Abstract
The utility model discloses a multifunctional power meter with two communication interfaces, and solves the problem that the conventional working demand is difficult to meet because the conventional multifunctional power meter is only provided with one communication interface. The multifunctional power meter comprises a controller and communication modules, wherein a plurality of communication interfaces are formed on the controller; the number of communication modules corresponds to the number of communication interfaces of the controller; the communication modules are connected with the controller and used for uploading relevant electric parameters to a background of a personal computer (PC); and the controller can implement that two computes can read the data at the same time. The multifunctional power meter has the beneficial effects that one of the communication interfaces can be used for monitoring the site, and the other communication interface are standby or used for acquiring data by other host computers. The multifunctional power meter consists of a plurality of completely independent communication functional modules integrated on the same power meter and has the characteristics of simplicity and convenience in use, low cost, convenience in debugging and assembly and the like.
