Description

Technical Field

[0001] This invention relates to the field of data acquisition terminal testing technology, specifically a modular data acquisition terminal testing device. Background Technology

[0002] Currently, data acquisition terminal testing devices simulate various power consumption environments and power faults to establish a simulated environment of on-site conditions, monitoring various responses of the data acquisition terminals to accurately assess the functions and performance of the terminals under test. This helps ensure that the data acquisition terminals can operate stably and accurately in practical applications, providing strong support for the intelligent management of power systems. The data acquisition terminal testing device is required to automatically calibrate the measurement accuracy of the AC sampling circuit of the terminal under test (energy meter). During calibration, an automatic output short circuit is implemented to ensure no induced signal, thus guaranteeing calibration accuracy. The calibration process can complete items such as voltage accuracy, current accuracy, and transformer phase shift in one step, and automatically records equipment that cannot be calibrated.

[0003] In existing data acquisition terminal testing devices, all energy meter testing modules are fixed within the device. When one of these modules malfunctions, the entire circuit board needs to be disassembled, resulting in lengthy troubleshooting time and inconvenient operation during the testing process. This fails to meet the operational requirements of data acquisition terminal testing. Therefore, a modular data acquisition terminal testing device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a modular data acquisition terminal detection device to solve the technical problems of inconvenient disassembly and assembly and long troubleshooting time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular data acquisition terminal detection device, comprising a chassis, wherein a worktable is mounted on the lower front side of the chassis. The chassis has a first functional area on the left side and a second functional area on the right side. An energy meter detection module is inserted into the second functional area. The energy meter detection module includes a housing and an end cover. A data port is provided on one side of the back of the housing, and a power socket is provided on the other side of the back of the housing. First rollers are hinged to both sides of the lower part of the housing, and second rollers are hinged to both sides of the lower part of the housing at the side positions of the first rollers. The diameter of the first roller is larger than that of the second roller. Each end cover is provided with a card seat on the upper side of its front surface. Each card seat is provided with a toothed plate, and the bottom end of each toothed plate is connected to a mounting plate. A fixing member is installed on the lower side of the front surface of the end cap. A probe assembly is installed on the top of the fixing member. A first movable cavity is opened on the upper side of the inside of the fixing member. A second movable cavity is opened on the lower side of the first movable cavity.

[0006] Preferably, a partition is installed in the middle of the inner cavity of the second functional area. The size of the upper and lower cavities of the second functional area separated by the partition is adapted to the height of the energy meter detection module. By dividing the second functional area spatially by the partition, the installation size of the detection module can be accurately adapted, and the module can be limited and regulated to avoid loosening or displacement during installation. At the same time, the utilization rate of cavity space is optimized, ensuring the installation stability and adaptability of the detection module.

[0007] Preferably, the first functional area is equipped with a control module, which is a computer system. The first functional area is installed on the side close to the power source. Placing the control module with the computer system close to the power source can shorten the signal and power transmission path, reduce signal interference and loss during transmission, improve the overall control response efficiency of the device, and ensure accurate and stable operation of the detection operation.

[0008] Preferably, both the first roller and the second roller are covered with rubber sleeves. The first roller is located at the bottom middle of the housing, and the second roller is located at the bottom rear end of the housing. The rubber sleeves on the outside of the rollers can play the roles of anti-slip, shock absorption, and noise reduction. The reasonable roller distribution structure can balance the force on the housing, making the push-pull movement of the detection module smoother and more stable.

[0009] Preferably, the depth of the second movable cavity is less than the depth of the first movable cavity, and an outer membrane is laid on the side wall of the second movable cavity. The outer membrane extends to the highest point of the first movable cavity. The opening of the first and second movable cavities facilitates the insertion and removal of the energy meter detection module by inserting a finger, while the outer membrane increases the friction.

[0010] Preferably, the energy meter detection module is equipped with a Bluetooth communication unit, an RS485 communication unit, an error processing unit, and an HPLC communication unit. The integration of multiple types of communication and processing units enriches the data transmission and processing functions of the device, can adapt to data interaction in various communication scenarios, autonomously completes detection error correction, and greatly improves the accuracy and versatility of detection data.

[0011] Preferably, a drive motor is installed on the back of the end cover. The outer end of the rotor of the drive motor passes through the interior of the card holder. A gear is coaxially connected to the outer end of the rotor of the drive motor, and the gear meshes with a gear plate. The motor, in conjunction with the meshing transmission structure of the gear and the gear plate, can realize the automatic lifting and adjustment of the mounting plate, improve the adjustment accuracy and work efficiency, and ensure the standardization and consistency of detection and positioning.

[0012] Preferably, the card holder and the fixing component are both installed on the central axis of the end cover. A sliding groove is provided in the middle of the front surface of the end cover. A slider is connected to the back of the mounting plate at the position corresponding to the sliding groove. The central axis layout ensures that the component is installed with uniform force. The cooperation structure of the sliding groove and the slider plays a guiding and limiting role for the mounting plate, making its lifting and lowering operation more stable and effectively avoiding deviation and jamming.

[0013] Preferably, the cross-section of the slide groove and the slider is a convex shape, the four corners of the mounting plate are provided with through holes, and the outer corners of the mounting plate are provided with rounded corners. The convex shape can improve the fit between the slider and the slide groove, and the anti-disengagement and limiting effect is better. The through holes facilitate the assembly and fixing of components, and the rounded corner design can avoid bumps and damage, thus improving the safety and ease of assembly of the equipment.

[0014] Preferably, each toothed plate has an insert connected inside. The height of the insert is the same as that of the toothed plate. The insert is inserted into the inner wall of the card holder. The insert is T-shaped. The T-shaped insert is precisely inserted into the inner wall of the card holder, which can effectively strengthen the toothed plate mounting structure, improve the stability of the toothed plate during transmission, prevent the toothed plate from shifting or loosening, and ensure the continuous and stable operation of the gear transmission structure.

[0015] Compared with the prior art, the present invention provides a modular acquisition terminal detection device, which has the following beneficial effects: This modular data acquisition terminal testing device, through the independent energy meter testing module inserted within the second functional area, allows for direct insertion and removal of individual energy meter testing modules, facilitating easy replacement without disassembling the entire circuit board. This enables faster troubleshooting and repair. Furthermore, because the outer diameter of the first roller is larger than that of the second roller, it is easier to use the other hand to pull out the energy meter testing module by one end and then support it from the bottom. This is especially convenient when pulling out the energy meter testing module located at the bottom of the chassis near the workbench, enhancing the overall ease of operation of the testing device.

[0018] This invention provides a technical solution: a modular data acquisition terminal detection device, comprising a chassis 1, a workbench 2, a first functional area 3, a second functional area 4, an energy meter detection module 5, a housing 51, an end cap 52, a mounting base 6, a fixing component 7, a first movable cavity 71, a second movable cavity 72, an outer membrane 73, a probe assembly 8, a first roller 9, a second roller 10, a data port 11, a power socket 12, a toothed plate 13, a mounting plate 14, a drive motor 15, a gear 16, an insert 17, a slide groove 18, and a slider 19. Please see Figure 1 A workbench 2 is installed on the lower front side of the chassis 1. A first functional area 3 is located on the left side of the interior of chassis 1, and a second functional area 4 is installed on the right side. An energy meter testing module 5 is installed inside the second functional area 4. The energy meter testing module 5 contains a Bluetooth communication unit, an RS485 communication unit, an error processing unit, and an HPLC communication unit. Please refer to [link / reference needed]. Figure 2 The electricity meter detection module 5 includes a housing 51 and an end cap 52. Please refer to [link / reference]. Figure 3 A data port 11 is provided on one side of the back of the housing 51, and a power socket 12 is provided on the other side of the back of the housing 51. Please refer to [link / reference]. Figure 2 The lower two sides of the housing 51 are hinged with first rollers 9, and the lower two sides of the housing 51 are hinged with second rollers 10 at the side positions of the first rollers 9.

[0019] The diameter of the first roller 9 is larger than that of the second roller 10. A retainer 6 is installed on the upper side of the front surface of the end cover 52. (See also...) Figure 5 Each card holder 6 has a toothed plate 13 inserted inside, and each toothed plate 13 has a mounting plate 14 connected to its bottom end. Please refer to [link / reference]. Figure 2 A retainer 7 is mounted on the lower side of the front surface of the end cap 52, and a probe assembly 8 is mounted on the top of the retainer 7. Please refer to [link / reference]. Figure 4The upper side of the fixed part 7 has a first movable cavity 71, and the lower side of the first movable cavity 71 has a connected second movable cavity 72. The independent energy meter detection module 5 inserted in the second functional area 4 allows for direct insertion and removal of a single energy meter detection module 5, facilitating direct replacement without disassembling the entire circuit board of the device. This makes troubleshooting and maintenance faster. Furthermore, since the outer diameter of the first roller 9 is larger than that of the second roller 10, it is easier to use the other hand to pull out the energy meter detection module 5 by supporting it from the bottom after pulling out one end. This is especially convenient when pulling out the energy meter detection module 5 located at the bottom of the chassis 1 near the workbench 2, thus improving the ease of operation of the detection device.

[0020] The inner cavity of the second functional area 4 is equipped with a partition. The size of the upper and lower cavities of the second functional area 4 separated by the partition is adapted to the height of the electricity meter detection module 5. The first functional area 3 is equipped with a control module. The control module adopts a computer system. The computer system includes a computer with an Intel Core i5 12th generation or higher processor, 8GB DDR4 or higher memory, and a 1TB or higher 7200 RPM SATA hard drive. It also includes a wired keyboard and mouse. The first functional area 3 is installed on the side close to the power source. The first roller 9 and the second roller 10 are both covered with rubber sleeves. The first roller 9 is located at the bottom middle of the housing 51, and the second roller 10 is located at the bottom rear end of the housing 51.

[0021] Please see Figure 4 The depth of the second movable cavity 72 is less than the depth of the first movable cavity 71. An outer membrane 73 is laid on the side wall of the second movable cavity 72, extending to the highest point of the first movable cavity 71. When the electricity meter detection module 5 is damaged and needs to be disassembled, simply unplug and plug the wires and data cable, insert your finger along the first movable cavity 71 into the second movable cavity 72, lift the electricity meter detection module 5, and use the fact that the outer diameter of the first roller 9 is larger than the outer diameter of the second roller 10 to pull the electricity meter detection module 5 out in an inclined position. This makes pulling out easier and allows the other hand to support and remove the module after pulling it out a certain distance. Please refer to [link to relevant documentation]. Figure 6 The back of the end cap 52 is equipped with a drive motor 15, and the outer end of the rotor of the drive motor 15 penetrates the interior of the card holder 6. Please refer to [link / reference]. Figure 7 The rotor of the drive motor 15 is coaxially connected to a gear 16, which meshes with the gear plate 13. The mounting bracket 6 and the fixing member 7 are both mounted on the central axis of the end cover 52. (See also...) Figure 7A groove 18 is provided in the middle of the front surface of the end cap 52. Sliders 19 are connected to the back of the mounting plate 14 at positions corresponding to the groove 18. Both the groove 18 and the sliders 19 have a convex cross-section. Through holes are provided at the four corners of the mounting plate 14, and rounded corners are provided at the outer edges of the mounting plate 14. Please refer to [link / reference]. Figure 8 Each toothed plate 13 has an insert 17 connected inside. The height of the insert 17 is the same as that of the toothed plate 13. The insert 17 is inserted into the inner wall of the card holder 6. The insert 17 has a T-shaped structure.

[0022] This solution utilizes an independent energy meter testing module 5 inserted within the second functional area 4, allowing for direct insertion and removal of a single energy meter testing module 5. This facilitates direct replacement without disassembling the entire circuit board, enabling faster troubleshooting and repair. Furthermore, the addition of a first roller 9 with a larger outer diameter than the second roller 10 allows for easier removal by pulling out one end of the energy meter testing module 5 with the other hand. This is particularly convenient when pulling out the energy meter testing module 5 located at the bottom of the chassis 1 near the workbench 2, enhancing the overall ease of operation of the testing device.
