The invention provides a telescopic diving transportation boat and a detection device and method thereof. The transportation boat comprises a front section (a driving cabin and a front cabin), a middle section (an annular piston and an annular hydraulic cylinder) and a rear section (a rear cabin and a motor steering engine cabin), the three sections are connected into a whole through flanges and bolts, when the annular piston moves back and forth in the cylinder, the volume and the specific gravity of the boat are changed, and the purpose of submerging and surfacing is achieved. The piston ring ensures sealing in the cylinder, and the stability of the boat sailing on the water surface and underwater is provided through cooperation of the stabilizing rod and the stabilizing sleeve. The boat is constructed in the land workshop in a segmented mode, detection is conducted in the land workshop in a segmented mode by simulating various conditions during submerging, time and labor are saved, and safety is achieved. The boat has the main advantages that the structure and operation are simple, the cabin capacity is large, the speed of personnel and goods entering and exiting the cabin is high, and batch production can be achieved. The device is mainly used for seabed sightseeing, undertaking transportation tasks when sea conditions are severe, and carrying out landing combat when necessary.

The invention discloses a printing method and device of chip software and hardware simulation character strings, equipment and a medium, and relates to the technical field of chip embedded simulation, and the printing method of the chip software and hardware simulation character strings comprises the following steps that S10, a preset printing function is executed in response to a printing instruction, obtaining a character string needing to be printed according to the obtained character string address; wherein the preset printing function is edited based on a character string address; and step S20, printing the obtained character string. According to the method, the original printing function based on one-by-one printing of the single characters is modified into the printing function based on the character string address, and when the instruction of printing the character string is executed, the time required for printing can be shortened, so that the simulation time can be saved, and the simulation efficiency can be improved. In addition, too many resources of the chip CPU are not occupied when the serial port is written.

This invention discloses a collaborative interference avoidance method and system for millimeter-wave SAR radar in high-density multi-platform scenarios. The method first acquires parameters of each millimeter-wave SAR radar within a region via a bypass communication link; then, it predicts the overlap probability and equivalent interference energy of inter-radar interference signals entering the receiver's baseband low-pass passband, constructing a regional radar conflict map; under imaging performance constraints, it jointly optimizes the center frequency, operating bandwidth, frequency modulation slope, sweep duration, transmit start time slot, sampling rate, and low-pass cutoff frequency of each millimeter-wave SAR radar; finally, the optimized parameters are sent to the corresponding radars for execution, thereby reducing the total regional interference energy, decreasing the FMCW radar interference probability, enhancing the anti-interference performance SINR index, and improving the coexistence imaging capability of millimeter-wave SAR radar in high-density environments. This invention is applicable to scenarios such as autonomous driving, low-altitude air traffic, drone logistics, urban emergency rescue, and urban three-dimensional monitoring.

This application discloses a database-based method, apparatus, and system for web service log analysis and error tracing, comprising: acquiring runtime exception logs containing thread ID, timestamp, and call stack, and interface access logs containing interface name, thread ID, interface entry timestamp, and response time; accurately matching the two types of log records based on the condition that the thread IDs are the same and the runtime exception timestamp is within the window formed by the interface entry timestamp and the interface entry timestamp plus the response time; associating the matched interface with the responsible developer based on a pre-defined interface-developer mapping relationship; and finally pushing the error details and developer information to the corresponding terminal. This application utilizes the thread ID + time window matching mechanism and responsibility mapping to automate the entire process from error discovery and responsibility determination to dispatch, solving the problems of difficult error location, unclear responsibility attribution, and low dispatch efficiency in large-scale development teams, and significantly shortening the problem resolution cycle.
