[Prior Art] [0002] In recent years, the technology of Power ,Ver Ethernet (P0E) is accelerating, and the Ethernet power supply technology can use an Ethernet route to transmit data and power. When using Ethernet power supply technology, the power supply equipment can be connected to a large number of powered s, such as a network camera. The system erector can freely place the Ge electric device in the desired position, regardless of whether there is a power outlet nearby or a separate power cord to connect the powered device, which can greatly reduce the cost of additionally providing the power line of the power receiving device. 'But because the Ethernet power supply technology cannot detect whether the power receiving device is down or the power receiving device is in an unresponsive state due to other factors, it cannot be used unless someone is present or remotely operating the powered device. Do the troubleshooting of immediacy, which leads to the lack of use. SUMMARY OF THE INVENTION [0003] The conventional Ethernet power supply technology utilizes a circuit loop generated when a power receiving device is connected to an Ethernet route to detect whether the power receiving device is connected to the power receiving device. Whether the device is shut down or faulty is detected. Therefore, the object of the present invention is to provide a fault recovery method for a network power supply system, which continuously transmits a detection signal to a power receiving device by using a power supply device. 'When the power receiving device cannot return a reply signal according to the 6-Hai detection signal, the power supply device stops. Supply the 09811506^single number A0101 Page 3 of 17 page 1013334879-0 1376118 _: On September 3, 101, the replacement page power supply is corrected, and the power of the power receiving device is re-provided after a waiting time to exclude the power. The problem of the failure of the power receiving device. In order to achieve the above object, the present invention provides a network power supply system, and a method for fault recovery, comprising the steps of: transmitting and transmitting power to a power receiving device via a power supply device. Passing the network transmission line via the power supply device - transmitting a detection signal to the power receiving device. When the power supply device does not receive the reply signal from the power receiving device for a set time, the power supply device stops transmitting power to the power receiving device. Finally, power is again transmitted to the power receiving device via the power supply device to restore the operation of the power receiving device. In order to achieve the above object, the present invention further provides a method for fault recovery of a network power supply system, comprising the steps of: transmitting power to a secondary power supply device of a power receiving device via a power transmission device via a power transmission line. After receiving the power, the secondary power supply device transmits the power through a power line to the power receiving device via the power transmission device to transmit a detection signal to the secondary power supply device of the power receiving device. After receiving the detection signal, the power supply device transmits the detection signal to the power receiving device via a signal transmission line. When the power supply device does not receive the reply signal of the power receiving device reply for a set time, the power supply device stops transmitting power to the power receiving device. Finally, power is again transmitted to the power receiving device via the power supply device to restore the operation of the secondary power receiving device. In summary, the method for fault recovery of the network power supply system of the present invention sends a detection signal to the power receiving device. Since the power receiving device needs to be in a normal operating state, the detection signal can be processed, and then a reply is sent according to the detection signal. Signal. Therefore, the power supply device can instantly detect whether the power receiving device is in a crash state or a fault state.

September 03 correction replacement page [0004] In addition, when the power supply device cannot receive the reply signal, it can stop transmitting power to the power receiving device. And transmitting power to the power receiving device again after a waiting time, whereby the power receiving device is restarted to exclude the down state or the fault state of the power receiving device. Therefore, the present invention does not require the presence of a person to monitor or use the power receiving device at the far end or the end, and can immediately eliminate the failure state of the power receiving device or cause the power receiving device to be in an unresponsive state due to other factors. The advantages and spirit of the present invention can be understood from the following detailed description of the invention and the accompanying drawings. [Embodiment] Please refer to the first figure, which is a system architecture diagram of a first embodiment of the network power supply system of the present invention. The network power supply system 1000 includes a power source device (PSE) and a plurality of power devices (PD).

The power supply device 100 can include a main network module 110, a power module 120, and a network power supply module 130. The main network module 110 can be coupled to a network such as the Internet 11 (indicated in the first figure) or a regional network to transmit data to the power receiving device 200 through the network. The power module 120 can receive the power P1 to supply the power supply device 100 itself and the power P1 required by the power receiving device 20 0. The network is for 09811506# single number deletion 1 page 5 / Π page 1013334879-0 1376118 September 03, 2003 shuttle replacement page power module 1 3 0 can be coupled to the main network module 丨丨The power module 120' can be connected to a plurality of network transmission lines li. The network power supply module 13 can receive the data and power P1 transmitted by the main network module 11 and the power module 12, respectively, and transmit the data and power P1 to the power receiving device through the network transmission line L1. 200. The power receiving device 200 can be a power receiving device 200 with network communication function. It can be an IP camera, a Volp phone, and a wireless network base station (Wireless ap). A device such as a microwave access device (WiMAX), but not limited to the above device. The power receiving device 200 can include a power receiving path module 21 and a processing module 220. The power grid module 210 is used to connect the network transmission line u to receive power pi and data from the network transmission line L1. The processing module 220 is coupled to the power grid module 21A and configured to receive and process the data from the power grid module 210. The processing module 2 can be composed of a central processing unit (CPU) and its associated circuits and chips, and can be designed differently for the type and function of the power receiving device 200. The processing module 200 can be a The prior art is not the focus of the present invention and will not be described here. Referring to the second figure, a flow chart of the first embodiment of the method for failing over the network of the invention network power supply line can be implemented by the following steps. The following components are referred to the first figure. First, the user can connect the power receiving device to the network transmission line u to be coupled to the power supply device 1 and turn on the power of the power receiving device. At this time, according to the technology of power P1 in Ethernet (P〇wer_ 〇ver Ethernet, POE), the power supply device 1〇〇_5〇6# single number A〇i01 a R ^ will pass through... Page 6/ Total 17 pages 1013334879-0 丄(10)118 [ϊοι^.09^ 〇3Tto^r The transmission line LI generates a detection voltage to detect the reception; the device 2 is connected to the network transmission line L1 and controlled The network power supply module 130 provides the power p required for the power receiving unit 200 (step sl1). In order to detect whether the power receiving device 200 is operating normally, the power transmitting device 1 transmits a detection signal to the power receiving device 20 through the network transmission line L1, and the detection signal can be a network packet such as an ARp/RARp packet or a 1CMP. Packet (step S103). In this embodiment, the detection signal can be a network packet, and the power receiving device 200 must be in a normal operating state after receiving the detection signal to start the processing module 220 to parse the detection signal. And replying to the power supply device 1 according to the detection signal, the reply information may also be a network packet, such as an ARP/RARp packet or an ICMP packet in the prior art. Therefore, after the power supply device 1 transmits a detection signal to the power receiving device 2, it determines whether a response signal corresponding to the detection signal is received. If the power receiving device 200 receives the detection signal, it responds with a reply signal. In the power supply device 100, if the power receiving device 200 is in a normal operating state, the step 103 can be skipped after a predetermined time, so that the power supply device 100 continuously detects whether the power receiving device 2 is in a normal operation. The state 'this predetermined time may be a short time such as 1 millisecond (step S105). When the power supply device 100 does not receive the reply signal of the power receiving device 200 after a set time, it may represent that the power supply device 100 is in a fault state. At this time, the power supply device 100 stops transmitting the power P1 to the power receiving device 200' to stop the power receiving device 200, and the set time may be a short time such as 1 to 3 seconds (step S107). After a waiting time, the power P1 is again transmitted via the power supply device 100 at 09811506#.Single number A〇l〇l Page 7/Total 17 Page 1013334879-0 1376118 _: September 03, 2011 Press the replacement page The power receiving device 200 restores the operation of the power receiving device 200, and the waiting time is set to 5 to 15 seconds. Since the power receiving device 200 is restarted, the cause of the failure of most of the power receiving device 200 can be eliminated, and the power receiving device 200 should be able to return to a normal operating state. In addition, since the power receiving device 200 receives the power P1 and needs to start up after the startup is completed, the startup time may be 10 to 300 seconds, and the startup time varies according to different power receiving devices 200. Therefore, after the startup time, the power supply device 100 can transmit a detection signal to the power receiving device 200 again in step S103 to detect whether the failure of the power receiving device 200 is excluded (step S109). If the above manner fails to restore the power receiving device 200 to a normal operating state, the power supply device 100 can determine that the power supply device 100 sends a notification information to the management after the power supply device 100 retransmits the power P1 for a predetermined number of times. Personnel, the notification information can be a mobile phone newsletter or an email. Please refer to the third figure, which is a system architecture diagram of a second embodiment of the network power supply system of the present invention. The difference from the first embodiment is that the power receiving device 200a includes the primary power supply device 300 and the primary power receiving device 400. The power supply device 300 is connected to the network transmission line L1, and the power P1 and data transmitted by the network transmission line L1 are transmitted through a power line through the network power processing module 310 included in the power supply device 300. The L2 is transmitted with a signal transmission line L3, and the signal transmission line L3 can be an Ethernet route. The power receiving device 400 can be a network camera, a network telephone, a wireless network base station, and a global interoperable microwave access device. The power receiving device 400 includes a power receiving module 410, a network module 420' and a processing sink 150# single number A0101 page 8 / total 17 pages 1013334879-0 ip j -. 101 years.09 month = 3Q. The power receiving module 4iQ receives the power line -1, and the network module is configured to receive the rounded <> material of the signal transmission line L3. Refer to the fourth page for the network of the present invention for the "failure method of the system". The following component numbers refer to the third figure and differ from the first embodiment in that a power supply device 100 is provided. The power P1 is transmitted to the secondary power supply device 300 of the power receiving device 200 through the network transmission line L1 (step S201). After the power supply device 100 receives the power P1, the power pl is transmitted through the power line L2 to the secondary power receiving device 400. (Step S203). A power supply device 300 transmits a detection signal to the secondary power supply device 300 of the power receiving device 200 via the network transmission line L1 (step S205). After the power supply device 300 receives the detection signal, the signal is transmitted via a signal. The wheel line L3 is transmitted to the power receiving device 400 (step S207). The power supply device 100 determines whether a reply signal is received. When the power supply device 100 receives the reply signal, the process returns to step S207 (step S209). When the power supply device 100 does not receive the reply signal of the power receiving device 400 for a set time, the power supply device stops transmitting the power P1 to the power receiving device 200 (step S211). * The power P1 is again transmitted to the power receiving device 200 via the power supply device 100 to restore the operation of the secondary power receiving device 400. After a startup time, the process returns to step S207 to continue detecting the power receiving device 200 (step S213). The first embodiment 'If the above method cannot make the secondary power receiving device 400 09811506 a single number A0101 page 9 / a total of 17 pages 1013334879-0 1376118 _: September 03, 2003 shuttle replacement page is restored to a normal operating state After the power supply device 100 retransmits the power P1 for a predetermined number of times, the power supply device 100 can send a notification information to the administrator via the power supply device 100. In summary, the network power supply system 100 0 of the present invention. The fault recovery method is to send a detection signal to the power receiving device 200. Since the power receiving device 200 needs to be in a normal operating state, the detection signal can be processed, and then a reply signal is sent according to the detection signal. Therefore, the power supply device 100 can immediately detect Detecting whether the power-on device 200 is in a crash state or a fault state. In addition, when the power supply device 100 cannot receive the reply signal, The power P1 can be stopped from being transmitted to the power receiving device 200, and the power P1 can be transmitted again to the power receiving device 200 after a waiting time, whereby the power receiving device 200 is restarted to exclude the power receiving device 200 from being down or due to other factors. The fault condition of the power receiving device is caused to be in an unresponsive state. Therefore, the present invention does not require personnel to be present in the field to monitor or use the power receiving device 200, and can immediately eliminate the crash or fault state of the power receiving device 200. With the above preferred embodiment The detailed description of the present invention is intended to be illustrative of the nature of the invention.
