The present invention provides a control system and method of a vehicle-mounted air conditioner. The system comprises a signal detection device, a signal processing device, a control device and an executive device; the signal detection device is used for detecting physiological data of users and transmitting a physiological data signal to the signal processing device; the signal processing device is a vehicle-mounted entertainment system and used for receiving the physiological data signal, determining physiological status of the users, and transmitting a physiological status signal to the control device; the control device is a vehicle-mounted air conditioner controller and used for receiving the physiological status signal and calculating set values of air volume, temperature, air-out mode and air-intake mode of the vehicle-mounted air conditioner; and the executive device is a vehicle-mounted air conditioner adjusting part and used for adjusting part arrangement of the air conditioner according to the set values of the air volume, temperature, air-out mode and air-intake mode of the vehicle-mounted air conditioner. An in-car comfortable environment suitable for physical status is built for the users, the users are not required to manually participate in the adjusting process, operation of the users is reduced, attention of a driver is ensured, and intelligence of the automotive air conditioner is increased.

The present invention relates to a method for estimating the posture of a multi-person human body, which relates to the processing of a record carrier for recognizing graphics, and is a method for estimating the posture of a multi-person human body based on depth features. The deep feature human key point detection model uses a two-stage training method combining bottom-up and top-down methods to train the deep feature human key point detection model, and finally uses the two-stage trained deep feature human key point detection model to detect the human body key points, and remove redundant key points that do not belong to the target person through human body key point clustering processing, and then output the result of multi-person human body pose estimation, which overcomes the problem of existing multi-person human body pose estimation technology in the case of dense crowds , poor robustness to target human body occlusion interference, and low accuracy rate of human body key point detection.

The invention relates to an automatic alarm method of a domestic gas water heater. The method includes: a controller, a gas detector, a carbon monoxide concentration detection device and an infrared human body detection sensor are attached onto a main device of the domestic gas water heater, the controller is connected with the gas detector, the carbon monoxide concentration detection device and the infrared human body detection sensor and judges whether to perform gas alarm or not according to detection results of the gas detector, the carbon monoxide concentration detection device and the infrared human body detection sensor, and the main device comprises a shell, a burner, a water inlet pipe, a water outlet pipe, a draught flue and a heat exchanger. By the method, insufficiency of gas burning and gas concentration in indoor gas can be detected, gas alarm information is transmitted to residents timely to facilitate measure taking of the residents, potential safety hazards of gas explosion and carbon monoxide poisoning can be avoided, personal and property safety of people is guaranteed.

The invention discloses an educational resource transmission system based on big data. The system includes a book collection scheduling management module, an intelligent recommendation module, a user information picking module, a data comparison module, an interest time judgment module, an interference factor insertion module, and a content correlation module. Degree recommendation module, standard correction module, book wrinkle degree determination module, e-book transmission module, authority level online identification module, partial interface remote sharing module, e-book forwarding authority module, non-VPN channel sharing module, e-book chapter purchase module and authority The license authentication module, through the collection book scheduling management module, judges whether the book is in the ordinary library or the rare library, and at the same time judges whether the remaining number of books selected by the user is less than the preset number, and recommends similar books when the number of books selected by the user is small Books, through the interest degree time judgment module, judge the user's preference for the selected book, and recommend books to the user.

The gear-type random student number system used in English classrooms belongs to the technical field of teaching aids, and aims to solve the problem in the prior art that English teachers cannot randomly ask all students in the class fairly. The invention includes a motor, a driving gear, a driven gear, a light source, a glass plate and a plane mirror; the driving gear and the driven gear have different diameters, the driving gear and the driven gear mesh, and ten channels are evenly distributed on the circumference of the driving gear and the driven gear. There are glass sheets in the through holes, and the numbers 0-9 are written on the glass sheets in the ten through holes of the driving gear and the driven gear in turn. The two light sources are respectively connected to any through hole on the driving gear and the driven gear Any through hole on the gear corresponds to it; the drive motor drives the driving gear to run and stop, and the control system controls the light source to emit light beams. The light beams emitted by the two light sources shine on the glass plate in the corresponding through hole, and the glass is illuminated. The numbers on the board are reflected by a flat mirror.

The attention reminding system used in English classroom belongs to the technical field of teaching auxiliary equipment, and aims to solve the problems existing in the prior art that students are inattentive in class and cannot be quantified in normal grades. The attention reminding system for English classroom of the present invention comprises motor, housing, shaft coupling, threaded shaft, tapered roller bearing, polarization block, driver and control unit; Described motor is fixed on one end of housing, and described The threaded shaft passes through the casing, one end of the threaded shaft is connected to the output end of the motor through a coupling, and the other end is connected to the polarizing block, and the threaded shaft is in contact with the casing through a tapered roller bearing; the The control unit controls the driver to drive the motor to run or stop. The invention can solve the problem that the English teacher reminds the students who are inattentive and quantifies the number of reminders, so as to ensure the attention of the students in the English class, improve the English learning performance, and provide a basis for scoring the English class performance in normal times.
