Description

Technical Field

[0001] The present invention relates to the technical field of oil well leakage detection, in particular to an oil well leakage detection system based on visual recognition technology. Background Art

[0002] At present, in the oil collection industry, the oil pumps are not only extremely scattered, but also located in remote areas, which brings a lot of inconvenience to the monitoring of the working status of the oil pumps. One of the monitoring of the working status of the oil pumps is to detect whether there is an oil leakage. During the oil production process, due to repeated friction between the light rod and the oil production tree pipeline joint, the wear of the light rod often causes excessive gaps and oil leakage. The existing method of manually checking the site regularly to check the oil leakage problem generally has the problems of high labor intensity and untimely detection. Some security cameras are also used in combination with image recognition methods for oil leakage detection. However, since the traces of oil leakage are very similar to sunlight shadows, puddles, etc. at the scene, it is very easy to cause misjudgment or missed judgment. It has been found that crude oil contains unsaturated hydrocarbons and their derivatives, which have fluorescence. When irradiated with ultraviolet light of a specific wavelength, fluorescence of a specific wavelength will be generated. At present, the fluorescence of crude oil is mainly used to detect the properties of crude oil in different target layers. Therefore, based on the above problems and the prior art, the present application designs an oil well oil leakage detection system based on visual recognition technology to improve the success rate and accuracy of oil leakage detection. Summary of the invention

The image collector can obtain image information of a collection area 6 and send it to the image processor for processing. The filter component comprises a filter lens 11, a rotating shaft 12 and a driving unit 13. The filter lens 11 is fixed on the rotating shaft 12 and can be blocked at the image collector. The driving unit 13 can drive the rotating shaft 12 to rotate and then drive the filter lens 11 to rotate so that the image collector can determine whether it is in the collection area. 6 obtains light and shadow of a specific wavelength; the ultraviolet generating device 2 includes an ultraviolet emitting module 21, which is used to emit ultraviolet rays to the irradiation area 5, and the ultraviolet rays will generate stimulated fluorescence when irradiated on the crude oil; the control unit 3 includes a controller and a wireless signal transceiver module, and the controller is electrically connected to the image acquisition device 1 and the ultraviolet generating device 2, wherein the controller controls the driving unit 13 to start, or the controller controls the driving unit 13 and the ultraviolet emitting module 21 to start synchronously, and the wireless signal transceiver module is used to send the image information processed by the image processor to the host computer, and to transmit the charge instruction issued by the host computer to the controller.

[0005] As a preferred embodiment of the present application, the range of the irradiation area 5 is less than or equal to the range of the collection area 6.

When the ultraviolet intensity in the current environment meets the requirements, there is no need to start the ultraviolet emitting module 21 when acquiring the filtered image after ultraviolet irradiation.

[0007] As a preferred embodiment of the present application, the ultraviolet generating device 2 further includes a living organism detection module 26 and / or an alarm module 27. The living organism detection module 26 is used to detect whether a person or animal has entered the irradiation area 5 before starting the ultraviolet emission module 21. The alarm module 27 is used to make a remote or on-site alarm to warn people or animals to stay away from the irradiation area 5, or to remind nearby staff to deal with the oil leakage in time.

DETAILED DESCRIPTION

[0023] Embodiment 1:

[0024] The present embodiment provides an oil well leakage detection system based on visual recognition technology. The system is arranged on one side of the oil pumping unit when in use, and is used to detect whether the oil pumping unit is leaking oil. Specifically, the system comprises an image acquisition device 1, an ultraviolet generating device 2 and a control unit 3. In the present embodiment, the image acquisition device 1, the ultraviolet generating device 2 and the control unit 3 are arranged on the same support frame 4 (hereinafter referred to as an integrated arrangement). Figure 1 , wherein the specific setting position or height of the image acquisition device 1 and the ultraviolet generating device 2 is selected according to the actual situation, and this embodiment does not make specific restrictions. The use of this integrated setting structure is not only convenient for installation, but also convenient for maintenance and management. However, the integrated installation structure may have the problem of unclear or unclear fluorescent points in the acquired image due to light reflection in actual use. In order to solve this problem, this embodiment preferably fixes the image acquisition device 1 and the ultraviolet generating device 2 on independent support frames 4 respectively (the control unit 3 is preferably but not limited to being arranged on the support frame 4 of the image acquisition device 1), see Figure 2 During installation, the image acquisition device 1 and the ultraviolet generating device 2 are fixed at two relative positions respectively, so that the reflected light of the stimulated fluorescence generated by the ultraviolet rays shining on the crude oil can be collected more by the image acquisition device 1, which will improve the collection precision and accuracy of the image acquisition device 1. At the same time, the advantage of setting the image acquisition device 1 and the ultraviolet generating device 2 as independent structures is that: when the collection area 6 of the image acquisition device 1 (the maximum collection range of the image acquisition device) is large, it can be achieved by one group of image acquisition devices 1 corresponding to multiple groups of ultraviolet generating devices 2, that is, the collection area 6 of one group of image acquisition devices 1 is irradiated by multiple groups of ultraviolet generating devices 2, or, when the irradiation area 5 of the ultraviolet generating device 2 (the maximum irradiation range of the ultraviolet generating device 2) is large or variable, one group of ultraviolet generating devices 2 can correspond to multiple groups of image acquisition devices 1, that is, the collection areas 6 of multiple image acquisition devices 1 are irradiated by one group of ultraviolet generating devices 2, which will reduce the system use cost to a certain extent.

[0025] The image acquisition device 1 includes an image acquisition device, an image processor and a filter component. The image acquisition device and the image processor are preferably fixed in a collection cover 10 with an opening on one side. The filter component is fixed at the opening of the collection cover 10. In this embodiment, the image acquisition device is a charge coupled device (CCD), which can obtain image information (analog electrical signals) in the collection area 6 and send the collected analog electrical signals to the image processor. In this embodiment, the image processor is an existing digital signal processing chip (DSP). The DSP performs a series of operations (color, brightness, white balance, etc.) such as analog-to-digital conversion and processing on the received analog electrical signals to output an image (video or picture). The filter component includes a filter lens 11, a rotating shaft 12 and a driving unit 13. The filter lens 11 is fixed on the rotating shaft 12 and can be blocked at the probe of the image acquisition device, see Figure 3-6The filter lens 11 can be used to enable the image collector to collect light and shadow within a specific wavelength range. The driving unit 13 can drive the rotating shaft 12 to rotate and then drive the filter lens 11 to rotate so that the image collector can obtain light and shadow of a specific wavelength in the collection area 6. That is, when the filter lens 11 rotates with the rotating shaft 12 and blocks the image collector probe, the light and shadow obtained by the image collector at this time does not include the light and shadow within the wavelength filtered out by the filter lens 11. When the filter lens rotates with the rotating shaft 12 and does not block the image collector probe, the image collector collects light within the visible light range. In this embodiment, the filter lens 11 can obtain light in the UVA band, that is, light waves with a wavelength between 320nm-380nm, that is, when the filter lens 11 blocks the image collector probe, the image collector can only obtain light and shadow with a wavelength between 320nm-380nm. In this embodiment, the driving unit 13 includes a stepper motor and a stepper motor driving module; the ultraviolet generating device 2 includes an ultraviolet emitting module 21. In this embodiment, the ultraviolet emitting module 21 is preferably fixed in an ultraviolet cover with an opening on one side, see Figure 7The ultraviolet emitting module 21 is used to emit ultraviolet rays to the irradiation area 5 in the collection area 6. Due to the fluorescence of crude oil, the ultraviolet rays will generate stimulated fluorescence when irradiated on the crude oil. In this embodiment, it is known through experiments that the wavelength of the stimulated fluorescence is between 300nm and 380nm. In this embodiment, the ultraviolet emitting module 21 includes an ultraviolet lamp and an ultraviolet lamp driving module, wherein the radiation intensity of the ultraviolet lamp can be adjusted by the ultraviolet lamp driving module; the control unit 3 includes a controller and a wireless signal transceiver module, and the control unit 3 is electrically connected to the image collection device 1 and the ultraviolet generating device 2. Specifically, the stepper motor driving module and the ultraviolet lamp driving module are respectively connected to the I / O port of the controller. When in use, the controller only sends enabling information to the stepper motor driving module through the I / O port (at this time, the ultraviolet intensity in the external environment meets the current demand), or the control The controller sends the enabling information to the stepper motor driving module and the ultraviolet emission module 21 through the I / O port at the same time. The stepper motor driving module receives the enabling signal from the controller, and then processes the enabling signal to start the stepper motor, and feeds back the working condition of the stepper motor to the controller. The ultraviolet emission module 21 receives the enabling signal from the controller, and then processes the enabling signal to start the ultraviolet lamp, and feeds back the working condition of the ultraviolet lamp to the controller. The wireless signal transceiver module is used to send the image information processed by the image processor to the host computer, and to transmit the accusation command issued by the host computer to the controller. In this embodiment, the wireless signal transceiver module is preferably an industrial-grade wireless programming communication module of Haitongda, whose model is HTD-WR8003. The wireless communication module supports the standard MODBUS protocol, including MODBUS ASCII protocol and MODBUS RTU protocol, and has the characteristics of long-distance communication, high stability, low failure rate and low cost. It provides a wealth of peripheral interfaces (RS232\RS485\PPI\Ethernet), and the collected data can be transmitted in real time, meeting customers' requirements for data real-time and accuracy, greatly reducing labor intensity and enterprise operating costs; in this embodiment, the host computer includes a video, image display unit and a human-computer interaction interface, etc. The host computer can be a remote industrial computer or a mobile terminal such as a computer or a mobile phone.

[0026] In this embodiment, in order to save costs, the image collector and the image processor may use existing security cameras installed around the oil well.

[0027] In this embodiment, the range of the irradiation area 5 is smaller than or equal to the range of the collection area 6 .

[0028] When in use, under normal circumstances, the image collector, the image processor and the control unit 3 are used as general security cameras, which collect images around the oil pump and transmit them to the host computer. When the specified time or preset time arrives (preset in advance or manually send instructions on site), the control unit 3 starts the filter component and the ultraviolet emission module 21. At this time, the image collector will obtain the light and shadow information after filtering and irradiation with ultraviolet rays, that is, obtain the light and shadow information with a wavelength between 300nm-380nm, and convert the light and shadow information into an electrical signal and transmit it to the image processor. The image processor outputs an image after processing the received electrical signal and transmits the image to the control unit 3. The control unit 3 then transmits the image to the remote host computer. If there are fluorescent spots in the output image, it means that there is a crude oil leakage phenomenon. In this embodiment, in order to improve the detection precision and accuracy of the detection system, the image acquisition device 1 of this embodiment can preferably obtain images of multiple time periods, and the control unit 3 or the host computer can compare the images of the multiple time periods. If the fluorescent spots in the images of multiple time periods increase with the time period, it means that there must be an oil leakage phenomenon.

[0029] In summary, the detection system in this embodiment can improve the accuracy and timeliness of crude oil leakage detection, and avoid the existing phenomenon of untimely oil leakage detection and missed or misjudgment.

[0030] Furthermore, in the present embodiment, in order to ensure that the intensity of ultraviolet rays emitted by the ultraviolet generating device meets the requirements, and in order to utilize the ultraviolet rays in natural light and reduce the use cost of the ultraviolet generating device, it is preferred that the ultraviolet generating device 2 includes an ultraviolet radiation intensity detection unit 25, which is arranged on one side of the ultraviolet emitting module 21, and is used to detect the intensity of ultraviolet rays emitted by the ultraviolet emitting module 21, and is used to detect the ultraviolet intensity in the current environment. When the ultraviolet intensity in the current environment meets the requirements, it is not necessary to start the ultraviolet emitting module 21 when acquiring the filtered image irradiated by ultraviolet rays; in the present embodiment, the ultraviolet radiation intensity detection unit 25 Preferably, it is an existing ultraviolet irradiator, and the model of the ultraviolet irradiator is preferably but not limited to LS129-UV-254, the power range of the ultraviolet irradiator of this model is 0-20000uW / cm2, it adopts a digital probe, has an RS485 communication interface, supports the standard MOBUS communication protocol, and can be connected to the PLC to read data, that is, the ultraviolet irradiator of this model meets the requirements of this embodiment. In this embodiment, in order to save the use cost, it is preferred to regularly detect the ultraviolet intensity of the ultraviolet emitting module 21, and the ultraviolet irradiator is only used during the detection. At the same time, the ultraviolet irradiator can detect the ultraviolet intensity of multiple ultraviolet emitting modules 21.

[0031] Furthermore, in the present embodiment, in order to improve the safety performance of the detection system, the ultraviolet generating device 2 preferably further includes a living organism detection module 26 and an alarm module 27, both of which are fixed in the ultraviolet cover and electrically connected to the control unit 3. In the present embodiment, the living organism detector includes at least one of an acoustic wave detection unit or an infrared detection unit. Before starting the ultraviolet emission module 21, the living organism detection module 26 is used to detect whether there is a person or animal intruding into the irradiation area 5, so as to prevent people or animals from mistakenly entering the irradiation area 5 and being harmed by ultraviolet rays. In the present embodiment, the alarm module 27 includes at least one of a sound alarm and a light alarm. The alarm module 27 can be used for remote or on-site alarms. On the one hand, it can warn people or animals to stay away from the irradiation area 5, and on the other hand, it can remind nearby staff that there is an oil leak in the current oil pump, so that nearby staff can Nearby staff can deal with the oil leakage in time. In this embodiment, in order to enable the staff to accurately judge the alarm intention, the alarm intention can be distinguished by setting the alarm duration or alarm content. For example, a short time interval alarm represents a warning to personnel or animals to stay away from the irradiation area 5, and a long time interval alarm represents that there is an oil leakage in the oil pump. The specific settings can be based on actual use, and this embodiment does not make any limitations. When in use, when the living biological detector detects that no person or animal has entered the irradiation area 5, the controller can start the ultraviolet emission module 21. When the living biological detector detects that someone or animal has entered the irradiation area 5, the controller controls the alarm module 27 to sound an alarm to warn people or animals to stay away from the irradiation area 5. At the same time, the ultraviolet emission module 21 is not started. Alternatively, when an oil leakage is detected, the controller controls the alarm module 27 to sound an alarm to remind nearby staff to deal with the oil leakage in time.

[0032] Furthermore, in this embodiment, in order to improve the safety performance of the detection system, the ultraviolet generating device 2 preferably includes an acceleration sensor module, which is electrically connected to the control unit 3. The acceleration sensor module can sense whether the ultraviolet generating device 2 is tilted to ensure that the irradiation area 5 corresponds to the collection area 6, and avoid the ultraviolet generating device 2 tilting to cause the irradiation area 5 to move outside the collection area 6, thereby affecting the collection precision and accuracy of the image collection device.

[0033] Embodiment 2:

In this embodiment, the steering assembly includes a gear transmission mechanism 22 and a driving mechanism 23, and a transmission shaft 24 is connected to the gear transmission mechanism 22. The ultraviolet generating device 2 is arranged at the free end of the transmission shaft 24. In this embodiment, it is preferred that the steering assembly drives the ultraviolet emitting module 21 to rotate left and right to change the irradiation area 5 (the upper and lower irradiation ranges are fixed), see Fig. 9 ; In this embodiment, the gear transmission mechanism 22 is preferably a double gear transmission mechanism 22. In this embodiment, the driving mechanism 23 is preferably a stepper motor and a stepper motor driving module. The stepper motor driving module is electrically connected to the I / O port of the controller. When in use, the controller sends an enable signal to the stepper motor driving module. The stepper motor driving module receives the enable signal from the controller, and then starts the stepper motor after processing the enable signal, and feeds back the working condition of the stepper motor to the controller. The rotation of the stepper motor will drive the transmission shaft 24 to rotate synchronously and then drive the ultraviolet generating device 2 to rotate. See Fig.10 In this embodiment, the angle of each rotation of the ultraviolet generating device 2 can be preset in the controller. In this embodiment, the irradiation area 5 changed by the rotation of the ultraviolet generating device 2 is located in the acquisition area 6 of at least one group of image acquisition devices 1, that is, one ultraviolet generating device 2 can irradiate the acquisition areas 6 of multiple image acquisition devices 1, which can reduce the number of ultraviolet generating devices 2 used and reduce the use cost of the ultraviolet generating device 2.
