What is HVAC?

HVAC stands for Heating, Ventilation, and Air Conditioning, and refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling for residential, commercial and industrial buildings. They are used to keep people warm and cool in winter and summer, and keep people healthy by filtering and cleaning the indoor. Besides, they are also used for maintain the ambient temperature and humidity for things in commercial and industrial buildings, such as server room, factories, biological medicine manufacturing and storage, to keep the things at a certain level of temperature and humidity.

Before we jumping to Industry 4.0, let’s take a look at the previous 3 industrial revolutions.

Industry 1.0

Key words: water power, steam power, mechanization

The first industrial revolution was started from 1760 to 1840 in England, when steam and water power was first used to create mechanical production facilities, and has helped us to move from hand to machine, and from farms to the first factories.

Industry 2.0

Key words: electricity, mass production, assembly lines

The second industrial revolution was started from 1870 to 1914, thanks to the electricity, the electricity gave us automation and assembly lines to create a division of labor and mass production, and this is the real start of factories.

Image source: Industrial Revolution Two

Industry 3.0

Key words: computer and automation

The third industrial revolution started from 1970s when the programmable logic controllers and computers was used to manufacturing. It used IT systems to automate production lines, which has dramatically improved the efficiency and quality of production.

Image source: robotics business review

OK, after a quick overview of last 3 industrial revolution, and let’s go back to Industry 4.0.

So what is Industry 4.0?

Key words: cyber physical systems

The Fourth Industrial Revolution (or Industry 4.0) is the ongoing automation of traditional manufacturing and industrial practices, using modern smart technology. Large-scale machine-to-machine communication (M2M) and the internet of things (IoT) are integrated for increased automation, improved communication and self-monitoring, and production of smart machines that can analyze and diagnose issues without the need for human intervention

Industry 4.0 uses transformative technologies to create a cyber physical system(CPS) for future’s smart manufacturing and smart factories. The transformative technologies include Robotics, AI, big data, IoT, cloud computing, AR, 5G/4G, machine learning, etc. The cyber physical system is now not the individual computerized machines, but the whole network, that have smart machines, intelligent robots, and IoT sensors connected to the network and talk to each other. In this way, the CPS can diagnose their own problems and alert someone that something is going wrong with the machines. Besides, we also have big data technology to use and analyze the data generated by the connected machines. In addition, by using machine learning and AR(artificial intelligence) technologies, we’re able to makes things out of the data, such as predictive maintenance, where a machine or assembly line will tell us it might be going to break down in the next day, so we can fix things before they happen.

Why Need Industrial Cellular Router?

Today, the IoT has played an important role in our life, such as, automatic meter reading, ATM of bank, vending machines, kiosk, digital signage, traffic light control, etc. While just like human beings need mobile phone for daily-life’s communication, the things from IoT(Internet of Things) also need cellular router to set up a communication tunnel with cloud server, as a result, finding an industrial cellular router to provide a secure and reliable connectivity over cellular network is critical.

Industrial IoT

Benefits

For industrial IoT application, it’s better to choose industrial cellular router over consumer cellular routers, here are some reasons.

1. Robust and Reliable

It normally can operate between -35~+75^。C, while consumer cellular router normally can only operate under 0-60^。C. Besides, there is software and hardware watchdog to ensure the device can fully auto reboot and recovery if there are failures.

2. Secure

It supports multiple of VPN, such as IPsec, OpenVPN, GRE, PPTP, L2TP, etc. In additional, it supports APN, which both provides a private network for internal data transmission.

3. Smart

It is smarter than consumer router, for example, you can remotely configure the devices via SMS or commands, and use device management platform to remote monitor the status of devices anytime and anywhere.

4. Rich I/O and protocols

For industrial applications, there are diverse type interface of sensors, controllers, such as RS232, RS485, RJ45, Digital input, analog input, relay output, while the consumer cellular router only has RJ45. Furthermore, industrial sensors and controllers normally have their own protocols, such as Modbus RTU, Modbus TCP, MQTT, DNP3, etc.

To conclude, for mission-critical industrial application, those are some benefits of using industrial router.

What is IPsec?

According to Wiki, IPsec stands for Internet Protocol Security, it is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs).

IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection.

Bivocom industrial cellular routers&gateways not only support IPsec VPN, but also GRE, PPTP, L2TP,  OpenVPN, which provide a secure connectivity for your industrial IoT applications. Bivocom industrial cellular routers, IoT gateways both support VPN client and server mode.

What is MQTT?

MQTT, stands for Message Queuing Telemetry Transport, is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as water, mining, power, oil and gas, etc.

For example, in weather service application, all the sensors as publisher publish weather data to MQTT Broker, and Weather Service Center or DB subscribe certain Topic to acquire the data from Broker.

Benefits of MQTT to IoT

1. Transfer data and information efficiently
2. Save network bandwidth consumption
3. Scalable to massive IoT sensors
4. Support low-bandwidth, high latency, unreliable networks

How to Set Up MQTT on Industrial Cellular Router?

1. Configuration on MQTT Broker/Platform

• To run up the MQTT feature, we need a MQTT Broker, here we take a broker account as example from CloudMQTT.com platform

• CloudMQTT.com also provide a simple websocket UI as a publisher for quick test. The Received messages will display respective Topic with Message from publishers.

2. Configuration on Bivocom Router

• Bivocom Routers and gateways support serial communication (RS232 or RS485) via MQTT. Before go into setting, please connect your slave computer like PLC or sensors to RS232 /RS485 ports on Bivocom router. In this case, we take Bivocom TG451 as a demo.
• Bivocom standard package contents Console Cable(3-Pin RS232), connect one side to RS232 ports on Bivocom router (the Black pin to GND port, while Brown pin to RX port, Blue pin to TX port). The other side connect to your slave computer, you may need extra adapter cable if your PLC/sensors don’t have standard serial communication interface.

• Go into the WebUI of Bivocom router, >> Advanced>>Serial Communication, Enable Serial 485 or 232 >> Select MQTT as protocol.
• Input the necessary MQTT server info we got from step 2, Save & Apply, if everything was correct, the Connection Status will indicate “CONNECTED”

• On the CloudMQTT.com platform, you can also check the CONNECTIONS list the Bivocom router IP address on. After that, you are able to perform MQTT publisher on Bivocom router.

3. MQTT Feature Demo

• To simulate the slave computer, we use a simple serial communication tool running on PC which connected to Bivocom router via RS232. Then send data as publisher to MQTT Broker.

• MQTT server will receive the message with Topic we have set on Bivocom router

• To subscribe the data, we use a simple tool as subscriber.
• Connect the tool to MQTT server
• Set the exact subscribe Topic, it also supports the variable parameter like “#” “+”
• On the data window, shows the received data from publisher accordingly.

Wikipedia gives air compressor definition as below.

An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank’s pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air Compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.

There are two main designs for the majority of air compressors: reciprocating piston air compressors and rotary screw air compressors.

Who Uses Air Compressors?

Air compressors have been widely used in many industries and applications, and different application calls for different type of air compressors. Air compressors can be grouped into three classifications: consumer grade, professional grade and industrial grade

1. Consumer Grade

Small and portable air compressors that we’re using in our daily life, such as, air compressor pumps to inflate vehicle and bicycle tyres, or pressure washing, spray painting, etc.

Inflating and Spray Painting

2. Professional Grade

Construction may use the air compressor to power the drills, hammers and compactors, while for agriculture or farming, the air compressors have been used to power tractors, sprayers, pumps, and crop conveyors.

Construction and Farming

3. Industrial grade

For manufacturing, air compressors are used to power the conveyor belts, sprayers, presses, and packaging. Besides, application like Heating, Ventilation and Air Conditioning (HVAC), Rotary screw air compressors conduct vapour compression refrigeration that entails compressing air vapours, raising the temperature, and modulating the all-important refrigerant cycles. Oil drilling relies on air compressors for functionality in the energy sector.
