Abstract

PURPOSE:To permit to effect delicate control by a method wherein a monitoring and controlling board, a printed plate, respective operation switches and indicating mode are provided at a position apart from perimeter zone. CONSTITUTION:When the operation switch is pushed upon room cooling or heating, electric power is sent from an input voltage 11 to the printed plate 13 through a transformer 12 and is outputted through a commutating circuit 14, three terminals positive output voltage stabilizing electric source circuit 17 and lead wire 35 to operate the air-conditioning machine of remote position. On the other hand, an operation lamp is lightened by the output of 24V of low-voltage input and output terinal 29 of the side of main body to indicate operation. Next, when abnormality is generated due to some reason, an abnormality lamp is lighted through lead wire 33 and a resistor 20. Thus, control from remote position as well as the delicate control may be effected.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a monitoring and control device for individual air conditioners.

Unprecedented configurations and their problems Traditionally, in air conditioning systems for buildings, individual air conditioners, in which small air conditioners are invested in each floor and each room, are becoming more common. Although the need for centralized control is increasing, many of these air conditioners are one-piece specifications that are compatible with each system, and the content is that the power supply on the air conditioner side is simply turned on and off.
The system only controls the individual air conditioners installed in the verimer zone of each room individually, and has the disadvantage that fine-grained control is not possible.

OBJECTS OF THE INVENTION The present invention takes into consideration the above-mentioned drawbacks of the prior art, and aims to provide an individual air conditioning/shore monitoring device that is versatile and capable of controlling wood grain.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a remote monitoring and control device located at a distance from the main body of an individual air conditioner, and a transformer connected to an input power source to this monitoring and control device. , a rectifier circuit for the output signal converted by this transformer, and a 3-terminal positive output voltage stabilization circuit. The display mode is set to 1ff, and remote operation and remote display are performed.
I'm trying to control and monitor things.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A practical example according to the present invention will be explained with reference to FIGS. 1 and 2.

Figure 1 (1) is applied from the individual air conditioner body
This is a display board for a monitoring control panel 2 provided for location, remote control, and a push-button stop switch 3, and a push-button outside air cooling switch 6 for cooling with outside air. The operation switch 6 is combined with the operation lamps 7 indicating the active and the down states. 9 is the main body priority lamp of the air conditioner, and 10 is the abnormality lamp. In this manner, the display board 1 is provided with each damage switch and indicator lamp.

To explain the circuit, 11 is input AC1o
oV input voltage, 12 a transformer for output voltage transformation connected to the cigarette input voltage, 13 a printed circuit board, and this printed circuit board 13 has a rectifier circuit 14 for output signals.
A three-terminal positive output voltage stabilizing power supply circuit 17 is connected via a smoothing capacitor 15 and a capacitor 16 for absorbing high-frequency noise to obtain a stabilized fixed output voltage from an unregulated DC input voltage. capacitor 1
8. It has a capacitor 19 for absorbing high frequency noise, a resistor 20 connected to the abnormal lamp 10, and a resistor 21 connected to the main body priority lamp 9.

In addition, the output terminals include an outside air cooling output terminal 22 for sending to the air conditioner main body, a stop output terminal 23,
Cooling/heating operation output terminal 24, also operation lamp output terminal 2
5. Same outside air cooling lamp output terminal 26, same main unit priority lamp output terminal 27, same abnormal lamp output terminal 28
, and output terminals 29.30, 31.32 are provided,
Lead wins 33.34, 35.36 through each switch 3
゜4.6, indicator lamps 5, 7, 9, 10. t>= and is connected to the low voltage input/output terminal 29.

In the above configuration, a case will be explained in which the monitoring control panel 2 side of the air conditioner operates.

If the operation switch 6 is turned off during cooling or heating,
When is pressed, the input voltage 11 is transmitted to the printed circuit board 13 via the transformer 12, passed through the rectifier circuit 14. is driving. On the other hand, the Unsan rung 7 lights up due to the 24V output from the two low voltage input/output terminals from the main body side, indicating operation.

Further, if the air conditioner in the verimeter zone is given priority to the main body operation, the main body priority lamp 9 is turned on by the resistor 21 via the lead wire 34 in the monitoring control panel 2 lj. Next, if an abnormality occurs in the equipment for some reason, the abnormality lamp 10 is turned on by the resistor 20 via the lead group (33).Next, when the outside air cooling switch 4 is turned on, the operation switch 6 is turned off and the heating/cooling switch is turned off. The operation is switched from the operation to the outside air cooling operation, and the output circuit becomes the same as when the above-mentioned operation switch 6 is pressed, and outside air cooling is performed, and the operation of the outside air cooling lamp 5 and the low voltage input/output terminals is stopped.

In addition, in this embodiment, the monitoring and control panel 2 is made of a combination of the display board 1 and the printed circuit board 13 in order to correspond to an air conditioner, but this also corresponds to a commercially available switch box based on the JIS standard. This monitoring and control device (1) can be used in common with commercially available switch boxes, and has a λ requirement.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a supervisory control device, that is, a supervisory control panel, at a remote location (from the perimeter zone), and connects the supervisory control panel to an input power source. a rectifier circuit for the output signal converted by the transformer; 3. A printed circuit board consisting of a positive output voltage stabilizing power supply circuit, etc., and each operation switch and display mode connected from this printed circuit board through each lead embroidery are provided, and remote control and remote display are possible. Since it is designed to do this, it is not only possible to simply control the air conditioner body 91j, but also to control it from a remote location.
iN] control is possible, and it is also effective in that it can be applied to commercially available general-purpose devices without the need for a special monitoring and control panel as in this embodiment.
