Problems solved by technology

This solution also realizes the remote control of the switch from the hardware, but the module complexity is high, and the problem to be solved is very simple. It only realizes the control of the switch power switch, and it is a one-way control, and the remote switch cannot transmit data information. To the control terminal, the control terminal can only send data information to the remote switch, and cannot realize other functions, such as device restart, MAC address transfer, device network cable being pulled out and other emergencies.
[0004] The existing technology realizes the remote control of the switch from the hardware with high complexity and solves a single problem. It only realizes the control of the power switch of the switch, and it is a one-way control. The remote switch cannot transmit data information to the control end, the control end can only send data information to the remote switch, and cannot realize other functions, such as feedback and handling of unexpected situations such as device restart, MAC address transfer, and device network cable being pulled out

Embodiment 1

[0032] An input and output interface includes a connected input interface and an output interface. Among them, the input interface includes:

[0033] Isolated power supply module, used to convert 12V power supply to 3.3V power supply;

[0034] The interface module is respectively connected to the isolated power supply module and the output interface of another input-output interface, and is used for signal transmission between the output interface.

[0035] Among them, such as figure 1 As shown, the isolated power supply module includes: a pull-up resistor R1, a voltage conversion chip U1, a first filter unit, and a second filter unit. One end of the pull-up resistor R1 is connected to +12V voltage, and the other end is connected to the CTRL end of the chip U1 and the grounded capacitor C4. The first filter unit includes an inductor L1 and capacitors C1, C2, and C3 connected in parallel. One end of the capacitor C1 and the pull-up resistor R1 are both connected to a voltage...

Embodiment 2

[0043] According to the input and output interface provided in the first embodiment above, this embodiment provides a switch remote monitoring device including the input and output interface.

[0044] A switch remote monitoring device comprises a PC, a master switch and a slave switch connected in sequence. Wherein, the master switch and the slave switch both include an input and output interface, and the input interface Ain of the master switch is connected to the output interface Bout of the slave switch, and the output interface Aout of the master switch is connected to the slave switch. The input interface Bin of the switch is connected.

[0045] When the slave switch is idle or fails, the information is fed back to the Ain interface through the interface Bout. After the master switch receives the information, it informs the PC, and the PC transmits the control command to the Bin interface through the Aout interface of the master switch, so that the master switch can commu...

Abstract

The invention provides input and output interfaces and a switcher remote monitoring device. The input and output interfaces comprise an input interface and an output interface, wherein the interface comprises an isolation power module; and an interface module which is connected with the isolation power module and the output interface. The interface module comprises a first terminal (J1) and a photoelectric coupler (U2), which are connected with each other. The first interface of the first terminal (J1) is connected with one end of a light emitter of the photoelectric coupler (U2) through a first inductor (L2). The second interface of the first terminal (J1) is connected with the output end of the isolation power module through a first resistor (R2). One end of a light receiver of the photoelectric coupler (U2) is connected with a chip. Through the interfaces, a function of monitoring a plurality of switchers at the same time through one PC is achieved from the aspect of hardware. The isolation power supply is employed, thereby improving the anti-interference capability, the resistance to lightning stroke, the safety and stability, and achieving the remote monitoring. Moreover, the current broadband of a switcher network port is not occupied.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an input and output interface and a remote monitoring device for a switch. Background technique [0002] A switch (Switch), also called a switching hub, is a network device used for electrical (optical) signal forwarding. It regenerates information and forwards it to a designated port after internal processing. It has automatic addressing capabilities and switching effect. It can provide exclusive electrical signal paths for any two network nodes connected to the switch. However, in a local area network, if you want to remotely view the information of a switch, or remotely operate the information of one or more switches, it is inconvenient for the network administrator. [0003] At present, the patent "A remote control device for switch power supply" (application number: 201410286198) provides a remote control device for switch power supply, including a control module, a si...
