4.2. RESULTS AND BENEFITS This intelligent system can efficiently and accurately collect the real-time data and then transmit it to a unified information platform. The interval of data collecting can be as short as 2 seconds. Using this method can reduce dependence on labor work and avoid data difference caused by personal interference and field cross- operation, thus ensuing the data collected in time and in high accuracy. Take one test section for example, as shown in figure 4. The cooling intelligent temperature control curves have the following characteristics: (1) compared to the highest temperature value and the point in time of the manually controlled concrete sections, the results of the intelligent controlled sections are basically the same, showing that the intelligent method can effectively control the designed highest temperature; (2) intelligent controlled curves are more smooth and continuous, proving that the data is real-time and the system can coordinate the temperature change; (3) compared to the manually controlled curve, the intelligent controlled one is more fluctuated of flow. This is because the intelligent control platform adjusts the flow size according to the real-time concrete temperature and the entire flow is more saving than that of the traditional method. （a） 23#67 cooling water temperature curve of inlet and outlet (b) 23#67 internal cooling water temperature curve Fig. 4 Cooling intelligent temperature control curves of 23 # 67 of dam[9] 5. CONCLUSIONS The intelligent cooling control system for mass concrete achieves the online, real-time, intelligent acquisition and control during the operation. It can analyze and control water temperature, flow size and direction as required and provides scientific support for exact, procedural and individual management and control of quality of dam concrete. Through the preliminary application test, the method, which is based on real-time variation of concrete temperature and combined with control of water temperature at the import and export of the cooling pipe, has got 1296
