Brushless motor control device and method, and application

Abstract

The invention discloses a brushless motor control device and method, and application. The method comprises the following steps: step 1: a command is issued to close tarpaulin through a signal indicating unit, a microprocessor receives the command and controls a driving unit to control a brushless motor to forward rotate, and the tarpaulin runs in the cover closing direction; step 2: the microprocessor always monitors the position of the tarpaulin; step 3: when the microprocessor detects a tarpaulin in-position signal, the microprocessor controls the brushless motor to be inverted for 30-50 msthrough the driving unit; and step 4: the position of the tarpaulin is processed and judged by the microprocessor; and when the tarpaulin is completely closed, the current and time data detected by ananti-cheating unit is transferred to a muck vehicle management platform by a communication and alarm output unit through the Beidou satellite network for check.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a brushless motor control device, method and application. Background technique [0002] The muck transportation of construction projects is generally performed by special large-scale engineering vehicles, referred to as: muck trucks. In the past, although our country had clear standards and regulations on muck transportation methods and vehicles, most muck trucks are generally used in Working at night will inevitably reduce the intensity of supervision. Therefore, many muck transport vehicles are basically seriously overloaded and overspeeded, resulting in violations of rules and regulations such as muck throwing and dust flying along the way, which seriously affects our life, safety, and environmental pollution. bring many negative effects.

[0003] The tarpaulins of muck trucks in the prior art are all driven by DC motors, but the manufacturing process of DC motors is complicated and the production cost is high

Difficult to maintain

The reliability is poor, so some manufacturers use brushless motors instead of DC motors, but the controllers of brushless motors are quite different from those of DC motors, so there is an urgent need for a brushless motor control device
