Description

Ethernet Power Switch System

The present invention relates to a switch system, in particular to an Ethernet power supply switch system.

Please refer to Figure 6, which is a schematic diagram of the known Ethernet power supply switch 2 connected to the terminal device T3. The Ethernet power supply (Power over Ethernet; PoE) switch 2 is a technology that can transmit power and data to the terminal device through the network cable in the Ethernet network at the same time. It can be widely used in terminal devices such as Internet phones, wireless base stations, Internet cameras, computers, etc. By transmitting network data through the network cable and providing power to the terminal device T3 at the same time, the terminal device can save the line configuration of additional power connection.

As mentioned above, since most of the existing terminal devices such as Internet phones, wireless base stations, Internet cameras, computers, etc. are 8-core network cable connection ports, and most of the current Internet of Things architectures using Internet Protocol (IP) are 8-core network cable connection ports, if you want to use terminal devices with 2-core network cable connection ports, you need to reconfigure the 8-core network cable into a 2-core network cable line to connect various terminal devices with 2-core network cable connection ports, which will consume time and cost to reconfigure the line.

Therefore, how to provide an Ethernet power supply switch system has become a topic that urgently needs to be studied.

In view of the above problems, the present invention provides an Ethernet power supply switch system, including a first Ethernet power supply switch. The first Ethernet power supply switch has a first power connection port, at least one Ethernet cable connection port, at least one first two-core transmission line connection output port, and a first line conversion chip. The first power connection port is connected to a first power source to receive a first power signal. At least one Ethernet cable connection port is connected to a router to receive a network signal. At least one first two-core transmission line connection output port is connected to a first terminal device. The first line conversion chip is connected to the first power connection port, at least one Ethernet connection port, and at least one first two-core transmission line connection output port, converts the first power signal and the network signal, and transmits the first power signal and the network signal to the first terminal device through at least one first two-core transmission line connection output port, wherein the first terminal device has a first two-core transmission line connection input port correspondingly connected to the first two-core transmission line connection output port.

As mentioned above, the new model can transmit signals and power through the first two-core transmission line connected to the output port, so it can customize and flexibly use the Ethernet power supply switch system to provide power signals and network signals at the same time without reconfiguring the original two-core line, thereby greatly saving the time and cost of users to reconfigure the line.

FIG1 is a block diagram of the first embodiment of the novel Ethernet power supply switch system; FIG2 is a block diagram of the second embodiment of the novel Ethernet power supply switch system; FIG3 is a block diagram of the third embodiment of the novel Ethernet power supply switch system; FIG4 is a block diagram of the first embodiment of the novel Ethernet power supply switch system including a switch; FIG5 is a block diagram of the second embodiment of the novel Ethernet power supply switch system including a switch; and FIG6 is a schematic diagram of a known Ethernet power supply switch connected to a terminal device.

Please refer to FIG. 1, which is a block diagram of the first embodiment of the novel Ethernet power supply switch system 1. In this embodiment, the Ethernet power supply switch system 1 includes a first Ethernet power supply switch 11, and the first Ethernet power supply switch 11 has a first power connection port 111, at least one Ethernet cable connection port 112, at least one first two-core transmission line connection output port 113, and a first line conversion chip 114. The first power connection port 111 is connected to the first power source P1 to receive the first power signal. At least one Ethernet cable connection port 112 is connected to the router R through the Ethernet cable to receive the network signal. The Ethernet cable includes a 4-core or 8-core line. At least one first two-core transmission line connection output port 113 is connected to the first terminal device T1. The first line conversion chip 114 is connected to the first power connection port 111, at least one Ethernet connection port 112 and at least one first two-core transmission line connection output port 113, converts the first power signal and the network signal, and transmits the first power signal and the network signal to the first terminal device T1 through at least one first two-core transmission line connection output port 113, wherein the first terminal device T1 has a first two-core transmission line connection input port T11, and is correspondingly connected to the first two-core transmission line connection output port 113 through a first two-core transmission line, wherein the first two-core transmission line is an RJ11 two-core transmission line.

As described in the previous technology, since the current network transmission cable is an 8-core transmission cable structure, when the Ethernet power supply switch 2 is connected to the terminal device T3 through the 8-core network transmission cable, it is limited by the transmission distance of the 8-core network transmission cable and can only be set with a length of 100 meters. Even if the network transmission speed is reduced, the 8-core network transmission cable can only be extended to a distance of 250 meters to achieve the function of providing power signals and network signals to the terminal device T3 at the same time. However, if the installation distance of the 8-core network transmission line cannot exceed 250 meters, the Ethernet power supply switch 2 with power supply network cannot be widely used in places where long-distance line configuration is required, such as high-rise community buildings.

In the embodiment of the present invention, the first Ethernet power supply switch 11 can be set at the user end or the remote end according to the user's needs. Furthermore, since the two-core transmission line can transmit network signals and power signals at the same time, it can provide power signals and network signals at the same time within the range allowed by the line configuration distance of the user end, and the line distance can reach more than 300 meters. If the user only needs to receive network signals, the transmission distance of the two-core transmission line can be extended to more than 1200 meters. Furthermore, since existing terminal equipment needs to meet the requirements of high-speed data transmission when using 8-core transmission lines to transmit data, the line configuration of 8-core transmission lines cannot achieve the purpose of long distance and high-speed data at the same time. In other words, the 8-core transmission line is limited by the requirement of high-speed data transmission, and the line configuration distance is shorter. In contrast, since the terminal equipment used in this case does not need to meet the requirements of high-speed data transmission, the network data transmission distance can be extended to more than 1,200 meters when using 2-core transmission lines.

Please refer to FIG. 2, which is a block diagram of the second embodiment of the novel Ethernet power supply switch system 1. In this embodiment, the Ethernet power supply switch system 1 further includes a second Ethernet power supply switch 12, and the second Ethernet power supply switch 12 has a second power connection port 121, at least one second two-core transmission line connection input port 122, at least one eight-core transmission line connection output port 123, and a second line conversion chip 124. The second power connection port 121 is connected to the second power source P2 to receive the second power signal. At least one second two-core transmission line connection input port 122 is connected to at least one first two-core transmission line connection output port 113 of the first Ethernet power supply switch 11 to receive network signals, wherein the first two-core transmission line connection output port 113 is connected to the second two-core transmission line connection input port 122 through a second two-core transmission line such as RJ11. At least one eight-core transmission line connection output port 123 is connected to the second terminal device T2. The second line conversion chip 124 is connected to the second power connection port 121, the at least one second two-core transmission line connection input port 122 and the at least one eight-core transmission line connection output port 123, converts the second power signal and the network signal, and transmits the second power signal and the network signal to the second terminal device T2 through the at least one eight-core transmission line connection output port 123. The second terminal device T2 has an eight-core transmission line connected to the input port T21, and is connected to the output port 123 via an eight-core transmission line, so as to receive the second power signal and the network signal.

Please refer to Figure 3, which is a block diagram of the third embodiment of the novel Ethernet power supply switch system 1. In this embodiment, the Ethernet power supply switch system 1 is the same as the second embodiment, and also includes a first Ethernet power supply switch 11 and a second Ethernet power supply switch 12. The only difference is that the second Ethernet power supply switch 12 in the third embodiment does not need to be externally connected to the second power source P2.

As mentioned above, in actual application, the first Ethernet power supply switch 11 is set at a remote end, and the second Ethernet power supply switch 12 is set at the user end. Furthermore, although the two-core transmission line can transmit network signals and power signals at the same time, its line distance can only reach more than 300 meters. Therefore, in the case of a community building or a high-rise building, the first Ethernet power supply switch 11 can be set in the basement, and the line is configured to the user's residence through the two-core transmission line to transmit the network signal to the second Ethernet power supply switch 12 set in the user's residence, and the network signal is transmitted to the second terminal device T2 through the second Ethernet power supply switch 12. Through this line configuration, as in the third embodiment described above, the transmission distance of the network signal can be extended to more than 1200 meters without providing the first power signal to the second Ethernet power supply switch 12 (installed in the user's residence). In addition, as in the second embodiment described above, the second terminal device T2 can still be connected to the second power source P2 through the second Ethernet power supply switch 12, and the second Ethernet power supply switch 12 provides the second power to the second terminal device T2.

In contrast, in today's community buildings, in order to provide both power signals and network signals, power signals may be concentrated on the same Ethernet power switch. In addition, this approach not only requires the power company to set up a dedicated line so that all power is concentrated on the same Ethernet power switch, but also greatly increases the electricity cost. Through the above-mentioned second embodiment, the power can be dispersed to the second Ethernet power switch 12 installed in each user's residence, to avoid the problem of power signal concentration, and further save the electricity bills of building users without setting up a power dedicated line.

Please refer to FIG. 4, which is a block diagram of the first embodiment of the novel Ethernet power supply switch system including a switch 115. In the first embodiment, the first Ethernet power supply switch 11 further includes a switch 115, which is disposed between the first two-core transmission line connection output port 113 and the first line conversion chip 114, and is electrically connected to the first line conversion chip 114, and is electrically connected or electrically disconnected from the first two-core transmission line connection output port 113 according to a control instruction of the first line conversion chip 114, so as to determine whether to transmit the first power signal of the first power source P1 to the first two-core transmission line connection output port 113, and transmit the first power signal to the first terminal device T1 through the two-core transmission line. Furthermore, in the first embodiment described above, although the first Ethernet power switch 11 can simultaneously transmit the first power signal and the network signal to the first terminal device T1, in other applications of the present invention, it can be determined whether to simultaneously transmit the first power signal and the network signal to the first terminal device T1 according to the switch 115 provided on the first Ethernet power switch 11.

As mentioned above, among the users in the community building, in order to avoid power concentration on the same first Ethernet power supply switch 11, the switch 115 can be switched to a mode that does not provide a power signal to the first terminal device T1, so as to extend the line configuration length of the two-core transmission line. For example, when extending the line length of the two-core transmission line, the first Ethernet power supply switch 11 can be set in the basement of the community building, and the configuration distance of the two-core transmission line can be extended to residents above the 30th floor. For apartment users, if there are not many residents in the apartment, the power consumption is not large, and the floor is not high, the switch 115 can be switched to a mode of simultaneously providing power signals and network signals to the first terminal device T1 when a two-core transmission line with a limited length is configured.

Please refer to FIG. 5, which is a block diagram of the second embodiment of the novel Ethernet power supply switch system including a switch 115. In the second embodiment, the first Ethernet power supply switch 11 further includes a switch 115, which is disposed between the first two-core transmission line connection output port 113 and the second two-core transmission line connection input port 122, and is electrically connected to the first two-core transmission line connection output port 113, and is electrically connected or electrically disconnected from the second two-core transmission line connection input port 122 according to a control instruction of the first line conversion chip 114, so as to determine whether to transmit the first power signal of the first power source P1 to the second two-core transmission line connection input port 122. Furthermore, in the second embodiment, the second Ethernet power switch 12 is the same as the first Ethernet power switch 11. Although both have a power connection port that can receive external power, in the second embodiment, if the first two-core transmission line connection output port 113 and the second two-core transmission line connection input port 122 are electrically connected through the switching switch 115, the first Ethernet power switch 11 and the second Ethernet power switch 12 can be regarded as a series structure, and the first Ethernet power switch 11 transmits the first power signal to the second Ethernet power switch 12. At this time, the second power connection port 121 of the second Ethernet power switch 12 does not need to be additionally connected to the second power source P2. If the switch 115 is not electrically connected to the second two-core transmission line connection input port 122, the second Ethernet power supply switch 12 can be connected to the second power source P2 through the original second power connection port 121.

In this new embodiment, the first terminal device T1 includes a 2-core Internet Protocol (IP) video phone, a 2-core IP video intercom, a 2-core IP video tablet intercom, and a 2-core IP access control device. The second terminal device T2 includes an 8-core Internet Protocol video phone, an 8-core IP video intercom, an 8-core IP video tablet intercom, and an 8-core IP access control device.

In summary, the present invention can customize and flexibly set up the Ethernet power supply switch system according to the connection port form of the terminal equipment, whether the terminal equipment needs to provide power signals and network signals at the same time, and the wiring distance requirements of the user's residence, so as to greatly save the time and cost of users to reconfigure the lines, and save the user's electricity bills and electricity consumption while avoiding power concentration.
