It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Please refer to fig. 1, which is a flowchart illustrating an electric meter maintenance method according to an embodiment of the present disclosure. The electric meter maintenance method can comprise the steps S102-S106.
Step S102, detecting whether an infrared meter reading button of a meter reading terminal is pressed down, if so, acquiring the current meter reading data of the meter reading terminal; the electric meter data comprises electric meter position data and electric meter wiring data.
Specifically, the meter reading terminal can be a meter reading machine, the meter reading machine is a meter reading machine provided with an infrared meter reading button, the electric meter can be a three-phase four-wire electric meter, and electric meter data read by the meter reading machine can comprise electric meter position data and electric meter wiring data; the ammeter position data can comprise ammeter longitude and latitude data and user data corresponding to the ammeter; specifically, the user data corresponding to the electric meter mainly refers to information such as a house name, a house number, a cell and the like of a user using the electric meter, namely specific location information, and the longitude and latitude data of the electric meter mainly refers to rough range data. The electricity meter wiring data comprises a power factor and/or a phase angle; that is, the meter wiring data may include a power factor, a phase angle, and both a power factor and a phase angle.
And step S104, comparing and analyzing the acquired ammeter wiring data with preset standard wiring data, and judging whether the wiring of the ammeter is wrong or not.
Specifically, the phase angle and the power factor are used as main parameters capable of reflecting whether the wiring mode is wrong, and whether the wiring of the ammeter is wrong or not can be judged by directly obtaining numerical values and then comparing the numerical values with preset or prestored standard numerical values. It can be understood that the judgment between the phase angle and the power factor and the preset standard wiring data can be performed by referring to the existing manner, and further details are not described herein.
And S106, responding to the situation that the wiring of the ammeter is wrong, and sending the ammeter position data of the ammeter to terminal equipment of operation and maintenance personnel.
Specifically, if the connection of the ammeter is judged to be wrong, namely when the obtained phase angle or power factor is compared and analyzed with preset standard data and does not accord with the set conditions, the ammeter position data of the ammeter with the wrong connection are sent to the terminal equipment of operation and maintenance personnel; the terminal equipment can be a smart phone or a tablet computer; further, the ammeter position data of the ammeter with the wrong wiring are sent to the terminal equipment of the operation and maintenance personnel by firstly sending the ammeter position data to the background management center and then forwarding the ammeter position data to the corresponding terminal equipment of the operation and maintenance personnel by the background management center. Further, the electric meter position data of the electric meter is sent to terminal equipment of operation and maintenance personnel, and meanwhile, a warning signal is sent out. The warning signal may be a visual or audible based warning signal, which may be generated by a buzzer, and a visual warning signal, which may be generated by an LED.
In one embodiment, the electric meter maintenance method of the present application may further include the steps of:
and responding to the fact that the wiring of the electric meter is not wrong, and updating the electric meter data recorded before with the electric meter data acquired this time.
Specifically, if the wiring of the electric meter is found to be not wrong after the comparison and analysis, the electric meter data acquired this time can be updated to the electric meter data recorded before, that is, the old data is updated by the newly acquired data, and the recorded data is guaranteed to be the latest detection data all the time.
In one embodiment, the electric meter maintenance method of the present application may further include the steps of:
and detecting whether the time for acquiring the electric meter data is within a preset time range, and if not, judging that the current electric meter is an abnormal electric meter.
Specifically, when a meter reader presses an infrared meter reading button, namely an infrared signal is sent to the electric meter, at the moment, whether data return exists from the electric meter or not is synchronously detected, in addition, the time is kept under the condition that no data return exists, the time is stopped when the data return exists or the time for time keeping exceeds a preset time range, and if the time for obtaining the electric meter data exceeds the preset time range, the current electric meter is judged to be an abnormal electric meter, namely the data cannot be transmitted to the meter reading machine. In this case, the information of the abnormal electricity meter should be recorded, and the information may be sent to the background management center when necessary, and the background management center distributes the operation and maintenance personnel. Optionally, the preset time range of the present application may be 15s-20 s; more optionally, the preset time range is 20 s.
Further, in a traditional meter reading mode, a meter reader can directly input data to a meter reading machine through manual operation, in this case, the meter reader does not need to go to the site, however, most of the data input in this mode is estimated by the meter reader according to experience, which is often inaccurate, and meanwhile, the position of the electric meter cannot be located and collected, and the situation that the electric meter is unwilling to occur is not provided for a power supply company or a user, and in order to monitor the meter reading quality (mainly referring to estimation and false reading) of the meter reader, the electric meter maintenance method of the application can further include the steps of:
shooting the abnormal electric meter and uploading the abnormal electric meter to a background management center;
and after the uploading is successful, jumping to a manual electric meter data input interface.
That is to say, according to the method and the device, when the time for acquiring the electric meter data exceeds the preset time range, the electric meter is judged to be an abnormal electric meter, the electric meter data can not be transmitted to a meter reading machine, under the condition, a meter reading person needs to shoot the abnormal electric meter and upload the abnormal electric meter to a background management center, then the current interface for automatically inputting the electric meter data is switched to a manual electric meter data inputting interface, and the condition that the meter reading person conducts data estimation and reading on the electric meter when the meter reading person does not arrive at the site can be avoided. Meanwhile, the background management center can assign operation and maintenance personnel to the site to maintain and replace the abnormal electric meter according to the feedback information.
According to the ammeter maintenance method, the data of the ammeter can be timely sent to the terminal equipment of operation and maintenance personnel when the wiring of the ammeter is wrong, the situations that a meter reader estimates and copies the data and even manually copies the data in the field can be avoided, and the meter reading quality is guaranteed.
