Factory Wireless Communication Switching for Speed and Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems in factories are not optimized for various types of data, leading to suboptimal transmission and reception, as they typically rely on fixed communication methods that do not suit the diverse characteristics of data being transmitted.
Innovation Solution
A wireless communication apparatus that selectively uses two wireless communication portions with different characteristics: one for high-speed and large-capacity communication, and another for more reliable communication, based on data size or type, with the ability to store data in memory for later transmission when a superior connection is established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed communication method is used in conventional systems, then the system structure is simple, but the communication suitability for various data types is poor
Solution Approach 1:
The system dynamically selects between two wireless communication portions (first and second) based on data characteristics such as data size and type. The controller determines which communication portion to use by evaluating whether the data exceeds a threshold size or matches specific types, enabling adaptive communication rather than a fixed method.
Solution Approach 2:
The communication system is divided into two distinct wireless communication portions: a first wireless communication portion for high-speed, large-capacity data transmission, and a second wireless communication portion for more reliable, lower-speed transmission. This segmentation allows each portion to be optimized for specific data types while maintaining overall system adaptability.
2Speed
If high-speed wireless communication is used for all data, then transmission speed is improved, but communication reliability deteriorates
Solution Approach 1:
Different communication portions are assigned different quality characteristics: the first wireless communication portion provides high-speed transmission for suitable data types, while the second wireless communication portion provides higher reliability for other data types. The controller selects the appropriate portion based on local data characteristics, ensuring each data packet receives the most suitable transmission quality.
3Area of stationary object
If multiple access points are deployed to improve coverage, then communication coverage is improved, but system complexity and cost increase
Solution Approach 1:
Each wireless communication apparatus is equipped with both first and second wireless communication portions, making it multi-functional. This allows a single apparatus to handle both high-speed and reliable communication modes, reducing the need for multiple specialized access points while maintaining comprehensive coverage and functionality.

AI summary
The present invention is directed to managing a process in a factory while employing a communication method suitable to various kinds of data that should be transmitted. A wireless communication apparatus configured to manage a process in a factory includes an interface connected to a device and usable to receive data from the device, a first wireless communication portion, a second wireless communication portion, and a controller configured to, to wirelessly transmit the data received via the interface, select one of the first wireless communication portion and the second wireless communication portion according to this data. The first wireless communication portion is configured to carry out communication at a higher speed and with a larger capacity than the second wireless communication portion. The second wireless communication portion is configured to carry out more reliable communication than the first wireless communication portion.
