Further, the second detector 905 is configured to detect a power value of the reflected optical signal, so as to check the status of the ONU according to the power value.
In one embodiment of the application, the states of the ONU comprise an accessed ONU state and a non-accessed ONU state, and the accessed ONU state comprises an ONU on-line state and an ONU non-powered state.
In one embodiment of the present application, when the terminal is used to execute the inventory command, the OLT interface 907 of the optical interface unit may be connected to the OLT device, or may not be connected to the OLT device, and the specific OLT state may be determined according to the OLT optical signal power value detected by the first detector 908. The OLT state includes an accessed OLT state and a non-accessed OLT state.
Specifically, when the terminal executes the inventory command, the OLT apparatus connected to the OLT interface 907 sends an OLT optical signal to the optical interface unit. The OLT optical signal is detected by a first detector 908 of the optical interface unit via a first coupler 903 and its power value is detected. Based on the power value, it is determined that the OLT interface 907 accesses the OLT apparatus, i.e. the state of the OLT is determined.
Similarly, if the OLT interface 907 is not connected to the OLT apparatus, the first detector 908 cannot detect the OLT optical signal, so as to determine that the OLT status is the status of not connected to the OLT apparatus.
It should be noted that, in the handheld maintenance terminal provided in the embodiment of the present application, when the checking instruction is executed, the OLT end interface 907 of the optical interface unit is connected to the OLT device, and the ONU end interface 904 is connected to the ONU device.
Further, the OLT apparatus sends a data packet of the PON network resource protocol, where the data packet arrives at the ONU apparatus connected to the ONU end interface 904 through the first coupler 903.
Further, the ONU device sends an ONU optical signal corresponding to the ONU registration information to the clear-checking functional version based on the data packet. The ONU optical signal is sent to the OLT port interface 907 and the second coupler 902 through the first coupler 903, and is sent to the optical signal processing unit through the second coupler 902.
Further, the optical signal processing unit sends the ONU optical signal to the FPGA module 909 and the MCU module 906 of the data processing unit. Wherein FPGA module 909 is connected to MCU module 906.
Further, the data processing unit amplifies and analyzes the ONU signals to obtain ONU registration information. Based on the authorization of the operator, the authentication information corresponding to the ONU equipment is downloaded through the apk, and whether the registration information and the authentication information of the ONU are consistent is further determined.
It should be further noted that, in the embodiment of the present application, the checking instruction and the checking instruction are issued by the controller on the motherboard.
The handheld maintenance terminal provided by the embodiment of the application realizes the integration of various common functions through the main board, the auxiliary board and the plurality of functional boards, so that the number of carrying equipment is reduced when operation and maintenance personnel work, and the burden of the operation and maintenance personnel is reduced. Meanwhile, the terminal can realize the combined use of various functions by supporting various functions, so that the terminal is applicable to various complex communication environments, and the assembly and maintenance efficiency is improved.
Besides, the clearing and checking function of PON network resources is realized through the clearing and checking function board. The power value of the reflected optical signal is detected through the coupler, the state of the ONU is determined based on the power value, and then whether the ONU exists, is in use or not and other information is determined. Meanwhile, the registration information of the ONU can be checked, compared and judged with the authentication information in the previous registration, whether the registration information and the authentication information are matched is determined, and whether the ONU is the ONU of the unit user, whether the ONU is another unit, or whether the ONU of the unit building user is the ONU of the unit building user or the like is further determined.
By determining the state of the ONU and determining whether the registration information and the authentication information of the ONU are consistent, the problem of disordered wiring of the previously left PON network resources can be quickly combed, and further, the cleaning of idle PON network resources by operation and maintenance personnel and the line correction process of ONU resources with unmatched information are facilitated. The technical problem that operation and maintenance personnel are difficult to rectify and comb the PON network resource wiring confusion in the prior art is solved.
