Power electric cable hoist ( current, voltage and power ) measurement process

Electric cable hoist detection of power transformer 2 ton chain hoist analog measured parameter , and sent to the transmitter power, transmitter power shift from the analog signal will be measured as 0 ~ 5V voltage signal , ratchet lever chain hoist and then through the isolated analog input terminal board into the IPC, and finally by the display the measurement results are displayed visually 2 ton chain hoist, and record the results. Brake has been a decline in the amount of electric cable hoist test of a problem , we pioneered the use of laser distance sensor in the industry to measure the amount of braking decline , the specific detection process is : Laser distance sensor via an asynchronous serial interface (RS232C) and IPC to communicate in real time and displays the position of the weight on the screen ; the test, issued a " stop" signal to the hoist by the IPC electric cable hoist, the motor stops running ; according to the storage location of the initial weight at this time ; the motor stops running, 2 ton chain hoist due to gravity , weight also fell 2 Ton Electric Chain Hoist, then the CPU will continue to send the value of laser distance sensor reading in three consecutive.

When time ( or within the time specified ) weight position to achieve approximately equal values read request , indicating that the weight has stopped falling ; weights Electric Chain Hoist And Trolley and weight position last position value will be subtracted from the initial read , that get electric hoist decline in the amount of braking . Other 2 ton chain hoist ( such as lifting speed , car speed, etc. ) of the measurement, and the measurement is similar to the amount of brake decline , but at the same time recording the movement of displacement test of time electric cable hoist, and then the displacement and movement time was compared to the speed value. 2.7 overall design and control software required by the system function, you can get the following sub-module software 20 Ton Chain Hoist architecture .
