All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a train low-speed running lighting control method, device and medium.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
The railway tunnel is a narrow passage for train running, and the lighting fixtures are usually distributed in the tunnel at intervals of 50 m. When the train is in normal operation, the emergency lighting lamp of the tunnel is kept to be closed, and when the train is in emergency stop in the tunnel due to fire or fault, the emergency lighting lamp is automatically triggered to be opened according to the stop of the train or the vehicle speed is lower than a certain threshold value, so that basic lighting conditions are provided for people evacuation. It is therefore necessary to monitor the speed of travel of the train; the detection device is usually an in-place detection device, such as an infrared detection device and an ultrasonic detection device, the position or distance of an object is detected by utilizing infrared or ultrasonic technology, when the moving object reaches a preset target position, the detection device can send out a signal or trigger corresponding action, and the running speed of the train is calculated by calculating the time that the train completely passes through one detection device.
However, when a single detection device of the railway tunnel lighting system fails, the tunnel lighting system is triggered to be automatically started, so that electric power energy is wasted, the service life of a lamp is shortened, and hidden dangers affecting normal running of a train exist.
In order to solve the above-mentioned problems, the present embodiment provides a method for controlling low-speed running illumination of a train, which is applied to an emergency illumination system, and fig. 1 is a schematic diagram of the emergency illumination system provided in the embodiment of the present application, as shown in fig. 1, including: a plurality of train detection units 11, a controller 12, and a lighting system 13; the train detection units 11 are respectively arranged in the train tunnel at equal intervals; the train detecting element comprises: a first type detection device 111, a second type detection device 112; the first type detection device 111 and the second type detection device 112 are respectively connected with the controller 12; the controller 12 is connected with the lighting system 13;
fig. 2 is a schematic diagram of a method for controlling low-speed running lighting of a train according to an embodiment of the present application, where, as shown in fig. 2, the method includes:
s11: the state signal of any one of the first type detection equipment 111 or the second type detection equipment 112 is detected to be a train arrival effective signal, and train arrival early warning information is sent;
s12: judging whether the state signal of any one of the first type detection equipment 111 or the second type detection equipment 112 except the detection equipment which is currently pre-warned is a train arrival effective signal or not within the preset checking time;
s13: if yes, confirming the arrival early warning information of the train, and judging whether the train runs at a low speed according to the distance and/or the triggering time of the two early-warning detection devices;
S14: if the operation is at a low speed, the illumination system 13 is controlled to be started.
It should be noted that the application environment of the present application is a monorail tunnel, that is, only one train is allowed to run in the tunnel at the same time.
As shown in fig. 1, the present application is applied to a train arrival early warning system, in which a controller 12 is configured to receive signals sent by a first type detection device 111 and a second type detection device 112 included in a train detection unit 11, so as to determine whether a train arrives and further determine whether the train runs at a low speed.
Specifically, the first type of detection device may be a piston wind pressure difference detection device, when a train enters a tunnel, a closed channel is formed in a space between a locomotive and the tunnel, the speed of the train causes pressure change of air flow in the tunnel, piston wind is generated on a running path, the detection device installed on the wall of the tunnel is affected by the piston wind, and two end air pressure differences δpab, δpab= |pa-pb| are formed in the horizontal direction of the train running, wherein Pa is inlet direction pressure, and Pb is outlet direction pressure. The first type of detection device 111 can then determine whether a vehicle is coming according to this principle.
In particular, the second type of detection device may be a train in-place detection device, which refers to a device for detecting whether an object has reached a target position or state. The accurate detection of the object position is usually realized by utilizing components such as a sensor, a processor, a signal processor and the like. Such as photoelectric sensors, infrared sensors, acoustic wave sensors. Theoretically, if a train arrives and the first type detection device 111 and the second type detection device 112 operate normally, the first type detection device 111 detects a signal earlier than the second type detection device 112.
The train arrival early warning system works normally, the controller 12 receives signals of all detection devices (in this application, for convenience of description, the first type detection device 111 and the second type detection device 112 are collectively referred to as detection devices), step S11 monitors that a status signal of any one of the first type detection device 111 and the second type detection device 112 is a train arrival effective signal, and sends out train arrival early warning information, and if any one of the detection devices sends out a train arrival effective signal, the sending out early warning information is equivalent to not completely believing the current detection device; the train arrival valid signal here refers to a signal considered valid with respect to the detecting device that sent the signal, and may be a signal directly collected by the detecting device or a signal that is processed and judged, which is not particularly limited in this embodiment.
When the status signal of the existing detection device is a train arrival valid signal, and after the train arrival early warning information is sent, step S12 is required to determine whether the status signal of any one of the first type detection device 111 or the second type detection device 112 other than the currently early-warned detection device is a train arrival valid signal within a preset verification time; i.e. a second detection device is required to check whether the signal of the first detection device is valid. The preset verification time mentioned in this embodiment may be set in a user-defined manner, and is generally set according to the running speed of the train on the track, and the interval distance set by the detection device. The second detection device may be co-located with the first detection device or may be different.
If it is detected that the status signal of any one of the first type of detection device 111 or the second type of detection device 112 other than the currently pre-warned detection device is a train arrival valid signal within the preset checking time, it is indicated that the train arrival pre-warning information sent by the first detection device is checked and confirmed by the second detection device, and if the train does arrive, a train arrival signal is sent. If the first detection equipment is false alarm, the signal of the second detection equipment is not received with high probability, and the accuracy of train arrival detection is improved.
When the arrival of the train is confirmed, whether the train runs at a low speed or not is judged, and if the train runs at a low speed is usually calculated, whether the train runs at a low speed or not is required to be judged according to the distance and/or the trigger time of two pre-warning detection devices. In a specific application, for example, whether the train runs at a low speed is determined according to the distance between two pre-warning detection devices, whether the distance between the two pre-warning detection devices is smaller than the shortest distance (the distance that the train runs at the lowest speed in a certain time) of theoretical running is determined, and if so, the low speed running of the train is described.
Judging whether the train runs at a low speed according to the triggering time of the two pre-warning detection devices. And (3) judging whether the used time is longer than the time required by theoretical running (the time required by running the train at the lowest speed in a certain interval) in a certain interval, and if so, indicating that the train runs at a low speed.
Judging whether the train runs at a low speed according to the distance between the two pre-warning detection devices and the trigger time, calculating a specific running speed according to the distance and the used time of the train, and judging whether the train runs at the low speed.
If it is determined that the vehicle is traveling at a low speed, the illumination system 13 needs to be controlled to turn on illumination, and a basic illumination condition is provided for evacuation of persons.
The train low-speed running lighting control method provided by the application is applied to an emergency lighting system 13 and comprises the following steps: a plurality of train detection units 11, a controller 12, and a lighting system 13; the train detection units 11 are respectively arranged in the train tunnel at equal intervals; the train detecting element comprises: a first type detection device 111, a second type detection device 112; the first type detection device 111 and the second type detection device 112 are respectively connected with the controller 12; the controller 12 is connected with the lighting system 13; the method comprises the following steps: the state signal of any one of the first type detection equipment 111 or the second type detection equipment 112 is detected to be a train arrival effective signal, and train arrival early warning information is sent; judging whether the state signal of any one of the first type detection equipment 111 or the second type detection equipment 112 except the detection equipment which is currently pre-warned is a train arrival effective signal or not within the preset checking time; if yes, confirming the arrival early warning information of the train, and judging whether the train runs at a low speed according to the distance and/or the triggering time of the two early-warning detection devices; if the operation is performed at a low speed, the illumination system 13 is controlled to illuminate. After the first detection equipment monitors the train, only the arrival early warning information of the train is sent out, the train is confirmed through the second detection equipment, whether the train runs at a low speed or not is judged after the arrival of the train is confirmed, if the first detection equipment is false alarm, signals of the second detection equipment are not received in a large probability, system false actions are not caused by faults of the single detection equipment, and the accuracy of the system is improved.
With the above embodiment, in order to further improve accuracy of sending out the train arrival valid signal by each detection device, this embodiment provides a preferred solution, where the status signal of the first type detection device 111 or the second type detection device 112 is the train arrival valid signal, including:
receiving a train arrival acquisition signal sent by the first type detection device 111 or the second type detection device 112;
judging whether the reliability of detection equipment sending out the train arrival acquisition signal is high or not;
if yes, setting a state signal of the detection equipment sending the train arrival acquisition signal as a train arrival effective signal;
if not, ignoring the current train arrival acquisition signal.
The train arrival acquisition signal mentioned in this embodiment refers to actual acquisition by the detection device, where the first type of detection device 111 detects that the wind pressure difference is greater than a preset value, and the second type of detection device 112 detects that the target position is blocked or the emission signal is reflected back; the controller 12 needs to determine the reliability of the detecting device sending the signal (the reliability is high or low, the high indicates that the detecting result of the detecting device is reliable, and the low indicates that the detecting result of the detecting device is not reliable) if the reliability of the detecting device is high, and sets the signal state of the detecting device as the train arrival effective signal, and if the reliability is low, ignores the train arrival acquisition signal sent by the detecting device. It should be noted that, the reliability is always required to be adjusted, and after a train passes, the controller 12 sets the reliability to be low if the signal detected by the detecting device is abnormal; if the operator overhauls the process, the reliability can be set to be high.
Through the scheme provided by the embodiment, only the acquisition signals sent by the detection equipment with high reliability can be used, so that the accuracy of train arrival detection is improved.
According to the above embodiment, the first type of detection device is a piston wind pressure difference detection device, and the second type of detection device is a train in-place detection device; because the first type detection device 111 and the second type detection device 112 have different detection principles, the first type detection device 111 is determined according to the wind pressure change in the tunnel, and is relatively more accurate, because it is difficult for non-train obstacles to generate a large wind pressure difference, while the second type detection device 112 may send out a false alarm due to the blocking of the obstacles, the false alarm is not a device fault, but cannot be adopted, and if the train arrival valid signal sent out by the false alarm is adopted, different processing is also required, therefore, in another embodiment, the monitoring that the status signal of any one of the first type detection device 111 or the second type detection device 112 is the train arrival valid signal, and sending out the train arrival early warning information includes:
if the state signal of the first type detection device 111 is detected to be a train arrival effective signal, immediately sending out the train arrival early warning information;
If the monitored status signal of the second type detection device 112 is a train arrival valid signal, judging whether the current status signal of the second type detection device 112 is still a train arrival valid signal after a preset confirmation time;
if yes, sending out the train arrival early warning information.
If the state signal of the first type detection device 111 is detected to be a train arrival effective signal, immediately sending train arrival early warning information without waiting for confirmation; if the signal is the second type detection device 112, judging whether the state signal of the second type detection device 112 is still a train arrival valid signal after the preset confirmation time; if yes, sending out train arrival early warning information. Judging that the state signal of the detection device is still a train arrival effective signal after the preset confirmation time, and sending out train arrival early warning information if the train is continuously detected. The embodiment further judges the train arrival effective signal sent by the detection equipment and eliminates false alarms.
It should be noted that, the preset confirmation time is set by user, and needs to be less than the shortest time that the train can pass through, that is, the train cannot pass through the detection device completely in this time.

The method and the device illustrate that the train runs at a low speed from the real-time detection device to the target detection device, and illumination is started in time.
