Outdoor Wearable Global Satellite Positioning Device

technical field

The invention relates to the field of positioning equipment, in particular to an outdoor wearable global satellite positioning equipment.

Background technique

Wearable technology is an innovative technology proposed by the Massachusetts Institute of Technology Media Laboratory in the 1960s. Using this technology, technologies such as multimedia, sensors, and wireless communications can be embedded in people's clothing, and it can support gestures and eye movements. way of interaction. Wearable technology has always attracted much attention in the international computer academic and industrial circles, but due to the high cost and technical complexity, many related devices only stay in the conceptual field. In recent years, with the development of the mobile Internet, technological progress, and the introduction of high-performance and low-power processing chips, some wearable devices have moved from conceptualization to commercialization. Reports on wearable devices continue to spread. Google, Apple, Microsoft , Sony, Olympus and many other technology companies have also begun to explore in-depth in this new field. Recently, Forrester Research, an independent market research firm, pointed out that the next computing revolution will come from "wearable devices" instead of smartphones and computers.

Wearable smart devices have come into reality from fantasy, and their appearance will change the life style of modern people. With the rapid development of standardized computer hardware and software and Internet technology, the form of wearable smart devices has become diversified, and has gradually shown important research value and application potential in many fields such as industry, medical treatment, military affairs, education, and entertainment.

The electronic compass compass module includes a three-axis accelerometer and a compass, and the output end of the three-axis accelerometer is connected to the compass; the output end of the compass is connected to the controller. The three-axis accelerometer uses the ADXL345 three-axis acceleration module. With ultra-low power consumption: when VS=2.5V (typical value), the measurement mode is as low as 23ìA, and the standby mode is 0.1μA. The power consumption automatically changes proportionally with the bandwidth and the user-selectable resolution. Through a three-axis geomagnetic sensor and a three-axis acceleration sensor. Realize the detection of the inclination of the equipment, and then make inclination compensation for the parameters of the electronic compass to reduce the error. The compass uses the HMC5883 compass module: this module mainly considers the interference of the magnetic field of the correction device itself, so that the measurement data is more accurate.

The air pressure sensor uses BMP085 to not only measure atmospheric pressure in real time, but also measure real-time temperature. At the same time it also has the interface of IIC bus. MS5611-01BA03 is a new generation of high-resolution altimeter sensor designed and produced by MEAS Company. It provides SPI interface and I2C bus interface. The high resolution of 10cm makes it more suitable for altitude measurement and barometric pressure measurement. The sensor module includes a high linear pressure sensor and a 24-bit low-power AD converter, and the sensor contains factory calibration coefficients. It provides an accurate 24-bit pressure and temperature value. Different operating modes allow the user to optimize conversion speed and current consumption. The sensor has the function of temperature measurement while measuring air pressure. MS5611-01BA03 can be connected to almost all microcontrollers, the communication protocol is simple, and the internal programming memory of the device is not required. Small size for easy application integration.
