Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and more particularly to a portable visual intelligent braking and response device for subway vehicles and its usage method. Background Technology

[0002] After the static commissioning of the subway train is completed, a motor steering test is conducted before it goes into operation. This test requires the driver to drive the train at low speed inside the factory. During the test, the safe driving distance inside the factory is limited. If the driver operates improperly, it can easily cause collisions with the trains in front or behind, or scrape against the warehouse doors, personnel, and other safety accidents. Therefore, it is necessary to operate the subway train under special working conditions to effectively ensure the safety of train operation even if the driver makes a mistake. Thus, an anti-overshooting system was developed.

[0003] The existing anti-overshooting system places the anti-overshooting device in the driver's cab, connects the device to the signal system in the driver's cab, uses GPS positioning to control the vehicle's position on the test track, and sets the relationship between safe distance and vehicle speed, thereby controlling the vehicle to apply braking force when it reaches the GPS-set area.

[0004] However, since the anti-overshooting system relies on GPS to set the vehicle's operating position and apply braking force, in the static testing workshop, the distance between each train is only about 5 meters, making it impossible to use GPS for precise positioning. Therefore, the anti-overshooting system cannot be used for active braking, and the safety of vehicle operation cannot be guaranteed. Summary of the Invention

[0005] To address the aforementioned technical problems of existing anti-overtaking systems' inability to utilize GPS for precise positioning and guarantee vehicle operational safety, this invention provides a portable, visual, intelligent braking and response device for subway vehicles, along with its usage method. This invention primarily utilizes optocoupler technology combined with wireless radio frequency transmission. A photoelectric probe and a mirror reflector sense and control a multi-functional relay to trigger a wireless radio frequency transmitter, outputting a braking signal to the vehicle. When this signaling device is applied during train commissioning and operation, it ensures vehicle operational safety.

[0006] The technical means employed in this invention are as follows:

[0007] A portable, visual, intelligent braking and response device for subway vehicles includes:

[0008] The ground box sends the first braking signal to the on-board box when the subway car passes the safety distance position. The ground box is fixed to the lower surface of the subway car.

[0016] Furthermore, the track limiting device includes a limit switch and a first wireless radio frequency transmitting module. The limit switch is fixed to the inside of the track by a track-specific bracket. The track limiting device is connected to the track limiting device on the other side by a cable to form a loop. At the same time, pressing the contacts of the left and right limit switches controls the first wireless radio frequency transmitting module to send a second braking signal to the first wireless radio frequency receiving module.

[0017] Furthermore, the ground box is equipped with a rechargeable battery and a power display module, and the power input signal output unit supplies power to the vehicle box.

[0018] Furthermore, the vehicle-mounted box is equipped with a buzzer, which sounds an alarm when the vehicle-mounted box receives the first braking signal, the second braking signal, and the third braking signal.

[0019] Furthermore, when a subway vehicle passes the mirror reflector, the infrared rays emitted by the infrared emitting device are reflected by the mirror reflector and enter the mirror reflector photoelectric switch. The mirror reflector photoelectric switch controls the two wireless radio frequency transmitting modules to send a first braking signal to the first wireless radio frequency receiving module.

[0020] Furthermore, the remote control device is located within a 1km radius of the vehicle-mounted box.

[0021] The present invention also provides a method for using a portable subway vehicle visual intelligent braking and response device, which is based on any of the above-mentioned portable subway vehicle visual intelligent braking and response devices, and includes the following steps:

In case of an emergency during train operation, the onboard box's emergency stop button and the remote control device can also be manually triggered to activate the emergency braking. The sent "braking signal" simultaneously applies a high-level signal to logic signals such as train traction command disconnection, parking brake application, and brake non-release, effectively blocking traction.
