Description

Technical Field

[0001] This utility model belongs to the field of massage equipment technology, specifically, it relates to a bus-controlled electric bed or electric sofa controller. Background Technology

[0002] Many modern people experience back pain, stiff neck, and other physical problems due to prolonged sitting and bending over at work. This has led to the development of massage chairs and sofas, which simulate professional massage techniques such as kneading, pushing, and tapping to penetrate deep into muscles, helping to relax tense muscles and reduce fatigue.

[0003] Traditional massage chairs or massage sofas, also known as electric sofas or electric beds, and other smart home devices typically use a central control box to centrally control various functional modules (such as electric adjustment, massage, heating, etc.), which has the following technical drawbacks: Complex wiring: The central control box needs to connect to each module through multiple cables. Since each module is distributed in different parts of the electric bed or electric sofa, the amount of wiring for each module is large and the installation cost is high.

[0004] Maintenance difficulties: When a module fails, the central control box needs to be disassembled. Since there are many modules and a lot of tangled cables, it is time-consuming to sort out and judge the faulty part one by one. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bus-based controller for electric beds or electric sofas.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes: a bus-controlled electric bed or electric sofa controller, comprising one or more RS485 buses, one or more circuit modules, and a control terminal. The RS485 bus connects the corresponding circuit modules in series via twisted-pair cables; Each circuit module has at least one set, one of which includes a Bluetooth receiver, a head motor drive module, a leg motor drive module, a leg massage drive module, a heat therapy drive module, a head massage drive module, a waist motor drive module, a leg motor drive module, and a light strip drive module. The Bluetooth receiver, head motor drive module, leg motor drive module, leg massage drive module, heat therapy drive module, head massage drive module, waist motor drive module, leg motor drive module, and light strip drive module are connected in series with the RS485 bus. The control terminal is used for user operation and is wirelessly connected to the RS485 bus via a Bluetooth receiver.

[0007] Furthermore, the control terminal is a wireless controller.

[0008] Furthermore, the wireless controller includes one or more of a remote control, a touch screen control terminal, and a voice control terminal, all of which are equipped with a Bluetooth communication module and connect to a Bluetooth receiver via wireless transmission.

[0009] Furthermore, both the Bluetooth receiver and the Bluetooth communication module use 2.4G wireless communication.

[0010] Furthermore, it also includes a main controller that communicates with the RS485 bus, and an anti-interference circuit is provided between the main controller and the RS485 bus.

[0011] Furthermore, the RS485 bus can also be a CAN bus, with other connection relationships remaining unchanged. The CAN bus connects the corresponding circuit modules in series via twisted-pair cables. Accordingly, at least one CAN bus is set up.

[0012] In simple terms, RS485 is a serial communication protocol for long-distance data transmission, used in industrial and commercial environments where devices require long-distance connectivity. RS485 uses balanced and differential signals and can be transmitted over twisted-pair cables without requiring a separate ground wire.

[0013] In addition, RS485 is less susceptible to noise than other types of serial communication protocols, making it ideal for use in noisy environments.

[0014] The main characteristic of the RS485 standard interface is that it is a balanced transmission standard. It has two pins, one for transmission and one for reception, one for positive and the other for negative. This allows RS485 to create multi-point transmission lines.

[0015] Another advantage of RS485 is that it does not require specific connector or cable standards. Its DB9 connector is commonly used with RS484. This gives system designers more flexibility during the design process.

[0016] Compared with the prior art, the advantages of this utility model include: (1) The present invention provides a bus-based controller for electric beds or electric sofas. The design of multiple circuit modules decomposes and connects each module. If a circuit module fails, the corresponding RS485 bus or CAN bus can be disconnected, which can quickly troubleshoot the problem and is beneficial for after-sales maintenance and replacement.

[0017] (2) The present invention provides a bus-based electric bed or electric sofa controller, which uses RS485 bus or CAN bus to connect the modules in series and connect the corresponding area wires to one place. This eliminates the traditional structure of electric beds or electric sofas that use a central control box and connect the circuit modules with a lot of complicated wires. All modules are in the central control box, and the wiring connection between the modules is very complicated. This invention simplifies the wiring cost, simplifies the layout, and reduces the installation cost. Attached Figure Description

[0035] Working principle of Embodiments 1 and 2: The control boxes of each module are connected in series via CAN bus or RS485 bus 11, and the main controller 13 is connected to CAN bus or RS485 bus 11. After power-on, the module automatically registers. The main control unit sends instructions to each module via the bus (such as querying status and setting parameters). Each module responds to the instructions and reports data (such as current temperature, angle, and pressure value).
