Abstract

The invention discloses a handheld secondary circuit tester based on an Xilinx operating system. Thehandheld secondary circuit tester comprises an upper shell and a lower shell which can be buckled together, wherein a touch screen is arranged on the upper shell, an SOC main control board, an input and output terminal board, a power supply circuit board and a battery are arranged in the lower shell, the touch screen is connected with the SOC main control board through a hardware FPC flexible flat cable, the input and output terminal board is connected with the SOC main control board through a PC flexible flat cable, and the battery is connected with the power supply circuit board through a 3.96 terminal flat cable. The problems that a secondary circuit tester in the prior art is large in size, unstable in communication, low in precision, low in working efficiency and the like are solved.

Description

technical field [0001] The invention relates to the technical field of test instruments, in particular to a hand-held secondary circuit tester based on an Xlinx operating system. Background technique [0002] At present, the secondary circuit tester uses a discrete CPU device, which occupies a large board area, the data throughput rate between the CPUs is low, and the resources cannot be fully utilized; There are many types of tools and instruments required for work scenarios such as investigation and emergency repair, which are inconvenient to use. In the field work, it is often necessary to carry bulky and heavy items such as batteries, relay testers, permanent magnet emergency operation boxes, and even diesel generators that are inconvenient to carry. Items bring great inconvenience and trouble to actual work efficiency. [0003] Due to the uneven development level of distribution automation in the world and the different development routes, there is no general test tech...
