公共下水道系统的运营和维护是运营商的关键任务。状况评估通常通过传统的闭路电视（CCTV）检查进行。然而，如今可以使用诸如沙井变焦相机 (MZC) 和声学技术 SewerBatt (R) 等替代工具。 INNOKANIS 项目通过三个 MZC 模型和 SewerBatt (R) 来研究下水道系统的结构和运行状况评估，以开发一种光学和声学组合设备，作为传统闭路电视检查的经济高效替代方案。正在进行的项目的第一次现场试验于 2011 年在奥地利进行。根据 EN 13508-2/A1 对 640 种条件进行了调查，并与传统的闭路电视报告进行了比较。计算了两种设备的单独和组合检测率。根据目前的研究结果，MZC 和 SewerBatt (R) 都是传统闭路电视检查的有效替代方案。此外，当两种设备结合使用时，性能会显着增强。
Operation and maintenance of the public sewer system represent key tasks for an operator. Condition assessment is usually conducted by conventional closed circuit television (CCTV) inspection. However, alternative tools such as manhole-zoom cameras (MZCs) and the acoustic technology SewerBatt (R) are available today. The INNOKANIS project investigates structural and operational condition assessment in the sewer system by means of three MZC models and SewerBatt (R) to develop a combined optical and acoustic device as a cost-effective alternative to conventional CCTV inspection. The first field trials of the ongoing project were conducted in Austria in 2011. 640 conditions according to EN 13508-2/A1 were investigated and compared against conventional CCTV reports. Individual and combined detection rates for both devices were calculated. Based on the current findings, both MZC and SewerBatt (R) are effective alternatives to conventional CCTV inspection. In addition, performance is significantly enhanced when both devices are used in combination.
