Program Update Confirmation Mode for Elevator Information Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing devices require extensive confirmation processing after program updates, leading to prolonged downtime and delayed restarts due to the need to verify the normal operation of multiple programs across processors.
Innovation Solution
The implementation of an update confirmation mode in the information processing device, where processors are reset and started in this mode to monitor the normal operation of updated programs, allowing for quicker confirmation and reduced downtime by generating monitoring process start completion signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional confirmation processing is performed on the whole of each program to verify normal update, then update reliability is ensured, but confirmation time increases and device restart is delayed
Solution Approach 1:
The patent extracts the essential confirmation function from comprehensive program verification. Instead of confirming the entire program, it only confirms whether a monitoring process was normally generated, separating the critical verification step from the optional comprehensive testing step.
Solution Approach 2:
The confirmation process is segmented into two levels: a quick confirmation level that checks only the monitoring process generation, and an optional detailed confirmation level for comprehensive program verification. This segmentation allows flexible trade-off between speed and thoroughness.
2Reliability
If comprehensive program verification is performed after update, then update correctness is confirmed, but device downtime increases
Solution Approach 1:
The patent applies partial action by performing only the necessary minimum verification (monitoring process generation check) rather than complete program verification. This partial confirmation is sufficient to ensure basic update correctness while minimizing downtime.
Solution Approach 2:
The monitoring process generation is verified immediately after program update before full system operation resumes. This preliminary confirmation ensures update correctness is established early, allowing faster system recovery.
3Stability of the object's composition
If full program confirmation is executed to ensure normal operation, then system stability is improved, but restart speed decreases
Solution Approach 1:
The patent extracts the essential stability-ensuring function to only the monitoring process generation check. This extracted confirmation method maintains system stability by verifying critical processes while eliminating time-consuming comprehensive checks.
Solution Approach 2:
The confirmation scope parameter is changed from comprehensive program verification to selective monitoring process verification. This parameter change maintains essential stability checks while enabling faster restart.
Data Source
AI summary
An information processing device includes: a memory that stores therein a main program; a processor that reads out and executes the main program stored in the memory; a program update unit that updates the main program stored in the memory; and a start control unit that starts the processor in an update confirmation mode when the processor is reset after the main program stored in the memory is updated by the program update unit. The processor, when being started in the update confirmation mode, generates a monitoring process that monitors whether a process generated by the execution of the main program is normally operated, and outputs a monitoring process start completion signal when the monitoring process has been normally generated. The information processing device can reduce time required for processing of confirming whether each program have been normally updated after the update of the programs.
