Abstract

The invention provides a real-time tracking device and a real-time tracking method for a space track, and relates to the technical field of tracking of a three-dimensional space track. The device comprises a sensor, a microcontroller, and a universal asynchronous receiver and transmitter controller, wherein the sensor comprises a tri-axial acceleration sensor, a three-axis gyroscope and a three-axis electronic compass; the sensor transmits sensing data to the microcontroller through an inter-integrated circuit (IIC) interface; the microcontroller is used for receiving and processing the sensing data transmitted by the sensor, and transmitting a control command to the sensor through an IIC bus; meanwhile, the processed sensing data are transmitted to the universal asynchronous receiver and transmitter controller through a universal asynchronous receiver/transmitter (UART) periphery; the universal asynchronous receiver and transmitter controller converts the processed sensing data transmitted by the microcontroller, and transmits to a host computer through a universal serial bus (USB) interface; meanwhile, the universal asynchronous receiver and transmitter controller converts the command transmitted to the host computer and then transmits to the microcontroller. The device and the method are low in cost, high in stability and high in accuracy, and the device is small in size and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of three-dimensional space trajectory tracking, in particular to a space trajectory real-time tracking device and method. Background technique [0002] With the economic development of society, the field of real-time tracking technology of space trajectory can be applied more and more widely. For example, large shopping malls are located in various commercial districts of the city. When shopping in large shopping malls, consumers will find a dazzling array of shops, such as for underground construction workers and rescuers for underground accidents. , it is very necessary for a device to help them locate and navigate; another example is that some mines and oilfield devices need to track the moving distance of the device, and use a ruler to measure the working status and performance indicators of the device that cannot be quickly determined; there are also universities that do Various physical experiments ne...
