Exemplarily, fig. 2 shows a schematic flow chart of a transmission method of departure route information according to an embodiment of the present invention, and as shown in fig. 2, the method mainly includes the following steps:
the departure route track circuit receiver processes departure route state information according to the track information and sends the departure route state information to the station interlocking equipment;
the station interlocking equipment generates departure route information according to the departure route state information and sends the departure route information to a departure route track circuit transmitter;
the departure route track circuit transmitter adjusts the carrier frequency and the low frequency of the departure route information and transmits the adjusted departure route information to a steel rail;
and the track circuit information reader receives the adjusted departure route information from the steel rail, demodulates the adjusted departure route information and sends the demodulated information to the train control vehicle-mounted equipment.
The invention can realize the ground-vehicle information transmission of the receiving approach and the departure approach by arranging the track circuit transmitter and the track circuit receiver in the fixed section in the station and transmitting the special track circuit coding information. The in-station fixed section comprises a fixed section of a vehicle receiving access and a fixed section of a vehicle departure access. Further, the fixed section of the receiving approach is specifically a first section of the receiving approach or one or more specific sections on the receiving approach; the fixed section of the departure route is specifically the last section of the departure route or one or more specific sections of the departure route. When the train receives the route information in the fixed section in the station, the train can be controlled to run according to the actual route information of the route. It should be noted that, in the present invention, the transmission of the route information and the track circuit occupation inspection are integrated, so as to realize the closed-loop inspection of whether the ground reliably transmits the corresponding information.
Specifically, fig. 3 is a schematic diagram illustrating a principle of a method for transmitting receiving route information and departure route information according to an embodiment of the present invention, and as shown in fig. 3, a ZPW-2000 track circuit is taken as an example for the track circuit in the present invention. In this embodiment, the in-station fixed section is described by taking the first section of the receiving route and the last section of the departure route as examples. The track circuit transmitter in the first section of the receiving route transmits track information, which is illustrated as a frequency shift signal in this embodiment, to the steel rail, and the track circuit receiver receives the frequency shift signal from the steel rail. When no vehicle occupies the section, the track circuit transmitter transmits the frequency shift signal to the steel rail, and the track circuit receiver demodulates the frequency shift signal received from the receiving end of the track circuit receiver, so that the section is in an idle state, and section idle information is output; when a section is occupied by vehicles, the track circuit transmitter transmits the frequency shift signal to the steel rail, the train wheel set short-circuits the steel rail, and the track circuit receiver cannot demodulate the frequency shift signal received from the receiving end of the track circuit receiver, so that the section is in an occupied state, and section occupation information is output. In addition, the station interlocking equipment does not need to process the zone occupation state, and the zone occupation state information output by the track circuit can be directly used. When the track circuit transmitter sends the frequency shift signal to the steel rail and the track circuit receiver does not receive the frequency shift signal from the steel rail, the ground equipment gives alarm information to prompt that the access information is not transmitted to the steel rail or breaks down.
In this embodiment, before the train enters the first section of the receiving route (i.e., the IIAG section in fig. 3), the track circuit receiver of the first section of the receiving route demodulates the frequency-shifted signal transmitted by the track circuit transmitter of the first section of the receiving route, so as to process that the section is in an idle state, and outputs section idle information to the station interlocking device. And the station interlocking equipment judges that no train exists in the section according to the section idle information, so that the train receiving access information is not sent. When a train enters a first section of a receiving route, a train wheel set short-circuits a steel rail, and a track circuit receiver of the first section of the receiving route cannot demodulate a frequency shift signal sent by a track circuit transmitter of the first section of the receiving route, so that the section is in an occupied state, and section occupation state information is output to station interlocking equipment. And the station interlocking equipment generates the receiving route information according to the section occupation state information, wherein the receiving route information is transmitted in ZPW-2000 low-frequency information, and the specific position is on the seventh code bit. And the station interlocking equipment searches the corresponding route number from the route data table according to the receiving route information, and then sends the receiving route information to the track circuit transmitter in the current section according to the route number. The train receiving route starting module is used for handling train receiving routes for station interlocking equipment and correspondingly protecting train annunciators of the train receiving routes from being opened; the train receiving route ending module is used for preventing a train signal machine of the train receiving route from being closed, and stopping sending the train receiving route information after the train occupies the section and then is cleared. After the track circuit transmitter in the current section receives the pickup approach information, the low-frequency usage mode of the track circuit transmitter needs to be adjusted, and a combination mode of a carrier frequency reference, a small carrier frequency, a low frequency and the like can be adopted, but not limited to this, and the present embodiment exemplifies a combination of a carrier frequency and a low frequency. The station interlocking device finds the carrier frequency and the low frequency corresponding to the current receiving route information in a route data table according to the route number, as shown in the following table (1):
table (1) route data table
And then sending the corresponding carrier frequency and low frequency information to a track circuit transmitter of the current section, wherein the track circuit transmitter of the current section adjusts the carrier frequency and the low frequency of the receiving route information in an FSK (frequency shift keying) mode according to the corresponding carrier frequency and low frequency information, sends the information to a steel rail, and simultaneously completes the train occupation detection function.
It should be noted that, in table (1), only a part of the carrier frequency and low frequency combinations are selected as an example, and the remaining carrier frequency and low frequency combinations may also be used. The receiving approach refers to a path for entering and traveling, and the departure approach refers to a path for exiting and traveling; the route number refers to different paths traveled by the train when the train enters and leaves the station; the lines are the running directions of railway lines, wherein the running towards the Beijing is the uplink direction, the running towards the direction far away from the Beijing is the downlink direction, and the multi-line railway generally comprises an uplink line and a downlink line; the low frequency information is a combination of a carrier frequency and a low frequency, such as the low frequency information 1998.7-10.3 in serial number 1, wherein 1998.7Hz is the carrier frequency and 10.3Hz is the low frequency. The corresponding meaning of the low frequency information is only an exemplary illustration, and the meaning can be adjusted according to the actual requirement.
A TCR (track circuit information reader) in the train-mounted device receives, through an induction coil, the pickup route information transmitted by a track circuit transmitter through a steel rail, demodulates the pickup route information, and transmits the demodulated pickup route information to a train-mounted ATP (train control on-board device or other type of train control device) device. The vehicle-mounted ATP equipment receives the receiving route information provided by the TCR equipment, and combines line data, temporary speed limit, train information and the like to generate a train control curve on the receiving route so as to control the train to complete receiving operation.
In this embodiment, before a train enters the first section of the pickup approach, the interlock controls the track circuit in the IIAG section to transmit corresponding pickup approach information according to the already handled pickup approach, after the train is pressed into the IIAG, the vehicle-mounted TCR device receives the pickup approach information, and after the train is cleared of the IIAG (after the interlock receives that the IIAG section provided by the track circuit receiver in the IIAG section is changed from the occupied state to the idle state), the interlock controls the track circuit transmitter in the IIAG section to stop transmitting the pickup approach information.
In this embodiment, before a train enters the last section of the departure route, the interlock controls the track circuit in the IIBG section to transmit corresponding departure route information according to the handled departure route, after the train is pressed into the IIBG, the train-mounted TCR device receives the train receiving route information, and after the train is cleared of the IIBG (after the interlock receives that the IIBG section provided by the IIBG section track circuit receiver is changed from an occupied state to an idle state), the interlock controls the track circuit transmitter in the IIBG section to stop transmitting the departure route information. The transmission principle of departure route information is the same as that of receiving route information, the vehicle-mounted ATP equipment receives departure route information provided by the TCR equipment, and section data corresponding to the departure route is selected for controlling the train.
In this embodiment, the receiving route information and the departure route information are all total-station unique information, so that the train can accurately judge whether the receiving route information or the departure route information is received without distinguishing the running direction.
In order to implement the method for transmitting the receiving route information and the departure route information according to the present embodiment, a transmission system for the receiving route information and the departure route information is provided. As shown in fig. 4, the system includes a track circuit receiver, a station interlock device, a track circuit transmitter, and a track circuit information reader. Specifically, the track circuit transmitter transmits the track information to the steel rail; a track circuit receiver receives the track information from the steel rail; the track circuit receiver processes the section state information according to the track information and sends the section state information to the station interlocking equipment; the station interlocking equipment generates access information according to the section state information and sends the access information to the track circuit transmitter of the corresponding section; the track circuit transmitter adjusts the carrier frequency and the low frequency of the access information and transmits the adjusted access information to a steel rail; and the track circuit information reader receives the adjusted access information from the steel rail, demodulates the adjusted access information and sends the demodulated information to the train control vehicle-mounted equipment. The station interlocking equipment comprises a starting opportunity module and an ending opportunity module. Specifically, the starting time module handles and completes the route for the station interlocking equipment, and correspondingly protects the opening of a train signal machine of the route; the time ending module is used for preventing the train signal machine of the route from being closed, and stopping sending route information after the train occupies the section and then leaves the section.
The invention can complete the ground-vehicle information transmission of the receiving route information and the departure route information without adding extra equipment through the existing track circuit equipment, and can realize continuous and reliable transmission by transmitting the receiving route information and the departure route information through the track circuit. And the route information only needs to be transmitted in one direction to the train without train receipt, and the problem that the train does not receive the route information and the train makes the train misuse the receiving route data or the section basic data does not exist. The invention combines the route information with the existing signal authorization, solves the problem that the train only receives the signal authorization or the route information possibly by adopting two channels of the route information and the signal authorization in the prior art, and improves the driving safety and the driving efficiency.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
