Abstract

The invention relates to a cell analyzer capable of synchronously storing paths of pulse data and a control method of the cell analyzer. The cell analyzer comprises a light source generation module, light signal receiver modules, signal processing modules, ADC collection modules, an FPGA module and a DDR storage module. The number of the light signal receiver modules, the number of the signal processing modules and the number of the ADC collection modules are the same; and the light signal receiver modules, signal processing modules, ADC collection modules, FPGA module and DDR storage module are electrically connected in order. According to the provided cell analyzer, the FPGA module replaces a microcontroller, a parallel processing manner of the FPGA and abundant logic resources of the same are used, data synchronization units correspond to the paths of digital pulse data, the speed is improved by increasing the area, and thus, the paths of digital pulse data are synchronously stored.

Description

technical field [0001] The invention relates to a cell analyzer, in particular to a cell analyzer capable of synchronously storing multiple channels of pulse data and a control method thereof. Background technique [0002] In blood cell medical instruments, it is often necessary to analyze information such as cell volume and internal structure, which are key indicators that affect the performance of the hemocytometer. At present, the cell measurement method commonly used in hemocytometers-laser scattering method, when the laser irradiates the cell particles, multiple optical signal receivers are placed at different angles in the range of 0-90° of the cell, and multiple optical signals need to be stored synchronously. Upload to the algorithm to ensure that no data is lost, so that the characteristics required by the cells can be analyzed normally on the algorithm platform. [0003] The existing multi-channel data storage method is mainly based on the serial storage method of...
