They each have

The first transistor (21) is connected to the first photocoupler (+41
This series circuit is placed between the 12V positive pole of the DC power supply and the ground pole, while the first photocoupler circle connects the phototransistor to the diode (43) in series through a resistor (43). OP U [2

Therefore, when the first transistor 121) operates and becomes conductive, both baud (04) and (R4) become conductive, and the operation signal or stop signal is output from the OPU +21 in the same way as the operation switch (8) on the hand side. You will be able to do it.

Therefore, the base of the first transistor (211) has one end grounded and the other end of the individual operation switch (4-) connected to the base of the first transistor (211).
The R circuit is connected via the NOT circuit (29), and the other end is the NOT circuit (to), the all-room start switch (4-0) with one end grounded, and the ring counter Q3], NAN

Or by configuring the first transistor! 211
il, the individual operation switch (4-,) is operated to close, the all-room start switch (4-o) is operated to close, and the "H" signal is output from the ring counter 03.
The photocoupler 06) is in an inoperative state (the air conditioner (1-, ) is stopped as described later), the all-room stop switch (4-8) is closed, and the NOT circuit (3η) is activated. "H" signal is output and the third photocoupler 06
) is in an operating state (air conditioner (1+) is operating).
Therefore, the closing operation (run or stop operation) of the individual operation switch (4 one side), and the closing operation (operation operation) of the all-room start switch (4o) when the air conditioner (1-,) is stopped.
, when the air conditioner (1+) is operating, the first transistor is activated by either the closing operation (stopping operation) of the all-room stop switch (4s)! 21) becomes conductive and operates OPU i21.

In addition, the NOT circuits (3η and 08) are connected to each control board section (U2 on one side) to (12
(on the other hand), and a stop switch for all rooms [4-I
II] and H are connected in series to the all-room start switch (4-0), respectively.

Next, the second transistor Qz connects fiUB in series to the photodiode of the second photocoupler 05) via a resistor (39).
This series circuit is arranged between the 12VIE pole of the DC power supply and the ground pole, while the second photocoupler 05
) to ground the emitter of the phototransistor, and connect the collector to the CPU 2) through a high resistance 40). 7) terminal [Z] VC are connected respectively.

Therefore, when the second transistor 2z operates and becomes conductive, I
Since the terminal [Z] of the C matrix (7) is grounded and becomes the "L" level, the signal from the port (04) of the OP U 121 is no longer input to the IC matrix (7), and the signal is not input to the local operation switch (8). ) becomes ineffective. On the other hand, in this case, when the first photocoupler 04) is activated by the electrical signal from the central controller (3) side, the signal from the port (0,) becomes ineffective.
It will be sent to Baud (R,) via the phototransistor 41 and the diode (43).

As is clear from the above operation, when the second transistor conducts, the operation from the central controller (3)
The stop signal is transmitted to the air conditioner (knee heavy) via OP U F21, but operation from the local operation switch (8)
Stop signals are cut off to facilitate transmission.

The base of the second transistor (2z) is connected to the normal output terminal of the flip-flop (35) via a NOT circuit, and the flip-flop 5) connects the normal output terminal to the NQT circuit 63. ) and individual room indicator lamps (9-ρ), which are connected to the 12V positive terminal of the DC power supply via light emitting diodes, and the inverted output terminal '1N
It is connected to the 127 positive pole of the DC power supply via the OT circuit diagram and a light emitting diode which is an individual central indicator lamp (10-s).

To one input terminal of the above-mentioned flip-flop, all 41 of the NAND circuit e circuits are connected to the other ends of the individual centralized switch (5-,) whose one end is grounded and the collective centralized switch (5-o), and the other end is connected to one input terminal of the flip-flop. Input terminals include individual room switches (6-,) with one end grounded and collective room switches (6-o).

By configuring the second transistor as an individual lumped switch (5-,) or a lumped lumped switch (5o)
When the is closed and the normal output terminal on the flip-flop side is held at the "L" level, conduction is activated, and on the other hand, the individual chamber switches (6-one) or the collective chamber switches (6-o)
When the flip-flop (35) is closed and the normal output terminal of the flip-flop (35) is held at the "H" level, it becomes inactive.

The third photocoupler α6) is a relay element for monitoring as described above, and the input side diode is connected to the air conditioner (1).
-, ) are connected during air conditioning operation, and a diode (4 diodes and a resistor (36) are connected in series to the transistor on the output side between the 12V JIE pole of the DC power supply and the ground pole. It is connected across.

Then, the emitter of this transistor'(i-, NA
As mentioned above, the ND circuit Qη and the NOT circuit are connected to each other, and are further connected to the ground terminal of the light emitting diode that is the individual operation indicator lamp (,11-,) via the NOT circuit. .

The control board section (12-,) is further provided with a changeover switch f171, and the blocking side terminal of the diode of the changeover switch t17]i-[second photocoupler f15] 3rd photocabra u61
A diode (411 column) is provided between the emitter of the transistor Cτ and the emitter of the transistor Cτ. It is operated to close when it is desired to restrict the operation.

That is, when the changeover switch Q71 is opened as shown in the figure, if the second transistor is conducting, the second photocoupler [15] is activated regardless of whether the air conditioner CI+ is in operation or stopped. As mentioned above, the push operation of the operation switch (8) on the hand side is disabled, and neither the operation signal nor the stop signal can be output by operating the operation switch (8) on the hand side. On the other hand, when the changeover switch αη is closed, the air conditioner (
1-,) is in operation and the third photocoupler 16) is in operation, the blocking side terminal of the diode in the second photocoupler 05) is held at the "H" level via the changeover switch 07I, and as a result, the second transistor (Even if 2z is conducting, it is possible to keep the second photocoupler (15) inactive, and therefore the air conditioner (1-,)
Only when the CPU is running, an electric signal is activated by pressing the operation switch (8) on the hand side, and the CPU is used as a stop signal.
121, it can be transmitted to the air machine (11) as a stop output, and by opening the selector switch 071, the operation switch on the local side (
8) The electric signal is invalid for both operation signal and stop signal υ,
Conversely, only the operation signal can be invalidated by the closing operation.

As is clear from the above explanation, the second photocoupler 0
5), third photocoupler (16) and changeover switch 07
1, it is activated by operating one of the central control switch (5) and the central control/room control switch 6), and is deactivated by the operation of the other, and when the central control switch (5) is operated, the local operation is activated. switch (all of the 8 electrical signals or those corresponding to operation signals are processed by the processing device + 21)
It constitutes a restraining means (18) that restrains the material from being introduced.

To explain the outline of the operation of the device having the above-mentioned steaming configuration, press any switch (6-
, ), (6-o) are closed, both the second transistor and the second photocoupler α5) are inactive, and when the individual operation switch (4-, ) or the local operation switch (81) is pressed, If the air conditioner (11) is stopped, it will serve as an operation signal and the air conditioner (11) will operate; on the other hand, if it is running, it will serve as a stop signal and the air conditioner (1) will start operating.
stops.

In this case, it is stopped and the collective switch for each room (6o)
When the all-room start switch (4-o) is closed, the operation signal is transmitted to each air conditioner C1- through the ring counter Q3, the first transistor, and the first photocoupler α4I. , ) to [1-n), but for air conditioners that are already in operation, NAN is given.
Since the D circuit (26) prevents the first transistor (21) from emitting an output, an operation signal is emitted only when the device is stopped.

In addition, the ring counter port 31 has a large number of air conditioners (one on one side)
~(l n) k-In order to prevent them from starting up all at once, the control board units (12-,
) to (12-n) in order.

10,000, When all or a majority of the air conditioners (1-,) to (1-1) are operating, if the collective room switch (6-o) is closed, the all room stop switch (4s) f When the closing operation is performed, the first transistor (2ta, first photocoupler α4) corresponding to the operating air conditioner is activated,
It is possible to generate a stop signal and stop all at once.

Next, switch any switch (5) of the central management switch 15).
-, ), (5o) is operated to close the second transistor, and when the selector switch αη is opened, the second photocoupler 15) is activated, the second transistor 2z is operated, and the selector switch 071 is opened. If it is open, Ha,
As a result of the second photocoupler α5) operating in synchronization with the second transistor, the individual operation switches (4-, ) can be used to stop the operation, the all-room start switch (4o) can be used to collectively start the stopped items, and the all-rooms stop switch ( 4s), it is possible to stop all running devices all at once.・Operation of the operation switch (8) on the air conditioner side (ζ
transmission is restricted.

Therefore, operation is performed only on the central controller 13) side.
Stop is operational.

II. For those with the changeover switch 0η closed, the second photocoupler 05) is inactive when the air conditioner is running and activated when the air conditioner is stopped, so press the local operation switch (8). Even if it is operated, the one corresponding to the stop signal is valid and the one corresponding to the operation signal is invalid, so that only the stop operation is possible.

In this way, the operation of the air conditioners can be easily divided into priority management by the central controller (31) and concurrent management by the central controller (3) and each room, and moreover, each air conditioner (l t
) to (l-ゎ), by simply operating the changeover switch 07), it is possible to select full restriction of start/stop operations or partial restriction of only driving during priority management on the centralized side.

(Effects of the Invention) As is clear from the above description of the present invention, it is possible to control the air conditioners to start and stop in parallel from either the central control side or the local side of each room, and the local side Therefore, it is possible to restrict starting and stopping so that neither starting nor stopping is possible, or to perform priority starting/stop control on the centralized control side while restricting only the starting operation. - Appropriate operation management can be carried out rationally, quickly, and smoothly depending on the presence or absence of an operation manager and the state of the location of the operation manager.

Furthermore, in the case of centralized management, by making it possible to stop the air conditioning operation in each room on the user side, there is an advantage of avoiding unnecessary operation and achieving high economic efficiency.
