Description

Technical Field

[0001] This utility model relates to the field of gas equipment technology, and more specifically, to a display device that flexibly displays gas meter icon information. Background Technology

[0002] With the widespread application of smart gas meters in residential and industrial sectors, gas companies have increasingly diversified functional requirements for these meters, demanding more information from them. However, due to cost constraints, existing smart gas meters generally use segment display screens rather than dot matrix screens. Therefore, the icons on the display screen cannot be changed after the design is completed, and they can only display basic Chinese information or related icons, such as remaining gas volume, cumulative gas consumption, unit price, and various alarm information. However, different gas companies have different needs for the information displayed on gas meters in different scenarios. For example, for residential users, gas companies may be more concerned with real-time gas usage rates to better understand gas safety and stability; while for industrial users, gas companies may need to display parameters such as pressure and temperature to accurately control gas equipment and achieve gas load balance. Furthermore, as gas meters become more intelligent, the amount of information available is increasing. However, the domestic gas industry has not yet established a unified standard for this, which has exacerbated the differences in the requirements of gas companies for the content displayed on the gas meter window. The existing fixed icon display method in the segment code screen can no longer fully meet this requirement. If a segment code screen is customized and developed for each gas company, it will also result in a waste of R&D human resources, material costs, and time.

[0003] In view of this, the present invention provides a display device for flexibly displaying gas meter icon information to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Please see Figure 1 This utility model provides a technical solution: a display device that flexibly displays gas meter icon information, a housing body 1 and a display space 2 disposed on the housing body 1, the display space 2 being sealed on the housing body 1 by an encapsulation housing 3, and a connector 4 being disposed on the top of the housing body 1;

[0019] The display space 2 includes a gas remaining display area 21, a text indicator area 22, and an arrow icon area 23, wherein:

[0020] The gas balance display area 21 and the arrow icon area 23 are connected to the smart motherboard 5 via wires. The smart motherboard 5 is installed inside the outer casing 1. The modified text information in the text indicator area 22 is updated in the firmware of the smart motherboard 5. The content to be displayed is marked by the arrow icon area 23 using the software control system commonly used by gas companies, and the gas balance is displayed based on the gas balance display area 21. This control method is existing technology and will not be described in detail here.

[0021] Furthermore, since the gas balance display area 21 and the arrow icon area 23 require a certain display space, while the text indicator area 22 only needs to be printed on its surface, a wiring groove is provided in the housing corresponding to the text indicator area 22 to reduce the space occupied by the display device content and save space layout to a certain extent; making the internal space layout of the housing body 1 more reasonable.

[0022] Furthermore, a locking component 11 is provided on the inner side of the gas remaining display area 21 and the arrow icon area 23 respectively. The locking component 11 has an open window in the middle for displaying the gas remaining display area 21 and the arrow icon area 23. The corresponding accessories of the gas remaining display area 21 and the arrow icon area 23 are installed in the positioning groove.

[0023] The card slot component 11 combines the arrow icon in the arrow icon area 23 with the corresponding silkscreen printed icon information in the text indicator area 22 to meet the differentiated needs of different regions and gas companies. The arrow icon area 23 is designed with only arrow icons to indicate different information, achieving high flexibility and versatility. The arrow icon design is simple and intuitive, allowing users to quickly understand the current status or indication information. The icon information on the plastic shell is clearly visible, avoiding the problem of overly complex display screen content.

[0024] Additionally, the mounting component 11 secures the gas balance display area 21 and the arrow icon area 23 to the main body 4 of the casing, making it suitable for various gas meter application scenarios and meeting the differentiated needs of different regions and gas companies. If the display requirements of the gas company change, only the firmware needs to be updated and the icons on the plastic casing re-engraved. There is no need to redesign or replace the display hardware; only the silkscreen and firmware configuration of the plastic casing need to be adjusted, reducing inventory pressure. Manufacturers only need to store universal segment code screens and plastic casings.

[0025] Furthermore, the gas balance display area 21 and the arrow icon area 23 are preferably segment display screens. The reason for choosing segment display screens is that they offer low power consumption, low cost, high reliability, ease of control, and clear display, making them particularly suitable for devices requiring long-term operation and displaying simple information. Although they cannot display complex graphics or animations, they are a very practical and efficient choice in gas meter applications.

[0026] Further explanation of the functions of each part within display space 2; among which:

[0027] Gas balance display area 21 is a dedicated area for displaying the gas balance, usually in digital form. The gas balance display area 21 is independently set at the top of the display space 2 to help users quickly obtain key information.

[0028] The text indicator area 22 is used to display various status indicator icons, such as abnormality, overdraft, and battery level. The icon information is printed on the plastic casing by silkscreen printing, which can flexibly adapt to the requirements of different gas companies and reduce the complexity of hardware design.

[0029] Arrow icon area 23: Arrow icons are used to point to different icon information corresponding to the text indicator area 22 on the plastic shell, and are fixed inside the text indicator area 22; using arrow icons simplifies hardware requirements, and can adapt to different display requirements by updating firmware, thereby improving production flexibility and efficiency.

[0030] This embodiment can quickly adapt to the display requirements of different gas companies through silkscreen printing and firmware updates, without the need to redesign the hardware. Functional adjustments can be achieved through firmware updates, reducing the difficulty of maintenance and upgrades.

[0031] Example 2

[0032] Please see Figure 2 This embodiment, based on embodiment 1, provides a method for flexibly displaying gas meter icon information, including the following steps:

[0033] Based on a general design scheme, a fixed arrow icon is configured on the segment code screen;

[0034] Configure custom icon information according to the target design scheme, and print the icon information on the plastic shell using silkscreen technology;

[0035] By updating the firmware, the position and direction of the arrow icon can be flexibly adjusted to adapt to the target design requirements of different gas companies.

[0036] Specifically, the icon information required by the gas company is screen-printed onto the plastic casing surrounding the display screen, while the segment display only features arrow icons to indicate different icon information. In other words, the general design uses the most common arrow icons currently on the market, while the target design uses the icon information required by the gas company. This design scheme, which uses fixed arrow icons on the segment display and prints the icon information using screen printing technology, is highly innovative, achieving high versatility and adaptability through an innovative, separate design.

[0037] Meter manufacturers only need to provide a segment display screen. To meet the display requirements of different gas companies, the necessary icon information is engraved onto different locations on the plastic casing during the production stage using a laser printer. The firmware in the smart meter's mainboard is then updated, causing the arrow icon on the segment display to point to different icons engraved on the plastic casing in different application scenarios. This overcomes the limitations of existing smart gas meters in terms of information display and reduces the development costs and time required to customize display content for different gas companies.

[0038] This design flexibly displays different icon information according to the needs of different gas companies, improving the ease of use and information display efficiency of gas meters. It also reduces the R&D costs and time for meter manufacturers. By separating the display content icons from the indicator arrow icons, it breaks away from the traditional model of content-hardware binding in display screen design. This separate design significantly improves the versatility of the hardware. If new icon information needs to be added, only the silkscreen printing plate needs to be redesigned and the firmware updated; no hardware design changes are required. Users can quickly understand the current status or indicator information. The arrow icon design is simple and clear, avoiding the problem of overly complex content in traditional displays.

[0039] Specifically, examples of the application of the target design scheme in practical applications include:

[0040] Gas type indication:

[0041] The plastic casing is silkscreened with icons such as "natural gas" and "liquefied petroleum gas," with arrows pointing to the type of gas currently in use.

[0042] Status indication:

[0043] The casing is silkscreened with icons such as "normal", "fault", and "undervoltage", with arrows pointing to the current status.

[0044] Alarm information:

[0045] The casing is silkscreened with icons such as "leakage" and "overpressure," with arrows pointing to the current alarm information.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.

[0047] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
