Abstract

The invention discloses a remote positioning method based on an FPGA. According to the remote positioning method based on the FPGA, the GPS, data, short messages and other data are processed and control functions of modules of a vehicular-locating set are achieved by adopting an embedded microprocessor core of the FPGA to serve as a data processing and control core; an sim908 module is adopted and integrates GPS/GSM modules; a core of a soft-core processor is adopted and embedded into an FPGA construction; a soft core of a system is constructed in an SOPC builder of an NIOS II, and a hardware circuit diagram of the system is constructed in a quartus; a program is written in IDE software of the NIOS II. Positioning information received by the GPS modules is sent back through a serial port, then the positioning information is analyzed and sent to a user side through the GSM modules, and therefore the remote positioning method based on the FPGA is low in cost, wide in application range and flexible to apply.

Description

Based on the long range positioning method of FPGA

Technical field

The present invention relates to long range positioning field, particularly relate to a kind of long range positioning method based on FPGA.

Background technology

The U.S. is first and have developed GPS (Global Positioning System, GPS) country, in the seventies and eighties in 20th century, up-to-date Aerospace Satellite navigation positioning system is jointly developed by AUS, naval, three armies of air force, research and development technology along with FPGA becomes more and more ripe, and FPGA technology occupies obviously advantage at electronic applications.FPGA and field programmable gate array, be one and contain the semiconductor equipment can editing element, the logic gate array element stylized in the scene of being available for users to.It occurs as a kind of semi-custom circuit in special IC (ASIC) field, has both solved the deficiency of custom circuit, overcomes again the shortcoming that original programming device gate circuit number is limited.The market forecast of embedded system finds, the embedded system project being greater than 50% can not complete on time, the project of 1/3 only reach 50% performance and failure.

The embedded computing system (referred to as embedded system) of middle widespread use in a lot of fields, it is the computing system having repeated specific function embedded in larger electron device, it often not identify by the user of device, but these embedded systems can be found in various conventional electron device.Such as, mobile phone in consumer electronics product, pager, digital camera, video camera, video recorder, personal digital assistant etc., micro-wave oven in household electrical appliance, washing machine, baking box, gate control system, illuminator etc., card reader, scanner, printer etc. in commercial device.These embedded systems have several common characteristic: 1. single function; 2. tight restriction; 3. real-time reaction 4. software and hardware coexists.The long range positioning application of FPGA will improve the stability series of positioning system, increases economic efficiency and positioning accurate accuracy.

Summary of the invention

The present invention is based on the long range positioning method of FPGA, the method adopts the embedded microprocessor core of FPGA when being for data processing and control core, has been used for the process of data and the controlling functions to Vehicle mounted station modules such as GPS, data, short messages; Adopt sim908 module, it by GPS/GSM module integration together; Adopt the kernel of soft-core processor and it is embedded in the structure of FPGA; In the SOPC builder of nios II, construct the soft core of system, inside quartus, put up the hardware circuit diagram of system; Coding in NIOS II IDE software.

The embedded microprocessor core of described FPGA is made up of as data analysis and control core, data storage cell, power supply etc. the FPGA of GPS module, gsm module, embedded microprocessor:

GPS module is exactly the device that gps data receives;

Gsm module completes communication function by receiving formulation communication network, realizes this function by adopting the gsm module of access GSM mobile communications network.

Described sim908 module, together with module integrations different for GPS with GSM two, it combines gps satellite airmanship, adopts SMT encapsulation to be integrated with GRPS and GPS; Sim908 module adopts industry standard interface and GPS function, can realize any position of quorum sensing inhibitor and seamless tracking any time.

The described soft core constructing system in the SOPC builder of nios II is a kind of flush bonding processor, this processor is 32 systems, the design of nios II comprises hardware design and Software for Design two aspects, inside quartusII, realize the design of hardware components, in nios II IDE integrated design enviroment, carry out the design of software program.

The good effect that the present invention has is:

The locating information that GPS module receives by the present invention sends by serial ports, then after locating information being resolved, is sent to the long range positioning method of user side by gsm module, with low cost, is widely used system applying flexible.
