Wireless power and signal receiving and transmitting device of lamplight test instrument

Abstract

The invention discloses a wireless power and signal receiving and transmitting device of a lamplight test instrument. The wireless power and signal receiving and transmitting device comprises a communication charge device, a first positive electrode, a first negative electrode, a first infrared transmitter and a first infrared receiver, wherein the communication charge device comprises a communication controller, a second positive electrode, a second negative electrode, a second infrared receiver and a second infrared transmitter; the communication controller is connected with the second infrared receiver and the second infrared transmitter respectively; the second positive electrode and the second negative electrode are connected with an external power supply respectively; the first positive electrode and the first negative electrode are connected with a battery set of the lamplight test instrument respectively; and the first infrared transmitter and the first infrared receiver are connected with a lamplight instrument controller of the lamplight test instrument respectively. The wireless power and signal receiving and transmitting device has the advantages as follows: a wireless signal can be randomly received or transmitted in free space and is not easily interfered by surrounding electric appliances and human factors, the inconvenience caused by external connection of excessive electric wires is avoided at the same time, and the convenience is provided for operation of the instrument.

Description

technical field [0001] The invention belongs to the field of motor vehicle light testing, and relates to a wireless power and signal transceiving device for a light tester. Background technique [0002] Motor vehicle headlights are important equipment for motor vehicle drivers to provide lighting when a motor vehicle is driving at night or in dark conditions. It is crucial to the safe driving of motor vehicles. According to national standards, when all the headlights of a motor vehicle are illuminated at the same time at night, the driver should be able to see clearly the traffic obstacles within 100 meters ahead. To meet this requirement, the light intensity and irradiation direction of the headlights are very important. At present, a motor vehicle light tester is usually used to detect the light intensity and irradiation direction of a motor vehicle headlamp. [0003] Most of the existing motor vehicle lighting testers are driven by motors, and the motors are...

Problems solved by technology

[0003] Most of the existing motor vehicle lighting testers are driven by motors, and the motors are directly connected to the external power supply through wires. At the same time, the signal of the lighting tester is mainly transmitted by wire, which means that when using the tester, it must be connected to an external power supply. A large number of wires and cables bring great inconvenience to the walking of the light tester during the detection process
