What is industrial control motherboard?

Industrial control motherboard is the motherboard used in industrial occasions, which is adopted by industrial computers. It can adapt to wide temperature environment, harsh environment, long-term high load work and so on.

According to the structure and size of industrial control motherboard, it can be divided into full-length card, half length card, 5.25 inch, 3.5 inch, PC104 architecture, etc.

According to the selected chip series: 386, 486, 586, PIII, P4, atom, etc. By chip type: x86 architecture, MIPs architecture, arm architecture, etc. There are also some parts customized according to customer needs.

The typical environment of industrial control motherboard is as follows:

Operating temperature: up to - 40 ℃ ~ 85 ℃;

Working humidity: the range can reach 0 ~ 95% of non condensation;

Environmental dust: metal dust and ordinary dust;

Electromagnetic radiation: strong electromagnetic interference environment, self radiation control;

Long term work: permanent start-up throughout the life cycle

Industrial computers can be used as home computers. Generally, there is no problem. But it is not suitable for video games. The main board of industrial computer is mainly stable, and it is started 24 hours a year. The memory is not ordinary, the stability is very good, and the error rate is almost zero. But the parts are expensive and the performance is not very fast.

What is embedded motherboard

Embedded industrial control computer is a single chip microcomputer control system integrated with industrial control workbench. The LCD screen with appropriate size is equipped to display the working menu, which can be connected to the standard keyboard, including characters, serial number, date and graphics, and can be connected to PC and other devices through RS232 serial port or USB interface; CF card interface can access 8m-2g CF card. Nandflash is used as stable storage; JTAG interface for debugging; There are also three panel buttons (confirm button, down button and return button) and an emergency stop button to control the operation independently. Support multi language menus, etc. Due to the use of high-performance processor and related peripheral hardware equipment, the data communication protocol of the system is more reliable, reasonable and easy to expand; Human computer interaction is more friendly and convenient; The system has high integration and small volume. The system can work independently as an embedded computer system. It can also be controlled by PC as a slave function device to complete more complex work. The system has three working modes: independent working mode, online working mode and maintenance working mode.

In the industrial all-in-one machine project, there are often occasions where the workpiece needs to move back and forth or accurately locate. It is easy to control these items with a stepping motor. Therefore, the embedded integrated industrial control machine with stepping motor is widely used as the control system of pneumatic processing, laser processing, automatic welding and other equipment. For example, marking machine is an electromechanical equipment that can print words and graphics on various metal or non-metal objects. The application of this system can greatly improve the speed and accuracy of marking; Another example is a laser processing machine tool, which cuts, punches and heat treats various parts by controlling the relative position between the laser beam and the workpiece. The system can give full play to the performance of ARM processor. It can improve precision and reduce production cost. It is an effective way to design new machine tools and transform old machine tools.
