The following are detailed descriptions.

[0049] Example 1

[0050] See also Figure 1 , Figure 1 This is a schematic diagram of a structure of an indication circuit for indicating the status of system hardware and software disclosed in an embodiment of the present utility model. Figure 1 The indicator circuit for indicating the status of system hardware and software can be applied to electronic devices, which may include a display screen, a digital tube and an indicator circuit. The indicator circuit is used to indicate abnormalities when the display screen and the digital tube have program errors and / or power supply abnormalities, which is not limited in the embodiments of the present invention.

[0053] The monitoring circuit 10 is used to monitor the monitored system 30. When the monitored system 30 is in an abnormal working state, the monitoring circuit 10 sends a system abnormality signal to the indication circuit 20;

[0054] The indication circuit 20 is used to receive a system normal signal sent by the monitored system 30 when the monitored system 30 is in a normal working state, and output a system normal signal indication based on the system normal signal. It is also used to receive a system abnormal signal sent by the monitoring circuit 10 when the monitored system 30 is in an abnormal working state, and output a system abnormal signal indication based on the system abnormal signal.

[0055] In an embodiment of the present invention, optionally, the monitoring circuit 10 can be used to monitor the monitored system 30. When the monitored system 30 is in an abnormal working state, the monitoring circuit 10 sends a system abnormality signal to the indication circuit 20. The monitored system 30 may include a lighting system. The abnormal working state may include system software program running away, freezing, etc., such as abnormal operating logic, dead loop and other single-chip abnormal working states.

When the indicator circuit 20 receives a system abnormal signal sent by the monitoring circuit 10, the green light is off. At this time, when the power supply normal signal sent by the monitored system 30 is received, the red light is on. At this time, when the power supply abnormal signal sent by the monitored system 30 is received, the red light is off.

[0057] It can be seen that implementation Figure 1 The described indication circuit for indicating the software and hardware status of the system can monitor whether the monitored system has program abnormalities such as software runaway through the monitoring circuit, and provide signal indications of software and hardware abnormalities occurring in the monitored system through the indication circuit. It can solve the problem that when the program in the device runs away or the power supply is abnormal, the display screen or digital tube that relies on the normal operation of the microcontroller cannot display.

[0059] A first end of the first sub-indication circuit 201 is electrically connected to a second end of the monitoring circuit 10, and a second end of the first sub-indication circuit 201 is used to electrically connect to a second end of the monitored system 30. A first end of the second sub-indication circuit 202 is electrically connected to a second end of the monitoring circuit 10, and a second end of the second sub-indication circuit 202 is used to electrically connect to a second end of the monitored system 30.

[0060] The first sub-indication circuit 201 is configured to output a first type of system normal signal indication or system abnormal signal indication;

[0061] The second sub-indication circuit 202 is configured to output a second type of system normal signal indication or system abnormal signal indication.

[0062] In an embodiment of the present invention, optionally, the first sub-indicator circuit 201 can be used to output a first type of system normal signal indication or system abnormal signal indication. Taking the output signal based on the on and off of the LED light as an example, the first type of system normal signal indication includes the green light being on, and the first type of system abnormal signal indication includes the green light being off. The second sub-indicator circuit 202 can be used to output a second type of system normal signal indication or system abnormal signal indication.

This embodiment of the present invention does not limit this. In this way, displaying the system hardware and software status through different types of signals, such as light signals of different colors, is conducive to improving the comprehensiveness and accuracy of displaying the system hardware and software status.

[0063] In another optional embodiment, as Figure 2 As shown, the first sub-indication circuit 201 includes a first software status indication module 2011 and a first signal output module 2012, wherein:

[0064] A first end of the first software status indication module 2011 is used to electrically connect to a second end of the monitored system 30, a second end of the first software status indication module 2011 is electrically connected to a second end of the monitoring circuit 10, and a third end of the first software status indication module 2011 is electrically connected to the first signal output module 2012;

[0066] The first signal output module 2012 is configured to output a first type of system normal signal indication based on the system normal signal, or output a first type of system abnormal signal indication based on the system software abnormal signal.

[0067] In an embodiment of the utility model, optionally, the first software status indication module 2011 can be used to receive a system normal signal sent by the monitored system 30 when the monitored system 30 is in a normal working state, and the system normal signal may include a high-level signal. The first software status indication module 2011 can also be used to receive a system software abnormal signal sent by the monitoring circuit 10 when the monitored system 30 is in an abnormal working state, and the system software abnormal signal may include a high-level signal.

[0068] In an embodiment of the present invention, the first signal output module 2012 can optionally be configured to output a first type of system normal signal indication based on the system normal signal, i.e., a green light turns on, indicating that the system is operating normally. It can also be configured to output a first type of system abnormal signal indication based on the system software abnormal signal, i.e., a green light turns off, indicating that the system has experienced an abnormality such as a software failure. Displaying the system hardware and software status through different types of signals, such as light signals of different colors, helps improve the comprehensiveness and accuracy of displaying the system hardware and software status.

[0069] In another optional embodiment, Figure 2 As shown, the second sub-indication circuit 202 includes a second software status indication module 2021, a hardware status indication module 2022 and a second signal output module 2023, wherein:

[0070] A first end of the second software status indication module 2021 and a first end of the hardware status indication module 2022 are respectively used to electrically connect to a second end of the monitored system 30, a second end of the second software status indication module 2021 is electrically connected to a second end of the monitoring circuit 10, a third end of the second software status indication module 2021 is electrically connected to a second end of the hardware status indication module 2022, and a third end of the hardware status indication module 2022 is electrically connected to the second signal output module 2023;

[0071] The second software status indication module 2021 is configured to receive a system normal signal sent by the monitored system 30 and send the system normal signal to the second signal output module 2023 when the monitored system 30 is in a normal working state, and to receive a system software abnormality signal sent by the monitoring circuit 10 and send the system software abnormality signal to the second signal output module 2023 when the monitored system 30 is in an abnormal working state;

[0072] The hardware status indication module 2022 is used to determine whether at least one piece of system hardware in the monitored system 30 is in a system hardware abnormality state, and when at least one piece of system hardware in the monitored system 30 is in a system hardware abnormality state, send a system hardware abnormality signal to the second signal output module 2023;

[0073] The second signal output module 2023 is configured to output a second type of system normal signal indication based on the system normal signal, or output a second type of system abnormal signal indication based on the system software abnormal signal and / or the system hardware abnormal signal.

[0074] In an embodiment of the utility model, optionally, the second software status indication module 2021 can be used to receive a system normal signal sent by the monitored system 30 when the monitored system 30 is in a normal working state, and the system normal signal may include a high-level signal. The second software status indication module 2021 can also be used to receive a system software abnormal signal sent by the monitoring circuit 10 when the monitored system 30 is in an abnormal working state, and the system software abnormal signal may include a high-level signal.

[0075] In an embodiment of the utility model, optionally, the hardware status indication module 2022 can be used to determine whether at least one system hardware in the monitored system 30 is in a system hardware abnormal state. When at least one system hardware in the monitored system 30 is in a system hardware abnormal state, a system hardware abnormal signal is sent to the second signal output module 2023. For example, the hardware status indication module 2022 can be used to monitor the working status of multiple system hardware in the monitored system 30, such as the working status of multiple power supplies. When each power supply in the monitored system 30 is in a system hardware normal state, a system hardware normal signal, i.e., a high-level signal, can be sent to the second signal output module 2023 to light up the red light in the second signal output module 2023. When at least one power supply in the monitored system 30 is in a system hardware abnormal state, no system hardware normal signal is sent to the second signal output module 2023, i.e., no high-level signal is sent, and the red light is turned off.

[0076] In the embodiment of the present utility model, optionally, when the monitored system 30 is in a normal working state, the first software status indication module 2011 and the second software status indication module 2021 will receive the system normal signal sent by the monitored system 30, at this time the first signal output module 2012 lights up the green light based on the system normal signal, and the second signal output module 2023 turns off the red light based on the system normal signal. When the monitored system 30 is in an abnormal working state, the first software status indication module 2011 and the second software status indication module 2021 will receive the system software abnormality signal sent by the monitoring circuit 10. At this time, the first signal output module 2012 turns off the green light based on the system software abnormality signal, and the second signal output module 2023 receives the signal sent by the hardware status indication module 2022. When the system hardware is normal signal is received, the second signal output module 2023 lights up the red light based on the system hardware normal signal, otherwise it turns off the red light. In summary, when the monitored system 30 is operating normally, the green light is on and the red light is off. When the monitored system 30 has a software abnormality alone, the green light is off and the red light is on. When the monitored system 30 has both software and hardware abnormalities, the green light is off and the red light is off. In this way, displaying the system hardware and software status through different types of signals, such as light signals of different colors, is conducive to improving the comprehensiveness and accuracy of displaying the system hardware and software status.

[0077] It can be seen that implementation Figure 2 The described indication circuit for indicating the status of system software and hardware can display the status of system software and hardware through different types of signals, such as light signals of different colors. It can solve the problem that when the program in the device runs out of control or the power supply is abnormal, the display screen or digital tube that relies on the normal operation of the microcontroller cannot display. It improves the comprehensiveness and accuracy of displaying the status of system software and hardware, improves the ability and accuracy of full-state error indication of the device, can more comprehensively indicate the abnormal status of the system, improves the convenience of user debugging and maintenance, and enhances the user experience.

Figure 3 As shown, the first software status indication module 2011 includes a first resistor R1, a second resistor R2, a third resistor R3, a first transistor Q1 and a second transistor Q2, wherein:

[0079] The first end of the first resistor R1 is used to electrically connect to the second end of the monitored system 30, the second end of the first resistor R1 is electrically connected to the base of the first transistor Q1, the first end of the second resistor R2 is electrically connected to the second end of the monitoring circuit 10, the second end of the second resistor R2 is electrically connected to the base of the second transistor Q2, the collector of the second transistor Q2 is electrically connected to the first end of the third resistor R3, the second end of the third resistor R3 is electrically connected to the base of the first transistor Q1, the collector of the first transistor Q1 is electrically connected to the first signal output module 2012, and the emitter of the first transistor Q1 and the emitter of the second transistor Q2 are respectively used for grounding.

[0080] In the embodiment of the present invention, optionally, the first end of the first resistor R1 is used to electrically connect to the second end of the monitored system 30, that is, Figure 3 The RUN pin in the monitoring circuit 10 is used to electrically connect the second end of the monitored system 30. When the monitored system 30 is in normal working state, that is, when the system software is running normally, a high-level signal is input from the RUN pin to control the first transistor Q1 to be turned on; the first end of the second resistor R2 is electrically connected to the second end of the monitoring circuit 10, that is, Figure 3 The OUT pin is electrically connected to the second terminal of the monitoring circuit 10. When the monitoring circuit 10 detects that the monitored system 30 is in an abnormal operating state, that is, when the system software is out of control, a high level is input to the OUT pin, turning on the second transistor Q2. At this time, the base of the first transistor Q1 is low. This allows the RUN pin to receive signals indicating normal system operation, while the OUT pin receives signals indicating system software anomalies from the hardware watchdog circuit, facilitating the display of the system software status.

[0081] In another optional embodiment, Figure 3 As shown, the first signal output module 2012 includes a fourth resistor R4 and a first light emitting diode D1, wherein:

[0082] A first end of the fourth resistor R4 is electrically connected to the collector of the first transistor Q1 , and a second end of the fourth resistor R4 is electrically connected to the first light emitting diode D1 ;

[0083] The first light emitting diode D1 is configured to output a first type of system normal signal indication based on the system normal signal, or output a first type of system abnormal signal indication based on the system software abnormal signal.

[0084] In an embodiment of the present invention, optionally, the first light-emitting diode D1 can be used to output a first type of system normal signal indication based on the system normal signal, that is, the green light is on. Specifically, when the monitored system 30 is in a normal working state, that is, the system software is running normally, a high-level signal is input from the RUN pin to control the first transistor Q1 to be turned on, and the first light-emitting diode D1 is on. The first light-emitting diode D1 can also be used to output a first type of system abnormal signal indication based on the system software abnormal signal, that is, the green light is off. Specifically, when the monitoring circuit 10 detects that the monitored system 30 is in an abnormal working state, that is, the system software is running away, a high level is input from the OUT pin to control the second transistor Q2 to be turned on, and the base of the first transistor Q1 is low, and the first light-emitting diode D1 is turned off.

[0085] It can be seen that implementation Figure 3 The described first sub-indicator circuit can receive a signal indicating normal system operation through the RUN pin, receive a system software abnormality signal sent by the hardware watchdog circuit through the OUT pin, and display the system software status through a green light. This can solve the problem that when the program in the device runs away or the power supply is abnormal, the display screen or digital tube that relies on the normal operation of the microcontroller cannot display, thereby improving the comprehensiveness and accuracy of the display of the system software status.

[0086] In another optional embodiment, Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a second sub-indicator circuit disclosed in an embodiment of the present utility model. Figure 4 As shown, the second software status indication module 2021 includes a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a third transistor Q3 and a fourth transistor Q4, wherein:

[0087] The first end of the fifth resistor R5 is used to electrically connect to the second end of the monitored system 30, the first end of the sixth resistor R6 is electrically connected to the second end of the monitoring circuit 10, the second end of the sixth resistor R6 is electrically connected to the base of the fourth transistor Q4, the collector of the fourth transistor Q4 is electrically connected to the first end of the seventh resistor R7, the second end of the fifth resistor R5 and the second end of the seventh resistor R7 are respectively electrically connected to the base of the third transistor Q3, the collector of the third transistor Q3 is electrically connected to the first end of the eighth resistor R8, the second end of the eighth resistor R8 is electrically connected to the second end of the hardware status indication module 2022, and the emitter of the third transistor Q3 and the emitter of the fourth transistor Q4 are respectively used for grounding.

[0088] In the embodiment of the present invention, optionally, the first end of the fifth resistor R5 is used to electrically connect to the second end of the monitored system 30, that is, Figure 4The EN POWER pin in the monitoring circuit 10 is used to electrically connect the second end of the monitored system 30. When the monitored system 30 is in normal working state, that is, when the system software is running normally, a high-level signal is input from the EN POWER pin to control the third transistor Q3 to be turned on; the first end of the sixth resistor R6 is electrically connected to the second end of the monitoring circuit 10, that is, Figure 4 The OUT pin is electrically connected to the second end of the monitoring circuit 10. When the monitoring circuit 10 detects that the monitored system 30 is in an abnormal working state, that is, the system software is out of order, a high level is inputted by the OUT pin to control the fourth transistor Q4 to be turned on. The high level inputted by the OUT pin has a higher priority than the high level signal inputted by the EN POWER pin, that is, the priority of the monitoring result of the monitored system 30 monitored by the monitoring circuit 10 is higher than the software control signal of the monitored system 30.

[0089] In another optional embodiment, Figure 4 As shown, the hardware status indication module 2022 includes a first chip U1, a ninth resistor R9, and a fifth transistor Q5, wherein:

[0090] The input end of the first chip U1 is used to electrically connect to the second end of the monitored system 30, the output end of the first chip U1 is electrically connected to the first end of the ninth resistor R9, the second end of the ninth resistor R9 is electrically connected to the base of the fifth transistor Q5, the collector of the fifth transistor Q5 is electrically connected to the second signal output module 2023, and the emitter of the fifth transistor Q5 is used for grounding.

[0091] In an embodiment of the present invention, optionally, the input end of the first chip U1 is used to electrically connect to the second end of the monitored system 30. The first chip U1 is a logic AND gate chip. Specifically, the input end of the first chip U1 is used to electrically connect to at least one power supply in the monitored system 30. When the power supply is normal, a determination signal is output after resistor voltage division and then acts on the logic AND gate chip U1. According to the characteristics of the logic AND gate, only when all power supplies in the monitored system 30 are normal, a high-level signal will be output to turn on the fifth transistor Q5.

[0092] In another optional embodiment, Figure 4 As shown, the second signal output module 2023 includes a tenth resistor R10 and a second light emitting diode D2, wherein:

[0093] A first end of the tenth resistor R10 is electrically connected to the collector of the fifth transistor Q5 , and a second end of the tenth resistor R10 is electrically connected to the second light emitting diode D2 ;

[0094] The second light emitting diode D2 is used to output a second type of system normal signal indication based on the system normal signal, or to output a second type of system abnormal signal indication based on the system software abnormal signal and / or the system hardware abnormal signal.

[0095] Optionally, the second light-emitting diode D2 can be used to output a second type of system normal signal indication based on the system normal signal, that is, the red light is off. Specifically, when the monitored system 30 is in a normal working state, that is, the system software is running normally, a high-level signal is input from the EN POWER pin to control the third transistor Q3 to be turned on, and the second light-emitting diode D2 is turned off at this time; the second light-emitting diode D2 can also be used to output a second type of system abnormal signal indication based on the system software abnormal signal and / or the system hardware abnormal signal. Specifically, when the monitoring circuit 10 detects that the monitored system 30 is in an abnormal working state, that is, the system software is running away, a high level is input from the OUT pin to control the fourth transistor Q4 to be turned on. At this time, when all power supplies in the monitored system 30 are normal, a high-level signal is output to turn on the fifth transistor Q5, that is, the green light is off and the red light is on. When at least one power supply in the monitored system 30 is abnormal, the green light is off and the red light is off.

[0096] It can be seen that implementation Figure 4 The second sub-indicator circuit described can receive the system's software normal signal through the EN POWER pin and the software abnormality signal sent by the hardware watchdog circuit through the OUT pin. It determines whether the hardware power supply in the system is normal through a logic AND gate and displays it through a red light. This can solve the problem that the display screen or digital tube that relies on the normal operation of the microcontroller cannot display when the program in the device runs out of control or the power supply is abnormal, thereby improving the comprehensiveness and accuracy of the display system hardware status.

[0097] In another optional embodiment, Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of a monitoring circuit disclosed in an embodiment of the present utility model. Figure 5 As shown, the monitoring circuit may include a button K1, a second chip U2, an eleventh resistor R11 and a twelfth resistor R12, wherein: the first end of the button K1 is used for grounding, the second end of the button K1 is electrically connected to the MR# pin of the second chip U2, the first end of the eleventh resistor R11 is electrically connected to the RESET pin of the second chip U2, and the first end of the twelfth resistor R12 is electrically connected to the RESET# pin of the second chip U2.

[0098] In an embodiment of the present invention, the monitoring circuit 10 may optionally include a hardware watchdog circuit. The working logic of the hardware watchdog circuit is as follows: the software program in the monitored system 30 needs to generate a corresponding reset pulse at the WDI pin of the second chip U2 within a preset time period. When the reset pulse is generated, the internal timer of the hardware watchdog circuit is cleared, and the hardware watchdog circuit does not perform a reset operation. The preset time period can be customized, for example, 1.6S. When the software program in the monitoring system 30 runs away and a program abnormality occurs, such as an abnormal operating logic abnormality, an infinite loop, or other abnormal working state of the microcontroller, and the program cannot be reset as scheduled, corresponding high and low pulse signals will be generated at the RESET and RESET# pins to drive the indicator light to work, which is used to indicate the system status. The eleventh resistor R11 and the twelfth resistor R12 play a distinguishing role. Welding the eleventh resistor R11 represents the use of a high-level pulse signal, and welding the twelfth resistor R12 represents the use of a low-level pulse signal. The button K1 can be used to manually reset the chip once.

[0099] In another optional embodiment, Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of another indicator circuit for indicating the status of system software and hardware disclosed in an embodiment of the present utility model. Figure 6 As shown, the indication circuit for indicating the system software and hardware status may also include a signal conversion circuit 40, wherein: the first end of the signal conversion circuit 40 is electrically connected to the second end of the monitoring circuit 10, and the second end of the signal conversion circuit 40 is electrically connected to the first end of the indication circuit 20; further optionally, the signal conversion circuit 40 may include a clearing module 401 and a signal conversion module 402, and the signal conversion module 402 may be a D trigger, specifically, one end of the clearing module 401 is electrically connected to the first end of the signal conversion module 402, the second end of the signal conversion module 402 is electrically connected to the second end of the monitoring circuit 10, and the third end of the signal conversion module 402 is electrically connected to the first end of the indication circuit 20.

[0100] In the embodiment of the present utility model, optionally, Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of a signal conversion circuit disclosed in an embodiment of the present utility model. Figure 7As shown, the signal conversion circuit 40 may include a clearing module 401 and a signal conversion module 402, the clearing module 401 includes a first capacitor C1 and a thirteenth resistor R13, the signal conversion module 402 includes a second capacitor C2 and a third chip U3, wherein the first end of the first capacitor C1 and the first end of the thirteenth resistor R13 are respectively electrically connected to the RD pin of the third chip U3, the second end of the first capacitor C1 is used for grounding, the first end of the second capacitor C2 is used for grounding, the second end of the second capacitor C2 is electrically connected to the SD pin of the third chip U3, the CP pin of the third chip U3 is respectively electrically connected to the second end of the eleventh resistor R11 and the second end of the twelfth resistor R12, the D pin of the third chip U3 is electrically connected to the Q pin of the third chip U3, and the OUT pin of the third chip U3 is respectively electrically connected Figure 3 OUT pin and Figure 4 The OUT pin is electrically connected to the first end of the second resistor R2 and the first end of the sixth resistor R6.

[0101] In an embodiment of the utility model, optionally, when the first capacitor C1 is powered on, it is approximately in a short-circuit state. At this time, the output state of the D flip-flop is set to a low level. As the first capacitor C1 slowly completes charging, the first capacitor C1 is at a high level. At this time, the D flip-flop retains its original low level state; the D pin of the third chip U3 is electrically connected to the Q pin of the third chip U3. Each time a rising edge appears at the CP pin, the output will automatically be reversed, that is, when the D flip-flop receives the trigger level of the hardware watchdog circuit, the output state will flip to a high level, driving the corresponding indicator light.

[0102] It can be seen that implementation Figure 7 The described signal conversion circuit can convert the pulse signal of the monitoring circuit into a more stable high-level signal and send it to the indication circuit, thereby improving the accuracy and stability of the indication circuit in displaying the system software and hardware status, and improving the ability and accuracy of full-state error indication of the device.

[0103] The working principle of the indicator circuit used to indicate the system hardware and software status in this utility model is as follows:

[0104] In the embodiment of the present invention, a hardware watchdog circuit is used to monitor whether the monitored system has abnormal working conditions such as software program running away. When it is detected that the monitored system has abnormal working conditions such as software program running away, the hardware watchdog circuit sends a pulse signal to the D trigger, and the D trigger converts the pulse signal into a stable high-level signal, and sends the high-level signal to the first sub-indication circuit and the second sub-indication circuit, wherein: in the first sub-indication circuit, when the software of the monitored system is running normally, the monitored system will send a high level to the first sub-indication circuit, and light up the green LED in the first sub-indication circuit. When the first sub-indication circuit receives the high-level signal sent by the D trigger, it will turn off the green LED; in the second sub-indication circuit, the hardware status indication module The logic AND gate in the circuit determines whether the status of the power supply hardware in the monitored system is all normal. When the status of the power supply hardware in the monitored system is all normal, a high-level signal is output to light up the red LED in the second sub-indication circuit. When the software of the monitored system runs normally, the monitored system will send a high level to the second sub-indication circuit to turn off the red LED in the second sub-indication circuit. When the second sub-indication circuit receives a high-level signal sent by the D trigger and the status of the power supply hardware in the monitored system is all normal, the red LED in the second sub-indication circuit is turned on. When the second sub-indication circuit receives a high-level signal sent by the D trigger and the status of at least one power supply hardware in the monitored system is abnormal, the red LED in the second sub-indication circuit is turned off. It can be seen that the indicator circuit for indicating the system software and hardware status of this solution can monitor whether the monitored system has program abnormalities such as software running away through the monitoring circuit, and provide signal indications of software abnormalities and hardware abnormalities in the monitored system through the indicator circuit. It can solve the problem that when the program in the device runs away and the power supply is abnormal, the display screen or digital tube that relies on the normal operation of the single-chip microcomputer cannot display. It improves the comprehensiveness and accuracy of displaying the system software and hardware status, improves the ability and accuracy of full-state error indication of the device, can more comprehensively indicate the abnormal status of the system, improve the convenience of user debugging and maintenance, and enhance the user experience.
