Research And Development Of Smart Bed Control System Based On WIFI

With the development of science and technology and the improvement of living standards,the concept of smart home system has gradually become familiar to many people.Many smart home products have reached tens of thousands of households.There is a wide range of applications and huge market demand.Many enterprises and manufacturers shift their R&D center of gravity focus to the field of smart home.Many products have been put on the market and brought great convenience to people's lives.All kinds of electrical appliances in the home environnment are moving toward the direction of intelligence,digitization and informatization.At the same time,some non-electrical devices that are closely related to people are also embedded in a circuit system so that they can be automatically controlled.Smart beds in the background of smart home have been in our country for more than ten years and can provide a better resting environment for people.However,the existing smart bed control system is complicated in integration into the home system,and the bedplate driving structure is complex,the design cost is high,resulting in low popularity.There are now a number of nursing-care bed systems available that have similar functions as smart bed systems but are generally used in hospitals or nursing homes where there is a need,and are controlled by wired buttons or by wireless remote control,Home system as a centralized control of multiple devices at home.Therefore,it is necessary to design a smart bed suitable for home use,which not only brings good sleep to people but also simplifies the driving structure and reduces the design cost.Based on the above problems,the subject around the smart bed system improvements,reference to the existing structure of the care bed,designed to integrate smart home system smart bed control system to simplify the smart bed control structure,while using wireless transmission function to push the motor Bed form of motion.Brushless DC motor PID control based on neural network to make the bed run smoothly.so that the smart bed in the home system can both help people better rest,but also have the nursing role,to develop a smart bed for home use.The smart bed control system that meets the requirement was designed,and the smart bed suitable used for home was developed.In this paper,starting from the design requirements of the smart bed,the structure of the bed and the control part of the motor are mainly described.The number of turns and speed of the four motors under the bed are put forward.Based on this,the hardware and software of the brushless DC motor control system Design.At the same time using WiFi technology to transmit data so that the control process can be carried out in a wireless network environment,the development of hand-held terminal software,to achieve a good human-computer interaction in order to achieve smart bed control.
