Embodiment 1

[0029] Embodiment 1 is a radiation position modulation communication system, which includes an information source, a control circuit, a signal generating device, a signal receiving device and a demodulation circuit arranged in sequence along the signal transmission direction. The signal generating device includes a radiation source and a base, and the radiation The source emits rays with strong penetrability, and there are multiple positioning positions on the base, and the radiation source is driven by the control circuit to switch between multiple positioning positions; the information source is used to convert the original information signal into the initial Electrical signal; the control circuit drives the radioactive source to move and switch between multiple positioning positions according to the initial electrical signal, and the radiation emitted by the radioactive source at different positioning positions forms a ray signal; the signal receiving device includes multiple...

Embodiment 2

[0033] Embodiment 2 is based on Embodiment 1, and a plurality of positioning positions are equally spaced on the base. A track is arranged between the multiple positioning positions, and the radioactive source moves between the multiple positioning positions along the track. The base can be a strip member, and multiple positioning positions are arranged sequentially on the strip member. The base can be a plate-shaped member, and a plurality of positioning positions are evenly distributed on the plate-shaped member. The base can also be a member of other shapes.

Embodiment 3

[0035] Embodiment 3 is based on Embodiment 1. The information source, control circuit and signal generating device are located on one side of the shielded space, and the signal receiving device and demodulation circuit are located on the other side of the shielded space. The communication system also includes an information receiving end, which is used for receiving the demodulated output signal.

[0036] When the information source, control circuit and signal generating device are located in the electromagnetic shielding environment, and the signal receiving device and demodulation circuit are located outside the electromagnetic shielding environment, the signal is transmitted and communicated from the electromagnetic shielding environment from the inside to the outside; when the information source, control circuit and signal generation The device is located outside the electromagnetic shielding environment, and when the signal receiving device and the demodulation circuit are...

Abstract

The invention discloses a ray position modulation communication system and a communication method, the ray position modulation communication system comprises an information source, a regulation and control circuit, a signal generation device, a signal receiving device and a demodulation circuit which are sequentially arranged along a signal transmission direction, the signal generation device comprises a radioactive source and a base, and the radioactive source emits rays with strong penetrability, wherein a plurality of positioning positions are arranged on the base, and the radioactive source is driven by the regulation and control circuit to be switched among the plurality of positioning positions; according to the initial electric signal, the radioactive source is driven to move and switch among a plurality of positioning positions, and rays emitted by the radioactive source at different positioning positions form ray signals; the signal receiving device comprises a plurality of ray detectors which are in one-to-one correspondence with the positioning positions in the ray transmission direction, receive ray signals, convert the ray signals into coded electric signals, demodulate the coded electric signals and then output the coded electric signals. According to the invention, based on ray position coding, code element types are more, the communication rate is improved, andthe communication error rate is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radiation position modulation communication system and a communication method. Background technique [0002] Gamma-ray communication is a communication method in which gamma-ray photons are used as carrier signals to transmit information. Gamma rays have strong penetrating power and high energy. They are electromagnetic waves with a wavelength shorter than 0.01 angstroms and a frequency higher than 1.5 trillion hertz. Due to their extremely high penetrating power, using gamma rays for communication is very important for communication in electromagnetic shielding environments is of great significance. [0003] The gamma-ray carrier frequency is very high and has particle characteristics, which are reflected on the gamma-ray detector 1, and the gamma-ray photons are characterized as discrete pulse trains in time, which has the time resolution capability of the existing gam...
