[0066] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a control circuit 100 of an emergency evacuation device, which is applied to a suspended vehicle. The emergency evacuation device 200 includes an opening and closing mechanism 210 and an evacuation ladder 220. The control circuit 100 includes: a train control and management system TCMS, a gateway valve 110, a zero-speed relay K1, and an arrival relay K2; a first end of the TCMS is electrically connected to a first end of a first normally closed contact (1-2 contact) of the zero-speed relay K1; a second end of the TCMS is electrically connected to a coil of the arrival relay K2; a third end of the TCMS is electrically connected to a power supply line; a first end of the gateway valve 110 is electrically connected to a power supply line; the gateway valve The second end of 110 is electrically connected to the coil of the zero-speed relay K1; the second end of the first normally closed contact (1-2 contact) of the zero-speed relay K1 is electrically connected to the first end of the normally closed contact (1-2 contact) of the arrival relay K2; the second end of the normally closed contact (1-2 contact) of the arrival relay K2 is electrically connected to the opening and closing mechanism 210; TCMS is used to control the vehicle to stop running when an emergency occurs, close the first normally closed contact (1-2 contact) of the zero-speed relay K1, and send an emergency evacuation command to the opening and closing mechanism 210, triggering the opening of the opening and closing mechanism 210 to allow the evacuation ladder 220 to descend to a suitable position.

[0067] In this application, TCMS stands for Train Control and Management System in English, which means train control and management system in Chinese. It is also called locomotive microcomputer control and monitoring system. Its main functions are to realize locomotive characteristic control, logic control, fault monitoring and self-diagnosis, and transmit information to the microcomputer display screen on the driver's console to intuitively reflect the real-time status of the locomotive to the driver.

[0068] like Figure 3 As shown, in this embodiment, the emergency evacuation device 200 can be arranged at the bottom frame of the vehicle body door of the suspended vehicle.

[0069] In this embodiment, the power supply line is electrically connected to a power supply, and the power supply may be provided in a vehicle.

[0070] In this embodiment, a speed sensor is provided in the gateway valve 110. When the vehicle running speed detected by the speed sensor is greater than zero, the gateway valve 110 sends a high-level signal to the coil of the zero-speed relay K1. When the vehicle running speed detected by the speed sensor is equal to zero, the gateway valve 110 does not send a high-level signal to the coil of the zero-speed relay K1. When an emergency occurs in the vehicle (such as a fire or a vehicle failure that cannot run), the TCMS will be triggered to control the vehicle to stop running. After the vehicle stops running, the gateway valve 110 does not send a high-level signal instruction to the coil of the zero-speed relay K1, causing the first normally closed contact (1-2 contact) of the zero-speed relay K1 to close. Since the vehicle is on a non-platform line, T CMS does not send a vehicle arrival signal instruction to the coil of the arrival relay K2, so that the normally closed contact is closed. TCMS sends an emergency evacuation instruction to the opening and closing mechanism 210. The opening and closing mechanism 210 may include a motor 211 and a telescopic door 212 that are interconnected. When the motor 211 receives the emergency evacuation instruction, the motor 211 drives the telescopic door 212 to open (that is, the telescopic door retracts to the inside of the emergency evacuation device 200), so that the unfixed part of the evacuation ladder 220 located above the telescopic door 212 is lowered to a suitable position. The top of the evacuation ladder 220 can be fixed on the inner wall of the emergency evacuation device 200. After the vehicle door is opened, the passengers in the suspended vehicle can reach a safe position by using the evacuation ladder 220.

[0071] Compared with the prior art, the present application provides a control circuit 100 for an emergency evacuation device, which is applied to a suspended vehicle. When an emergency occurs in the suspended vehicle, the TCMS in the control circuit 100 controls the vehicle to stop running, closes the first normally closed contact (1-2 contact) of the zero-speed relay K1, and sends an emergency evacuation command to the opening and closing mechanism 210 in the emergency evacuation device 200, triggering the opening and closing mechanism 210 to open, so that the evacuation ladder 220 in the emergency evacuation device 200 descends to a suitable position. After the vehicle door is opened, the passengers in the suspended vehicle can reach a safe position through the evacuation ladder 220, thereby effectively evacuating the passengers in the suspended vehicle, thereby effectively ensuring the safety of the passengers.

[0072] like Figure 1 As shown, as an implementation manner, in the embodiment of the present application, the control circuit 100 also includes: a first forced starting switch N1; a first end of the first forced starting switch N1 is electrically connected to the power supply line; a second end of the first forced starting switch N1 is electrically connected to a first end of a second normally closed contact (3-4 contact) of the zero-speed relay K1; a second end of the second normally closed contact (3-4 contact) of the zero-speed relay K1 is electrically connected to the opening and closing mechanism 210.

[0073] In this embodiment, when the TCMS fails and cannot send an emergency evacuation command to trigger the opening of the opening and closing mechanism 210, the driver can control the vehicle to stop running. After the vehicle stops running, the gateway valve 110 does not send a high-level signal command to the coil of the zero-speed relay K1, so that the second normally closed contact (3-4 contact) of the zero-speed relay K1 is closed. Specifically, when the gateway valve 110 does not send a high-level signal command to the coil of the zero-speed relay K1, the first normally closed contact (1-2 contact) and the second normally closed contact (3-4 contact) of the zero-speed relay K1 are both in a closed state. When the second normally closed contact (3-4 contact) of the zero-speed relay K1 is closed, the driver can manually or through a control device control the first forced start switch N 1 is closed, so that the motor 211 is energized. After the motor 211 is energized, it drives the telescopic door 212 to open, so that the unfixed part of the evacuation ladder 220 located above the telescopic door 212 is lowered to a suitable position. After the vehicle door is opened, the passengers in the suspended vehicle can descend to a safe position on the evacuation ladder 220. By providing the first forced start switch N1, when the TCMS fails and cannot send an emergency evacuation command to trigger the opening of the opening and closing mechanism 210, the first forced start switch N1 can be used to open the opening and closing mechanism 210, thereby avoiding the situation where the opening and closing mechanism 210 cannot be opened due to a TCMS failure, thereby preventing the emergency evacuation of passengers. In the event of an emergency in the vehicle, the safety of the passengers is further guaranteed.

[0074] like Figure 1As shown, as an implementation manner, in the embodiment of the present application, the control circuit 100 also includes: a second forced starting switch N2 and an isolation relay K3; the first end of the second forced starting switch N2 is electrically connected to the power supply line; the second end of the second forced starting switch N2 is electrically connected to the coil of the isolation relay K3; the first end of the normally open contact (1-2 contact) of the isolation relay K3 is electrically connected to the second end of the first forced starting switch N1; the second end of the normally open contact (1-2 contact) of the isolation relay K3 is electrically connected to the opening and closing mechanism 210.

[0075] In this embodiment, when both the TCMS and the zero-speed relay K1 fail and cannot trigger the opening of the opening and closing mechanism 210, the driver can control the vehicle to stop running. The driver can manually or through a control device control the first forced start switch N1 and the second forced start switch N2 to close, so that the motor 211 is energized. After the motor 211 is energized, it drives the telescopic door 212 to open, so that the unfixed part of the evacuation ladder 220 located above the telescopic door 212 is lowered to a suitable position. After the vehicle door is opened, the passengers in the suspended vehicle can descend to a safe position on the evacuation ladder 220. By providing the first forced start switch N1 and the second forced start switch N2, when both the TCMS and the zero-speed relay K1 fail and cannot trigger the opening of the opening and closing mechanism 210, the opening and closing mechanism 210 can be opened by the first forced start switch N1 and the second forced start switch N2. This avoids the situation where the opening and closing mechanism 210 cannot be opened due to the failure of the TCMS and the zero-speed relay K1, thereby preventing the emergency evacuation of passengers. In the event of an emergency in the vehicle, the safety of passengers is further ensured.

[0076] like Figure 1 As shown, as an implementation manner, in the embodiment of the present application, the control circuit 100 further includes: a first diode P1, a second diode P2, a third diode P3 and a fourth diode P4; the anode of the first diode P1 is electrically connected to the second end of the gateway valve 110; the cathode of the first diode P1 is electrically connected to the coil of the zero-speed relay K1; the anode of the second diode P2 is electrically connected to the second end of the TCMS; the cathode of the second diode P2 is electrically connected to the coil of the arrival relay K2; the anode of the third diode P3 is electrically connected to the second end of the second forced start switch N2; the cathode of the third diode P3 is electrically connected to the coil of the isolation relay K3; the anode of the fourth diode P4 is electrically connected to the second end of the first forced start switch N1; the cathode of the fourth diode P4 is electrically connected to the first end of the second normally closed contact (3-4 contact) of the zero-speed relay K1 and the first end of the normally closed contact (1-2 contact) of the isolation relay K3.

[0077] In this embodiment, the function of the first diode P1, the second diode P2, the third diode P3 and the fourth diode P4 is to prevent the signal from flowing back. By setting the first diode P1, the second diode P2, the third diode P3 and the fourth diode P4, the signal at the negative end of the diode can be effectively prevented from flowing to the positive end.

[0078] like Figure 1 、 Figure 2 and Figure 4 As shown, the present application also provides an emergency evacuation system, which is applied to a suspended vehicle. The emergency evacuation system includes: the control circuit 100 of the emergency evacuation device mentioned above, and the emergency evacuation device 200; the emergency evacuation device 200 includes a main body 230, an opening and closing mechanism 210 and an evacuation ladder 220; the bottom of the main body 230 is provided with an exit 240; the top of the evacuation ladder 220 is fixedly connected to the inner wall of the main body 230; the opening and closing mechanism 210 includes a motor 211 and a telescopic door 212, the motor 211 and the telescopic door 212 are connected, and the motor 211 is connected to the arrival relay K in the control circuit 100. 2, the second end of the second normally closed contact (1-2 contact) of the zero-speed relay K1 in the control circuit 100, and the second end of the normally open contact (1-2 contact) of the isolation relay K3 in the control circuit 100 are electrically connected; when the motor 211 does not receive an emergency evacuation command and loses power, the telescopic door 212 is closed, and the telescopic door 212 is located between the evacuation soft ladder 220 and the exit 240. When the motor 211 receives an emergency evacuation command or is powered on, the motor 211 drives the telescopic door 212 to open, so that the evacuation soft ladder 220 descends to a suitable position.

The top of the evacuation soft ladder 220 can be fixedly connected to the inner wall of the main body 230 by a fixing member 250; after the telescopic door 212 of the opening and closing mechanism 210 is opened, the unfixed part of the evacuation soft ladder 220 can rely on its own weight in the vertical direction to directly pass through the exit 240 and descend to a suitable position without external intervention.

[0080] In this embodiment, an inspection port may be provided at the upper end of the emergency evacuation device 200.

In this embodiment, the inspection port is not shown in the accompanying drawings.

[0081] like Figure 5 As shown, as an embodiment, in the embodiment of the present application, the evacuation ladder 220 includes multiple climbing aids 221, a safety fixing rope 222, and a retractable rope 223. The safety fixing rope 222 is fixedly connected to both sides of the multiple climbing aids 221, and the top of the safety fixing rope 222 is fixedly connected to the inner wall of the main body 230.
