For a wiper system including a wiper motor with 5 ports, if the wiper motor (i.e., the wiper motor with 5 ports) is not connected with Chang Zheng ports, automatic counting and automatic resetting cannot be performed, an infrared counter and manual resetting can only be externally added, and the counting and resetting of the scheme are inaccurate and poor in operability. In order to ensure that the wiper motor with 5 ports automatically counts and resets, the means adopted at present are as follows: the Chang Zheng port is directly connected with the high-speed terminal or the low-speed terminal, namely, the normal port wiring is manually adjusted by an operator when the speed gear of the wiper motor is switched every time, the Chang Zheng port is connected with the positive pole electricity of the high-speed terminal when the high-speed gear works, and the Chang Zheng port is connected with the positive pole electricity of the low-speed terminal when the low-speed gear works.
