A method and system for configuring regenerative braking energy recovery devices in urban rail transit provided by the present application, successively including the following steps: calculating a preliminarily configured capacity Pof a regenerative braking energy recovery device predetermined for the traction substation n, then obtaining an optimally configured capacity Qof the regenerative braking energy recovery devices; further, configuring the total number of the regenerative braking energy recovery devices; finally, configuring the type of the regenerative braking energy recovery devices. By reasonably configure the capacity and number of regenerative braking energy recovery devices in traction substations, the configuring method of the present application allows the regenerative braking energy generated by a train during braking to be completely absorbed, thus reduce the energy consumption of braking resistors. Meanwhile, the waste of idle regenerative braking energy recovery devices is avoided, and the acquisition cost of devices is reduced. By reasonably configuring the type of regenerative braking energy recovery devices, the deficiencies of a single regenerative braking energy recovery device can be avoided.

Method and system for configuring regenerative braking energy recovery devices in urban rail transit

The present application relates to the technical field of field bus communication, and in particular to a protocol converter between a CPCI bus and an ISA bus and a conversion method thereof, which are suitable for communication between railway vehicle CPUs and vehicle bus MVB devices. The protocol converter comprises a CPCI local bus interface extension timing module, an ISA bus interface timing module, a CPCI bus matching ISA bus timing interface module, and a clock management module. The CPCI bus realizes communication with the ISA bus by the protocol converter. The traditional conversion bridge chips are replaced with the protocol converters without changing the traction controller structure and other devices in the system; the flexibility is high; and the functions are diverse. In addition, 8-bit data width or 16-bit data width of the ISA bus is supported, and the operation of an ISA bus device by a CPCI bus device in the form of IO or in the form of MEMORY is supported.

Protocol converter between CPCI bus and ISA bus and conversion method thereof

The present application relates to the electronic field of railways, and in particular to the traction control system for electric multiple units. A host processor of the traction control system for electric multiple units is connected to a subordinate computer board via a CPCI bus. The traction control system for electric multiple units comprises a fast computing board, a network module and a debugging module. An instruction is passed to the subordinate computer board via the CPCI bus, and meanwhile, the subordinate computer board passes status information to the host processor via the CPCI bus to realize overall control on the interior of the traction control system for electric multiple units. Bidirectional communication between the signal sampling board and the fast computing board is realized by a high-speed differential LinkPort bus to realize quick control on the inverter power module and the four-quadrant power module. Bidirectional communication between the network card and boards of the I/O module is realized by a CAN bus, and digital signals and analog signals sent by boards of the I/O module are transferred to the host processor via the CPCI bus to ensure stability and reliability in information transmission of the traction control system for electric multiple units.
