Embedded industrial computer is a ruggedized enhanced industrial computer. The natural environment and temperature regulations of embedded industrial computers are relatively strict, and are generally customized according to the actual natural environment of customers. With the development of intelligent technology in industrial production, the electronic computer of embedded industrial control system has completed its role in various fields and industries.
The Difference Between to the Embedded Industrial Computer and Ordinary Industrial Computer
1. Introduction of embedded industrial computer
An embedded industrial computer is a ruggedized and enhanced industrial computer that can operate reliably in an industrial environment as an industrial controller.
As early as the early 1990s, the American AD company launched a similar industrial computer. Because of the reliable performance, fanless structure, small size and low price of embedded industrial computer, it is widely used in industrial computer.
2. Definition of embedded industrial computer
Embedded industrial computer, more fashionably called box computer or fanless industrial computer, embedded industrial computer is a compact computer specially designed for industrial sites.
Industrial personal computers often run in harsh environments and require higher data security. Therefore, industrial personal computers are usually specially designed for reinforcement, dust-proof, moisture-proof, corrosion-proof, and radiation-proof.
Industrial personal computers also have very high requirements for scalability, and the interface design needs to meet specific external devices. Therefore, in most cases, industrial personal computers need to be individually customized to meet the needs.
3. Technical characteristics of embedded industrial computer
3.1 The all-metal industrial chassis conforming to the "EIA" standard is adopted to enhance the anti-electromagnetic interference ability.
3.2 There is no fan in the chassis, and the heat dissipation depends on the chassis.
3.3 Equipped with a highly reliable industrial power supply, with overvoltage and overcurrent protection.
3.4 The power supply and keyboard are equipped with electronic lock switch, which can prevent illegal opening, closing and illegal keyboard input.
3.5 has self-diagnosis function.
3.6 There is a "watchdog" timer, which automatically resets without human intervention when it crashes due to a fault.
3.7 Facilitate the scheduling and operation of multitasking.
3.8 Features of embedded industrial computer:
Low power consumption fanless for use in harsh environments
3.9 Features of embedded industrial computer Use industry:
Low-power industrial computer application industry: can provide complete control and communication functions, ideal for automotive electronics, digital electronics/advertising sign (DSA), healthcare computers, gaming/game consoles, and aviation infotainment systems and other embedded industries.
4. The difference between embedded industrial computer and ordinary industrial computer
First of all, the location of the embedded industrial computer in the entire measurement and control system is often at the front end. The upward connection of the embedded industrial computer is often an ordinary industrial computer. The computing power, software resources, database support and other aspects of the ordinary industrial computer are embedded It is difficult to reach the industrial computer;
Secondly, in the construction of large-scale systems, the system expansion capabilities and network communication capabilities of ordinary industrial computers are also difficult to replace with embedded industrial computers;
In addition, in the fields of visual design, process monitoring, data statistics, scientific computing, prototype simulation design, and in-loop simulation, ordinary industrial computers have inherent advantages.
5. The working principle of the embedded industrial computer
The embedded industrial automation electronic computer is small in size, and the key hardware configuration of the industrial automation electronic computer is concentrated in the chassis, which occupies less indoor space and is easy to install and maintain. Basically, it can be placed in all mechanical equipment and control boxes.
The first case is a fully enclosed design with no cooling fan. The cooling surface of the CPU is coated with a layer of thermally conductive silicone. The thermally conductive silica gel is in direct contact with the heat sink of the chassis, and transfers the internal heat of the industrial computer to the heat sink, resulting in a reasonable heat dissipation without a cooling fan inside the chassis.
In fact, the embedded industrial computer is soundproof and anti-fouling, and the heat generated by the device itself is dissipated according to the fully enclosed aluminum alloy chassis. This can not only deal with the heat dissipation problem of the industrial computer, but also has the effect of anti-fouling and waterproofing.
Finally, the embedded industrial computer uses an embedded, low-power motherboard. Much of the hardware configuration of the device is integrated on the motherboard, thus preventing problems caused by various external connections.
