Description
Technical Field

The emergency stop button is allowed to be used only under extreme working conditions, and is the last line of defense for train safety protection.
For traction and cutting, a traditional wheel-rail train drives a rotating motor to traction a vehicle through a traction converter on the vehicle, a traction system of the traditional wheel-rail train is installed on the vehicle, and an emergency stop button is used for traction and cutting of the vehicle through a wire harness on the vehicle. The high-speed maglev train is driven by a linear motor long stator on the ground to run in a suspension mode, a traction system of the high-speed maglev train is arranged on the ground, and an emergency stop button is installed on the high-speed maglev train and is far away from the ground traction system. The emergency stop device of the conventional wheel-track vehicle cannot realize the function of controlling, dragging and cutting of high-speed magnetic suspension traffic.

Therefore, the emergency stop device of the conventional wheel-track vehicle cannot realize the function of controlling the emergency brake of the high-speed maglev train traffic.
In view of the above, there is a need for an emergency stop system for a high-speed maglev train, which can respond to the emergency stop needs of a driver or a passenger to perform traction cutting and emergency braking on the high-speed maglev train, so as to solve the emergency stop control problem of the high-speed maglev train.

The vehicle-mounted safety computer is connected with the eddy current brake controller through a vehicle-mounted control network. It can be understood by those skilled in the art that the vehicle-mounted control network refers to a control private network composed of vehicle-mounted controllers and related devices, and is used for issuing vehicle control commands. The eddy current brake controller is used for controlling the eddy current brake electromagnet, so that the eddy current brake controller responds to a braking command sent to the eddy current brake controller by the vehicle-mounted safety computer through the vehicle-mounted control network, drives the eddy current brake electromagnet to perform eddy current braking, and stops the train in a braking mode.
Please further refer to fig. 3 to understand the traction cutting device provided by one aspect of the present invention. As shown in fig. 3, the traction cutting device comprises an emergency stop triggering device, a vehicle-mounted safety computer, a vehicle-ground wireless communication device and a ground operation and control device.

Meanwhile, the vehicle-mounted wireless communication devices among the vehicle-ground wireless communication devices are redundantly provided at the head compartment and the tail compartment, respectively.
The connection relationship between the emergency stop triggering device and the vehicle-mounted safety computer is already described above, and is not described in detail herein. And when any one of the redundant vehicle-mounted safety computers receives the emergency stop instruction, the traction cutting signal is transmitted to the ground wireless communication device through the corresponding vehicle-mounted wireless communication device. The ground wireless communication device sends a traction cutting signal to a traction cutting computer in a traction system through a ground partition safety computer, so that traction equipment is controlled to implement traction cutting, and the current output of the traction equipment is blocked.
With the embodiment as shown in fig. 3, in response to the scram trigger outputting the scram command, the on-board safety computer can output the traction cutting signal to a ground operation control system located on the ground through the on-board wireless communication device, so that the traction system on the ground can be operated in response to the scram trigger.

The specific implementation manner of the vehicle-ground wireless communication device can be implemented in an existing or future manner, and the protection scope of the invention should not be unduly limited to the specific implementation manner of the vehicle-ground wireless communication device.
Another aspect of the present invention provides another preferred embodiment of a traction resection device, and reference is made to FIG. 4 for an understanding of another preferred embodiment of a traction resection device provided by another aspect of the present invention. As shown in fig. 4, in the preferred embodiment, the traction cutting device includes an emergency stop trigger, a traction cutting signal generator and a traction system in the ground operation control system.
The traction cutting signal generator further comprises a traction cutting vehicle-mounted signal transmitting end positioned on the train and a traction cutting ground signal receiving end positioned on the ground. The distraction system further includes a distraction ablation computer and a distraction device.

The redundant traction cutting vehicle-mounted signal transmitting end is connected with the emergency stop triggering device, so that an emergency stop instruction output by the emergency stop triggering device can be received. The traction excision ground receiving end is directly connected with a traction excision computer in the traction system.
And responding to the fact that any one of the redundant traction cutting vehicle-mounted signal transmitting ends receives the emergency stop command, and the traction cutting vehicle-mounted signal transmitting end which receives the emergency stop command outputs a traction cutting command to a traction cutting ground signal receiving end through wireless communication. After receiving the cutting instruction, the traction cutting ground signal receiving end directly outputs the cutting instruction to a traction cutting computer in a traction system, so that traction cutting can be implemented through the traction cutting computer, and the output current of traction equipment is blocked.
In the embodiment, the emergency stop command output from the emergency stop triggering device can be more rapidly converted into the traction cutting command for controlling the ground traction system, so that the traction cutting device has better response speed.
It can be understood that, in the embodiment shown in fig. 4, the redundant traction cut signal transmitting terminal may be connected to a plurality of normally closed switch circuits formed by a plurality of emergency stop triggering devices, so that the response speed of the emergency command can be improved through the normally closed switch circuits.
In the embodiment shown in fig. 4, since an additional traction-off signal generator is required, although the cost of the entire system is increased, the wireless communication device can be selected separately from the original train-ground wireless communication device, and the latest generation communication device can be selected, for example, a traction initial signal can be transmitted through a 5G network, so that the response speed of the entire system can be increased.
In a further preferred embodiment of the emergency stop system, the output of the emergency stop trigger device can be connected to the on-board safety computer and the traction-cut generator at the same time, so that the entire emergency stop system has redundant traction-cut devices, so that traction-cut can be ensured.
