Specifically, the state information refers to the switch states of the PEP 1004 and the ESS 1003, and in a normal condition that the train can normally run, the switch state of the PEP 1004 is that the PEP contact is closed, and the switch state of the ESS 1003 is that the ESS contact is in the unset state. When the train encounters an emergency and needs to stop, the PEP 1004 can be pressed, the switch state of the PEP 1004 can be switched from the closed state of the PEP contact to the open state of the PEP contact, or the switch state of the ESS 1003 can be switched from the unseated state of the ESS contact to the parked state of the ESS contact when the ESS contact is pressed, so that the emergency stop control system is prompted to need to perform emergency stop control and audible and visual alarm control.

In practical applications, the all-electronic interlock device 1001, OC execution unit 1002, PEP1004, and ESS 1003 are connected through an emergency stop acquisition drive circuit. The all-electronic interlocking device 1001 and the OC execution unit 1002 of the emergency stop control system provided by the invention are only provided with one, and the all-electronic interlocking device 1001 and the OC execution unit 1002 can be arranged in the OC cabinet 230 of the OC execution unit 1002, wherein the OC cabinet 230 can be arranged at a station car control room for maintenance. Therefore, the original relays are replaced by the full-electronic interlocking equipment and the OC execution unit, the control circuit of the system is simplified, the full-electronic interlocking equipment of the system can collect the states of the outdoor PEP and the indoor ESS through the OC cabinet, different emergency stop scenes are distinguished according to the states, emergency stop clamping control under different scenes is carried out, and the safety of the system is improved.

Specifically, referring to fig. 2, fig. 2 is one of schematic diagrams of an emergency stop acquisition driving circuit of the emergency stop control system provided by the present invention. As shown in fig. 2, PEP 1004 at station platform 210 is provided with a first set of PEP contacts, a second set of PEP contacts and a third set of PEP contacts, and the OC cabinet 230 is provided with scattered input boards and scattered output boards, and ESS 1003 at station control room 240 is provided with a first set of ESS contacts and a second set of ESS contacts; acquisition lines of the first set of PEP contacts and the second set of PEP contacts are sequentially connected to the scattered input board cards through wiring of station platform lines 210 and a branching cabinet 220 of the signal station; the collection lines of the first set of ESS contacts and the second set of ESS contacts are connected to the scattered input board of the OC cabinet 230; the scattered input board is used for collecting state information of the PEP 1004 and the ESS 1003, and feeding back the state information to the all-electronic interlocking device 1001.

Specifically, the scattered input boards and the scattered output boards are respectively input boards and output boards of the all-electronic interlocking boards matched with the all-electronic interlocking equipment 1001. Thereby ensuring that the all-electronic interlock 1001 can gather PEP 1004 and ESS 1003 related press and closure information via the sporadic input board. The collection power sources of the PEP 1004 and the ESS 1003 may use DC24 adjustable power sources, so that the voltage may be adjusted according to the distance between the devices.

In practical applications, the number of PEPs 1004 and ESS 1003 is not limited, and the PEPs 1004 may use non-self-resetting buttons, that is, after the PEPs 1004 are pressed, the PEPs 1004 will remain in the position until released by a key, so as to ensure accuracy of the PEP state, and further ensure that the emergency parking control system can perform safe emergency parking control according to the PEP state. As shown in fig. 2, PEP1004 is provided with 3 sets of contacts, and the scattered input cards in OC cabinet 230 collect a first set of PEP contacts and a second set of PEP contacts, and the first stop-and-go indicator light of PEP1004 at station platform 210 uses a third set of PEP contacts. When the PEP1004 is pressed, the first stop indicator corresponding to the PEP1004 can effectively warn, so that the station personnel can clearly know that the PEP1004 is pressed successfully. Thereby ensuring safe close-up control to follow.

In addition, in order to ensure that the PEP 1004 located outdoors and the ESS 1003 located indoors can be mutually clamped, the whole emergency stop procedure is safer. The ESS 1003 is provided with 2 sets of contacts, and a first set of ESS contacts, a scattered input board card, and a first set of PEP contacts form a set of emergency stop acquisition driving circuits located at one side of the station platform, and a second set of ESS contacts, a scattered input board card, and a second set of PEP contacts form a set of emergency stop acquisition driving circuits located at the other side of the station platform. Through each group of emergency stop acquisition driving circuits, the full-electronic interlocking equipment can acquire the relevant pressing and closing information of the PEP and the ESS through scattered input boards, so that the outdoor PEP 1004 and the indoor ESS 1003 participate in flow card control and logic operation together according to the relevant pressing and closing information of the PEP 1004 and the ESS 1003, and card control is performed. The emergency stop system has the advantages that misoperation of station operators under emergency conditions is prevented because of excessive buttons of the vehicle control room, the emergency stop system has better safety and stability, and the system safety is effectively improved.

In practical application, the urban rail transit signal system is divided into different interlocking areas according to the station scale, and the signal station of each interlocking area comprises a signal centralized station and at least one signal non-centralized station; a platform emergency stop button PEP 1004 arranged at the station platform 210 and an emergency stop switch button ESS 1003 arranged at the station control room 240 are arranged in the signal concentration station and the signal non-concentration station; the signal concentration station is also internally provided with an all-electronic interlocking device 1001 and an object controller OC execution unit 1002, and the all-electronic interlocking device 1001 is connected with the ZC 200 in a wired way; the all-electronic interlocking device 1001 is further configured to generate an emergency stop signal matched with the emergency stop scene, and transmit the emergency stop signal to the ATP 300 through the ZC 200, so as to inform the ATP 300 of performing emergency stop control.

The state information of the PEP 1004 and the ESS 1003 is collected by the all-electronic interlocking device 1001 through the scattered input boards, the data is processed and logically operated by the interlocking host of the all-electronic interlocking device 1001, the specific scene when the PEP 1004 and the ESS 1003 are pressed is analyzed, corresponding control signals are output through the scattered output boards, the second emergency stop indicator lamp and the buzzer of the control room of the signal concentration station or the non-signal concentration station are controlled to carry out sound alarm and light alarm, and meanwhile, the all-electronic interlocking device 1001 sends an emergency stop signal to the ATP 300 through the ZC 200, so that the ATP 300 carries out corresponding emergency stop control, and personal injury of a train is avoided.

An emergency stop control method of the present invention is described below with reference to fig. 3-6.

Fig. 3 is a schematic flow chart of an emergency stop control method applied to an emergency stop control system according to the present invention, as shown in fig. 3, the method includes:

Step 10, the all-electronic interlocking device 1001 executes the sound-light alarm control matched with the emergency stop scene and sends an emergency stop signal to the ATP 300 to inform the ATP 300 to perform emergency stop control on each train when the emergency stop scene is identified;

in practical applications, when any one of the emergency stop buttons PEP 1004 and ESS 1003 is pressed and activated, the all-electronic interlock device 1001 acquires the state that the button is pressed and activated through the OC object execution unit 1002, and the all-electronic interlock device 1001 sends an emergency stop signal as a part of the movement authorization Movement Authority, MA to the ATP 300 through information interaction.

For trains that have not yet been inbound outside the platform area, ATP 300 controls the stopping of the trains that have not yet been inbound before the platform; emergency braking is carried out on the train of all or part of the body of the train in the platform area; for trains stopped at the platform area, the ATP 300 cuts off the traction train to prohibit the train from starting; for a train that is leaving, ATP 300 will make an emergency brake.

Specifically, the emergency stop scenario refers to an emergency stop alert scenario triggered by the relevant presses and closures of PEP 1004 and ESS 1003. The invention is mainly divided into a first emergency stop alarm scene triggered by the ESS 1003 and a second emergency stop alarm scene triggered by the ESS 1003. As shown in fig. 2, each group of emergency stop acquisition driving circuits is connected with at least one PEP 1004 and ESS 1003, and for different types of emergency stop buttons pressed, the all-electronic interlocking device 1001 of the present invention adopts different audible and visual alarm control logic to process, so as to perform emergency stop clamping control under different scenes, and improve the safety of the system.

Referring to fig. 4 and 5, fig. 4 is a first audible and visual alarm control logic of a first emergency stop alarm scenario triggered by pressing an ESS 1003 located in a vehicle control room, and fig. 5 is a second audible and visual alarm control logic of a second emergency stop alarm scenario triggered by pressing a PEP 1004 located at a station platform. Specifically, the all-electronic interlocking device 1001 executes the audible and visual alarm control for matching the emergency stop scene when the emergency stop scene is identified, and specifically includes:

When the PEP contact is switched to be disconnected in the emergency stop scene and the ESS contact is maintained in the unset state, the all-electronic interlocking device 1001 controls the first emergency stop indicator light and the buzzer to perform audible and visual alarm; or when the emergency stop scene is that the ESS contact is switched to the stop position and the PEP contact is kept closed, the all-electronic interlocking device 1001 controls the first emergency stop indicator lamp to perform a lamplight alarm.

In practical application, under the normal condition that the train can normally run, the switch state of the PEP 1004 is that the PEP contact is closed, and the switch state of the ESS is that the ESS contact is in the unset state. When the PEP 1004 at the station platform is pressed down to perform emergency stop alarm, the corresponding second emergency stop indicator lamp effectively performs flashing alarm, so that the platform personnel clearly know that the PEP 1004 is pressed down successfully. In addition, the frame is sprung on a relevant station control room and a workbench, and the voice alarm prompt is given: "Emergency stop", and the station platform is red, the ATP 300 authorized forward signal is released immediately, and ATP 300 starts to control the emergency stop of each train. Meanwhile, a first stop indicator lamp of the station control room gives a flashing stop indication, and a buzzer gives an audible alarm. When the ESS 1003 in the vehicle control room is pressed to give a stop alarm, that is, the ESS 1003 is set to the "stop" position, the PEP 1004 is not required to be operated. The ATP 300 may be disabled from outputting authorized traffic instructions when the ESS 1003 is set to the "stop" position. In addition, the frame is sprung on a relevant station control room and a workbench, and the voice alarm prompt is given: the first emergency stop indicator light of the station control room gives a stable stop indicator light to prompt operators in the car control room that ATP output of the authorized driving instructions is successfully forbidden.

And step 20, when the execution of the audible and visual alarm control is completed, the all-electronic interlocking device 1001 sends a recovery signal to the ATP 300 to inform the ATP 300 to recover the running state of each train.

In this step, the all-electronic interlocking device 1001 sends a recovery signal to the ATP 300 only when it monitors that the audible and visual alarm control is performed, thereby ensuring the safety of personnel and devices. Specifically, referring to fig. 4 and 5, when the audible and visual alarm control logic is executed from the first step to the fifth step or the audible and visual alarm control logic is executed from the first step to the third step, that is, when the PEP contact is maintained at the closed state and the ESS contact is switched to the unset state, the all-electronic interlock device 1001 determines that the audible and visual alarm control is executed.

According to the emergency stop control method provided by the invention, under the condition that the emergency stop scene is identified, the full-electronic interlocking equipment 1001 executes sound-light alarm control matched with the emergency stop scene and sends an emergency stop signal to the ATP 300 so as to inform the ATP 300 to carry out emergency stop control on each train; when the audible and visual alarm control is completed, the all-electronic interlock device 1001 transmits a restoration signal to the ATP 300 to notify the ATP 300 to restore the operation state of each train. Therefore, the full-electronic interlocking device 1001 adopts different audible and visual alarm control logic to process, so as to perform the close stop card control under different scenes, and also sends a recovery signal to the ATP 300 when the execution of the audible and visual alarm control is monitored, thereby improving the safety of the system.

In another embodiment, referring to fig. 6, fig. 6 is a second flowchart of the emergency stop control method provided by the present invention, as shown in fig. 6: the method for switching to off the PEP contact in the emergency stop scenario, where the ESS contact is maintained in the case of being out of position, after the full electronic interlock device 1001 controls the first emergency stop indicator light and the buzzer to perform an audible and visual alarm, further includes:

step 101, when the PEP contact is maintained to be opened and the ESS contact is switched to be deactivated, the all-electronic interlock device 1001 controls the buzzer to stop sounding alarm; or alternatively

Referring to fig. 4, when the ESS 1003 of the station control room is set at the "stop" position, the audible alarm of the buzzer will disappear, and the first stop-immediately indicator lamp will give a stable "stop" light alarm to prompt the operator ATP output authorized driving command in the car control room to be successfully disabled.

Step 102, when the PEP contact is switched to be closed and the ESS contact is maintained in the unset state, the all-electronic interlock device 1001 controls the first emergency stop indicator light and the buzzer to maintain an audible and visual alarm.

When the ESS 1003 of the station control room is not rotated to the stop position, the PEP1004 is released, the buzzer audible alarm is continuously given, the ATP authorized advancing signal is still disabled, and the first stop indicator lamp is displayed in a flashing stop light alarm mode so as to prompt operators in the vehicle control room to switch the ESS contacts to the stop position.

Furthermore, in another embodiment, after the full electronic interlock device 1001 controls the buzzer to stop sounding alarm in the case that the PEP contact is maintained in open and the ESS contact is switched to off, the method further includes:

And when the PEP contact is switched to be closed and the ESS contact is maintained at the stop position, the full-electronic interlocking device 1001 controls the first emergency stop indicator lamp and the buzzer to perform audible and visual alarm until the PEP contact is maintained to be closed, and when the ESS contact is switched to be out of position, controls the first emergency stop indicator lamp and the buzzer to stop audible and visual alarm.

In other words, the emergency stop control method provided by the invention can recover the ATP authorized forward signal and eliminate the audible alarm and the light alarm only when the ESS1003 of the station control room is set at the "stop" position and then set back at the "go" position. Thereby, the outdoor ESS1003 and the indoor PEP 1004 are mutually clamped and controlled, so that the whole emergency stop process is safer.

In addition, if the ESS 1003 of the station control room is set to the "stop" position and then turned back to the "go" position before the PEP 1004 is released, the alarm sound of the buzzer is given again, and the first stop indicator light is displayed with a flashing "stop" light alarm, and the alarm sound can be cut off only after the PEP 1004 is pressed and the ESS 1003 of the station control room is set to the "stop" position. After the reason for the operation is investigated and the safety condition is checked, the operator can release the PEP 1004, and when the PEP 1004 is released, an audible alarm and a flashing stop indicator light are also provided, so that the platform personnel clearly know that the PEP 1004 has been successfully released. After the ESS 1003 of the station control room is set to the "go" position, the ATP 300 may be resumed and the audible alarm turned off and all emergency stop lights removed, prompting the operator to operate the train normally.

Furthermore, in another embodiment, referring to fig. 5, after the immediately stopping scene is that the ESS contact is switched to a stop position, and the PEP contact is maintained to be closed, the electronic interlock device control 1001 performs a light alarm on the first immediately stopping indicator light, and further includes:

When the ESS contact is switched to the unset state and the PEP contact is maintained to be closed, the all-electronic interlock device 1001 controls the first emergency stop indicator lamp to stop the light alarm; or in the case that the ESS contact is maintained in a deactivated state and the PEP contact is switched to be opened, the all-electronic interlock device 1001 controls the first emergency stop indicator lamp to maintain a light alarm.

In other words, when the ESS 1003 is switched back to the "go" bit, the system will revert to the normal state. If the PEP 1004 is pressed after the ESS 1003 is set to the "stop" bit, the system will continue to execute the third step of the audible and visual alarm control logic one, but when the PEP 1004 is operated, there will be no corresponding audible alarm.

According to the emergency stop control method provided by the invention, the process actions of the corresponding audible and visual alarm control logic I of the related close stop scene I or the corresponding audible and visual alarm control logic II of the close stop alarm scene II are completed according to the specific scene, so that the safety of the system is ensured, and when each audible and visual alarm control logic is executed, the outdoor ESS 1003 and the indoor PEP 1004 are mutually clamped and controlled, so that the whole emergency stop process is safer.
