CAN bus structure for full automatic medical detecting instrument

Abstract

The invention discloses a CAN bus structure for a full automatic medical detecting instrument. The CAN bus structure comprises a CAN bus system connected with master control, wherein CAN transceiversand CAN controllers are connected with a CAN bus; the CAN controllers are connected with sub-module controllers; the sub-module controllers are connected with sub-module performance mechanisms and multidigit dip switches. According to the CAN bus structure, the master controller of the medical detecting instruction and auxiliary sample injection module, detection module, signal conversion module,display and print module and data storage module at the periphery of the instrument are mounted on the CAN bus and the modules are relatively independent, so the development efficiency can be improved, the universality is relatively high, and certain module can be added or deleted relatively conveniently. A control algorithm is relatively mature, the intelligent level of the medical detecting instrument can be improved, and certain fault self-checking capability is achieved. The controllers are connected with the sub-modules in a CAN bus mode, so the stability and the anti-interference performance of the system are improved.

Description

technical field [0001] The invention relates to an intelligent medical detection instrumentation system, in particular to a CAN bus of a fully automatic medical detection instrument. Background technique [0002] In recent years, with the improvement of people's living standards and the aging of my country's population, the demand for high-quality medical care and medical testing products is also increasing. In recent years, my country has also developed rapidly in the field of medical testing, but in general, compared with developed countries, there is a big gap in the research and development of medical testing instruments in my country in terms of intelligence and reliability. Modern fully automatic medical testing instruments With the improvement of the degree of intelligence, the internal circuits and systems of the instruments are becoming more and more complex. The internal system of traditional medical testing instruments is often a whole, which not only greatly reduc...

In recent years, my country has also developed rapidly in the field of medical testing, but in general, compared with developed countries, there is a big gap in the research and development of medical testing instruments in my country in terms of intelligence and reliability. Modern fully automatic medical testing instruments With the improvement of the degree of intelligence, the internal circuits and systems of the instruments are becoming more and more complex. The internal system of traditional medical testing instruments is often a whole, which not only greatly reduces the reliability and maintainability of the entire system, but also the versatility and modularity. The degree of automation is low, which not only reduces the development efficiency, but also makes it difficult to modify and upgrade the detection instruments in the future.
