Novel cascaded bus communication connection architecture and related system

The utility model discloses a novel cascade bus communication connection architecture and a related system, the architecture can comprise a main device, N node devices and a Bus, N is a positive integer greater than 1; the bus output positive electrode end of the main device equipment is coupled with the positive electrode input ends of the N node equipment in parallel through a Bus; the bus output negative electrode end of the main device equipment is serially coupled with the negative electrode ends of the N node equipment through a Bus; the working state of any node in the N node devices is controlled by the previous-stage device. According to the novel cascade bus communication connection architecture provided by the embodiment of the utility model, a plurality of node devices can be added under the condition that the quality of communication signals is not influenced, and the node devices in the embodiment of the invention adopt an alternate working mode, so that the power consumption of the communication architecture can be reduced.
