Detailed Description
Certain aspects and embodiments of the disclosure are provided below. Some of these aspects and embodiments may be applied independently and some of them may be applied in combination, as will be apparent to those skilled in the art. In the following description, for purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the application. It may be evident, however, that the various embodiments may be practiced without these specific details. The drawings and description are not to be regarded as limiting.
As mentioned above, innovative education is a subject based on project learning comprehensive skills, and relates to intelligent hardware connection test, electronic circuit technology teaching, artificial intelligent programming teaching, modeling and other aspects. However, for the above aspects, no integrated solution exists at present, and different application platforms are built for different application environments.
For example, as shown in fig. l, when connection testing of intelligent hardware is performed, connection testing of various sensors (e.g., LED lamp, temperature sensor) and micro-motors is mostly implemented by using conventional terminal devices (e.g., a combination of a computer host and a display), although the computer host has various communication interfaces, such as a USB interface, as part of the conventional terminal devices, the communication interfaces cannot be directly used by the intelligent hardware, but a single chip controller needs to be purchased separately as an interface between the computer host and the intelligent hardware, but the connection is complicated and the cost is high.
In addition, as shown in fig. 2, in the artificial intelligence teaching environment, a card computer such as raspberry pie is generally used, and a separate general display screen is provided to be in communication connection with the card computer such as raspberry pie, so that operations such as connecting a power line and a data line are involved, which results in inconvenience in use and high cost. In addition, a separately configured universal display typically has built-in fixed angle cameras or even no cameras, which can cause inconvenience to students in performing work presentations.
In addition, as shown in fig. 3, when the teaching practice of the electronic circuit is involved, various independent devices and tools such as a universal meter, an electric welding table, a power supply and the like are generally involved, and the devices generally need to be independently powered, so that the system is complicated in wiring, huge in size and certain in potential safety hazard.
For this reason, according to the embodiment of the present disclosure, an integrated teaching experiment device integrating functions such as sensor, commonly used electronic circuit tool and HDMI input, multi-angle camera is provided to satisfy artificial intelligence teaching, intelligent hardware thing networking teaching, multiple teaching demands such as electronic circuit teaching, avoid setting up different application platform to different teaching demands.
According to an aspect of the present disclosure, an integrated teaching experiment device is provided, as shown in fig. 4, including: a main board 430, on which at least one signal interface is integrated, for connecting at least one electronic component outside the integrated teaching experiment device, and performing status monitoring and/or control on the at least one electronic component; an OPS (open pluggable specification) host 41 0 connected to the main board 430 through an OPS daughter card 420; and a display screen 460 connected with the main board and presenting a graphical or code programming environment interface for interaction with a user, so that the user can perform graphical or code programming operation on at least one electronic component externally connected with the integrated teaching experiment device.
Optionally, according to an embodiment of the present disclosure, a microcontroller is also integrated on the motherboard, the microcontroller processing signals from the at least one signal interface and/or generating signals to be output to the at least one signal interface. As an example, the microcontroller may be implemented using a single-chip microcomputer, which processes signals from the at least one signal interface and generates signals to be output to the at least one signal interface.
As an example, the at least one signal interface includes at least one of: an analog input interface; a PWM signal interface; a first serial communication interface; a second serial communication interface; a motor control interface; steering engine control interface. Wherein, the analog input interface can input analog signals, such as photosensitive signals, volume detection signals and the like; a PWM signal interface which can output PWM (pulse width modulation) signals so that signals such as light, sound, etc. can be controlled to continuously vary; the first serial interface may be an I2C interface for I2C communication, for example, to connect hardware such as a common LED display screen, and the second serial interface may be a UART (universal asynchronous receiver transmitter) interface, which may be used to connect hardware such as a bluetooth module; the motor control interface can be used for controlling the operation of the motor; the steering engine control interface can output signals to control the operation angle of the steering engine, wherein the steering engine is a motor capable of controlling angle positioning and is widely applied to the fields of models, robots and the like. As an example, the steering engine control interface may output a PWM signal, and the operating angle of the steering engine may be controlled by programming the duty cycle of the PWM signal, thereby realizing more accurate angle control and improving the performance and stability of the device.
According to the embodiment of the disclosure, the singlechip, the sensor interface and the display screen driving circuit are integrated on the main board and are connected with the OPS host through the OPS sub-card, and in this way, the plurality of sensor interfaces are finally integrated on the integrated teaching experiment device, so that when the intelligent hardware is connected, tested and other teaching, the external sensor is only required to be connected to the sensor interface provided on the integrated teaching experiment device, and compared with the conventional terminal equipment (such as a desktop computer) and the singlechip controller which are used as teaching equipment for the connection test of the intelligent hardware, the complex wiring, the complicated connection process and the high cost can be saved.
In addition, to in artificial intelligence teaching environment, the card type computer such as raspberry group is added external display screen to the conventional use for need be equipped with the display screen alone in teaching process, not only with high costs, moreover use loaded down with trivial details problem, this disclosure has put forward the display screen that utilizes integration teaching experimental apparatus self to be equipped with and not only shows the display signal that comes from OP S host computer, but also can switch and show the display signal that comes from integration teaching experimental apparatus outside (for example, come from embedded development board such as raspberry group, jetson nano), thereby the demand that need be equipped with the display screen alone when adopting card type computer such as raspberry group under artificial intelligence teaching environment is eliminated.
For this reason, this disclosure proposes integrating the HDMI input interface on the mainboard of integration teaching experiment device for display screen drive circuit can follow through HDMI input interface the mainboard receives the outside HDMI display signal from integration teaching experiment device. Specifically, the display screen driving circuit can receive the first HDMI display signal from the OP S host through the OP S daughter card, and receive the second HDMI display signal through the HDMI input interface integrated on the motherboard, wherein the second HDMI display signal comes from the outside of the integrated teaching experiment device.
As an example, the display screen driving circuit may include an HDMI signal selecting circuit to select one of the first HDMI display signal and the second HDMI display signal and supply it to the display screen for display.
Alternatively, when the second HDMI display signal does not appear, the first HDMI display signal is displayed by default, and when the second HDMI display signal appears, the display is automatically switched to the second HDMI display signal, and at this time the first HDMI display signal is operated in the background.
Optionally, the HDMI signal selecting circuit selects by default the first HDMI display signal from the OP S host to be transmitted to the display screen for display, and when the second HDMI display signal appears on the HDMI input interface integrated on the motherboard, the HDMI signal selecting circuit automatically switches to transmit the second HDMI display signal on the HDMI input interface to the display screen for display.
As shown in fig. 5A, the HDMI signal selection circuit may serve as a changeover switch to default the first HDMI display signal from the OPS host to be the screen display signal of the display screen, and when the external HDMI signal line is inserted into the HDMI input interface integrated on the main board, the HDMI signal selection circuit may automatically perform changeover so that the second HDMI display signal from the HDMI input interface integrated on the main board is taken as the screen display signal of the display screen.
Fig. 5B shows a schematic interface diagram of an HDMI signal selection circuit according to an embodiment of the present disclosure. As shown in fig. 5B, the output of the HDMI signal selection circuit may be controlled by the control logic circuit, that is, the input a-path signal and B-path signal may be switched according to the control signal accessed by the control logic circuit, so as to select which path of HDMI signal is transmitted to the display screen for screen display.
As an example, in connection with fig. 5B, the signal for screen display of the display screen may be switched by the input signals EN, SEL1, and SEL2 of the control logic, for example, the a-way signal is selected by a combination of SEL1 and SEL2, for example, sel1=l and sel2=l, while the B-way signal is selected when the input signal EN is kept high. When the external HDMI signal is connected to the HDMI interface of the integrated teaching experiment device, the level (for example, SEL 2) of one of the SEL1 and the SEL2 is changed, so that the switching of the A/B path signals is realized.
In addition, aiming at the situation that in an artificial intelligence teaching environment, a general display screen which is configured independently when a card type computer such as raspberry pie is used conventionally is generally embedded with a camera with a fixed angle or even is not provided with the camera, the student is inconvenient in work display. Therefore, according to an embodiment of the disclosure, the camera with the gooseneck structure can be integrated on the integrated teaching experiment device, so that multidirectional rotation can be realized, and the requirements of shooting at different angles are met.
In addition, the teaching practice of electronic circuits generally involves the use of various separate devices and tools such as a multimeter, an electric welding table, a power supply and the like, which generally need to be separately powered, so that the system is complicated in wiring, huge in size and certain in potential safety hazard. For this reason, this disclosure proposes integrating universal meter interface, direct current power interface (for example, 5V,12V DC), and electric welding table interface in the corresponding interface of integral type teaching experiment device to eliminate the needs of supplying power for each above-mentioned subassembly alone, and overcome the shortcoming such as wiring complicacy, mess, space occupation is big when using.
