Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems in large spaces, such as theaters, face challenges in simultaneous control of tens to hundreds of thousands of devices without temporal delays, requiring efficient communication and data transmission techniques to prevent disconnection and delay issues.
Innovation Solution
A lighting device configuration that includes a storage unit for scenarios, a communication unit for receiving control messages via RF protocols like Bluetooth or ZigBee, and a control unit for activating scenarios based on pre-stored information, utilizing a push service like MQTT for reliable and timely control message delivery, ensuring synchronized operation across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large number of lighting devices are controlled simultaneously in a large space, then the lighting coverage and control capability are improved, but communication disconnection and temporal delays occur
Solution Approach 1:
The system segments the control architecture into multiple layers: push server for message queuing, control devices for scenario management, and lighting devices for execution. This segmentation distributes the control load across multiple nodes, preventing communication bottlenecks and disconnections when controlling tens to hundreds of thousands of lighting devices simultaneously.
Solution Approach 2:
The patent implements pre-processing by storing control messages and scenario data in advance on the push server and control devices. Messages are queued and prepared before being transmitted to lighting devices, ensuring that control information is ready for immediate delivery without temporal delays even when controlling a large number of devices.
2Quantity of substance
If control messages are transmitted to tens to hundreds of thousands of lighting devices simultaneously, then the lighting coverage is improved, but temporal delays occur
Solution Approach 1:
The system performs preliminary actions by pre-storing control messages and scenario configurations on the push server and control devices before actual execution. This advance preparation ensures that when control commands need to be sent to tens of thousands of lighting devices simultaneously, the messages are already queued and ready for immediate transmission without temporal delays.
Solution Approach 2:
The patent introduces intermediary components (push server and control devices) that act as buffers between the control system and lighting devices. These intermediaries pre-process and queue control messages, enabling simultaneous transmission to a large number of devices without causing temporal delays in message delivery.
3Reliability
If a push service is used for control message transmission, then the control reliability is improved, but the system complexity increases
Solution Approach 1:
The patent introduces a push server as an intermediary component that implements the push service for control message transmission. While this adds a system component, it centralizes the message queuing and distribution logic, which actually simplifies the overall system architecture by providing a single point of control for reliable message delivery to all lighting devices.
Solution Approach 2:
The push server and control devices are designed with multi-functionality, handling message queuing, scenario management, and device control in a single integrated platform. This universal design reduces the need for separate specialized components, thereby managing system complexity while maintaining high control reliability through the push service mechanism.
