Double-MCU scheme building-block application program upgradeable intelligent ammeter

Abstract

The invention provides a double-MCU scheme building-block application program upgradeable intelligent ammeter and belongs to the field of power equipment. The upgradeable intelligent ammeter comprises a first microcontroller and a second microcontroller communicated with the first microcontroller through an asynchronous transreceiver transmitter. The first microcontroller and the second microcontroller are respectively provided with a communication port; the communication port of the first microcontroller is connected with a fixation function module; and the communication port of the second microcontroller is connected with a detachable module. The MCU for realizing a legal measurement function and the MCU for realizing an additional function are physically isolated to enable the legal measurement function and the additional function to be isolated mutually; and on the basis of ensuring the basic stable measurement function of the intelligent ammeter, functions of the detachable module can be added or deleted selectively according to actual use conditions, so that the intelligent ammeter cannot be eliminated for a rather long time, the service life of the ammeter is prolonged, and ammeter replacing cost of a power enterprise is reduced.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a dual-MCU scheme building block application program upgradeable smart electric energy meter. Background technique [0002] With the development of Internet technology, the electric energy meters used in the electric power industry have almost changed from the original mechanical electric energy meters to smart electric meters. The latter has a shorter update cycle, and the smart meter can have more functions through the update program. [0003] Due to the rapid development of current technology, the installed smart meters will be eliminated in a short period of time due to backward functions, which will virtually increase the operating costs of power companies. Contents of the invention [0004] In order to solve the shortcomings and deficiencies in the prior art, the present invention provides a dual-MCU scheme building block application program upgradeable smar...
