industrial automation is becoming more and more popular.computers are being used as industrial controls in various processes in all walks of life, such as GPS vehicle and ship navigation systems, highway overspeed camera systems, wireless transmission of remote video surveillance signals, set-top boxes and other industries and fields.

at present, most similar products on the market use a P IV processor, with the lowest power consumption of 65W for the processor and over 100W for the motherboard.a dedicated P IV CPU fan must be installed to meet the overall cooling requirements of the motherboard. When the system runs for a long time, CPU fan 1 once the transfer is stopped, the CPU and motherboard will be damaged destructively. Moreover, the software and hardware used in various industries are different, and the number is also more or less.There are only two PCI slots for mainboards commonly sold in the market, which cannot meet the increasing technological needs.

the invention aim of this article can be solved by the following technical scheme.

a fan-free industrial computer device, which comprises an embedded mainboard, a processor, a adapter card, onboard memory, a hard disk, a data line and a chassis; Among them, the embedded motherboard includes a 184pinDDR memory slot, a PC104 plus slot, a MINIPCI slot, and four strings port, a parallel port, 16bit digital I0 interface and USB, COM, PRT and other expansion interfaces; It is characterized in that:a, the embedded mainboard is directly welded with 479-pin processor; The radiating fin is closely attached to the processor through radiating grease; The hard disk is connected to ; The onboard memory is connected to the 184-pin memory slot of the embedded motherboard. The combined mechanism is fixedly connected with the chassis through screws; B, the embedded motherboard is also provided with a PP2P3 board through the stabilizer, and one PCI slot is plugged with a adapter card, which is perpendicular to the PP2P3 board, and the sockets of the three PCI slots on the adapter card are parallel to the PP2P3 board.

the embedded motherboard is the motherboard of desktop chipset 845GV.

the onboard processor is the mobile Intel⑧ULV Celeron M processor.

MINIPCI slot can be connected with wireless network card.for complex buildings and terrain where transmission cables cannot be laid, wireless network can be established to effectively and quickly connect various information points.

embedded motherboard integrates three network cards, supports 10M-100M-1000M network, and is suitable for network firewall, network server and other products.

a fan-free industrial computer device designed by the technical scheme in this paper, on the one hand, uses a low-priced desktop Intel⑧845GV chipset, which is about 25 us dollars lower than the mobile chipset 852GM/855GME, while the difference in function is very small , reducing costs; On the other hand, due to the combination of high-performance and low-power mobile board-mounted processors, the power consumption of the mainboard is less than 10W when running at full speed, only the heat sink is required to dissipate heat passively, and no additional heat dissipation fan is required to avoid fan stalling system failure due to poor heat; The combination of the two makes the product find a perfect balance between performance and price.

in addition, PCI slots are added to the adapter card of its device to meet the functional requirements of special industries.
