Description

Can discern two generation smart identity cards automobile travel recorder

Technical field

The utility model relates to a kind of equipment that writes down the running car situation, relate in particular to a kind of can discern two generation smart identity cards automobile travel recorder.

Background technology

The topmost function of automobile travel recorder (hereinafter to be referred as registering instrument) is to prevent that vehicle " hypervelocity; overtime " from travelling, drive over the speed limit when vehicle is in, during state violating the regulations such as fatigue driving, registering instrument can be reminded the driver should reduce the speed of a motor vehicle or stop in modes such as sound, light and have a rest.If traffic hazard, traffic control department " hypervelocity, overtime " record in can the playback record instrument is implemented corresponding punishment to traffic violation person.But same vehicle has a plurality of driver's timesharing to be driven, so driver's identification is particularly important, if there is not reliable identity identification measure, entanglement will appear in record violating the regulations, can not reach the purpose of " the pipe car is at first managed the people ".At present, domestic most of registering instrument producer adopts IC-card to realize identification usually, and promptly each driver joins an identity IC-card, plugs the IC-card of oneself when driving, so that registering instrument carries out identification.The defective of IC-card identity recognizing technology is: IC-card must have slot when using, and in abominable vehicle environment, dust and water smoke are easy to enter into registering instrument inside by slot, reduces the registering instrument life-span; Supervisory computer must have card reader when IC-card is carried out reading and writing data, and card reader must take computer resource, operates very loaded down with trivial details; The confidentiality of IC-card is bad, is easy to revise interior data; In addition, each driver self has the equipment of a lot of similar IC-cards, such as bank card, the card of paying the fees, road and bridge card, phonecard, dining room mess card etc., therefore, the driver also very dislike re-use IC-card and carry out identification.

Second generation resident identification card has been enabled a period of time, compares the previous generation I.D., and its scientific and technological content is higher, and canned data is abundanter, uses also more convenient.Second generation smart identity cards adopt contactless IC-card fabrication techniques, utilize chip as machine-readable storer, and chip storage capacity is big, the information that writes can be divided into safe class, the subregion storage is read and write according to the managerial demand mandate, also transition information (as address change) can be appended to write; The logical encrypt algorithm that chip uses, the system that helps certificate send out and use in safety management, strengthened antiforge function.

The utility model content

The characteristics and the advantage that are possessed based on problems of the prior art and second generation smart identity cards, the utility model proposes a kind of can discern two generation smart identity cards automobile travel recorder, its structure is: it is by microprocessor, storer, display screen, clock circuit, operating key, the RS232 telecommunication circuit, the I.D. read module, the USB flash disk module for reading and writing, speed pickup is formed, wherein, microprocessor respectively with storer, display screen, clock circuit, operating key, the RS232 telecommunication circuit, the I.D. read module, the USB flash disk module for reading and writing, speed pickup connects.

Useful technique effect of the present utility model is: data security is strong, can't change, and need not to be provided with slot and fabrication separately, and is easy and simple to handle.

Embodiment

Referring to Fig. 1, the utility model structure is made up of microprocessor, storer, display screen, clock circuit, operating key, RS232 telecommunication circuit, I.D. read module, USB flash disk module for reading and writing, speed pickup, wherein, microprocessor is connected with storer, display screen, clock circuit, operating key, RS232 telecommunication circuit, I.D. read module, USB flash disk module for reading and writing, speed pickup respectively.

Wherein, the I.D. read module is used for the identity of identification of driver; The USB flash disk module for reading and writing is used for data acquisition, and the record data that will travel write in the USB flash disk, is convenient to system software and carries out data analysis; The RS232 telecommunication circuit is used for equipment and host computer communicates, as time, vehicle parameter setting, upload data etc.; Speed pickup becomes vehicle velocity signal into electric impulse signal, so that microprocessor carries out speed and mileage calculates; Clock circuit provides current real-time clock to microprocessor, for the data analysis of back provides basis of time; Storer is used for store car correlation parameter and corresponding driver's data, and the data of storage can directly download in the USB flash disk by the USB flash disk module for reading and writing, also can directly upload in the computing machine by the RS232 telecommunication circuit; Display screen shows vehicle current driving data; Operating key is used for man-machine conversation.

Referring to Fig. 2, behind the driver Deng Che, start registering instrument, registering instrument is discerned I.D., if there is not relevant I.D. record, then newly-built archives also carry out record to data, if existing relevant I.D. record then calls associated profiles and data are carried out record; The data that record are transferred to management system, and generate form.Also registering instrument and steer can be bound, make steer controlled by registering instrument, have only I.D. the match is successful to start steer.

Claims (1)

1. One kind can discern two generation smart identity cards automobile travel recorder, it is characterized in that: it is made up of microprocessor and the storer that links to each other with microprocessor respectively, display screen, clock circuit, operating key, RS232 telecommunication circuit, I.D. read module, USB flash disk module for reading and writing, speed pickup.
