Detailed implementation manners
[0034] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. Hereinafter, the present utility model will be described in detail with reference to the drawings and in combination with the embodiments.
[0035] As Figure 1 shown, the present embodiment discloses a camera meter reading device, including:
[0036] A bottom shell 4, disposed on the meter dial to be read;
[0037] A main housing 1, welded to the bottom shell.
[0038] Specifically, the material of the main housing 1 is entirely transparent polycarbonate (PC plastic). To meet the manual meter reading requirements of the original meter, transparent PC plastic is used. Among them, the meter to be read can be a dial mechanical water meter. Welding can integrate the main housing 1 and the bottom case into a whole, improving the stability of the camera-based meter reading device.
[0039] The main housing 1 includes a battery compartment and a main cavity;
[0040] As Figure 4 shown, the battery compartment is used to install a cylindrical lithium thionyl chloride battery, and a waterproof silicone strip is installed in the groove on the edge of the battery compartment lid 9 of the battery compartment.
[0041] Specifically, the battery in the battery compartment can be manually replaced when the battery power is too low. The function of the waterproof battery compartment is to prevent damage to the battery in a humid environment and avoid the situation of insects nesting in an enclosed space. Among them, the cylindrical lithium thionyl chloride battery can adapt to a wider temperature range and has a more stable working voltage. The waterproof silicone strip can prevent the battery compartment from getting water in a humid environment and improve the sealing performance of the battery compartment.
[0042] Please continue to refer to Figure 5 and Figure 6 , Figure 5 which are the front view of the circuit board, Figure 6 and
[0043] The device in the embodiment of the present application has a circuit board 10, which is installed inside the main cavity. The circuit board 10 includes a main control MCU, a spring antenna 108, and a camera. Among them, the main control MCU can control the camera to take a picture of the dial to obtain the image of the meter to be read and upload the image of the meter to be read to the server through the communication module.
[0044] Specifically, the main control MCU uses a mature processing unit in the prior art and has a function of initiating timed photography. After the photography time arrives, the main control MCU drives the camera to obtain the original image data. At the same time, the main control MCU lights up the fill light LED to assist in night photography. The original image data is processed by a compression algorithm to form a JPEG format picture, and the data is sent to the server through the NB-IoT communication module. If the signal is poor during data upload, it will retry two more times after a 10-minute interval. If all three attempts fail, the main control MCU will store the data in the data memory, and then re-upload the data to the server platform when the next timing arrives. If the data is in a state of being unable to be uploaded for a long time, all the data will be saved in the data memory, and at most 100 picture data can be saved.
[0045] As Figure 3 shown, an antenna protection cover 8 is provided on the main cavity for placing the spring antenna 108.
[0046] Specifically, the antenna protective cover 8 is used to protect the internal spring antenna 108 and ensure the safety of the spring antenna 108 during operation.
[0047] Furthermore, by providing a detachable battery compartment lid 9, the battery can be replaced when the device battery power is too low.
[0048] In some embodiments of the present application, a product identification plate 2 is also provided on the main cavity.
[0049] Specifically, information such as the brand, production time, and manufacturer are marked on the product identification plate to show the brand of the device.
[0050] In some embodiments of the present application, the protruding portion of the main housing 1 is provided with a mounting hole 3.

[0052] In some embodiments of the present application, the camera is a 30W camera and is electrically connected to the main control MCU using an FPC connector.
[0053] The FPC connector is an electronic device with high density and small size, and is used to connect a flexible cable to a circuit on the circuit board.
[0054] Specifically, the main control MCU of the circuit board 10 uses an MCU with Bluetooth communication function, and cooperates with a 30W pixel camera to take pictures of the digital display area of the meter, and uploads the compressed JPG format pictures to the cloud using NB-IoT communication for subsequent functions such as image recognition, data analysis, and storage on the cloud server.
[0055] In some embodiments of the present application, the surface of the main housing 1 opposite to the battery compartment is an inclined surface, and the inclined surface is a viewing window 7, and the inclined surface has a 35° angle with the plane of the main housing 1.
[0056] Specifically, in this embodiment, a large viewing window 7 is reserved on the housing. After installing the device, it does not affect the manual meter reading of the original meter. When this device is installed above the dial of a dial-type mechanical water meter, data can be collected by taking pictures at regular intervals. The original image data is processed by a compression algorithm to form JPEG format pictures, and the data can be sent to the server platform through the NB-IoT communication module.
[0057] In some embodiments of the present application, there is a protruding direction calibration line 6 on the viewing window 7.
[0058] Specifically, the direction calibration line calibrates the direction of the visible window, and is mostly used during installation to prompt the installer of the installation direction.
[0059] In some embodiments of the present application, as Figure 2 shown, the shape of the bottom case is square or circular.
[0060] Specifically, the bottom of the main housing 1 provides bottom cases with two different bottom surfaces, a circular bottom case and a rectangular bottom case. The circular bottom case is mostly used for mechanical water meters and mechanical pressure gauges, and the rectangular bottom case is mostly used for electric meters and gas meters. The two different shaped bottom cases basically meet the transformation requirements of most traditional mechanical meters.
[0061] In some embodiments of the present application, the bottom case includes three welded fusion lines, and the bottom case is welded to the main housing 1.
[0062] Optionally, the main housing 1 and the bottom case can be welded by ultrasonic means.
[0063] In some embodiments of the present application, the spring antenna 108 is an antenna with communication function.
[0064] Specifically, the spring antenna 108 can cooperate with the communication module for data communication and send JPEG format pictures to the server platform.
[0065] The beneficial effects of the present application are as follows:
[0066] 1. The present utility model provides an independent battery compartment with an independently powered battery inside, ensuring that the device can work stably for a long time; the battery compartment lid 9 is detachable, facilitating battery replacement when the battery power of the device is too low, and a waterproof silicone strip is provided in the groove on the edge of the battery compartment lid 9, having a good waterproof effect.
[0067] 2. The present utility model provides an antenna protection cover on the main cavity, providing an accommodation space for the spring antenna on the circuit board and providing a good protection effect.
[0068] 3. The present utility model can automatically and regularly capture images of the meter to be read through the main control MCU, spring antenna and camera on the circuit board.
[0069] The working principle of this embodiment can be:
[0070] The staff installs the present utility model above the meter to be read through the installation hole 3. The 30W camera 104 takes timed automatic photos of the digital information area of the meter to be read. The NB-IoT communication module 107 uploads the taken pictures to the server platform. The antenna protection cover 8 protects the spring antenna 108 with communication function. When it is necessary to inspect the water meter on site, the staff can observe and record through the visual window 7. The staff can also replace the power supply battery by removing the battery compartment cover 9.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present utility model can still be modified or equivalently replaced, and any modification or equivalent replacement that does not depart from the spirit and scope of the present utility model should be covered within the protection scope of the claims of the present utility model.
