Grip enables the first network powered switch to support the protocol. Therefore, the first network power supply and receiving switch starts to provide power.

Figure 7 is a schematic diagram of the second embodiment of the first relay module of the present invention. Referring to Figure 7, the following describes a second embodiment of the first relay module 44, which corresponds to a simplified network management switch. The difference between the simplified network management type and the fully network management type is that the simplified network management type does not switch the routing part of network data, so the number of ports in the first media access control chip 50 is smaller, resulting in a smaller number of relays.

Figure 8 is a schematic diagram of the third embodiment of the first relay module of the present invention. Please refer to Figure 8. The following describes a third embodiment of the first relay module 44, which corresponds to a pure power switch. Compared with the simplified network management type, the pure power type does not retain the design of the first media access control chip 50 and only retains the power switching relay, so the second electrical transmission interface 42 is implemented with an RJ45 connector.

Figure 9 is a schematic diagram of the first embodiment of the second relay module of the present invention. Please refer to Figure 9. The following describes a first embodiment of the second relay module 66, which corresponds to a fully managed switch. The second media access control chip 76 includes a first port P1' and a second port P2'. Four pairs of twisted pairs connect the first port P1' and the second port P2'. The second relay module 66 includes a first relay 661 , the second relay 662, the third relay 663, the fourth relay 664, the fifth relay 665, the sixth relay 666, the first transformer 667 and the second transformer 668. The first relay 661, the second relay 662, the third relay 663 and the fourth relay 664 are used to transmit network data, and the fifth relay 665 and the sixth relay 666 are used to transmit the second DC voltage or the third DC voltage. The first relay 661, the second relay 662, the third relay 663 and the fourth relay 664 are all logically and physically switched by the second processor 74 according to the connection (Link up) and disconnection (Link down) of the line. The fifth relay 665 and the sixth relay 666 are both physically switched by the second processor 74 according to the power conditions of the first network power supply and reception switch and the second network power supply and reception switch, that is, whether there is voltage or current.

On the data stream, the first port P1' and the second port P2' of the second media access control chip 76 are used to detect the connection mode and switch according to the mode, and also through the fifth relay 665 and the third port P2'. Six relays 666 switch on the power supply, and cooperate with the action of the second power receiving module 70 or the second power supply module 78 to receive power or supply power with the first network power supply and receiving switch. In the design using coaxial cable, the number of relays used for network data can be reduced to one pair, which is not explained here.

Figure 10 is a schematic diagram of the second embodiment of the second relay module of the present invention. Please refer to Figure 10. The following describes a second embodiment of the second relay module 44, which corresponds to a simplified network management switch. The difference between the simplified network management type and the fully network management type is that the simplified network management type does not switch the routing part of network data, so the number of ports in the second media access control chip 76 is smaller, resulting in a smaller number of relays.

Using a fully network-managed first network power supply and reception switch and a second network power supply and reception switch, with the switching of the first port and the second port, users can have a nearly disconnection-free method, which is suitable for monitoring field. As shown in Table 1 and Figure 6, taking the first network power supply and receiving switch as an example, a more accurate switching is performed under a mechanism in which all interfaces are readable and configurable by the first processor 48. first processor The first power receiving module First power supply module The first port/second port of the first media access control chip The first relay module Read messages (Get) Live connection status Real-time power supply situation, that is, whether power is currently supplied, such as whether there is supply voltage or supply current Real-time connection status (whether there is any disconnection or reconnection) The control (DO) potential of the processor, pull high (pull high) or pull low (pull low), is the current state. Set command (Set) - on/off on/off Switching between loops (pull high or pull low) achieve purpose Since the potential of the renewable energy of the second network power supply and receiving switch is higher than the power supply value, the second network power supply and receiving switch is set to the power supply mode. The first network supply and receiving switch receives power from the second network supply and receiving switch in the power receiving mode. Since the potential of the regenerative energy of the second network power supply and reception exchanger is insufficient, the second network power supply and reception exchanger is set to the power receiving mode. The first network power supply and reception switch starts to supply power to the second network power supply and reception switch in the power supply mode. Since the second network power supply and receiving switch notifies the mode change by using the connection port Link down, the first processor uses the switching of the first relay, the second relay, the third relay and the fourth relay when receiving the change. Adjust to another always-on line to reduce break handling time The data line is quickly switched between the first port and the second port. The power line is quickly switched between the first power receiving module and the first power supply module. Table I

The fully managed network will use the link up and link down mechanism of the data port to quickly return power to the first network power supply and reception switch or to the second network power supply and reception switch. Therefore, the design requires the use of two data ports and more relays. The advantage is that the overall delay in electronic signal transmission between the first network power supply and reception switch and the second network power supply and reception switch is smaller.

When using a simplified network management type first network supply and receiving switch and a second network supplying and receiving switch, or using a simplified network management type second network supply and receiving switch plus a pure power type first network supply and receiving switch. The use of powered switches has its regulatory restrictions.

The operation switching rules of the simplified network management type first network power supply and reception switch and the second network power supply and reception switch are as shown in Table 2: The first network power supply and reception switch Second network power supply and reception switch Initial state, that is, rule 1: It is detected that the connection port is Link down, so the first processor turns on the power receiving mode and turns off the power supply mode. Initial state, that is, rule 1: It is detected that the connection port is Link down, so the second processor turns on the power receiving mode and turns off the power supply mode. Recover power and recharge mains power, that is, rule 2: The connection port is Link up, and it is detected that the power receiving line has voltage, so it is in power receiving mode at this time, and continuously monitors whether the second network power supply and receiving switch is Link down or has no voltage. The renewable energy availability state is first disconnected and then restored, that is, rule 2: The connection port is Link up, and it is detected that the renewable energy has power supply voltage, so the second processor first sets Link down, then sets Link up, and the second Processor turns on power mode After recharging, it is found that the connection is disconnected and the power supply state is switched back, that is, rule 3: The connection port is Link up, and it is detected that the power receiving line has no voltage, so the first processor turns on the power supply mode and continuously monitors whether there is Link down or whether there is a power receiving module. respond Rule 3: The connection port is Link up, and it is detected that the regenerative energy cannot provide power, so the second processor turns off the power supply mode, sets Link down first, and then sets Link up, and the second processor turns on the power receiving mode. The power supply is found to be disconnected or has no load, so it switches back to the initial state, that is, Rule 4. The connection port is Link up. It is detected that the first power supply module has no load, so the first processor turns off the power supply mode and turns on the power receiving mode. Table II

The operation design rules of the pure power-type first network power supply and reception switch and the simplified network management type second network power supply and reception switch are as shown in Table 3: The first network power supply and reception switch Second network power supply and reception switch Initial state, that is, rule 1: The first processor turns on the power receiving mode and turns off the power supply mode. Initial state, that is, rule 1: The second processor turns on the power receiving mode and turns off the power supply mode. Listening state, that is, rule 2: In the state where the power receiving mode has not successfully handed over to the second power supply module of the second network power supply and receiving switch, proceed: The first processor turns on the power supply mode and waits for a few seconds. If the power receiving module of the second network power supply and receiving switch cannot be handed over, jump back to rule 1 and successfully execute rule 4. Renewable energy availability state, that is, rule 2: When the renewable energy has power supply voltage, the second processor turns on the power supply mode. If the handshake is successful, the power supply will start, otherwise it will return to rule 1. Continue to monitor renewable energy until it is no longer able to provide power, and return to Rule 1 Recover power and recharge mains power, that is, Rule 3: When the handover is successful and voltage is detected on the receiving line, enter the power receiving mode and continuously monitor whether there is a network power outage. If there is a power outage, enter the listening state of Rule 2 Renewable energy unavailable state, that is, rule 3: When renewable energy cannot provide power, the second processor turns off the power supply mode, turns on the power receiving mode, and continues to monitor the renewable energy until it can provide power. Power supply status, that is, rule 4: If the handover is successful, detect that the second powered module of the second network power supply and receiving switch receives power and enters the power supply mode, and continuously monitors whether there is a network power outage. If there is a power outage, return Rule 1 Table 3

The first network power supply and reception switch uses a pure power supply type and the second network power supply and reception switch uses a simplified network management type connection method to avoid the need for the first network power supply and reception switch and the second network power supply and reception switch. There will be the possibility or possibility of being powered by the network at the same time, so a design with a light signal plus a switching waiting time can be used, and the same purpose can still be achieved after physical connection, which is a lower-cost design. Since the pure power-type first network power supply and reception switch does not have a media access control chip, the first processor cannot obtain the Link up/down signal, so it cannot be used together. The matching of the first network power supply and reception switch and the second network power supply and reception switch is shown in Table 4: The first network power supply and reception switch Second network power supply and reception switch Full network management Simplified network management type Full network management Can be matched with Can be matched with Simplified network management type Not matchable Can be matched with Pure power type Not matchable Can be matched with Table 4
