[0037] See also Figure 1 The utility model provides a control system for a mud pump 3, including a mud pump 3, a data processing module 1 and at least one control module 2; the control module 2 includes a signal-connected emergency stop unit 21, a standpipe pressure acquisition unit 22 and a LORA unit 23, the emergency stop unit 21 is electrically connected to the mud pump 3 to control the start and stop of the mud pump 3; the data processing module 1 includes a processor 11, an alarm module 12 and a signal transmission module 13, the processor 11 is signal-connected to the alarm module 12 and the signal transmission module 13 respectively, and the signal transmission module 13 is signal-connected to the LORA unit 23.

[0038] It should be noted that the control module 2 is arranged on the mud pump 3, and is used to detect the standpipe pressure when the mud pump 3 is working, and transmits the detected standpipe pressure signal to the processor 11 through the LORA unit 23 and the signal transmission module 13. The processor 11 determines whether it is within the safety threshold range based on the current standpipe pressure. If the current standpipe pressure exceeds the safety threshold, the processor 11 transmits a signal to the emergency stop unit 21 through the signal transmission module 13 and the LORA unit 23, and the emergency stop unit 21 controls the mud pump 3 to shut down, thereby realizing automatic monitoring of the mud pump 3 and avoiding safety accidents caused by sudden changes in pump pressure during the operation of the mud pump 3.

[0039] It should be noted that, in the present embodiment, a plurality of control modules 2 may be included, each control module 2 being respectively arranged on a mud pump 3, and the data processing module 1 may be arranged in a special control room, so that the operation of the plurality of mud pumps 3 may be monitored through the data processing module 1, thereby reducing the energy of the operator, and when the riser pump pressure of the mud pump 3 is abnormal, the mud pump 3 may be shut down in time.

[0040] It should be noted that, in the present embodiment, the processor 11 may specifically include a plurality of comparison modules, and different comparison modules correspond to different mud pumps 3. It can be understood that different comparison modules may be provided with different thresholds, so as to realize the monitoring of mud pumps 3 of different models. When the riser pressure of one of the mud pumps 3 exceeds the safety threshold, the data processing module 1 sends a signal to the corresponding LORA unit 23 through the signal transmission module 13. After receiving the signal, the LORA unit 23 transmits it to the emergency stop unit 21, thereby controlling the shutdown of the corresponding mud pump 3.

[0041] It should be noted that the alarm module 12 may specifically include one or more of a vibration alarm unit, a sound alarm unit and a light alarm unit, and alarms when the riser pressure of the mud pump 3 exceeds a safety threshold, thereby reminding the operator to handle the problem.

When the standpipe pressure of the mud pump 3 exceeds the safety threshold of the first comparison module, such as 16 MPa, the first comparison module sends a first alarm signal to the alarm module 12, and the alarm module 12 activates a first-level alarm, such as emitting a green light through the optical alarm unit; When the standpipe pressure of the mud pump 3 exceeds the safety threshold of the second comparison module, such as 25 MPa, the second comparison module sends a second alarm signal to the alarm module 12, and the alarm module 12 sends an alarm, such as emitting yellow light through the optical alarm unit; when the standpipe pressure of the mud pump 3 exceeds the safety threshold of the third comparison module, such as 31 MPa, the third comparison module sends a signal to the corresponding emergency stop unit 21 through the signal transmission module 13 and the LORA unit 23 to control the corresponding mud pump 3 to shut down, and sends a third alarm signal to the alarm module 12, and the alarm module 12 sends an alarm, such as emitting red light through the optical alarm unit, or alarming through the sound alarm module 12. The hierarchical alarm setting can be based on different mud pumps 3, and this embodiment does not make specific limitations.

[0043] In some embodiments, the data processing module 1 can be arranged in a visual explosion-proof box, which can, on the one hand, prevent dust and water as well as external damage, and on the other hand, can also perform visual monitoring.

[0044] It should be noted that the signal transmission module 13 in the data processing module 1 in this embodiment specifically includes a LORA transceiver unit, which is used to connect the signal of the LORA unit 23 in the control module 2 to achieve local wireless communication. Specifically, the LORA unit 23 amplifies the received signal through a low noise amplifier (LNA) while minimizing the noise in the signal, thereby improving the signal-to-noise ratio of the signal, and through array technology, it can simultaneously receive signals from multiple directions, which is used in this embodiment to achieve multi-path reception and thus monitor multiple mud pumps 3.

[0046] Furthermore, the data processing module 1 also includes a display module 15 , and the display module 15 is signal-connected to the processor 11 and the storage module 14 .

[0047] It should be noted that the storage module 14 is used to store the signal transmitted by the control module 2 in real time, so that the user can retrieve the working status of the mud pump 3 at a later time.

[0048] It should be noted that the display module 15 is specifically a display, which can display the current working status of the mud pump 3 in real time, and the user can retrieve historical monitoring data to facilitate the analysis of historical data.

[0049] In some embodiments, the display module 15 may specifically be a hydraulic display, which is convenient for users to set different safety threshold data. The mud pump 3 may also be started and stopped manually through the display module 15, which will not be elaborated in this embodiment.

[0051] It should be noted that the step-down unit 161 is mainly responsible for stepping down the external AC high voltage electricity and converting it into the DC low voltage electricity required by the processor 11, so that the data processing module 1 of this embodiment can be applied to different environments.

[0052] In some embodiments, the protection module 16 also includes an EMC module, which enables the data processing module 1 to work normally in an electromagnetic environment without interfering with other surrounding devices and systems. Specifically, before use, an EMC conducted interference test can be performed to prevent interference signals generated by electronic devices from interfering with each other through conductive media or common power lines; and safety capacitors can be added to the circuit to process interference signals generated by external devices and transmit the interference signals to the electronic device through spatial coupling. This prevents electromagnetic interference generated by some external electronic products from affecting or destroying the normal operation of the electronic device.

[0053] In some embodiments, the protection module 16 also includes an energy storage unit, which can realize the conversion between electrical energy and chemical energy to solve the problem of sudden power outage or an environment in which the power supply network is not yet perfect, so that the data processing module 1 provided in this embodiment can still be used normally.

[0056] It should be noted that, compared with LORA signal transmission, the LTE4G module supports high-speed data transmission and has a higher transmission rate, which facilitates the transmission of the usage of the mud pump 3 to the terminal 4 for storage.

[0057] For further information, see Figure 1 and Figure 4 The control module 2 also includes a speed acquisition module 24 , and the speed acquisition module 24 is signal-connected to the LORA unit 23 .

[0058] It should be noted that the speed collection module 24 is used to collect the speed data of the mud pump 3 , so as to facilitate the user to grasp more specific data about the operation of the mud pump 3 .

[0059] Furthermore, the control module 2 also includes a lighting unit 25 and a sensing sensor 26 connected to the lighting unit 25 by a signal, and the sensing sensor 26 includes any one of a microwave sensor, an AI camera recognition sensor and an infrared sensor.

[0060] It should be noted that the induction sensor 26 is used to detect when a person or object is close to the mud pump 3, and illuminates through the lighting unit, which is convenient for users to perform construction operations in an environment with insufficient light, and also plays a role in energy saving.

[0061] It should be noted that microwave sensors are used to detect the presence and movement of moving objects within the sensing range by sending microwave signals and detecting their reflections; infrared sensors can detect the movement of human bodies or objects; AI camera recognition sensors mainly analyze images or video data captured by cameras using artificial intelligence algorithms to achieve object recognition, face recognition, motion analysis, etc. In this implementation, one type can be set separately or in combination to reduce sensing errors. The settings are based on different usage environments, and this embodiment will not be described in detail.
