Does anyone know what each part of the safety production guidance sign represents? Thanks!

GB2894-2008? Safety signs and guidelines for their use.

GBT2893.1-2004? Graphical symbols safety colors and safety signs, Part 1: Design principles for safety signs in workplaces and public areas. It consists of the word "ten" plus a "gear" The pattern is a symbol of safe production.

Red: conveys information about prohibition, stop, danger, or reminders about fire prevention and facilities; blue: conveys injunctive information that must comply with regulations; yellow: conveys information of attention and warning; green: conveys safety information Indicative information.

Safety signs are classified into four categories: prohibition signs, warning signs, instruction signs, prompt signs, and supplementary signs.

The meaning of prohibition signs is to prohibit or stop certain actions of people. The geometric shape of the prohibition sign is a circle with a slash, in which the circle is connected to the slash, in red, the graphic symbol is in black, and the background is in white.

Extended information:

The component distribution in the printed circuit board diagram is often very different from that in the schematic diagram. This is mainly because in the design of printed circuit boards, the main consideration is whether the distribution and connection of all components are reasonable, and many factors such as component volume, heat dissipation, anti-interference, anti-coupling, etc. must be considered. The printed circuit board designed based on these factors , it is difficult to be completely consistent with the schematic diagram from the outside;

But in fact, it can better realize the function of the circuit. With the development of science and technology, the production technology of printed circuit boards has made great progress; in addition to single panels and double panels, there are also multi-panels, which have been widely used in many fields such as daily life, industrial production, national defense construction, aerospace industry, etc. .

Among the four forms of circuit diagrams introduced above, the electrical schematic diagram is the most commonly used and the most important. If you can understand the schematic diagram, you will basically master the principles of the circuit, draw block diagrams, and design assembly drawings. , Printing board drawings are relatively easy. It is also very convenient to carry out electrical maintenance and design after mastering the schematic diagram. Therefore, the key is to master the schematic.
