Network Security System Transfer Devices for Field Bus Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional security systems using dedicated hard-wired field busses for connecting devices are time-consuming and expensive to install, and converting devices to network compatibility can be costly and render non-networked devices incompatible.
Innovation Solution
A system that utilizes an existing network to connect discrete parts of a security system by employing transfer devices to convert and packetize data between dedicated hard-wired field busses and the network, allowing for versatile and cost-effective connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated hard-wired field busses are installed to connect each device in the security system, then reliable device connectivity is achieved, but installation time and cost increase significantly
Solution Approach 1:
The patent introduces transfer devices as intermediaries that convert data between field bus protocols and network protocols. These transfer devices enable existing field bus connected devices to communicate over standard networks without requiring physical re-wiring, thus maintaining reliable connectivity while dramatically reducing installation time and cost.
Solution Approach 2:
The patent replaces the mechanical field bus wiring system with an electronic/network-based communication system. Instead of physically connecting each device through dedicated field bus cables, the system uses standard network infrastructure with protocol conversion, substituting a complex mechanical wiring system with a more flexible electronic communication approach.
2Adaptability or versatility
If each device is converted or replaced to enable network connection, then network-based connectivity is achieved, but cost increases and compatibility with existing non-networked devices is lost
Solution Approach 1:
The transfer devices serve as intermediaries between networked and non-networked devices. They receive data from field bus connected devices, convert it to network protocols for transmission over the network, and vice versa. This allows the system to support both network-capable and traditional field bus devices simultaneously, maintaining compatibility while enabling network connectivity.
Solution Approach 2:
The transfer devices provide multi-functionality by supporting multiple communication protocols (field bus and network protocols) simultaneously. A single transfer device can interface with various types of devices using different protocols, making the system universally compatible without requiring device replacement or conversion.

AI summary
A system and method for connecting a security system using a network. The security system includes at least two discrete parts and is connected using a local area network. The security system also includes a first dedicated, hard-wired field bus, a first plurality of peripheral devices, a control panel, a first transfer device, a second transfer device, a second dedicated, hard-wired field bus, and a second plurality of peripheral devices. The control panel is configured to send data through the first field bus. Each of the first plurality of peripheral devices is coupled to the first field bus and is configured to receive the data from the control panel. The first transfer device is connected to the control panel and is configured to packetize the data from the control panel and send the packetized data through the local area network. The second transfer device is coupled to the second field bus and is configured to receive the packetized data from the first transfer device and depacketize the packetized data. Each of the second plurality of peripheral devices is coupled to the second field bus and is configured to receive the data from the second transfer device.
