[0002] With the development of the national economy and social production, rail transit is playing an increasingly important role in urban construction, gaining popularity due to its large passenger capacity and high speed. To ensure passenger safety, safety systems applied to platform doors play a vital role. These safety systems include train emergency stop switches and local control boxes.

[0003] Currently, one or more train emergency stop switches are installed on the wall, and the local control box is installed on the platform door. When an accident occurs, it is necessary to disconnect the train emergency stop switch first, and then operate the local control box to control the platform door of the rail transit station to resolve the accident.

Therefore, most staff members directly operate the local control box to control the platform door in an emergency. There is a high possibility of misoperation when directly operating the local control box without disconnecting the emergency stop switch, and the train may be in normal operation during operation, so it is very dangerous.

[0033] As previously mentioned, at current rail transit stations, such as subway stations, one or more emergency stop switches are mounted on the wall, and a local control box is installed on the platform door. In the event of an emergency, the normal procedure is to first disconnect the emergency stop switch and then operate the local control box to control the platform door. However, because the emergency stop switch is located on the wall, it is far from some platform doors. In an emergency, staff members are unable to disconnect the emergency stop switch in time. Therefore, most staff members choose to directly operate the local control box to control the platform door in an emergency. However, directly operating the local control box without disconnecting the emergency stop switch is more likely to cause an error, which could result in the platform door opening while the train is in normal operation, thus being highly dangerous.

[0034] In an embodiment of the present application, the safety system includes a safety circuit, multiple emergency stop switches and multiple local control boxes. Each platform door is provided with an emergency stop switch and a local control box. When an emergency occurs, the staff can disconnect the safety circuit through the emergency stop switch on the platform door to stop the train, and then control the platform door through the local control box. This avoids the danger caused by the train emergency stop switch being too far from the platform door and the emergency stop switch not being disconnected in time in an emergency. Therefore, the danger of the staff operating the platform door can be reduced, and since the emergency stop switch is installed on the platform door, the efficiency of the staff in handling emergencies is improved.

[0035] The safety system, isolation door and safety door provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of a security system provided by an embodiment of the present application. Figure 1 As shown, the safety system 100 provided in an embodiment of the present application is applied to a platform door 400 of a rail transit station. The safety system 100 includes a safety circuit 101, at least one emergency stop switch 102, and at least one local control box 103. The safety circuit 101 is connected to the train control system 200, and the at least one emergency stop switch 102 is connected in series within the safety circuit 101. The at least one local control box 103 is connected to the platform door control system 300. The at least one emergency stop switch 102 and the at least one local control box 103 are disposed on the platform door 400, with each platform door 400 being provided with at most one emergency stop switch 102 and one local control box 103. The emergency stop switch 102 can control the on / off state of the safety circuit 101, so that when the safety circuit 101 is disconnected, it sends a train stop signal to the train control system 200. The local control box 103 can control the corresponding platform door 400.

[0037] The safety system 100 includes a safety circuit 101 connected to a train control system 200. When the safety circuit 101 is disconnected, the train control system 200 sends a stop signal to the train, causing the train to stop. For example, the safety circuit 101 can be connected between a power source and the train control system 200. When the safety circuit 101 is disconnected, the train control system 200 loses power and is unable to send start commands to the train, causing the train to stop. Alternatively, the safety circuit 101 can be connected to a signal generator in the control system. When the safety circuit 101 is disconnected, the signal generator inputs a low level, sending a stop signal to the train, causing the train to stop.

[0038] The safety system 100 provided in the embodiment of the present application includes a plurality of emergency stop switches 102 and a local control box 103. Each platform door 400 of a rail train station is provided with an emergency stop switch 102 and a local control box 103. Each emergency stop switch 102 is connected in series to a safety circuit 101. When any one or more emergency stop switches 102 are disconnected, the safety circuit 101 is disconnected, and the train receives a stop signal and stops. The local control box 103 is connected to the control system of the platform door 400 and can control the platform door 400. For example, the local control box 103 is a multi-position switch that can achieve different effects when in different positions. For example, when in the first position, the door can be manually opened, and when in the second position, the door can be manually closed, and so on.

[0039] Optionally, the emergency stop switch 102 can be an automatic reset switch or a manual reset switch. When an emergency occurs, press the emergency stop switch 102 on the platform door 400 to disconnect the safety circuit 101. When the situation is resolved, reset the emergency stop switch 102 to put the safety circuit 101 in an on state so that the train can operate normally.

[0040] In an embodiment of the present application, the safety system 100 includes a safety circuit 101, multiple emergency stop switches 102 and multiple local control boxes 103. Each platform door 400 is provided with an emergency stop switch 102 and a local control box 103. When an emergency occurs, the staff can disconnect the safety circuit 101 through the emergency stop switch 102 on the platform door 400 to stop the train, and then control the platform door 400 through the local control box 103. This avoids the danger caused by the train emergency stop switch 102 being too far from the platform door 400 and the emergency stop switch 102 not being able to be disconnected in time in an emergency. Therefore, the danger of the staff operating the platform door 400 can be reduced, and since the emergency stop switch 102 is installed on the platform door 400, the efficiency of the staff in handling emergencies is improved.

[0041] Figure 2is a schematic diagram of another security system provided in an embodiment of the present application, such as Figure 2 As shown, the local control box 103 includes a first safety switch K1. The platform door status switch T of the platform door 400 where the local control box 103 is located is connected in series within the safety circuit 101. The platform door status switch T is open or closed based on the open or closed state of the platform door 400. The first safety switch K1 is connected in parallel with the platform door status switch T. When closed, the first safety switch K1 can short-circuit the platform door status switch T.

[0042] Each platform door 400 has a corresponding platform door status switch T on the safety circuit 101. When the platform door 400 is closed, the platform door status switch T is closed. At this time, with all emergency stop switches 102 closed, the safety circuit 101 is connected, and the train can run. When the platform door 400 is opened, the platform door status switch T is opened, and the safety circuit 101 is disconnected, and the train stops.

[0043] Each local control box 103 includes a first safety switch K1. The first end of the first safety switch K1 is connected to the first end of the platform door status switch T, and the second end of the first safety switch K1 is connected to the second end of the platform door status switch T. When the first safety switch K1 is closed, the platform door status switch T is short-circuited. At this time, regardless of whether the platform door status switch T is in the closed or open state, the safety circuit 101 is in the on state, that is, the train can run regardless of whether the platform door 400 is open or closed.

[0044] In an embodiment of the present application, the local control box 103 on the platform door 400 includes a first safety switch K1. The first safety switch K1 can short-circuit the corresponding platform door status switch T on the safety circuit 101, thereby avoiding the situation where the train cannot run due to the temporary inability to close the platform door 400 or the failure of the platform door status switch T, thereby ensuring the normal operation of the train.

[0045] Figure 3 This is a schematic diagram of another security system provided by an embodiment of the present application. Figure 3 As shown, the safety system 100 further includes at least one second safety switch K2. A platform door status switch T of the platform door 400 is connected in series in the safety circuit 101. The platform door status switch T is in an open or closed state based on the open or closed state of the platform door 400. The second safety switch K2 is connected in parallel with the platform door status switch T, and different second safety switches K2 are connected in parallel with different platform door status switches T. The second safety switch K2 can short-circuit the platform door status switch T when closed.

[0046] The safety system 100 also includes multiple second safety switches K2, which are arranged on the platform door 400. Different platform doors 400 are provided with different second safety switches K2. Each second safety switch K2 corresponds one-to-one to the platform door status switch T of the platform door 400. The first end of the second safety switch K2 is connected to the first end of the platform door status switch T, and the second end of the second safety switch K2 is connected to the second end of the platform door status switch T. When the second safety switch K2 is closed, the platform door status switch T is short-circuited. At this time, regardless of whether the platform door status switch T is in the closed or open state, the safety circuit 101 is in the on state, that is, the train can run regardless of whether the platform door 400 is open or closed.

[0047] It should be noted that the second safety switch K2 and the local control box 103 are set in different areas. Operating the local control box 103 will not close or open the second safety switch K2. Therefore, when operating the local control box 103, the possibility of short-circuiting the platform door status switch T due to misoperation can be avoided.

[0048] In the embodiment of the present application, the safety system 100 includes multiple second safety switches K2. When closed, the second safety switches K2 can short-circuit the platform door status switch T of the corresponding platform door 400 in the safety circuit 101. This prevents the train from being unable to operate due to the temporary inability to close the platform door 400 or a malfunction of the platform door status switch T, thereby ensuring the train's operation. Furthermore, because the second safety switches K2 are located in the safety system 100 rather than in the local control box 103, operating the local control box 103 can prevent the platform door status switch T from being short-circuited due to accidental operation, thereby reducing the risk of personnel operating the platform door 400.

[0049] Figure 4 Schematic diagram of a safety system including two safety branches provided in an embodiment of the present application. Figure 4 As shown, the safety circuit 101 includes a first safety branch 1011 and a second safety branch 1012, and the emergency stop switch 102 includes a first emergency stop sub-switch 1021 and a second emergency stop sub-switch 1022. Each first emergency stop sub-switches 1021 is connected in series in the first safety branch 1011, and each second emergency stop sub-switches 1022 is connected in series in the second safety branch 1012. The first emergency stop sub-switches 1021 and the second emergency stop sub-switches 1022 in the same emergency stop switch 102 operate synchronously. The first emergency stop sub-switch 1021 can control the on / off of the first safety branch 1011, and the second emergency stop sub-switch 1022 can control the on / off of the second safety branch 1012.

[0050] Safety circuit 101 includes a first safety branch 1011 and a second safety branch 1012. The first safety branch 1011 and the second safety branch 1012 are connected to the train control system 200 to form a double-break safety circuit. For example, the first safety branch 1011 is connected to the live line of the train control system 200 power supply, and the second safety branch 1012 is connected to the neutral line of the train control system 200 power supply. Alternatively, the two branches may be connected in series. When the first safety branch 1011 and / or the second safety branch 1012 are disconnected, the train control system 200 sends a stop signal to the train, causing the train to stop.

[0051] Each emergency stop switch 102 includes a first emergency stop sub-switch 1021 and a second emergency stop sub-switch 1022. When the emergency stop switch 102 is controlled, the first emergency stop sub-switch 1021 and the second emergency stop sub-switch 1022 included in the emergency stop switch 102 are synchronously closed or opened. That is, when the emergency stop switch 102 is opened, the first emergency stop sub-switch 1021 and the second emergency stop sub-switch 1022 included in the emergency stop switch 102 are also opened. Each first emergency stop sub-switch 1021 is connected in series to the first safety branch 1011 of the safety circuit 101, and each second emergency stop sub-switch 1022 is connected in series to the second safety branch 1012. When at least one first emergency stop sub-switch 1021 and / or the second emergency stop sub-switch 1022 is opened, the safety circuit 101 is disconnected, and the train control system 200 sends a stop signal to the train, causing the train to stop.

[0052] In the embodiment of the present application, the safety circuit 101 includes a first safety branch 1011 and a second safety branch 1012, and the emergency stop switch 102 includes a first emergency stop sub-switch 1021 and a second emergency stop sub-switch 1022. The first emergency stop sub-switch 1021 is connected in series to the first safety branch 1011, and the second emergency stop sub-switch 1022 is connected in series to the second safety branch 1012. When the first safety branch 1011 and / or the second safety branch 1012 are disconnected, the safety circuit 101 is disconnected and the train stops. The provision of a double-break circuit reduces the possibility of the safety circuit 101 not being properly disconnected due to mechanical or electronic failure, resulting in normal operation of the train with the platform door 400 open. This reduces the risk of staff operating the platform door 400.

[0053] Figure 5 is a schematic diagram of another safety system including two safety branches provided in an embodiment of the present application, such as Figure 5As shown, the local control box 103 includes a third safety switch K3 and a fourth safety switch K4. The platform door status switch T of the platform door 400 where the local control box 103 is located includes a first status switch T1 and a second status switch T2. The first status switch T1 is connected in series in the first safety branch 1011, and the second status switch T2 is connected in series in the second safety branch 1012. The first status switch T1 and the second status switch T2 in the same platform door status switch T operate synchronously. Depending on whether the platform door 400 is open or closed, the third safety switch K3 is connected in parallel with the first status switch T1, and the fourth safety switch K4 is connected in parallel with the second status switch T2. When closed, the third safety switch K3 can short-circuit the first status switch T1, and the fourth safety switch K4 can short-circuit the second status switch T2.

[0054] The status switches of the platform door 400 include a first status switch T1 and a second status switch T2. The first status switch T1 and the second status switch T2 operate synchronously. When the platform door 400 is closed, the first status switch T1 and the second status switch T2 are closed synchronously. When all platform doors 400 are closed, the first safety branch 1011 and the second safety branch 1012 are both turned on, the safety circuit 101 is turned on, and the train control system 200 sends a start signal to the train, and the train starts.

[0055] When at least one platform door 400 is not closed, the first state switch T1 and / or the second state switch T2 in the platform door state switch T corresponding to the platform door 400 are disconnected. At this time, the first safety branch 1011 and / or the second safety branch 1012 are disconnected, the safety circuit 101 is broken, and the train control system 200 sends a stop signal to the train, and the train stops.

[0056] Optionally, the first status switch T1 may correspond to whether the platform door 400 is closed. When the platform door 400 is closed, the first status switch T1 is closed; when the platform door 400 is open, the first status switch T1 is open. The second status switch T2 may correspond to whether the platform door 400 is locked. When the platform door 400 is closed and locked, the second status switch T2 is closed. When the platform door 400 is not closed or is closed but not locked, the second status switch T2 is open. The specific function corresponding to the platform door status switch T is not limited in this embodiment of the application.

[0057] Each local control box 103 includes a third safety switch K3 and a fourth safety switch K4. The first end of the third safety switch K3 is connected to the first end of the first state switch T1 of the platform door 400 where the local control box 103 is located, and the second end of the third safety switch K3 is connected to the second end of the first state switch T1 of the platform door 400 where the local control box 103 is located. The first end of the fourth safety switch K4 is connected to the first end of the second state switch T2 of the platform door 400 where the local control box 103 is located, and the second end of the fourth safety switch K4 is connected to the second end of the second state switch T2 of the platform door 400 where the local control box 103 is located.

[0058] When the third safety switch K3 is closed, the first state switch T1 is short-circuited. At this time, regardless of whether the first state switch T1 is closed or not, the first safety branch 1011 is in the on state. When the fourth safety switch K4 is closed, the second state switch T2 is short-circuited. At this time, regardless of whether the second state switch T2 is closed or not, the second safety branch 1012 is in the on state.

[0059] Optionally, the third safety switch K3 and the fourth safety switch K4 can be operated synchronously, i.e., a single button can be used to simultaneously control the on and off of the third safety switch K3 and the fourth safety switch K4. This can simultaneously short-circuit the first state switch T1 and the second state switch T2, reducing the complexity of manual operation and disconnecting the platform door 400 from the safety circuit 101.

[0060] In an embodiment of the present application, the local control box 103 includes a third safety switch K3 and a fourth safety switch K4. The third safety switch K3 is connected in parallel with the first state switch T1 on the first safety branch 1011, and the fourth safety switch K4 is connected in parallel with the second state switch T2 on the second safety branch 1012. The first state switch T1 and the second state switch T2 on the safety circuit 101 can be short-circuited through the third safety switch K3 and the fourth safety switch K4, thereby avoiding the situation where the train cannot run due to the temporary inability to close the platform door 400 or the failure of the platform door state switch T, thereby ensuring the operation of the train.

[0061] Figure 6 This is a schematic diagram of another safety system including two safety branches provided in an embodiment of the present application. Figure 6As shown, the safety system 100 further includes: at least one fifth safety switch K5 and at least one sixth safety switch K6. The platform door state switch T of the platform door 400 includes a third state switch T3 and a fourth state switch T4. The third state switch T3 is connected in series in the first safety branch 1011, and the fourth state switch T4 is connected in series in the second safety branch 1012. The third state switch T3 and the fourth state switch T4 in the same platform door state switch T operate synchronously. Based on the open or closed state of the platform door 400, the fifth safety switch K5 is connected in parallel with the third state switch T3, and different fifth safety switches K5 are connected in parallel with different third state switches T3. The sixth safety switch K6 is connected in parallel with the fourth state switch T4, and different sixth safety switches K6 are connected in parallel with different fourth state switches T4. When closed, the fifth safety switch K5 can short-circuit the third state switch T3, and the sixth safety switch K6 can short-circuit the fourth state switch T4.

[0062] The third state switch T3 and the fourth state switch T4 are similar to the first state switch T1 and the second state switch T2 in the above embodiment, and are not described in detail here.

[0063] The safety system 100 includes multiple fifth safety switches K5 and sixth safety switches K6. Each platform door 400 is equipped with one fifth safety switch K5 and one sixth safety switch K6. The first end of the fifth safety switch K5 is connected to the first end of the third state switch T3 in the platform door state switch T, and the second end of the fifth safety switch K5 is connected to the second end of the third state switch T3. The first end of the sixth safety switch K6 is connected to the first end of the fourth state switch T4 in the platform door state switch T, and the second end of the sixth safety switch K6 is connected to the second end of the fourth state switch T4. When the fifth safety switch K5 is closed, the third state switch T3 is short-circuited, thus the first safety branch 1011 remains conductive regardless of whether the third state switch T3 is closed. When the sixth safety switch K6 is closed, the fourth state switch T4 is short-circuited, thus the second safety branch 1012 remains conductive regardless of whether the fourth state switch T4 is closed.

[0064] Optionally, the fifth safety switch K5 and the sixth safety switch K6 can be operated synchronously, i.e., a single button can be used to simultaneously control the on and off of the fifth safety switch K5 and the sixth safety switch K6. This can simultaneously short-circuit the third state switch T3 and the fourth state switch T4, reducing the complexity of manual operation and disconnecting the platform door 400 from the safety circuit 101.

[0065] In the embodiment of the present application, the safety system 100 includes a plurality of fifth safety switches K5 and sixth safety switches K6. Each fifth safety switch K5 is connected in parallel with the third state switch T3 of the platform door 400 on the first safety branch 1011, and each sixth safety switch K6 is connected in parallel with the platform door state switch T of the platform door 400 on the second safety branch 1012. The fifth and sixth safety switches K5 and K6 can short-circuit the third state switch T3 and the fourth state switch T4 on the safety circuit 101, thereby preventing the train from being unable to operate due to a temporary inability to close the platform door 400 or a malfunction of the platform door state switch T, thereby ensuring the operation of the train. Furthermore, because the fifth and sixth safety switches K5 and K6 are disposed in the safety system 100 rather than in the local control box 103, the possibility of accidentally short-circuiting the platform door state switch T when operating the local control box 103 can be avoided, thereby reducing the risk of manual operation of the platform door 400.

[0066] Figure 7 Schematic diagram of a safety system including a reset module provided in an embodiment of the present application. Figure 7 As shown, the safety system 100 includes at least one reset module 104 . There is a one-to-one correspondence between the at least one reset module 104 and the emergency stop switch 102 . The reset module 104 is used to close the corresponding emergency stop switch 102 .

[0067] The safety system 100 includes multiple reset modules 104, each reset module 104 corresponds to the emergency stop switch 102, and different reset modules 104 correspond to different emergency stop switches 102. When the emergency stop switch 102 is manually closed, the safety circuit 101 will not be connected. It is necessary to operate the reset module 104 after closing the emergency stop switch 102 before the safety circuit 101 will be connected. That is, after manually closing the emergency stop switch 102, it is necessary to operate the corresponding reset module 104 to connect the safety circuit 101.

[0068] The reset module 104 in the embodiment of the present application can be a reset switch, a programmable single chip microcomputer, a safety relay, etc.

[0069] In an embodiment of the present application, the safety system 100 includes multiple reset modules 104, and the reset modules 104 correspond one-to-one to the emergency stop switches 102. When the emergency stop switch 102 is manually closed, the reset module 104 needs to be operated synchronously to turn on the safety circuit 101, thereby avoiding the situation where the emergency stop switch 102 is closed due to accidental operation when the platform door 400 is manually operated, thereby further improving the safety of the safety system 100.

[0070] In a possible implementation, the reset module 104 includes a reset switch and a relay. When the reset switch is closed, the relay is driven to control the emergency stop switch 102 to be closed.

[0071] In an embodiment of the present application, the reset module 104 includes a reset switch and a relay. After the emergency stop switch 102 is manually closed, the reset switch needs to be closed. At this time, the relay is closed and the safety circuit 101 is turned on, avoiding the situation where the emergency stop switch 102 is closed due to accidental operation when the staff operates the platform door 400, further improving the safety of the safety system 100, and the reset process is simple to operate, which improves the efficiency of resetting the emergency stop switch 102.

[0072] The present application also provides a rail transit platform isolation door, including any safety system 100 in the above embodiments.

[0073] Optionally, the emergency stop switch 102 can be installed on the doorpost of the isolation door, the safety switches (including the above-mentioned first safety switch K1 to fifth safety switch K5) can be installed on the left half of the operating box above the isolation door, and the local control box 103 can be installed on the right half of the operating box above the isolation door. The specific installation position is not limited in this application.

[0074] In an embodiment of the present application, the emergency stop switch 102 is installed on the doorpost of the isolation door, which makes it convenient for the staff to cut off the safety circuit 101 in time. The local control box 103 and the safety switches (including the above-mentioned first safety switch K1 to the fifth safety switch K5) are installed separately, thereby avoiding the occurrence of accidental operation of the safety switches (including the above-mentioned first safety switch K1 to the fifth safety switch K5) when operating the local control box 103, thereby further improving safety.
