Description

TECHNICAL FIELD [0001] The present invention relates to a boiler combustion instruction control method,

The present invention relates to a boiler combustion instruction control method in a wireless cornering control system, and more particularly, to a central temperature controller that communicates with a boiler in a state where a boiler is burning by one or more temperature controllers (central / If the wireless communication with the cubic valve controller is periodically performed normally, the combustion request of the boiler is maintained. If the communication is not received from the cubic valve controller within the predetermined time, the central temperature controller requests the boiler to perform the forced fire extinguishing By displaying the communication error, it is possible to reduce unnecessary fuel consumption caused by continuing the combustion of the boiler in a state where the valve opening state and the closing state of each valve can not be known beyond communication between the central temperature controller and each valve controller , Boiler So that the reliability of the boiler itself and the reliability of the combustion control can be greatly improved.

Generally, a boiler is a boiler that uses oil, coal and gas as a fuel and burns it or uses heat of combustion and heat generated by supplying electricity to a heater to supply 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 the hot water is supplied to the hot water through a water pipe.

In recent years, a cubic control system capable of supplying heating and hot water to a plurality of rooms using a single boiler has been developed and widely used. Such a cubic control system is usually a main temperature controller directly connected to a boiler, And at least one temperature regulator as sub-temperature regulators for performing wired or wireless communication with the central temperature regulator. In addition, at least one or more temperature regulators are connected to the central temperature regulator, And an angle valve controller for controlling the valve.

At this time, the central temperature controller is configured to be able to set various functions such as heating and heating temperature and to display the result thereof, and one or more temperature controllers installed in other kitchens or other rooms are used for heating the indoor space So that it is possible to display the results of the operation and the setting of the operation.

Therefore, the user can control the heating and heating temperature of the entire room through the central temperature controller, and also can control the heating and the heating temperature of the corresponding room through each temperature controller.

However, in the conventional wireless angular control system, regardless of the state of the respective valve controllers (that is, irrespective of whether or not the angular valve controller normally receives the data or the like transmitted from the central temperature controller and normally controls the respective valves) The control unit adopts a control method that only instructs the opening or closing of each valve. Therefore, unnecessary fuel consumption can be caused by continuously decreasing the burning instruction to the boiler even when the valve control of each valve is abnormal or abnormal. There is a problem that boiling occurs in the boiler.

When the predetermined time t1 elapses (Yes in S5) in the state where the communication is not received from the cubic valve controller 4 and the central temperature controller issues a forced fire extinguishing request (S6) to the boiler, a communication error And displaying the state of the second display device.

After the forced fire extinguishment is requested to the boiler 1 and a communication error is displayed on the display unit (S6), the central temperature controller 2 counts the predetermined time t2, and at any time during the time t2, It is determined whether predetermined communication data is received from the valve controller 4 (S7)

If predetermined communication data is received from the cubic valve controller 4 before the predetermined time t2 elapses, the display of the communication error is canceled (S8) and the initial standby state is returned.

When the predetermined communication data is not received from the cubic valve controller 4 (No in S7) until the predetermined time t2 elapses, a forced fire extinguishing request is issued to the boiler 1 and a communication error state is displayed on the display unit (S6). ≪ / RTI >

At this time, the predetermined time t2 for displaying the forced fire extinguishing request to the boiler 1 and the communication error to the display unit after the predetermined time t1 for counting in the state in which communication is not being received from the cubic valve controller 4, Is set to be long.

The operation and effect of the boiler combustion instruction control method in the wireless oval control system of the present invention having the above steps will be described as follows.

1, the present invention includes a boiler 1 having a wired communication unit 11, a central temperature controller 2 having wired and wireless communication units 21 and 22 and an MCU 23, (4) having a plurality of room temperature controllers (3) having a controller (31), a wireless communication unit (41), a valve driving unit (42) and an MCU (43) The central temperature controller 2 periodically controls each valve controller 4 in the combustion control for a wireless remote control system having a plurality of drivers 5 for controlling the valves 6 in each room in response to a signal, And it is possible to carry out maintenance request or forced fire extinguishing of the boiler by judging whether or not it is normally performed through wireless communication.

At this time, the central temperature controller (2) performs wire communication with the boiler (1), performs wireless communication with each of the plurality of temperature controllers (3) and each valve controller (4) Control function.

That is, in the standby state S1 after the power supply voltage is supplied, the MCU 23 in the central temperature controller 2 can control the temperature of the central temperature controller 2, (S2) whether there is a heating request.

As a result of the continuous and periodic determination as to whether there is a heating request, if there is a heating request from any of the temperature controllers of the central and the outdoor temperature controllers (2) and (3), the central temperature controller (2) 4) to determine whether predetermined wireless communication data is received (S3).

As a result of the determination, when the central temperature controller 2 receives predetermined wireless communication data (e.g., respective valve status information) from the cubic valve controller 4, the cubic valve controller 4 is normally operated And the central temperature controller 2 transmits a heating combustion request signal to the boiler 1 through the wired line so that the user can heat the corresponding room desired to be heated (S4).

However, if it is determined in the central temperature controller 2 that the predetermined communication data is received from the respective valve controller 4, if the non-receiving state (No in S3) And the predetermined time t1 is counted through a timer (not shown) provided in the MCU 23 of the central temperature controller 2 (S5).

If the predetermined time t1 elapses in the state where the communication is not received from the cubic valve controller 4, the central temperature controller 2 determines that even if the user requests the heating for the specific room, Since the open state and the closed state of the respective valves are not known at all through the valve 4, the forced fire extinguishing request (S6) is made to the boiler 1.

Therefore, it is possible to reduce unnecessary fuel consumption caused by continuous combustion of the boiler in a state where communication abnormality occurs between the central temperature controller (2) and each valve controller (4), and to prevent boiling of the boiler completely So that the reliability of the boiler itself according to the merchantability and combustion control can be greatly improved.

According to the present invention, as described above, when the predetermined time t1 elapses (Yes in S5) in the state where the communication is not received from the cubic valve controller 4, the central temperature controller makes a forced fire extinguishing request (S6) to the boiler (Not shown) provided in the central temperature controller 2, it is possible to display a "communication error" state, so that even if the user himself / herself requests heating for the specific room, It is possible to accurately recognize the cause of whether or not the state is maintained and perform necessary measures such as a service request quickly.

In the present invention, since the central temperature controller 2 does not communicate with the cubic valve controller 4, the forced fire extinguishing is requested to the boiler 1 and a communication error is displayed on the display unit (S6) The central temperature controller 2 counts the predetermined time t2 to judge whether a temporary communication failure has occurred or is actually in a communication abnormal state due to an environment or the like and at any time during the time t2, (S7) whether or not predetermined communication data is received.

If the predetermined communication data is not received from the cubic valve controller 4 (No in S7) until the predetermined time t2 elapses as described above, the forced fire extinguishing is requested to the boiler 1 as described above The process returns to step S6 of displaying a communication error state on the display unit, and the subsequent steps are repeated.

However, if predetermined communication data is received from the cubic valve controller 4 before the predetermined time t2 elapses, the central temperature controller 2 receives the predetermined communication data from the cubic valve controller 4, It is determined that the normal communication has been performed again and the communication error indication on the display unit is immediately released (S8). Then, the initial standby state is returned to the initial state and any one of the temperature regulators (2) (S2) to continuously determine whether there is a request for heating in step S12.

Accordingly, it is possible to prevent unnecessary service requests, which may occur due to the forced fire extinguishing of the boiler despite temporary communication failure due to the surrounding environment, as well as waste of time and consumers' mistrust of the products.

At this time, it is determined that a communication abnormality has occurred between the central temperature controller 2 and each valve controller 4, and communication is not received from the respective valve controller 4 to reduce unnecessary fuel consumption and prevent boiling of the boiler A predetermined time t2 for indicating a forced fire extinguishing request to the boiler 1 and a communication error on the display unit and then counting is set longer than the predetermined time t1 counted by the boiler 1.

For example, the predetermined time t1 for counting in a state in which communication is not being performed is set to 1 to 3 seconds, and the predetermined time t2 for displaying the forced fire extinguishment request to the boiler 1 and the communication error on the display unit, Minute or ten-minute unit, it is possible to reduce unnecessary fuel consumption that may occur as the boiler continues heating combustion even when a communication error occurs between the central temperature controller 2 and each valve controller 4, It is possible to prevent the cost incurred due to the service request, the waste of time, and the distrust of the consumers of the product, even though the communication is normally smooth even if a temporary communication failure occurs.
