Tire Pressure Sensor Burning Device Joint Code Batch Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for burning communication protocols into tire pressure sensors are time-consuming due to a confirmation mechanism that checks for correct transmission to each sensor individually, which is unnecessary when the same protocol is to be applied to multiple sensors, leading to inefficiency.
Innovation Solution
A tire pressure sensor burning device and method that uses a joint code to switch all sensors to a common mode, allowing for simultaneous burning of the communication protocol without the need for individual confirmation, using a burning tool with a transmitting unit to send switch and burning commands to the sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a confirmation mechanism is used to check packet transmission for each tire pressure sensor individually, then transmission accuracy is improved, but burning time increases significantly
Solution Approach 1:
The patent merges multiple individual confirmation operations into a single batch operation. Instead of sending and confirming packets one by one for each sensor, the system sends a single packet containing multiple communication protocols to multiple sensors simultaneously, and receives a single response packet confirming all transmissions. This combining approach maintains transmission accuracy while dramatically reducing the number of communication rounds from N (for N sensors) to just 1.
Solution Approach 2:
The patent uses packet copying to create multiple copies of communication protocols within a single transmission packet. Each protocol is copied and placed in a specific position within the packet according to its assigned sensor, allowing multiple sensors to receive their respective protocols in one go. The response mechanism similarly copies confirmation data for all sensors into a single response packet, eliminating the need for individual confirmations.
2Reliability
If individual sequential burning is performed for each tire pressure sensor, then transmission reliability is improved, but productivity decreases
Solution Approach 1:
The patent combines multiple sequential burning operations into a single parallel operation. By merging the transmission of multiple protocols into one packet and the confirmation of multiple sensors into one response, the system achieves both high reliability (through confirmation) and high productivity (through parallel processing in a single communication round).
Solution Approach 2:
The patent performs preliminary organization of communication protocols into a batch packet before transmission. The burning device pre-arranges multiple protocols in a single packet with proper positioning for each sensor, and pre-prepares the response packet structure to receive confirmations from all sensors simultaneously. This preliminary preparation enables efficient batch processing while maintaining reliability.
3Reliability
If confirmation packets are sent for each sensor, then correct reception is verified, but device complexity increases
Solution Approach 1:
The patent uses a standardized packet copying template that can handle multiple sensors simultaneously. The transmission packet structure is copied and adapted for batch operations, with each protocol placed in a predetermined position. The response packet similarly uses a copied template structure to confirm reception status for all sensors in one go, reducing the complexity of managing individual confirmation protocols for each sensor.

AI summary
The present disclosure discloses a tire pressure sensor burning device for burning at least one tire pressure sensor having or being externally inputted an exclusive code and a joint code. The tire pressure sensor burning device includes a burning tool in which a communication protocol is stored, and the burning tool includes a transmitting unit connected with the tire pressure sensor and sending a switch command thereto for switching the mode of the tire pressure sensor from the exclusive code to the joint code. The burning tool sends a burning command to the tire pressure sensor with the transmitting unit, and unilaterally burns the communication protocol into the tire pressure sensor via the joint code.
