Embodiment 1

[0018] Such as figure 1 As shown, the high-speed data acquisition module includes an FPGA, and the FPGA is connected with an ADC data acquisition module and a clock distribution module, and the ADC data acquisition module is connected with the clock distribution module, and the FPGA is also connected with an EPROM, a CPCI bus and a CPCIe bus. FPGA3 is loaded with fixed EPROM,

[0019] The high-speed ADC performs analog-to-digital conversion in a 4-way interleaved manner, so each way generates an 8-bit data at a frequency of 750MHz. The data traffic of each channel is 750MHz×8bit. Due to the limitations of FPGA resources, I / O pin frequency and pin size, each channel of data is first divided by a piece of FPGA to generate 16 channels of 187.5MHz 8-bit data. This increases the speed of data transfer.

[0020] One of the indicators that affect the dynamic performance of the ADC is the clock module. The clock module must have very small clock jitter and phase noise. The more se...

Abstract

The invention discloses a high speed data collecting module which comprises an FPGA. The FPGA is connected with an ADC data collecting module and a clock distribution module. The ADC data collecting module is connected with the clock distribution module. The FPGA is further connected with an EPROM, a CPCI bus and a CPCIe bus. The ADC data collecting module is used for sampling data and transmitting the data to the FPGA to be further recognized and sorted, and then the data are transmitted to the CPCI bus and the CPCIe bus through the FPGA. The signal processing capability can be improved, data uploading time is shortened, and the high speed data collecting module is fast and convenient to use.

Description

technical field [0001] The invention relates to a data acquisition module, in particular to a high-speed data acquisition module. Background technique [0002] The data acquisition module is based on the communication module of the remote data acquisition module platform. The remote data acquisition module is mainly used in the field of mobile data transmission, including vehicle navigation monitoring, smart meter reading, remote data acquisition and other fields, especially in multimedia transmission with relatively high bandwidth requirements In the field, the remote data acquisition module has obvious bandwidth advantages. [0003] The current data acquisition module only uses the CPCI bus to have limited advantages in data transmission and takes a long time to upload data, which brings many problems to future development. Contents of the invention [0004] In order to solve the above problems, the present invention provides a high-speed data acquisition module capable...
