The present invention not only detects and diagnoses the operation and failure of the components of the boiler and various sensors, but also diagnoses and controls the main controller that automatically controls the components or other sensors of the boiler so that the boiler itself and the main controller itself can be diagnosed. In addition to faults, the system detects and displays circuit faults occurring between the boiler and the main controller, and allows the user or administrator at the remote site to check and diagnose the boiler status on the monitor of the management computer via the Internet. The present invention relates to a method for automatically diagnosing and inspecting a boiler and a device for preventing a danger in advance by enabling control.

In general, a boiler refers to a device made so that hot water generated by burning an appropriate fuel (heating kerosene, gas, electricity, etc.) can be used for heating or the like. In other words, a boiler is used for flame combustion gas and other hot gases. As a device for generating steam or hot water by heating the temperature of the hot water generated during combustion to provide a hot water supply function and to circulate the hot water to obtain a heating effect.

On the other hand, when describing the general combustion operation process of the boiler, the blower operates to supply the fresh air to discharge the residual gas in the communication, and then the high voltage generated in the ignition transformer sparks at the electrode anode points in the combustion chamber to generate embers. Then, the electric pump, the gas fuel valve and the oil fuel valve are operated to supply the fuel suitable for combustion to ignite. The flame detector detects the initial flame flame and proceeds normal combustion depending on whether the combustion continues.

The above-mentioned combustion, hot water heating, and heating functions are usually controlled by the main controller of the boiler main body. For the convenience of the user, a room cone which can control the operation of the boiler at a remote location is connected to the main controller in a wired manner and installed indoors. It is.

On the other hand, in the conventional boiler as described above, when a failure occurs due to abnormal operation, it is common to notify the user by lighting a failure indicator in the main controller and the room cone.

Such a conventional boiler has a sensor attached to various components, that is, a combustion device, a boiler body, and various control devices, and various sensors are connected to the main controller, and the main controller is adjusted by a predetermined value or connected to the room cone. By remote control.

However, the conventional boiler merely notifies the user about the phenomenon of inoperability, and specifically does not indicate which component or part has failed and is inoperable.

Specifically, for example, in the case of incombustible combustion that occurs frequently in the conventional boiler,

In case of no combustion, there can be various causes. Firstly, when fuel is not supplied, secondly, when the fuel pump is abnormal, thirdly, when the ignition transformer is not operated and combustion is not possible. If the valve is not operated, a fifth non-combustion message or an alarm is displayed, for example, when no voltage is applied from the main controller which operates and controls the components.

As described above, in case of conventional boilers, various failures and damages of various parts are not displayed in detail, and only a message or an alarm indicating a non-combustion is displayed. In the case of a user or a manager, a highly skilled person inspects various parts in order to find a specific part that has failed As it is possible to diagnose the correct failure after replacing or replacing, there is a problem in that it is difficult to accurately determine the abnormality of the boiler.

The inventors automatic diagnosis and inspection method and the apparatus of the present invention is invented to solve the above problems,

First of all, it is the purpose to make the diagnosis of the operation of various parts of the boiler itself or other sensors and the presence of failure accurate by each part or sensor to make it possible to recognize a specific part or a specific sensor that is broken or damaged even by unskilled workers.

In addition, malfunctions and failures of the main controller that controls various parts of the boiler and various sensors also display specific failures and damages so that even unskilled workers can recognize them.

In addition, by detecting and diagnosing a fault in a circuit occurring between the boiler and the main controller, the purpose of the present invention is to display and recognize a specific fault and damage area.

In addition, the boiler itself, the main controller itself, and the display of the failure and damage between the boiler and the main controller to the remote user or administrator to check and diagnose the status of the boiler on the monitor of the management computer via the Internet remote control It is an object of the present invention to prevent the risk in advance by enabling the.
