[0027] Embodiment 1

[0028] According to the embodiments of the present application, an embodiment of an electric bed is provided, and it should be noted that, Figure 1 is a structural block diagram of the electric bed according to the embodiments of the present application, as Figure 1 shown, the device comprises:

[0029] a target bed body 10, a target controller 20, wherein the target controller 20 is arranged inside the target bed body 10,

[0030] A target bed frame is arranged in the target bed body 10, and a target driving element is arranged in the target bed body 10. The target bed frame comprises a plurality of sub-area bed frames, and the target driving element comprises a plurality of sub-driving elements. The plurality of sub-area bed frames correspond one-to-one to the plurality of sub-driving elements, and the plurality of sub-driving elements are used to adjust the height of the corresponding sub-area bed frame.

[0031] The target controller 20 comprises a plurality of sub-controllers, and the plurality of sub-controllers are communicatively connected. The plurality of sub-controllers correspond one-to-one to the plurality of sub-driving elements, and the plurality of sub-controllers are used to control the corresponding sub-driving elements.

[0032] The plurality of sub-controllers are connected to the corresponding sub-driving elements, respectively.

[0033] Target bed body 10 refers to the physical body of the electric bed, including the bed frame, mattress and all related mechanical parts, with height adjustment function.

[0034] Target bed frame refers to the support structure of the bed, which is a frame structure that can be adjusted in height and is set inside the bed body. The target bed frame is designed as a sub-area adjustable structure to adapt to the needs of different areas or different parts of the user's body.

[0035] Sub-area bed frame divides the bed frame into multiple areas that can be independently adjusted in height, with each area corresponding to a sub-drive element to provide personalized support and adjustment for different areas.

[0036] Target drive element refers to the mechanical drive device in the electric bed for physically adjusting the height or inclination of the bed frame, such as an electric push rod. The target drive element can be divided into multiple sub-drive elements, each responsible for adjusting the height of a sub-area bed frame.

[0037] Sub-drive element is an independent drive device corresponding to a sub-area bed frame, used to control the lifting or tilting of the area bed frame.

[0038] Target controller 20 is the central control system of the electric bed, responsible for receiving user instructions and converting them into control signals, which are distributed to each sub-controller for execution.

[0039] Sub-controller is part of the target controller 20, each sub-controller is associated with a sub-drive element, responsible for analyzing the commands of the target controller 20 and controlling the corresponding sub-drive element. Sub-controllers are connected in communication to ensure fast transmission and execution of commands.

[0040] Communication connection can be through wireless networks such as Wi-Fi, Bluetooth, which provides greater flexibility for system deployment, especially in scenarios where the bed body position needs to be frequently changed. Network communication can implement more complex control logic, such as cloud-based remote control and monitoring, linkage between intelligent devices, and control through mobile applications or voice assistants. Wired cables can also be used for serial communication between sub-controllers, ensuring the stability and security of command transmission.

[0041] This application introduces a distributed sub-controller network and independently adjustable sub-area bed frame to solve the technical problems of complex bed body height adjustment and the need for area and controller pairing in the prior art.

[0042] Compared with the traditional electric bed, each sub-area bed frame in the utility model is directly associated with a sub-controller and a sub-driving element, without the need for an explicit pairing process. When using the remote controller or other control devices, the user can directly adjust the height of the specific area of the target bed body 10 without additional operations, simplifying the operation process. And the communication connection between each sub-controller and sub-driving element means that each sub-area bed frame is associated with a specific control unit in design, and the control system can automatically identify the user's adjustment instruction for a specific area and respond immediately without the need for manual selection or pairing.

[0043] By decomposing one main controller into multiple sub-controllers, the utility model creates a distributed control architecture. Each sub-controller is responsible for the adjustment of a sub-area bed frame, which not only simplifies the complexity of a single control unit, but also improves the response speed and reliability of the entire system, because even if one sub-controller has a problem, the adjustment function of other areas is still not affected. That is, the independent design of each sub-controller and sub-driving element makes maintenance and upgrading very simple. If a part fails, the corresponding sub-controller or sub-driving element can be easily located and replaced without affecting the normal operation of the entire bed body. This modular design also facilitates customization and functional expansion of the bed body.

[0044] The communication connection between sub-controllers allows data sharing and synchronization between parts of the bed body, which means that in some modes (such as synchronous mode), the bed body can be adjusted in height as a whole, while in other modes (such as independent mode), each area can be operated independently without interfering with other areas. This design enhances the intelligent functions of the bed body and the flexibility of the operation mode, while also improving the system's compatibility with different control devices, such as remote controllers, mobile phone applications or voice assistants, without the need for independent pairing or settings for each device.

[0045] As an optional embodiment, the plurality of sub-controllers correspond to serial communication interfaces connected by wired cables.

[0046] In this embodiment, the communication connection between multiple sub-controllers is explained.

[0047] Among them, the serial communication interface is one of the standard interfaces for serial data transmission between electronic devices. In the context of a smart bed, sub-controllers exchange data with other sub-controllers through serial communication interfaces to achieve command transmission and state synchronization.

[0048] Among them, it is explained that the wired cable connection refers to the use of physical wires or cables as medium connection to realize signal transmission. Compared with wireless communication, wired cable connection provides a more stable, less interference data transmission channel, especially suitable for communication scenarios that require high reliability and real-time performance.

[0049] In this step, it is explained that in the intelligent left and right bed operating system, the communication between multiple sub-controllers is realized through the serial communication interface they each have and using wired cables. This design ensures the stability and real-time performance of data transmission between sub-controllers, and even in complex environments or long-distance control, it can ensure accurate and error-free transmission and execution of control instructions.

[0050] Wired cable connection provides a physically direct communication channel, which is less likely to be disturbed by external interference compared with wireless communication, ensuring that the system can operate stably in any environment and is not affected by electromagnetic interference or signal attenuation. Serial communication has strong real-time performance, especially with the support of wired cables, it can realize fast data exchange, which is particularly important for bed body control scenarios that require immediate response, such as quickly adjusting the bed body posture in emergency situations.

[0051] As an optional embodiment, the plurality of sub-drive elements includes a first drive element and the rest of the drive elements, and the plurality of sub-controllers includes a first sub-controller and the rest of the sub-controllers. The first drive element is used to perform actions corresponding to target control instructions, which are instructions sent by the remote control device to the first sub-controller and used to control the first drive element. The rest of the drive elements are used to perform actions corresponding to cooperative control instructions, which are instructions sent by the first sub-controller to the corresponding rest of the sub-controllers through wired cables in the case of serial communication, and used to control the rest of the drive elements.

[0052] In this embodiment, the types of sub-drive elements and sub-controllers are explained.

[0053] Among them, the plurality of sub-drive elements are the actuators in the electric bed used to physically lift or tilt each independent area of the bed frame, including the first drive element and the other drive elements. Each sub-drive element is responsible for the action control of a sub-area bed frame.

[0054] Among them, the first drive element is directly responsive to the target control instructions issued by the first sub-controller, and performs actions directly operated by the user through the remote control device, such as adjusting the height of the bed head.

[0055] Wherein, the rest of the drive elements are involved, the rest of the drive elements are other drive elements in the electric bed except the first drive element, which responds to the cooperative control instructions issued by the respective sub-controllers, and performs tasks consistent with the overall bed body action, such as in the synchronous mode, ensuring the lifting action of each part of the bed body is consistent, or performing separate control.

[0056] Wherein, the first sub-controller is involved, which is the controller directly paired with the remote control device, responsible for receiving target control instructions and controlling the first drive element. At the same time, it is also responsible for transmitting cooperative control instructions to the rest of the sub-controllers through wired cables.

[0057] Wherein, the rest of the sub-controllers are involved, which receive the cooperative control instructions sent by the first sub-controller through wired cables, and control the corresponding rest of the drive elements to perform actions.

[0058] Wherein, the target control instructions and the cooperative control instructions are involved, the target control instructions are the instructions sent by the user to the first sub-controller through the remote control device, used to directly control the first drive element, to achieve immediate adjustment of the specific area bed frame. The cooperative control instructions are instructions sent by the first sub-controller to other sub-controllers (corresponding sub-controllers) through wired cables under the serial communication mechanism, so that the rest of the drive elements can work cooperatively with the first drive element, to achieve the synchronous adjustment of the bed body as a whole or the adjustment of part of the area.

[0059] Wherein, the serial communication is involved, which is a data transmission method that allows information exchange and instruction transmission between sub-controllers, ensuring the action coordination and consistency between multiple drive elements.

[0060] The above describes a cooperative control mechanism between drive elements and controllers in an electric bed. In the use of the electric bed, the target control instructions sent by the user through the remote control device are received by the first sub-controller and directly executed by the first drive element, such as adjusting the height of the bed head or the bed tail. At the same time, in order to realize the coordinated action of each part of the bed body (for example, synchronously raising the bed head and the bed tail), the first sub-controller will send cooperative control instructions to other sub-controllers through serial communication according to the received user instructions, to ensure that the actions of the rest of the drive elements are consistent with the first drive element, so as to realize the unified adjustment of the bed body or the adjustment of part of the bed body.

[0061] Through the arrangement, the user does not need to manually switch the control of each part of the bed body, and can easily complete the instant adjustment of the specific area of the bed body through the remote control device, while automatically coordinating when synchronous action is needed, thereby improving the convenience of operation and the user experience. Through serial communication and collaborative control instructions, it can be ensured that each part of the bed body moves in unison when performing synchronous adjustment, thereby avoiding the problem of uncoordinated movement of the bed body caused by improper pairing of the controller, and enhancing the smoothness and comfort of the lifting action of the bed body.

[0062] As an optional embodiment, the target control instruction includes a data packet, and the data packet includes a mode flag, a command assignment, and execution data; and / or the collaborative control instruction includes a data packet, and the data packet includes a mode flag, a command assignment, and execution data.

[0063] In this embodiment, the data packet carried by the target control instruction and the collaborative control instruction is described.

[0064] Here, the data packet refers to a group of information encapsulated for transmitting data on a network. The data packet here contains the necessary information of the control instruction, which is used for the sub-controller to understand and execute the instruction.

[0065] Here, the mode flag is involved. The mode flag can be a field in the data packet, which is used to identify the current control mode (such as left bed mode, right bed mode, or left and right bed synchronous mode). Different mode flags enable the sub-controller to determine whether to execute the corresponding control according to the identification mode flag set by itself.

[0066] Here, the command assignment is involved. The command assignment in the data packet is used to indicate the field of the specific action to be executed, such as adjusting to a specific height, angle, etc. It is the core part of the control instruction, which directly determines the action type of the sub-driving element.

[0067] Here, the execution data is involved. The execution data is the specific numerical value of the operation, such as the target height, angle, etc., which is used for the sub-driving element to accurately execute the action indicated by the command assignment.

[0068] When transmitting the control instruction, it is encoded and transmitted in the form of a data packet. The form of the data packet ensures efficient transmission of the control instruction. The mode flag, command assignment, and execution data contained in the data packet ensure that the system can correctly identify and execute the control instruction. The introduction of the mode flag enables the system to intelligently identify the control intention, such as distinguishing between the individual control of the left bed and the right bed, or the synchronous control of the left and right beds, i.e., the mode flag provides the type information of the instruction, the command assignment specifies the specific control action, and the execution data is the quantitative parameter of the control action. This greatly improves the accuracy of control and the flexibility of operation, and the user can select different control modes according to actual needs, thereby simplifying the use process.

[0069] As an optional embodiment, the target driving element is an electric push rod, and the electric push rod comprises a target motor and a screw rod, wherein the target motor is connected with the screw rod, and the target motor is used to drive the screw rod to extend or retract.

[0070] In this embodiment, the setting of the target driving element is illustrated.

[0071] Among them, the electric push rod is involved, which is a linear motion actuator composed of a motor and a screw rod (usually a lead screw or a threaded shaft), and optionally, a transmission assembly (such as gears, bearings, etc.) that can be composed of, used to convert the rotary motion of the motor into linear motion, to achieve the action of pushing or pulling.

[0072] Among them, the target motor is involved, which is the motor part in the electric push rod, used to provide power to drive the screw rod to rotate, and then realize the extension and retraction of the push rod.

[0073] Among them, the screw rod is involved, which is one of the core components of the electric push rod. The target motor drives the screw rod to rotate, and the screw rod is connected with the push rod (or other connecting parts) through threads, converting the rotary motion into linear motion, so as to achieve the effect of extending or retracting the push rod, and then adjust the height of the bed frame.

[0074] The above-described electric push rod mechanism is the core execution part of the height adjustment of the electric bed. When the target controller 20 (or the sub-controller) receives the instruction to adjust the height of the bed frame, it will send a control signal to the target driving element (i.e. the electric push rod). After receiving the signal, the target motor starts to drive the screw rod connected thereto to rotate. Since there is a threaded connection between the screw rod and the push rod, the rotary motion of the screw rod will be converted into the linear motion of the push rod, i.e. elongation or shortening, so as to adjust the height of the bed frame sub-area connected with the electric push rod. The electric push rod can provide very precise extension and retraction control, making the adjustment of the bed frame height more delicate and smooth, and improving the user experience.

[0075] As an optional embodiment, the target bed body 10 is provided with a gravity detection device, and the target driving element is a movable driving element, and the gravity detection device is used to detect gravity to determine the moving position of the movable driving element according to the gravity.

[0076] In this embodiment, the target bed body 10 is provided with a gravity detection device, and the target driving element is a movable driving element.

[0077] The target driving element is designed as a mobile driving element, which means it has the ability to move within the bed body. This design allows the driving element to move freely under the bed frame inside the electric bed, enabling non-fixed and dynamic control of different areas of the bed frame.

[0078] The gravity detection device is a sensor device used to measure and detect changes in gravity or direction. In the context of an electric bed, the gravity detection device can sense the user's weight distribution or adjustment needs, thereby determining the position to which the mobile driving element needs to move.

[0079] When the target driving element is designed as a mobile driving element, the flexibility and adaptability of the electric bed are significantly improved. Traditional fixed driving elements are usually fixedly connected to a specific area of the bed frame and can only control the height or inclination of that area. Mobile driving elements break this limitation and can move within the bed body as needed to control any area of the bed frame. Not only does this simplify the design and manufacturing process of the electric bed, but it also greatly enhances the bed's ability to quickly respond to different user needs. Moreover, the introduction of a gravity detection device in the electric bed allows for intelligent sensing of the user's weight distribution, and then automatically determines the movement position of the mobile driving element based on changes in gravity. That is, the gravity detection device can measure the user's pressure distribution on the bed body and identify areas that need additional support or adjustment. For example, when the user lies on the bed, the gravity detection device can sense the weight of the back or legs, and then automatically determine the movement path of the mobile driving element to move to these areas, providing precise height or inclination adjustment.

[0080] As an optional embodiment, the target bed body 10 is a spliced bed body obtained by splicing multiple sub-bed body parts.

[0081] In this embodiment, it is explained that the target bed body 10 is a spliced bed body obtained by splicing multiple sub-bed body parts.

[0082] The sub-bed body is the basic unit that makes up the spliced bed body. Each sub-bed body is an independently adjustable bed body part, which can be the head, tail, middle, or left and right bed body parts. Each part may contain independent driving elements, controllers, etc.

[0083] The spliced bed body is a multi-segment bed structure formed by connecting multiple sub-bed bodies in a detachable or splicable manner. The spliced bed body can adapt to various room sizes and allow users to change the shape and size of the bed according to personal preferences or usage scenarios.

[0084] The target bed body 10 is a spliced bed body spliced by multiple sub-bed body parts, which means that the main structure of the electric bed is designed to be composed of multiple independent sub-bed bodies that can be controlled and adjusted independently, and are connected through flexible splicing between them to form a whole spliced bed body. This design makes the electric bed easily adapt to various room layouts and user needs, and users can freely adjust the length, width and even shape of the bed by increasing or decreasing the number of sub-bed bodies to meet specific use scenarios, such as large rest areas during family gatherings, or adjustment needs for different areas of the bed during sleep.

[0085] As an optional embodiment, the target bed body 10 is provided with a clamping jaw, which is used to fix the mattress when adjusting the height of the bed frame.

[0086] In this embodiment, the target bed body 10 is provided with a clamping jaw, which is used to fix the mattress when adjusting the height of the bed frame.

[0087] Among them, the clamping jaw is a device for fixing or grabbing objects, specifically referring to a mechanical device installed on the surface or edge of the electric bed, used to stably fix the mattress during the height adjustment of the bed frame, preventing the mattress from sliding or shifting when the bed frame moves.

[0088] The clamping jaw is provided on the target bed body 10, and the purpose of this design is to provide stability for the mattress during the height adjustment of the bed frame. Since the lifting or tilting of the bed frame may cause the mattress to slide on the bed surface, affecting the safety and comfort of the user, the clamping jaw can be installed on the edge or surface of the mattress in contact with the bed frame, which can grab the mattress during the adjustment of the bed frame, ensuring that the mattress is stable and immovable, even if the bed frame is lifted or tilted greatly, the mattress can remain in place, providing stable support.

[0089] According to an aspect of an embodiment of the present application, an electric bed adjustment system is provided, comprising: the electric bed described above, and a remote control device, wherein the remote control device is wirelessly connected to the height-adjustable bed.

[0090] Among them, the remote control device is used to remotely control the devices of the electric bed adjustment system, which can be a traditional remote control, or a smart device such as a smartphone or tablet computer with wireless connection function.

[0091] Among them, the wireless connection refers to the wireless communication technology between the remote control device and the electric bed, such as Bluetooth, Wi-Fi, infrared or 2.4G wireless technology, allowing users to wirelessly control the electric bed within a certain range without direct contact or wired connection.

[0092] The electric bed adjusting system provided in the application includes an electric bed itself and a remote control device, so that the user can freely and conveniently adjust the height, inclination and other functions of the electric bed to match personal preferences and health needs. The remote control device establishes communication with the electric bed through wireless connection technology, and the user can control the lifting and tilting actions of the electric bed through a simple operation interface without needing to approach the bed body or find a wired interface, greatly improving the flexibility and convenience of use. Moreover, the electric bed itself introduces a distributed sub-controller network and a sub-area bed frame that can be independently adjusted, solving the technical problems of complex height adjustment of the bed body and the need for area and controller pairing in the prior art.

[0093] As an optional embodiment, a display screen is arranged in the remote control device to determine the bed frame area control mode through the display screen interface.

[0094] In this embodiment, it is illustrated that a display screen is arranged in the remote control device.

[0095] Among them, the display screen interface is provided with the selection of multiple modes, and the corresponding codes of multiple modes can be input through the selection of multiple modes, and the corresponding codes are sent to the corresponding controllers to control the specific functions of the device. The bed frame area control mode allows the user to specify the control of one or several areas of the bed frame during the adjustment of the electric bed. This mode allows the user to adjust the local height or inclination of the bed frame according to the actual needs, such as adjusting the specific parts of the bed body. The user can quickly and intuitively select the control area of the bed frame through the display screen interface operation, avoiding the need to find the corresponding control options on the smart device, and the operation is more efficient.

[0096] As an optional embodiment, the display screen interface is provided with multiple modes, and the multiple modes correspond one-to-one to multiple bed frame area control modes.

[0097] In this embodiment, the display screen interface can have multiple modes for selection.

[0098] Among them, the multiple mode selection on the display screen interface is involved, and a certain mode is selected through interface operation, and each mode corresponds to a specific code for controlling different functions or modes.

[0099] Among them, multiple mattress area control modes are involved, and this control mode allows the user to independently control different areas of the bed body to adapt to different needs, such as comfortable positions when reading, watching TV or sleeping.

[0100] The display screen interface has multiple mode selections, and each mode corresponds to a different mattress area control mode, which provides an intuitive and fast control method, allowing the user to directly select the mattress area to be adjusted without the need for smart devices or complex menus. The user only needs to select a mode through the interface operation, and the system can identify the corresponding code to automatically switch to the preset mattress area control mode and start adjusting the height or inclination angle of the selected area.

[0101] Based on the above embodiments and optional embodiments, an optional implementation is provided, which is described in detail below.

[0102] The utility model discloses a main control box is matched with remote controller, and the operation system that can be compatible with single bed and can be applied to intelligent left and right bed is developed. Figure 2 It is a schematic diagram of the control box module structure provided by the optional implementation of the utility model, Figure 3 It is a schematic diagram of selecting the control bed body area, as shown in Figure 2 、 3 The control box has a serial port, and multiple control boxes can be connected in series during use. The control box has a default synchronization mode when it is shipped. When there is no signal in the serial port, the control system is a general single bed control system. When there is a signal in the serial port, it means that the control system is a series connection of multiple control boxes. At this time, multiple remote controllers can issue instructions to the control system. The control box also includes a receiving module, an identification module and a transmitting module to perform corresponding functions through hardware arrangement. The execution unit can be understood as a driving element to perform corresponding operations. The following takes a left and right bed as an example (two control boxes in series) to explain the operation logic of the whole system. That is, the above-mentioned two sub-area bed frames, two sets of sub-driving elements and two sub-controllers (two control boxes in series) are taken as examples to explain.

[0103] (I) The first control mode (two control boxes and one remote controller, used for left and right beds):

[0104] The left and right bed control system is a control box and a remote controller, plus a single control box. The two control boxes of the left and right bed are connected by wire and transmit data through serial communication.

[0105] The left and right bed control box has a default left and right bed mode (synchronization mode) when it is shipped. When both control boxes are in left and right bed mode, left and right bed initialization setting is needed through the remote controller. That is, when receiving the remote controller signal, the control box communicating with the matching remote controller defaults to the host, and the other control box connected to the host by wire is the slave. After successful setting, the host is one of the beds (such as the right bed), and the slave automatically switches to the other bed mode.

[0106] The remote controller is paired with one of the control boxes through 2.4G wireless, the control box is the master, and the other control box connected by wire is the slave. The remote controller selects the mode through the display screen interface, which is left bed, right bed and left and right bed three modes, and the current remote controller sending mode is set through switching.

[0107] It should be noted that when the remote control operation is performed, the remote controller data is controlled, the remote controller sends the target control instruction, and the data packet of the target control instruction includes the following: mode flag + command assignment + execution data.

[0108] That is, the remote controller can switch the left bed, right bed and left and right bed three modes, and the instruction data packet sent in different modes will be attached with different mode flags. The master first receives the signal and identifies the mode flag, and then sends the signal to the slave. Each control box only executes the instruction with its own mode flag, and if the corresponding mode flag cannot be detected, the instruction will not be executed.

[0109] According to the current mode setting instruction of the remote controller, the mode flag bit is added in the data packet, each control box has different identification mode flags, the master receives the target control instruction sent by the remote controller, and simultaneously transmits the cooperative control instruction to the slave through the serial port. The master and the slave judge whether to execute the instruction action according to the mode flag bit in the data packet of the instruction.

[0110] Table 1 is a table of identification mode flags of the control box and mode flags of the remote controller in the first control mode under the preset state, as shown in Table 1:

[0111] Table 1

[0112] After initialization settings: Master Slave Synchronization Identification mode flag of the control box 2 1 No Mode flag of the remote controller 1 2 0

[0113] Figure 4 It is the control flow chart when the master is the left bed provided by the optional embodiment of the utility model, Figure 5 It is the control flow chart when the master is the right bed provided by the optional embodiment of the utility model, Figure 6 It is the flow chart of the overall judgment logic after the initialization setting provided by the optional embodiment of the utility model, as Figure 4 、 5And 6, when the control box identification mode flag and the remote control sent mode flag is not "0", and the same, the control box to the execution unit sent command assignment is "0" + execution data, at this time the data zero, execution unit does not execute "execution data"; When the control box identification mode flag and the remote control sent mode flag is not "0", and not the same, the control box to the execution unit sent command assignment is "0x03" + execution data, at this time the execution unit executes "execution data", then the data zero; When the remote control sent mode flag is "0", the control box identification mode flag and the remote control sent mode flag must be different, the control box to the execution unit sent command assignment is "0x03" + execution data, at this time the execution unit executes "execution data", then the data zero; For example: the remote control sends "1" + "execution data", the host identification mode flag is "2", that is, send command assignment "0x03" + execution data, the execution unit executes "execution data"; The host receives the remote control data at the same time the data is transmitted to the slave, the identification mode flag of the slave is "1", that is, send command assignment "0" + execution data, the execution unit does not execute "execution data"; The remote control sends "0" + "execution data", the host and the slave send command assignment "0x03" + execution data, the execution unit executes "execution data"; The remote control sends command zero after the hand, the control box receives the sent command has the change for "0" when processing execution data, execution data is cleared after processing (that is, the control box is in the receiving state when receiving the signal, and changes to the execution state when the receiving signal is terminated, and returns to the receiving state after execution).

[0114] (ii) the second control mode (two control boxes and two remote controls, left and right beds are used):

[0115] The control method of the second control mode is the same as that of the first control mode, and the second control mode has two remote controls and two control boxes, which are one-to-one corresponding. During initialization setting of the left and right beds, the first control box paired with the first remote control is the host, and the second control box is the slave. At this time, the first control box sends instructions from the first remote control, which is the same as the first control mode.

[0116] The difference lies in that: the user can randomly use one of the two remote controls each time, and the control box paired with the remote control is the host, and the other control box is the slave. The host receives the remote control data and transmits the data to the slave through the serial port at the same time.

[0117] That is, the host and the slave are not fixed. The one that receives the signal of the corresponding remote control and sends the signal to the other control box is the host, and the one that receives the signal through the serial port is the slave.

[0118] (ii) the third control mode (one control box and one remote control, only for single bed use):

[0119] Figure 7 is a flow chart of the judgment logic of the single-bed usage provided by the optional embodiment of the utility model, and the third control mode is as shown in the figure. Figure 7

[0120] Table 2 is a table of the identification mode mark of the control box and the mode mark of the remote controller in the preset state under the third control mode, as shown in Table 2.

[0121] Table 2

[0122] Before initialization settings: Master Slave Synchronization Identification mode flag of the control box No No 0 Mode flag of the remote controller 1 2 0

[0123] When the serial port of the control box is idle, initialization setting will not be performed, that is, the control box keeps the left and right bed mode (synchronous mode), no matter whether the mode mark sent by the remote controller is "0", the identification mode mark of the control box is "0", the control box sends the command assignment "0x03" + execution data, and the execution unit executes the "execution data"; under the third control mode, the mode mark sent by the remote controller is no longer important, and the control box will send the command assignment "0x03" + execution data, and the execution unit executes the "execution data". The adaptive remote controller can be a display screen remote controller or a remote controller (1, 2 and 3) with a dial switch in hardware design, and can also be expanded into an operable device, including a remote controller, a voice controller, a mobile phone APP, etc.

[0124] Through the above optional embodiment, at least the following beneficial effects can be achieved:

[0125] 1) One remote controller of the system can arbitrarily switch between the left bed mode, the right bed mode and the left and right bed synchronous mode to control the control box, compared with the original technology in which the left and right master control boxes are respectively paired with remote controllers, one remote controller can be reduced.

[0126] 2) The system is equivalent to a single control mode when switched to the left bed mode and the right bed mode, compared with the original technology in which the synchronization connection line between the two master control boxes must be pulled out to realize the single control mode, and the system is more operable.

[0127] 3) The control box and the remote controller of the conventional electric bed control system are generally one-to-one paired and complete, and the left and right bed control system of the present scheme is compatible with single bed and left and right bed, which means that one set is a single bed control system, two sets are a left and right bed control system, and N sets are a multi-bed linkage control system.
