[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0036] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a gas remote intelligent control device, including a metering module 1. A control display module 2 is connected to one side of the metering module 1. A side groove 3 is opened on one side of the control display module 2, and a card slot is opened on one side of the inner wall of the side groove 3. A card 4 is inserted into the card slot. A protective device 5 is provided in the side groove 3. The protective device 5 includes two movable grooves 506. A movable block 505 is slidably connected in the movable grooves 506. The same protective plate 503 is connected to one side of the two movable blocks 505. A first spring 507 is connected to one side of the movable blocks 505.

[0037] Furthermore, the end of the first spring 507 away from the moving block 505 is connected to one side of the inner wall of the moving groove 506, and the moving groove 506 is opened on one side of the inner wall of the side groove 3.

[0038] Furthermore, the protective plate 503 is attached to and slidably connected to the inner walls of the side groove 3 on both sides, and one side of the protective plate 503 is in contact with one side of the inner wall of the side groove 3.

[0039] Furthermore, the movable block 505 is embedded with a sliding sleeve, and a support rod 504 is slidably connected inside the sliding sleeve. The two ends of the support rod 504 are respectively connected to the two sides of the inner wall of the movable groove 506, and the first spring 507 is sleeved on the outside of the support rod 504.

[0040] Furthermore, an extension groove 502 is provided on one side of the protective plate 503, and an extension plate 501 is slidably connected in the extension groove 502. One side of the extension plate 501 is connected to one side of the inner wall of the side groove 3.

[0041] Furthermore, a lever is connected to one side of the protective plate 503, and a latching groove is provided on one side of the lever.

[0042] The specific implementation method is as follows: By setting up a protective device 5, by moving a lever to one side, the lever causes the protective plate 503 to move to one side. The movement of the protective plate 503 causes the moving block 505 to move, which in turn compresses the first spring 507, causing the first spring 507 to contract and generate a rebound force. A support rod 504 is set up to support the first spring 507, preventing the first spring 507 from bending during compression and affecting its rebound effect. Then, after inserting the card 4 into the card slot, the lever is released, allowing the moving block 505 to reset and move due to the rebound force of the first spring 507. This causes the moving block 505 to move the protective plate 503 to reset and move, thereby sealing the side slot 3 where the card 4 is inserted. This prevents damage to the card 4 and card slot caused by high temperature, humidity, oil fumes, steam, etc., thus preventing damage to the card 4 from affecting the gas meter. The accuracy of metering is ensured by connecting one side of the extension plate 501 to one side of the inner wall of the side groove 3, allowing the extension plate 501 to slide within the extension groove 502. This allows the extension plate 501 to shield the first spring 507 and the moving groove 506, thus preventing the rebound force of the first spring 507 from being affected by oil and gas adhesion. The control display module 2 is equipped with a crystal oscillator circuit, a reset circuit, a battery voltage detection circuit, a FLASH memory, a FRAM memory, a real-time clock circuit, a Bluetooth circuit, a communication module, a valve switch control module, and a pulse signal acquisition module. This technology is existing and does not require a detailed description of the connection and operation process. Through the internal electronic components, the gas meter can be remotely and intelligently controlled via the control display module 2, achieving accurate metering, remote management and control, and user self-service, thereby improving gas management efficiency and user service experience. Example 2

[0043] Reference Figures 4-5 In the second embodiment of this utility model, a force-applying contact device 6 is provided on one side of the inner wall of the card slot into which the card 4 is inserted. The force-applying contact device 6 includes a fixing block 601. A movable groove 602 is provided on one side of the fixing block 601. A contact block 603 is slidably connected in the movable groove 602. Two allowance grooves 606 are provided on one side of the contact block 603. A second spring 605 is connected to one side of the allowance groove 606.

[0044] Furthermore, the fixing block 601 is embedded in one side of the inner wall of the slot, and the other end of the second spring 605 is connected to one side of the inner wall of the movable slot 602.

[0045] Furthermore, one side of the card 4 is provided with an end piece 8, and one side of the contact block 603 is connected to a contact copper piece 7, with one side of the contact copper piece 7 abutting against the corresponding side of the end piece 8.

[0046] Furthermore, a fixing groove 607 is provided on one side of the excess groove 606, and a fixing rod 604 is slidably connected in the fixing groove 607. The other end of the fixing rod 604 is connected to one side of the inner wall of the movable groove 602, and the second spring 605 is sleeved on the outside of the fixing rod 604.

[0047] The specific implementation method is as follows: By setting up a force-applying contact device 6, during the process of inserting the card 4 into the card slot, one side of the card 4 contacts the inclined surface of the contact block 603, causing the inclined surface of the contact block 603 to move inward under force. The movement of the contact block 603 compresses the second spring 605, causing the second spring 605 to compress and generate a rebound force. By setting up a margin groove 606, there is enough space for the second spring 605 to be compressed. Subsequently, after the card 4 is inserted into place, the rebound force of the second spring 605 drives the contact block 603 to move in the opposite direction, thereby causing the contact block 603 to drive the contact copper piece 7 to contact the end piece 8 on one side of the card 4, thus avoiding the gap between the contact copper piece 7 and the end piece 8 caused by long-term insertion and removal, which would affect signal transmission.

[0048] Working principle: In use, the metering module 1 is connected to the gas pipe through the inlet and outlet pipes. Then, by moving the lever to one side, the lever moves the protective plate 503 to one side, causing the protective plate 503 to move the moving block 505. This causes the moving block 505 to compress the first spring 507, which in turn generates a rebound force. The movement of the protective plate 503 exposes the slot in the side groove 3, and then the card 4 is inserted into the slot. The card 4 presses against the contact block 603 on one side, causing the contact block 603 to move inward. This causes the contact block 603 to press the second spring 605, causing the second spring 605 to generate a rebound force. When the card 4 is inserted into place, the contact block 603, through the rebound of the second spring 605, causes the contact copper piece 7 to fit tightly with the end piece 8. Then, the push block is released, causing the moving block 505 to drive the protective plate 503 to reset and move through the rebound force of the first spring 507. This allows the protective plate 503 to block the card 4 and the card slot in the side groove 3, thereby preventing oil and gas from entering and damaging the card 4, which would affect the metering and deduction.
