In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention also may be implemented in the other embodiments of details.In other situations, it omits to well-known system, device, electricity
The detailed description of road and method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Embodiment one
It is the implementation process schematic diagram of fault wave list updating method provided in this embodiment referring to Fig. 1.The present embodiment
Display equipment of the fault wave list updating method suitable for read failure wave, such as HMI (Human Machine Interface,
Man-machine interface).The embodiment will to show that equipment side illustrates fault wave list updating method, specifically, in the present embodiment,
Fault wave list updating method may comprise steps of:
Step S101 obtains the time identifier of newest fault waveform data in dsp system, every event within a preset period of time
Hinder Wave data and corresponds to a time identifier.
Step S102, judge the newest fault waveform data time identifier and waveform list first address whether
Match, the address of the waveform list is for indicating the time identifier.
Step S103 will be described if the time identifier of the newest fault waveform data and the first address mismatch
The time identifier of newest fault waveform data is stored to the first address of the waveform list.
In practical application, display equipment will refresh waveform list when showing or exporting fault wave in real time, so as to according to wave
The time identifier of the fault wave stored in shape list inquires fault wave.Since fault wave data volume is big, frequently refresh storage in this way
The process of list largely effects on reading and exports the speed of fault wave, influences detection efficiency.Therefore one kind is present embodiments provided
Fault wave list updating method makes to show equipment without the frequent waveform list for refreshing fault wave.
Specifically, fault waveform when DSP real-time storage electric system is broken down, and record that each fault wave occurs when
Between point.It obtains the time point that each fault wave occurs and generates waveform list, i.e., waveform is generated according to the time identifier of each fault wave
