Expanded ammeter

Abstract

The invention relates to an expanded ammeter which comprises the components of AC line parameter detecting equipment, temperature difference detecting equipment, air amount detecting equipment and a sunplus SPCE061A processor. The sunplus SPCE061A processor is connected with the AC line parameter detecting equipment, the temperature difference detecting equipment and the air amount detecting equipment. and is used for determining electric energy which is supplied by an AC line based on output of the AC line parameter detecting equipment and determining whether a staircase door-and-window is opened based on the output of the temperature difference detecting equipment and the air amount detecting equipment. Through the expanded ammeter, the function of the ammeter can be expanded and detecting precision of the ammeter to the electric energy which is output by the AC line can be improved.

Description

technical field [0001] The invention relates to the field of door and window monitoring, in particular to an extended fire meter. Background technique [0002] The detection of the opening and closing status of doors and windows in the stairwell is very important. For example, when children or the elderly are waiting for the elevator alone in the stairwell, if the doors and windows originally used for ventilation in the stairwell are kept open to the maximum state at this time, it is easy to cause children or the elderly to wait for the elevator. A vicious event of the elderly falling, or, when the temperature difference between the stairwell and the outside is too large, and the air volume in the stairwell is too large, if the residents waiting for the elevator in the stairwell are weak or the patients who have just been discharged from the hospital, it is easy to cause the residents to catch cold , colds, and strokes in severe cases have adversely affected the lives of res...

[0002] The detection of the opening and closing status of doors and windows in the stairwell is very important. For example, when children or the elderly are waiting for the elevator alone in the stairwell, if the doors and windows originally used for ventilation in the stairwell are kept open to the maximum state at this time, it is easy to cause children or the elderly to wait for the elevator. A vicious event of the elderly falling, or, when the temperature difference between the stairwell and the outside is too large, and the air volume in the stairwell is too large, if the residents waiting for the elevator in the stairwell are weak or the patients who have just been discharged from the hospital, it is easy to cause the residents to catch cold , colds, and strokes in severe cases, which have a negative impact on the lives of residents in the buildings where the stairwells are located

[0003] At present, the detection of the switch status of the doors and windows in the stairwell generally adopts the method of independently setting up a set of detection equipment in the stairwell. Although this method can achieve the detection effect, if such a set of equipment is installed in each stairwell, it will take up Plenty of stairwell communal space, which was otherwise limited

At the same time, the detection accuracy of the existing stairwell fire meters is not high, and there is still room for improvement in the structure and performance of the measurement
