世界各地的500多家废物到能源厂展示了公司规划，工程和调试复杂系统的能力。Hitachi Zosen Inova最近测试了一个新的过程监控解决方案：来自的模块化无线网状传感器网络平台Paradox Engineering(www.pdxeng.ch).
The monitoring of process parameters is of major importance after the start up of a new plant, when systems have to be optimized. Distances within the plant are often long, which makes the troubleshooting and testing of operations complex and time consuming, and operating conditions are extreme: high temperatures, thick concrete walls, steam, etc. Hitachi Zosen Inova conducted a test to verify the reliability of Paradox Engineering’s PE.WSNi industrial sensor network in the plant in Lausanne.
The Hitachi Zosen Inova solution involved one PE.WSNi gateway and three nodes, one I/O module with two 4-20mA channels connected to radiation pyrometers, three I/O modules with two 4-20mA connections to four thermometers, one flow sensor, one pressure sensor, and one I/O module with two 4-20mA channels connected to two thermometers.
According to Gianni Minetti, CEO at Paradox Engineering, “The PE.WSNi node was installed in the waste bunker and attached to two microwave radar level measurement devices via 4-20 mA transmitters. The PE.WSNi gateway was installed in the plant control room, which was separated from the bunker through a thick concrete wall. The gateway stored one-minute level measurements of the waste level in the feed hopper. In this test phase, data were downloaded into .csv format and used, firstly, as indicators of the system reliability and secondarily for statistics and monitoring.”
MINETTI表示，Martin Steiner，Hitachi Zosen Inova研发项目经理的期望，以及项目工程工具经理的Urs Hugentobler，“与Swift和Easy System Monity监控和成本减少相关，以及能够超越本地数据收集获得下一级数据渗透和测量。“
After a smooth installation phase, the test gave positive results, said Minetti. The only obstacle was the two 4-20mA analog input channels on the I/O module that were not galvanically separated. To overcome this, it was enough to pay particular attention to the connection of external power supplies, and the problem was solved using a second 24V supply.
Steiner says, “For troubleshooting and optimization, PE.WSNi allows us to monitor important parameters of the system in a very easy way. It allows us to reduce the costs for experimental installations for R&D projects, enabling us to avoid cables and local data collection.”
在第一个测试阶段成功之后，Hitachi Zosen Inova已经决定实施第二个测试。PE.WSNI将与日立Zosen Inova的数据分析工具集成，称为Pamela，该工具将研究如何减轻废物到能量锅炉中的污垢。这次，分析将考虑来自热电偶，流量传感器和压力传感器的数据 - 一种更复杂的信息集和更具挑战性的工作环境。
