Problems solved by technology
One-to-one matching between antennas and tires, such as the scheme described in patent CN201180006751, is only applicable to single-wheel vehicles. For vehicles with multiple wheels, adjacent antennas will interfere with each other, resulting in inaccurate detection results.
For the detection of tire pressure matching, such as the scheme described in patent CN202010865768, in this scheme, it is considered that the signal with a lower mean value of the tire pressure signal comes from the outer tire, and the signal with a higher mean value of the tire pressure signal comes from the outer tire, and the sensor is completed accordingly. Matching with tires, in this method, because the tire pressure is greatly affected by the external environment, it is difficult to ensure the accuracy of matching between sensors and tires

Embodiment 1
[0081] Such as Figure 1-2 As shown, an identification structure of a freight vehicle tire sensor includes an excitation antenna, a connection line, a signal transceiver, a cloud server, and an application terminal; wherein the excitation antenna is arranged near the vehicle tire; the connection line is arranged between the excitation antenna and the signal transceiver Between the devices; the signal transceiver is also connected to the cloud server, and the cloud server is also connected to the application terminal.
[0082] The excitation antenna is used to transmit and receive signals, wherein the transmitted signal will be received by the sensor inside the license plate, and the sensor will be excited to make the sensor send a feedback signal; the feedback signal sent by the sensor will also be received by the excitation antenna, and through the connection The line is transmitted to the signal transceiver. For a single wheel, the exciting antenna is set near the single wh...

The invention relates to an identification structure and a positioning method of a freight vehicle tire sensor, which are particularly suitable for the condition that a commercial vehicle has multiple wheel positions and multiple wheels exist, an excitation antenna is arranged, the excitation antenna is connected with a signal transceiver through a connecting line, and the signal transceiver controls the excitation antenna part to send out an excitation signal; a sensor in a tire is excited, a feedback signal of the sensor is received by an excitation antenna and transmitted back to a signal transceiver, the number of the sensor is judged according to the feedback signal, and wheel position preliminary judgment of the sensor is achieved; and the data received by the signal transceiver is uploaded to the cloud server for further processing, and a processing result is sent to the application terminal, so that the accurate position identification of each sensor is completed.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an identification structure and a positioning method of a freight vehicle tire sensor. Background technique [0002] In current vehicles, sensors are often installed inside the tires to monitor the real-time status of the tires and ensure the driving safety of the vehicle. Among them, because the sensor and the tire are in one-to-one correspondence, it is necessary to complete the matching of the sensor and the tire; otherwise, even if the information of the sensor is received, it is impossible to judge which tire is the information. [0003] The current matching of sensors and tires includes code scanning matching, automatic acceleration detection matching, antenna and tire one-to-one matching, and tire pressure detection matching. Among them, the scanning code matching method is relatively cumbersome, and the matching effect will be affected after the two-dimensional code on the tir...
