Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
At present, the personnel safety protection measures of the waiting platform in the rail transit industry generally ensure the personal safety and the driving safety of passengers waiting for the platform by drawing a safety yellow line, maintaining personnel or a fully-closed integral shielding door of a subway underground station. However, although these methods have a certain protection effect on the safety of passengers on the platform to a certain extent, they cannot completely and effectively prevent the platform from accidental safety accidents, and the workload of platform workers is increased to a certain extent, which causes potential safety hazards to the personnel and the safe driving of rail transit, and increases the operation cost.
The invention provides a novel platform safety prevention and control system, aiming at solving the problems of insufficient safety protection measures and high operation cost of platform personnel in the rail transit industry. Specifically, the platform security prevention and control system of the embodiment of the present invention is described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a platform security and control system according to an embodiment of the present invention. It should be noted that the platform safety prevention and control system of the present invention is applicable to active safety protection for platform personnel in the rail transit industry, especially in an open type platform area for waiting vehicles without shielding or with half shielding. As shown in fig. 1, the platform security prevention and control system may include: a first detection device 110, a second detection device 120, a control device 130 and a station reminder device 140.
In particular, the first detection device 110 may be used to detect a first security thread area a. The second detection device 120 may be used to detect a second security thread area B. In the embodiment of the present invention, the distance between the first line of defense area a and the train track G is greater than the distance between the second line of defense area B and the train track G.
As an example, the first safety line area a may be used to indicate a first safety yellow line on a station platform, which is located in an area matching a detection area of the first detection apparatus 110. The second safety line area B may be used to indicate a second safety yellow line on the station platform, which is located in an area matching the detection area of the second detection apparatus 110. The second safety yellow line can be on the same side of the train track as the first safety yellow line, and the distance between the second safety yellow line and the train track is smaller than the distance between the first safety yellow line and the train track. For example, taking a subway station as an example, the second safety yellow line may be a safety warning line on which a platform screen door is located on a platform of the station. Therefore, the first detection device and the second detection device are respectively arranged at different distances from the train track to detect whether a person crosses into a safety warning area on the station platform, so that the accident of the platform caused by the fact that the person is too close to the track can be avoided.
In an embodiment of the present invention, the control device 130 may be electrically connected to the first detection device 110 and the second detection device 120, respectively. The platform alert device 140 may be disposed on the station platform C and electrically connected to the control device 130. The control device 130 may be configured to send the first prompt message through the platform reminder device 140 when receiving a first trigger signal sent when the first detection device 110 detects that the first security defense area a is occupied, and/or send the second prompt message through the platform reminder device 140 when receiving a second trigger signal sent when the second detection device 120 detects that the second security defense area B is occupied.
As an example, the control apparatus 130 may be provided in a control room F of a station. The station reminder device 140 can include, but is not limited to, a first voice playing unit and/or a first alarm flashing light, etc. For example, as shown in fig. 2, taking the platform reminding device 140 including the first voice playing unit 141 and the first warning flashing light 142 as an example, the first voice playing unit 141 and the first warning flashing light 142 are respectively disposed at two ends of the platform between the first security defense area a and the second security defense area B. For example, the first voice playing unit 141 is disposed at the platform edge of the train entrance; the first warning flashing light 142 may be provided at the edge of the train exit platform.
That is, when the first detection device 110 detects that a person crosses into the first security defense area a, the first detection device 110 sends a trigger signal (i.e., the first trigger signal) for the situation. The control device 130 sends a first prompt message through the platform reminding device 140 when receiving the first trigger signal, so as to remind the passenger that the safety range is exceeded. When the second detecting device 120 detects that a person crosses into the second security defense area B, the second detecting device 120 sends a trigger signal (i.e., the second trigger signal) for the situation. When receiving the second trigger signal, the control device 130 sends a second prompt message through the platform reminding device 140 to remind the passenger that the passenger is beyond the safety range and the passenger and the driving safety are damaged. The station reminding device 140 can prompt in a voice playing mode and/or an alarm flashing mode.
As an example, if the passenger triggers a different security line area, the station reminder device 140 will be prompted in a different manner. For example, taking the platform reminding device 140 including the first voice playing unit 141 and the first warning flashing light 142 as an example, when the first detection device 110 detects that a person crosses into the first security defense area a, the control device 130 may send the first voice message through the first voice playing unit 141, such as "you have exceeded the security range", and may further flash and prompt at the first frequency through the first warning flashing light 142; when the second detection device 120 detects that a person crosses into the second security defense area B, the control device 130 may send a second voice message through the first voice playing unit 141, such as "your behavior endangers oneself and driving safety", and may further flash and prompt at a second frequency through the first warning flashing light 142.
In an embodiment of the present invention, the first detection device and the second detection device may detect light such as infrared light or laser light to determine whether a person is in the security line area. That is to say, can have light emission unit and light receiving unit among the check out test set, like this, whether can receive the detection light that light emission unit sent through light receiving unit, perhaps whether the time length of receiving the detection light that light emission unit sent through light receiving unit satisfies the mode of normal time length, judges whether the safety line of defence area is someone.
It can be understood that the light emitting unit and the light receiving unit can be arranged at one end of the safety line-of-defense area at the same time, so that whether people exist in the safety line-of-defense area can be detected by the light reflection principle; or the light emitting unit and the light receiving unit are respectively arranged at two ends of the safety defense line area, and whether people exist in the safety defense line area is detected in a mode of detecting whether the light can be received or not (or whether the duration of receiving the detection light is greater than a certain threshold value or not). Two different examples will be given below for the description.
As an example, the first detection device may include: a first light emitting unit and a first light receiving unit. The first light emitting unit and the first light receiving unit are both arranged at one end of the first safety defense line area. The second detection device may include: a second light emitting unit and a second light receiving unit. The second light emitting unit and the second light receiving unit are both arranged at one end of the second safety defense line area.
For example, as shown in fig. 1 and 2, the first detection device 110 may include a first light emitting unit and a first light receiving unit, both of which are disposed at one end of the first security thread area a. The second detecting device 120 may include a second light emitting unit and a second light receiving unit, both of which are disposed at one end of the second security thread area B. Thus, when the duration that the first light receiving unit receives the reflected light of the detection light emitted by the first light emitting unit and reflected by the obstacle is shorter than the first preset duration, the first detection device 110 can detect that a person crosses into the first security defense line area a; when the duration that the second light receiving unit receives the reflected light of the detection light emitted by the second light emitting unit and reflected by the obstacle is shorter than a second preset duration, the second detection device 120 detects that a person crosses into the second security defense line area B.
As another example, the first detection device may include: a first light emitting unit and a first light receiving unit. The first light emitting unit and the first light receiving unit are respectively arranged at two ends of the first safety defense line area. The second detection device may include: a second light emitting unit and a second light receiving unit. The second light emitting unit and the second light receiving unit are respectively arranged at two ends of the second safety defense line area.
For example, as shown in fig. 3, the first detection device 110 may include a first light emitting unit 111 and a first light receiving unit 112, the first light emitting unit 111 may be disposed at one end of the first security thread area a, and the first light receiving unit 112 may be disposed at the other end of the first security thread area a. The second detection device 120 may include a second light emitting unit 121 and a second light receiving unit 122, the second light emitting unit 121 may be disposed at one end of the second security thread area B, and the second light receiving unit 122 may be disposed at the other end of the second security thread area B. Thus, when the first light receiving unit 112 receives the reflected light that is emitted by the first light emitting unit 111 and that the detection light wants to be reflected by the obstacle for a time period longer than a third preset time period, the first detection device 110 detects that a person crosses into the first security defense line area a; when the time length that the second light receiving unit 122 receives the reflected light that is emitted by the second light emitting unit 121 and that the detection light wants to be reflected by the obstacle is longer than the fourth preset time length, the second detection device 120 detects that someone crosses into the second security thread area B.
It should be noted that, the detection device may have multiple sets of light emitting units and light receiving units, where the multiple sets of light emitting units and light receiving units may be both disposed at one end of the security defense line region, or the multiple sets of light emitting units and light receiving units are disposed at two ends of the security defense line region in a paired manner, that is, one light emitting unit is disposed at one end of the security defense line region, and the light receiving unit paired with the light emitting unit is disposed at the other end of the security defense line region. It is to be understood that the light emitting unit and the light receiving unit in the above-mentioned detection device may be designed in other ways, and may be designed accordingly according to actual needs, and the present invention is not limited in particular herein.
In order to further ensure the safety of passengers and trains, optionally, in an embodiment of the present invention, as shown in fig. 3, the platform safety prevention and control system may further include: trackside reminder device 150. The wayside reminding device 150 may be disposed on a wayside track at a preset distance L from the train entrance platform and electrically connected to the control device 130. The control device 130 may be configured to send a third prompt message through the trackside reminding device 150 when receiving a second trigger signal sent by the second detection device 120 when detecting that there is a person in the second security defense line area. As an example, the wayside reminder device 150 can include, but is not limited to, a second warning flashing light or the like.
That is, a wayside reminding device may be provided on a wayside located at a predetermined distance from the train entrance platform, for example, as shown in fig. 3, the black head above the train D indicates the train traveling direction, so that it can be seen that the left side of the platform C is the train entrance and the right side is the train exit. In this way, when the second detection device 120 detects that someone crosses into the second safety defense line area B, the control device 130 may prompt through the trackside reminding device 150, for example, taking the trackside reminding device 150 as an example of an alarm flashing light, and may control the alarm flashing light to flash at a certain frequency, so as to prompt the current platform accident situation of the train driver who will enter the station, and please take correct measures to avoid the accident, thereby reducing the occurrence of the accident, and ensuring the driving safety of the passenger and the train.
To further avoid the occurrence of unexpected safety accidents, optionally, in an embodiment of the present invention, as shown in fig. 3, the platform safety prevention and control system may further include: the control room reminder device 160. Wherein, the control room reminding device 160 is arranged in the station control room and electrically connected with the control device 130. The control device 130 may be configured to send the fourth prompt message through the control room reminder device 160 when receiving a first trigger signal sent when the first detection device 110 detects that the first security defense area is occupied, and/or send the fifth prompt message through the control room reminder device 160 when receiving a second trigger signal sent when the second detection device 120 detects that the second security defense area is occupied. As an example, control room reminder device 160 can include, but is not limited to, a second voice play unit and/or a third alarm flashing light, etc.
That is, a control room reminder device may be provided within the station controller, which may be a combination of voice and alarm flashing lights to implement an audible and visual alarm, for example. In this way, when the first detection device 110 detects that a person crosses into the first security defense area, the control device 130 may prompt through the control room reminding device 160 to remind the staff to pay attention to the platform situation. When the second detection device 120 detects that someone crosses into the second security defense line area, the control device 130 may prompt through the control room reminding device 160 to remind the staff to quickly arrive at the waiting platform for processing. From this, when someone crosses into the safety defense line region on waiting the platform, remind equipment through the control room that is located the station control room, send different suggestion to the staff to remind the staff to adopt different measures, can further avoid the emergence of unexpected incident through artificial assistance.
In order to improve the availability and feasibility of the system and prevent the occurrence of false alarm or false alarm of the system, optionally, in an embodiment of the present invention, the control device 130 turns off the detection functions of the first detection device 110 and the second detection device 120 when receiving a signal that the train D enters and stops at the platform C. In the present invention, the control device 130 starts the detection functions of the first detection device 110 and the second detection device 120 upon receiving a signal that the train D has moved off the platform C.
For example, taking the second security wire area above the platform screen door on the waiting platform as an example, the platform screen door can be linked with the detection functions of the first detection device and the second detection device. That is, the operation of opening the platform screen door and the detection function of closing the first and second detection devices may be linked, and the operation of closing the platform screen door and the detection function of starting the first and second detection devices may be linked. Therefore, when the train drives in and stops at the platform and the platform shield is normally opened, the control equipment can receive the signal from the platform shield door, the detection functions of the first detection equipment and the second detection equipment can be closed at the moment, and passengers can normally get on and off the train without being influenced; when the platform screen door is closed, namely a train leaves the platform, the platform screen door can receive signals from the platform screen door, and at the moment, the detection functions of the first detection device and the second detection device can be started to remind passengers staying at the platform to move back to a safe area.
For another example, the door control system on the train can be linked with the detection functions of the first detection device and the second detection device. Thus, when the train D enters and stops at the platform C and the door E is opened, the control device receives a signal sent by a door control system on the train D that the door E is opened, and at this time, the detection functions of the first detection device and the second detection device can be closed, and the passengers can normally get on or off the train without being affected (as the arrow between the safety line areas in fig. 1 to 3 indicates the passenger getting on or off the train); when the vehicle door E is closed, the control device receives a vehicle door E closing signal sent by a vehicle door control system on the train D, and at the moment, the detection functions of the first detection device and the second detection device can be started to remind passengers staying at the platform to move back to a safe area.
In order that those skilled in the art will be able to more clearly understand the present invention, the following description will be given by way of example.
Fig. 4 is a schematic circuit diagram of the platform safety prevention and control system according to the present invention. As shown in fig. 4, an alarm flashing light can be arranged beside a rail at a preset distance from a train entrance, and an alarm flashing light can be arranged at the edge of a platform at a train exit, and both the alarm flashing lights are electrically connected with the control equipment. In the invention, a passive loudspeaker sound box can be arranged at the edge of the platform, the passive loudspeaker sound box is electrically connected with the control equipment, and the sound box realizes the voice prompt function in the system. The two ends of the first safety defense line area are provided with the first light emitting units and the first light receiving units to achieve the detection function of whether a person strides into the safety defense line area, for example, multiple groups of first light emitting units and first light receiving units can be arranged to achieve a grating area, and the multiple groups of first light emitting units and the first light receiving units are electrically connected with the control device.
As shown in fig. 4, the second light emitting unit and the second light receiving unit are disposed at two ends of the second security defense line region to achieve a detection function of whether a person crosses into the security defense line region, for example, a plurality of groups of the second light emitting units and the second light receiving units may be disposed to achieve a grating region, and the plurality of groups of the second light emitting units and the second light receiving units are electrically connected to the control device.
For example, as shown in fig. 5, a diagram illustrating the specific dynamic effect of the platform security and control system of the present invention when the first security line is triggered is shown. When someone triggers the first defense line (i.e. the first safe defense line area) located at the safe yellow line position, the control device sends out a pre-recorded voice prompt through a voice playing unit (such as a sound box) in the platform reminding device to remind passengers that the defense line is beyond the safe range. Meanwhile, a control room reminding device positioned in the control room sends out audible and visual alarm to remind workers of paying attention to the platform condition; the alarm flashing light in the platform reminding equipment positioned at the edge of the platform flashes to remind a driver to pay attention to the platform condition and then determines whether to close the vehicle door and drive the vehicle.
As another example, as shown in fig. 6, it is a schematic diagram illustrating the specific dynamic effect of the platform security and control system of the present invention when the second security line is triggered. When someone triggers the second defense line (namely the second safety defense line area) positioned at the platform screen door, the control equipment sends out a pre-recorded voice prompt through a voice playing unit (such as a sound box) in the platform reminding equipment, so that passengers are reminded that the safety range is exceeded and the passengers and the driving safety are harmed. Meanwhile, a control room reminding device positioned in the control room sends out audible and visual alarm to remind workers to rapidly arrive at the station for processing; the alarm flashing light in the platform reminding equipment positioned at the edge of the platform flashes to remind a driver to pay attention to the platform condition and then determines whether to close the vehicle door and drive the vehicle. When a train is about to enter a station, a trackside reminding device (such as an alarm flashing light shown in fig. 6) which is positioned at a trackside 20 meters away from the station twinkles to remind a train driver who is not entering the station, and if an accident happens at the station, a correct countermeasure is required to be taken.
Therefore, the platform safety prevention and control system can automatically and autonomously remind passengers of personal safety when waiting at the platform; not only reminding passengers to pay attention, but also reminding operation and maintenance personnel and train drivers to pay attention to the platform condition; the operation and maintenance personnel and the driver can quickly make a response according to the alarm prompt, and the accident safety accidents of the platform personnel are killed or the loss is reduced to the minimum; a large number of platform workers do not need to be arranged, and the platform workers do not need to maintain the order of the platform constantly.
In summary, in the platform security defense and control system according to the embodiment of the invention, the first detection device is disposed in the first security defense area, the second detection device is disposed in the second security defense area, the platform reminding device is disposed on the platform, and the platform reminding device sends the first prompt information when receiving the first trigger signal sent when the first detection device detects that the first security defense area is occupied, and/or sends the second prompt information when receiving the second trigger signal sent when the second detection device detects that the second security defense area is occupied. Therefore, passengers can be automatically reminded to pay attention to personal safety according to a specific trigger state, operation and maintenance workers and train drivers are reminded to pay attention to the platform condition, automatic active protection is achieved, the occurrence of platform accident safety accidents can be prevented in advance, and the operation cost can be effectively reduced.
In order to implement the above embodiments, the present invention further provides a platform security control method.
Fig. 7 is a flowchart of a station security control method according to an embodiment of the invention. It should be noted that the platform security prevention and control method according to the embodiment of the present invention can be applied to the platform security prevention and control system according to any one of the above embodiments of the present invention. The platform safety prevention and control system can comprise a first detection device, a second detection device, a control device and a platform reminding device arranged on a platform. It should be noted that the platform safety prevention and control method according to the embodiment of the present invention can be described from the control device side.
As shown in fig. 7, the station security prevention and control method may include:
s710, detecting whether a person exists in a first safety line area through first detection equipment;
as an example, the first safety line area may be used to indicate a first safety yellow line on a station platform, which is located in an area matching a detection area of the first detection device.
S720, detecting whether a person is in a second safety line-of-defense area through second detection equipment, wherein the distance between the first safety line-of-defense area and the train track is larger than the distance between the second safety line-of-defense area and the train track;
as an example, the second safety line area may be used to indicate a second safety yellow line on the station platform, which is located in an area matching the detection area of the second detection device. The second safety yellow line can be on the same side of the train track as the first safety yellow line, and the distance between the second safety yellow line and the train track is smaller than the distance between the first safety yellow line and the train track. For example, taking a subway station as an example, the second safety yellow line may be a safety warning line on which a platform screen door is located on a platform of the station. Therefore, the first detection device and the second detection device are respectively arranged at different distances from the train track to detect whether a person crosses into a safety warning area on the station platform, so that the accident of the platform caused by the fact that the person is too close to the track can be avoided.
S730, when a first trigger signal sent by first detection equipment when detecting that a person is in a first safety defense line area is received, sending first prompt information through platform prompt equipment, wherein the platform prompt equipment is arranged on a platform; and/or when a second trigger signal sent when the second detection device detects that a person is in the second safety line area is received, sending second prompt information through the platform reminding device.
As an example, the station reminder device may include, but is not limited to, a first voice playing unit and/or a first alarm flashing light, etc. For example, taking the platform reminding device including the first voice playing unit and the first warning flashing light as an example, the first voice playing unit and the first warning flashing light are respectively disposed at two ends of the platform between the first security defense line area and the second security defense line area. For example, the first voice playing unit is arranged at the edge of the platform at the train entrance; the first alarm flashing light can be arranged at the edge of the platform at the train exit.
That is, when the first detection device detects that a person crosses into the first security defense area, the first detection device sends a trigger signal for the situation (i.e., the first trigger signal). When the control device receives the first trigger signal, the control device sends out first prompt information through the platform prompt device so as to prompt passengers that the first prompt information exceeds a safety range. When the second detection device detects that a person crosses into the second security defense area, the second detection device sends a trigger signal (i.e., the second trigger signal) for the situation. When the control device receives the second trigger signal, the control device sends out second prompt information through the platform prompt device so as to prompt passengers to exceed a safety range and harm the passengers and driving safety. The platform reminding equipment can prompt in a voice playing mode and/or an alarm flashing mode.
As an example, if the passenger triggers different security line areas, the prompting modes of the platform reminder device will be different. For example, taking the platform reminding device including the first voice playing unit and the first alarm flashing light as an example, when the first detection device detects that a person crosses into the first security defense line area, the control device may send the first voice message through the first voice playing unit, for example, "you have exceeded the security range", and may further flash and prompt at the first frequency through the first alarm flashing light; when the second detection device detects that a person crosses into the second security defense line area, the control device can send second voice information through the first voice playing unit, for example, "your behavior has endangered oneself and driving safety", and can also flash and prompt at a second frequency through the first alarm flashing light.
Optionally, in an embodiment of the present invention, when receiving the second trigger signal sent by the second detection device, the platform safety prevention and control method may further send a third prompt message through a wayside reminding device, where the wayside reminding device is disposed on a wayside at a preset distance from a platform at a train entrance. As one example, the wayside reminder device can include, but is not limited to, a second warning flashing light or the like.
That is, a wayside reminder device may be provided on a wayside at a predetermined distance from the train entry platform, for example, an alarm flashing light may be provided at a wayside position 20 meters from the train entry platform. Like this, when second check out test set detects someone and steps into second safety defense line region, the other warning equipment of controlgear accessible track reminds the equipment and indicates, for example, use the other warning equipment of track as the warning flashing light example, steerable this warning flashing light carries out the flashing light with certain frequency, with the current platform of train navigating mate that the suggestion will be come into the station unexpected condition appears, please take correct counter-measure, in order to avoid the emergence of unexpected incident, thereby the emergence of unexpected incident has been reduced, passenger self and train driving safety have been ensured.
Optionally, in an embodiment of the present invention, when receiving the first trigger signal sent by the first detection device, the platform safety prevention and control method may further send a fourth prompt message through a control room reminding device, where the control room reminding device is disposed in a station control room; and/or sending a fifth prompt message by the control room prompting device when the second trigger signal sent by the second detection device is received.
That is, a control room reminder device may be provided within the station controller, which may be a combination of voice and alarm flashing lights to implement an audible and visual alarm, for example. Therefore, when the first detection device detects that a person crosses into the first safety defense line area, the control device can prompt through the control room reminding device to remind the staff of paying attention to the platform condition. When the second detection device detects that someone crosses into the second safety defense line area, the control device can prompt through the control room reminding device to remind workers to rapidly process on the waiting platform. From this, when someone crosses into the safety defense line region on waiting the platform, remind equipment through the control room that is located the station control room, send different suggestion to the staff to remind the staff to adopt different measures, can further avoid the emergence of unexpected incident through artificial assistance.
In order to improve the availability and feasibility of the system and prevent the occurrence of false alarm or false alarm of the system, optionally, in an embodiment of the present invention, the platform safety prevention and control method may further turn off the detection functions of the first detection device and the second detection device when a signal that a train enters and stops at the platform is received; and starting the detection functions of the first detection device and the second detection device when a signal that the train drives away from the platform is received.
For example, taking the second security wire area above the platform screen door on the waiting platform as an example, the platform screen door can be linked with the detection functions of the first detection device and the second detection device. That is, the operation of opening the platform screen door and the detection function of closing the first and second detection devices may be linked, and the operation of closing the platform screen door and the detection function of starting the first and second detection devices may be linked. Therefore, when the train drives in and stops at the platform and the platform shield is normally opened, the control equipment can receive the signal from the platform shield door, the detection functions of the first detection equipment and the second detection equipment can be closed at the moment, and passengers can normally get on and off the train without being influenced; when the platform screen door is closed, namely a train leaves the platform, the platform screen door can receive signals from the platform screen door, and at the moment, the detection functions of the first detection device and the second detection device can be started to remind passengers staying at the platform to move back to a safe area.
For another example, the door control system on the train can be linked with the detection functions of the first detection device and the second detection device. Thus, when a train drives into and stops at a platform and the train door is opened, the control device receives a signal sent by a train door control system on the train to open the train door, the detection functions of the first detection device and the second detection device can be closed, and passengers can normally get on or off the train without being influenced (for example, an arrow between safety line areas in fig. 1 to 3 represents a passenger getting on or off area); when the vehicle door is closed, the control device receives a vehicle door closing signal sent by a vehicle door control system on the train, and at the moment, the detection functions of the first detection device and the second detection device can be started to remind passengers staying at the platform to move back to a safe area.
According to the platform safety prevention and control method provided by the embodiment of the invention, whether a person exists in the first safety line area is detected through the first detection device, and whether a person exists in the second safety line area is detected through the second detection device, so that the platform reminding device sends the first prompt information when receiving the first trigger signal sent when the first detection device detects that the person exists in the first safety line area, and/or the platform reminding device sends the second prompt information when receiving the second trigger signal sent when the second detection device detects that the person exists in the second safety line area. Therefore, passengers can be automatically reminded to pay attention to personal safety according to a specific trigger state, operation and maintenance workers and train drivers are reminded to pay attention to the platform condition, automatic active protection is achieved, the occurrence of platform accident safety accidents can be prevented in advance, and the operation cost can be effectively reduced.
