Review and Selection guide for monitoring control equipment

Using features that make the home bright has always been essential for human beings. During different periods of technological development, they have created several solutions for this purpose. A smart home is a home in which the occupants can adjust and control their home equipment remotely and closely and can define and implement various programs and scenarios for that equipment—in general, equipping a building with a set of equipment that is designed and implemented to increase productivity and create a more pleasant environment for its residents is called building intelligence. The purpose of implementing innovative projects can be to transform the use of space into a more desirable, distinctive, and luxurious space and turn a building into a building with optimal energy consumption or turn a house into a modern and safe house with intelligent management. In this article, we have tried to acquaint you briefly with the types of monitoring and automation control tools and their functions.

What is BMS?

Building Management System (BMS) or Building Automation System (BAS) refers to a system installed in a building that allows the user to control different parts of the building and display the appropriate outputs through its components. The various parts under control usually include mechanical installations, air conditioning (HVAC), and lighting equipment extended to safety systems, fire, access regulation, emergency power supply, etc. Generally, the BMS systems used in a building adapt the operating conditions of different components according to the environmental conditions and the needs of the building at that time.

BMS Components

BMS Hardware:

Includes central controller, interface modules, sensors, a communication platform, user interfaces and BMS central server

BMS Software:

 A BMS Software Includes intelligent system planning software trained by the operator. According to the implemented hardware, control systems are used. The required scenarios of the building, the task of loading the required programs of different parts of the intelligent building, including Equipment time management software, alarm management, space access management, control and monitoring software via the Internet, email, and SMS, etc. are responsible for the complete guidance of a collection.

The goals of building intelligence

• Increase the level of well-being and comfort
• Enhance the beauty and decoration of the building
• Ability to upgrade equipment
• Energy saving
• Increase the useful life of the equipment
• Value-added of the building

Applications of BMS technology

Building Management System, Building Automation System and Building Control System are all closely related terms used for building intelligence. Some of these systems may exist independently, but their implementation is an integrated intelligent system. They give more coherence and intelligence to the building management system.

Building intelligence includes control and monitoring of the following systems.

• Control and monitoring of air conditioning systems
• Control and monitoring of central installation systems (engine room)
• Control and monitoring of lighting systems
• Control and monitoring of traffic control systems
• Control and monitoring of peripheral equipment (CCTV camera and security sensor)
• Control and monitoring of fire alarm and extinguishing systems
• Control and monitoring of elevator and escalator systems
• Control and monitor building energy consumption (water, electricity, etc.)

In general, intelligent building control systems can control and monitor many of the equipment used in buildings, which is mentioned below. But the site's primary purpose is to use intelligent building control systems to precisely control and precisely monitor air conditioning, heating, and engine room equipment.

Engine room control, monitoring and intelligent system

The intelligent control system of the engine room is a system through which the equipment inside the engine room is used according to the heat needs inside the building. Detection of this need through sensors that instantly collect information inside and outside the building is transmitted to the data center through communication platforms and intelligent controllers and control equipment issue the necessary commands to achieve the desired conditions in the summer. Or in winter, they run the engine room equipment. This causes, in addition to reducing the fuel consumption of the engine room, the amount of equipment depreciation is reduced, and the thermal comfort inside the building is set to its standard level. Excessive energy (thermal) production is prevented.

Joint monitoring, intelligence and automation systems

• PLC: Programmable Logic Controller
• BMS: Building System Management (Building Management System)
• HMI: Human Monitoring Interface

One of the types of equipment used in PLC systems is an electrical panel, which includes other equipment mentioned below.

Electrical panel

A switchboard is a cabinet for electrical or electronic equipment on which switches, control knobs, and display devices are mounted. Electrical switchboards are used to prevent electric shock to equipment users and to protect equipment against environmental factors. The electrical panel is the only part of the equipment that users can see; therefore, its appearance is considered in its design. Generally, the engine panels of the house are of the standing type, and the rest are of the fully closed type.

Electrical switchboards types

• Low-pressure switchboard
• Medium pressure switchboard
• High-pressure switchboard

inverter

An inverter motor protection relay is an electronic device that converts direct current (DC) to alternating current (AC). The converted AC can be based on the need at any voltage and frequency controlled by suitable transformers and circuits.

inverters features

• Starting three-phase motors with single-phase electricity
• Set start and stop time from 0.01 to 3600 seconds (in two steps)
• Adjust engine movement (left and right)
• Equipped with PID Control system
• Engine speed control by volume and external digital keys
• Has RS 485 communication port
• A quick stop by the brake
• Minimize noise by using filters

inverters applications

• Change engine and compressor speeds in air conditioners
• Pumps and fans, cranes, elevators
• Elevators, automatic doors
• Textile machines, machine tools
• Blowers, washing machines
• Extruders, conveyor belts, mixers
• Packaging machinery and industry
• Special machines such as wood factory
• Gym machines and other industrial machines

The contactor is used in general and is used in all electrical panels. Such as electrical panels in the cement, oil and telecommunications industries etc

Overload Bimetallic

Overload is a motor protection device against overcurrent and is available in two types, magnetic and thermal. This type of overcurrent relay with a contactor in the circuit is installed in series with the motor. Bimetallic overload in the automatic switch is also used to protect against high currents.

Thermal overload

Overload thermal is made in different types, the most common of which is "bimetal." This type of overcurrent relay is installed in series with the motor in contact with the contractor. Bimetallic overload in the automatic switch is also used to protect against high currents.

Magnetic overload

Its magnetic type is a coil that, due to the passage of high current (more than the set limit), the intensity of its magnetic field reaches the level necessary to perform the mechanical operation of the circuit breaker and cuts the circuit. This overload is also used in automatic switches to protect against short-circuit errors.

Advantages and disadvantages of bimetal

Advantages of bimetal over bullet fuse

• In the event of a fault in one phase, the other two phases, in addition to the control circuit, will stop working
• The higher the current intensity, the higher the bimetal sensitivity
• If there is a continuous 10% overload, the bimetal will cut off the circuit after 2 hours
• If the current reaches ten times the rated current, it will cut off the circuit in less than 2 seconds

One of the disadvantages of bimetal is its sensitivity to ambient temperature

circuit breaker

The circuit breaker is a switch that disconnects and connects the line and is also responsible for protecting the network and separating the defective part in the event of a short circuit due to the operation of the relays.

Vacuum contactor

In a vacuum contactor, the contactor is ignited in a vacuum environment, and the input and output voltages are from 3.6 volts to 7.2 kV. Usually, the current range of these contactors is 400 amps.

Compact automatic key

Compact automatic switches are from the family of automatic switches, the softness of these switches is from 15 amps to 1250 amps, but these switches are made up to 1600 amps—the frame of these switches increases as their nominal current increases.
The automatic compact switch is public and is used at the input of all electrical panels.

Automatic air switch

These switches are other types of low-voltage automatic switches that are used in high amperage. The upper current limit of these switches is up to 6300 amps.

Miniature Key (MCB)

Low voltage switches are usually used in low currents and in lighting and distribution panels with low power or to protect the control circuits and control of electrical equipment and facilities, which in case of problems in the circuit, will automatically close the circuit.

Motor protection relay

A motor protection relay is used to protect electric motors directly. In addition to the types of protection for the motor, it allows for displaying the current of each phase and the error types and installing the relevant display on the panel door via an interface cable.

Damper motor

Generally, a damper is a flow blocker responsible for opening and closing or regulating and controlling the flow of air passing through any path, such as inside the duct, chimney, etc. For example, a damper is used to cut off the incoming airflow to a room or to adjust the amount of duct air flow to each room to regulate the room temperature and is used as a tool for air conditioning.
For example, when starting any heating device, ensure the air damper is open because closing the damper is extremely dangerous and can cause bites or fires.

Types of dampers

Dampers operate manually and automatically (servo motor). Manual dampers are controlled by hand and external lever, and automatic dampers are done by servomotor damper motor. Another type of damper is called Zone Damer or seasonal damper, or volume control damper, which is used to control the cooling and heating system and is usually electric. In this type of damper, the motor and the damper are connected by mechanical coupling.

Damper motor and its performance

A damper motor is a motor located on the damper. It performs the same function as the damper, with the difference that it operates automatically, and it is possible to adjust the damper to the desired level. The damper motor has two models of return spring and non-return spring, and both models operate as disconnected and connected and gradually control the airflow. Each damper motor has a particular torque appropriate for the type of damper. Reversible spring damper motors are primarily used in ductless dampers, air inlet and return dampers, water disconnection and connection, and other fluids in various water, sewage and food industries. One of the essential applications of smoke and fire damper is to prevent fire transmission inside the ductwork system and other areas. This type of damper motor is equipped with a sensor sensitive to smoke and fire, which at a temperature above 70 degrees Celsius, orders the closure of the airflow path.

Manual damper and its function

Sometimes, the dampers operate semi-open and closed, such as the air intake combustion burner of the burners in the home capacity or the manual damper inside the fireplace, which is manually adjusted by a controllable lever.
