Industrial personal computer and industrial personal computer communication protection method

Abstract

The invention provides an industrial personal computer and an industrial personal computer communication protection method. The industrial personal computer comprises a main control module, a power module and a communication module. The main control module is connected with at least one peripheral device interface through the communication module. Each peripheral device interface is connected witha peripheral device. The peripheral devices communicate through the communication module. The main control module, the communication module and the peripheral devices are powered by the power module.During communication among the main control module, the communication module and the peripheral devices, when a data sender sends a data packet, serial number, source address and destination addressinformation is added to the data packet, and the check value of the data packet is calculated; the data sender packages and sends the information; and a receiver checks whether the source address andthe destination address of the data packet are correct or not after receiving the data packet. According to the industrial personal computer, an X86 architecture processor serves as a core, communication between the industrial personal computer and different peripheral function boards is achieved by expanding the number and types of high-speed buses output by a system board, and the purpose of function expansion is achieved.

Description

technical field [0001] The invention belongs to the field of industrial control, and in particular relates to an industrial computer and a communication protection method for the industrial computer. Background technique [0002] Industrial computer is a kind of industrial equipment that adopts computer bus to realize resource expansion and control. It is mainly used in industrial automation control system. The industrial computer platform generally uses a high-speed bus to connect different functional modules to realize the expansion of peripheral resources. The internal bus architecture of different industrial computers is different, such as the CPCI industrial computer that supports the PCI bus, and the PXIe / CPCIe industrial computer that supports the PCI / PCIe hybrid bus. etc. Different specifications have different requirements for the definition of the communication interface between boards / modules and control signals. [0003] Most of the industrial computer products ...

AI Technical Summary

Problems solved by technology

[0004] 1) Existing industrial computers generally strictly follow their own standards and specifications to meet the versatility and compatibility of each slot, but it also results in the limitations of a single internal bus and poor interface scalability

[0005] 2) Existing industrial computers are system motherboards / modules that communicate with each peripheral through a high-speed bus, but cannot directly communicate with each other

[0006] 3) In the existing industrial computer, the input power supply is connected to the power plug-in through the cable, and the cooling fan is connected to the motherboard control interface through the cable. The cable connection not only results in low production efficiency, but also is very inconvenient for later on-site maintenance.

[0007] 4) The design of the heat dissipation air duct of the existing industrial computer is unreasonable. Some air duct air inlets are only designed at the bottom of the chassis. When the equipment is installed on the rack in the cabinet, the air inlet is easily blocked by other equipment; At the front of the chassis, the fan exhaust volume is small, which makes the internal heat dissipation unsatisfactory.

[0008] 5) Existing industrial computers generally use ATX power supply for power supply, but the ATX power supply is not only bulky and takes up space, but also the output power of the ATX power supply needs to be connected to the corresponding connector through a cable, which is inconvenient for installation and maintenance

[0009] 6) The existing industrial computer uses an ATX power supply. In order to reduce the operating temperature of the power supply, the power supply comes with a cooling fan. The noise of the fan is relatively large, which will increase the overall noise of the system.

[0010] 7) The performance configuration of the main board of the existing industrial computer is generally a fixed configuration. When the demand changes and requires high performance, it is necessary to re-select the model. When the demand changes and requires low performance, it will cause waste of resources

[0011] 8) The internal modular design rate of the existing industrial computer is low, and most of the key chips are directly surface-mounted on their respective carrier boards. Once a faulty chip is damaged, maintenance is inconvenient, and the entire board may be scrapped
