Embodiment Construction

[0019] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 The structural block diagram of the present invention shown includes the main board and the sampling needle control board, the turntable control board, the suction pump control board, the printing control board, the keyboard control board and the signal conditioning and conversion board respectively connected thereto. The conditioning and conversion board is connected to the output terminal of the signal acquisition electrode on the sample box. The signal conditioning and conversion board receives the output signal of the signal acquisition electrode, and sends the signal to the main board after processing and conversion. The main board calculates the output signal according to the received signal. PO 2 value.

[0021] In this embodiment, since the functions of the four modules of printing control, injection needle...

Abstract

The invention discloses a process control system of a blood gas analyzer based on one master and multiple slaves. The process control system comprises a main board and a sample injecting needle control board, a turnplate control board, a suction pump control board, a printing control board, a keyboard control board and a signal conditioning and converting board which are connected with the main board, wherein the signal conditioning and converting board is connected with an output end of a signal acquiring electrode on a sample tank; the signal conditioning and converting board receives an output signal of the signal acquiring electrode, processes and converts the signals, and sends the signal to the main board; and the main board calculates a PO2 (oxygen partial pressure) value according to the received signal. According to specific subtasks in the system, microcontrollers with different performance are selected as the slaves to manage individual components, and a high-performance microcontroller is selected as a master to manage the multiple slaves so as to form the one-master and multi-slave system, thereby playing the performance of the microcontrollers, improving the performance and the flexibility of the blood gas analyzer and reducing the cost.

Description

technical field [0001] The invention belongs to the field of electronic measurement and control, and in particular relates to a master-multi-slave blood gas analyzer processing control system. Background technique [0002] The blood gas analyzer is a medical device used for blood testing. It can not only detect the content of oxygen, carbon dioxide and other gases in the patient's blood and the changes of blood pH and related indicators, but also quickly reflect the content of potassium, sodium and calcium in the blood. It provides a favorable guarantee for rapid and accurate detection in the rescue of critically ill patients. [0003] With the development of computer technology, computer technology has been widely used in the field of blood gas analysis, which makes modern blood gas analyzers have super data processing, maintenance, storage and expert diagnosis functions. direction of operation. [0004] At present, microcomputers such as PC104 are generally used to desig...
