Coordination system for the mutual coordination of two control parts

摘要

A coordination system comprising a first control part (10) and a second control part (20) which coordinate with each other, wherein: the first control part (10) has a first processing part (11), a transmission part (12, 18) and a first reservation part (17 ) and the second control part (20) includes a receiving part (21, 22) and a second processing part (28); the first processing part (11) includes generation processing for generating a transmission message in a predetermined format relating to coordination processing data used for coordination processing, executes; the coordination processing data contain instant data which are to be shared without delay at least between the first control part and the second control part; the transmission part (12, 18) transmits another transmission message in addition to the transmission message of the instant data; the first reservation part (17 ) the transfer part (12, 18) before the Generation processing of the transmission message of the instant data reserved for transmitting the transmission message of the instant data from the transmission part (12, 18) without delay after completion of the generation processing of the transmission message of the instant data; the receiving part (21, 22) receives the transmission message sent from the first control part; the second processing part (28) extracts the coordination processing data including the instant data from the transmission message received by the receiving part (21, 22), and executes the coordination processing using the coordination processing data; the second The processing part (28) further performs further processing in addition to extracting the coordination processing data from the transmission message received by the receiving part (21, 22) and executing the coordination processing using the coordination processing data; r second control part (20) further includes a second reservation part (27) which reserves the second processing part (28) corresponding to a reception completion time of the transmission message of the instant data in the receiving part (21, 22), so that the second processing part (28) the Executes coordination processing without delay after receiving the transmission message of the instant data representing the coordination processing data; the transmission part (12, 18) carries out a transmission at a fixed time, by means of which a transmission time of the transmission message occurs at a predetermined time interval; the transmission message of the instant Data is transmitted at one of transmission times in the transmission with a fixed point in time; the first reservation part (17) as a reservation of the transmission part (12, 18) an earliest transmission point in time from transmission times necessary for the transmission of the transmission message of the Insta nt data are available, reserved and transmits a planned transmission time corresponding to the reserved transmission time from the transmission part (12, 18) to the receiving part (21, 22); the second reservation part (27) receives the planned transmission time from the receiving part (21, 22) , calculates a reception completion time of the transmission message of the instant data and reserves the second processing part (28) in accordance with the calculated reception completion time; the transmission part (12, 18) a first transmission with a fixed time, through which the transmission time arrives in a short time interval, and at least one a second fixed-time transmission by which the transmission time occurs in a long time interval longer than the short time interval and performs a leisure transmission in which the transmission time arrives in a leisure of the fixed-time transmission; andthe transmission message of the instant data is transmitted at the time of the first fixed-time transmission.
