Abstract
Description
Technical Field
[0001] The invention relates to the field of induction type electric energy meters, and in particular to a monitoring content control system for induction type electric energy meters. Background Art
[0002] The induction energy meter is a high-function energy meter, and its main components include drive elements, voltage coils, current coils, etc. The measurement of electric energy should not only reflect the size of the load power, but also reflect the time of power usage. Therefore, the meter used to measure electric energy, in addition to having a mechanism for measuring power, should also be able to calculate the time the load uses electricity, and automatically accumulate the electric energy through an accumulation mechanism. In order to drive the accumulation mechanism to work, the meter must overcome the friction of each link of the transmission mechanism, so the measuring mechanism is required to have a large torque.
[0003] In engineering, degrees or kilowatt-hours are often used as units of electrical energy. Therefore, the instrument that measures electrical energy is called an energy meter or a kilowatt-hour meter. The electric energy meter made of an electric measuring mechanism is only used in DC circuits due to its complex structure and process and high cost. The measurement of AC power uses an inductive measuring mechanism. This measuring mechanism has a large torque and low cost. The inductive energy meter made of it is widely used in the production and transmission of electrical energy, industrial and agricultural production departments, and household users. Therefore, this is the most used and widely used electrical instrument.
[0004] When performing visual monitoring processing on the inductive power meter to obtain and output the current monitoring image corresponding to the current timestamp, it is necessary to perform intra-frame encoding on the current monitoring image, such as intra-frame compression, and then transmit the intra-frame encoded data. Obviously, the performance of intra-frame encoding directly determines the quality and restoration of the monitoring image after subsequent reception and reconstruction by the remote data receiving end. What is particularly critical is that the monitoring screen is only interested in a part of the screen area, namely the screen imaging area. Therefore, the encoding algorithm used in intra-frame encoding needs to match the imaging characteristics of the screen imaging area to ensure the encoding performance and restoration effect of the key position of the screen imaging area. Summary of the invention
[0005] In order to solve the technical problems in related fields, the present invention provides an inductive electricity meter monitoring content control system, which can determine the size of the intra-frame coding block that is monotonically inversely associated with the content complexity value of the screen imaging area according to the content complexity value of the screen imaging area, wherein the larger the content complexity value of the screen imaging area is, the smaller the determined intra-frame coding block that is monotonically inversely associated with the content complexity value of the screen imaging area is, thereby adaptively selecting different intra-frame coding strategies according to the different complexities of the imaging areas of key components, thereby improving the flexibility and intelligence level of intra-frame coding.
[0006] According to the present invention, a monitoring content control system for an inductive electric energy meter is provided, the system comprising: A visual monitor is arranged opposite to the inductive energy meter, and is used to perform visual monitoring processing on the inductive energy meter when the inductive energy meter is in an activated state, so as to obtain and output a current monitoring image corresponding to a current timestamp; A step-by-step enhancement device is arranged inside the inductive electric energy meter and is wirelessly connected to the visual monitor, comprising a first enhancement component, a second enhancement component and a third enhancement component, and is used to continuously perform an affine transformation operation, an image content enhancement operation using a logarithmic transformation and a linear grayscale transformation operation on the received current monitoring image to obtain and output a corresponding step-by-step enhanced image; A screen identification device connected to the step-by-step enhancement device, used to identify an imaging area corresponding to the liquid crystal display screen of the inductive energy meter from the received step-by-step enhancement image based on the brightness value distribution characteristics corresponding to the liquid crystal display screen of the inductive energy meter, and output it as a screen imaging area; An information measuring mechanism, connected to the screen identification device, is used to obtain the brightness values corresponding to the pixels of the received screen imaging area, and output the mean square error of the brightness values as the content complexity value of the screen imaging area; A parameter conversion mechanism, connected to the information measurement mechanism, for determining, based on the received content complexity value of the screen imaging area, the size of the intra-frame coding block that is monotonically inversely correlated with the content complexity value of the screen imaging area; Wherein, determining the size of the intra-frame coding block monotonically inversely associated with the content complexity value of the screen imaging area according to the received content complexity value of the screen imaging area comprises: the larger the received content complexity value of the screen imaging area is, the smaller the determined intra-frame coding block monotonically inversely associated with the content complexity value of the screen imaging area is; Wherein, determining the size of the intra-frame coding block that is monotonically inversely correlated with the content complexity value of the screen imaging area according to the received content complexity value of the screen imaging area further comprises: using an information conversion function to represent the information conversion relationship between the determined size of the intra-frame coding block and the content complexity value of the screen imaging area; Among them, the information conversion relationship in which the size of the determined intra-frame coding block and the content complexity value of the screen imaging area are monotonically inversely correlated using an information conversion function includes: in the information conversion function, the size of the determined intra-frame coding block is the output information, and the content complexity value of the screen imaging area is the input information.
[0007] It can be seen that the present invention has at least the following three significant substantive features: Substantive feature 1: A visual monitor is arranged opposite to the inductive energy meter, and is used to perform visual monitoring processing on the inductive energy meter when the inductive energy meter is in an activated state, so as to obtain and output a current monitoring image corresponding to a current timestamp, and a step-by-step enhancement device with a customized structural design including a first enhancement component, a second enhancement component and a third enhancement component is used to continuously perform an affine transformation operation, an image content enhancement operation using a logarithmic transformation and a linear grayscale transformation operation on the received current monitoring image, so as to obtain and output a step-by-step enhanced image with higher imaging quality; Substantive feature 2: Based on the brightness value distribution characteristics corresponding to the LCD screen of the inductive energy meter, the imaging area corresponding to the LCD screen of the inductive energy meter is identified from the received step-by-step enhanced image as the screen imaging area. More importantly, the brightness values corresponding to the respective pixel points of the received screen imaging area are obtained, and the mean square error value of the brightness values is output as the content complexity value of the screen imaging area; Substantive feature three: The size of the intra-frame coding block that is monotonically inversely correlated with the content complexity value of the screen imaging area is determined according to the content complexity value of the screen imaging area, wherein the larger the content complexity value of the screen imaging area is, the smaller the intra-frame coding block that is determined to be monotonically inversely correlated with the content complexity value of the screen imaging area is, thereby adaptively selecting different intra-frame coding strategies according to the different complexities of the imaging areas of key components, thereby improving the flexibility and intelligence level of intra-frame coding.
[0008] The inductive electric energy meter monitoring content control system of the present invention operates intelligently and has wide applications. Since the size of the intra-frame coding block that is monotonically inversely related to the content complexity value of the screen imaging area can be determined according to the content complexity value of the screen imaging area, different intra-frame coding strategies can be adaptively selected according to the different complexities of the imaging area of the key components, thereby improving the flexibility and intelligence level of the intra-frame coding.
