Background
The signal shielding of the common circuit is to install a shielding case on a PCB circuit board and weld components with electromagnetic radiation in the shielding case, thereby reducing the influence of the electromagnetic radiation on the surrounding environment. The method can only weaken the electromagnetic radiation and can not achieve the effect of completely eliminating the electromagnetic radiation.
Two methods of electromagnetic shielding: signal interference, signal absorption. The signal interference is an interference signal which transmits the same frequency, so that signals around the frequency band cannot normally communicate. The signal absorption is to absorb the surrounding electromagnetic wave with special material, and convert the electromagnetic wave into other energy to be released.
In examination rooms, party administration institutions and military office buildings, a signal interference mode is generally used, and sensitive information is prevented from being divulged through communication means such as mobile phones. Signal interference can interfere with all communication signals of a certain frequency band, and is not suitable for the requirement of Bluetooth directional configuration. The signal absorption can block the outside useless Bluetooth signals and can be used for Bluetooth directional configuration.
In the process of transmitting electromagnetic waves, when the electromagnetic waves encounter a metal material, the electromagnetic waves cannot penetrate through the metal material, and then the electromagnetic waves are transmitted along the metal material, so that heat is generated in the process of transmitting the electromagnetic waves, and the energy of the electromagnetic waves is consumed. And the metal shell is used for manufacturing the shielding cover, so that a process gap exists, the signal shielding effect is not good, and the signal shielding effect is enhanced by combining other modes. When the frequency of the electromagnetic field is high, eddy current is generated by utilizing the low resistivity of the metal material, so that the effect of offsetting electromagnetic waves externally is formed, and the shielding effect is achieved.
The existing signal shielding device has the following defects:
A. the shielding bag is used for solving the problem of Bluetooth directional configuration, and the effect is poor;
B. the function is simple, the upper computer can not be used for operating configuration parameters and configuration results, a human-computer interaction link is lacked, and an LCD display screen and a matrix keyboard are not available.
