Content Description

The invention relates to a remote meter reading, in particular to a multi-table combined remote meter reading system.

Background of the invention

Water, electricity and gas are three important energy industries related to people's livelihood, involving millions of households. The collection of the three data occupies the time of the people, and the meter reading work also involves a lot of manpower and material resources, and it also shows a variety of practical work. Disadvantages. The intelligent, systematic, and networked residential community has become the development direction of domestic residential construction. Remote meter reading is listed as the basic configuration of intelligent residential communities. In particular, with the development of economy and society, people’s demands for service quality are increasing. The higher, the existing power companies, water plants and gas companies copy their watches. This traditional way of meter reading can no longer meet the needs of modern society. Moreover, in the context of the era of big data, smart, intensive, and networked water, electricity, and gas integration work is conducive to the integration and utilization of social resources.

In China, tap water, gas, and power companies belong to different industries and are under the jurisdiction of different government agencies. Therefore, in order to achieve unified collection of the three tables, it is necessary to coordinate and negotiate among the three companies under unified coordination to determine the pilot communities and conduct on-site visits. Equipment modification and debugging work, and mutual exchange of experience and effectiveness in the acquisition system construction. Under the guidance of relevant national policies and under the guidance of the government, we will jointly build a resource sharing platform. For the three companies, if the remote metering channels and data analysis systems for each meter are established, the duplicate investment will be wasted. Theoretically, if they achieve far-separation, they will create three times more investment and construction workload. For residents, with the deepening of resource sharing, they can enjoy the convenience of real-time remote query of “water, electricity, and gas”, facilitate payment, and increase the transparency of social services. Visible, whether it is for the relevant government management agencies, related companies, or ordinary people, this is a very useful thing.

In addition, heat meters are also used in many places, so the goal is to harmonize the data of water meters, electricity meters, gas meters, and heat meters and perform remote meter readings. In summary, if a system capable of integrating multiple tables can be proposed, integrating multi-table data together for remote meter reading will save the capital construction funds for water meters, electricity meters, gas meters and hot meters, and simplify the meter reading process. .

Summary of the Invention

To solve the above problems, the present invention provides a multi-meter-in-one remote meter reading system, which can implement remote meter reading for water meters, electricity meters, gas meters, and heat meters simultaneously without reading the meters one by one, and does not need to refer to a single table. The construction of a remote meter reading system also saves manpower costs associated with meter reading.

Figure shows the system structure of the present invention

The technical solution provided by the present invention is: a multi-meter-in-one remote meter reading system, including a GPRS public network, a protocol converter, a concentrator, a smart energy meter, a smart water meter, a smart gas meter, and a smart heat meter; an intelligent water meter and a smart gas meter Both the smart heat meter and the protocol converter are connected. The protocol converter and the smart energy meter are connected with the concentrator. The concentrator is connected with the GPRS public network. The protocol converter is used to receive the uplink data of smart water meter, smart gas meter and smart heat meter. It converts the protocol into a protocol consistent with the uplink data of the smart energy meter, and transmits the unified uplink data of the protocol to the concentrator; the concentrator is used to transmit the unified data of the protocol output from the protocol converter to the GPRS public network and integrates the intelligence. The uplink data of the energy meter is also transmitted to the GPRS public network; the protocol converter converts the upstream data of the smart water meter, the smart gas meter and the smart heat meter into the power carrier consistent with the uplink data stat of the smart energy meter, so that the concentrator reads the intelligence. The data information of water meters, smart gas meters, and smart heat meters, and the electrons transferred from the concentrator to the smart meter The carrier is received and transmitted to the GPRS public network.

Among them, the protocol converter converts the data of different protocols into data of a unified protocol, and the concentrator sends all the data to the GPRS public network after being collected for remote meter reading. With the present invention, it is not necessary to individually perform meter readings on smart water meters, smart gas meters, smart heat meters, and smart energy meters one by one, and it is not necessary to build a remote meter reading system on a single table. Only one system is required to simultaneously perform smart meter and smart meter. Gas meters, smart heat meters, and smart meters perform meter reading and save considerable labor costs. They also include supercapacitors, supercapacitors, smart water meters, smart gas meters, smart heat meters, and smart energy meters, and supercapacitors.
