Who knows the meaning of each part in the safety production guidance sign? thank you

GB2894-2008？ Safety signs and their use guide.

GBT2893. 1-2004？ Graphical symbols. Safety colors and safety signs. Part 1: design principles of safety signs in workplaces and public areas. The pattern consisting of "ten" and "gear" is a sign of safe production.

Red: transmitting information of prohibition, stop, danger or prompting fire prevention and facilities; Blue: transmitting mandatory information that must comply with laws and regulations; Yellow: information that conveys attention and warning; Green: Send security information.

Safety signs are divided into four categories: prohibition signs, warning signs, indicating signs, prompting signs and supplementary signs.

The prohibition sign means to prohibit or stop certain behaviors of people. The geometric figure of the prohibition sign is a circle with diagonal lines, in which the circle is connected with diagonal lines and is red, the graphic symbol is black and the background is white.

Extended data:

The component distribution of printed circuit board diagram is often very different from that of schematic diagram. This is mainly because in the design of printed circuit board, whether the distribution and connection of all components are reasonable depends on many factors such as component volume, heat dissipation, anti-interference and anti-coupling. The printed circuit board designed by combining these factors is difficult to be completely consistent with the schematic diagram in appearance;

In fact, it can better realize the function of the circuit. With the development of science and technology, the manufacturing technology of printed circuit board has made great progress; In addition to single and double panels, there are many panels, which have been widely used in daily life, industrial production, national defense construction, aerospace and many other fields.

Among the four circuit diagram forms introduced above, the electrical schematic diagram is the most commonly used and important. If you can read the schematic diagram, you can basically grasp the principle of the circuit, draw the block diagram, design the assembly diagram and print the board diagram, which is relatively easy. It is also very convenient to master the schematic diagram and carry out the maintenance and design of electrical appliances. Therefore, the key is to master the schematic diagram.
