Figure 4 This is a structural block diagram of a laser control and monitoring device provided in an embodiment of the present application. The utility model provides a laser control and monitoring device, comprising a housing, a laser signal generating unit 1, a main control unit 2, an interface unit 3, and a display unit 4.

[0063] Specifically, the laser control and monitoring device also includes a driving unit 5, an indicating unit 6, a temperature collection unit 7, a power switch, and a power indicator light. The driving unit 5 is connected to the main control unit 2 for receiving and driving the output signal of the main control unit 2; the indicating unit 6 is connected to the driving unit 5 for indicating the light output status of the laser and whether the fan and buzzer are working according to the output signal after driving; the temperature collection unit 7 is connected to the main control unit 2 for collecting the ambient temperature; the power switch is communicatively connected to the main control unit 2 for turning on the laser control and monitoring device; the power indicator light is communicatively connected to the main control unit 2 for displaying whether the laser control and monitoring device is turned on or off.

[0064] Specifically, the temperature acquisition unit 7 consists of a high-precision reference voltage source and an amplifier. This is a high-precision, low-noise circuit. The temperature sensor generates a weak signal, so this circuit is needed to amplify it with high precision for processing by the main control unit, thereby achieving accurate temperature measurement.

[0065] Specifically, the laser signal generating unit 1 includes a rotary encoder and an anti-interference circuit, the rotary encoder is used to generate a laser pulse signal; the input end of the anti-interference circuit is connected to the output end of the rotary encoder, the output end of the anti-interference circuit is connected to the main control unit 2, and the anti-interference circuit is used to receive and remove interference signals in the laser pulse signal.

[0068] Specifically, the indicator unit 6 includes a fan, a buzzer, an indicator light, and a mute light, and the fan, buzzer, indicator light, and mute light are all connected to the drive unit 5. The anti-interference circuit includes a Schmitt trigger. The drive unit 5 includes a Darlington transistor.

[0069] In one embodiment of the present invention, the anti-interference circuit is composed of a Schmitt trigger. The rotary encoder may generate irregular waveform signals due to mechanical rotation. The anti-interference circuit can suppress noise and convert the irregular waveform into a regular square wave model, which is convenient for subsequent main control circuit to process it and improves the stability of the circuit.

[0070] The driving unit 5 is composed of Darlington transistors. The interface driving capability of the main control unit 2 is weak. The purpose of adding this circuit is to enhance the driving capability and drive the fan, buzzer, light status indicator, etc.

[0071] In one embodiment of the present utility model, the laser control and monitoring device adopts a portable structure, mainly including a laser signal generating unit 1, a main control unit 2, an interface unit 3, a display unit 4, a drive unit 5, an indication unit 6, and a temperature acquisition unit 7. The main control unit 2 and the interface unit 3 are both arranged inside the shell, and the laser signal generating unit (1) and the display unit 4 are both arranged on the surface of the shell.

[0073] The main control unit 2 has an interface: different power requirements are sent to the main control unit 2 via a rotary encoder. The power requirements can be visually displayed on the digital tube display, allowing rapid adjustment to the required power value. The main control unit 2 transmits the power requirements to each laser module via the CAN bus, which then emits lasers of the corresponding power. The LCD screen also displays the status of each laser module and the data that needs to be monitored.

[0074] This device is equipped with a laser control and monitoring device to monitor and manage the laser module, monitor the status and parameters of the laser module in real time, and issue an alarm in time when problems are found.

[0075] Please continue reading Figures 1 to 4 The present invention provides a laser control and monitoring device equipped with a health monitoring system to monitor and manage the laser module. The specific implementation is as follows:

[0076] 1. Power on self-test

[0077] After the main control unit 2 is powered on, it first sends a status query command to each laser module. This command is used to query the status information of each laser module. If one or more channels do not respond, the query command is sent again after 1 second. The fault tolerance for lasers that do not respond is 3 times. If the laser does not respond 3 times, the laser module is considered to be faulty and needs to be displayed on the digital tube display and a synchronous alarm sound is sounded.

[0078] After powering on, the main control unit 2 monitors the DC12V voltage status of the power supply in real time. If the voltage is unstable or the ripple is excessive, the fault will be displayed on the digital tube display and an alarm will sound simultaneously. The normal voltage range is [11.5, 12.5] V. Voltages outside this range are alarm voltages.

[0079] 2. Digital tube display

[0080] The digital tube is 4-digit and includes the following display modes:

[0081] a) Power display mode

[0082] This state is the normal display mode, which sends different optical power requirements to the main control unit 2 through the rotary encoder, and the digital tube displays the 4-digit laser optical power requirement.

[0083] b) DC power supply voltage fault display mode

[0084] When the main control unit 2 detects that the DC12V voltage is unstable, a fault prompt is required at the digital tube. The fault code begins with AA. The specific fault prompt information content and meaning are shown in Table 1.

[0085] There are two criteria for determining power supply voltage failure:

[0086] 1) The voltage is higher than 12.5V;

[0087] 2) The voltage is lower than 11.5V.

[0088] c) Laser module communication fault display mode

[0089] When a communication failure occurs in a certain laser module, a fault prompt is required on the digital tube. The fault code starts with CC. The specific fault prompt content and meaning are shown in Table 1.

[0090] There are two criteria for communication failure:

[0091] 1) After the main control unit 2 is turned on, it sends status query commands three times in succession but does not receive a response from the laser;

[0092] 2) After the status query is passed, the laser module fails to report status information for three consecutive times (within 3 seconds);

[0093] d) Laser module output power fault display mode

[0094] When a laser fails to emit light, a fault prompt is required on the digital tube. The fault code starts with EE. The specific fault prompt content and meaning are shown in Table 1.

[0095] The criterion for laser light failure is: the power value fed back by the laser module differs from the required value by more than 20%.

[0096] e) Laser module temperature over-limit fault display mode

[0097] When the temperature of a certain laser exceeds the limit, a fault prompt is required at the digital tube. The fault code starts with FF. The specific fault prompt content and meaning are shown in Table 1.

[0098] The criterion for laser light failure is: the laser module die temperature value deviates from 25°C by more than 10°C.

[0099] f) Laser module LD current fault display mode

[0100] When the LD current of a certain laser exceeds the limit, a fault prompt is required at the digital tube. The fault code begins with EF. The specific fault prompt content and meaning are shown in Table 1.

[0101] The criterion for laser light failure is: LD current exceeds 1.8A.

[0102] g) Laser TEC current fault display mode

[0103] When the TEC current of a certain laser exceeds the limit, a fault prompt is required at the digital tube. The fault code begins with EF. The specific fault prompt content and meaning are shown in Table 1.

[0104] The criterion for laser TEC current failure is: TEC current exceeds 2.25A.

[0105] h) Cycle display mode

[0106] When a fault occurs in the laser control box, the digital tube should alternately display the required laser power value and the fault code, with an alternating cycle of 1s.

[0107] When there is more than one fault code, all fault code contents should be displayed alternately, arranged in sequence according to the sequence in Table 1, and the alternation cycle is 1s.

[0108] Table 1 Digital tube display content

[0109]

[0110]

[0111] 3.Light control

[0112] The housing features a "laser on / off" button. After receiving this button information, the main control unit 2 transmits a CAN bus command, first checking and waiting for the laser die temperature to be within the operating range (15, 35°C) before sending the laser on / off signal to the laser module. If the laser die temperature does not reach the operating range within 1 minute after receiving the laser on command, the laser is directly turned on. A digital display indicates that the laser temperature has exceeded the limit.

[0113] 4. Laser power adjustment

[0114] The housing is equipped with a "power adjustment" knob, which is in the form of an encoder. After powering on, the default setting is the last power value (effective when powered off). The main control unit 2 obtains the button information and sends the output power requirement to the laser module via the CAN bus command.

[0115] 5. Light status indication

[0116] The indicator light has three states, each with different meanings, as follows:

[0117] a) Extinguish

[0118] External operation controls the laser to shut down.

[0119] b) Flashing (period 1s)

[0120] The laser was turned on by external operation control, but not all laser die temperatures could be controlled within the range of [15,35]°C, and no turn-on command was issued to the laser.

[0121] c) Constant light

[0122] The external operation control turns on the laser and the light control command has been sent to the laser.

[0123] 6.Buzzer

[0124] When a fault such as 12V power supply failure, laser communication failure, laser core temperature exceeding the limit, laser output power failure, laser LD current exceeding the limit, or laser TEC current exceeding the limit occurs, the beeping and flashing prompt will be given. The beeping will stop after being muted, and it will beep again when a new fault occurs.

[0125] 7. Noise reduction

[0126] The mute button is non-self-locking. When the buzzer alarm sounds, press it once to mute the alarm.

[0127] If you press the mute button twice in 1 second (double-click), it will enter the "silent" mode. The yellow indicator light in the mute button will light up. At this time, no matter what fault status occurs, the buzzer will no longer beep or flash.

[0128] 8. Fan

[0129] The main control unit 2 can drive and control the DC fan to adjust the laser heat dissipation environment temperature. There are two ways to control it:

[0130] a) The temperature detected by the temperature sensor is lower than the ideal temperature of the laser die, and the fan does not work.

[0131] b) The temperature detected by the temperature sensor is higher than the ideal temperature of the laser die. The larger the temperature difference, the faster the fan speed will be. However, when the temperature difference is greater than 10 degrees Celsius, the fan will work at full speed.

[0132] 9. LCD screen

[0133] The LCD screen is a touch screen. The main page and sub-page display effects of the LCD screen are as follows Figure 5 and Figure 6 The main page displays the status of multiple laser modules, including operating status, communication status, optical power, die temperature, LD current, and TEC current. Red indicates abnormal data, and gray indicates no data. The secondary page displays the temperature detected by the temperature sensor and fan status. You can switch between the two pages using the "Next Page" and "Previous Page" buttons in the lower right corner.

[0134] In summary, the laser control and monitoring device of this utility model includes a housing, a laser signal generation unit, a main control unit, an interface unit, and a display unit. This portable device houses multiple laser modules with adjustable power, and the laser power adjustment has a power-off memory function. This device is equipped with a health monitoring system that monitors the laser modules in real time, providing prompt alarms when faults occur, facilitating location and repair, and greatly facilitating research personnel.
