Patent ID: 7852835

Claim:
A time switch used in a remote monitoring control system in which a manipulating switch wiring appliance for monitoring switch manipulation of manipulating switches, to which individual addresses are allocated, and a remote control wiring appliance for controlling opening or closing of relays, to which individual addresses are allocated, are connected to a signal line, the manipulating switch wiring appliance outputting a transmission signal containing a monitoring input and address information from the manipulating switch to the signal line using a time division multiplexing transmission scheme, and the remote control wiring appliance opening or closing the relays on the basis of the monitoring input of the transmission signal when the address information contained in the transmission signal received through the signal line corresponds with an address of the corresponding relay, in order to turn on or off a load connected to the relay, the time switch comprising: a program storage unit which stores sets of addresses corresponding to the loads to be controlled, control items, and control times of the loads as a time schedule; a setup manipulation unit which sets up the addresses, the control items, and the control times and stores those in the program storage unit as the time schedule; a clock unit which counts a current time; a signal transceiver unit which transmits and receives the transmission signal through the signal line by using a time division multiplexing transmission scheme; and a signal processing unit which prepares the transmission signal containing the addresses and the control items in the time schedule as the address information and the monitoring input and transmits the transmission signal from the signal transceiver unit to the signal line when the control time contained in each set of the time schedule stored in the program storage unit corresponds with the current time counted by the clock unit, wherein the program storage unit, the clock unit, the signal transceiver unit, and the signal processing unit are situated in a switch chassis implanted in a wall surface with its front surface being exposed, and the setup manipulation unit is arranged in the front surface of the switch chassis, and wherein the manipulating switches, to which the addresses registered in the program storage unit are allocated, arranged in the front surface of the switch chassis, and the signal processing unit prepares the transmission signal containing the control item for reversing the turning on or off operation of the corresponding load as the monitoring input by using the address allocated to a switch as the address information and transmits the transmission signal from the signal transceiver unit to the signal line when the manipulating switches are manipulated.
