TouchThink Industrial Computer Enhances the AI Proctoring System, Safeguarding Fairness and Justice in Exam Venues
Industry Background
In China, the college entrance examination (Gaokao) is currently a national focus during June. As a matter of great significance concerning the future and destiny of examinees, safeguarding the order of examination rooms and upholding the fairness of the examination has always been a key issue that affects the nerves of the whole nation.
Application Requirements
The AI-powered intelligent exam proctoring system is based on fully digital audio and video analysis technology. It captures video streams through high-definition cameras deployed at the front end, and then uses AI algorithms and intelligent analysis models to accurately identify risks in examination rooms.
To ensure the information security of examination rooms, exam venues typically use a dedicated educational administration network and are equipped with wireless signal shielding devices, isolating wireless public networks such as 4G and WiFi. Allo stesso tempo, in order to achieve real-time alarm push and rapid processing of abnormal behaviors in examination rooms, edge computing terminals with computing power are required to perform preliminary AI recognition on video sources. Therefore, when customers are seeking supporting industrial computer devices, the requirements are:
- Network Transmission: Must support 2-channel Gigabit-level wired network transmission with high real-time performance and low latency to ensure stable and fast data transmission of video streams.
- Computing Power: Require certain computing capabilities to support high-definition video decoding, optimizing decision-making and analysis efficiency for real-time monitoring and risk identification.
- Processor: Adopt embedded domestic low-power processors to ensure the system’s security, controllability, and energy efficiency, meeting the needs of long-term stable operation in examination environments.
TouchThink IPC Solution
Facing the above requirements, TouchThink has delivered a personalized IPC solution – TPC08 – AIOT. With its stable, intelligent and efficient characteristics, it safeguards the fairness and justice of the examination room.
Low-Power Processor
ILTPC08-AIOT is a senza fan & low-power ultra thin industrial computer powered by the Rockchip RK3568 quad-core processor. It integrates a1 TOPS dedicated NPU EMali-G52 2EE GPU graphics unit, supporting4K decoding E1080P encoding. This enables real-time output of high-definition video streams to monitoring displays with AI preprocessing, instantly flagging suspicious behaviors for human verification, thereby enhancing real-time response capabilities.
Customizable Hardware Modules
Tailored for exam environments, we removed WiFi/4G wireless modules and upgraded to dual Gigabit Ethernet ports for enhanced network reliability. This configuration:
- Connects securely to educational exam video private networks.
- Enables real-time data synchronization and transmission to centralized AI monitoring platforms.
- Ensures precise delivery of video information to the AI intelligent inspection system.
Benefits:
- Cost-Effective: Eliminates unnecessary features to reduce costs.
- Network Stability: Wired connections prevent interference from wireless jamming devices.
- Compliance: Meets strict security requirements of educational institutions.
This flexible customization not only meets specific customer needs but also optimizes cost efficiency by avoiding payment for unused features.
Custom Firmware Empowers Efficiency and Gain
To achieve efficient adaptation to scenario-specific functions, TouchThink also provided the client with customized firmware technical support in this case. It ensures the compatibility and stability of hardware-software configurations in aspects such as screen output and network policies, helping the client enhance examination room deployment efficiency and system security.
Achievements in Case Applications
The modular dedicated board structure and industrial-grade protection design of TPC08-AIOT ensure its long-term reliable operation. Equipped with an AI intelligent inspection system, TouchThink’s industrial computers have been widely applied in scenarios such as Gaokao examination rooms and postgraduate examination institutes across provinces and cities, resolutely safeguarding the credibility and solemnity of exams with their robust industrial performance.
