1. System Overview
The network prepayment system is based on intelligent instrument technology, Internet technology, IT technology and communication technology. With the help of terminal prepayment meter, it realizes online monitoring and management of energy consumption, and realizes property payment management by means of "paying first, using energy later, and cutting off power in arrears". The system adopts unified management of water and electricity billing, payment before energy consumption, low balance alarm, cardless network recharge, remote closing control, and a combination of management functions such as malicious load monitoring, centralized energy-saving control, and terminal energy consumption monitoring, effectively solving the problems of difficult meter reading and charging in commercial buildings. It not only saves property management costs, but also reduces the waiting time for users to queue up for payment, improves service level, and facilitates the centralized and effective control of energy consumption by management departments for student apartments and commercial and residential tenants.
