Takeover system for an air conditioning apparatus to transmit information from a first board to a second board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for replacing a defective control board in an air conditioning apparatus require manual backup and transfer of information using a personal computer, which is time-consuming and labor-intensive.
Innovation Solution
An information takeover system that includes a first board with a control unit and storage unit, a second board connectable for information exchange, and a cable with specific connectors and terminals to automatically transmit and receive information between the boards, allowing seamless transfer of data without the need for external power sources or dedicated power supplies.

Engineering Contradiction Analysis
1Reliability
If manual backup and transfer of information using a personal computer is used, then information can be transferred between control boards, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
A cable with connectors is introduced as an intermediary device to directly connect the first control board and the second control board, enabling automatic information transfer without manual intervention or personal computers. The cable includes a first connector connecting to the first control board and a second connector connecting to the second control board, with terminals that automatically establish electrical connections for data transfer.
Solution Approach 2:
The control boards are designed to automatically perform information backup and transfer when connected via the cable. The first control board automatically backs up information to the cable's storage, and the second control board automatically receives and restores the information, eliminating the need for manual operations by technicians.
2Extent of automation
If a cable with connectors is used to connect control boards, then automatic information transfer is enabled, but voltage signal compatibility between different boards must be ensured
Solution Approach 1:
The terminal in the cable is designed to output different voltage signals corresponding to different logic levels (e.g., HIGH and LOW signals). The terminal can change its output voltage parameter based on the connection state, outputting a HIGH signal when connected to the first control board and a LOW signal when connected to the second control board, ensuring compatibility with different board voltage requirements.

AI summary
An information takeover system includes: a first board that includes a first control unit and a first storage unit storing first information about an air conditioning apparatus; and a second board that includes a second control unit and is connectable to the first board in an information exchangeable manner. The first control unit is configured to perform first control to transmit the first information to the second board with the first board and the second board connected to each other in the information exchangeable manner.
