Engineering Contradiction Analysis
1Reliability
If all terminal devices transmit data to the system platform simultaneously, then complete data collection is achieved, but system performance degrades due to massive data transmission
Solution Approach 1:
The patent segments data into different priority levels (first priority data and second priority data) based on data types and terminal device types. This segmentation allows the system to handle critical data immediately while deferring non-critical data, thus maintaining system performance while ensuring complete data collection over time.
Solution Approach 2:
The patent implements periodic data transmission where terminal devices send data at different intervals based on data priority and type. High-priority data is transmitted immediately or frequently, while low-priority data is transmitted periodically or only when queried by the system platform, reducing overall transmission load while maintaining data completeness.
2Productivity
If data transmission priority is determined by data type and terminal type, then system performance is improved through selective processing, but data transmission complexity increases
Solution Approach 1:
The patent changes the parameter of data transmission by introducing priority levels and different transmission rules based on data type and terminal type. The system platform determines transmission priorities using predefined rules that consider data characteristics (e.g., alarm data vs. normal operation data) and terminal characteristics, simplifying the decision-making process while improving performance.
Solution Approach 2:
The patent applies different transmission qualities and rules to different data types and terminal types. Instead of a uniform transmission approach, the system tailors transmission behavior locally based on specific data characteristics and device characteristics, optimizing performance for each data category while managing overall complexity through standardized classification.
3Loss of energy
If low-priority data is transmitted only when queried, then data transmission volume is reduced, but data freshness may be compromised
Solution Approach 1:
The patent implements dynamic data transmission where the transmission behavior adapts based on system conditions and data characteristics. For low-priority data, the system uses query-based transmission to reduce volume, but maintains the capability to switch to active transmission when the data becomes critical or the system queries for updates, thus balancing transmission volume reduction with data freshness maintenance.

AI summary
Embodiments of the present invention provide a data transmission method, apparatus, and system. The method is applied to a data transmission system. The data transmission system includes a system platform and a terminal device. A method performed by the system platform includes: determining, based on a type of the terminal device and a type of data generated by the terminal device, a data transmission rule of the data generated by the terminal device; and sending a data transmission message to the terminal device, where the data transmission message carries the data transmission rule, so that the terminal device sends, to the system platform based on the data transmission rule, the data corresponding to the data transmission rule. Massive data can be effectively prevented from being transmitted to the system platform by configuring the data transmission rule, and data with a high priority can be preferentially processed, to improve system performance.
