Embodiment Construction

[0033] In the MARS system, there is no clear mechanism for how to relay discrete IO signals.

[0034] In order to solve the above problems, an embodiment of the present invention provides a signal transmission method. The signal transmission method provided by the embodiment of the present invention only needs to collect and replay the electrical signal waveform, and cooperate with the photoelectric adapter to realize the relay of the discrete IO signal. Discrete IO signals are transparently transmitted, and the signal timing at the source end is completely reproduced at the opposite end of the communication. It can be transmitted in multiple channels at the same time, improving the integration of the laboratory system.

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments c...

Abstract

The invention provides a signal transmission method, and relates to the field of communication. The signal transmission method solves the problem of absence of a relay processing mechanism for discrete IO (input output) signals. The method includes the steps: collecting the discrete IO signals by a relay card; processing the discrete IO signals by the relay card to obtain data in a photoelectric adapter bus interface format; and transmitting the data to a photoelectric adapter through a bus interface of the photoelectric adapter by the relay card. The signal transmission method is applicable to an MARS (memory-address register storage), and the discrete IO signals are processed by the MARS.

Description

technical field [0001] The present invention relates to the communication field, in particular to a signal transmission method. Background technique [0002] The multi-purpose avionics relay system (MARS) is used to realize the avionics relay network for remote interconnection between discrete laboratories. It is connected to various electrical interfaces through a variety of electrical adapter cards. The various electrical adapter cards will be different The electrical signal is converted into the data format required by MARS, and one optical adapter converts the data into optical signal for transmission; the other optical adapter converts the received optical signal into the data format required by the electrical adapter card, and the electrical adapter card receives The data outputs various electrical signals and completes the relay of electrical signals. [0003] In the MARS system, there is no clear mechanism for how to relay discrete IO signals. Contents of the inve...
