The invention relates to an automatic marine data downloading method and system, and belongs to the technical field of data transmission, and the method comprises the steps that downloading parameters and task parallel requirements are acquired, and the downloading parameters comprise remote server information and the number of downloaded files; a downloading thread is created through a main thread according to the number of downloaded files and task parallel requirements, and the downloading thread independently sends a downloading request to a remote server; the remote server sends a downloading file to a downloading thread according to the downloading request, the downloading thread processes data of the downloading file in parallel according to a preset semaphore, the downloading file is stored in a database, and a downloading success notification is sent to the main thread; transmitting the successfully downloaded download file to a remote server through an asynchronous mechanism; wherein the asynchronous transmission step and the multi-thread downloading step are carried out in parallel; through multi-thread parallel downloading and asynchronous transmission, quick and reliable downloading and distribution of files are achieved, the number of downloading threads is controlled through semaphores, and stability and high efficiency of the downloading process are ensured.

The invention relates to a method for estimating a ratio of NOx and NH3 concentrations downstream of at least one SCR catalytic converter (22) of an internal combustion engine (10) arranged in an exhaust gas system (11).

An electric power converter is electrically connected to an electric storage device. The electric power converter includes a control unit that, according to the voltage measured by the electric power converter, refers to, as the output target for the electric storage device, a reference function which has a drooping characteristic and which represents a control target function. The reference function has a constant-input-output region over a predetermined voltage range, and is updated based on the battery status of the electric storage device.

This invention provides a shielded cable installation mechanism, relating to the field of cable installation technology, including cables; it also includes a locking mechanism, which has two sets, including a fixed cylinder, the cable being slidably connected to the fixed cylinder, one end of the fixed cylinder having multiple sets of locking grooves, and the other end having a rotating groove, the rotating groove having multiple sets of balance springs, the fixed cylinder having multiple sets of sliding grooves, the outer wall of the fixed cylinder having a hexagonal groove, the rotating groove having a locking ring rotatably connected to it, the locking ring having multiple sets of unlocking grooves, the multiple sets of balance springs corresponding one-to-one with the multiple sets of unlocking grooves, the two ends of the balance springs being fixedly connected to the inner side wall of the unlocking groove, and the outer wall of the locking ring having multiple sets of friction strips. This invention overcomes the problem of traditional cable installation requiring separate fixing of the cable body, shielding tube, and corrugated tube, and designs an integrated synchronous locking mechanism, realizing one-time rapid synchronous locking of the cable, shielding tube, and corrugated tube.

The embodiment of the invention provides a subtitle display method, a subtitle system, computing equipment and a readable storage medium, the subtitle display method is applied to a server side of the subtitle system, and the subtitle system further comprises at least one display terminal. The method comprises the following steps: acquiring voice data collected from a target scene; performing voice text transcription on the voice data to obtain text data; packaging the text data to obtain network packet data; and distributing the network packet data to at least one display terminal through a data transmission interface corresponding to the at least one display terminal, so that each display terminal generates and displays subtitle data of the target scene based on text data in the network packet data. The calculation burden of the display terminal is relieved, the subtitle generation and display delay is remarkably reduced, the user experience is improved, the overall performance and expansibility of the system are improved, and the subtitle display reliability and stability are improved.
