Door and window opening system based on pull-wire displacement sensor and its application method

Abstract

The invention discloses a door and window opening degree recording system based on a guyed displacement sensor, the system comprises a processor which is used for processing data and transmitting a signal, the guyed displacement sensor which is used for measuring displacement variation, a real-time clock module which is used for recording time, a memory module which is used for saving a measurement result, a display module which is used for displaying the measurement result, and a button module which is used for setting door and window type and mounting position information, the guyed displacement sensor, the real-time clock module, the memory module, the display module and the button module are connected with the processor, and door and window measurement modes which are suitable for flat-opening door and window, push-draw door and window and the like respectively are provided. The system is suitable for doors and windows in various structure types, the door and window opening degree can be calculated through setting the corresponding door and window type and mounting position information, so that the mounting independence and the applicability are improved.

Description

technical field [0001] The invention relates to an opening degree recording system, in particular to a door and window opening degree recording system and an application method thereof. Background technique [0002] Indoor air quality and building energy saving have been the focus and focus of the HVAC industry in recent years. As an important means of introducing fresh air, the act of opening and closing doors and windows can not only conveniently and autonomously adjust the indoor heat and humidity environment, but also dilute indoor personnel’s breathing during the metabolism process. It is an important way of polluting gas emitted by the skin or skin, but different openings of doors and windows have a significant impact on indoor ventilation, airflow organization, air quality and energy consumption of air conditioners. The purpose is to reasonably analyze the opening probability of doors and windows, which can be used for building energy consumption analysis, guiding ven...

[0002] Indoor air quality and building energy saving have been the focus and focus of the HVAC industry in recent years. As an important means of introducing fresh air, the act of opening and closing doors and windows can not only conveniently and autonomously adjust the indoor heat and humidity environment, but also dilute indoor personnel’s breathing during the metabolism process. It is an important way of polluting gas emitted by the skin or skin, but different openings of doors and windows have a significant impact on indoor ventilation, airflow organization, air quality and energy consumption of air conditioners. The purpose is to reasonably analyze the opening probability of doors and windows, which can be used for building energy consumption analysis, guiding ventilation design, and providing new research ideas for building energy conservation. The existing opening and closing behavior recording devices only record the opening and closing information of doors and windows. The behavior obeys the binomial distribution, or simply divides the door and window behavior into three situations: fully open, half open, and closed. In real life, indoor personnel will adjust the opening of doors and windows according to their physiological or psychological needs, not just a simple binomial Or three-stage behavior division, real-time recording of the opening distance of doors and windows is the key to the study of door and window opening and closing behaviors, and it is also an important parameter for the design and evaluation of natural ventilation. The accuracy of energy consumption analysis is of vital significance. The pull-wire displacement sensor is well developed and easy to install. Based on this, the present invention proposes a door and window opening recording device based on the pull-wire displacement sensor. Measurements are carried out under the trigger of temperature changes, and the measurement results are sent to the processor for data processing and storage
