Disclosed are a transmitting device, a receiving device, a transceiver and an ultra wideband rock layer communication system, solving the problem that no reliable communication means is available when a serious accident occurs in a mine. The ultra wideband rock layer communication system of the present invention comprises two transceivers, and a pair of a receiving / transmitting electrodes and a receiving / transmitting switch corresponding to each of the transceivers, wherein a wireless channel is formed through the electrodes by using a rock layer as a transmission medium, thereby achieving a time division duplexing communication system. Each of the transceivers comprises a transmitting device and a receiving device. The transmitting device comprises a channel coding unit, an M-ary spread spectrum unit, a waveform forming unit, and a class-E power amplifier. An M-ary spread spectrum code has a chip value being a ternary pseudo random code of -1, 0 or 1. The class-E power amplifier is a push-pull power amplifier having an output transformer. The present invention has advantages of small signal duty ratio, high peak-to-average power ratio, good bit error performance, and long transmission distance, thereby providing a reliable communication means for mine disaster relief.

A drop testing machine and a method for adjusting a drop angle belong to the technical field of drop tests, aiming to solve the problems in the prior art that it is troublesome to adjust the posture of a test object, the angle control cannot be realized, and the drop test effect is poor. The drop testing machine of the present invention includes: a drop frame, which performs a rotary motion relative to its own rotating shaft; a lifting mechanism arranged on one side of the drop frame along the vertical direction; and a manipulator fixedly connected by a crank arm and the lifting mechanism. plate, an attitude adjustment unit connected between one end surface of the fixed plate and the crank arm, and two sets of grasping units symmetrically arranged on the other end surface of the fixed plate; the attitude adjustment unit drives the manipulator as a whole to realize horizontal and vertical rotations, The relative opening and closing movement of the two grasping units realizes the flexible grasping or releasing of the sample. The invention can realize the adjustment of arbitrary drop height and drop posture, realize the flexible grasping of the test object, and prevent the test object from being damaged or falling off due to the magnitude of the clamping force.
