Abstract
The present invention proposes the rotating speed and rate measuring method of motor.MCU module is sent to by data acquisition unit by the way that the Distance-sensing signal of motor, light-sensing signal and supply frequency are tracked into signal, key cell is to MCU module input data signal, key cell transmits mutually signal with MCU module and data storage communication module simultaneously, and the data of the acquisition of MCU module are shown by display unit.The MCU module of the measuring method is core, complete to key cell, display unit, data acquisition unit control, and data storage communication module data transmitted in both directions.The method has intellectual monitoring high precision, simple structure, operational, practical advantage.Suitable rotating speed and revolutional slip measuring method as motor is used.
Description
Technical field
The present invention is to provide the measuring method of ship machine field, the specifically rotating speed of motor and rate is surveyed
Amount method.
Background technology
Working condition of the motor in vessel motion occupies critical positions.Can motor high efficiency, the operation of stabilization
It is an important step of debugging process.In practical operation, by the inclined of the rotating speed of visual observations motor and revolutional slip
Difference is difficult to, and the load of motor can only also be adjusted according to the size of electric current, in addition, there is also some pump groups existing
Unexpected separating brake in start-up course, rotating speed is too low, and a series of problems, such as current value is excessive, conventional meanses cannot record motor in mistake
The data dynamic change of load process.
At present, shown according to marketing texts, in terms of motor speed and revolutional slip analysis and test, in marine vessel applications neck
Domain or blank, rotating speed of the common rotational speed detector of in the market generally only to motor are tested, but to motor
Revolutional slip and the comprehensive professional measurement analysis device of curve data analysis neither one.Therefore, the rotating speed of ship motor,
Revolutional slip and curve data dynamic change read and the problem of analysis is badly in need of solving.
The content of the invention
In order to solve the problems, such as rotating speed and the revolutional slip measurement of ship motor, the present invention proposes the rotating speed of motor
And rate measuring method.The method is read by the rotating speed of actual motion state and the data of revolutional slip to marinemotor
Take, so as to the revolutional slip to motor is analyzed.Solve the technical problem of rotating speed and the revolutional slip measurement of ship motor.
Solving the technical solution adopted in the present invention is：
The Distance-sensing signal of motor, light-sensing signal and supply frequency tracking signal send MCU to by data acquisition unit
Module, key cell is to MCU module input data signal, and key cell is simultaneously mutual with data storage communication module with MCU module
Delivery signal according to legend, the data of the acquisition of MCU module are shown by display unit.
The MCU module of the measuring method is core, is completed to key cell, display unit, data acquisition unit
Control, and data storage communication module data transmitted in both directions.
Good effect, the method is sent to MCU moulds by the current signal that motor occurs by data acquisition unit
Collected information is carried out high-precision algorithm and is filtered by block, MCU module, and the data after treatment are shown and painted
Koji-making line is easy to observe and is analyzed to display module.Meanwhile, MCU by the data of change according to monitoring the time period carry out storage and
Communication, transfers data to host computer.At the appointed time, revolutional slip deviation is excessive or turn up less than requiring when, according to
Alarming value is set, sound and light alarm prompting has been sent, the operation of load adjustment and correlation can have been carried out according to prompting, realized pump group
The normal data monitoring started with stable operation.With intellectual monitoring high precision, simple structure, operational, practical is excellent
Point.Suitable rotating speed and revolutional slip measuring method as motor is used.
Brief description of the drawings
Fig. 1 is measurement apparatus entire block diagram.
In figure, 0. motor, 1.MCU modules, 2. key cell, 3. data acquisition unit, 4. display unit, 5. data deposit
Storage communications module.
Specific embodiment
According to the figure, the Distance-sensing signal of motor 0, light-sensing signal and supply frequency tracking signal pass through data acquisition
Unit 3 sends MCU module 1 to, key cell 2 to MCU module input data signal, key cell simultaneously with MCU module and number
Signal is transmitted mutually according to storage communications module 5, and the data of the acquisition of MCU module are shown by display unit 4.
The MCU module of the measuring method is core, is completed to key cell, display unit, data acquisition unit
Control, and data storage communication module data transmitted in both directions.
The operation of the present apparatus：
The power switch of the device is connected, MCU module is powered, after realizing startup self-detection, the initial of display unit can be observed
Change state, motor parameter, the Distance-sensing or light level and supply frequency of data acquisition unit are set by key cell
After the connection of Monitoring Data line, when running whne motor start-up and normally, after MCU modules are by the data preparation of data acquisition unit,
While carrying out data storage and communications module transmission, the change curve of revolutional slip and rotating speed will be also presented by display unit
On LCDs, and then data analysis and relevant issues are processed.
