Embodiment Construction

[0014] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0015] As shown in Figures 1a and 1b, a GPS positioning alarm device includes a GPS correlator, a microprocessor, a memory, a real-time clock, and dual UARTs, which are connected to the control bus through an address bus, and also include a power supply and a reset controller. It is connected to a GPS correlator and a real time clock.

[0016] Existing 16-bit and 32-bit microprocessors, especially those from Motorola and Intel, and ARM60 32-bit RISC processors can be used.

[0017] The GPS correlator is a 12-channel correlator, its digital intermediate frequency data comes from the RF front end, and the control function is realized by a microprocessor.

[0018] As shown in Figure 2, it includes 12 tracking modules, a clock generator, a time base generator, an address decoder, a status r...

Abstract

The invention discloses a GPS position alarming device that includes GPS correlator, microprocessor, real-time clock and bi-UART (universal asynchronization receiving transmitting device), they are connected by the address bus and the control bus. The invention adopts the GPS position technique, so when the users alarming, it's no need to tell the location, the location can be obtained by the location signal of GPS, the people crying for help can get help timely.

Description

technical field [0001] The invention relates to a positioning alarm device utilizing GPS. Background technique [0002] GPS is the Global Positioning System (Global Positioning System), which was developed by the United States in the 1970s. It took 20 years and cost 20 billion U.S. dollars. A new generation of satellite navigation and positioning system with advanced capabilities. The use of my country's surveying and mapping departments in the past 10 years shows that GPS has won the trust of surveying and mapping workers with its all-weather, high-precision, automation, and high-efficiency features, and has been successfully used in geodetic surveying, engineering surveying, aerial photogrammetry, Vehicle navigation and control, crustal movement monitoring, engineering deformation monitoring, resource exploration, geodynamics and other disciplines have brought a profound technological revolution to the field of surveying and mapping. GPS satellites send two kinds of codes...
