4 System function introduction
4.1 LonWorks monitoring system
LonWorks is a set of control network technology that contains a variety of hardware and software products and services. This technology has become a universal and open industry standard recognized in the field of global control equipment. This technology integrates multiple devices to monitor sensors, control actuators, provide reliable communication and manage network operation services, and can access network data locally or remotely. In a sense, the LonWorks control network is like a data network (similar to a local area network). The data network is composed of multiple computers, which are connected to different communication media through routers, and the communication between the computers in the network needs to be completed through a common communication protocol. Network management software enables managers to configure and manage computer networks. The control network also includes similar components and systems, but it is superior in terms of cost, operation, volume, and response characteristics required for control, and its application fields are far beyond the scope of the data network. At the same time, the LonWorks control network is a universal and open measurement and control network, and it can use the existing products of many manufacturers and has the advantage of not being restricted by the network communication protocol. LonWorks control network technology can be used in almost all major industrial industries, including factory plant automation, production process control, building and home automation, public facility monitoring, medical and transportation industries, etc.
The LonWorks networking mode is flexible and can adapt to multiple structures such as bus, star, ring, free topology, etc., especially the free topology structure is particularly suitable for residential applications. Therefore, the system uses the LonWorks network as the backbone to carry the monitoring network, and is connected to the computer local area network through the switching equipment to form an intelligent security management system for residential quarters and a modern communication network system.
The LonWorks monitoring network system has three main subsystems in the community: home security alarm system, remote automatic meter reading system, and surrounding anti-overstep alarm system.
The LonWorks network system consists of a monitoring host, various control modules (also called nodes), routers, and network connection lines. The system uses twisted-pair wires to connect the monitoring host of the LonWorks monitoring network system of the community management center, the remote automatic meter reading module of the residential unit of the building, the home security alarm control module, and the peripheral anti-overstepping node control module to form the LonWorks of the community. Monitor the network system.
The first phase of the Jinbao Pioneer Homes Residential District includes two communities, No. 2 and No. 3, with a total of nearly 2500 nodes. Due to the large number of nodes and most of them are alarm data, we have adopted the method of incorporating node output network variables into host network variables, which can respond to alarm signals in time and avoid the busy network caused by querying all nodes.
