Technical Field
The utility model relates to a radio field especially relates to a tunnel rescue antenna system.
Background
In this year, the safety accidents in mining production frequently occur in China, which arouses the wide social attention, and the safety production becomes the focus. Mine communication is also receiving more and more attention as a necessary means for scheduling global, front line command and safety monitoring. The mine communication system is divided into wired communication and wireless communication. The early and mature mine communication schemes at home and abroad basically adopt a wired communication mode, namely a wired telephone line or a leaky cable. However, in the mine communication system, there are problems with wired communication: firstly, in a mine, the mine is usually several kilometers or even dozens of kilometers, the laying cost of the cable is high, and the maintenance is difficult; secondly, most mines in China are mined manually, so that many mining procedures are needed, operation sites are scattered, personnel mobility is high, and wired communication cannot meet the flexible application.

The utility model discloses not enough in the aspect of the rescue of wired communication system in the tunnel provides a tunnel rescue antenna system.
The technical scheme adopted by the utility model is a roadway rescue antenna system, which comprises a personal antenna module, a relay receiving antenna module and a maintenance module, wherein the personal antenna module comprises a rod-shaped antenna and a radio transmitter, and the rod-shaped antenna is an omnidirectional antenna; the relay antenna module comprises a bidirectional radiation antenna and a protection box; the service module includes a protective case and a service component.
Preferably, the rod antenna includes: the antenna comprises a detachable antenna head, a middle antenna body of a rod-shaped structure and an antenna tail with threads; wherein the antenna tail is threadably engaged with the radio transmitter; the antenna head comprises an antenna cap, and the antenna cap is combined with the middle antenna body through threads; and the threads at the tail part of the antenna are matched with the threads of the antenna cap so as to realize the connection of the two middle antenna bodies.
Preferably, the protection case includes a fluorescent film formed by spraying a fluorescent material.
Preferably, the length of the rod antenna is 0.5 λ 0, where λ 0 is a free space wavelength corresponding to the operating frequency.
Preferably, the radio transmitter includes a wavelength selector that outputs a corresponding wavelength based on the number of combined antenna bodies.
The utility model discloses a tunnel rescue antenna system, through the personal electric wire that provides individual configuration and the relay line that is used for relaying for the maintenance module of maintenance system improves the personnel's in danger in the pit ability of calling for help.
Drawings
Fig. 1 is a schematic view of a roadway rescue antenna system according to the present invention;
fig. 2 is a schematic diagram of a rod antenna according to the present invention.
Detailed Description
The present invention is explained in conjunction with the following examples.
Based on the embodiment of the scheme, the roadway rescue antenna system as shown in fig. 1 comprises a personal antenna module, a relay receiving antenna module and a maintenance module, wherein the personal antenna module comprises a rod antenna and a radio transmitter, and the rod antenna is an omnidirectional antenna; the relay antenna module comprises a bidirectional radiation antenna and a protection box; the service module includes a protective case and a service component.
Accidents in the roadway can be classified into 2 types, workers can break away from the roadway and cannot break away from the roadway, and the system aims at the situation that the workers cannot break away from the roadway. The object of the personal antenna module is to provide a small, practical, modular transmitting antenna, the personal antenna module comprising a rod antenna, a radio transmitter, the rod antenna being connectable by means of threads at both ends, in order to enable the formation of a longer personal antenna when there are more than two survivors. The relay antenna module comprises a bidirectional radiation antenna and a protection box, the bidirectional radiation antenna is used for receiving signals sent by the personal antenna module and sending distress signals, meanwhile, the survival number is judged based on the signal receiving time of the personal antenna module (because the sending rules of the personal antenna module are the same), and the protection box is used for protecting the bidirectional radiation antenna.
As shown in fig. 2, the rod antenna comprises an antenna cap 1, an antenna body 2 and an antenna tail 3.
The rod antenna includes: the antenna comprises a detachable antenna head, a middle antenna body of a rod-shaped structure and an antenna tail with threads; wherein the antenna tail is threadably engaged with the radio transmitter; the antenna head comprises an antenna cap, and the antenna cap is combined with the middle antenna body through threads; and the threads at the tail part of the antenna are matched with the threads of the antenna cap so as to realize the connection of the two middle antenna bodies.
The protection box includes a fluorescent film formed by spraying a fluorescent material.
In case of a roadway accident, the possibility of power interruption is high, and in order to quickly find the protective box in a dark environment, it is important to realize illumination without using power because it is necessary to prevent the ignition of combustible gas by electric sparks.
The length of the rod antenna is 0.5 lambda 0, wherein lambda 0 is the free space wavelength corresponding to the working frequency.
The radio transmitter includes a wavelength selector that outputs a corresponding wavelength based on the number of combined antenna bodies.
By connecting the two rod antennas, the antenna length can be increased, and then the operating wavelength is changed by the wavelength selector to a multiple change, i.e. N λ 0, N being a multiple of 0.5.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention. The technical solution and/or the embodiments of the invention may be subject to various modifications and variations within the scope of the invention.
