Engineering Contradiction Analysis
1Ease of manufacture
If non-original tire pressure sensors are used, then maintenance costs are reduced, but compatibility with vehicle-mounted tire pressure monitoring modules is lost
Solution Approach 1:
The patent changes the communication parameters of the non-original tire pressure sensor to match the vehicle's monitoring module. Specifically, it adjusts the wake-up period, data transmission frequency, and communication protocol parameters to be compatible with the original factory system, enabling cost-effective non-original sensors to work with various vehicle types.
Solution Approach 2:
The patent creates a universal communication adaptation mechanism that enables non-original tire pressure sensors to be compatible with multiple different vehicle types and monitoring modules. By implementing state-machine-based communication protocols and parameter adjustments, a single non-original sensor can adapt to work with various vehicle systems.
2Productivity
If tire pressure sensor wakes up frequently to transmit data, then data transmission frequency is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic wake-up mechanisms where the tire pressure sensor wakes up at predetermined intervals to collect and transmit data, then returns to sleep mode. The wake-up period and data transmission frequency are dynamically adjusted based on vehicle state (parking, driving, acceleration, deceleration), ensuring data is transmitted frequently enough for safety while minimizing power consumption during idle periods.
Solution Approach 2:
The patent dynamically adjusts the wake-up period and data transmission frequency based on real-time vehicle conditions. During normal driving, data is transmitted at standard intervals; during acceleration or deceleration, transmission frequency increases to provide timely safety information. This dynamic adjustment optimizes both data transmission effectiveness and power consumption.

AI summary
The application discloses a tire pressure sensor communication method, device, electronic equipment and storage medium. The method comprises the follow steps: acquiring a first tire state when a tire pressure sensor is awakened; collecting first tire pressure data corresponding to the first tire state, and determining whether the first tire state meets a preset state switching condition according to the first tire pressure data; controlling the first tire state to switch to a corresponding second tire state if the first tire state meets the state switching condition; acquiring a preset tire pressure data transmission control parameter corresponding to the second tire state; collecting second tire pressure data corresponding to the second tire state according to the tire pressure data transmission control parameter, and sending the second tire pressure data to a vehicle-mounted tire pressure monitoring module.
