Disclosed are a real-time bus and an implementation method therefor. The method comprises the following steps: an uplink bus is composed of a plurality of first buses, and the first buses are connected to a plurality of single boards and is connected to a common single board; a downlink bus is composed of a plurality of second buses having identical transmission rates and contents, the second buses one-to-one correspond to the first buses, and the second buses are connected to a plurality of single boards separately and are connected to the common single board; each single board outputs information within a corresponding timeslot and transmits the information to a data forwarding unit, via the uplink bus, for receiving, and other time periods are high in resistance; and the data forwarding unit collects the received information, forwards the information to a timeslot corresponding to each single board on the downlink bus, and forwards downlink data of all the single boards to the downlink bus, and each single board receives the downlink data within the corresponding timeslot. The present invention has the advantages of simple structure, low cost, strong real-time performance, large quantity of connected single boards and the like, decreases the quantity of interconnected wires of a backboard, reduces the costs of the backboard and a connector, and improves the reliability of a device. The inventor shall check it carefully. |
