摘要： The disclosure relates to a life prediction system for a fan of a lamp. The system comprises a fan signal detecting module to detect at least one working parameter of the fan; and a micro control unit to receive the working current signal, the environment temperature signal and the working rotation speed signal of the fan. The detecting module comprises a current detecting unit to detect a working current of the fan and output a working current signal; a temperature detecting unit to detect a working environment temperature of the fan and output an environment temperature signal; and a rotation speed detecting unit to detect and output a working rotation speed signal of the fan. The micro control unit calculates a predicted residual life of the fan based on the received working current signal, the environment temperature signal, the working rotation speed signal, through the life model of the fan.

摘要： The present invention discloses a business operation mode based on artificial-intelligence+legal-affairs+business-affairs. AI is the empowerment, legal-affairs' main-body, business-affairs' framework. AI characteristics lie-in two-learning or two-experts, including Internet-of-human, Internet-of-things, Internet-of-intelligence; applying AI computer-program to control or improve business-quality. AI+legal-affairs innovation lies-in new-brain or new-procedures, using contract to authorize AI's basic-role in judicial-affairs. Identification or adjudication is made by deep-learning and reinforcement-learning, both priorities accept. Experts separately verify evidence or fact, video-trial, mediate then arbitrate. Expert-database complements expert-system each-other, explains algorithm, and promotes reconciliation. Financial-experts control credit-limit and perform-contract through guarantee insurance. AI+legal-affairs+business-affairs characteristics lie-in two-lines or two-supports, applying AI to verify the credit of excellent business-subjects or business-quality, and control to improve business-process. To improve business-quality, focuses are on AI-health, AI-teaching, AI-traffic, or other public-services.
