The numbering rules of the integrated wiring system identification in the system.

Code definition of integrated wiring identification (describe how the identification of the integrated wiring system is defined, which parts the identification consists of, and the meaning of each part.) 2 Numbering rules of twisted pair and information points (describe the numbering rules of the integrated wiring system identification in this system.

The basic structure of the integrated wiring system is star-shaped. According to the GB 50311 standard, the integrated wiring system can be divided into seven subsystems: work area subsystem, wiring (horizontal) subsystem, trunk (vertical) subsystem, equipment-to-to-equip subsystem, in-line subsystem, management subsystem, construction Build a group subsystem.

The transparent tail should be long enough to wrap the cable in a circle and a half. V. Should doUse the identification (i) Cable identification TIA/EIA-606 2 Cable identification level and trunk subsystem cable should be marked at each end. It is recommended to stick labels on each end of the cable rather than just marking the cable.

As for how to make the logo, it depends on the actual situation. For example, the first information point on one layer can be marked as 1F-1D, and the voice point can be marked as 1F-1V. I hope it will be helpful to you.

What system identifiers are there in c language

1. The identifiers in c language are composed of letters (A-Z, a-z), numbers (0-9), underscores "_ "Composed, and the first character cannot be a number, but can be a letter or an underline. For example, the correct identifiers: abc, a1, prog_to.

2, sore, number1student_name, etc. are all correct identifiers; 8times, price/tea, low! Valume and so on are all incorrect identifiers.

3. The legitimate identifiers in the c language are: identifiers can be composed of letters, numbers and underscores.Among them, the first character of the identifier must be a letter or an underline. The identifier cannot be a C language keyword.

4. Keywords, also known as reserved words, are some words with fixed meanings pre-prescribed in C language, such as int and return in the first program of C language. Users can only use them according to predetermined meanings and cannot change their meanings without permission.

Urban logo of the logo system

How to design the identification system

1. Therefore, the cultural background should be fully considered when designing the campus environment identification system.The design of the campus environmental identification system should be scientific and forward-looking, reflecting the characteristics of modern, information, gardening and ecological campus.

2. The materials and processes of making the signboard of the visual guide system in tourist attractions should be environmentally friendly and green. In the selection of the installation location, we should also avoid destroying the natural environment of the scenic spot as much as possible. 4 With the development of science and technology, the scenic spot logo guide has also shown an intelligent trend. This is also a new trend in the development of the entire logo visual guidance system industry.

3. Visual basic element design, preparation for visual application element design, development of specific application design projects, preparation of VI visual recognition manual, visual basic element design, enterprise logo, which can be divided into enterprise's own logo and commodity logo. Characteristics of enterprise logo: First, recognition. Second, systematic.

4. The first modeling. After determining the point of the signboard, the modeling design can be developed. The modeling should be set according to the characteristics of the school, especially when designing the logo system of kindergartens, primary schools and other schools, the safety of students should be put first. The bulletin board.

5. Creative community identification system design methods and skills: Identification is the external form and structure of the internal visual guidance system of the community. It is an important carrier for visual guidance indication, identification and display space, and the most intuitive visual image in the community. The identification system is to encode various environmental information inside the community with the latest and most intuitive visual recognition.
