The present application relates to the field of biological sample collection device, in particular to a biological sample collection information tracing device, comprising: a tube body for storing biological samples; a sealing tube cover detachably installed at the opening of the tube body; a trigger component arranged between the tube body and the sealing tube cover; a clock chip cooperating with the trigger component to determine the opening time of the sealing tube cover; a memory for storing the opening time detected by the trigger component; a near field communication module for transmitting the opening time stored in the memory to a reading device; a microcontroller for processing the state of the trigger component to determine whether the sealing tube cover is opened and transmitting the information of the opening time to the memory; a circuit board for connecting the trigger component, the clock chip, the memory, the near field communication module and the microcontroller. The present application realizes the digitization and objective tracing state of the biological sample as soon as it is collected from the outside.

The present application relates to navigation control technical field, especially to a kind of unmanned aerial vehicle navigation method and system based on vision and reinforcement learning, method includes: obtaining lagged first time visual image, real-time second time depth image and the continuous sensing data between them;Through the preset distillation vision network extraction global semantic features and with positive shadow image matching, the visual positioning anchor point of first time is solved;Inertial compensation positioning point of current time is obtained by using sensing data to calculate displacement and attitude change in time window, and mapping visual positioning anchor point to second time;Tensor splicing is carried out to inertial compensation positioning point and depth image to build reinforcement learning state space, and control instruction is generated by inputting strategy network;Through inertial compensation mechanism, the time-space deviation caused by visual calculation delay is eliminated, the flight trajectory oscillation problem caused by different step of multi-source heterogeneous data is solved, and the high robustness autonomous navigation and smooth control of unmanned aerial vehicle in dynamic environment are realized.

A SQL task link optimization method, device, equipment, storage medium and program product are disclosed, task related data of a SQL task is acquired, a dependency link between SQL tasks is filtered based on the task related data, wherein the dependency link is used to represent an association relationship between the SQL tasks, a directed graph network of the SQL tasks is constructed based on the filtered dependency link, the directed graph network is divided into at least two connected subgraphs, a SQL task in each connected subgraph is subjected to a merging feasibility test, a task merging decision is generated based on a test result, and a link of the SQL task is restructured and optimized according to the task merging decision. By adopting the embodiment of the present application, an execution exception of a SQL task can be captured in real time, system failure caused by problem accumulation can be avoided, and the management requirement of a high concurrency and large data volume SQL task link can be adapted.
