地下水、水库等水位的变化情况直接和人类生活息息相关。目前一般采用水尺或水位计进行水位测定,很多时候只能在现场进行人工水位测量,往往造成观测结果不准确等问题。为解决人工操作带来的不利影响,通过采用嵌入式系统搭建B/S架构的远程水位监测系统,能实现24 h水位实时监测和数据存储,可远程进行数据下载和查看,系统测量分辨率可达1 mm,测量精度在2 cm以内,既可用于单点的监测,也可用于多点区域性分布式监测。经试验证明,该水位监测系统能实现长期稳定的水位观测,能满足大部分水位监测领域的需求。

The fluctuation of groundwater level and reservoir water level is closely related to human’s social life. Currently adopted water level gauge usually results in inaccurate measurements. In order to reduce the adverse impacts caused by manual operation, we built an embedded remote water level monitoring system using B/S architecture to accomplish 24 hours real-time monitoring, data storage, and remote data download and inquiry with the measurement resolution reaching 1 mm and the measurement accuracy within 2 cm. The system can be used for single point monitoring, and also distributed multi-point regional monitoring. Experiments have proved that the present water level monitoring system could accomplish long-term stable water level observation, and could meet the demands of most water level monitoring fields.
