Description

Technical Field

[0001] The invention belongs to the technical field of oil rig safety management, relates to an oil rig space safety analysis system, and also relates to the oil rig space safety analysis method. Background Art

[0002] With the improvement of the automation level of oil drilling rigs and the introduction of a large number of equipment, the collision of cross-operation areas during drilling rig operations has gradually become one of the major accidents. At this time, how to predict potential safety risks by analyzing the distance between personnel and equipment, and between equipment, and to nip accidents in the bud is becoming increasingly important.

[0003] There are two main traditional means of preventing collisions: the first is to set up rules and regulations for on-site manual management, but the effect of manual management is directly related to personal experience. This management model varies from person to person and cannot be replicated in a large-scale standardized manner. The second is to introduce various sensors or signal sensing devices to achieve management. This also has great limitations. The former can only detect a specific two-dimensional space (such as height detection); the latter (such as posting induction signs) has requirements for the layout of the signal receiving device. At the same time, if multiple areas are to be detected or there is an obstructed environment, multiple groups of equipment must be arranged. Considering safety redundancy and failures, the same position must be arranged in groups, so this method is costly and limited in use.

[0004] At present, there is no safety analysis system in China that can perform spatial position analysis on specific objects (personnel or equipment) within the three-dimensional space of an oil rig, predict potential safety risks and output warning signals based on the spatial distance between the specific objects and other objects. Summary of the invention

[0005] The purpose of the present invention is to provide an oil rig spatial safety analysis system, which solves the problem that the prior art is unable to perform spatial position analysis on specific objects within the three-dimensional spatial area of ​​the oil rig, and at the same time predict potential safety risks and output warning signals based on the spatial distance between the specific object and other objects.

[0006] Another object of the present invention is to provide a method for analyzing the spatial safety of an oil rig, measure the spatial distance between specific objects, provide early warning for potential collision avoidance of specific objects, and reduce the risk of accidents.

[0007] The technical solution adopted by the present invention is that the oil rig space safety analysis system includes a processing unit, the input end of the processing unit is respectively connected to an image recognition unit, a storage unit, and an operation and display unit; the output end of the processing unit is respectively connected to an alarm unit and a third-party device.

[0008] The present invention is also characterized in that:

[0009] The operation and display unit, storage unit, alarm unit, processing unit and third-party equipment are all installed indoors or in a place with a certain degree of protection; the image recognition unit is installed near the space area that needs to be detected.

[0010] The operation and display unit is also connected to an industrial computer.

[0011] The image recognition unit is used to capture the spatial three-dimensional image information of the object under test; the processing unit is used to process the collected data, accurately distinguish the object under test in three-dimensional space and determine the spatial coordinates, obtain the spatial distance between the object under test and other objects, and at the same time set threshold analysis and output control commands based on the operation and display unit.

[0012] Another technical solution adopted by the present invention is a method for analyzing the spatial safety of an oil drilling rig, which is specifically as follows: Step 1, inputting a feature model of the object to be analyzed into a processing unit, and setting a corresponding distance threshold parameter in an operation and display unit, and then setting an image recognition unit near the three-dimensional area to be analyzed to identify the three-dimensional coordinate information of the object to be measured in the three-dimensional area, and checking the content of the storage unit if content playback is required; Step 2, when an object with obvious features of the object to be measured enters the monitoring range, the image recognition unit sends the recognized three-dimensional image signal to the processing unit, and the processing unit processes the collected data, collects spatial information, models the spatial relationship, and creates a physical world mapping expression; at the same time, data comparison is performed according to the set distance threshold in the operation and display unit, and an early warning and action command are output in a timely or delayed manner according to the comparison result; if the actual distance value meets the trigger condition, the alarm unit is activated and a signal is sent to a third-party device at the same time; if the actual distance value is greater than the threshold, a cancellation of the early warning and action command is output in a timely or delayed manner.

[0013] Another technical solution of the present invention is characterized in that:

[0014] Step 2: Control is implemented according to the following three conditions:

[0015] Condition 1) When an object with obvious equipment and equipment features enters the monitoring range, the image recognition unit sends the recognized three-dimensional image signal to the processing unit, which processes the collected data, collects its spatial information, models its spatial relationship, and creates a physical world mapping expression; at the same time, it performs data comparison based on the set distance threshold in the operation and display unit, and outputs warnings and action commands in a timely or delayed manner based on the comparison results; if the actual distance value meets the triggering conditions, the alarm unit is activated and a signal is sent to the third-party device at the same time; if the actual distance value is greater than the threshold, the warning and action command are canceled in a timely or delayed manner;

[0016] Condition 2) When an object with obvious human and equipment characteristics enters the monitoring range, the image recognition unit sends the recognized three-dimensional image signal to the processing unit, which processes the collected data, collects its spatial information, models its spatial relationship, and creates a physical world mapping expression; at the same time, the data is compared according to the set distance threshold in the operation and display unit, and according to the comparison result, the warning and action command are output in time or with delay; if the actual distance value meets the trigger condition, the alarm unit is activated and a signal is sent to the third-party device at the same time; if the actual distance value is greater than the threshold, the warning and action command are canceled in time or with delay;

[0017] Condition 3) When an object with obvious human features enters the monitoring range, the image recognition unit sends the recognized three-dimensional image signal to the processing unit, which processes the collected data, collects its spatial information, models its spatial relationship, and creates a physical world mapping expression; at the same time, it performs data comparison based on the set distance threshold in the operation and display unit, and outputs warnings and action commands in a timely or delayed manner based on the comparison results; if the actual distance value meets the triggering conditions, the alarm unit is activated and a signal is sent to a third-party device at the same time; if the actual distance value is greater than the threshold, the warning and action command are canceled in a timely or delayed manner.

[0018] The beneficial effects of the present invention are:

[0019] The oil rig space safety analysis method of the present invention can realize dynamic analysis of the three-dimensional space safety of a certain area without human intervention. When the distance between specific objects is less than the set value, an early warning is issued and measures are automatically taken. At the same time, it has strong adaptability to different background environments.

[0027] The processing unit 2 is the control core, which completes the image information collection, logic judgment, and transmission of the image recognition unit 1; the operation and display unit 6 is an industrial computer with a human-computer interaction interface, and runs a high-level programming language inside.

[0028] The oil rig space safety analysis system of the present invention has the following specific features:

[0029] 1) According to the characteristics of the working conditions, an artificial intelligence algorithm is introduced into the processing unit 2 to process the collected data, accurately distinguish the target in three-dimensional space, determine the spatial coordinates of the target, and obtain three-dimensional data; at the same time, based on the algorithm and the set value analysis of the operation and display unit 6, the signal is judged and the control command is output.

[0030] 2) The operation and display unit 6 is also connected to an industrial computer for displaying and setting data.

[0032] 4) The operation and display unit 6 can set the distance threshold and detection object by itself, and can set multiple detection objects at the same time, and use different distance thresholds for different detection objects to issue alarm prompts. Figure 3 .

[0033] 5) The spatial three-dimensional image information of the measured object is captured by the image recognition unit 1 and then sent to the processing unit 2: The spatial three-dimensional image information of the measured object includes X-axis, Y-axis and Z-axis information. The processing unit 2 captures the distance values ​​between specific objects in real time, such as Figure 3 If the distance value reaches the threshold value set by the operation and display unit 6, the signal output end of the processing unit 2 is connected to the alarm unit 3 and the third-party device 5 to achieve synchronous transmission of the alarm and the signal.

[0035] Preparatory steps: First, input the feature model of the specific object to be analyzed into the processing unit 2, and set the corresponding distance threshold parameter in the operation and display unit 6, and then set the image recognition unit 1 near the three-dimensional area to be analyzed to identify the three-dimensional coordinate information of the specific object in the area. If content playback is required, check the contents of the storage unit 4.

[0036] Situation 1) When an object with obvious equipment and equipment features enters the monitoring range, the image recognition unit 1 sends the recognized three-dimensional image signal to the processing unit 2.

At the same time, the data is compared according to the set distance threshold in the operation and display unit 6, and the warning and action command are output in time or with delay according to the algorithm result. If the actual distance value (such as Figure 3 If the medium distance 1) meets the triggering conditions, the alarm unit 3 is activated and a signal is sent to the third-party device 5; if the actual distance value is greater than the threshold, the warning and action command are canceled in time or with delay.

The processing unit 2 processes the collected data through the algorithm, collects its spatial information, models its spatial relationship, and creates a physical world mapping expression. At the same time, the data is compared according to the set distance threshold in the operation and display unit 6, and the warning and action command are output in time or with delay according to the algorithm result.

[0038] Condition 3) When an object with obvious human features enters the monitoring range, the image recognition unit 1 sends the recognized three-dimensional image signal to the processing unit 2. The processing unit 2 processes the collected data through the algorithm, collects its spatial information, models its spatial relationship, and creates a physical world mapping expression. At the same time, the data is compared according to the set distance threshold in the operation and display unit 6, and the warning and action command are output in time or with delay according to the algorithm result. If the actual distance value ( Figure 3 If the medium distance 6) meets the triggering conditions, the alarm unit 3 is activated and a signal is sent to the third-party device 5; if the actual distance value is greater than the threshold, the warning and action command are canceled in time or with delay.
