Data acquisition module and data acquisition system

Abstract

The invention discloses a data acquisition module and a data acquisition system. The data acquisition module comprises a microprocessor unit used for realizing interface control according to usage requirement and a field programmable gate array (FPGA) unit which is connected with the microprocessor unit by virtue of a bus and is used for providing interface receiving data and uploading to the microprocessor by virtue of the bus interface after compression and screening are carried out on data. The embodiment of the invention adopts a framework that a microprocessor Power PC unit and an FPGA unit coordinate in use, the Power PC unit is embedded with multiple interface controllers and has the characteristic of simplicity in debugging, and debugging time can be saved. The FPGA unit is provided with multiple high-speed data interfaces, speciality is strong, plug-in of multiple interfaces can be easily realized, and the connection operation is simple and flexible. The data acquisition module and the data acquisition system which are disclosed by the embodiment of the invention can adapt relatively serve ambient temperature, and stable operation of the system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition module and a data acquisition system. Background technique [0002] The data acquisition module is a communication module based on the remote data acquisition and control platform. The remote data acquisition module is mainly used in the fields of multi-interface, large data volume, and complex network connection transmission, including flight control, remote data acquisition and control, etc., especially in the interface Fields with high bandwidth requirements, poor ambient temperature, and a large number of external devices have obvious advantages. [0003] The current data acquisition module has a relatively single function. There are acquisition cards that only use the PCIE (bus interface) interface, and there are acquisition cards that only use the 1553B interface. The single board card is not very versatile. In the face of a communication platfo...

Problems solved by technology

[0003] The current data acquisition module has relatively simple functions, there are acquisition cards with only PCIE (bus interface) interface, and there are acquisition cards with only 1553B interface, and the single card is not very versatile.

In the face of a communication platform with a relatively complex network, it is necessary to select a data acquisition card with various interfaces and rates to meet the system requirements. For a system with a long transmission distance, an additional relay device needs to be selected, which has a complex structure and poor stability.
