What does the system integration project include

1. Data and information integration Data and information integration are based on hardware integration and software integration, which is the core of system integration. The main problems that usually need to be solved include: reasonable planning Based on information, reduce data redundancy, realize information sharing more effectively and ensure the security and confidentiality of data and information.

2. Technical integration ability: technical integration ability, that is, the ability to provide corresponding system models for customer needs from the perspective of the system, and the ability to realize specific technical solutions and operation plans of the system model.

3. Broadly speaking, system integration includes personnel integration, organization integration, equipment integration, system software integration, application software integration and management methods integration and other aspects.In a narrow sense, system integration is the integration of the system platform.

4. Then, the third content of system integration technology is system testing. In the system testing stage, testers need to conduct a comprehensive test of the system, including functional testing, performance testing, security testing, etc. Testers need to write test cases, implement test plans, and record and analyze test results.

What is the work content of system integration?

The first content of system integration technology is system design. In the system design stage, it is necessary to determine the functional modules, data processes and interface design of the system according to user needs and business processes and other requirements.

System integration refers to the integration of equipment and information in an organization, and the support for applications through a complete system.System integration includes equipment system integration and application system integration. Five elements included in system integration: (1) Customer industry knowledge.

System integration engineers need to complete the configuration, maintenance and inspection of on-site servers, storage and related software. The following is the job content of the system integration engineer position I have sorted out.

The specific work content (daily work) of the system integration engineer is to pull the network cable, move the equipment, and upgrade the equipment. A company buys new equipment, but the company's network management technical ability is uneven. In many cases, it is impossible to deal with new equipment. Some companies will recruit some network managers with strong technical ability to deal with these equipment, but the cost will increase a lot.

Classification of grounding systems

The analysis is as follows: High current grounding and small current grounding are both grounded by neutral points in the power system, and they are distinguished according to the main operating characteristics. The small grounding current system is also known as the ineffective grounding system. Including neutral point non-grounding, extinguishing arc coil grounding, and high-impedance grounding system.

According to various protection methods and terminology concepts stipulated by IEC, low-voltage power distribution systems are divided into three categories according to different grounding methods, namely TT, TN and IT systems, which are described as follows. (1) TT method power supply system TT method refers to the protection system that directly grounds the metal shell of electrical equipment, which is called the protective grounding system, also known as TT system.

Grounding refers to the neutral point of the power system and electrical device, the exposed conductive part of the electrical equipment and the conductive part outside the device connected to the earth through the conductor. It can be divided into working grounding, lightning protection grounding and protective grounding.

Working grounding: Grounding is carried out in order to provide a zero potential point for the neutral point of the entire three-phase AC power grid, such as transformer neutral point grounding.

JaneThere are three main types of construction electrical protection grounding: TT grounding system, TN grounding system and IT grounding system. In-depth analysis: Construction electrical safety is an important part of the construction process. The adoption of a suitable grounding system plays a crucial role in ensuring the safety of construction personnel and equipment.

Power system grounding can be divided into the following categories: Power system grounding refers to the process of connecting the non-electrical parts of metal parts or equipment in the power system to the earth. The main purpose of the grounding system is to ensure the safe operation of the power system and protect personnel and equipment from electric shock and overvoltage.
