Abstract
The utility model relates to a multifunctional SIM kernel driver which comprises a microprocessor, a GPRS (general packet radio service) unit, a GPS (global position system) unit, an antenna, a synchronous dynamic random access memory and a Flash memory, wherein the GPRS unit, the GPS unit, the synchronous dynamic random access memory and the Flash memory are electrically connected with the microprocessor respectively. The antenna is connected with the GPRS unit. A mobile SIM card chip is made up of the microprocessor, the GPRS unit and the GPS unit. According to the multifunctional SIM kernel driver, the primary SIM card chip and the GPS unit are combined together, and a new SIM card is formed by mixing the functions of the primary SIM card chip and the GPS unit by the microprocessor, so that the functions of mobile communication and positioning are achieved, and the cost is saved.
Description
Technical field
The utility model relates to the processor technical field, is specifically related to a kind of multi-functional SIM kernel driver that is used for the SIM cards of mobile phones chip.
Background technology
Mobile phone is the abbreviation of (Subscriber Identity Module client identification module) with SIM, is also referred to as smart card, subscriber identification card, and mobile phone must be loaded onto this card and can use.It has stored digital mobile phone client's information on a computer chip, encrypted secret key and user's contents such as telephone directory can supply GSM network client identity to differentiate, and the voice messaging the when client conversed is encrypted.Along with expanding economy and the market-oriented condition of satellite navigation reach its maturity; Be equipped with in the mobile phone of GPS (Global Positioning System GPS) function also increasingly,, grasp traffic conditions in time from the transmission and the driver of traffic safety, logistics through this function; Even child loses or the household returns evening; Work efficiency has greatly been improved in its position of tram information acquisition that can utilize the GPS function to provide, for life brought convenient.But the ordinary GPS module is inlaid in the mobile phone, with SIM be two different processing systems, increased much with regard to the cost that makes mobile phone like this.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of multi-functional SIM kernel driver that can be used as the SIM cards of mobile phones chip of the GPS of carrying function.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Multi-functional SIM kernel driver; Comprise microprocessor, GPRS unit, GPS unit, antenna, synchronous DRAM, Flash storer; Said GPRS unit, GPS unit, synchronous DRAM, Flash storer electrically connect with processor respectively; Said antenna is connected with the GPRS unit, and the SIM cards of mobile phones chip is formed in wherein said microprocessor, GPRS unit, GPS unit.
Preferably, also comprise the display screen that electrically connects with microprocessor.
Preferably, said microprocessor is 32 embedded microprocessors based on the ARM framework.
Preferably, said GPRS unit is a CMS91 type GPRS module.
The multi-functional SIM kernel driver that the utility model is set forth; Compared with prior art; Its beneficial effect is: the utility model with former SIM chip and GPS unit combination together; Only the two function is merged the new SIM of composition and can realize the function of mobile communication and location, practiced thrift cost through a microprocessor.
Description of drawings
Accompanying drawing 1 is the structured flowchart of the multi-functional SIM kernel of the utility model driver.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the multi-functional SIM kernel driver of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
Particularly, 32 embedded microprocessors that microprocessor 11 adopts based on the ARM framework, the technical grade control chip S3C44BOX that can adopt Samsung is as microprocessor.This processor has abundant interface resource, can realize online programming, emulation, debugging, has guaranteed wireless location and the power of information interchange terminal and good debugging property based on GPS-GPRS.GPRS unit 13 adopts 10 grades of modules of a two-band GSM/GPRS, the CMS91 of Taiwan Cellon company.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
