Description

Technical Field

[0001] This utility model relates to the technical field of septic tank management equipment, and in particular to a septic tank ID card code collection and recognition device. Background Technology

[0002] In the field of urban environmental sanitation management, the effective maintenance and precise management of septic tanks are crucial for ensuring urban public health. The septic tank identification code, as a key carrier uniquely identifying the septic tank's identity information and maintenance status, is constantly exposed to complex outdoor environments. Inevitably, factors such as dust accumulation and surface wear make it difficult for ordinary handheld scanning devices to fully read the information. This results in the management system being unable to accurately obtain the current maintenance status of the septic tank, causing numerous inconveniences to environmental sanitation management work.

[0003] To address the identification issues caused by surface contamination of the carrier, existing technologies utilize dust brushes to clean the surface of the ID card carrier in septic tanks on-site, facilitating convenient and accurate information reading. However, in practical applications, such data collection and identification devices still suffer from the following technical shortcomings that urgently need to be addressed:

[0004] Firstly, in strong light environments such as direct sunlight, the display screen of handheld data collection and recognition devices is prone to glare, resulting in a blurry image. This forces staff to frequently adjust the device angle or search for shaded areas, severely impacting the efficiency of the scanning operation and increasing on-site work time costs.

[0005] Secondly, the scanning camera of existing equipment is usually fixed on the bottom of the equipment. When it is necessary to scan the ID code of the septic tank, the operator has to perform a large-scale rotation of the equipment. This results in a large intersection angle between the equipment screen and the human eye's field of vision, which makes it very inconvenient for the operator to confirm the scanning status in real time and is prone to misjudgment and other problems.

[0006] Third, in low-light environments, operators find it difficult to quickly and accurately determine the specific location of the septic tank's ID code, and lack effective means to align the code with the scanning area. They often need to spend a lot of time exploring and adjusting, resulting in excessively long scanning times and seriously affecting the smoothness of the workflow.

[0007] In view of this, the inventor has designed a septic tank ID card code collection and recognition device, which leads to this invention. Utility Model Content

[0008] To solve the above problems, the technical solution of this utility model is as follows:

[0009] A septic tank ID card code collection and recognition device includes a device body, a display screen is provided on the front side of the device body, a scanning component is provided on the rear side of the device body, the scanning component includes a camera module, an auxiliary crosshair module and a supplementary light module, a light shield is detachably provided on the rear side of the device body, and a plug-in structure is provided on the front side of the device body that is detachably connected to the light shield.

[0010] Preferably, the light-shielding plate is in the shape of a straight plate, and the rear side of the main body of the equipment is provided with a hidden groove that slides and fits into the light-shielding plate, and the light-shielding plate and the hidden groove are engaged with each other.

[0011] Preferably, the light-shielding plate has a protruding insertion edge at one end along its length, and the side wall of the hidden groove has a slot that engages with the insertion edge.

[0012] Preferably, the plug-in structure is a strip structure with a semi-circular cross-section, and includes fixed seats at both ends along its length and a plug-in body disposed between the fixed seats. The plug-in body is recessed inward to form clearance grooves distributed along its length. The inner bottom of the clearance groove is arc-shaped and two plug-in grooves with different angles to its circle are formed along its arc-shaped surface. The plug-in grooves can be fitted and connected with the plug-in edge to form different covering angles between the light shield and the display screen.

[0013] Preferably, the extension length of the insertion slot is greater than the width of the display screen.

[0014] Preferably, an RFID read / write module is provided on the rear side of the main body of the device, near the scanning component.

[0015] Preferably, the upper edge of the RFID reading and writing module forms an inclined connecting surface with the top of the device body, and the scanning component is disposed on the connecting surface.

[0017] Preferably, the side wall of the main body of the device is provided with a QR code scanning button for activating the camera module, an auxiliary button for activating the auxiliary crosshair module, and a fill light button for activating the fill light module.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes a detachable light-shielding plate integrated on the rear of the device body, combined with a plug-in structure design on the front, to flexibly adjust the shading according to lighting conditions. This effectively avoids screen glare caused by direct sunlight, eliminating the need for operators to frequently search for shaded areas or adjust the device angle. This significantly reduces operating time costs in strong light environments and ensures the continuity of the scanning process. Simultaneously, through a built-in supplementary lighting module and auxiliary crosshair module, a precise recognition system is constructed under low-light conditions: the supplementary lighting module provides uniform illumination, solving the problem of difficult scanning area positioning in low-light environments; the laser crosshair projection function enables rapid alignment, avoiding the inefficient operation of traditional equipment that relies on experience, shortening scanning time, and significantly improving work efficiency in complex lighting environments.

[0020] In addition, by tilting the connection surface of the camera module, the camera maintains a certain tilt angle with the device body and the screen, which allows users to easily align the camera component with the septic tank ID code to be scanned with minimal sway, thereby helping users to easily confirm the scanning status and improving the efficiency of septic tank ID code scanning.

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] Please see Figures 1 to 6 This is a preferred embodiment of the present invention, a septic tank ID card code collection and recognition device, including a device body 100, a display screen 200 on the front side of the device body 100, a scanning component 300 on the rear side of the device body 100, the scanning component 300 including a camera module 310, an auxiliary crosshair module 320 and a supplementary light module 330, a light shield 110 detachably provided on the rear side of the device body 100, and a plug-in structure 400 detachably connected to the light shield 110 on the front side of the device body 100.

[0033] Specifically, such as Figure 2 , 3 As shown, the light shield 110 is in the shape of a straight plate. The rear side of the main body 100 of the equipment is provided with a hidden groove 120 that slides and fits into the light shield 110. The light shield 110 and the hidden groove 120 are engaged. One end of the light shield 110 along its length direction is provided with an insertion edge 111. The side wall of the hidden groove 120 is provided with a slot that engages with the insertion edge 111.

[0034] Thus, the light shield 110 can be easily pushed in and hidden through the hidden slot 120, so that when the light shield 110 is not needed, it forms a complete whole with the entire device body 100, and can also be easily removed when light protection is required.

[0035] Preferred, such as Figure 1 , 4As shown in Figure 5, the plug-in structure 400 is a strip structure with a semi-circular cross-section, and includes a fixing seat 410 located at both ends of its length direction and a plug-in body 420 disposed between the fixing seats 410. The plug-in body 420 is recessed inward to form a relief groove 430 distributed along its length direction. The inner bottom of the relief groove 430 is arc-shaped and two plug-in grooves 440 are formed at different angles with its circle along its arc surface. The plug-in grooves 440 can be fitted and connected with the plug-in edge 111 so that different covering angles are formed between the light shield 110 and the display screen 200.

[0036] In this embodiment, the arc formed by the inner bottom of the clearance groove 430 is concentrically set with the semi-circular shape of the insertion body 420, and the insertion groove 440 is radially distributed along the center of the arc. In this embodiment, there are two insertion grooves 440, which correspond to different included angles of 30° and 60° respectively. When the insertion edge 111 of the light shield 110 is inserted into the slot, it forms an included angle of 30° or 60° with the display screen 200, thereby facilitating the formation of light shielding for the display screen 200.

[0037] Preferably, the extension length of the insertion slot 440 is greater than the width of the display screen 200, and the two sides of the light shield 110 are adapted to the two sides of the insertion slot 440, so that the light shield 110 can cover the position beyond the left and right edges of the display screen 200, forming a larger covering area and further improving the light shielding effect.

[0038] Preferred, such as Figure 2 , 4 As shown, an RFID read / write module 500 is protruding from the rear of the main body 100 and near the scanning component 300. Correspondingly, a passive RFID tag is set on the carrier of the septic tank ID code. Through read / write operations, each septic tank inspection can be recorded, and the current status of the septic tank can be displayed for convenient management. At the same time, the protruding RFID read / write module 500 can be easily misaligned with the camera module 310, so that the RFID read / write module 500 on the rear of the main body 100 can more easily contact the plane containing the RFID tag for read / write operations.

[0039] Preferred, such as Figure 2 , 4 As shown, an inclined connecting surface 130 is formed between the upper edge of the RFID read / write module 500 and the top of the device body 100, and the scanning component 300 is disposed on the connecting surface 130. In this embodiment, the angle formed between the connecting surface 130 and the surface of the RFID read / write module 500 is 150°.

[0040] Therefore, by tilting the connection surface 130 of the camera module 310, the camera maintains a certain tilt angle with the device body and the screen, which allows users to easily align the camera component with the septic tank ID code to be scanned with minimal sway, thereby helping users to easily confirm the scanning status and improving the efficiency of septic tank ID code scanning.

[0041] Preferably, the auxiliary sight module 320 is a red laser sight that can project a crosshair laser spot, and the supplementary light module 330 is an LED bead with a color temperature of 4000-5000K. This color temperature range is close to natural light, which can truly restore the color and details of the septic tank ID card code, avoid image color distortion caused by color temperature deviation, and help improve the recognition accuracy of the camera module 310.

[0042] Preferably, the side wall of the device body 100 is provided with a barcode scanning button 340 for activating the camera module 310, an auxiliary button 350 for activating the auxiliary crosshair module 320, and a fill light button 360 for activating the fill light module 330.

[0043] In addition, such as Figure 6 As shown, the device also has a built-in control module 600, which is a control circuit board and uses an STM32F4 series microcontroller.

[0044] The connection method between the control circuit board and each module is as follows:

[0045] The control module 600 (control circuit board) built into the device serves as the core hub, connecting with other modules through circuit lines, including:

[0046] The control module 600 is connected to the display screen 200 on the front of the main body 100 via a data transmission line. It processes the image data of the septic tank's ID code collected by the camera module 310 and the septic tank status information read by the RFID reader / writer module 500, and then transmits this data to the display screen 200 for visualization. Simultaneously, the control module 600 also adjusts the display parameters of the display screen 200 (such as brightness and contrast) to adapt to different lighting conditions.

[0047] The control module 600 is connected to the camera module 310 via a data cable and is used to control the camera's start-up, shutdown, focus adjustment, and shooting parameter settings. The image data of the septic tank ID code captured by the camera is transmitted back to the control module 600 via the data cable, where the control module 600 performs image recognition and data parsing.

[0048] The control module 600 is connected to the auxiliary sight module 320 (laser sight) via a circuit. When the operator presses the auxiliary button 350 on the side wall of the main body 100 of the equipment, the control module 600 receives the button signal and controls the auxiliary sight module 320 to project a red cross-shaped laser spot through the circuit, providing alignment assistance for the scanning operation.

[0049] The control module 600 and the supplementary light module 330 are connected by a circuit. When the supplementary light button 360 is pressed, the control module 600 receives the instruction and drives the supplementary light module 330 to turn on, providing illumination for the scanning area in low light environment. At the same time, the brightness of the supplementary light module 330 can be adjusted by the control module 600 according to the ambient light intensity.

[0050] The control module 600 is connected to the RFID reader / writer module located near the scanning component 300 on the rear side of the main body 100 via a dedicated communication line. The control module controls the RFID reader / writer module to read and write passive RFID tags on the objects carrying the septic tank's identification codes. Data such as septic tank inspection records and status acquired by the RFID reader / writer module is transmitted to the control module 600 via the communication line for processing and storage, and is simultaneously displayed on the display screen 200.

[0051] The barcode scanning button 340, auxiliary button 350, and fill light button 360 on the side wall of the main body 100 are integrated into a button module, which is connected to the control module 600 through a circuit. When the operator presses the button, the resulting electrical signal is transmitted to the control module 600 through the circuit. The control module 600 executes corresponding control commands according to different button signals, such as starting the camera module 310, activating the auxiliary crosshair module 320, and turning on the fill light module 330.

[0052] The beneficial effects of this utility model are as follows:

[0053] This invention utilizes a detachable light shield 110 integrated into the rear of the main body 100, combined with a front-mounted plug-in structure 400. This allows for flexible adjustment of the shielding according to lighting conditions, effectively avoiding screen glare caused by direct sunlight. This eliminates the need for operators to frequently search for shaded areas or adjust the equipment angle, significantly reducing operating time costs in strong light environments and ensuring the continuity of the scanning process. Simultaneously, the built-in supplementary lighting module 330 and auxiliary crosshair module 320 construct a precise recognition system under low-light conditions: the supplementary lighting module 330 provides uniform illumination, solving the problem of difficult positioning of the scanning area in low-light environments; the laser crosshair projection function enables rapid alignment, avoiding the inefficient operation of traditional equipment that relies on experience, shortening scanning time, and significantly improving work efficiency in complex lighting environments.

Obviously, the specific implementation of the present invention is not limited to the above-described manner.
