It can be configured to display different homepage functions, as shown in the following figure [Kanban homepage] [Blank homepage] 【 Equipment Monitoring Homepage - Special Customization 】 ## meter reading management ### electricity meter management Meter management, Real-time View the online status of the meter and electrical parameter data (active energy, current, voltage, power, etc.) View data curve Select a certain instrument to view the Real-time data and data curve of the table. [Instrument file] Add/modify the name, communication address, region, and port of the instrument,Protocol， Parameters such as magnification and base. ### Water meter management Water meter management, similar to electricity meter management function, maintains water meter files and displays water meter status and data. Statistical data and usage curve of water meters ### Regional Management Regional management, maintaining project building floor and other regional information. Provide basic information for water and electricity meters. ### Port management The port management of the collector access system supports three types of access:
• Ordinary serial port: serial port name, baud rate, parity, and other parameters
• Network port: Suitable for non heartbeat versions of the collector, with one port corresponding to one collection serial port.
• Heartbeat packet: suitable for collection with heartbeats. The system can configure the heartbeat packet to be consistent with the heartbeat packet of the collector, which is used to identify the link ## Payment service ### Electricity meter payment Electricity meter cost control management, Real-time meter reading and billing, overdue opening and closing, supports remote opening and closing operations, sets cost control modes and modifies parameters. Remote recharge Detailed payment information ### Water meter payment ### User Profile Manage and maintain user profiles ### Recharge record Record each recharge record [Bill Printing] [Bill Format Setting] ### Deduction Record Daily deduction records are formed, and each deduction is clear and explicit. ### Unit price management Maintain the water and electricity prices of the management system, and customize multiple prices to be associated and bound with water and electricity meters. Supports both single price and multi rate pricing. ### Notification message View SMS sending records and status ## Payment business process ### Add user Add the corresponding user information file to the user profile. ### Account opening usage Taking the water meter as an example, select the water meter, click on "Account Opening", select the user of the instrument, enter the starting usage information and purchase amount, and save the account opening.
