4results about How to "Improve polling efficiency" patented technology

The invention discloses an equipment broadcast message distribution method and system based on dynamic polling grouping, and belongs to the technical field of equipment broadcast, and the method specifically comprises the following steps: setting an initial query interval, sending a state query request to all equipment at every query interval by a central node, and sending a state message to all equipment after any equipment receives the query request; sending self monitoring data to a center instruction; obtaining a quantitative index in the monitoring data, generating a quantitative index sequence of any equipment every n query intervals, calculating an initial coefficient according to the quantitative index sequence, and converting the initial coefficient into an adjustment coefficient of the query intervals; calculating the duration of the next n query intervals according to the adjustment coefficient; a plurality of intervals are set, the devices with the adjustment coefficients in the same interval are divided into the same group, the query priorities of the devices in each group are ranked from large to small according to the numerical values of the adjustment coefficients, and polling is carried out in sequence according to the priorities.

This invention proposes an asynchronous invocation method and system for cryptographic cards. The method includes: device opening: the application opens the cryptographic card through the SDK main thread and creates a polling thread to query the returned data status; data sending: when the application calls the cryptographic service interface through the SDK main thread, the cryptographic service interface passes the calculation data, the sending process descriptor pid_send, the callback function parameters, and the callback function pointer to the driver and returns immediately without waiting for the cryptographic card's calculation result; data receiving: after the SDK polling thread queries the cryptographic service calculation result, it automatically executes the callback function to complete subsequent operations. This invention can effectively avoid the blocking of data interaction between the host application and the cryptographic card, improve the user experience, and fully utilize the performance of the cryptographic card.

The invention discloses a short-wave data chain message polling method based on state control and response. The short-wave data chain message polling method comprises the following steps: initializing a polling system, setting a polling entry switch comprising an opening state and a closing state, opening the polling entry switch, and starting a first timer; after the first timer is overtime, the first-class station initiates polling to the second-class station, a polling entry switch is turned off, and a second timer is started; when the polling system receives sending ending information of the first-class station before the second timer is overtime, the second timer is stopped, and the third timer is started; when the polling system receives a response message sent by the second-class station before the third timer is overtime, the third timer is stopped, and the fourth timer is started; when the polling system receives the stop code of the response data of the second-class station within the timeout time of the fourth timer, stopping the fourth timer, ending the polling, turning on the polling entry switch, and returning to the polling initiating step to prepare the next polling; according to the method, the polling efficiency of the data link message can be effectively improved under the condition of not increasing additional facilities.

The invention discloses a radar detection method, system and device and a storage medium, and the method comprises the steps: determining a plurality of radars participating in polling on a vehicle according to the current motion state of the vehicle; and grouping the plurality of radars to control the radars in each group to detect obstacles in parallel, so that the obstacle detection efficiency is improved.
