Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an Internet of Things (IoT) service technology, and more particularly, to an apparatus and method for updating an application program of an IoT device.
The term Internet of Things (IoT) first appeared in 1998 at the Massachusetts Institute of Technology (MIT) Auto-ID Lab. In 2005, ITU-T published its annual report entitled The Internet of Things, which predicted that the Internet would be the most basic framework for all the structures of the IT revolution.
The Internet is defined as a new information communication infrastructure that connects all the things in the world with a network so that people can communicate with people, things, things and things anytime and anywhere. It is an infrastructure for realizing ubiquitous space . This ubiquitous space starts with computing devices embedded with specific functions being embedded in the environment and objects, and the environment or objects themselves being intelligent.
These Internet services provide us with more convenient and safe lives, so various mobile carriers and handset manufacturers are concentrating on the development of terminals and services for Internet applications that will emerge as next generation mobile services. In addition, personalization services and related applications linked to smart devices are increasing.
In order to verify life-friendly sensor application services based on smart devices, it is necessary to construct a test environment in a sensor network environment including an IoT device such as a sensor node, and to examine the actual operation and commercialization possibility of previously developed application services. In addition, it is essential to implement related systems and protocols for updating IoT devices supporting services in order to develop, verify, and update various services.
In particular, if you want to use the IoT device for application services different from the originally purchased purpose, smart device applications can be purchased and installed through the app market.
However, the application program of the IoT device performs update according to the interface and protocol of the AVR bootloader, the ISP or the MSP BSL according to whether the processor of the IoT device is the Atmel AVR or the TI MSP in the existing update system. That is, in order to update the various types of IoT processors, the user has to buy hardware supporting different updates according to the processor, or manually request update from the IoT device vendor (developer), which is troublesome.
The present invention provides an apparatus and method for updating an application program on an IoT device without having to have separate hardware according to the type of processor and communication method of the IoT device.
The present invention relates to a method for updating an Internet of Things (hereinafter, referred to as 'IoT') application program in a host apparatus, which performs host system environment setting for updating corresponding to profile information obtained from an IoT device, Switching to an update mode through communication with the IoT device when an application program update to the IoT device is required; and transmitting an application program to be updated to the IoT device with a protocol corresponding to the profile information to the update device .
The present invention relates to a method for updating an application program in an Internet of Things (hereinafter referred to as 'IoT') device, comprising the steps of: providing profile information to an update device in response to an update start request from a host device, And installing the program in response to receiving the application program from the update device in a protocol corresponding to the profile information.
The present invention relates to a method for updating an Internet of Things (hereinafter, referred to as 'IoT') application program in an updating device, and in response to receiving profile information from an IoT device, switching from an IoT device to an update mode And updating the application program transmitted from the host device to the IoT device with a protocol corresponding to the profile information.
The present invention can be applied to various services that link smart devices with IoT devices. In particular, regardless of various communication interfaces and processor types, it is easy to perform program installation and dynamic update of IoT devices installed and sold for personalized services. In addition, even when the IoT device is applied to other services, it is possible to easily update the Internet application program included in the smart device application.
