North China Electric Power University (华北电力大学)

Solution

North China Electric Power University built the 'i Huadian' assistant with Baidu AI Cloud as a campus-wide service for students and staff. The implementation combines Qianfan AppBuilder with a 'ERNIE 4.0 + Super Assistant' pattern: a very large model handles deep understanding and response generation, while a smaller intent-recognition model helps route users to the right business application or answer path. The assistant supports multi-turn dialogue for everyday needs such as checking notices, phone numbers, workflows, courses, meal-card top-ups, library borrowing, and document lookup. Just as importantly, the service was designed for controlled deployment: the Super Assistant's core application services run in a private on-premises machine room so institutional data stays inside a protected environment while operating cost remains manageable. The result is a conversational front door that links fragmented campus systems into one secure and easier-to-use experience.

Data flow

Campus notices, guides, workflows, and application-entry data are connected to the assistant, where Qianfan and ERNIE provide broad language understanding while a smaller model routes intent. Users ask questions in natural language, the assistant returns answers or pushes the right business-system entry point, and the full interaction remains inside the university's private deployment environment.
