- 摘要:
- 供水系统监测网是获取爆管数据进行有效爆管监控的前提。流量大的管段往往为配水干管，其发生爆管危害性更大；管段流量相同的情况下，长度越长意味着爆管发生的可能性越大，沿线用户更多，则爆管发生后的排查难度也更大。因此，通过引入管段流量及管段长度两个重要性参数，对新增压力监测点的布设位置及数量进行优化，提升重要管段的爆管监测覆盖率。采用启发式算法求解优化问题，并在中国南方某大型城市管网的一个区域进行方法验证。与未考虑管段重要性参数的结果进行对比，考虑重要性参数后，当新增5个监测点时，DN400~600管段的增加监测率由41.9%提高至54.8%，DN700~1 800管段则由28.6%提高至78.6%；当新增25个监测点时，DN700~1 800管段的增加监测率由78.6%提高至100%，重要管段优先得到监控。
- Abstract:
- The monitoring network of water supply system is the prerequisite to obtain pipe burst data for effective pipe burst monitoring. The pipe sections with large flow rate are often the distribution mains, and the burst of these pipes is more harmful. In the case of the same flow rate in these pipe sections, a longer length means a greater possibility of pipe burst, more water consumers along the line, and more difficulty in burst location. Therefore, this paper introduced two important parameters including pipe section flow and pipe length to optimize the location and number of new pressure monitoring points, so as to improve the burst monitoring coverage of important pipe sections. The optimization problem was solved by using heuristic algorithm, and the method was verified in a district of a large city pipe network in southern China. Compared with the results without considering the importance parameters of pipe sections, when 5 pressure monitoring points were added after considering the importance parameters, the increased monitoring rate raised from 41.9% to 54.8% for DN400-600 pipe sections and from 28.6% to 78.6% for DN700-1 800 pipe sections. When 25 pressure monitoring points were added, the increased monitoring rate of DN700-1 800 pipe sections raised from 78.6% to 100%, and the important pipe sections were monitored first.
