GB/T 28847.1-2012Building automation and control systems - Part 1: Summarize (English PDF)

2.1 Building automation and control

In order to achieve energy efficiency, conservation, safe operation of facilities serving the purpose of the building, and monitoring with automatic control, optimization and management activity.

2.2 Building automation and control systems

It can be realized on various types of equipment distributed monitoring and management systems, including automatic control, monitoring and optimization of products and engineering services.

2.3 Interlock

For controlling the sequence, a Boolean logic devices and closed-loop control, on/off control of the operation of an open connection to another device.

2.4 Closed-loop control

Output to the difference between the measured value and the expected value of 0 is reduced to the method of process control work.

2.5 Open control

One or more measurement input in the process there is no continuation of the impact of the conditions on the input control work.

2.6 Analog signal

Continuous time and continuous numerical information characteristic signal.

2.7 Coupling

Closely with the presence of interaction between two or more elements of the input and output circuit or an electrical network, and through interaction

From side to side with the energy transfer phenomenon.

2.8 Pulse signal

Time discrete signal characteristic information.

2.9 Transmitter

Output means prescribed type and value of the signal.
