VEHICLE TIRE TEST DEVICE
摘要:
The present application discloses a vehicle tire detection device, including a TPMS (Tire Pressure Monitoring System) sensor, an antenna matching network, and a terminal antenna. The TPMS sensor uses ASK/OOK/FSK transmission technology with a data transmission rate greater than 20kbps. The TPMS sensor is connected to the terminal antenna through the antenna matching network. The terminal antenna is one of a valve stem, a metal base, or a tire rim. In the present application, by enhancing a radio frequency data transmission rate, an aim is to reduce a radio frequency transmission time of the sensor, thereby reducing a transmission power consumption. By shortening the transmission data time, an aim is to enhance a signal transmission penetration and improve a radio frequency anti-interference capability. Using a valve stem, metal base, or tire rim as the terminal antenna enhances a length and area of the antenna, leading to higher signal conversion efficiency and better transmission stability of the sensor on the vehicle. The terminal antenna being on the outside of the tire body is beneficial for increasing the strength of the wireless signal, with the same transmission power of the TPMS sensor, it is easier to achieve wireless communication over a longer distance, and the error rate is reduced.
