Host-Slave Control System Remote Addressing Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current host-slave control systems, such as DALI, face inefficiencies in addressing and installation due to the need for manual input of identification codes and potential confusion in absolute positions, leading to errors and reduced installation efficiency, especially with a large number of slave devices.
Innovation Solution
A remote control-based host-slave control system where slave devices send addressing information including identification codes to a host device, which assigns addresses and sets positions, reducing human error and allowing for remote control of slave devices, and incorporating a status sensing module for dynamic environmental adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input of identification codes is used for addressing slave devices, then the host device can assign addresses to slave devices, but engineering staff often confuse absolute positions with actual construction positions, leading to installation errors
Solution Approach 1:
The patent replaces the manual mechanical input method (engineering staff physically inputting identification codes) with an automated optical/electronic system. The remote control device automatically detects and transmits identification codes to the host device, eliminating the need for manual input and reducing positioning errors during installation.
2Productivity
If addressing is performed before installation, then the host device can control slave devices individually, but installation efficiency is reduced due to the need to input identification codes one by one
Solution Approach 1:
The patent enables preliminary action by allowing the remote control device to automatically capture and transmit identification codes before installation is complete. This preliminary automatic addressing action eliminates the time-consuming manual input process and allows installation to proceed more efficiently without sacrificing addressing accuracy.
Solution Approach 2:
The remote control device serves as an intermediary between the slave devices and the host device. It automatically detects identification codes from slave devices and transmits them to the host device, streamlining the addressing process and significantly reducing the time required compared to manual input methods.
3Adaptability or versatility
If a large number of slave devices are installed, then the system can provide comprehensive control, but the probability of confusion between absolute positions and construction positions increases
Solution Approach 1:
The patent replaces manual input methods with automated detection and transmission of identification codes. This substitution eliminates human error in position matching, ensuring high reliability even when a large number of slave devices are installed across multiple locations.
Solution Approach 2:
The system implements feedback by having slave devices transmit their identification codes automatically to the host device through the remote control device. This feedback mechanism ensures that each slave device is correctly identified and associated with its actual construction position, maintaining high position matching accuracy regardless of system size.

AI summary
A host-slave control system and an addressing method thereof are provided. The host-slave control system includes a plurality of slave devices, a host device, and a remote control device. The host device is coupled to and controls the slave devices through a host-slave transmission interface. When one of the slave devices receives an addressing signal sent by the remote control device, the one of the slave devices sends an addressing information to the host device, such that the host device assigns a specific address as the address of the one of the slave devices according to the addressing information. In particular, the addressing information includes a default identification code of the one of the slave devices, and the address assigned to the one of the slave devices corresponds to the default identification code of the one of the slave devices.
