DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figure 1-Figure 9 ,The RV multi-drive feedback control system shown in the figure includes an interaction end and an execution end;

[0043] The interactive end includes a user interaction module, an environment perception module, and a network communication module. The interactive end obtains instructions to be executed through the user interaction module, the environment perception module, and the network communication module, and transmits the instructions to the execution end through a communication bus;

[0044] The user interaction module includes a control device for providing an operation interface and a control method to the user;

[0045] The environmental perception module includes multiple groups of sensors, and the environmental perception module monitors the temperature and humidity, light intensity, and combustible gas concentration of the sensor RV through multiple groups;

[0046] It should be noted here that the sensors used on the environmental sensing module are multiple groups of sensors of different models and functions, such as temperature and humidity sensors, light intensity sensors, and combustible gas concentration detection sensors. Among them, the sensors used for various monitoring are used as prior art in this application and will not be described in detail here;

[0047] The network communication module includes a remote module, and the network communication module controls and monitors the internal electrical appliances through the remote module;

[0048] It should be noted here that the remote module can be a 4G module and a Lora module, and the internal electrical appliances are controlled and monitored through the remote module. After receiving the instructions transmitted by the interactive end, the execution end executes the corresponding instructions and feeds back the execution results to the interactive end to display the execution status. In addition to executing the instructions, the interactive end can monitor the status of the battery, water tank, etc. through a coulomb meter, a liquid level meter, etc., and feedback protection through the execution end when an abnormal state is detected;

[0049] The execution end includes a monitoring module, an execution module and a protection module. After receiving the instruction transmitted by the interaction end, the execution end executes the corresponding instruction and feeds back the execution result to the interaction end to display the execution status.

[0050] In this embodiment, see Figure 3 As shown, the control part of the execution end includes output signals I / O1 and I / O2, input signal I / O3, transistor 1 and transistor 2 for driving relays, relays for controlling electrical appliances, and optocouplers for feedback of execution status. The relays and electrical appliances form a controlled loop. Under normal circumstances, when the output signals I / O1 and I / O2 are at a high level, the transistors 1 and 2 are controlled to be turned on respectively, so that the relay is energized, the controlled loop is closed, and the electrical appliance starts to work. At the same time, the optocoupler is turned on, and the input signal I / O3 is read as a low level. I / O1 and I / O3 are connected in series through a resistor, so that the output signal and the optocoupler can be detected abnormally with a single pin.

[0051] If the electrical appliances do not work, the possible reasons are: output signal I / O1 failure, transistor failure, optocoupler failure, electrical appliances in the controlled circuit failure, relay failure, etc.

[0052] See also Figure 2As shown, when the execution end receives the instruction from the control end, the control end sets the output signal I / O1 to a high level to drive transistor 1 to conduct, drive the relay to close, close the controlled loop, and the electrical appliance starts to work. If the user feedbacks that the electrical appliance is not working, the input signal I / O3 state is read once, and then the output signal I / O2 is set to a high level to drive transistor 2 to conduct, drive the relay to close, and close the controlled loop. At this time, the input signal I / O3 state is read again, and user feedback is collected. If the electrical appliance works normally at this time, it proves that the backup plan is successfully enabled. In addition, based on user feedback and the input signal I / O3 state read twice, the possible problems in the schematic diagram can be determined, and abnormal information is transmitted to the user at the interactive end, which is convenient for the user to make temporary disposal and later maintenance.

[0054] See also Figure 10-18 In this scheme: the RV multi-drive feedback control system includes the following steps:

[0055] The control device comprises a control body 101, on which a touch screen 102 and a plurality of control keys 103 for controlling the drive are arranged, and a protective component for shielding and protecting the plurality of control keys 103 is arranged on the control body 101, and an adsorption installation component for assisting the control body 101 in being adsorbed and installed on the inner wall of the RV is arranged on the back of the control body 101;

[0056] It should be noted that: during the use of the control device of the user interaction module at the interactive end, the protective component is used to prevent the control key 103 from being accidentally touched and pressed during the operation of the control body 101, resulting in providing wrong operation control instructions to the user, and the control body 101 can be flexibly adjusted through the adsorption installation component when in use, so that the adsorption installation component can be flexibly and stably adsorbed and installed on the inner wall of the RV after use;

[0057] It is worth noting here that the control body 101 has 16 relay output controls on its shell, of which 12 are dedicated to 12V electrical appliances, with a single current supporting a maximum of 20A, and the remaining 4 are on-off outputs that can control 220V AC electrical appliances. Each relay has an independent car insurance that can disconnect the circuit for protection in the event of an accidental short circuit or overload.

[0058] It has 8 dimming control outputs, with a single-channel rated current of 5A, and can adjust the light brightness according to user needs and usage scenarios;

[0060] It has 6 digital signal input interfaces, which can be set as various custom function buttons and various sensor output processing interfaces through programs;

[0061] With 485 communication interface and CAN communication interface, control functions can be realized through a variety of signal transmission methods.

[0062] The protection component includes two groups of U-shaped baffles 201 located in front of each group of control keys 103 for shielding each group of control keys 103. The control body 101 is provided with a flipping component for assisting the U-shaped baffles 201 to flip and connect. The U-shaped baffles 201 are fixed with fixing pins 202 for assisting the U-shaped baffles 201 to flip.

[0063] It should be noted here that: the user interaction module at the interactive end includes a control device, specifically a control body 101, which uses a touch screen 102 and control keys 103 on the control body 101 to provide an operation interface and control method to the user. When the control body 101 is in use, each group of control keys 103 is shielded and protected by two groups of U-shaped baffles 201 to avoid accidental touching and pressing of the control keys 103 during the process of picking up and operating the control body 101, resulting in providing erroneous operation control instructions to the user.

[0064] The flip assembly includes a fixing frame 301 fixed to the outside of the control body 101, a first T-shaped rod 302 is rotatably connected to the fixing frame 301, one end of the first T-shaped rod 302 is fixed to one side of the U-shaped baffle 201, a torsion spring 303 is sleeved on the outside of the first T-shaped rod 302, and both ends of the torsion spring 303 are respectively connected to the fixing frame 301 at one end of the first T-shaped rod 302;

[0065] It should be noted that: the fixing frame 301 and the first T-shaped rod 302 facilitate the rotatable connection of the U-shaped baffle 201, and the torsion spring 303 facilitates the reset of the U-shaped baffle 201 after rotation.

[0066] The adsorption installation component includes a disc 401 fixed on the back of the control body 101, a mounting cavity 402 is provided inside the disc 401, a plurality of groups of sliding grooves 403 are provided on the disc 401, each group of sliding grooves 403 is communicated with the inside of the mounting cavity 402, and each group of sliding grooves 403 is arranged in a ring array state on the disc 401, a slide plate 404 is slidably connected to the slide groove 403, a mounting rod 405 is provided on the outside of the disc 401, one end of the mounting rod 405 is fixed to the slide plate 404, and a suction cup 406 for adsorption is fixed to the other end of the mounting rod 405, and a transmission component for transmitting each group of slide plates 404 and a guide component for guiding during the transmission process are provided inside the mounting cavity 402;

[0067] It should be noted here that: after the control body 101 is used, the groups of suction cups 406 on the back of the control body 101 can be used to adsorb and connect with the wall inside the RV, so that the control body 101 can be quickly installed and fixed at a designated position.

[0068] The transmission assembly includes a driving disk 701 disposed inside the installation cavity 402, a rotating assembly for assisting the driving disk 701 in rotational connection is disposed between the driving disk 701 and the inner wall of the installation cavity 402, a plurality of groups of inclined grooves 702 are provided on the driving disk 701, a driving pin 703 is slidably connected to each group of inclined grooves 702, one end of each group of driving pins 703 is respectively fixed to each group of slide plates 404, and a driving assembly for driving the driving disk 701 in rotation is disposed on the disk 401;

[0069] It should be noted here that: through the mutual cooperation of the driving component and the rotating component, the driving disk 701 is rotated inside the installation cavity 402. During the rotation of the driving disk 701, each group of inclined grooves 702 interacts with each group of transmission pins 703, so that each group of slide plates 404 is driven to move under force. During the movement of each group of slide plates 404, the sliding guiding effect of the fixed block 501 and the second T-bar 502 makes the slide plates 404 move towards or away from each other after being subjected to force.

[0070] The driving assembly includes a rotating shaft 801 rotatably connected to the disc 401, one end of the rotating shaft 801 is located inside the installation cavity 402 and fixed to the driving disc 701, and the other end of the rotating shaft 801 is fixed with a driving pin 802; the rotating assembly includes an annular groove 901 opened on the inner wall of the installation cavity 402, an annular plate 902 is rotatably connected to the annular groove 901, and the annular plate 902 is sleeved and fixed on the outer side of the driving disc 701;

[0071] It should be noted here that: the rotating shaft 801 is driven to rotate through the driving pin 802. During the rotation of the rotating shaft 801, the driving disk 701 is rotated inside the installation cavity 402 through the connecting transmission effect of the rotating shaft 801 and the rotation connection effect between the annular groove 901 and the annular plate 902.

[0072] The cross-sections of the annular groove 901 and the annular plate 902 are arranged in a T-shape;

[0073] It should be noted here that: the cross-section of the annular groove 901 and the annular plate 902 is set in a T-shape, which facilitates more stable rotation connection and rotation transmission operation.

[0074] The guide assembly includes fixed blocks 501 fixed on both sides of the slide plate 404, the fixed blocks 501 are located inside the installation cavity 402, a second T-shaped rod 502 is slidably connected to the fixed blocks 501, and one end of the second T-shaped rod 502 is fixed to the inner wall of the installation cavity 402;

[0075] It should be noted here that: the movement of the slide plate 404 after the force is applied is guided by the two sets of fixing blocks 501 and the second T-shaped rod 502;

[0076] In this embodiment, the user interaction module of the interactive end includes a control device, specifically a control body 101, and uses a touch screen 102 and control keys 103 on the control body 101 to provide an operation interface and a control method for the user. When the control body 101 is in use, two groups of U-shaped baffles 201 are used to shield and protect each group of control keys 103, so as to avoid accidental touching and pressing of the control keys 103 during the process of picking up and operating the control body 101, thereby providing wrong operation control instructions to the user.

[0077] When the control key 103 needs to be pressed, the two groups of U-shaped baffles 201 are pushed away from each other. During the pushing process, the first T-shaped rod 302 on the fixing frame 301 rotates and connects the U-shaped baffles 201, so that the two groups of U-shaped baffles 201 that are subjected to force are turned around the first T-shaped rod 302. Through the turning effect of the two groups of U-shaped baffles 201, the two groups of U-shaped baffles 201 no longer block the control keys 103. At this time, the control keys 103 can be pressed normally.

[0078] After the control body 101 is used, the suction cups 406 on the back of the control body 101 can be used to connect the control body 101 to the wall inside the RV, so that the control body 101 can be quickly installed and fixed at a specified position. In the process of adsorption installation of the control body 101, the driving pin 802 is used to drive the rotating shaft 801 to rotate. In the process of rotation of the rotating shaft 801, the driving plate 701 is rotated inside the installation cavity 402 through the connection transmission effect of the rotating shaft 801 and the rotation connection effect of the annular groove 901 and the annular plate 902. In the process of rotation of the driving plate 701, the groups of inclined grooves 702 are respectively connected to the groups of driving pins 701. 3, driving each group of slide plates 404 to move under force. During the movement of each group of slide plates 404, the sliding guide function of the fixed block 501 and the second T-bar 502 makes the slide plates 404 after being subjected to force slide toward the outer side of the disc 401. Through the sliding of each group of slide plates 404, the suction cups 406 on each group of mounting rods 405 are driven to move away from each other, increasing the spacing between each group of suction cups 406, making it easier to more stably perform the adsorption and installation operation on the control body 101. When the control body 101 does not need to be adsorbed and installed, the suction cups 406 are driven to move closer to each other through transmission, making it easier to store and place the control body 101.

[0079] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
