Arduino-based high-precision GPS time service positioning system

Abstract

The invention discloses an Arduino-based high-precision GPS time service positioning system, which comprises a main controller and modules, wherein the main controller is an Arduino UNO3 development board, and the working modules comprises an LCD display screen, a GPS module, a voice module and a loudspeaker; the Arduino main controller comprises an MCU chip, an analog IO, a digital IO and a serial port; the Arduino main controller is connected with the LCD display screen and the voice module through the digital IO, and the GPS module is connected with the Arduino main controller through the serial port; the GPS module is connected with information received by a satellite and transmits the information to the main controller through the serial port; and the main controller extracts standardGreenwich time information and real-time longitude and latitude information from the information, converts the time into Beijing east eighth zone time, sends the processed time information to the display screen for display, and can broadcast real-time information at a set time point. According to the Arduino-based high-precision GPS time service positioning system, GPS time service positioning isused, the precision is high, manual time adjustment is not needed, automatic time calibration and automatic positioning can be realized; time and location information are detailed; and the Arduino-based high-precision GPS time service positioning system uses the Arduino as the main controller, is more intelligent, expandable, high in transportability and easy to use, uses a voice chip, can broadcast in real time, and is more intelligent.

Description

technical field [0001] The invention belongs to the field of precision electronic equipment for automation systems, and relates to an Arduino-based high-precision GPS timing and positioning system. Background technique [0002] With the rapid development of economy and technology in today's world, the concept of time and location has become more and more important factors in people's daily life and work. Therefore, the demand for precise time and precise positioning is becoming more and more extensive, especially for outdoor precision in electronic equipment. Most of the current high-precision timing and positioning devices need to be connected to the Internet to automatically correct the time and refresh the location information, and the cost is expensive. In some extreme environments, it does not work normally, the time error is large, and accurate positioning cannot be performed. With the rise of the Internet of Things and embedded devices in recent years, Arduino, whic...
