Boiler control device and method by detecting malfunction of each control valve {Boiler Control device and Method about by Wrong Operation Detection of Each Room Control Valve}

The present invention relates to a boiler control apparatus and a method thereof by detecting malfunction of each valve for controlling the room, and more particularly, a main remote controller capable of controlling the whole of one boiler and several sub-remote controllers capable of controlling the heating temperature of each room. In the heating system provided, it is invented to improve the stability of the system by displaying whether or not it is correctly opened or closed every time the valve for controlling the heating pipe of each room.

Recently, a heating system has been developed and widely used for heating a plurality of rooms using a single boiler. Such a boiler is a multi-remote control device, and a main remote control can display a heating operation and a setting including a setting. A number of sub-remote controllers installed outside the kitchen or other rooms can be displayed including the operation and setting for heating.The main control unit in the boiler and the sub-remote controller in each room are provided between the heating pipe of each room and the heating water outlet of the boiler body. Opening and closing of several installed valves, and each chamber control unit for transmitting and receiving a state between the remote control is configured.

Therefore, the user can turn on / off and set the temperature of the entire heating through the main remote control, and the sub-remote control of each room can arbitrarily control the heating in the corresponding room while the main remote control is kept on. Can be set and controlled on / off.

However, such a heating system in the related art has a problem in that it is not known whether the valve connected between the boiler main body and the heating pipe of each room to control the circulation of the heating water is actually opened or closed.

That is, in the conventional heating system, the control unit of each room outputs an on signal to the valve of the corresponding room and operates the boiler unconditionally, so that the valve does not open despite the output of the on signal due to the valve sticking. There is a problem that the boiler is overheated because the heating water is not circulated.

The present invention has been made in order to solve such a conventional problem, it is determined whether the opening and closing each time the valve for the heating pipe control valves in each room, whether or not the correct opening and closing, if the valve is not opened or closed due to a failure to display an error and At the same time, it is an object of the present invention to provide a boiler control apparatus and a method thereof by detecting malfunctions of the valves for controlling each room, which can stop the operation of the boiler and ensure the stability of the system due to the boiler boiling.

The above object of the present invention is to provide an opening / closing detection sensor in the valve itself and a valve state detection unit and an error state display unit in each chamber control unit. When the valve is turned on, it checks whether the corresponding valve is opened correctly. If it is not opened, it displays an error and shuts off the boiler at all, and if it is recognized as open, the boiler is operated to maintain the heating tapping temperature at the desired heating set temperature. This can be achieved by turning off the valve when the off signal is input from the sub-remote control unit in the room and detecting the off state again, if it is not closed, displaying an error and stopping the boiler operation.

Therefore, despite the opening of the valves for the control of heating piping in each room, it is not possible to prevent boiling due to the non-circulation of the heating water due to seizure, etc., as well as the user to confirm whether the valve is broken with the naked eye. You can get the service quickly.

Outputting and waiting if the corresponding valve is correctly closed.

Referring to the effect of the present invention made of such a configuration and steps as follows.

First, when a user inputs various key signals according to a heating operation through the operation instruction input unit 11 of the main remote controller 1, the signal is displayed on the main display unit 13 through the first central processing unit 12 and at the same time, 1 is transmitted to the main control unit 2 and each room control unit 3 via the transmission and reception unit 14 to control the operation and opening and closing of the boiler and the valve.

At this time, the main display unit 13 of the main remote controller 1, the on / off state, the set temperature and the tapping temperature of the boiler transmitted through each room control unit 3 and the main control unit 2 as well as the user key input signal described above. And the like.

In addition, the second and third transceivers 21 and 22 of the main controller 2 smoothly perform data communication with the main remote controller 1 and each room controller 3, and the tapping temperature detector 23 The second central processing unit detects the tapping temperature of the heating water input through the temperature sensor, not shown, and performs all control functions according to the boiler starting and stopping by executing a predetermined program using various data inputted from each part ( In the electric appliance driving unit 25 under the control of 24), the electric appliances such as burners, three-way valves, and pumps, which are electric appliances for starting and stopping the boiler, are directly controlled.

In addition, the fourth and fifth transmitting and receiving units 31 and 32 in each room control unit 3 facilitate data communication with the main control unit 2 and each room sub-remote controller 4, and input from each unit. The output of the third central processing unit 34 is performed by the valve driving unit 33 under the control of the third central processing unit 34 which generates a predetermined control signal according to the result after executing a predetermined program using various data. In response to the signal to perform the opening and closing function of the valve (7) installed between the boiler body and the heating pipe (5) of each room.

At this time, each chamber heating water circulation control valve (7) is provided with a driving motor as well as an operating state detection sensor 71, the output of the operating state detection sensor 71 is the valve state detection unit 36 in each chamber control unit (3) It is input to the third central processing unit 34 to determine whether the valve 7 is correctly opened or closed.

Meanwhile, the third central processing unit 34 in the chamber control unit 3 receives the output signal of the valve state detection unit 36 and determines whether the corresponding valve 7 which outputs the previous open / close signal is correctly opened or closed. The result is displayed on the valve error status display unit 35 and the sub display unit 43 of the corresponding sub remote control unit 4, so that the user can display the valve error status display unit 35 and the sub remote control unit 4 of the chamber control unit 3. By checking the message appearing on the sub display unit 43, it is possible to recognize whether it is in an error state or correctly opened or closed.

When the user inputs various key signals according to the heating operation of the corresponding room through the operation instruction input unit 41 of the sub-remote controller 4 installed in each room, the signal is transmitted to the sub display unit through the fourth central processing unit 42. At the same time as shown in (43) and is transmitted to each chamber control unit 3 and the main control unit 2 through the sixth transmission and reception unit 44 is to control the operation and opening and closing of the boiler and valve.

At this time, the sub display unit 43 of the sub remote controller 4 displays the on / off state of the boiler, the set temperature of each room, the room temperature, the on / off state of the valve, and the timer operation.

On the other hand, the second central processing unit 24 in the main control unit 2 receives the output signal of each room sub-remote control unit 4 through the respective room control unit 3 to detect whether the boiler "on" signal is input to any one of them. Thus, if any one of the boiler on-signal is input, the third central processing unit 34 in each chamber control unit 3 outputs the "on" signal to the corresponding valve through the valve drive unit 33.

As described above, in the third central processing unit 34 in the chamber control unit 3 which outputs the ON signal to the valve as described above, the valve state detecting unit 36 connected to the operation state detecting sensor 71 of the valve 7 is provided. It is determined whether the valve is correctly opened by receiving the output signal of.

In this case, the operation state detection sensor 71 may present a micro switch or a proximity switch.

If it is determined that the third central processing unit 34 in the chamber control unit 3 does not open despite outputting the "on" signal to the valve, an error state is recognized and the valve error state display unit 35 in the chamber control unit 3 is detected. ) And an error message is output to the sub display unit 43 of the corresponding sub-remote controller 4 and the boiler is not driven, so the user can immediately recognize that the valve is broken and request after-sales service through checking the error message. It is.

In addition, since the boiler itself is not operated at the time of failure of the valve 7, it is possible to prevent the occurrence of boiling due to the operation of the boiler even though the heating water is not circulated.

On the other hand, if the valve is correctly opened as determined by the third central processing unit 34 in the chamber control unit 3, the second central processing unit 34 in the main control unit 2 normally ignites the burner through the electronic device driving unit 25. After the boiler is operated, the heating set temperature set by the user and the tapping temperature of the heating water detected by the tapping temperature detecting unit 23 are compared with each other, and the burner is turned on / off to control the heating temperature. Combustion and fire extinguishing are repeated to reach.

In addition, while the boiler is operating as described above, the main control unit 2 continuously receives the output signals of the main remote controller 1 and the sub-remote control unit 4 in each room to generate an “off” signal for closing the valve of the chamber. It keeps detecting whether it is input.

As a result of the detection, when the off signal for the valve of the chamber is input, the third central processing unit 34 in the chamber control unit 3 outputs an “off” signal for closing the valve through the valve driving unit 33. As described above, it is determined whether the corresponding valve is correctly closed by receiving the output signal of the valve state detector 36.

As a result, if the valve is not closed despite the output of the " off " signal to the valve, an error occurs in the valve error status display unit 35 in the chamber control unit 3 and the sub display unit 43 of the sub remote controller 4 as described above. If the valve outputs a message and waits for the valve to be correctly closed, the user confirms that the valve has failed by checking the error message displayed on the valve error status display unit 35 and the sub display unit 43 of the corresponding sub remote controller 4. You can immediately recognize and request after-sales service.

As described above, according to the present invention, the user can immediately recognize that the valve of the room is broken by quickly determining whether or not the valve is correctly opened or closed every time the control unit of each room opens or closes the valve for controlling the heating pipe of each room. After-sales service, etc. can be requested within the time, and since the boiler itself does not operate in the event of a valve failure, it is possible to prevent the boiling caused by the non-circulation of the heating water during the boiler operation, thereby ensuring the stability of the system. It is a very useful invention.
