The invention discloses a switch cabinet condensate monitoring and processing method. The method concretely includes the following steps that a normal condensate threshold value in a switch cabinet and a normal inside and outside temperature difference threshold value of the switch cabinet are preset; condensate parameters in the switch cabinet are acquired according to a preset period; the acquired condensate parameters are collected so that an average condensate parameter can be obtained, then, the average condensate parameter is compared with the preset normal threshold value, details are described as follows, if the obtained average condensate parameter is lower than the normal condensate threshold value, the time interval of the condensate acquisition period in the switch cabinet is prolonged, if the obtained average condensate parameter is higher than the normal condensate threshold value, a dehumidification device is controlled to remove condensate till the condensate parameter is equal to the normal threshold value, and meanwhile the nest step starts; a temperature parameter in the switch cabinet and an outdoor temperature parameter are acquired in real time according to a preset frequency so that a temperature difference threshold value can be obtained, and comparison is performed according to the obtained temperature difference threshold value and the normal temperature difference threshold value. The method is simple, easy to achieve and capable of effectively controlling condensate of the switch cabinet.
