TRANSMISSION SYSTEM FOR TIME DIVISION MULTIPLEX SIGNAL

摘要

PURPOSE:To improve response speed at the time of controlling plural loads by providing a return period setting signal for setting the return standby period of load monitor data sequentially returned from the respective terminal equipments of a terminal equipment group in the rear end of a transmission signal of a pattern control mode. CONSTITUTION:The transmission signal Vs for controlling the pattern for transmitting a data signal DT consisting of mode data MD for setting a control mode to the pattern control mode, the leading address data AD'' of the terminal equipment group to which an integrally pattern controlled load is connected, data BD1 indicating the number of transmitted control data CD1-CDn, the control data CD and check sum data SD and the return period setting signal WT is transmitted from a central control unit. The respective terminal equipments receiving the control data CD1-CDn recognize that the data is normally received based on the check sum data SD, and then return receiving recognition signals Vb1-Vbn synchronously with the return standby periods T1-Tn assigned to themselves during the return standby period T set by the return period setting signal WT.
