Description

    Technical Field
  • The present invention relates to a central control system, and more particularly to a central control system which restricts indoor unit control input from outside so that indoor units can be operated according to a schedule set by a central control unit.
    • Background Art
  • Recently, as the use of air conditioners has increased remarkably, the air conditioners tend to be installed in rooms in homes and offices in buildings.
  • Further, a manager can centrally control a plurality of outdoor units and a plurality of indoor units connected to outdoor units without approaching the outdoor units by separately installing a central control unit connected to the outdoor units for central control and constructing a central control system to the central control unit.
  • Then, the central control system controls the operations of the outdoor units and the indoor units through the central control unit and operates the indoor units according to control signals of a schedule of the indoor units by setting the schedule at the interval of an hour.
  • However, in the conventional central control system, since if an operation control signal is input from a control panel provided in the indoor unit or a remoter controller while the indoor unit is preforming the operation according to the schedule set by the central control unit, the input control signal is performed prior to the other signals, the operation state set by the schedule of the central control unit cannot be maintained.
  • Therefore, the schedule function of the central control unit on the indoor unit is weakened and the effectiveness of central control decreases.
  • Japanese patent document JP11006644 details an air conditioning control system which automatically controls air conditioning in such a manner that energy conservation is compatible with comfortableness by detecting the presence or absence of humans in each room and taking priority over the conditioning schedule of air conditioning.
    • Disclosure of Invention Technical Problem
  • Accordingly, the present invention has been developed in order to address the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a central control system which restricts a control signal received by indoor units and operates the indoor units according to setting of a schedule when a central control unit sets the schedule for controlling the operations of the indoor units.
  • Another object of the present invention is to provide a central control system which can reduce the power consumption and increase the effectiveness of central control by individually controlling indoor units with a central control unit.
    • Technical Solution
  • In order to accomplish these objects, there is provided a central control system as set out in claim 1.
  • Embodiments of the present invention provide an operation method of a central control system, which comprises the steps of: inputting an individual control signal to an indoor unit; deciding whether the performance of the input signal has been set; and determining whether the operation of the indoor unit according to the individual signal is to be performed according to the decision.
  • Embodiments of the present invention provide an operation method of a central control system, which comprises the steps of: operating an indoor unit by a central signal of an central control unit; inputting an individual signal to the indoor unit during the operation of the indoor unit; and controlling the operation of the indoor unit by selecting a central signal or an individual signal on the basis of whether the central signal comprises setting of the operation of the indoor unit according to the individual signal.
    • Advantageous Effects
  • According to the present invention, the indoor units can be individually controlled by restricting external signals input to the indoor units and controlling the indoor units so that the indoor unit can be operated by the signals input from the central control unit.
  • Further, since the indoor units can be individually controlled, unnecessary waste of power consumption can be prevented, the effectiveness of the central control of the central control unit can increase, and the function of the schedule can be reinforced.

  • The storage section 302 stores the individual information of the indoor unit 30 and the control signal received in the central control unit 10. Then, the control signal received in the central control unit 10 is an operation control signal of the indoor unit 30 or a control signal set by the schedule setting section 111.
  • Hereinafter, the operation of the present invention will be described.
  • FIG. 4 is a flow chart showing the operation method of the central control system according to the present invention.
  • Referring to FIG. 4, a control signal for controlling the operation of an indoor unit 30 is input to an indoor unit 30.(S10) Then, the control signal input to the indoor unit 30 includes a control signal input from a remote controller 40 of the indoor unit 30 and a control signal input from a control panel of the indoor unit 30. Hereinafter, the control signal inpout from the remote controller 40 of the indoor unit 30 and the control signal input from the control panel of the indoor unit 30 are referred to as "external signals".
  • After the external signal is input, a control section 301 of the indoor unit 10 determines whether a schedule control signal set by the central control unit 10 is received.(S11) Then, the schedule set by the central control unit 10 relates the operation control of the indoor unit 30 at the interval of an hour.
  • If there is not a received schedule control signal, the operation is performed according to an input external signal.
  • If the indoor unit 30 receives the schedule control signal, the control section 301 of the indoor unit 30 determines whether the schedule includes stop setting.(S12)
  • Then, if the schedule control signal includes stop setting, the indoor unit 30 interrupts the received external signal so that the indoor unti 30 cannot be operated according to the external signal.(S 14)
  • If the schedule control signal does not include stop setting, the indoor unit is operated according to the input external signal.(S13)
  • If the schedule control signal includes locking setting together with stop setting in the operation, the indoor unit 30 is operated only by the schedule set in the central control unit 10.
  • Then, in the case of locking setting, the indoor unit 30 maintains the current operation state and ignores the additionally input control signals.
  • Further, a simultaneous performance of stop setting and locking setting is referred to as permission setting. In the permission setting, since the input external signal is interrupted by the stop setting and the current operation state of the indoor unit is maintained by the locking setting, the indoor unit 30 is operated only by the schedule set in the central control unit 10.
  • As mentioned above, since the external signal input to the indoor unit is restricted and the indoor unit is controlled so as to be operated by the signal input from the central control unit, the indoor units can be individually controlled.
  • Further, since the indoor units can be individually controlled, unnecessary waste of power consumption can be prevented, the effectiveness of the central control of the central control unit increases, and the function of the schedule is reinforced.
    • Industrial Applicability
  • According to a central control system and an operation method of the central control system of the present invention, external signals input to indoor units are restricted. Further, since the indoor units can be controlled so as to be operated by signals input from a central control unit, the indoor unit can be individually controlled. Further, since the indoor units can be individually controlled so that unnecessary waste of power consumption can be prevented and the effectiveness of the central control of the central control unit can increase, the industrial applicability of the present invention is high.
