For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the process flow diagram of present invention station district recognition methods embodiment one, and the executive agent of the present embodiment is the central coordinator (Central Coordinator is called for short CCO) be arranged in concentrator, and as shown in Figure 1, the method for the present embodiment can comprise:
Step 101, described CCO control line of electric force and zero line conducting or not conducting according to platform district recognition sequence and produce the alternating current after processing, alternating current after described process is used for website (Station, be called for short STA) obtain described district's recognition sequence by alternating current after the described process of detection, described district's recognition sequence comprises platform area code.
Concrete, platform district recognition sequence can be binary data sequence, it comprises platform area code, namely this area code also can be binary data sequence, the concrete form of platform district recognition sequence can be synchronization bit, platform area code and effect position, namely CCO can arrange synchronization bit and effect position with STA, make STA when receiving succession of binary number, can according to synchronization bit and effect position, obtain district's recognition sequence, and platform area code wherein, certainly can understand, platform district recognition sequence can be other arbitrary forms, as long as CCO and STA appoints, at CCO by after alternating current sending station district recognition sequence, STA can be good according to a preconcerted arrangement form obtain platform district recognition sequence and platform area code, the concrete form of platform district recognition sequence not with above-mentioned citing as restriction.After above-mentioned explanation is done to the concrete form of platform district recognition sequence, also need to be further explained explanation to platform area code, platform area code in platform district recognition sequence can the platform area code of Shi Yigetai district actual allocated, also can be that the platform area code of actual allocated is carried out the binary number after a mapping as platform area code, as long as CCO and STA appoints, make STA can carry out reflecting the platform area code of penetrating and obtaining actual allocated after receiving this area code.
Alternating current after step 102, described process is by power line transmission extremely each STA.
Concrete, CCO needs that platform is distinguished recognition sequence and is sent to the STA be connected between line of electric force and zero line, unlike the prior art, CCO controls line of electric force and zero line conducting or not conducting according to platform district recognition sequence, to make the waveform generation deformation of alternating current, STA detects the alternating current after process, and then obtains platform district recognition sequence, and the mode of this band to band transfer module district recognition sequence has good anti-interference.Wherein, this line of electric force can be any one in A phase line of electric force, B phase line of electric force and C phase line of electric force, when this line of electric force be A to line of electric force time, CCO control A phase line of electric force and zero line conducting or not conducting make the waveform generation deformation of alternating current, namely the alternating current after process is produced, STA between A phase line of electric force and zero line just can receive the alternating current after this process by line of electric force, and then the alternating current after this process is detected, obtain the platform area code in platform district recognition sequence, thus make STA can know platform district belonging to it.
Further, the specific implementation of step 101 can be:
Described CCO controls line of electric force and zero line conducting or not conducting according to the first zero crossing place of platform district recognition sequence in multiple consecutive periods of alternating current, to produce the alternating current after process on described line of electric force, the one-period of the alternating current after described process is corresponding with a bit of described district's recognition sequence, and described district's recognition sequence comprises platform area code;
Wherein, if a bit of described district's recognition sequence is 1, the first zero crossing place of described CCO in the one-period of alternating current controls described line of electric force and zero line conducting, described alternating current is produced instantaneously to be drawn partially, control described line of electric force and the not conducting of described zero line at the second zero crossing place, described alternating current is not produced and instantaneously draws partially; Or
If a bit of described district's recognition sequence is 0, the first zero crossing place of described CCO in the one-period of alternating current controls described line of electric force and zero line not conducting, described alternating current is not produced instantaneously to be drawn partially, control described line of electric force and the not conducting of described zero line at the second zero crossing place, make described alternating current not produce instantaneous drawing partially.
It should be noted that, above-mentioned " the first zero crossing place " and " the second zero crossing place " its specifically at the actual zero crossings CCO of alternating current by line of electric force and zero line conducting or not conducting, namely locate its not actual zero point.
Concrete, Fig. 2 A is former 220V alternating current voltage waveform schematic diagram, Fig. 2 B is the alternating current voltage waveform schematic diagram after process, Fig. 2 A and Fig. 2 B is the waveform schematic diagram of one-period, wherein the first zero crossing is a point in Fig. 2 A, c point in Fig. 2 B, second zero crossing is the b point in Fig. 2 A, d point in Fig. 2 B, wherein, CCO controls line of electric force and zero line conducting at the first zero crossing place, making alternating current produce one at the first zero crossing place instantaneously draws partially, it is instantaneous draws partially as shown in Figure 2 B, it should be noted that, here CCO at the first zero crossing place by line of electric force and zero line conducting, its specifically actual zero point be about to arrive before by line of electric force and zero line conducting.When binary number is 1, CCO controls line of electric force and zero line and produces at the first zero crossing place in the one-period of alternating current and draw inclined, the second zero crossing place not draw partially; When binary number is 0, CCO control line of electric force and the first zero crossing place of zero line in the one-period of alternating current do not produce draw partially, the second zero crossing place do not draw partially, so just can draw partially and not draw inclined to transmitting digital signals by controlling alternating current generation.
Further, described district's recognition sequence also comprises synchronous head and effect position, and described synchronous head and effect position are used for described STA and identify described district's recognition sequence, and therefrom parse described area code.
The present embodiment, CCO controls line of electric force and zero line conducting or not conducting according to platform district recognition sequence, make the waveform generation deformation of alternating current, namely the alternating current after process is produced, STA detects the alternating current after this process, obtain the platform area code in platform district recognition sequence, just platform district belonging to it can be known, the platform district recognition sequence of this enforcement can effectively be transmitted to whole district by the alternating current after process, effectively can solve tradition high pressure altogether, zero line altogether, carrier wave cross-interference issue altogether and under common cable duct, and this district's recognition sequence can not crosstalk between platform district three-phase, thus STA can be made to obtain platform district information belonging to it.
