The invention provides a detection device for a merging unit based on analog input. The detection device comprises an input component, a standard clock component, an ARM chip, a signal source and a network message analyzer. The input component is connected with the ARM chip and used for sending a command signal to the ARM chip. The standard clock component is connected with the ARM chip and used for sending a standard clock to the ARM chip. The ARM chip is respectively connected with the signal source and the merging unit to be detected and used for sending a pulse per second to the merging unit to be detected and sending signal parameters and a digital signal to the signal source. The signal source is connected with the merging unit to be detected and used for receiving the signal parameters and sending a standard signal to the merging unit and the ARM chip according to the signal parameters and the digital signal. The network message analyzer is connected with the merging unit to be detected. Precision detection, ECT / EVT communication interface detection, sampling value output interface performance detection, clock synchronous detection and network environment influence detection of the merging unit can be rapidly and accurately achieved.
Description
technical field [0001] The present invention relates to the technical field of detection of intelligent electronic equipment, in particular to the detection technology of a merging unit in an intelligent electronic device, specifically a detection device based on an analog input merging unit. Background technique [0002] With the rapid development of smart grid technology, there are more and more digital substations. Due to the use of optical fiber for digital transmission in digital substations, there is no secondary voltage drop and AD acquisition error of analog energy meters, which greatly reduces the error of traditional metering secondary circuits. Digitalization is the direction of electric power development in the world today. [0003] As a bridge from the analog world to the digital world, the electronic transformer plays an important role in the digital substation. It can be considered that the electronic transformer is the cornerstone of the digital substation. ...
