Why do old houses need to be retrofitted with remote meter reading smart meters?
The development of power grid towards intelligent terminals and the comprehensive promotion of remote smart meters are the general trend. Residential communities in many places have begun to fully replace smart meters with remote prepaid meter reading systems to achieve intelligent electricity management such as remote reading of meter data, remote prepayment by mobile phone, and remote valve control, solving the problems of low efficiency, long time consumption, and high labor costs of traditional meter reading and payment. However, some old houses still use traditional electricity management modes such as door-to-door meter reading, offline payment, and electricity consumption before charging. The work efficiency is far behind the current era of rapid development of big data. The transformation of old house meters is actually very simple. Replace smart meters with remote meter reading systems to easily achieve remote meter reading.
1.What is a smart electricity meter?
First, let's understand what a smart electricity meter is. Smart electricity meters are one of the basic devices for smart grid data collection. In addition to the basic electricity consumption metering function of traditional electricity meters, in order to adapt to the use of smart grids and new energy, they also have two-way multi-rate metering functions, user-side control functions, two-way data communication functions with multiple data transmission modes, anti-electricity theft functions and other intelligent functions, which basically meet the needs of house power management.
To realize remote meter reading, smart meters need to use the IoT technology, collection-transmission-analysis-application. The collection device collects meter data and then transmits the data to the remote prepaid meter reading system, which then automatically feeds back the information according to the instructions. Therefore, the process of remote meter reading by smart meters is actually a data transmission process.
2.Recommended meter reading solutions
The first is the most cost-saving RS-485 remote meter reading solution. Smart meters all have built-in RS-485 interfaces, so there is no need to build in expensive communication modules, and the meter hardware price is low. However, because RS-485 requires wiring, in order to save communication lines and construction costs, this solution is usually suitable for centralized installation of community meters.
The second is the carrier communication solution. The carrier is divided into half-load and full-load. Half-load is to use a 485 meter plus a carrier collector. No additional wiring is required, and the overall solution is affordable. Full-load means that the meter has a built-in communication module and direct wireless communication. The cost of this type of meter is relatively high.
3.Remote prepaid meter reading system
With smart meters and meter reading solutions, the remote prepaid meter reading system can be used to quickly and accurately generate visual electricity consumption data statistical analysis reports through 4G wireless networking technology. The prepaid meter reading system also provides equipment safety early warning management, remote valve control, power quality display, efficiency operation statistics and other functions. Managers can monitor and manage data through PCs, mobile phones, and keep track of the electricity consumption patterns in the management area at any time, thereby achieving efficient power management.
In addition, there is no need to worry about the price of the remote meter reading system. Because when users purchase the company's smart meters, they can get a free remote prepaid meter reading system. It helps users to read meter data remotely, saying goodbye to manual door-to-door meter reading and saving the cost of manual reading; prepaid mode solves the pressure of advance payment; supports mobile phone remote payment and cash payment; remote valve control, payment closing call, arrears tripping and power outage, to prevent defaulters from not paying their bills.
