Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless sensor devices lack the ability to be remotely programmed, limiting their flexibility and efficiency in controlling building systems, as they often require manual intervention for changes in behavior or settings, especially in power management modes.
Innovation Solution
A wireless sensor device equipped with a controller that can receive and execute messages from a remotely located device to switch between low-power sleep and high-power awake modes based on specified algorithms or parameter settings, allowing for remote programming and adaptive power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual programming intervention is required for wireless sensor devices, then device settings can be changed, but flexibility and efficiency in controlling building systems deteriorates due to lack of remote programming capability
Solution Approach 1:
A message queue mechanism serves as an intermediary between remote devices and the wireless sensor device. The message queue stores programming messages remotely, allowing the sensor device to retrieve and execute them without requiring manual intervention. This intermediary system enables flexible remote programming while maintaining ease of operation through automated message retrieval and execution.
2Adaptability or versatility
If wireless sensor device remains in awake mode for remote communication, then remote programming is enabled, but power consumption increases
Solution Approach 1:
The wireless sensor device operates in periodic cycles, switching between awake mode for remote communication and sleep mode for power conservation. The device wakes up at scheduled intervals to check for and execute programming messages from the remote message queue, then returns to sleep mode. This periodic operation enables remote programming capability while significantly reducing average power consumption compared to continuous awake operation.
3Device complexity
If sleep algorithm is fixed in wireless sensor device, then power management is simplified, but adaptability to different operational requirements deteriorates
Solution Approach 1:
The sleep algorithm transitions from a fixed configuration to a dynamic, remotely programmable system. Programming messages can modify sleep algorithm parameters such as wake intervals, sleep duration, and activation conditions based on operational requirements. This dynamic approach maintains relatively simple device architecture while significantly improving adaptability to different power management needs through remote configuration.

AI summary
The disclosure relates generally to wireless sensor devices, and more particularly, to remote programming of wireless sensor devices. A wireless sensor device wirelessly may receive messages from a remotely located device to a wireless sensor device. The wireless sensor device may be programmed via the receive messages. In one example, a building controller may be programmed to wirelessly send one or more messages to a wireless sensor device in order to change the behavior of the wireless sensor device, even while the wireless sensor device and building controller are on-line and actively controlling a building control system. In some instances, a technician or installer may use a diagnostic or setup tool to send one or more messages to a wireless sensor device to change the behavior of the wireless sensor device. These are just some examples.
