Expansion type energy meter

Abstract

The invention relates to an expansion type energy meter which includes an AC line parameter detection device, a temperature difference detection device, an air quantity detection device and a sunplus SPCE061A processor. The sunplus SPCE061A processor is in separate connection to the AC line parameter detection device, the temperature difference detection device and the air quantity detection device, and is intended for determining the electricity provided by an AC line on the basis of the AC line parameter detection device, and is also intended for determining whether the doors and windows in the staircase are opened on the basis on the output of the temperature difference detection device and the air quantity detection device. According to the invention, the expansion type energy meter can expand functions of energy meters and increase precision in detecting electricity output by the AC line.

Description

[0001] This invention is a divisional application of a patent with the application number 2016101848375, the application date is March 28, 2016, and the invention name is "extended fire meter". technical field [0002] The invention relates to the field of door and window monitoring, in particular to an extended fire meter. Background technique [0003] 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 ...

[0003] 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

[0004] 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
