Description

[0001] The present invention relates to a locking method for a room controller,

[0001] The present invention relates to a method of locking a room-lock key of each control system, and more particularly, to a method of locking a room-lock key in a room where a central control for heating is required such as an inn, In the case of non-occupied households (vacant rooms), the manager can control only the central office, etc. In order to prevent the tenant from manipulating the room control of each room, a personal computer (PC) It is.

Generally, a boiler is used to heat water by using combustion heat and heat generated by burning it using fuel, coal or gas as fuel, or supplying electricity to a heater, and supplying hot water to various heating facilities In the case of a domestic boiler, hot water is supplied to the piping installed on the floor of the room or the like, and is used for supplying hot water through a water pipe or the like.

On the other hand, an energy-saving automatic heating system that separately adjusts the room temperature of each room by installing a separate room conditioner in each room in a building with several rooms, such as an inn, a hotel room, and a one-room, Control system.

In such a cubic control system, when the room is not required to be heated, the valve is automatically closed to prevent waste of unnecessary energy and reduce the fuel cost.

In this way, the heating of each room can be controlled by a heating control program installed in a personal computer at a remote place such as an office or the like where a central heating control is required, such as an inn, a study room,

Accordingly, it is possible to monitor the heating condition of each room and to control the heating ON / OFF or the room temperature, if necessary, so that it is possible to control the heating remotely conveniently without visiting each room, thereby reducing unnecessary heating.

However, since the conventional control heating system can be controlled not only in the office but also in each room, it is practically possible to use the heating according to the tenant's intention. In particular, in the case of an inn, Can not be collected, so unnecessary heating can cause an excessive heating cost.

Accordingly, in order to solve such a problem as described above, Korean Patent Registration No. 10-0433449 discloses a " multifunctional temperature control system for energy saving and a control method thereof ", which discloses an indoor temperature controller And a main computer of the central control room to control the room temperature, the method comprising the steps of: a) determining the indoor convection temperature, the heating water temperature, and the ondol structure temperature by a convection temperature sensor, a heating water temperature sensor, Measuring the temperature to generate respective analog signals; b) converting an analog signal generated in the step a) into a digital signal by an A / D converter; c) Detecting the pivoting state of the locking device by means of a sensor mounted on the locking device of the door, judging the locking device to be vacant when it is rotated in the locking direction by the key inserted in the locking device and rotating it in the direction of opening the locking device A step of judging as a rearmament; d) If it is determined in step c), the minimum value of the temperature values converted in step b) is compared with the set temperature value inputted by the user, and when the former is smaller than the latter, the heating operation signal is generated, A heating operation signal is generated when the heating water temperature is equal to or lower than the lowest reference temperature previously programmed, and when the heating water temperature is lower than the lowest reference temperature Generating a heating stop signal if the heating stop signal is exceeded; e) displaying the measured temperature value, the set temperature value and the operating state of the heating device; And f) returning to step a) after a predetermined time interval has elapsed.

In this way, centralized multifunctional temperature control in apartments, dormitories, hotels, condominiums, and other communal buildings can reduce energy consumption to some extent compared to conventional heating control systems, Since the computer is connected directly, it is advantageous in that the facility is simplified compared to the existing information collecting unit and the gateway, and the wireless transmission / reception module between the room temperature controller and the power supply unit of the household appliances such as the air conditioner, When the user leaves the room, the power of the household appliances is cut off due to the power shutdown signal and the gas shutoff signal of the room temperature controller, so that the user can save power and waste gas leakage.

However, such a centralized room temperature control method is a method in which a room controller installed in an arbitrary room to be controlled by an administrator among temperature controllers (hereinafter, referred to as "room controllers" There is not provided any function that can prevent the person who is forcibly obstructed or resides in the room from controlling the heating temperature and the like, so that there is a problem that the heating cost reduction through the method of reducing the unnecessary heating can not be performed.
