The remote control system of the room temperature controller according to the present invention includes a TRC unit 110; A mediation server 130; And a user terminal 140.

First, the indoor temperature controllers 10, 20, and 30 are not centralized cooling or heating units installed in the building, but they are individually installed in a room, for example, an air conditioner or a radiator, for example, an electric heater or a boiler. It will also be said that the combined air-conditioning and heating system equipped with a complex function is also included.

The room thermostats 10, 20 and 30 are used for a room temperature regulator 10, 20 and 30 without using a system reset or an internal system, the present invention implements a system for applying a control input signal using an infrared ray to a light receiving unit.

Therefore, these room thermostats 10, 20, 30 should not be operated purely mechanically but should be able to be controlled electrically and electronically by an external signal.

Preferable examples of the room temperature controllers 10, 20 and 30 may be i) an air conditioner for an air conditioner, ii) an electronic hot air conditioner for a heater, a boiler (electronically controllable), and the like.

The TRC unit 110 is provided in the room and is configured to communicate wired data with the mediation server 130 as a wired line and transmit a control signal to the room temperature controllers 10, 20, and 30 wirelessly.

As will be described later, the TRC unit 110 is preferably installed on a wall of a height of 1100 mm to 1800 mm from the bottom of the room.

However, when the TRC unit 110 is installed on the ceiling of a room, there is a difference from the above-mentioned height, and there may be an error in the information acquired by the TRC unit 110. In this case, A certain compensation function for the acquired information may be added.

In addition, the TRC unit 110 must transmit a control signal to the room temperature controllers 10, 20 and 30 by radio. Most commercial products of the room temperature controllers 10, 20 and 30 are remote control via infrared . Remote control through the infrared communication requires the remote controller and the room temperature controllers 10, 20 and 30 to be located on the line of sight. The TRC unit 110 is connected to the room temperature controllers 10, 20 and 30 ) And a place where they can see each other without obstacles.

In FIG. 1, the TRC unit 110 is shown as one unit. However, it is needless to say that a separate TRC unit 110 may be provided for each of the individual heaters and the individual coolers, thereby operating independently.

The mediation server 130 is configured to perform data communication with the TRC unit 110 and can network with the TRC unit 110 using a conventional wired Internet method.

The user terminal 140 directly communicates with the intermediary server 130 and data communication with the TRC unit 110 is enabled using the intermediary server 130. [

1, the user terminal 140 may be implemented as a smart phone, a tablet PC, or a notebook computer.

The user terminal 140 can remotely monitor and control a user, that is, a person living in the room or using the room, the individual air conditioner or the air conditioner, i.e., the indoor temperature controller 10, 20, It becomes a means.

The user terminal 140 transmits a control signal to the TRC unit 110 and can acquire predetermined information from the TRC unit 110. This process can be implemented through the intermediary server 130. [

The TRC unit 110 of the present invention includes a power control unit (not shown); An operation selection unit (not shown); A monitoring unit (not shown); And an air volume control unit (not shown).

First, the power control unit generates a signal to turn on or turn off the power of the room temperature controllers 10, 20, and 30.

A conventional air conditioner, a boiler, a hot air fan, and the like can turn on or off the power through a remote controller. The power controller sends the turn-on or turn-off signal to turn on or turn on the room thermostats 10, 20, To turn it off.

The operation selection unit is useful when the indoor temperature controller (10, 20, 30) is a combined cooling / heating unit. In the case of the combined cooling / heating unit, the operation selecting unit can select a cooling mode or a heating mode with a remote controller And the cooling mode and the heating mode are selectable among the products under consideration. In this case, the operation selection unit utilizes the function of selecting the operation mode of the remote controller as it is. However, it is needless to say that a control signal for selecting the operation mode corresponding to the cooling / heating multifunctional apparatus is suitably adjusted. The user terminal 140 can select the operation mode of the air conditioner / multifunction peripheral through the operation selecting unit of the TRC unit 110 at a remote place.

The monitoring unit acquires information on the operation state of the indoor temperature controllers (10, 20, 30).

The operating state indicates whether the current room temperature controllers 10, 20 and 30 are in operation, the set temperature when the vehicle is in operation, whether it is the current cooling mode or the heating mode.

The monitoring unit indirectly determines whether the indoor temperature controller 10, 20, 30 actually receives the command in a certain operation mode or receives the set temperature information, And the like.

Information on the operation state acquired by the monitoring unit can be read by the user terminal 140 and the user can monitor the operation states of the individual room temperature controllers 10, 20 and 30 on the user terminal 140.

The air flow rate control unit measures the air flow rate emitted from the room temperature regulators 10, 20 and 30. Specifically, the air flow rate control unit includes an apparatus for measuring the air flow rate, for example, a pan, a motor, The air volume can be directly measured and the air volume set in the room temperature regulator 10, 20, 30 can be indirectly acquired similarly to the manner in which the monitoring section acquires information on the operating state. For example, if the TRC unit 110 controls to select the air volume of the room temperature controllers 10, 20 and 30 as 'strong', 'medium', or 'weak' to 'strong', the air volume controller controls the indoor temperature controller 10 , 20, and 30) are estimated to be strong (without direct measurement).

The air flow rate control unit finally transmits this information to the user terminal 140. The user terminal 140 controls the air flow rate of the room temperature controllers 10, 20 and 30 as 'air flow rate', 'medium air flow rate' '.

Also, the TRC unit 110 directly receives the signal for controlling the air volume of the room temperature controllers 10, 20, and 30 in the air volume control unit as well as controlling the air volume of the air conditioner by the remote controller. However, it is needless to say that the control signal must be matched to the product being marketed as described above.

The TRC unit 110 includes a temperature sensor unit (not shown); And a temperature control unit (not shown).

The temperature sensor unit is provided inside and outside the TRC unit 110 to measure the temperature of the room.

Since the TRC unit 110 senses the temperature of the room through the temperature sensor unit, the position of the TRC unit 110 is important as described above.

The TRC unit 110 is located at a position where the temperature is changed due to the wind to be blown rather than at a position where the TRC unit 110 is directly exposed to the wind of the room thermostats 10, It would be desirable to measure the indoor temperature.

The TRC unit 110 may acquire the information about the room temperature via the data communication between the external temperature sensor unit and the TRC unit 110 while the temperature sensor unit is provided outside the TRC unit 110. However, And there is a fear that the interior of the room may be damaged.

The temperature control unit acquires information on the temperature of the room from the temperature sensor unit, and then controls the room temperature controllers (10, 20, 30) such that the room temperature corresponds to the set temperature.

The target temperature set by the temperature control unit is received from the outside through the user terminal 140 as shown in FIG. 2. Then, as shown in FIG. 3, the current temperature B acquired by the temperature sensor unit The user A compares the set temperature A received from the user terminal 140 with each other and controls the room temperature controllers 10, 20 and 30 such as an air conditioner so that the current temperature B is lowered to the set temperature A As shown in FIG.

Of course, a series of processes for this operation inherently receives an instruction (RS-485 command (D)) from the user terminal 140, so that the remote controller E, that is, the TRC unit 110, And finally controls the operation of the room temperature controllers 10, 20, and 30 remotely.

The remote control system of the room temperature controller according to the present invention may further include an APC unit (automated power control unit)

The APC unit 120 is configured to be coupled to the plug of the room temperature regulator 10, 20, 30 and to be provided to an outlet in the room at the same time.

The APC unit 120 means an electronic outlet that is electronically controllable beyond a timer outlet (a receptacle with a time setting function), which is generally commercially available.

The APC unit 120 does not merely function to electronically disconnect the connection between the outlet and the plug but also controls the power supplied to the room thermostats 10, 20 and 30 via the plug, It is desirable to have a function of

 To this end, the APC unit 120 may include a power control reception unit 121. [

The power supply control receiving unit 121 receives a control signal by the TRC unit 110 wirelessly and is capable of interrupting power flowing into the room temperature controllers 10, 20 and 30, It corresponds to a kind of switching function.

In addition, as described above, the APC unit 120 may further include a power measurement unit (not shown), which corresponds to a kind of power meter included in the APC unit 120, And can be transmitted to the TRC unit 110.

The power measurement unit measures the power flowing into the plug of the room thermostats 10, 20 and 30 and transmits information about the power flowing into the TRC unit 110, that is, the measured power consumption information.

In this case, the TRC unit 110 checks the operating states of the room temperature controllers 10, 20, and 30 through the monitoring unit. If the room temperature controllers 10, 20, and 30 are not operated 20, and 30 to prevent the power from flowing into the room temperature regulator 10, 20, and 30, the power shutdown signal is sent to the power control control unit 121, Power is cut off from the source.

The TRC unit 110 of the remote control system of the room temperature controller according to the present invention may further include a motion detection sensor (not shown).

When the operation is not detected in the room, the TRC unit 110 checks the operation state of the indoor temperature controllers 10, 20 and 30 through the monitoring unit, When the room temperature controllers 10, 20 and 30 are not operated, the power shutoff signal is transmitted to the power control reception unit 121 so that power is not supplied to the room temperature controllers 10, 20 and 30, The standby power that the regulators 10, 20, and 30 can consume is cut off.
