Smart meters alone can't realize the functions of data remote transmission and prepayment. We need prepayment meter management system, so how does prepayment meter management system work? What are its functions? This article answers your questions.

    The smart meter far exceeds the meter reading system, which can be used at any time and any place through the network terminal, such as PC, laptop, iPad tablet and smart phone through the browser terminal. The client can achieve zero maintenance and ensure the real-time communication and security of data.

    Main functions of prepaid electricity meter management system:

    Management function, online query, anti stealing function, mobile payment, report function, online warranty, statistical analysis, remote control, notice and announcement, etc.

    Automatic collection function: according to the set time interval, the collection equipment automatically collects the meter data and stores it locally. At the same time, the master station collects it regularly according to the demand. When the collection fails, each link will automatically perform supplementary collection to ensure the data integrity.

    Remote control: the on-off status of various meters can be controlled manually at any time in the master station according to business rules. For important and urgent operations, customized mobile app can also be provided to complete (such as emergency power transmission).

    Balance alert / reminder notice: the prepayment master station will automatically collect the balance or amount of the meter every day. When the balance is less than 10 days, it will use 3 days (estimated according to the average amount of the last Sunday), automatically generate the alarm information, and send it to the customer's mobile phone via SMS or wechat. The post payment master station will check the overdue bill regularly, and automatically send the reminder SMS and wechat to the customer's mobile phone.

    Overload trip: by detecting the phase change and instantaneous large current change of current passing through a certain dormitory, the power of pure resistance circuit is finally judged and controlled.

    System master architecture:

    The meter transmits the data to the collector through RS485 interface, and then automatically copies the data information to each meter through the concentrator according to the meter reading task of the management center, saves the hour, day and month data information, and uniformly submits it to the management center for centralized processing.

    At present, the remote meter reading of smart meters is much advanced, and our comparative advantage with the traditional one is obvious.

    Background management system interface: the system does not need to install any client, can log in through the browser input web address, client time zero maintenance, to ensure the real-time communication and security of data.
