Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The invention provides an electric energy meter display detection method, an electric energy meter display detection device, an electric energy meter and a medium, which are used for solving the technical problems of inaccurate and incomplete detection of display content of a liquid crystal display screen of the existing electric energy meter.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
It should be noted that, in the existing verification technology of the liquid crystal display of the electric energy meter, because the electric energy meter has multiple conditions of automatic cycle display, key cycle display, self-checking display and the like, if the manual detection method is relied on, the coverage and accuracy of the detection are difficult to be ensured. The detection efficiency and the accuracy of the liquid crystal display screen in the industry are low at present due to the environmental factors and the state of the electric energy meter. Because the accuracy of the mode of detecting by the camera is low, and meanwhile, the electric energy meter has automatic circulation display, the shot images are difficult to ensure to be clearly matched with the expected images, certain requirements on the shooting angle, the shooting frequency and the like of the camera are met, and the implementation difficulty is high. The invention provides an electric energy meter display detection method aiming at the problem of low detection efficiency and accuracy of an electric energy meter liquid crystal display, wherein fig. 1 is a display interface of a single-phase intelligent electric energy meter provided by the embodiment of the invention, and fig. 2 is a display interface of a three-phase intelligent electric energy meter provided by the embodiment of the invention, as shown in fig. 1 and 2, the electric energy meter can be applied to the single-phase intelligent electric energy meter, the three-phase intelligent electric energy meter and the like, and the electric energy meter is not limited herein.
Fig. 3 is a flowchart of a method for detecting display of an electric energy meter according to an embodiment of the present invention, as shown in fig. 3, where the method includes:
s11: receiving a display command issued to the electric energy meter, wherein the display command is a custom command and represents a display field corresponding to display information of the electric energy meter;
s12: acquiring actual display information of the current electric energy meter according to the display command;
s13: comparing the actual display information with preset display information to determine and display a detection result;
the preset display information is obtained through an operation command, the operation command is a user-defined command and represents ideal display fields corresponding to the display information of the electric energy meter, and the display fields corresponding to the actual display information and the preset display information are in one or more display field combination forms.
Specifically, a display command issued to the electric energy meter is received, wherein the display command is a display command correspondingly displayed by a liquid crystal display screen under the control of a micro control unit (Microcontroller Unit, MCU) system of the electric energy meter. The display command in this embodiment is a custom command, and is based on a display field corresponding to display information of the electric energy meter, and the display field is used to indicate that different display fields can form a message form of the custom command.
And acquiring actual display information of the current electric energy meter according to the display command, namely acquiring the actual display content of the current electric energy meter through the display command, wherein the actual display information is identical with the preset display information if the display detection is correct. The corresponding preset display information may be directly obtained through other commands, or may be directly called through pre-storing the preset display information in a certain database, which is not limited herein.
And comparing the actual display information with preset display information to determine a display detection result. The comparison process may be that if the actual display information is different from the preset display information, the comparison is failed, and the display detection result is abnormal. The delay condition can also be considered when the display information is acquired, so that the actual display information is acquired for multiple times, for example, 3 times of actual display information is acquired within 5 seconds, different conditions can exist in the 3 times of actual display information, and the current detection result can be determined to be normal only if one or more pieces of actual display information are the same as the preset display information, and the satisfied times can be determined according to the actual conditions.
The comparison process can be directly executed through the program of the script file of the electric energy meter, or two display information of the script file can be obtained and then stored in a data file for additional comparison. The present invention is not limited to this, and may be compared according to actual conditions. The preferred embodiment is executed directly by a pre-stored script file program in the electric energy meter to improve the detection efficiency.
In the conventional detection method, if the scene that the switching-off lamp is turned on and the date and time are displayed at the same time is required to be detected, a remote tripping command and a display checking command are required to be issued to the electric energy meter, so that a plurality of instructions are acquired, the detection procedure is complicated, as an embodiment, the preset display information is acquired through an operation command, wherein the operation command is a self-defined command and represents an ideal display field corresponding to the display information of the electric energy meter, and the display field forms corresponding to the actual display information and the preset display information are in one or more display field combination forms.
It can be understood that the preset display information is obtained by the operation command, and the operation command issued to the electric energy meter controls the liquid crystal display of the electric energy meter to display the contents of a certain field or the combination of a plurality of fields at regular time, so that the display information is not limited by the state of the electric energy meter and the automatic cycle display. In the prior art, only a fixed field, such as "electricity consumption", is selected for the fields, and three fields need to be displayed simultaneously.
