A security event recording method, device and system

Abstract

A method for recording a safety event, comprising: simultaneously sampling voltage and current, sampling two complete cycles in sequence, namely a first cycle and a second cycle; determining a current cycle and a reference cycle, the reference cycle being the previous cycle of the current cycle , the initial value of the current cycle is set to the second cycle; based on the current cycle and the reference cycle, determine whether there is any event in the upper limit of the voltage, the lower limit of the voltage, the upper limit of the current, the lower limit of the current, the voltage fluctuation or the current fluctuation. When any kind of event exists, execute the safety event recording to generate the safety event recording file and send it to the server. When any kind of event does not exist, continue to sample the next cycle and set the current cycle to return to the previous step. The method disclosed in the present application can solve the problem in the prior art that the terminal user needs a special device for recording the security event in order to realize the function of recording the security event. The present application also discloses a security event recording terminal device and a security event recording system correspondingly.

Description

technical field [0001] The present application generally relates to the technical field of power systems, and specifically relates to a method, device and system for recording a security event. Background technique [0002] The development of Internet of Things technology has continuously improved the informatization level of end users in the power system, enabling digital power operation and maintenance, thereby reducing operation and maintenance costs and preventing accidents. However, at present, a large number of electricity meters or electricity data detectors used in the vast number of power end users, such as factories, parks, office buildings, commercial complexes, etc., have no safety event recording function. However, the equipment that includes the security event recording function on the market is more expensive and requires professionals to design different parameters for different applications. Therefore, on the power lines of general end users, if there is no...
