Conventional configuration and its problems Conventionally, in a centralized management system, when individual air conditioners are remotely controlled to shut down and their status monitored by a central control device, each individual air conditioner is controlled to shut down only by the central control device. Air conditioners can be controlled individually at the location where they are installed, or only when the air conditioner is in a state where it can be operated by a central control device, using a power switch or operation switch installed on the air conditioner. In this type of configuration, the central control device and the air conditioner side can freely control the operation and shutdown of each other, but one of them takes priority, which poses a problem in terms of operability.

Purpose of the Invention The present invention solves the problems of conventional operability and allows individual air conditioners to be stopped and operated at their installation locations, as well as to be able to perform stoppage control and air conditioner operations from a central control device. It is possible to monitor the status (operating or stopped), and the operation of the air conditioner is performed either from the air conditioner side or from the central control device, whichever is later operated. In addition, if the control signal from the central control device is affected by noise in the transmission path, or if the timing between the operation on the air conditioner side and the operation from the central control device is sensitive, it will be possible to prevent mischief. Furthermore, after the compressor stops due to a momentary power outage to the air conditioner, the compressor is not restarted immediately when the power is turned on again. The purpose of the present invention is to provide a terminal device for central control of air conditioners that prevents malfunctions and maintains the safety of the aircraft.

In the control pulse generation circuit 31 of the terminal device 6, the logical relationships among the illustrated signals M, C, T, A, B, P, and R are as follows.

A=TC+TC s=ytc+ytで P=ABR また信号Tは制御信号Cが変化した後の論理レベルと逆

A=TC+TC s=ytc+yt and P=ABR Furthermore, the signal T is reversed for a predetermined period of time from the logic level opposite to the logic level after the control signal C changes. A=i when changing from stop to operation or from stop to operation.

また信号Bは、制御信号C及び状態信号Mの論理レベル

Therefore, the control pulse P output from the control pulse generation circuit 31 will be different from the signal A=1 unless the reset circuit 38 generates the 7-bit signal, that is, when the signal R=1.
This will occur when B=1. In the end, the control pulse P
occurs within a predetermined time from the time when the control signal C changes, and only when the control signal C and the state signal M do not match.

This means that even if the control signal C changes from stop to run while the room air conditioner is operating, or even if the control signal C changes from run to stop while the room air conditioner is stopped, no malfunction will occur. Furthermore, by setting the time for generating the control pulse C to be within a predetermined time, the remote control switch 5
If the operation stop switch 6 provided in the control unit is manually operated, the same operation will occur, and no contradiction will occur in the control logic.

In this way, when the room air conditioner is stopped and an operation command is issued by manual operation or automatic operation of the control operation switch 1θ of the central control device 7, a control pulse P is generated and the operation is stopped. The circuit 19 gives a signal to the terminal 1 similar to when the stop switch 6 is manually operated.

The microconbeater 12 detects this signal, shifts to a driving operation, and lights up the driving display lamp 7 by a scanning operation. Due to this lighting operation, the state detection circuit 22 detects the operating state and issues a state signal M. At the same time, the control valve P is turned off, and the status signal M is transmitted to the central control device 7 via the status signal output circuit 26, and the status display lamp 11 is turned on, so that the status monitoring 2 display can be performed.

Conversely, if a command to stop the room air conditioner is issued from the central control device 7 while it is in operation, the stopping operation will be performed in substantially the same manner as described above.

Note that when the room air conditioner is started or stopped by the operation stop switch 6 of the remote control switch 6, the status signal M is sent to the central control device 7, and the central control device 7 controls the control (a1 times signal) accordingly. The control pulse generation circuit 31 is configured to immediately change the control signal C so that it has the same logic as the state signal M, so that it can immediately respond to the next control operation. Since the signal C and the status signal C have the same logic, no control pulse P is generated and stable control is achieved.

The reset circuit 38 is activated especially when the room air conditioner is operating.
In addition, when a momentary power outage occurs while the compressor 2 is in operation, the compressor 2 stops, and when the power is re-energized, a control parnu P occurs due to a discrepancy with the reset operation in the central control device 7, etc.
In order to prevent the compressor 2 from being turned on too soon and causing damage, generation of the control pulse P is prohibited especially when the power is re-energized. After the reset signal R of the reset circuit 38 is turned off, the operations described above are performed.

Effects of the Invention As mentioned above, the air conditioner central management terminal device of the present invention has the following features:
An operation stop operation circuit having a switch means that is electrically connected in parallel to a non-locking operation stop switch provided in a part of the air conditioner, a state detection circuit that detects the operation and stop state of the air conditioner, and The status signal output circuit that outputs the status signal to the central management device and the control signal input circuit that inputs the control signal for stopping operation from the central management device are connected to each other within a predetermined time from the time when the control signal changes, and There is a control pulse generation circuit that generates a control pulse only when the logic of the status signal and the status signal do not match, and outputs it to the operation stop operation circuit, and a control pulse generation circuit that generates a control pulse and outputs it to the operation stop operation circuit, and a reset signal that generates a reset signal for a certain period of time when the power to the air conditioner is momentarily interrupted or after it is reenergized. It is composed of a reset circuit that prohibits the generation of control pulses in the control pulse generation circuit, and allows air conditioners to be stopped individually at their installation locations, and can also be controlled from a central control device, as well as for status monitoring and control. Since the operation of the air conditioner can be performed from either the air conditioner side or the central control device, the operability is greatly improved, and control signals are controlled by the state. Signal is in the specified state (logical mismatch)
The operation stop operation is enabled only when the control signal is affected by noise in the transmission line, or the operation on the air conditioner side and the operation from the central control device are delicate. Even if it is done at the right time, the air conditioner will not be stopped inadvertently, and the reset circuit will prevent the compressor from starting immediately when the power supply to the air conditioner recovers from a momentary power outage. This has the effect of making the machine operate stably and safely.
