The invention discloses a fiber grating temperature monitoring device for a switch cabinet. The fiber grating temperature monitoring device comprises a processor and a remote monitoring terminal, wherein two signal input ends of the processor are electrically connected with the output ends of a clock module and an A/D converter respectively; three signal input ends of the A/D converter are electrically connected with the output ends of a grating sensor, an electromagnetic sensor and a photosensitive sensor respectively; a first output end of the processor is connected with the input end of a data storage module. The invention further provides the fiber grating temperature monitoring device of the switch cabinet. Temperature monitoring is carried out on the switch cabinet through cooperation of the fiber grating sensor and the electromagnetic sensor; by the photosensitive sensor and an optical focus lens arranged on the surfaces of the photosensitive sensor, the function of monitoring the internal condition and the temperature of the switch cabinet is added; when the temperature rises and an accidental condition is generated, a worker can know the location of the problem in the first time; good conditions are provided for remediation after the problem appears.
