Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The invention discloses a kind of affair sequential record method, as it is shown in figure 1, the method at least comprises the following steps:
S11: sequence of events recording device periodic scan controls the on off state of field apparatus; Wherein, above-mentioned sequence of events recording device is connected with the switch controlling field apparatus;
Concrete, a sequence of events recording device can specifically be connected with 12 switches controlling field apparatus, is certainly not limited to above-mentioned quantity, and its staff according to the practical situation controlling on-the-spot and above-mentioned sequence of events recording device, can be allocated;
S12: when sequence of events recording device scan on off state change time, the on off state that changes of record and time;
Concrete, the change of above-mentioned on off state includes being become the change of negative level from positive level and being become the change of positive level from negative level;
Therefore, in embodiments of the present invention, owing to sequence of events recording device periodic scan can control the on off state of field apparatus, and when scanning on off state and changing, it is possible on off state that record changes and time; Therefore, the method adopting the present invention, it is possible to achieve the monitoring of facility switching state and record.
Due to, in actual applications, an event sequence note puts the limited amount of the on off state that device can monitor and record, and therefore, when the on off state need to monitored and record is more, can arrange multiple sequence of events recording device;And the time of above-mentioned different event sequence recorder needs to keep consistent; Therefore, in other embodiments of the present invention, when the quantity of the sequence of events recording device in above-mentioned all embodiments is more than 1, as in figure 2 it is shown, said method also includes:

S32: sequence of events recording device checks calibration time and second time of the last acquisition;
S33: sequence of events recording device utilizes the calibration time of the last time, the second time and the 3rd time, it is thus achieved that the standard time of above-mentioned sequence of events recording device;
Concrete, above-mentioned steps S33 may particularly include:
By the 3rd time and worst once obtain second time catch cropping poor, it is thus achieved that the second object time;
During by the second object time and the last calibration catch cropping and, it is thus achieved that and record the standard time of above-mentioned sequence of events recording device;
S34: record standard time and the on off state changed;
Therefore, adopt aforesaid way, the on-off state transformation period that each sequence of events recording device records can be made almost to be the time (error is less than 1ms) of clock reference device, thus embodying the change order of different on off state more accurately, and then when a failure occurs, it is more beneficial for the reason of host computer analysis accident, solution more accurately may finally be proposed.
