The utility model discloses a temperature field non-contact detection system based on electromagnetic ultrasound. The system includes a microcontroller, a transmission circuit, an electromagnetic ultrasonic probe, a receiving switch, an acoustic signal acquisition module, an echo data processing module and a display module. An output end of the microcontroller is connected with an input end of the transmission circuit. An output end of the transmission circuit is connected with an input end of the electromagnetic ultrasonic probe. An output end of the electromagnetic ultrasonic probe is connected with an input end of the receiving switch. An output end of the receiving switch is connected with an input end of the microcontroller. Another output end of the receiving switch is connected with an input end of the acoustic signal acquisition module. An output end of the acoustic signal acquisition module is connected with an input end of the echo data processing module. An output end of the echo data processing module is connected with an input end of the display module. The system is capable of achieving an objective of rapidly and accurately obtaining the surface temperature and internal non-uniform temperature field of an object.
