Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control and monitoring signal transmission systems are restricted by the number of clocks of the transmission clock signal, leading to reduced response speed when there is a difference between the number of control and monitoring data ranges, necessitating an inefficient use of frames.
Innovation Solution
A control and monitoring signal transmission system that time-divides data pulses into multiple ranges, including a changeable range that can be used for both data transmission from the master station and remote stations, allowing flexible allocation of data ranges without being restricted by the number of clocks, thereby optimizing data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of clocks of the transmission clock signal is increased to accommodate more data ranges, then the data transmission capacity is improved, but the frame becomes redundant and the response speed is reduced
Solution Approach 1:
The patent applies dynamics by making the data range allocation flexible and adaptable. The changeable range can be dynamically assigned to different remote stations based on actual transmission needs, allowing the system to optimize data ranges without increasing the number of clocks. This dynamic allocation resolves the contradiction by enabling efficient use of existing clock cycles.
Solution Approach 2:
The patent changes the parameter of data range allocation by introducing a changeable range that can be reassigned. Instead of fixing the number of data ranges to match the number of clocks, the system allows parameter changes in which remote station occupies which data range, thereby accommodating varying data requirements without increasing clock frequency.
2Device complexity
If the number of clocks of the transmission clock signal is restricted to maintain synchronization, then the system complexity is reduced, but the adaptability to different data range requirements is worsened
Solution Approach 1:
The patent applies universality by creating a changeable range that can serve multiple purposes. This single data range can be assigned to different remote stations for different transmission directions (master to remote or remote to master), making the system adaptable to various data range requirements without increasing clock complexity.
Solution Approach 2:
The system uses dynamic data range allocation where the changeable range can be reassigned based on actual transmission needs. This dynamic mechanism provides adaptability while maintaining simple synchronization, resolving the contradiction between system complexity and adaptability.
3Device complexity
If a fixed data range allocation is used for master station and remote stations, then the synchronization is simplified, but the flexibility to handle different data transmission requirements is reduced
Solution Approach 1:
The patent introduces dynamic data range allocation where the changeable range can be assigned to different remote stations based on actual transmission requirements. This dynamic approach maintains simple synchronization mechanisms while providing flexibility to handle various data transmission scenarios.
Solution Approach 2:
The system allows parameter changes in data range assignment without changing the fundamental synchronization protocol. The changeable range can be reassigned to accommodate different master-to-remote or remote-to-master transmission needs, maintaining synchronization simplicity while enhancing flexibility.

AI summary
A master station that transmits and receives data to and from a control part, and a plurality of remote stations that transmit and receive data to and from the master station by a transmission synchronization method via a common transmission line are comprised. Transmitting and receiving data between the master station and the remote stations is performed by superimposing data on a frame repeatedly transmitted from the master station. A transmission clock signal for synchronizing the master station and the remote station is composed of a plurality of clock pulses, each of the clock pulses has a data pulse used for data transmission of the master station and the remote station, the data pulse is allocated to each of the remote stations, for each of the remote stations, a numerical value as an address for obtaining the timing of the data pulse allocated to the own station is set. The data pulse is time-divided into a plurality of ranges, and at least one of the ranges is a changeable range that can be used for both data transmission from the master station and data transmission from the remote station.
