Abstract
An electronic component real-time protection and monitoring notification system includes a primary controller and at least one protection notifier. The primary controller utilizes a feedback control circuit to control a control signal of an electronic component. Each protection notifier is connected in series with the primary controller and is independent of each other. When the parameter such as the temperature, voltage, or current of the controlled electrical component exceeds the safety requirements, each protection notifier clamps the primary controller from outputting the control signal in real-time and utilizes the photocoupler to issue a monitoring notification signal. By clamping the operation of the controlled electronic component, it is able to identify which part of the electronic component malfunctions. Through the aforementioned configuration, an effective and real-time monitoring function may be provided, thus decreasing the repairing costs.

[0033] The primary differential amplifier 40 is connected to the electronic component 30 and a port of the positive end 111 of the pre-operational amplifier 11 that receives the primary threshold value M1, and the primary differential amplifier 40 converts the polarity of the primary measurement value M1 to be opposite to the polarity of the primary threshold value THR1. The positive differential amplifier 50 and the negative differential amplifier 60 are respectively connected to the corresponding positive circuit 21 and the negative circuit 22, both the positive differential amplifier 50 and the negative differential amplifier 60 are connected to the electronic component 30, and both the positive differential amplifier 50 and the negative differential amplifier 60 convert the polarity of each of the secondary measurement values M2 to be opposite to the polarity of the secondary threshold value THR2. The microprocessor 70 is connected to the primary controller 10 and connected to the photocouplers 212 and 222 of the positive circuit 21 and the negative circuit 22 of the protection notifier 20.
[0034] Each protection notifier 20 is cascaded and connected to the node N and includes a positive circuit 21 and a negative circuit 22. The positive circuit 21 includes a monitoring operational amplifier 211, a photocoupler 212, and a diode 213. The negative circuit 22 includes a monitoring operational amplifier 221, a photocoupler 222, and a diode 223. The monitoring operational amplifier 211 of the positive circuit 21 has a positive end 2111, a negative end 2112, and an output end 2113. The output end 2113 of the monitoring operational amplifier 211 of the positive circuit 21 is connected to the diode 213 and the photocoupler 212. The diode 213 of the positive circuit 21 is connected to the negative end 2113 of the monitoring operational amplifier 221 and the photocoupler 212 of the positive circuit 21 is connected to the node N. The positive end 2111 of the monitoring operational amplifier 211 of the positive circuit 21 is connected to a secondary threshold value THR2 and a secondary measurement value M2 opposite in polarity to the secondary threshold value THR2. The monitoring operational amplifier 221 of the negative circuit 22 has the positive end 2211, the negative end 2212, and the output end 2213. The output end 2213 of the monitoring operational amplifier 221 of the negative circuit 22 is connected to the diode 223 and the photocoupler 222. The diode 223 of the negative circuit 22 is connected to the negative end 2213 of the monitoring operational amplifier 221 and the photocoupler 222 of the negative circuit 22 is connected to the node N. The positive end 2211 of the monitoring operational amplifier 221 of the negative circuit 22 is connected to a secondary threshold value THR2 and a secondary measurement value M2 opposite in polarity to the secondary threshold value THR2.
[0035] When the monitoring operational amplifier 211 or 221 of the positive circuit 21 or the negative circuit 22 operates to determine a difference value between the secondary threshold value THR2 and the secondary measurement value M2 to be substantially equal to zero such that the diode 213 or 223 of the positive circuit 21 or the negative circuit 22 is reverse-biased, and the photocoupler 212 or 222 of the positive circuit 21 or the negative circuit 22 is turned on to issue a monitoring notification signal S1 or S2 to the microprocessor 70; the microprocessor 70 receives the monitoring notification signal S1 or S2 and sends a stop signal to the primary controller 10, the post-operational amplifier 12 stops outputting the control signal CTR, and the electronic component 30 stops operating and the microprocessor 70 identifies which part of the electronic component 30 malfunctions according to the monitoring notification signal S1 or S2 received. When the monitoring operational amplifier 211 or 221 of the positive circuit 21 or the negative circuit 22 operates to determine the difference value between the secondary threshold value THR2 and the secondary measurement value M2 to be substantially larger than zero such that the diode 213 or 223 of the positive circuit 21 or the negative circuit 22 is forward-biased, and the photocoupler 212 or 222 of the positive circuit 21 or the negative circuit 22 is turned off. The post-operational amplifier 12 maintains outputting the control signal CTR to the electronic component 30. Through the aforementioned configuration, it is able to identify which part of the electronic component malfunctions, thus decreasing the repairing costs.
[0036] It should be noted that the positive end 111 and the output end 113 of the pre-operational amplifier 11 are both configured with a resistance R to appropriately adjust the primary threshold value THR1 and the primary measurement value M1; the positive end 121, the negative end 122, and the output end 123 of the post-operational amplifier 12 are configured with a resistance R or a capacitance C to properly adjust the control signal CTR. The positive ends 2111 and 2211 of the monitoring operational amplifier 211 of the positive circuit 21 and the monitoring operational amplifier 221 of the negative circuit 22 are configured with a resistance R to appropriately adjust the secondary threshold value THR2 and the secondary measurement value M2. The diodes 213 and 223 of the monitoring operational amplifier 211 of the positive circuit 21 and the monitoring operational amplifier 221 of the negative circuit 22 are also connected in parallel with a capacitance C, and the photocouplers 212 and 222 are also connected to the power supply end VIO (usually the operating voltage of the microprocessor 70) to enable the photocouplers 212 and 222 to operate normally. The aforementioned configuration is an example and the configuration of a resistance R and a capacitance C may be adjusted according to actual needs without being limited in the scope exemplified by the present disclosure.
[0037] Specifically, the primary measurement value M1 is a primary parameter for measuring the electronic component 30, each of the secondary measurement values M2 is a secondary parameter for measuring the electronic component 30, and the primary parameter is different from each of the secondary parameters. For instance, the primary parameter may be voltage, the two secondary parameters may be electrical current and temperature, and the number of secondary parameters may be adjusted according to the parameters of the electronic component 30 to be measured. Therefore, the number of protection notifiers 20 should also be adjusted according to actual needs without being limited in the scope exemplified by the present disclosure.
[0038] In addition, the polarity of the secondary parameter may be negative or positive. If the polarity of the secondary parameter is negative, the secondary measurement value M2 is sent to the negative circuit 22, and the negative circuit 22 operates accordingly; if the polarity of the secondary parameter is positive, the secondary measurement value M2 is sent to the positive circuit 21, and the positive circuit 21 operates accordingly. In other words, one of the positive circuit 21 and the negative circuit 22 is selected for operation according to the polarity of the corresponding secondary parameter M2.

[0041] Specifically, the +Vclamp port or Vclamp port of the protection notifier 20 (X5) receives the secondary threshold value THR2 (may also be denoted as +Vclamp1 or Vclamp1), the +Vclamp port or Vclamp port of the protection notifier 20 (X2) receives the secondary threshold value THR2 (may also be denoted as +Vclamp2 or Vclamp2), and the secondary threshold value THR2 of the protection notifier 20 (X5) is different from that of the protection notifier 20 (X2). The port Vctr1 at which the positive end 111 of the pre-operational amplifier 11 receives the voltage receives the primary threshold value THR1. The Vin+ port of the positive differential amplifier 50 (X4) receives the VT2 voltage of the resistance R4, and the Vin port thereof receives the VT1 voltage of the resistance R4. Since the VT1 voltage is larger than the VT2 voltage, the Vprotect1 voltage (secondary measurement value M2) may be opposite in polarity to the corresponding secondary threshold value THR2, thus obtaining the difference value between the Vprotect1 voltage and the secondary threshold value THR2. The Vin+ port of the positive differential amplifier 50 (X) receives the VP2 voltage of the resistance R47, and the Vin port thereof receives the VP1 voltage of the resistance R47. Since the VP1 voltage is larger than the VP2 voltage, the Vprotect2 voltage (secondary measurement value M2) may be opposite in polarity to the corresponding secondary threshold value THR2, thus obtaining the difference value between the Vprotect2 voltage and the secondary threshold value THR2. The Vin+ port of the primary differential amplifier 40 is grounded and the Vin port thereof receives the VT2 voltage of the resistance R4. Therefore, the Vfb1 voltage may be opposite in polarity to the primary threshold value THR1, thus obtaining the difference value between the Vfb1 voltage and the primary threshold value THR1.
[0042] It should be noted that the protection notifier 20 (X5) and the protection notifier 20 (X2) also include a positive circuit 21 and a negative circuit 22 as shown in

[0045] During the period from 5 msec to 10 msec, the load is simulated to be short-circuited at 6.5 msec to 7.8 msec to increase the load current I.sub.L to more than 10 A (exceeding the setting for the monitoring load current). The present disclosure actively clamps the input of the power driver at the moment so that the load voltage V.sub.L drops to less than 10V and the load current I.sub.L does not exceed 10 A. In the meantime, the protection notifier 20 (X5) of
[0046] During the period from 10 msec to 15 msec, the internal monitoring component (resistance R47) of the power driver is simulated to malfunction from 11.5 msec to 12.5 msec due to degradation, resulting in an increase in the resistance value of the resistance R47. When the same load current I.sub.L is 5 A, the cross voltage of the internal monitoring component (resistance R47) exceeds the monitoring set voltage of the power driver by 2V. The present disclosure actively clamps the input of the power driver at the moment, so that the cross voltage of the internal monitoring component (resistance R47) does not exceed 2V, and the load voltage V.sub.L drops simultaneously to less than 10V. In the meantime, the protection notifier 20 (X2) of
[0047] The output voltage range of the positive polarity is discussed on the aforementioned abnormal events only. When the output voltage range of the negative polarity is abnormal, the negative circuit 22 of the protection notifier 20 (X2, X5) is switched to complete the same protection operation mode. The only difference is the opposite in polarity, so the similar descriptions are not to be described herein.
[0048] It should be noted that the secondary measurement value M2 required by the positive circuit 21 and the negative circuit 22 may be, for example, the same unit of voltage; however, the corresponding detected components are different, so parameters of different components are detected. Therefore, the positive circuit 21 and the negative circuit 22 may detect the parameters of different components and operate in the same unit of voltage. This is only an example without limiting the scope of the disclosure to be protected.

[0051] Specifically, the current-to-voltage converter 80 converts the primary measurement value M1 into a corresponding voltage and sends it to the primary differential amplifier 40, the primary differential amplifier 40 applies polarity conversion to the primary measurement M1 which has been converted to voltage and sends it to the primary controller 10, and the primary controller 10 outputs a control signal CTR to control the current of the light source L accordingly.
[0052] The thermocouple converter 90 converts the secondary measurement value M21 into a corresponding voltage value and sends it to the positive differential amplifier 50 or the negative differential amplifier 60, and the positive differential amplifier 50 or the negative differential amplifier 60 applies polarity conversion to the secondary measurement value M21 which has been converted into voltage and sends it to the protection notifier 20. The protection notifier 20 operates to determine the difference value between the secondary threshold value THR21 and the secondary measurement value M21. If the difference value between the secondary threshold value THR21 and the secondary measurement value M21 is zero, the diode 213 or 223 of the positive circuit 21 and the negative circuit 22 is reverse-biased such that the photocoupler 212 or 222 of the positive circuit 21 or the negative circuit 22 is turned on to issue a monitoring notification signal S1 or S2 to the microprocessor 70; the microprocessor 70 receives the monitoring notification signal S1 or S2 and sends a stop signal to the primary controller 10, the post-operational amplifier 12 stops outputting the control signal CTR, and the light source L stops operating. If the difference value between the secondary threshold value THR21 and the secondary measurement value M21 is larger than zero, the diode 213 or 223 of the positive circuit 21 and the negative circuit 22 is forward-biased such that the photocoupler 212 or 222 of the positive circuit 21 or the negative circuit 22 is turned off; the post-operational amplifier 12 maintains outputting the control signal CTR to the light source.
[0053] The photoelectric converter 90 converts the secondary measurement value M22 into a corresponding voltage value and sends it to the positive differential amplifier 50 or the negative differential amplifier 60, and the positive differential amplifier 50 or the negative differential amplifier 60 applies polarity conversion to the secondary measurement value M22 which has been converted into voltage and sends it to the protection notifier 20. The protection notifier 20 operates to determine the difference value between the secondary threshold value THR22 and the secondary measurement value M22. If the difference value between the secondary threshold value THR22 and the secondary measurement value M22 is zero, the diode 213 or 223 of the positive circuit 21 and the negative circuit 22 is reverse-biased such that the photocoupler 212 or 222 of the positive circuit 21 or the negative circuit 22 is turned on to issue a monitoring notification signal S1 or S2 to the microprocessor 70; the microprocessor 70 receives the monitoring notification signal S1 or S2 and sends a stop signal to the primary controller 10, the post-operational amplifier 12 stops outputting the control signal CTR, and the light source L stops operating.

[0054] Specifically, the monitoring notification signal M corresponding to the protection notifier 20 having the secondary threshold value THR21 and the monitoring notification signal S1 or S2 corresponding to the protection notifier 20 having the secondary threshold value THR22 are independent of each other and do not affect each other. That is, the monitoring notification signals M are independent of each other.
[0055] Accordingly, the electronic component real-time protection and monitoring notification system of the present disclosure stops the operation of the electronic component 30 in real-time through the notifications of the primary controller 10 and each protection notifier 20. In summary, the electronic component real-time protection and monitoring notification system of the present disclosure has the advantages as mentioned above and is able to identify which part of the electronic component malfunctions.
[0056] The above description is merely illustrative rather than restrictive. Any equivalent modifications or alterations without departing from the spirit and scope of the present disclosure are intended to be included in the following claims.
