Restricted-Area Entry Control Using Transmitter Presence Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety control systems for monitoring collisions between robots and staff in restricted areas do not ensure that all staff members are carrying a transmitting unit, leading to potential safety risks.
Innovation Solution
A system comprising a first device for determining the presence of a staff member, a second device for controlling entry, and at least one sensing device for detecting an activated transmitting unit, ensuring only staff members with the unit can enter the area, using a revolving door and pressure-sensitive mat to manage entry and detect the number of staff, and a control device to allow entry when both conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detection methods are used to verify staff presence, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The system merges two different detection approaches: the first device detects staff presence through physical entry mechanisms (revolving door or pressure-sensitive mat), while the sensing device detects the transmitting unit through electromagnetic signals. By combining these two independent detection methods, the system achieves higher measurement precision for staff presence verification.
Solution Approach 2:
The control device serves multiple functions: it processes signals from the first device (entry detection), signals from the sensing device (transmitting unit detection), and makes the final authorization decision. This multi-functional design consolidates complexity into a single control unit rather than requiring separate systems for each function.

Function Achieved in This Case
This solution ensures that all staff entering the restricted area are carrying an activated transmitting unit, thereby enhancing safety by preventing unauthorized access and ensuring accurate position tracking.
Implementation Method 1
at least one sensing device, for detecting whether an activated transmitting unit, required to be carried by a staff member entering the designated area, is present in the target area
Implementation Method 2
the fourth device is a pressure-sensitive mat

AI summary
The present invention relates to a system, apparatus and method for safety control, the system comprising: a first device, which provides information capable of being used to determine whether a single staff member is present in a target area; a second device, which may be arranged at an entrance of a designated area, and used for controlling the entry of staff into the designated area; at least one sensing device, for detecting whether an activated transmitting unit, required to be carried by a staff member entering the designated area, is present in the target area; and a control device, for causing the second device to allow a staff member located in the target area to enter the designated area, when it is determined that a single staff member is present in the target area on the basis of the information from the first device and it is determined using the at least one sensing device that the activated transmitting unit is present in the target area. The system, apparatus and method can increase the safety of staff.
