Problems solved by technology

However, due to the particularity of the vacuum tube rail train in terms of operating speed and operating mode, the existing one or two combined braking single braking strategy mode is adopted, and the braking strategy is not flexible. When the situation (such as the failure of the traction power system), the safety of the single braking strategy mode is low, and the existing braking method has a long braking distance

Embodiment 1

[0052] The present invention as figure 1 As shown, a combined braking system is provided, including a regenerative braking module, an air braking device, an eddy current braking device, a mechanical braking device and a multi-braking strategy controller.

[0053] The multi-braking strategy controller includes a running speed monitoring module, a braking status analysis module, a traction power system working state monitoring module and a braking strategy control module. The running speed monitoring module is used to monitor the running speed of the transportation vehicle in real time; the braking status analysis module judges whether it is normal braking or emergency braking according to the braking signal sent by the main control system of the transportation vehicle, and sends the judgment result to the braking strategy Control module; the traction power system working state monitoring module monitors the traction power system working state in real time, and sends the tractio...

Embodiment 2

[0062] The present invention also provides a combined braking method, such as Figure 5 shown in the following steps:

[0063] 1. The means of transportation are in normal operation;

[0064] 2. Judging the braking status of the transport vehicle and determining the braking strategy to be adopted, if it is normal braking, go to step 3, if it is emergency braking, go to step 4;

[0065] 3. Adopt braking strategy 1,

[0066] The first braking strategy adopts the combined braking mode of regenerative braking and air braking; regenerative braking and air braking are activated at the same time.

[0067] 4. Judging whether the traction power system works effectively under emergency braking, if it can work effectively, go to step 5, if not, go to step 6;

[0068] Step 5, adopt braking strategy 2,

[0069] The second braking strategy adopts the combined braking mode of regenerative braking, air braking and eddy current braking; regenerative braking, air braking and eddy current br...
