Control system, method and medium for inhalation exposure system

Abstract

The invention provides a control system, method and medium for an inhalation exposure system. The control system comprises a user interaction module in charge of setting experiment parameters according to a user instruction and outputting an experiment instruction, one or multiple controller modules in charge of controlling operation of an experiment process according to the received experiment instruction and outputting a control instruction and one or multiple execution modules in charge of realizing measurement and control functions according to the received control instruction and outputting system parameters. The control system provided by the invention uses dedicated embedded system equipment as a main controller for realizing control on the whole process of an inhalation exposure experiment, and internal embedded software is developed on the basis of an RTOS. The dedicated controller and the embedded software have higher reliability compared with an upper computer, and control on the experiment process is executed by the main controller instead of the upper computer, so that stability of the control system is obviously improved from the whole system angle.

Description

Technical field [0001] The present invention relates to the field of toxicology experiments, in particular to a control system, method and medium of an inhalation exposure system. Background technique [0002] Inhalation exposure system is a kind of laboratory equipment used for inhalation administration or inhalation toxicology research. The respiratory system is the main way for oxygen to enter the human body, and drugs or toxic substances can also enter the human body through the respiratory system. The inhalation exposure system is to allow experimental animals to inhale drugs or toxic substances in a controlled manner under laboratory conditions to conduct research on the safety and effectiveness or toxicological effects of drugs. [0003] The inhalation exposure system usually consists of generators, monitoring and control parts, exposure chambers, and exhaust gas treatment. The test drug is in the form of dust, or in the form of a solution after being dissolved in a liquid...

AI Technical Summary

Problems solved by technology

[0011] 1. As the control core, the host computer runs a desktop operating system and various software components on top of it. It has complex functions and is not a dedicated exposed system controller. Therefore, compared with a dedicated controller, the stability of the experimental process control and less reliable

[0012] 2. The experimental process control is implemented on the host computer, and the management of multiple exposure systems will become very complicated and messy under the same user interface

In other words, under this architecture, the control of multiple experiments at the same time is more difficult to achieve

[0013] 3. The upper computer is directly connected to the sensor and actuator through the bus, so it is not easy to realize the remote operation interface
