Electromagnetic shielding room and communication system

Abstract

The invention provides an electromagnetic shielding room and a communication system, and the electromagnetic shielding room comprises a shielding room housing and an LIFI module used for optical communication. The LIFI module is arranged in the shielding chamber shell and comprises a metal shell, a communication optical fiber, an optical transceiver and a power supply unit for supplying power to the optical transceiver; the optical transceiver is arranged in the metal shell and is connected with one end of the communication optical fiber; the other end of the communication optical fiber passes through the metal shell and extends to the outside of the shielding chamber shell; the power supply unit is arranged in the metal shell and is electrically connected with the optical transceiver; and a waveguide window is arranged at the position, corresponding to the optical transceiver, of the metal shell and used for transmitting light emitted and received by the optical transceiver. Therefore, communication requirements in a shielding scene can be expanded based on LIFI communication, and compared with a wired communication mode, the LIFI communication is wireless communication, so that the convenience and the practicability are higher, and the communication experience of a user is further improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an electromagnetic shielding room and a communication system. Background technique [0002] At present, the electromagnetic environment in life is relatively complex, and equipment is more susceptible to interference from various external signals and / or internal signal leakage. For some precision instruments and equipment, the use is affected due to various interferences from external signals, and the test results obtained are not accurate. Therefore, most of the testing of instruments and equipment needs to be carried out in electromagnetic shielding rooms to obtain accurate Test Results. [0003] However, when testing in an electromagnetic shielding room, the tester is isolated from the outside world and cannot communicate with the outside world. The reason is that the current communication methods, such as cellular (Cellular) communication, Wireless Fideli...

Problems solved by technology

However, the way the user opens the door of the shielding room, the device will still be interfered by external signals, and the way of wired communication is less convenient and practical
