[0050] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0051] The fully automatic operation system features driverless functions, is designed according to the operation of unattended trains, aims to improve the safety and efficiency of the whole system, realizes the coordination of various related systems for train operation and the cooperation between humans and machines, and ensures the safe and efficient operation of the whole process of train operation.

[0052] With the wide application of the fully automatic operation system, fully automatic operation areas have been divided in the parking lot and depot; there are often personnel operations on the boarding platform. At present, the fully automatic yard can only use the personnel protection switch SPKS to block the track area of the storage line, and then the staff can operate on the boarding platform. However, at this time, the route cannot be established. If a train needs to depart, the staff needs to exit the track area of the storage line and turn off the SPKS to establish the route for departure, resulting in cumbersome operations and more time consumption.

[0053] In order to solve the above technical problems, when the driverless train formation is to move on the storage line, the present invention uses an acoustic-optic alarm method to prompt the staff on the boarding platform to pay attention to safety and stay away from the platform edge, so as not to affect train operation and the normal operations of the staff.

[0054] Figure 1 It is one of the schematic flowcharts of the acoustic-optic alarm method provided by the present invention. The present invention provides an acoustic-optic alarm method, including:

[0055] Step 101: Generate a route ID of the train running path according to user input, control the signal machine associated with the route ID to turn on after an interval of a target duration, and control the acoustic-optic alarm device associated with the route ID to turn on;

[0056] Repeat the following steps:

[0057] Step 102: When obtaining the route ID of any train running path, determine the current route state of the train running path;

[0058] Step 103, when the current route state is not idle and it is determined that there is no such section triggering the sound and light alarm on the train driving route, according to the first current position of the train, control the sound and light alarm device associated with the route ID to remain in the on state or switch from the on state to the off state;

[0059] The signal lamp associated with the route ID is used to indicate that the train travels according to the train driving route.

[0060] In step 101, when the user needs to establish a train route, the present invention generates the route ID of the train driving route through operation input in the operation room. Since the signal lamp associated with the route ID is used to indicate that the train travels according to the train driving route, in the prior art, once the route ID of the train driving route is generated, the signal lamp associated with the route ID will light up instantly, and then the train will automatically travel according to the signal lamp. In such a case, if the staff has not left the boarding platform or is still in the working state near the track, there may be potential safety hazards due to the automatic driving of the train. In the present invention, when generating the route ID of the train driving route, the signal lamp will not directly light up. Instead, a timer is set to control the signal lamp associated with the route ID to turn on after an interval of the target duration, so that the train will not start immediately but start after waiting for the target duration. To warn the staff that the train is about to depart, the present invention also controls the sound and light alarm device associated with the route ID to turn on. The sound and light alarm device is arranged near the train's travel route. Optionally, it is arranged at a prominent position that can prompt the staff to leave as soon as possible, which can be the middle position between two tracks, near the boarding platform, etc.

[0061] In step 102, during the train's travel, steps 102 to 103 will be continuously repeated to control the sound and light alarm device associated with the route ID to remain in the on state or switch from the on state to the off state, that is, adjust the on / off state of the sound and light alarm device at any time. In the present invention, it is first necessary to determine whether there is a route ID of any train driving route in the preset route group. Because in the subsequent continuous process of traversing the train driving state, the route ID will be retained or cleared according to the train's position, so in the process of continuous repeated traversal, the present invention needs to first determine whether the route ID still exists in the current preset route group. When obtaining the route ID of any train driving route, further determine the current route state of the train driving route.

[0062] Optionally, the method further includes:

[0063] When the route ID of the train's travel path cannot be obtained, the sound and light alarm device associated with the route ID is controlled to switch from the on state to the off state.

[0064] Optionally, if the route ID of the train's travel path cannot be obtained, it means that the train is traveling at this time, and the route ID of the train's travel path cannot be obtained because the current route state is in an idle state, or because the train has left the sound and light alarm trigger section and has entered the next section of the sound and light alarm trigger section, or because the train has left the target route section, etc. At this time, since the train can no longer pose a threat to the staff near the boarding platform, the sound and light alarm device can be turned off, that is, the sound and light alarm device associated with the route ID is controlled to switch from the on state to the off state. The present invention releases the alarm state by controlling the sound and light alarm device associated with the route ID to switch from the on state to the off state to prompt the staff that the dangerous state has been released.

[0065] In step 103, if it is determined according to step 102 that the current route state is not idle, and it is determined that the train travel path does not have the sound and light alarm trigger section, then it is considered that the train is passing through the target route section, or has not yet entered the target route section but is about to enter the target route section, or the train has left the target route section. The target route section is determined based on the route ID. At this time, since it is impossible to determine whether the train has left the target route section, it is necessary to further control the sound and light alarm device associated with the route ID to remain in the on state or switch from the on state to the off state based on the first current position of the train.

[0066] Optionally, the method further comprises:

[0067] When the current route state is in an idle state, the route ID of the train travel path is cleared in a preset route group.

[0068] Optionally, when the current route status corresponding to the route ID is idle, it is considered that the current route has completed the established route of the train. In order to provide accurate information to subsequent trains that are about to depart, the current route status needs to be set to idle to inform subsequent trains that may use this route. The present invention will continuously adjust the current route status corresponding to the route ID in the process of repeatedly traversing the preset route group.

[0069] The present invention protects the safety of the staff on the boarding platform by delaying the opening of the signal and driving the acoustic-optic alarm to give an alarm. When the staff on the boarding platform are working, the staff in the control room can also handle the opening of the route signal, so as to ensure that the staff for receiving and dispatching trains do not need to leave the boarding platform.

[0070] The present invention provides an acoustic-optic alarm method, device, electronic device and medium. After establishing the route, the present invention does not immediately turn on the signal machine, but controls the signal machine associated with the route ID to turn on after a target time interval, and controls the acoustic-optic alarm device associated with the route ID to turn on. As the train moves, information such as the route ID, the current route state of the train's driving path, and the position of the train is continuously obtained, so as to control the acoustic-optic alarm device associated with the route ID to remain in the on state or switch from the on state to the off state. When the driverless train is about to move on the storage line, the present invention delays the opening of the signal machine and uses the acoustic-optic alarm method to prompt the staff on the boarding platform to pay attention to safety and stay away from the platform edge, so as not to affect train operation and personnel work. It not only reduces the operation steps, reduces the time consumption, but also improves the safety of the staff during operation.

[0071] Figure 2 It is the second flow schematic diagram of the acoustic-optic alarm method provided by the present invention, and the method further includes:

[0072] Step 201, when the current route state is not idle and it is determined that there is an acoustic-optic alarm trigger section in the train's driving path, determine the second current position of the train;

[0073] Step 202, when the second current position of the train is located in the acoustic-optic alarm trigger section, control the acoustic-optic alarm device associated with the route ID to remain in the on state.

[0074] In step 201, if the current route state is not idle, it is considered that the train departure plan corresponding to the route ID has not been completed at this time, and the train may be in any stage of about to depart, in motion, or about to leave the target route section. If there is an acoustic-optic alarm trigger section in the train's driving path, it is considered that there is an induction section for triggering the acoustic-optic alarm in the train driving path associated with the route ID at this time. That is, only when the train passes through the induction section for triggering the acoustic-optic alarm can the acoustic-optic alarm be triggered. If the train has not passed through the induction section for triggering the acoustic-optic alarm, the acoustic-optic alarm device can be controlled to turn off according to the actual situation, or the acoustic-optic alarm device can be kept in the on state all the time.

[0075] When it is determined that there is an audible and visual alarm trigger section in the train running path, according to the second current position of the train, it is determined whether to clear the route ID of the train running path in the preset route group, or to control the audible and visual alarm device associated with the route ID to remain in the on state. The present invention provides an application scenario where the audible and visual alarm device is triggered when the train runs from outside the depot to the station yard, thus improving the audible and visual alarm scheme and enhancing the safety of the staff.

[0076] In step 202, when the second current position of the train is located in the audible and visual alarm trigger section, it is considered that the train is passing through the audible and visual alarm trigger section at this time, and it is necessary to control the audible and visual alarm device associated with the route ID to remain in the on state.

[0077] Optionally, the method further includes:

[0078] When the second current position of the train is not located in the audible and visual alarm trigger section, and it is determined that the train has left the audible and visual alarm trigger section and has entered the next section of the audible and visual alarm trigger section, the route ID of the train running path is cleared in the preset route group;

[0079] Otherwise, control the audible and visual alarm device associated with the route ID to remain in the on state.

[0080] Optionally, when the second current position of the train is not located in the audible and visual alarm trigger section, it is necessary to further determine whether the train has left the audible and visual alarm trigger section and has entered the next section of the audible and visual alarm trigger section. If it is determined that the train has left the audible and visual alarm trigger section and has entered the next section of the audible and visual alarm trigger section, it is determined that the train has left the current section corresponding to the route ID, so as to clear the route ID of the train running path in the preset route group. In this way, in the next repeated traversal, since the route ID of the train running path cannot be obtained, the audible and visual alarm device associated with the route ID is controlled to switch from the on state to the off state. The present invention provides a situation where the train has left the audible and visual alarm trigger section and has entered the next section of the audible and visual alarm trigger section, so as to timely adjust the on or off state of the audible and visual alarm device, improve the state switching sensitivity of the audible and visual alarm device, and enhance the working experience of the staff.

[0081] Optionally, if it is determined that the train has not left the audible and visual alarm trigger section, then the train is in the stage of not yet entering the audible and visual alarm trigger section, or is located in the audible and visual alarm trigger section. That is, it is necessary to control the audible and visual alarm device associated with the route ID to remain in the on state.

[0082] Figure 3 It is the third flow schematic diagram of the acoustic-optic alarm method provided by the present invention. The controlling the acoustic-optic alarm device associated with the route ID to maintain an on state or switch from the on state to an off state according to the first current position of the train includes:

[0083] Step 301: Based on the first current position of the train, when the train has not reached the target route section or has not left the target route section, control the acoustic-optic alarm device associated with the route ID to maintain an on state;

[0084] Step 302: When the train has left the target route section, clear the route ID of the train's travel path in the preset route group to control the acoustic-optic alarm device associated with the route ID to switch from the on state to the off state.

[0085] In step 301, when the current route state is not idle and it is determined that there is no acoustic-optic alarm trigger section in the train's travel path, the first current position of the train will be judged. Based on the first current position of the train, when the train has not reached the target route section or has not left the target route section, it is considered that the target route section is in a relatively dangerous state at this time, and the acoustic-optic alarm device associated with the route ID needs to be kept on all the time.

[0086] In step 302, if the train has left the target route section, clear the route ID of the train's travel path in the preset route group, so that when traversing the preset route group next time to check whether there is the route ID of the train's travel path, it will be determined that the route ID of the train's travel path cannot be obtained in the preset route group, and then control the acoustic-optic alarm device associated with the route ID to switch from the on state to the off state.

[0087] Through the above control scheme, the present invention realizes that when the train has left the target route section, the acoustic-optic alarm device is turned off to prompt the staff that the dangerous state has been lifted, and when the train has not reached the target route section or has not left the target route section, continuous alarm is given to prompt the staff to leave the boarding platform as soon as possible.

[0088] Figure 4 It is the working schematic diagram of the acoustic-optic alarm device provided by the present invention. Figure 4The scattered output board, the distribution cabinet, and the boarding platform are shown. Among them, according to the horizontal arrangement of the boarding platform from top to bottom, an audible and visual alarm relay is set on the scattered output board associated with each boarding platform, such as SGBJ11, SGBJ21, SGBJn1, etc. In the present invention, when the on-site train or the shunting route state is the initial locking of the route, the guiding route state is the guiding lock, and a judgment step is added in the open route signal processing function to obtain from the configuration data whether the starting signal of the open route needs to be delayed and determine the delay time, that is, determine the target duration to delay the opening of the signal.

[0089] Optionally, when processing the initial locking of the route, obtain the scattered acquisition quantities associated with the route from the configuration data: the audible and visual alarm relay number (SGBJ ID). If there is an audible and visual alarm relay number, fill this route ID into the route array that needs to set the audible and visual alarm.

[0090] Optionally, when processing the output data, add an audible and visual alarm relay processing function for the boarding platform. During the process of loop traversal, obtain the route array that needs to set the audible and visual alarm. If there is a valid route ID in the array, then judge whether there is a boarding stage audible and visual alarm trigger section for the valid route ID. If so, it is necessary to judge whether the state of this route is normal automatic unlocking or abnormal automatic unlocking and the trigger section is occupied. If either of the above two situations is included, drive the audible and visual alarm device to pull in, that is, keep the audible and visual alarm device in the on state; otherwise, judge that the train has occupied before the trigger section, and the current trigger section is in the idle state, and the next section of the trigger section is in the occupied state, then clear this route ID in the route array that needs to set the audible and visual alarm.

[0091] Optionally, if there is no trigger section, it is necessary to judge the approach section of this route, that is, whether the target route section is currently in the idle state, the target route section was in the occupied state before, and the first section inside the route is currently in the occupied state. If so, clear this route ID in the route array that needs to set the audible and visual alarm; otherwise, drive the audible and visual alarm device to pull in, that is, keep the audible and visual alarm device in the on state.

[0092] Optionally, if there is no valid route ID in the route array that needs to set the audible and visual alarm, control the audible and visual alarm device to switch from the on state to the off state, and clear this route ID when the route state is idle.

[0093] The present invention can effectively prompt the boarding platform staff to stay away from the edge of the boarding platform before the train formation moves. In combination with the sound and light alarm device, the relevant routes of the depot lines include train routes, shunting routes, and guiding routes. When the relevant routes of the depot lines are established, the routes are locked first, and after the signal opening conditions are met, the signal is opened after a certain delay. At the same time, the power relay of the sound and light alarm device on the boarding platform is driven to make the sound and light alarm device work to warn the boarding platform staff to stay away from the edge.

[0094] Optionally, the sound and light alarm device turns off the sound alarm after a certain internal delay. The sound and light alarm device is controlled by the power supply. After the train completely enters the signal inner side, the relay of the sound and light alarm power supply is stopped from being driven, and then the sound and light alarm device stops working.

[0095] Optionally, when multiple routes simultaneously requisition the same sound and light alarm device, as long as there is a relevant instruction indicating the need for alarm in one of the routes, the sound and light alarm device should alarm, and the alarm will stop only when all routes indicate that the sound and light alarm device stops working.

[0096] Optionally, the train travel path includes:

[0097] Moving from any target approach section in any track of the station yard to the section outside the station yard;

[0098] Moving from the section outside the station yard into any target approach section in any track of the station yard;

[0099] In any track of the station yard, moving from any target approach section to another target approach section;

[0100] At least one sound and light alarm device is associated with each end of the target approach section;

[0101] The sound and light alarm device is fixedly installed between any two adjacent tracks.

[0102] The present invention will describe the train travel path in detail in combination with specific application scenarios. Figure 5 This is one of the alarm scenario diagrams of the sound and light alarm device provided by the present invention. As Figure 5 shown, when the route from signal X2A to signal X2 is established, after the route is locked, the signal opening conditions need to be met: the signal still needs to ensure that signal X2A is opened after a certain delay, and the scattered output board of the execution unit controls the sound and light alarm device to start sound and light alarm. After the train completely enters the inner side of signal X2A, the scattered output board of the execution unit controls the sound and light alarm devices SG1, SG2, SG3, and SG4 to stop the light alarm.

[0103] Optionally, if the signal machine cannot be opened due to a fault, the train cannot enter the inner side of signal machine X2A normally, and the optical alarm must be maintained until the signal machine opens the permission light position and the train completely enters the inner side of the signal machine; if signal machine 2BG fails and cannot give the cleared state, the optical alarm also needs to be kept on all the time.

[0104] In Figure 5 when the train travels from section 1BG through section 1CG to section 1AG, it is necessary to check signal machine X1A. Similarly, when the train travels from section 2BG through section 2CG to section 2AG, it is necessary to check signal machine X2A; when the train travels from section 3BG through section 3CG to section 3AG, it is necessary to check signal machine X3A; when the train travels from section 4BG through section 4CG to section 4AG, it is necessary to check signal machine X4A.

[0105] As Figure 5 shown, Z1, Z2, Z3, and Z4 are all signal machines, which are stop signal machines for controlling the train to stop when traveling from right to left. In Figure 5 the shown station yard map, through a number of axle counters, the sections in the station yard are divided into three sections: BG, CG, and AG. Among them, section BG and section AG are stop sections, while section CG is a traveling section. In any track of the station yard, when traveling from one target approach section to another target approach section, it includes Figure 5 the train traveling path shown in

[0106] Figure 6 is the second alarm scenario diagram of the acoustic-optic alarm device provided by the present invention. When establishing the route from signal machine S2B to signal machine Z2, after the route is locked, it is necessary to make the signal opening condition satisfied: the signal system still needs to ensure that signal machine S2B can be opened after a certain delay. The execution unit's discrete output board controls the acoustic-optic alarm devices SG1, SG2, SG3, and SG4 to start acoustic-optic alarm, and stops the sound alarm after a certain time. At this time, the optical alarm still remains.

[0107] When the train completely enters the inner side of signal machine S2B, the execution unit's discrete output board controls the acoustic-optic alarm devices SG1, SG2, SG3, and SG4 to stop the optical alarm. If the signal machine cannot be opened due to a fault and the train cannot enter the inner side of signal machine S2B normally, the optical alarm must be maintained until the signal machine opens the permission light position and the train completely enters the inner side of the signal machine; if section 2AG or section 2CG fails and cannot give the cleared state, the optical alarm also must be kept all the time.

[0108] In Figure 6When the train travels from section 1AG through section 1CG to section 1BG, it is necessary to check signal S1B. Similarly, when the train travels from section 2AG through section 2CG to section 2BG, it is necessary to check signal S2B; when the train travels from section 3AG through section 3CG to section 3BG, it is necessary to check signal S3B; when the train travels from section 4AG through section 4CG to section 4BG, it is necessary to check signal S4B.

[0109] As Figure 6 shown, optionally, the sound and light alarm device is fixedly arranged between any two adjacent tracks. Sound and light alarms are respectively arranged at the head and tail of the boarding platform between section 1AG and section 2AG. The same applies to section 1BG and section 2BG. When the power supply of the sound and light alarm device is turned on, the sound and light alarm device starts to work. Optionally, the sound alarm can be controlled to turn off after a certain countdown time, while the light alarm continues until the power supply is disconnected. For example, between the route from section 1AG via section 1CG to section 1BG and the route from section 2AG via section 2CG to section 2BG, there are sound and light alarm devices SG1, sound and light alarm device SG2, sound and light alarm device SG3, and sound and light alarm device SG4. Another example is that between the route from section 3AG via section 3CG to section 3BG and the route from section 4AG via section 4CG to section 4BG, there are sound and light alarm devices SG5, sound and light alarm device SG6, sound and light alarm device SG7, and sound and light alarm device SG8.

[0110] Optionally, at least one sound and light alarm device is associated with each end of the target route section. For example, sound and light alarm devices SG1 and SG2 are respectively associated with the two ends of section 1BG; sound and light alarm devices SG3 and SG4 are respectively associated with the two ends of section 1AG; sound and light alarm devices SG5 and SG6 are respectively associated with the two ends of section 4BG; sound and light alarm devices SG7 and SG8 are respectively associated with the two ends of section 4AG. Through the above settings of the positions and quantities of the sound and light alarm devices, the present invention can not only reduce the quantity of the sound and light alarm devices, save costs, but also maximize the warning effect of the sound and light alarm devices on the staff.

[0111] Figure 7 is the third alarm scenario diagram of the sound and light alarm device provided by the present invention. When establishing the route from signal X2 to signal Xzr1, after the route is locked, the execution unit's scattered output board controls the sound and light alarm devices SG3 and SG4 to start sound and light alarm, and stops the sound alarm after a certain time, while the light alarm still remains.

[0112] Optionally, after the train completely enters the inner side of the signal X2, the execution unit's discrete output board controls the acoustic-optic alarm devices SG3 and SG4 to stop the optical alarm; if the signal cannot be opened due to a fault, and the train cannot normally enter the inner side of the signal X2, the optical alarm can remain on until the signal opens the permission light position and the train completely enters the inner side of the signal; if section 2AG or section 2CG fails and cannot give a cleared status, the optical alarm must also remain on all the time.

[0113] As Figure 7 shown, each line passes through switch L1, switch L2, and switch L3 respectively, and travels from any target approach section in any track of the station yard to the outer section of the station yard. If traveling from section 1BG to the outer section of the station yard, it needs to pass through signal X1A, signal X1, and signal Xzr1; if traveling from section 2BG to the outer section of the station yard, it needs to pass through signal X2A, signal X2, and signal Xzr1; if traveling from section 3BG to the outer section of the station yard, it needs to pass through signal X3A, signal X3, and signal Xzr1; if traveling from section 4BG to the outer section of the station yard, it needs to pass through signal X4A, signal X4, and signal Xzr1; if traveling from section 1AG to the outer section of the station yard, it needs to pass through signal X1 and signal Xzr1; if traveling from section 2AG to the outer section of the station yard, it needs to pass through signal X2 and signal Xzr1; if traveling from section 3AG to the outer section of the station yard, it needs to pass through signal X3 and signal Xzr1; if traveling from section 4AG to the outer section of the station yard, it needs to pass through signal X4 and signal Xzr1.

[0114] Figure 8 is the fourth alarm scenario diagram of the acoustic-optic alarm device provided by the present invention. When establishing the approach from signal SR to signal S2B, the approach is locked and the signal immediately opens. When the train presses into the specified section, such as the acoustic-optic alarm trigger section outside the depot line, the execution unit's discrete output board controls the acoustic-optic alarm devices SG3 and SG4 to start acoustic-optic alarm, and stops the sound alarm after a certain time. At this time, the optical alarm still remains on.

[0115] Optionally, after the train completely enters the parking track, the execution unit's discrete output board controls the acoustic-optic alarm devices SG3 and SG4 to stop the optical alarm; if the alarm trigger section for entering the depot fails and cannot give a cleared status, the optical alarm must also remain on all the time.

[0116] After the train passes signal machine SR and signal machine D1, it can enter any target approach section in any track of the station yard according to switch L1, switch L2, and switch L3. In an optional embodiment, the acousto-optic alarm trigger section in the present invention can be set near switch L1, switch L2, and switch L3. That is, during the process of the train traveling from outside the station yard into the station yard, the acousto-optic alarm device is not turned on, and only after passing through the acousto-optic alarm trigger section does the acousto-optic alarm device start to work. Specifically, the target approach section associated with the approach ID can be used to determine the associated acousto-optic alarm device, and the acousto-optic alarm device associated with the approach ID is controlled to switch from the off state to the on state.

[0117] Optionally, in the case of a combined approach, for example, when the combined approach in the departure direction is established as signal machine X2A to signal machine X2 to signal machine Xzr1, only the starting signal machine X2A is delayed to be opened and signal machine X2 is immediately opened after the approach is locked. The execution unit's discrete output board controls the acousto-optic alarm devices SG1, SG2, SG3, and SG4 to start acousto-optic alarm, and stops the sound alarm after a certain period of time, while the light alarm remains on.

[0118] Optionally, after the train completely enters the inner side of signal machine X2, the execution unit's discrete output board controls the acousto-optic alarm devices SG1, SG2, SG3, and SG4 to stop the light alarm. If the signal machine cannot be opened due to a fault, and the train cannot normally enter the inner side of signal machine X2, the light alarm must remain on until the signal machine opens the permission light position and the train completely enters the inner side of the signal machine; if section 2AG or section 2CG fails and cannot give the cleared state, the light alarm must also remain on all the time.

[0119] Optionally, when the combined approach in the arrival direction is established as signal machine SR to signal machine S2B to signal machine Z2, the approach signals are not delayed. When the train presses into the specified section, that is, the acousto-optic alarm trigger section outside the depot line, the execution unit's discrete output board controls the acousto-optic alarm devices SG1, SG2, SG3, and SG4 to start acousto-optic alarm, and stops the sound alarm after a certain period of time, while the light alarm remains on.

[0120] Optionally, after the train completely enters the parking track, the execution unit's discrete output board controls the acousto-optic alarm devices SG1, SG2, SG3, and SG4 to stop the light alarm. If the alarm trigger section for entering the depot fails and cannot give the cleared state, the light alarm must also remain on all the time.

[0121] Figure 9It is the fourth schematic flow chart of the acoustic-optic alarm method provided by the present invention. During the process of cyclic acoustic-optic alarm, the present invention cyclically sets an alarm route array, sets the valid route ID in the alarm route array. If a valid route ID cannot be obtained, the acoustic-optic alarm is driven to drop, that is, the acoustic-optic alarm switch is disconnected. If there is a valid route ID, it is determined whether the route state is idle. If the route state is idle, this route ID is cleared.

[0122] Optionally, if the route state is not idle, it is determined whether there is a staging acoustic-optic alarm trigger section for this route. If there is no staging acoustic-optic alarm trigger section, it is determined whether the train has left the target route section. If so, this route ID is cleared. If not, the acoustic-optic alarm is driven to pick up, that is, the acoustic-optic alarm is kept on.

[0123] Optionally, if there is a staging acoustic-optic alarm trigger section, it is further determined whether the train is located in the acoustic-optic alarm trigger section. If so, the acoustic-optic alarm is driven to pick up, that is, the acoustic-optic alarm is kept on.

[0124] Optionally, if the train is not located in the acoustic-optic alarm trigger section, it is further determined whether the train has left the trigger section and entered the next section. If so, this route ID is cleared. If not, the acoustic-optic alarm is driven to pick up, that is, the acoustic-optic alarm is kept on.

[0125] Figure 10 It is the schematic structural diagram of the acoustic-optic alarm device provided by the present invention. The present invention provides an acoustic-optic alarm device, including a control unit 1. The control unit 1 is used to generate a route ID of the train driving path according to user input, control the signal machine associated with the route ID to turn on after an interval of a target duration, and control the acoustic-optic alarm device associated with the route ID to turn on. The working principle of the control unit 1 can refer to the foregoing step 101 and will not be elaborated here.

[0126] The acoustic-optic alarm device further includes a repetition unit 2. The repetition unit 2 is used to repeatedly execute the following steps: when obtaining the route ID of any train driving path, determine the current route state of the train driving path; when the current route state is not idle and it is determined that there is no such acoustic-optic alarm trigger section in the train driving path, according to the first current position of the train, control the acoustic-optic alarm device associated with the route ID to remain in the on state or switch from the on state to the off state. The working principle of the repetition unit 2 can refer to the foregoing step 102 and step 103 and will not be elaborated here.

[0127] The signal machine associated with the route ID is used to indicate the train to drive according to the train driving path.

[0128] The present invention provides an acoustic and optical alarm method, device, electronic device and medium. After establishing a route, the present invention does not immediately turn on the signal machine, but controls the signal machine associated with the route ID to turn on after an interval of a target duration, and controls the acoustic and optical alarm device associated with the route ID to turn on. As the train moves, information such as the route ID, the current route state of the train's driving path, and the position of the train is continuously obtained, so as to control the acoustic and optical alarm device associated with the route ID to maintain the on state or switch from the on state to the off state. When an unmanned train is about to move on the storage line, the present invention delays the turning on of the signal machine and uses an acoustic and optical alarm method to prompt the boarding platform staff to pay attention to safety and stay away from the platform edge, thus not affecting train operation and personnel operation. It not only reduces the operation steps, reduces the time consumption, but also improves the safety of the staff during operation.
