Radio Frequency Host Protection for Abnormal Energy Output

Solution Overview

Problem

Existing methods for protecting against radio frequency operation abnormalities are inadequate, leading to potential damage to the radio frequency host and operated objects due to continuous output of radio frequency energy without effective intervention.

Innovation Solution

A dual protection mechanism involving real-time detection of preset kinds of detection data, stopping radio frequency energy output, and cutting off the energy path using a radio frequency generating apparatus and an emergency stop apparatus when abnormal states are detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If only alarm prompt is used for abnormal radio frequency operation, then the system structure remains simple, but the protection effectiveness is insufficient

Engineering Contradiction:

Improveprotection effectivenessVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protection system is segmented into multiple independent protective measures: alarm prompt mechanism, automatic output stopping mechanism, and emergency stop mechanism. Each segment operates independently to provide layered protection, ensuring that if one mechanism fails, others remain functional to prevent damage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements beforehand cushioning by pre-configuring multiple protective mechanisms that activate in sequence. The alarm prompt serves as the first line of defense, followed by automatic output stopping, and finally the emergency stop mechanism as a last resort, creating a cushioned protection hierarchy against potential abnormalities.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If alarm prompt is given for abnormal operation, then the operator can be alerted, but the operator may not notice the prompt in time causing damage

Engineering Contradiction:

Improveprotection success rateVSAvoidresponse time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system implements automatic feedback mechanisms where the detection apparatus continuously monitors radio frequency operation parameters and automatically triggers protective actions when abnormalities are detected. This closed-loop feedback eliminates dependency on operator attention and response time, ensuring immediate protective action.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The protection system performs self-service by automatically detecting abnormalities and executing protective measures without requiring operator intervention. The system monitors itself and autonomously activates the appropriate protective mechanism, freeing it from reliance on human response.

Inventive Principle:

Principle #25Self-service

3Reliability

If multiple protective measures are implemented simultaneously, then the protection success rate is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

The protection system is segmented into multiple independent protective measures: alarm prompt mechanism, automatic output stopping mechanism, and emergency stop mechanism. Each segment operates independently to provide layered protection, ensuring that if one mechanism fails, others remain functional to prevent damage.

AI summary

Disclosed are a protection method for radio frequency operation abnormality, a radio frequency host, and a radio frequency operation system. The protection method for radio frequency operation abnormality includes: detecting preset kinds of detection data of a radio frequency operation in real time when detecting that a radio frequency host continuously outputs radio frequency energy; determining whether detected preset kinds of detection data meets a preset abnormal state; and when the preset abnormal state is met, controlling a radio frequency generating apparatus to stop outputting radio frequency energy and controlling an emergency stop apparatus to cut off a radio frequency energy output path of the radio frequency host. By means of dual protection for operation abnormality, safety of radio frequency operation is improved.
