Abstract

PURPOSE:To permit the operation of an air-conditioning machine when the code of a magnetic card is read and the read code coincides with a preset code. CONSTITUTION:The code of a magnetic card 8 is read by a reading unit 11 to input it into a judging unit 13 and compare it with a code, read out of a memory unit 12 through a control unit 15. When the code coincides, a coincidence signal is outputted through an outputting unit 14 to transmit it to a main body control unit 2 through a signal line connected to a setting unit 5. The main body control unit 2 judges the coinciding signals and inputs a signal transmitted by the operation of an operation switch of the setting unit 5 and signals generated by the operation of respective setting switches whereby the operation of the air-conditioning machine is controlled under a set condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a magnetic card type air conditioner control system according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a conceptual diagram of the configuration of an embodiment of a control system for a magnetic card type air conditioner according to the present invention. In the figure,
Reference numeral 1 is an air conditioner body. A main body control unit 2 controls the operation of the air conditioner main body 1 and the like. A remote control unit 3 is connected to the main body control unit 2 by a transmission line 4 for transmitting control signals and the like. Reference numeral 5 denotes a setting unit, which includes an operation switch 6 and other operation changeover switches (heating, air blowing, dry, cooling, etc.) not shown,
A room temperature setting switch, timer switching switch, time setting switch, etc. will be installed. A card signal output unit 7 reads a code recorded on the magnetic card 8 and outputs a required signal when the magnetic card 8 is inserted to a predetermined position in the direction of the arrow.

FIG. 2 is a block diagram of essential parts of an embodiment of a control system for a magnetic card type air conditioner according to the present invention.
In the figure, reference numerals 2, 5, 7 and 8 are the same as those in FIG. A reading unit 11 reads the code of the magnetic card 8. A memory unit 12 stores the set code.
A discriminating unit 13 inputs the code from the reading unit 11 and compares it with the code read from the memory unit 12 to make a discrimination. An output unit 14 sends a signal from the determination unit 13 to the main body control unit 2 via a signal line from the setting unit 5. A control unit 15 controls each unit of the card signal output unit 7.

Next, the operation of the control system for the magnetic card type air conditioner according to the present invention will be described with reference to the flowchart of FIG. When operating the air conditioner, first, the magnetic card 8 is inserted into the reading unit 11. The reading unit 11 inputs the code of the magnetic card 8 to the discrimination unit 13 via the reading control unit 15.
The determination unit 13 compares the code read from the memory unit 12 via the control unit 15 and makes a determination. Then, when a match is determined (step 1: Yes, hereinafter abbreviated as ST1 etc.), a signal of "match" is output via the output unit 14 (ST2). This signal is transmitted to the main body control unit 2 through the signal line from the setting unit 5, and the main body control unit 2 discriminates this "match" signal and switches to the standby state for remote control signal input from the setting unit 5 (ST3 ). Then, signals such as operation start / stop, operation switching, and room temperature setting are input from the setting unit 5, and the air conditioner is operation-controlled under each of the set conditions (ST4).

Further, when a magnetic card 8 having a different code is attached to the reading unit 11 or the magnetic card 8 is removed, a signal is not input from the reading unit 11 to the discriminating unit 13, so that the discrimination of the code is performed. Becomes impossible (ST1: No), the signal of “mismatch” is output (ST5). This signal is output 14
Is input to the main body control unit 2, and the main body control unit 2 stops the operation of the air conditioner (ST6). At the same time, the signal input from the setting unit 5 is stopped (ST7). As a result, the air conditioner 1 is in a state of not accepting the operation of the remote control unit 3.

FIG. 4 is a main part connection diagram of an example of the remote controller 3. In the figure, 21 to 28 are input / output terminals for control signals and the like, which are connected to the main body control section 2. S21 to S
24 is a switch for setting the operating conditions of the air conditioner. When the operation switch 6 is turned on, the terminal
The signal from 28 is output to terminal 23. Also, switch S21
And the like are, for example, temperature setting switches. Depending on which temperature scale this switch is set to, the signal from the terminal 25 is switched through S21 so as to be connected to one terminal or a plurality of terminals of the terminals 21 to 24, or not connected to any of them. As a result, the main body control unit 2 determines the setting condition of each switch depending on which terminal (21 to 24) outputs a signal from which terminal (25 to 28) and controls the operation of the air conditioner. To do. By the way, in the example of the drawing, the signal from the terminal 28 is only connected to any of the terminals 21 to 23 inside the setting unit 5, and is not connected to the terminal 24. Therefore, as the "match" and "mismatch" signals from the card signal output unit 7, for example, the signal from the terminal 28 is output to the terminal 24, or the output is stopped. Thereby, only the means for connecting the signal from the card signal output unit 7 to the setting unit 5 is provided, and no additional wiring is required between the remote control unit 3 and the main body control unit 2.

In the above description, an example of a wired remote control device has been described. However, even when the remote control device is a wireless remote control device,
If there is a vacant combination among any of the terminals 21 to 24 and any of the terminals 25 to 28, the remote control code corresponding to this combination is set and the remote control device is constructed. The same control as described above can be performed by additionally providing the code reading unit of the magnetic card.

[0012]

As described above, according to the control system of the magnetic card type air conditioner of the present invention, the code of the magnetic card is read by the reading unit (card reader),
The air conditioner can be operated only when a match is determined. Therefore, for example, if a magnetic card for the door lock of the entrance is also used, as long as the entrance door is locked, even if you go out without turning off the power of the air conditioner, the air conditioning will be performed in an unattended house. It is possible to prevent the problem that the machine continues to be useless. Further, since the signal from the reading unit is transmitted to the main body control unit of the air conditioner through the signal line from the remote control unit, it is not necessary to dispose a new signal line between the remote control unit and the main body control unit.
