Novel Internet of Things multi-task operation system and method based on java virtual machine

Abstract

The invention relates to a novel Internet of Things multi-task operation system and method based on a java virtual machine. The system and the method are used for implementing: a software and hardware combination technology is used on the embedded equipment to realize a small multi-task operation system. The operation system supports one or more local built-in tasks and java virtual machine tasks, and meanwhile, public and characteristic function module interfaces are established for different equipment types, so that a third party can develop a program to control equipment, and the problem of closing of Internet of Things terminal device is solved. The system has the beneficial effects that cross-platform and one-time development is realized, and the system can be operated anywhere, the application range is wide and is as small as that of a single-application intelligent card, as large as multi-application intelligent air conditioners and televisions. The consumption of hardware resources is very low, and a low-end single chip microcomputer can also meet the requirement. The cost is low, the flexibility is higher, and the system expansibility is high.

Description

technical field [0001] The invention relates to a novel Internet of Things multi-task operating system and method based on a java virtual machine, belonging to the field of computer Internet of Things. Background technique [0002] In the existing Internet of Things technology, relatively large devices (such as TVs, air conditioners, etc.) are mostly large-scale systems such as Linux or Android. Due to cost issues, they can only be applied to high-end products; small devices (such as smart light bulbs, door locks) Generally, there is no operating system or ucOS and other systems, etc., rely on a specific chip platform, and have a single interface with the outside world, and the slightly high-end ones are only connected to the system developed by the manufacturer through Wifi, Bluetooth, remote control, etc., and cannot achieve a wider range. Connectivity; these are weak IoT connected systems in a strict sense. [0003] There is following shortcoming in prior art: [0004] ...

AI Technical Summary

Problems solved by technology

[0004] (1) Standardized PC and mobile phone applications using Linux, Android and other operating systems are very mature. It is indeed appropriate to apply servers or central components in large physical network systems, but most of the components in a physical network are sensor systems. And terminal devices, such as smart light bulbs, sockets, cups, door locks, etc. These devices are complex, highly enclosed, single-function, and low in price

Applying operating systems such as Linux and Android to these devices is obviously inappropriate economically and cannot be popularized on a large scale

[0005] (2) Use ucOS and other multi-tasking embedded operating systems, rely on specific chip platforms, cannot support dynamic download of applications, and have fixed external connection forms

[0007] (4) The above systems require application developers to fully understand the platform features, making development more difficult
