Technical Field

[0001] The present invention belongs to the technical field of access control systems, and in particular relates to an access control system suitable for coupling multiple carriages. Background Art

[0002] With the rapid development of urbanization, rail transit, as a kind of urban transportation with large carrying capacity and fast delivery capability, has been integrated into people's lives more and more rapidly in recent years. Rail transit vehicles have also evolved into many varieties, such as subways, trains, light rails and maglev trains. While facilitating the travel of urban residents, some problems have gradually been exposed.

[0003] With the advancement of technology, access control has gradually changed from traditional purely mechanical door locks to electronic locks controlled by electric and electronic methods. This electronic lock controls the door lock through electrical signals to a locked state where the door cannot be opened or an unlocked state where the door can be opened. However, in rail transit, the operating vehicle has multiple carriages, corresponding to multiple doors. The existing technology makes it difficult to achieve remote unlocking, remote status control, and remote video intercom of multiple doors when multiple carriages are reconnected. Moreover, the platform heights of different stations may be different. When the platform is low, people outside the vehicle have to climb the ladder to complete access control calls, video intercoms, etc. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and to provide a door access control system for the reconnection of multiple carriages, which can remotely unlock multiple doors, remotely monitor the status, and remotely perform video intercom when multiple carriages are reconnected. Moreover, regardless of the height of the platform, people outside the car can complete door access calls, video intercoms, etc. without climbing the ladder.

[0005] The first aspect of the present invention is to provide an access control system suitable for the reconnection of multiple carriages, including: a switch, which is arranged in each carriage, and the switches on two adjacent carriages are connected through a reconnection harness; an access control host, which is arranged in a duty room and a command room, and which exchanges data with the switch through a network cable; an access control terminal, which is arranged beside each carriage door, and which exchanges data with the switch on the same carriage through a network cable; an electric lock, which is arranged on each carriage door, and which is connected to the access control terminal on the same carriage through a locomotive cable; a call extension button, which is arranged under the frame of each carriage, and which is connected to the access control terminal on the same carriage through a locomotive cable.

[0006] Among them, the working vehicle is composed of two traction carriages and multiple intermediate working carriages located between the two traction carriages. The duty room is set on the intermediate working carriage, and the command room is set on the intermediate working carriage.

[0007] The number of intermediate working carriages can be configured according to actual needs, for example, it can be 2, 4, 6, 10, 12, 14, 15, 18, 20, etc.

[0008] Preferably, the switch adopts an industrial-grade managed Gigabit Ethernet switch with a wide temperature range and a wide voltage input range to meet vehicle-mounted shock and vibration requirements and the electromagnetic compatibility requirements of the vehicle, and can shield the corresponding faulty network port and quickly perform automatic recovery when a network failure occurs.

[0009] Preferably, the network cable is a CAT6A network cable, using the S / FTP process: aluminum foil wire pair shielding, tinned copper braided overall shielding, to meet the complex use environment requirements of the locomotive.

[0010] Preferably, the reconnection harness adopts CAT6A network cable and adopts S / FTP process: aluminum foil wire pair shielding and tinned copper braided overall shielding to meet the complex use environment requirements of the locomotive.

[0011] Preferably, the network cable uses an M12 industrial-grade connector at the switch end. The M12 connector is superior to the traditional RJ45 connector in terms of resistance to signal attenuation and resistance to vehicle impact vibration.

[0012] Preferably, the interface of the reconnection harness adopts a network connector assembly suitable for the railway industry. The network connector assembly suitable for the railway industry is superior to the traditional RJ45 connector in terms of resistance to signal attenuation and resistance to vehicle impact vibration.

[0013] Preferably, the reconnection harness is fixed to the vehicle frame via a reconnection socket.

[0014] Preferably, the electric lock is a power-off locking type lock. When the vehicle loses power, it automatically locks, reducing the workload of on-site construction personnel. Each electric lock is equipped with an emergency switch, and the door can be opened manually when an abnormality occurs in the electric control system, thereby improving the system's fault tolerance and the safety of the vehicle.

[0015] The access control system of the present invention is equipped with a switch (preferably an industrial-grade network-managed Gigabit Ethernet switch) in each carriage to support network nodes between carriages and data interaction between carriages; the access control host in the duty room and the command room is used to control the IP addresses of the access control terminals of the entire train; each access control terminal IP address corresponds to an electric lock, which is used to identify and control a specific door lock.

[0016] The second aspect of the present invention is to provide a door access control method applicable to the coupling of multiple working vehicles, and the door access control system described in the first aspect of the present invention is used to control the door access.

[0017] When the corresponding electric lock needs to be opened inside the car, the corresponding access control terminal ID is operated on the access control host, and the control information is transmitted to the switch of the corresponding car through the TCP / IP protocol. The switch then transmits the information to the corresponding access control terminal through the TCP / IP protocol. At this time, the output normally open point of the access control terminal is closed, and the control information is transmitted to the electric lock electrically connected to it, so as to open the electric lock and then realize the opening control of the door.

[0018] When the door is closed, the electric lock will feed back the lock status to the access control terminal electrically connected to it, and the access control terminal will feed back the lock status to the switch connected to its network through the TCP / IP protocol. The switch will then transmit the information to the access control host through the switches and reconnection harnesses between the carriages, so that the entire vehicle door status can be monitored on the access control host.

[0019] When it is necessary to request unlocking remotely outside the vehicle, call on the access control terminal or call extension button. The call status is transmitted to the switch of this car in the form of audio and / or video information through the TCP / IP protocol, and then transmitted to the access control host through the switch and reconnection harness between cars. When the access control host receives the call information, it can remotely authorize unlocking of specific door locks and remote video intercom on the access control host interface.

[0020] Preferably, the data terminal installed on the driver's console transmits the vehicle running speed information to the access control host through a switch connected to the network; when the entire train is in a stopped state and the speed is ≤10km / h, the access control host can control the door opening; when the speed is ≥10Km / h, the door lock switch cannot be operated on the access control host; if it is detected that a door lock is not in a locked state, the access control host will prompt.

[0021] Preferably, the access control host has an "emergency unlocking" function, and when emergency unlocking is performed, all vehicle doors are unlocked.

[0022] The third aspect of the present invention is to provide a vehicle having the access control system described in the first aspect of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and in combination with specific embodiments, so as to better understand the present invention. A working vehicle with 12 carriages connected together is used as an example for description.

[0028] The working vehicle consists of two traction carriages and 10 intermediate working carriages located between the two traction carriages. The duty room is located in the intermediate working carriage, and the command room is located in the intermediate working carriage.

[0029] like Figure 2 As shown, the access control system of this embodiment includes: a switch 10 arranged in the multimedia cabinet 1 of each carriage, an access control host arranged in the duty room and the command room, an access control terminal 2 arranged next to each carriage door, an electric lock 4 arranged on each carriage door, and a call extension button 8 arranged under the frame of each carriage.

[0030] The switch 10 is an industrial-grade managed Gigabit Ethernet switch, which is used to support the network communication nodes of the system. It has a wide temperature range and a wide voltage input range, meets the requirements of vehicle-mounted shock and vibration, and meets the requirements of electromagnetic compatibility of the whole vehicle. In addition, when a network failure occurs, the corresponding faulty network port can be shielded and automatically restored quickly.

[0031] The access control terminal 2 is connected to the switch 10 on the same carriage through a network cable 9 to send and receive network signals. The network cable 9 adopts CAT6A network cable and adopts S / FTP technology: aluminum foil wire pair shielding, tinned copper braided overall shielding, which meets the complex use environment requirements of the locomotive.

[0032] The access control terminal 2 and the electric lock 4 are electrically connected via a locomotive cable 3 , which is used to receive the unlocking signal from the access control terminal 2 and the lock status signal fed back by the electric lock 4 .

[0033] The traction carriage and the adjacent working carriage and the switches 10 on the two adjacent working carriages are connected through a reconnection harness 5 for cross-car information exchange. The reconnection harness 5 is fixed to the frame through a reconnection socket 6. The reconnection socket 6 and the switch 10 are connected by a network cable 9 for cross-car data exchange.

[0034] The call extension button 8 is electrically connected to the access control terminal 2 of the same carriage by a locomotive cable 7 for transmitting an unlocking request signal outside the vehicle.

[0035] The access control host is connected to the switch 10 via a network cable for data exchange, and is used for sending and receiving unlocking signals, remote visual intercom with the access control terminal 2, and remote sending of unlocking signals.

[0036] Among them, the reconnection harness 5 uses CAT6A network cable and adopts S / FTP process: aluminum foil wire pair shielding, tinned copper braided overall shielding, which meets the complex use environment requirements of locomotives. In addition, the network cable 9 uses M12 industrial-grade connectors at the switch 10 end, and the interface of the reconnection harness 5 uses network connector components suitable for the railway industry. M12 connectors and network connector components suitable for the railway industry are superior to traditional RJ45 connectors in terms of resistance to signal attenuation and vehicle impact vibration.

[0037] The electric lock 4 is a power-off locking type lock. When the vehicle loses power, it automatically locks, reducing the workload of on-site construction personnel. Each electric lock 4 is equipped with an emergency switch, and the door can be opened manually when the electronic control system is abnormal, thereby improving the fault tolerance of the system and the safety of the vehicle.

[0038] The access control system of this embodiment adopts a reconnected network control architecture, and a switch 10 (preferably an industrial-grade managed Gigabit Ethernet switch) is set in each carriage to support network nodes between carriages and data interaction between carriages; the access control host in the duty room and the command room is used to control the IP address of the access control terminal 2 of the entire train; each access control terminal IP address corresponds to an electric lock 4, which is used to identify and control a specific door lock.

[0039] When the corresponding electric lock 4 needs to be opened in the car, the corresponding access control terminal ID is operated on the access control host, and the control information is transmitted to the switch 10 of the corresponding car through the TCP / IP protocol. The switch 10 then transmits the information to the corresponding access control terminal 2 through the TCP / IP protocol. At this time, the output normally open point of the access control terminal 2 is closed, and the control information is transmitted to the electric lock 4 electrically connected thereto, so as to realize the opening of the electric lock 4 and then realize the opening control of the door. The electric lock 4 is set with a 9-second delay to facilitate people outside the car to board the door. When receiving the door opening signal, the access control terminal 2 outputs a voice prompt "The door lock is open, the status will remain for two minutes, please get on the car in time". The access control host interface can display the door lock status, using color distinction (for example: red-door lock open, green-door lock closed, gray-unlocking prohibited).

[0040] When the door needs to be closed, the door is pushed in through the door handle. When the electric lock 4 is aligned with the sensor plate installed on the door frame, the lock tongue pops out and enters the lock hole, thereby closing the door. The electric lock 4 has a lock status signal output, that is, the lock status corresponds to the switch status of the door. The electric lock 4 feeds back the lock status to the access control terminal 2 electrically connected to it. The access control terminal 2 feeds back the lock status to the switch 10 connected to the network through the TCP / IP protocol. The switch 10 then transmits the information to the access control host through the switch 10 between the carriages and the reconnection harness 5, so that the door status of the entire vehicle can be monitored on the access control host.

[0041] When it is necessary to remotely request unlocking outside the vehicle, call on the access control terminal 2 or the call extension button 8. The call status is transmitted to the switch 10 of the current car through the TCP / IP protocol in the form of audio and / or video information, and then transmitted to the access control host through the switch 10 between cars and the reconnection harness 5. When the access control host receives the call information, it can remotely authorize unlocking of the specific door lock, remote video intercom, etc. on the access control host interface. When the door lock is opened, the access control terminal 2 automatically plays the set voice (the door lock is open, the status will remain for two minutes, please get on the car in time). The access control system of the present invention adopts a network architecture mode, which well solves the access control problem of multi-car reconnection, and adopts a distributed architecture, and each car can add control points, which has good scalability.

[0042] The purpose of setting two sets of call terminals (call extension button 8 and access control terminal 2) outside the vehicle is to meet the need for unlocking calls when the vehicle is at a high platform or a low platform without the need for personnel to climb the ladder.

[0043] Combine the following Figure 3To illustrate how to solve the problem of access control calls and remote visual intercoms when people outside the vehicle are at high and low platforms without climbing the ladder: 200mm above the rail surface 12 is the low platform 13, and 1200mm above the rail surface 12 is the high platform 14. When a person is at the low platform 13, the access control host can be called through the call extension button 8 set on the lower plane of the frame. Figure 3 In B, 16 is the vertical viewing angle below, and 15 is the vertical viewing angle above. Figure 3 As shown in B, when a person is at a low platform, he or she can be within the 110° vertical viewing angle of the access control terminal 2 at a distance of 600mm from the vehicle body, realizing the functions of remote calling and remote video intercom. When a person is at a high platform 14, he or she can call the access control host through the access control terminal 2. Figure 3 In C, 17 is the left side of the horizontal viewing angle, and 18 is the right side of the horizontal viewing angle. Figure 3 As shown in Figure C, when a person is at a low platform, he or she is 600mm outside the vehicle body and is within the 110° horizontal viewing angle of the access control terminal 2, realizing the functions of remote call and remote video intercom. The person is arranged in a 1:1 ratio at two heights of 1700mm and 1800mm.

[0044] Moreover, the data terminal installed on the driver's console transmits information such as the vehicle running speed to the access control host through the switch 10 connected to the network; when the entire train is in a stopped state and the speed is ≤10km / h, the access control host can control the door opening; when the speed is ≥10Km / h, the door lock switch cannot be operated on the access control host; if it is detected that a door lock is not in a locked state, the access control host interface will display a door lock open alarm (red) and issue a prompt voice.

[0045] The access control host interface is equipped with an "Emergency Unlock" function. When using it, first press "Emergency Unlock", and then the main display interface pops up "Confirm whether to emergency unlock?" After confirmation, all doors are unlocked, and the control host issues a voice prompt.

[0046] The specific embodiments of the present invention are described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
