DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a control system for a magnetic card type air conditioner according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a conceptual diagram of a configuration of an embodiment of a control system for a magnetic card type air conditioner according to the present invention. In the figure,
1 is an air conditioner main body. Reference numeral 2 denotes a main body control unit that controls the operation of the air conditioner main body 1 and the like. Reference numeral 3 denotes a remote controller, which is connected to the main body controller 2 via a transmission line 4 for transmitting control signals and the like. Reference numeral 5 denotes a setting unit, which includes an operation switch 6 (heating, ventilation, dry, cooling, etc.) (not shown) in addition to the operation switch 6;
The room temperature setting switch, timer changeover switch, time setting switch, etc. are installed internally. A code reading unit 7 reads a code recorded on the magnetic card 8 when the magnetic card 8 is inserted to a predetermined position in the direction of the arrow. 9
Is a switch unit, which operates and outputs a signal when the code read by the code reading unit 7 matches a required code.

FIG. 2 is a block diagram of a main part of an embodiment of a control system for a magnetic card type air conditioner according to the present invention.
In the figure, 11 of the main body control unit 2 is a control unit, and controls each unit of the main body control unit 2 based on a signal from the switch unit 9 based on a signal from the setting unit 5. Reference numeral 12 denotes a memory unit for storing respective operation data and the like corresponding to the setting items of the setting unit 5. Reference numeral 13 denotes a determination unit which receives a signal from the setting unit 5 via the control unit 11 and compares it with data read from the memory unit 12 via the control unit 11 to make a determination. An output unit 14 operates the air conditioner based on a signal from the determination unit 13. The reference numerals other than those described above are the same as those in FIG.

Next, the operation of the control system of 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 code reading section 7. The magnetic card 8 is, for example, one in which a magnetic recording area is divided into a plurality of sections, and magnetism is recorded in a plurality of sections set for each card. Further, inside the code reading section 7, magnetic pins are provided at locations corresponding to a plurality of sections of the magnetic card 8, respectively. When the magnetic card 8 is inserted to a predetermined position, the magnetic pins are repelled by the magnetism recorded on the magnetic card 8 and come off from the lock plates, respectively, and the biasing spring presses the slider. The micro switch 9 is operated by being pressed by the slider, and outputs an ON signal (Step 1: Yes, hereinafter abbreviated as ST1: Yes, etc.). As a result, the main controller 2 is switched to the function of waiting for input of a remote control signal via the controller 11 (ST2). When the operation switch 6 of the setting unit 5 is operated, this signal is input to the discrimination unit 13 via the control unit 11 and is compared with the data of “operation” read from the memory unit 12 via the control unit 11,
Determine the match. In addition, operation switching from the setting unit 5,
A signal based on the settings such as the room temperature setting is input to the determination unit 13 and compared with and determined by the operation data read from the memory unit 12 via the control unit 11. The signal from the determination unit 13 is input to the output unit 14 via the control unit 11 to operate the air conditioner (ST3).

When the magnetic card 8 is removed from the code reading section 7, the magnetic pins and the like provided in the code reading section 7 operate in the reverse manner, and the switch section 9 is turned off (ST1: ST1). No). The OFF signal from the switch unit 9 is input to the control unit 11, and the control unit 11 stops the function of the main body control unit 2. As a result, the operation of the air conditioner 1 via the output unit 14 is stopped (ST4), and the signal input from the setting unit 5 is stopped (ST5). Therefore, the air conditioner 1 does not accept any operation by the remote controller 2.

FIG. 4 is a main part connection diagram of an example of the remote controller 3. In the figure, reference numerals 21 to 28 denote input / output terminals for control signals and the like from the remote controller 3, respectively.
Connected to S21 to S24 are switches for setting the operation of the air conditioner. The other reference numerals are the same as those in FIG. The switch S21 is, for example, a temperature setting switch. Depending on which temperature scale this switch is set to, the signal from terminal 25 is S
The terminal 21 is connected to one or more of the terminals 21 to 24 via the terminal 21 or switched so as not to be connected to any of the terminals. Therefore, the determination unit 13 determines which terminal (21 to
It is possible to determine the setting of each switch by determining which terminal (25 to 28) is outputting a signal to 24). By the way, in the example of the figure, the terminal 28
The other signal is only connected to one of the terminals 21 to 23 inside the remote control unit 3, and is not connected to the terminal 24.
Therefore, the signal via the switch unit 9 is connected via the setting unit 5 so as to be connected to the terminals 28 and 24, and the determination unit 13
In the above, when the signal from the terminal 28 is output to the terminal 24, it is determined that the switch unit 9 is turned on.
Therefore, only the means for connecting the signal from the code reading unit 7 to the setting unit 5 is provided, and there is no need to add wiring 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.
If any of the combinations of any of the terminals 21 to 24 and any of the terminals 25 to 28 has a vacant combination, a remote control code corresponding to this combination is set and transmitted. The same control as described above can be performed by providing a magnetic card code reading unit in the apparatus. In the above description, the magnetic pin is directly operated by the magnetism recorded on the magnetic card.
A storage unit for storing a code corresponding to the magnetic card 8 ;
Provided a detection unit for detecting the presence or absence of air card code reader 7, as compared to the code read out from the storage unit a code read from the magnetic card 8, when there is a match, a magnetic card
The switch unit 9 may be operated when there is a.

[0012]

As described above, according to the magnetic card type air conditioner control system of the present invention, the air conditioner can be operated only when a required magnetic card is inserted into the code reading section. Becomes Therefore, for example, if the entrance door is also used as a magnetic card for door lock, as long as the entrance door is locked, even if the user goes out without turning off the power of the air conditioner, the air conditioning in the unmanned house can be performed. It is possible to prevent a problem that the machine keeps running unnecessarily.
