Abstract

PURPOSE:To enable a selective operation control to be carried out in compliance with an air conditioning within a room for a plurality of air conditioners connected in one system under a remote controlling device by a method wherein either a control starting signal or a control stopping signal is sent by the remote controlling device. CONSTITUTION:A machine No. is set in advance by an address switch 8 stored in each of air conditioners 1 to 16. A control part 7 for each of the air conditioners 1 to 16 may judge in response to a control signal from the remote controllers 2 whether the machine No. is an odd number of an even number. An operation control specified by a control signal is carried out without any relation to an operating condition of each of the air conditioners 1 to 16 for every group of odd even number of the machine No. With such an arrangement, it is possible to perform an effective unitary control over a plurality of air conditioners 1 to 16.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an air conditioner control device, and more particularly to an air conditioner control device that centrally controls a plurality of air conditioners using a single remote control device.

(Prior Art) Conventionally, when operating multiple split-type air conditioners remotely, there have been two methods: starting or stopping multiple air conditioners connected to one remote control device all at once, or controlling each air conditioner individually using a remote control device. A method is used in which a program is generated and registered in the control unit of the air conditioner, and the operation of each air conditioner is controlled by signals from a remote control device.

In the former case, devices that do or do not need to be operated must be started or stopped all at once, and the range of control is wide, making it impossible to perform control that corresponds to indoor air conditioning conditions.

For example, if you want to control the operation of four air conditioners during the day and one air conditioner at night, you will need a remote control device that controls all three units and one that controls one unit during the day. The method used was to operate four units using both remote control devices, and to operate one unit at night.

In the latter case, detailed control can be performed for each air conditioner, but it is necessary to enter or store a control program on the remote control device for each air conditioner each time the operation starts, and It required a lot of signal wiring to reach the air conditioner, making installation a complicated task, and it was not very practical in cases where there were many odd numbers.

[Problem to be solved by the invention]

The present invention has been made in view of the above-mentioned problems of the conventional technology.The present invention divides a plurality of air conditioners into odd or even groups with preset machine numbers, and operates each air conditioner using a single remote control device. An air conditioner that can control the operation of each group at the same time regardless of the condition?
The purpose is to provide 11 devices.

[Means for solving the problem] In order to achieve the above objective, each air conditioner is assigned a machine number, divided into groups of odd numbers and even numbers, and the above remote control device is used to control the air conditioners regardless of their operating status. Control was carried out simultaneously so that each group was in operation or stopped operation.

[Operation] According to the above configuration, a machine number is set in advance in each air conditioner using the built-in address switch, and based on a control signal from the remote control device, the control unit of each air conditioner reads the set machine number. The effect of multiple air conditioners is checked by checking whether the number is odd or even, and controlling the operation specified by the above control signal for each group of odd or even numbered aircraft numbers, regardless of the operating status of each air conditioner. It is possible to perform simultaneous control.

〔Example〕

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a remote control device of the present invention.
Air conditioners 1 having a plurality of independent control devices (in the example, 16 large units) are connected to one remote control device 2 by a signal line.

FIG. 2 is a detailed block diagram showing the connection state with the remote control device 2, taking one air conditioner l as an example. The remote control device 2 has an operation key switch 3 for inputting control information, and displays the input control information. The operation key switch 3 is provided with a zone switch 6 for controlling each group.

The air conditioner 1 (11) is provided with an indoor control section 7 that receives signals from the remote control device 2 and signals from the temperature sensor and controls the operation of the compressor and indoor blower. 4 bits (16 units)
When a machine number consisting of is set and a control signal is input from the remote control device 2, the indoor control section 7 calls and confirms the machine number set by the address switch 8 and performs operational control.

FIG. 3 is a flowchart showing the signal flow of the remote control device of the present invention, in which each air conditioner 1 is started or stopped all at once according to a preset unit number by a control signal from the remote control device 2. When the zone switch 6 is turned on and operation control is commanded, the remote control device 2 determines whether the control flag is turned on, and if it is turned on, generates a control JON signal. and sends it to the air conditioner 1, and sets the control flag to "off." When E is not turned on, a control j OFF signal is generated and sent to the air conditioner l, and the control flag is set to "r on."

In the air conditioner 1, check which group the machine number set by the address switch 8 belongs to (odd or even), and set the operation flag to "R on" if the number is odd, or "Off J" if the number is even. .

In this state, when the IIIIWON signal is received, if the operation flag is "on", the compressor continues to operate, and if it is "off", the compressor starts operating.

When the control OPP signal is received, the operation flag turns on.
If it is off, the compressor will stop operating, and if it is off, the compressor will remain stopped.

In this way, by alternately transmitting a control ON signal or a control OFF signal to the air conditioner 1 using the control flag from the remote control device 2, the operation flag is set according to the odd/even group of the machine number of each air conditioner 1. Accordingly, it is possible to alternately achieve an operating state or a stopped state for each odd-numbered or even-numbered group all at once.

In the above example, due to the capacity limit of the indoor control unit 7 of the air conditioner 1, grouping by machine number is limited to odd or even groups, and the operation is limited to starting or stopping the compressor. By expanding the capacity of the inner control unit 7, it is possible to not only individually start or stop the operation of each air conditioner l, but also control the air volume adjustment, the angle adjustment of the wind direction plate, etc. Can be done.

〔Effect of the invention〕

As described above, in the present invention, the operating state of each air conditioner can be adjusted by sending a signal to start control or stop control of a plurality of air conditioners wired into one system from the remote control device. It is possible to divide the machines into two groups according to the preset machine number regardless of the situation, and to alternately display operating or stopped states, and control operations can be performed selectively and simultaneously according to the indoor air conditioning conditions. .
