This application relates to a wireless signal optimization method for tire pressure information data transmission, comprising the following steps: a sensor node initiates a relay transmission mode based on link quality judgment, selects a relay node through a micro-routing protocol, and forwards data packets to a distributed slot antenna formed by coupling through vehicle body gaps via neighboring nodes; a central signal aggregator fuses the data received from multiple paths to reconstruct the complete tire pressure data stream. This application achieves reliable and continuous transmission of tire pressure signals under extreme obstruction environments, while also meeting the requirements of low power consumption and real-time performance.
