Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] In the process of oil and gas exploration, in order to eliminate the adverse effects of combustible gases such as carbon monoxide, ammonia, hydrogen sulfide and phosphine discharged from the wellbore on the surrounding environment and personnel, it is necessary to ignite and burn the discharged combustible gases safely, reliably and promptly. However, manual ignition at close range may cause safety accidents, and has poor reliability and cannot be operated continuously.

[0049] To this end, the present 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 comprises:

[0051] A laser emitting host 10, used for emitting laser;

[0052] A pitch-changing device 20, wherein the laser input end of the pitch-changing device 20 is used to receive the laser emitted by the laser emitting host 10, and the pitch-changing device 20 is used to focus and pitch-change 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 the aiming signal, and control the emission point of the variable distance device 20 to aim at the target point according to the aiming signal, and control the emission point of the laser emission host 10 to aim at the laser input end of the variable distance device 20.

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

[0055] In practical applications, considering the energy loss and cost issues during laser emission, the distance of about 200 meters can usually be achieved through the variable distance device 20, which can meet the user needs in most cases; if the user needs to achieve a farther ignition distance, multiple lenses can be set in the variable distance device 20 according to actual needs. It can be understood that if the target point of about 200 is ignited, since there will be a certain angle between the laser remote intelligent ignition device and the target point, then usually within 30 meters of the laser remote intelligent ignition device, it can be regarded as a safe range and will not be irradiated by the laser emitted by the laser remote intelligent ignition device. The safety range will also change according to the distance between the laser remote intelligent ignition device and the target point and the angle of rotation of the laser remote intelligent ignition device when emitting the laser. The above range is for reference only, and the embodiments of this specification do not limit this.

[0056] The control device 30 may be composed of a controller 32 or a control chip and other devices. The aiming signal received by the control device 30 may be output through an auxiliary aiming device. For example, the laser remote intelligent ignition device is equipped with a tablet computer or other device for aiming and determining the position of the target point and outputting an aiming signal. In actual applications, the position distance of the target point may change. At this time, the control device 30 can control the laser emission host 10 and the variable pitch device 20 to change the angle so that the laser emission host 10 and the variable pitch device 20 continue to remain in the same direction, that is, the emission point of the laser emission host 10 is aimed at the laser input end of the variable pitch device 20, so as to ensure that the laser can be emitted to the target point with maximum power; if the variable pitch device 20 is composed of a lens, the laser input end of the variable pitch device 20 may be a side of a lens close to the laser emission host 10.

[0057] The technical solution of the present invention is a laser remote intelligent ignition device composed of a laser emitting host 10, a pitch-changing device 20 and a control device 30. The laser emitting host 10 can emit lasers; the pitch-changing device 20 can focus and pitch the laser emitted by the laser emitting host 10 and then emit it through the emission point; the control device 30 is used to receive the aiming signal, and control the emission point of the pitch-changing device 20 to aim at the target point according to the aiming signal, and control the emission point of the laser emitting host 10 to aim at the laser input end of the pitch-changing device 20. In this way, aiming and ignition of a distant target point can be achieved, and the duration can be long. In the case of long-distance ignition, there will be no burns at a close distance.

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

[0059] The memory 31 stores a target cruising program;

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

[0061] In this embodiment, the memory 31 can be a memory 31 of the type of E2PROM or DDR3, and the memory 31 can store the target cruise program. The controller 32 can be a digital signal processor (DSP), a programmable logic device (PLD), a field programmable gate array (FPGA), a microprocessor, an MCU single chip or other electronic components. The laser remote intelligent ignition device can also be configured with a high-precision electric pan-tilt to support multiple target preset positions, and can automatically cruise between multiple targets. For example, 8 cruise paths can be preset, each with 10 cruise points, and there are 80 targets. In this way, combustible gas can be actively searched to deal with the problem that it is difficult to ignite due to different deflation pressures and uneven distribution of combustible gas; the pan-tilt can adopt a turbine worm gear drive, which can reliably self-lock when the power is off. And the more targets there are, the higher the probability of finding combustible gas. Specifically, the controller 32 can execute the target cruise program in the memory 31 to control the laser emission host 10 in the laser remote intelligent ignition device to emit laser to the target in a preset order to ignite.

[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 the environmental parameters output by the server terminal;

[0064] The controller 32 is further configured to receive the 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 formed by electronic components such as wireless communication chips, resistors and capacitors. In this way, the wireless communication circuit 33 can realize communication connection with the server terminal and receive the wireless signal output by the server terminal. The wireless signal output by the server terminal can be an environmental parameter about the surrounding environment. Specifically, the environmental parameter can be detected by a sensor, uploaded to the server terminal, and then the wireless signal representing the environmental parameter is output to the wireless communication circuit 33 by the server terminal. In this way, the controller 32 can judge the possibility of the existence of toxic and flammable gas on the cruise path according to the environmental parameters output by the wireless communication circuit 33, thereby updating the cruising path and cruise point in the cruise program; for example, the controller 32 detects that the concentration of flammable gas at the original one or more cruise points is lower than the preset concentration according to the environmental parameters, then the controller 32 can judge that the original one or more cruise points have less flammable gas, which will not have an adverse effect on the surrounding environment or personnel. And the controller 32 can also select a point with a higher concentration of flammable gas as a new cruise point to re-plan the cruise path. The specific preset concentration standard can be set according to the different needs of the user.

[0066] In one embodiment, the pitch changing device 20 comprises:

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

[0068] A rangefinder 22, 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 output a 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, so that the parallel light emitted by the laser emission host 10 can be changed through the lens to change the optical path, so as to focus on one point. Multiple lenses with different focal lengths, and factors such as different distances between lenses will affect the distance between the focused point and the emission point of the variable distance device 20. Therefore, the function of the variable distance device 20 to change the focusing distance of the laser emitted by the laser emission host 10 can be realized by changing the distance between multiple focusing lenses or the focal length of the focusing lens. The rangefinder 22 is a tool for measuring length or distance, and the specific model used can be selected according to user needs. For example, the rangefinder 22 can be divided into short-range, medium-range and high-range rangefinders 22 in terms of range, and can be divided into photoelectric rangefinders 22 and acoustic rangefinders 22 in terms of the modulation object used by the rangefinder 22. There is no restriction on the selection of the rangefinder 22 in this solution. The rangefinder 22 can be set close to the zoom lens group 21, or close to the zoom lens group 21, so that the distance between the rangefinder 22 and the target point can also represent the distance between the zoom lens group 21 and the target point. The control device 30 can adjust the focal length of the zoom lens group 21 according to the distance measurement signal output by the rangefinder 22, so that the laser emitted by the laser emission host 10 can be accurately emitted to the target point through the zoom lens group 21. According to the above embodiments, there are multiple different target points on the cruising path, and the distances between the multiple target points and the laser remote intelligent ignition device are also different. Therefore, it is necessary to measure the distance through the rangefinder 22 and then adjust the focal length of the zoom lens group 21.

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

[0072] A safety alarm device, electrically connected to the control device 30, for emitting a detection laser parallel to the laser emitted by the laser emitting host 10, and outputting an alarm signal and sending an alarm message when an object is detected to enter the detection laser range;

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

[0074] In this embodiment, the safety alarm device may include a laser transmitter and a laser receiver, wherein the laser transmitter transmits the laser and the laser receiver receives the laser, so that parallel laser fences are formed on both sides of the laser light path emitted by the laser transmitter host 10, and when an object is detected to be intruding, that is, when the laser fence is touched, an alarm signal is output to the control device 30; for example, when a person or an animal touches the laser fence, the laser receiver cannot receive the laser emitted by the laser transmitter, and an electrical signal, that is, an alarm signal, may be output to the control device 30, and the control device 30 may control the laser transmitter host 10 to immediately stop emitting the laser to avoid a safety accident, because the laser emitted by the laser transmitter host 10 is a high-power laser, which may cause damage to the human body or other objects when irradiated on the human body or other objects. The safety alarm device may also include devices such as LED lights or buzzers, which are used to issue an alarm message when an object is detected to enter the detection laser range; for example, a red LED light or an LED light of other colors is used to control the LED light to light up as an alarm message, or the LED light may be controlled to flash; the buzzer may also emit a high-decibel sound. The process of issuing an alarm message may specifically be that the control device 30 controls an LED light to light up or controls a buzzer to sound when receiving the alarm signal; or a switch circuit may be set, and when an object is detected to enter the detection laser range, the switch circuit is turned on to power the LED light or the buzzer; the alarm message may also be issued in other ways, which are not limited in this scheme.

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

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

[0077] A video monitoring device 50 is electrically connected to the control device 30, and is used to obtain 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 an environmental image signal 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 indicating laser emitting device 40 can also be a laser emitter, and the emitted laser will not cause damage to the human body. In order to make it easier for people to notice, a green or other color laser can also be used. The indicating laser emitting device 40 emits an indicating 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 will not approach the laser light path emitted by the laser emitting host 10.

[0080] The video monitoring device 50 may include one or more cameras and other devices for collecting and acquiring environmental image information within the preset range of the laser remote intelligent ignition device, and may also acquire environmental image information within the preset range of the target point, and then output the corresponding environmental image signal to the control device 30. The control device 30 may control the display device 60 to display the corresponding environmental information, so that the user can observe the environmental information around the target point in real time. The control device 30 may also output the environmental image signal to the cloud or server terminal through the wireless communication circuit 33, so that the remote personnel can see the environmental image information within the preset range of the laser remote intelligent ignition device or the environmental image information within the preset range of the target point. The distance of the preset range is related to the model selection of the camera, and the user can select a camera with a corresponding shooting distance according to actual needs.

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

[0082] A short-distance communication circuit, 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-distance communication circuit;

[0083] The long-distance 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 second distance through the long-distance communication circuit, and 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 the user terminal, which can be a tablet computer or other device. The user terminal and the laser remote intelligent ignition device need to be connected through a communication circuit. In this embodiment, a short-distance communication circuit is provided, such as communication through WIFI or Bluetooth, which can usually achieve communication within a range of 1 kilometer. And a long-distance communication circuit, such as communication through 4G or 5G, has a longer communication range. However, the cost of long-distance communication is high. Therefore, when the user holds the user terminal and is close to the laser remote intelligent ignition device, a short-distance communication circuit can be used to achieve the communication connection between the laser remote intelligent ignition device and the user terminal; this communication method is more flexible. Therefore, in this embodiment, the second distance will be greater than the range of the first distance.

[0085] In one embodiment, the laser remote intelligent ignition device also includes a flame sensor, and the laser remote intelligent ignition device has an automatic mode and a manual mode. The flame sensor is a device for detecting the presence of a flame. It can identify specific wavelengths in the spectrum that are related to the 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 a photosensitive sensor, an infrared sensor, an ultraviolet sensor, and a thermal sensor. In the manual mode, the user can manually control the laser remote intelligent ignition device to emit a laser for ignition, or control the laser remote intelligent ignition device to stop emitting a laser. In the automatic mode, the laser remote intelligent ignition device can remotely identify the flame in the spray pool: when the flame is burning, it automatically stops emitting the laser, and when the flame is extinguished, it starts emitting again, so that energy saving can be achieved; if there is no flame burning, the laser can be continuously output uninterruptedly.

[0086] In addition, the laser remote intelligent ignition device can also adjust the output laser power to improve reliability and energy saving. For example, it can identify the size of the flame 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] A positioning module, the positioning module is used to determine the position information of the laser remote intelligent ignition device, and output a position signal to a user terminal through the short-distance communication circuit or the long-distance communication circuit.

It is understandable that if under special circumstances, the person near the laser remote intelligent ignition device loses contact with the person holding the user terminal, the person holding the user terminal may 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.

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

[0095] The auxiliary power source may be one or more lithium iron phosphate batteries, or lead-acid batteries, etc. The power management module may include a power management chip and other electronic components.
