Abstract
The invention discloses a dynamic pressure motor parameter monitoring system and monitoring method. The dynamic pressure motor parameter monitoring system comprises a parameter test gathering module, an intelligent control module, a dynamic pressure motor power supply module, a data display module and a data storage module. The dynamic pressure motor parameter monitoring system and monitoring method are capable of testing and displaying the working parameters of one or more dynamic pressure motors in real time, and the working state of the dynamic pressure motor is judged precisely through dynamically comparing the dynamic pressure motor parameters.

Description
Technical field
The present invention relates to a kind of method of dynamic pressure parameter of electric machine monitoring system and monitoring, particularly there is the high precision, high reliability of robotization real-time testing and demonstration, intelligent trouble detection and processing, history data store and query function and a method that can unattended dynamic pressure parameter of electric machine monitoring, belong to dynamic pressure motor observation and control technology field.
Background technology
Dynamic pressure motor is the heart element of high-accuracy mechanical formula inertia type instrument, it is the position that relies on air film that between the rotor of High Rotation Speed and stator, atomic little gap forms or liquid film accurately to stablize rotor, under state contactless, that rub without rigid body, work, thereby realize high precision, long time continuous working and long-life requirement of instrument, this precision for inertia type instrument and reliability play vital effect.
At present, the monitoring of the dynamic pressure parameter of electric machine is mainly that power, the testing current equipment by directly connecting with dynamic pressure motor detects, general a set of testing apparatus can only be monitored the state of a dynamic pressure motor, and whether need to have tester to pay close attention in real time the dynamic pressure parameter of electric machine normal, expend a large amount of manpower and materials.The running-in that often needs to switch on for a long time of the characteristic such as long-life and reliability of dynamic pressure motor is examined it, and what therefore have Real-Time Monitoring, storage and fault handling can unattended dynamic pressure parameter of electric machine monitoring method just seem very necessary.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of dynamic pressure parameter of electric machine monitoring system and monitoring method, can carry out Real-Time Monitoring and there is automatic protection functions many dynamic pressure motors simultaneously.
Technical solution of the present invention is:
A kind of system of dynamic pressure parameter of electric machine monitoring comprises: parameter testing acquisition module, intelligent control module, dynamic pressure motor power module, data disaply moudle, data memory module;

Data memory module receives the dynamic pressure parameter of electric machine, dynamic pressure parameter of electric machine judged result and the fault dynamic pressure motor situation of intelligent control module transmission and stores, and carries out the inquiry of historical data for user;
Parameter and the alarm of the dynamic pressure motor that data disaply moudle sends the intelligent control module receiving show.
Based on a monitoring method for dynamic pressure parameter of electric machine monitoring system, comprise that step is as follows:
(1) dynamic pressure motor powers up starting;
(2) parameter of Real-time Collection dynamic pressure motor, and the parameter of dynamic pressure motor is converted to digital quantity, the parameter of described dynamic pressure motor comprises the electric current of dynamic pressure motor, active power, supply voltage, supply frequency, adds up conduction time;
(3) parameter of the dynamic pressure motor to digital quantization in step (2) is stored, is shown and relatively judgement, and relatively the step of judgement is as follows:
