Abstract

The invention discloses a torque motor driving turntable parameter testing device, comprising: a liquid crystal touch screen and a control card, wherein the control card comprises a main controller DSP, a CPLD, an off-chip extended memory, a pulse width modified wave driving chip and a communication interface chip; the liquid crystal touch screen is used for inputting and displaying parameters, and is connected with the main controller DSP through the communication interface chip; the communication interface chip is used for realizing the communication between the liquid crystal touch screenand the main controller DSP; the main controller DSP is used for performing controlling operation through the parameters input by the liquid crystal touch screen and outputting a PWM signal for a torque motor; and the CPLD is connected between the main controller DSP and the off-chip extended memory, and is used for storing the data of the main controller DSP into the off-chip extended memory, orinputting the data stored in the off-chip extended memory to the main controller DSP through the CPLD. The invention provides a turntable parameter testing device realized by a method using the liquidcrystal touch screen.

Description

Technical field [0001] The invention relates to the field of control technology, in particular to a torque motor driven turntable parameter testing device. Background technique [0002] The traditional parameter test method of torque motor drive turntable is realized by using the hardware of the control system and the test software. However, due to hardware limitations, the parameter curve cannot be displayed in real time, and the operation is not intuitive. In addition, during the commissioning of the turntable, load changes often occur, and parameter changes need to be monitored frequently. For the convenience of debugging, we have designed a turntable parameter test device. [0003] The present invention proposes a turntable parameter test device realized by using a liquid crystal touch screen method. Summary of the invention [0004] The present invention aims to overcome the defects of the prior art and provides a turntable parameter test device realized by the method of a li...
