Problems solved by technology
At present, there are many types of mechanical building blocks, but none of them can intuitively display the direction and magnitude of the force at each structural position. Therefore, although children can find stable structural forms when assembling structures with such toys, they cannot It is impossible to make quantitative analysis and comparison between structures, and it is impossible to improve the structure in terms of the direction and magnitude of the force.
Although software-based mechanical structure building programs or games can display various force analysis information through images, they lack the experience of physical operations, and it is difficult to establish a reliable and stable understanding of the volume and actual strength of various structures.

Embodiment Construction
[0012] The present invention will be further explained below in conjunction with specific examples.
[0013] Such as figure 1 As shown, a learning teaching aid for visually displaying the magnitude and direction of the force, including (1) a rod 1 with a built-in 51 single-chip microcomputer or an embedded control system with the same performance, and a row of RGB three-color LED lamp beads 3 built in the rod body; (2) ) There are connectors 2 on both sides of the rod, which can be connected or built; (3) The connectors at both ends of the rod are ring-shaped structures, and there are two RFP602 film pressure sensors inside. The sensors are connected to the control board inside the rod and can sense Compressive and tensile forces at both ends of the rod.
[0014] Such as figure 2 As shown, the flow of the control system is: when the two ends of the rod are under pressure, the resistance of the pressure sensor 4 inside the connector at both ends of the rod decreases, and the...

The invention discloses a learning teaching aid for visually displaying the force bearing size and direction and a control system thereof. With application of the structure, the force bearing direction and force bearing size information of each structure rod can be visually displayed so that the clearer and quantitative understanding of each structure form can be quickly established for the student to understand the advantages and the disadvantages of different structures and perform targeted improvement. According to the scheme, the force bearing size and force bearing direction information is visually presented and the experience of actual operation is reserved so that the system has high extensibility, the structure of the related scheme can be extended to the direction of transmissionstructure building blocks and thus the scheme has high educational meaning and market value.
Description
technical field [0001] The invention relates to the field of embedded development technology and pressure sensing technology, in particular to a learning teaching aid and a control system that visually displays the force magnitude and direction. Background technique [0002] Microcontroller Embedded Development and Pressure Sensing. The embedded development technology used in the scheme is currently very mature. The pressure sensing technology uses a thin-film pressure sensor. This technology has the characteristics of small size and high precision, and is suitable for installation in various structural connectors. At present, there are many types of mechanical building blocks, but none of them can intuitively display the direction and magnitude of the force at each structural position. Therefore, although children can find stable structural forms when assembling structures with such toys, they cannot It is impossible to make quantitative analysis and comparison between str...
