The hardware composition of electric vehicle detection line mainly includes detection, control and display. The electrical signal of each motor and the part that can be used to detect the movement of the motor can be measured. In the display part, some detection information is given by two devices: display and indicator. The following is a detailed introduction to each person.
1. The detection part of the system mainly includes the detection of switching value, analog quantity and pulse quantity. Through the switch input board hy-6110, the switch signal is sent to the computer, such as foot switch and some auxiliary buttons of each detection item. These signals are only in high and low levels. The computer detects and controls the level state of the collected signal.
2. The control part of the system mainly includes the control of motor, cylinder, fixture, indicator light, alarm and other equipment in each station. Install motor vehicle inspection line. It is realized by computer controlling hy-6150 to output switch signal. Because the output signal power of 6150 is small, it is not enough to drive high-power motor equipment. The relay interface board hy-890 is set at the output end of 6150. The output of relay controls the motor and cylinder to realize power amplification and achieve the purpose of microcomputer control.
3. The display part of the system mainly displays the scanning result, prompt information, detection result, judgment standard and judgment result. Among them, the first four stations are given in the form of graphics and numbers through their respective displays, while the second two stations are only equipped with color indicator lights to indicate the detection process and determine the results. This is because the special detection instrument has its own display screen.
