Abstract

The invention discloses a backplane bus system, a data acquisition method, a data acquisition device and a medium, and the system comprises a backboard substrate which is provided with a plurality of standardized module slots for the insertion of a main control module and a plurality of acquisition modules; the backplane bus structure comprises a low-bandwidth control bus and a high-bandwidth one-way data bus, the data transmission rate and power consumption of the low-bandwidth control bus are lower than those of the high-bandwidth one-way data bus, and the high-bandwidth one-way data bus supports various different transmission rates; each acquisition module determines the uplink bus transmission rate of the acquired data according to the own acquisition capability and the maximum bandwidth, and the main control module receives the acquired data uploaded according to different uplink bus transmission rates. According to the invention, on the premise of ensuring compatibility of high and low rate signals and supporting flexible expansion, dynamic balanced distribution of power consumption is realized, the overall power consumption of the system is reduced, the load concentration problem of the main control module is relieved, and the energy efficiency ratio and the operation stability of the system are improved through an asymmetric communication design and an adaptive control mechanism.
