Access Control Provisioning via Relay Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems require manual configuration of access control boards, which becomes complex as the number of terminals and devices increases, and poses challenges when replacing access control boards without access to the original software that identifies device-terminal relationships.
Innovation Solution
A system that automates the identification and configuration of access control devices by cycling through relays to determine associations between peripherals and wiring terminals, allowing for semi-automated configuration of new access control boards and maintenance of existing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of access control boards is used, then device-terminal relationships can be configured, but the complexity increases as the number of terminals and devices increases
Solution Approach 1:
The access control board automatically identifies and configures device-terminal relationships by cycling through relays and detecting which devices respond to control signals. The system performs self-provisioning without requiring manual configuration, thereby reducing configuration complexity while maintaining accuracy
Solution Approach 2:
The system uses feedback from device responses to relay control signals to automatically determine which terminal corresponds to which device. By monitoring which devices activate or respond to relay cycling, the system automatically maps device-terminal relationships, reducing manual configuration complexity
2Reliability
If manual configuration is used for replacing access control boards, then device-terminal relationships can be established, but time is lost and errors may occur
Solution Approach 1:
The access control board automatically provisions itself by cycling through relays and detecting device responses, eliminating the need for manual configuration during board replacement. This self-configuration capability dramatically reduces installation time while maintaining configuration accuracy
Solution Approach 2:
The system performs automatic device identification and terminal mapping as a preliminary step during board installation, before any manual configuration would be needed. This preliminary automatic configuration eliminates subsequent manual work and reduces overall installation time
3Productivity
If automated relay cycling is performed to identify device-terminal relationships, then configuration time is reduced, but the number of operations increases
Solution Approach 1:
The access control board automatically performs relay cycling and device detection without requiring external intervention. The system self-provisions by autonomously cycling through relays, sending control signals, and identifying which devices respond, thereby increasing configuration speed while the automation masks the operational complexity
4Measurement precision
If the system cycles through all relays to determine correspondence, then accurate device-terminal mapping is achieved, but energy consumption increases
Solution Approach 1:
The system cycles through relays in sequence and stops when the correct device-terminal correspondence is identified, rather than unnecessarily continuing through all relays. This partial action approach achieves accurate mapping while reducing energy consumption by eliminating redundant relay cycling
Solution Approach 2:
The system uses feedback from device responses during relay cycling to determine when the correct correspondence has been found. When a device responds to a relay control signal, the system identifies the mapping and can terminate the cycling process, achieving accurate mapping with minimal energy consumption

AI summary
Method, systems, devices, and techniques for access control provisioning are described. A monitoring system configured to monitor a property includes an access control device that is configured to receive an access control request and provide access to a portion of the property in response to the request. The system also includes a control unit or board that is configured to transmit, through a particular relay out of multiple relays, the access control request. The control unit further receives data indicating that the access control device received the access control request and determines that the particular relay corresponds to the access control device.
