Diesel engine particulate matter sensor regeneration device and control method thereof

The invention relates to a diesel engine particulate matter sensor regeneration device and a control method thereof. The device comprises a sensor sampling probe and a control module. The sensor sampling probe is used for collecting tail gas carbon dust particles; and the control module is used for regenerating the sampling probe module. The sensor sampling probe comprises an outer side protection piece, an inner side protection piece and a high-voltage electrode; an area between the inner side protection piece and the high-voltage electrode is a tail gas carbon dust particulate matter concentration detection area; one end of the high-voltage electrode is connected with a regeneration ceramic heater; the control module comprises a micro-current measurement module, a controller and a temperature control module. The problem of sensor regeneration can be solved, the temperature control module controls the regeneration ceramic heater to heat a sensor sampling probe and burn deposited particulate matter by detecti
