Energy and resource companies, supplying such as electricity, water, gas, and heat power, have their independent centralized information collection systems, and from a review of customers, these software and hardware duplications cause a great waste of resources, increase the operation and maintenance cost, as well, heaven the workload. In order to address these issues, a feasibility of merging four centralized meter reading systems for respectively electricity, water, gas, and heat, into only one platform was proposed. By a summary of the work in the field, it is shown that conventional “four meters in one” constructions depend on the coordination of responsibilities, as well as rights, among different supply companies. Only with a good implementation guided by the government, the “four meters in one” system can be built. The survey also shows that by developing a smart energy gateway at XX electric power company, the coordination difficulties encountered in the past “four meters in one” constructions are avoided, which provides new ideas for resolving such issues. Possibilities including a wide collection of living demand data and expansion of the functionality of the smart energy gateway are suggested in order to achieve better metrological supports for comprehensive energy and energy internet measurements.
