Embodiment 1

[0016] Such as figure 1 , the radio transmitting station used in the long-distance tunnel is composed of a signal source generator 3, a high power amplifier 2, and a transmitting antenna 1.

[0017] The signal source generator 3 and the high power amplifier 2 are placed inside the cabin body 4 of the transmitting station.

[0018] The signal source generator 3 is placed under the high-power amplifier 2, and is connected with the information circuit of the high-power amplifier 2, and transmits the generated digital signal to the high-power amplifier 2, which converts the signal into an ultra-long wave after being processed by the amplifier.

[0019] The transmitting antenna 1 is connected to the high power amplifier 2 to transmit the ultra-long wave processed by the amplifier. Utilize the principle of ultra-long wave penetrating power to directly communicate with the receiver in the tunnel. It solves the disadvantages of wired communication and reduces the capital investment...

Abstract

The invention relates to a wireless transmission station for a long-distance tunnel. The wireless transmission station comprises a signal source generator 3, a high-power amplifier 2 and a transmission antenna 1. The signal source generator 3 and the high-power amplifier 2 are arranged inside a transmission station cabin. The signal source generator 3 is mutually connected with an information circuit of the high-power amplifier 2, and the transmission antenna 1 is mutually connected with the high-power amplifier 2. By means of the principle that the penetrating power of super long waves is strong, the smooth communication in the tunnel is ensured, the defects of wired communication are solved and the laying investment is reduced.

Description

technical field [0001] The invention relates to a radio transmission station used in a tunnel to emit ultra-long waves for communication through rock formations. Background technique [0002] Due to the geological structure, the signal in the tunnel is not good, especially in some long-distance tunnels, the signal cannot penetrate the thick mountain, and the area of ​​the tunnel entrance alone is difficult to meet the needs of communication. [0003] At present, the way to solve the tunnel communication barrier mainly adopts the wired and wireless communication mode: the switch outside the tunnel is connected with the signal base station inside the tunnel through an optical cable to form a communication network. In this way, optical cables are easily affected by geology and topography, and the cost of laying optical cables is relatively high. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the present invention provides a radio t...
