Embedded blood analyzer control system and control method thereof

Abstract

The invention discloses a control method of an embedded blood analyzer control system. The method includes that a main processor sends an instruction to a programmable logic device; the programmable logic device receives and analyses the instruction sent by the main processor and executes and sends a response message to the main processor; and the main processor receives, analyses and processes the response message sent by the programmable logic device. The disclosed control system comprises the main processor, the programmable logic device and a control unit group, the main processor, the programmable logic device and the control unit group are separated, and the main processor and the programmable logic device are connected through a serial bus. By means of the technical scheme, the main processor and the programmable logic device are separated through the serial bus, a fault-tolerant mechanism is added during data transmission, the problem that the main processor and the programmable logic device are mutual interfered due to the fact that the main processor and the programmable logic device are necessarily placed on the same circuit board is solved, and the problem that errors are prone to occur during data transmission due to a long connecting line when the serial bus is utilized is solved.

Description

technical field [0001] The invention relates to the technical field of medical diagnostic equipment, in particular to an embedded blood analyzer control system and a control method thereof. Background technique [0002] The mainstream processors of industrial control include single-chip microcomputer, DSP, ARM and CPU, etc. This type of processor is a fixed or customized device, usually called an application-specific chip (ASIC). In industrial control, multi-channel state monitoring and multi-channel command control are often required to be completed. Due to the limited number of external control interfaces and IOs of a single processor, it is difficult to directly complete the multi-channel monitoring task, so programmable logic devices are used as the extended processor interface to obtain widely used. Currently, the preferred device for programmable logic devices on the market is FPGA (Field Programmable Gate Array, Field Programmable Gate Array) or CPLD (Complex Program...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an embedded blood analyzer control system and its control method. The main processor and the programmable logic device are set separately and communicate through the serial bus, so as to solve the problem that the two must be placed in the same place due to the short communication line On the same circuit board, it is easy to interfere with each other. At the same time, by adding a fault-tolerant mechanism in the data transmission process of the two, it overcomes the error-prone problem in the data transmission process caused by the long connection line of the serial bus, and improves the system. Controller's Fault Tolerance
