1) it is installed with web camera on control cabinet, and camera data is transmitted to cloud, with feelings around real-time inspection and control case
Condition, when have personnel close to when sound an alarm: you have entered monitoring area.
2) when improper opening phenomenon occurs in control cabinet chamber door, intelligent controller PLC issues PUSH message to APP and number
According to platform；When there is stealing electricity phenomenon generation, intelligent controller PLC issues clearance order, cuts off pumping unit major loop, is simultaneously emitted by
PUSH message is to APP and data platform.
2, long-range starting problem: intelligent controller PLC can be by APP or the long-range starting of data platform operation, can before starting
Oil well ambient conditions are observed by web camera IPC, after determining without personnel or other risk factors, remote pumping unit major loop of controlling is connect
Logical, phonetic alarm YS issues phonetic warning first after major loop is powered, and prompt: oil well will start, it is noted that safety prompts
After one minute, start pumping unit.
3, pumping problem: well is taken out in oil field between having many oil wells to be, oil recovery N days, stop well N days, needs manual operation, workload
Greatly, this control cabinet can be taken out, and alarmed between automatic before activation by parameter setting, avoid danger.
4, adjust the speed problem: some oil wells need to adjust pumping time, previous method is to pass through since underground oil situation changes
It replaces belt and clump weight cooperates, realize pumping time and velocity variations, workload is huge, and easily causes danger, this control cabinet can lead to
Motor start-up controller parameter setting adjustment motor rotations are crossed, workload is reduced.
5, monitor in real time: since oil field operation area is big, oil well distribution dispersion, oil well operating condition need to pass through patrol personnel
It is fed back after being maked an inspection tour daily to well side, long-range APP may be implemented by the web camera IPC of this control cabinet or data platform is supervised in real time
Control, patrol personnel, which stay indoor, can grasp oil well operating condition and operation data, reduce workload.
