Embodiment 1

[0025] refer to figure 1 , a power monitoring method, comprising the steps of:

[0026] S1. Measure the initial battery power Q in the initial state of the motor, then put the motor in a no-load state, and conduct n times of no-load tests on the motor, where n is a positive number greater than or equal to 1.

[0027] S2. During each no-load test, make the motor continue to work at the speed ω for a time t until the battery power of the motor is 0, and measure the vibration frequency f of the motor at the speed ω at the same time.

[0028] S3. Calculate the rotational energy consumption E of the motor for the continuous working time t at the rotational speed ω in each no-load test, and thus obtain the power consumption W of the motor vibration during the continuous working time t of the motor at the rotational speed ω.

[0029] S4, according to the motor vibration power loss W, motor vibration frequency f and continuous working time t in each no-load test calculated in step S3...

Abstract

The invention provides an electric quantity monitoring method and device, wherein a relation curve of a motor vibration loss electric quantity W, a motor vibration frequency f and continuous working time t is obtained by monitoring a motor in a no-load state, and the electric quantity lost by the vibration of the motor in the working process is obtained according to the relation curve of the vibration frequency, the continuous working time and the motor vibration loss electric quantity W, the motor vibration frequency f and the continuous working time t when the motor load works. The electric quantity monitoring method and device can accurately monitor the vibration energy loss of the motor in real time, and can provide powerful data support for reasonably utilizing the vibration energy of the motor.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a method and device for monitoring power consumption due to vibration. Background technique [0002] Over the past 100 years, developed countries have completed industrialization successively, consuming a large amount of natural resources on the earth, especially energy resources. At present, some developing countries are entering the stage of industrialization, and the increase in energy consumption is an objective necessity of economic and social development. As the largest developing country in the world today, our country is also facing a huge loss of natural resources while achieving rapid economic development. Therefore, green environmental protection, energy conservation and emission reduction have become the focus of attention of the Chinese government, social organizations and groups. . [0003] Cars have become a must-have item for current families, and the u...
