Remote Work Machine Startup With Object Detection Approval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines in cold regions require remote engine starting, but current systems lack safety measures to prevent engine startup when workers are present, risking accidents and reducing efficiency.
Innovation Solution
A work machine equipped with an object detection system and photo shooting device to assess the surroundings, allowing remote engine startup only when no workers are detected, and enabling remote video transmission for approval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote engine starting is implemented to allow operator to wait remotely during warm-up operation, then operator convenience and time savings are improved, but safety risks increase due to possibility of worker contact with moving parts
Solution Approach 1:
The object detection device performs preliminary detection of workers around the machine body before the engine starts. The controller uses this detection result to determine whether to permit remote starting, preventing harmful contact before it can occur.
Solution Approach 2:
The object detection device and controller act as intermediaries between the remote starting command and the actual engine startup. They mediate by detecting worker presence and controlling the starting permission based on safety conditions.
2Object-affected harmful factors
If engine starting is always prohibited when worker exists around machine body, then safety is improved, but work efficiency deteriorates due to unnecessary startup prohibitions
Solution Approach 1:
The system applies different starting permission decisions to different local situations. When workers are detected in dangerous zones, starting is prohibited. When no workers are detected or they are in safe zones, starting is permitted, optimizing efficiency for each specific situation.
Solution Approach 2:
The starting permission is dynamic rather than static. The controller continuously monitors object detection results and adjusts the starting permission state accordingly, allowing starting when safe and prohibiting when dangerous, rather than using a fixed prohibition rule.
3Reliability
If object detection device and photo shooting device are added to enable safe remote starting, then safety and efficiency are improved, but device complexity increases
Solution Approach 1:
The photo shooting device serves multiple functions: it captures images for safety assessment, provides visual records for approval documentation, and can potentially be used for other monitoring purposes. This multi-functionality justifies the added complexity by maximizing the utility of each added component.
Solution Approach 2:
The object detection device and photo shooting device provide feedback to the controller about the surrounding environment. This feedback loop enables intelligent decision-making regarding starting permission, improving reliability while keeping the control logic manageable through structured feedback processing.

AI summary
A work machine includes an object detection device, a photo shooting device, and a controller that controls starting of a prime mover. The controller determines whether or not an object exists around a machine body on the basis of a detection signal arising from detection by the object detection device. The controller starts the prime mover in a case in which a prime mover starting command has been acquired from an external information terminal and when it is determined that an object does not exist around the machine body. The controller transmits data of video shot by the photo shooting device and a starting approval request of the prime mover to the external information terminal without starting the prime mover in the case in which the prime mover starting command has been acquired from the external information terminal and when it is determined that an object exists around the machine body. The controller starts the prime mover when acquiring an approval command to the starting approval request of the prime mover from the external information terminal.
