Introduction

Industrial control computer systems are widely used in industrial process measurement, monitoring and control, used in various fields has been extended.

Industrial control computer system, the main features of the "Encyclopedia of Computer Science and Technology" (second edition) which will be summarized as follows.

--- High reliability. requirements in the industrial field harsh environmental conditions (such as high temperature, low temperature, high humidity, dusty, corrosive gases, strong Under electromagnetic interference, etc.), still reliable continuous operation. Having a sufficiently long MTBF.

--- Easy maintenance. easy troubleshooting and maintenance on the system architecture. New generation of industrial control computer system with online maintenance function, Press the self-diagnostic results can be automatically cut off part of the fault may be faulty module or modules online hot plug replacement.

--- Strong real-time. a good real-time detection of input, data processing, communications, control and operation.

--- Easy Scalability. easily change control application program, the expansion of the number of control loops and functions.

This section GB/T 26802 is the industrial control computer system, general requirements, starting from the system as a whole, industrial control computer And various components of the system proposed regulatory requirements. When this part of the application GB/T 26802, and industrial control computer system requirements And provisions can be directly used in this section. The components of the industrial control computer system such as functional template module, industrial control computer substantially flat Station, bus interface, while also using industrial control computer system series of standards related standards relevant part.

1 Scope

This section GB/T 26802 specifies the functions of industrial control computer system design requirements, technical requirements, and system performance test Assessment methods, and inspection rules, marking, packaging, storage and acceptance. This section applies to industrial control computer system.
