Embodiment 1

[0035] Embodiment 1 is a gamma ray communication system, such as figure 1 with figure 2 As shown, it includes an information source, a modulation circuit 3, a gamma ray emitting device, a gamma ray detector 2 and a demodulation circuit 4 arranged in sequence along the signal transmission direction, the gamma ray emitting device emits gamma rays, and the gamma ray emitting device includes a radiation source 1 and the shielding shell 5 that wraps the radiation source, the shielding shell 5 is provided with a ray through hole 7; when the gamma ray emitting device emits gamma rays, the gamma ray passes through the ray through hole 7; when the gamma ray emitting device does not emit gamma rays When raying, gamma rays are shielded. The information source converts the information signal into an input electrical signal; the modulation circuit 3 controls the gamma ray to pass through the ray through hole 7 or is shielded according to the input electrical signal to form a gamma ray si...

Embodiment 2

[0039] Embodiment 2 is based on Embodiment 1. The shielding case 5 moves relative to the radiation source 1 , so that the gamma rays pass through the radiation hole 7 or are shielded by the shielding case 5 . The radioactive source emits γ-rays by changing the spatial position of the radioactive source, and the radioactive source does not emit γ-rays by physically shielding the radioactive source with a shielding case.

[0040] There are two ways for the shielding shell to move relative to the radioactive source. One way is that the radioactive source remains stationary, and the shielding shell 5 is connected to the modulation circuit 3. The modulation circuit controls and drives the shielding shell according to the input electrical signal, so that the shielding shell is relatively The radiation source moves, and at the same time, the gamma rays may pass through the radiation hole and may be shielded by the shielding shell, so that the gamma ray signal is encoded by on / off of t...

Embodiment 3

[0042] Embodiment 3 is based on Embodiment 1. A shielding cover is provided on the ray passing hole 7, and the shielding cover is movably connected with the shielding shell 5. When the shielding cover moves relative to the ray passing hole 7, the gamma rays can pass through. Pass through the ray through hole 7 or be shielded by the shielding cover.

[0043]In the specific implementation process of Embodiment 3, there are two connection methods between the shielding cover and the ray through hole. One connection method is to connect the shielding shell to any edge position of the shielding cover at a position close to the ray through hole. During the movement of the shielding cover around the axis, when the shielding cover does not cover the ray passing hole, the γ-ray passes through the ray passing hole, and when the shielding cover covers the ray passing hole, the γ-ray is shielded by the shielding cover and passes through the ray passing hole. The on / off of the gamma ray rea...

Abstract

The invention discloses a gamma-ray communication system and a gamma-ray communication method, the gamma-ray communication system comprises an information source, a modulation circuit, a gamma-ray emitting device, a gamma-ray shielding body, a gamma-ray detector and a demodulation circuit which are sequentially arranged along a signal transmission direction, the gamma-ray emitting device comprisesa radioactive source, and the radioactive source emits gamma rays; the information source converts the information signal into an input electric signal; the modulation circuit controls the gamma rayto be shielded or not shielded by the gamma ray shielding body according to the input electric signal to form a gamma ray signal; the gamma-ray detector receives the gamma-ray signal and converts thegamma-ray signal into an output electric signal; the demodulation circuit receives the output electric signal, demodulates the output electric signal and outputs the demodulated output electric signal. According to the invention, gamma rays are used for communication; the electromagnetic wave frequency range capable of being used for communication is expanded; and a new technical means is providedfor solving the communication problem in the electromagnetic shielding environment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a gamma ray communication system and a communication method. Background technique [0002] Electromagnetic waves are oscillating particle waves derived from the same and mutually perpendicular electric and magnetic fields in space. They are electromagnetic fields that propagate in the form of waves and have wave-particle duality. [0003] In 1887, Hertz obtained through experiments that electromagnetic energy can be transmitted across space, which led to the birth of radio and was also the origin of the entire mobile communication. Since then, wireless telegraph communication, radio communication, microwave communication, and laser communication have appeared one after another. In 2007, Dr. Keith Gendreau, an astrophysicist at NASA's Goddard Space Flight Center, proposed the concept of X-ray communication and obtained preliminary results. Communication verification. Among...
