Title:
DATA TRANSMISSION PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2590635
Kind Code:
B2
Abstract:
PURPOSE: To allow a secondary station to send a newest data in response to a transmission request from a primary station even when a polling interval is long with respect to the data transmission processing system in which the secondary station connected by the central control system/branch system sends a data to the primary station by an HDLC/NRM protocol through a communication line.
CONSTITUTION: The method is provided with a data input processing 1 which overwrites an inputted data to an input buffer 11 to hold a newest data, a data composition processing 2 using a data in the input buffer 11 to compose a transmission data, a data transmission processing 3 storing the composed data to a transmission buffer 31 and sending the data via a driver 6, a transmission reception end notice processing 4 detecting the end of transmission reception in the driver 6 and a timer monitor processing 5. The timer monitor processing 5 monitors the polling interval to calculate the timing of the data composition period from the polling interval and makes a request for the data composition processing.
