Portable field power consumption inspection device and power consumption data acquisition method

The invention relates to a portable field power consumption inspection device and a power consumption data acquisition method. The portable field power consumption inspection device is characterized in that a central processor is connected with a touch screen, a color TFT display screen, a wireless and cable data carrier module, a power supply management module and a user information acquisition module; the user information acquisition module is connected with an external expansion drive module. The customer basic information in an electric power informatization system is regularly led in, so that the field inquiry can be conveniently realized, and the inconvenience of carrying a plurality of work orders on site can be avoided. Meanwhile, under the situation that the customer on-site equipment is changed, data can be recorded in the on-site power consumption inspection device of the portable device, by implementing the design of a communication conversion module circuit, the noncontact acquisition of on-site data can be realized for the on-site cable acquisition data, then the on-site data is led into the electric power informatization system, the system can be updated in real time, and reading of an electric energy meter can be carried out by utilizing infrared rays or RS485, so that convenience and error in manual meter reading can be avoided, and comparison can be carried out in time.
