Abstract

An embodiment of the present invention provides a responsive communication method and system, the method comprising: sending the current output data information to the motherboard, so that the motherboard generates a response request and an ATP action instruction according to the current output data information; receiving the ATP action instruction , to execute the ATP action command to realize ATP control; receive the response request, and feed back the output data information of the next cycle to the motherboard according to the response request. The responsive communication method and system provided by the embodiments of the present invention, on the basis of existing communication, increases the response mode of each execution board to passively reply a message to the main board, so that each execution board can selectively reply the latest news to the main board, The data processing amount of the motherboard is effectively reduced, the efficiency of data processing is improved, and the communication quality is optimized.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a responsive communication method and system. Background technique [0002] In the rail transit system, the safety computer platform can adopt the Powerlink communication method, and its specific communication link includes: the master node (communication control board) in Powerlink will send a response to other boards in each communication cycle (such as 2ms) Signal (Preq for short) data frame; after receiving the Preq data frame sent by the master node, each executive board will broadcast the Preq data frame to the bus if there is currently data to be sent to other boards for the purpose Nodes retrieve data from the bus by themselves. [0003] Boards can be divided into motherboards and executive boards according to their functions, and executive boards can be subdivided into signal boards, input boards, and output boards. Among them, the main board carries the operation...
