Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and in particular to a control method, device, terminal equipment and storage medium for a laser lamp. Background Art

[0002] Laser light source is a light source that uses the principle of stimulated radiation to generate a high-brightness, high-directional light beam. It has the characteristics of good monochromaticity, strong coherence, and high brightness, so it has been widely used in many fields. The shaking head laser light source is based on the laser light source, and the light beam emitted by it can swing or rotate within a certain range through mechanical or electronic means, thereby achieving dynamic light effects. This light source is widely used in stage performances, architectural lighting, outdoor advertising and other fields, and can create colorful visual effects and enhance the attractiveness of performances or displays. However, the high-intensity light beam of laser lamps can directly increase the temperature of the irradiated area, which may cause serious damage to human skin and eyes. In addition, when encountering obstacles within a short distance, laser lamps may also heat up rapidly, causing fires. Due to the dynamic pointing characteristics of the light beam, shaking head lamps are more likely to have light spots hit the human body or flammable objects, increasing safety hazards.

[0003] In order to avoid these hazards, warning labels are usually attached to the outside of the lamps when they are used, telling users to keep a safe distance. However, in places where stage lighting is used, there are often dense crowds of people, and it is difficult for audiences and actors to notice these subtle warning labels. They are prone to being exposed to close range for a certain period of time without knowing it, which poses a major safety hazard. Summary of the invention

[0004] The present invention aims to provide a control method, device, terminal equipment and storage medium for a laser lamp to solve the above-mentioned technical problems, improve the safety and reliability of the laser light source during use, and avoid potential safety hazards.

[0005] In order to solve the above technical problems, the present invention provides a control method for a laser lamp, comprising:

[0006] Generate a human eye safety irradiation distance of the laser lamp and an obstacle safety irradiation distance at different output powers according to the working parameters of the laser lamp, and construct a safety distance relationship set based on the human eye safety irradiation distance and the obstacle safety irradiation distance;

[0007] When the laser lamp is powered on, performing environmental detection on the laser lamp based on a sensor device installed on the laser lamp;

[0008] When foreign matter exists in the environmental detection result, a traversal query is performed in the safety distance relationship set according to the irradiation distance of the laser lamp when the foreign matter is detected, and a preset laser lamp safety control strategy is executed when the irradiation distance exceeds the corresponding safety distance.

[0009] In the above scheme, the safe irradiation distance for human eyes and the safe irradiation distance for obstacles are generated according to the working parameters of the laser lamp, and a safe distance relationship set is constructed. The safe distance relationship set based on scientific calculation avoids errors in human judgment, and can dynamically adjust the safe distance according to the actual working parameters and use environment of the laser lamp to ensure safety in different scenarios. Based on the installation of sensor equipment on the laser lamp to detect the surrounding environment in real time, potential dangerous situations can be discovered in time. When there are foreign objects in the environmental detection results, the actual irradiation distance is compared with the safe distance in real time to determine whether safety control measures need to be taken. Through traversal query and real-time comparison, the accuracy of the judgment can be ensured and the risk of misjudgment can be reduced. When the irradiation distance exceeds the safe distance, the preset safety control strategy is executed. Through the pre-built safety control strategy, the most appropriate measures can be selected according to the actual situation to ensure the effectiveness of safety control.

[0010] In one implementation,

[0011] In the above scheme, collecting the working parameters of the laser lamp can ensure data accuracy and unified testing standards. Then, based on the safety standard, the maximum allowable exposure to the human eye is generated to obtain the nominal eye hazard distance, which can ensure that laser exposure will not cause damage to the human eye. The human eye safety exposure distance is set according to the nominal eye hazard distance, thereby ensuring the safety of the laser light source during use.

[0014] Generate the maximum permissible exposure of human eyes under the working parameters based on the laser safety use standards;

[0015] A nominal eye hazard distance is generated according to the maximum allowable exposure to human eyes and the application scenario of the laser lamp; wherein,

[0016] When the laser lamp is a pulsed laser or the divergence angle is greater than a preset angle, the expression for the nominal eye hazard distance is:

[0017]

[0018] Where, d0 is the initial beam diameter of the laser light source; θ is the divergence angle; P is the output power; Δt is the laser pulse duration; MPE is the maximum allowable exposure to the human eye, and ΔA is the area of ​​the initial beam;

[0019] When the laser lamp is a continuous wave laser or the divergence angle is less than the preset angle, the expression of the nominal eye hazard distance is:

[0020]

[0021] Where: a is the effective beam radius of the laser light source; E MPE is the maximum allowable exposure power density; H MPE The maximum allowable exposure; t is the exposure time of the laser;

[0022] The human eye safety exposure distance is set according to the nominal eye hazard distance; wherein the human eye safety exposure distance is greater than the nominal eye hazard distance.

[0023] In the above scheme, by setting the safe ignition point, selecting the irradiated object with strong light absorption and ignition point higher than the safe ignition point, fixing the irradiation time and gradually adjusting the irradiation distance, the obstacle safe irradiation distance of the laser lamp can be effectively measured. This scheme can provide a unified safety distance standard for laser lamps at different powers to ensure the safety of laser irradiation.

[0024] In one implementation, generating the laser lamp and the obstacle safety irradiation distance at different output powers according to the working parameters of the laser lamp specifically includes:

[0026] The laser lamp is fixed at different output powers to perform an irradiation experiment on the irradiated object, to obtain a minimum irradiation distance at which the irradiated object will not reach the safe ignition point within the fixed irradiation time, and the minimum irradiation distance is used as the obstacle safety irradiation distance of the laser lamp at different output powers;

[0027] Among them, the irradiation experiment is to set the irradiated object within the direct range of the laser lamp, fix the initial temperature of the irradiated object, detect whether the irradiated object will reach the safe ignition point within the fixed irradiation time, and when the temperature of the irradiated object reaches the safe ignition point, increase the distance between the irradiated object and the laser lamp until the irradiated object does not reach the safe ignition point within the fixed irradiation time.

[0028] In the above scheme, by setting a safe ignition point lower than the ignition point of conventional objects, it is ensured that even if the beam of the laser lamp shines on the object during the experiment, it will not cause combustion. By setting a safe ignition point lower than the ignition point of conventional objects, it is ensured that even if the beam of the laser lamp shines on the object during the experiment, it will not cause combustion. Experiments are conducted for laser lamps with different output powers to generate corresponding safe irradiation distances to ensure that they can adapt to different working conditions in actual use.

[0033] In the above solution, the infrared sensor can effectively detect the presence of foreign objects, while the laser sensor can accurately measure the distance. The combination of the two can provide comprehensive environmental monitoring. Installing the sensor device on the edge of the shell will not affect the normal operation of the laser lamp, and it is convenient for the maintenance and calibration of the sensor device.

[0034] In one implementation, when there is a foreign object in the environmental detection result, a traversal query is performed in the safety distance relationship set according to the irradiation distance of the laser lamp when the foreign object is detected, and when the irradiation distance exceeds the corresponding safety distance, a preset laser lamp safety control strategy is executed, specifically including:

[0036] The real-time output power of the laser lamp is obtained, and when the type of the foreign object is an obstacle and the irradiation distance is less than the first obstacle irradiation distance corresponding to the real-time output power, a second laser lamp control strategy is executed; wherein the second laser lamp control strategy is to perform a convenient query in the safety distance relationship set based on the irradiation distance, obtain the output power of the laser lamp when the obstacle safety distance is greater than the irradiation distance, and use the output power as the real-time output power of the laser lamp

[0037] In the above scheme, by obtaining the type of foreign matter and the real-time irradiation distance, the safety control strategy of the laser lamp is implemented in a targeted manner to ensure that effective measures can be taken quickly when a human body or obstacle is detected. Specifically, by performing the light-off operation or adjusting the output power, reliable safety protection can be provided under different working conditions.

[0041] The safety control module is used to perform a traversal query in the safety distance relationship set according to the irradiation distance of the laser lamp when the foreign object is detected when foreign matter is present in the environmental detection result, and execute a preset laser lamp safety control strategy when the irradiation distance exceeds the corresponding safety distance.

[0042] In the above scheme, the safe irradiation distance for human eyes and the safe irradiation distance for obstacles are generated according to the working parameters of the laser lamp, and a safe distance relationship set is constructed. The safe distance relationship set based on scientific calculation avoids errors in human judgment, and can dynamically adjust the safe distance according to the actual working parameters and use environment of the laser lamp to ensure safety in different scenarios. Based on the installation of sensor equipment on the laser lamp to detect the surrounding environment in real time, potential dangerous situations can be discovered in time. When there are foreign objects in the environmental detection results, the actual irradiation distance is compared with the safe distance in real time to determine whether safety control measures need to be taken. Through traversal query and real-time comparison, the accuracy of the judgment can be ensured and the risk of misjudgment can be reduced. When the irradiation distance exceeds the safe distance, the preset safety control strategy is executed. Through the pre-built safety control strategy, the most appropriate measures can be selected according to the actual situation to ensure the effectiveness of safety control.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0078] Example 1

[0079] See also Figure 1 , Figure 1The flowchart of a control method of a laser lamp provided in an embodiment of the present invention is shown in FIG. The control method of a laser lamp provided in an embodiment of the present invention includes steps 101 to 103, and each step is specifically as follows:

[0080] Step 101: Generate a human eye safety irradiation distance of the laser lamp and an obstacle safety irradiation distance at different output powers according to working parameters of the laser lamp, and construct a safety distance relationship set based on the human eye safety irradiation distance and the obstacle safety irradiation distance.

[0081] In one embodiment, generating the human eye safety irradiation distance of the laser lamp according to the working parameters of the laser lamp specifically includes: collecting the working parameters of the laser lamp; wherein the working parameters include output power, wavelength, divergence angle and pulse duration;

[0082] Generate the maximum permissible exposure of human eyes under the working parameters based on the laser safety use standards;

[0083] A nominal eye hazard distance is generated according to the maximum allowable exposure to the human eye and the application scenario of the laser lamp; wherein, when the laser lamp is a pulsed laser or the divergence angle is greater than a preset angle, the expression of the nominal eye hazard distance is:

[0084]

[0085] Where, d0 is the initial beam diameter of the laser light source; θ is the divergence angle; P is the output power; Δt is the laser pulse duration; MPE is the maximum allowable exposure to the human eye, and ΔA is the area of ​​the initial beam;

[0086] When the laser lamp is a continuous wave laser or the divergence angle is less than the preset angle, the expression of the nominal eye hazard distance is:

[0087]

[0088] Where: a is the effective beam radius of the laser light source; E MPE is the maximum allowable exposure power density; H MPE The maximum allowable exposure; t is the exposure time of the laser; the human eye safety exposure distance is set according to the nominal eye hazard distance; wherein the human eye safety exposure distance is greater than the nominal eye hazard distance.

[0089] In an embodiment of the present invention, the working parameters of the laser light source in the laser lamp are collected, and the working parameters such as the output power, wavelength, divergence angle and pulse duration of the laser light source are used. Then, with reference to the national laser safety standards (such as the International Electrotechnical Commission IEC 60825-1 standard or the Chinese national standard GB 7247.1), the maximum permissible exposure (MPE) of the human eye under specific wavelength and pulse conditions is calculated. The calculation of the maximum permissible exposure belongs to the conventional technical means in this field and will not be elaborated here. Then, according to the output optical parameters of the laser lamp, that is, the output power, divergence angle, output power and the like in the working parameters, the nominal eye hazard distance NOHD is obtained. Exemplarily, when the application scenarios of the laser lamp are different, the calculation formula for the nominal eye hazard distance NOHD called by it is also different. When the emission angle of the laser beam is large, greater than or equal to 0.01rad, it can be used The calculation formula is applicable to lasers with large divergence angles and rapidly expanding spot sizes, especially pulsed lasers, such as multimode fiber lasers and high-power scattering lasers. Furthermore, when the divergence angle of the laser beam is less than 0.01 rad, the formula can be used The calculation formula is applicable to lasers with small divergence angles and small spot sizes, especially continuous wave lasers such as single-mode fiber lasers. Then, the safe exposure distance for human eyes is set according to the calculated nominal eye hazard distance NOHD. The safe exposure distance for human eyes must be greater than the nominal eye hazard distance NOHD to provide sufficient safety margin. For example, in order to ensure the safety of human eyes, a safety factor is usually added to the nominal eye hazard distance NOHD. The final safe exposure distance for human eyes is generated according to the preset safety factor. The common safety factor range is 1.5 to 2, and the specific selection depends on the scenario and safety requirements of the laser application. When the safety factor = 1.5, it is applicable to general safety environments; when the safety factor = 2, it is applicable to high-risk environments or occasions with higher safety requirements. If the nominal eye hazard distance NOHD is 10 meters and the selected safety factor is 1.5, the safe exposure distance for human eyes = 10 meters × 1.5 = 15 meters.

[0090] In one embodiment, generating the laser lamp and the safe irradiation distance of obstacles at different output powers according to the working parameters of the laser lamp specifically includes: generating experimental parameters according to the historical usage data of the laser lamp; wherein the experimental parameters include a safe ignition point, a fixed irradiation time and an irradiated object; the safe ignition point is lower than the ignition point of conventional items, and the ignition point of prime irradiated objects is greater than the safe ignition point; the laser lamp is fixed at different output powers to perform an irradiation experiment on the irradiated object to obtain a minimum irradiation distance at which the irradiated object will not reach the safe ignition point within the fixed irradiation time, and the minimum irradiation distance is used as the safe irradiation distance of obstacles of the laser lamp at different output powers; wherein the irradiation experiment is to set the irradiated object within the direct irradiation range of the laser lamp, fix the initial temperature of the irradiated object, detect whether the irradiated object will reach the safe ignition point within the fixed irradiation time, and when the temperature of the irradiated object reaches the safe ignition point, increase the distance between the irradiated object and the laser lamp until the irradiated object does not reach the safe ignition point within the fixed irradiation time.

[0091] In an embodiment of the present invention, experimental parameters are generated based on historical usage data of the laser lamp. Among them, the safe ignition point is the highest temperature at which an object will not ignite under laser irradiation. The safe ignition point should be lower than the ignition point of most common objects (such as paper, wood, plastic, etc.). Generally, the safe ignition point can be set to 100 degrees Celsius or lower to ensure safety. The fixed irradiation time can be selected to be 10 seconds or longer to ensure that the cumulative effect of laser irradiation can be fully evaluated. Then, black objects with an ignition point higher than the safe ignition point are used as the irradiated objects. Generally, black rubber and black plastic can be selected. Black rubber has strong light absorption and a higher ignition point. When conducting an irradiation experiment, an initial irradiation distance can be selected, and the laser lamp is directly irradiated onto the irradiated object and continuously irradiated for the set fixed irradiation time, and an infrared thermometer or a contact temperature sensor is used to measure the temperature of the irradiated object. If the temperature reaches or exceeds the safe ignition point, it indicates that the current irradiation distance is not enough to ensure safety, and the irradiation distance, that is, the distance between the laser lamp and the irradiated object, is gradually increased. The test can be repeated by increasing the distance by 10cm each time until the minimum distance that will not cause the irradiated object to reach the safe ignition point within a fixed irradiation time is found. The ignition point is the safe irradiation distance of the obstacle under the output power of the laser lamp. Then change the output power of the laser lamp, repeat the above irradiation test steps for each output power, and measure the corresponding safe irradiation distance of the obstacle under different powers.

[0092] Furthermore, as an optimization scheme of an embodiment of the present invention, taking into account dynamic factors such as zoom adjustment and pattern switching, as well as the influence of different environments (such as stage, indoor, and outdoor), the following improvement measures will be adopted when calculating the nominal eye hazard distance and the obstacle safety irradiation distance of laser lamps at different output powers: select multiple focus positions, and measure the nominal eye hazard distance and obstacle safety irradiation distance at different focal lengths respectively; select multiple commonly used laser irradiation patterns, and measure the nominal eye hazard distance and obstacle safety irradiation distance under different patterns respectively. And test under different environmental conditions: test in a typical indoor environment, record the actual light propagation path and reflection; test in a typical outdoor environment, record the actual light propagation path and environmental conditions; test in an actual performance environment, record the interaction between the laser beam and the actors and props. Construct a safe distance relationship set based on the human eye safety irradiation distance and obstacle safety irradiation distance obtained by the above experiments and calculations.

[0093] Step 102: When the laser lamp is powered on, an environment detection is performed on the laser lamp based on a sensor device installed on the laser lamp.

[0094] In one embodiment, when the laser lamp is powered on, an environmental detection is performed on the laser lamp based on a sensor device installed on the laser lamp, specifically comprising: installing the sensor device on the edge of the shell of the laser lamp; wherein the sensor device includes an infrared sensor and a laser sensor; setting the working mode of the laser lamp according to the working environment of the laser lamp and sending a reset signal to the laser lamp to power on the laser lamp; when the laser lamp is powered on, an environmental detection is performed on the laser lamp based on the infrared sensor and the laser sensor; wherein the infrared sensor is used to detect whether there is a foreign object within the irradiation distance of the laser lamp, and the laser sensor is used to generate the irradiation distance of the laser lamp when the foreign object is detected.

[0095] In the embodiment of the present invention, a sensor device is installed on the edge of the shell of the laser lamp, and the environmental data of the laser lamp when working is detected by the sensor device. It should be noted that when installing the sensor device, it is necessary to ensure that there is no obstruction within the detection range of the sensor device, and the installation angle of the sensor device needs to be adjusted to ensure that the irradiation range of the laser light falls within the signal detection range of the infrared sensor and the laser sensor. Figure 2 , Figure 2The figure is a schematic diagram of the installation of a sensor device on a laser lamp provided in one embodiment of the present invention. The working modes of the laser lamp include indoor mode and outdoor mode. The corresponding working mode needs to be set according to the working environment of the laser mode, so as to retrieve the corresponding safety distance parameters in the safety distance relationship set, so that the laser lamp can apply the safety distance data in the corresponding environment according to different working modes. It should be noted that when the laser lamp is reset outdoors, the lamp head should be quickly pointed vertically downward to avoid the light source being burned due to direct sunlight on the laser light source. In the embodiment of the present invention, a sensor device is installed on each side of the edge of the shell of the laser lamp, and the sensor device faces the irradiation direction of the laser light source. The infrared sensor device detects whether there is a foreign object, that is, a human body or an obstacle, within the irradiation range of the laser lamp. When an obstacle or a human body is detected, the laser sensor feeds back the distance between the laser lamp and the human body / obstacle for subsequent safety distance detection and judgment.

[0096] Step 103: When there is a foreign object in the environmental detection result, a traversal query is performed in the safety distance relationship set according to the irradiation distance of the laser lamp when the foreign object is detected, and a preset laser lamp safety control strategy is executed when the irradiation distance exceeds the corresponding safety distance.

[0097] When there is a foreign object in the environmental detection result, a traversal query is performed in the safety distance relationship set according to the irradiation distance of the laser lamp when the foreign object is detected, and a preset laser lamp safety control strategy is executed when the irradiation distance exceeds the corresponding safety distance, specifically including: obtaining the type of the foreign object, and when the type of the foreign object is a human body and the irradiation distance is less than the safe irradiation distance of the human eye, a first laser lamp safety control strategy is executed; wherein the first laser lamp safety control strategy is to send an alarm signal and perform a light-off operation based on the alarm signal; obtaining the real-time output power of the laser lamp, and when the type of the foreign object is an obstacle and the irradiation distance is less than the first obstacle irradiation distance corresponding to the real-time output power, a second laser lamp control strategy is executed; wherein the second laser lamp control strategy is to perform a convenient query in the safety distance relationship set based on the irradiation distance, obtain the output power of the laser lamp when the obstacle safety distance is greater than the irradiation distance, and use the output power as the real-time output power of the laser lamp.

[0098] In an embodiment of the present invention, when the infrared sensor device detects that there is a foreign object within the irradiation distance of the laser lamp, the laser sensor feeds back the distance between the foreign object and the laser lamp and the type of the foreign object. When there is a human body within the safe irradiation distance of human eyes, the laser sensor sends an alarm signal to the control program of the laser lamp, so that the control program performs a light-off operation based on the alarm signal. If the control program does not receive the alarm signal fed back by the laser sensor, it is determined whether the irradiation distance is less than the obstacle safety irradiation distance corresponding to the current real-time output power according to the irradiation distance fed back by the laser sensor. If it is less than the corresponding obstacle safety irradiation distance, it is necessary to perform a power reduction operation to reduce the real-time output power of the laser lamp to the power value when the irradiation distance is the obstacle safety irradiation distance, otherwise the laser lamp cannot operate safely. Specifically, based on the irradiation distance, a traversal query is performed in the safety distance relationship set to obtain the output power of the laser lamp corresponding to the obstacle when the irradiation distance is greater than and closest to the irradiation distance, and adjust it to the real-time output power of the laser lamp.

[0099] See also Figure 3 , Figure 3 The figure is a schematic diagram of the working principle of a laser lamp provided in one embodiment of the present invention. In the figure, 1 is the actual irradiation range of the laser lamp, and 2 is the continuous scanning range of the infrared sensor. The detection range of the infrared sensor is larger than the irradiation range of the laser lamp. When the infrared radiation signal of the human body is detected within the safe irradiation distance of the human eye, an alarm signal is immediately sent to the control program of the laser lamp. After receiving the alarm signal, the control program executes the light-off operation through the relevant actuator to turn off the laser lamp to avoid harm to the human body. The laser sensor is used to detect the distance between the obstacle and the laser lamp. When the distance when the obstacle is detected is less than the safe distance of the obstacle, the control program gradually reduces the real-time output power of the laser lamp according to the distance when the obstacle is detected, so as to reduce the accumulation of heat on the obstacle and avoid fire. Furthermore, a certain distance emergency threshold can be set accordingly. If the obstacle is too close to the laser lamp, the light-off operation is also triggered.
