Be how the example explanation utilizes the present embodiment identifier to carry out the identification of platform district with one of them service end 2 below:
Processor II 2-1 control carrier communication unit II 2-3 in a, the service end 2 is to being positioned at the MAC Address that several main control end 1 of not distinguishing on the same stage report self; And an initial trusted value is set in reporting information; Report the process (being that signal transfers to main control end from service end) every warp once to transmit confidence values and add one; Be the relaying degree of depth (current confidence values and initial trusted value poor) and add one, main control end 1 will be carried the relaying depth information of this table number when replying acknowledgement frame.
After carrier communication unit I 1-3 in b, each main control end 1 receives the reporting information of service end 2; It is carried out demodulation and transfers to processor I 1-1; Processor I 1-1 obtains and note current confidence values or main control end, and (the initial trusted value that is provided with of supposing to give the correct time on the service end is 0 with respect to the relaying degree of depth of service end; After 2 forwardings, received by a certain main control end; Then the current confidence values noted of this main control end is 2; Be main control end with respect to the relaying degree of depth of service end be 2, main control end will be carried the relaying depth information of this table number when replying acknowledgement frame), control carrier communication unit I 1-3 simultaneously with this confidence values or the relaying degree of depth; And the platform district information of self (platform district information is sent to main control end through palm machine, so the platform district information of each main control end is set) is modulated to carrier signal and is sent to service end 2 through line of electric force.
After carrier communication unit II 2-3 in c, the service end 2 receives the carrier signal that each main control end 1 sends over; It is carried out demodulation and transfers to processor II 2-1; Processor II 2-1 notes the confidence values or the relaying degree of depth in each carrier signal; And corresponding platform district information, the size of each confidence values or the relaying degree of depth relatively then.For avoiding the mutual interference of unlike signal phase, if receive the signal that a plurality of main control end 1 are sent simultaneously, then these signals are all abandoned reception again in the receiving course.
Processor II 2-1 in d, the service end 2 with minimum confidence values or the corresponding platform district information of the minimum relaying degree of depth, is sent to the user side ammeter box corresponding with this service end through RS485 communication unit II 2-4.Because service end 2 every warp in reporting process is once transmitted confidence values and is just added one; Can know that the current confidence values when main control end 1 receives reporting information is more little; Explain that the number of times of transmitting is few more; The number of times that is relaying fewer (the relaying degree of depth is more little) simultaneously for a certain service end 2, passes through the number of times of transmitting when the signal in other districts transfers to this service end; In the time of generally can transferring to this service end greater than this TV station district signal the hop count of process, so this service end is positioned at same district with minimum confidence values or the corresponding main control end 1 of the minimum relaying degree of depth.Service end 2 is sent to the user side ammeter box 3 corresponding with this service end with minimum confidence values or the corresponding platform district information of the minimum relaying degree of depth in this step, thereby has realized belonging to this service end 2 corresponding electric supply meter casees 3 the automatic identification in platform districts.
After controller 3-1 in e, the ammeter box 3 receives platform district information, this district's information as data under the platform district of oneself, and is sent to the main website of power supply administration through GPRS, inform power supply administration, thereby realize the automatic identification in each table meter 3-2 ownership platform district.
Present embodiment also can be judged service end 2 affiliated platform districts through signal intensity, and its concrete steps are following:
Carrier communication unit II 2-3 in a, the service end 2 receives several and does not distinguish the carrier signal (including platform district information in the signal) that transmits on the same stage; And with transferring to processor II 2-1 after this signal demodulation; Calculate the intensity of each received district's signal by processor II 2-1; And note each signal intensity and corresponding platform district information, compare the size of each signal intensity then.For avoiding the mutual interference of unlike signal phase, if receive the signal that a plurality of districts send simultaneously, then these signals are all abandoned reception again in the receiving course.
Processor II 2-1 in b, the service end 2 is sent to the user side ammeter box corresponding with this service end through the RS485 communication unit II 2-4 platform district information that strongest signal strength is corresponding.Because the carrier signal in other districts will transfer to this TV station district; Through the earth transmission, or pass transformer after which kind of mode no matter power line transmission be still; Attenuation of signal intensity is all bigger; Therefore, under the certain situation of the relaying degree of depth, service end 2 main control end 1 corresponding with strongest signal strength is positioned at same district; Service end 2 is sent to the user side ammeter box 3 corresponding with this service end with the platform district information in 1 signalling of main control end of strongest signal strength correspondence in this step, thereby has realized belonging to this service end 2 corresponding electric supply meter casees 3 the automatic identification in platform districts.
After controller 3-1 in c, the ammeter box 3 receives platform district information, this district's information as data under the platform district of oneself, and is sent to the main website of power supply administration through GPRS, inform power supply administration, thereby realize the automatic identification in each table meter 3-2 ownership platform district.
Present embodiment can also be judged service end 2 affiliated platform districts through the mistiming of zero crossing, and its concrete steps are following:
Carrier communication unit II 2-3 in a, the service end 2 receives several and does not distinguish the carrier signal (including platform district information in the signal) that transmits on the same stage; And the signal that will receive after time point (the time of reception points of signal heads frame data), self zero crossing (obtaining through zero crossing circuitry) and the demodulation of each signal transfers to processor II 2-1; Calculate the time difference of said each time point and self zero crossing by processor II 2-1, and note each time difference and corresponding platform district information; The zero crossing time difference of the big more explanation carrier wave of this difference transmitting element (main control end) and receiving element (service end) is big more.In addition; Because carrier signal is in voltage over zero, to send, and its transmission speed is very fast, the time phase difference that sends and receive is very little; Therefore almost can ignore, aforementioned difference also is appreciated that the mistiming into voltage over zero and service end 2 self zero crossing.
Processor II 2-1 in b, the service end 2 is sent to the user side ammeter box corresponding with this service end through the platform district information in RS485 communication unit II 2-4 1 signalling of main control end that minimal difference is corresponding.Owing to A, B, three phase places of C are arranged in inside, same district, if service end 2 in the A phase place, the received general signal that sends when all being the voltage zero-cross of A phase place, and the phase place zero crossing mistiming differ very little; If the signal that other districts send; Probably send through the earth; This moment, signal possibly be B phase place and C phase place, and the mistiming of its voltage over zero and service end 2 self zero crossing will be bigger, even the signal that other districts send also is the A phase place; Because the load and the transmission medium in platform district change, the time point of detected zero crossing also can have a certain distance with the zero crossing time of oneself; Therefore service end 2 main control end 1 corresponding with above-mentioned minimal difference is positioned at same district.Service end 2 is sent to the user side ammeter box 3 corresponding with this service end with the platform district information in 1 signalling of main control end of minimal difference correspondence in this step, thereby has realized belonging to this service end 2 corresponding electric supply meter casees 3 the automatic identification in platform districts.
After controller 3-1 in c, the ammeter box 3 receives platform district information, this district's information as data under the platform district of oneself, and is sent to the main website of power supply administration through GPRS, inform power supply administration, thereby realize the automatic identification in each table meter 3-2 ownership platform district.
Above-mentioned three kinds of methods can independently be discerned; Also can mutually combine and discern, promptly when adopting the relaying degree of depth can't discern under the service end 2 the platform district, utilize signal intensity to discern; If when adopting signal intensity also can't discern, then adopt the mistiming of zero crossing to discern; The method that can also adopt three kinds of methods to verify is each other discerned, and promptly at first adopts relaying degree of depth identification service end 2 affiliated platform districts, adopts signal intensity identification then; Adopt the mistiming of zero crossing to discern at last; After three kinds of method identifications finished, the contrast recognition result was with the accuracy of guaranteeing to discern.
As shown in Figure 7, in the actual mechanical process, utilize palm machine will include the ZigBee signal of platform district information; Send to the ZigBee communication unit 1-6 of main control end 1, the carrier signal that will include platform district information of the power line carrier communication unit 1-3 through main control end 1 sends on the line of electric force again, and service end 2 is separated the carrier signal on the line of electric force and receive; Utilize the aforementioned identification method simultaneously; To be arranged in the platform district information of 1 signalling of main control end in same district with this service end, transfer to ammeter box 3 through photoelectricity, RF or RS485 communication link, after the controller 3-1 in the ammeter box 3 receives platform district information; With this district's information as data under the platform district of oneself; And send to the main website of power supply administration through GPRS, inform power supply administration, thereby realize the automatic identification in each table meter 3-2 ownership platform district.
