Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security inspection device management systems require numerous signal lines for remote control, leading to complex layouts, increased workload, and vulnerability to interference, making centralized management inefficient and unreliable.
Innovation Solution
Implementing a field bus network for bus communication between local security inspection devices and a remote control site, reducing the number of signal lines and simplifying layouts, while enabling accurate and reliable control and status monitoring through a remote control module and field bus branches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional signal line control is used for each local device, then control operations can be performed, but the number of signal lines becomes very large and layout becomes complicated
Solution Approach 1:
The patent merges multiple individual signal lines into a single bus structure. Instead of having separate signal lines for each local device's power-on/off and status signals, all devices are connected to a common bus that carries multiple signals simultaneously, dramatically reducing the number of physical lines required
Solution Approach 2:
The bus structure serves multiple functions: it carries power-on/off control signals, status feedback signals, and diagnostic information for multiple devices simultaneously. A single bus line replaces what would otherwise require numerous dedicated signal lines, making the system more versatile and easier to manage
2Reliability
If each signal occupies one signal line, then signal transmission is straightforward, but the number of signal lines increases and layout becomes complicated
Solution Approach 1:
Multiple signals are combined and transmitted through a shared bus structure. The bus allows simultaneous transmission of multiple signals (control and status) without requiring separate dedicated lines for each signal, reducing the overall complexity while maintaining transmission reliability through proper bus protocols
3Ease of operation
If numerous signal lines are used for long-distance transmission, then control signals can reach remote devices, but signals become vulnerable to interference and erroneous control status
Solution Approach 1:
By merging signals into a bus structure, the patent reduces the total number of signal lines requiring long-distance transmission. Fewer lines mean fewer potential points of interference. The bus structure also enables centralized management of signal integrity and error handling
4Ease of operation
If traditional signal line convergence is used, then power-on/off control can be achieved, but operator workload increases due to need to move to site
Solution Approach 1:
The bus structure acts as an intermediary that enables remote control operations. Through the bus network, operators can control local devices from a remote location without physically moving to each device site, saving time and reducing operational complexity
