Wireless communication device for capturing motion signal of object and method for adjusting detection distance

Abstract

The invention provides a wireless communication device for capturing a motion signal of an object. The device comprises a main control chip, an AC-DC module, a DC-DC module, a DC-DC module, a radar module and a wireless communication module, wherein the AC-DC module U3 is connected with the DC-DC module and the DC-DC module. The DC-DC module U3 is connected with the radar module, the DC-DC moduleis connected with the main control chip, the main control chip is connected with the wireless communication module, and the radar module is in signal connection with the main control chip. The main control chip receives an object motion waveform sent by the radar module, compares the object motion waveform with preset motion waveforms of the object at different distances, determines whether the motion waveform is an interference waveform or not, and determines the motion distance of the object and the distance from the object to a radar. The device achieves the accurate measurement of an object distance, and reduces the false positive rate.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication device for capturing object motion signals and a method for adjusting a detection distance. Background technique [0002] The existing radar equipment that captures motion signals of objects is mostly used as electronic equipment in the military field, and it is also used in high-end industries such as weather forecasting, resource detection, and environmental monitoring in the direction of social and economic development, as well as scientific and technological fields such as celestial body research, atmospheric physics, and ionospheric structure research. Multiple applications. Spaceborne and airborne SARs have become very important sensors in remote sensing today. Radar targeting the ground can detect the precise shape of the ground. Its spatial resolution can reach several meters to tens of meters, and has nothing to do with distance. Radar ha...

Problems solved by technology

However, there is no economical product for large-scale promotion of technical solutions in the field of civil and commercial Internet of Things

[0003] The economic cost of manufacturing precision detection radar in the high-end field is too high to enter the civilian circulation market

Traditional civilian radar equipment needs to adjust the detection distance by changing the capacitance and resistance, which cannot adapt to various environmental changes, or requires engineers to manually adjust the hardware such as rheostats built into the equipment to change the detection distance, which greatly increases the amount of construction work.
