[0002] Portable modular measurement equipment based on PXI (Peripheral Component Interconnect extensions for Instrumentation) or PXIe (PXI Express) bus has been widely used in aerospace and defense, semiconductor manufacturing, industrial automation testing and other fields.

[0003] For example, modular measurement equipment based on the PXIe bus is commonly found on the market. This vertical PXIe architecture results in an excessive number of external interfaces, making them difficult to identify, and the enclosure is bulky, making it difficult to carry.

[0004] In this regard, the existing technology provides a horizontal plug-in PXIe architecture, which can make the housing design relatively thin, easy to carry and transport, and conducive to field testing. Specifically, the housing of this horizontal plug-in PXIe architecture needs to accommodate hardware such as the PXIe system controller board and various functional boards. At the same time, a heat dissipation system needs to be configured in the housing to ensure the heat dissipation requirements of the PXIe system controller board and various functional boards. Among them, the PXIe system controller board and functional boards are placed in partitions in the housing, and heat dissipation ducts are arranged in the housing for the PXIe system controller board and functional boards respectively, resulting in a relatively bloated internal space of the housing, which is not conducive to the reduction of the overall volume of the machine, and thus affects the portability of the entire machine.

[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] In the existing horizontally plugged-in PXIe architecture, the PXIe system controller board and functional boards are placed in partitions within the chassis, and separate cooling ducts are arranged for the PXIe system controller board and functional boards within the chassis. This results in a relatively bloated internal space of the chassis, which is not conducive to streamlining the overall size of the machine and thus affects the portability of the entire machine.

[0042] To this end, this embodiment provides a portable modular measuring device to solve the above problems.

[0043] For details, please refer to Figures 1 to 3 The portable modular measuring device includes a portable modular measuring device platform. The portable modular measuring device platform includes a housing 1, a bracket 2 and a cooling fan 51. The housing 1 includes a chassis body and a front panel 13 and a rear panel 14 respectively arranged at the front and rear ends of the chassis body. The chassis body, the front panel 13 and the rear panel 14 are arranged to form a receiving cavity. The left and right ends of the chassis body are respectively provided with a first ventilation hole 1111 and a second ventilation hole 1121. The rear panel 14 is provided with an opening 15. The first ventilation hole 1111, the second ventilation hole 1121 and the opening 15 are all connected to the receiving cavity. The bracket 2 is located in the receiving cavity. The bracket 2 includes an installation area 21 and a card insertion area 22 arranged in sequence along the left and right directions. The installation area 21 is provided with an installation space, and the card insertion area 22 is provided with multiple slots. The slots extend in the front-to-back direction, and the slot entrances are opposite to the opening 15. The dimensions of each slot in the front-to-back direction, the left-to-right direction, and the vertical direction decrease in sequence. The bracket 2 is provided with air duct holes along the left-to-right direction. Both the installation space and the slots are connected to the air duct holes. Both ends of the air duct holes are connected to the accommodating cavity, and the two ends of the air duct holes are respectively opposite to the first ventilation hole 1111 and the second ventilation hole 1121; the cooling fan 51 is provided in the installation space. In this embodiment, the left-to-right direction is as follows Figure 1 The direction indicated by the arrow cd, the front and back directions are as follows Figure 1 The direction indicated by the arrow ef, the vertical direction is as follows Figure 1 The direction indicated by arrows ab.

[0044] The portable modular measuring equipment platform provided in this embodiment has a housing 1 whose internal space is divided into an installation area 21 and a card insertion area 22 by a bracket 2. The slot in the card insertion area 22 is used to insert boards, and when the boards are inserted into the slots, they can be inserted into the slots through the opening 15 at the rear end of the housing 1, which is convenient for operation. The air duct runs through the bracket 2 in the left and right directions, and the extension direction of the air duct is perpendicular to the extension direction of the slot. Driven by the cooling fan 51, the air flowing through the air duct can take away the heat emitted by the boards in time, ensuring the heat dissipation effect of the boards. The internal space of the bracket 2 is used to construct the air duct for heat dissipation, without occupying additional space inside the accommodating cavity, which is conducive to improving the utilization efficiency of the internal space of the housing 1, thereby reducing the volume of the housing 1 and improving the portability of the entire machine. Since the size of the slot in the vertical direction is the smallest, the board is in a horizontal state after being inserted into the slot, which can effectively reduce the height of the housing 1 and further improve the portability of the entire machine.

[0045] It should be noted that the housing 1 in this embodiment is directly attached to the exterior of the bracket 2. The bracket 2 adopts a frame structure and is used to support the housing 1 on the one hand and various components mounted on the bracket 2 on the other hand, such as the cooling fan 51 and the boards, which can effectively reduce the weight of the entire device and further improve the portability of the entire device.

[0046] Alternatively, see Figure 3 The portable modular measuring device also includes a card, with the card inserted into at least some of the slots. In this embodiment, the card is generally rectangular, with the height of the card being the smallest among its length, height, and width. This means that the card is positioned horizontally after being inserted into the slot. Furthermore, the width of the card is oriented in the left-right direction, while the length of the card is oriented in the front-back direction.

[0047] Optionally, in this embodiment, the height dimension of the casing 1, the width dimension of the casing 1 and the length dimension of the casing 1 are reduced successively, the height direction of the casing 1 is along the vertical direction, the width direction of the casing 1 is along the front-to-back direction, and the length direction of the casing 1 is along the left-to-right direction. The casing 1 is flat in style and is easy to carry.

[0048] Optionally, each card is inserted into opening 15, with an external interface at one end and a backplane connector at the other end. Specifically, when the card is inserted into the slot, one end of the backplane connector passes through opening 15 from back to front and is inserted into the slot, where it is plugged into the backplane 7 of the portable modular measurement device platform. The external interface end of the card is located outside the housing 1, facilitating plugging with external devices for data transmission. This helps reduce the internal space occupied by the housing; furthermore, providing opening 15 in the housing 1 also helps reduce the weight of the housing 1.

[0049] Alternatively, please continue to refer to Figure 3 The card insertion area 22 is provided with multiple slot groups, which are arranged in a sequential horizontal direction. Each slot group includes multiple slots arranged in a sequential vertical direction. This arrangement forms a rectangular array of slots in both the horizontal and vertical directions, allowing the slots to simultaneously accommodate multiple boards. In other embodiments, the slots in the card insertion area 22 are arranged in a sequential vertical direction. This arrangement is equivalent to providing only a single column of slots.

[0050] In this embodiment, the number of slots included in the slot group can be set according to actual needs. The number of slots included in the slot group directly determines the height of the housing 1, because the height of the housing 1 is equal to the sum of the total height of the multiple slots included in the slot group, the vertical wall thickness of the housing 1, and the vertical wall thickness of the bracket 2. Considering that the vertical wall thickness of the housing 1 and the vertical wall thickness of the bracket 2 are both relatively small, the vertical height of the housing 1 is approximately equal to the total height of the multiple slots in the slot group. By adjusting the number of slots included in each slot group, the height of the housing 1 can be adjusted.

[0051] Optionally, the vertical height of the housing 1 is approximately equal to D, where D = n*0.5U. Here, n is a positive integer. The height of each slot is 0.5U, where U is a unit of length, typically referring to a "Rack Unit" or "RU." In computer hardware, telecommunications equipment, and other rack-mounted devices, 1U is used to represent the height of equipment in a rack or cabinet. 1U is equal to a height of 1.75 inches (44.45 mm). Specifically, this embodiment exemplifies the following solution: the card insertion area 22 is provided with two slot groups, which are arranged in sequence in the left-right direction, and each slot group includes three slots arranged in sequence in the vertical direction. Therefore, in this embodiment, the height of the housing 1 is approximately 1.5U. In other embodiments, each slot group may include two, four, five, or other numbers of slots arranged in sequence in the vertical direction, as needed, thereby making the height of the housing 1 approximately 1U, 2U, 2.5U, or other heights.

[0052] Optionally, the board can be a system controller board 3 or a function board 4. The system controller board 3 can be a PXI system controller board or a PXIe system controller board. The height of the function board 4 and the height of the system controller board 3 are typically 0.5U or 1U, and the slot height is 0.5U. For a 0.5U-high function board 4 or system controller board 3, one slot is required, while for a 1U-high function board 4 or system controller board 3, two slots are required. In other words, each slot can accommodate a 0.5U-high function board 4 or system controller board 3 individually; two vertically adjacent slots can collectively accommodate a 1U-high function board 4 and system controller board 3. Therefore, in this embodiment, the three slots in each slot group can simultaneously accommodate three 0.5U-high function boards 4 or system controller boards 3, or one 0.5U-high function board 4 or system controller board 3 and one 1U-high function board 4 or system controller board 3.

[0053] For example, please refer to Figure 3 In this embodiment, the portable modular measuring device includes multiple boards, including a system controller board 3 and multiple function boards 4. The system controller board 3 is 1U tall and occupies two slots. Each function board 4 is 0.5U tall and occupies one slot. In other embodiments, the portable modular measuring device includes one board; alternatively, the portable modular measuring device includes multiple boards, all of which are function boards 4.

[0054] Optionally, in this embodiment, each slot is plugged into a card, and one end of each of the multiple cards extends through opening 15 and out of the accommodating cavity, with the opening 15 being closed by the multiple cards. This arrangement prevents air from entering the accommodating cavity through opening 15 when the cooling fan 51 is operating, thereby affecting the cooling effect on the cards. It should be noted that each slot can be plugged into a card with a height of 0.5U, or a card with a height of 1U can be plugged into two slots simultaneously.

[0055] As an alternative, the portable modular measuring device further includes a windshield 6. The multiple slots include functional slots and expansion slots, each of which is plugged with a board. The number of windshields 6 is equal to the number of expansion slots, and they correspond one-to-one. Each windshield 6 is positioned at an opening 15, facing the corresponding expansion slot. The opening 15 is enclosed by the board and windshield 6. The expansion slots are used to allow users to plug in required functional boards 4 as needed. The openings 15 corresponding to the expansion slots are shielded by windshields 6, allowing the openings 15 to be enclosed by the system controller board 3, the functional boards 4, and the windshields 6, thus ensuring effective heat dissipation.

[0056] In this embodiment, the cooling fan 51 is an exhaust fan. The cooling fan 51 is located adjacent to the second plate 112 and away from the first plate 111. Driven by the cooling fan 51, outside air enters the interior of the housing 1 through the first ventilation holes 1111 and is exhausted through the air duct from the second ventilation holes 1121. In other embodiments, the cooling fan can also be configured as an exhaust fan as needed; alternatively, the bracket 2 can be separated into two mounting areas 21 and a card insertion area 22. The two mounting areas 21 are located at the left and right ends of the card insertion area 22, and the two card insertion areas 22 are used to accommodate the exhaust fan and the exhaust fan, respectively. The exhaust fan and the exhaust fan cooperate to further enhance the heat dissipation effect.

[0057] Optionally, the top and bottom ends of the bracket 2 are provided with a plurality of air inlets connected to the air duct. After the outside air enters the accommodating cavity through the first ventilation hole 1111, it can enter the air duct through the entrance at one end of the air duct close to the first ventilation hole 1111 and each air inlet, thereby also dissipating heat for other components located outside the slot.

[0058] In addition, this embodiment does not limit the number of cooling fans 51. In this embodiment, an exemplary solution is provided in which the number of cooling fans 51 is set to three, and the three cooling fans 51 are integrated into a fan mounting bracket 52, which is fixed to the bracket 2 and located in the installation space.

[0059] Alternatively, please continue to refer to Figures 1 to 3The chassis body includes a first cover plate 11 and a second cover plate 12, a front panel 13, and a rear panel 14. The front panel 13 is connected to the front end of the first cover plate 11 and the front end of the second cover plate 12, respectively, and the rear panel 14 is connected to the rear end of the first cover plate 11 and the rear end of the second cover plate 12, respectively. The first cover plate 11 includes a first plate 111 and a second plate 112 that are parallel and spaced apart in the left-right direction, and a third plate 113 that is connected between the top of the first plate 111 and the top of the second plate 112. A first ventilation hole 1211 is provided in the first plate 111, and a second ventilation hole 1121 is provided in the second plate 112. The second cover plate 12 and the third plate 113 are parallel and spaced apart in the vertical direction, and the second cover plate 12 is connected between the bottom end of the first plate 111 and the bottom end of the second plate 112. The opening 15 is adjacent to the first plate 111 and away from the second plate 112. In this embodiment, the housing 1 is assembled from a first cover plate 11, a second cover plate 12, a front panel 13, and a rear panel 14. This facilitates assembly and disassembly, facilitating maintenance of other components within the housing 1. The bracket 2 can be fixed to the second cover plate 12 of the housing 1 using screws or other fasteners.

[0060] Specifically, in this embodiment, the chassis body is in the form of a rectangular parallelepiped, and the first cover plate 11 is U-shaped. The first cover plate 11 is located above the second cover plate 12. When viewed from the back to the front, the opening 15 is adjacent to the first plate 111, and the opening 15 is spaced apart from the second plate 112. When viewed from the front to the back, the first plate 111 is located to the left of the third plate 113 and the second cover plate 12, and the second plate 112 is located to the right of the third plate 113 and the second cover plate 12. In other embodiments, the first cover plate 11 can also be located below the second cover plate 12 as needed.

[0061] Preferably, please refer to Figure 3 The lower surface of the second cover plate 12 is further provided with a plurality of feet 121 for supporting the entire device during use. The number of feet 121 can be set according to actual needs. In this embodiment, a solution with four feet 121 is exemplified, and the four feet 121 are arranged in a rectangular shape.

[0062] Alternatively, see Figure 1 and Figure 3 The portable modular measuring device platform further includes a switch button 131 disposed on the front panel 13. Optionally, the portable modular measuring device platform further includes a display screen 132 disposed on the front panel 13. By arranging the switch button 131 and the display screen 132 on the front panel 13, it is convenient to turn the device on and off using the switch button 131, and to monitor the entire device using the display screen 132, making the entire device appear simple and beautiful.

[0063] Alternatively, see Figure 2 and Figure 3, the portable modular measuring device platform also includes a DC power input port 141 provided on the rear panel 14. The DC power input port 141 is used to connect to an external power supply. Further optionally, the portable modular measuring device platform also includes a data input / output interface 142 provided on the rear panel 14, and the data input / output interface 142 is used for data transmission between the entire machine and other devices. In this embodiment, the data input / output interface 142 is preferably an SMA data input / output interface. Exemplarily, the number of data input / output interfaces 142 is set to 5. In other embodiments, the number and type of data input / output interfaces 142 can also be set as needed. Further optionally, the portable modular measuring device platform also includes a grounding column 143 provided on the rear panel 14. The grounding column 143 is used to connect the grounding wire to ensure the electrical safety of the entire machine.

[0064] Alternatively, see Figure 3 The portable modular measurement device platform also includes a backplate 7 disposed within the accommodating cavity. Backplate 7 faces the card insertion area 22 and is located between the bracket 2 and the rear panel 14. Specifically, from the front to the back, the bracket 2 is located in front of the backplate 7, and the backplate 7 is mounted to the bracket 2. By arranging the bracket 2 and the backplate 7 in a sequential manner, the space within the accommodating cavity can be effectively utilized. The backplate 7 is used to plug and mate with the rear end of the card.

[0065] Alternatively, please continue to refer to Figure 3 The portable modular measuring device platform also includes a power board 8 disposed on the back panel 7. Along the front-to-back direction, the DC power input port 141 is located on the rear side of the bracket 2, and the power board 8 is located on the front side of the bracket. The power board 8 is electrically connected to the DC power input port 141. With this arrangement, power can be supplied to the power board 8 via the DC power input port 141, and integrating the power board 8 into the back panel 7 can effectively improve assembly efficiency. Preferably, the DC power board 8 and the DC power input port 141 are directly opposite each other, which allows for a relatively short routing path for the connecting cable between the power board 8 and the DC power input port 141.

[0066] Alternatively, please continue to refer to Figure 3 The chassis body is equipped with multiple mounting interfaces 1122. By integrating these interfaces 1122 into the chassis 1, the portable modular measuring device can be used not only independently but also mounted on a cabinet, expanding its applicability. Specifically, both the first plate 111 and the second plate 112 are provided with mounting interfaces 1122.

[0067] Optionally, the portable modular measuring device platform also includes a plurality of temperature sensors arranged in the accommodating cavity. By setting the temperature sensor to detect the temperature in the accommodating cavity, the rotation speed of the cooling fan 51 is adjusted to ensure that the temperature of each electronic component in the accommodating cavity is normal. Specifically, in this embodiment, at least two temperature sensors are provided in the accommodating cavity, and the rotation speed of the cooling fan 51 is adjustable. At least two temperature sensors are distributed near the system controller board 3, the function board 4 and the backplane 7. The temperature of the accommodating cavity is detected by the temperature sensor, and the detected temperature is sent to the controller. The controller compares the acquired temperature with the preset temperature range. When the acquired temperature exceeds the temperature range, the controller controls the cooling fan 51 to run at a high speed; when the acquired temperature does not exceed the temperature range, the controller controls the cooling fan 51 to run at a low speed so that the temperature in the accommodating cavity can be maintained within the set temperature range.

[0068] It should be noted that, in this embodiment, when the core chip of the system controller board 3 or the function board 4 has a relatively large heat consumption, in order to ensure the normal operation of the system controller board 3 or the function board 4, a cooling plate 41 may be integrated on the system controller board 3 or the function board 4, and a cooling fan 42 may be integrated on the cooling plate 41. Figure 4 Taking the enhancement of heat dissipation for the functional board 4 as an example, a cooling plate 41 is provided on the functional board 4, and a cooling fan 42 is provided on the cooling plate 41. Heat generated by the functional board 4 is transferred to the cooling plate 41, and the cooling fan 42 promotes heat exchange between the air and the cooling plate 41, thereby improving the heat dissipation effect on the functional board 4 and ensuring the normal operation of the functional board 4. The cooling fan 42 can be a micro-turbo fan.
