Abstract

PURPOSE:To make it possible to properly use a priority starting and stopping control by a central controller or an equilevel starting and stopping control by the central controller side and individual room side by selectively manipulating a central control switch and a central individual room control switch. CONSTITUTION:When a central-individual room control switch 6 is closed and an individual operation switch 4-1 or a local operation switch 8 is pushed to operate, if an air conditioner 1-1 is in stop, it is operated, while, if the air conditioner 1-1 is in operation, it is stopped. In this case, by closing a collective individual-room switch 6-0 and an all-room starting switch 4-0 during the stoppage of the air conditioner an operation signal is emitted to only those in stop by a NAND circuit 26. A ring counter 13 is for successively starting a large number of air conditioners. By closing an all-room stop switch 4-s, all air conditioners can be stopped. Next, when a central control switch 5 is closed, the operation and stoppage of the air conditioner can be made only on the central controller 3 side. Thus, the operation of the air controller can be performed easily and property by selectively using the priority control by use of the central controller 3 and concurrent control of the central controller 3 and individual rooms.

The internal circuit of this centralized controller (3) will be explained below. 1
1 board part (12+) to (12-,) and each air conditioner (i-I
) to (1-n) and a DC constant voltage power supply (not shown), and each control board section (12-, ) to (12-n) has the same configuration. Therefore, to explain one of them (12-,), the output section that transmits the signal to the CPU (2) side of the air conditioner (1+) is equipped with a first photocoupler (14) for the start/stop signal. , is equipped with a second photocoupler (15) for centralized control (to restrict the start/stop operation on the air conditioner 1! (1-,) side), The monitor input terminal for receiving driving signals from the side is equipped with a third photocoupler (16) for monitoring.

Furthermore, a first photocoupler (14) for controlling the first photocoupler (14)
It is equipped with a second transistor (22) for controlling the transistor (21) and the second photocoupler (15), and each logic circuit (24) to (31) and a flip-flop (35), an N07 circuit (32) associated with the phototransistor of the third photocoupler, an N07 circuit (33) associated with the output terminal of the flip-flop (35), (34) respectively.

The first transistor (21) is the first photocoupler (14)
The first photocoupler (14) connects the phototransistor in series through a resistor (23), and this series circuit is placed between the 12V positive electrode of the DC power supply and the ground electrode. CP via (43)
U (both the predetermined ports (04,) of 21, (R
t) Connected across the gap.

Therefore, when the first transistor (21) operates and becomes conductive, both ports (04) and (R4) become conductive, and the operation signal or stop signal is sent from the CPU (2) in the same way as the local operation switch (8). will now be output.

Therefore, the base of the first transistor (21) has one end connected to the ground, and the other end of the individual operation switch (4-1) connected to the base of the first transistor (21).
All-room start switch (4-0) connected via R circuit (2B) and N07 circuit (29) and grounded at one end
) is the N07 circuit (3B), the ring counter (13), the NAND circuit (26), and the OR circuit (28).
) and the N07 circuit (29), and the other end of the all-room stop switch (4-s) whose one end is grounded and the emitter of the phototransistor of the third photocoupler are connected to the NAND circuit (27) and the OR It is connected via the circuit (28) and the N07 circuit (29), and the emitter is connected to the N07 circuit (31) and the NAND circuit (
26), are connected via an OR circuit (28) and an N07 circuit (29).

(by configuring the first transistor (21)
The individual operation switch (4+) is closed, the all-room start switch (4-0) is closed and the rHJ signal is output from the ring counter (13), and the third photocoupler (16) is inactive (as described later, the air conditioner (
1+) is stopped), the all-room stop switch (4-,) is closed and the rHJ signal is output via the N07 circuit (37), and the third switch (16) is activated. The conduction is activated depending on one of the three conditions (state in which the air conditioner (1-,) is operating), and therefore, the closing operation (running or stopping operation) of the individual operation switch (4-,) is activated. ), closing operation of all room start switch (4-,) when air conditioner (1-,) is stopped (operation operation)
, when the air conditioner (i-+) is operating, the first shut-off switch (4-) is closed (stopped).
The transistor (21) conducts and the CPU (2)
It activates the.

In addition, the N07 circuit (37) and (3rd) are connected to each control board section (12-1) to
(12-n) and all room stop switches (
4-, ) and the all-room start switch (4-0), respectively.

Next, the second transistor (22) is connected to the second photocoupler (1
The photodiode (5) is connected in series through a resistor (39), and this series circuit is placed between the 12V positive pole of the DC power supply and the ground pole.
5) grounds the emitter of the phototransistor and connects the collector to the TCPU (21(
7) The port (o4) is also connected to the terminal (Z) of the IC matrix (7) via the low resistance (41).

Therefore, when the second transistor (22) is activated and conducts, the terminal (Z) of the IC matrix (7) is grounded and becomes "L".
” level, CPU (2) (7) port (o4
) is not input manually to the IC matrix (7), and the electric signal from the local operation switch (8) becomes ineffective, while in this case the central controller (3)
When the first photocoupler (14) is activated by an electric signal from the side, the signal from the photocoupler (04,) is transferred to the port (R4) via the phototransistor and diode (43) of the photocoupler (14). It will be sent to.

As is clear from the above operation, the second transistor (2
2) conducts, the operation and stop signals from the central controller (3) are sent to the air conditioner (1') via the CPU (2).
+), but the operation and stop signals from the operation switch (8) on the hand side are cut off and no longer transmitted.

Therefore, the non-inverting output terminal of the flip-flop (35) is connected to the base of the second transistor (22), and the N07 circuit (3
0), and this flip-flop (35
) connects the normal output terminal to the 12V positive pole of the DC power supply via the N07 circuit (33) and the light emitting diode that is the individual room indicator lamp (9-, ), and connects the inverted output terminal to the N07 circuit. (34) and individual concentration display lamps (
10-1) of the DC power supply through the light emitting diode.
Connected to 2V positive terminal.

One input terminal of the flip-flop (35) has
The other end of each of the individual centralized switch (5-,) and the collective centralized switch (5-0) with one end grounded is a NAND circuit (24)
The other end of each individual room switch (6-,) with one end grounded and the collective room switch (6-0) are connected to the other input terminal via a NAND circuit (25). ing.

With this configuration, the second transistor (22) can be configured as an individual centralized switch (5-1) or a collective centralized switch (
5-0) is closed and the normal output terminal of the flip-flop (35) is maintained at the rLJ level, conduction is activated, while the individual chamber switches (6-, ) or the collective chamber switches (6-0) are closed. -0) is closed and the flip-flop (35
) becomes inactive when the normal rotation output terminal is held at rHJ level.

As mentioned above, the second photocoupler (16) is a relay element for monitoring, and the diode at the input end is connected to the air conditioner l1.
While 1 (It) is operating the air conditioner, i! ! ! The transistor on the output side is a diode (4
4) and a resistor (36) in series to connect the DC power supply to 12V.
It is connected across between the positive electrode and the ground electrode.

Then, connect the emitter of this transistor to a NAND circuit (
27) and the N07 circuit (31) as described above, and is further connected to the ground side terminal of the light emitting diode which is the individual operation indicator lamp (11-,') via the NOT circuit (32). are doing.

The control board section (12-1) is further provided with a changeover switch (17), which connects the blocking side terminal of the diode of the second photocoupler (15) and the third A diode (45) is connected between the emitter of the transistor of the photocoupler (16).
The second photocoupler (15) is connected to the air conditioner 1! (1-+) is operated so as to be closed when it is desired to be restrained from operating.

That is, when the changeover switch (17) is open as shown in the figure, if the second transistor (22) is conducting, the second transistor Since the photocoupler (12) is kept in the operating state, as mentioned above, the push operation of the hand-side operation switch (8) is disabled, and both the operation signal and the stop signal are transmitted to the hand-side operation switch (8). On the other hand, when the changeover switch (17) 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 (15) is held at the rHJ level via the changeover switch (17), so that even if the second transistor (22) is in conductive operation, It is also possible to keep the second photocoupler (15) inactive, so that the electric signal by pressing the operation switch (8) on the local side is enabled only when the air conditioner (1-,) is in operation. , it is possible to process it as a stop signal in the CPU T21 and transmit it to the air conditioner (1-,) as a stop output, and by opening the changeover switch (17), the local operation switch (8 ) electrical signal is a driving signal.

Both the stop signal becomes invalid, and conversely, only the operation signal can be made invalid by the closing operation.

As is clear from the above explanation, the first and second photo couplers (15), third photo couplers (16), and changeover switch (17) are used to switch between the central control switch (5) and the central/each room control switch (6). When the central control switch (5) is activated by one operation and deactivated by the other operation, the processing device (2) converts the electric signal of the local operation switch (8) that corresponds to the operation signal to the central control switch (5). 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-
, ), When (6-0) is closed, both the second transistor (22) and the second photocoupler (15) are inactive, and the individual operation switch (4-1) or the local operation switch (8) is inactivated. When you press , if the air conditioner (1-,) is stopped, it will generate a running signal and the air conditioner (l-+) will operate; on the other hand, if it is running, it will generate a stop signal and the air conditioner H=
) stops.

In this case, it is stopped and the switch for each room (6-0) is pressed.
is closed, the all-room start switch (4-0) is closed, and the ring counter (13) is activated.
Furthermore, the operation signal is transmitted to each air conditioner (1-, ) to (1-
n), but for air conditioners that are already in operation, the first transistor (21
) does not emit output, so
A driving signal is issued only when the vehicle is stopped.

In addition, the ring counter (13) has a large number of air conditioners (1-,
) to (1-n), the control board section (12-,
) to (12n) in order.

On the other hand, when all or a majority of the air conditioners (1-,) to (1-n) are operating, if the collective room switch (6-0) is closed, the all room stop switch (4-, ), the first transistor (21) and first photocoupler (14) corresponding to the air conditioners in operation are activated, allowing a stop signal to be issued and the air conditioners to be stopped all at once.

Next, switch any switch (5) of the central management switch (5).
-, ), (5-0), the second transistor (22) operates, and when the selector switch (17) is opened, the second photocoupler (15) operates the second transistor (22). ), the individual operation switch (4-1) can be used to start/stop the operation, the all-room start switch (4-) can be used to operate all stopped items at once, and the all-room stop switch (4-,) can be used to start or stop the operation. It is possible to stop the contents all at once, but the operation switch on the hand side of the air conditioner (
In the operation 8), the transmission is restricted by the restriction means (18).

Therefore, operation is performed only on the centralized controller (3) side.
Stop is operational.

For those with the changeover switch (17) closed, the second photocoupler (15) is inactive when the air conditioner is operating and activated when the air conditioner is stopped, so the operation switch (8) on the local side is Even if you press , the signal corresponding to the stop signal will be valid and the signal corresponding to the operation signal will be invalid.
Only the stop operation is possible.

In this way, the operation of the air conditioner can be easily divided into priority management by the central controller (3) and concurrent management by the central controller (3) and each room.

(Effects of the Invention) As is clear from the above explanation, the present invention allows air conditioners to be started and stopped in parallel from either the central control side or from the local side of each room, and also from the local side. It is possible for the central control side to give priority to starting and stopping control, and it is possible to perform centralized control on the central control side and individual stoppages in each room in parallel. It can be used to control operation on both sides, and therefore air conditioning operation in hospitals, hotels, dormitories, etc. can be managed rationally, quickly, and smoothly.

In particular, when priority is given to centralized control, modulation operation can be stopped in each room on the user side, which has the advantage of avoiding unnecessary operations and achieving high economic efficiency.
