Security event recording method, device and system

Abstract

A security event recording method comprises the following steps of: simultaneously sampling a voltage and a current, and sequentially sampling two complete cycles, namely a first cycle and a second cycle; determining a current cycle and a reference cycle, the reference cycle being a previous cycle of the current cycle, and the initial value of the current cycle being set as a second cycle; and based on the current cycle and the reference cycle, judging whether any one event of the voltage above the upper limit, the voltage below the lower limit, the current above the upper limit, the current below lower limit, voltage fluctuation or current fluctuation exists or not, when any event exists, executing security event recording to generate a security event recording file and sending the security event recording file to a server, and when any event does not exist, continuing to sample the next cycle, setting the next cycle as the current cycle and returning to the previous step. The methoddisclosed by the invention can solve the problem that in the prior art, a terminal user needs a special device for security event recording to realize a security event recording function. The invention further correspondingly discloses a security event recording terminal device and a security event recording system.

Description

technical field [0001] The present application generally relates to the technical field of power systems, and in particular relates to a method, device and system for recording security incidents. Background technique [0002] The development of Internet of Things technology has continuously improved the informatization level of end users in the power system, which can realize digital power operation and operation and maintenance, thereby reducing operation and maintenance costs and preventing accidents. However, at present, a large number of electric meters or power data detectors used by the majority of electric power end users, such as factories, parks, office buildings, and commercial complexes, do not have the function of recording safety incidents. However, the equipment on the market that includes the security event recording function is more expensive and requires professionals to design different parameters for different applications. Therefore, on the power lines ...
