The invention discloses an anti-interference
repeater based on a
CAN bus, and mainly relates to the technical field of communication equipment. The anti-interference
repeater comprises a shell and an interface; a
relay component, a power supply component, a
signal input component and a
signal output component are arranged in the shell; the
relay component, the power supply component, the
signal input component and the signal output component are connected in series; the interface is arranged on the surface at one side of the shell, and an automatic warning device and a self-luminous layer are arranged at one side of the shell with the interface; the self-luminous layer is made of long persistent phosphors; the
relay component comprises a CPU, a receiving relay unit and a sending relay unit, wherein a photoelectric
isolator is arranged on the sending relay unit; a shielding net cover is arranged on the shell surface, the shielding net cover comprises an insulating layer and a protective layer; the protective layer is made of an acid-alkali
corrosion resistant layer, a heat preservation layer and a wear-resisting layer. The
repeater disclosed by the invention is strong in
interference resistance, long in service life, and capable of guaranteeing the long-time safe and stable operation of the signal transmitting work.
