[0024] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit this specification. Brief Description of the Drawings

[0025] The accompanying drawings herein are incorporated into the specification and constitute a part of this specification, showing embodiments consistent with this specification, and are used together with the specification to explain the principles of this specification.

[0027] Figure 2 It is a schematic structural diagram of a switch module of a controlled network device involved in this application;

[0028] Figure 3 It is a schematic structural diagram of a network system involved in this application;

[0029] Figure 4 It is a schematic structural diagram of a network system involved in an implementation manner of this application. Specific implementation manner

[0030] Here, the exemplary implementation manners will be described in detail, and the examples are shown in the drawings. When the following description involves the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary implementation manners do not represent all implementation manners consistent with this specification.

[0031] This application provides a controlled network device 100, as Figure 1 shown, including:

[0032] Power supply module 1;

[0033] Optical module 2, connected to the power supply module 1 and receiving power supply from the power supply module 1;

[0034] Switch module 3, connected to the power supply module 1 and the optical receiving detection pin 20 of the optical module 2;

[0035] Service module 4, connected to the switch module 3.

[0036] Among them, if the optical module 2 detects the optical signal on the optical fiber 5, the switch module 3 is turned on to enable the power supply module 1 to supply power to the service module 4; if the optical module 2 does not detect the optical signal on the optical fiber 5, the switch module 3 is turned off to cut off the power supply from the power supply module 1 to the service module 4.

[0037] A power supply pin 21 can be set on the optical module 2, and the power supply module 1 is used to maintain the power-on state of the optical module 2. Even when the service module 4 is not powered on and the controlled network device 100 is in an inoperative state, signals can be generated through the optical module 2 to realize the control of the switch module 3.

[0038] When there is an optical signal in the optical fiber 5 connected to the optical module 2, the optical module 2 can output a first signal. When there is no optical signal in the optical fiber 5 connected to the optical module 2, the optical module 2 can output a second signal. In the case of the first signal, the switch module 3 can be turned on. At this time, the power supply module 1 can supply power to the service module 4 through the switch module 3, enabling the service module 4 to power on and start working. In the case of the second signal, the switch module 3 can be turned off. At this time, the connection between the power supply module 1 and the service module 4 is cut off by the switch module 3, so that the service module 4 stops working.

[0039] It should be noted that according to the pins on the optical module 2, the optical reception detection pin 20 can be an interrupt pin (IntL), a transmission fault pin (Tx_fault), and a receive loss pin (RX_Los). Among them, the interrupt pin is at a high level when the optical module 2 is working normally, and when no optical signal is detected on the optical fiber connected to the optical module 2, the output of the interrupt pin becomes low level. Correspondingly, in the switch module 3, it can be set to turn off when a low level is detected and turn on when a high level is detected.

[0040] Secondly, the optical reception detection pin 20 can be a transmission fault pin. When the optical module 2 is working normally, the transmission fault pin outputs a low level. When no optical signal is detected on the optical fiber connected to the optical module 2, the output of the transmission fault pin becomes high level. Correspondingly, in the switch module 3, it can be set to turn off when a high level is detected and turn on when a low level is detected.

[0041] In addition, the optical reception detection pin 20 can also be a receive loss pin. When the optical module 2 is working normally, the receive loss pin outputs a low level. When no optical signal is detected on the optical fiber connected to the optical module 2, the output of the receive loss pin becomes high level. Correspondingly, in the switch module 3, it can be set to turn off when a high level is detected and turn on when a low level is detected.

[0042] Of course, through the remote control of the optical module 2, it can also be achieved through other pins on the optical module 2. The above is only an example description and does not constitute a limitation to this solution. In addition, there can also be pins for data transmission on the optical module 2, which are not shown in the figure.

[0043] Among them, the switch module 3 can be a switch circuit composed of triodes or can be implemented by a control chip, and there is no limitation on this.

[0044] Optionally, the switch module 3, as Figure 2 shown, includes:

[0045] A switching transistor 30, the control terminal 30A of the switching transistor 30 is connected to the optical receiving detection pin 20 of the optical module 2, the input terminal 30B of the switching transistor 30 is connected to the power supply module 1, and the output terminal 30C of the switching transistor 30 is connected to the service module 4.

[0046] Specifically, the switching transistor 30 can be a triode, such as a transistor and a field effect transistor, etc., and there is no limitation on this. As Figure 2 shown, the switching transistor 30 is a PNP type triode. When the optical module 2 detects an optical signal on the optical fiber, the optical receiving detection pin 20 is pulled to a low level, and there is a voltage difference between the input terminal 30B and the control terminal 30A, so that the input terminal 30B and the output terminal 30C are turned on, enabling the power supply module to supply power to the service module 4. Among them, the resistance between the output terminal 30C and GND can be understood as the equivalent load 40 of the service module 4, and a resistor 31 is provided between the optical receiving detection pin 20 and the control terminal 30A.

[0047] Of course, if the switching module 3 adopts different switching circuit forms, the peripheral circuit settings are also different, and will not be described in detail here.

[0048] Correspondingly, the present application provides a network system, as Figure 3 shown, including any one of the above-mentioned controlled network devices 100 and the main control network device 200. The main control network device 200 can be a routing and switching device, such as a router, a switch, etc. The controlled switching device 100 can be a wireless access point, a wireless controller, etc. connected to the main control network device 200 through an optical fiber 5.

[0049] The main control network device 200 includes a processor 201, a logic device 202, and a main control optical module 203.

[0050] Among them, the logic device 202 is respectively connected to the processor 201 and the main control optical module 203, and the main control optical module 203 is connected to the optical module 2 of the controlled network device 100 through an optical fiber 5.

[0051] The processor 201 of the main control network device 200 sends a light-off signal to the main control optical module 203 through the logic device 202.

[0052] The logic device 202 can be a CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gate Array), etc. The processor 201 writes control instructions into the register of the logic device 202, causing the logic device 202 to output a control signal (such as a light-off signal) to the pins of the main control optical module 203, so as to turn on or off the laser of the main control optical module 203. In this way, when the laser is turned on, an optical signal is transmitted on the optical fiber 5, and when the laser is turned off, the optical signal on the optical fiber 5 disappears.

[0053] If the optical module 2 of the controlled network device 100 does not detect the optical signal sent by the main control optical module 203, the switch module 3 of the controlled network device 100 is turned off to cut off the power supply of the service module 4 of the controlled network device 100 by the power supply module 1 of the controlled network device 100.

[0054] If the optical module 2 of the controlled network device 100 detects the optical signal sent by the main control optical module 203, the switch module 3 of the controlled network device 100 is turned on, so that the power supply module 4 of the controlled network device 100 supplies power to the service module 4 of the controlled network device 100.

[0055] It should be noted that the main control network device 200 can include multiple main control optical modules 203, and each main control optical module 203 can be connected to a controlled network device 100 to control it.

[0056] Optionally, the switch module 3, such as Figure 2 shown, includes:

[0057] A switching transistor 30, the control terminal 30A of the switching transistor 30 is connected to the optical receiving and detecting pin 20 of the optical module 2, the input terminal 30B of the switching transistor 30 is connected to the power supply module 1, and the output terminal 30C of the switching transistor 30 is connected to the service module 4.

[0058] Optionally, the main control network device 200 is a routing and switching device, such as a switch, a router, etc.

[0059] Optionally, the controlled network device 100 is a routing and switching device, a wireless controller, a wireless access point, etc.

[0060] Next, a specific implementation manner is used to describe the controlled network device and the network system involved in the present application. Among them, the network system is as Figure 4 shown. Taking a main control network device as a switch 300 to control a controlled network device as a wireless access point 400 as an example for description.

[0061] The switch 300 includes a processor 310, a CPLD 320, and an optical module 330. The CPLD 320 is respectively connected to the processor 310 and the optical module 330. Specifically, an output pin of the CPLD 320 can be connected to the TX_Disable pin 331 of the optical module 330.

[0062] The wireless access point 400 includes a power module 410, an optical module 420, a switch module 430, and a service module 440. The switch module 430 is respectively connected to the power module 410, the optical module 420, and the service module 440. The switch module 430 includes a triode 431, whose base 431A is connected to the RX_LOS pin 422 of the optical module 420 through a resistor 432, the emitter 431B is connected to the power module 410, the emitter 431C is connected to the service module 440, and the power pin 421 of the optical module 420 is connected to the power module 410.

[0063] Between the optical module 330 and the optical module 420, communication is carried out through the optical fiber 500.

[0064] After the wireless access point 400 is connected to the switch 300 through the optical fiber 500 and powered by the power module 410, the power module 410 supplies power to the optical module 420 through the power pin 421, and the optical module 420 can be powered on to work.

[0065] After the switch 300 and the wireless access point 400 are connected, the optical module 330 has not been started and the laser has not emitted an optical signal. At this time, the staff can send a control instruction to the CPLD 320 through the processor 310 to turn on the optical module 330. After the CPLD 320 receives the light guiding instruction, it rewrites the corresponding register, thereby outputting a low level (i.e., a light guiding signal) to the Tx_Disable pin 331 of the optical module 330. After the Tx_Disable pin 331 of the optical module 330 receives the low level, the optical module 330 turns on the laser and emits an optical signal to the optical module 420 through the optical fiber 500.

[0066] After the optical module 420 receives the optical signal transmitted on the optical fiber 500, the RX_Los pin 422 is pulled to a low level, the voltage difference between the collector 431B and the base 431A is greater than the conduction voltage, the path between the collector 431B and the emitter 431C is conducted, the power module 410 supplies power to the service module 440, and the wireless access point 400 starts to work.

[0067] When the staff determines that it is necessary to turn off the wireless access point 400 to reduce power consumption, the processor 310 issues a light-off instruction to the CPLD 320. The CPLD 320 rewrites the register and outputs a high level (i.e., the light-off signal) to the Tx_Disable pin 331 of the optical module 330. After receiving the light-off signal, the optical module 330 cuts off the laser, and the optical signal transmitted on the optical fiber 500 disappears.

[0068] At this time, the optical module 420 detects that the optical signal on the optical fiber 500 has disappeared, the Rx_Los pin 422 is pulled up to a high level, the voltage difference between the collector 431B and the base 431A is less than the conduction voltage, the path between the collector 431B and the emitter 431C is turned off, the power supply of the power supply module 410 to the service module 440 is cut off, and the wireless access point 400 is turned off.

[0069] In this way, the switch 300 can control the opening and closing of the wireless access point 400 through the optical signal interaction between the optical module 300 and the optical module 420, thereby improving the efficiency of remote control of the controlled network device.

[0070] The technical solutions provided by the embodiments of this specification may include the following beneficial effects:

[0071] In the embodiments of this specification, the power supply module is connected to the optical module of the controlled network device to keep the optical module powered on, detect the optical fiber connected to the optical module, and when an optical signal is detected, turn on the switch module to enable the power supply module to supply power to the service module that processes data of the controlled network device, and start the controlled network device. When no optical signal is detected, turn off the switch module, switch the power supply of the power supply module to the service module, and turn off the controlled network device, so as to realize the remote control of the opening and closing of the controlled network device and improve the efficiency of remote control of the controlled network device.

[0072] It should be understood that this specification is not limited to the exact structure already described and shown in the drawings, and various modifications and changes can be made without departing from its scope.

[0073] The above are only the preferred embodiments of this specification and are not intended to limit this specification. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this specification shall be included within the scope of protection of this specification.
