Description
Technical Field
The invention belongs to the technical field of rail transit, and particularly relates to a train control technology of a tramcar.
Background
The train control system of the tramcar consists of a turnout control system (comprising a turnout controller and an intersection controller), a vehicle-mounted system and a dispatching command system. Before the train passes through the traffic signal, the front of the railway car confirms the front traffic signal locking and the switch locking direction through dynamic beacons or enhanced point code positions. Thus, the forward travel path is determined, and the tram positioning is kept from being lost by the coincidence of the actual path and the desired path.
Defects of the prior art: the front access open state cannot be obtained under the conditions of the positioned tramcar, missed reading of dynamic beacons and the like, and the position of the turnout is considered unknown. At this time, the driver RM mode drives the train to pass, which causes the position loss of the train, and the driver RM mode needs to drive through two positioning beacons again to complete positioning, thereby upgrading the train running mode. After the positioning is lost, the running speed and the like are limited, and the train operation and the like are affected considerably.

The specific technical scheme adopted by the invention and the beneficial effects brought by the technical scheme are disclosed in the following detailed description in combination with the drawings.
Drawings
The invention is further described with reference to the drawings and detailed description which follow:
fig. 1 is a schematic diagram of a specific application scenario according to an embodiment of the present invention.
Detailed Description
The technical solutions of the embodiments of the present invention will be explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present invention.
Along the tram operating line direction, divide into switch signal machine and non-switch signal machine with the signal machine of full line, wherein switch signal machine is used for the protection in switch region, and non-switch protection signal machine is used for crossing/does not contain the protection of switch route.
Typically, each switch section is provided with a switch signal at the entry location in the normal direction of operation. And a bidirectional operation section, wherein a reverse turnout annunciator is arranged at the outlet position. Other areas such as intersections that do not include switches may be configured and defined as non-switch traffic signals.
The turnout annunciator and the turnout annunciator for jurisdiction/protection need to be defined in the same interlocking area, so that code positions of all turnouts in the annunciator protection range can be obtained when the trolley and the rail bypass are ensured.
Moreover, all turnouts must have turnout protection annunciators in the passing direction, so that when the rail-mounted electric car runs, all turnouts in the way have code position state acquisition objects. Meanwhile, the arrangement of the signalers at non-key positions such as the access terminal signalers can be reduced.
Example 1
A method for positioning a tramcar crossing without losing based on communication comprises the following steps:
when the tramcar passes through the turnout area in RM mode, the tramcar communicates with the trackside equipment of the turnout area, and the turnout position is obtained through communication code bits;
the tramcar determines a walking path passing through the turnout area according to the turnout position, and passes through the turnout area according to the walking path;
after passing through the turnout area, the tram clears the corresponding turnout position.
Because the turnout protection annunciator is arranged in the corresponding turnout area, when the tramcar walks to the turnout protection annunciator protection area, the position information of all turnouts in the administration/protection range of the front turnout protection annunciator is acquired through the communication code position between the tramcar and the trackside equipment.
When the trolley RM mode passes through the turnout, the passing trend of the front turnout is obtained through the turnout code position, and the trolley walking approach is positioned/reversed, so that the turnout passing position is realized.
After passing through the turnout area, the tram clears the turnout position to avoid that the code state which is not updated is prolonged to be used for introducing abnormality in the last code state when passing through again.
The specific application scene flow is as follows:
as shown in fig. 1, DC0101 and DC0102 are switch protection annunciators, and the protection ranges thereof are crossover lines W0101, W0102, W0103 and W0104, and four switches. Wherein, DC0103, DC0104 are switch protection annunciator, and its protection scope is W0105 switch region. FC0102 is a non-turnout protection annunciator for protecting areas without turnouts.
And acquiring relevant turnout positions of relevant turnouts W0101, W0102, W0103, W0104 and the like before DC0101 along the uplink direction by taking positioning locking as an example, acquiring and updating expected running positions by the trolley, and after the turnout positions of the turnout regions W0101, W0102, W0103, W0104 and the like recorded by the system are kept positioned by the turnout positions of the turnout regions W0101 and W0102. And acquiring the W0105 turnout position before continuously running to DC0103, taking locking as an example, updating the expected running position of the trolley, and clearing the turnout region W0105 turnout position after the trolley passes through the W0105 in a positioning mode. When the trolley is operated to the DC0104 signaler along the irregular operation direction, only the switch W0105 is locked in the positioning state, the updated expected running direction is effective, and otherwise, the trolley is not at the safety side.
Therefore, the technical scheme is that when the tramcar passes through the turnout area in the RM mode, the tramcar is communicated with the trackside equipment in the turnout area, the turnout position is acquired through the communication code bit, the train positioning loss is avoided, the availability of a system in the RM mode can be improved, and the problem of the tramcar running red light to lose the positioning in the RM mode is solved.

An apparatus for passing through a fork area in a tram RM mode, comprising:
the turnout protection signal machine is arranged corresponding to the turnout area;
the track side equipment is arranged in the corresponding turnout area and is in communication connection with the turnout protection annunciator and the tramcar vehicle-mounted system;
the tramcar on-board system, the position information of all switches in the protection scope of switch protection signal machine is obtained through the communication sign indicating number position when tramcar on-board system and the other equipment of rail are communicated to confirm the walking route of place ahead through the switch region according to the switch position, and pass through the switch region according to this walking route control tramcar according to this walking route, and tramcar on-board system is clear corresponding switch position behind passing through the switch region.
