In use, the input of the data acquisition module 11 and the input of the data transmission module 13 are connected to the top drive control system 19. The communication module 15 is connected with a top drive drilling control optimization device 21. The top drive drilling control assistance device of the present embodiment is thus connected between the top drive control system 19 and the top drive drilling control optimization device 21. Therefore, the top drive drilling control optimization device 21 can automatically read the inherent parameters of the top drive drilling system and automatically adjust the internal control logic according to the inherent parameters, so that the control logic is prevented from being manually modified according to the characteristics of the top drive drilling system, and the working efficiency of the top drive drilling control optimization device 21 can be improved.
Further, when the top drive drilling system works, the data acquisition module 11 can acquire real-time measurement parameters of the top drive drilling system and send the real-time measurement parameters to the communication module 15. The top drive drilling control optimization device 21 can obtain the real-time measurement parameters; and generating a control command according to the real-time measurement parameter. And then the communication module 15 receives the control instruction, and the data sending module 13 sends a control signal to the top drive drilling system according to the control instruction, so as to perform optimal control on the top drive drilling system.
The technical scheme shows that: the top drive drilling control auxiliary device A of the embodiment of the application can automatically modify the control logic according to the characteristics of the top drive drilling system, so that the manual modification of the control logic according to the characteristics of the top drive drilling system is avoided, and the working efficiency can be improved. And the top drive drilling control optimization device 21 can control the top drive drilling system through the top drive drilling control auxiliary device of the embodiment of the application, so that the control of the top drive drilling system can be optimized.
as shown in fig. 1, in the present embodiment, an input of the data acquisition module 11 is for connection to a top drive control system 19. The top drive control system 19 is connected to a top drive drilling system. Therefore, an operator can perform various drilling operations through the operating console of the top drive control system 19 and also can monitor the running state of the top drive drilling system, so that the operating function of the top drive control system 19, and the parameter display and remote monitoring of the top drive drilling system are realized. The input end of the data acquisition module 11 is connected with the top drive control system 19. I.e. the data acquisition module 11 is not directly connected to the top drive drilling system but to the top drive control system 19. Thereby enabling partial functionality of the top drive control system 19 to be opened. The partial functions include, but are not limited to, an upper torque limit setting, an upper speed limit setting, a forward and reverse rotation knob, etc.
In this embodiment, the data acquisition module 11 is used to acquire real-time measurement parameters of the top drive drilling system. The real-time measurement parameters and the real-time measurement parameters collected by the top drive control system 19 belong to a series relation. That is, the real-time measurement parameters acquired by the data acquisition module 11 are included in the real-time measurement parameters acquired by the top drive control system 19.

That is, the real-time measurement parameters acquired by the data acquisition module 11 have a corresponding relationship with the opened functions of the top drive control system 19. For example, when the function opened by the top drive control system 19 is the torque upper limit set value, the real-time measurement parameters acquired by the data acquisition module 11 need to include the torquemeter indication on the top drive drilling system. When the function opened by the top drive control system 19 is the upper speed limit set value, the real-time measurement parameters acquired by the data acquisition module 11 need to include the speedometer indication on the top drive drilling system.
Further, the output end of the data acquisition module 11 is connected with the communication module 15. So that the data acquisition module 11 can send the real-time measurement parameters to the communication module 15.
In this embodiment, the communication module 15 is configured to receive real-time measurement parameters and parameters intrinsic to the top drive drilling system. The intrinsic parameter may be information related to the top drive drilling system. For example, the intrinsic parameter may be a start delay time of the top drive, an acceleration characteristic of the top drive, or the like. The communication module 15 is used for receiving the real-time measurement parameters acquired by the data acquisition module 11. The real-time measurement parameters can be stored in the memory 23, so that the communication module 15 can record the parameters of the top drive drilling system, and can output the parameters in a report form when necessary, so that the parameters can be referred and analyzed by a user on one hand, and data support is provided for better understanding of the top drive drilling system on the other hand.
further, the communication module 15 can be connected to the top drive drilling control optimization device 21 so that the top drive drilling control optimization device 21 can obtain real-time measurement parameters and intrinsic parameters. Therefore, the top drive drilling control optimization device 21 can automatically read the inherent parameters of the top drive drilling system and automatically adjust the internal control logic according to the inherent parameters, so that the control logic is prevented from being manually modified according to the characteristics of the top drive drilling system, and the working efficiency of the top drive drilling control optimization device 21 can be improved.

That is, the function of the top drive control system 19 being opened is taken over by the top drive drilling control optimization device 21, thereby enabling optimal control of the top drive drilling system.
In this embodiment, the input of the data transmission module 13 is used for connecting with the top drive control system 19. The input end of the data transmission module 13 is connected with the top drive control system 19. That is, the data transmission module 13 is not directly connected to the top drive drilling system, but is directly connected to the top drive control system 19. So that the top drive drilling system can be controlled by the top drive control system 19.
Further, the data sending module 13 is configured to send a control signal to the top drive control system 19 according to the control instruction. The data transmission module 13 needs to transmit the control signal according to the top drive drilling system. The control signal can be 4-20 mA current. Or a voltage of 0 to 10V.

Thus, when the top drive drilling control optimization device 21 is not needed, the relay releases all control authority of the top drive drilling system to the top drive control system 19 in the first working position. I.e. all functions of the top drive drilling system are controlled entirely by the top drive control system 19.
That is, because of the existence of the relay, the top drive drilling control auxiliary device of the embodiment of the present application can ensure that all functions and operations of the top drive drilling system are kept unchanged no matter whether the top drive drilling control optimization device 21 is connected or not after being connected with the top drive drilling system.
