[0012] The multifunctional adjustment controller of the smart bed can be configured with one or several health care accessories logic control modules according to the needs. The health care accessories logic control module is a complete 32-bit single-chip microcomputer control system. The module is connected to the host module through the CAN bus.

These conditions are mainly time period, body position, body temperature, respiration, heartbeat, muscle strength, working status, magnetic stimulation intensity, infrared thermal therapy temperature, air pressure, speed and other parameters. The multifunctional adjustment controller of the smart bed detects the above conditions and parameters and implements the automatic operation mode.

[0014] In particular, the multifunctional adjustment controller of the smart bed monitors and extracts the dynamic response physiological parameters of the patient's breathing, heartbeat, weight, habitual posture, muscle strength, etc. under the stimulation of health care accessories in real time, and evaluates the health care effect based on parameter prediction, providing feedback signals for closed-loop health care stimulation; online or offline detected physiological parameter trend data and offline expert mode and parameter adjustment data are continuously imported and improved into the cloud and machine-side "expert knowledge base" to guide model optimization, and use machine learning and artificial intelligence technology to establish a regulation model of stimulus-response relationship, automatically generate health care models characterized by expert "health care prescriptions" and "posture prescriptions", formulate different health care goals and task orientations at different health care stages, and continuously and cyclically implement model optimization and knowledge base optimization through big data acquisition and improvement of the "expert knowledge base" rule set to complete intelligent regulation.

[0015] In particular, the health care accessories logic control module effectively solves the problem of functional integration between smart beds and various health care accessories, and between various health care accessories, to meet the health care needs of bedridden people.

The extended function board on each bus node exchanges and shares information with the host through the CAN bus network, and processes and realizes specific functions independently, completing the functional integration and assembly of the system, and realizing the various functions of each unit of the "functional group" with high speed, high efficiency and high reliability.

[0032] like Figure 1 As shown, the main module of the multi-function adjustment controller also includes working status display and parameter display. In view of the different degrees of control function impairment that may exist in patients, the multi-function adjustment controller is equipped with optional mobile phone control, touch screen, voice, gesture and brain-computer interaction devices in addition to a key-operated wired or wireless hand operator to meet the control needs of different health care users.

[0033] Preferably, the communication function connection of the host realizes mobile and management terminal device management, user management, and remote expert management based on the cloud platform and cloud services, and utilizes technical means such as information reporting, database, expert system with learning ability, public account, etc. to realize functions such as information storage, sharing, remote control, expert intervention, and artificial intelligence intervention.

[0034] like Figure 1The neuro-regulated magnetic stimulation health care accessories shown are the basic configuration of the intelligent adjustment controller host system of the smart bed. The neuro-regulated magnetic stimulation health care accessories highly integrate the cutting-edge health care technology with the smart bed. The system's hardware, software and basic functions of the smart bed strongly support the implementation and improvement of the neuro-regulated magnetic stimulation health care function. Figure 6 The principle of the magnetic generator is described as follows: the main controller intelligently triggers the switches of the basic waveform generator of the magnetic stimulation device according to the preset magnetic stimulation health care auxiliary mode, operating parameters or "health care prescription", and completes the formation and output of the basic wave with adjustable voltage amplitude and adjustable trigger time through the control of the charging and discharging process of the capacitor; the device is equipped with optional background wave and sine wave waveform generation circuits, and the main controller can programmatically select the input of background wave or sine wave to enrich the combination of health care means and improve the health care efficacy. The magnetic generator and its positioning drive drive multiple electronic switches through the input and output ports of the host system to complete the waveform and composite waveform formation, and realize the precise positioning of the magnetic stimulation coil by driving the electric actuator and driving the airbag; like Figure 2 The input end of the basic function control and feedback module of the smart bed is connected to the motor drive address coding output and various position and posture sensors, and its output end is respectively connected to the electric actuator driver. The basic function control and feedback module of the smart bed is composed of several basic function submodules. The submodules are constructed according to the functional requirements of the smart bed to achieve the target action of the electric actuator. The submodules are independently installed on specific electric actuators to drive and complete specific target actions to achieve the posture change of the smart bed. The submodules include functions such as electric actuator drive address coding, electric actuator bidirectional driving, drive current detection, position, angle detection, etc., wherein the drive address coding defines the physical address of the electric actuator installed at different positions of the smart bed, which is used for the ID definition of CAN bus transmission; the bidirectional drive realizes forward and reverse rotation and stop control according to the instruction requirements of the ID on the CAN bus; the module detects the drive current and the status of position components such as variable resistors, encoders, and position switches, matches the main control instructions with the actual operating status of the electric actuator, and reports all the above information to the main controller in real time through the CAN bus to realize the functions of fault diagnosis, instruction interlocking, action programming, etc.

[0035] In particular, Figure 5The basic function control and feedback module configuration of the smart bed and the processing of weighing sensor signals with weighing function are described; the multifunctional adjustment controller of the smart bed is equipped with multiple ADC interfaces, and the signals of four weighing sensors are separately connected to the ADC interfaces and the data is fused and processed. Therefore, in addition to the weighing function to complete the weight and weight trend detection function, the multifunctional adjustment controller also provides weight information to guide proportional drug administration and dialysis rate calculation, and makes time-based records of water loss, blood loss, vomiting, excretion, etc.; the device judges the "irritability" and "anxiety" level and sleep state, bad sleeping habits of the bedridden person through the combination of the presence / absence of the four sensor signals, the weight sensor signals of the bilateral, head and feet, the continuous changes in body position such as supine, left side and right side, the number of turning over, and the state of leaving the bed, and automatically generates a "body position prescription". The smart bed automatically adjusts the bed posture at regular intervals to correct the bad sleeping posture of long-term bedridden people and avoid and reduce their harm from diseases such as respiratory disorders and bedsores.

[0036] The multifunctional adjustment controller of the smart bed receives and processes echoes based on millimeter waves and containing information on human physiological parameters such as breathing, heartbeat, and pulse through the serial port, thereby completing the collection of physiological parameters such as breathing, heartbeat, and pulse; the ADC interface of the multifunctional adjustment controller receives the value and status of force sensors installed on the feet and hands to complete the detection of muscle strength and muscle strength change trends, receives signals from various sensors, scales and processes the signals, and instantly obtains the human physiological parameters and changes in physiological parameters of the health care recipients, forming a closed-loop feedback system for health care information. The physiological parameters obtained online or offline are transmitted, stored, queried using database technology, and displayed in the form of continuous historical trend curves, lists, etc.

[0037] In particular, the trend data of physiological parameters detected online or offline and the mode and parameter adjustment data of offline experts continuously improve and enrich the "expert knowledge base" on the cloud and machine side to guide model optimization, and use machine learning and artificial intelligence technology to establish a regulatory model of stimulus-response relationship, automatically generate health care models characterized by expert "health care prescriptions" and "posture prescriptions", formulate different health care goals and task orientations at different health care stages, and continuously and cyclically implement model optimization and knowledge base optimization through big data acquisition and improvement of the "expert knowledge base" rule set to complete the intelligent regulation of smart beds.

[0038] like Figure 3The input end of the health care auxiliary logic control module is respectively connected to the output end of the operation status, position switch, timer, counter, etc. of each health care auxiliary to read the operation parameters and working status of the device. The output end of the health care auxiliary logic control module is connected to the input end of the actuator of the controlled infrared heat therapy, massage, squeezing, motor function recovery training, etc. The output end of the health care auxiliary logic control module is connected to the start and stop control end and the drive end of the health care auxiliary to control it. The working mode, counter, timer, angle amplitude parameter, current, temperature and other parameters of each health care auxiliary part are preset by the main controller through the human-computer interaction device, and are sent to the health care auxiliary part logic control module through the CAN bus to meet the health care program's needs for bed posture, target positioning, movement angle amplitude, stimulation intensity, number of times and duration and other health care plans; the position switch, angle amplitude detection device, current, temperature and other signals of the health care auxiliary parts are connected to the input end of the function board to monitor the working status of the device in real time, and the function board obtains and transmits the above parameters to the host. The host system compares the real-time parameters, system presets and stored target parameters, and implements target control of the smart bed and health care auxiliary parts. When the relevant parameters exceed the safety limit, multi-level alarms are issued to the health care personnel and equipment while providing safety protection, and the judgment and processing of the fault process are achieved without human intervention.

[0039] Figure 4 The main flow chart of the intelligent adjustment controller software of the smart bed is described. The intelligent adjustment control software of the smart bed configures the initial parameters of each interface module according to the function, establishes the operation tasks and command mailbox and status mailbox of each module, and completes the initialization of the intelligent adjustment control software of the smart bed; the human-machine interface task realizes the interaction of mobile phones, touch screens, remote controls, voice, gestures or brain-computer interfaces, and sends the corresponding commands to the command mailbox, and periodically refreshes the status information of the display mailbox; the data transmission task connects to the remote server, accepts remote commands and reports status information, creates and improves the "expert knowledge base" on the cloud and local machine side; the CAN communication task packages and sends commands containing the ID of each functional module according to the command mailbox, and receives the status information containing the ID of each module on the bus to update the status mailbox; schedules and runs the magnetic generator and starts single-target or peripheral multi-target positioning.
