Furthermore, if a passenger faints, experiences convulsions, or suffers other sudden illnesses on the platform, or a special person requires emergency assistance, the train will need to brake or remain stationary, and no further trains will be allowed to enter. Currently, subway platforms are equipped with emergency intercoms and emergency stop buttons to allow staff to promptly understand and address the situation.

[0003] Currently, the emergency intercom and emergency stop button (ESB) systems used on subway platforms are located separately at different locations on the platform level to handle different functions. The emergency intercom system is mainly used for emergency conversations between passengers and train control room staff. It is generally installed on both ends of the platform (two in total) to meet the intercom needs of both normal and disabled people. The emergency stop button is installed on a column or wall opposite the platform door, facing away from the passengers. Existing ESBs are mostly made of metal and are cylindrical or cube-shaped (determined by the characteristics and customs of the local city subway). They generally include an emergency stop button and lead seal on the protruding cylindrical body, and a rounded rectangular sign placed behind the body in contact with the wall.

[0004] In the existing technology, the subway emergency intercom and emergency stop terminal are set separately, which is inconvenient in actual use and operation. In addition, there is a lack of video conversation function, and the staff on duty in the train control room cannot see the on-site situation in time, which affects their judgment. In addition, the emergency stop button is not prominent enough, the installation position is not facing the passengers, and there is no sound or light alarm.

When any button is triggered, their respective connected modules are instantly connected and linked.

[0024] It should be noted here that the power panel and FXG distribution cabinet are located in the signal equipment room. The power panel and battery provide uninterrupted power supply for the integrated platform emergency stop device and its circuit. The cables of the emergency stop device are classified and connected to each cabinet equipment through the distribution cabinet, which is convenient for operators to inspect and maintain. Among them, the power panel, FXG distribution cabinet and IBP disk are mature existing technical equipment, and this solution does not make any improvements. This embodiment is only used to illustrate the principle.

[0025] In this embodiment, the housing 1 is a cubic structure measuring 600mm long, 250mm wide, and 40mm thick, made of ABS (acrylonitrile butadiene styrene). The device is bolted to the platform door post, and the control and power cables are routed through cable holes and run through the platform door cable duct back to the signal equipment room.

Pressing any of the emergency intercom buttons 2 automatically connects the camera 3, speaker 5, and microphone 6, allowing passengers to communicate with subway staff. The staff can also view the passengers and surroundings on the train control room workstation display.

[0026] Among them, the emergency stop button 4 is a special button for the subway signal system, with a lead seal on the surface, and is only used in emergency situations; the words "Press the red button to stop, only use when safety is endangered" are set below the emergency stop button 4 to remind users more clearly; the emergency stop button 4 is connected to the camera 3, the speaker 5 and the alarm light strip 7, and the emergency stop button 4 is connected to the signal system cabinet through a control cable. When an emergency occurs, open the lead seal, press the button, the speaker 5 will emit a preset alarm sound, the alarm light strip 7 will flash red, and the camera 3 will be turned on at the same time. The on-duty personnel can observe the platform situation through the train control room workstation display.

[0027] The emergency stop working principle of this embodiment is as follows:

[0028] After pressing the emergency stop button, the first normally open contact 11 / 12 and the second normally open contact 21 / 22 of relay SESB are closed, and the DC power flows through the first normally open contact 11 / 12 of relay SESB, the 1 / 2 node of XESB.LED1 coil, the emergency stop button alarm light strip flashes red, the first normally open contact 11 / 13 of relay ESB0101, the module connector of the IO subrack, and then the second normally open contact 21 / 23 of relay VI0101. The speaker VI0101 plays the alarm, the first normally open contact 11 / 13 of relay LS0101 is closed, the camera LS0101 is turned on, the platform image is projected on the duty room display, and finally returns to the first normally open contact 21 / 22 of relay SESB to form a loop, thereby controlling the train to remain stationary or emergency brake.

[0029] The ESB-0101 and ESB-0102 circuit loops of the two emergency stop buttons on the same side platform are connected in parallel and independently, and the relay nodes through which the DC power flows are basically the same. Pressing any button on the same side platform can realize the train emergency braking function.

[0030] In case of emergency, press the emergency stop button on the IBP panel, the first normally open contact 11 / 12 and the second normally open contact 21 / 22 of relay SESB-0101 will close, and the first normally open contact 11 / 12 and the second normally open contact 21 / 22 of relay SESB-0102 will close, which can also realize loop control to keep the train stationary or emergency braking.

[0031] The working principle of the emergency intercom in this embodiment is as follows:

[0032] When the emergency intercom button is pressed, the intercom circuit is connected: DC power flows sequentially through relay VIO101, closing the first normally open contacts 11 / 13. This closes speaker VI0101 and microphone SY0101, allowing passengers to communicate directly with the attendant. The video circuit is also connected: DC power flows sequentially through relay LS0101, closing the first normally open contacts 11 / 13. This connects camera LS0101, then through the module connector on the IO subrack, to relay EI0101, connecting to the first normally open contacts 11 / 13, DJ.LED1 coil 1 / 2 nodes, and the emergency intercom light strip flashes blue. The emergency intercom button uses two control circuits to enable passengers to communicate directly with the attendant. The attendant can also see the passengers and the surrounding environment through the camera.

[0033] The circuits of the two emergency intercom buttons VI0101 and VI0102 on the same side platform are independent of each other, and the DC power flows through different relay nodes. Pressing any button on the same side platform can only connect the emergency intercom function of this device.

[0034] This embodiment adds an integrated emergency stop device to the platform level of urban subway stations. When emergencies such as train trapping people or objects, or platform / train fire occur, the following procedures are performed according to the urgency of the situation: when the train does not need to remain stationary, passengers who encounter difficulties can press the emergency intercom button to talk to the subway duty personnel in the train control room and describe the current situation. At the same time, the duty personnel can see the current situation of the passengers through the workstation display and camera 3; when an emergency occurs and the train needs emergency braking or stationary, the passenger or subway staff presses the emergency stop button and the platform train implements emergency braking or remains stationary, and subsequent trains are prohibited from entering the platform of this station. At the same time, the speaker 5 of the emergency stop device sounds an alarm, the alarm light strip 7 flashes red, and the camera 3 is turned on. The train control room staff confirms the situation on the scene immediately through the workstation display and evacuates the crowd through the communication system broadcast, thereby reducing casualties and property losses.
