Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, the multi-rate adaptive test equipment based on the aviation FC bus mainly includes a clock detection module, a main control detection interaction module and a transmission control selection module. The clock detection module detects the symbol rate on the receiving physical cable and determines the FC The transmission rate of the transmission rate and the test results are passed to the main control detection interaction module. The transmission control selection module adapts to the data communication of the test end by adjusting the symbol transmission rate and related frame format settings. Aviation FC bus multi-rate self-adaptive test equipment also includes related peripheral equipment, which includes power supply module, crystal oscillator, memory, flash, display unit, etc.

[0032] Each module is descr...

Abstract

The present invention discloses a multi-rate adaptive test device based on an aviation FC bus. The device comprises a clock detection module, a main control detection interaction module and a sendingcontrol selection module. The clock detection module is configured to determine sending rate of a tested device according to received code elements sent by the tested device, and transmit the determined sending rate and the received code elements to the main control detection interaction module; the main control detection interaction module is configured to control a sending rate of the sending control selection module according to the received sending rate, package related test data into a related frame format and transmit the related frame format to the sending control selection module; andthe sending control selection module is configured to send the test data to the tested device according to the sending rate. The multi-rate adaptive test device based on an aviation FC bus can detectrelated code element rate of a related test bus port and complete a related test.

Description

technical field [0001] The invention belongs to avionics information integrated network bus technology, and is a multi-rate self-adaptive testing device based on FC bus. The device is compatible with 1G, 2G and 4G bandwidth transmission, and is applied in the development field of aviation data bus transmission protocol. Background technique [0002] Fiber Channel (FC) is a concept of comprehensive computer and network data communication. It is an open communication technology with high bandwidth, low delay, reliable transmission and high cost performance. It adopts channel control signal transmission technology and uses arbitration or switching means to process The problem of information sharing conflicts. In addition, technologies such as flow control are used. Compared with other network data bus protocols, the FC bus also adopts a layered protocol mode, which is divided into 5 layers, namely the physical layer, the transport layer, and the control layer. , service layer a...
