Abstract: A time-sharing wave recording method is provided. Firstly, N1 operating variables are selected, and the storage addresses of the N1 operating variables are mapped to N1 index variables. Then, N2 record channels in a sequential relationship are provided, and a mapping relationship between each record channel and the N1 index variables is established. Then, the values of the operating variables are assigned to a first record channel of the N2 record channels in response to a rising edge of a pulse of a clock signal and a start triggering signal, the values of the operating variables are sequentially assigned to the rest of the N2 record channels in response to a rising edge of each pulse of the clock signal and the start triggering signal, and the assigned values of the operating variables for the N2 record channels are recorded to the memory.

Abstract: The present application provides a multi-unit cooperative distributed electrical control system and an electrical system. The control system includes multiple type-I embedded control units and at least one type-II embedded control unit, and a type-I embedded control units communicates with another type-I embedded control unit through the at least one type-II embedded control unit. A first type-I embedded control unit generates, according to functional information stored therein, a functional data packet, and then forwards the functional data packet to an adjacent second type-I embedded control unit through the type-II embedded control unit, so that the second type-I embedded control unit determines whether the received functional data packet passes a checking; if passed, the second type-I embedded control unit performs a corresponding operation; if not passed, do not perform a corresponding operation or it is determined that the functional data packet is abnormal.
