The present invention discloses a UAV communication system, including a UAV end, a ground end, a communication link sending module and a communication link receiving module. The communication link sending module is used to carry TB on channel time-frequency resources and send it to the communication link receiving module according to a preset resource allocation scheme; the communication link receiving module is used to distinguish different TBs and different copies of TBs, and screen according to two TB indication fields in the correctly received TBs to obtain valid data contained in the TBs. The present invention carries the transmission blocks to be repeatedly sent on the redundant channel resources of the UAV communication link, and sends copies of the same TB on channel resources with different frequencies and / or different times to obtain the effect of additional frequency diversity gain and / or time diversity gain, compensating for the adverse effects of the frequency selective fading and / or time selective fading characteristics of the wireless channel on the correct reception of the signal, so as to achieve the purpose of making full use of the available channel resources to improve the quality and reliability of link data transmission.

The invention discloses a drop hammer impact test lifting device and a drop hammer impact tester, and relates to the technical field of drop hammer test device structures, the drop hammer impact test lifting device comprises a support, a bearing frame, a driving device, a hanging structure, an unlocking structure and a protection structure, the bearing frame is installed on the support; the driving device is used for driving the bearing frame to move up and down on the bracket; the hanging structure comprises two hooks rotationally mounted on the bearing frame, hook parts of the two hooks are located below the rotating axis of the hooks and are oppositely arranged, the two hooks are provided with unlocking positions and hanging positions, and the two hook parts are used for being hung on the hanging parts of the drop hammer when the two hook parts are located at the hanging positions; the unlocking structure is mounted on the bearing frame and is used for driving the two hook parts to move from the hanging position to the unlocking position so as to release the drop hammer; the protection device is installed on the bearing frame and comprises a protection pin which can be horizontally and movably installed on the bearing frame. The invention aims to provide the drop hammer test device which is high in safety and convenient to control.

The application discloses a hibernation method of a low-power-consumption image acquisition device, an electronic device and a storage medium. The hibernation method of the low-power-consumption image acquisition device is applied to the image acquisition device, and comprises the following steps: acquiring an initial storage time consumption of the image acquisition device for storing initial storage data; adjusting a preset waiting hibernation time length according to a comparison result between the initial storage time consumption and the preset waiting hibernation time length, to obtain a target waiting hibernation time length; and in response to the current working time length of the image acquisition device being equal to the target waiting hibernation time length, controlling the image acquisition device to enter a hibernation mode. According to the above scheme, the time when the low-power-consumption image acquisition device enters the hibernation mode can be flexibly adjusted, so that the data storage efficiency of the low-power-consumption image acquisition device is improved.

The present invention discloses a glue curing monitoring method based on optical path difference change, which belongs to the field of glue curing monitoring, including: configuring a test scheme, establishing a test environment, and configuring environmental characteristics; placing a test sample in the configured test environment, and performing sample timing monitoring, and establishing a curing timing data set; establishing and updating phase data, and establishing timing curing data of the cured glue; establishing a predictive fitting model, and performing a fitting test, and establishing a fitting test result; judging whether the fitting test result meets a preset test threshold, and when it meets, completing the glue curing monitoring of the cured glue through the predictive fitting model. The present application solves the technical problem that the contact monitoring used in the existing glue curing monitoring requires puncturing the colloid, resulting in damage to the colloid, and achieves the technical effect of establishing a predictive fitting model through non-contact multi-point monitoring of the spectrometer and phase data analysis, thereby performing glue curing monitoring and realizing non-destructive monitoring of the glue curing process.
