The application discloses a novel industrial multifunctional pulse eddy current probe and relates to the technical field of pulse eddy current detection.The probe shell is internally provided with excitation assemblies and a Hall sensor.The excitation assemblies are in multiple groups, the Hall sensor is arranged at the center of the excitation assemblies, and the excitation assemblies are arranged in a circumferential array around the Hall sensor.The application is not easily disturbed by other magnetic fields or electric fields in the surrounding environment, can reduce signal fluctuation and errors caused by external interference to a certain extent, and improves the reliability and stability of probe detection.

The application provides a multi-frequency antenna remote controller, which comprises a shell, a cavity in the shell, an external antenna assembly arranged on the top of the shell, an internal antenna assembly arranged on the top of the cavity, and a picture transmission PCB arranged in the cavity and connected with the external antenna assembly and the internal antenna assembly through feed lines, wherein the external antenna assembly and the internal antenna assembly have different transmitting frequency bands. The external antenna shared by 1.4G / 2.4G frequency bands and the internal antenna of the 5G frequency band are arranged, so that when the signal of a certain frequency band is lost, communication can be switched to another frequency band, and the remote controller is not easily interfered. In addition, the structure of the external antenna and the internal antenna is simple, so that the structural cost is reduced, and the remote controller is more beautiful.
