The invention discloses a method for shortening instrument acquisition data link delay and a corresponding instrument, and the method comprises the following steps: a subunit acquiring data by takinga current measurement period as a period, and inserting the acquired data into the tail of an intelligent queue; the main unit reading the acquired data from the head of the intelligent queue by taking the measurement period as a period; wherein the queue length of the intelligent queue is adaptively adjusted according to the measurement period, so that when the measurement period becomes longer,the delay of the acquired data on a data link is shortened by shortening the queue length. The length of the intelligent queue is variable, the intelligent queue can adapt to different measurement scenes, and the data delay is optimal on the premise that data is not lost.
Description
technical field [0001] The present application relates to the field of instruments, in particular to a method for shortening the data link delay of instrument collection and corresponding instruments. Background technique [0002] At present, when the instrument industry collects data through the bus, it mainly uses a fixed queue to solve the problem of data loss caused by the inability to achieve absolute consistency between data collection and data reading cycles. However, fixed queues can cause substantial delays for data on the link. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for shortening the delay of the instrument collection data link, which includes the following steps: the subunit collects data with the current measurement cycle as the cycle, and inserts the collected data into the tail of the intelligent queue The main unit takes the measurement period as a period to read the collected data f...
