Description of the Invention The present invention relates to the field of power meter reading, and more particularly to a meter reading method based on a two-dimensional code.
Background of the Invention In May 2009, the State Grid released the “Strong Smart Grid†research report and put forward the connotation of the development of a strong smart grid. It is based on a strong network shelf, supported by an information and communication platform, and realized by intelligent control. The highly integrated integration of "power flow, information flow, and business flow" is a strong, reliable, cost-effective, transparent, open, friendly and interactive modern power grid. A unified and strong smart grid with the characteristics of information, digitization, automation, and interaction.
Relatively speaking, at present, the main methods of power meter reading in China are remote wireless meter reading, infrared meter reading, and manual meter reading. This method has the following defects: 1. The response is not timely. 2. Resource scheduling is irrational and resources are wasted. 3, long meter reading period. 4, the wireless meter reading traffic cost is too large. 5, data security can not be guaranteed. Two-dimensional code meter reading technology can solve these problems.
Summary of the Invention The object of the present invention is to provide a power meter reading system based on a two-dimensional code and a method thereof in view of the above problems. 
Structural diagram of the present invention
Mainly based on the technology research of remote meter reading of two-dimensional code, it provides a new method for smart meter reading of power system. It successfully develops remote meter reading technology based on two-dimensional code, and provides systematic research and development for new intelligent power grid advanced metering. platform.
The technical solution of the present invention is:
A power meter reading system based on a two-dimensional code, which comprises a plurality of electricity meters, a plurality of concentrators with communication functions, a plurality of portable mobile terminals, and a background service control terminal, wherein the electricity meters are used for electricity metering and will The measurement data is converted into a two-dimensional code tag. The signal output ends of multiple meters are respectively connected to the corresponding signal input ends of the concentrators. The signal output ends of each concentrator are respectively connected wirelessly by the background service control end, and the two-dimensional electricity meter is sent. A plurality of portable mobile terminals are hand-held by each meter reading person, each portable mobile terminal obtains a two-dimensional code tag from the electricity meter, each portable mobile terminal is wirelessly connected with a background service control terminal, and transmits a two-dimensional code label of the electricity meter. The background server control end parses each two-dimensional code tag to read the metering data of each meter and stores it in the database.
The meter of the present invention includes a metering chip and a two-dimensional code generator connected thereto. The metering chip is used for electricity metering. The two-dimensional code generator can encode the meter metering information and the meter in the corresponding connected concentrator. And the address code of the concentrator connected to the electricity meter is converted into a two-dimensional code tag and dynamically displayed. The two-dimensional code tag has a unique physical address.
The portable mobile terminal of the present invention includes a terminal processor and a camera, an infrared scanner, and a communication module connected thereto. The camera and the infrared scanner are used to acquire a two-dimensional code label displayed on a measuring device and sent to the terminal processor. The terminal processor wirelessly connects with the background service control terminal through the communication module to send a two-dimensional code tag.
When the present invention is used, in the urban area or in the area where the signal is strong, the concentrator wireless remote uploading method can be selected, so that the two-dimensional code can be read promptly, accurately, and accurately; in rural areas or areas where the signal is weak, You can choose to use a portable mobile terminal to scan the two-dimensional code information of the meter and upload it to the background service system. In this way, it can not only solve the problem of low meter reading success rate, but also guarantee data security.
The invention adopts physical address automatic addressing, can solve the technical problem of concurrence of large amount of data efficiently, and obtains relevant measurement points, time, data type and other information according to the block address reflection. This program subverts the traditional way of copying, and the simultaneous acquisition of huge amounts of data has fundamentally improved performance and efficiency.
The invention adopts two-dimensional code to store information, which is a kind of high-density coding and has a large information capacity and can effectively solve the problems caused by the excessively long messages. For the acquisition system, the performance will be qualitatively improved. In some blind spots, mobile devices such as mobile phones can be used to scan and upload the meter, which can greatly increase the efficiency and success rate of the collection.
The system of the present invention can also upload the error-producing log to the back-end system through wireless in the form of a two-dimensional code, which greatly improves the efficiency of troubleshooting.
