Abstract

The invention discloses a multi-channel parallel synchronous bus controller, which includes MCU and FPGA, and the FPGA includes: a plurality of bus controllers connected to corresponding bus device circuits through corresponding types of buses; a plurality of configuration registers are used to Carry out bus configuration to each bus controller according to the instruction of described MCU; Clock, be used to control data acquisition clock; Data storage module, be used to store the sampling data that each bus controller returns at the same time for MCU to read; Sampling control The device is used to receive instructions from the MCU to perform sampling settings, and according to the sampling settings, when the sampling clock arrives, adjust the sampling start signal sending time of each bus controller so that the sampling data return time of each channel is consistent. The invention has multi-channel concurrency, fast data reading speed, does not occupy the MCU bus interface, and is suitable for the application requirements of multi-channel, large data volume, high speed, and synchronous data acquisition of parallel bus devices.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a multi-channel parallel synchronous bus controller. Background technique [0002] During the design process of rocket engines and aero-engines, a series of combustion characteristics tests are required for the engines. In order to obtain accurate characteristic parameters, it is necessary to measure the pressure parameters of different sections and orientations of the engine inlet, combustion chamber, nozzle, etc. , Pressure measurement channels can reach hundreds. [0003] At present, many pressure sensors are digital sensors, and most of them are bus interfaces, so that a measurement controller can collect multiple signals. However, because the bus communication must adopt a time-sharing method, when the number of sensors is large, the average data sampling rate will drop. Moreover, the acquisition of each channel needs to be carried out serially, not strictly synch...
