Description

Technical Field

[0001] This utility model relates to the field of inspection devices, and in particular to an industrial Internet of Things sensor inspection device. Background Technology

[0002] Inspection refers to the process of regularly or irregularly checking and reviewing equipment, systems, or the environment to ensure their normal operation and to promptly identify potential problems or anomalies. Currently, inspections typically include visual inspection, auditory inspection, and tactile inspection. Visual inspection mainly involves observing the appearance and operating status of the equipment to look for signs of abnormality; auditory inspection involves listening to the sounds of the equipment operating to determine if there is any abnormal noise; and tactile inspection involves touching the surface of the equipment to sense whether its temperature is normal.

[0003] Currently, a Chinese utility model patent with publication number CN208812102U and publication date of May 3, 2019, proposes an inspection robot, including a communication device for receiving inspection tasks; a navigation device connected to the communication device for generating a movement route; and a drive device connected to the navigation device for carrying the business device to the inspection location.

[0004] When in use, the flow inspection robot can automatically generate an inspection route without relying on existing tracks, relying on communication and navigation devices, and then carry out inspections along the generated route by its drive device.

[0005] Regarding the aforementioned technologies, when inspecting sensors using robots or relying on manual inspection, the inspection can only rely on visual judgment of the sensor's appearance. This makes it impossible to effectively detect the working status of IoT sensors, resulting in the difficulty in detecting performance degradation or circuit failures in IoT sensors, which affects normal production operations. Utility Model Content

[0006] To improve the reliability of detecting the working status of IoT sensors during inspections, this utility model provides an industrial IoT sensor inspection device.

[0007] This utility model provides an industrial Internet of Things (IoT) sensor inspection device, which adopts the following technical solution:

[0008] An industrial IoT sensor inspection device includes: a housing, a display screen, control buttons, a detection mechanism, a controller, and a power supply. The display screen and control buttons are mounted on the housing, while the detection mechanism, controller, and power supply are installed inside the housing. The display screen, control buttons, and detection mechanism are all electrically connected to the controller, which is also electrically connected to the power supply. The detection mechanism includes a detection chamber, a generator, and a data interface. The detection chamber is fixedly mounted on the housing, the generator is installed inside the detection chamber, and the data interface is fixedly mounted on the housing. Both the generator and the data interface are electrically connected to the controller.

[0009] By adopting this technical solution, when testing sensors, the sensor probe is first placed in the testing chamber, and the sensor's data cable and data interface are electrically connected. Then, the control button is adjusted to switch the controller to the testing mode corresponding to the sensor type. The environment inside the testing chamber is altered by a control generator, placing the sensor probe in a changing environment. Since the sensor's data cable or data interface is electrically connected to the controller and screen, the sensor's status parameters can be directly observed on the screen. Changes in these status parameters indicate whether the sensor is in normal working condition, thus enabling the detection of the sensor's operating status. Therefore, during the inspection of IoT sensors, in addition to inspecting the sensor's appearance, its operating status and parameters can also be detected, further reducing the probability of sensor malfunctions and improving the reliability of the inspection work.

[0010] Optionally, the generator includes a connector, a heating element, a humidifying element, and a blowing element. The connector is fixedly connected to the detection chamber, and the heating element, the humidifying element, and the blowing element are arranged on the connector. The heating element, the humidifying element, and the blowing element are electrically connected to the controller.

[0011] By adopting this technical solution, the heating element, humidifying element, and blowing element can be used to increase the temperature of the air in the detection chamber, increase the humidity of the air in the detection chamber, and decrease the temperature and humidity in the detection chamber while increasing the air flow rate in the detection chamber. In this way, when the sensor is being detected, the generator can be controlled by the controller to quickly change the environment inside the detection chamber, and the temperature sensor, humidity sensor, and flow sensor can be detected separately, thus improving the applicability of the inspection device when detecting different sensors.

[0012] Optionally, a reference sensor is also installed inside the detection chamber. The reference sensor is fixedly mounted on the housing, and its probe is located inside the detection chamber. The reference sensor is electrically connected to the controller.

[0013] By adopting this technical solution, a reference sensor is installed inside the testing chamber. When testing the sensor under test, the parameters of the sensor under test are compared with those of the reference sensor. If the parameters of the sensor under test deviate from the parameters of the reference sensor by more than a set threshold, it proves that the sensor under test may be faulty. If the parameters deviate within the set threshold range, it proves that the sensor under test is in normal working condition. In this way, the sensor status can be judged by numerical comparison, which can more directly show whether the sensor is in normal working condition.

[0014] Optionally, a switching mechanism is also installed on the housing. The switching mechanism includes a movable part and multiple protruding parts. The movable part is rotatably mounted on the housing. The movable part is provided with multiple mounting holes. The multiple protruding parts are respectively disposed inside the multiple mounting holes. The detection chamber is also provided with protruding holes. The positions of the protruding holes correspond to the mounting holes. Multiple reference sensors are provided. The multiple reference sensors are respectively disposed inside the multiple mounting holes. The reference sensors are fixedly connected to the end of the protruding part near the mounting hole.

[0015] By adopting this technical solution, multiple different types of sensors can be installed on the switching mechanism. When testing the sensors, the movable part can be adjusted to switch the reference sensor to the same state type as the sensor to be tested, according to the type of the sensor to be tested. The extension part is then moved to extend the corresponding reference sensor from the mounting hole and through the extension hole. After using the reference sensor, the extension part and the reference sensor are retracted into the mounting hole. In this way, when multiple reference sensors are installed on the switching mechanism, the reference sensors that are not used can be moved out of the detection chamber, saving space inside the detection chamber. At the same time, it can also prevent the probability of collision between sensors causing damage.

[0016] Optionally, the switching mechanism is further provided with elastic elements that correspond one-to-one with the protruding members. The elastic elements are disposed between the protruding members and the movable members, and the elastic elements have a tendency to move the protruding members away from the protrusion holes.

[0017] By adopting this technical solution, the telescopic component and the reference sensor can be automatically retracted into the mounting hole when the reference sensor is not needed or after use, reducing the probability of forgetting to retract the reference sensor after use.

[0018] Optionally, the switching mechanism further includes a first driving member, a second driving member, and a transmission member. The first driving member and the second driving member are fixedly mounted on the housing. The first driving member and the movable member are connected in a transmission manner. The second driving member and the transmission member are connected in a transmission manner. The transmission member is slidably disposed on the housing. The transmission member is correspondingly disposed with the mounting hole of the movable member. Both the first driving member and the second driving member are electrically connected to the controller.

[0019] By adopting this technical solution, the first driving component can drive the movable component to rotate on the housing, and the second driving component can drive the transmission component to slide on the housing and push the protruding component out from the mounting hole towards the protruding hole. In this way, the switching of the reference sensor can be completed by controlling the first driving component and the second driving component, which improves the automation level of the IoT sensor inspection device and reduces the operation difficulty for the staff.

[0020] Optionally, the inner wall of the mounting hole is further provided with a support member, which is arranged circumferentially along the inner wall of the mounting hole, and the support member is made of a flexible material.

[0021] By adopting this technical solution, the support component can support the reference sensor. After the sensor inspection device falls or is involved in a collision, the support component can protect it, reduce the probability of the sensor being damaged by collision with the inner wall of the mounting hole, and improve the service life of the reference sensor.

[0022] Optionally, a water-absorbing element is also provided on the inner ring of the protruding hole. The water-absorbing element is arranged in a ring on the inner ring surface of the protruding hole, and the inner diameter of the water-absorbing element is the same as the outer diameter of the reference sensor.

[0023] By adopting this technical solution, when the water-absorbing component passes over the protrusion hole of the reference sensor, it will wipe the outer wall of the reference sensor, reducing the likelihood that the reference sensor will bring moisture back to the mounting hole when the humidity inside the detection chamber is high, and will still be in a state of high humidity when used again, which will affect the measurement accuracy.

[0024] Optionally, a sealing cover is provided at the end of the detection chamber near the housing, the sealing cover is slidably mounted on the housing, and the sealing cover is snapped onto the detection chamber.

[0025] By adopting this technical solution, the detection chamber can be opened by sliding the sealing cover during use, and the sensor to be tested can be inserted into the detection chamber. After using the detection chamber, the sealing cover can be slid to lock the sealing cover onto the detection chamber. This can reduce the amount of dirt entering the detection chamber, protect the detection chamber, and extend the service life of the IoT detection device.

[0026] Optionally, an oscilloscope is also installed inside the housing. The oscilloscope is fixedly installed inside the housing and is electrically connected to the controller.

[0027] By adopting this technical solution, the oscilloscope can directly test the current and voltage of the sensor connected to the data interface and display the test signal on the screen. When testing current and voltage, the oscilloscope can intuitively display the test situation in the form of waves. The staff can judge whether the current and voltage of the sensor are normal based on the waveform, and at the same time, they can judge the performance of the sensor based on the waveform and determine whether the sensor needs to be replaced.

[0028] In summary, this utility model has at least one of the following beneficial technical effects:

[0029] 1. During the inspection process, by connecting the data interface and the sensor's data interface, and inserting the sensor probe into the detection mechanism, the environment in which the sensor probe is located can be changed in real time. Combined with the sensor's parameters, the working status of the sensor can be judged, thereby realizing the detection of the sensor's working status and performance, and effectively improving the reliability of sensor detection.

[0030] 2. The heating, humidifying, and blowing components in the testing mechanism can quickly change the environmental parameters inside the testing chamber, such as temperature, humidity, and airflow rate. This allows the device to simulate the working state of sensors under different environmental conditions, thereby effectively testing temperature, humidity, and flow sensors and ensuring the reliability and accuracy of the sensors in various working environments.

[0031] 3. By setting up a switching mechanism, the moving parts, the protruding parts on the switching mechanism, and the first and second driving parts electrically connected to the controller, the automatic switching and detection of multiple reference sensors can be realized without manual intervention. The device can automatically select the appropriate reference sensor according to the type of sensor to be detected and perform detection, thereby improving the automation level and work efficiency of the inspection device.

[0032] 4. After the reference sensor is used, the elastic element will automatically retract the reference sensor, reducing the probability of sensor damage caused by human error and extending the service life of the reference sensor. Attached Figure Description

[0042] Reference Figure 2An oscilloscope 8 is also installed inside the housing 1. The oscilloscope 8 is connected to the controller 4. After the controller 4 recognizes the signal of the sensor under test, the voltage and current of the sensor under test can be detected by the oscilloscope 8, and the waveform of the sensor under test can be observed on the display screen 2. The characteristics of the waveform, such as stability, response time and signal strength, can be analyzed to comprehensively evaluate the performance and reliability of the sensor.

[0043] Reference Figures 3 to 4 The detection mechanism 6 includes a detection chamber 601, a generator 602, multiple reference sensors 604, and a data interface 603. The data interface 603 uses a USB or RJ45 interface for data transmission and is fixedly mounted on the side wall of the housing 1. The data interface 603 and the controller 4 are connected via wires. The multiple reference sensors 604 are a temperature reference sensor 604, a humidity reference sensor 604, and a flow rate reference sensor 604, and these multiple reference sensors 604 are slidably mounted within the detection chamber 601. By setting multiple different types of reference sensors 604 for detection, such as temperature sensors, humidity sensors, and flow rate sensors, the applicability of the inspection device for detecting different sensors is improved. By comparing the parameters of the sensor under test with the parameters of the reference sensors 604, it is possible to more accurately determine whether the sensor under test is in normal working condition.

[0044] Reference Figures 2 to 3The testing chamber 601 includes a chamber body, a water-absorbing component 6012, and a sealing cover 605. The chamber body of the testing chamber 601 has a square structure with five sealed sides and one open side. The housing 1 is designed with a mounting port for fixing the testing chamber 601. The chamber body of the testing chamber 601 is fixedly installed on the housing 1, with the opening of the chamber body facing away from the housing 1. A through-hole 6011 is provided on the end face of the chamber body opposite to the opening. The through-hole 6011 is circular. The water-absorbing component 6012 is annular and covers the through-hole 6011. The water-absorbing component 6012 is made of cotton cloth and absorbs... The outer ring of the water element 6012 fits onto the inner ring of the protrusion hole 6011. The inner ring of the water element 6012 has the same diameter as the outer ring of the reference sensor 604. A sliding groove is provided on one end face of the mounting port on the housing 1. A slider is provided on the sealing cover 605. By cooperating with the sliding groove and the slider, the sealing cover 605 is slidably mounted on the housing 1.

When in use, the sealing cover 605 can be opened directly to insert the sensor to be tested into the detection chamber 601, making it easy to place and remove the sensor. The water-absorbing component 6012 has good water absorption. When the reference sensor 604 passes through the protrusion hole 6011, the water-absorbing component 6012 can wipe the outer wall of the reference sensor 604, reducing the impact of stains on the reference sensor 604 on the data of the next test. The sealing cover 605 can protect the detection chamber 601, reduce the entry of stains, and extend the service life of the device.

[0045] Reference Figures 3 to 4 The generator 602 includes a heating element 6022, a humidifying element 6023, a blowing element 6024, and a connecting element 6021. The connecting element 6021 is a metal frame fixedly installed on the side wall inside the detection chamber 601. The heating element 6022 is an infrared heating tube, which is fixedly installed on the connecting element 6021 and electrically connected to the controller 4. The humidifying element 6023 is an ultrasonic atomizing plate with a small water tank. Both the ultrasonic atomizing plate and the small water tank are fixedly installed on the connecting element 6021, and the ultrasonic atomizing plate is electrically connected to the controller 4.

[0046] Reference Figures 4 to 5The housing 1 also houses a switching mechanism 7, which includes a movable part 701, an extension part 702, an elastic part 703, and a support part 707. The movable part 701 is a ring-shaped structure rotatably mounted on the housing 1. The housing 1 is provided with a mounting shaft, and the ring-shaped structure is sleeved on the mounting shaft. The movable part 701 has multiple cylindrical mounting holes 7011 arranged circumferentially. The axial direction of the mounting holes 7011 is parallel to the axial direction of the movable part 701. Each mounting hole 7011 also has a corresponding first limiting part with a diameter smaller than that of the mounting hole 7011. Each mounting hole 7011 also has a corresponding extension part 702, which includes a second limiting part and a push-out part. The second limiting part passes through the first limiting part, and the push-out part passes through the mounting hole 7011. The push-out part is located at the end of the second limiting part away from the first limiting part. The diameter of the push-out part is larger than the inner diameter of the first limiting part. The elastic element 703 is a tension spring, which is sleeved on the second limiting part and its two ends are respectively fixedly connected between the first limiting part and the push-out part. The support element 707 is a buffer pad made of rubber. Multiple support elements 707 are evenly arranged on the inner wall of the mounting hole 7011. Multiple reference sensors 604 are respectively installed on the push-out part of the protrusion 702. When the protrusion 702 extends, it can push the reference sensor 604 out of the mounting hole 7011 and push the reference sensor 604 through the protrusion hole 6011 of the detection chamber 601 out of the detection chamber 601. When the protrusion 702 retracts, it can drive the reference sensor 604 back into the mounting hole 7011. When multiple different types of reference sensors 604 are installed in the detection chamber 601, the corresponding reference sensor 604 can be switched to the detection chamber 601 by adjusting the movable part 701 according to the type of sensor to be detected. The reference sensors 604 that are not used can be moved out of the detection chamber 601, saving space in the detection chamber 601 and reducing the probability of damage caused by collision between the sensors and the reference sensors 604. Furthermore, by setting the elastic part 703, the reference sensor 604 can be automatically retracted after use, reducing the possibility of forgetting to retract the sensor.

[0047] Reference Figures 4 to 5The switching mechanism 7 further includes a first driving member 704, a second driving member 705, and a transmission member 706. Both the first driving member 704 and the second driving member 705 are motors, and both motors are connected to the controller 4 via wires. The first driving member 704 is fixedly mounted on the mounting shaft of the movable member 701, and the movable member 701 is provided with a gear for transmission connection with the first driving member 704. The first driving member 704 drives the movable member 701 to rotate through gear meshing. The second driving member 705 is mounted on the side of the movable member 701 where the first limiting part is located. The transmission member 706 is an electric push rod, and the extension direction of the electric push rod is perpendicular to that of the movable member 701. With the same axial direction, the electric push rod is driven by the second drive member 705, which extends the protruding end of the electric push rod along the axial direction of the movable member 701. The installation positions of the second drive member 705 and the electric push rod correspond to the positions of the mounting holes 7011. When the second drive member 705 drives the electric push rod to extend, it can press against the end of the protruding member 702 in the mounting hole 7011 and push the protruding member 702 out along the direction of the mounting hole 7011, so that the reference sensor 604 passes through the protrusion hole 6011 of the chamber and enters the detection chamber 601. When the second drive member 705 drives the electric push rod to retract, the protruding member 702, under the action of the elastic member, retracts into the mounting hole 7011 together with the reference sensor 604. Through the electronic control operation of the first drive member 704 and the second drive member 705, the switching of the reference sensor 604 can be completed automatically without manual intervention. At the same time, the controller 4 controls the rotation of the movable member 701 and the sliding of the transmission member 706, which can quickly switch the corresponding reference sensor 604 according to different types of sensors to be detected, thereby improving detection efficiency.

[0048] The implementation principle of an industrial IoT sensor inspection device according to this embodiment is as follows: Open the sealing cover 605 of the device, insert the sensor to be tested into the detection chamber 601, connect the data cable of the sensor to be tested to the data interface 603 of the device, and adjust the controller 4 via the control button 3 to switch the reference sensor 604 to the same detection mode as the sensor to be tested. The controller 4 activates the generator 602, changing the internal environment of the detection chamber 601 through the heating element 6022, humidifying element 6023, and blowing element 6024, so that the sensor probe is in a changing environment. The controller 4 simultaneously receives data from both the sensor to be tested and the reference sensor 604, and displays the sensor status parameters in real time on the display screen 2. Operators can determine whether the sensor is in normal working condition based on the changes in the sensor status parameters on the display screen 2. After the test is completed, disconnect the sensor connection and remove the sensor from the detection chamber 601. Remove the sensor from 01 and close the sealing cover 605. When switching the reference sensor 604, the first driving member 704 drives the movable member 701 to rotate on the housing 1. The movable member 701 will rotate until the required reference sensor 604 is aligned with the extension hole 6011 of the detection chamber 601. The second driving member 705 drives the transmission member 706 (electric push rod) to extend along the axial direction of the movable member 701. When the electric push rod extends, it presses against the end of the protrusion 702 in the mounting hole 7011 of the movable member 701, pushing the protrusion 702 out along the direction of the mounting hole 7011. The protrusion 702 pushes the reference sensor 604 through the extension hole 6011 of the detection chamber 601, so that it enters the detection chamber 601. When it is necessary to retract the reference sensor 604: the second driving member 705 drives the electric push rod to retract. Under the action of the elastic member 703, the protrusion 702 drives the reference sensor 604 to retract into the mounting hole 7011.

[0049] In summary, by connecting the sensor to the data interface 603 and placing the probe in the detection chamber 601, the device can change the environmental conditions inside the detection chamber 601 in real time and monitor sensor parameters, thereby providing a more comprehensive evaluation of the sensor's working status and performance. The heating element 6022, humidifying element 6023, and blowing element 6024 in the detection mechanism 6 can quickly adjust the temperature, humidity, and airflow inside the detection chamber 601, simulating various working environments and suitable for detecting various types of sensors. The device is equipped with a switching mechanism 7, which can automatically select and switch the appropriate reference sensor 604 according to the type of sensor to be detected, improving detection efficiency. After use, the elastic element 703 automatically retracts the reference sensor 604, reducing the risk of damage caused by human error and extending the service life of the reference sensor 604. These features enable the industrial IoT sensor inspection device in this embodiment to efficiently and accurately detect the working status of various sensors, improving the reliability and automation of the inspection work.
