Gaming Machine Backup Power for Abnormal Operation Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming machines installed in 24-hour facilities are vulnerable to tampering and dishonest acts, especially during power outages, as existing security measures require the main power supply to be ON for authentication and logging, making it difficult to detect and record abnormal operations when the power is OFF.
Innovation Solution
A gaming machine design incorporating a backup power supply system, including lithium batteries and electrolytic capacitors, that maintains operation and logs abnormal events even when the main power supply voltage falls below operational levels, allowing for secure storage and analysis of historical information in both internal and removable memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the main power supply is turned off to save energy or during power outages, then energy consumption is reduced, but the ability to detect and record abnormal operations is lost
Solution Approach 1:
The system performs preliminary actions by continuously monitoring abnormal operations and storing them in memory even when the main power supply is off. The controller detects abnormal operations and stores them in memory before power is needed, ensuring security data is preserved without requiring continuous power for active monitoring.
Solution Approach 2:
The system creates a copy of security-relevant data (abnormal operation records) in memory that can be retained without continuous power. By storing copies of abnormal operation information in non-volatile or preserved memory states, the system maintains security monitoring capability without requiring the main power supply to remain on.
2Reliability
If the main power supply is kept on continuously to maintain security monitoring, then abnormal operations can be detected and recorded, but energy consumption increases
Solution Approach 1:
The controller performs preliminary detection and storage of abnormal operations during periods when power is available, preparing security data in advance. This allows the system to have security monitoring capability ready without requiring continuous high-power operation, as the detection function can operate in a low-power or standby mode between abnormal events.
Solution Approach 2:
The system uses the controller's existing processing capabilities to detect and record abnormal operations without requiring separate dedicated monitoring hardware that would consume additional power. The controller serves multiple functions including security monitoring, reducing overall energy consumption while maintaining reliability.
3Measurement precision
If authentication requires the main power supply to be on, then proper authentication can be performed, but the system cannot authenticate or log events during power outages
Solution Approach 1:
The system performs preliminary storage of authentication-relevant data (abnormal operation records with identification information) in memory before authentication is needed. This allows the system to maintain authentication accuracy by having data ready, while also enabling operational flexibility during power outages since the data persists without continuous power.
Solution Approach 2:
The system creates and maintains copies of authentication-critical data in memory that can survive power cycles. By storing copies of abnormal operation records with associated identification information, the system ensures authentication accuracy is maintained while enabling the system to operate and log events during power outages.
4Loss of information
If detailed logging of abnormal operations is implemented, then security analysis capability is improved, but memory requirements and system complexity increase
Solution Approach 1:
The system extracts only the essential security-relevant information (abnormal operation details and associated identification information) and stores it in memory. By taking out only the necessary data elements needed for security analysis rather than logging all system operations, the system improves security information retention while avoiding excessive memory requirements and system complexity.

Implementation Method 1
a second power supply (a backup power supply 91 and gaming board backup power supply 73)... The first power supply supplies a voltage required for operation of the controller. The second power supply supplies the voltage required for operation of the controller if a voltage supplied for the controller by the first power supply is less than the voltage required for operation of the controller.
Implementation Method 2
A gaming machine design incorporating a backup power supply system, including lithium batteries and electrolytic capacitors, that maintains operation and logs abnormal events even when the main power supply voltage falls below operational levels
Data Source
AI summary
A gaming machine is provided, which includes an interface portion, a controller, a memory, a first power supply, and a second power supply. The interface portion is connected with at least one unit used for executing a game. The controller controls the unit connected to the interface portion and detects an occurrence of abnormal operation at the unit. The memory stores identification information for identifying the unit, and further stores historical information that includes information related to the occurrence of abnormal operation detected by the controller in connection with the identification information. The first power supply supplies a voltage required for operation of the controller. The second power supply supplies the voltage required for operation of the controller if a voltage supplied for the controller by the first power supply is less than the voltage required for operation of the controller.
