Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power system access networks face inflexibility and high construction costs due to the need for numerous base stations to support a large number of fixed smart meters and power distribution facilities, as existing mobile communications networks are not optimized for the power system's communication requirements.
Innovation Solution
An information transmission system that uses a wide area network to process and transmit report messages from system terminals to a power system control center, reducing the load on the network and allowing for fewer network devices, such as base stations, by using different network protocols for communication between terminals and the control center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large number of base stations are deployed to support numerous smart meters and power distribution facilities, then communication coverage and capacity are improved, but network construction costs and device complexity increase significantly
Solution Approach 1:
The patent applies universality by enabling base stations to serve dual purposes: traditional mobile communication functions and power system data collection functions. The base station is configured to receive both uplink data from smart meters/power distribution facilities and conventional mobile communication signals, eliminating the need for separate dedicated communication infrastructure for power system terminals.
Solution Approach 2:
The patent merges the power system access network with the existing mobile communication network infrastructure. By combining data transmission and control signaling for power system terminals with standard mobile communication traffic through the same base station, the solution reduces overall network complexity and construction costs while maintaining adequate communication capacity.
2Reliability
If the existing mobile communications network architecture is used to connect smart meters and power distribution facilities, then communication requirements are met, but networking flexibility is insufficient and construction costs are high
Solution Approach 1:
The patent applies local quality by implementing protocol conversion and specialized data handling specifically at the base station level for power system terminals, while maintaining standard mobile communication protocols for other users. This localized adaptation allows the network to meet power system-specific requirements without modifying the entire mobile communication infrastructure, thereby improving flexibility while maintaining reliability.
3Adaptability or versatility
If protocol conversion is implemented at the base station to handle different network transmission protocols, then communication compatibility between terminals and control center is improved, but base station processing complexity increases
Solution Approach 1:
The base station serves as an intermediary device between power system terminals using first network transmission protocols and the power system control center using second network transmission protocols. The base station performs protocol conversion, receiving data from terminals in the first protocol format and transmitting converted data to the control center in the second protocol format, thereby ensuring compatibility without requiring complex modifications at terminal or control center levels.

AI summary
An information transmission system and an information transmission method in the information transmission system are provided. The information transmission system includes: a power system control center (110), a network device (120), a transmission device (130), and at least one system terminal (140). The network device (120) belongs to a wide area network. Some or all system terminals (140) of the at least one system terminal (140) are configured to send at least one first report message to the transmission device (130), where the at least one first report message is transmitted by using a first network transmission protocol. The transmission device (130) is configured to send at least one second report message to the power system control center (110) by using the network device (120) based on information in the at least one first report message, where the at least one second report message is transmitted by using a second network transmission protocol that is different from the first network protocol. The information transmission system can increase a network throughput, reduce network construction costs, and better meet communication requirements of a power system.
