The invention discloses a device and a method for verifying a parking online querier by a vehicle-mounted transponder. The device is composed of a verification vehicle, a guide frame, a power unit, alaser ranging unit, a transponder uplink signal receiving unit, a transponder and a signal processing main control unit, wherein the vehicle-mounted mobile transponder and a static querier replace a static transponder and a vehicle-mounted mobile querier, so on-site verification of the parking online querier can be implemented, a crawler-type verification vehicle is guided and positioned through combination of horizontal guide wheels and spring damping type oblique supporting wheels, the transponder passes through the position under a query antenna of a query device, and verification precisionand reliability are improved. The transponder uplink signal receiving unit and the laser ranging unit are configured so that positioning precision and an operating distance of the transponder can beinquired, and the transmitting function of the inquirer can be verified, a brushless direct current motor of the verification vehicle executes speed-current double closed-loop control, the motion quality of the verification vehicle is improved, and verification precision and reliability are further improved.
本发明公开一种车载应答器验证存车线上查询器的装置和方法。装置由验证车、导向架、动力单元、激光测距单元、应答器上行信号接收单元、应答器、信号处理主控单元组成。车载移动应答器和静止查询器替代静止应答器和车载移动查询器,使存车线上查询器的现场验证得以实施;履带式验证车采用水平导向轮和弹簧减震式斜向支撑轮的组合导向定位,应答器从查询器的查询天线正下方通过,提高了验证的精度和可靠性;配置应答器上行信号接收单元,激光测距单元,可获查询‑‑应答器的定位精度、作用距离,验证查询器的发射功能;验证车的无刷直流电机执行速度‑电流双闭环控制,改进了验证车的运动品质,进一步提高了验证的精度和可靠性。
