What Makes a rugged computer Tough and Durable? (8 Key Features)
The strongest rugged computer is a rugged computer that can fully operate 24/7 in extreme environments while maintaining its performance, durability, reliability, and longevity. A well-designed rugged computer is tested and validated to ensure its ability to withstand extreme environments that include extreme cold or heat, shocks, vibrations, dust particles, water ingress, high voltage fluctuation, and more.
Rugged computers are capable to withstand extreme environments because they are engineered and designed with the latest techniques in thermal dynamics, material science, and precision engineering. Here are some of the common features in a rugged computer that makes it durable and tough:
1. Wide Temperature Range
One of the crucial characteristics of a rugged computer is to have a wide operating temperature range to withstand extremely hot and cold environments. Many industrial devices are deployed in environments where standard desktop computers will fail when exposed to extreme temperatures.
For instance, outdoor settings can quickly reach up to 60℃, creating a scenario for electronics to overheat and fail. These high heat use cases can easily overheat standard desktop computers causing critical components like the CPU to throttle its performance or even worse, fail. A freezing cold environment can also be a problem for standard desktop computers to operate successfully. Freezing cold industrial environments can reach as low as-40℃ and can quickly cause downtime due to the computer’s inability to operate properly.
That said, rugged computers are designed with thermal engineering techniques to ensure wide temperature support ranging from -40℃ up to 85℃ for optimal performance in these extremely hot and low temperatures.
2. Shock and Vibration Resistance
Another essential characteristic of a rugged computer is its ability to endure shock and vibration resistance. Some industrial applications often involve constant shock and vibration which, is also one of the main factors standard desktop computers are not suitable for these settings. When shock and vibration are present in specific applications, it can be highly detrimental for computers that have not been tested for these environmental challenges. Therefore, a purpose-built rugged computer is specifically designed to meet these challenges through its unique mechanical design. Everything from the use of cables, excess screws are eliminated to ensure the reduction of common failure points. Moreover, rugged computers also use solid-state storage drives (SSDs in order to remove the use of physical spinning disks which, can be corrupted in kinetic settings due to constant movement.
When it comes to specific designs to endure shock and vibration, there are several key designs to ensure reliable resistance. A rugged computer will feature the use of a fanless design, cable-less design, one-piece chassis, industrial-grade materials, and the use of SSD instead of HDD for a secondary storage solution. Furthermore, well-designed rugged computers also adhere to military standard MIL-STD-810G for shock and vibration resistance. For these reasons, rugged computers are great for transportation solutions that include in-vehicle, autonomous vehicles, ADAS, and railway systems.
3. Ingress Protection
Industrial computing applications oftentimes also require resistance to s dust and water, also known as ingress protection. From outdoor rain, marine applications, to extreme washdowns for hygienic sanitizations, rugged computers are also designed in a way to protect themselves from damaging dust, debris, and water intrusion. Fully waterproof rugged computers are configured with M12 I/O connections. M12 connection is known for its durability and reliability against extreme water and dust exposure because of its locking feature. M12 connectors and waterproof rugged computers have different levels of IP rating ranging from IP65 to even IP69K for submersible computing.
Thanks to the one-piece chassis and fanless design, rugged computers can reach a robust level of ingress protection rating. Briefly explained, IP rating has two digits, the first digit represents protection level from dust and the second digit represents protection against water exposure. The number 6 is the highest rating for dust protection which means the system is fully dust-tight and 9K is the highest rating for water exposure which means the system is fully protected against close-range, high-pressure, high-heat water jets.
4. Power Protection
Power protection is another feature that ensures the reliability and durability of a rugged computer. Thanks to the power protection feature, rugged computers can be deployed in environments that have power fluctuations. Some industrial deployments such as remote location applications or embedded systems can have high power fluctuations that can jeopardize the internal components of the computers.
Rugged computers are equipped with over-voltage protection (OVP), over-current protection (OCP), and a wide range of input capabilities to protect themselves from detrimental power fluctuations in unstable settings. OVP protects the system by automatically cutting off power input that is over 50 volts to avoid internal damage; And a wide range of input support various input voltages from 9 volts up to 48 volts of input to adapt with diverse configurations for different industrial power input environments.
5. Fanless Design
A Rugged computer cooling system utilizes a fanless design that implements passive cooling architecture to dissipate heat from the internal components. A fanless design carries huge benefits including lower MTBF (mean time between failure), lower power consumption, a low acoustic and silent system, shock & vibration resistance, dustproof, waterproof, and much more. Passive cooling utilizes ultra-conductive heatsinks that are made out of aluminum and copper heat pipes for efficient heat dissipations.
These heatsinks then transfer the heat from the hottest part of the components such as CPU, PCH (platform controller hub), and other processors to the external enclosure, dissipating the heat to the external environments. With a passive cooling design, a rugged computer can even leverage a powerful 65-watt CPU without any need for a fan in extended temperature ranges.
6. One-Piece Chassis
The One-Piece chassis is protecting the internal system while working as a giant heatsink for the rugged computer. The entire enclosure of a rugged computer is made out of heavy-duty metal that is molded into a one-piece design. Its one-piece designs help to eliminate fewer joints in the system design, providing better resistance to intense shock and vibration in the system. With fewer joint parts, gaps, and screws, the sealed enclosure can increase the IP rating level and its overall reliability.
7. Storage Solution: SSD vs HDD
Rugged computers are configured with solid-state drives or SSDs for their secondary storage solution. Using SSDs instead of traditional HDDs (hard disk drives) as secondary storage provides various benefits for rugged computers. Rugged computers do not use traditional HDDs to avoid damaging and corrupting data due to sudden movements Traditional HDDs use a high-rpm spinning platter which is a metallic disk that spins rapidly up to 15K rpm; the data is accessed through an actuator arm to read/write data onto the disk.
On the other hand, SSDs utilize NAND flash technology to read/write data without any moving parts, making SSDs eliminate s extremely durable and reliable for mission-critical industrial applications. SSDs also are extremely fast and compact, making them the clear choice for storage solutions when it comes to selecting storage options for rugged computers.
8. Industrial Grade Materials and Components
One of the elements that enable rugged computers to perform with better reliability and longevity is their industrial-grade materials. Every part of a rugged computer is made out of industrial-grade material for optimum durability, reliability, and longevity. The internal components from PCBs, power chokes, transistors, resistors, I/Os, and added components are carefully selected to meet industrial grade standards. Industrial-grade materials are the key to industrial-grade performances that ensure uptime and avoid downtime.
