DETAILED DESCRIPTION

[0043] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0044] With the development of new technologies, the Internet of Things and artificial intelligence, as emerging technologies, have been widely used in more and more industries, and therefore have greater demand for related product development and teaching research. The Artificial Intelligence & Internet of Things (AIOT) development platform is an intelligent embedded hardware platform, including a motherboard and a daughterboard. The combination of the motherboard and the daughterboard can simulate the construction of products, so it can be used for verification development and teaching training. At present, there are some AIOT development platform design solutions in the industry, such as the Internet of Things experiment box, but they are usually applied to a single field, the product content and mode are relatively fixed, and it is difficult to expand the scope of application. There are still great limitations in development and teaching.

[0045] In order to solve the above technical problems, the present disclosure provides a daughter board, including a substrate, and a functional module and a first communication interface arranged on the substrate, the functional module is used to realize the corresponding function, and the first communication interface is electrically connected to the functional module, and is used to transmit information between the functional module and the motherboard. By integrating different functional modules on different daughter boards, and combining the daughter boards with different functions with the motherboard of the development platform, the functions of the development platform can be flexibly set according to actual needs, which greatly expands the basic functions and application scope of the development platform.

[0046] An exemplary embodiment of the present disclosure provides a daughter board, such as Figure 1As shown, the sub-board 1 includes a substrate 2, a functional module 3, a collection unit 5 and a first communication interface 4. The functional module 3, the collection unit 5 and the first communication interface 4 are all arranged on the substrate 2, that is, the substrate 2 is a carrier of the functional module 3, the collection unit 5 and the first communication interface 4, which can be any type of substrate, such as a printed circuit board, etc.

[0047] Functional module 3 is used to realize the corresponding function, which can be a module integrated on substrate 2 in a modular packaging form, including relevant chip modules or relevant components of the corresponding function. For example, if the function corresponding to sub-board 1 is an infrared remote control function, then functional module 3 may include an infrared radio frequency module for transmitting infrared radio frequency signals to the controlled object according to control information. For another example, if the function corresponding to sub-board 1 is a communication function, then functional module 3 may include a wireless communication module for wireless communication by transmitting wireless signals with the target device, and there is no limitation on this.

[0048] The acquisition unit 5 is used to collect target information. Target information refers to the information required by the sub-board 1 to realize the corresponding function. For example, the target information may refer to the control information input by the user, so that the sub-board 1 can perform the corresponding action according to the control information. Or it can also be the user's body temperature, fingerprint and other biological information, so that the sub-board 1 can collect the user's biological information data for physical health monitoring. Or it can also be environmental information such as air humidity and ultraviolet intensity, so that the sub-board 1 can be used as an environmental monitoring device. Of course, the target information is not limited to the above three types, and it is only used for illustration here.

[0049] The first communication interface 4 is electrically connected to the function module 3, and is a circuit interface connecting the function module 3 and the motherboard of the development platform, and can be used to transmit information between the function module 3 and the motherboard. The first communication interface 4 can be connected to the motherboard in a variety of ways, such as directly connecting to the second communication interface on the motherboard, or indirectly connecting to the motherboard through other devices such as other daughter boards and development platform boxes, and there is no limitation on this.

[0050] The first communication interface 4 is also electrically connected to the acquisition unit 5, and the first communication interface 4 can transmit the target information collected by the acquisition unit 5 to the motherboard, so that the motherboard can perform corresponding actions according to the target information. For example, when the function of the sub-board 1 is to collect environmental humidity, the acquisition unit 5 can include a humidity sensor, and the target information is the environmental humidity value. After the acquisition unit 5 detects the environmental humidity value, the first communication interface 4 can transmit the environmental humidity value to the motherboard, so that the motherboard can further transmit the environmental humidity value to other sub-boards such as the communication sub-board or the storage sub-board. In this way, an environmental humidity monitoring platform can be built based on the development platform to realize dynamic monitoring of environmental humidity.

[0051] By adopting such a setting method, different functional modules 3 and acquisition units 5 are integrated on different sub-boards 1, so that each sub-board 1 can realize its corresponding function respectively. At the same time, the functional module 3 and the acquisition unit 5 are electrically connected to the first communication interface 4, and are further connected to the motherboard through the first communication interface 4. Therefore, by selecting the sub-board 1 corresponding to the required function and using it in combination with the motherboard and other sub-boards, the product verification development and teaching training content of the development platform can be flexibly adjusted, which greatly expands the basic functions and application scope of the development platform, avoids the inefficiency caused by repeated board making in the conventional development process, and at the same time, the development platform can also be used as the core experimental equipment for related professional teaching and scientific research, and cultivates application-oriented artificial intelligence Internet of Things technical talents with comprehensive skills.

[0052] In one embodiment, if Figure 2 As shown, the functional module 3 includes a wireless communication module 31. The wireless communication module 31 can be used to wirelessly communicate with the target device, so that the sub-board 1 has a wireless communication function. At this time, the sub-board 1 can be used as a wireless communication sub-board to participate in the construction of products that need to be implemented based on wireless communication. For example, the sub-board 1 can be used to build a wireless router to provide a wireless network environment. Or the sub-board 1 can also be used to simulate electronic devices such as mobile phones, smart watches, and laptops to realize the wireless communication function of electronic devices. The wireless communication module 31 is electrically connected to the first communication interface 4, and can be mounted on the development platform through the first communication interface 4 to realize wireless communication between the motherboard of the development platform and the target device. The target device can be other electronic devices with wireless communication functions, such as Bluetooth speakers or mobile phones, etc., without limitation.

[0053] As an example, when the motherboard needs to send information to the target device, the motherboard can first transmit the information to the wireless communication module 31 through the first communication interface 4, and then the relevant components in the wireless communication module 31 send the information to the corresponding target device. When the target device needs to send information to the motherboard, the relevant components in the wireless communication module 31 can first receive the information sent by the target device, and the wireless communication module 31 then transmits the information to the motherboard through the first communication interface 4, thereby realizing the wireless communication between the motherboard and the target device. By setting the wireless communication module 31, wireless communication and development can be carried out based on the development platform, for example, it can be linked with other devices with wireless communication functions to jointly build a product prototype. Of course, the sub-board 1 can also be connected with other sub-boards to realize wireless communication between other sub-boards and the target device, so that other sub-boards without wireless communication functions can also send and receive wireless communication information, and its implementation path can refer to the motherboard, which will not be repeated here.

[0054] According to different wireless communication needs, the wireless communication module 31 may include different communication modules, for example, it may include one or more of a wireless fidelity (Wireless-Fidelity, Wi-Fi) communication module, a Bluetooth (Bluetooth) communication module, a ZigBee (ZigBee) communication module, a long range radio (Long Range Radio, LoRa) communication module and a radio frequency (Radio Frequency, RF) communication module.

[0055] In one embodiment, the wireless communication module 31 may include a Wi-Fi communication module and a Bluetooth communication module, so that the sub-board 1 has Wi-Fi communication function and Bluetooth communication function, and can be used as a wireless communication sub-board to wirelessly communicate with various target devices such as mobile phones, smart watches, Bluetooth headsets, etc. For example, a wireless router can be simulated in a home to connect various smart home appliances such as smart speakers, smart air conditioners, and sweeping robots to a wireless network, so that users can check the use status of these smart home appliances at any time through applications on electronic devices such as mobile phones and smart watches, and remotely control smart home appliances through a development platform equipped with a wireless communication sub-board to create a smart home scene.

[0056] In one embodiment, the wireless communication module 31 may include a LoRa communication module, so that the sub-board 1 has the LoRa communication function. At this time, the sub-board 1 can be used as a LoRa communication sub-board, so that the motherboard can realize LoRa communication. LoRa communication has the characteristics of long distance, low power consumption, strong anti-interference ability, strong penetration, and high security, which is highly consistent with the needs of industrial applications. Therefore, the LoRa communication sub-board can be used to simulate industrialization scenes, and of course it can also be used to build some industrial product prototypes in teaching experiments. For example, product prototypes for scenes such as urban intelligent systems, agricultural Internet of Things environmental monitoring, and logistics distribution can be built. In addition, the LoRa communication sub-board can also be used to create smart home scenes, such as building temperature and humidity monitoring systems, intelligent switch systems, and smoke alarm systems, so that users can find abnormal conditions at home in time.

[0057] In one embodiment, the acquisition unit 5 of the wireless communication sub-board may include a sub-board switch. The sub-board switch may be, for example, a switch in the form of a dip switch, a knob switch, or a button, and may enable and disable the wireless communication function of the wireless communication sub-board. When the functional module 3 of the wireless communication sub-board includes multiple communication modules, the acquisition unit 5 may also include a mode switching switch, which may also be, for example, a switch in the form of a dip switch, a knob switch, or a button, and the user may select a wireless communication function from the multiple wireless communication functions of the wireless communication sub-board through the mode switching switch.

[0058] In one embodiment, if Figure 3As shown, the acquisition unit 5 includes a bioresistor 51. The bioresistor 51 is used to collect biological information of the target information, and the acquisition method can be, for example, touch. In actual use, the user only needs to contact the skin tissue part of the finger or the like with the bioresistor 51 to complete the acquisition, and the operation is simple and quick. The setting quantity and setting position of the bioresistor 51 can be set according to actual needs, and there is no restriction on this. For example, there can be two bioresistors 51, and the two bioresistors 51 are located on the same surface of the substrate 2 and are respectively located on both sides of the length direction of the substrate 2. It is convenient for the thumbs of both hands of the user to be easily placed on the two bioresistors 51 to collect body fat information, thereby improving the user experience.

[0059] Through the bio-resistance 51, the sub-board 1 can collect the user's biological information. The bio-resistance 51 is electrically connected to the first communication interface 4, and the collected biological information can be transmitted to the motherboard through the first communication interface 4. The motherboard can further transmit the biological information to the data analysis sub-board, and the data analysis sub-board analyzes the biological information to obtain the user's body fat percentage and other physical information. The motherboard can transmit the body information such as the body fat percentage to the display sub-board, and the user can directly view the relevant information on the display sub-board. Alternatively, the motherboard can also transmit the body data such as the body fat percentage to the communication sub-board, and the communication sub-board uploads it to other wireless communication devices to achieve data synchronization and storage, and the user can view the relevant information at any time through the application on the electronic devices such as mobile phones and smart watches.

[0060] By flexibly combining the sub-board 1 provided with the bio-resistance 51 with the motherboard and other sub-boards, a variety of health monitoring product prototypes can be built. For example, the sub-board 1 can be used as a body fat scale sensor sub-board, a heart rate sensor sub-board and a thermometer sensor sub-board, and participate in the construction of a body fat scale, a heart rate detector and a thermometer, providing users with accurate data on body fat rate, heart rate and body temperature, helping people to understand their physical condition more comprehensively. Furthermore, targeted health suggestions and reminders can be made based on the user's physical data, so as to better help users formulate and adjust fitness plans, diet plans, etc., and achieve health goals.

[0061] In one embodiment, if Figure 4 As shown, the acquisition unit 5 includes a control button 52, and the control button 52 is used to acquire control information as target information. The user can input corresponding control information to the sub-board 1 by operating the relevant control button 52, so that the sub-board 1 performs a corresponding action. At the same time, the control button 52 is also electrically connected to the first communication interface 4, so that the user can control the motherboard or other sub-boards through the control button 52.

[0062] In one embodiment, the control button 52 includes a direction button 521. The direction button 521 is electrically connected to the first communication interface 4, and is used to collect direction information as control information. As an example, the direction button 521 can be, for example, a four-way control button, and the direction information of its four key positions are upward, right, downward, and left in the clockwise direction. The sub-board 1 collects the corresponding direction information according to the user's pressing action on different key positions of the direction button 521, so as to realize the corresponding direction control function. Of course, the direction button 521 can also be other button forms, which is not limited to this.

[0063] In one embodiment, the control button 52 includes a volume button 522. The volume button 522 is electrically connected to the first communication interface 4, and is used to collect volume adjustment information as control information. As an example, the volume button 522 can be a bidirectional control button, and the volume adjustment information of its two key positions are volume up and volume down respectively. The sub-board 1 collects the corresponding volume adjustment information according to the user's pressing action on different key positions of the volume button 522, so as to implement the corresponding volume adjustment control function. Among them, the volume button 522 can be an up-down bidirectional button, or a left-right bidirectional button, and of course it can be other button forms, which are not limited to this.

[0064] In one embodiment, the control button 52 includes an execution button 523. The execution button 523 is electrically connected to the first communication interface 4, and is used to collect execution information as control information, wherein the execution information may include one or more of open, close, confirm, and cancel. In one example, the execution button 523 may be, for example, a push button, and the execution information of opening or closing may be input alternately by pressing the button. In another example, the execution button 523 may be, for example, a bidirectional control button, and the execution information of its two key positions is confirm and cancel respectively. The number of execution buttons 523 and the button form may be flexibly designed, and there is no restriction on this.

[0065] In one embodiment, the control button 52 includes a custom button 524. The custom button 524 is electrically connected to the first communication interface 4, and is used to collect custom information as control information. The custom information may include information corresponding to the function of the sub-board 1 in addition to direction information, volume adjustment information and execution information. For sub-boards 1 with different functions, the custom information collected by their custom buttons 524 may also be different. For example, when the sub-board 1 is used to remotely control the flight of an unmanned aerial vehicle, the custom information may include the flight speed gear selection of the unmanned aerial vehicle. When the sub-board 1 is used to select a TV channel, the custom information may include channel plus one and channel minus one. The number of settings, setting positions, button forms and specific execution information of the custom buttons 524 can be flexibly designed according to the functions of the sub-board 1, including but not limited to the above embodiments, without limitation. In some embodiments, the user can also freely set the function corresponding to the custom button 524 through the motherboard or other sub-boards. For example, the custom button 524 can be changed from the original flight speed gear selection button to a TV channel selection button, so that the sub-board 1 that was originally used for remote control of drone flight can also be used to select TV channels. In this way, the function of the sub-board 1 can be flexibly adjusted as needed, greatly expanding the application scope of the sub-board 1.

[0066] According to the corresponding functions of the sub-board 1, the direction keys 521, the volume keys 522, the execution keys 523 and the custom keys 524 can be flexibly matched. In one example, when the sub-board 1 is used for a game console handle, the control keys 52 may include the direction keys 521, the volume keys 522, the execution keys 523 and the custom keys 524, so that the user can complete various game operations through the sub-board 1. In another example, when the sub-board 1 is used for a smart speaker, the control keys 52 may only include the volume keys 522 and the custom keys 524, but not the direction keys 521 and the execution keys 522.

[0067] In one embodiment, the functional module 3 includes an infrared radio frequency module 32. The infrared radio frequency module 32 is electrically connected to the first communication interface 4, and can emit a corresponding infrared radio frequency signal under the control of the control button 52, so that the sub-board 1 can have the function of actively sending infrared signals, which makes up for the deficiency that the existing sub-board can only passively receive infrared signals, and meets the infrared remote control requirements of the development platform. In actual use, by using the infrared radio frequency signal emitted by the infrared radio frequency module 32, the sub-board 1 can be used as a remote control sub-board to realize the remote control of equipment in a specific production environment. For example, it can be used as a TV remote control sub-board to remotely control the switch, volume adjustment, channel switching, etc. of the TV set, and for example, it can be used as an air conditioner remote control to remotely control the switch, temperature selection, mode selection, timing, etc. of the air conditioner. At the same time, the infrared radio frequency module 32 enables the sub-board 1 to be used in conjunction with the motherboard and other sub-boards, for example, it can be used in conjunction with the screen sub-board to build a TV program playback platform, or it can also be used in conjunction with the actuator sub-board to build a smart car platform, etc., which greatly increases the use scenarios.

[0068] In one embodiment, the infrared radio frequency module 32 includes a frequency modulation component 321 for adjusting the frequency of the infrared radio frequency signal emitted by the infrared radio frequency module 32. Specifically, the sub-board 1 can be tuned to a corresponding frequency according to the remote control device so that the infrared radio frequency signal can match the remote control device. In this embodiment, through the frequency modulation component 321, the infrared radio frequency module 32 can send an infrared radio frequency signal of a specific frequency according to actual needs, thereby simulating most remote controls in the current market through the sub-board 1 and replacing these remote controls.

[0069] As mentioned above, the daughter board 1 has a first communication interface 4. The first communication interface 4 can be used to transmit information between the functional module 3 and the motherboard. In some practical examples, the motherboard can also power the functional module 3 through the first communication interface 4 to support the normal use of the functional module 3 when connected to the motherboard. Figures 2 to 4 As shown, the daughter board 1 also includes a battery 6 disposed on the substrate 2. The battery 6 is electrically connected to the functional module 3 and can supply power to the functional module 3, so that when the daughter board 1 is separated from the mother board, it can also be used for independent power supply, further expanding the application range of the daughter board 1. In some embodiments, the battery 6 is also electrically connected to the first communication interface 4, and the battery 6 can complete power storage through the first communication interface 4.

[0070] In one embodiment, if Figure 5 As shown, the daughter board 1 also includes a magnetic attraction portion disposed on the substrate 2. The magnetic attraction portion is used to connect the daughter board 1 to the motherboard by magnetic attraction, and of course, it can also be used to connect the daughter board 1 to other daughter boards by magnetic attraction, playing a role of fixing and positioning.

[0071] In one embodiment, the magnetic attraction portion is a magnetic foot 7 with a foolproof design, which can prevent the sub-board 1 from being placed incorrectly. The number and arrangement of the magnetic feet 7 can be designed according to the specific settings of other components such as the functional module 3 and the first communication interface 4 on the sub-board 1, and there is no limitation as long as the purpose of stable connection and foolproof can be achieved. For example, refer to Figures 2 to 4 , the magnetic feet 34 can be designed to be arranged in an isosceles trapezoidal shape, or refer to Figure 5 , the magnetic feet 34 can also be designed to be arranged in a right-angled trapezoid. Similarly, the magnetic feet on the motherboard and other daughter boards are also designed to be arranged in an isosceles trapezoid or a right-angled trapezoid. When connecting the daughter board 1 to the motherboard or other daughter boards, the daughter board 1 can be prevented from being inverted. At the same time, the fool-proof design can also be used to avoid connection. For example, the magnetic feet 34 of the daughter board 1 are designed to be arranged in an isosceles trapezoid, and the magnetic feet 34 of another daughter board are designed to be arranged in a parallelogram, so that the magnetic feet 34 of the two cannot match, thereby preventing the daughter board 1 from being connected to the other daughter board.

[0072] In one embodiment, if Figure 1 As shown, the substrate 2 is divided into an edge area 21 and a middle area 22. The edge area 21 surrounds the middle area 22, and the first communication interface 4 can be set on the edge area 21, while the functional module 3 or the acquisition unit 5 can be set in the middle area 22. Of course, the functional module 3 and the acquisition unit 5 can both be set in the middle area 22. With such an arrangement, on the one hand, when the first communication interface 4 is connected to the motherboard or other sub-boards, the sub-board 1 and the motherboard, or each sub-board 1 can overlap well, which is convenient for combined use. On the other hand, sufficient physical space can be provided for the layout of the functional module 3 and the acquisition unit 5, so as to facilitate the design of a variety of functional modules 3 and acquisition units 5 according to different functional needs. At the same time, setting the functional module 3 and the acquisition unit 5 in the middle area 22 is more in line with the public's usage habits and can enhance the user experience.

[0073] An exemplary embodiment of the present disclosure provides a development platform. Figure 6 As shown, the development platform 8 in this embodiment includes the above-mentioned sub-boards 1, and various platforms can be built by carrying the above-mentioned sub-boards 1. The sub-boards 1 in the development platform 8 have substrates 2 of the same specifications and a unified first communication interface 4, which can be compatible with each other and used in a flexible combination, thus avoiding the problem of large application limitations of traditional development platforms.

[0074] The development platform 8 may also include a motherboard 9. Based on the development platform 8, the motherboard 9 and different sub-boards 1 can be used in combination. By selecting a suitable sub-board 1, a product can be simulated on the development platform 8 to verify the architecture, algorithm, program, function, etc. of the product development, thereby avoiding repeated board building in the conventional development process, saving manpower, material resources, financial resources and time. At the same time, the development platform 8 can also serve as a core experimental equipment that is closely integrated with the teaching and scientific research of IoT-related majors, meeting the needs of students and teachers in learning and researching IoT technologies, and cultivating application-oriented talents that meet social needs.
