Problems solved by technology

However, this scheme has the following problems and can only be used as an alternative under special conditions

[0005] (1) The problem of communication distance: most of the electricity meters are installed in a centralized manner, while most of the water and gas heat meters are installed in a decentralized manner

As a result, there is a certain distance between the electric meter and the water and gas heat meter, and there are many walls in the middle, the wireless communication stability is poor, and the construction and cost cannot be budgeted after adding a wireless repeater.

[0006] (2) Meter interface problem: the multiplexing meter module solution can only be used for "micro-power wireless" or "dual-mode" meter modules, and can only collect wireless water, gas and heat meters

[0007] (3) Wireless parameter problem: the prerequisite for the multiplexing of the wireless module of the meter or the dual-mode module is that the frequency of the wireless part inside the wireless water gas heat meter is similar to that of the wireless part, and the modulation method is the same

[0008] (4) Reuse impact problem: When reusing the meter module, the module must continuously switch the uplink and downlink working modes, and cannot work in the uplink or downlink at the same time, which will inevitably affect the stability of the original power collection

[0009] In addition, the functions of the current master station system for multi-meter integration are not perfect, and there are many other energy supply units with changing demands. It is difficult to use a large and complete single master station to fully meet the refined needs of these units, such as real-time Meter reading, pipe loss statistics, real-time valve control, design operation and maintenance, etc.

Moreover, the power company and other energy supply units may use their own intranets for the construction of the master station, making it difficult to share data from the master station level
