Problems solved by technology

[0006] 1. The system is relatively complicated. The front part needs to install a code reader and a trailer information receiving circuit, and it needs to lead to the rear of the front part, so the amount of wiring harness installed in the front part has not been significantly reduced;

Embodiment Construction

[0028] Because many trucks have trailers and head replacements, the tires of the same system are not fixed, that is to say, the tires monitored by the system are not fixed. However, relatively speaking, the tires of the front and the trailer are basically unchanged. Therefore, according to an embodiment of the present invention, a tire pressure monitoring system (TPMS) is proposed, which is registered wirelessly by setting a code register , It fully realizes the replacement of trailers automatically identified by the system, and it is very easy to install and use.

Abstract

The invention relates to a tire pressure monitoring system, which is suitable for an automobile with a first component and a replaceable second component. The tire pressure monitoring system comprises a register, a repeater and a receiver. The register is used for wirelessly transmitting a registration code corresponding to the automobile; the repeater is arranged on the second component and is used for forwarding second tire information transmitted by a tire pressure transmitter for each tire on the second component, and when the repeater receives the registration code, the second tire information is added to the registration code and then is forwarded; and the receiver is arranged on the first component and is used for receiving the second tire information, wherein when the registrationcode contained in the second tire information is consistent with the registration code of the automobile saved by the receiver, the receiver uses the second tire information as the tire information of the automobile for processing. The tire pressure monitoring system can realize the registration during exchanging a trailer of a truck in a simplified and reliable mode.

Description

technical field [0001] The invention relates to an automobile tire pressure monitoring system (TPMS system), in particular to a TPMS system suitable for trucks whose trailers are frequently replaced. Background technique [0002] The tire pressure monitoring system has entered the field of cars, and the technology is relatively mature, but it is less used in the field of trucks. The reason is that the trailers of trucks are replaced frequently, sometimes even several times a day, which leads to the monitoring of objects in the truck system. ——The frequent replacement of tires makes tire monitoring difficult. [0003] For this situation, most of the current methods are to install a receiver on the trailer to monitor the tires of the trailer, and install a receiver on the front of the vehicle to monitor the tires on the front of the vehicle. The data is transmitted to the display on the head of the vehicle for display. When the truck changes trailers, replace the connecting ...
