Abstract
The utility model relates to a locomotive signal automatic carrier frequency switching device. In the existing locomotive signal system, the locomotive driver needs to manually control the selection of the uplink and the downlink carrier frequencies according to the zone where the locomotive runs, and the manual control mode brings a large workload to the driver and has a high risk of serious accidents caused by that the locomotive signal light is turned on by mistake due to switching errors. The automatic carrier frequency switching device for locomotive signals comprises a locomotive signal automatic carrier frequency switching main machine (1), wherein the locomotive signal automatic carrier frequency switching main machine (1) is connected with a locomotive power source (2), a locomotive signal main machine (3), a locomotive signal eight-display light mechanism (4), a locomotive train running monitoring record device or a TAX2 type locomotive safety information comprehensive monitoring device (5) respectively. The device is applied to the automatic carrier frequency switching of the locomotive signals.
Description
Technical field:
The utility model relates to the automatic carrier frequency shifter of a kind of cab signal.
Background technology:
In order to ensure traffic safety, prevent the intrusion of adjacent line interfering signal, the cab signal system must have the function by the cooresponding uplink and downlink CF signal decoding of ground rail circuit.In existing cab signal system, the selection of uplink and downlink carrier frequency needs the trainman to control manually according to the section that is moved.This manual control mode has not only caused very big work load to the driver, and occurs false transitions easily, causes lamp on the cab signal mistake, thereby causes the serious consequence of train operation accident.
Summary of the invention:
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of cab signal automatic carrier frequency shifter, carries out cab signal decoding accurately and prevents intrusion that adjacent line the disturbs influence to cab signal decoding.
Above-mentioned purpose is achieved through the following technical solutions:
The automatic carrier frequency shifter of cab signal, its composition comprises: the automatic carrier frequency of cab signal switches main frame, and the automatic carrier frequency of described cab signal switches main frame and connects electrical locomotive power, cab signal main frame, cab signal eight display lamp mechanisms, train operation monitoring and recording device or TAX2 type locomotive safety information comprehensive monitoring device respectively.
Beneficial effect:
1. the utility model is by increasing cab signal carrier frequency automatic switching control equipment on the basis of existing cab signal main frame, thereby realize the automatic switchover of cab signal carrier frequency, thereby alleviate trainman's manual operation work capacity, avoid because the train operation accident that manual control mode false transitions causes.
2. thereby the safe train operation information sent by real-time collection train operation monitoring and recording device of the utility model is judged the uplink and downlink state of the ground rail circuit uplink and downlink situation decision cab signal decoding in current locomotive operation place automatically, then upper and lower state is outputed to the cab signal main frame; The cab signal main frame carries out locking and hand-off process according to the uplink and downlink state to the decoding carrier frequency, thereby carries out cab signal decoding accurately and prevent the influence of the intrusion of adjacent line interference to cab signal decoding.
Description of drawings:
Fig. 1 is the structural representation of utility model.
Fig. 2 is a fundamental diagram of the present utility model.
Fig. 3 is that the automatic carrier frequency of cab signal switches main frame output control circuit figure.
Fig. 4 is the circuit diagram that the automatic carrier frequency of cab signal switches main frame USB part.
Fig. 5 is that the automatic carrier frequency of cab signal switches main frame peripheral hardware expanded circuit figure.
According to the electronic chart relevant regulations, the circuit of same pin has annexation.
The specific embodiment:
Embodiment 1:
The automatic carrier frequency shifter of cab signal, its composition comprises: the automatic carrier frequency of cab signal switches main frame 1, and the automatic carrier frequency of described cab signal switches main frame and connects electrical locomotive power 2, cab signal main frame 3, cab signal eight display lamp mechanisms 4, train operation monitoring and recording device or TAX2 type locomotive safety information comprehensive monitoring device 5 respectively.
Working process of the present utility model is:
The safe train operation information that needs to carry out carrier frequency switching place in the train operation route sector data automatic carrier frequency of cab signal of packing into is in advance switched in the mainframe memory;
Gather safe train operation information in train operation monitoring and recording device or the TAX2 type locomotive safety information comprehensive monitoring device output data (car station number, segment number, signal numbering, strand Taoist monastic name, train number etc.) in real time by electrical interface in the locomotive operation process;
The master cpu that the automatic carrier frequency of cab signal switches main frame is judged the uplink and downlink of locomotive automatically according to above information, and exports uplink and downlink information to the cab signal main frame;
The cab signal main frame switches the signal lamp that uplink and downlink information that main frame sends sends ground (red, green, yellow, yellow 2, yellow 2 sudden strain of a muscle, two Huang, two yellow sudden strain of a muscle, reddish yellow, reddish yellow dodge, white etc.) coding according to the automatic carrier frequency of cab signal and carries out safe and reliable signal decoding, and the lamp demonstration information (signal) that decoding obtains is outputed to eight display machines engine man's indicators shows.
Claims (1)
1. automatic carrier frequency shifter of cab signal, its composition comprises: cab signal carrier frequency shifter is characterized in that: the automatic carrier frequency of described cab signal switches main frame and connects electrical locomotive power, cab signal main frame, cab signal eight display lamp mechanisms, train operation monitoring and recording device or TAX2 type locomotive safety information comprehensive monitoring device respectively.
