Wireless Security Device Enrollment Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless security systems require extensive manual input and are prone to errors during the enrollment of wireless sensors, which is time-consuming and inefficient, especially when dealing with multiple devices.
Innovation Solution
A system and method that reduces manual intervention by using an enroll command to buffer serial numbers and unique identifiers from wireless devices, allowing for automated enrollment through a controller that receives and stores these identifiers and sends confirmation commands to stop unnecessary transmissions, minimizing errors and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of serial numbers is used for sensor enrollment, then the controller can store sensor information, but the process becomes time-consuming and error-prone
Solution Approach 1:
The wireless sensors automatically transmit their serial numbers to the controller during enrollment without requiring manual intervention to read and input serial numbers. The sensors perform self-identification and the controller automatically receives and stores the serial numbers, eliminating manual typing errors and saving time.
Solution Approach 2:
The manual mechanical process of reading serial numbers from physical plates and typing them into a keypad is replaced with an automated wireless communication system where sensors transmit their identifiers electronically to the controller, eliminating human error and improving efficiency.
2Ease of operation
If automated enrollment systems are used, then manual input is reduced, but the sensors must operate in unique manners or be passed close to the controller
Solution Approach 1:
The controller's enrollment function is designed to universally accept any wireless sensor that transmits its serial number automatically. The same enrollment mechanism works for all sensor types without requiring different operations, and the controller handles multiple sensors through a single standardized process rather than requiring unique sensor operations.
Solution Approach 2:
Sensors automatically transmit their serial numbers when powered on or activated, eliminating the need for manual intervention. The sensors perform self-identification and the controller automatically receives and stores the serial numbers, making the process simple and universal for all sensor types.
3Adaptability or versatility
If multiple wireless sensors are enrolled, then system coverage is improved, but the enrollment process becomes more cumbersome
Solution Approach 1:
The controller continuously receives serial numbers from multiple wireless sensors in sequence without interruption. The enrollment process flows continuously as each sensor automatically transmits its identifier and the controller stores it, allowing multiple sensors to be enrolled in a seamless, time-efficient manner without repeated manual operations.
Solution Approach 2:
Each wireless sensor automatically performs self-identification and transmission of its serial number to the controller. Multiple sensors can simultaneously or sequentially perform this self-enrollment operation, and the controller automatically stores all serial numbers without requiring repeated manual intervention for each sensor.

AI summary
A system and method are disclosed for enrolling wireless security system devices (alarms, detectors, lights) in a security system. A controller is provided and is capable of exchanging wireless signals with the devices. The system has an enroll mode where the wireless devices transmit enroll signals to the controller. The enroll signals contain an identifier associated with each device. An installer uses a keypad or other interface device to review each of the devices that have sent a signal, and to accept them for enrollment or ignore them. After review, the controller sends a signal to the devices instructing them to cease transmitting enroll signals to the controller. If the power of an enrolled device is cycled (battery replacement), another enroll command is sent to the controller. The controller determines whether the device was already enrolled, and if it has the controller sends a signal to the device to stop sending the enroll command.
