STM 32-based low-power multipath wireless synchronization type oar-force acquisition system

The invention discloses an STM 32-based low-power multipath wireless synchronization type oar-force acquisition system, which comprises a plurality of oar-end acquisition devices, and an information acquisition box. The oar-end acquisition devices are arranged at the end portions of all oars and are used for acquiring the pulling forces of oars and the torsional forces of oars. The information acquisition box is arranged on a canoe. Each of the oar-end acquisition devices is composed of an oar pulling force sensor, an oar torsional force sensor, a lithium battery B1, a differential amplifier circuit, an oar-end wireless communication module and an oar-end microcontroller U3. The information acquisition box comprises an information acquisition box wireless communication module, an information acquisition box microcontroller, a USB-UART bridger U7, a lithium battery B2 and a voltage-stabilizing chip. According to the technical scheme of the invention, the STM 32-based low-power multipath wireless synchronization type oar-force acquisition system has the advantages of low power consumption and better training effect. Based on the system, the problem that the existing oar-end wired communication system of a canoe is low in accuracy and poor in reliability can be solved.
