01 introduction
in the industrial field, various devices often need to face severe electromagnetic interference. in order to cope with the increasingly complex electromagnetic environment, hanzhen 3d cameras are designed from the source and pay great attention to the emc performance of the products. the new products developed must be checked and checked one by one, and then tested and certified by professional certification agencies. currently, all the 3d camera products launched have obtained the relevant electromagnetic compatibility certification of the industry.
02 what is emc
electromagnetic compatibility (emc) terminology explanation: the ability of a device or system to work normally in its electromagnetic environment, and does not constitute unbearable electromagnetic disturbance to anything in the environment. (refer to gb/t4765-1995)
from the above concepts, three elements of emc can be sorted out: emi, ems, and electromagnetic environment.
2.1 emi
emi (electro magnetic interference, electromagnetic interference), that is, the equipment or system in a certain environment, during normal operation, should not generate electromagnetic energy that exceeds the requirements of the corresponding standards.
2.2 ems
ems (electro magnetic susceptibility, electromagnetic immunity) refers to a device or system in a certain environment. during normal operation, the device or system can withstand electromagnetic energy interference within the range specified by the corresponding standard.
2.3 electromagnetic environment
electromagnetic environment, that is, all kinds of electrical and electronic equipment that use electrical energy to work, together with the power supply of the equipment, the load, other electrical and electronic equipment around, the equipment operator or the person providing services for the equipment, and even other living substances, the specific working environment formed.
