Abstract

The invention discloses a method and system for access control to a function module connected with an intelligent terminal, comprising: detecting the function module connected with the USB port of the intelligent terminal; determining the function module included in the USB composite device type multiple sub-functions, set a sub-device interface for each of the multiple sub-functions, and assign an interface identifier to each sub-device interface; based on the interface identifier, generate a sub-function associated with each sub-function in the security buffer of the smart terminal virtual sub-device; when the first sub-function among the multiple sub-functions needs to access the smart terminal, the first access request is sent to the corresponding first virtual sub-device in the security buffer via the first sub-device interface, and the first virtual sub-device The sub-device parses the first access request to obtain the first data content; the smart terminal stores the first data content in a security buffer, and the first virtual sub-device sends the first data content to the first sub-device interface via the first sub-device interface. Subfunction.

Description

technical field [0001] The present invention relates to the technical field of intelligent sensor terminals, and more specifically, relates to a method and system for access control of functional modules connected to intelligent terminals. Background technique [0002] With the construction of the power Internet of Things, smart terminals are playing an increasingly important role in the fields of power consumption information collection, distribution transformer intelligent monitoring, orderly power consumption, and energy efficiency management. In different application scenarios, smart terminals have different requirements for various input / output interfaces, so various types of functional modules emerge as the times require, and through the cooperation of different types of functional modules, the redefinition of smart terminals is realized . [0003] According to different application scenarios of smart terminals, it is necessary to support multiple functional modules t...
