Title:
CONTROL SYSTEM FOR ELECTRICAL CONTROL PACK
Document Type and Number:
WIPO Patent Application WO/2021/196581
Kind Code:
A1
Abstract:
A control system for an electrical control pack (20). The control system comprises: an electrical control pack (20) for outputting a driving signal to an inductive load (10); a first switch (30), wherein a first end of the first switch (30) is connected to the inductive load (10), a second end thereof is connected to the electrical control pack (20), and the first switch is used for connecting the inductive load (10) to the electrical control pack (20) when the electrical control pack (20) is inserted into a machine body, and for disconnecting the inductive load (10) from the electrical control pack (20) when the electrical control pack (20) is unplugged from the machine body; a communication board (70) located in the machine body and used for communicating with the electrical control pack (20); and a third switch (80), wherein a first end of the third switch (80) is connected to the communication board (70), a second end thereof is connected to the electrical control pack (20), and the third switch is used for connecting the communication board (70) to the electrical control pack (20) when the electrical control pack (20) is inserted into the machine body, and for disconnecting the communication board (70) from the electrical control pack (20) when the electrical control pack (20) is unplugged from the machine body, and when the electrical control pack (20) is unplugged from the machine body, the turning-off time of the third switch (80) is earlier than the turning-off time of the first switch (30), such that a sparking phenomenon occurring and there being a risk of electric shock when the electrical control pack (20) is unplugged from the machine body can be avoided.
