In the popular LabVIEW bacilli A4 car windscreen production application

In car wiper motor production, how online testing, motor performance and motor vibration quantity, testing data storage and bar code printing? Engineers use of National Instruments company simulation acquisition card and digital acquisition card, match with vibration sensor, magnetic powder brake and torque sensor, encoder and the controlled voltage stabilizer and develop a reliable, economic, and flexibility of the PC based on the motor test system.
Volkswagen company produces the bacilli car wiper motor for permanent magnet A4 type dc motor and motor working voltage for 13 V rated power output at 40 W, motor lead for 4 wire, high speed, low speed respectively the end, reset end and grounding terminal. Bring their own wiper motor reducer, gear box internal a switch, when reset termination have 13 VDC voltage, the motor will begin slowly rotating, when the worm gear protruding point to rotating joints reset point, slowing the reset the switch, motor armature is short circuit, motor braking energy, realize the wiper reset, and power supply open circuit.
According to the technical requirements of the project, the need to test motor load conditions in some of the low speed high speed, high speed, high speed difference low current, voltage, motor reset Angle, and make motor stops in the "load Angle", in addition to rotary union test motor under the condition of no-load in vibration.
The choice of software development
In the world of several excellent industrial control configuration software was analyzed and compared, vale company of foreign technical personnel suggested that Shanghai valet car windscreen wiper motor system Co., LTD LabVIEW software to develop with special equipment, they think, "the most outstanding LabVIEW software". And according to the Shanghai valet car windscreen wiper motor system Co., LTD. The actual use of the production equipment, the engineers in LabVIEW, VB and other more in the industrial control configuration software is discussed, finally choosing LabVIEW software.
They choose LabVIEW software is the main reason for the LabVIEW software programming because of easy, friendly interface, powerful, stable performance, short development cycle. In addition, the Shanghai valets motor car windscreen wiper system Co., LTD. Had LabVIEW software development using imported equipment, the engineer of the training of LabVIEW software, therefore, the engineers to fiber optic rotary joint LabVIEW software system are familiar.
