Electric hoist energy efficiency remote acquisition system and method

Abstract

The invention discloses a system and a method for remotely acquiring energy efficiency of an electric hoist, wherein the system and the method belong to the electrical and automation fields. The method comprises the steps of for aiming at one operation period, calculating supplying energy of an electric hoist lifting mechanism for finishing a lifting action through a master control module; acquiring a lifting height through a height measurement module; acquiring a load weight of the electric hoist; calculating an effective energy which is generated by the electric hoist in finishing the lifting action through the master control module according to the lifting height and the load weight; calculating an energy efficiency value of the electric hoist through the master control module accordingto the supplying energy and the effective energy; and transmitting the energy efficiency value to a server through a GSM communication module. The system and the method settle a problem of low testing efficiency caused by electric hoist energy efficiency value acquisition through field testing. The system and the method realize effects of increasing the number of the tested electric hoists in thesame time period, and improving automation degree and efficiency in energy efficiency acquisition.

Description

technical field [0001] Embodiments of the present invention relate to the field of electricity and automation, and in particular to a system and method for remote collection of energy efficiency of an electric hoist. Background technique [0002] Electric hoists, as special equipment for lifting machinery, are widely used in the material handling industry because of their convenient manufacture, simple installation, simple maintenance, low price and flexible operation. According to incomplete statistics, at the end of 2016, there were more than 450 electric hoist manufacturers in my country, with an annual output of more than 1 million units, and the electric hoist market in my country still maintained a relatively high average growth rate. Due to the large number of electric hoist users in my country, the annual energy consumption of electric hoists is huge. At present, the total installed capacity of electric hoists in my country is about 580 million kilowatts. It can be s...

Problems solved by technology

[0004] At present, in actual use, the load and lifting height of the electric hoist will change each time. To test the energy efficiency value of the electric hoist under actual working conditions, it is necessary to manually measure the load weight and calibrate the test system after changing the load, resulting in cumbersome testing. , The degree of automation of the test process is not high
