The invention provides an electric charge data processing system. The electric charge data processing system comprises a data centralized controller, a public network server, a WEB client and a clientdata processing unit. The user side data processing unit comprises a meter reading device, a central processing unit, a storage module and a wireless signal transmission module. The meter reading device, the storage module and the wireless signal transmission module are respectively connected with the central processing unit. The data centralized controller and the WEB client are connected with the public network server through a network. The public network server is also connected with mobile terminals held by power consumers through a wireless network, and the mobile terminals are in one-to-one correspondence with the power consumers. The input end of the mobile terminal is connected with the output end of the WEB client through a wireless network. The meter reading device is used for collecting ammeter data of a user ammeter. According to the scheme, the meter reading speed of workers of a power supply company is increased, and the convenience of searching the power consumption data of the power consumer is improved.
