[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0032] Combine the following Figures 1 to 6 The spectral chip and electronic device of the present application are described.

[0033] According to the embodiment of the first aspect of the present application, Figure 1 and Figure 2 The spectral chip includes a photoelectric conversion module 1, a comparator module 2 and a controller 3.

[0034] The input end of the comparator module 2 is electrically connected to the photoelectric conversion module 1; the comparator module 2 includes a zero-crossing comparator 21 and an undervoltage comparator 22 and / or an undercurrent comparator 24 connected in parallel, the input end of the zero-crossing comparator 21 is electrically connected to the photoelectric conversion module 1, the input end of the undervoltage comparator 22 is electrically connected to the photoelectric conversion module 1, and the input end of the undercurrent comparator 24 is electrically connected to the photoelectric conversion module 1.

[0035] Output ends of the zero-crossing comparator 21 , the undervoltage comparator 22 , and the undercurrent comparator 24 are all electrically connected to the controller 3 .

[0036] Among them, the zero-crossing comparator 21 is used to output a signal to the controller 3 according to the comparison result between the voltage of the photoelectric conversion module 1 and the first preset voltage or the comparison result between the current of the photoelectric conversion module 1 and the first preset current, the undervoltage comparator 22 is used to output a signal to the controller 3 according to the comparison result between the voltage of the photoelectric conversion module 1 and the second preset voltage, and the undercurrent comparator 24 is used to output a signal to the controller 3 according to the comparison result between the current of the photoelectric conversion module 1 and the second preset current.

[0037] The controller 3 is electrically connected to the photoelectric conversion module 1 , and is configured to: control the photoelectric conversion module 1 according to the output signals of the zero-crossing comparator 21 and the undervoltage comparator 22 , or control the photoelectric conversion module 1 according to the output signals of the zero-crossing comparator 21 and the undercurrent comparator 24 .

[0038] According to the spectrum chip of the present application, the comparator module 2 and the photoelectric conversion module 1 are electrically connected together, so that the comparator module 2 can output a corresponding signal according to the comparison between the voltage or current of the photoelectric conversion module 1 and the preset value. When the spectrum chip is a voltage-type spectrum chip, the zero-crossing comparator 21 will compare the voltage of the photoelectric conversion module 1 with the first preset voltage, and the undervoltage comparator 22 will compare the voltage of the photoelectric conversion module 1 with the second preset voltage. The zero-crossing comparator 21 and the undervoltage comparator 22 will both output signals to the controller 3 according to the comparison results. The controller 3 can determine whether the voltage of the photoelectric conversion module 1 is equal to the first preset voltage according to the output signal of the zero-crossing comparator 21, and whether the voltage of the photoelectric conversion module 1 is equal to the second preset voltage according to the output signal of the undervoltage comparator 22. When it is determined that the voltage of the photoelectric conversion module 1 is first equal to the first preset voltage and then drops from the first preset voltage to the second preset voltage, it means that the spectrum chip may be irradiated by a high-power laser pulse or other high-power light at this time, and the voltage generated by the spectrum chip later may be too large, then the controller 3 will control the photoelectric conversion module 1 to stop working to avoid damage to the spectrum chip. When the spectral chip is a current-type spectral chip, the zero-crossing comparator 21 will compare the current of the photoelectric conversion module 1 with the first preset current, and the undercurrent comparator 24 will compare the current of the photoelectric conversion module 1 with the second preset current. The zero-crossing comparator 21 and the undercurrent comparator 24 will both output signals to the controller 3 based on the comparison results. The controller 3 can determine whether the current of the photoelectric conversion module 1 is equal to the first preset current based on the output signal of the zero-crossing comparator 21, and can determine whether the current of the photoelectric conversion module 1 is equal to the second preset current based on the output signal of the undercurrent comparator 24. When it is determined that the current of the photoelectric conversion module 1 is first equal to the first preset current and then drops from the first preset current to the second preset current, it means that the spectral chip may be irradiated by a high-power laser pulse or other high-power light at this time, and the current generated by the spectral chip subsequently may be too large, then the controller 3 will control the photoelectric conversion module 1 to stop working to avoid damage to the spectral chip. That is, the present application detects the voltage of the photoelectric conversion module 1 through the comparator module 2, and promptly determines whether the spectral chip is irradiated by a high-power laser pulse or other high-power light, so as to promptly shut down the photoelectric conversion module 1, thereby adding a protection mechanism to the spectral chip. This can avoid damage to the spectral chip due to excessive voltage or current in the spectral chip, and effectively prevent the spectral chip from being burned and unable to work normally under extreme conditions such as excessive voltage or current.

[0039] It is understandable that if Figure 4When the voltage-type spectral chip is irradiated by a high-power laser pulse or other high-power light, the voltage of the photoelectric conversion module 1 will first pass through a zero voltage point V0, then the voltage will drop to the undervoltage voltage point V1, and then the voltage will quickly rise to the overvoltage voltage point V2. When the voltage exceeds the Vmax point which is higher than the overvoltage voltage point, it may cause temporary or permanent physical damage to the components of the spectral chip. Then, the voltage of the photoelectric conversion module 1 can be detected. When the voltage of the photoelectric conversion module 1 is successively reduced to the zero voltage point V0 (corresponding to the first preset voltage) and the undervoltage voltage point V1 (corresponding to the second preset voltage), it means that the spectral chip may be irradiated by a high-power laser pulse or other high-power light, and the photoelectric conversion module 1 needs to be controlled to stop working in time to avoid the voltage of the photoelectric conversion module 1 exceeding the Vmax point and causing temporary or permanent physical damage to the components of the spectral chip.

[0040] It is understandable that if Figure 5 When the current-type spectral chip is irradiated by a high-power laser pulse or other high-power light, the current of the photoelectric conversion module 1 will first pass through a zero current point I0, then the current will drop to the undercurrent current point I1, and then the current will quickly rise to the overcurrent current point I2. When the current exceeds the Imax point which is higher than the overcurrent current point, it may cause temporary or permanent physical damage to the components of the spectral chip. Then, the current of the photoelectric conversion module 1 can be detected. When the current of the photoelectric conversion module 1 is successively reduced to the zero current point I0 (corresponding to the first preset current) and the undercurrent current point I1 (corresponding to the second preset current), it means that the spectral chip may be irradiated by a high-power laser pulse or other high-power light, and the photoelectric conversion module 1 needs to be controlled to stop working in time to avoid the current of the photoelectric conversion module 1 exceeding the Vmax point and causing temporary or permanent physical damage to the components of the spectral chip.

[0041] It can be understood that the technical solution of the present application can effectively protect both voltage-type spectroscopy chips and current-type spectroscopy chips.

[0042] In one embodiment of the present application, Figure 2 The comparator module 2 includes an overvoltage comparator 23, an input end of the overvoltage comparator 23 is electrically connected to the photoelectric conversion module 1, and an output end of the overvoltage comparator 23 is electrically connected to the controller 3. The overvoltage comparator 23 is used to output a signal to the controller 3 according to the comparison result between the voltage of the photoelectric conversion module 1 and the third preset voltage. The controller 3 is configured to control the photoelectric conversion module 1 based on the output signal of the overvoltage comparator 23.

[0043] It can be understood that when the spectral chip is a voltage-type spectral chip, the overvoltage comparator 23 will compare the voltage of the photoelectric conversion module 1 with the third preset voltage, and output a signal to the controller 3 based on the comparison result. The controller 3 can determine whether the voltage of the photoelectric conversion module 1 is equal to the third preset voltage based on the output signal of the overvoltage comparator 23. When it is determined that the voltage of the photoelectric conversion module 1 is equal to the third preset voltage, it means that the voltage in the spectral chip is about to exceed the Vmax point, and then the controller 3 controls the photoelectric conversion module 1 to stop working to avoid the voltage in the spectral chip exceeding the Vmax point and causing damage to the spectral chip.

[0044] It is understandable that when the spectral chip is irradiated with a high-power laser pulse or other high-power light, the voltage of the photoelectric conversion module 1 will be reduced to the first preset voltage and the second preset voltage in turn, that is, the zero-crossing comparator 21 and the undervoltage comparator 22 will be triggered in turn, and the controller 3 will control the photoelectric conversion module 1 to stop working according to the output signals of the zero-crossing comparator 21 and the undervoltage comparator 22. If the controller 3 successfully controls the photoelectric conversion module 1 to stop working, the overvoltage comparator 23 will not be triggered again. If the controller 3 fails to successfully control the photoelectric conversion module 1 to stop working, the voltage of the photoelectric conversion module 1 will rise to the third preset voltage, thereby triggering the overvoltage comparator 23. At this time, the overvoltage comparator 23 will send an output signal to the controller 3, so that the controller 3 will control the photoelectric conversion module 1 to stop working again according to the output signal of the overvoltage comparator 23, thereby realizing double protection for the spectral chip, and effectively preventing the spectral chip from being damaged due to overvoltage.

[0045] It can be understood that the third preset voltage corresponds to the overvoltage point V2.

[0046] In an embodiment of the present application, the third preset voltage is greater than the first preset voltage, and the first preset voltage is greater than the second preset voltage.

[0047] It can be understood that the first preset voltage can be the zero voltage V0, or any voltage value between the zero voltage V0 and the undervoltage voltage V2. The second preset voltage can be the undervoltage voltage V2, or a voltage value greater than the undervoltage voltage V2, and it is sufficient to ensure that the first preset voltage is greater than the second preset voltage, so that the first preset voltage to the second preset voltage is a downward trend. The third preset voltage can be the overvoltage voltage V3, or any voltage value between the zero voltage V0 and Vmax.

[0048] In one embodiment of the present application, Figure 2The comparator module 2 includes an overcurrent comparator 25, an input end of the overcurrent comparator 25 is electrically connected to the photoelectric conversion module 1, and an output end of the overcurrent comparator 25 is electrically connected to the controller 3. The overcurrent comparator 25 is used to output a signal to the controller 3 according to the comparison result between the current of the photoelectric conversion module 1 and the third preset current. The controller 3 is configured to control the photoelectric conversion module 1 based on the output signal of the overcurrent comparator 25.

[0049] It can be understood that when the spectral chip is a current-type spectral chip, the overcurrent comparator 25 will compare the current of the photoelectric conversion module 1 with the third preset current, and output a signal to the controller 3 based on the comparison result. The controller 3 can determine whether the current of the photoelectric conversion module 1 is equal to the third preset current based on the output signal of the overcurrent comparator 25. When it is determined that the current of the photoelectric conversion module 1 is equal to the third preset current, it means that the current in the spectral chip is about to exceed the Imax point, and then the controller 3 controls the photoelectric conversion module 1 to stop working to avoid the current in the spectral chip exceeding the Imax point and causing damage to the spectral chip.

[0050] It is understandable that when the spectral chip is irradiated with a high-power laser pulse or other high-power light, the current of the photoelectric conversion module 1 will be reduced to the first preset current and the second preset current in sequence, that is, the zero-crossing comparator 21 and the undercurrent comparator 24 will be triggered in sequence, and the controller 3 will control the photoelectric conversion module 1 to stop working according to the output signals of the zero-crossing comparator 21 and the undercurrent comparator 24. If the controller 3 successfully controls the photoelectric conversion module 1 to stop working, the overcurrent comparator 25 will not be triggered again. If the controller 3 fails to successfully control the photoelectric conversion module 1 to stop working, the current of the photoelectric conversion module 1 will rise to the third preset current, thereby triggering the overcurrent comparator 25. At this time, the overcurrent comparator 25 will send an output signal to the controller 3, so that the controller 3 will control the photoelectric conversion module 1 to stop working again according to the output signal of the overcurrent comparator 25, thereby realizing double protection for the spectral chip, and effectively preventing the spectral chip from being damaged due to overcurrent.

[0051] Exemplarily, the third preset current corresponds to the overcurrent point I2.

[0052] In an embodiment of the present application, the third preset current is greater than the first preset current, and the first preset current is greater than the second preset current.

[0053] It can be understood that the first preset current can be the zero-point current I0, or any current value between the zero-point current I0 and the undercurrent current I2. The second preset current can be the undercurrent current I2, or a current value greater than the undercurrent current I2, and it is sufficient to ensure that the first preset current is greater than the second preset current, so that the first preset current to the second preset current is a downward trend. The third preset current can be the overcurrent current I3, or any current value between the zero-point current I0 and Imax.

[0054] In one embodiment of the present application, Figure 3 The spectral chip includes a spectral chip body and a temperature protection module 4. The temperature protection module 4 is connected to the spectral chip body. The temperature protection module 4 is electrically connected to the controller 3. The temperature protection module 4 is used to detect the temperature of the spectral chip body. The controller 3 is configured to control the operation of the photoelectric conversion module 1 based on the detection data of the temperature protection module 4.

[0055] It is understandable that the temperature protection module 4 will detect the temperature of the spectral chip body in real time and transmit the detection data to the controller 3, so that the controller 3 can determine whether the temperature of the spectral chip body exceeds the preset temperature. When it is determined that the temperature of the spectral chip body exceeds the preset temperature, it means that the spectral chip has abnormal conditions such as excessive voltage or excessive current. Then the controller 3 controls the photoelectric conversion module 1 to stop working to prevent the temperature of the spectral chip from continuing to rise and burning, which can effectively protect the spectral chip.

[0056] In the embodiments of the present application, Figure 3 The temperature protection module 4 includes a temperature sensor NTC, the temperature sensor NTC is abutted against the spectrum chip body, and the temperature sensor NTC is electrically connected to the controller 3.

[0057] It is understandable that the temperature of the spectral chip body is detected in real time by the temperature sensor NTC, so that the controller 3 can obtain the real-time temperature of the spectral chip body, so that the controller 3 can control the operation of the photoelectric conversion module 1 according to the temperature of the spectral chip body.

[0058] In the embodiments of the present application, Figure 3 The temperature protection module 4 includes a temperature comparator 41, the temperature sensor NTC is electrically connected to the input end of the temperature comparator 41, the output end of the temperature comparator 41 is electrically connected to the controller 3, the temperature comparator 41 is used to output a signal to the controller 3 according to the comparison result between the detection data of the temperature sensor NTC and the preset temperature, and the controller 3 is configured to control the operation of the photoelectric conversion module 1 based on the output signal of the temperature comparator 41.

[0059] It can be understood that the temperature comparator 41 will compare the detection data of the temperature sensor NTC with the preset temperature. Since the detection data of the temperature sensor NTC corresponds to the temperature data of the spectral chip body, that is, the temperature comparator 41 will compare the temperature of the spectral chip body with the preset temperature, and output a signal to the controller 3 according to the comparison result. The controller 3 can determine whether the temperature of the spectral chip body exceeds the preset temperature according to the output signal of the temperature comparator 41. When it is determined that the temperature of the spectral chip exceeds the preset temperature, the controller 3 controls the photoelectric conversion module 1 to stop working and reduce the voltage or current in the spectral chip to avoid the voltage or current in the spectral chip being too high and causing the spectral chip to burn out.

[0060] In one embodiment of the present application, Figure 3 The temperature protection module 4 includes a resistor R, one end of the resistor R is grounded, the other end of the resistor R is electrically connected to the negative input terminal of the temperature comparator 41, one end of the temperature sensor NTC is electrically connected to the positive electrode of the power supply, the other end of the temperature sensor NTC is electrically connected to the other end of the resistor R, and the positive input terminal of the temperature comparator 41 is electrically connected to the reference voltage Vref.

[0061] It is understandable that the resistance of the temperature sensor 41 will change with the temperature of the spectrum chip body. After the resistance of the temperature sensor 41 changes, the voltage at the negative input terminal of the temperature comparator 41 will also change. That is, the voltage at the negative input terminal of the temperature comparator 41 represents the temperature of the spectrum chip body. By comparing the voltage at the negative input terminal with the reference voltage, it can be determined whether the temperature of the spectrum chip body exceeds the preset temperature.

[0062] According to an embodiment of the second aspect of the present application, an electronic device includes the above-mentioned spectral chip.

[0063] According to the electronic device of the present application, the voltage of the photoelectric conversion module 1 is detected by the comparator module 2, so as to timely determine whether the spectral chip is irradiated by a high-power laser pulse or other high-power light, so as to timely shut down the photoelectric conversion module 1, thereby adding a protection mechanism to the spectral chip, which can avoid damage to the spectral chip caused by excessive voltage or current in the spectral chip, and effectively prevent the spectral chip from being burned and unable to work normally under extreme conditions such as excessive voltage or current.

[0064] According to an embodiment of the third aspect of the present application, Figure 6 , the spectrum chip control method includes:

[0065] Obtaining an input voltage or input current of the input photoelectric conversion module 1;

[0066] If the input voltage is less than the zero voltage and equal to the undervoltage voltage, or the input current is less than the zero current and equal to the undercurrent current, the photoelectric conversion module 1 is controlled to stop working, wherein the undervoltage voltage is less than the zero voltage.

[0067] According to the control method of the spectral chip of the present application, the controller 3 of the spectral chip obtains the input voltage of the photoelectric conversion module 1, and compares the input voltage of the photoelectric conversion module 1 with the zero-point voltage and the under-voltage voltage. When it is determined that the voltage of the photoelectric conversion module 1 is less than the zero-point voltage and equal to the under-voltage voltage, it means that the voltage change of the photoelectric conversion module 1 at this time is similar to or the same as the voltage change when the spectral chip is irradiated by a high-power laser pulse or other high-power light, indicating that the spectral chip may be irradiated by a high-power laser pulse or other high-power light at this time. The controller 3 controls the photoelectric conversion module 1 to stop working to avoid damage to the spectral chip due to excessive voltage or current in the spectral chip, effectively preventing the spectral chip from being burned and unable to work normally under extreme conditions such as excessive voltage or current. The controller 3 of the spectral chip obtains the input current of the photoelectric conversion module 1, and compares the input current of the photoelectric conversion module 1 with the zero-point current and the undercurrent current. When it is determined that the current of the photoelectric conversion module 1 is less than the zero-point current and equal to the undercurrent current, it means that the current change of the photoelectric conversion module 1 at this time is similar to or the same as the current change when the spectral chip is irradiated by a high-power laser pulse or other high-power light, indicating that the spectral chip may be irradiated by a high-power laser pulse or other high-power light at this time. The controller 3 controls the photoelectric conversion module 1 to stop working to avoid the current or current in the spectral chip being too large to cause damage to the spectral chip, effectively preventing the spectral chip from being burned and unable to work normally under extreme conditions such as excessive current or current.

[0068] It can be understood that if the photoelectric conversion module 1 is connected to a corresponding switch control element, the controller 3 can control the photoelectric conversion module 1 to stop working by controlling the switch control element.

[0069] In one embodiment of the present application, after controlling the photoelectric conversion module 1 to stop working, the method includes:

[0070] Determine that the input voltage of the photoelectric conversion module 1 is greater than or equal to the overvoltage voltage, or determine that the input current of the photoelectric conversion module 1 is greater than or equal to the overcurrent current, wherein the overvoltage voltage is greater than the zero-point voltage, and the overcurrent current is greater than the zero-point current;

[0071] The photoelectric conversion module 1 is controlled to stop working again.

[0072] It is understandable that after controlling the photoelectric conversion module 1 to stop working, if the controller 3 still determines that the input voltage of the photoelectric conversion module 1 is greater than or equal to the overvoltage, or the input current is greater than or equal to the overcurrent, it means that the photoelectric conversion module 1 has not been successfully shut down and the photoelectric conversion module 1 is still working. Then the controller 3 controls the photoelectric conversion module 1 to stop working again, so as to realize double protection of the spectral chip.

[0073] In one embodiment of the present application, the control method of the spectral chip further includes:

[0074] Get the temperature of the spectral chip;

[0075] If the temperature is greater than the preset value,

[0076] The photoelectric conversion module 1 is controlled to stop working.

[0077] It can be understood that during the operation of the spectral chip, the controller 3 will obtain the real-time temperature of the spectral chip and compare the real-time temperature with the preset value. When it is determined that the real-time temperature of the spectral chip is greater than the preset value, it means that the temperature of the spectral chip is too high and the voltage or current in the spectral chip may be too large. The photoelectric conversion module 1 is controlled to stop working, so that the voltage or current in the spectral chip is reduced, and the temperature of the spectral chip is reduced, thereby effectively preventing the spectral chip from burning.

[0078] It is understandable that the temperature of the spectrum chip can be detected by the temperature sensor NTC, and the controller 3 can determine the temperature of the spectrum chip by acquiring the detection data of the temperature sensor NTC.
