Description of Related Art

As technology evolves and advances, electric apparatuses that can be connected to networks are no longer limited to desktop computers, notebook computers, and smartphones. Instead, it is expected that electric apparatuses of any type can all be connected to networks so that they can be managed and monitored at any time. For example, in the development of a smart city, street lights, traffic signals, and other outdoor electric apparatuses (e.g., outdoor cameras) can all be connected to networks. However, it is likely that the electric apparatuses connected to networks sometimes fail and cannot operate normally. Moreover, it is also likely that where the electric apparatuses are installed is far away from a management agency of the electric apparatuses. Therefore, inspecting and repairing the electric apparatuses not only take much time but also take much labor.

Moreover, the power measurement module 123 measures a power (or a voltage and a current) of at least one of the input power PI and the output power PO2 to obtain power utilizing information IFO2 of the electronic apparatus 920. In an embodiment of the invention, the power measurement module 123 is implemented as a meter, for example, but the invention is not limited hereto.

The communication module 125 is coupled to the processing module 124 and functions as a communication interface between the processing module 124 and the remote apparatus 140. In an embodiment of the invention, the communication module 125 may also be integrated in the processing module 124. In an embodiment of the invention, the communication module 125 includes, for example, a wireless communication module or a wired communication module, or includes both of a wireless communication module and a wired communication module. The wireless communication module is, for example, a Bluetooth module, a Bluetooth Low Energy (BLE) module, a Wi-Fi module, a global system for mobile communication (GSM) module, a code division multiple access (CDMA) module, a wideband CDMA (WCDMA) module, a CDMA-2000 module, a time division multiple access (TDMA) module, a worldwide interoperability for microwave access (WiMAX) module, a long term evolution (LTE) module, a wireless local area network (WLAN) module, an ultra wideband (UWB) module, or a combination of the modules above, but the invention is not limited hereto. The wired communication module is, for example, a local area network (LAN) interface module, but the invention is not limited hereto.

The processing module 124 is coupled to the switching circuits 122_1 and 122_2 to respectively control switch of the switching circuits 122_1 and 122_2. Moreover, the processing module 124 is coupled to the power measurement module 123 to receive the power utilizing information IFO1 and IFO2. In an embodiment of the invention, the processing module 124 is hardware, firmware, or software or machine-executable program codes stored in a memory and loaded and executed by a microprocessor or a digital signal processor (DSP), for example. If implemented as hardware, the processing module 124 may be implemented as one single integrated circuit chip or may be implemented as a plurality of circuit chips, but the invention is not limited hereto. The plurality of circuit chips or the one single integrated circuit chip may be implemented as an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA). The memory is, for example, a random access memory, a read-only memory, a flash memory, etc.

In an embodiment of the invention, the remote apparatus 140 collects the power utilizing information IFO1 (IFO2) of the electronic apparatus 910 (920) in a specific time period, and performs a big data analysis on the power utilizing information IFO1 (IFO2) in the specific time period to obtain reference information IFR1 (IFR2) of the electronic apparatus 910 (920), but the invention is not limited hereto. In another embodiment of the invention, the reference information IFR1 (IFR2) of the electronic apparatus 910 (920) may be a reference power value, a reference voltage value, or a reference current value that is pre-set by a user, for example.

In an embodiment of the invention, the processing module 124 determines an operating status of the electronic apparatus 910 by comparing the power utilizing information IFO1 of the electronic apparatus 910 with the reference information IFR1 and determines an operating status of the electronic apparatus 920 by comparing the power utilizing information IFO2 of the electronic apparatus 920 with the reference information IFR2. When a difference between the power utilizing information IFO1 and the reference information IFR1 is greater than a threshold value, the processing module 124 determines that the operating status of the electronic apparatus 910 is abnormal and transmits abnormality information to the remote apparatus 140 via the communication module 125. The remote apparatus 140 then determines whether to reset the electronic apparatus 910 according to the abnormality information. If the remote apparatus 140 determines to reset the electronic apparatus 910, the remote apparatus 140 transmits reset information to the processing module 124, and the processing module 124 then disconnects and re-connects the switching circuit 122_1 according to the reset information to reset the electronic apparatus 910. Similarly, when a difference between the power utilizing information IFO2 and the reference information IFR2 is greater than a threshold value, the processing module 124 determines that the operating status of the electronic apparatus 920 is abnormal and transmits abnormality information to the remote apparatus 140 via the communication module 125. The remote apparatus 140 then determines whether to reset the electronic apparatus 920 according to the abnormality information. If the remote apparatus 140 determines to reset the electronic apparatus 920, the remote apparatus 140 transmits reset information to the processing module 124, and the processing module 124 then disconnects and re-connects the switching circuit 122_2 according to the reset information to reset the electronic apparatus 920.

In another embodiment of the invention, the processing module 124 may also transmit the power utilizing information IFO1 and IFO2 of the electronic apparatuses 910 and 920 to the remote apparatus 140 (via the communication module 125). Then, the remote apparatus 140 determines the operating status of the electronic apparatus 910 by comparing the power utilizing information IFO1 with the reference information IFR1 and determines the operating status of the electronic apparatus 920 by comparing the power utilizing information IFO2 with the reference information IFR2. When the difference between the power utilizing information IFO1 of the electronic apparatus 910 and the reference information IFR1 is greater than a threshold value, the remote apparatus 140 determines whether the electronic apparatus 910 is abnormal and determines whether to reset the electronic apparatus 910. If the remote apparatus 140 determines that the electronic apparatus 910 is indeed abnormal and determines to reset the electronic apparatus 910, the remote apparatus 140 transmits reset information to the processing module 124, and the processing module 124 then disconnects and re-connects the switching circuit 122_1 according to the reset information to reset the electronic apparatus 910. Similarly, when the difference between the power utilizing information IFO2 of the electronic apparatus 920 and the reference information IFR2 is greater than a threshold value, the remote apparatus 140 determines whether the electronic apparatus 920 is abnormal and determines whether to reset the electronic apparatus 920. If the remote apparatus 140 determines that the electronic apparatus 920 is indeed abnormal and determines to reset the electronic apparatus 920, the remote apparatus 140 transmits reset information to the processing module 124, and the processing module 124 then disconnects and re-connects the switching circuit 122_2 according to the reset information to reset the electronic apparatus 920.

In an embodiment of the invention, the processing module 124 includes a storage (not illustrated), and the storage is configured to store the power utilizing information IFO1 and the reference information IFR1 of the electronic apparatus 910 and the power utilizing information IFO2 and the reference information IFR2 of the electronic apparatus 920, but the invention is not limited hereto.

Referring to both FIG. 1 and FIG. 3, FIG. 3 is a block schematic diagram illustrating a monitoring apparatus according to another embodiment of the invention. A monitoring apparatus 120′ includes a power-supply circuit 121, switching circuits 122_1 and 122_2, a power measurement module 123, a processing module 124, a communication module 125, and a timer circuit 326, but the invention is not limited hereto. Implementations and operations of the power-supply circuit 121, the switching circuits 122_1 and 122_2, the power measurement module 123, the processing module 124, and the communication module 125 of FIG. 3 are respectively similar to those of the power-supply circuit 121, the switching circuits 122_1 and 122_2, the power measurement module 123, the processing module 124, and the communication module 125 of FIG. 2. Therefore, reference may be made to the relevant descriptions of FIG. 2 above, and the descriptions shall not be repeated here.

The timer circuit 326 is coupled to the processing module 124. The timer circuit 326 functions as a failover apparatus for resetting (or rebooting) the monitoring apparatus 120′ and the electronic apparatuses 910, 920 when the processing module 124 or the communication module 125 is abnormal. Specifically, the timer circuit 326 calculates time to generate a timing value. When the timing value is equal to a first time length TL1, the timer circuit 326 generates a reboot signal SRB for the processing module 124, so that the processing module 124 can reset the monitoring apparatus 120′ and the electronic apparatuses 910, 920 in response to the reboot signal SRB.

In an embodiment of the invention, the processing module 124 is configured to start the timer circuit 326 at a predetermined time point to have the timer circuit 326 start to calculate time. Moreover, after starting the timer circuit 326, the processing module 124 transmits a timing start signal to the remote apparatus 140 via the communication module 125. The remote apparatus 140 transmits a response signal responding to the timing start signal. If the processing module 124 receives the response signal from the remote apparatus 140 via the communication module 125, it means that the communication module 125 is operating normally. Therefore, the processing module 124 disables the timer circuit 326 to prevent the timer circuit 326 from generating the reboot signal SRB. Conversely, when the communication module 125 is abnormal, the processing module 124 cannot transmit the timing start signal to the remote apparatus 140 via the communication module 125 or cannot receive the response signal associated with the timing start signal from the remote apparatus 140 via the communication module 125. Therefore, the processing module 124 does not disable the timer circuit 326, and the timer circuit 326 will continue to calculate time. Once the timing value of the timer circuit 326 is equal to the first time length TL1, the timer circuit 326 generates the reboot signal SRB for the processing module 124, such that the processing module 124 resets the monitoring apparatus 120′ and the electronic apparatuses 910, 920 in response to the reboot signal SRB.

In another embodiment of the invention, in the case where the processing module 124 is operating normally, the processing module 124 may output a return-to-zero signal SZO to the timer circuit 326 at every interval of a second time length TL2 to set the timing value of the timer circuit 326 to zero. Specifically, the second time length TL2 is less than the first time length TL1. Accordingly, when the processing module 124 is abnormal and cannot generate the return-to-zero signal SZO, the timer circuit 326 will continue to calculate time. Once the timing value of the timer circuit 326 is equal to the first time length TL1, the timer circuit 326 generates a reboot signal SRB for the processing module 124 to reset the monitoring apparatus 120′ and the electronic apparatuses 910, 920.

In yet another embodiment of the invention, the remote apparatus 140 may transmit return-to-zero information at every interval of the second time length TL2. In the case where the processing module 124 and the communication module 125 are operating normally, the processing module 124 may receive the return-to-zero information via the communication module 125 and generate a return-to-zero signal SZO accordingly for the timer circuit 326 to set the timing value of the timer circuit 326 to zero. Specifically, the second time length TL2 is less than the first time length TL1. Accordingly, when at least one of the communication module 125 and the processing module 124 is abnormal, the processing module 124 cannot receive the return-to-zero information, or the processing module 124 can receive the return-to-zero information but cannot generate the return-to-zero signal SZO. Therefore, the timer circuit 326 will continue to calculate time. Once the timing value of the timer circuit 326 is equal to the first time length TL1, the timer circuit 326 generates a reboot signal SRB for the processing module 124 to reset the monitoring apparatus 120′ and the electronic apparatuses 910, 920.

In the foregoing embodiments of the invention, the first time length TL1 may be set through the remote apparatus 140. Specifically, the remote apparatus 140 may transmit setting information to the processing module 124 via the communication module 125, and the processing module 124 may set the first time length TL1 according to the setting information. However, the invention is not limited hereto.

FIG. 4 is a flowchart illustrating steps of a monitoring method according to an embodiment of the invention. As shown in FIG. 4, the monitoring method is applicable to the monitoring system 100 of FIG. 1, the monitoring apparatus 120 of FIG. 2, and the monitoring apparatus 120′ of FIG. 3, but the invention is not limited hereto. Referring to FIG. 1, FIG. 3, and FIG. 4, first, in step S410 of FIG. 4, output powers PO1, PO2 are generated by the power-supply circuit 121 according to an input power PI. Next, in step S420, the output power PO1 (PO2) is transmitted to the electronic apparatus 910 (920) by the switching circuit 122_1 (122_2). Afterwards, in step S430, a voltage and a current of at least one of the input power PI and the output power PO1 (PO2) are measured by the power measurement module 123 to obtain power utilizing information IFO1 (IFO2) of the electronic apparatus 910 (920). Then, in step S440, the power utilizing information IFO1 (IFO2) is compared with corresponding reference information IFR1 (IFR2) by the processing module 124 to determine an operating status of the electronic apparatus 910 (920). Alternatively, the power utilizing information IFO1 (IFO2) of the electronic apparatus 910 (920) is transmitted to the remote apparatus 140 by the processing module 124, and the power utilizing information IFO1 (IFO2) is compared with the corresponding reference information IFR1 (IFR2) by the remote apparatus 140 to determine the operating status of the electronic apparatus 910 (920).

Details of the step of determining, by the processing module 124, the operating status of the electronic apparatus 910 (920) by comparing the power utilizing information IFO1 (IFO2) with the reference information IFR1 (IFR2) in step S440 of FIG. 4 will be described below. Referring to FIG. 1, FIG. 3, FIG. 4, and FIG. 5, FIG. 5 is a flowchart illustrating detailed steps of step S440 and subsequent steps according to an embodiment of the invention. Step S440 includes detailed steps S541, S542 and S543. First, in step S541, whether a difference between the power utilizing information IFO1 (IFO2) and the corresponding reference information IFR1 (IFR2) is greater than a threshold value is determined by the processing module 124. If the determination result in step S541 is negative, the processing module 124 determines that the operating status of the electronic apparatus 910 (920) is normal, and the timer circuit 326 is disabled by the processing module 124 to prevent the timer circuit 326 from generating a reboot signal SRB, as shown in step S542. Conversely, if the determination result in step S541 is affirmative, the processing module 124 determines that the operating status of the electronic apparatus 910 (920) is abnormal, and abnormality information is transmitted to the remote apparatus 140 by the processing module 124, as shown in step S543.

Next, in step S550, whether to reset the electronic apparatus 910 (920) is determined by the remote apparatus 140 according to the abnormality information. If the determination result in step S550 is negative (namely, the remote apparatus 140 determines that the operating status of the electronic apparatus 910 (920) is not abnormal and determines not to reset the electronic apparatus 910 (920)), then the remote apparatus 140 notifies the processing module 124 to disable the timer circuit 326 to prevent the timer circuit 326 from generating the reboot signal SRB, as shown in step S560.

It is noted that when a manager of the remote apparatus 140 increases or decreases the number of the electronic apparatuses 910 (920) coupled to output terminals of the switching circuits 122_1 (122_2), an output current of the output power PO1 (PO2) will be increased or decreased, such that the difference between the power utilizing information IFO1 (IFO2) detected by the power measurement module 123 and the reference information IFR1 (IFR2) is greater than the threshold value. In that case, even though the processing module 124 determines that the operating status of the electronic apparatus 910 (920) is abnormal, the manager of the remote apparatus 140 can still determine that the operating status of the electronic apparatus 910 (920) is actually not abnormal and can then decide not to reset the electronic apparatus 910 (920).

Conversely, if the determination result in step S550 is affirmative (namely, the remote apparatus 140 determines that the operating status of the electronic apparatus 910 (920) is indeed abnormal and determines to reset the electronic apparatus 910 (920)), then reset information is transmitted to the processing module 124 by the remote apparatus 140, as shown in step S570. Then, the corresponding switching circuit 122_1 (122_2) is disconnected and re-connected by the processing module 124 according to the reset information to reset the electronic apparatus 910 (920), and the timer circuit 326 is disabled by the processing module 124 to prevent the timer circuit 326 from generating the reboot signal SRB, as shown in step S580.

Details of the step of determining, by the remote apparatus 140, the operating status of the electronic apparatus 910 (920) by comparing the power utilizing information IFO1 (IFO2) with the reference information IFR1 (IFR2) in step S440 of FIG. 4 will be described below. Referring to FIG. 1, FIG. 3, FIG. 4, and FIG. 6, FIG. 6 is a flowchart illustrating detailed steps of step S440 and subsequent steps according to another embodiment of the invention. Step S440 includes detailed steps S641, S642, S643, S644. First, in step S641, the power utilizing information IFO1 (IFO2) of the electronic apparatus 910 (920) is transmitted to the remote apparatus 140 by the processing module 124. Next, in step S642, whether a difference between the power utilizing information IFO1 (IFO2) and the corresponding reference information IFR1 (IFR2) is greater than a threshold value is determined by the remote apparatus 140. If the determination result in step S642 is negative, the remote apparatus 140 determines that the operating status of the electronic apparatus 910 (920) is normal, and the remote apparatus 140 notifies the processing module 124 to disable the timer circuit 326 to prevent the timer circuit 326 from generating a reboot signal SRB, as shown in step S643. Conversely, if the determination result in step S642 is affirmative, whether to reset the electronic apparatus 910 (920) is determined by the remote apparatus 140, as shown in step S644.

If the determination result in step S644 is negative (namely, the remote apparatus 140 determines that the operating status of the electronic apparatus 910 (920) is actually not abnormal and determines not to reset the electronic apparatus 910 (920)), proceeding to step S643, the remote apparatus 140 notifies the processing module 124 to disable the timer circuit 326 to prevent the timer circuit 326 from generating the reboot signal SRB.

Conversely, if the determination result in step S644 is affirmative (namely, the remote apparatus 140 determines that the operating status of the electronic apparatus 910 (920) is indeed abnormal and determines to reset the electronic apparatus 910 (920)), then reset information is transmitted to the processing module 124 by the remote apparatus 140, as shown in step S650. Then, the corresponding switching circuit 122_1 (122_2) is disconnected and re-connected by the processing module 124 according to the reset information to reset the electronic apparatus 910 (920), and the timer circuit 326 is disabled by the processing module 124 to prevent the timer circuit 326 from generating the reboot signal SRB, as shown in step S660.

The case where abnormality occurs in the communication module 125 in step S440 of FIG. 4 will be described below. Referring to FIG. 1, FIG. 3, FIG. 4, and FIG. 7, FIG. 7 is a flowchart illustrating detailed steps of step S440 and subsequent steps according to yet another embodiment of the invention. Step S440 includes detailed steps S741, S742, S743. First, in step S741, whether a difference between the power utilizing information IFO1 (IFO2) and the corresponding reference information IFR1 (IFR2) is greater than a threshold value is determined by the processing module 124. If the determination result in step S741 is negative, the processing module 124 determines that the operating status of the electronic apparatus 910 (920) is normal, and the timer circuit 326 is disabled by the processing module 124 to prevent the timer circuit 326 from generating a reboot signal SRB, as shown in step S742. Conversely, if the determination result in step S741 is affirmative, the processing module 124 determines that the operating status of the electronic apparatus 910 (920) is abnormal, but the processing module 124 cannot transmit abnormality information to the remote apparatus 140 via the abnormal communication module 125, as shown in step S743. Specifically, when abnormality occurs in the communication module 125, the abnormality information cannot be transmitted to the remote apparatus 140, so that the processing module 124 cannot receive a response from the remote apparatus 140 to disable the timer circuit 326.
