[0020] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0021] In the present application, a laser aging detection method is provided. The present application also relates to a laser aging detection device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0022] Figure 1A flow chart of a laser aging detection method provided according to an embodiment of the present application is shown, which specifically includes the following steps: Step S102: In response to the received aging command, receiving a pressure signal of the pressure switch triggered by the laser group to be detected, and in response to the pressure signal, opening the solenoid valve to circulate the cooling water built into the light collecting tube; Step S104: turning on the laser group to be tested, and determining a first aging state according to the flow rate of the cooling water; Step S106: determining a second aging state of the laser group to be detected through an external interface of the laser group to be detected; Step S108: calling the internal status data of the laser group to be detected, and determining the third aging status according to the status data; Step S110: After a preset time period, the aging test stops and the test results are uploaded.

[0023] Among them, Figure 2 A schematic diagram of the structure of a laser aging detection method provided Figure 1 As shown in the hardware structure diagram of the laser aging detection method, laser aging detection is implemented through a laser controller, a light collecting tube, a central controller, a solenoid valve, an alarm and an electromagnetic flowmeter. Aging detection is performed on the laser group to be detected, including laser 1, laser 2, laser 3, ..., laser N. The light collecting tube and the laser controller appear in a group. Any group of light collecting tubes and laser controllers corresponds to a laser to be tested, and the output results of each laser controller are processed by the central controller. When there are abnormal data in the aging detection results, an alarm is issued through the alarm. In addition, since a large amount of heat is generated during the operation of the laser, the output of the laser is collected by the light collecting tube and cooled by the cooling water flowing through the light collecting tube to avoid damage to the equipment.

[0024] Based on this, a laser group to be tested, which includes multiple lasers, is placed at the corresponding test position. A pressure switch is arranged at the test position. When the aging command is received, when the laser is placed on the pressure switch, a pressure signal is triggered. Corresponding to the pressure signal, the solenoid valve opens. Figure 2 As shown, cooling water starts to flow through water channel 1 and water channel 2 and circulates in the light collecting tube; the light collecting tube is used to collect the laser power output by the laser and convert it into heat. The built-in circulating water takes away the heat, and the laser controller detects the temperature of the light collecting tube through NTC.

[0025] When the cooling water starts to circulate, the laser group to be tested is connected, and the first cooling state is obtained according to the flow of cooling water. It should be noted that the flow of cooling water is detected by an electromagnetic flowmeter. Then, the output data of each laser in the laser group to be tested is determined through the external interface of each laser in the laser group to be tested, the second aging state is determined, and the internal data of each laser in the laser group to be tested that is not output to the outside, that is, the state data, is called to determine the third aging state. When the aging time reaches the standard, that is, after the preset time period, the aging detection stops, and each data is uploaded, that is, the detection result is uploaded.

[0026] Furthermore, in step S102, the process of receiving the pressure signal of the pressure switch triggered by the laser group to be detected is specifically implemented as follows in this embodiment: Arrange all the lasers to be detected in the laser group to be detected at the corresponding pressure switch positions; determine the triggering conditions of all the pressure switches, generate a first alarm signal when any of the pressure switches is not triggered, and generate a pressure signal when all the pressure switches are triggered.

[0027] Among them, Figure 3 As shown in the laser controller workflow diagram of a laser aging detection method provided, the piezoelectric switch detection is judged. When all the pressure switches are triggered, a command response 2 is generated, that is, a pressure signal is generated. When any of the pressure switches is not triggered, a command response 1 is generated, that is, a first alarm signal.

[0028] It should be noted that Figure 3 The aging command instructs the aging detection process of the laser group to be detected to start executing, and the execution order of the aging command can be before receiving the pressure signal of the pressure switch triggered by the laser group to be detected, or after receiving the pressure signal of the pressure switch triggered by the laser group to be detected. The specific execution process is determined by the actual usage needs of the user and does not affect the final aging detection effect. This embodiment does not limit it.

[0029] Furthermore, in step S102, in response to the pressure signal, the solenoid valve is opened to circulate the cooling water in the light collecting cylinder. In this embodiment, the specific implementation method is as follows: In response to the pressure signal, the electromagnetic valve is opened to circulate the cooling water built into the light collecting cylinder, and a preset electromagnetic flowmeter is opened to monitor the flow of the cooling water.

[0030] First, the central controller has a built-in touch display, RS485 interface, 0 / 24V output interface, and 4G communication module. Specifically, the central controller establishes communication with the laser and electromagnetic flowmeter through the RS485 bus, sends aging commands to the laser controller, queries the laser and electromagnetic flowmeter data in real time, sends instructions to stop aging when the data is abnormal, drives the alarm through the 0 / 24V output interface, and sends alarm text messages through the built-in 4G communication module. The central controller touch screen interface includes the aging process setting interface, real-time data display interface, alarm log display interface, aging progress, and result display interface.

[0031] Among them, Figure 4 As shown in the workflow diagram of the central controller of a laser aging detection method provided, first, the 4G communication module is initialized, that is, the last detection data is cleared to prevent data confusion. Subsequently, the start test button of the touch screen is pressed, which can be understood as generating an aging command. Then the solenoid valve is opened, and the electromagnetic flowmeter data is read. When the cooling water flow rate meets the requirements, an aging instruction is sent to the target laser controller. The aging instruction here is different from the aging command. The aging instruction here can be understood as, in step S104, an instruction to connect the laser group to be detected.

[0032] In addition, if Figure 4 As shown in the central controller workflow diagram of a laser aging detection method provided, the process of monitoring the flow rate of cooling water can be understood as a step to determine whether the cooling water flow rate meets the requirements. If so, the subsequent process is executed. If not, the touch screen displays an abnormality.

[0033] Furthermore, the laser group to be detected is turned on in step S104. Figure 3 In a laser controller workflow diagram of a laser aging detection method provided, for a single laser in a laser group to be detected, the laser is powered on, the laser main power is turned on, and communication is established with the laser.

[0034] Furthermore, in step S104, the process of determining the first aging state according to the flow rate of cooling water is specifically implemented as follows in this embodiment: The flow data of the electromagnetic flowmeter is read. If the flow data is normal, the first aging state is normal; if the flow data is abnormal, the first aging state is abnormal, the laser group to be detected is turned off, the electromagnetic valve is closed, and a second alarm message is generated.

[0035] Among them, Figure 4As shown in the work flow diagram of the central controller of a laser aging detection method provided, after the electromagnetic flowmeter data is read, the data is judged to be abnormal. If there is data abnormality, the alarm is driven, an alarm text message is sent, the abnormal display is touched, a broadcast instruction is issued, all lasers stop aging, and the solenoid valve is closed. That is, the first aging state is abnormal, and all equipment for laser aging detection needs to be shut down, and a second alarm instruction is generated; if there is no data abnormality, the electromagnetic flowmeter data reading continues, and the first aging state is normal at this time.

[0036] Based on this, since the data read by the electromagnetic flowmeter is the data of cooling water, and the abnormal circulation of cooling water will not only affect the aging detection of all lasers, but also if the cooling water is abnormal, it will cause problems in the heat dissipation during the aging process of the laser, and then heat accumulation will occur, causing damage to all lasers. Therefore, it is necessary to shut down the laser group to be tested, close the solenoid valve, and notify relevant personnel for maintenance.

[0037] Furthermore, in step S106, the process of determining the second aging state of the laser group to be detected through the external interface of the laser group to be detected is specifically implemented as follows in this embodiment: The external output signals of all the lasers to be detected in the laser group to be detected are determined through the external interface of the laser group to be detected; when the external output signals are abnormal, the lasers to be detected in the laser group to be detected corresponding to the abnormal external output signals are turned off; and the second aging state is generated according to the turn-off status of all the lasers to be detected.

[0038] First, the laser controller has a built-in network port, RS48 interface, analog & digital signal input and output interface, and NTC temperature measurement interface. It receives instructions from the central controller and provides various signals required for laser control according to logic. During the aging process, it queries the real-time data of the laser through the network port, queries the NTC temperature data in real time, terminates aging when the data is abnormal, and counts the aging time. After the time is up, it stops the laser aging and automatically detects the laser function interface.

[0039] Among them, Figure 3 As shown in the laser controller workflow diagram of the provided laser aging detection method, for one laser in the laser group to be detected, it is determined that the laser status query feedback signal is abnormal. If so, the aging is stopped and the abnormality is reported, which can be understood as detecting the external output signal of the laser; when the external output signal is abnormal, the laser to be detected in the laser group to be detected corresponding to the abnormal external output signal is turned off, and a second aging state is generated according to the shutdown result.

[0040] Furthermore, in step S108, the state data inside the laser group to be detected is called, and the process of determining the third aging state according to the state data is specifically implemented as follows in this embodiment: The status data of all the detectors to be detected in the laser group to be detected are called; when the status data is abnormal, the laser to be detected in the laser group to be detected corresponding to the abnormal status data is turned off; and a third aging state is generated according to the turn-off status of all the lasers to be detected.

[0041] Among them, Figure 3 As shown in the laser controller workflow diagram of a laser aging detection method provided, for a laser in the laser group to be detected, the communication instruction reads the laser data and determines whether the data is abnormal. If there is no abnormality, the reading continues. If there is an abnormality, the aging is stopped and the abnormality is reported. It can be understood as calling the status data to determine whether there is an abnormality in the status data. If so, the laser to be detected corresponding to the abnormal status data in the laser group to be detected is turned off, and the third aging state is generated according to the shutdown result.

[0042] For the second aging state and the third aging state, the laser controller reports to the central controller, such as Figure 4 As shown in the central controller workflow diagram of a laser aging detection method provided, the laser controller data is queried. If there is no abnormality in the data, the query continues. If there is an abnormality, the alarm is driven, an alarm text message is sent, and an abnormality prompt is displayed when touching.

[0043] Furthermore, in step S110, after a preset time period, the aging detection stops, and the process of uploading the detection result is specifically implemented as follows in this embodiment: After starting the aging timer until the preset time period, the laser group to be detected is turned off, and the interface functions of all lasers to be detected in the laser group to be detected are detected, and the detection results are generated and uploaded according to the interface function detection results, the second aging state and the third aging state.

[0044] Among them, Figure 3 As shown in the laser controller workflow diagram of a laser aging detection method provided, for a laser in the laser group to be detected, the aging time is counted and reported until the aging time is over. After the aging is over, the laser stops outputting, the functions of the laser interfaces are tested, and the test results are reported. For the laser group to be detected, such as Figure 4 The central controller workflow diagram of the provided laser aging detection method is shown as follows: until all aging is completed, the touch screen display is updated, a text message is sent, and the electromagnetic is turned off.

[0045] In addition, it should be noted that in the specific implementation process, the existing laser controller hardware configuration uses 24V power input, which is converted to 5V by power isolation module 1, and 5V is converted to 3.3V by LDO1 to power the main control chip. 24V is converted to 5V by power module 1, and 12V is used to power the external interface related circuits.

The output signal of the isolation amplifier is amplified to 0-10V output by operational amplifier 1. The analog signal is collected by dividing the analog voltage signal by resistors and then electrically isolated by isolation amplifier 2. The output signal of the isolation amplifier is connected to the AD pin of the STM32F107ZET6 microcontroller for signal collection. The digital signal output is connected to the base of the NPN transistor through the digital output pin level of the STM32F107ZET6 microcontroller, and the collector is connected to the relay coil. One end of the relay switch contact is connected to 24V to realize the conversion of the 0 / 3.3V level of the microcontroller to 0 / 24 V level and electrical isolation, the digital signal input is connected to the optocoupler emitter after the 0 / 24V level signal is divided by a resistor, and the optocoupler collector resistor is pulled up to 3.3v and connected to the STM32F107ZET6 microcontroller digital input pin to complete the 0 / 24V level detection, and the input signal is electrically isolated from the microcontroller system; RS232 interface: the microcontroller STM32F107ZET6 serial port 1 is connected to the input end of the communication isolation chip 1, and the output end of the communication isolation chip 1 is connected to the RS232 conversion chip 1, so as to realize the external RS232 communication signal and the microcontroller Communication and system electrical isolation; RS485 interface: MCU STM32F107ZET6 serial port 2 is connected to the input end of communication isolation chip 2, and the output end of communication isolation chip 2 is connected to RS485 conversion chip 1, so as to realize the communication between external RS485 communication signal and MCU and the electrical isolation of the system; NTC temperature detection: 5V is connected in series with 10K resistor and then connected to NCT thermistor to convert the resistance signal into voltage signal. The voltage signal is impedance isolated by transport amplifier 2 and then connected to the AD pin of STM32F107ZET6 MCU for signal acquisition.

[0046] For the central controller hardware, a 24V power input is used, which is converted to 5V by power isolation module 1, and 5V is converted to 3.3V by LDO1 to power the main control chip, and 5V is converted to 4.2V by LDO2 to power the 4G communication module; the core architecture of the detection host is STM32F103RCT6+SIM7600C1, and the digital signal output is connected to the base of the NPN transistor through the digital output pin level of the STM32F103RCT6 microcontroller, and the collector is connected to the relay coil. One end of the relay switch contact is rooted to 24V, so that the 0 / 3.3V level of the microcontroller is converted to the 0 / 24V level and electrically isolated; the touch screen is powered by 24V and communicates with the RS232 interface. The serial port 1 of the microcontroller STM32F103RCT6 is connected to the input end of the communication isolation chip 3, and the output end of the communication isolation chip 3 is connected to the RS232 conversion chip 2, so that the RS232 communication signal of the touch screen communicates with the microcontroller and the system is electrically isolated; 4G communication is achieved through the microcontroller STM32F103RCT6 Serial port 2, digital IO communication is connected to the corresponding pins of the 4G communication module.
