Laser Device Remote Control Authentication via Unique Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In construction settings, remotely controllable laser devices often face issues where multiple trades inadvertently change the operating parameters of each other's laser levels, leading to operational inefficiencies and the need for physical access to reprogram devices during faults, shifts, or power changes.
Innovation Solution
The implementation of a dual-mode system in laser devices and remote control units, where the laser device can operate in public mode for universal command reception and private mode for secure operation with a unique identifier, preventing unauthorized control from other units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser levels are remotely operated to save time during layout, then productivity is improved, but multiple trades can inadvertently change each other's operating parameters causing operational interference
Solution Approach 1:
A unique identifier code is introduced as an intermediary element in the command signal transmission. The remote control unit appends its unique identifier to each command signal, and the laser level verifies this identifier before executing commands. This intermediary mechanism prevents unauthorized control while maintaining remote operation capability, thus resolving the contradiction between productivity improvement and operational interference prevention.
2Ease of operation
If laser levels can be positioned remotely at significant distance, then ease of operation is improved, but physical access is required for reprogramming or fault handling increasing loss of time
Solution Approach 1:
The laser level is equipped with self-diagnostic capabilities and can be reprogrammed remotely through authenticated command signals. When a fault occurs or reprogramming is needed, the authorized remote control unit can send commands with its unique identifier to diagnose and resolve issues without requiring physical access. This self-service capability eliminates the time loss associated with physical access while maintaining the ease of remote positioning.
3Ease of operation
If remote control units can operate laser levels without authentication, then ease of operation is improved, but reliability deteriorates due to unauthorized control
Solution Approach 1:
A unique identifier verification mechanism is introduced as an intermediary step in the control process. The remote control unit appends its unique identifier to each command signal, and the laser level verifies this identifier against authorized codes before executing commands. This authentication mechanism ensures that only authorized remote control units can operate the laser level, maintaining reliability while preserving ease of operation for authorized users.

AI summary
A laser device operating system includes a laser device generating a laser beam when receiving a remote control unit command signal. The remote control unit operates in a public or private mode. In public mode the remote control unit generates a command signal transmitted to the laser device. In private mode the remote control unit generates a unique identifier prepended to the command signal. The laser device operates in a laser device public or private mode. In public mode the laser device responds to the remote control unit command signal or the command signal if transmitted by a second remote control unit. In private mode the laser device operates only upon receipt of the command signal and unique identifier, preventing laser device operation by the second remote control unit if the second unit does not include the unique identifier with the command signal.
