System integration refers to the whole process of integrating hardware platform, network equipment, system software, tool software and corresponding application software into a large or giant information system with excellent performance and price ratio that is suitable for open environment and resource sharing according to the needs of applications .
System integration content:
1. From an information perspective, system integration should involve all stages of the information life cycle.
1. Information collection, processing, processing and storage;
2. Information transmission and transmission through various channels;
3. Use and consumption of information.
Second, look at system integration from a technical perspective.
1. Data processing technology;
2. Computer hardware and software platforms, including databases;
3. Multimedia transmission technology, local area network or wide area network;
4. Information restoration technology.
Safety technology to prevent the safety quality requirements of products and systems: high safety and electromagnetic compatibility
Product (system) security: It means that the product (system) can guarantee the human health and personal property safety of the user (user) during operation. The implementation of high safety standards is to ensure: protection against personal electric shock; protection against fire and overheating, protection against harmful rays and toxic gases; and protection against mechanical injuries.
Electromagnetic compatibility: refers to the coexistence state in which devices or systems can perform their respective functions together in a common electromagnetic environment. In layman's terms, it is necessary to solve the problems of electromagnetic interference and anti-electromagnetic interference.
A compound formed by the substitution of the hydroxyl group of a carboxylic acid (or amine) in the carboxylic acid, or the derivative of ammonia (or amine) with the substituted of the acyl group. Hydrogen bonds can form hydrogen bonds in the amino acid of amide, and the association between molecules can make the boiling point of amide be higher than the corresponding carboxylic acid. Amide is widely distributed in nature, protein is the amide bond â”€ CONH â”€ (or called a peptide bond) connected to the natural high molecular compound. The amide is heated for a long time in strong acid, which can be hydrolyzed to carboxylic acid and ammonia (or amines). The amide can be obtained from the partial loss of water or from the ammonia solution of acyl halide, acid anhydride and ester. Nitrile can be partially hydrolyzed and stopped in the amide phase.
Amide is mainly used as an industrial solvent, and the pharmaceutical industry is used to produce vitamins and hormones, as well as in the manufacture of insecticidal. In organic reaction, dimethylformamide is not only used as a solvent for reaction, but also an important intermediate for organic synthesis. Pesticide industry can be used to produce insecticidal.
