Description

Remote Multi Network Selector

The present invention is a remote multi-network selector, which separates the network into an internal network and an external network. It is a device designed to enable multiple network networks to be used in a single network line of a client by physically connecting and blocking transmission paths at a hub end by a signal of a client computer.

The object of the present invention is to implement the use of multiple network networks in a single network line of a client by configuring a transmission path of a hub at a remote location by a signal of a client computer. An input port 110 for receiving a selection control signal and a network transmission / reception signal for this purpose; A hub connection connector unit 150 for connecting to hubs such as an internal network and an external network; A signal detection and response unit (160) for detecting a signal of an input signal and responsive to a client computer of a power supply state of the apparatus; A relay driving circuit unit 120 for driving the relay according to the detected signal; A switching unit 130 constituting a transmission path in response to the relay driving circuit unit; And a display unit 140 for displaying the state of the transmission path. Generally, UTP cable is used as the transmission line of the network and only 4 lines of 1, 2, 3, and 6 are used to communicate. Therefore, it can be used for the input and output of the control signal by using a separate reserve line. In addition, the control signal maintains only "high" or "low" signals, thereby minimizing network attenuation of the signal lines. According to the configuration of the present invention, it is possible to implement the use of multiple network networks in a single network line of the client.

Hereinafter, a remote multi-network selection apparatus of a computer system according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings. Similar functional blocks in the figures are represented by the same or similar reference numerals as possible.

1 is a diagram illustrating a general multiple network configuration. Referring to Figure 1, it can be seen that the network line of the computer is connected to the client computer in multiple. Network lines that connect to client computers can be laid at varying distances from a few meters up to 100 metres, and they must be duplicated by as many networks. The remote multi-network selector is intended to provide a condition for configuring a transmission path of multiple network networks using a single network line of a client.

Figure 2 shows a block diagram of a remote multiple network selection apparatus 100 of the present invention. The control signal input to the input port 110 is a signal is detected by the signal detection and response unit 160, the relay driving circuit unit 120 operates according to the detected signal to the relay driving circuit unit 120 By this, the switching unit 130 operates. In addition, the display unit 140 displays the operation state of the switching unit. Hub connection connector 150 is configured to connect the connector input of the RJ-45 used in the general LAN network.

Input port 110 is configured to connect the RJ-45, used for network transmission, reception No. 1, No. 2, No. 3, No. 6 and No. 4 of the external network selection signal, internal network selection signal It consists of No. 5 and No. 7 GND and No. 8 which outputs the power status of the remote multi-network selector. The control signals input at 4 and 5 are variously attenuated by the length of the inconsistent network line. Each control signal is converted into a signal of a predetermined level by a signal detection and response unit 160 composed of resistors R49, R17, R33, and R1 and zener diodes ZD17 and ZD1, and is detected. The brightness of LD16) is kept the same. 75 ohms, 50 ohms, 75 ohms, 50 ohms were used for the resistors, and 1 N5226 was used for Zener diodes, respectively. In addition, the protection resistance (R65) was used when sending the power status of the remote multi-network selector to the client computer. In addition, the signal detected at # 4, the external network selection signal, operates the relay driving circuit unit 120. The relay driving circuit unit 120 uses a two-stage TR driving circuit excellent in noise characteristics to prevent malfunction due to noise. The relay driving circuit unit 120 includes resistors R81, R98, and R99, transistors Q1, Q17, and a capacitor C1, and the resistors include 150 kV, 10 kV, and 10 kV. TIP32C and C3198 were used, and 22uF capacitor was used. The LED LD16 of the display unit emits red light in the external network and green light in the internal network. The diode D1 of the relay driving circuit unit 120 removes the counter electromotive current during the relay driving. 1N4148 was used as the diode. In addition, the capacitors BC1, BC17, and BC33 connected to the control signal line of the signal detection and response unit 160 use 0.1 uF to remove noise. The circuit shows one module and can be manufactured for 8 modules or 16 modules using several modules.

Although the present invention has been described with reference to the drawings and limited, for example, various changes and modifications are possible without departing from the technical spirit of the present invention according to the proposal.

As described above, the present invention can selectively configure and use multiple network transmission paths in a single network line of the client by the control signal of the client computer. Therefore, in the existing network environment consisting of a single line, it is possible to use multiple physically separated network without separate line construction.
