Drawings
Embodiments of the invention are described in further detail below with reference to the attached drawing figures, wherein:
FIG. 1 is a flow chart of a first embodiment;
FIG. 2 is another flow chart of the first embodiment;
FIG. 3 is a flowchart of the second embodiment;
FIG. 4 is a block diagram of a fourth embodiment.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Example one
The embodiment provides a broadcasting method for a train to arrive at a platform, as shown in fig. 1, comprising the following steps:
s1, when the train runs, acquiring the state information of each screen door, wherein the state information comprises: the shielding door opening method comprises closing state information and opening process information, wherein the closing state information is used for indicating that the shielding door is in a closing state, the opening process information is used for indicating that the shielding door is in an opening process, and the state information can be read from an interface point table of the shielding door and a master controller.
And S2, when the closing state information changes to the opening process information, starting the train to station broadcasting. Considering that a certain time is consumed in the judging process and the process of controlling the starting of the train arrival broadcast, the starting of the train arrival broadcast can be started when the state changes, and the train arrival broadcast starts to be broadcasted when the shielding door is completely opened.
Further, considering the case that the shield door may be in a failure, the open state of a single shield door does not necessarily represent that a train arrives at a station at some time, so when the closed state information changes to the open process information, the train arrives at the station and is started to broadcast, specifically: and starting a train to broadcast to a station when the closing state information of more than two shielding doors in the three continuous shielding doors on the same side is changed to the opening process information.
When a train goes up or down, more than two continuous three shielding doors in the unilateral train shielding doors change from a closed state to an open process, the fact that the train arrives at the station and the shielding doors are switched to be opened from the closed state can be proved, misjudgment is avoided, and accurate broadcasting of the arrival broadcasting of the train is achieved.
Further, the state information further includes: opening state information and closing process information; in order to further ensure that the train arrives at the station, when the closing state information of more than two shielding doors changes to the opening process information, the train arrival broadcasting is started in the three continuous shielding doors on the same side, and the method further comprises the following steps: and when the last state information of the closing state information is judged to be closing process information, the last state information of the closing process information is opening state information, and the duration time of the opening state information is more than 60 seconds, starting train arrival broadcasting, and based on the starting state information, accurately judging that the train is actually in the arrival state.
Further, before starting the train-to-station broadcast, the method also comprises the following steps: and when the train arrival broadcasting is judged not to be started, closing the platform line broadcasting and starting the train arrival broadcasting. That is, when the train arrives at the station, the broadcasting of the station line broadcast is being performed, and the broadcasting of the train arrival broadcast is started after the broadcasting of the station line broadcast is suspended.
Further, after the train arrival broadcasting is started, the method further comprises the following steps: and after judging that the broadcasting of the train arrival broadcasting is finished, starting the platform line broadcasting. That is, after the broadcasting of the train arrival broadcasting is completed, the broadcasting is switched back to the station line broadcasting.
The invention will be further explained with reference to specific embodiments as follows:
1. reading the state information of the shielding door from the interface point table, such as: the read state is a four-digit number, wherein the first digit represents an upper row and a lower row, 1 represents an upper row, 2 represents a lower row, the second represents a device type number, the third and the fourth represent a shielding door state, 01 represents closing state information, 10 represents opening state information, 00 represents non-opening and non-closing state information, the change from 01 to 00 is opening process information, the change from 10 to 00 is closing process information, and if: 1801, the screen door of No. 18 of the ascending train is represented, and the state of the screen door is closed.
2. Selecting three screen doors connected with the same side, in the continuous three screen doors on the same side, judging that the last state of the corresponding screen door is 10 at the moment when the state information of more than two screen doors changes from 01 to 00 and the duration is more than 60 seconds, closing the platform line broadcast, and starting the train arrival broadcast.
3. And after the broadcasting of the platform line broadcasting is finished, the broadcasting of the platform line broadcasting is recovered.
4. If the emergency broadcast is being played, the station line broadcast or train arrival broadcast is stopped.
Example two
The present embodiment provides another broadcasting method for train arrival at a station, which is different from the first embodiment in that: the embodiment is applied to island platforms with small space, and before starting the train arrival broadcasting, the method further comprises the following steps: and when the train arrival broadcasting is not started, closing the platform line broadcasting and starting the train arrival broadcasting.
The state parameter Pstate is set to be 1 when the train arrival broadcast is played and set to be 0 when the train arrival broadcast is not played, and whether the train arrival broadcast is played or not can be judged according to the state parameter.
Because the space of the island type platform is small, if the train arrival broadcasts of the ascending train and the descending train are played simultaneously, and the accurate time points of the two trains for playing are different, the sound confusion can be caused, and the listening of passengers can be influenced, therefore, when the train of one line arrives at the station, whether the train arrival broadcasts of the train are started or not needs to be judged, if the train arrival broadcasts of the train are started, the train arrival broadcasts of the train cannot be triggered, and the train arrival broadcasts of the other line are opposite, if the train arrival broadcasts of one line are judged to be not started, the train arrival broadcasts of the other line are proved to be not arrived, and the train arrival broadcasts need to be started.
The implementation process in this embodiment is the same as that in the first embodiment, and will not be described herein again.
