文章以哈尔滨理工大学为例,从软件工程专业人才培养现状及问题出发,构建了基于"卓越计划"的工程应用型人才培养模式,并分析了人才培养成效。

For the issues existing in the traditional environmental information acquisition system, such as high costs, inflexibility of acquisition equipment layout and so on, proposed a low-cost scheme of campus environmental information acquisition system according to the functional requirements. Envi-ronmental information, such as temperature, humidity, noise, air contaminants and so on, was collected in real time by sensor nodes that were deployed on campus. By the Zigbee wireless sensor network technol-ogy, the data was pooled to the server through the gateway, and then was processed into a graphical user interface that could monitor real-time campus environmental quality. The design of system is described in detail, includes acquisition node and the server. The experiment shows that the system is reasonable and feasible, it can realize timely collection, and works stable during data processing.
