Problems solved by technology

At present, many people use terminals directly, and a few people only use traditional earphones. In fact, traditional earphones have a permanent magnetic field of 1000 Gauss, and sometimes act as an antenna, which is more harmful to the human body.

Abstract

A security terminal machine comprises a housing, a base-band processing and logic control circuit, a man-machine interface, a shielding housing, a high-frequency head, a built-in antenna, a high-frequency socket, a high-frequency plug, an antenna switch, a single shielded antenna, a dual-shielded antenna, a shielded antenna with three antennas, and an exposed antenna. The security terminal machine is different from a conventional terminal machine in that: high-frequency radio frequency and intermediate frequency circuits of the high-frequency head of the security terminal machine and all circuits generating electromagnetic waves are shielded and isolated by a metal radome, and strong harm of electromagnetic fields to a human body is avoided; and only a display or touch screen is not shielded. According to the invention, a plurality of shielded antennas are arranged, the electromagnetic waves are guided to the position far away from the human body for exchanging signals with a ground station, so that the problems of strong harm to the human body and blind areas of the conventional terminal machine are solved; in addition, only by inserting the exposed antenna into the machine, the security terminal machine can be used as the conventional terminal machine, the usage is very convenient, and a good effect is achieved.

Description

technical field [0001] The present invention relates to a security terminal, and more particularly relates to providing a security terminal for direct use. Background technique [0002] The World Health Organization has published an article on May 31, 2011, electromagnetic waves are more harmful to the human body or cause brain cancer. After testing, the power density of electromagnetic waves emitted by existing terminals has far exceeded the GB9175-88 standard issued by the Ministry of Health, because existing terminals only move the antenna inside the machine. The effect after moving is very inconspicuous, and it cannot reach the above-mentioned GB9175-88 standard issued by the Ministry of Health at all. The power density of electromagnetic waves emitted by many terminals currently in production has been tested to reach 13600μw / cm2, which is 1,300 times higher than the GB9175-88 "Environmental Electromagnetic Wave Hygienic Standard" issued by the Ministry of Health. I ap...
