During current debugging, testing, and experimentation, various performance parameters and functional indicators, including output voltage, initial and final self-test, input voltage polarity indication, and xenon lamp triggering, must be tested.

The initial and final self-test verifies the self-test data of the laser power supply counter box's counter board (including the first target 075 and the last target 975). The voltage polarity indication indicates the laser power supply counter box's +26V input voltage reverse polarity protection function.

[0025] [Example 1]

[0026] like Figure 1 As shown, a detection device for a laser power supply counter box includes:

[0027] A power supply voltage module unit, connected to an external power supply to supply power to other units;

[0028] like Figure 2 As shown, the power supply voltage module unit supplies power to the remaining units of the detection device. Specifically,

[0029] The supply voltage module unit includes a switching switch and an AC / DC power supply module. The AC / DC power supply module is connected to an external mains power supply and is used to convert AC mains power into DC power. The switching switch is also electrically connected to the external DC power supply and the AC / DC power supply module. The switching switch switches to directly conduction or conduction after conversion by the AC / DC power supply module according to the type of external power supply.

[0030] When there is a +26V DC power supply, switch to the DC power supply circuit through the switch and be powered by an external DC power supply;

[0031] In the absence of a DC power supply, use 220V AC power from the mains and switch the switch to the AC power supply circuit. The AC power is converted to +26V DC power by the AC / DC power module MV-S-350-27 and then output to power other units.

[0032] Specific circuits such as Figure 2 As shown, it includes two double-pole double-throw switches, one for switching between AC and DC, and the other for controlling the start-up switch. The start switch and the switch are both arranged on the front panel of the detection device.

[0033] like Figure 2 As shown, the two input terminals of the double-pole double-throw switch are terminals 1 and 2, 34 is one group of output terminals, and 56 is another group of output terminals.

[0034] Connect one mains output to the AC power supply via one input of the AC / DC power module. Connect the other output to a 3A resistor, a toggle switch, and a start switch, before finally connecting to the other input of the AC / DC power module. The AC / DC power module output is then connected to the input of the input voltage forward and reverse polarity indicator.

[0035] The positive pole of the +26V DC power supply is connected to the switch and the start switch in sequence, and finally connected to the positive input terminal of the subsequent input voltage positive and reverse polarity indication unit, and the negative pole is directly connected to the negative input terminal of the input voltage positive and reverse polarity indication unit.

[0036] Connect the 3A fuse to terminal 1 of the transfer switch, connect terminal 3 of the transfer switch to terminal 1 of the start switch, and connect terminal 3 of the start switch to the AC / DC power module.

[0037] The positive pole of the +26V DC power supply is connected to the 2nd terminal of the switching switch, the 6th terminal of the switching switch is connected to the 2nd terminal of the starting switch, and the 6th terminal of the starting switch is connected to the positive input terminal of the input voltage positive and reverse polarity indication unit.

[0038] The 4 and 5 terminals of the transfer switch and the start switch are disconnected. For example, when AC power is input, 1 and 3 are connected to conduct the AC power, and 2 and 4 are connected. Since the 4 terminal is disconnected, the DC power is not passed, thus achieving DC-AC switching. The same applies to the start switch.

[0039] like Figure 5 As shown, it also includes an input voltage positive and negative connection indication unit, including a positive and negative selection switch, a time delay relay, a positive indication diode and a reverse indication diode. The input end of the power supply voltage module unit is connected to the positive and negative selection switch power supply voltage module unit, and the output end of the positive and negative selection switch is respectively connected to the 4th, 14th and 13th pins of the time delay relay. The positive and negative ends of the positive indication diode are respectively connected to the 12th and 9th pins of the time delay relay, and the positive and negative ends of the reverse indication diode are respectively connected to the 9th and 12th pins of the time delay relay.

[0040] The input voltage positive and negative connection indicating unit detects the positive and negative connection input voltage of the laser power supply counter box to determine whether the laser power supply counter box has a reverse connection protection function after the input voltage is reversed.

[0041] The forward and reverse selection switch is the same as the transfer switch, both of which are double-pole double-throw switches.

[0042] Terminal 1 of the forward / reverse selection switch is connected to the positive output terminal of the power supply voltage module unit, and terminal 2 is connected to the negative output terminal.

[0043] Terminal 3 is connected to pin 4 of the time delay relay, terminal 4 is connected to pin 13 of the time delay relay, terminal 5 is connected to pin 14 of the time delay relay, and terminal 6 is connected to pin 13 of the time delay relay.

[0044] Connect pin 12 of the time delay relay to the positive terminal of the positive indicating diode, and pin 9 to the negative terminal;

[0045] The 12th pin of the time delay relay is connected to the negative terminal of the reverse indicator diode, and the 9th pin is connected to the positive terminal. When the positive and negative selection switches 1 and 3 are connected, and 2 and 4 are connected, the 4th pin of the time delay relay receives a high level signal, the 12th pin outputs a high level, and the 9th pin remains low, and the positive indicator diode is turned on and emits light (i.e. Figure 7 (in the positive direction indication), indicating that it is in the positive connection state;

[0046] When the forward and reverse selection switches 1 and 5 are connected, and 2 and 6 are connected, the delay relay 14 pin receives a high level signal, the 12 pin remains low, the 9 pin outputs a high level, and the reverse indicator diode is turned on and emits light (i.e. Figure 7 Reverse indication in the middle), indicating that it is in reverse connection state.

[0047] like Figure 3 As shown, the output voltage selection and display unit includes a dip switch and a digital voltmeter. The output end of the dip switch is connected to the digital voltmeter ( Figure 7 The input end of the DIP switch is electrically connected to the voltage output end of the laser power supply counter box through a cable, and the other end of the DIP switch is grounded;

[0048] The laser power counter box outputs include +5V, +6V, -6V, +26V and high voltage output GY as the xenon lamp power supply.

[0049] The output voltage selection and display unit also includes a voltage divider, and the laser power counter box also includes a xenon lamp high voltage output end. The voltage divider is connected to the xenon lamp high voltage output end through a cable, and the other end of the voltage divider is connected to a digital voltmeter.

[0050] The output of the laser power supply counter box is connected to the detection device through a cable. The voltage of each channel is selected by the dip switch and the output voltage is displayed by the digital voltmeter XL5135V-4. Since the high voltage of the xenon lamp exceeds the test range of the voltmeter, it needs to be converted by a voltage divider before being displayed.

[0051] The output of the laser power supply counter box includes +5V, +6V, -6V, and +26V output terminals, which can be directly connected to the DIP switch through a cable for detection;

[0052] The high-voltage output end of the xenon lamp of the laser power supply counter box needs to be connected to a voltage divider for voltage division first. One end of the dip switch is connected to the voltage divider. The voltage divider and the digital voltmeter are connected in series for voltage division. The voltage divider is connected to the digital voltmeter, and pins 2 and 8 are grounded.

[0053] like Figure 4 As shown, the first and last self-test display unit includes a processor and a display screen ( Figure 7The processor is electrically connected to the laser power counter box to receive the self-test data output by the laser power counter box and transmit the self-test data to the display screen for display;

[0054] After the detection device's first and last switches, self-test switch, and KK switch are triggered, the laser power supply counter box counter board self-test data is decoded, driven, and latched by the processor, i.e., the integrated circuit MC14511, and then output by LED1, LED2, and LED3. Finally, the self-test data (first target 075, last target 975) is displayed to determine whether the counter board functions normally.

[0055] The start and end switches, self-test switch and trigger switch are all connected to the laser power counter box through cables. Switch the start and end to perform self-test. The high-voltage output function of the trigger counter box is all provided by the laser power counter box itself. The detection device only has switches for triggering and adjustment. The function of the laser power counter box itself is started by the switch, and then the data output by the laser power counter box is read and displayed on the LED.

[0056] like Figure 6 As shown, the xenon lamp trigger lighting unit includes a first trigger coil, a second trigger coil, an inductor coil connected in series and a xenon lamp. The input end of the inductor coil is connected to the xenon lamp power supply, i.e., a voltage divider, the negative pole of the xenon lamp is grounded, the positive pole of the first trigger coil is connected to the positive pole of the xenon lamp, and the negative pole is grounded. The positive pole of the second trigger coil is connected to the xenon lamp trigger switch, and the negative pole is grounded.

[0057] The xenon lamp triggering and lighting unit further includes a discharge switch, one end of the discharge switch is connected to the xenon lamp power supply, and the other end is grounded.

[0058] The xenon lamp trigger and lighting unit consists of a xenon lamp, a trigger coil, and an inductor. When the trigger switch is operated, a pulsed high voltage is output from the laser power supply counter box, which powers the xenon lamp through the inductor, and then the trigger coil illuminates the xenon lamp. Verify that the product has a pulsed high voltage and can illuminate the xenon lamp.

[0059] The power supply for the xenon lamp in the figure is provided by the laser power counter box, and the xenon lamp is lit through the trigger switch and two trigger coils.

[0060] Specifically, one end of the inductor coil is connected to a xenon lamp power supply, and the other end is connected to the xenon lamp, and the other end of the xenon lamp is grounded.

[0061] One end of the first trigger coil is connected to the xenon lamp, and the other end is grounded; one end of the second trigger coil is connected to the xenon lamp trigger, that is, the trigger switch KK. When the trigger switch is pressed, the second trigger coil is grounded and discharged, and a voltage difference is generated between the two trigger coils, thereby lighting the xenon lamp.

[0062] like Figure 8 and Figure 9As shown, test cable I connects the laser power counter box with the self-test data, normal voltage and function switch of the detection device; test cable II connects the laser power counter box with the xenon lamp voltage, xenon lamp trigger and ground terminal of the detection device.
