[0002] With the rapid development of computer technology and equipment intelligent control technology, multiple gate groups can often be set up at the junction of restricted areas and non-restricted areas. The gate group includes multiple channels. After the user passes the verification on a channel, the door of the channel will open and the user can enter the restricted area through the channel. In some abnormal situations, it is necessary to release the doors of each channel to evacuate the users in the restricted area.

[0003] In the prior art, when the monitoring system detects an abnormal situation, it can send a release signal to the gate group. After receiving the release signal, the gate group controls the release of the doors of each channel based on the release signal.

[0034] First, the terms involved in one or more embodiments of this specification are explained.

[0035] Automatic Fare Collection system (AFC): It is based on computer, communication, network, automatic control and other technologies to realize the automatic processing of the whole process of rail transit ticket sales, ticket checking, billing, charging, statistics, clearing and management.

[0036] Automatic fare vending and checking system gate machine (automatic gate machine, AGM): The gate machine is a channel management device used to manage the flow of people and regulate the entry and exit of pedestrians. Its most basic and core function is to ensure that only one person passes at a time, and it can be used at the entrance and exit of various occasions.

[0037] Fire Alarm System (FAS): usually consists of fire detectors, regional alarm controllers, centralized alarm controllers, and linkage modules. The detectors effectively detect fires, the controllers process fire information and perform alarm control, and the linkage modules link fire-fighting devices.

[0038] Integrated Supervisory Control System (ISCS): Integrated Supervisory Control System for Urban Rail Transit, referred to as Integrated Supervisory Control System, is indispensable in the subway industry. It has the following elements: SCADA (Supervisory Control And Data Acquisition) for the rail transit industry; an open system consisting of general-purpose computers, network equipment and a large SCADA software platform that supports application and integrated development; a large hierarchical distributed system covering all operating points (control centers, stations, and vehicle bases); a system that interacts with various professional automation systems through open interfaces to build a real-time information sharing platform for line operations; a system that realizes fixed electromechanical equipment monitoring, remote dispatching, and coordinated dispatching functions of various professions.

[0039] Integrated backup panel (IBP): also known as IBP panel, placed in the integrated control room of the subway station. IBP panel consists of IBP panel, PLC (Programmable Logic Controller), human-machine interface terminal (provided and installed by other professionals), and monitoring workbench.

[0040] Layer 2 switches (SW): Layer 2 switches work at the second layer (data link layer) of the OSI (Open System Interconnection) model, so they are called layer 2 switches. The development of layer 2 switching technology has been relatively mature. Layer 2 switches are data link layer devices that can identify MAC (Media Access Control, local area network) address information in data frames, forward according to MAC addresses, and record these MAC addresses and corresponding ports in an internal address table.

[0041] Near Field Communication (NFC): is a short-range high-frequency wireless communication technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other. NFC is the integration of contactless radio frequency identification (RFID) and interconnection technology. It integrates the functions of inductive card reader, inductive card and point-to-point communication on a single chip, and uses mobile terminals to realize mobile payment, electronic ticketing and other applications.

[0042] Industrial Personal Computer (IPC): Also known as industrial control computer, it is a reinforced enhanced personal computer. It is a general term for tools that use a bus structure to detect and control production processes, electromechanical equipment, and process equipment. IPCs are generally square in shape and are connected to electromechanical equipment through various interfaces to monitor and control the operating status of electromechanical equipment.

[0043] Normally open node (NO): When the relay coil is not energized, the node in the disconnected state is a normally open node.

[0044] Normally closed node (NC): The normally closed node is the node in the closed state when the relay coil is not powered. For components such as travel switches and pressure relays, when not subject to external forces, the node in the open state is the normally open node, and the node in the closed state is the normally closed node. The so-called relay coil is not powered means that the switch that supplies power to the relay coil is in the open state, the normally open node of the relay itself is in the open state, and the normally closed node is in the closed state.

[0045] SC: Station Server.

[0046] AFC-SC: Station-level server of automatic fare collection system.

[0047] DI / DO: digital input signal / digital output signal.

[0048] UG: Release signal.

[0049] FB: Feedback signal.

[0050] PWR: power supply, also known as the power supply end.

[0051] It should be noted that in the subway automatic ticket vending and checking system (AFC), the terminal equipment facing passengers is mainly divided into automatic ticket machines, automatic ticket checking machines (automatic ticket vending and checking system gates), semi-automatic ticket machines, automatic inquiry machines, etc. Among them, the automatic ticket checking machine, hereinafter referred to as the "gate machine", is located in the subway station hall, between the paid area and the non-paid area, and is used to identify passenger information through technologies such as QR codes, NFC, and face recognition. After judgment and calculation, the door is opened to release passengers, or the door is closed to block passengers from passing.

[0052] When an emergency such as an earthquake, fire, or terrorist attack occurs, in order to evacuate passengers as quickly as possible, the gate needs to be put into emergency release mode to facilitate the rapid evacuation of passengers in the paid area. Figure 1 FIG. 1 is a schematic diagram of an emergency release process provided by an embodiment of the present specification. Figure 1 As shown, the fire alarm system (FAS) and the integrated monitoring system (ISCS) are mainly involved in the AFC emergency release. When the FAS system detects a fire, it will send a fire alarm signal to the ISCS. After the integrated backup disk (IBP disk) under the ISCS receives the fire alarm signal, it sends an emergency release signal to the automatic ticket vending and checking system (AFC). And receive feedback signals from the AFC to determine whether the emergency release signal is successfully sent. At the same time, the IBP disk can also select the manual release mode, and directly send an emergency release signal to the AFC system by touching the button switch on the disk. The device that connects the AFC system to the ISCS system is the emergency button control box, which shares a cabinet with the AFC station server. The AFC system sends an emergency release signal to the side machines of each gate group, such as Figure 1 The following is an example of a gate group including 5 channels and 1 side machine. The side machine can report the working status to the automatic ticket vending and checking system station-level server (AFC-SC) via Ethernet.

[0053] like Figure 1As shown in the figure, the emergency signals sent by the fire alarm system (FAS) to the integrated monitoring system (ISCS) are mainly in the form of normally open nodes (NO) and normally closed nodes (NC). The emergency signals sent by the integrated backup disk (IBP disk) of the ISCS system to the automatic ticket vending and checking system (AFC) are also mainly in the form of normally open nodes (NO) and normally closed nodes (NC). After forwarding through the emergency button control box of the AFC system, the two modes correspond to the gate groups of the AFC system, which are specifically manifested as high level (DC24V) effective and low level (DC0V) effective. When each channel of each gate group receives the emergency release signal from the emergency button control box in the AFC, it can enter the emergency release mode.

[0054] In one possible implementation, the emergency release signal can be in high-level effective mode. The main feature is that the emergency release signal from the emergency button control box to the gate group is 0V under normal circumstances. When the emergency button control box detects the emergency release signal from the IBP disk, it outputs DC24V. After the gate group detects DC24V, it enters the emergency release mode and unconditionally opens the doors of each channel. The advantage of the emergency release signal being in high-level effective mode is that there is basically no false triggering due to non-human factors.

[0055] However, the disadvantage of the emergency release signal being in high-level effective mode is that if the line transmitting the emergency release signal ages and becomes disconnected, or the connector becomes loose and is not discovered in time, when an emergency occurs, the emergency release signal cannot be completely sent to all channels in the gate group, causing the doors of some channels to be unable to open unconditionally and passengers in the station to be unable to evacuate effectively.

[0056] In another possible implementation, the emergency release signal can be in a low-level effective mode. The main feature is that the emergency release signal from the emergency button control box to the gate group is DC24V under normal circumstances. When the emergency button control box detects the emergency release signal from the IBP disk, it outputs DC0V. After the gate group detects DC0V, it enters the emergency release mode and unconditionally opens the doors of each channel. The advantage of the low-level effective mode is that in the normal mode, once the line transmitting the emergency release signal is accidentally disconnected or the connector is loose, the gate group cannot detect DC24V and immediately enters the emergency release mode. The line fault can be discovered and handled in time, avoiding the situation where the emergency release signal cannot be completely sent to all channels in the event of an earthquake or fire.

[0057] However, the disadvantages of the low-level effective mode of the emergency release signal are also very obvious. That is, when the line is disconnected or the connector is loose due to factors such as line aging, frequent movement of channel doors, and human collision, at least one channel or all channels in a group of gates will enter the emergency release mode without receiving the emergency release signal, which is called "false triggering". If the operating personnel do not handle it in time, it will cause passengers to panic and flee, and a large number of passengers will leave the station without scanning the code, swiping the card or scanning their face, resulting in a large number of incomplete transactions.

[0058] The embodiments of the present specification provide a gate control system, method and side machine in a gate group. For the high-level effective mode of the emergency release signal, a release feedback signal can be set in the gate group, the release feedback signal of each channel can be collected, and the release feedback signal of each channel can be cascaded to determine whether each channel of the gate group is fully and effectively opened, and use this as a judgment condition to determine whether to further forcibly disconnect the power supply of each channel door of the gate group, so as to achieve the action of unconditionally releasing the channel doors in the gate group in an emergency even if the line is disconnected or the connector is loose.

[0059] At the same time, since the forced power off of the door will cause the communication between the door control unit in the channel and the main control unit (i.e., the industrial computer) to be interrupted, the main control unit will report the fault of the door communication interruption in this channel to the station server. The station server can determine whether the power is off for the entire group of channel doors at the same time by analyzing the fault information of the main control units of each channel, and further infer that the emergency release signal line in this group of channels is disconnected or the connector is loose, and record the fault log, thereby reducing the scope of subsequent troubleshooting.

[0060] As can be seen from the above, the embodiments of this specification can not only solve the problem that the channels of the gate cannot be completely released when an emergency occurs due to line failure in the high-level effective mode, but also avoid the "false triggering" failure of the emergency release signal caused by line aging or loose connectors in the low-level effective mode. In addition, due to the cascade signal, the door is forced to be powered off and the communication is interrupted. Through the judgment of the station server, the line fault judgment range is narrowed to a certain channel, which is convenient for subsequent analysis of the cause and timely maintenance.

[0061] In this specification, a gate control system is provided. This specification also involves a gate control method, a side machine in a gate group, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0062] See also Figure 2 , Figure 2 FIG. 1 shows a schematic diagram of a gate control system according to an embodiment of the present specification. Figure 2 As shown, the gate control system includes at least one gate group 1, the gate group 1 includes a side machine 2 and at least one channel 3; the side machine 2 is equipped with a release unit 21, a delay unit 22 and a feedback unit 23; the channel 3 is equipped with a leaf door control device 31 and a release feedback device 32, the leaf door control device 31 is used to release the leaf door, and the release feedback device 32 is used to indicate the release state of the leaf door;

[0063] The release unit 21 is respectively connected to the door control device 31, the delay unit 22 and the feedback unit 23, the delay unit 22 is connected to the power supply terminal 4 of the door control device 31, and the feedback unit 23 is connected to the release feedback device 32;

[0064] The feedback unit 23 is configured to control the delay unit 22 to stop timing when each release feedback device 32 indicates that the door is successfully released. The delay unit 22 is configured to disconnect the power supply terminal 4 of the door control device 31 when the timing reaches a set time.

[0065] Among them, the gate control system can control at least one gate group, and the at least one gate group can be set at the junction of the restricted area and the unrestricted area. Each gate group can include a side machine and at least one channel. The number of gate groups and the number of channels in each gate group can be configured based on actual conditions. The side machine is responsible for the power distribution, network distribution, and forwarding of release signals of each channel in this gate group, so as to realize the management and control of each channel in this gate group. There are doors in the channel. Usually, the doors in the channel are closed, which are used to restrict users from entering and exiting the restricted area. Users are verified in a certain channel. After the verification is passed, the doors of the channel will open, and users can enter and exit the restricted area through the channel. For example, in the scenario of taking the subway, the user touches the NFC device area of ​​the channel with a mobile phone, and uses NFC technology to realize fee deduction and verification.

[0066] As an example, Figure 1 As shown, the gate control system can control N gate groups, each gate group is equipped with X channels and a side machine, so there are a total of N*X channels in the station. If N=4, X=5, there are 4*5=20 channels for users to pass between restricted areas and non-restricted areas.

[0067] In actual implementation, the side machine is equipped with a release unit, a delay unit and a feedback unit. The release unit is used to control each channel to release the door, that is, to open the door in the channel; the delay unit is used to achieve delayed power off to force the release of the door of each channel; the feedback unit is used to control the timing of the delay unit based on the release state of the door. Among them, the release state of the door is used to indicate whether the door is successfully released, that is, the release state of the door is a release feedback signal that feedbacks whether the door is successfully released. The release state of the door includes the door being successfully released and the door not being released.

[0068] In addition, in order to disconnect the power supply end of the door control device, that is, to release the door, a door mechanical structure needs to be configured so that the door can open automatically after power failure.

[0069] Specifically, the release unit is connected to the door control device of each channel on one path, thereby controlling each channel to release the door; the other path is connected to the delay unit, and the delay unit is used to perform timing. When the delay unit timing reaches the set time, the power supply end of the door control device of each channel is controlled to be disconnected, so as to forcibly cut off the power of the door of each channel and release the door; the other path is connected to the release feedback device of each channel, and the release feedback device can indicate the release status of the door of the channel, such as the door is successfully released, the door is not released, etc. When each release feedback device indicates that the door is successfully released, it means that each channel in the gate group has successfully opened the door. At this time, the feedback unit can control the delay unit to stop timing, and the delay unit will no longer operate, and will not disconnect the power supply end of the door control device, and the power supply is normal. Among them, the set time is a pre-configured delay time for forced power off, and the set time can be configured based on actual needs.

[0070] In the embodiments of the present specification, the release feedback signal of each channel can be collected to determine whether each channel of the gate group has successfully released the door, and this can be used as a judgment condition to determine whether to forcibly disconnect the power supply end of the door control device for each channel of the gate group. In this way, in an emergency, even if the line is disconnected or the connector is loose, each channel in the gate group can release the door, avoiding missing of certain channels without releasing the door, thereby ensuring the accuracy of the release control.

[0071] In an optional implementation of this embodiment, Figure 2 As shown, the release unit 21 is connected in parallel to the door control device 31 of each channel 3;

[0072] The release unit 21 is configured to transmit a release signal to the door control device 31 of each channel 3 when receiving the release signal, wherein the release signal is a high level signal;

[0073] The door control device 31 is configured to release the door of the corresponding channel when receiving a release signal.

[0074] The release signal is a control signal received under certain abnormal circumstances, and the release signal is used to control each channel to release the door.

[0075] Among them, the high level signal can be DC24V.

[0076] It should be noted that in some abnormal situations, it is necessary to release the doors of each channel to evacuate users in the restricted area, such as in the event of an earthquake, fire, terrorist attack or other emergency. When the release unit receives the release signal, it is connected in parallel to the door control device of each channel to transmit the release signal to the door control device of each channel. When the door control device of each channel receives the release signal, it enters the release mode and can control the release of the door of the corresponding channel.

[0077] In actual implementation, the release signal can be sent by the AFC emergency button control box. Specifically, the integrated monitoring backup disk has the function of sending a release signal to the AFC emergency button control box, and the AFC emergency button control box forwards the received release signal in the form of high level (DC24V) or low level (low level) to at least one gate group under control.

[0078] In the embodiment of the present specification, the release unit is connected in parallel to the door control device of each channel to prevent the abnormality of the line of one channel from failing to receive the release signal and affecting other channels from receiving the release signal. The release signals transmitted to the door control units of each channel do not affect each other, thereby ensuring the success rate of the release signal transmission.

[0079] It should be noted that, taking the subway station as an example, the ISCS system's IBP button sends the release signal to the AFC system in two main modes: normally open node (NO) and normally closed node (NC). After forwarding through the AFC system emergency button control box, the two modes correspond to the gate group of the AFC system, which is specifically manifested as high-level signal (DC24V) and low-level signal (DC0V).

[0080] In actual implementation, for low-level signals as release signals, there may be a situation in normal mode where, once the line transmitting the release signal is accidentally disconnected or the connector is loose, the gate group cannot detect the high-level signal, and immediately enters the release mode to release the door, which may cause false triggering, panic and loss. Therefore, in actual implementation, a high-level signal can be used as the release signal, that is, after the AFC emergency button control box is configured to receive the release signal from the integrated monitoring backup disk, the release signal is forwarded to each gate group in the form of a DC24V high-level signal.

[0081] Specifically, the door control device can be configured to respond to the release mode as a high-level signal, that is, the normal signal received by the normal mode door control device is a low-level signal (DC0V). When a high-level signal (DC24V) is received, it responds to enter the release mode and controls the release of the door.

[0082] A special high-level mode is provided in the embodiments of the present specification, and the release signal is a high-level signal. By using a delay unit and a feedback unit, in an emergency, even if the line is disconnected or the connector is loose, each channel in the gate group can release the door, avoiding missing of certain channels and failing to release the door, thereby ensuring the accuracy of the release control. It can not only solve the problem that the door cannot be completely released when an emergency occurs due to line failure in the conventional high-level mode, but also avoid the "false triggering" failure of the emergency signal caused by line aging or loose connectors in the low-level mode.

[0083] In an optional implementation of this embodiment, Figure 2 As shown, the delay unit 22 includes a delay relay 221, and the delay relay 221 includes a delay primary switch 2211 and a delay secondary switch 2212. The delay secondary switch 2212 is connected in series to the power supply terminal 4 of the door control device 31 of each channel 3, and the delay secondary switch 2212 is a normally closed node; the feedback unit 23 is connected to the delay primary switch 2211 to control the timing work of the delay primary switch 2211;

[0084] The time-delay primary switch 2211 is configured to drive the time-delay secondary switch 2212 to be turned off when the timing reaches a set time.

[0085] In actual implementation, the second path of the release unit is connected to the delay unit to transmit a release signal to the delay unit. The delay unit includes a delay relay, and the delay relay includes a delay primary switch and a delay secondary switch. The delay secondary switch is connected in series to the upstream of the power supply end of the door control device of each channel, so as to ensure that the power supply end of the door control device of each channel can be disconnected together. The delay secondary switch is a normally closed node to ensure that the power supply end of the door control device of each channel is powered normally under normal circumstances. The delay primary switch is equipped with a timing function. When the delay unit receives the release signal, the delay primary switch starts timing. When the timing reaches the set time, the delay primary switch can drive the delay secondary switch to disconnect, thereby disconnecting the power supply end of the door control device of each channel.

[0086] In addition, the delayed primary switch is connected to the feedback unit, and the feedback unit can control whether the timing function of the delayed primary switch continues to time, thereby controlling whether to forcibly disconnect the power supply end of the door control device of each channel based on the feedback unit.

[0087] In the embodiment of this specification, the feedback unit collects the release feedback signal of each channel, controls whether the delay primary switch of the delay relay continues to time, and uses the timing result to drive the delay secondary switch to disconnect, so that in an emergency, even if the line is disconnected or the connector is loose, each channel in the gate group can release the door, avoiding missing some channels and not releasing the door, ensuring the accuracy of the release control. In addition, the delay relay is used to create a buffer time for the time difference of the release action of multiple channels, and the power is forced to be cut off when the timing reaches the set time to avoid false action.

[0088] In an optional implementation of this embodiment, Figure 2 As shown, the feedback unit 23 is connected in series to the release feedback device 32 of each channel 3; the door control device 31 is equipped with a first feedback relay 311, and the release feedback device 32 is a normally open node;

[0089] The door control device 31 is configured to drive the first feedback relay 311 to work when receiving the release signal, and drive the normally open node to close through the first feedback relay 311;

[0090] The feedback unit 23 is configured to determine that the door is successfully released when the normally open nodes of each channel 3 are closed to form a loop, and control the delay unit 22 to stop timing.

[0091] It should be noted that the third path of the release unit is connected to the feedback unit. When each door control device receives the release signal, it will unconditionally open the door and drive the first feedback relay to work. The first feedback relay can drive the normally open node (i.e., the release feedback device) in this channel to close, so as to form a loop for the release feedback signals of each channel in this group. When the feedback unit detects that the normally open nodes of each channel are closed to form a loop, it means that the doors of each channel have been successfully released. At this time, the control delay unit stops timing and no longer performs forced power off. The release feedback devices configured in each channel are connected in series, that is, the normally open nodes are connected in series, to determine whether any of the multiple channels has failed to release the door as expected, and take further forced power off measures.

[0092] In actual implementation, the positive end of the release unit is connected to the positive end of the feedback unit, and the negative end is cascaded to the normally open nodes of each channel in this group, and then connected to the negative end of the feedback unit. In this way, when the normally open nodes of each channel in this group are closed to form a loop, the positive and negative ends of the feedback unit form a loop, the feedback unit is powered to work, and the control delay unit stops timing.

[0093] In the embodiment of the present specification, if before the time delay relay is completed, each channel in the group has completed the door release and driven the first feedback relay to work, then the normally open nodes of each channel in the group can form a loop, the feedback unit is powered on and can work, the delay relay is powered off and stops timing, and cannot complete the power-off action, and the door control device of each channel can maintain normal power supply. When the door control unit of any channel in the group has circuit aging, loose connectors, etc., resulting in it being unable to receive the release signal normally and unable to open the door as required, it cannot drive the corresponding first feedback relay to work, then the normally open nodes in each channel of the group cannot be completely closed, and a loop cannot be formed, the feedback unit cannot be powered, that is, the delay unit cannot be controlled, and the delay unit continues to time, reaching the set time length, and forced power off is achieved. The door is forced to open due to abnormal power failure, which also has the effect of releasing passengers, solving the problem of being unable to completely release the door when a real emergency occurs due to line failure, and improving the control accuracy.

[0094] In an optional implementation of this embodiment, Figure 2 As shown, the feedback unit 23 includes a second feedback relay 231, and the second feedback relay 231 includes a feedback primary switch 2311 and a feedback secondary switch 2312; the feedback primary switch 2311 is connected in series to the normally open node of each channel (that is, the release feedback device 32), and the feedback secondary switch 2312 is connected to the delay primary switch 2211, and the feedback secondary switch 2312 is a normally closed node;

[0095] The feedback primary switch 2311 is configured to determine that the door is successfully released when the normally open nodes of each channel 3 are closed to form a loop, and drive the feedback secondary switch 2312 to open. When the feedback secondary switch 2312 is opened, the delay primary switch 2211 is powered off and the timing is stopped.

[0096] The second feedback relay may be a small DC relay.

[0097] In actual implementation, the feedback unit includes a second feedback relay, and the second feedback relay includes a feedback primary switch and a feedback secondary switch. The feedback primary switch is connected in series to the normally open node of each channel, and the feedback secondary switch is connected to the delay primary switch. The feedback secondary switch is a normally closed node, which can ensure that the delay primary switch is normally powered when the feedback primary switch is not actuated, thereby realizing delay timing. When the normally open nodes of each channel are closed to form a loop, the feedback primary switch is powered and works normally, driving the feedback secondary switch to disconnect. When the feedback secondary switch is disconnected, the delay primary switch is powered off and the timing stops.

[0098] In the embodiment of the present specification, the third path of the release signal of the release unit is connected to the second feedback relay, the positive end of the release signal is connected to the positive end of the feedback primary switch of the second feedback relay, and the negative end of the release signal is connected to the negative end of the feedback primary switch of the second feedback relay after cascading the normally open nodes of each channel in this group. When the normally open nodes of each channel in this group are closed to form a loop, the negative end of the release signal can be connected to the feedback primary switch of the second feedback relay, the feedback primary switch can be activated, and the delay primary switch of the delay relay is powered off. The feedback primary switch of the second feedback relay is used to drive the feedback secondary switch, and the feedback secondary switch is used to control whether the delay primary switch continues to time. In this way, the second feedback relay is used to determine whether each channel in this group has been successfully released. If any channel fails to be released, the power supply of the door control device is automatically cut off within the specified time, further ensuring that the door control unit can release the door and ensure the reliability of the release.

[0099] In an optional implementation of this embodiment, Figure 2 As shown, the gate control system also includes a working server 5, and the side machine 2 is also equipped with a communication unit 24; the channel 3 is also equipped with an industrial computer 33, and the industrial computer 33 is connected to the door control device 31;

[0100] The industrial computer 33 is configured to obtain the working status of the door control device 31 and transmit the working status to the communication unit 24;

[0101] The communication unit 24 is configured to receive the working status transmitted by the industrial computer 33 of each channel 3 in the gate group, and report the working status to the working server 5;

[0102] The working server 5 is configured to receive and store the working status reported by at least one gate group 1 .

[0103] In actual implementation, the communication unit may be a layer 2 switch. An industrial computer may be configured in each channel, and the industrial computer may be connected to the door control unit. The industrial computer may obtain the working status of the door control device and report it to the communication unit of the side machine. The working status may be information indicating the current working of the door control device, such as normal status and release status. The normal status is used to indicate that each channel is working normally, and the release status is used to indicate that the door is released successfully. Specifically, the door control device may report the working status to the industrial computer through a serial communication line.

[0104] In addition, if the power supply to the door control device is cut off, the communication between the door control device and the industrial computer will be abnormally interrupted, so the working status obtained by the industrial computer may also include an abnormal interruption status, which is used to indicate that the door control unit is abnormally powered off.

[0105] In the embodiments of this specification, the industrial computer can obtain the working status of the door control device of each channel in the group and report it to the working server. The working server can store the working status reported by each gate group and establish an operation log of each gate group, so as to facilitate subsequent search, positioning, abnormality analysis and other operations.

[0106] In an optional implementation of this embodiment, the working server 5 is further configured to locate an abnormal gate group based on the working status reported by at least one gate group 1.

[0107] In the subway scenario, the working server may be an automatic ticket vending and checking system station-level server AFC-SC.

[0108] It should be noted that after the door control device is powered off abnormally, its communication with the industrial computer is interrupted. At this time, the working status reported by the industrial computer to the working server is an abnormal interruption state. When the working server receives the abnormal interruption state reported by each channel of a certain gate group at the same time, and the remaining gate groups report the release state, it can be predicted that there is a possibility of abnormality in the gate group, and its log can be retained for subsequent analysis. That is, based on the working status reported by at least one gate group, the working server can determine whether there is an abnormality and locate the abnormal gate group.

[0109] In the embodiment of this specification, when the working server simultaneously receives abnormal interruption status uploaded by each channel in a certain group of gate groups, while the other groups of gate groups do not upload abnormal interruption status, it can be used as a basis for judging that the release signal of this group of gate groups has aged, loosened, or fallen off, and can be used for subsequent analysis and troubleshooting.

[0110] In an optional implementation of this embodiment, each channel may also be equipped with an audible and visual alarm device, such as a buzzer, an indicator light, etc. When the door control device receives a release signal and enters a release mode, after controlling the door to be released, the audible and visual alarm device of the corresponding channel may be controlled to sound an alarm. In addition, each channel may also be equipped with a display screen, an indicator, or other guiding device. After the door control device releases the door, evacuation information may be displayed on the display screen, an indicator, or other guiding device to prompt the user to evacuate. Furthermore, evacuation information may be displayed on a public display screen in a restricted area and / or non-restricted area, with the evacuation direction displayed in the restricted area and a no-entry sign displayed in the non-restricted area, so as to quickly guide and evacuate users.

[0111] In an optional implementation of this embodiment, the gate control system further includes a working server 5;

[0112] The working server 5 is configured to determine the target user located in the restricted area upon receiving the evacuation signal, and push evacuation prompt information to the terminal held by the target user.

[0113] The evacuation prompt information may be information to guide users to leave the restricted area in time, such as "an emergency has occurred, please leave quickly". In addition to text prompts, the evacuation prompt information may also be a voice prompt, so that the terminal held by the target user automatically plays the evacuation prompt information.

[0114] It should be noted that when entering the restricted area, each user needs to be verified in the channel. Only after the verification is passed, the door of the channel will open and the user can enter the restricted area. Therefore, after the user passes the verification and the door is opened, the channel can also report the user's terminal information to the work server. When an abnormal situation occurs and evacuation is required, the work server can determine the user who has passed the verification, that is, the target user in the restricted area, and push evacuation prompt information to the target user's terminal to avoid the target user being far away from the gate group and unable to be informed of the emergency situation, including the target users in the restricted area can be evacuated in time.

[0115] For example, when taking the subway, users can scan the code on the mini program homepage to enter the station. In the event of an emergency, the work server can push a message "An emergency has occurred, please leave quickly" to the mobile phone that has scanned the code, so that the mobile phone will display the evacuation reminder information on the mini program homepage.

[0116] In an optional implementation of this embodiment, Figure 2 As shown, the gate control system also includes a control terminal 6;

[0117] The control terminal 6 is configured to obtain the current location of the terminal held by the target user based on the working server 5; determine whether there are any unevacuated users based on the current location, and if so, display the location and route guidance of the unevacuated users.

[0118] It should be noted that after the working server pushes the evacuation prompt information to the terminals of the target users in the restricted area, some target users may not see the evacuation prompt information in time, resulting in their failure to evacuate in time. Therefore, the gate control system also includes a control terminal, which can be held by a staff member. The control terminal can obtain the current location of the terminals of each target user, and determine whether there are any unevacuated users still in the restricted area based on the current location. If so, the location and route guidance of the unevacuated users can be displayed on the control terminal, so that the staff can quickly go to the location of the unevacuated users and guide the users to evacuate in time.

[0119] The gate control system provided in the embodiments of this specification can use the delay unit to force power off the gate group when certain abnormal situations occur, even if any channel release signal line fails such as aging, falling off, loosening, etc., to ensure that the doors of each channel are released and no channel is missed; if the doors of each channel of the gate group are successfully released, the timing will stop to avoid abnormalities caused by forced power off, thereby greatly improving the control accuracy of the gate group.

[0120] It should be noted that the gate control solution provided in the embodiments of this specification can be applied to urban rail transit scenarios such as subways, railway stations, high-speed railway stations, airports, etc., or can also be applied to life scenarios such as supermarkets, cinemas, concerts, etc., and the embodiments of this specification do not limit this.

[0121] Figure 3 This is a schematic diagram of the structure of a gate group provided by an embodiment of this specification, taking a high-level signal DC24V as a release signal, and illustrating the application in a subway scenario as an example. Figure 3 The figure shows a gate group. After the release unit in the gate receives the DC24V signal from the AFC emergency button control box, it divides the DC24V signal into three paths.

[0122] The first DC24V-1 signal is the release signal UG within this gate group. The UG signal is connected in parallel to each channel within this gate group and connected to the emergency release function input interface of the door. When each emergency release function input interface receives the release signal UG, the door is opened unconditionally.

[0123] After the door is successfully opened, the feedback relays A1~A5 are driven to operate and the normally open nodes in this channel are closed, so as to form a loop for the release feedback signals of each channel in this gate group.

[0124] At the same time, the door uploads the working status as released through the communication line with the industrial computer, and reports the released status to the layer 2 switch of the side machine through the industrial computer, and then reports it to the station server through Ethernet, indicating that an emergency has occurred. And other DI / DO interfaces drive the buzzer and passenger warning lights to work, and give sound and light alarms.

[0125] When the industrial computer receives the working status reported by the door control device as released, it displays "Please evacuate quickly" and other information on the passenger display screen. At the same time, the passage indicator on the channel and the guide screen on the ceiling of the station hall display green arrows in the paid area and red no-entry signs in the non-paid area to quickly guide and evacuate passengers. The layer 2 switch in the side machine uploads the current emergency status of the station hall to the station server through Ethernet.

[0126] The second DC24V-2 signal is connected to a delay relay K1. The secondary switch of K1 is a normally closed node, which is serially connected to the upstream of the power supply end (PWR) of the door control device of each channel. The primary switch of K1 has a timing function. If the primary switch of K1 is powered on and the timing reaches the set time, the primary switch of K1 will be activated to drive the secondary switch of K1 to disconnect. Each door control device in this gate group will be forced to power off. After the door control device loses power, the door will automatically open. The positive end of DC24V-2 (DC24V-2+) is connected to the primary switch of K1, and the negative end of DC24V-2 (DC24V-2-) is connected to the secondary switch of K2.

[0127] The third DC24V-3 signal is connected to a small DC relay K2. The positive end of DC24V-3 (DC24V-3+) is connected to the positive end of the primary switch of K2, and the negative end of DC24V-3 (DC24V-3-) is connected to the negative end of the primary switch of K2 after cascading the normally open nodes of each channel in this gate group, forming a feedback loop to transmit the feedback signal FB of whether the door is released. When the normally open nodes of each channel in this gate group are closed to form a closed loop, the negative end of DC24V-3 can be connected to the primary switch of K2, and the primary switch of K2 is powered, executed, and drives the secondary switch of K2 to open.

[0128] The secondary switch of K2 is a normally closed node, which is used to control the primary switch of the delay relay K1. That is, when the primary switch of K2 is actuated, the secondary switch of K2 is disconnected, the primary switch of K1 is powered off, the primary switch of K1 cannot continue timing, the secondary switch of K1 does not actuate, and forced power off is not performed.

[0129] If all the door control devices in this gate group complete the door release before the delay relay K1 completes the timing, and outputs to their respective feedback relays A1~A5, then the normally open nodes of each channel of this gate group can form a closed loop, and the positive and negative power supply of the K2 primary switch is normal and can be operated. After the K2 primary switch is operated, the K2 secondary switch is disconnected, the K1 primary switch is powered off, and K1 stops timing, and the power supply to the door control devices of each channel cannot be cut off. The door control devices of each channel can maintain normal power supply, and the door control devices can work normally with normal power supply, receive the release signal normally, and drive the door to open to evacuate passengers.

[0130] When any channel of this gate group has circuit aging or connector looseness, it cannot receive the release signal normally and cannot open the door as required, and cannot drive one of the five feedback relays A1 to A5 to operate. Then the normally open nodes of each channel in this gate group cannot form a closed loop. After the release signal is sent, the third DC24V-3 signal cannot be provided to the primary switch of K2, and K2 cannot operate.

[0131] If K2 has not acted before the time delay relay K1 is finished, the primary switch of K1 will be powered normally. When the time is up, the secondary switch of K1 will act immediately to disconnect the power supply of the door control devices of each channel in this gate group. The doors of each channel are forced to open due to abnormal power failure, which also has the effect of evacuating passengers.

[0132] In the embodiments of the present specification, it can be ensured that in emergency situations such as earthquakes, fires, terrorist attacks, etc., even if the release signal line is aged, fallen off, or loose, the channel doors of all gate groups in the station hall can be reliably opened, and false alarms of emergency signals due to aging, falling off, and loosening of the lines are avoided, which leads to accidental opening of the doors, causing passengers to panic and flee due to false emergency alarms, resulting in incomplete transactions.

[0133] Figure 4 A flow chart of a gate control method provided according to an embodiment of the present specification is shown, which is applied to a side machine included in any gate group in a gate control system, the gate group also includes at least one channel, the channel is equipped with a leaf door control device and a release feedback device, the release feedback device is used to indicate the release status of the leaf door; the method specifically includes the following steps.

[0134] Step 402: receiving a release signal, and transmitting the release signal to the door control device of each channel, wherein the release signal is used to instruct the door control device to release the door.

[0135] Step 404: Start timing, and stop timing if the timing does not reach the set time and each release feedback device indicates that the door is successfully released.

[0136] Step 406: When the timing reaches the set time, the power supply end of the door control device of each channel is disconnected.

[0137] It should be noted that the gate control method provided in the embodiment of this specification is implemented by using the circuit connection and mechanical structure of the release unit, delay unit and feedback unit in the side machine, that is, the hardware structure is used in the side machine to realize the delay timing and forced power off. Of course, in practical applications, corresponding software function modules can also be set in the side machine to realize the delay timing and forced power off through software control, and the embodiment of this specification does not limit this.

[0138] The gate control method provided in the embodiment of this specification is that when the side machine receives the release signal, it controls each channel to release the leaf door and starts timing. If the timing does not reach the set time and each release feedback device indicates that the leaf door is successfully released, it means that the leaf doors of each channel in the gate group are successfully released and there is no need to force power off. At this time, the timing is stopped and the forced power off action is no longer performed. If the timing is not stopped, when the timing reaches the set time, it means that the leaf door of a certain channel has not been successfully released. At this time, the power supply end of the leaf door control device of each channel can be disconnected, and the leaf door control device automatically opens after power failure. In this way, if the leaf door of any channel of the gate group is not successfully released, the delayed timing can be used to force power off the gate group to ensure that the leaf doors of each channel are released and no channel is missed; if the leaf doors of each channel of the gate group are successfully released, the timing will be stopped to avoid abnormalities caused by forced power off, thereby greatly improving the control accuracy of the gate group.

[0139] The above is a schematic scheme of a gate control method of this embodiment. It should be noted that the technical scheme of the gate control method and the technical scheme of the gate control system described above are of the same concept, and the details of the technical scheme of the gate control method that are not described in detail can be found in the description of the technical scheme of the gate control system described above.

[0140] The following combination Figure 5 , taking the application of the gate control method provided in this specification in the subway scenario as an example, the gate control method is further explained. Figure 5 A process flow chart of a gate control method provided by an embodiment of this specification is shown, such as Figure 5 The figure shows the emergency release process of a gate group. The integrated monitoring system sends an emergency release signal. After the side machine receives the emergency release signal, it transmits the emergency release signal to each channel, delay relay, and feedback relay. Each channel receives the release signal and the door opens. In addition, the delay relay starts timing when it receives the release signal.

[0141] The feedback relay determines whether each channel has successfully released the fan door. If so, the feedback relay is disconnected, and then the delay relay is controlled to power off and stop timing. The fan doors of each channel are powered normally and the fan doors open. If not, the feedback relay is closed and the delay relay continues timing. When the timing time is up, the delay relay is disconnected, the fan door is forced to be powered off, and the fan door opens.

[0142] In the embodiment of this specification, a release feedback signal is set in the gate group, and the release feedback signals of each channel are collected and cascaded to determine whether each channel of the gate group is fully and effectively opened. This is used as a judgment condition to determine whether to further forcibly disconnect the power supply of each channel door of the gate group, so that in an emergency, even if the line is disconnected or the connector is loose, the door of each channel in the gate group can still be released unconditionally. If the doors of each channel of the gate group are successfully released, the timing will stop to avoid abnormalities caused by forced power off, thereby greatly improving the control accuracy of the gate group.

[0143] Corresponding to the above method embodiment, this specification also provides an embodiment of a side machine in a gate machine group. Figure 6 FIG. 1 shows a schematic diagram of the structure of a gate machine in a gate machine group provided by an embodiment of the present specification. Figure 6 As shown, the gate group also includes at least one channel, the channel is equipped with a door control device and a release feedback device, the release feedback device is used to indicate the release state of the door, and the side machine includes:

[0144] The transmission module 602 is configured to receive a release signal and transmit the release signal to the door control device of each channel, wherein the release signal is used to instruct the door control device to release the door;

[0145] The stop timing module 604 is configured to start timing, and stop timing when the timing does not reach the set time and each release feedback device indicates that the door is successfully released;

[0146] The power-off module 606 is configured to disconnect the power supply end of the door control device of each channel when the timing reaches a set time.

[0147] The side machine in the gate group provided in the embodiment of the present specification includes a transmission module, a stop timing module, and a power-off module. By using the interactive configuration of the three modules, when the side machine receives a release signal, it controls each channel to release the leaf door and starts timing. If the timing does not reach the set time and each release feedback device indicates that the leaf door is successfully released, it means that the leaf doors of each channel in the gate group are successfully released and there is no need to force power off. At this time, the timing is stopped and the forced power off action is no longer performed. If the timing is not stopped, when the timing reaches the set time, it means that the leaf door of a certain channel has not been successfully released. At this time, the power supply end of the leaf door control device of each channel can be disconnected, and the leaf door control device automatically opens after power failure. In this way, if the leaf door of any channel of the gate group is not successfully released, the delayed timing can be used to force power off the gate group to ensure that the leaf doors of each channel are released and no channel is missed; if the leaf doors of each channel of the gate group are successfully released, the timing will be stopped to avoid abnormalities caused by forced power off, thereby greatly improving the control accuracy of the gate group.

[0148] The above is a schematic scheme of a side machine in a gate group of this embodiment. It should be noted that the technical scheme of the side machine in the gate group and the technical scheme of the gate control system described above are of the same concept, and the details of the technical scheme of the side machine in the gate group that are not described in detail can all be referred to the description of the technical scheme of the gate control system described above.
