瓦斯巡更监测分站的设计

Design of gas watchman tour monitoring and measurement substation

为了有效监管瓦检员到达巡检地点检测瓦斯浓度,介绍了一种能够保证瓦检员到达巡检地点检测数据并同时把数据传给上位机软件的瓦斯巡更监测分站。详细阐述了各关键部件的组成和软件的工作流程。该系统以单片机AT89C2051为核心,以红外方式与便携式瓦斯检测仪进行数据传输,以RS-485通信方式与上位机进行数据传输。现场使用证明,该监测分站工作稳定可靠。

In order to effectively monitor and manage the gas inspector to inspect the gas content at the his inspection places, the paper in- troduced a gas watchman tour monitoring and measuring substation, which could ensure the gas watchman to inspect and measure the data at the his inspection places and meanwhile to send the data to the host computer's software. The paper in detail stated the composition of each key parts and the work process of the software. The system is based on AT89C2051 single chip microcomputer as the key. The data transmission would be conducted with the infrared communication between the system and the portable gas detector. The data transmission between the system and host computer would be conducted with the RS -485 communication mode. The site application showed the per- formances of the substation was stable and reliable.
