Title:
DATA CONVERTER, SIGNAL TRANSMISSION METHOD, AND SIGNAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/146898
Kind Code:
A1
Abstract:
A data converter, a signal transmission method, and a signal transmission system for transmitting a signal to a programmable logic controller are provided. The data converter: performs sampling a plurality of number of times with respect to data detected by a sensor in one communication period in which communication is performed with a programmable logic controller; acquires statistical data by maintaining statistics of a plurality of pieces of sampling data in the communication period; and transmits the statistical data to the programmable logic controller when the communication period is reached. On the basis of an embodiment of the present invention, a signal sampling density is improved, and thus control accuracy can be enhanced. At the same time, a data transmission amount of a bus is reduced, a load on the programmable logic controller is reduced, and user convenience is improved.
