Title: WIRELESS VOLTAGE-STABILIZING AND CURRENT-LIMITING CIRCUIT FOR EXERCISE BICYCLE THAT CAN GENERATE ELECTRICITY
Abstract:
A wireless voltage-stabilizing and current-limiting circuit for an exercise bicycle that can generate electricity, comprising: a power supply, a first control chip (U1), a second control chip (U2), s first resistor (R1), a second resistor (R2), a third resistor (R3), a triode (VT1), a current acquisition network (P1), a voltage acquisition network (P2), and a wireless transmission network (P3). The wireless voltage-stabilizing and current-limiting circuit for an exercise bicycle that can generate electricity uses the technical solution of paralleling a voltage stabilizer, a single chip microcomputer, and wireless transmission. By means of an on-chip analog-to-digital converter on the single chip microcomputer and a peripheral circuit thereof, voltage-stabilized output current and voltage values are acquired. When the voltage-stabilized output voltage is constant and the current reaches a limiting condition, the single chip microcomputer controls the output of the voltage stabilizer by regulating the working state of a voltage-stabilizing chip. In addition, a wireless system can receives current-limiting data sent from a wireless control end, transmits the data to the single chip microcomputer in a timely manner, and updates the current-limiting condition, thereby implementing limiting of output current of the voltage stabilizer and limiting of current parameters by means of wireless transmission.
