Abstract
The utility model relates to an antenna for inducing radio communication by using a guide line of a contact net as a wave guide line, which is used for receiving and transmitting signals in a motor-vehicle station. The utility model comprises an antenna part and an antenna tuned matching network part, wherein, the antenna forms a frame shape and is parallel to the contact net; the antenna can reliably be grounded through the connection to the vehicle body of the motor vehicle; the tuned matching network is a capacitive network. The utility model has the advantages of good electric property, short antenna length, light weight, small volume, convenient transportation and installation, no need of dismounting when the motor vehicle is overhauled, the elimination of induced voltage inducted from the guide line of the contact net to the antenna and better safety. Both the signal-receiving field strength and the transmitting field intensity are higher than that of a line antenna, the receiving-interference field intensity is lower than that of the line antenna.
Description
The utility model relate to a kind of under the induction wireless communication mode particularly with the radio station antenna assembly of contact line conducting wire as the induction wireless communication mode of waveguide wire.
At present, the employed antenna in radio station in the electric locomotive of China's electric railway employing induction wireless communication modes mostly is the parallel lines antenna, the antenna assembly (ZL86203376.U) that is used for induction wireless communication that for example scientific research institution, Zhengzhou Railway Administration Xi'an develops, the aluminum pipe long by 18m constitutes, its structure is simpler, solved mountain area electric railway communication issue, but because of it is a field coupled, interference free performance is relatively poor, longer dimension, transportation, it is very inconvenient to install, especially when locomotive overhaul, locomotive header must open, so antenna must be removed, must reinstall after locomotive is fixed again.Field experience shows, is dismantling and is reinstalling in the process, and antenna damages very general, gives and uses maintenance to make troubles.
The purpose of this utility model will overcome the existing deficiency of above-mentioned antenna exactly, designs a kind of novel magnetic field coupled modes, good electrical property, length is short, and in light weight, volume is little, fail safe is good, the antenna assembly that is used for induction wireless communication that need not remove during locomotive overhaul.
Goal of the invention of the present utility model is achieved through the following technical solutions: as the frame antenna device that waveguide wire carries out induction wireless communication, comprise the tuning matching network part of antenna part and antenna with contact line conducting wire.Antenna is a shaped as frame, parallel placement with contact line conducting wire, and the metallic conductor external packets of antenna is wrapped with insulating sleeve, and antenna is connected ground connection with locomotive car body; The tuning matching network of antenna is a capacitive network, and it is an independent box body, and an end is connected with antenna by cable, and the other end is connected with the radio station.Antenna installation is in the locomotive top, and antenna reaches high voltage protection by being connected with locomotive car body, and the tuning matching network of configuration antenna is to improve the emission field intensity.
Compared with the prior art the utility model has good electrical property, and length is short, and in light weight for 1/10th of wire antenna, volume is little, transports and install very convenient, need not remove during locomotive overhaul.This antenna is by connecting and reliable ground with car body in addition, thereby eliminates the induced voltage that is induced to antenna by contact line conducting wire, and fail safe is better.This antenna receiving signal field intensity emission field intensity all is higher than wire antenna, is lower than wire antenna and receive interference field strength.
Below in conjunction with drawings and Examples the utility model is done explanation in further detail.
Fig. 1 is this antenna assembly schematic diagram;
Fig. 2 is the tuning matching network circuit figure of antenna.
In the drawings, 1 is antenna, and 2 is insulating sleeve, and 3 is stube cable, and 4 is tuning matching network, and 5 is the radio station, and 6 is earth connection, and 7 is insulation board, and 8 is locomotive car body, and 9 is contact line.
In the present embodiment, the antenna assembly that is used for induction wireless communication is with the integral type frame antenna device of contact line conducting wire as waveguide wire, comprises the tuning matching network part of antenna part and antenna.Antenna 1 is the metallic conductor of multiturn lead coiled, and the conductor external packets is wrapped with ageing-resistant insulating sleeve 2, and antenna 1 is parallel with contact line 9.8 distances of antenna part and locomotive car body are 50～100mm, separate with heavy insulation plate 7, reach high voltage protection thereby antenna 1 is connected ground connection by earth connection 6 with locomotive car body; The tuning matching network 4 of configuration antenna is to improve the emission field intensity, tuning matching network 4 is an independent box body, its end is connected with the drop cable 3 of antenna 1 by 3～8m, the other end is connected with radio station 5, the formation of tuning matching network 4 is: series transformer B after 3 capacitor C 1, C2, the C3 parallel connection, on capacitor C 2, C3 branch road, be connected to K switch 2, K3 respectively, on the inferior utmost point n2 of transformer B, be connected to detection tube D and antenna current table branch road A.
