Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote signal transmission devices face issues with signal attenuation and noise jamming due to increased resistance and input load impedance when multiple sub-machines are connected in parallel, leading to inefficient signal transmission and distortion.
Innovation Solution
A remote antijamming transmission device that uses a signal current as a transmission medium, allowing sub-machines to be connected in series without load effects, with a host and sub-machine configuration including CPUs, signal processing units, and transmission units, and employing a signal current transmission line for non-contact signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If multiple sub-machines are connected in parallel to the host, then the signal transmission distance is extended, but the signal voltage is attenuated due to increased resistance and decreased input load impedance
Solution Approach 1:
The patent replaces the conventional voltage-based signal transmission with a current-based signal transmission system. The host outputs a current signal that flows through the signal transmission line to multiple sub-machines connected in parallel. This substitution of transmission medium (from voltage to current) resolves the contradiction because current signals are less affected by line resistance and load impedance variations, thereby maintaining signal stability over extended transmission distances while supporting multiple parallel connections.
2Reliability
If repeaters with amplifiers are arranged at intervals in the signal transmission line, then the attenuated signal is amplified, but the noise is also amplified and transmission speed is significantly reduced
Solution Approach 1:
The patent extracts and eliminates the need for repeaters and amplifiers from the signal transmission system by adopting current signal transmission. Since current signals maintain their strength over long distances without significant attenuation, the intermediate amplification devices are rendered unnecessary. This removal of amplifiers prevents noise amplification and avoids the transmission speed reductions associated with repeated signal regeneration, thereby resolving the contradiction between signal strength maintenance and transmission speed.
3Productivity
If voltage is used as the signal transmission medium, then the signal can be transmitted, but interference voltage is applied to the signal voltage causing distortion
Solution Approach 1:
The patent changes the fundamental parameter of signal transmission from voltage to current. By using current as the transmission medium instead of voltage, the system becomes inherently more resistant to interference voltage. Current signals are less susceptible to electromagnetic interference and noise injection that typically affect voltage-based systems. This parameter change resolves the contradiction by maintaining high transmission efficiency while significantly reducing the impact of interference voltage on the signal.

AI summary
A remote antijamming transmission device and method for the same is provided. A signal current transmission line is between the host and the sub-machine arranged along a path of signal current transmission line and kept at a distance from the signal current transmission line. The sub-machine comprises a signal sensor component. The interval is a range where the signal sensor component may sense a signal current transmitted by the host connected to the sub-machine in a non-contact manner. Thus, no load effect is caused. The signal current transmitted by the host is not attenuated due to current bypass, so the effect of remote transmission is achieved. The transmission current in the signal current transmission line does not make the transmission signal to be attenuated even if the amount of sub-machines increases and then the current is divided. Unlimited amounts of sub-machines may be arranged near the signal current transmission line.
