Solution Overview
Problem
Construction machine operators face challenges in monitoring and controlling operating parameters while navigating a working trajectory, as they need to continuously check and adjust settings like milling depth, which can be time-consuming and demanding, especially when dealing with varying terrain and obstacles.
Innovation Solution
A method using sensor devices to detect marks placed along the working trajectory, which encode control commands for operating parameters, allowing the data processing device to generate and transmit control commands to the machine control unit, thereby relieving the operator from manual control of these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually monitors and controls operating parameters during construction machine operation, then the machine can respond to terrain variations and obstacles, but the operator workload increases and efficiency decreases
Solution Approach 1:
The construction machine automatically detects marks on the ground and generates control commands for operating parameters without operator intervention. The sensor device detects mark positions, the data processing device determines control commands, and the machine control executes them autonomously, allowing the machine to service itself during operation.
Solution Approach 2:
The manual mechanical control system operated by the operator is replaced with an automated electronic control system. The sensor device, data processing device, and machine control work together to substitute the operator's manual monitoring and adjustment actions with automated electronic detection and control.
2Manufacturing precision
If the operator continuously checks and adjusts operating parameters like milling depth, then control precision is maintained, but time is lost and operation becomes demanding
Solution Approach 1:
The sensor device continuously detects mark positions on the ground, providing feedback to the data processing device. This feedback loop enables real-time determination of appropriate control commands, maintaining control precision through continuous information about the machine's position relative to marked locations.
Solution Approach 2:
Marks are placed on the ground in advance to indicate desired operating parameters and positions. This preliminary marking allows the automated system to determine control commands without real-time operator decision-making, eliminating delays while maintaining precision.
3Adaptability or versatility
If manual control commands are entered via console, then flexibility in operation is maintained, but the complexity of the control system increases
Solution Approach 1:
The automated control system uses a universal approach where marks on the ground can specify various operating parameters (milling depth, working height, speed) and the same sensor and data processing devices handle all types of parameter adjustments, eliminating the need for separate control mechanisms for each function.

AI summary
The present invention relates to a method for controlling a construction machine which performs a working operation along a working trajectory on a ground depending on at least one operating parameter. A method according to the present invention comprises placing at least one mark, detectable by a sensor device, stationary on the ground in a region which, regarded from at least one position of the construction machine on the working trajectory, is located in the detection region of the sensor device. The mark is detected by the sensor device, resulting in the generation of sensor data which is processed by the data processing device of the construction machine. A control command is generated for the machine control of the construction machine for changing at least one operating parameter of the construction machine.
