The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present description.
The present application provides a controlled network device 100, as shown in fig. 1, including:
a power module 1;
the optical module 2 is connected with the power module 1 and receives power supply of the power module 1;
the switch module 3 is connected with the power module 1 and a light receiving detection pin 20 of the optical module 2;
and the service module 4 is connected with the switch module 3.
If the optical module 2 detects an optical signal on the optical fiber 5, the switch module 3 is turned on, so that the power module 1 supplies 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 of the power module 1 to the service module 4.
The optical module 2 may be provided with a power pin 21, and the power pin 1 maintains the power of the optical module 2, so that even if the service module 4 is not powered on and the controlled network device 100 is in an inoperative state, a signal can be generated by the optical module 2, thereby controlling the switch module 3.
The optical module 2 may output a first signal when an optical signal is present in the optical fiber 5 to which the optical module 2 is connected, and the optical module 2 may output a second signal when an optical signal is not present in the optical fiber 5 to which the optical module 2 is connected. Under the condition of the first signal, the switch module 3 may be turned on, and at this time, the power module 1 may supply power to the service module 4 through the switch module 3, so that the service module 4 is powered on and started to start working. In the case of the second signal, the switching module 3 can be turned off, at which point the connection of the power module 1 to the service module 4 is cut off by the switching module 3, so that the service module 4 stops operating.
It should be noted that, according to the pins on the optical module 2, the optical reception detection pin 20 may be an interrupt pin (IntL), a transmission failure pin (Tx _ fault), and a reception loss pin (RX _ Los). The interrupt pin is at a high level when the optical module 2 works normally, and when no optical signal is detected on the optical fiber connected to the optical module 2, the output of the interrupt pin changes to a low level, and correspondingly, in the switch module 3, the interrupt pin can be set to be turned off when the low level is detected, and turned on when the high level is detected.
Secondly, the optical reception detection pin 20 may be a transmission failure pin, which outputs a low level when the optical module 2 works normally, and when no optical signal is detected on the optical fiber connected to the optical module 2, the transmission failure pin output becomes a high level, and correspondingly, in the switch module 3, the transmission failure pin may be set to be turned off when the high level is detected and turned on when the low level is detected.
In addition, the optical receiving detection pin 20 may also be a receiving missing pin, which outputs a low level when the optical module 2 works normally, and when no optical signal is detected on the optical fiber connected to the optical module 2, the receiving missing pin output changes to a high level, and correspondingly, in the switch module 3, the receiving missing pin may be set to be turned off when the high level is detected, and to be turned on when the low level is detected.
Of course, the remote control of the optical module 2 may also be implemented by other pins on the optical module 2, which is described above only by way of example and does not limit the present solution. In addition, the optical module 2 may further have pins for implementing data transmission, which are not shown in the figure.
The switch module 3 may be a switch circuit formed by a triode, or may be implemented by a control chip, which is not limited to this.

Specifically, the switch tube 30 may be a triode, such as a transistor and a field effect transistor, without limitation. As shown in fig. 2, the switch tube 30 is a PNP type triode, and when the optical module 2 detects an optical signal on an optical fiber, the light receiving detection pin 20 is pulled to a low level, and a voltage difference exists between the input end 30B and the control end 30A, so that the input end 30B and the output end 30C are conducted, and the power module supplies power to the service module 4, where a resistance between the output end 30C and GND can be understood as an equivalent load 40 of the service module 4, and a resistance 31 is disposed between the light receiving detection pin 20 and the control end 30A.

Correspondingly, the present application provides a network system, as shown in fig. 3, including any one of the controlled network device 100 and the master network device 200. The master network device 200 may be a routing switch device, such as a router, switch, etc. The controlled switching device 100 may be a wireless access point, a wireless controller, etc. connected to the master network device 200 by an optical fiber 5.
The master control network device 200 includes a processor 201, a logic device 202, and a master control optical module 203.
The logic device 202 is respectively connected to the processor 201 and the master control optical module 203, and the master control optical module 203 is connected to the optical module 2 of the controlled network device 100 through the optical fiber 5.
The processor 201 of the master network device 200 sends an optical cutoff signal to the master optical module 203 through the logic device 202.
The Logic Device 202 may be a CPLD (Complex Programmable Logic Device), a Field Programmable Gate Array (Field Programmable Gate Array), or the like, and the processor 201 writes a control instruction into a register of the Logic Device 202, so that the Logic Device 202 outputs a control signal (such as an optical cutoff signal) to a pin of the main control optical module 203 to turn on or off the laser of the main control optical module 203, so that when the laser is turned on, the optical signal is transmitted on the optical fiber 5, and when the laser is turned off, the optical signal disappears on the optical fiber 5.
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 power module 1 of the controlled network device 100 to the service module 4 of the controlled network device 100;
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 module 4 of the controlled network device 100 supplies power to the service module 4 of the controlled network device 100.
It should be noted that the master control network device 200 may include a plurality of master control optical modules 203, and each master control optical module 203 may be connected to one controlled network device 100 to control the same.
Optionally, the switch module 3, as shown in fig. 2, includes:
a control end 30A of the switch tube 30 is connected to the light receiving detection pin 20 of the optical module 2, an input end 30B of the switch tube 30 is connected to the power module 1, and an output end 30C of the switch tube 30 is connected to the service module 4.
Optionally, the master network device 200 is a routing switch device, such as a switch, a router, or the like.
Optionally, the controlled network device 100 is a routing switch device, a wireless controller, a wireless access point, or the like.
The following describes the controlled network device and the network system according to a specific embodiment, where the network system is as shown in fig. 4, and a master network device is taken as the switch 300 to control a controlled network device as the wireless access point 400.
The switch 300, including the processor 310, the CPLD320 and the optical module 330, is connected to the CPLD320 and the optical module 330, respectively. Specifically, one output pin of CPLD320 may be connected to TX _ Disable pin 331 of optical module 330.
The wireless access point 400 includes a power module 410, an optical module 420, a switch module 430, and a service module 440, where the switch module 430 is connected to the power module 410, the optical module 420, and the service module 440, respectively. The switch module 430 includes a transistor 431 having a base 431A coupled to the RX _ LOS pin 422 of the optical module 420 through a resistor 432, an emitter 431B coupled to the power module 410, an emitter 431C coupled to the service module 440, and a power pin 421 of the optical module 420 coupled to the power module 410.
After the wireless access point 400 is connected to the switch 300 through the optical fiber 500 and power is input and supplied through 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 work after being powered on.
After the switch 300 and the wireless access point 400 are connected, the optical module 330 is not activated and the laser does not generate an optical signal. At this time, the operator can issue a control command to the CPLD320 through the processor 310 to turn on the optical module 330, and after the CPLD320 receives the light guide command, the corresponding register is rewritten, so as to output a low level (i.e., a light guide signal) to the Tx _ Disable pin 331 of the optical module 330. After Tx _ Disable pin 331 of optical module 330 receives the low level, optical module 330 turns on the laser and transmits an optical signal to optical module 420 through optical fiber 500.
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, a voltage difference between the collector 431B and the base 431A is greater than a conducting voltage, a 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 operate.
When the operator determines that the wireless access point 400 needs to be closed to reduce power consumption, the processor 310 issues an optical interrupt command to the CPLD320, the CPLD320 rewrites the register, and outputs a high level (i.e., an optical interrupt signal) to the Tx _ Disable pin 331 of the optical module 330. When the optical module 330 receives the light-off signal, the laser is turned off, and the optical signal transmitted through the optical fiber 500 disappears.
At this time, the optical module 420 detects that the optical signal on the optical fiber 500 disappears, the Rx _ Los pin 422 is pulled to a high level, the voltage difference between the collector 431B and the base 431A is smaller than the on-voltage, the path between the collector 431B and the emitter 431C is turned off, the power supply module 410 cuts off the power supply to the service module 440, and the wireless access point 400 is turned off.
Thus, the switch 300 can control the wireless access point 400 to be opened and closed through the optical signal interaction between the optical module 300 and the optical module 420, so as to improve the efficiency of remote control of the controlled network device.
The technical scheme provided by the implementation mode of the specification can have the following beneficial effects:
in an embodiment of this specification, an optical module of a controlled network device is connected through a power module, the optical module is kept in a charged state, an optical fiber connected to the optical module is detected, when an optical signal is detected, a switch module is turned on, so that the power module supplies power to a service module for performing data processing on the controlled network device, the controlled network device is started, when the optical signal is not detected, the switch module is turned off, the power supply of the service module by the power module is switched, so that the controlled network device is turned off, thereby enabling remote control of turning on and off of the controlled network device, and improving the efficiency of remote control of the controlled network device.
It will be understood that the present description is not limited to the precise arrangements described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof.
The above description is only for the purpose of illustrating the preferred embodiments of the present disclosure and should not be taken as limiting the present disclosure, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
