Abstract

The invention provides a PXI bus-based portable intelligent simulation unit, which comprises a PXI case, a network interface board, a time service unit board, an analogue collection board, a switching value input board and an operation loop board, wherein the PXI case, the network interface board and the time service unit board are connected with the analogue collection board, the switching value input board and the operation loop board through a PXI bus. The PXI bus-based portable intelligent simulation unit provided by the invention integrates three functions of a merging unit, an intelligent terminal and a time service unit; a configuration method is relatively simple and convenient; and a simple and convenient test environment is provided for testing of protection and measurement and control devices.

Description

technical field [0001] The invention relates to an analog intelligent unit, in particular to a portable analog intelligent unit based on the PXI bus. Background technique [0002] In smart substations, the commissioning and testing of bay layer equipment often requires the cooperation of multiple sets of equipment to complete. For example, when secondary equipment such as protection and measurement and control of smart substations are debugging single equipment, they need to be connected to the analog sampled value signal SMV, switch input signal (including switch and knife switch position signal, pressure plate signal, etc.), switch Output signal (opening and closing signal of switch and knife switch) and timing signal (generally adopts B code), etc. [0003] At present, the SMV sampling value signal is generally provided by a digital relay protection tester, but the digital protection tester is expensive and the operation is relatively complicated; on the other hand, the ...
