Abstract

A comprehensive monitoring system and method for preventing collisions with the traveling hook height via digital display includes a lifting ring attitude detection unit, a central processing unit, a winch shaft head sensing unit, a vision detection unit, and a data monitoring center. The lifting ring attitude detection unit, winch shaft head sensing unit, and vision detection unit are all connected to the central processing unit, which in turn is connected to the data monitoring center. This invention acquires the traveling hook's running position and winch shaft head torque via an encoder installed on the winch shaft head.

Description

Technical Field

[0001] This invention belongs to the field of anti-collision monitoring technology, and specifically relates to a digital display anti-collision integrated monitoring system and method for large hook height. Background Technology

[0002] Drilling rigs are crucial equipment in the oil drilling industry, and the position of the hook on each rig needs real-time monitoring to prevent accidents such as overshooting and impacts to the drilling platform caused by human error. While electronic anti-collision devices are widely used in oil drilling, current devices are too limited in function. As safety devices for drilling rigs, they cannot provide comprehensive sensing and alarms for the complex operating conditions of the rig. They only monitor the tilt angle of the lifting ring, lacking comprehensive monitoring of the lifting ring's posture and the ability to sense and identify the position of operators on the drilling platform, thus failing to provide all-round monitoring of potential safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide a comprehensive monitoring system and method for anti-collision with digital display of hook height, in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A large hook height digital display anti-collision integrated monitoring system includes a lifting ring attitude detection unit, a central processing unit, a winch shaft head sensing unit, a vision detection unit, and a data monitoring center; the lifting ring attitude detection unit, the winch shaft head sensing unit, and the vision detection unit are all connected to the central processing unit, and the central processing unit is connected to the data monitoring center;

[0006] The ring attitude detection unit is used to collect the attitude data of the ring and transmit it to the central processing unit wirelessly.

[0007] The winch shaft head sensing unit is used to acquire the running position of the traveling block hook and the torque of the winch shaft head, and send them to the central processing unit.

[0008] The visual inspection unit is used to collect information about personnel on the drilling platform and send it to the central processing unit;

[0009] The central processing unit comprehensively compares the above data and information to correct the position of the travel trolley hook.

[0010] Furthermore, the ring attitude detection unit consists of two attitude detection sensors, an attitude data preprocessing unit, and a wireless transmission module. The two attitude detection sensors are respectively installed on two rings and are simultaneously connected to the attitude data preprocessing unit. The attitude data preprocessing unit is connected to the central processing unit through the wireless transmission module.

[0011] Furthermore, a motion power generation module is also installed on the ring, which is connected to a kinetic energy harvesting module, which in turn is connected to an attitude detection sensor and an attitude data preprocessing unit.

[0012] Furthermore, the visual inspection unit includes a human detection camera and a visual data preprocessing unit. The human detection camera is connected to the visual data preprocessing unit, and the visual data preprocessing unit is connected to the central processing unit.

[0013] Furthermore, the winch shaft head sensing unit is an encoder installed on the winch shaft head, used to convert the winch rotation signal into the up and down position signals of the traveling hook.

[0014] Furthermore, the data monitoring center serves as a storage server, used to store data sent from the central processing unit.

[0015] Furthermore, the central processing unit is connected to an audible and visual alarm.

[0016] Furthermore, a monitoring method for a large hook height digital display anti-collision integrated monitoring system includes the following steps:

[0017] The encoder installed on the winch shaft head converts the winch rotation signal into the up and down position signals of the traveling hook. The acceleration signals of the two lifting ring attitude sensors are compared to obtain the acceleration difference. The acceleration difference is used to correct the running acceleration of the hook and further correct the hook position.

[0018] The encoder installed on the winch shaft head converts the winch rotation signal into the up and down position signals of the traveling hook. When the traveling hook reaches the up or down warning position, the central processing unit reminds the driller in the form of an audible and visual alarm. When the traveling hook reaches the up or down brake position, the control control unit outputs a brake signal to force braking.

[0019] When the hoisting ring attitude sensor installed on the hoisting ring detects that the hoisting ring tilt angle exceeds the predetermined value θ1, and the traveling trolley hook has reached the upper and lower limits of the second-floor platform, the central processing unit issues a braking signal.

[0020] When the traveling block hook reaches the active braking position, the vision sensor detects personnel activity at the wellhead, and then the active braking is activated.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] This invention acquires the traveling hook's running position and the winch shaft torque via an encoder installed on the winch shaft head. This data is then integrated with data from the lifting ring attitude sensor and a vision sensor to prevent the traveling hook from colliding with or impacting the platform, and to trigger an alarm for any winch malfunctions. The invention also fuses and compares the data with the lifting ring attitude data to correct the traveling hook's position. The fusion of the lifting ring's tilt angle data and the traveling hook's position data effectively prevents the lifting ring from colliding with the second-level platform. The combination of the vision sensor data and the hook's position data effectively prevents safety hazards caused by personnel movement on the drilling platform during the hook's descent.

[0023] The ring attitude sensor used in this invention can collect not only the ring tilt angle data, but also the gravitational acceleration and horizontal height data during the fall, thus obtaining more attitude information. The power supply method for the ring attitude detection unit in this invention adopts a "motion power generation module" and a "kinetic energy harvesting module" to collect and store the energy generated by the ring's up and down movement and supply it to the attitude detection module, reducing the need for additional power supply and enabling the equipment to operate stably for a long time.

[0024] This invention uses a visual sensing unit installed in the driller's cabin to monitor the operation of the hook and the activities of personnel in a specific area of ​​the drilling platform in real time. When there is a safety hazard, it can automatically brake to avoid safety accidents.

[0025] This invention uses independent detection units installed in different locations to perform data fusion, enabling mutual correction and supplementation of key drilling data such as the operating position of the traveling block hook. This allows for a true and accurate reflection of the operating status of the drilling rig hook and provides an alarm for cases with excessive data deviation, facilitating timely human intervention and maintenance.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] Please see Figures 1 to 7 A comprehensive monitoring system and method for anti-collision with digital display of hook height includes:

[0035] 1. The tilt angle, running speed, acceleration and other information of the lifting ring are sensed by the attitude sensor installed on the lifting ring, and the information is transmitted to the central processing unit wirelessly.

[0036] 2. The activities of personnel on the drilling platform are detected by visual sensors installed in the driller's cabin.

[0037] 3. The traveling hook's running position and the winch shaft torque are acquired by an encoder installed on the winch shaft head. This data is then integrated with data from the lifting ring attitude sensor and the vision sensor to prevent the traveling hook from colliding with or impacting the winch, and to trigger an alarm for any winch malfunctions. The traveling hook position data is also fused and compared with the lifting ring attitude data to correct the overall position. The fusion of the lifting ring's tilt angle data and the traveling hook position data effectively prevents the lifting ring from colliding with the second-level platform. The combination of the vision sensor data and the hook position data effectively prevents safety hazards caused by personnel movement on the drilling platform during the hook's descent.

[0038] 3.1 The encoder installed on the winch shaft head converts the winch rotation signal into the up and down position signals of the traveling hook. When the traveling hook reaches the up or down warning position, the central processing unit alerts the driller with an audible and visual alarm. When the traveling hook reaches the up or down brake position, the control unit outputs a brake signal to force braking to prevent the traveling hook from hitting the top of the drill table or impacting the drill table.

[0039] 3.2 When the hoisting ring attitude sensor installed on the hoisting ring detects that the hoisting ring tilt angle exceeds the predetermined value θ1 and the traveling trolley hook has reached the upper and lower limits of the second-floor platform, the central processing unit issues a braking signal to prevent the traveling trolley hook from impacting the second-floor platform due to the hoisting ring tilt when approaching it.

[0040] 3.3 The position of the end point of the lifting ring can be obtained. The position of the second platform on the drilling rig is fixed. Therefore, θ1 can be calculated from the collision point between the end of the lifting ring and the second platform. This is the predetermined value of the lifting ring tilt angle limit.

[0041] 3.4 When the traveling block hook reaches the active braking position, the vision sensor detects personnel activity at the wellhead and applies the active braking to prevent the traveling block hook from continuing to fall and causing injury to the personnel at the wellhead.

[0042] 4. The non-volatile storage unit within the central processing unit can record operational data such as the position of the traveling crane hook and the posture of the lifting ring in real time, and has a power-off retention function, facilitating the review and tracking of on-site work conditions. The 5G module within the central processing unit uploads the processed real-time operational data to the monitoring center, enabling centralized and unified management of on-site work.

[0043] The hoop attitude sensor used can collect not only the hoop tilt angle data, but also the gravity acceleration and horizontal height data during the fall, to obtain more attitude information. In this invention, the power supply method for the hoop attitude detection unit adopts a "motion power generation module" and a "kinetic energy harvesting module" to collect and store the energy generated by the hoop's up and down movement and supply it to the attitude detection module.

[0044] Each lifting ring is equipped with an independent detection unit, which enables redundant detection; in addition, an alarm can be issued when the data from two detection units deviate too much, thus preventing drilling from starting with a single lifting ring.

[0045] The operation of the hook and personnel activities in a specific area of ​​the drilling platform are monitored in real time by a visual sensing unit installed in the driller's cabin. When there is a safety hazard, the system can automatically brake to avoid accidents.

[0046] By using independent detection units installed in different locations and through data fusion, key drilling data such as the operating position of the traveling block hook can be mutually corrected and supplemented. This allows for a true and accurate reflection of the operating status of the drilling rig hook and provides an alarm for cases with excessive data deviation, enabling timely human intervention and maintenance.

[0047] The central data processing unit has a 5G data upload interface, which can upload the drilling rig's local data to the monitoring center via the 5G network.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
