Definitions

  • the present invention relates to an air conditioning system, and more particularly, to an air conditioning system, which can restrict the manipulation of a local controller controlling the operation of an air controller.
  • an air conditioner is controlled by a remote controller.
  • the remote controller has operation setting keys such as an operate/stop key, a temperature up/down key, etc. a user controls the operation of the air conditioner by the operation setting keys.
  • the present invention provides an air conditioning system according to claim 1. Preferrred embodiments are set out in the appended claims.
  • the local controller may have an input unit for inputting information restricting the manipulation of the local controller.
  • the local controller may perform a plurality of operation settings of the air conditioner, and information restricting at least one of the plurality of operation settings may be inputted into the input unit.
  • the input unit may include a plurality of input keys for performing the plurality of operating settings of the air conditioner, and information restricting the inputting of operation setting information by at least one of the plurality of keys may be inputted into the input unit.
  • the local controller may control a set value of one operating parameter within an operation setting range, and information for varying the operation setting range may be inputted into the input unit. At this time, at least one of the plurality of operation settings may be restricted by manipulating at least two of the plurality of input keys.
  • the input unit includes a plurality of input keys for performing the plurality of operation settings of the air conditioner and a function key. At least one of the plurality of operation settings may be restricted by manipulating at least one of the plurality of input keys and the function key. At this time, the plurality of input keys performs independent operation settings of the air conditioner, and when one of the plurality of input keys is manipulated before and after the manipulation of the function key or during the manipulation thereof, the inputting of information by the one input key may be restricted.
  • the local controller may include an operation manipulating unit for controlling the operation of the air conditioner; an authentication unit for performing user authentication; and a manipulation restriction unit for restricting the manipulation of the operation manipulating unit when the user authentication is confirmed.
  • the manipulation of the local controller may be restricted by the remote operation of the remote controller. Accordingly, it is possible to prevent a certain user from manipulating the operation settings of the air conditioner at his or her own will, thereby improving the operation characteristics of the air conditioner.
  • FIG. 1 is a block diagram illustrating the construction of an air conditioning system 100 in accordance with one embodiment of the present invention.
  • FIG. 2 is a schematic plane view of a local controller 110 as shown in FIG. 1 .
  • the air conditioning system 100 includes an air conditioner 140 and a local controller 110.
  • the air conditioner 140 includes an indoor unit 130 disposed in an indoor space and an outdoor unit 120 disposed in an outdoor space.
  • the indoor unit 130 and the outdoor unit 120 are communicatively connected to each other via a network 161.
  • the air conditioner 140 includes one outdoor unit 120 and one indoor unit 130, but the present invention is not limited thereto.
  • the air conditioner may include one outdoor unit and a plurality of indoor units, or may include a plurality of outdoor units and a plurality of indoor units.
  • the local controller 110 controls the operation of the air conditioner 140, and includes an operation control unit (not shown), an input unit 150, and a display unit 170.
  • the input unit 150 receives an input of user operation and manipulation information, and includes a plurality of input keys and function keys.
  • a user enters operation settings of the air conditioner 140 by using the input keys. For example, the user can increase or decrease a set temperature by using a first input key 151 and a second input key 152, and can set a ventilation mode by using a third input key 153. Further, the user can change an air flow 154 by using a fourth input key 154. Further, the user can start or finish the operation of the air conditioner 140 by using a fifth key 157.
  • the function keys are not used when operation settings are directly performed, but they are used when the setting of the local controller 110 is performed or operation settings are performed along with the input keys.
  • the user can access to a function setting mode by the first function key 155, and enter an input signal corresponding to up/down/left/right by the second function keys 156.
  • the display unit 170 displays operation information of the air conditioner 140, and has an LCD panel structure. If the user enters operation information by the input keys and the function keys, an operation control unit (not shown) controls the air conditioner 140 so as to correspond to the operation information, and outputs a signal corresponding to the operation information to the display unit 170.
  • Information restricting the manipulation of the local controller 110 may be inputted into the input unit 150.
  • the user can restrict at least one of a plurality of operation settings through the local controller 110 by entering a manipulate signal by the input unit 150. That is, by means of the manipulate signal entered by the user, the inputting of operation setting information by at least one of the input keys can be restricted. If the user sets to restrict the manipulation by the first input key 151 and the second input key 152, the user cannot enter a manipulate signal by the first input key 151 and the second input key 152, thereby making it impossible to decrease or increase a set temperature.
  • a method of restricting operation settings by the input keys and the function keys may be set in various ways.
  • the user can restrict the setting of a specific operation by manipulating at least two of the plurality of input keys. For example, if the user presses the first input key 151 and the third input key 153 at the same time, and then presses the first input key 151 again, the manipulation by the first input key 151 may be restricted. However, any one of the input keys is manipulated before and after the manipulation of a specific function key or during the manipulation thereof, the inputting of information by the input key may be set to be restricted. At this time, it is possible to set such that the manipulation of the input key may be restricted in the manipulation of pressing a function key for a long time.
  • the operation of a specific input key is disabled, thus disabling the setting of a specific operation by the specific input key.
  • a room temperature can be considered as a specific operation parameter of the air conditioner 140. If an operation setting range is inputted so as to be set to a lower limit temperature or an upper limit temperature, the user can start the air conditioner 140 only when the room temperature is lower than the lower limit temperature or higher than the upper limit temperature. That is, if the room temperature is within the range of a lower limit or an upper limit, it is impossible for the user to enter a manipulate signal by the fifth function key 157. Accordingly, the user can restrict unnecessary operation of the air conditioner 140 using the local controller 110 by performing the setting for changing the operation setting range.
  • the local controller 210 includes an operation manipulating unit 255, an authentication unit 280, and a manipulation restriction unit 290.
  • the operation manipulating unit 255 has a display unit 270, an operation control unit 256, and an input unit 250.
  • the structures and operations of the display unit 270, operation control unit 256, and input unit 250 are similar to those of the display unit 170, operation control unit (not shown), and input unit 150, so a detailed description thereof will be omitted.
  • the difference between the local controller 210 and the local controller 110 described above of FIG. 1 is that a separate authentication procedure is required for setting restrictions on the manipulation of the local controller 210.
  • the authentication unit 280 receives authentication information inputted from the input unit 250 and performs user authentication. If user authentication is confirmed, the manipulation restriction unit 290 receives an input of information restricting the manipulation of the operation manipulating unit 255 again, and restricts the manipulation of the operation manipulating unit 255.
  • the present invention is not limited thereto, and if user authentication is performed, the manipulation of the operation manipulating unit 255 may be restricted according to stored information. Details about restrictions on the manipulation of the operation manipulating unit 255 will be discussed with reference to the above description of the local controller.
  • the manipulation of the operation manipulating unit 255 is restricted only after a user performs authentication, there is an advantage that only a specific user can restrict the manipulation of the operation manipulating unit 255.
  • various authentication information can be used as user authentication information, and a password can be used.
  • the present invention is not limited thereto, and voice information, iris information, card key information and so on can be used.
  • FIG. 4 is a block diagram illustrating the construction of an air conditioning system 300 in accordance with still another embodiment of the present invention.

  • the remote controller 315 can vary the setting range of a specific operation parameter of the air conditioners 340. Thus, the user is allowed to select a set value of the specific operation parameter only within the above setting range by the local controllers 310.
  • the remote controller 314 can set the operation range of a specific operation parameter of the air conditioners 340. Hence, only when the specific operation parameter of the air conditioners 340 is beyond the above operation range, the user can perform operation and manipulation on the specific operation parameter by the local controllers 310. Also, if a specific operation parameter of the air conditioners 340 is within the above operation range, the remote controller 315 may make impossible the operation and manipulation of the local controllers 310. In other words, if the temperature of a room where the air conditioner 340 is installed is between a set lower limit temperature and a set upper limit temperature, the local controllers 310 is unable to start the air conditioners 340.
  • the local controllers 310 is able to start the air conditioners 340.
  • the remote controller 315 may set such that the manipulation of all of the local controllers 310 may be restricted, or such that the manipulation of some of the local controllers 310 may be restricted.
  • the local controllers 310 include input keys (not shown) having a physical structure
  • the input keys of the local controllers may have a touch panel structure.
