Detection and sensing device used for timing of motor racing

Abstract

The invention relates to a detection and sensing device used for timing of motor racing. The detection and sensing device comprises an excitation unit, vehicle units, a receiving and forwarding unit and a computer which are successively connected, wherein each vehicle unit comprises a reception and trigger circuit, an ID code transmission control unit and a RF transmitting circuit which are successively connected, the reception and trigger circuit is connected with the excitation unit, and the RF transmitting circuit is connected with the receiving and forwarding unit. The receiving and forwarding unit generates a trigger signal after excitation by electromagnetic waves transmitted by the excitation unit; the trigger signal triggers the ID code transmission control unit; the inherent ID code of each vehicle unit is transmitted to the receiving and forwarding unit via the RF transmitting circuit; the receiving and forwarding unit forwards the received ID code to the computer; and the computer stores the time value of a current moment and the ID code into corresponding forms in a database. Compared with the prior art, the detection and sensing device provided by the invention has the advantages of improved reliability and accuracy, etc.

Description

technical field [0001] The invention relates to a racing timing device, in particular to a detection and sensing device for racing timing. Background technique [0002] Car racing is a sports event that pursues speed and extremes. It includes many dynamic events such as straight-line acceleration, high-speed obstacle avoidance, figure-of-eight circles, durability and fuel economy. It is extremely important to clearly grasp the driver's training situation in the usual racing training, and it is an important basis for judging the performance during the competition. Therefore, it is necessary to have a set of timing devices that can be used exclusively for this event, so as to easily and conveniently understand the driver's driving situation and various aspects of the performance of the car; it is an important timing tool for various car races. At present, there is no relatively systematic and complete timing system dedicated to this event in China. Mechanical or electronic ti...
