The control device 200 may include a Remote Terminal Unit (RTU), a Distributed Control System (DCS), or the like. The control device 200 can be used to monitor the monitoring parameters collected by the collection device 100 in real time, and control the alarm device 400 to output alarm information, and can also be used to control the operating status of the oil and gas production system. Specifically, the control device 200 may compare the real-time monitoring value of the monitoring parameter with the set alarm threshold, and determine whether the real-time monitoring value exceeds the alarm threshold. When the real-time monitoring value exceeds the alarm threshold, the alarm device 400 is controlled to output alarm information according to the delay timing set by the delay timer 300, so that the operating state of the oil and gas production system can be controlled.

The delay timer 300 can be used to set the alarm delay of the oil and gas production system, which can adopt a delay timer based on the Markov model, so that when only a plurality of monitoring parameters such as 5 consecutive measurement values exceed the corresponding When the alarm threshold is set, the alarm device 400 is triggered to operate. And an activated alarm will be eliminated only when several consecutive measured values are lower than the alarm threshold of the monitoring parameter.

Alarm dead zone is an alarm processing method to reduce alarm nuisance. The specific treatment method is: taking the high alarm as an example, when the alarm is triggered, if the monitoring parameters return to below the alarm threshold, the alarm recovery is not performed immediately, but the alarm recovery is performed after crossing the dead zone. For example, for the dead zone, suppose the alarm threshold of a monitoring parameter ranges from 0.5 to 1 meter, if the dead zone is set to 5% of the range, for high alarm, when the value of the monitoring parameter exceeds 1.05 meters, the alarm occurs, when The alarm will disappear only when the value of the monitoring parameter is lower than 0.95 meters. By setting the alarm dead zone setting device 600, it is possible to avoid repeated triggering of an alarm when the monitoring parameter value fluctuates near the alarm threshold, thereby avoiding the consumption of energy of the operator.
