Description

Technical Field

[0001] This application relates to the technical field of Internet of Things devices, and particularly to an inspection device based on an access device. Background Art

[0002] With the popularization of communication devices, more and more field engineers can use communication terminals to record and transmit equipment inspection information. At present, the application of communication terminals by field engineers during equipment inspection still remains at recording inspection results and uploading the inspection results to the data center. Since there are many devices to be inspected, traditional devices cannot be directly linked with the communication terminals of field engineers, which results in a low correct rate of correspondence between inspection data and inspection devices, great difficulty in data sorting, and low system co-ordination and analysis capabilities for the inspected devices when field engineers later organize the inspection results. Therefore, it is necessary to propose an inspection device based on an access device to address the defect of low real-time linkage between traditional communication terminals and devices to be inspected. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The present application provides an inspection device based on an access device.

[0024] Specifically, the inspection device in the present application is an instrument used to detect whether a device is in a working state, or a device that provides communication and other services for an instrument that detects whether a device is in a working state.

[0025] The device A to be inspected is the device to be detected whether it is in a working state.

[0026] Such as Figure 1 And Figure 4 As shown in [drawings], in an embodiment of the present application, an inspection device based on an access device is provided, which is disposed on the outer peripheral surface of each device A to be inspected, and includes a substrate 100, a two-dimensional code board 200, a transparent cover plate 300, a near-field communicator 400 and a protective shell 500.

[0027] The substrate 100 is provided with a square ring groove 110.

[0028] The two-dimensional code board 200 is disposed within the surrounding range of the square ring groove 110.

[0029] The transparent cover plate 300 includes a plate body 310 and a rubber ring 320. The rubber ring 320 is clamped inside the square ring groove 110. The plate body 310 abuts against the rubber ring 320. The rubber ring 320 is disposed between the substrate 100 and the transparent cover plate 300. The two-dimensional code board 200 and the rubber ring 320 are in the same working plane.

[0030] The near-field communicator 400 is attached to the substrate 100, disposed on the side of the near-field communicator 400 away from the square ring groove 110. The near-field communicator 400 includes a memory 410 and an electronic tag 420. The memory is electrically connected to the electronic tag 420. The electronic tag 420 is attached to the substrate 100. The electronic tag 420 is disposed between the memory 410 and the substrate 100.

[0031] The protective shell 500 is fixedly connected to the substrate 100. The near-field communicator 400 is disposed inside the cavity of the protective shell 500. The protective shell 500 is attached to the outer peripheral surface of the device A to be inspected.

[0032] This application relates to an inspection device based on an access device. By using the substrate 100 to carry the QR code board 200 and the near-field communicator 400, it is beneficial for on-site engineers to use a communication terminal to obtain information of the device to be inspected before inspection, and bind the inspection result with the information of the inspected device based on the information of the device to be inspected. This greatly improves the corresponding accuracy rate of inspection data and inspection devices, reduces the difficulty of data collation, and improves the system coordination and data analysis capabilities of the inspected devices. The QR code board 200 can carry information with a large data volume. The near-field communicator 400 does not require a cellular data network. Through the low-cost QR code board 200 and near-field communicator 400, information of the inspection device can be obtained efficiently and conveniently. Based on the information of the inspection device, on-site engineers can input the corresponding inspection data into the information network of the server. The QR code board 200 and the near-field communicator 400 can also be used as an access information storage device for the device to be inspected, and the communication terminal can access the real-time information network of the server.

[0033] As Figure 2 shown, in an embodiment of the present application, the memory 410 includes a level responder 411, a digital-to-analog converter 412, and an analog-to-digital converter 413. The input end of the digital-to-analog converter 412 is electrically connected to the output end of the level responder 411. The output end of the analog-to-digital converter 413 is electrically connected to the input end of the level responder 411.

[0034] Specifically, the memory 410 stores digital quantity information through the level of the transistor inside the level responder 411. When the memory 410 receives the analog quantity signal of the electronic tag 420, the analog-to-digital converter 413 can be used to convert the analog quantity signal into a digital quantity signal, and the digital quantity signal can change the level of the transistor inside the level responder 411, thereby realizing the change of the stored digital quantity information.

[0035] The level responder 411 can also convert the digital quantity information into an analog quantity signal through the digital-to-analog converter 412, and then transmit the converted analog quantity signal through the electronic tag 420 to realize the transmission of the digital quantity information stored in the level responder 411.

[0036] As Figure 2 shown, in an embodiment of the present application, the memory 410 further includes a first mixer 415, an oscillator 416, and a filter 417. The output end of the oscillator 416 is electrically connected to the input end of the first mixer 415. The electronic tag 420 is electrically connected to the input end of the first mixer 415. The output end of the first mixer 415 is electrically connected to the input end of the filter 417. The output end of the filter 417 is electrically connected to the input end of the analog-to-digital converter 413.

[0037] Specifically, the electronic tag 420 is similar to an antenna and can receive electromagnetic wave signals. When the electronic tag 420 receives an electromagnetic wave signal, the electronic tag 420 can convert the electromagnetic wave signal into an analog signal and couple the analog signal emitted by the oscillator 416 with the analog signal of the electronic tag 420 using the first mixer 415. The filter 417 filters or notch-filters the coupled analog signal to achieve high-quality conversion of the electromagnetic wave signal or extract information in the target band of the electromagnetic wave signal. Finally, using the analog-to-digital converter 413, the analog signal is converted into a digital signal, and the digital signal can change the level of the transistors inside the level transponder 411, thereby realizing the change of storing digital information.

[0038] As Figure 2 shown, in an embodiment of the present application, the memory 410 further includes a second mixer 419. The output end of the digital-to-analog converter 412 is electrically connected to the input end of the second mixer 419. The output end of the oscillator 416 is electrically connected to the input end of the second mixer 419. The output end of the second mixer 419 is electrically connected to the electronic tag 420.

[0039] Specifically, when the memory 410 needs to send information externally, the level transponder 411 outputs a level signal to the digital-to-analog converter 412. The digital-to-analog converter 412 generates an analog signal, couples the analog signal output by the digital-to-analog converter 412 and the analog signal emitted by the oscillator 416 through the second mixer 419, and the electronic tag 420 receives the coupled analog quantity and converts the coupled analog quantity into an electromagnetic wave signal.

[0040] As Figure 1 shown, in an embodiment of the present application, the transparent cover plate 300 is provided with a square ring rib 330. The square ring rib 330 abuts against the top surface of the rubber ring 320. A buckle 340 is provided on the outer periphery of the square ring rib 330. A card hole 120 is provided on the outer periphery of the square ring groove 110 of the substrate 100. The buckle 340 is clamped in the card hole 120.

[0041] Specifically, the square ring rib 330 of the transparent cover plate 300 is engaged with the square ring groove 110 of the substrate 100, which can realize the sealing protection of the two-dimensional code plate 200 by the transparent cover plate 300. The rubber ring 320 is arranged between the square ring groove 110 of the substrate 100 and the square ring rib 330 of the transparent cover plate 300 for waterproofing. When rainwater adheres to the surface of the two-dimensional code plate 200, pollutants will be generated, affecting the expression of the two-dimensional code information on the two-dimensional code plate 200.

[0042] In an embodiment of the present application, the buckle 340 includes a vertical piece 341 and a side insertion piece 342. The vertical piece 341 is perpendicular to the transparent cover plate 300. The vertical piece 341 is fixedly connected to the transparent cover plate 300. The included angle between the side insertion piece 342 and the transparent cover plate 300 is less than 90 degrees. The side insertion piece 342 is fixedly connected to one end of the vertical piece 341 away from the transparent cover plate 300.

[0043] Specifically, the vertical piece 341 is perpendicular to the transparent cover plate 300, the included angle between the side insertion piece 342 and the transparent cover plate 300 is less than 90 degrees, and the fixedly connected vertical piece 341 and side insertion piece 342 can form a V-shaped buckle 340 structure. The tip of the buckle 340 can pass through the card hole 120 to realize the clamping of the transparent cover plate 300 and the substrate 100.

[0044] In an embodiment of the present application, the vertical piece 341 and the side insertion piece 342 have the same length.

Therefore, there will be a gap between one end of the side insertion piece 342 close to the transparent cover plate 300 and the transparent cover plate 300.

[0046] The gap between the end face of the top of the side insertion piece 342 and the transparent cover plate 300 can be adapted to the thickness of the substrate 100.

[0047] In an embodiment of the present application, the maximum vertical distance between the side of the vertical piece 341 and the side insertion piece 342 is greater than the width of the card hole 120.

[0048] The outer contour of the buckle 340 has a V-shaped structure, and there is an elastic collapse space between the vertical piece 341 and the side insertion piece 342. When the side insertion piece 342 of the buckle 340 passes through the card hole 120, the side insertion piece 342 of the buckle 340 rebounds, and the top of the side insertion piece 342 of the buckle 340 can abut against one side of the substrate 100, and this side of the substrate 100 is arranged away from the transparent cover plate 300.

[0049] As Figure 1 and Figure 3 shown, in an embodiment of the present application, a threaded hole 130 is provided on one side of the substrate 100 away from the square ring groove 110. The near-field communicator 400 is arranged within the radius range of the threaded hole 130. The side of the protective shell 500 is provided with threads. The threads are arranged away from the bottom surface of the protective shell 500. The protective shell 500 is threadedly connected to the threaded hole 130.

[0050] Specifically, the threaded hole 130 provided on the side of the substrate 100 away from the square ring groove 110 is used to connect the protective shell 500. There are many electronic components inside the near-field communicator 400, and the protective shell 500 can provide waterproof protection.

[0051] In an embodiment of the present application, a gasket ring 140 is provided at the bottom of the threaded hole 130. The gasket ring 140 is disposed between the bottom of the threaded hole 130 and the protective shell 500.

[0052] Specifically, the gasket ring 140 is disposed between the bottom of the threaded hole 130 and the protective shell 500, which can improve the waterproof ability of the protective shell 500.
