[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, I will introduce a national invention-invented patent - a multi-information information acquisition system. The patent was applied by State Grid Shanghai Electric Power Co., Ltd., and was authorized to issue an announcement on December 8, 2017.
Content Description
The invention relates to the technical field of measuring instruments, in particular to a multi-table unified information collecting system.
Background of the invention
All along, water, electricity, gas, and warmth are four important energy industries related to people's livelihood, involving millions of households. Among them, meter reading involves a lot of manpower and material resources. At present, the power supply company has built a power consumption information collection system, and has realized the remote acquisition and command delivery of the power meter data. However, meter readings for water, natural gas, and heating are still mainly based on manual copying, which is inconsistent with the construction of smart cities that are being vigorously promoted. For areas that are not centrally heated, it is mainly necessary to collect information on water, electricity, and gas meters. This is an urgent problem that needs to be solved.
Summary of the Invention
The purpose of the present invention is to provide a multi-table integrated information acquisition system in order to overcome the deficiencies of the prior art mentioned above.
The drawing is a schematic diagram of the system structure of the present invention.
A multi-table integrated information acquisition system includes a front-end machine, a concentrator, and a collection terminal connected in sequence. The front-end machine is connected to an electricity information collection system and a user information management system, and the collection terminal is connected to a power meter. Water meters, gas meters, user terminals and household appliances. The user terminal includes a mobile phone and a computer, and is connected to the collection terminal by wireless means. The home appliance includes a refrigerator, an air conditioner, and communicates with the collection terminal through power line communication. The front-end computer communicates with the power consumption information collection system and the user information management system through the TCP/IP protocol. The concentrator communicates with the FEP through GPRS, WCDMA, Ethernet or power optics. The acquisition terminal is connected to the concentrator via an RS485 bus. The power meter is connected to the acquisition terminal via an RS485 bus. The gas meter is connected to the acquisition terminal via an M-Bus bus. The meter is connected to the acquisition terminal via an M-Bus bus. The water meter is a passive direct reading water meter.
Compared with the prior art, the present invention has the following advantages: 1. The user terminal can understand the usage of electricity, water, and gas in the home at any time through the collection terminal, and can obtain the power consumption of the main appliances such as the home refrigerator and air conditioner, and perform intelligence. Control, while improving user experience, can lead people to more energy-efficient lifestyles. 2. The collection terminal uses wired communication to communicate with the meter, the channel is stable and reliable, and the collection success rate is high, which enables the unified collection and management of electricity, water, and gas data. 3. The collection terminal has a high degree of integration, which effectively reduces the equipment sharing costs and maintenance costs at the metering point. 4. The M-Bus communication method can supply power to the water meter, or use a passive direct-reading water meter, which can effectively solve the problems of battery replacement in the later period.
