Thus, the communication control is bus-based, the slave devices are intelligent, and the system installation is simple.

[0004] Based on this, the applicant further researched and improved the system to propose a simpler one. Utility Model Content

[0043] The power supply control board 60 is equipped with a first wireless communication module 61 for communicating with the backend server 20. The mobile terminal 30 has a second wireless communication module 31 for connecting with the backend server 20. The second wireless communication module 31 of the mobile terminal 30 and the first wireless communication module 61 of the power supply control board 60 communicate with each other to control whether the power adapter 50 outputs power based on the signal from the mobile terminal 30.

[0044] The remote controller 10, the power supply control board 60, and the execution unit 40 are all equipped with a 2.4G wireless transceiver for wireless communication connection. The remote controller 10 forms a wireless network with several execution units 40 through the 2.4G wireless transceiver.

[0045] Among the several execution units 40, one can be defined as the master and the rest as slaves. The master and slaves communicate with each other via a 2.4G wireless transceiver. The power supply control board 60 is wirelessly connected to the master via a 2.4G wireless transceiver and transmits signals to the master based on the signals from the mobile terminal 30. The remote controller and several execution units form a 2.4G wireless network to cooperate with the data communication between the master and slaves via the 2.4G wireless transceiver, realizing that the remote controller and each execution unit form a network, and the execution units also form a network with each other.

[0047] In this embodiment, the power supply control board 60 is disposed on the power adapter 50 and is connected to the voltage output terminal of the power adapter 50.

[0048] The power supply control board 60 is provided with a power supply output terminal for supplying power to the execution unit 40, an on / off control unit 62 for controlling the on / off of the 24V voltage output terminal and the power supply output terminal, and a first main control module 63 integrating a 2.4G wireless transceiver.

In this embodiment, the on / off control unit 62 includes a resistor R7, a transistor Q2, a MOSFET Q1, resistors R3, R1, R6, and R8. One end of resistor R7 is connected to the base of transistor Q2, and the other end of resistor R7 is the control terminal of the on / off control unit 6214. The base of transistor Q2 is grounded through resistor R8, and the emitter of transistor Q2 is grounded. Resistors R1 and R6 are connected in series. The non-series node of resistor R1 is connected to the source of MOSFET Q1. The source of MOSFET Q1 is the input terminal of the on / off control unit 6214, and the drain of MOSFET Q1 is the output terminal of the on / off control unit 6214. The gate of MOSFET Q1 is connected to the series node of resistors R1 and R6 through resistor R3, and the non-series node of resistor R6 is connected to the collector of transistor Q2.

[0050] It also includes an output current detection circuit 64 for detecting the output current of the power adapter 50. The output current detection circuit 64 is connected to the power supply control board 60 to control the power adapter 50 to stop outputting current when the output current of the power adapter 50 is too high.

[0051] The output current detection circuit can detect and control the output current. When the output current is too large, the power supply to it can be directly disconnected to protect the downstream equipment.

[0052] The execution unit 40 includes a drive control board. In another embodiment, the power supply control board 60 is identical to this embodiment, except that it is located on the drive control board of the host. The drive control board is equipped with a second main control module integrating a 2.4G wireless transceiver and a drive module for driving the execution components.

[0053] The second main control module of the host is connected to the power supply control board 60, the drive module and the power control module respectively, so as to receive signals from the mobile terminal 30 or the remote controller 10 and control itself or the slave drive module to perform corresponding actions.

The vibration motor control board is connected to a positive output terminal, a negative output terminal, and a signal control line. The massage motors are connected in series with the positive output terminal, the negative output terminal, and the signal control line. The vibration motor control board communicates with the massage motors via a single-bus protocol. In specific designs, a gravity sensor can also be configured on the actuator for bed tilt angle detection. It should be noted that other execution units can be: a plug-in or battery-powered Bluetooth speaker, a voice / snoring recognition module, an airbag mattress control unit, a bedside air purification unit, etc.

[0055] The key design feature of this invention lies in its addition of wireless communication modules to several automatic execution units, enabling them to wirelessly connect with the user's intelligent control terminal. This simplifies communication control lines significantly, resulting in a greatly simplified system. During implementation, the number of execution units can be freely increased or decreased, and their physical positions can be adjusted. This greatly facilitates the design, installation, operation, and maintenance of each execution unit in the intelligent bed, eliminating distance limitations caused by wiring and reducing wiring costs. The system bus consists of only two power lines (positive and negative), making wiring connections extremely simple, effectively reducing system complexity and simplifying implementation. Furthermore, the fast data interaction speed contributes to hardware simplification and improved reliability. Additionally, the power supply to the corresponding execution units can be controlled according to usage requirements, significantly reducing energy consumption.

[0056] Secondly, in addition to controlling the corresponding execution unit with a remote control, a mobile terminal can also send a signal to the power supply control board via a Bluetooth module. The power supply control board then sends the signal to the host, which distributes it to the slave unit. This eliminates the need for each execution unit to have a Bluetooth module, greatly speeding up communication efficiency and improving the user experience.

[0057] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
