Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to demonstration and teaching of an Internet of Things control system, in particular to an Internet of Things control system demonstration prop. Background Art
[0002] With the rise of IoT technology, more and more colleges and universities have begun to offer IoT-related majors, but traditional IoT teaching aids use computers for simulation or rely on large IoT test benches, which means that students cannot conduct experiments anytime and anywhere. In addition, when sales staff and engineers in the IoT industry demonstrate to customers or conduct experiments during corporate R&D, large devices are inconvenient to carry and operate, and small devices may not be able to adapt to a variety of application scenarios or scenario function expansion.
[0003] After the switch components are soldered to the circuit board, due to their own process reasons and the positional offset error caused by the welding process, the switch buttons of the demonstration props that use a large number of switch components will be irregularly arranged after the overall assembly, and will not be arranged according to the original design layout. This will affect the demonstration operation, the overall aesthetics of the product, and the assembly of the circuit board and the casing. In addition, if a switch with light is used, its structure is relatively complex, including the switch button structure, the lamp bead structure, and the welding base structure. After being soldered to the circuit board, it cannot be guaranteed to be neatly and standardizedly arranged, and there is random deviation. This will have an adverse effect on both operation and demonstration. Summary of the invention
[0004] The existing IoT demonstration props need to consider the size of the props, and they need to be convenient for engineers or demonstrators to operate, so the demonstration props use switches with lights to integrate input, i.e. switch signals, and output, i.e. lighting effects. However, when using components such as switches with lights, it is also necessary to avoid the switch buttons from being skewed, which affects the operation, assembly, and aesthetics.
[0005] A demonstration prop for an Internet of Things control system includes a demonstration scene schematic sticker, an upper cover, a bottom cover, a PCB connector, and a circuit part. The PCB connector is used to install the circuit part and the bottom cover on the upper cover.
[0006] The circuit part includes a power input interface and several demonstration units. The demonstration units are arranged and connected in combination according to the demonstration purpose. The demonstration units can interact with each other. Each demonstration unit includes a voltage regulator chip, a microcontroller, a memory, and a lighted switch. The microcontroller is connected to the memory and the lighted switch. The power input interface supplies power to the lighted switch and the voltage regulator chip, and the voltage regulator chip provides working voltage to the microcontroller and the memory.
[0007] Each lighted switch has a button on the upper cover that transmits the pressing force. When the user presses the button on the upper cover, the pressure is firstly contacted, and then the pressure is transmitted to the lighted switch to form pressure.
[0008] Preferably, the upper cover includes a circuit board supporting structure for placing the circuit board, and also includes a lower cover mounting structure, and stickers schematically showing the demonstration scene are affixed on the outer surface of the upper cover.
[0009] Preferably, the microcontroller uses a chip of CH571F. The microcontroller stores the corresponding program for running the function of the demonstration unit. The demonstration function of the demonstration unit will be different according to the demonstration purpose, so the program of each microcontroller may be different.
[0010] Preferably, the lighted switch adopts model K6-6272S01 produced by Hanrong of South Korea.
[0011] Preferably, the button on the upper cover adopts a cantilever button structure, and the middle of the button is hollowed out. The middle of the button is hollowed out so that the light emitted by the corresponding lighted lamp bead can better pass through and reach the sticker after assembly.
[0012] Preferably, on the demonstration scene schematic sticker, there is a corresponding printed pattern logo at the position of the upper cover button, and the position covering the hollowed-out position of the button serves as a light-diffusing plate corresponding to the lamp beads of the illuminated switch.
[0013] Compared with the prior art, the advantages are: a single demonstration prop device is small in size and easy to carry. The lighted switch simulates the switch signal and lighting function device, which saves the demonstration prop volume, simplifies the necessary components of the Internet of Things control system, and facilitates personnel demonstration and experiment. The cantilevered button has a simple structure and can cover the irregular position arrangement of the lighted switch after assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The purpose of the demonstration scene schematic sticker is to reflect the IoT application scenario to be simulated through the printed pattern on the sticker. For example, the sticker can print the architectural drawings of each room and corridor for the office building scene, and the architectural structure drawings of the parking spaces and driveways can also be printed to represent the parking lot scene. In addition, at the corresponding upper cover button, that is, the position of the corresponding lighted switch, the function of the corresponding position is indicated by printing lamps or switch patterns. Of course, the same position can also represent lamps and switches at the same time. After all, the function of the lighted switch is to combine the switch signal and the light of the lamp into one. The design of the printed architectural structure drawings on the sticker needs to leave corresponding space for the corresponding position of the button.
[0019] like Figure 1 As shown, a demonstration prop has multiple demonstration units. After the overall demonstration prop is assembled, each circuit demonstration unit has a corresponding cantilever button and a corresponding pattern of the demonstration scene sticker. The purpose of the demonstration can be a research and development operation demonstration, and multiple demonstration units are arranged and combined according to the requirements of the R&D personnel. The purpose of the demonstration can also be based on the specific engineering implementation scene architectural drawings to be presented by the demonstration scene stickers, and the demonstration unit planning and arrangement made according to the drawings.
[0020] The circuit part in each demonstration unit can be self-contained. The microcontroller recognizes the switch signal of the light switch and outputs the control parameters of the light of the lamp beads. The memory stores the demonstration unit program and operation plan. The light switch can generate a switch signal through an external press, and can also output different lighting schemes according to the program and switch signal. Multiple demonstration units can interact and cooperate, that is, the switch signals of other demonstration units can also be collected and used by this demonstration unit. For example, the switch signal of the demonstration unit next to it can also make the lamp beads of this demonstration unit glow.
[0021] like Figure 3 and 4 As shown, the switch with light adopts model K6-6272S01. The factory structure of the switch with light includes a welding base 1, a switch structure 3 on the welding base, a lamp bead 4 on the inner side of the center of the switch structure for emitting light, and a light-distributing plate key structure 5 on the switch structure for transmitting the light of the lamp bead while bearing the key structure.
[0022] like Figure 3 As shown, its structural characteristics lead to uncontrollable position deviation in the dotted ellipse circled in the figure: welding position 2, the matching point of switch structure 3 and welding base 1, and the snap assembly point of light-diffusing plate button 5 and switch structure 3, resulting in the problem of irregular arrangement affecting the demonstration as described in the background technology.
[0023] There are two implementation methods that can be used to solve this problem. One is that the upper cover button is higher than the upper surface of the light diffuser button 5, and it is ensured that the upper cover button can be pressed to squeeze the light diffuser button. This method directly uses the light switch K6-6272S01 to reduce the assembly process.
[0024] Another way is to remove the light-diffusion plate button directly from the lighted switch, such as Figure 4 The light-diffusing plate button and switch structure are snap-fitted, which is easy to disassemble. Then the upper cover button is higher than the upper surface of the switch structure, which also ensures that the upper cover button can be pressed to the switch structure. This method can save space and volume for the overall demonstration prop structure and is more convenient to carry.
[0025] like Figure 2 As shown, the upper cover button adopts a cantilever structure. One implementation method is to use a hollow U-shaped ring structure on the upper cover, so that the middle solid part of the U-shaped structure becomes the button. This method can ensure that there is no raised structure on the upper cover surface, which is convenient for pasting demonstration scene schematic stickers.
[0026] The hollow in the middle of the cantilever button on the upper cover is to allow the light beads of the light switch underneath to shine on the demonstration scene sticker without loss.
[0027] The demonstration scene stickers can be made of light-dispersing and light-transmitting materials. The color can be transparent or white, which is easy to transmit light. After printing the demonstration scene schematic pattern, the hollowed-out position can be illuminated by its own material and color without spraying other colors. At the corresponding button position, a simulated IoT product type appearance pattern can be used to indicate whether the button here is a lamp, switch, or a combination of the two. It can also be expressed in words, so that the function of each demonstration unit of the demonstration props is clearer.
