Abstract

The utility model relates to a vehicle-mounted intelligent card used for automatically recording information on the speed and location of a vehicle with a GPS. In the technical scheme, a memory devicecomprises speed memory space, location memory space and time memory space, which are respectively used for storing information on the instantaneous speed, location and time obtained through a GPS module. During the data recording process, the GPS is used for obtaining the information on the location and speed of the vehicle and then automatically storing the information. During the information extraction process, the information stored can be provided for other external devices to monitor the running state of the vehicle. The utility model can be used in the vehicle speed monitoring and management as well as the failure analysis of the vehicle involved in the accident in the highway and other fields.

Description

A kind of vehicle intelligent card

Affiliated technical field

The utility model relates to a kind of pen recorder of information of vehicles, especially automatically the vehicle-mounted recording card of information such as registration of vehicle speed and position.

Background technology

At present, known car speed monitoring means are to use the velocity radar fixed point to monitor, and carry out record with the method that camera is taken pictures.But this method need be installed the photographic means that tests the speed in appointed positions, and quantities is bigger on the one hand; Speed measuring function can't be realized in the place that does not have speed measuring point on the other hand, the complete monitoring of vehicle can't be realized.And a part of driver adopts stickup, alters even removes the way escape of car plate and takes pictures.Brought inconvenience to traffic administration, for traffic safety stays hidden danger.

Summary of the invention

In order to overcome the deficiency of existing car speed monitoring means, the utility model provides a kind of vehicle intelligent card, this vehicle intelligent card is in conjunction with GPS and modern electronic technology, the real-time speed of monitoring vehicle that can not only be real-time comprehensively, and can be easily the positional information of itself and vehicle be combined, for vehicle management provides more fully foundation.In addition, this smart card does not need fixing device for installing on the way, and quantities is little, can be conveniently used in highway, urban district or other road managements.

The technical scheme that its technical matters that solves the utility model adopts is: adopt a kind of vehicle intelligent card, it comprises power supply, logic control element, GPS module, memory device and communication facilities several sections.Logic control element wherein is connected with GPS module, communication facilities and memory device respectively, and is powered by power supply.Comprise speed storage space, location storage room and time storage space in the memory device, be respectively applied for instantaneous velocity, position and temporal information that preservation obtains from the GPS module.Instantaneous velocity of preserving in the memory device and position are corresponding one by one with the time.

The application of this vehicle intelligent card is divided into data recording process and information extraction process two parts.In data recording process, by logic control element the information such as real-time speed, position and time that the GPS module obtains are kept in the memory device, thereby preserve the record of all relevant informations in the vehicle ' process.Instantaneous velocity of preserving in the memory device and position are corresponding one by one with the time, and the instantaneous velocity of different time and positional information grouping are deposited; In information extraction process, by logic control element control these information are extracted, and give the external world by communication facilities, use for other external units or system.Thereby finish monitoring to vehicle traveling information.

In the scheme, the GPS module is finished obtaining of information, and memory device is realized the storage of information, and communication facilities is responsible for canned data is offered other external units or system, and logic control element is finished the coordination and the control of entire equipment.

The beneficial effects of the utility model are, can testing the speed takes pictures realize the monitoring fully and the record of vehicle running state under the prerequisite of network not setting up, and do not need to be connected with any system of vehicle body, simple in structure, easy to use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is a system chart of the present utility model.

Accompanying drawing 2 is memory device structured flowcharts of first embodiment of vehicle intelligent card.

Accompanying drawing 3 is memory device structured flowcharts of another embodiment of vehicle intelligent card.

The utility model comprises logic control element, GPS module, memory device, communication equipment and power supply. Storage is wherein established Standby formed by speed memory space, position memory space and time memory space, be respectively applied to preserve from the GPS module obtain namely Shi Sudu, position and temporal information. The instantaneous velocity of preserving in the memory device and position are one by one corresponding with the time.

Embodiment

In Fig. 1, power supply links to each other with GPS module, logic control element and memory device respectively, for it provides energy.Logic control element links to each other with GPS module, communication facilities and memory device respectively.Memory device wherein is made up of speed storage space, location storage room and time storage space, is respectively applied for instantaneous velocity, position and temporal information that preservation obtains from the GPS module.Instantaneous velocity of preserving in the memory device and position are corresponding one by one with the time.Wherein memory device will have enough spaces to guarantee to preserve abundant data message.Communication facilities can be simple communication interface, also can be made up of the communication interface chip of special use.

Logic control element can be by Single Chip Microcomputer (SCM) system or FPGA specific implementation.If adopt Single Chip Microcomputer (SCM) system to realize logic control element, in data recording process, single-chip microcomputer extracts and stores into information such as the position that obtains in the GPS module, speed in the memory device; In information extraction process, single-chip microcomputer extracts the information data of preserving in the memory device and transmit to the external world by communication facilities.If adopt FPGA to realize logic control element, in data recording process, extract and store into information such as the position that obtains in the GPS module, speed in the memory device by FPGA; In information extraction process, FPGA extracts the information data of preserving in the memory device and transmit to the external world by communication facilities.

In embodiment illustrated in fig. 2, the storage space of vehicle intelligent card is divided into speed storage space, three parts of location storage room and time storage space.Each speed, position and time constantly is stored in separately the space one to one.Three storage spaces interlock in the present embodiment.Promptly depositing constantly 1 speed, position, corresponding concrete time successively, is 2 speed, position and corresponding concrete time constantly then, by that analogy, finishes up to all deposit data.

In the embodiment shown in fig. 3, the storage space of vehicle intelligent card is divided into speed storage space, three parts of location storage room and time storage space equally.Each speed, position and time constantly is stored in separately the space one to one.Three storage spaces are separate in the present embodiment.Promptly deposit 1 speed, the speed in the moment 2 constantly successively ..., be position, the position in the moment 2 in the moment 1 then ..., be each corresponding constantly concrete time at last.Because the length of concrete data can't be determined, must reserve enough big vacant position in each storage space back when adopting separate storage space.
