Types of IBMS protocols

BACnet protocol
BACnet stands for Building Automation and Control Network, a standard data transfer protocol for use in automation and building management that allows the transfer of information between systems and devices. This protocol is designed by the American Association of Heating and Air Conditioning Engineers. Several worldwide automation systems are used in ISO 16484-5, and in 2003 the International Standard
BACnet is an open source license that unites the manufacturer and license free of charge, integrating all building systems in a worker network with increased convenience, energy savings, increased security, and lower costs.
BACnet Basic Principles
The BACnet protocol specifies how to transfer data (data frames) from one device or system to another. Messages can contain the following information
& bull; Binary input and output values ​​(pump on / off or open / close window)
& bull; Analog input and output values ​​(current in a temperature sensor, control voltage for a valve)
& bull; Analog and binary input and output values ​​(reading temperature from a temperature sensor)
& bull; Timing information
& bull; Event and Warning Information (Motion Detection Sensor, Contact Point)
& bull; Files (to enhance the security configuration settings)
& bull; Control logic
BACnet messages can be transmitted via Ethernet, MS / TP, LonTalk, ZigBee, or ARCNET. Using the LAN in the building intranet is a good choice. For long distances, point-to-point and Internet telephony is more suitable
& ldquo; Objects & rdquo; Used to communicate with devices and their applications in the BACnet network. If any automation unit is considered as a set of information structures or objects, assuming that the device has 4 digital outputs and 2 analog inputs and 1 controller, then this device must have an object for each of these components. Each object has specific properties (name or current status) that can be read or written. These objects enable you to retrieve specific device information without knowing anything about its structure or configuration. A similar function can be implemented with different hardware or software. Using standard objects, devices that are produced by different companies operate easily with each other

LONWORK protocol

This technology is a new design to realize the unconnected communication systems of auto-building devices, the industrial application Echelon and more. In fact, the collection Of the devices and components for the design and implementation of control networks, which was introduced by the American company (). This technology includes all the components needed to design and support networks corporation

The following are the specific components of the control:

& nbsp; & nbsp; hardware neuron chip and other advanced tools lon works _ Transmitter and receiver lon talk neuron chips_protect

& nbsp; & nbsp; Which was produced by Motorola in several models. lon works based on

& nbsp; : lon works Benefits

This technology ensures that many makers produce unstructured network tools such as sensors, drives or controllers that work together because they use the general-purpose communication protocol They can exchange data with one another.

: & nbsp; It allows us to lon works so

Engineers should not focus on design, best use, and attention to communication protocol, hardware, software, or operating system.

Participate all techniques in a building.

Users can select a huge amount of pieces.

It is easier to add, move, and replace components to control the network at any time. lon works

On an almost infinite network. node Based on the number of

This technology is highly consistent and matched with many private control systems and well-focused systems.

In this technology, centralized systems operate on a peer-to-peer connection.
