Abstract

PURPOSE:To easily perform centralized control on the automatic operations of plural devices to be controlled having different operational patterns by providing a centralized control device composed of a timer and centralized controller. CONSTITUTION:The control timer 8 of a centralized control device 5 sets the operational pattern of each group of devices to be controlled 6a-6c. The set operational pattern is stored in the centralized control device 5 as operational pattern information. When the devices 6a-6c are operated, the time information of each stored operational pattern is compared with the time information outputted from the control timer 8. When the times coincide with each other as a result of the comparison, an operation commanding signal is sent in accordance with a group designating signal and the operational pattern information. The operation commanding signal is received by one of the devices 6a-6c belonging to the group designated by the group designating signal and the device is operated under the condition designated by the operational pattern information.

The correct time is corrected and the above display circuit (

FIG. 4 is a flowchart of the operation of the microcomputer (90) of the central controller (9), which is programmed in advance. In this figure, power is first supplied, and after initial configuration (step 100), the interface (9
2) Or input processing of the input data signal from the input circuit (95) is performed (step 101).

From the interface (92), the control timer (
Group-by-group operation pattern information of the controlled devices (6a) to (6C) outputted from the control unit 8) and a time signal are input. The input circuit (95) is operated by an external switch (not shown). 9 normal ON states of the controlled devices (6a) to (6C) that are not based on the determined operation pattern control

Next, in the input process, the controlled devices (6a) to
Regarding the group change or group designation due to the difference in the driving pattern in (6C), it is determined whether there is a change or change in the settings (step 102). If there is a change in the settings, first the above Step 103: Determine whether the group settings have been changed.

becomes possible. If it is determined in step 102 that the group settings are not changed, it is determined whether the change is related to group designation (step 105), and in the case of group designation, group designation transmission is executed (step 1).
01i), if the group is not specified, operation command transmission is executed based on the input information from the input circuit (95) (step 10γ).

Return to step 101.

If it is determined in step 102 that there is no change in the settings, it is determined whether there is data transfer from the control timer (8) (step 108), and if there is no data transfer, the process returns to input processing (step 101). However, if there is a data transfer, it is first determined whether there is a change in the signal indicating the time in the transferred data (step 109), and if the time has changed, the time after this change and the storage means (
Among the driving pattern information stored in 94), the group t A driving command signal including information on the condition change is sent out (step 111).

The operation command signal to which the group designation signal is added from the central control device (5) is modulated into a high frequency signal by the transmitter/receiver circuit (9)K and sent to the transmission line (7), and is sent to the controlled device (
Controllers (5a) to (3) for controlled devices 6a) to (6C)
Among C), only those belonging to a group that matches the group designation signal selectively receive this driving command signal.

For example, if the controlled device (6a) falls under this group, the transmitting/receiving circuit (51a) of the controlled device controller (5a) demodulates the high frequency input signal into a digital signal and inputs it to the microcontroller (50a). , This microcomputer (50a
) determines the operation mode of the controlled device (4a) based on the demodulated signal, and operates the controlled device (4a) via the output circuit (52a).

The transmitting/receiving circuit (51) sends a signal indicating that the controlled device (4a) is being reliably operated based on the operation command signal.
a), modulates it again into a high frequency signal, sends it out to the central controller (91) via the transmission line (71, and transmits it to the transmitter/receiver circuit (9).
The signal is demodulated into a digital signal and input to the microcomputer (90).

Controlled devices (6a) to (9) distributed as described above

N, OFF control operation is also possible. Then, the operation pattern of each group divided into groups based on the difference in the operation pattern of the controlled devices it (6a) to (6C) and the designation of the group are set in advance and the operation is started.
The settings of these driving patterns and group designations can be freely changed during driving.
The controller for each controlled device (
3a) to (5c) K may be provided. Further, although the central control device (5) has been shown as an example consisting of a general timer (8) and a central controller (9), it is preferable that these are constructed in one piece. Also, the central controller (9)
The receiving circuit (91) modulated the digital signal output by the microcomputer (90) into a high-frequency signal and transmitted it to the controlled device controllers (5a) to (5C) via the transmission line (71).
On the contrary, although the case where the high frequency signals transmitted from the controlled device controllers (5a) to (5C) via the transmission line (7) are demodulated into digital signals is shown, the above-mentioned transmitting/receiving circuit (91) and the Controllers for control equipment (5a) to (3C)
It is clear that an electrical and optical digital signal converter may be used instead of those, and an optical signal cable may be used instead of the transmission line (71).Furthermore, in the above embodiment, the controlled device (6a) ~(6C)
Although we have described the case where there are three units, it is clear that this number can be further increased or even reduced to two.
