Technical Field

[0001] The utility model relates to the technical field of science and technology museum exhibits, in particular to an electronic control system for an interactive science popularization exhibit for multi-person collaborative work. Background Art

[0002] Multi-person collaborative interactive exhibits are a type of science and technology museum exhibits. Regarding the control system of multi-person collaborative interactive exhibits, the principle of existing exhibits is as follows: Three audiences respectively operate a force feedback device to simulate one-dimensional linear motion. The three people simultaneously complete an interactive process of a small ball moving from the starting point to the end point in a multimedia-simulated pipeline in a three-dimensional environment. The technical solution is as follows: Three computers form a local area network. Each computer is connected to a force feedback device, a voice recognition system, and a sound playback system. In a three-dimensional system environment, the three audiences cooperate with each other through voice and sound to control the movement of the small ball by operating the force feedback device. The control method is to form a network, enabling each participant to operate the force feedback device to control the small ball, and the position of the small ball is feedback through the screen. The three participants jointly achieve it through the cooperation of the voice microphone and sound feedback. The system is relatively complex, the signal transmission failure rate is relatively high, and the cost of the entire control system is also relatively high. In addition, the entire system is actually a multimedia game, and it is relatively weak in spreading knowledge of cooperation concepts and teamwork spirit. Moreover, for low-age and high-age people, the universality is not high. Content of the Utility Model

[0020] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] As Figure 1 shown, an electric control system of an interactive popular science exhibit for multi-person collaborative work includes an exhibition stand and a self-powered indicator button 1, a rope 2, a lamp panel module 3, a color sensor 7, a ring 5 and an orange ball 6 arranged on the upper surface of the exhibition stand. A plurality of lamp panel modules 3 are placed in the middle area of the exhibition stand. There are multiple ropes 2, and one end of the rope 2 is tied to the ring 5. The ring 5 can move on the tabletop under the cooperation of multiple ropes 2. An orange ball 6 is placed in the ring 5, and the other end of the rope 2 extends to the edge of the exhibition stand; the lamp panel module 3 is composed of a sunken small nest bottom plate 8, a lamp ring 4 and a color sensor 7, and the color sensor 7 is arranged at the middle position of the sunken small nest bottom plate 8.

[0022] The surface shape of the exhibition stand of the present utility model is polygonal or circular. In this embodiment, a triangular exhibition stand is given, where there are 3 ropes, enabling three-person interaction. Among them, the number of lamp panel modules 3 on the exhibition stand is 9. The inner groove of the sunken small nest bottom plate is embedded with the lamp ring 4, and an M3 thread is preset at the center position of the bottom plate for facilitating the installation of the color sensor 7. A control circuit board is arranged inside the exhibition stand, and the control circuit board is electrically connected to the button with a lamp 1, the color sensor 7, and the lamp ring.

[0023] A running light for timing is also arranged on the exhibition stand, and the running light is electrically connected to the control circuit board. The duration of the interactive game is such that the number of lit LEDs on the lamp strip gradually decreases as time goes by.

[0024] A voice prompt module is also arranged on the exhibition stand. The voice prompt module is electrically connected to the control circuit board and is used for voice prompting whether multi-person collaborative work has successfully moved the ball to the lit area. As Figure 2 shown, the voice prompt module is an MP3 module and a speaker electrically connected thereto.

[0025] The control circuit board is electrically connected to the power module inside the exhibition stand. As Figure 2 shown, the control circuit board and the electronic components of the exhibition stand are powered by a switching power supply. The front end of the switching power supply is sequentially connected to a contactor, a leakage protector, and an air switch, and the air switch is connected to a 220V AC power supply.

[0026] The control circuit board is a control board based on the STM32F103 series single-chip microcomputer chip, which is used to receive the button function selection signal, detect whether multi-person collaborative work has successfully moved the ball to the lit area, and control electronic modules such as the voice module and the timing running light.

[0027] As Figure 1 shown, there are three buttons with lamps 1, which are respectively used for function selection of the easy, medium, and difficult modes of the interactive popular science exhibit, and the buttons have self-powered indicators.

[0028] The interactive solution for this exhibit is as follows: Three audiences cooperate to complete the task. They each pull one end of a rope, and the other ends of the ropes converge on a ring. A small ball is placed inside the ring. The three people cooperate to pull the ropes to move the ring so that the small ball falls into the designated area on the exhibition stand. Completing a certain number of movements within the specified time is considered successful, otherwise it is not. The functions of this electronic control system are: Select three difficulty levels of easy, medium, and hard through the lighted buttons. A certain number of lighted areas are randomly generated on the exhibition stand. When moving the ring, it is detected and judged by the sensor whether the small ball reaches the lighted area. The success or failure will be recorded and a voice prompt will be issued accordingly.

[0029] The principle of detecting and judging whether the small ball reaches the lighted area through the sensor is as follows: As Figure 4 shown, the lamp board module 3 is composed of a sunken small nest bottom plate 8, a lamp ring 4, and a color sensor 7. The lamp ring is embedded in the sunken small nest bottom plate, and the color sensor 7 is installed at the center of the bottom plate. When the orange small ball falls into the sunken small nest 9, the color sensor 7 can collect the color difference. When the threshold is reached, it is determined that the small ball reaches the designated position successfully. If there is no small ball falling or the small ball quickly slides by, it is judged as unsuccessful, and then it is detected by the control circuit board. In addition, the duration of the interactive game is simulated by a strip of lights around the exhibition stand. As the time decreases, the number of lighted LEDs on the strip of lights gradually decreases.

[0030] The above is the preferred implementation mode of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
