Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
First embodiment
As described in the background art, the conventional line fault needs manual analysis, if data cannot be acquired for a plurality of consecutive days, people need to be sent to the site to be checked one by one, and the problem of a terminal or an ammeter cannot be judged. People need to be frequently sent to carry out on-site inspection, a large amount of manpower and material resources are wasted, and the efficiency is low.
In view of this, in order to solve the technical problem, the application provides an ammeter line anomaly detection method, the electric power terminal is used for acquiring instructions and sending the instructions to a plurality of ammeters, then whether an ammeter line or an electric power terminal breaks down is judged according to the condition of data feedback of the plurality of ammeters, and if the electric power terminal breaks down, whether the electric power terminal breaks down or the ammeter line breaks down is judged, so that fault reasons do not need to be checked one by one on a working personnel site, meanwhile, whether the electric power terminal or the representative line breaks down can be quickly positioned, and the problems that the positioning problem is slow and the detection efficiency is low are solved.
The following describes an exemplary method for detecting an abnormal meter line, which is provided by the present application, with a power terminal as an execution subject.
Referring to fig. 1, the method for detecting circuit abnormality in the meter includes:
s101, receiving a detection signal sent by a background, wherein the detection signal at least comprises a data type to be collected.
And S103, generating a collection instruction according to the type of the data to be collected, and issuing the collection instruction to each ammeter.
And S105, receiving data fed back by the electric meter according to the acquisition instruction, and marking the electric meter without the fed back data as a suspected line abnormal electric meter.
And S107-a, when the plurality of electric meters are all non-suspected line abnormal electric meters, judging that the lines and the electric power terminals of the plurality of electric meters are all in a normal state.
And S107-b, when the suspected line abnormal electric meters are arranged in the plurality of electric meters, judging the suspected line abnormal electric meters as the line abnormal electric meters, and generating first fault information to send the first fault information to a background, wherein the first fault information is associated with the address of the line abnormal electric meter.
And S107-c, when all the electric meters are suspected line abnormal electric meters, judging that the electric power terminal is in a fault state, and generating second fault information to send the second fault information to a background, wherein the second fault information is associated with the address of the electric power terminal.
Referring to fig. 2, in the power grid system 300, the power grid system generally includes a background 320, a power terminal 310 and an electric meter 330, where the background 320, the power terminal 310 and the electric meter 330 are sequentially in communication connection, where the electric meter 330 is configured to adopt power consumption of a user and send the power consumption to the power terminal 310, the power terminal 310 is configured to receive the power consumption sent by a plurality of electric meters 330, for example, one power terminal 310 is arranged in a cell, the power terminal 310 is utilized to obtain power consumption of each electric meter 330 in the cell, and the obtained power consumption is uniformly uploaded to the background 320, so that the background 320 obtains the power consumption of each electric meter 330, and the background 320 is configured to process the power consumption, for example, calculate an electric fee or the like that each user needs to pay according to the power consumption.
In the present application, when it is necessary to check whether there is an abnormality in the line of the electric meter 330, the back-end 320 may be controlled to generate a corresponding detection signal in a manual or automatic manner, where the detection signal at least includes a type of data to be collected. For example, the type of data to be collected may be voltage information or the like.
After the background 320 generates the detection signal, the detection signal is sent to the power terminal 310, and the power terminal 310 generates an acquisition instruction after receiving the detection signal, and sends the acquisition instruction to each electric meter 330, so as to acquire data of the electric meter 330 through the acquisition instruction.
After receiving the collection instruction, the electric meter 330 may feed back corresponding data to the power terminal 310 according to the collection instruction, for example, if the type of the data to be collected is voltage information, then after receiving the collection instruction, the electric meter 330 may feed back current voltage information to the power terminal 310. Meanwhile, the power terminal 310 determines whether the data fed back by each electric meter 330 is received, and when the data fed back by the electric meter 330 is not received, it indicates that the line of the electric meter 330 is abnormal, and the power terminal 310 marks the line as a suspected line abnormal electric meter.
As a possible implementation manner of the present application, after the power terminal 310 determines the conditions of the data fed back by all the electric meters 330, the conditions of the suspected line abnormal electric meters are analyzed.
If none of the electric meters 330 is the suspected line abnormal electric meter, that is, the number of the suspected line abnormal electric meters is 0, it can be determined that each electric meter 330 and the line and the power terminal 310 are in a normal state.
If some of the electric meters 330 are suspected line abnormal electric meters, it indicates that some of the electric meters 330 can perform normal communication with the power terminal 310, and some of the electric meters 330 cannot perform normal communication with the power terminal 310. While the first failure information is sent to the back office 320.
Moreover, each electric meter 330 is provided with an address, and in order to realize the maintenance of the comparative electric meter 330 more accurately by a maintenance person, the first fault information is associated with the address of the line abnormal electric meter. For example, 10 electric meters 330 are connected to the electric terminal 310, and when 9 electric meters are normal electric meters and one electric meter is a suspected line abnormal electric meter, the electric terminal 310 may determine that the suspected line abnormal electric meter is a line abnormal electric meter. Meanwhile, the address is information for distinguishing each electric meter 330, for example, the address may be an IP address, and may also be a number of the electric meter 330.
In the actual use process, even if the lines of the electric meters 330 are abnormal, only a small part of the lines of the electric meters 330 are abnormal, and the situation that all the lines of the electric meters 330 are abnormal due to the lines is avoided. Therefore, when all the electric meters 330 are suspected line abnormality electric meters, the electric terminal 310 determines that it is in a fault state and generates second fault information to send the second fault information to the background 320, wherein the second fault information is associated with the address of the electric terminal 310.
Since the power terminal 310 can only instruct IF … ELSE or other instructions during program execution, as an implementation manner of the present application, after the power terminal 310 performs the step of marking the suspected line abnormal meter, it can determine whether the circuit terminal line has a fault through two determination processes. That is, it is first determined whether the number of the suspected line electricity meters 330 is zero, and if not, it is then determined whether the number of the suspected line electricity meters 330 is equal to the number of all the electricity meters 330.
According to the method for detecting the abnormity of the electric meter line, whether the electric line or the power terminal has faults or not can be quickly positioned, so that the detection efficiency is improved, and maintenance personnel can maintain the electric line or the power terminal more quickly.
As an implementation manner of the present application, the detection signal further includes a data acquisition period, please refer to fig. 3, and S103 includes:
s103-1, generating an acquisition instruction according to the type of the data to be acquired, and issuing the acquisition instruction to each ammeter according to the acquisition data period.
In this application, the data collecting period may be two, where one of the data collecting periods is to collect data only once, and the data collecting period is the time for starting the data collecting task, for example, the data collecting period is 15 minutes, and when the time of 15 minutes is up, the power terminal 310 starts the data collecting task, and starts to copy and read the data of the user electricity meter 330 according to the data type item collected by the master station configuration, that is, at this time, the collecting instruction is issued to each electricity meter 330.
If the other is periodic data collection, the data collection period is a clock period, for example, the data collection period is 15 minutes, and the power terminal 310 sends a data collection instruction to the electricity meter 330 every 15 minutes, so that the electricity meter 330 can feed back corresponding data, and further periodically determine whether a line of the electricity meter 330 fails.
Of course, in other embodiments, the detection signal may also include other signals, such as a user profile, i.e. a user's table number, etc., through which the power terminal 310 may selectively collect data of the power meter 330. For example, 10 electric meters 330 are connected to a certain electric terminal 310, and the detection instruction sent by the background 320 includes the meter numbers of three electric meters 330, so that the electric terminal 310 can collect data of the 3 electric meters 330.
Referring to fig. 4, as an implementation manner of the present application, S105 includes:
and S105-1, sequentially taking each electric meter as a target electric meter.
And S105-2, when data fed back by the target electric meter according to any one type of data to be collected is not received, marking the target electric meter as a suspected line abnormal electric meter.
The types of the data to be collected include multiple types, the power terminal 310 may sequentially use each electric meter 330 as a target electric meter, and further determine whether the target electric meter receives all types of the data to be collected, and if so, mark the target electric meter as a suspected line abnormal electric meter.
For example, if the data types to be collected include a first data type and a second data type, the power terminal 310 will sequentially use each electric meter 330 as a target electric meter to determine whether to feedback data of the first data type and the second data type. If no feedback exists, the electric meter is marked as a suspected line abnormal electric meter.
Moreover, as a possible implementation manner, taking the example that the data type to be collected includes a first data type and a second data type, the determining process specifically includes:
firstly, judging whether data fed back by a target ammeter according to a first data type is received, and if the data fed back by the target ammeter according to the first data type is not received, issuing a collection instruction to the target ammeter again. And when the number of times of issuing the acquisition instruction reaches a threshold value and the data fed back by the target ammeter according to the first data type is not received, switching to receiving the data fed back by the target ammeter according to the second data type. Similarly, when the data fed back by the target ammeter according to the second data type is not received, the acquisition instruction is issued to the target ammeter again, and when the frequency of issuing the acquisition instruction reaches a threshold value and the data fed back by the target ammeter according to the second data type is not received, the target ammeter is marked as a suspected line abnormal ammeter.
Certainly, the types of data to be collected may also include more types, and the present application is not limited in any way, for example, the types of data to be collected include forward active electric energy, reverse active electric energy, voltage, and current, when the power terminal 310 acquires the data of the electric meter 330, if a certain piece of data of the data of a certain electric meter 330 is not collected, the power terminal 310 may resend the command to collect the data, and if no feedback data is received after 3 times of continuous sending, the power terminal 310 switches to the next type of data to be collected. If all the data collected from a certain ammeter 330 do not receive the feedback information, it is determined that the ammeter 330 is an abnormal ammeter of a suspected line.
Moreover, when all the data in a suspected line abnormal electric meter are not collected, the address of a non-suspected line abnormal electric meter which does not feed back all the data and the type of the non-fed back data are also associated with the first fault information generated by the power terminal 310. Similarly, even if it is determined that the lines of the electric meters 330 and the power terminal 310 are all in a normal state, if all the data in a suspected line abnormal electric meter are not collected, the power terminal 310 may still feed back corresponding fault information, for example, third fault information, where the third fault information is only associated with the address of a non-suspected line abnormal electric meter that does not feed back all the data and the type of the data that is not fed back.
Through the implementation manner, whether the line of the electric meter 330 or the power terminal 310 breaks down or not can be judged, whether a certain collection function of the electric meter 330 breaks down or not can also be judged, so that maintenance personnel can maintain the electric meter more quickly and more accurately, for example, when the power terminal 310 does not receive the voltage data of the No. 1 electric meter, and the power terminal 310 can receive the forward active electric energy data, the reverse active electric energy data and the current data of the No. 1 electric meter, it is indicated that the voltage collector in the No. 1 electric meter possibly breaks down, and maintenance is needed as soon as possible.
Moreover, the communication lines used by the different electric meters 330 may be different, and as an implementation manner of the present application, the power terminal 310 is communicatively connected to the plurality of electric meters 330 through the first communication line and/or the second communication line, that is, the power terminal 310 is communicatively connected to the plurality of electric meters 330 through the first communication line, or the power terminal 310 is communicatively connected to the plurality of electric meters 330 through the second communication line, or the power terminal 310 is communicatively connected to the plurality of electric meters 330 through the first communication line and the second communication line. After the power terminal 310 is in communication connection with the plurality of electric meters 330 through the first communication line, the power terminal 310 issues the acquisition instruction to each electric meter 330 according to the first communication line and/or the second communication line.
S107-b includes:
when the acquisition instruction is issued to each electric meter according to a first communication line and first fault information is generated, the first fault information is associated with the address of the line abnormal electric meter and the first communication line fault instruction, and when the acquisition instruction is issued to each electric meter according to a second communication line and the first fault information is generated, the first fault information is associated with the address of the line abnormal electric meter and the second communication line fault instruction.
That is, in the case of the generated first failure information, the first failure information is associated with a specific communication method so that not only the detection of a failure of the communication line of the power terminal 310 or the electricity meter 330 but also the detection of a failed communication line can be specifically detected.
It is to be understood that, as one possible implementation, when the power terminal 310 is connected to the electric meter 330 through the first communication line, and when it is determined that the suspected line abnormality electric meter is a line abnormality electric meter, first fault information associated with the first communication line is generated; when the electric power terminal 310 is connected to the electric meter 330 through the second communication line and when it is determined that the suspected line abnormal electric meter is the line abnormal electric meter, first fault information associated with the second communication line is generated, when the electric power terminal 310 is simultaneously connected to the electric meter 330 through the first communication line and the second communication line, the first communication line and the second communication line are respectively tested, and when it is determined that the suspected line abnormal electric meter is the line abnormal electric meter, the first fault information associated with the first communication line and the second communication line is respectively generated, and two kinds of first fault information are generated.
As an implementation manner of the present application, the first communication line is a 485 communication line, and the second communication line is a carrier communication line.
Moreover, because the time for receiving the feedback data of the electric meter 330 is different according to the different communication lines, the step of receiving the data fed back by the electric meter 330 according to the collecting instruction and marking the electric meter 330 without the feedback data as the suspected line abnormal electric meter actually includes:
when the collection instruction is issued to each electric meter 330 according to the first communication line and the data fed back by the electric meter 330 is not received within the preset first time, the electric meter 330 without the data fed back is marked as a suspected line abnormal electric meter, and when the collection instruction is issued to each electric meter 330 according to the second communication line and the data fed back by the electric meter 330 is not received within the preset second time, the electric meter 330 without the data fed back is marked as a suspected line abnormal electric meter.
For example, taking the first communication line as a 485 communication line and the second communication line as a carrier communication line as an example, the preset first time is 3S and the preset second time is 60S.
Meanwhile, it should be noted that, if the power terminal 310 is in communication connection with one electric meter 330, and all data of the electric meter 330 are failed to be acquired, the power terminal 310 generates third fault information and reports the third fault information to the background 320, where the third fault information is related to addresses of the electric meter 330 and the power terminal 310 at the same time, that is, a maintenance person is required to check at this time to determine that the power terminal 310 is faulty or a line of the electric meter 330 is abnormal.
The following is illustrated in a specific implementation:
the power terminal 310 is connected with a plurality of electric meters 330 through a carrier and 485 communication line, a detection signal issued by the background 320 to the power terminal 310 through a network comprises a user wiring mode and a meter number, an acquisition period is 15 minutes, acquired data items are positive active electric energy, negative active electric energy, voltage and current, the power terminal 310 stores the detection signal issued by the background 320, and records the user's circuit wiring mode, the meter number, the acquisition period and acquired data. After 15 minutes, the power terminal 310 starts an acquisition task, starts to generate an acquisition instruction according to the data items configured and acquired by the background 320 to read the data of the electric meter 330, if the electric meter 330 is in a 485 connection mode, the power terminal 310 sends the acquisition instruction to the electric meter 330 through a 485 line, and if the user is in a carrier connection mode, the power terminal 310 sends the data to the electric meter 330 through the acquisition instruction.
If the sending data electric meter 330 does not reply within a specified time, for example, the 485 line waits for 3S, and the carrier line waits for 60S, the power terminal 310 considers that the data of the electric meter 330 is not collected.
