Jini technical principles and characteristics
Jini is a truly dynamic service-based distributed architecture, which abstracts both devices and software as services and supports the formation and dissolution of dynamic groups. The Jini group (also known as djinn) refers to a set of devices, resources and users, and Jini software infrastructure. The Jini group is a logical network formed on an existing physical network (Local Area Network LAN or Wide Area Network WAN). The Jini group does not have to be completely mapped with the existing physical network, and multiple Jini groups can be established on one physical network. Each Jini group is independent, self-configurable, and self-managing, and can also accumulate small Jini groups to build a large djinn. The minimum components needed to form the Jini community are:
(1) A search service.
(2) A tool with RMID for RMI to activate its system background program.
(3) A group of Jini services / service providers.
Jini technology has:
(1) The services implemented are independent of the specific location.
(2) It has nothing to do with the agreement.
(3) Loose coupling.
(4) Dynamic and self-management.
(5) Features such as dynamic security. The remote event mechanism provided by Jini allows the system or system users to sense and schedule events in the network in a timely manner. The lease mechanism provided by Jini can avoid the impact of partial failure on the system.
This article uses Jini group architecture to define a set of equipment, resources and users for chemical experiments, and abstracts a series of services in the experiment, so as to give full play to Jini's technical characteristics and advantages.
Design and Implementation of Virtual Experiment Platform Based on Jini Technology
Reset Lockout
Prevents reset if GFCI is damaged or failed to provide ground fault protection
Complies with NEC ® requirement, by blocking access to the contacts unless the plug is fully inserted
Only 1.22" Protrusion into Wallbox
Takes up to 20% less space in the wallbox vs. other GFCIs for easier installation
Multi-functional Status Indicator Light
Red and Green LED indications provide simple, intuitive feedback on power, voltage and protection status
Terminals Withstand
Tolerate high-torque;power tool installation;and prevents wire pullout
Tamper-Resistant Shutter mechanism
TR GFCI UL,New Version TR GFCI UL,TR Socket GFCI Outlets,New VGersion GFCI with TR Receptacle
