Embodiment Construction

[0046] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

[0047] The bus communication cycle refers to the interval between two adjacent frames of data packets transmitted in the bus. For applications requiring real-time communication in the industrial field, the bus communication cycle directly determines the response time of the system. For example, for the standard bus communication protocol applied in the physical layer of RS485 or RS422, there are clear requirements for the time interval of two adjacent frames of messages on the bus. For ...

Abstract

The invention discloses a bus communication cycle test system and method. The system comprises a communication protocol used for communication between an upper computer device and a lower computer device; the lower computer device is used for testing a bus communication period when receiving the start monitoring request and sending a test result to the upper computer device in a data packet form; and the upper computer device is used for sending a monitoring starting request, receiving the test result sent by the lower computer device and determining a bus communication period according to the test result. Therefore, the test system for the bus communication cycle is more flexible to install, the bus communication cycle can be automatically tested, and meanwhile, the communication reliability is improved.

Description

technical field [0001] The present application relates to the field of nuclear power technology, and in particular, to a system, method and computer-readable storage medium for testing a bus communication cycle. Background technique [0002] In the related art, indirect and manual testing methods are used to test the bus communication cycle, for example, the oscilloscope captures the bus waveform for manual judgment, or the test code is inserted into the firmware of the bus communication device. However, the above-mentioned test method will lead to low test efficiency, inaccurate measurement, and cumbersome test environment setup. Therefore, how to better realize the test of the bus communication cycle has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0003] The purpose of this application is to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to propo...
