| In the growing demand for energy, while energy supply is becoming increasingly tense, prices continue to rise. This makes the energy consumption cost play a more and more proportion in the enterprise cost calculation. To improve the energy utilization rate, cement enterprises, basic industries and traditional industry in China,take various optimization reconstruction and energy conservation plan. To begin with, we need to find processes with unreasonable energy utilization. This needs statistical analysis for energy consumption status of enterprises and search in energy-saving potential of each link.Based on the analyzation of energy structure and energy consumption characteristics in the complete cement production process, this paper completed the following work. First of all, determine the method to choose the energy data monitoring stations. Secondly, propose the whole scheme design of energy data acquisition system with fully-function and universality. Thirdly, finish the design of each function module, such as the serial communication module, the OPC communication module and the analysis module. Fourthly, finish writing the software program of the system which provides basic information for the statistics, analysis and forecast of the power consumption and other resources’ consumption in cement enterprises, so that enterprises can have an intuitive understanding of their energy consumption. Finally, this energy data acquisition system was successfully used in six cement enterprises belong to a building materials group and played an important role in finding out the weak link of the enterprise, reducing costs, reducing energy consumption, improving economic performance and providing the theoretical basis and objectives for the enterprise to develop energy saving plan. |
