Guide on Embedded Computers

Some of the benefits of embedded computers include:

• Small Factor Size :
  Embedded computers are a part of large devices, hence they generally use small factor motherboards. They also use advanced cooling systems and modern enclosure designs that allow them to be as small as possible. Most industrial embedded computers come without fans, relying on thermodynamic principles to cool down.
• Highly Reliable :
  These computers are highly reliable in every condition and situation, making them suitable for critical mission-based applications such as military or industrial deployments. Embedded computers are built to withstand demanding applications and extreme environments, including continuous vibration, rugged terrains, and high temperatures. In fact, these embedded computers are able to operate at a wide range of temperature (from -30°C to 70°C) as well as resist dust and humidity.
• Power Efficiency:
  Embedded computers need to be able to operate day and night, 24/7. Due to this, power efficiency is extremely important in embedded computers. To reduce the need for high processing power, embedded computers come with lightweight and dedicated software, and do not use any moving components such as fans that may increase power consumption.

Characteristics Of Embedded Computers

Although embedded computers are used in a wide range of special and specific-function systems, there are similar characteristics between them that provide benefits to the applications.

These characteristics include:

• Small Factor Size - The small form factor of the embedded computer allows it to function in tough locations and conditions. Soldered components and SoC design reduce component complexities, making embedded computers ideal for tight locations and rugged deployments.
• Passive Cooling System - Embedded computers do not use mechanical fans. Instead, they use a passive cooling system that utilises heat pipes and heat sinks. Embedded computers also tend to use low thermal design power (TDP) components together with the passive cooling design, allowing them to dissipate harmful heat generated by components. This makes embedded computers especially well equipped for rugged applications where temperature may not be under control.
• Rugged Design - Embedded computers feature a rugged design, allowing them to resist shock and vibration, withstand wide voltage, and work in a wide range of operating temperatures. These features are key in minimising points of failure and ensuring that embedded computers function with stability and longevity. Wide voltage protection is crucial for environments that may experience spikes in voltage. Resistance against shock and vibration are essential for in-vehicle applications.
• Low Maintenance and Reliability - Embedded computers are designed to be reliable and low in maintenance, which explains the fanless and cableless design as well as the minimised number of moving components. The lack of moving components also means reduced risk of damaged components when products with embedded computers are used in rugged environments, where elements of shock and vibration are present. These embedded computers need to be reliable to perform continuously 24/7 as per the situation's need.
• Dedicated Nature - Embedded computers are built in a way that allows them to take advantage of customised software to minimise hardware requirements. For example, Microsoft has developed a version of Windows (Win 10 IoT) that specifically targets embedded and IoT applications, offering developer tools and informative support.
• Low Power Consumption - Embedded computers use power-efficient processors that ensure the internal components do not generate a high amount of heat. Power efficient processing also eliminates the need for moving components and fans, which then reduces power consumption, resulting in overall lower costs.
• Internet Of Things (IoT) - This feature allows those using embedded systems to transform their products using Artificial Intelligence (AI), machine learning, and edge computing. The IoT's role is to collect all the sensory data together with the processing capabilities of embedded computers, so that they can be analysed and used to achieve required results. IoT plays an important role in encouraging companies to improve their productivity, and to change the way they approach business.

1. The Rugged Industrial Box PC

These are built tough with sophisticated cases to keep the embedded computers safe in rough conditions. Generally, these cases are made of ionized aluminum, which makes them strong, durable, and safe to use in an external environment even without extra protection. The case keeps the rugged computer resistant to corrosion, dust-proof, and humidity-resistant, allowing it to be installed outdoors without requiring any extra layer of protection. The electronics within the computer are also made to be robust and strong. The rugged industrial box PC is effective for remote facilities, such as offshore oil rigs.

2. The Panel PC

Panel PCs are available with an integrated display screen and keyboard, and occasionally an all-in-one touchscreen. These PCs can be changed or expanded with different I/O modules as per the industry standard. These embedded computers are created to provide better and easier interaction with humans through its screens and interfaces. Some Panel PCs feature touchscreens that can be controlled through work gloves, and are protected from toxic materials and shock. Panel PCs are ideal for places where people may not be able to access, such as food processing machines, big robot arms, packaging industry, and more.

3. The Mini PC

These are low-computing embedded computers that are small in size and are available at a cheaper cost. Mini PCs are ideal for use in small confined places where some intelligence is needed. For example, a mini PC embedded computer would work very well as a security device in network installations, such as a Firewall or a VPN router. It is often used in manufacturing facilities or industrial installations that require constant operation and security in harsh conditions.

4. The Industrial Rackmount Server

Rackmount servers are a type of embedded computer designed to be installed in a rack. Unlike the tower server, which needs to stand by itself, rackmount servers can be put on the rack with other servers stacked on top. Industrial rackmount servers come with a powerful CPU and memory, and are considered rugged high performance computers ideal for challenging and harsh conditions. Industrial rackmount servers are extremely high performing, and can tolerate a wide temperature range (-40~70°C).

5. The Vehicle Computer

In-vehicle embedded computers are designed to be installed in vehicles. They are rugged fanless devices that can withstand vibration, harsh temperature, humidity, and dust, as well as operate in a wide range of temperature. They also feature wireless capabilities to support mobility and long range communications, and are suitable for applications including emergency response vehicles such as ambulance, police or firefighters.

6. IoT Gateway

The IoT gateway works like a bridge between different types of communication technologies, which can vary in terms of connectivity types, interfaces, or protocols. The IoT gateway provides a connection between the IoT sensors and the Internet, collecting data from external sources, translating protocols and pre-processing the data.

The Advantages of an Embedded System

Embedded computers have many advantages, including:

• The central processing core in embedded systems is built in a way that makes them less complicated and easier to maintain. As they are designed to have a limited function, this allows them to be more efficient when performing their tasks.
• Embedded systems have smaller parts, which reduces the cost to build and produce them.
• As they are located inside another device, embedded systems are not as accessible and easy to service. Because of this, greater care is taken when they are developed. Also, because they are almost inaccessible for repair, most embedded systems are programmed in a way that they will not affected other related systems if they malfunction.
• Embedded systems are easy to maintain, as their power supply is within the system and they do not need any remote maintenance.
• Embedded systems do not use or need the redundant programming and maintenance involved in other system models.

Disadvantages Of Embedded Computers

• They can not do multiple tasks as they are designed for a specific function.
• Does not support external devices.
