Description

TECHNICAL FIELD

[0001] The present application relates to the field of motor driving, in particular to a multi-channel driver detection method. BACKGROUND

[0002] Currently, the fan and pump motors used in weapon equipment have been upgraded from traditional DC motors to brushless DC motors. Brushless DC motors have higher efficiency conversion and can reduce ineffective heating, making them more suitable for long-term operation. The mechanical wear of carbon brushes is eliminated, providing higher service life. However, brushless DC motors require electronic commutation. To ensure miniaturization and lightweight upgrading, the current demand is to have one driver simultaneously drive multiple motors.

[0003] The brushless DC motor driver used in the fan or pump equipment on the current military vehicle is one-to-one control. One controller drives multiple motors has become popular, but it is mostly one-to-one detection, which cannot achieve one-to-many function detection. The detection efficiency is low, and the detection test method does not match the actual use scenario. Therefore, a multi-channel driver function detection method needs to be developed. SUMMARY

[0004] The purpose of the present application is to provide a multi-channel driver detection method, comprising the following steps:

[0005] 1) Connect the driver output end with the Hall sensor and phase line of each motor in turn; and connect a fault light and a single-pole double-throw switch between the driver and each motor to be detected;

[0006] Connect the driver input end with a button switch and a rectifier module in turn;

[0007] 2) Turn on the button switch, convert the mains into a driver voltage using the rectifier module, then input it to the driver through the driver power input plug to power the driver, so that the driver generates a motor control signal;

[0008] 3) Turn on each single-pole double-throw switch to transmit the motor control signal generated by the driver to the motor to be detected;

[0009] The motor to be detected performs forward and reverse rotation and shutdown operation according to the motor control signal;

[0010] During the operation of the motor to be detected, determine whether the fault light is on. If there is a fault light on, the controller is faulty.

[0011] Further, the rectifier module converts the mains 220VAC into a 24VDC driver voltage.

[0012] Further, the driver output end is connected with the Hall sensor and phase line of at least two motors.

[0013] The technical effect of the present application is self-evident. The present application can realize one-to-many function detection and improve the detection efficiency of the driver. BRIEF DESCRIPTION OF DRAWINGS
