Abstract

PURPOSE:To shorten a data transmission time by assigning different address to respective terminal equipments to transmit data only to the corresponding terminal equipment, and also assigning an address common to respective terminal equipments to transmit data simultaneously to all the terminals. CONSTITUTION:The terminal equipments 3 turn on and off their lamps in accordance with data applied from a control circuit 1 through a transmission line. Addresses such as '0001' and '0010' different in respective terminals and a common address '0000' are set up in the terminals 3. When a lamp On data is transmitted together with an address '0010' from the control circuit 1, the data are read into the terminal 3 having the address No. '0010' and a lamp connected to the terminal 3 concerned is turned on. When a lamp OFF data are transmitted together with the address '0000' from the control circuit 1 to a transmission lione 2, the data are read into all the terminals 3, 3- and all lamps in the home are turned off.

口) Conventional technology Conventionally, in a system in which many terminals controlled by a control circuit at a center are connected, for example, when sending the same data from the control circuit to all terminals, it is necessary to specify the address number of each terminal in sequence. A method was adopted in which the same data was sent to each terminal.

C) Problems to be Solved by the Invention By the way, in such a data transmission system, as mentioned above, even if the data is the same, data must be sent to each terminal, which increases the overall transmission time. When such a data transmission system is used in a lighting control device that centrally manages the lighting status of lights in the home and a command is issued to turn on or off all the electric lights, all the electric lights are turned on or off. There was an inconvenience that the reaction time "m" until the reaction was delayed.

E) Function: By sending data with a different address for each terminal, data is transmitted only to the corresponding terminal, and at the same time, data is sent by assigning a common address to each terminal. The same data is transmitted to all terminals at the same time. Therefore, the data transmission time when transmitting the same data to all terminals is shortened.

g) Effects of the Invention As mentioned above, the data transmission system of the present invention provides each terminal with a different address and a common address for all terminals, so it is not possible to assign a different address to each terminal. At the same time, by attaching a common address to each terminal and transmitting data, data can be transmitted to all terminals at the same time, and the same data can be sent to all terminals. When used in a home lighting control system, the response time to an all-electrolytic ON or all-electrolytic OFF command is shortened.
