Based on this, this application sends identification signal to the user's ammeter through the branch module. Specifically, the branch module is used for receiving the identification signal and then determining the user electric meter corresponding to the identification signal to be sent based on the identification signal, so that the transmission line is shortened. For example, a building a has 10 user electric meters, a building B has 10 user electric meters, a building C has 10 user electric meters, the front ends of the building a, the building B and the building C are branch modules, and if an identification signal is sent to the 6 th electric meter of the building B, the identification signal is first sent to the branch modules, and the branch modules identify the identification signal as a signal of the building B, and then the signal is sent to the building B and then sent to the 6 th electric meter. The branching module may be in multiple levels, and the specific number of the branching modules is determined according to actual needs, and the present application is not particularly limited herein.
As a preferred embodiment, the sending of the identification signal to the consumer meter comprises:
and sending an identification signal to a user electric meter by taking the three-phase sine wave transmitted by the power distribution network as a carrier.
In the embodiment, the intelligent terminal takes the three-phase sine wave of power transmission and transmission of the power distribution network as a carrier when sending the identification signal to the user electric meter, the identification signal can be transmitted through the power distribution line of the power transmission and transmission of the power distribution network, a communication line does not need to be additionally arranged, and the cost of the identification signal transmission is reduced.
As a preferred embodiment, the method for sending an identification signal to a user electric meter by using a three-phase sine wave transmitted by a power distribution network as a carrier comprises the following steps:
modulating the identification signal at a preset position of the three-phase sine wave;
generating a distortion signal at a preset position so that the user electric meter demodulates the identification signal of the preset position when receiving the distortion signal;
the three-phase sine wave including the distorted signal is transmitted to a consumer electric meter.
In this embodiment, when the three-phase sine wave transmitted by the power distribution network is used as a carrier to send an identification signal to the user electric meter, the identification signal is modulated to a preset position of the three-phase sine wave, then a distortion signal is set at the preset position, so that the user electric meter can demodulate the identification signal at the preset position when receiving the distortion signal, and finally the three-phase sine wave including the distortion signal is sent to the user electric meter.
Specifically, the three-phase sine wave in the present application is a three-phase sine wave with a frequency of 50Hz and a period of 20ms, and the preset position here may be, but is not limited to, near the positive zero crossing point of the three-phase sine wave.
As a preferred embodiment, the identification signal includes a time stamp and phase information;
the phase information determined by the user electricity meter based on the identification signal comprises:
receiving a three-phase sine wave comprising a distorted signal;
detecting and recording the time of a positive zero crossing point of a three-phase sine wave comprising a distortion signal;
demodulating the identification signal from a three-phase sine wave including the distortion signal when the distortion signal is detected and recording the time when the distortion signal is detected;
calculating a first time difference between the time when the distortion signal is detected and the time when a three-phase sine wave comprising the distortion signal passes through a zero forward direction;
judging whether the first time difference is the same as the time stamp of the identification signal; the timestamp is a second time difference between the time corresponding to the preset position and the time of the positive zero crossing point of the three-phase sine wave;
and if so, determining that the phase information of the user electric meter is the same as the phase information in the identification signal.
In this embodiment, the identification signal includes a time stamp and phase information, where the time stamp is a second time difference between a time corresponding to the set position and a time corresponding to a positive zero crossing of the phase, and the phase information is an a-phase, a B-phase, or a C-phase. At this moment, when determining the phase information, the user electric meter receives the three-phase sine wave including the distortion signal, demodulates the identification signal of the preset position from the three-phase sine wave including the distortion signal when detecting the distortion signal, records the time of the distortion signal, calculates a first time difference between the time of the distortion signal and the time of a forward zero crossing point, compares whether the first time difference is the same as the timestamp of the identification signal, if so, determines whether the phase information corresponding to the user electric meter is the same as the phase information of the received identification signal, and if not, determines that the phase information corresponding to the user electric meter is different from the phase information corresponding to the received identification signal.
In addition, when the frequency of the three-phase sine wave is 50Hz and the period is 20ms, if the difference between the first time difference and the time stamp of the identification signal is 6.67ms, the user electric meter is the next phase of the phase information corresponding to the identification signal; and if the phase information corresponding to the identification signal is the phase A, the phase information of the user electric meter with the difference between the first time difference and the timestamp of the identification signal being 6.67ms is the phase B. If the difference between the first time difference and the timestamp of the identification signal is 12.33ms, the user electric meter is the next phase of the phase information corresponding to the identification signal, and if the phase information corresponding to the identification signal is the A phase, the phase information of the user electric meter, of which the difference between the first time difference and the timestamp of the identification signal is 12.33ms, is the C phase.
As a preferred embodiment, the identification signal further comprises an identification code;
before determining whether the first time difference is the same as the time stamp of the identification signal, the method further includes:
judging whether the identification code of the user electric meter is the same as the identification code of the identification signal or not;
if yes, the step of judging whether the first time difference is the same as the time stamp of the identification code is carried out.
Specifically, each transformer corresponds to some fixed user electric meters, the power supply range or area of each transformer is a distribution area of the transformer, in practical application, in order to save cost, multiple transformers may share a zero line, and thus, when transmitting an identification signal, an area crosstalk problem may occur, that is, a user electric meter not belonging to the transformer may also receive the identification signal and may determine its own phase information according to the identification signal, thereby affecting the success rate of user-related system identification.
Based on this, the identification signal in this application still includes the identification code, and this identification code represents the district that the user's ammeter is located, before judging whether first time difference and identification signal's timestamp are the same, judges whether the identification code of user's ammeter is the same with identification signal's identification code first, if, shows that the user's ammeter that receives identification signal belongs to this district, then judges whether first time difference is the same with identification code's timestamp again.
In summary, the application determines whether the user electric meter belongs to the distribution area by judging the identification code of the user electric meter and the identification code of the identification signal, so as to avoid the crosstalk of the distribution area and improve the success rate of identifying the family relation.
As a preferred embodiment, before sending the identification signal to the user electric meter, the method further includes:
judging whether the clock of the user ammeter is synchronous with the clock of the user ammeter;
if yes, entering a step of sending an identification signal to a user ammeter;
if not, adjusting the clock of the user electric meter to keep the clock synchronous with the clock of the user electric meter, and then entering a step of sending an identification signal to the user electric meter.
It is considered that there may be a case where the own clock is not synchronized with the clock of the user meter due to some circumstances, which affects the inaccuracy of the phase information determined by the user meter based on the identification signal.
Based on the method, before the identification signal is sent to the user electric meter, whether the clock of the user electric meter is synchronous with the clock of the user electric meter is judged, and if the clock of the user electric meter is synchronous, the identification signal is sent to the user electric meter; if the clock is not synchronous, the clock of the user electric meter is adjusted to be synchronous with the clock of the user electric meter, and then the identification signal is sent to the user electric meter, so that the accuracy of the user electric meter for determining the phase information based on the identification signal is improved.
