Detailed Description

The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The invention relates to an intelligent dormitory monitoring device, which comprises an internal machine, an external machine and an external control module; the indoor unit is placed in a dormitory, the outdoor unit is placed outdoors, and the external controller is used for receiving signals and sending instructions;

the internal machine consumes little energy, and only part of the sensors consume electricity. Therefore, the starting state can be kept all the time, and the internal machine can be charged by using the common usb socket when charging is needed. When the button is pressed during use, the internal machine is in a monitoring mode all the time, when certain light intensity is detected at 12 o 'clock-6 o' clock at midnight, the voice assistant can remind students to sleep in time and not to stay up all the night, and when excessive sound is detected, the students can be reminded to stay quiet. For example, when the students go to sleep without lights or loud and loud at night and reach a threshold, the voice prompt function is triggered to remind the students to sleep early and form good work and rest habits. In daily life, when the concentration of harmful gas in the dormitory is detected to exceed the standard, the voice assistant can remind people to open the window and ventilate in time, and the internal environment of the dormitory is cleaned. If the hygiene condition in the dormitory is good, the word of 'excellent dormitory environment' is displayed on the display screen, and if a problem occurs, which part needs to be improved is displayed. When a fire occurs in the dormitory, the voice assistant can remind people to withdraw as soon as possible at the first time and send a buzzing alarm sound. All above information data can be transmitted for cell-phone APP by bluetooth module, and the mr head of a family can look over the very first time.

The signal transmission and control in the specific application are conventional functions and operations in the prior art, wherein the illumination sensor can directly convert received information into light intensity output, the light intensity output can be realized by setting a threshold value, a digital signal is output when the threshold value is exceeded, and a digital signal is output when the threshold value is not exceeded, wherein the digital signal is output when the threshold value is exceeded. The noise, peculiar smell and flame smoke sensors are similar in principle, and output decibel values of noise and indoor H₂And the S concentration and the smoke dust particle concentration are output to a digital signal through an output threshold. Illumination of lightThe noise, peculiar smell and flame smoke sensors are connected in parallel, work independently and do not interfere with each other, and when the sensors detect abnormal signals, the abnormal signals are uniformly reported to the voice player and the display screen which are connected in series. When receiving the digital signal '1', the small voice assistant reminds students in time to improve the sanitary environment condition of the dormitory.

the outdoor system designed by the invention integrates the sensors for detecting precipitation, temperature and humidity inside, and can comprehensively detect data to give students a suggestion before going out, such as paying attention to sun protection, carrying umbrellas and the like. The data information can be transmitted to a display screen of an indoor system through a sensor, and can also be transmitted to a mobile phone, so that students can make corresponding preparations in time. Specifically, the raindrop sensor can directly output digital quantity to the bluetooth module, and the digital quantity is 1 in rainy days and 0 in sunny days. Temperature and humidity sensor can directly transmit information to indoor display screen through bluetooth module. The raindrop sensor and the temperature and humidity sensor are connected in parallel and then connected with the Bluetooth module in parallel to form an external machine circuit. The intelligent clothes hanger mainly utilizes modules such as a light sensor and a raindrop sensor to detect outdoor weather environment, infrared and stepping motors control screw rods to rotate, STM32F407VET6 is used as a main control chip to achieve the process of automatically collecting clothes in rainy days and automatically airing clothes in sunny days, a stretchable wooden box is fixed on the side face of a balcony to protect the clothes from being drenched, and meanwhile the clothes can be prevented from being blown down to the ground by gusty wind. And the mode of combining manual control and automatic control is adopted to meet the living demands of people to the greatest extent, and convenience is brought to people.

The frame body of the intelligent clothes rack comprises a box body, a clothes-horse and a scissor-fork type telescopic arm; the transmission module comprises a stepping motor and a screw rod; the clothes airing rod is composed of two straight rods which are arranged in parallel and are perpendicular to the wall surface, a sliding groove is formed in the lower end surface of the clothes airing rod along the length direction, the screw rod is arranged in the sliding groove, and the stepping motor drives the screw rod to rotate so as to drive the clothes airing rod to move axially; the box body comprises a back plate and two baffle plates, and the back plate is fixed on the wall surface and is positioned below the root part of the clothes airing rod; the two scissor type telescopic arms are respectively controlled by a steering engine, one end of each scissor type telescopic arm is respectively fixed on two sides of the back plate, and the other end of each scissor type telescopic arm is respectively fixed with the baffle; when the clothes are aired, the baffle is opened, the scissor-type telescopic arms shrink towards the back plate when the baffle is closed when rain needs to be stored, and the clothes are shielded through the baffle.
