Abstract
The invention discloses a kind of Cross talk loop wire and CBTC control systems, wherein Cross talk loop wire include two pairs of transmission lines disposed in parallel and it is disposed in parallel two docking take-up, it is described two pairs transmission line signal between two docking take-ups signal between there are 90 degree of phase differences.The spacing that line/reception line one step is two receiving coils of car antenna is sent for two pairs in CBTC control system.The present invention solves the problems, such as the signal blind zone in crosspoint, and fixed step size intersects so that inductive signal is relatively flat, due to the spacing that one step is two receiving coils of antenna box, thus effectively inhibits extraneous electromagnetic interference.
Description
Technical field
The present invention relates to technical field of rail traffic, and in particular to rail traffic CBTC control system.
Background technique
Refering to what is shown in Fig. 1, in rail traffic CBTC control system, currently used vehicle loop wire communication system use
It is parallel loop wire, this system is to be laid with parallel loop wire on ground, is incuded therewith using car antenna, carries out the transmission of signal and connect
By to realize the communication of mobile unit and trackside equipment.
Above-mentioned communication modes, in the case where no outside electromagnetic interference, parallel loop wire reception signal capabilities are stronger, send
Signal is also stronger.
But this means of communication has disadvantage, and it is more demanding to extraneous magnetic field environment, if the external world occurs same frequency electromagnetic interference,
Parallel loop wire can not inhibit its entrance, eventually lead to communication error code.
Summary of the invention
The technical problem to be solved by the invention is to provide one kind can effectively inhibit the intersection of outside electromagnetic interference logical
Interrogate loop wire.
In order to solve the above technical problems, the present invention adopts the following technical scheme: Cross talk loop wire, including it is disposed in parallel
Two pairs of transmission lines and it is disposed in parallel two docking take-up, it is described two pairs transmission line signal between and two docking take-ups signal it
Between there are 90 degree of phase differences.
The present invention also provides a kind of CBTC control system, including above-mentioned Cross talk loop wire and it is installed on vehicle
Car antenna, described two pairs send the spacing that line/reception line one step is two receiving coils of car antenna.
The technical solution adopted by the present invention, sends and receives two pairs of lines of each laying, between the signal of two pairs of transmission lines and two
It docks between the signal of take-up there are 90 degree of phase differences, this addresses the problem the signal blind zone problem in crosspoint, and fixed step size
Intersect so that inductive signal is relatively flat.Due to the spacing that one step is two receiving coils of antenna box, thus effectively suppression
Extraneous electromagnetic interference is made.
Detailed description of the invention
Fig. 1 is that the parallel loop wire that the prior art uses and car antenna cooperate schematic diagram；
Fig. 2 is that the Cross talk loop wire that the present invention uses and car antenna cooperate schematic diagram；
Fig. 3 is the Cross talk loop wire schematic diagram that the present invention uses.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Below
Description only actually at least one exemplary embodiment be it is illustrative, never as to the present invention and its application or make
Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment one, as shown in figure 3, Cross talk loop wire, including two pairs of transmission lines disposed in parallel and disposed in parallel
Two docking take-ups, two pairs transmission line signal between there are 90 degree of phase differences, meanwhile, two dock take-ups signal between it
Between there is also 90 degree of phase differences.Compared with original parallel loop wire, need to intersect inside Cross talk loop wire, and by original four pairs
It is four pairs of present lines that line, which increases, and this addresses the problem the signal blind zone problems in crosspoint, and external interference resistance is strong, and fixed
Step-length is intersected so that inductive signal is relatively flat, and intersection loop has no effect on the signal magnitude of positioning loop wire, will not be to positioning number
According to having an impact.
Embodiment two, as shown in Fig. 2, CBTC control system, including above-mentioned Cross talk loop wire and is installed on vehicle
Car antenna, two pairs send line/reception line one steps be two receiving coils of car antenna spacing, effectively inhibit
Extraneous electromagnetic interference.
In addition to above preferred embodiment, there are other embodiments of the invention, and those skilled in the art can be according to this
Invention makes various changes and modifications, and as long as it does not depart from the spirit of the invention, should belong in claims of the present invention and determines
The range of justice.
