Large-scale temperature control network matrix type dual-channel real-time constraint method

Abstract

The invention discloses a large-scale temperature control network matrix type dual-channel real-time constraint method. The method comprises the following steps of resolving a delay error by using tworadio frequency signals as carriers; synchronizing clock signals of two places by using a star topological structure, time calibration and a central node working process; and detecting radio frequency signal transmission and realizing delay error synchronization. In the invention, two radio frequency signals with different frequencies lambda 0 and lambda 1 are used as the carriers; one path of radio frequency signal with a wavelength of lambda 0 is used as a reference signal; one-way transmission delay from a reference temperature control module to a target temperature control module in a matrix formed by the large-scale temperature control module is measured; and the star topology structure is adopted to finish time synchronization between a slave station located at a certain sub-node and a master station located at a central node, and time synchronization of the whole large-scale temperature control network is realized so that time delay error synchronization of the whole large-scale temperature control system is realized, and temperature control signals are accurately constrained.
