Description

Technical Field

[0001] This invention relates to the field of laser ignition, and in particular to a laser remote intelligent ignition device and laser equipment. Background Technology

[0002] In oil and gas exploration, to eliminate the adverse effects of flammable gases such as carbon monoxide, ammonia, hydrogen sulfide, and phosphine emitted from the wellbore on the surrounding environment and personnel, it is necessary to safely, reliably, and promptly ignite and burn these flammable gases. Currently, ignition can be achieved through methods such as a fuel pan flame, a magic bullet, and an automatic high-pressure ignition and combustion control device. However, a fuel pan flame can only burn for 3 hours after a single fuel addition, after which the well must be shut down for refueling, which carries risks such as slipping and falling from heights, burns, and environmental pollution. Magic bullets have poor reliability and cannot be used continuously. Automatic high-pressure ignition and combustion control devices have a short operating range and high heat radiation.

[0048] In oil and gas exploration, to eliminate the adverse effects of flammable gases such as carbon monoxide, ammonia, hydrogen sulfide, and phosphine emitted from the wellbore on the surrounding environment and personnel, it is necessary to safely, reliably, and promptly ignite and burn these flammable gases. However, manual, close-range ignition may lead to safety accidents and is unreliable, making continuous operation impossible.

[0049] Therefore, this invention proposes a laser remote intelligent ignition device.

[0050] Reference Figure 1 In one embodiment of the present invention, the laser remote intelligent ignition device includes:

[0051] Laser emitting host 10, used to emit laser;

[0052] The variable-pitch device 20 is used to receive the laser emitted by the laser emitting host 10 at its laser input end. The variable-pitch device 20 is used to focus and change the pitch of the laser emitted by the laser emitting host 10 and then emit it through the emission point.

[0053] The control device 30 is used to receive aiming signals and control the emission point of the variable-range device 20 to aim at the target point according to the aiming signals, and to control the emission point of the laser emitting host 10 to aim at the laser input end of the variable-range device 20.

[0054] In this embodiment, the laser emitting host 10 can be composed of a laser medium, a pump source, an optical resonant cavity, optical elements, and a control circuit. The laser emitting host 10 can generate a laser beam and emit a laser of a certain intensity to a target object, which can ignite the target object. The target object can be fuel, such as combustible gas, or combustible materials such as wood or leaves. The variable-range device 20 can be composed of one or more optical output lenses, such as lenses. In this way, the parallel light emitted by the laser emitting host 10 can be changed through the lens to change the optical path, thereby focusing it on a point. Multiple lenses with different focal lengths and different distances between the lenses will affect the distance between the focused point and the emission point of the variable-range device 20. Therefore, the variable-range device 20 can change the focusing distance of the laser emitted by the laser emitting host 10 by changing the distance between the lenses or the focal length of the lenses.

[0055] In practical applications, considering energy loss and cost during laser emission, a distance of approximately 200 meters can typically be achieved using the pitch-changing device 20, which meets the needs of most users. If a longer ignition distance is required, multiple lenses can be incorporated into the pitch-changing device 20 according to actual needs. It is understandable that for ignition at a target point of approximately 200 meters, due to the angle between the laser remote intelligent ignition device and the target point, a range of approximately 30 meters from the laser remote intelligent ignition device can generally be considered a safe zone, preventing irradiation by the laser emitted by the device. The safe zone will vary depending on the distance between the laser remote intelligent ignition device and the target point, and the angle of rotation of the device when emitting the laser. The above range is for reference only, and the embodiments in this specification do not impose limitations on this range.

[0056] The control device 30 can be composed of a controller 32 or a control chip, etc. The aiming signal received by the control device 30 can be output through an auxiliary aiming device, such as a tablet computer or other device that accompanies the laser remote intelligent ignition device to aim and determine the position of the target point and output the aiming signal. In practical applications, the position and distance of the target point may change. At this time, the control device 30 can control the laser emitting host 10 and the pitch-changing device 20 to change the angle so that the laser emitting host 10 and the pitch-changing device 20 continue to maintain the same direction, that is, the emission point of the laser emitting host 10 is aimed at the laser input end of the pitch-changing device 20. This can ensure that the laser can be emitted to the target point with maximum power. If the pitch-changing device 20 is composed of a lens, the laser input end of the pitch-changing device 20 can be a side of a lens close to the laser emitting host 10.

[0057] The technical solution of this invention comprises a laser remote intelligent ignition device consisting of a laser emitting host 10, a pitch-changing device 20, and a control device 30. The laser emitting host 10 emits a laser; the pitch-changing device 20 focuses and adjusts the pitch of the laser emitted by the laser emitting host 10 before emitting it through the emission point; the control device 30 receives aiming signals and controls the emission point of the pitch-changing device 20 to aim at the target point, as well as controls the emission point of the laser emitting host 10 to aim at the laser input end of the pitch-changing device 20. This allows for aiming and ignition of distant targets with a long duration, and prevents burns at close range even during long-distance ignition.

[0058] In one embodiment, the control device 30 includes:

[0059] Memory 31 stores the target cruise program;

[0060] The controller 32 is electrically connected to the memory 31. The controller 32 is used to control the laser remote intelligent ignition device to perform cruise ignition on the target on the preset path when executing the target cruise program.

[0061] In this embodiment, the memory 31 can be an E2PROM or DDR3 type memory, which can store the target point navigation program. The controller 32 can be a digital signal processor (DSP), programmable logic device (PLD), field-programmable gate array (FPGA), microprocessor, MCU, or other electronic components. The laser remote intelligent ignition device can also be equipped with a high-precision electric gimbal to support multiple target point preset positions, enabling automatic navigation between multiple target points. For example, eight navigation paths can be preset, with 10 navigation points per path, resulting in 80 target points. This allows for active searching for combustible gases, addressing the problem of difficulty in ignition due to different release pressures and uneven distribution of combustible gases. The gimbal can use a worm gear drive, ensuring reliable self-locking in the event of power failure. Furthermore, the more target points there are, the higher the probability of finding combustible gases. Specifically, the controller 32 can execute the target cruise program in the memory 31 to control the laser emitting host 10 in the laser remote intelligent ignition device to emit lasers to the target in a preset order for ignition.

[0062] In one embodiment, the control device 30 further includes:

[0063] The wireless communication circuit 33 is used to communicate with the server terminal and receive environmental parameters output by the server terminal.

[0064] The controller 32 is also used to receive environmental parameters output by the wireless communication circuit 33 and update the cruise program in the memory 31 according to the environmental parameters.

[0065] In this embodiment, the wireless communication circuit 33 can be constructed using electronic components such as wireless communication chips, resistors, and capacitors. This wireless communication circuit 33 can communicate with the server terminal and receive wireless signals output by the server terminal. The wireless signals output by the server terminal can be environmental parameters related to the surrounding environment. Specifically, environmental parameters can be detected by sensors, uploaded to the server terminal, and then the server terminal outputs wireless signals representing these environmental parameters to the wireless communication circuit 33. The controller 32 can then determine the possibility of toxic or flammable gases present along the cruise path based on the environmental parameters output by the wireless communication circuit 33, thereby updating the remaining route and cruise points in the cruise program. For example, if the controller 32 detects that the concentration of flammable gas at one or more existing cruise points is lower than a preset concentration based on environmental parameters, the controller 32 can determine that the flammable gas concentration at those points is low and will not adversely affect the surrounding environment or personnel. Furthermore, the controller 32 can select points with higher flammable gas concentrations as new cruise points to replan the cruise path. The specific preset concentration standard can be set according to different user needs.

[0066] In one embodiment, the pitch control device 20 includes:

[0067] Zoom lens group 21, which is used to zoom the laser emitted by the laser emitting host 10 and then emit it to the target point;

[0068] The rangefinder 22 is electrically connected to the control device 30. The rangefinder 22 is used to measure the distance between the zoom lens group 21 and the target point, and outputs the corresponding distance measurement signal to the control device 30.

[0069] The control device 30 is used to adjust the focal length of the zoom lens group 21 according to the ranging signal.

[0070] In this embodiment, the zoom lens group 21 can be composed of one or more focusing lenses, which can change the optical path of the parallel light emitted by the laser emitting host 10 through the lenses, thereby focusing it onto a single point. Factors such as multiple lenses with different focal lengths and different distances between the lenses will affect the distance between the focused point and the emission point of the zoom device 20. Therefore, the zoom device 20 can change the focusing distance of the laser emitted by the laser emitting host 10 by changing the distance between multiple focusing lenses or the focal length of the focusing lenses. The rangefinder 22 is a tool for measuring length or distance, and the specific model can be selected according to user needs. For example, the rangefinder 22 can be divided into short-range, medium-range, and high-range rangefinders based on its measuring range, and into photoelectric rangefinders and acoustic rangefinders based on the modulation object used. This solution does not restrict the selection of the rangefinder 22. The rangefinder 22 can be positioned either flush with or close to the zoom lens assembly 21. Thus, the distance measured by the rangefinder 22 to the target point can also represent the distance between the zoom lens assembly 21 and the target point. The control device 30 can adjust the focal length of the zoom lens assembly 21 based on the ranging signal output by the rangefinder 22, ensuring that the laser emitted by the laser transmitter 10 is accurately emitted to the target point via the zoom lens assembly 21. As described in the above embodiment, there are multiple different target points along the cruising path, and the distances between these target points and the laser remote intelligent ignition device vary. Therefore, it is necessary to measure the distance using the rangefinder 22 and then adjust the focal length of the zoom lens assembly 21.

[0071] In one embodiment, the laser remote intelligent ignition device further includes:

[0072] A safety alarm device is electrically connected to the control device 30. The safety alarm device is used to emit a detection laser parallel to the laser emitted by the laser emitting host 10, and outputs an alarm signal and issues an alarm message when an object is detected entering the detection laser range.

[0073] The control device 30 is used to control the laser emitting host 10 to stop emitting laser when it receives the alarm signal.

[0074] In this embodiment, the safety alarm device may include a laser emitter and a laser receiver. The laser emitter emits laser light, and the laser receiver receives the laser light, thus forming a parallel laser fence on both sides of the laser beam path emitted by the laser emitting host 10. When an object is detected to have intruded, i.e., touched by the laser fence, an alarm signal is output to the control device 30. For example, if a person or animal touches the laser fence, the laser receiver cannot receive the laser light emitted by the laser emitter. In this case, an electrical signal, i.e., an alarm signal, can be output to the control device 30. The control device 30 can control the laser emitting host 10 to immediately stop emitting laser light to avoid safety accidents, because the laser emitted by the laser emitting host 10 is a high-power laser, which may cause damage to the human body or other objects when it shines on them. The safety alarm device may also include devices such as LED lights or buzzers to issue an alarm message when an object is detected entering the detection laser range. For example, a red LED light or an LED light of another color can be used to control the LED light to light up as an alarm message, or the LED light can be controlled to flash; the buzzer may also emit a high-decibel sound. The process of issuing an alarm message can specifically be that when the control device 30 receives the alarm signal, it controls the LED light to light up or controls the buzzer to sound; it can also be that a switching circuit is set up to power the LED light or the buzzer when an object is detected entering the detection laser range; or it can issue an alarm message in other ways, and this solution does not limit it.

[0075] In one embodiment, the laser remote intelligent ignition device further includes:

[0076] The indicator laser emitting device 40 is electrically connected to the control device 30. The control device 30 is also used to control the indicator laser emitting device 40 to emit an indicator laser parallel to the laser emitted by the laser emitting host 10 when the emission point of the variable pitch device 20 is aimed at the target point.

[0077] The video monitoring device 50 is electrically connected to the control device 30. The video monitoring device 50 is used to acquire environmental image information within a preset range of the laser remote intelligent ignition device and / or environmental image information within a preset range of the target point, and output environmental image signals to the control device 30.

[0078] The display device 60 is electrically connected to the control device 30, and the control device 30 is used to control the display device 60 to display environmental information according to the environmental image signal.

[0079] In this embodiment, the indicator laser emitting device 40 can also be a laser emitter. The emitted laser will not cause harm to the human body. To make it easier for people to notice, a green or other colored laser can also be used. The indicator laser emitting device 40 emits an indicator laser parallel to the laser emitted by the laser emitting host 10, which can serve as a reminder, so that when someone passes by the laser remote intelligent ignition device, they will notice the laser and not approach the laser beam path emitted by the laser emitting host 10.

[0080] The video monitoring device 50 may include one or more cameras and other devices to acquire environmental image information within a preset range of the laser remote intelligent ignition device, or environmental image information within a preset range of a target point, and then output the corresponding environmental image signal to the control device 30. The control device 30 can then control the display device 60 to display the corresponding environmental information, allowing users to observe the environmental information around the target point in real time. The control device 30 can also output the environmental image signal to the cloud or server terminal via the wireless communication circuit 33, enabling remote personnel to view the environmental image information within the preset range of the laser remote intelligent ignition device or the preset range of the target point. The preset range distance is related to the camera model selection; users can choose a camera with the appropriate viewing distance according to their actual needs.

[0081] In one embodiment, the laser remote intelligent ignition device further includes:

[0082] A short-range communication circuit is electrically connected to the control device 30, and the control device 30 establishes a communication connection with a user terminal within a first distance through the short-range communication circuit;

[0083] A long-distance communication circuit is electrically connected to the control device 30. The control device 30 establishes a communication connection with a user terminal within a second distance through the long-distance communication circuit, where the second distance is greater than the first distance.

[0084] In this embodiment, the user can also remotely control the laser remote intelligent ignition device through a user terminal, which can be a tablet computer or other device. The user terminal and the laser remote intelligent ignition device need to communicate via a communication circuit. This embodiment provides a short-range communication circuit, such as communication via Wi-Fi or Bluetooth, typically enabling communication within a 1-kilometer range. A long-range communication circuit, such as communication via 4G or 5G, also exists, offering a longer communication range. However, long-range communication is more expensive. Therefore, when the user holds the user terminal and is close to the laser remote intelligent ignition device, a short-range communication circuit can be used to establish the communication connection between the two devices; this communication method is more flexible. Therefore, in this embodiment, the second distance is greater than the first distance.

[0085] In one embodiment, the laser remote intelligent ignition device further includes a flame sensor, and the device has an automatic mode and a manual mode. The flame sensor is a device used to detect the presence of a flame. It can identify specific wavelengths in the spectrum associated with flame characteristics and indicate the presence of a flame through electrical signals or other forms of output. The flame sensor can be implemented using different working principles and technologies, such as photosensitive sensors, infrared sensors, ultraviolet sensors, and thermal sensors. In manual mode, the user can manually control the laser remote intelligent ignition device to emit a laser for ignition, or control the device to stop emitting the laser. In automatic mode, the device can remotely identify flames in the flameout pool: it automatically stops emitting the laser when the flame is burning and restarts emitting when the flame is extinguished, thus achieving energy savings; if there is no flame, it can continuously output laser light.

[0086] Furthermore, the laser remote intelligent ignition device can adjust the output laser power, improving reliability and energy efficiency. For example, it can identify the flame size and reduce the output laser power when the flame is large, and increase the output laser power when the flame is small.

[0087] In one embodiment, the laser remote intelligent ignition device further includes:

[0088] The positioning module is used to determine the location information of the laser remote intelligent ignition device and output the location signal to the user terminal through the short-range communication circuit or the long-range communication circuit.

[0089] In this embodiment, the positioning module can be a GPS positioning module, which can be used to determine the location information of the laser remote intelligent ignition device and output the location signal to the user terminal through the short-range communication circuit or long-range communication circuit in the above embodiment. It is understood that, under special circumstances, if personnel near the laser remote intelligent ignition device lose contact with the person holding the user terminal, the person holding the user terminal can determine the location of the laser remote intelligent ignition device through the location signal output by the positioning module in the laser remote intelligent ignition device.

[0090] In one embodiment, the laser remote intelligent ignition device further includes:

[0091] The power supply circuit has an input terminal for connecting to the AC power grid, and an output terminal for connecting to the power input terminal of the laser emitting host 10, the power input terminal of the pitch-changing device 20, and the power input terminal of the control device 30. The power supply circuit is used to convert the AC voltage output from the AC power grid into a working voltage to supply power to the laser emitting host 10, the pitch-changing device 20, and the control device 30.

[0092] An auxiliary power supply, the output of which is connected to the power input of the laser emitting host 10, the power input of the pitch-changing device 20, and the power input of the control device 30.

[0093] The power management module is electrically connected to the power circuit and the auxiliary power supply. The power management module is used to control the auxiliary power supply to supply power to the laser emitting host 10, the pitch-changing device 20 and the control device 30 when the output voltage of the power circuit is detected to be less than a preset voltage value.

[0094] In this embodiment, the power supply circuit can be an AC-DC power supply circuit or an AC-AC power supply circuit, etc. The power supply circuit is connected to the AC power grid and can convert the 220V high-voltage AC power output from the AC power grid into DC voltage or low-voltage AC power to supply power to the laser transmitter 10, the pitch converter 20, and the control device 30. Whether it is converted into DC voltage or AC voltage can be selected according to the voltage type required by the laser transmitter 10, the pitch converter 20, and the control device 30.

[0095] The auxiliary power supply can be one or more lithium iron phosphate batteries, or lead-acid batteries, etc. The power management module can include a power management chip and other electronic components. When the power management module detects that the output voltage of the power circuit is less than the preset voltage value, such as when the AC mains is disconnected from the power circuit or when the power circuit malfunctions, the power management module can control the auxiliary power supply to supply power to the laser emitting host 10, the pitch converter 20, and the control device 30, thereby ensuring that the laser remote intelligent ignition device can work normally.

[0096] In another embodiment, multiple solar cells can be installed to store electrical energy. In the event of a disconnection between the AC power grid and the power supply circuit, a fault in the power supply circuit, or insufficient auxiliary power, the solar cells can also supply power to the communication circuit, video monitoring device 50, and positioning module in the laser remote intelligent ignition device.
