What are the functions of a shielded room?
2023-03-06
With the rapid development of technology, more and more people are using electronic components and products related to electromagnetic waves. This not only generates interference phenomena, indicating that the received signals are interfered with, but also plays an important role in shielding equipment. Electromagnetic shielding rooms will eliminate these phenomena. Electromagnetic shielding rooms are a method of limiting electromagnetic waves to a certain area through shielding bodies such as metal shells, boxes, and plates. So what are the functions of a shielded room?
1. Block the diffusion of indoor electromagnetic radiation to the outside world. Strong electromagnetic radiation sources should be shielded and isolated to prevent interference with the normal operation of other electronic and electrical equipment and even damage to the health of workers.
2. The shielding room isolates external electromagnetic interference to ensure the normal operation of indoor electronic and electrical equipment. Especially in the measurement and testing of electronic components and electrical equipment, using electromagnetic shielding rooms (or darkrooms) to simulate ideal electromagnetic environments can improve the accuracy of detection results.
3. Prevent information leakage from electronic communication devices and ensure information security. Electronic communication signals will propagate to the outside world in the form of electromagnetic radiation (EMPEST phenomenon), and the enemy can intercept and restore them using monitoring equipment. Electromagnetic shielding room is an effective measure to ensure information security.
4. The military command communication elements must have the ability to resist enemy electromagnetic interference. In extreme situations such as electromagnetic interference attacks or even nuclear explosions, they must be combined with other protective elements to protect electronic communication equipment from damage and ensure normal operation. The electromagnetic pulse protection room is a special product developed based on the electromagnetic shielding room and combined with the special requirements of electromagnetic pulse protection in the military field.
