[0002] Industrial computers, or industrial control computers, are computer devices used in industrial environments, adapted to industrial requirements, and used to complete data collection and control of industrial processes. Industrial computers directly control industrial production processes, so they are required to be able to operate continuously and stably in industrial environments, that is, they are required to be able to work continuously and reliably for a long time in harsh environments such as dust, high temperature, vibration, and electromagnetic interference. In order to test the adaptability of industrial computers in harsh environments, it is usually necessary to use a test platform to simulate various industrial environments.

[0003] However, the current IPC testing platform is not adaptable enough to different models of IPCs and has poor versatility. In addition, when testing a dust environment, the current testing method can only blow dust in from one direction, and the simulation effect of the dust environment is not perfect. There are defects in the simulation effect of the actual dust environment in which the IPC is located. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-2 As shown, an industrial computer test platform comprises a table top 1 arranged horizontally; top columns 2 are respectively fixed vertically at the four corners of the lower end of the table top 1; pillars 3 are coaxially arranged below the top column 2; the pillars 3 and the top column 2 are connected by a buffer spring 4; a mounting support 5 is fixed on the lower side of the table top 1; the mounting support 5 is used to fix the vibration equipment; an adjustable positioning device for mounting the industrial computer and a sealing device for enclosing and surrounding the industrial computer are arranged on the upper side of the table top 1;

[0022] like Figure 3 As shown, the adjustable positioning device comprises through slots 6 respectively opened on the front and rear sides of the table top 1 along the left and right directions; the lower ends of the through slots 6 are respectively closed by buckle covers 7 fixed to the lower side of the table top 1; the buckle covers 7 are used for sealing to prevent dust from leaking out through the through slots 6 during dust simulation; two support blocks 8 are slidably connected in each through slot 6; the upper ends of the support blocks 8 are provided with bearing bars 9 along the front and rear directions; the bearing bars 9 are provided with a plurality of positioning screw holes 10; the lower ends of the bearing bars 9 are provided with dovetail grooves 11 along the front and rear directions; the dovetail grooves 11 are slidably connected to the upper ends of the support blocks 8;

[0023] like Figure 4As shown, the sealing device includes a sealing cover 12 arranged on the table 1; the through grooves 6 are all located inside the sealing cover 12; the outer side of the lower end of the sealing cover 12 is connected to the table 1 by a locking bolt 13; the sealing cover 12 is a truncated cone structure; two retaining rings 14 are respectively sleeved and fixed on the outside of the sealing cover 12, one above and one below; a sleeve ring 15 is correspondingly provided between the two retaining rings 14; the sleeve ring 15 is rotatably sleeved with the outer wall of the sealing cover 12; a plurality of open ports 16 are opened on the sealing cover 12 in the circumferential direction; the open ports 16 are all sealed and blocked by the sleeve rings 15; a guide port 17 for connecting with an external dust simulation device is connected on the sleeve ring 15; a sealing plug 18 is inserted on the guide port 17; the guide port 17 is connected to the inside of the sealing cover 12 through the open port 16.

[0024] Before simulating the working conditions of the industrial computer, it is necessary to first fix the industrial computer on the table 1. Traditional test platforms can often only adapt to industrial computers of a single model and size. In this technical solution, by sliding the support block 8 left and right along the through groove 6, and sliding the dovetail groove 11 on the bearing bar 9 forward and backward along the support block 8, combined with the setting of multiple positioning screw holes 10 on the bearing bar 9, the range of adaptation to the installation point of the industrial computer can be expanded, and it is suitable for the installation of various types of industrial computers, and has strong versatility. It should be noted that when the industrial computer is connected to the bearing bar 9, it is connected to the positioning screw hole 10 at the appropriate position on the bearing through the connecting bolt. At this time, in addition to connecting the bearing bar 9 to the industrial computer, the connecting bolt can pass through the positioning screw hole 10 and tighten against the table 1 to achieve the fixation between the bearing bar 9 and the table 1, that is, to achieve the stable positioning of the industrial computer.

[0025] When it is necessary to simulate a dust environment, cover the cover 12 outside the industrial computer and fix it on the table 1, then connect the guide port 17 to the external dust simulation equipment (pull out the sealing plug 18 first), and the dust can be blown into the cover 12 through the guide port 17 and the open port 16, so that the dust is distributed around the industrial computer, simulating the operation of the industrial computer in a dust environment. However, due to the unique structure of some industrial computers, in principle, it is determined that dust blown from certain directions will not affect the industrial computer. In order to more comprehensively simulate the tolerance to dust in other directions, in this technical solution, the ring 15 can be rotated to change the direction of the guide port 17, that is, the direction of the dust blowing in is changed, thereby improving the comprehensiveness of the simulation.

[0026] When it is necessary to simulate a vibration environment, the external vibration equipment is fixed on the mounting bracket 5, and the vibration can be transmitted to the industrial computer. At the same time, the setting of the buffer spring 4 makes the vibration effect more prominent and the vibration amplitude more obvious, thereby effectively simulating and highlighting the ability of the industrial computer to withstand vibration.

[0027] like Figure 2As shown, the pillar 3 and the top pillar 2 have the same diameter; a limiting screw sleeve 19 is threadedly sleeved on the pillar 3; when the lower end of the limiting screw sleeve 19 is sleeved on the upper part of the pillar 3, the upper end of the limiting screw sleeve 19 is threadedly connected to the lower part of the top pillar 2.

[0028] By limiting the screw sleeve 19, the support column 3 and the top column 2 can be relatively fixed to achieve stable support for the table top 1. When no vibration simulation is performed, the support positioning of the table top 1 is made more stable.

[0029] like Figure 4 As shown, at least two guide openings 17 are provided. By providing at least two guide openings 17, in addition to being convenient for blowing in dust, it is also convenient to connect a dust collecting device to extract the dust in time.

[0030] like Figure 1 As shown, a perspective window 20 is installed on the top of the cover 12. Through the perspective window 20, when the cover 12 is installed, the operation of the internal industrial computer can be clearly observed.
