Technical Field
[0001] The utility model relates to the technical field of rail transit, in particular to a train passenger clearing confirmation system applied to the driverless mode. Background Art
[0002] At present, in the traditional automatic driving mode or controlled manual driving mode of the train control system based on wireless communication, after the train arrives at the turning-back station or the terminal station, it is necessary to clear the passengers on the train and prohibit passengers from boarding to ensure the operation safety of the train, and at the same time achieve the purpose of maintaining the station order and ensuring the safety of passengers. When clearing the passengers on the train, it needs to be intervened manually by the driver.
[0003] However, in addition to the automatic driving mode and the controlled manual driving mode, the train also has the full automatic driverless mode. When the train runs in this mode, since there is no driver on duty, when the train arrives at the turning-back station or the terminal station, the station staff generally reports by phone to clear the passengers on the train and prohibit passengers from boarding, and then the control center remotely issues commands to control the train and the platform screen doors. The way of reporting by phone takes a lot of time, resulting in low control efficiency after clearing the passengers. Moreover, the control center cannot monitor the on-site situation, and it can only adjust the control commands according to the content reported by phone. Once a situation where passengers suddenly break into the train occurs on site, it cannot react in time, there is a potential safety hazard of injuring passengers, and the safety is relatively low. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the disadvantages of low passenger clearing efficiency and inability to cope with emergencies and relatively low safety when the station staff reports the passenger clearing information by phone and then the control center issues control commands in the prior art. A train passenger clearing confirmation system applied to the driverless mode is provided. By setting a passenger clearing confirmation box at the platform to generate passenger clearing confirmation information, and then combining with the full electronic interlocking subsystem, the on-vehicle controller installed on the train is used to set the opening and closing commands of the platform screen doors, saving the time for reporting information, improving the control efficiency after clearing the passengers, and the passenger clearing confirmation information of the passenger clearing confirmation box can be adjusted according to the actual situation of the station at any time, being able to respond to emergencies in time and avoid safety accidents.
[0005] The purpose of the utility model is realized by the following technical solutions:

[0010] Furthermore, it further includes a distribution cabinet in which several communication links are provided. The full electronic interlocking subsystem is communicatively connected to the passenger evacuation confirmation box and the platform screen doors respectively through the corresponding communication links.
[0011] Furthermore, the full electronic interlocking subsystem includes a first passenger evacuation confirmation circuit and a second passenger evacuation confirmation circuit. Both the first passenger evacuation confirmation circuit and the second passenger evacuation confirmation circuit are communicatively connected to the passenger evacuation confirmation box through the corresponding communication links to collect the passenger evacuation confirmation information generated by the passenger evacuation confirmation box.
[0012] Furthermore, a passenger evacuation confirmation button is provided on the casing of the passenger evacuation confirmation box. The passenger evacuation confirmation box generates the passenger evacuation confirmation information according to the pressed state of the passenger evacuation confirmation button.
[0013] Furthermore, the passenger evacuation confirmation button includes a first normally open contact, a first fixed contact, a second normally open contact, a second fixed contact, a third normally open contact and a third fixed contact.

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0024] Embodiment:
[0025] A passenger clearance confirmation system for a train applied to the driverless mode, as Figure 1 shown, includes:
[0026] A passenger clearance confirmation box, which is arranged at the platform and is used for generating passenger clearance confirmation information;
[0027] A full electronic interlocking subsystem, which is communicatively connected with the passenger clearance confirmation box and is used for receiving and forwarding the passenger clearance confirmation information;
[0028] An on-vehicle controller, which is communicatively connected with the full electronic interlocking subsystem and is used for receiving the passenger clearance confirmation information and determining the opening and closing commands of the platform screen doors, forwarding the opening and closing commands of the platform screen doors to the full electronic interlocking subsystem to control the opening and closing of the platform screen doors.
[0029] The passenger clearance confirmation box is arranged at the platform of the reversing station or the terminal station. After the train arrives at the station, the station staff conducts the passenger clearance operation, and then generates the passenger clearance confirmation information by operating the passenger clearance confirmation box.
[0030] The all - electronic interlocking subsystem, as a train signal system for controlling train operation, can control and dispatch train operation through the communication system. Therefore, a communication connection can be set between the passenger - clearing confirmation box and the all - electronic interlocking subsystem, so as to utilize the signal system function of the all - electronic interlocking subsystem to forward the passenger - clearing confirmation information to the on - vehicle controller on the train. The on - vehicle controller performs logical processing to determine the door opening and closing commands, and then forwards the corresponding door opening and closing commands through the signal system function of the all - electronic interlocking subsystem to control the platform screen doors.
[0031] The on - vehicle controller, as a control system installed on the train, has functions such as operation control, fault diagnosis, and information display. After receiving the passenger - clearing confirmation information forwarded by the all - electronic interlocking subsystem, it can perform logical calculations on the passenger - clearing confirmation information to determine the platform door opening and closing commands.
[0032] When determining the platform door opening and closing commands, the on - vehicle controller will also formulate the door opening and closing commands for the vehicle doors, and directly send the door opening and closing commands for the vehicle doors to the controller in the garage through the internal communication bus or specific control contacts to achieve the opening and closing control of the vehicle doors.
[0033] Among them, the passenger - clearing confirmation information generated by the passenger - clearing confirmation box is divided into confirmed status information and unconfirmed status information.
[0034] When the passenger - clearing confirmation information shows confirmed status information, after logical processing by the on - vehicle controller, it issues a train door - closing command to the vehicle, and at the same time issues a platform door - closing command, which is forwarded to the platform screen doors through the all - electronic interlocking subsystem to lock the platform screen doors. After the platform screen doors are closed and locked, they will report the closed status of the platform screen doors to the on - vehicle controller, and the on - vehicle controller will then control the train to depart according to the route command issued by the dispatching workstation of the control center.
[0035] When the passenger - clearing confirmation information shows unconfirmed status information, after logical processing by the on - vehicle controller, it continuously issues a train door - opening command to the vehicle, the train doors remain open, and at the same time continuously issues a platform door - opening command, which is forwarded to the platform screen doors through the all - electronic interlocking subsystem to keep the platform screen doors open all the time.
[0036] It also includes a distribution cabinet. There are several communication links set in the distribution cabinet. The all - electronic interlocking subsystem is respectively communicatively connected to the passenger - clearing confirmation box and the platform screen doors through the corresponding communication links.
[0037] One of the main functions of the distribution cabinet is to allocate the uses of the lines, distribute different signal lines, power lines, etc. to their respective corresponding ports or devices to establish communication links. Therefore, in order to optimize and improve the signal transmission efficiency, the communication connections between the all - electronic interlocking subsystem and the passenger - clearing confirmation box and the platform screen doors are established through the distribution cabinet.
[0038] The full electronic interlocking subsystem includes a first passenger evacuation confirmation circuit and a second passenger evacuation confirmation circuit. Both the first passenger evacuation confirmation circuit and the second passenger evacuation confirmation circuit are communicatively connected to the passenger evacuation confirmation box through corresponding communication links to collect the passenger evacuation confirmation information generated by the passenger evacuation confirmation box.
[0039] Both the first passenger evacuation confirmation circuit and the second passenger evacuation circuit are arranged in the interlocking cabinet of the full electronic interlocking subsystem. The interlocking cabinet specifically includes an A-system acquisition unit EIB board and a B-system acquisition unit EIB board. The first passenger evacuation confirmation circuit is arranged in the A-system acquisition unit EIB board, and the second passenger evacuation confirmation circuit is arranged in the B-system acquisition unit EIB board. The passenger evacuation confirmation signal is collected through the first passenger evacuation confirmation circuit and the second passenger evacuation circuit.
[0040] As Figure 2 shown, a passenger evacuation confirmation button and a prompt light are arranged on the box body of the passenger evacuation confirmation box. The passenger evacuation confirmation box generates passenger evacuation confirmation information according to the pressed state of the passenger evacuation confirmation button.
[0041] The passenger evacuation confirmation information is generated by the pressed state of the button. When an emergency occurs on the platform, the passenger evacuation confirmation information can be adjusted in time by adjusting the pressed state of the passenger evacuation confirmation button, thereby avoiding the situation that passengers suddenly break into the train and get injured.
[0042] The passenger evacuation confirmation button includes a first fixed contact QKA1, a first normally open contact QKA2, a second normally open contact QKA3, a second fixed contact QKA4, a third fixed contact QKA5 and a third normally open contact QKA6. The first normally open contact QKA2 is connected to the positive input terminal QKA(A)+ of the first passenger evacuation confirmation circuit and the positive input terminal QKA(B)+ of the second passenger evacuation confirmation circuit respectively through the F-XX-3 port of the distribution cabinet by line X3. The first fixed contact QKA1 is connected to the third fixed contact QKA5. The second normally open contact QKA3 is connected to the third normally open contact QKA6. The second fixed contact QKA4 is connected to the negative input terminal QKA(A)- of the first passenger evacuation confirmation circuit and the negative input terminal QKA(A)- of the second passenger evacuation confirmation circuit respectively through the F-XX-4 port of the distribution cabinet by line X4. The third normally open contact QKA6 and the third fixed contact QKA5 are also connected to the first external power supply LF24 and the second external power supply LZ24 respectively through the F-XX-2 port and the F-XX-1 port of the distribution cabinet by line X2 and line X1.
[0043] The circuit connection among the first passenger evacuation confirmation circuit, the second passenger evacuation confirmation circuit and the passenger evacuation confirmation button is specifically as Figure 3As shown in the figure, the first external power supply LF24 and the second external power supply LZ24 are both 24V power supplies. To ensure the safety of the circuit, a fuse RD is provided at the second external power supply LZ24.
[0044] The first external power supply LF24 and the second external power supply LZ24 are arranged in the switch cabinet, and in this embodiment, the distribution cabinet specifically adopts a lightning protection distribution cabinet.
[0045] Figure 2 In the all-electronic interlocking subsystem, the first passenger evacuation confirmation circuit and the second passenger evacuation confirmation circuit are arranged in the interlocking cabinet. The EIB boards of the A-series acquisition unit and the EIB boards of the B-series acquisition unit are respectively located in different cages of the interlocking cabinet, and the confirmation status information of the passenger evacuation confirmation button is collected in real time.
[0046] Moreover, the contacts QKA1, QKA4, and QKA5 in the passenger evacuation confirmation button are equivalent, and the contacts QKA2, QKA3, and QKA6 are equivalent.
[0047] In addition, a status indicator light QKAD is also connected between the second normally open contact QKA3 and the third normally open contact QKA6. When the first normally open contact QKA2, the second normally open contact QKA3, and the third normally open contact QKA6 are all closed, the status indicator light QKAD lights up; when there is one normally open contact that is not closed, the status indicator light goes out.
[0048] The passenger evacuation confirmation button is a self-resetting button. When the self-resetting passenger evacuation confirmation button is pressed to make the passenger evacuation confirmation button in the "confirmed state", that is, the confirmed state information is generated. At this time, the contacts QKA1, QKA4, and QKA5 of the passenger evacuation confirmation button are connected to the corresponding contacts QKA2, QKA3, and QKA6. The first external power supply LF24 and the second external power supply LZ24 are introduced into the first passenger evacuation confirmation circuit and the second passenger evacuation confirmation circuit, so that a closed loop is formed, and the status indicator light QKAD lights up.
[0049] At this time, the EIB boards of the A-series acquisition unit and the EIB boards of the B-series acquisition unit corresponding to the first passenger evacuation confirmation circuit and the second passenger evacuation confirmation circuit collect the confirmed state information, and transmit the confirmed state information to the vehicle-mounted controller through the vehicle-ground communication link for logical processing and door closing command formulation.
[0050] When the self - resetting passenger - clearing confirmation button is released, the contacts QKA1, QKA4, and QKA5 of the passenger - clearing confirmation button are disconnected from the corresponding contacts QKA2, QKA3, and QKA6, the circuits of the first passenger - clearing confirmation circuit and the second passenger - clearing confirmation circuit are disconnected, the status indicator light QKAD goes out, and the A - series acquisition unit EIB board and the B - series acquisition unit EIB board corresponding to the first passenger - clearing confirmation circuit and the second passenger - clearing confirmation circuit collect non - confirmation status information, and transmit the confirmed status information to the vehicle controller through the vehicle - to - ground communication link for logical processing and door - opening command formulation.
[0051] The vehicle controller and the full - electronic interlocking subsystem are communicatively connected through the vehicle - to - ground communication link.
[0052] In addition to the information interaction between the vehicle controller and the full - electronic interlocking subsystem through the vehicle - to - ground communication link, when the vehicle controller receives the feedback signal of the platform door closed state, it will receive the route command issued by the control center dispatching workstation. At this time, the information interaction between the vehicle controller and the control center dispatching workstation also takes place through the vehicle - to - ground communication link.
[0053] The above - described embodiments are only a preferred solution of the present utility model, and do not impose any form of limitation on the present utility model. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
