Embodiment one

The networking device 1 may include a network transmission interface 11 , an electronic switch module 13 , a control module 15 , a main power supply 16 , a backup power supply 18 and a detection module 19 . Wherein the electronic switch module 13 is coupled between the network transmission interface 11 and the control module 15, the standby power supply 18 is coupled to the electronic switch module 13, the detection module 19 is coupled to the main power supply 16 and the electronic switch module 13, and the main power supply 16 provides The power required for a networked device to function properly.

The network transmission interface 11 further includes a first network port 111 , a first isolation transformer 113 , a second network port 115 and a second isolation transformer 117 . The first isolation transformer 113 is coupled between the first network port 111 and the electronic switch module 13 , and the second isolation transformer 117 is coupled between the second network port 115 and the electronic switch module 13 . The first network port 111 and the second network port 115 may be RJ-45 network connectors, but the present invention is not limited thereto.

The electronic switch module 13 includes a first electronic switch 131 and a second electronic switch 133 . The first electronic switch 131 is coupled between the first isolation transformer 113 and the control module 15 . The second electronic switch 133 is coupled between the second isolation transformer 117 and the control module 15 . Furthermore, the first electronic switch 131 includes a first terminal T1 , a second terminal T2 and a third terminal T3 , and the first terminal T1 can be selectively connected to the terminal T2 or T3 . The second electronic switch 133 includes a first terminal T4, a second terminal T5, and a third terminal T6. The first terminal T4 can be selectively connected to the terminal T5 or T6, and the third terminal T3 is connected to the third terminal T6. are mutually coupled.

When the first terminal T1 and the second terminal T2 of the first electronic switch 131 are turned on, the first electronic switch 131 can provide a first path as a transmission path between the first isolation transformer 113 and the control module 15 . Similarly, when the first terminal T4 and the second terminal T5 of the second electronic switch 133 are turned on, the second electronic switch 133 can provide a first path to be used as a transmission path between the second isolation transformer 117 and the control module 15 .

In addition, when the first terminal T1 and the second terminal T3 of the first electronic switch 131 are turned on and the first terminal T4 and the second terminal T6 of the second electronic switch 133 are turned on, the first electronic switch 131 and the second The electronic switches 133 respectively provide the second paths. And because the third terminal T3 and the third terminal T6 are coupled to each other, the first isolation transformer 113 and the second isolation transformer 117 can transmit signals through the second path provided inside the electronic switch module 13 . In other words, a transmission path can be established between the first isolation transformer 113 and the second isolation transformer 117 by bypassing the signal provided by the electronic switch module 13 .

In this embodiment, both the first electronic switch 131 and the second electronic switch 133 of the electronic switch module 13 switch to provide the first path or the second path according to whether a switching signal is received or not. Specifically, when the electronic switch module 13 receives the switching signal, the first electronic switch 131 and the second electronic switch 133 are switched on to the first path by default, and when the electronic switch module 13 does not receive the switching signal, the first The electronic switch 131 and the second electronic switch 133 are switched and conducted to the second path. In actual operation, the electronic switch module 13 can be an electronic multiplexer, and the switch control mode of the electronic switch module 13 can be designed according to actual operation requirements. The utility model is not limited to the illustrations of the above-mentioned embodiments.

The control module 15 is the control core of the network connection device 1, and the control module 15 can perform a predetermined task according to the network signal transmitted by the first network port 111 and/or the second network port 115. The predetermined work can be viewed as the work of the network connection device 1 adjusted as needed. Furthermore, as far as the common knowledge in the art is concerned, the control module 15 may include a controller or other relevant circuit components required to perform network signal processing, so details will not be described here.

The detection module 19 can detect the power supply state of the main power supply 16 to know whether the main power supply 16 is normal or abnormal (for example, the mains power is cut off). When the detection result is normally powered by the main power supply 16, the detection module 19 outputs a switching signal to the electronic switch module 13, so that the electronic switch module 13 is switched to transmit signals through the first path, and now the control module 15 can pass through the first electronic switch. 131 . The first isolation transformer 113 transmits network signals with the first network port 111 . Similarly, the control module 15 can transmit network signals with the second network port 115 through the second electronic switch 133 and the second isolation transformer 117 .

In addition, when the main power supply 16 stops supplying power due to power failure, the detection module 19 has no power supply, so the detection module 19 cannot output the switch signal to the electronic switch module 13 . When the electronic switch module 13 does not receive the switching signal output by the detection module 19 , the electronic switch module 15 will switch to transmit signals via the second path.

It should be noted that the backup power supply 18 provided in this embodiment can continue to provide power supply to the electronic switch module 13 when the main power supply 16 fails, so as to ensure that the operation of the electronic switch module 13 is not affected by the power supply stoppage of the main power supply 16 . Furthermore, in practice, the backup power source 18 can be a battery, for example, a primary battery or a secondary battery.

Therefore, in this embodiment, since the utility model replaces the traditionally used relays with the electronic switch module 13, the electronic switch module 13 has the characteristics of small size and does not take up space, so that the overall product design of the networking device 1 can be closer to miniaturization. Furthermore, the electronic switch module 13 is designed to be located between the first isolation transformer 113 , the second isolation transformer 117 and the control module 15 . The electronic switch module 13 provides the shielding effect of electrical isolation through the first isolation transformer 113 and the second isolation transformer 117, which will effectively prevent the first network port 111 and the second network port 115 from directly inputting a large voltage and causing damage to the electronic switch module 13. damage.

In addition, it should be noted that the number of network ports described in this embodiment is exemplified by two, but the utility model is not limited thereto, because the number of network ports can be adjusted according to the actual design requirements of the networking device 1, Moreover, the number of isolation transformers and electronic switches can also be adjusted correspondingly according to the number of network ports.

Embodiment two

Please refer to FIG. 2 . FIG. 2 is a schematic block diagram of Embodiment 2 of the network connection device with network switching of the present invention. Compared with the networking device 1 in FIG. 1, the networking device 2 described in this embodiment has a third electronic switch 135 and a charging module 17. In addition, the circuit structure of the networking device 2 described in this embodiment And the operation method is substantially the same as the aforementioned networking device 1 in FIG. 1 .

In this embodiment, the third electronic switch 135 is coupled between the first electronic switch 131 , the second electronic switch 133 and the detection module 19 . Furthermore, the third electronic switch 135 includes a first terminal T7 , a second terminal T8 and a third terminal T9 , and the first terminal T7 can be selectively connected to the terminal T8 or T9 . The first terminal T7 of the third electronic switch 135 is also coupled to the third terminal T3 of the first electronic switch 131, and the third terminal T9 of the third electronic switch 135 is also coupled to the third terminal T6 of the second electronic switch 133. connected, the output of the third terminal T9 of the third electronic switch 135 is floating.

Furthermore, a first path can be provided when the first terminal T7 and the second terminal T8 of the third electronic switch 135 are turned on, and when the first terminal T7 and the third terminal T9 of the third electronic switch 135 are turned on At this time, the third switch 135 can provide a second path to be used as a transmission path between the third terminal T3 of the first electronic switch 131 and the third terminal T6 of the second electronic switch 133 .

Specifically, in this embodiment, the electronic switch module 13 and the third electronic switch 135 relatively provide path switching of the first path or the second path according to whether a switching signal is received or not. When the third electronic switch 135 receives the switching signal, the first terminal T7 and the second terminal T8 are connected by default, and the third electronic switch 135 provides a first path for signal transmission. When the third electronic switch 135 does not receive the switching signal, the first terminal T7 and the third terminal T9 of the third electronic switch 135 are turned on, and the third electronic switch 135 provides a second path for signal transmission.

Therefore, when the detection module 19 detects that the power supply status of the main power supply 16 is normal, the detection module 19 outputs switching signals to the electronic switch module 13 and the third electronic switch 135 respectively. At this time, the control module 15 transmits network signals with the first network port 111 through the first electronic switch 131 and the first isolation transformer 113, and the same control module 15 can also communicate with the first network port 111 through the second electronic switch 133 and the second isolation transformer 117. The two network ports 115 transmit network signals.

And when the detection module 19 detects the abnormal situation that the main power supply 16 is powered off, the detection module 19 cannot work normally. Therefore, neither the electronic switch module 13 nor the third electronic switch 135 can receive the switching signal output by the detection module 19 . Therefore, under the power supply of the backup power supply 18, the electronic switch module 13 and the third electronic switch 135 will respectively switch to the second path to transmit signals, so that the first isolation transformer 113 and the second isolation transformer 117 can pass through the electronic switch module 13 and the second path. The second paths respectively provided by the three electronic switches 135 communicate with each other. In other words, the network signal input to the first network port 111 is transmitted to the second network port 115 by bypassing the signal of the second path provided by the electronic switch module 13 and the third electronic switch 115 .

It is worth noting that the third electronic switch 135 used in this embodiment can effectively reduce signal mistransmission. For example, when the electronic switch module 13 and the third electronic switch 135 are switched to transmit data in the first path, because the network signal is a high-frequency signal, there may still be a small amount of signal transmitted through the second path of the electronic switch module 13, but through the second path of the electronic switch module 13. The third electronic switch 135 provides an additional electrical isolation function for signal transmission, thereby effectively reducing the above-mentioned mistransmission of signals. In addition, for those skilled in the art, the number of the third electronic switch 135 can be set according to actual needs, so as to increase the stability of the internal signal transmission of the networking device 2 .

In addition, the charging module 17 described in this embodiment is coupled between the main power source 16 and the backup power source 18 . When the power supply of the main power supply 16 is normal, the charging module 17 can obtain a charging power from the main power supply 16 , and the charging module 17 can use the charging power to charge the rechargeable battery in the standby power supply 18 .

Embodiment Three

Please refer to FIG. 3 . FIG. 3 is a schematic block diagram of a network connection device according to a third embodiment of network switching of the present invention. The detection method of the detection module 19 of the networking device 3 described in this embodiment is different from the detection method of the detection module 19 of the networking device 1 in FIG. 1 . In addition, the networking device 3 described in this embodiment The circuit structure and operation method are substantially the same as the aforementioned networking device 1 in FIG. 1 .

The detection module 19 is coupled to the electronic switch module 13 and the control module 15 , and the detection module 19 detects whether the working condition of the control module 15 is abnormal. For example detection module 19 can detect whether the controller or the microprocessor in the control module 15 is dead, when the controller or the microprocessor is not dead, the detection module 19 finds that the working condition of the control module 15 is normal now, and the detection module 19 The switching signal will be output to the electronic switch module 13 . And when the internal controller or microprocessor of the control module 15 crashes, the detection module 19 determines that the working condition of the control module 15 is abnormal, and the detection module 19 will stop outputting the switching signal to the electronic switch module 13 .

In another embodiment, the detection module 19 detects whether the signal transmitted by the control module 15 is abnormal. For example, when the signal transmitted externally by the control module 15 does not contain a large amount of meaningless blank packets or garbage packets, the detection module 19 determines that the working condition of the control module 15 is normal at this time, and the detection module 19 will output the switching signal to the electronic switch module. Conversely, when the signal transmitted externally by the control module 15 contains a large number of meaningless blank packets or garbage packets, the detection module 19 determines that the working condition of the control module 15 is abnormal at this time, and the detection module 19 will stop outputting switching signals to the electronic switch Module 13.

In addition, how the detection module 19 detects whether the controller or the microprocessor in the control module 15 is dead, or how to detect whether the signal transmitted by the control module 15 is abnormal or not, all belong to those skilled in the art. Known technology, so it will not be described in detail here.

It should be noted that the above mentioned embodiments can be used interchangeably. For example, the detection module 19 can simultaneously detect whether the main power supply 16 and the control module 15 are abnormal, and stop outputting the switching signal when one of them is abnormal.

To sum up, the network connection device provided by the utility model can know the working status of the network connection device through the detection module, and can use the signal bypass function provided by the electronic switch module when the main power supply or the control module is abnormal. In order to ensure that network signals can be smoothly transmitted through the network to the next-level network-related devices for use. In addition, the utility model can meet the demand for product miniaturization by using the electronic switch module,

The above descriptions are only examples of the present utility model, and are not intended to limit the protection scope of the present utility model.
