The industrial tablet computer uses a plastic or all-aluminum panel and an embedded motherboard. The advanced and sturdy mechanism design can withstand the extreme environments of shock, vibration, humidity, and high and low temperatures. System advantages:

(1) For customers, they only need to use the external socket to connect the hard disk and memory during installation, which can be used, which shortens the installation time and improves the work efficiency;

(2) The embedded CPU motherboard adopts single +12V-- +24V DC power supply mode, and is equipped with an AC adapter, which makes the field power supply mode more abundant and the power supply more reliable;

(3) The use of advanced embedded, low-power CPU motherboard and the latest embedded technology, and related peripheral interfaces are integrated on the CPU motherboard, reducing connection problems and avoiding related loosening problems.

(4) Because the CPU of the embedded motherboard adopts the BGA packaging method, there is no need to worry about connection problems, and the fan-free design greatly improves the reliability and completely solves the problem of insufficient heat dissipation and lifespan of traditional industrial computers.

(5) The shell of all-aluminum structure makes the heat dissipation more sufficient, small size and light weight. Easy to install and carry.

(6) The fanless embedded industrial computer uses an all-aluminum panel and an embedded motherboard. The advanced and sturdy mechanism design can withstand the extreme environments of shock, vibration, humidity, and high and low temperatures.

From the above differences, it can be seen that there are a large number of connection lines between the CPU card and the backplane or external interface, which leads to the loose or wrong connection of the system and the instability of the entire system; the embedded industrial panel computer adopts advanced technology, It fundamentally solves the problems that cannot be solved by traditional industrial computer, making the system more stable and the structure more sophisticated. The following is the difference in the functions of the industrial computer. The CPU card drives the related interface card on the passive backplane in the traditional industrial computer, which has hidden dangers:

(1) The capacity monitoring problem exists due to the bridge chip on the bottom board.

(2) Because the peripheral card needs to be inserted on the passive backplane, sometimes it is unable to drive more peripheral cards due to the influence of the main board's driving ability.

(3) The signal wiring between the CPU card and related peripheral cards is long, and there is signal attenuation and interference.

(4) The traditional industrial computer has no reserved interface for more advanced peripherals.

An industrial computer is one that is designed for use in industry, which is to say the production of goods, manufacture of machinery, or processing of raw materials. As such, they have many unique benefits over the average consumer desktop. When designing for these applications, it is important to build the computers to be able to withstand all of the environmental factors involved and still provide all of the functionality required. Environmental factors can include such things as dust, vibration, temperature variation, etc.

Since these design requirements result in a very sturdy, reliable PC, industrial computers have been adopted for use in many other industries and applications such as digital signage, robotics, and outdoor use-cases. As a result, the term industrial computer has become a sort of catch-all term in a lot of marketing for any system that approximates these specifications, even if it’s not specifically targeted towards the industrial automation/manufacturing industry. Because of the wide range of needs, industrial computers can be found with incredibly efficient low-power processors like Atoms and Celerons, all the way up to high powered i7s or even Xeons.

1. Durability

Industrial computers are expected to work in harsh conditions. Whether it is powering an outdoor kiosk contending with wind, heat and cold, or it is on the factory floor having to contend with dust and vibration, an industrial computer is going to have to carry on functioning. As opposed to brittle consumer computer products which are designed to sit on a desk in a climate controlled environment, industrial computers are designed from the beginning with these environmental considerations in mind. Where a consumer pc would overheat, an industrial PC would be populated with extended temp rated components and with a chassis intelligently designed as a heat-sink to “wick” the heat off the internals and into the air. In the face of shock or vibration, where a consumer PC would literally fall apart or at least sustain damage to brittle internal components, an industrial PC would be constructed with a sturdy metal chassis, mounted onto a surface in such a way as to reduce vibration and with internal components mounted such that they receive less shock.

2. Reliability

Industrial computers are often installed into applications where the operating time is 24/7. This is a great deal more usage than the average consumer application, which is approximately 5-8 hours a day, in an office setting. To make things even more difficult, computers in these applications can sometimes be installed in locations that are hard to access for maintenance, making reliability that much more important.
To address these requirements, industrial computers are constructed with components which are suitable for continuous operation. SSDs or other flash storage are favored over HDDs for instance, because the spinning disk within an HDD is a potential point of failure. For this same reason, industrial computers are built to be fanless. They don’t even have a CPU fan! In addition to bringing a lot of unwanted dust inside the computer, fans can be a major point of failure within a computer. If any one fan fails, that can cause the computer to overheat, shut down and potentially damage some of the much more expensive components within the computer. The ideal industrial computer has no moving parts within it.

3. Power Requirements

While many applications and equipment call for specific voltages such as 9V, 12V or 24V, there is a difference between the nominal voltage and what the machine actually receives. As many power sources are unregulated, a varying voltage can damage the computer which is on the receiving end. To combat this problem, many industrial computers have a wide range voltage input (such as 9~48V) which protects the device, without having to invest in more expensive protection circuitry. In addition to this, industrial computers have access to many other power options, such as POE, Wake on Lan, and even Power on Ignition for in-vehicle applications.

4. Customization

Because no 2 applications are truly the same, it follows that there isn’t one computer that will fit every application. For this reason, many industrial computers are offered to be configurable and modular. Having the ability to choose different I/O and components for the computer system to have right out of the box enables industrial computers to fit a very wide range of requirements. Additionally, if the configuration options offered by on-the-market industrial computers still don’t fulfill the requirements, there is the additional option of purchasing a customized or even custom-designed computer, in order to get that perfect fit. Traditional commercial computers have many features designed to meet the needs of general consumers, however, industrial computers can be customized for very specific functions related to Telecom, Kiosk, Medical Imaging, and Broadcast to name a few.
