TOY SYSTEM

摘要

A digital slot car racing system is described which allows multiple slot cars (3 - 1 to 3 - 6) to be raced on each slot (11) of a slot car racing system. The system includes a main controller (7) which is arranged to transmit digital messages to each of the slot cars by modulating the signal applied to the slots. The slot cars are operable to use the signal applied to the slot to derive power for powering the slot car and to recover the data transmitted from the main unit. The slot cars extract the relevant data and control the speed of the slot car. The slot car racing system also includes a number of change lane track segments (351) which allow slot cars to change slots. In operation, the main unit transmits a change lane request to a slot car which, in response, transmits a signal to the change lane track segment indicating that it wants to change slot. A change lane controller then opens a gate on the change lane track segment to cause the approaching slot car to be directed onto the other slot.
