The application discloses a kind of intelligent landslide body burying condition under life search and rescue device and method, including shell, detection component being set in the inside of shell, for detecting life, the detection component is by hand-held tablet and detection host wireless connection composition, need not data line connection, can conveniently data transmission, battery compartment is opened on the detection host, separate battery that is inserted into battery compartment is placed in the inside of shell, battery cover is further provided on the top of battery compartment, the both ends of battery cover are provided with the connecting component connected with detection host;Through the connecting component of design, replace the installation of the mode of present by hand screw bolt, simultaneously, the dismounting of battery cover is very convenient, work efficiency is improved, simultaneously, the connection loss of this connecting component is less, and the use fatigue of structure such as existing bolt, spring does not appear, overall service life is longer, and manufacturing cost is lower.

The application provides a modular radio frequency receiving front end with fast power-on capability. The modular radio frequency receiving front end comprises a filtering limiting front end, a switch filtering amplification circuit, a power division circuit, a large dynamic SDLVA circuit and an SDLVA power supply circuit, and is connected with each functional module through an SMP joint to realize modular design, detects the performance of each circuit through multi-stage self-checking, increases the isolation degree between the SDLVA chip and the rear-stage operational amplifier circuit through an operational amplifier, and provides the power supply voltage of the ns level rising edge for the SDLVA detection module, so as to reduce the complexity of the radio frequency signal interconnection and the power supply control wiring of the multi-channel receiving front end, and has the characteristics of modular design, high sensitivity, high reliability, strong universality and the like.
