Description

Control method and device for changing running direction of train

Technical Field

The invention relates to the technical field of train control interlocking, in particular to a control method and a control device for changing the running direction of a train.

Background

For single-line automatic block and double-line bidirectional automatic block, because the section needs to run both the downstream train and the upstream train, in order to avoid the situation that trains in two stations run oppositely, a circuit for changing the running direction needs to be designed between the two stations to realize the change of the running direction, namely, the station receiving station and the station sending station are determined.

At present, for the design of the traditional circuit for changing the running direction, the software for changing the running direction used by the relay four-wire system changing circuit and the train control center is widely adopted, wherein the relay four-wire system changing circuit mainly comprises a direction relay circuit, a supervision interval relay circuit, a local circuit, an auxiliary circuit and a light indicating circuit, and the function of changing the running direction by relaying is realized by 15 relays, and the software for changing the running direction of the train control center is mostly realized by referring to the design method of the original relay changing circuit, so that the operation of changing the running direction of the two circuits is practically the same.

The method for changing the running direction is divided into a normal handling mode and an auxiliary handling mode, wherein the normal handling mode is a handling method when a circuit for changing the running direction is in a normal state, and the method mainly comprises the following steps: the operator on duty at the original station handles a departure route, so that the square changing circuit can act, and the running direction can be automatically changed. The auxiliary handling is a handling mode which is used for enabling a directional circuit to recover to be normal when a fault occurs in the process of changing the running direction, and mainly comprises the following steps: when the track circuit in the block section has a fault, the operation direction can be changed only by using an auxiliary direction changing mode, namely, a duty worker at the original receiving station presses the total auxiliary button and the departure auxiliary button, simultaneously or later, the duty worker at the original receiving station presses the total auxiliary button and the receiving auxiliary button, and when the departure lamp lights a green lamp, the receiving lamp lights a yellow lamp, the direction changing is finished.

Specifically, as an exemplary example, the method of changing the operation direction is implemented by relying on the design of a traditional circuit for changing the operation direction, and the method is divided into two modes, namely normal transaction and auxiliary transaction. When normally handling, change the relay GFJ of running direction and suck after originally connecting station (being called this station) and handle the route of departure, make the direction relay FJ1 of adjacent station, direction relay FJ2 and the direction relay FJ2 of this station change utmost point, after the direction relay FJ1 of adjacent station changes utmost point, make adjacent station change the back that the relay GFJ of running direction fell down, and then make the direction relay FJ1 of this station change utmost point, change the process of changing the prescription to this point and end, adjacent station changes and connects the station into, this station changes into the station of departure.

And when the auxiliary reform is performed, the original station (called as the station) needs to press the main auxiliary button and the departure auxiliary button to suck the departure auxiliary relay FFJ, the adjacent station needs to press the main auxiliary button and the receiving auxiliary button to suck the receiving auxiliary relay JFJ, and further the auxiliary process change running direction relay FGFJ of the station is sucked, so that the running direction change relay GFJ is sucked, and the actions of the relay in the following reform process are the same as the normal process mode, and the reform operation is the same.

As mentioned above, for the conventional design of the circuit for changing the operation direction, as many as 15 relays are used, the circuit design is complicated, if the circuit fails, the circuit failure is difficult to recover in time for locating the failure, and due to the structural and characteristic limitations of the relay circuit, when the power supply is momentarily powered off, both stations are in the train receiving state (i.e., "double-connected"), in a special case, both stations are in the train sending state (i.e., "double-sent"), and if a similar abnormal direction state of double-connected and/or double-sent occurs, the train operation danger which is hard to imagine is caused.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The embodiment of the invention provides a control method for changing the running direction of a train, which is applied to preset running direction changing function software (hereinafter referred to as preset software), and can realize automatic change of direction between two adjacent stations on a line by using the preset software for change of direction operation regardless of normal handling or auxiliary handling, as shown in figure 1, the embodiment of the invention provides the following specific steps:

s101, for the mode of changing the running direction in normal handling or the mode of changing the running direction in auxiliary handling, when the situation that the first station receives a command of changing the running direction is monitored, detecting a parameter value of a receiving direction relay JCFJ and a parameter value of a departure direction relay FCFJ corresponding to the first station.

For the embodiment of the present invention, for convenience of explaining the embodiment of the present invention, any two adjacent stations on the line are identified as the first station and the second station, and there is no precedence order for the words "first" and "second", but only for convenience of explaining two different stations, so as to facilitate explaining how the preset software provided by the embodiment of the present invention changes the direction of any two adjacent stations.

The normal handling of the mode of changing the running direction is to solve the problem that the track circuit between any two adjacent stations is not in fault (namely, normal condition). If any station is originally a receiving station but needs to transact a departure route to an adjacent station, the station and the adjacent station need to change the running direction, namely, the operation of changing the direction is needed once. Or correspondingly, if any station is originally the original station, but the train receiving route to the adjacent station needs to be handled at present, the operation of changing the direction between the station and the adjacent station is also needed.

For the normal handling mode, if any station is originally the station of receiving the train, but the current need to handle the route of departure to the adjacent station, it will correspondingly trigger the operation of changing the side, otherwise, for the original station of the station, also when the need to handle the route of receiving the train, trigger the operation of changing the side.

And the auxiliary handling operation direction changing mode is to solve the problem that the track circuit between any two adjacent stations has a fault, namely, the side changing operation is executed when the section has a fault, a watchman confirms that the section has no car, and after the two adjacent stations press a fault side changing button of a corresponding direction port, the side changing operation is triggered.

The auxiliary party-changing mode needs to be particularly explained, and the auxiliary party-changing mode is characterized in that after the fault party-changing button of the corresponding direction port is pressed by the two adjacent stations stated above, the party-changing handling operation is correspondingly triggered.

As can be seen from comparison, although the trigger mechanisms for triggering the operation of the change of the transaction party in the normal transaction mode and the auxiliary transaction mode are different, the target station needs to change the running direction, and the preset software provided by the embodiment of the invention can be used for monitoring the instruction for changing the running direction, for example, the instruction includes the relevant instruction information for handling the departure route of the original station or handling the departure route of the original station. When such an instruction is monitored, the preset running direction changing function software can perform subsequent party changing operation between two adjacent stations, so that the universal operation of two handling modes by using the preset software is realized, and the requirements of different handling modes are met.

In the embodiment of the invention, a direction relay JCFJ and a departure direction relay FCFJ are configured in advance for a direction port of each station. If the receiving direction relay JCFJ is in the suck-up state but the departure direction relay FCFJ is in the drop-down state, it indicates that the station side crossing is the receiving direction, i.e. the station is the receiving station. If the receiving direction relay JCFJ is in the falling state but the departure direction relay FCFJ is in the suction state, it indicates that the station side crossing is the departure direction, that is, the station is the departure station.

The embodiment of the invention can monitor the states of the receiving direction relay JCFJ and the departure direction relay FCFJ of each station direction port by using the preset software, and exemplarily, the states can be represented by using parameter values, so that the state of the receiving direction relay JCFJ or the departure direction relay FCFJ can be known correspondingly by detecting the parameter value of the current receiving direction relay JCFJ and the corresponding parameter value of the current departure direction relay FCFJ.

S102, if the condition that the vehicle receiving direction relay JCFJ corresponding to the first vehicle station is in a suction-up state and the vehicle sending direction relay FCFJ is in a falling state is determined according to the parameter value of the vehicle receiving direction relay JCFJ and the parameter value of the vehicle sending direction relay FCFJ at present, the first vehicle station is determined to be the vehicle receiving station.

In the embodiment of the invention, the parameter value is used for representing the state of the receiving direction relay JCFJ or the departure direction relay FCFJ, so that correspondingly, after the parameter values of the two direction relays corresponding to the first station are detected by using the preset software, if the receiving direction relay JCFJ corresponding to the first station is determined to be in the suction state and the departure direction relay FCFJ is determined to be in the falling state, the first station can be further determined to be the receiving station.

S103, according to the instruction for changing the running direction, the running direction of the second station is changed into the station receiving station by adjusting the parameter value of the vehicle receiving direction relay JCFJ and the parameter value of the vehicle departure direction relay FCFJ corresponding to the second station.

And S104, changing the running direction of the first station into the departure station by adjusting the parameter value of the departure direction relay FCFJ and the parameter value of the receiving direction relay JCFJ corresponding to the first station.

In the embodiment of the present invention, the explanation is made in step 103-104, and if it is assumed that the first station is determined as the station to be picked up, the monitored instruction for changing the operation direction is to obtain a corresponding requirement that the first station is changed to the departure station and the second station is changed to the station to be picked up, and accordingly, the specific implementation method using the preset software is: firstly, adjusting a parameter value of a receiving direction relay JCFJ and a parameter value of a departure direction relay FCFJ corresponding to a second station to enable the receiving direction relay JCFJ to be in a suction state and the departure direction relay FCFJ to be in a falling state, and then changing the running direction of the second station into the receiving station; then, the parameter value of the receiving direction relay JCFJ and the parameter value of the departure direction relay FCFJ corresponding to the first station are adjusted, so that the receiving direction relay JCFJ is in a falling state, the departure direction relay FCFJ is in a sucking state, and the running direction of the first station is changed into the departure station.

Compared with the prior art, the method for controlling the change of the running direction of the train provided by the embodiment of the invention actually utilizes the preset function software for changing the running direction to realize the automatic change of the running direction between two stations on the line, does not need a large number of relays, and solves the problems that the circuit design is complex, the circuit fault is difficult to timely overhaul and the running danger of the train is brought because a large number of relays are needed by a change circuit adopted by the prior art.

In the embodiment of the invention, for the party-changing operation, no matter a normal handling mode or an auxiliary handling mode, the embodiment of the invention utilizes the preset running direction changing function software to monitor whether the station receives the party-changing operation instruction, and if the first station receives the instruction, the software is utilized to further determine that the first station is a receiving station or a sending station currently. Because the adjacent second station needs to be changed while the first station is changed, otherwise, the adjacent two stations have the condition of 'double connection' or 'double sending', when the first station is determined to be the receiving station, the embodiment of the invention can utilize the software to adjust and control the adjacent second station to be changed into the same direction port, and simultaneously adjust and control the direction port of the first station to be changed into the opposite direction, namely if the first station is the receiving station currently, the adjacent second station is adjusted and controlled to be changed into the receiving station, and simultaneously the first station is adjusted and controlled to be changed into the sending station.

The embodiment of the invention realizes simple operation steps by using software, can effectively and timely monitor the direction ports of two adjacent stations, can effectively avoid the condition of double connection or double transmission of the two adjacent stations in the process of changing the direction, and ensures the running safety of a train.

In order to describe the above embodiment in more detail, the embodiment of the present invention further provides another control method for changing a running direction of a train, where the method is also applied to preset function software for changing a running direction, as shown in fig. 2, and the embodiment of the present invention provides the following specific steps:

s201, configuring two relay variables for each station.

For convenience of explanation, the two relay variables include a first relay variable and a second relay variable, and the terms "first" and "second" are used herein to distinguish the variables without any other sequence.

The purpose of configuring the two relay variables is: because the direction port of each station is pre-configured with the train receiving direction relay JCFJ and the train departure direction relay FCFJ, and the parameter values corresponding to the relays in different directions are conveniently stored, in the preset function software for changing the running direction, the embodiment of the invention configures two relay variables for each station, and the specific explanation is as follows:

the first relay variable is used for storing parameter values respectively corresponding to the condition that the receiving direction relay JCFJ is in a suction state or a falling state; the second relay variable is used for storing parameter values corresponding to the departure direction relay FCFJ in a suction state or a falling state respectively.

Illustratively, the parameter values are characterized by 0 and 1. If the receiving direction relay JCFJ is in a suction state, setting a parameter value to be 1; if the receiving direction relay JCFJ is in a falling state, setting the parameter value to be 0. If the departure direction relay FCFJ is in a suction state, setting a parameter value to be 1; if the departure direction relay FCFJ is in the falling state, the set parameter value is 0.

And S202, configuring two relay excitation variables for each station.

For convenience of explanation, the two relay excitation variables comprise a first relay excitation variable and a second relay excitation variable, and the terms "first" and "second" are only used for conveniently referring to different relay excitation variables, and no other meanings of sequence exist.

The purpose of configuring two relay excitation variables for each station is as follows: in the embodiment of the present invention, although the suck-up state or the drop-down state of the directional relay can be represented by using the parameter values corresponding to the receiving directional relay JCFJ and the departure directional relay FCFJ, respectively, in the preset software, how to effectively trigger the parameter values of the directional relay to perform effective representation in time, the embodiment of the present invention adopts the two relay excitation variables to realize an effective trigger mechanism, and the specific explanation is as follows:

the embodiment of the invention provides a specific implementation method by using preset software, which comprises the following steps: the first relay excitation variable has an association relation with the first relay variable and is used for storing parameter values respectively corresponding to the condition that the relay excitation JCFJLC in the receiving direction is in a suction state or a falling state; and the second relay excitation variable and the second relay variable have an incidence relation and are used for storing parameter values respectively corresponding to the state that the departure direction relay excitation FCFJLC is in a suction state or a falling state.

Illustratively, the parameter values are characterized by 0 and 1. If the receiving direction relay excitation JCFJLC is in a suction state, setting a parameter value to be 1; and if the receiving direction relay excitation JCFJLC is in a falling state, setting the parameter value to be 0. If the departure direction relay excitation FCFJLC is in a suction state, setting a parameter value to be 1; if the departure direction relay excitation FCFJLC is in a falling state, the set parameter value is 0.

It should be noted that, in the embodiment of the present invention, the assignment to the first relay variable is triggered according to the corresponding parameter value assigned in the first relay excitation variable, specifically, if the assignment to the first relay excitation variable is parameter value 1, the assignment to the first relay variable is triggered; and if the value of the first relay excitation variable is 0, triggering to assign the parameter value into the first relay variable, wherein the detailed explanation is as follows:
