Clock tester and clock test method for distribution terminals

Abstract

The invention discloses a clock tester and a clock test method of a distribution terminal. The clock tester comprises a digital processing module, a clock module, a GPS module, a communication moduleand an input / output module. The digital processing module is electrically connected with the clock module, the GPS module, the communication module and the input / output module, and the clock module iselectrically connected with the GPS module. The clock module is used for: acquiring the GPS second pulse signal generated by the GPS module; According to the GPS second pulse signal, the crystal oscillator is tamed to obtain the clock signal. Timing the distribution terminal according to the clock signal and the GPS second pulse signal; The digital processing module is used for performing clock test on the time-given distribution terminal through the communication module and / or the in / out module. The clock tester provided by the present application enables the distribution terminal and the clock tester to coincide in time by timing the distribution terminal, so that the clock test is carried out based on the time of the same clock tester, and the accuracy of the clock test is improved.

Description

technical field [0001] The present application relates to the testing field of power distribution terminals, in particular to a clock tester and a clock testing method for power distribution terminals. Background technique [0002] The power distribution terminal is the basic equipment for power distribution automation. It is used to realize the monitoring and data collection of power distribution network equipment. functions such as positioning and recovery. [0003] At each stage of the construction and implementation of the distribution network, all kinds of distribution terminals need to carry out clock tests related to Sequence Of Event (SOE) events, remote signaling response time, and remote control response time. Since the respective clocks of each power distribution terminal in the power distribution network are not the same, the time of each power distribution terminal is also different. The clock test is based on the time of the power distribution terminals. Sinc...
