Abstract
The Internet Of Things (IOT) gateway plays an important role in connecting the traditional information network and network aware, in view of the present people use outdated development ways to realize Internet gateway software proposed a scheme of using real-time Java technology. This paper uses ARM cortex-A57 architecture of AMD Opteron 1100 processor as the core to build IOT gateway system hardware platform, through the gateway to realize remote monitoring of underlying device. The IOT gateway adopts "Internet + Sensor Network / FieldBus Technology" network schemes to realize wired / wireless data exchange, and use the fully compatible Real-Time Specification for Java (RTSJ) of the WebSphere Real Time development platform to achieve the Internet gateway protocol conversion and the design of the two layers network communication software to ensure the IOT gateway security real-time communication. Finally, this paper gives the implementation technique and application of the gateway.
Highlights
With the development of sensor, wireless communication and embedded system technology
The software design of the Internet Of Things gateway based on Java technology to realize the Internet of things to the Internet of things by using Real-Time Specification for Java (RTSJ) as the reference
In this paper uses AMD Opteron 1100 processor architected by the Cortex-A57 ARM and sensor network technology / field bus intelligent gateway hardware to design plan
Summary
With the development of sensor, wireless communication and embedded system technology. The WebSphere Real Time's basis is IBM's cross platform J9 technology, introducing the new advance ahead of time (AOT) compilation technology and deterministic garbage collector metronome GC It provides hard real-time performance for the system which is not suitable for the use of JIT compiler, and ensures the high real-time performance of the Internet gateway [6]. To network technology development as the background, this paper puts forward the AMD Opteron A1100 processor and Linux operating system networking gateway design scheme based on; on this basis by "Internet (Internet/3G) + sensor network technology/field bus" to the network to achieve a variety of different communication technology standards of interoperability. The software design of the Internet Of Things gateway based on Java technology to realize the Internet of things to the Internet of things by using RTSJ as the reference
