Abstract

In this paper, a safety of hazardous gas instruments for laboratory experiments was designed using a microcontroller and connected to personal computer to save the data. Here, the carbon monoxide gas (CO) and methane gas (CH4) sensors are applied to the systems to measure the concentration of gases in case of laboratory. Commonly, the gas instruments are used in object tested directly without considering the flow of gases toward the user. Comparing to that system, in order to protect the users’ safety from of direct contact with the gases, inlet-outlet pipes and fill-discharge tubes are used in this proposed system. The performance of the proposed system is analysed trough experiments. Some results were presented according to the time of activating inlet to inject the gas. Thus, the effect of changing the gas concentration was analysed.In this paper, a safety of hazardous gas instruments for laboratory experiments was designed using a microcontroller and connected to personal computer to save the data. Here, the carbon monoxide gas (CO) and methane gas (CH4) sensors are applied to the systems to measure the concentration of gases in case of laboratory. Commonly, the gas instruments are used in object tested directly without considering the flow of gases toward the user. Comparing to that system, in order to protect the users’ safety from of direct contact with the gases, inlet-outlet pipes and fill-discharge tubes are used in this proposed system. The performance of the proposed system is analysed trough experiments. Some results were presented according to the time of activating inlet to inject the gas. Thus, the effect of changing the gas concentration was analysed.

实验室实验用安全有害气体仪器的设计与分析

本文设计了一种用于实验室实验的危险气体安全检测仪器，并将其与个人计算机连接，实现数据的保存。在这里，一氧化碳气体(CO)和甲烷气体(CH4)传感器应用于系统，以测量实验室情况下的气体浓度。通常，气体仪器直接用于被测对象，而不考虑流向用户的气体。与该系统相比，为了保护用户与气体直接接触的安全，本系统采用了进、出口管和充、排放管。通过实验分析了该系统的性能。根据启动进气口的时间给出了一些结果。在此基础上，分析了气体浓度变化的影响。本文设计了一种用于实验室实验的危险气体安全检测仪器，并将其与个人计算机连接，实现数据的保存。在这里，一氧化碳气体(CO)和甲烷气体(CH4)传感器应用于系统，以测量实验室情况下的气体浓度。通常，气体仪器直接用于被测对象，而不考虑流向用户的气体。与该系统相比，为了保护用户与气体直接接触的安全，本系统采用了进、出口管和充、排放管。通过实验分析了该系统的性能。根据启动进气口的时间给出了一些结果。在此基础上，分析了气体浓度变化的影响。
