Description

Unlocking control method for emergency escape door of train

Technical Field

The IEC 62290 classifies the operation functions of the urban rail transit management and control system into five grades according to the degree of automation, and conventional GOA2 and GOA3 grade subway trains are generally equipped with purely mechanically operated emergency escape doors, the opening and closing of which are controlled by drivers or crews. For an automatic train of a GOA4 (unattended automatic driving) grade, a cab is open to passengers, and no driver or crew can be provided, so that in an emergency, if the passengers can open the doors freely to escape, a safety accident can be caused. Therefore, on the basis of the original escape door device, a set of protection device is added, and passengers can operate the escape door to escape only after the escape door protection device is authorized to be unlocked.

In the prior art, an escape door protection device has relatively perfect hardware control, for example, patent No. CN109505481B provides an escape door hardware unlocking device for an unmanned train: in the technology, when the escape door needs to be opened, a passenger rotates the escape door request switch to an unlocking position, the unlocking device can generate an escape door unlocking request signal and sends the signal to the signal system, the signal system makes a decision after detecting the escape door unlocking request, if the escape door is allowed to be opened, unlocking permission (namely an ATC (advanced telecom computing) release electromagnet signal) is output, at the moment, the mechanical unlocking handle of the escape door can be operated to unlock, and the passenger can open the escape door by pulling the unlocking handle. Although the patent provides the escape door protection unlocking mode, the patent does not provide a perfect, safe and reliable unlocking control method, and cannot effectively avoid the problem that the electric device of the escape door cannot be unlocked due to human errors and system faults, and the safety and the reliability of the control mode of the protection device are required to be provided.

Example 1

The patent provides an unblock control method of signal system emergency exit protector, through central authorities remote control and local automatic control unblock intercombination, has further improved security and the reliability of emergency exit unblock, makes the passenger flee under the orderly organization of operation, prevents the secondary disaster that probably produces among the escape process, effectively avoids simultaneously because the problem of the unable unblock emergency exit electric installation that human error and system trouble brought.

The unlocking mode of the escape door protection device has two modes:

firstly, a central control unit ATS operator of a control center sends an unlocking command to carry out remote control unlocking;

and secondly, the passengers operate a local escape door unlocking request handle to request local automatic unlocking.

When a train driven by a driver has an emergency, the driver can unlock and open an escape door according to the operation rule according to the situation to organize passengers to escape; in case of emergency of unmanned trains in the grade of GOA4, the central dispatcher of the control center organizes passengers to escape according to operation rules by the control method for unlocking the escape door provided by the patent.

1. monitoring and acquiring an escape door unlocking request signal, and reporting the escape door unlocking request signal to a central control unit (ATS);

as shown in fig. 1, the emergency escape door is generally installed right in front of the driver's cab at both ends of the train as a front door. Fig. 1 shows a position where an emergency escape Door is installed on an unmanned train, and emergency escape Door guards of a Cab (front Door Cab) a and a Cab (front Door Cab) B are independently controlled. And a side Door (late Door) 1 and a side Door (late Door) 2 which are arranged at two sides of the train. An unlocking request handle of the escape door is an emergency escape door protection device which is conventionally arranged for a train, can be controlled by a central ATS, and can also be activated by passengers.

The train information management system TCMS monitors the opening state and the unlocking request state of the escape door on the train in real time, and once the escape door is opened, protective measures are taken according to areas, such as applying emergency braking to the train in a non-platform stop area. The train escape door unlocking request signal is triggered by manually operating an escape door request switch. Once the escape door request signal is triggered, the signal system will complete the designed action flow.

The escape door unlocking request signal is received and latched by a vehicle-mounted controller VOBC and reported to a central control unit ATS.

As an optional embodiment of the present application, optionally, monitoring and acquiring an emergency gate unlocking request signal, and reporting the emergency gate unlocking request signal to a central control unit ATS includes:

monitoring the state of an escape door on a train, monitoring and acquiring an escape door unlocking request signal when the escape door is opened, and sending the escape door unlocking request signal to a vehicle-mounted controller VOBC;

and the central control unit ATS receives and comprehensively monitors the CCTV camera of the escape door at the opening fault position of the ISCS system in a linkage manner to check the emergency condition of the train according to the unlocking request signal of the escape door.

With reference to the control system of fig. 4, the above specific implementation process includes:

(1) The vehicle-mounted subsystem latches an external escape door unlocking request signal as an input condition for controlling the unlocking of the escape door.

(2) The vehicle-mounted subsystem reports the latched unlocking request signal of the internal escape door to a train supervision subsystem (central control unit ATS), and can automatically send an obvious alarm to an operator on a central control unit ATS display screen of a control center to prompt the central control unit ATS operator to process.

(3) And (3) starting the CCTV cameras to be linked, when a person operates the escape door request handle to activate the escape door request handle, the vehicle-mounted communication system sends the information to the central control unit ATS, and the central control unit ATS links the comprehensive monitoring system to open the CCTV cameras of the escape doors at the fault positions.

2. The central control unit ATS judges whether to send an unlocking/unlocking prohibition command to an escape door unlocking request handle for unlocking or not according to the escape door unlocking request signal;

the central control unit ATS can be linked with a CCTV camera for comprehensively monitoring the ISCS system to check the emergency condition of the escape door at the train fault, an operator of the central control unit ATS can pay attention to the condition on the train and reasonably deal with the condition, and whether an unlocking/unlocking forbidding command is sent to the unlocking request handle of the escape door for unlocking is judged.

According to the embodiment, the escape door is provided with a front escape door and a rear escape door, and the front escape door, the rear escape door or the front escape door and the rear escape door can be organized to be opened for evacuation according to actual conditions. In order to prevent the influence of mistaken opening of the escape door on operation and ensure the safety in the escape process, the central dispatcher is given the highest priority to select whether to unlock the escape door and the mode of unlocking the escape door.

3. And if the central control unit ATS does not send an unlocking/unlocking forbidding command to the escape door unlocking request handle within the preset time, outputting the unlocking/unlocking forbidding command to the escape door unlocking request handle for unlocking through the vehicle-mounted subsystem according to the preset unlocking logic.

In addition, the patent also provides a mechanism for automatically unlocking the escape door locally, considering the delay of the communication between the central and local devices and preventing human errors. When the system detects that the unlocking request handle is activated, and the central operator does not give an instruction for unlocking the escape door or forbidding unlocking in time within the set time, the system automatically unlocks the escape door internally and gives passengers the opportunity of escaping.

The logic of the escape door unlocking is realized by a vehicle-mounted subsystem, and the output command is determined by the running state of the train, the operation command of the central control unit ATS remote emergency escape door and the state of an emergency escape door unlocking request handle on the train. The flow of the escape door logic control by the onboard controller VOBC will be described in detail below.

According to the logic judgment flow shown in the attached figure 2, the vehicle-mounted controller VOBC takes the train running state as a logic condition, generates a reasonable escape door unlocking enabling or prohibiting command output and acts on the emergency escape door protection device.

With reference to fig. 2, as an optional embodiment of the present application, optionally, outputting an unlocking/unlocking prohibition command to the emergency gate unlocking request handle for unlocking through the vehicle-mounted subsystem according to a preset unlocking logic includes:

acquiring and judging the running state of the train; the train running state is provided by a train information management system (TCMS);

and if the train running state is the moving state, outputting an escape door unlocking prohibition command, and prohibiting unlocking the escape door unlocking request handle through a vehicle-mounted controller VOBC. When the train is in a moving state, the vehicle-mounted controller VOBC prohibits the escape door from being unlocked, and the risk that passengers fall off the track due to the fact that the escape door is opened accidentally when the train moves is prevented.

acquiring and judging the train running state: the train running state is provided by a train information management system (TCMS);

if the train running state is a static state, judging whether the train is positioned: if yes, judging whether the train and the central communication CCU are established; otherwise, outputting an unlocking permission command of the escape door; when the train running state is a static state, judging whether the train is positioned, namely judging whether the position connection (communicating with a CCU (central communication unit) of a platform for position monitoring) is established at the train position;

if the train is connected with the CCU, judging the driving mode of the train; when the connection with the CCU is established, the unlocking control of the escape door is carried out according to the driving mode of the train, which will be described in detail below;

and if the train is not connected with the CCU, outputting an escape door unlocking permission command. No connection is established with the central communication CCU and no unlocking is allowed.

With reference to fig. 2, unlocking control modes of the escape door in three different states of a, B and C will be described in detail.

A. if the train running state is a static state, positioning is carried out, and the driving mode of the train is judged to be a non-signal protection manual driving mode: outputting an escape door unlocking permission command, and unlocking the unlocking request handle by default through a vehicle-mounted controller VOBC;

if the train is positioned when the train is static, when the running mode is the manual driving mode, a driver takes the lead to protect the escape doors of the two end cabs, so that the vehicle-mounted controller VOBC unlocks the electric unlocking devices of the escape doors of the two end cabs by default, and at the moment, the driver can open the escape doors only by operating the mechanical devices of the escape doors.

B. If the train running state is a static state, positioning is carried out, and the driving mode of the train is judged to be a manual/automatic mode of signal protection: if the escape door of the driver cab is judged to be the active end, an escape door unlocking permission command is output, and the unlocking request handle is unlocked by default through a vehicle-mounted controller VOBC; if the escape door of the driver cab is judged to be an inactive end and the driving mode is just switched to a manual/automatic driving mode of signal protection, an escape door unlocking prohibition command is output, and the unlocking of the unlocking request handle is prohibited by default through a vehicle-mounted controller VOBC; if the mode is not just switched to, the output state is kept, and an external request is responded;

specifically, when the train is in a static state and the train operation mode is a manual/automatic mode of signal protection, for the escape door of the driver cab at the activation end where the driver is located, if the manual driving mode is adopted, the vehicle-mounted controller VOBC unlocks the default escape door and is protected by the driver, and at the moment, the driver only needs to operate a mechanical device of the escape door to open the escape door.

And/or:

external requests and reactions are as follows: if the train is in a static state and is positioned, and the driving mode of the train is judged to be a manual/automatic driving mode for signal protection, and the cab where the escape door requested to be unlocked is located is an inactive end, then: remotely sending a command to the on-board controller VOBC through a central control unit ATS to determine whether to unlock the unlock request handle.

And for the escape door of the inactive side cab, the default is to prohibit unlocking, but whether the escape door is unlocked can be determined by remotely sending a command to the vehicle-mounted controller VOBC through the central control unit ATS.

C. if the train running state is a static state and positioning is performed, and the driving mode of the train is judged to be an unmanned driving mode, then:

judging whether the mode is just switched to: if yes, outputting an escape door unlocking prohibition command, and prohibiting unlocking the escape door unlocking request handle through a vehicle-mounted controller VOBC; otherwise, the output state is kept, and an external request is responded;

and/or:

If the train is still positioned, when the train running mode is the unmanned mode, the escape doors of the cab at two ends are set to be forbidden to be unlocked, but each escape door can remotely send a command to the vehicle-mounted controller VOBC through the central control unit ATS to determine whether to unlock.

The following will specifically describe the determination of whether or not the escape door switch is activated according to the operation of the escape door unlocking request handle by the passenger, and the control is performed on a case-by-case basis according to the activation state.

Referring to fig. 3, the handle is chronologically controlled by the state that the passenger activates according to the unlocking request of the escape door.

if the train running state is a static state and positioning exists, and the train driving mode is an automatic mode or an unmanned driving mode, if a user operates an unlocking request handle of the emergency escape door to request unlocking to a vehicle-mounted controller VOBC, judging whether the escape door request is changed into activation EED:

the external request switch is in a self-resetting type, namely the external request switch can rebound to an original non-activated position after operation activation, the vehicle-mounted controller VOBC needs to latch an external request signal, the external request signal is set to be a low level after a preset condition is met, and a timer is cleared; the preset conditions include: the unlocking request is reset and the escape door unlocking request is processed; or the ATS operator gives that the unlocking of the escape door is authorized; or disabled; or the escape door can be unlocked locally and automatically.

The external request switch is a self-reset switch, namely, the external request switch can rebound to the original non-activated position after being operated and activated. The vehicle-mounted controller VOBC needs to latch the external request signal and sets the control program thereof as follows: and setting the latch signal of the request to be low level after the preset condition is met, and clearing the timer.

The preset condition may be any one of the following cases:

the unlocking request is reset and the escape door unlocking request is processed; or

The ATS operator gives that the unlocking of the escape door is authorized; or

Forbidding; or

The escape door is unlocked locally and automatically.

The passenger may request unlocking from the VOBC of the vehicle by operating the emergency escape door unlocking request handle. When the request handle becomes active, the onboard controller VOBC starts a timer. And after the timing time is up, the vehicle-mounted controller VOBC immediately and automatically unlocks the double-end emergency escape door protection device. Before the timer is overtime, the central dispatcher can send a command to the vehicle-mounted controller VOBC to respectively control the emergency escape door protection devices at the two ends. The dispatcher can authorize the emergency escape door protection device at one end to unlock immediately, and forbid the emergency escape door protection device at the other end to unlock automatically; or both escape doors use the same command.

When a communication fault exists between the center and the local or the train is positioned and lost, the escape doors at the two ends are automatically unlocked in a reasonable time. After (emergency) parking, the central dispatcher can also directly send an escape door protection unlocking command to the vehicle-mounted controller VOBC on the central control unit ATS, and the vehicle-mounted controller VOBC immediately unlocks the escape door protection device after receiving the command. When the central dispatcher authorizes to unlock the escape door, passengers can be guided through vehicle broadcasting, and the mechanical lock of the escape door is operated to open the escape door for escape.

The software control is to realize signal transmission by the train integrated system, and a specific hardware system is described in embodiment 2.

Example 2

Based on the implementation principle of embodiment 1, the system architecture shown in fig. 4, on another aspect of the present application, provides a device for implementing the train emergency escape door unlocking control method, including:

According to fig. 4, the vehicle controller VOBC is initialized to a corresponding state and logically controls the unlocking of the escape door by the state machine. After acquiring the input state of the escape door unlocking request from an external system (vehicle), the vehicle-mounted controller VOBC performs internal processing (for example, for a self-reset unlocking request device, the unlocking request is converted into a latched input state) and uploads the latched input state to the central control unit ATS. And a central dispatcher of the central control unit ATS operates to issue an escape door unlocking enabling/disabling enabling command to the vehicle-mounted controller VOBC, and the vehicle-mounted controller VOBC executes the operation of unlocking or not according to unlocking logic. The control flow of fig. 4 is shown in detail for each unit or module.

The deployment configuration of the above architecture will be configured according to the state machine shown in fig. 5:

1. and a relevant 'vehicle-signal' interface for monitoring and controlling the unlocking of the escape door is deployed.

1) And an escape door unlocking command of the escape door protection device is configured to output the train line.

Escape doors are arranged at the head positions of the drivers' cabs at the two ends of the train, and are independently controlled by a vehicle-mounted controller VOBC. The escape door unlocking command is a safe output command and is output to the train through two train lines. When the escape door protection device needs to be unlocked, the output of the two train lines is low level 0; when the escape door protection device is forbidden to be unlocked, the output of the two train lines is high level 1.

2) Configuration escape door unblock request state input train line

The vehicle-mounted controller VOBC monitors an unlocking request signal of the escape door protection device, wherein the signal is a safety input signal and is input into the vehicle-mounted controller VOBC through two train lines. When the request knob is pulled to a request position, the input of the two train lines is low level 0; when the request knob is in the reset position, both trainline inputs are high 1.

The state input of the escape door unlocking request can be divided into a self-resetting type and a non-self-resetting type according to different hardware of the unlocking request device, if the unlocking request device is of the self-resetting type, when the request operation is finished, a signal can not be maintained by self, software needs to latch the input request, namely after a valid high-level pulse is detected, the signal is stored into an internal variable of a vehicle-mounted controller (VOBC) and is set to be a high level, and after conditions are met (namely the unlocking request is reset and the escape door unlocking request is processed, if an operator of a central control unit (ATS) gives that the escape door unlocking is authorized or prohibited, or the escape door is unlocked locally and automatically), the internal variable is set to be a low level. If non-self-resetting, the external input signal may be self-sustained in the requested position without latching.

3) TCMS interface for configuring relative state of escape door

The monitoring state related to the unlocking of the escape door is redundantly collected in a network and electric train line mode, and the state of the unlocking request of the escape door of the train line and the network is randomly collected and activated, so that the condition that an external escape door request exists is considered.

2. Configuring an interface between a central control unit ATS and a vehicle controller VOBC

According to the system architecture of fig. 4, the onboard controller VOBC collects the input state of the escape door unlock request from the external system (vehicle), performs internal processing (for example, converts the unlock request into the latched input state for the self-reset unlock request device), and uploads the latched input state to the central control unit ATS. And a central dispatcher of the central control unit ATS operates to issue an escape door unlocking enabling/disabling enabling command to the vehicle-mounted controller VOBC, and the vehicle-mounted controller VOBC executes the operation of unlocking or not according to unlocking logic.

The command from the central control unit ATS to the vehicle-mounted controller VOBC is a safety command, needs to be confirmed by an operator, and guarantees the safety and reliability of command issuing.

The commands from the central control unit ATS to the on-board controller VOBC include:

enabling/prohibiting an unlocking command by the central remote escape door;

enabling an unlocking/prohibiting unlocking confirmation command of the central remote escape door;

the commands from the onboard controllers VOBC to the central control unit ATS include: and (4) an escape door unlocking request (latching) state.

The control flow is as follows:

the software implementation process of the escape door unlocking described in the invention is mainly completed by a vehicle-mounted controller VOBC, and according to the interface signals, the logic for realizing the specific escape door unlocking function by the following state machine flow chart is designed.

1) Initial state of escape door unlocking

After the vehicle-mounted controller VOBC is powered on, if the position of the train is successfully recovered and the vehicle-mounted controller VOBC enters an unmanned mode, the vehicle-mounted controller VOBC can output an unlocking prohibition command of the emergency escape door of the cab at two ends; if the position is successfully recovered and the vehicle-mounted controller VOBC enters an automatic mode, the vehicle-mounted controller VOBC outputs an unlocking command of the emergency escape door of the cab at the activated end and outputs an unlocking prohibition command of the emergency escape door at the inactivated end; if the position is successfully recovered and the vehicle-mounted controller VOBC enters the manual mode, the vehicle-mounted controller VOBC outputs unlocking commands of the emergency escape doors of the two-end cab; and if the position recovery fails, the vehicle-mounted controller VOBC outputs an unlocking command of the emergency escape door of the cab at two ends.

2) Implementation of escape door unlocking logic

The vehicle-mounted controller VOBC is initialized to a corresponding state, and logic control is performed on unlocking of the escape door (shown in figure 5). The state machine has two layers, wherein the first layer is a main state machine and has two states of an Unblock Enable state and an Unblock Disable state, which represent whether an escape door unlocking command of the escape door protection device is unlocking Enable (low level) or unlocking Disable (high level). There is a sub-state machine (containing Idle, tounable, reliable, holdDisable four states) in the Unblock Disable state, which is used to implement the complex control logic of the escape door.

As shown in fig. 5, the state machine has two layers, the first layer is a main state machine, and has two states, namely an unblockable state and an unblockdisable state, which represent whether the emergency gate unlocking command of the emergency gate protection device is an unlocking Enable (low level) or an unlocking Disable (high level). In the Unblock Disable state, there is a sub-state machine (containing Idle, toEnable, reliable, holdDisable four states), and the input variables such as activation/deactivation of the escape door unlocking request, ATS escape door unlocking enable/Disable command of the central control unit, timeout of the request timer, etc. are used for realizing the complex control logic of the escape door.

Designing a main state machine:

unblock Enable state:

when the emergency escape door protection device jumps to the state, the escape door unlocking command of the emergency escape door protection device is refreshed to allow unlocking.

The conversion condition from the unblocked Enable state to the unblocked Disable state is as follows:

moving the train; or

The train is static, the operation mode is just changed into an automatic (ATPM/ATO) mode, and the escape door protection device needing evaluation currently is positioned in a cab at the inactive end; or

The train is stationary and the operation mode is just changed to FAM/OFF mode; or

The train is stationary and a valid EED Unblock Disable command is received and the mode is either unmanned (FAM) or automatic (ATPM/ATO) and the requested exit is located at the inactive cab end.

Unblock Disable state:

when the emergency escape door protection device jumps to the state, the escape door unlocking command of the emergency escape door protection device is refreshed to be unlocking forbidding.

The conversion condition from the unblocked Disable state to the unblocked Enable state is as follows:

when the train is static and the train is in a non-man driving (FAM/OFF) mode, the VOBC-ATC communication of the vehicle-mounted controller is cut OFF and exceeds a tolerance value; or

The train is in a manual (RMF/RMR) mode; or

The train is in automatic (ATO/ATPM) mode, and the currently evaluated escape door is positioned in the activated cab; or

The substate machine jumps To the To Enable state

2.2 sub-state machine design:

Sub state machine design:

idle state:

the Idle state is the initial state of the sub-state machines, and when the main state machine switches from the unblocked Enable state to the unblocked Disable state, the sub-state machines are set to this state when the escape door unlock request is not active. In the state, when the unlocking request of the escape door is activated, the sub-state machine jumps to a reliable state and starts a timer; and when receiving an unlock Enable Unblock Enable command sent by the central control unit ATS, the sub-state machine jumps To a To Enable state.

Retentive state:

in the state, when the escape door requests resetting, the sub-state machine jumps to an Idle state; when an unlock Enable Unblock Enable command sent by a central control unit ATS is received or a timer is overtime, the sub-state machine jumps To a To Enable state; and when receiving an unblocking Disable command sent by the central control unit ATS, the sub-state machine jumps to the Hold Disable state and clears the timer.

Hold Disable state:

when the main state machine is switched from the unblockable state to the unblockdisable state and the escape door unlocking request is activated, the sub-state machine is set to the state. In this state, when the escape door unlock request is reset, the sub-state machine jumps to the Idle state.

To Enable state:

this state is a temporary transition state that will unconditionally transition to the unblockable state of the main state machine.
