step S430: generating a second logic judgment rule base according to the fourth switch execution rule;
step S440: and obtaining the first safety interlocking rule according to the first logic judgment rule base and the second logic judgment rule base.
Specifically, the first interlock device is one of devices forming a safety interlock rule, the second interlock device is another of devices forming the safety interlock rule, for example, a top rotating casing device and a hydraulic chuck device are mutual interlock devices, the first switch execution rule is that a switch of the first interlock device is on, and a switch of the second interlock device is off; the second switch execution rule is that the switch of the first interlocking device is closed, and the switch of the second interlocking device is open; the third switch execution rule is that the switch of the first interlocking device is closed, and the switch of the second interlocking device is closed; the fourth switch execution rule is that the switch of the first interlock device is on and the switch of the second interlock device is on. The first logic judgment rule base is a rule base with the safety meeting the target condition, and the second logic judgment rule base is a rule base with the safety not meeting the target condition. And the accuracy and the effectiveness of the safety interlocking rule are improved by judging or not based on logic.
Further, the step S500 of determining whether the first execution state satisfies the first safety interlock rule further includes:

The second switch execution state is a real-time state determined according to specific switch parameters in the second control parameters, such as wellhead hydraulic chuck switching actions. Namely, when the safety interlocking device normally works, the switching action (casing engagement/release) function of the rotary casing setting device and the opening and closing action of the wellhead hydraulic chuck are realized, two sets of devices can be in a closed state at the same time but cannot be opened at the same time, namely at least one device is in a closed state all the time, so that accidents are prevented, the condition whether the safety interlocking rules meet can be judged according to the logic, and the logic of execution of the safety interlocking rules is improved.

When the first failure probability is higher, the possibility that the working equipment fails is higher, so that the maintenance is finished corresponding to the preset maintenance frequency, and the technical effect of reducing the failure rate of system valves and improving the stability of the whole control system is achieved.

step S820: and obtaining a first output result of the safety control training model, wherein the first output result is a first safety control coefficient.
Specifically, the first safety control coefficient is input into each set of training data as supervision data for supervision learning, the safety control training model is a model established based on a neural network model, the neural network is an operation model formed by connecting a large number of neurons, and the output of the network is expressed according to a logic strategy of the connection mode of the network. Further, the training process is substantially a supervised learning process, and each of the plurality of sets of training data includes: the safety control training model continuously corrects and adjusts the first pressure adjusting parameter, the second pressure adjusting parameter and identification information for identifying a first output result until the obtained output result is consistent with the identification information, the group of data supervised learning is finished, and the next group of data supervised learning is carried out.
