Embodiment Construction
[0010] Such as figure 1 As shown, in the system composed of the prepaid smart meter 1, the payment device 2 and the low-voltage power line 3, the prepaid smart meter 1 is installed outdoors, and the meter controls the power supply to the user by judging the user’s prepaid balance. Electricity can only be used when the ammeter is recharged, the payment device 2 is used to realize the payment operation, and the low-voltage power line 3 is a channel for electric power and recharge information transmission. The invention mainly solves the problem of the user recharging the prepaid smart meter indoors. The user accesses the payment device 2 in the present invention through the power line interface at any position indoors, and inputs the payment command through the buttons of the payment device 2, and the single-chip microcomputer in the device processes and analyzes the recharge command, and then sends the payment data through the power line carrier communication To the prepaid sm...

The invention relates to a method and device for a user to remotely recharge a smart electricity meter with the prepaid function indoors by using power-line carrier communication. Two-way communication is realized by using the power-line carrier communication technology and the smart electricity meter. A user inputs a recharging command through buttons on the device, a singlechip machine in the device processes and analyzes the recharging command, sends the recharging command to the smart electricity meter by using the low-voltage power-line carrier communication technology and simultaneously receives and displays the feedback information of the smart electricity meter. The invention provides a device for realizing indoor power utilization prepaying for a user. The installation of the device is convenient by using the power-line carrier communication manner, and meanwhile, the AC and DC dual power supply mode ensures the normal display and recharging of the system in the situation that the power line is in a power failure.
Description
technical field [0001] The present invention relates to a method and device for paying for a prepaid smart meter, in particular to a method and device for realizing two-way communication with the smart meter by using power line carrier communication technology and recharging the prepaid smart meter indoors. Background technique [0002] With the development and gradual application of smart grid technology, the use of smart power management systems and smart meters continues to increase. On the one hand, through smart power management systems, power companies can remotely obtain real-time power consumption information of users. On the other hand, users It will also act as a participant in electricity consumption management to realize indoor monitoring and management of household electricity consumption. Among them, an important aspect of household power management is the use of smart meters with prepaid functions. In addition to the metering functions of ordinary power meters...
