Application keywords of Ruigu Technology in remote power meter reading,/,
Overview
With the development of industrial automation, remote meter reading has become an important part of the smart grid system. Nowadays, people have higher requirements for power supply. With continuous improvement, remote meter reading has gradually replaced the early manual meter reading. Today, when wireless mobile communications are widely used, the remote meter reading system using /network not only has wide coverage, low communication cost, and can read data remotely in an efficient and real-time manner, but can also improve the management planning of the meter reading business of power units. It solves the problem of scattered distribution points and difficulty in management. It is an ideal power meter reading solution for power-related units.
System Composition
The remote meter reading system consists of three parts: meter terminal, wireless transmission terminal equipment (Ruigu), and data center. The meter terminal is connected to (Ruigu) through the /interface to realize data transmission. The operator network establishes a connection and transmits data to the meter reading center through wireless/network to implement a remote meter reading system.

2. Main functional features of the system
Meter terminal
Read Get the user's power consumption data, send the data to it through the / interface, and respond to the external reading command. The electric meter terminal includes an electric meter, a power display instrument, a power collector, etc. The electric meter terminal has a built-in microcontroller and configuration/interface.
Wireless transmission terminal
By establishing a network communication link with the operator's network, it realizes the function of transmitting the power data received by the meter terminal to the meter reading data center. The wireless transmission terminal in the system adopts Ruigu, Rui Gu has two operating modes
Always online mode is always online after power on. The data center can perform remote meter reading at any time with strong real-time performance. The online mode is generally suitable for occasions that require frequent meter reading and data reading. .
Only when the online mode is triggered, the meter terminal starts to go online when there is data upload or when the data center receives a meter reading SMS command. The triggered online mode is generally suitable for occasions with low meter reading frequency. It has low power consumption and can save the traffic costs generated by transmission.
Data Center
Establish a connection through the wireless network and read the power data from the meter terminal to achieve remote meter reading.
Typical Applications
Tap water remote meter reading is the same as electricity. With the development of industrial automation, early manual water meter reading data has gradually been eliminated, replaced by wireless/network remote meter reading systems. The remote meter reading system consists of three parts: a water meter terminal, a wireless transmission terminal (Ruigu), and a data center. The water meter terminal is connected to (Ruigu) through/interface to realize data transmission, establishes a connection with the operator's network, and transmits through wireless/network The data is sent to the meter reading center to implement a remote meter reading system.
Electricity meter reading, tap water meter reading, natural gas meter reading, transmission pipeline meter reading, etc. are all typical solutions for remote meter reading.
The system solution design is basically the same. It is also a typical application solution.
