Abstract: 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.

Abstract: A communication apparatus installed in the trains and that in a complex station building, a station or a maintenance factory communication through feeders, trolley wires or third rails can communicate each other. The present invention can realize a low cost vehicle-facility intra communication system that provides various information services available in the train.

Abstract: A passenger detection loading and unloading control system is provided for high volume passenger transporters such as subway trains and the like which electronically counts the passengers in each passenger compartment and prepositions passengers that intend to deboard at the next passenger loading and unloading platform and which electronically counts and prepositions a number of passengers at the next platform for boarding. The system further permits simultaneous loading and unloading of passengers without interference with passenger flow. Passengers on the transporter are numerically counted and those passengers intended to deboard the transporter at the next platform are also counted. Signals representing these counted passengers are continuously transmitted to a signal processing facility for processing. A predetermined time schedule for arrival and departure is established for the high volume passenger transporter in relation to each passenger loading and unloading platform.
