With the development of wireless communication technology, urban rail transit increasingly depends on a communication-based train control system. In a traditional signal control system, an enable signal and a disable signal of a signal machine are controlled by a computer interlock according to the block occupation condition in a line. But the train speed is faster and faster, the train length is too short or the communication quality is poor at present, so that the computer interlocking can not accurately control the signal machine into an enabling signal or a disabling signal. When the signal machine can not accurately display signals, the condition that a plurality of trains appear in the same line can appear, so that the problem of collision among the trains is easy to occur.
In view of this, the application provides a method, a device and a device for controlling a state of a signal light, so that an indication state of the signal light can be timely adjusted according to a train cross-pressure state of the signal light, and the problem of collision among a plurality of trains is avoided.
The inventive concept of the present application can be summarized as follows: the train crossing pressure state of the signal lamp is finally sent to the computer interlocking equipment, so that the computer interlocking equipment adjusts the indicating state of the signal lamp by utilizing the train crossing pressure state of the signal lamp, other trains needing to pass through the signal lamp can be timely reminded, and the problem of collision among a plurality of trains is avoided.
After the main inventive concept of the embodiment of the present application is introduced, an application scenario of a method for controlling a state of a traffic signal according to the embodiment of the present application is described below with reference to fig. 1. As shown in fig. 1, a Zone Controller (ZC) receives respective position information transmitted from a plurality of trains between a position a and a position B, and selects a train, which has a front wheel of the train not passing a signal lamp 1 and is closest to the signal lamp 1, from the plurality of trains as a target train based on the position information of each train at a current detection time.
Then, based on the current position information and the operating state of the target train, the predicted position information of the target train at the next detection time, for example, the predicted position information shown in fig. 1, is predicted to be located between the position B and the position C, that is, between the signal lamp 1 and the signal lamp 2. And determining whether the signal lamp 1 is pressed by the train between the current detection time and the next detection time according to the predicted position information of the target train at the next detection time and the position information of the signal lamp 1. And finally, sending the train pressure-crossing state of the signal lamp 1 to the computer interlocking device so that the computer interlocking device adjusts the indicating state of the signal lamp 1 according to the train pressure-crossing state of the signal lamp 1, for example, if the train pressure-crossing state of the signal lamp 1 is that the signal lamp 1 is pressed by the train, adjusting the indicating state of the signal lamp 1 to be no-pass through by the computer interlocking device, and if the train pressure-crossing state of the signal lamp 1 is that the signal lamp 1 is not pressed by the train and the indicating state of the signal lamp 1 is a pass state, not adjusting the indicating state of the signal lamp 1 by the computer interlocking device.
Of course, the method provided in the embodiment of the present application is not limited to the application scenario shown in fig. 1, and may also be used in other possible application scenarios, and the embodiment of the present application is not limited. The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described in the following method embodiments, and will not be described in detail herein.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.
Referring to fig. 2, a schematic flow chart of a method for controlling a state of a traffic signal according to an embodiment of the present application is shown. As shown in fig. 2, the control method of the traffic signal state may be applied to a zone controller, the method including the steps of:
And step 202, at the current detection time, according to the position information of each train, screening out the train with the front wheel of the train not passing through the signal lamp and the train closest to the signal lamp from the plurality of trains as a target train.
As shown in fig. 3, the position information of each of the train 1, the train 2, and the train 3 is received, and the train 3 closest to the signal lamp 1 among the train 1, the train 2, and the train 3 is set as the target train at the current detection time. As shown in fig. 4, the position information of each of the train 4 and the train 5 is received, and at the current detection time, the train 5 whose front wheel does not pass the signal lamp 1 and is closest to the signal lamp 1 is set as the target train. Here, the target train is installed with a wireless communication module, and the position information of the target train can be sent to the zone controller through the wireless communication module, and the target train is a train installed with a CBTC system.
After the target train is determined, step 203 is continuously executed to predict the predicted position information of the target train at the next detection time based on the current position information and the operation state of the target train.
Alternatively, as shown in fig. 5, the predicted position information may be determined by:
step 501, obtaining the acceleration of the target train based on the maximum traction acceleration of the target train and the preset acceleration corresponding to the gradient of the line where the target train is located.
Illustratively, the sum of the maximum traction acceleration of the target train and a preset acceleration corresponding to the gradient of the line where the target train is located is taken as the acceleration of the target train. Here, the maximum traction acceleration of the target train may be determined after a plurality of experiments. The preset acceleration is determined through the worst slope of the line where the target train is located, and then the acceleration of the target train under the worst condition can be obtained, so that the predicted position information determined according to the acceleration of the target train under the worst condition is more accurate.
For example, the travel distance L2 of the target train in the time length of one detection period is calculated by the following formula one, wherein a represents the current acceleration of the target train, v represents the current speed of the target train, and t represents the time length of one detection period, i.e., the time difference between the current detection time and the next detection time. After the running distance L2 of the target train is obtained through calculation, as shown in fig. 6, based on the position X of the current locomotive of the target train, the locomotive running of the target train to the position Y at the next detection time is predicted, and further the predicted position information of the target train at the next detection time can be predicted.
L2= a t/2+ vt formula one
After predicting the predicted position information of the target train at the next detection time, the process continues to step 204, and a train pressure-crossing state in which whether the signal lamp is pressed by the train between the current detection time and the next detection time is determined based on the predicted position information of the target train at the next detection time and the position information of the signal lamp.
Optionally, as shown in fig. 7, the train voltage-crossing state of the signal lamp is determined as the voltage-crossing state of the signal lamp by the train through the following steps:
step 701, determining a pressure-spanning distance between a rear wheel of a target train and a signal lamp according to the position information of the rear wheel of the target train in the predicted position information;
and 703, if the voltage-crossing distance is not less than the actual distance, determining that the train voltage-crossing state of the signal lamp is the voltage-crossing state of the signal lamp by the train.
As an example, as can be seen from fig. 8, if the length of the target train is represented by L3, the distance between the target train and the signal lamp 1 is represented by L1, the distance between the front wheel of the target train and the vehicle head is represented by L4, the travel distance of the target train in the time difference between the current detection time and the next detection time is represented by L2, and the pressure-crossing distance between the rear wheel of the target train and the signal lamp 1 in the predicted position information is represented by L5, L5= L2+ L4-L3-L1. As can be seen from fig. 9, the actual distance between the tail and the signal lamp 1 in the target train actual position information is represented by L6. And if the L5 is not less than the L6, determining that the train pressure-crossing state of the signal lamp 1 is that the signal lamp 1 is pressed by the train.
After the train pressure-crossing state of the signal lamp is determined, step 205 is continuously executed, and the train pressure-crossing state of the signal lamp is sent to the computer interlocking device, so that the computer interlocking device adjusts the indication state of the signal lamp according to the train pressure-crossing state of the signal lamp.
In one possible embodiment, after the train pressure-crossing state of the signal lamp is determined to be the train pressure-crossing state of the signal lamp, the information that the train pressure-crossing state of the signal lamp is sent to the computer interlocking device, so that the computer interlocking device adjusts the indication state of the signal lamp to the traffic prohibition.
As shown in fig. 10, after the information that the train voltage state of the signal lamp is transmitted to the computer interlock device, the following steps may be further performed to continuously adjust the indication state of the signal lamp:
1001, after determining that the target train runs to the predicted position information, adjusting the train pressure-crossing state of a signal lamp to a state that the signal lamp is not pressed by the train;
step 1002, sending the information that the train pressure-crossing state of the signal lamp is that the signal lamp is not pressed by the train to the computer interlocking device, so that the computer interlocking device adjusts the indicating state of the signal lamp to be allowed to pass.
Optionally, as shown in fig. 11, the method for controlling the state of the traffic signal may further include the following steps:
1102, determining the train pressure-crossing state of the signal lamp as the train pressure-crossing state of the signal lamp according to the current position information of the train;
As shown in fig. 12a, it is assumed that the front wheel of the train 6 passes the signal light 1, the tail end of the train 6 does not pass the signal light 1, and the train 6 is closest to the signal light 1 to other trains are screened from the plurality of trains. And determining that the train pressure-crossing state of the signal lamp 1 is the train pressure-crossing state of the signal lamp 1 according to the current position information of the train 6, and sending the information that the train pressure-crossing state of the signal lamp 1 is the train pressure-crossing state of the signal lamp 1 to the computer interlocking equipment, so that the computer interlocking equipment adjusts the indicating state of the signal lamp 1 to be no-pass so as to avoid collision between other trains and the train 6.
As shown in fig. 12b, if the predicted position information at the next detection time of the train 7 still does not pass through the signal lamp 1, the train pressure state of the signal lamp 1 is determined to be that the signal lamp 1 is not pressed by the train at the current detection time.
