Description

Technical Field

[0001] The utility model relates to the technical field of electricity consumption reading of electric meters, in particular to a non-invasive electric meter electricity consumption metering device. Background Technique

[0002] With the rapid development of technology, the intelligent technology of the old electric meters in the power plants built at the beginning of the 21st century has fallen behind the development of the times. Therefore, for these old electric meters, a series of transformations are undoubtedly required to carry out more efficient management. To get rid of the time-consuming and laborious method of going to the site to read the electric meter readings every month in the past, it is necessary to consider how to wirelessly transmit the electric meter readings. The main transformation methods for the current old electric meters are as follows:

[0003] (1) Replace the old electric meter with the current new type of electric meter. The new type of electric meter has a built-in wireless transmission function. For this method, first, it is necessary to apply to the local power supply bureau for replacement, and electrical appliances cannot be used during the replacement of the electric meter, which is very inconvenient. It not only has a large time cost but also needs to pay the cost of installing a new electric meter, resulting in greater losses for users.

[0004] (2) Some enterprises may use an invasive method to interact with the old electric meter to obtain the data in the electric meter. This method is very undesirable. Since the management of electric meters in China is very strict at present, the act of privately modifying the electric meter is illegal. Therefore, although this method is convenient, it is the most undesirable.

[0005] In recent years, the number of old electric meters in power plants that need to be transformed has been increasing. Among them, the traditional method of consuming manpower to read the electric meter readings should be eliminated in today's society. From the defects of the above methods, it can be seen that when transforming the old electric meters in power plants, it should be possible to make the cost lower while not affecting the normal use of users, and a non-physical contact and non-invasive method should be used to complete the transformation without any physical contact with the old electric meters and without data interaction with the old electric meters. From these two requirements, it is necessary to propose a new type of device to make the transformation of old electric meters in power plants efficient, safe and low-cost. Summary of the Invention

The utility model mainly uses a support mechanism, a rotation mechanism, a sampling mechanism and a lighting mechanism to complete the installation of the device without replacing the electric meter, which is convenient for reading the electricity consumption displayed on the electric meter.

[0007] The technical means adopted by the utility model are as follows:

[0032] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0034] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary embodiments of the present invention. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of the described features, steps, operations, devices, components and / or their combinations.

[0035] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0037] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0038] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stated, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0052] Embodiment 1

[0053] As Figure 1 shown, the present invention provides a non-invasive electric meter power consumption measurement device. In this embodiment, the structure of the PCB board 7 during specific implementation is provided, as Figure 2 shown.

[0054] Figure 2Among them, the STM32HX7xx single-chip microcomputer 14, as the main controller of the embedded system, integrates various software functions such as operating systems and communication protocol stacks, and controls and processes various input and output devices such as sensors and actuators to achieve data acquisition functions. The LED lamp 15 is used to display various states of the embedded device, such as whether it is in the power-on state and whether the algorithm has been downloaded completely, etc., for indication functions. The SD card 16 mainly saves the pictures taken by the camera. At the same time, because of its small size, light weight and pluggable characteristics, it is convenient to replace when the capacity is insufficient, ensuring that there is enough capacity to save pictures. The USB interface 17 is mainly used to supply power to the embedded device, and at the same time can be used to connect to a computer to deploy the algorithm into the embedded device.

The LCD / WIFI module 19, the LCD can be used to display various types of images, charts, texts and videos. The WIFI module is used to ensure that when the embedded device is connected to a computer, the pictures taken on-site can be uploaded to the computer. The 32-BIT SDRAM module 20 has the ability of high-speed data storage and reading and writing, and is mainly used to store the target detection algorithm. The camera 8 is an image sensor connector module, which mainly transmits the collected image data to the image processor on the circuit board, facilitating the algorithm to perform derivation processing on the picture. The camera is connected to the circuit board through this module.

[0055] Embodiment 2

[0056] As Figure 1 shown, on the basis of Embodiment 1, the embedded device of the present utility model that deploys a high-performance target detection algorithm can simulate the human eye using the principle of machine vision, and obtain the reading of the electric meter without contacting the electric meter, so as to judge the monthly power consumption of the user.

[0057] The metering device deploys an embedded device with a high-performance target detection algorithm, and designs a reasonable and effective way to install the embedded device in a suitable position parallel to the electric meter so that it can work properly. To obtain the most core embedded device, it mainly includes the following steps: constructing a data set of electric meter readings; selecting a suitable target detection algorithm for training; selecting a suitable device and deploying the trained detection algorithm into the device to obtain the final embedded device.

[0058] The data set of electric meter readings serves as a sample, that is, to let the subsequent target detection algorithm know which targets it needs to be interested in and perform detections accordingly. To obtain the correct data set, first, about 400 photos of electric meter readings on-site need to be collected, and the pictures are labeled using a suitable website or software. After completion, a data set that can be used for algorithm training is obtained.

[0059] The meaning of selecting a suitable object detection algorithm is that due to the rapid development of object detection in recent years, more and more high-performance algorithms have been proposed. However, these excellent algorithms have the problem that the file volume containing the training results is too large, making it difficult to find a suitable device to deploy the algorithm. Therefore, it is necessary to select a suitable object detection algorithm in engineering. In this embedded device, a FOMO model improved based on the MobileNetV2.0 algorithm proposed by Google is selected. The improved algorithm has a smaller volume of training results and a faster detection speed compared to the original one.

[0060] The significance of selecting a suitable device to deploy the algorithm is to select a device that meets the engineering purpose. Since this metering device is designed based on the principle of machine vision, a device with a camera needs to be selected so that it can capture the on-site electricity meter and transmit it to the detection algorithm for inference. Therefore, the device selected this time is an embedded device with a single-chip microcomputer as the control chip and a camera to deploy the algorithm to meet the actual needs.

[0061] Compared with the traditional method, the advantages of this method are as follows:

[0062] (1) Using the 4G network to wirelessly transmit the monthly electricity consumption of users is more convenient and faster than the traditional manual reading, reducing labor costs.

[0063] (2) When transforming the old electricity meters in the power plant, it is not necessary to replace the new electricity meters to complete this intelligent and information-based transformation. It is convenient to install, has a lower cost, and the detection effect is very effective.

[0064] (3) There is no physical contact between this metering device and the old electricity meters, and there is no data interaction with the old electricity meters. It uses a non-invasive method to transmit the electricity meter data to the upper computer platform.

[0065] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
