Detection information transmission device and inspection device for hidden coverage goaf

The invention relates to the technical field of hidden coverage goaf detection, in particular to a detection information transmission device for a hidden coverage goaf and an inspection device. Comprising an underground communication terminal, a ground communication terminal and a data transmission unit connected with the underground communication terminal and the ground communication terminal. The underground communication terminal comprises a plurality of information transmission interfaces, a wide-frequency-band multi-channel data integration module and a first connector. And the ground communication terminal comprises a second joint and a wide-frequency-band multi-channel data decomposition module. The underground communication terminal integrates collected hidden coverage goaf information data into transmittable data through the information transmission interface and the wide-band multichannel data integration module, and then is connected with the ground communication terminal and the underground commun
