Abstract

The invention relates to a chip development device, and discloses a device for developing a programmable single-phase electric energy metering chip. A function of an electric energy metering chip is realized by a field programmable gate array; an upper computer corrects and controls the field programmable gate array through a singlechip, and can perform downloading and programming repeatedly; and a user can be allowed to repeatedly modify a design of the chip under the condition that a peripheral circuit is not changed, and the performance after the design is modified is tested, so that a development design and a test process are simplified greatly, and the development cost of the cost is reduced greatly. Three paths of input signals are involved; and whether a phenomenon of electricity stealing exists can be judged by comparing two paths of current input signals.

Description

technical field [0001] The invention relates to a chip development device, in particular to a programmable single-phase electric energy metering chip development device. Background technique [0002] As a special chip for electric energy measurement, electric energy metering chip occupies a large proportion in electric energy management instruments, and its performance directly affects the efficiency and technological level of electric energy management. The energy meter is the basis for billing by the power sector, so it is necessary to ensure its performance stability, measurement accuracy and reliability. There are already a large number of electronic energy meters in actual operation. The technical characteristics of the electronic energy meter mainly depend on the characteristics of the energy metering chip, so the research on the metering chip of the electric energy meter has very important economic value and theoretical significance. [0003] The early electric ener...
