Description

Technical Field

[0001] The present invention belongs to the field of lasers, and particularly relates to a laser warning system and a laser. Background Art

[0002] Due to the increasing volume of lasers in the market nowadays, and the continuously increasing power of lasers, their failure rates are correspondingly getting higher and higher. In order to maintain a large customer base, the scale of after-sales service is also getting larger and larger, the cost is getting higher and higher, the maintenance duration is getting longer and longer, and the maintenance difficulty is getting greater and greater. This is extremely unfavorable for the efficient operation of laser enterprises and also for the reputation of the enterprises. Most of the lasers in the market nowadays are independent individuals, that is, once a certain laser fails, it can only display a fault code on the laser, and even most lasers do not even have a fault code. Once a failure occurs, only after-sales personnel can be contacted to come to the door for service, and then one-by-one detection is carried out. This not only has low efficiency but also incurs extremely high costs. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 is a schematic diagram of the laser warning system provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In order to illustrate the technical solutions described in the present invention, the following will be described through specific embodiments.

[0020] Please refer to Figure 1 , the laser warning system provided by the embodiment of the present application includes a processor 11, a pressure detection module 12, a communication module 13, and a storage module 14 that are respectively connected to the processor 11. Among them, the pressure detection module 12 is used to collect the pressure data at the inlet and outlet of the pipeline of the cooling plate in the laser; the processor 11 is used to calculate the pressure drop data between the inlet and the outlet according to the pressure data; the storage module 14 is used to store the pressure drop data each time when the device is turned on and used; the communication module 13 is used to send the pressure drop data to the cloud server, so that the cloud server can analyze the change trend of the pressure drop data of the laser according to the pressure drop data, predict whether the laser will fail, and issue a warning if it will fail.

[0021] In the embodiment of the present application, the pressure detection module 12 may include a first pressure sensor and a second pressure sensor; the first pressure sensor is installed at the inlet of the pipeline of the cooling plate in the laser and is used to obtain the pressure at the inlet; the second pressure sensor is installed at the outlet of the pipeline of the cooling plate in the laser and is used to obtain the pressure at the outlet.

[0022] It can be understood that the pressure drop data is obtained by subtracting the pressure at the outlet of the cooling plate pipeline from the pressure at the inlet of the cooling plate pipeline. For a laser, the pressure drop of the cooling plate (i.e., the pressure loss when the coolant flows through the water cooling plate) is an important parameter for evaluating the performance, efficiency, and reliability of its heat dissipation system. When the pressure drop at the inlet and outlet of the cooling plate in the system is large, the flow rate decreases, resulting in a decrease in the heat transfer coefficient, and thus insufficient heat dissipation effect for the laser; if the pressure drop is too small, the energy consumption may increase due to too high a flow rate. In addition, the pressure drop state can also be used to reflect the situation of blockage or leakage in the cooling plate pipeline.

[0023] In this application, by analyzing the change trend of the pressure drop data of the laser through the pressure drop data of the cooling plate, the change of the internal fluid flow state of the cooling plate can be detected more acutely. When the laser is working, problems such as minor blockage, scaling, or pipeline deformation in the cooling plate may not cause an obvious change in the pressure at a certain measurement point (such as the inlet), but will cause an increase in the resistance of the fluid flowing through the cooling plate, a decrease in the pressure at the outlet, and thus a significant change (specifically an increase) in the pressure drop, which can provide an early warning for potential failures of the laser earlier.

[0024] Moreover, the pressure drop data adopted in this application is a relative value, specifically the difference between the inlet and outlet pressures of the cooling plate. To a certain extent, it can offset part of the influence of environmental factors, is relatively less interfered by environmental factors, can more stably and reliably reflect the actual working state of the cooling plate, and provides a more accurate basis for the early warning judgment of the laser.

[0025] In this application, the processor is specifically used to calculate the difference between the pressure at the inlet and the pressure at the outlet of the pipeline as the pressure drop data according to the pressure at the inlet and the pressure at the outlet of the pipeline. In this way, based on the accurate pressure drop data obtained, the change trend of the pressure drop data of the laser is analyzed. Once an abnormality in the real-time pressure drop data is detected, the system immediately triggers an early warning mechanism and sends detailed fault prompt information to the operation and maintenance personnel, including possible fault types (such as minor blockage, local scaling, etc.) and potential risk level assessment.

[0026] In the embodiment of this application, the laser early warning system may further include a temperature sensor 15 connected to the processor for obtaining the temperature data of the pump source in the laser; The storage module 14 is further used to store the temperature data of the pump source obtained each time when starting up and using; The communication module 13 is further used to send the temperature data of the pump source to the cloud server, so that the cloud server analyzes the change trend of the temperature data of the pump source of the laser according to the obtained temperature data of the pump source, predicts whether the laser will have a fault, and if a fault will occur, issues an early warning.

[0027] The laser warning system may further include a flowmeter 16 connected to the processor; The flowmeter 16 is installed in the pipeline of the cooling plate in the laser, and is used to obtain the flow data of the cooling medium in the pipeline; The storage module 14 is further used to store the flow data of the cooling medium obtained each time the laser is turned on and used; The communication module 13 is further used to send the flow data of the cooling medium to the cloud server, so that the cloud server analyzes the change trend of the flow data of the cooling medium of the laser according to the obtained flow data of the cooling medium, predicts whether the laser will fail, and if it will fail, issues a warning.

[0028] The laser warning system may further include an optical power detection module 17 connected to the processor for obtaining the output optical power intensity of the laser; The storage module 14 is further used to store the output optical power intensity obtained each time the laser is turned on and used; The communication module 13 is further used to send the output optical power intensity to the cloud server, so that the cloud server analyzes the change trend of the output optical power intensity of the laser according to the obtained output optical power intensity, predicts whether the laser will fail, and if it will fail, issues a warning.

[0029] The laser warning system may further include a display module connected to the processor.

[0030] In the embodiment of the present application, the cooling medium of the cooling plate may be a liquid.

[0031] In the embodiment of the present application, the cloud server analyzes the data trend of the laser according to the obtained pressure drop data, the temperature data of the pump source, the flow data of the cooling medium, and the output optical power intensity, predicts whether the laser will fail, and if it will fail, issues a warning. Specifically, it may include: For the temperature data of the pump source:

[0032] Among them, ΔT N is the temperature difference between the last two tests, ΔT N-1 is the temperature difference between the first two tests. If ΔT N >ΔT N-1 , the cloud server issues a warning to prompt the data center personnel that this laser needs attention. If continuous alarms occur, that is, ΔT N always shows an upward trend, the cloud server issues a warning to the after-sales personnel or the user of this laser, and continued use will cause damage to the pump source of the laser and burn the pump. It is recommended that the after-sales personnel come to repair on site; among them, T nrepresents the pump source temperature at the nth time, T n-1 represents the pump source temperature at the (n - 1)th time, T n-2 represents the pump source temperature at the (n - 2)th time; For the flow rate data of the cooling medium: When Q n -Q n-1 < -A, where A is a preset value, which can be set to different values according to different water-cooled machines and different lasers. A smaller laser can be set to 1 Lpm, and a larger laser can be set to 2 Lpm or higher. When the flow rate of the latter time is continuously decreasing compared to the previous time for multiple times, there may be a problem of cooling medium leakage; where Q n represents the flow rate data at the nth time, Q n-1 represents the flow rate data at the (n - 1)th time; For the pressure drop data: When there are multiple times of P n >P n-1 it means that there are impurities in the water-cooling system, the water channel is blocked, and it is deteriorating continuously. It is necessary to prompt the user to clean the water channel or let the after-sales personnel come to clean it; where P n represents the pressure drop data at the nth time, P n-1 represents the pressure drop data at the (n - 1)th time; For the output optical power intensity Wn: When W n < the rated output power of the laser, it means that the power of the laser has decreased, and there may be a phenomenon of chip burning. It can be accurately judged based on the pump source temperature data at the same time. According to the amount of decrease of W n the specific number of burned chips can be judged. If W n = 0, then there may be a phenomenon of optical fiber burnout.

[0033] In the embodiment of the present application, the communication module 13 can be a WIFI module, an NB-IoT module, an Ethernet module, a cellular mobile communication module, etc.

[0034] The embodiment of the present application also provides a laser, including the laser warning system provided by the embodiment of the present application.

[0035] In this application, since the laser warning system includes a pressure detection module, a temperature sensor, a flowmeter, an optical power detection module, and a communication module, the communication module is used to send the pressure drop data, the temperature data of the pump source, the flow rate data of the cooling medium, and the output optical power intensity of the laser to the cloud server, so that the cloud server can analyze the data change trend of the laser based on the pressure drop data, the temperature data of the pump source, the flow rate data of the cooling medium, and the output optical power intensity of the laser, and predict whether the laser will malfunction. Therefore, it is beneficial to predict the life of each laser in advance intelligently, predict the components that will be damaged in advance, reduce the failure rate of the laser, reduce the damaged components of the laser, reduce the replacement frequency, reduce resource waste, increase the service life of the laser, greatly reduce the scale cost of after-sales personnel, and improve customer satisfaction.
