Plug-and-play conversion circuit and method for peripheral of Internet of Things

Abstract

The invention discloses a plug-and-play conversion circuit and a plug-and-play conversion method for peripheral equipment of the Internet of Things, and belongs to the technical field of the Internet of Things. The plug-and-play conversion circuit comprises a peripheral slot, an onboard ID input unit, a shift register and a microcontroller interface, the peripheral slot comprises a plurality of slots, and pins in each slot are arranged at specified intervals; the onboard ID input unit is used for inputting a peripheral ID of a peripheral to be inserted by a user; the shift register is a parallel-in serial-out shift register and is used for recording the use state of each slot and the peripheral ID input by a user as peripheral ID data of the current peripheral and outputting the peripheral ID data to the Internet of Things control equipment; and the microcontroller interface is used for providing a data transmission interface between the microcontroller interface and the micro-control unit. The invention further discloses a peripheral plug-and-play method based on the plug-and-play conversion circuit. The universal peripheral interface circuit provided by the invention can be used for conveniently accessing the peripherals into the system of the Internet of Things, and does not need a customized peripheral interface like a traditional system of the Internet of Things.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a plug-and-play conversion circuit and method for peripherals of the Internet of Things. Background technique [0002] Various information collection devices are connected to the network to form the Internet of Things (IoT), so that these individual objects that carry information can be connected to form a huge information network, which facilitates the identification, management and monitoring of individual objects . That is, through the widespread deployment of spatially distributed devices with embedded recognition, sensing, and actuation functions, applications such as the Internet and the Web will be extended to the physical realm. Connecting the digital world and physical entities through appropriate information and communication technologies enables a whole new class of applications and services - the "Internet of Everything". At present, the I...
