Abstract

A vehicle-mounted global position system (GPS) wireless terminal kernel module comprises a GPS module, a power source module, a loaded functional module and a central processor, and is characterized in that the central processor is an industrial grade dual-core global system for mobile communications (GSM) module, the GPS module is connected to the industrial grade GSM module in an information transmission mode, and the GSM module achieves communication and input-output (IO) interface connection with the loaded functional module through an interface chip. According to the vehicle-mounted GPS wireless terminal kernel module, the product structure is modified from the perspective of the product framework. Due to the fact that the kernel module is small in size and low in power consumption, the finished product is small in size, and installation space in a vehicle is saved. Meanwhile, the power consumption is decreased by 60 percents compared with similar products. In addition, integrated level is high, and the number of connectors of a traditional vehicle-mounted terminal is reduced, so that reliability of shock-prevention performance of the product is reinforced. Strong multimedia function and abundant interfaces enable the application of the product to be broader.

Description

Vehicle GPS wireless terminal nucleus module

Technical field

The utility model relates to GPS terminal equipment, relates in particular to the application of technical grade double-core framework GSM nucleus module at the vehicle GPS wireless terminal.

Background technology

The vehicle GPS wireless terminal all is widely used in every field through years of development.Development along with the car networking technology; The vehicle GPS wireless terminal develops into the go recorded information of realization to vehicle, vehicle condition information, GPS/GIS information from simple GPS location and alerting signal transmission; Vehicle safety information; Multimedia messagess such as image voice are integrated the networking transmission with mutual, in enterprising administration-management reason of powerful data platform and data analysis, reach the purpose of the comprehensive management of vehicle.

Traditional vehicle GPS wireless terminal is made up of GSM communication module, GPS module and single-chip microcomputer, because the restriction of single-chip microcomputer processing power; Many multimedia messages processing need to increase in addition the multimedia process chip, and the CPU on car-mounted terminal has no doubt improved the processing power and the arithmetic speed of wireless terminal, has but greatly wasted the energy; The part resource is also arranged by idle and can not get utilizing well; Generally speaking, the inner maincenter of car-mounted terminal cause integrated level not high, product energy consumption is big.

Summary of the invention

The utility model has proposed the vehicle GPS wireless terminal nucleus module that a kind of system architecture is simplified, integrated level is high, the product power consumption is little to above problem.

The technical scheme of the utility model is: a kind of vehicle GPS wireless terminal nucleus module; The functional module and the center processor that comprise GPS module, power module, loading; It is characterized in that; Said center processor is a technical grade double-core gsm module, and said GPS module information conduction-type is connected to the technical grade gsm module, and said gsm module realizes that through the interface chip and the functional module of loading communication is connected with the IO mouth.

The functional module of said loading comprises display screen and key-press module, communication interface, automobile running record IO interface, voice and conversation interface, video interface, CAN bus, printer module, IC-card recognizer and the SD storage card that same level is arranged side by side.

The beneficial effect of the utility model is: simplified product structure from the product framework, because this nucleus module volume is little, low in energy consumption, made the small product size of final production very little, saved the vehicle installing space.Simultaneously power consumption has reduced by 60% than like product, and in addition, integrated level improves, and has reduced the connector of traditional vehicle mounted terminal, makes that the reliability of resistance vibration of product is strengthened.The strong multimedia function makes the application of product more extensive with abundant interface.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.

Embodiment 1:

A kind of vehicle GPS wireless terminal nucleus module; The functional module and the center processor that comprise GPS module 1, power module 2, loading; It is characterized in that; Said center processor is a technical grade double-core gsm module 3, and said GPS module 1 information conduction-type is connected to technical grade gsm module 3, and said gsm module 3 realizes that through interface chip 4 and the functional module that loads communication is connected with the IO mouth.In vehicle GPS; The GPS function that mainly has realizes through the GPS module; In original technology, be omitted fully as the process chip of supporting processing power to need just to load; And replaced by the GSM nucleus module, adopt technical grade double-core framework gsm module in the utility model, utilize the ability of the CPU+DSP process chip that performance is powerful in the gsm module to replace the effect of large multimedia process chip.Further realize vehicle GPS wireless terminal compression of images, audio compression, TTS phonetic synthesis, preset multimedia function such as voice suggestion.

The concrete multimedia function that can accomplish is to accomplish through the functional module that on the GSM basis, loads, and the functional module of said loading comprises display screen and key-press module 5, communication interface 6, automobile running record IO interface 7, voice and conversation interface 8, video interface 9, CAN bus, printer module 11, IC-card recognizer 12 and the SD storage card 13 that same level is arranged side by side.

The utility model technical grade double-core framework GSM nucleus module is to adopt the leading integrated CPU of one chip of new generation (containing analog-and digital-base band, RF transceiver, power management and audio codec at a single monolithic integrated optical circuit); It supports the GSM/GPRS radio communication of Quad Band (GSM 850/EGSM 900/DCS 1800/PCS 1900) as the GSM communication module; Support embedded TCP/IP; GPRS partly is B, C class class10; GPRS transfer table (supporting CS1, CS2, CS3, CS4) has functions such as abundant voice, note, data service.

The high performance ARM9 chip of while inner high speed, interior band dsp processor can be realized encoding and decoding speech and GSM A3/A5 algorithm high speed processing.Through CPU built-in High Speed I-CACHE and D-CACHE, and make full use of the BURST pattern of FLASH and PSRAM, improved the comprehensive treatment capability of processor greatly.Can realize that to AMR the hard coded hard decoder of MP3 has enriched functions of modules.Host CPU itself provides abundant interface, like I2C, and SSI, SIM (ISO7816), UART (speed can reach about 1.5MBPS), GPIO etc.A large amount of peripherals can be connect, complicated steering logic can be realized.
