Design Of GPS Receiver System Based On Dual Processor

With the frequent occurrence of geological hazards in China,the monitoring and early warning of geological hazards has gradually become a research hotspot.Among them,GPS technology has become the main method for geological disaster detection and early warning because of its all-weather and high accuracy.However,there are many deficiencies in the existing equipment on the market,which are mainly manifested in poor environmental adaptability,weak fault detection capability,and weak anti-theft capability.Therefore,this paper studies the design of GPS receiver system based on dual processors.This thesis first analyzes the system requirements,then proposes the design of the receiver,then refines the hardware design and firmware design,and finally completes the system testing and verification.In terms of solution design,a dual-processor-based GPS receiver system is proposed.The system uses a dual processor architecture to share system tasks and is designed with components such as temperature control modules,anti-theft modules and storage modules.In terms of hardware design,the system's hardware design concept,circuit design ideas,schematic diagrams,and PCB design points are mainly introduced from three aspects: front panel design,interface board design,and backplane design.Among them,the backplane is the key board of the GPS receiver system,which is described in detail in this article.In terms of firmware design,this paper mainly introduces the system's firmware design concept,design ideas,and program writing process from the two aspects of the main control machine and the business machine.It also focuses on the firmware architecture of the dual processors and how they communicate with each other.In terms of testing and verification,starting from the three aspects of system hardware test,unit test and whole machine test,power test and function test are performed on each working module of the system,and then the entire GPS receiver system is tested to verify its workability.And reliability.The GPS receiver proposed in this article has functions such as temperature monitoring and adjustment,electronic anti-theft,information storage,and SMS interaction.It has stronger working stability and environmental adaptability,and can better perform functions such as fault self-test and anti-theft alarm.Related research provides a reference.
