Problems solved by technology
[0003]
For the selection of signal transmission channels, the existing technology mainly adopts one channel for processing, and there is a problem: once the equipment fails, signal transmission cannot be performed, and there is no alternative for one set of equipment. If the failure cannot be solved in time, another new set can only be selected. equipment, the signal is subject to many interference factors in reality, and the risk of relying on one channel alone is very high
If multiple channels are directly selected, the more channels there are, the more alternatives will be. One channel needs to use a complete set of acquisition and processing equipment, but the cost is difficult to control, and the processing difficulty is also very huge. The applicability lies in both cost and technical difficulty. met with great resistance

Embodiment Construction
[0032] All features disclosed in all embodiments in this specification (including any appended claims, abstract and drawings), or steps in all methods or processes implicitly disclosed, except for mutually exclusive features and / or steps, can be used as Combining and / or extending, replacing in any way.
[0033] Such as Figure 1-11 Shown, a kind of channel selection method based on FPGA signal processing, comprises steps:
[0034] S1, store the signal frequency in the memory, and establish the mapping relationship between the signal frequency and the channel, obtain the corresponding signal frequency by accessing the storage address of the signal frequency in the memory, and complete the mapping between the channel and the signal frequency;
[0035] S2, judging whether the channel and signal frequency mapping is completed, if completed, enter step S3, otherwise jump back to step S1;
[0036] S3, determine the parameter configuration of multiple channels in turn, if it is a s...

The invention discloses a channel selection method based on FPGA signal processing. The method comprises steps of S1, storing a signal frequency in a storage, building a mapping relation between the signal frequency and a channel, obtaining a corresponding signal frequency through the access to a storage address of the signal frequency in the storage, and completing the mapping between the channeland the signal frequency; S2, judging whether the channel and signal frequency mapping is completed or not, if so, entering the step S3, and otherwise, jumping back to the step S1 and the like; the FPGA development platform gives consideration to cost and feasibility of signal transmission, avoids defects of a single channel in an existing scheme, effectively guarantees transmission of the information, carries out processing and judgment of the signal quality, selects a channel with high-quality signals for signal transmission, is very efficient for signal processing and data interaction, andimproves development efficiency; engineering usability is higher.
Description
technical field [0001] The present invention relates to the technical field of data transmission, and more specifically, relates to an FPGA-based signal processing channel selection method. Background technique [0002] Facing the world's fierce technological competition environment, it is very important to be able to transmit information effectively and at high speed. The transmission of information is the transmission of signals. [0003] For the selection of signal transmission channels, the existing technology mainly adopts one channel for processing, and there is a problem: once the equipment fails, signal transmission cannot be performed, and there is no alternative for one set of equipment. If the failure cannot be solved in time, another new set can only be selected. The equipment, the signal is subject to many interference factors in reality, and the risk of relying on one channel alone is very high. If multiple channels are directly selected, the more channels the...
