Problems solved by technology

The motor operation management devices currently used in the market only have protection and control functions, and can only protect the motor's loading status. Load analysis and energy efficiency data, resulting in waste of a lot of energy consumption of electric motors
In addition, reasonable data cannot be provided according to the load situation, resulting in the inability to use the motor reasonably, which is also the cause of energy waste

Embodiment Construction

[0014] The structural principle of the present invention will be described in detail in conjunction with the accompanying drawings.

[0015] A motor operation management device, its structure and working principle see figure 1 , the conventional high-precision, high-linear precision current / voltage isolation transmitter TA2311 / TV31D (Shandong Zibo Yuanxing Company) enters the synchronous sampling analog-to-digital converter AD7606 (ADI Company of the United States) through the secondary transmission of current and voltage. The calculation of the sampling value, the data reflecting the actual operating status of the motor enters the ADSP processor ADSP-BF518 (ADI company in the United States) through the SPI bus, and the data processing software of the ADSP processor performs data judgment and analysis, and stores the effective operating data to the outside The data memory SDRAM-MT48LC32M16A2 (micron company in the United States) is to be analyzed and called, and the data resul...

Abstract

The invention relates to a motor running management device. A synchronous sampling analog-to-digital converter calculates by a current / voltage isolation transmitter through the secondary transmission of current and voltage, running data is sent into an ADSP (advanced signal processing) processor by an SPI (serial peripheral interface) bus and is analyzed by the ADSP processor, the computed and analyzed data is transmitted to an external data storage through 40 waveform points continuously recorded by wave sampling each week, and the data obtained by the ADSP processor is uploaded and displayed through a communication chip by a communication method and an LCD (liquid crystal display) screen. The motor running management device is suitable for the analysis of running energy efficiency, prewarning of faults, control and protection of low-voltage motors, is especially suitable for occasions with high utilization rate of motors, on-site buses and computer networking systems, and is capable of replacing various types of widely applied existing motor protection controllers.

Description

technical field [0001] The invention relates to a motor operation management device, in particular to an energy efficiency analysis management controller for a three-phase AC asynchronous motor. Background technique [0002] At present, the electricity consumption of motors accounts for more than 40% of the total electricity consumption of countries in the world and more than 60% of industrial electricity consumption. According to statistics from the United States and the European Union, the power consumption of motors accounts for about 42% to 50% of the total power consumption; the power consumption of three-phase asynchronous motors accounts for about 90% of the total power consumption of motors; The number is more than 95%, accounting for about 50% of the total power consumption of the motor. Electric motors are widely used in all aspects of the national economy, and the phenomenon of energy waste is relatively common. All countries in the world attach great importance ...
