The traditional industrial computer uses a combination of 4U and other types of cold-rolled plate chassis + gold finger motherboard (full-length or half-length card) + base plate + high-power power supply.
There are a number of unstable elements to such a structure:
1. If the CPU card is inserted into the baseboard, there will be poor touch, such as oscillation, loose transportation process, gold finger oxidation, etc., which will lead to failure to boot.
2. Connect some ATX signal cables between the backboard and the CPU card.
3. The CPU card is powered by the backboard, and when the backplane presents a problem, it will affect the CPU card and cannot supply power normally, resulting in an unstable system (such as the unreasonable design of the baseboard power supply circuit); The CPU is an external interpolation (PGA package) method, and there is a danger in the connection, and the fan is required to dissipate heat, and the connection and service life of the fan and the CPU are the greatest safety risks.
4. The power consumption of the power supply is too large, and the power supply requires the fan to dissipate heat, which will cause damage to the power supply and the motherboard when the fan fails.
5. The structure of CPU card + base plate will bring trouble to the installation (at the time of flow consumption, the CPU card must be installed on the base plate), which will affect the operation efficiency and is not conducive to many installation operations.
The structure of the fanless industrial computer is a combination of all-aluminum shell + embedded motherboard + external low-power power supply.
Forte:
1. The shell of all-aluminum structure makes the heat dissipation more sufficient, small in size and light in weight. It is easy to carry with the device.
2. The advanced embedded, low-power CPU motherboard and the latest embedded technology are selected, and the related peripheral interfaces are integrated on the CPU motherboard, which reduces the connection problem and can avoid the related loosening problem.
3. The embedded CPU motherboard adopts a single +5V or +12V DC power supply method, and is equipped with a communication adapter to make the on-site power supply more abundant and more reliable.
4. Because the CPU of the embedded motherboard chooses the BGA (onboard) packaging method, there is no need to worry about the connection problem, and the fan-free design is selected, which greatly improves the reliability and completely solves the problem of insufficient heat dissipation and life of the traditional industrial computer.
5. When the customer's device is used, it only needs to use the external socket to connect the hard disk and memory, which shortens the installation time and improves the operation efficiency.
Summary: There are a lot of connection wires between the CPU card of the traditional industrial computer and the backplane or external interface, which leads to the problem of loose or wrong connection of the system, which brings the instability of the whole system (just like an electric fan in the system). The embedded industrial computer uses advanced skills to fundamentally deal with the problems that traditional industrial computers cannot handle, making the system more stable and the structure more refined.
