Embodiment 1
[0041] like figure 1 and Figure 5 As shown, Embodiment 1 of the present invention includes a system that can form wireless reconnection of four locomotives including 2 master locomotives, 3 slave 1 locomotive, 4 slave 2 locomotives, and 5 slave 3 locomotives, so as to construct a remote distribution of wireless reconnection of 1 locomotive. Powered traction running control system. The system is divided into two parts. The first part builds 6 cloud virtual reconnection management levels, and the second part builds 7 locomotive asynchronous cooperative control levels. These two levels are completed by DMU. The first level of each locomotive DMU includes 8 DMU cloud networking and management modules, 9 differentiated cloud adaptation management modules, 10 wireless link management modules, and 11 secure transmission management modules. The second level of each locomotive DMU includes 12 DMU calculation and cooperative control module, 13 wireless communication transmission modu...
Embodiment 2
[0045] like figure 2 As shown, as the first-level cloud virtual reconnection management level (ie, the first level), the remote reconnection networking and real-time information link interaction of four locomotives are constructed through DMU, forming a multi-machine remote reconnection by the cloud. Differentiated management and control are carried out to realize the real-time interaction platform of networking, marshalling and internal information of four locomotives, which are controlled by the master vehicle, and solve the problem of real-time response to the trigger of the slave vehicle. As the second-level locomotive asynchronous cooperative control level (that is, the second level), the main control DMU of each locomotive performs asynchronous control for the local locomotive of the existing locomotive, and completes the coordinated control and traction operation of each reconnected locomotive of the combined train. The invention can also be extended to two, three or...
Embodiment 3
[0047] like image 3 As shown, Embodiment 3 of the present invention includes the system topology connection relationship of the two-segment reconnected locomotives when the system is implemented on a heavy-duty locomotive. The DMUs of the two locomotives perform interconnection information exchange through 26 switch modules (CS). At this time, both DMUs are weak nodes. By default, the main DMU runs in the same direction as the main control locomotive. According to this, the DMU redundancy control module determines that one of the DMUs obtains the control token and becomes the control DMU, and controls, and the other DMU drops. Status monitoring for redundant DMUs. If the master DMU fails and its token is lost, the redundant DMU automatically becomes the master DMU. Including 27 microcomputer display unit module (IDU), 28 braking unit display module (LCD), 29 signal combiner module.
