Activity
With the introduction of locking and exclusive access, there is another concurrency-related problem: the progress of the inference contract implementation and the activity attributes. For example, it is not difficult to imagine a situation where a specific account registered as "reader" in the example in Figure 5 might never release the reader lock, preventing others from changing the future status of the contract. Being active in this situation means that there will be good things in

Intelligent Mansion (Intelligent building) is the product of the development of modern information society, it has become the development direction that the contemporary construction industry and the electronic information industry jointly seek. At present, the governments of all over the world and the transnational enterprise groups have expressed great concern to the
With the continuous development of information technology, the Integrated Wiring System is well interconnected with communication and graphic display technologies. It is also closely linked with intelligent buildings, but in practical application, there will be many problems, which requires a more integrated "compatibility" between the two ".
I. Development of Integrated Wiring System
In 1950s, the economically developed countries created a large high
Sino Intelligence (Wuhan) technology Co., Ltd.Construction scheme of open intelligent classroom Training System 1 Smart Classroom Project development background 1.1 Internet of Things technology With the popularity of network coverage, people have raised a question, since the ubiquitous network can become the omnipotent tool of interpersonal communication, why can't we use the network as the tool of communication between objects and objects, the tools
Integrated Intelligent Network can effectively use the original intelligent network, at the same time better for a number of network users to provide a comprehensive, unified business, its main purpose is to use only a set of network for fixed network, mobile network (including GSM and CDMA), IP network to provide business logic, Provide users of these networks with an
continuous development of science and technology, especially the communication, computer network, control and graphic display technology of mutual integration and development, high-rise building services and the increase of the objective requirements, the traditional professional wiring system has been able to meet the needs. To this end, developed countries began to research and launch the integrated wiring system, the the 1980s later integrated wiring system gradually introduced to China. In
