing is transmitted to an IC card reader and writer, and then is written into the IC card made by special material through radio frequency wireless induction. The data is also displayed on a state display. The other line signal is transmitted to a sound system after the analysis by the microcomputer to make automatic sound prompt. Once an accident happens, the signal of speed sensor will ensure the recorder to stop recording. And all the vehicle status datas before the accident will be kept in the IC card. The original parameters of the time can be got by using any same IC card reader to read the IC card, which provides reliable technology guarantee for the standardization, automatization and intelligentize of the scientific management of the ministry of communication.

Description

Vehicle safety travel intelligent monitoring and recording device

Technical field

The utility model relates to a kind of microelectronics technology, both non-contact type RF IC card read/write recording devices, particularly relate to a kind of not only can the time the real vehicle traveling process of record automatically in various vehicle condition parameters (speed of a motor vehicle, throttle, braking etc.), but also can be by computer automatic analysis processing relevant information and the monitoring in the logger, automatic speech prompting (as " brake system pressure has deficiency; please overhaul " etc.), liquid crystal display, handle traffic accident for traffic management system original objective data is provided, the vehicle condition security parameter is realized intelligent management and monitoring.

Background technology

Progress and development along with society, the recoverable amount of automobile is just with annual 15%～20% speed increment, traffic accident is also unavoidably risen thereupon, in the past by the traditional-handwork on-site measurement brake tire trace indirect calculation speed of a motor vehicle, judge and take brake measure whether proper effectively (is throttle or brake as what stepped at that time) etc. that the time is long, inaccuracy by rule of thumb, inconvenient, even because of the road conditions complexity, conditions environmental is limit, and technical evaluation work is brought very big uncertainty.Be difficult to make accurate objective science conclusion, for the identification of traffic accident technological analysis and responsibility is made troubles.

Summary of the invention

For this reason, the utility model adopts high-tech means, sensing technology, RF IC card technology are combined with computer technology, in the vehicle drive process, automatically in real time various vehicle condition parameter safety failure-freies are recorded in the electronic chip IC-card with special protection, has automobile " black box " function, can conveniently take out IC-card when needing, can read various desired datas at any time fast in any same instruments, the IC-card internal information is constant behind the read-out information, can read and write problems such as fine solution is above-mentioned repeatedly.

Drunken driving and fatigue driving are again the one of the main reasons of traffic accident, are the driving safety that is difficult to guarantee each automobile by traffic department's government with supervision only.

The utlity model has very strong expansion and extension function, as in conjunction with the drunken driving alarming device, the fatigue driving alarming device, can write down joy riding automatically, reference frame during as annual examination can increase the automobile burglar function again in conjunction with the software recognition system, implements the automation of traffic department's government and supervision with high-tech means, be scientific management standardization, the automation of traffic department, intellectuality provides reliable technique to guarantee.

The utility model provides a kind of electronic recording device, and technical scheme is achieved as follows: as Fig. 1, it comprises: one, vehicle condition sensory package 101,102,103,104, two, micro controller system 20, three, logger 30, four, situation display device 401,402.It is characterized in that being provided with in the vehicle condition sensory package speed sensor 101, braking sensor 102, throttle sensor 103, brake pump oil pressure sensor 104 all with micro controller system 20 in parallel linking to each other of I/O input port, signal has been amplified in each sensor and converted digital signal to by A/D again after integer is handled, will be separately in the running car real being sent in the micro controller system 20 during digital signal in the sensor, during data one road after micro controller system 20 is handled are delivered to and are write down in the logger, logger is characterized in that wherein being provided with non-contact radio-frequency IC-card read write line 301 and special IC-card 302, data (the special brevity code of time and each parameter after will handling by micro controller system 20, realize by software programming) by the induction of read write line 301 wireless radiofrequencies write in the special IC-card 302 (can divide in the card permanent information with the time reality information, permanent information such as driver are for information about, identity identification information and time on automobile starting date etc., the time real information write down each parameter information special compression brevity code in nearly 30 minutes repeatedly), and simultaneously status indication information is sent into demonstration in the status displays 401.Voice system 402 automatic speech promptings and warning are sent into after the machine analysis as calculated in another road.

In case accident takes place, speed is zero, speed sensor signal makes logger stop record, all vehicle condition data before this all with reservation record on IC-card, wherein free, the speed of a motor vehicle, what stepped at that time is that throttle or gate, brake pump oil pressure value judge whether its braking effectively normal.Owing to adopt the non-contact IC card radio frequency technology, IC-card can be encapsulated in to have in the special protective material, guarantee that special IC-card can not be damaged, information in the card can not lost yet, this card taken out with any identical read-only device of standard contactless IC card will obtain in the card at that time each initial parameter, and just can make the judgement of technological analysis and responsibility automatically by computing machine and corresponding software decoding.
