If these conditions occur, the production will be directly affected and even an accident of boiler explosion may occur. Traditional boiler supervision is carried out by manual work in real time, but manpower resources are wasted. Some boilers are provided with automatic alarm devices at present, but if a supervisory person is far away from the boiler, the supervisory person is difficult to perceive when an alarm occurs, and accidents still can be caused; in the prior patent CN202141032U, an automatic alarm device for a boiler is disclosed, wherein an alarm and the boiler are not located in the same area, and the alarm can be pulled to any one of remote positions, such as a supervision room of a supervision person, a personnel office area and the like, through a lead. Therefore, when the alarm works, the supervisory personnel can find out the position of the boiler in time and deal with the abnormality at the first time, but the operation still needs manual operation by the staff, the degree of automation is not high, and certain safety risk still exists.
