Abstract

PURPOSE:To use a synchronizing pulse used for transmission communication for measuring time as it is by allowing a terminal equipment receiving a multiple address instruction to execute the control at a delay by a delay time in response to the product between a numeral of its own station address and a period of the synchronizing pulse. CONSTITUTION:A delay time retarding load control is generated by multiplying a numeral set by an own station address setting means 18 with a period T of a synchronizing pulse 22. When a multiple address instruction turning on a load simultaneously is outputted from a terminal equipment 11 to other plural terminal equipments, the load connecting to all terminal equipments is turned on at a time delayed by a multiple of the period T. When the terminal equipment 12 receives a signal, an arithmetic control means 17 checks whether or not the control signal is addressed to its own station. When the control signal is the signal to its own station, the multiple address instruction is used for individual control for its own station only. In the case of the multiple address control, a value of the means 8 is read and a variable (x) is substituted. Then the input of the synchronizing pulse 22 is awaited by (x+1) to generate the delay time. After the (x+1) sets of synchronizing pulses are confirmed, it means that the time elapses by the delay time xT and the load is controlled.

The operation of this embodiment will be explained below. The synchronous clock generating means 20 provided in each terminal is a means that can extremely easily provide a reference value for time measurement in communication using the power line 10 as a transmission communication path. The structure of the control command created by the arithmetic control means 17 will be explained using the signal waveform diagrams shown in FIGS. 2c and 2d. That is, a pulse is provided in the first half between the synchronizing pulses of period T generated by the synchronizing clock generating means 20, and a logic 1 is defined as a pulse in the second half, and a logic O is defined as a pulse in the latter half, and these are combined to form a communication signal. be.

The delay time for delaying the load control is created by multiplying the value set by the local station address setting means 18 by the period T of the synchronization pulse 22. For example, if the own address is number 5, the delay time is 5T, and if it is number 12, the delay time is 12T. The method according to this embodiment is such that the period T of the synchronization pulse is the same for all terminals, and that the own station address value set by the own station address setting means 18 is set to be different for all terminals. This takes advantage of the fact that all terminals have different delay times.

Next, when the terminal 12 receives a signal, the calculation control means 17
The control procedure will be explained using the flowchart shown in FIG. When receiving the control signal, the arithmetic control means 17 first performs processing 2.
In step 5, it is checked whether the control signal is addressed to the own station. Since the control signal generally includes an address indicating a controlled object or information indicating a broadcast command, this is decoded.

If it is determined in step 25 that the control signal is not directed to the own station, this control signal is ignored, the procedure is terminated, and the process waits for reception of the next control signal. If it is a control signal to the own station, go to process 26,
Here, check whether the control is based on a broadcast command or individual control only for the own station. If there is individual control only for the own station, there is no particular reason to delay the control, so the process goes to step 27, where the control is performed immediately and the process ends. If it is broadcast control, go to process 28, read out the value of own station address setting means 18, and set this value to variable X.
Substitute. In process 29, in order to create a delay time (X+1
) waits for the synchronization pulse 22 to be input. (X+1
) synchronization pulses are confirmed, it means that the delay time xT has elapsed, and the process goes to process 27 for the first time, controls the load, and ends. The key idea of this embodiment is to check these (X+1) synchronization pulses. In other words, instead of calculating the delay time xT by multiplication, it is performed by simple addition, and during time xT, (X+
1) It utilizes the fact that 1) synchronization pulses are generated.

In the above embodiment, the delay time is the sum of the synchronization pulse period (T) multiplied by the value (X) of the own station address (xT), but this value is further multiplied by an integer (n x T
