Title:
DISCHARGE CIRCUIT FOR DISTANCE MEASURING DEVICE, DISTRIBUTED RADAR SYSTEM AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2020/142956
Kind Code:
A1
Abstract:
Provided are a discharge circuit (200) for a distance measuring device, a distributed radar system (100) and a mobile platform, wherein the discharge circuit (200) for the distance measuring device is used to discharge when an input power supply (VIN) is powered off, the discharge circuit (200) comprises: a comparison module (20), which is used to compare the magnitude of a voltage divider (VIN1) generated by the input power supply (VIN) with a reference voltage (VREF), and generate a comparison signal (VOUT1); a direction detection module (30), which is used to generate a detection signal (VQ) indicating whether the input power supply (VIN) is in a power-off state or a non-power-off state according to the comparison signal (VOUT1); and a discharge module (40), which is used to determine whether to discharge according to the detection signal (VQ). The direction detection module (30) determines whether the input power supply (VIN) is in the power-off state or the non-power-off state, so that it does not operate during power-on of the input power supply (VIN) to ensure that a power supply circuit is fully charged quickly, without additional energy loss, and operates during power-off of the input power supply (VIN) and discharges the residual charge on the power supply circuit to ensure the stability of a circuit system.
