Description

TECHNICAL FIELD

[0001] The utility model relates to a node device and a circuit system using the node device, and particularly relates to a node device and a circuit system using the node device, which can have a multi-path transmission architecture. The multi-path transmission architecture can reduce the hop count required for transmitting a control signal to a node device as a destination device and can avoid a situation in which a node device receives an incorrect signal when one of the paths fails. BACKGROUND

[0002] In some applications, a circuit system is composed of a plurality of node devices electrically connected. For example, in the case of a light pole system, the node devices are light poles electrically connected to receive a control signal transmitted from a controller (used as a root device, which can be a group controller or a master controller) and display corresponding blessing information. In addition, the circuit system can also be a digital spirit card system, and the node devices can be digital spirit cards.

[0003] In the above applications, when a control signal is transmitted to a node device as a destination device, the strength of the control signal is greatly weakened (i.e., the driving ability is poor or the signal-to-noise ratio is too low) if the control signal passes through multiple intermediate node devices, resulting in the node device as the destination device being unable to perform the corresponding function according to the control signal. On the other hand, the prior art circuit system is mostly designed to have only one transmission path to the node device as the destination device. Therefore, if the transmission path fails due to a specific reason (e.g., a connection line is disconnected or an intermediate node device fails during transmission), the control signal cannot be successfully transmitted to the node device as the destination device.

[0004] Please refer to Figure 1 , Figure 1is a schematic block diagram of one of the prior art circuit systems. The circuit system 1 includes a root device 10 and a plurality of node devices 1101-1120. The plurality of node devices 1101-1120 are sequentially connected in series, i.e. the output port of the node device 1101 is electrically connected to the input port of the node device 1102 through a transmission line, the output port of the node device 1102 is electrically connected to the input port of the node device 1103 through a transmission line, and so on. The input port of the node device 1101 is electrically connected to the output port of the root device 10, and the output port of the node device 1120 is floating. In this transmission architecture, when the node device 1120 receives a control signal, the control signal has already passed through 19 hops (i.e. passed through the node devices 1101-1109), so the strength of the control signal to the node device 1120 can be greatly attenuated. Furthermore, if the transmission line between the node devices 1103 and 1104, for example, is broken, or if the node device 1110, for example, is faulty, the node device 1120 will not receive the control signal.

[0005] Please refer to Figure 2 , Figure 2 is a schematic block diagram of another prior art circuit system. The circuit system 1' includes a root device 10' and a plurality of node devices 1101-1120, wherein the plurality of output ports of the root device 10' are electrically connected to the plurality of input ports of the node devices 1101, 1106, 1111 and 1116 respectively, the plurality of node devices 1101-1105 are connected in series with each other, the plurality of node devices 1106-1110 are connected in series with each other, the plurality of node devices 1111-1115 are connected in series with each other, and the plurality of node devices 1116-1120 are connected in series with each other, so as to form a tree-shaped transmission architecture. Although this approach can reduce the number of hops of the control signal to the node device as the destination device, the design only has one transmission path to the node device as the destination device, so if the transmission path is disabled for a certain reason (e.g. the connection line is broken or the intermediate node device in the transmission process is faulty), the control signal will not be successfully transmitted to the node device as the destination device. Therefore, the industry still needs a circuit system and a node device which can reduce the number of hops and still transmit the control signal to the node device as the destination device when one of the paths is disabled.

[0043] The present application mainly provides a node device for constructing a circuit system of a multi-path transmission architecture. In the circuit system formed by a plurality of node devices, the node device as a destination device can have a multi-path transmission path, so as to avoid the situation that when one of the transmission paths fails, the control signal cannot be successfully transmitted to the node device as the destination device, and the number of intermediate node devices (i.e. the number of hops) required for the control signal to be transmitted to the node device as the destination device can be reduced. Further, the node device has a plurality of input ports and a plurality of output ports, or the node device includes at least four input / output ports. A plurality of node devices in one column are connected to each other, and a plurality of node devices in the same row are also connected to each other, so as to form the multi-path transmission architecture.

[0044] First, please refer to Figure 3 , Figure 3is a schematic block diagram of a circuit system of an embodiment of the present utility model. The circuit system 2 includes a root device 20 and multiple node devices 2101~2120. The node devices 2101~2105 of the first column are sequentially connected in series, that is, the output port of the node device 2101 is electrically connected to the input port of the node device 2102, the output port of the node device 2102 is electrically connected to the input port of the node device 2103, and the others are sequentially connected in series. The node devices 2106~2110 of the second column are sequentially connected in series, the node devices 2111~2115 of the third column are sequentially connected in series, and the node devices 2115~2120 of the fourth column are sequentially connected in series.

[0045] The root device 20 can have only one output port, and the output port thereof is electrically connected to the input port of the node device 2101. In addition, the root device 20 can also have multiple output ports, and the multiple output ports thereof are respectively electrically connected to the multiple input ports of the multiple node devices 2101, 2106, 2111 and 2116.

[0046] Furthermore, the multiple node devices 2101, 2106, 2111 and 2116 of the first row are sequentially connected in series, that is, the output port of the node device 2101 is electrically connected to the input port of the node device 2106, the output port of the node device 2106 is electrically connected to the input port of the node device 2111, and the others are sequentially connected in series.

In some applications, for example, a light pole can be conical, and thus, the number of rows from top to bottom is one light pole, three light poles, five light poles, and seven light poles, in order. The node devices of the present application can also be used to construct the circuit system 2', in which the first column has one node device 2116, the second column has three node devices 2113-2115, the third column has five node devices 2108-2112, and the fourth column has seven node devices 2101-2107.

[0050] The three node devices 2113-2115 in the second column are sequentially connected in series, that is, the output port of the node device 2113 is electrically connected to the input port of the node device 2114, the output port of the node device 2114 is electrically connected to the input port of the node device 2115, and so on. The five node devices 2108-2112 in the third column are sequentially connected in series, and the seven node devices 2101-2107 in the fourth column are sequentially connected in series.

Alternatively, the root device 20 can have multiple output ports, and the multiple output ports are respectively electrically connected to the multiple input ports of the multiple node devices 2101-2107.

[0052] The output port of the node device 2101 in the fourth column and the first row is electrically connected to the input port of the node device 2108 in the third column and the second row, the output port of the node device 2108 in the third column and the second row is electrically connected to the input port of the node device 2113 in the second column and the third row, and the output port of the node device 2113 in the second column and the third row is electrically connected to the input port of the node device 2116 in the first column and the fourth row. In addition, the node devices 2102 and 2108 in the second row are sequentially connected, the node devices 2103, 2109 and 2113 in the third row are sequentially connected, the node devices 2104, 2110, 2114 and 2116 in the fourth row are sequentially connected, the node devices 2105, 2111 and 2115 in the fifth row are sequentially connected, and the node devices 2102 and 2108 in the sixth row are sequentially connected. Through the above architecture, in addition to reducing the maximum number of hops when transmitting control signals, at least part of the node devices 2101-2116 can have multiple transmission paths, thereby avoiding the situation that when at least one transmission path fails, the control signal cannot be successfully transmitted to the node device as the destination device.

[0053] Please refer to Figure 5 , Figure 5 is a schematic block diagram of the node device in the embodiment of the present application. The node devices 2101-2120 described above can be Figure 5 the node device 4, which comprises two input ports 401 and 402, an input selection unit 403, a control unit 404, an execution module 405, an output selection unit 406 and two output ports 407 and 408.

[0054] The input ports 401 and 402 are used to receive control signals on one of the transmission paths. The input selection unit 403 is used to select at least one control signal of the input ports 401 and 402 to the control unit 404. The control unit 404 instructs the execution module 405 to perform corresponding functions (only when the device identification or address corresponding to the control signal is the node device 4, the control signal is executed) according to the control signal, for example, the node device 4 is a digital god card, and the execution module 405 is a display screen for displaying sacrifice information, and the present application is not limited thereto. When the control unit 404 judges that the device identification or address corresponding to the control signal is not the node device 4, the control unit 404 will transmit the control signal to the output selection unit 406. The output selection unit 406 is used to select at least one of the two output ports 407 and 408 to transmit the control signal.

[0055] Please refer toFigure 6 With Figure 7 , Figure 6 is a schematic block diagram of the circuit system of another embodiment of the present application, and Figure 7 is a schematic block diagram of the circuit system of yet another embodiment of the present application. In Figure 6 With Figure 7 , unlike the embodiment of Figure 3 With Figure 4 , the electrical connections between the plurality of node devices 3101-3120 and other components in the circuit system 3, 3' are not like the electrical connections between the plurality of node devices 2101-2120 and other components in the circuit system 2, 2' of Figure 3 , Figure 4 , the electrical connections between the plurality of node devices 2101-2120 and other components are unidirectional connections, but are changed to bidirectional connections, so the plurality of ports of the plurality of node devices 3101-3120 are bidirectional port designs of input / output ports (the plurality of ports of the root device 30 are also bidirectional port designs of input / output ports). In this way, for the plurality of node devices 3101-3120, there can be more transmission paths, and when a specific transmission path fails, the probability that the node device as the destination device cannot receive the control signal is reduced.

The four input / output ports 801-804 are electrically connected to the input / output selection unit 805, and the control unit 806 is electrically connected to the input / output selection unit 805 and the execution module 807.

[0057] The input / output ports 801-804 are used to transmit control signals or to receive control signals. The input / output selection unit 805 is used to select at least one of the input / output ports 801-804 to receive control signals, or to select at least one of the input / output ports 801-804 to transmit control signals. The control unit 806 instructs the execution module 807 to perform corresponding functions according to the control signals (when the device identification or address corresponding to the control signal is the node device 8, the control signal is executed). The control unit 806 will determine that the device identification or address corresponding to the control signal is not the node device 8, at which time the control unit 806 will transmit the control signal to the output input / output selection unit 805, and the input / output selection unit 805 will select at least one of the input / output ports 801-804 to transmit the control signal.
