Based on the electricity information acquisition system, the realization of water, gas and heat information acquisition is of great significance to the construction of smart city. This paper presents a power information acquisition system based on fourtable data acquisition. Firstly, the architecture of the electric information acquisition system and the communication technology of electricity, water, gas and heat are proposed. Then, the scheme of constructing the fourtable set copying system is studied. This paper analyzes the collection scheme, feasibility analysis, networking technology and function of the system. In addition, a fuzzy analytic hierarchy process (AHP) is used to comprehensively evaluate the constructed fourtable set copying system. Finally, the construction of the fourtable collecting and copying system was carried out in a district of fujian, and the economic benefit analysis was carried out. The fuzzy comprehensive evaluation method was adopted to calculate the weight of each index, and the final comprehensive evaluation was conducted. The results show that the performance of the modified fourmeter system is greatly improved compared with that before the reform, which proves the practicability of the fourmeter system.
