What is the function of the SiS system on the computer?

SIS is the motherboard chip, the role of the control circuit!

Safety Instrumentation System (SIS); Also known as safety interlocking system.

It is mainly the alarm and interlocking part of the factory control system, which implements alarm action or adjustment or shutdown control for the results detected in the control system, which is an important part of the automatic control of the factory enterprise.

Peculiarity. 1. IEC61508 is used as the basic standard, which conforms to the safety standards of instruments stipulated by the International Safety Association.

2. It has wide coverage, high safety, and self-diagnosis function, which can detect and prevent potential dangers.

3. Fault-tolerant multiple redundancy system, SIS generally adopts multiple redundancy structure to improve the hardware fault margin of the system, and a single fault will not lead to the loss of SIS safety function.

4. The application is easy to modify, and the software can be modified according to actual needs.

5. The coverage rate of self-diagnosis is large, and the number of points that need to be checked during maintenance is relatively small.

6. The response speed is fast, the response time from the input change to the output change is generally about 10-50ms, and the response time of some small SISs is shorter.

7. It can realize the safety design of the whole circuit composed of sensors and actuators, and has monitoring functions such as short circuit and wire breakage.

SIS: SIS Systems, Safety Instrumented Systems.

SIS system (Safety Instrumented System) belongs to the automation of the production process of the enterprise, a set of systems used to ensure safe production, and the safety level is higher than that of the DCS automatic control system.

The SIS system is based on the distributed control system and adopts advanced, applicable and effective professional calculation methods to improve the reliability of the unit operation.

Extended closed-ruler data:

Peculiarity.

1. The SIS system must use independent sensors, logic standby group solvers and actuators (relative BPCS).

2. The SIS system only acts when a dangerous situation occurs, and usually does not act (problem: accidentally jumping out of the car).

3. The SIS system needs to be optimized between system complexity, maintenance costs, return on investment and safety level.

SIS refers to the safety instrumented system, which belongs to the category of enterprise production process automation, a set of systems used to ensure safe production, and the safety level is higher than that of DCS.

Automation refers to the process of achieving the expected goals through automatic detection, information processing, analysis and judgment, manipulation and control of machinery and equipment, systems or processes (production and management processes) without the direct participation of people or fewer people. Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and households. The use of automation technology can not only liberate people from heavy physical labor, part of mental labor and harsh and dangerous working environments, but also expand the function of human organs, greatly improve labor productivity, and enhance the ability of human beings to understand and transform the world.

Therefore, automation is an important condition and a significant symbol for the modernization of industry, agriculture, national defense, and science and technology.

Enterprise terminal image recognition system.

SI, corporate terminal image recognition, compared with the CI and VI design boom led by the implementation of brand strategy by large enterprise groups in China, SI is only for the implementation of chain enterprises and the implementation of store image design and management system.

SI (Space Identity): It is called space identification, store identity or interior identity, and it can also be regarded as an extension of VI, but the main purpose is to work in "three-dimensional space" and "decoration standardization".

The biggest difference between space recognition and traditional decoration design is that it is a systematic design, rather than a fixed-point design, so as to adapt to the problem of different sizes of each store when adapting to the development of the chain.

Hello, the SI system (Store Identity System), that is, the store image recognition system, generally includes the "store concept,

cultural and behavioural identification; Specialty store display system; Store publicity specifications" and other three parts.

The specification design of an SI system consists of several basic principles:

First, it should be consistent with the brand's concept identity (MI) and behavior recognition (BI);

Second, it is necessary to fully consider the adaptability of market positioning;

Third, it is necessary to take into account the multi-dimensional aspects of space, aesthetics, and consumer psychology;

Fourth, it is necessary to extend the application on the basis of the brand visual identity (VI).

The SI system must be coordinated with the VI system, and the store decoration, door head, and main color should strictly continue the specifications of the VI system, so as to effectively convey the brand message, so that consumers can understand the brand from multiple angles and uniformly, so as to promote product sales.

For example, the application of the logo should strictly implement the VI standard, the door head and the image wall need to have unity and continuity, and the auxiliary graphics should also be infiltrated and applied in the store decoration.
