In addition, the system also includes an industrial control cabinet, in which many integrated circuit boards, power supply and switches, Plc modules and other electronic components are installed. 4. CASE OF XILUODU ARCH DAM 4.1. THE TEST AND THE FILED APPLICATION In order to further explore the evolution law of three-dimensional real temperature field of large-volume concrete through water-cooling, and in the same time improve the system based on the site construction environment, the indoor experiment (at Tsinghua university) and field test (at Xiluodu arch dam) are conducted in the early construction period of Xiluodu. After the pre-test, the system was initially applied on a large scale at Xiluodu Site. The site installation in Xiluodu project is shown in figure 3. The system control cabinets are set at different elevations of the left and right banks. Each cabinet controls 50 to 100 units of integrated device of temperature and flow. Take the cabinet installed at EL.527m, on the permanent bridge behind the dam and the corresponding integrated devices for example. The pump station is at EL.559m elevation, involving dam sections from number 21 to 29, and its control elevation is from 510m to 630m. The entire local data is transmitted through a wireless bridge to the platform at elevation of 610m at the right bank. And the platform is connected to the server platform in the rear base through the optical fiber.
