Abstract

The invention discloses a pruning machine speed regulation control method. The pruning machine speed regulation control method comprises that a power supply system is established and started to issue triggering signals; a center processor detects the voltage of the power supply system to determine whether to maintain operation of the power supply system and further to transmit output maintaining signals; a speed regulating trigger button is pressed, and the central processor converts speed regulating signals transmitted by the speed regulating trigger button into electric signals for speed judgment; driving signals are issued after motor position signals are detected to control rotation of a motor; a sampling resistor converts current into voltage signals and inputs the voltage signals into the central processor to control the motor to rotate at a certain ratio or the highest power. Therefore, the pruning machine speed regulation control method can help enter an energy saving mode and achieve a low output power during idle load, and enter a constant-power mode during full load to maintain the operating current of a pruning machining at the highest power, so that the pruning machine is easy to protect and smooth in operation, and the problem of idle load power consumption and protection simplicity of the pruning machine can be well solved.

Description

Technical field [0001] The invention relates to a variable speed control method, in particular to a variable speed control method of a pruning machine. Background technique [0002] Existing pruning machines use ON / OFF switches to directly control the work of the pruning machine, which consumes power in vain when idling, and is not easy to protect due to excessive current when fully loaded. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a variable speed control method for the pruning machine. When no load, it enters the energy-saving mode, the output power is small, and when it is fully loaded, it enters the constant power mode, so that the pruning machine runs at the maximum power and the current is unchanged , Easy to protect, work smoothly, can better solve the problem of no-load power consumption and easy protection of pruning machine. [0004] In order to solve the above technical problems, a technical solution adopte...
