Description

Technical Field

[0001] The embodiments of this disclosure generally relate to field testing of industrial equipment, and more particularly to portable industrial testing equipment for field testing of industrial equipment. Background Technology

[0002] In many industrial sectors, such as petroleum, chemical, power, and electrical equipment, there is a frequent need for condition monitoring and performance testing of industrial equipment (such as rotating equipment, pressure equipment, and switchgear). This allows for the acquisition of information about the industrial equipment on-site, enabling more effective analysis and diagnosis of its condition. These on-site tests typically utilize portable testing equipment. Taking rotating equipment as an example, vibration analyzers are usually used to collect vibration data, and performance reports are generated based on the specific conditions.

[0003] Traditional portable testing equipment suffers from the following technical problems: it supports a limited number of measurement channels, such as one or two, making it impossible to perform tests at multiple points using the same equipment. This makes it difficult to achieve simultaneous multi-point data acquisition during the same test, hindering the efficient reflection of the overall operating status of the equipment. The types of test data are limited, typically not supporting multi-type sensor testing, for example, only vibration monitoring. This results in complex wiring, proneness to errors, and low efficiency even if the equipment can be expanded. Consequently, it is impossible to achieve simultaneous acquisition of multiple types of data during the same test. In some cases, multi-type testing can be supported by adding expansion modules, such as attaching current clamps for current testing. However, this requires additional expansion modules, leading to complex wiring, proneness to errors, and low efficiency. Furthermore, the equipment provides only limited performance analysis and diagnostic capabilities; considering that the equipment primarily performs data acquisition functions or only provides simple data processing tools, it cannot provide complex diagnostic conclusions. There is a need for further improvements to traditional industrial testing equipment. Summary of the Invention

While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0028] The term "comprising" and its variations as used herein signify an open-ended inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Terms such as "upper", "lower", "front", and "rear", indicating placement or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the purpose of describing the principles of this disclosure, and are not intended to indicate or imply that the elements referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0029] This disclosure provides a portable industrial testing device with multiple preset channels, supporting various signal processing types. It enables centralized access and simultaneous multi-channel acquisition of multiple sensors, provides multi-parameter performance analysis, and significantly enhances on-site testing efficiency and reliability. The portable industrial testing device according to embodiments of this disclosure is described in detail below with reference to the accompanying drawings.

[0030] Figures 1-2 A schematic diagram of the structure of a portable industrial testing device 1 according to an embodiment of this disclosure is shown. Figures 1-2 As shown, the industrial testing equipment 1 includes a housing 10, an interface board 20, a data acquisition unit 30, and a processing unit 40 (see also reference). Figure 5 The enclosure 10 defines a cavity, and components such as the interface board 20, data acquisition unit 30, and processing unit 40 can be installed within it. The enclosure 10 provides protection for internal components and is portable. The enclosure may be constructed of rigid structures and / or materials to provide sufficient structural strength. The enclosure may include flat top and bottom walls, allowing for reliable protection. Figure 1 In the illustrated embodiment, the housing can be formed in the shape of a cuboid. It should be understood that... Figure 1 The embodiments shown are merely exemplary, and the housing can be formed into any other suitable shape.

[0031] The case 10 may include a handle 11. The handle 11 allows for convenient carrying of the case. In some embodiments, such as... Figure 1 As shown, the handle can be recessed. The handle 11 is positioned on the side wall of the housing 10 (in...). Figure 1 The front side wall (in the middle) may have an opening, and the handle 11 may be arranged flush with the side wall of the housing 10, providing space for gripping the handle 11. This layout can enhance the rigidity of the handle and has advantages such as aesthetics and better space efficiency.

[0032] In some embodiments, the housing 10 may include a top surface 12, a bottom surface opposite to the top surface 12, and four side surfaces located between the top and bottom surfaces. A handle 11 may be disposed on a first side surface 16 of the four side surfaces; an interface board 20 is disposed on a second side surface 18 opposite to the first side surface of the four side surfaces. This structural layout optimizes the overall structure of the testing equipment, achieving a balance between functions such as signal acquisition, cooling, and portability.

[0033] In some embodiments, the enclosure 10 can be formed as a closed enclosure. This enclosure prevents the user from opening the enclosure. This is beneficial for ensuring the protection of the internal structure of the enclosure, further improving the enclosure's dustproof and waterproof performance. Considering the use of the testing equipment in industrial settings, this closed enclosure structure is particularly advantageous. In some embodiments, such as... Figure 1 As shown, the housing 10 may include reinforcing members 17 at its corners to further enhance the structural performance of the housing 10.

[0034] Interface board 20 is configured to carry multiple sensor channels. Interface board 20 can be formed as a board and can be integrated into an outer wall of housing 10. Figure 2 In the illustrated embodiment, the interface board 20 is integrated into a back sidewall (i.e., the second side surface 18) opposite to the front sidewall. The interface board 20 is provided with a plurality of input interfaces 22 adapted for connection to multiple sensors, respectively. According to this disclosure, the multiple sensors include at least two types of sensors, such as vibration sensors and process sensors. Therefore, data acquisition from multiple types of sensors can be achieved simultaneously without requiring expansion of the test equipment.

[0035] In some embodiments, the sensor may include multiple types of sensors, such as vibration sensors and process sensors. This allows the testing equipment to simultaneously acquire multiple types of data. In some embodiments, the sensor includes at least two of the following: vibration sensors, pressure sensors, temperature sensors, flow sensors, level sensors, position sensors, pH sensors, concentration sensors, etc. It should be understood that the above sensor types are merely exemplary, and the sensor may include any other type of sensor.

[0036] In some embodiments, the multiple input interfaces 22 are implemented as standardized sensor connectors. These input interfaces may be arranged, for example, in multiple rows. The number of input interfaces may be, for example, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or more. In some embodiments, the multiple input interfaces 22 are integrated and mounted on the surface of the enclosure, such that none of the interfaces protrude from the end face of the enclosure, which is beneficial for improving the overall protection of the equipment and the safety of on-site operation.

[0037] exist Figure 2 In the illustrated embodiment, the interface board 20 has 12 input interfaces. In some embodiments, the appropriate number of sensor channels can be selected, particularly considering different application scenarios. In some embodiments, multiple input interfaces can be grouped; for example, some interfaces can only be used to test a certain type of sensor signal, while other interfaces can be shared for different sensor types. This can further simplify the complexity of downstream signal processing and reduce the hardware and / or software costs of the test equipment. Taking vibration testing applications as an example, when testing industrial equipment in the field, it may be necessary to frequently use interfaces for, for example, multiple vibration sensors, while only one sensor such as a temperature sensor is needed. In this case, some input interfaces of the multiple sensor interfaces can be set to only connect to vibration sensors, while other interfaces can connect to both vibration sensors and temperature sensors.

[0038] In some embodiments, such as Figure 2 As shown, the interface board 20 may further include an output interface or an input-output interface 24. The output interface or input-output interface 24 may include one or more of the following interfaces integrated in the interface board 20: a USB port, an HDMI port, a network port, etc. These ports allow the test equipment to be further connected to other external devices to output analysis results and / or sensor data for further processing and / or analysis, for example. In some embodiments, the processing unit 40 establishes a connection with an external display terminal, tablet, or laptop computer, for example, via a wired or wireless network, to achieve real-time display and interactive operation of test results.

[0039] In some embodiments, such as Figure 2 As shown, the housing 10 may also include a cover 15 that is detachably mounted to cover the interface board 20. The cover 15 provides protection for the input interface 22 on the interface board, preventing water or dust from entering the input interface 22 and affecting its performance. When the industrial testing equipment is in use, the cover 15 is removed to expose the interface board 20; when the industrial testing equipment is not in use, the cover 15 covers the interface board 20.

[0040] The data acquisition unit 30 is configured to communicatively connect to a plurality of input interfaces 22 on the interface board 20 to read sensor signals from the respective input interfaces 22 and convert the sensor signals into converted signals suitable for processing by the processing unit 40. In some embodiments, the data acquisition unit 30 may be arranged inside the housing 10, and the data acquisition unit may identify and process the sensor signals to generate signals suitable for processing by the downstream processing unit 40.

[0041] In some embodiments, reference is also made to Figure 4The data acquisition unit 30 may include a sensor type identification unit and a sensor signal processing unit. The sensor type identification unit is configured to determine the type of sensor. The sensor signal processing unit includes multiple signal processing modules corresponding to different sensor types. For example, the sensor type identification unit may identify the sensor type based on the sensor's communication protocol and the received sensor signal. After identifying the sensor type, a signal processing module corresponding to the identified type is selected from the multiple signal processing modules, and the corresponding signal processing module is used to convert the sensor signal into a converted signal suitable for processing by the processing unit 40.

[0042] Also refer to Figure 4 The processing unit 40 is a component of the testing equipment that performs sensor signal analysis and diagnosis. The processing unit 40 is implemented as a motherboard and installed within the cavity. It is communicatively connected to the data acquisition unit 30 to receive and process the converted signals to generate test reports. These test reports can be output, for example, via peripheral devices. In some embodiments, the processing unit 40 can be implemented as an industrial-grade motherboard processor, and may include a central processing unit, a network communication interface, a storage unit, etc. Multi-channel sensor signals acquired by the data acquisition unit 30 are transmitted to the processing unit 40 in real time, where they are processed, displayed, and / or stored.

[0043] Figure 3 A schematic diagram illustrating the circuit structure and peripheral devices of a portable industrial testing device according to an embodiment of the present disclosure is shown. Figure 3 As shown, the test device 1 may include an I / O interface 320, a data acquisition unit 330 connected to the I / O interface, and a processor 340 connected to the data acquisition unit 330. The I / O interface 320 can be implemented as a circuit board card, which can correspond to... Figure 1 and Figure 2 The interface board 20 is shown. The I / O interface 320 may include a substrate and I / O ports integrated on the substrate. Input ports in the I / O ports can, for example, be connected to multiple different types of sensors 372 to acquire signals from the sensors 372. Output ports in the I / O ports can, for example, be connected to peripheral devices 373 to output data, for example, from a processor 340, to the peripheral device. The data acquisition unit 330 can be implemented as a circuit board, corresponding to... Figure 1 and Figure 2The data acquisition unit 330 shown may include a substrate and a sensor type identification unit and a sensor signal processing unit integrated on the substrate. The sensor type identification unit may be implemented as, for example, a comparator, and the sensor signal processing unit may include, for example, a comparator, an analog-to-digital converter, etc. The processor 340 may be implemented as, for example, a circuit board (e.g., a motherboard), and may correspond to... Figure 1 and Figure 2 The processing unit 40 shown. The processor 340 can integrate units such as a CPU and memory, and can be configured to process various types of sensor signals, thereby providing powerful on-site analysis and diagnostic capabilities.

[0044] In some embodiments, such as Figure 3 As shown, the test equipment may also include a power module configured to power the test equipment. The power module includes an external power adapter 360. The external power adapter 360 can be connected to an external mains power supply 371. The external power adapter 360 can be integrated, for example, into the housing of the test equipment, and can be connected to a power source such as mains power. In this way, the user is spared the need to carry an external power adapter, further improving the portability of the test equipment. In some embodiments, such as Figure 3 As shown, in addition to the external power adapter 360, the test equipment may also include a battery 350. The battery 350 further enhances the test equipment's adaptability to different scenarios, ensuring normal operation even without an external power source. Figure 5 In the illustrated embodiment, the battery is indicated by reference numeral 44. In some embodiments, the battery 350 may be a rechargeable battery that can be charged via an external power adapter 360.

[0045] In some embodiments, such as Figure 1 As shown, when a battery is installed, the outer surface of the housing 10 may include a display 13 for showing the remaining battery power. This allows the user to easily observe the battery status. In some embodiments, the display 13 may be located, for example, on the front sidewall (i.e., the first side surface 16), adjacent to the handle 11, which facilitates user observation.

[0046] Figure 4 and Figure 5 A general schematic diagram of the main internal components of a portable industrial testing device according to an embodiment of the present disclosure is shown. In some embodiments, such as Figure 4 and Figure 5As shown, the data acquisition unit 30 and the processing unit 40 are arranged stacked on top of each other in the vertical direction. This helps to reduce the overall size of the testing equipment and make efficient use of the dimensions in the thickness direction. In addition, this is beneficial in terms of cooling, as airflow can be used to cool the data acquisition unit 30 and the processing unit 40 simultaneously.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, the data acquisition unit 30 and the processing unit 40 are each independently fixed inside the housing. The data acquisition unit 30 and the processing unit 40 can be independently fixed to, for example, the inner wall of the housing. The housing can be made of a rigid material such as metal. In some embodiments, the data acquisition unit 30 and / or the processing unit 40 are fixed to a bracket 50 disposed within the housing 10. The bracket 50 is disposed within the cavity and fixed to the housing 10 and extends in the vertical direction. The bracket 50 can be formed into a suitable shape and structure.

[0048] In some embodiments, the processing unit 40 is fixed to the bottom wall of the housing 10 or adjacent to the bottom wall of the support 50, and is configured to be stacked on top of the data acquisition unit 30 in the vertical direction and spaced apart from it by a gap. The gap between the processing unit 40 and the data acquisition unit 30 can, for example, be used to form an air duct.

[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the test equipment also includes a heat dissipation module. The enclosure 10 may include a first opening and a second opening disposed on opposite sides (e.g., side walls 14a, 14b) across the horizontal direction of the enclosure 10. The heat dissipation module includes a fan 52 arranged adjacent to at least one of the first and second openings. The first opening, the second opening, and the gap between the processing unit 40 and the data acquisition unit 30 define an airflow cooling path. By utilizing the side walls to form air ducts, and utilizing the front and rear side walls as interface plates and handles, the spatial layout of the enclosure is effectively utilized, achieving high performance for the test equipment.

[0050] Figure 6 The direction of airflow is also indicated by arrows. The stacked processing unit 40 and data acquisition unit 30 can guide the airflow. This direct current type can provide efficient cooling. Thus, during the operation of the test equipment, the forced convection formed by the fan 52 and the airflow cooling path ensure the stable operation of the internal components. In some embodiments, the processing unit 40 and / or data acquisition unit 30 are each separated from the corresponding wall of the enclosure by a distance. In this case, the gap between the respective wall and the processing unit 40 and / or data acquisition unit 30 can also be used as an air duct to further enhance the cooling capacity.

[0051] In some embodiments, such as Figure 4 and Figure 5 As shown, to ensure sufficient cooling capacity, multiple fans 52 can be provided, for example, at least two fans 52 can be provided on one side, and in particular, multiple fans can be provided on both side walls 14a and 14b. In some embodiments, the housing may also include a mesh 54 covering the first opening and the second opening respectively. The mesh can act as a filter to prevent dust, large particles, etc. from entering the equipment.

[0052] According to this disclosure, multi-type, multi-channel acquisition, processing and diagnostic capabilities are centralized on the same hardware platform. Through structural integration, multi-sensor, multi-channel synchronous acquisition is achieved, avoiding the size, wiring and reliability problems caused by external modules, improving on-site testing efficiency and reducing operational complexity.

[0053] Although the operations are described in a specific order, this should be understood as requiring that such operations be performed in the specific order shown or in sequential order, or requiring that all illustrated operations be performed to achieve the desired result. In certain environments, multitasking and parallel processing may be advantageous. Similarly, while several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of this disclosure. Certain features described in the context of individual embodiments may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented individually or in any suitable sub-combination in multiple implementations.
