(54) | ANTI-INTERFERENCE APPARATUS AND METHOD |
(57) An interference prevention apparatus and method are disclosed. The interference prevention
apparatus includes: an interference prevention module and a control module, where
the control module is configured to send a working signal to the interference prevention
module; the interference prevention module is configured to receive the working signal,
and control a working state of a first component according to the working signal;
the first component is connected to the control module by using at least one first
connection wire, the at least one first connection wire is divided into at least two
segments by an interference prevention material, and the interference prevention material
is connected to ground; and the interference prevention module is further configured
to send a return current signal to the control module, and the return current signal
flows to the control module through the interference prevention material. A corresponding
interference prevention method is further disclosed. According to the technical solutions
of the interference prevention apparatus and method provided in embodiments of the
present invention, a connection wire between a control module and an interference
prevention module is divided by using an interference prevention material, which reduces
a loop area of a return current signal, and can effectively reduce electromagnetic
radiation interference generated in a circuit at a low cost.
