Description

Technical Field

[0001] The present invention relates to the technical field of anti-interference testing and detection, and in particular to a device for detecting the anti-interference capability of equipment. Background Art

[0002] There are many digital monitoring products on the market. When an abnormality is detected, the monitor will generate an audible and visual alarm and upload the alarm data to the background or server. However, in the production or use of electronic products, the environment and electrical conditions are often complex, which may have a greater impact on the monitor itself, causing false alarms, resulting in a poor user experience or wasting manpower and material resources to investigate the cause. Therefore, it is necessary to use the device anti-interference ability detection device to perform interference testing on the monitor to ensure that the anti-interference ability is within the qualified range.

[0003] Among the existing published technical documents, the invention patent with Chinese patent publication number CN110487634A discloses a system and method for fine testing of core strain and resistivity under loading. This test detection technology is mainly connected to a computer through a data transmission line via a resistivity test module. It can be used for fine testing of strain and resistivity of core specimens. The test results have high visualization, strong anti-interference ability, stable output, and can obtain the changes in strain and resistivity of core specimens before and after destruction. The results can be used to calculate the mechanical parameters of core specimens and analyze the deformation and failure mechanism of rocks under load. However, this technology still has the following problems.

This makes it difficult to achieve accurate anti-interference testing according to different interval distances and different interval angles.

[0043] The use process of the device for detecting the anti-interference ability of the device of the present invention is as follows:

[0044] First, when the present invention performs contact rolling, by rotating the two screws 30, the screws 30 drive the threaded sleeve 31 to move downward under the action of the thread transmission force, the threaded sleeve 31 moves downward along the inner wall of the rotating frame 12, and the threaded sleeve 31 drives the bearing sleeve 32 to move downward, the bearing sleeve 32 drives the energized ball 33 to move downward, and the outer wall of the energized ball 33 contacts the upper position of the outer wall of the test end rod 16, so that the two energized balls 33 can contact the outer walls of the two test end rods 16 respectively, forming a connected state, and then the two sensor ends of the monitor are respectively plugged into the two device docking ends 19, so that the docking installation operation of the monitor can be realized.

When the AC power supply 25 is selected, the AC current that can be rotated is supplied to the two power supply terminals 23 through the controller 28, and the power supply terminals 23 are supplied to the connecting wire 22, and the connecting wire 22 is supplied to the power-on ring 9, and the specified AC test detection current is applied to the two power-on rings 9.

[0046] Then, when the present invention performs the spacing linkage test, the electric cylinder 2 is started by starting the controller 28, the support platform 1 supports the electric cylinder 2, the electric cylinder 2 can drive the hinge block 3 to move forward, the hinge block 3 drives the two connecting shafts 4 to move forward, and the two connecting shafts 4 respectively drive the front end parts of the two sleeve rods 5 to move forward. At the same time, the sleeve rod 5 drives the support shaft 6 to move right, and the other sleeve rod 5 drives the other support shaft 6 to move left, the two support shafts 6 approach each other, the support shaft 6 drives the sleeve block 7 to move right, the sleeve block 7 drives the concave support plate 8 to move right, and the concave support plate 8 drives the power ring 9 to move right. At the same time, the concave support plate 8 drives the groove ring 10 to move right, the energized ring 9 makes the rotating frame 12 move right, the rotating frame 12 drives the driven gear 11 to move right, the rotating frame 12 drives the screw 30 to move right, and the screw 30 drives the threaded sleeve 31 to move right, the threaded sleeve 31 makes the bearing sleeve 32 move right, the bearing sleeve 32 drives the energized ball 33 to move right along the outer wall of the test end rod 16, and at the same time, another energized ball 33 moves to the left along the outer wall of the other test end rod 16.

[0047] At the same time, the controller 28 starts the two reduction motors 15, and the two reduction motors 15 drive the two transmission shafts 13 to rotate respectively. The transmission shaft 13 drives the driving gear 14 to mesh and rotate, and the driving gear 14 carries the driven gear 11 to rotate, and the driven gear 11 drives the rotating frame 12 to rotate, and the rotating frame 12 makes the screw 30 rotate, and the screw 30 drives the threaded sleeve 31 to rotate the bearing sleeve 32. At the same time, the bearing sleeve 32 drives the energized ball 33 to rotate and move along the outer wall of the test end rod 16 to change the angle.

[0048] In this way, not only the distance between the two energized balls 33 is constantly changing and moving, but also the rotation angle position of the two energized balls 33 is constantly changing, the interference test detection current is guided to the rotating frame 12 through the energized ring 9, the rotating frame 12 is guided to the screw 30, the screw 30 is guided to the threaded sleeve block 31, the threaded sleeve block 31 is guided to the bearing sleeve block 32, the bearing sleeve block 32 is guided to the energized balls 33, the energized balls 33 guide the interference test detection current to the test end rod 16, the insulating column 17 is supported by the electric cylinder 2, the insulating column 17 isolates the two test end rods 16, and the test The test end rod 16 then guides the interference test detection current to the socket terminal 18, and the socket terminal 18 guides it to the collection resistor 20. After the changes are collected by the collection resistor 20, it is transmitted to the monitoring device by the equipment docking terminal 19. In this way, the interference signals caused by the interference test detection currents of different intervals and the interference signals caused by the interference test detection currents of different angles will affect the monitoring equipment. If the monitor does not generate an alarm, the anti-interference ability is better. Once a false alarm occurs, the electric cylinder 2 is shut down by the controller 28 and the two reduction motors 15 are shut down at the same time.

[0049] Finally, when the present invention performs precise positioning, when the rotating frame 12 rotates, the rotating frame 12 will drive the linkage column 34 to rotate, and the linkage column 34 will drive the rotating rod 35 to rotate, and the rotating rod 35 will drive the angle rotating shaft 36 to rotate. The center point of the angle rotating shaft 36 is on the same horizontal line as the center point of the test end rod 16, so the angle rotating shaft 36 can drive the sensing end of the angle sensor 37 to rotate. At the same time, the concave support plate 8 supports the bracket 38, and the bracket 38 provides support force for the angle sensor 37, so that the angle sensor 37 can realize angle sensing of the angle rotating shaft 36. When the two reduction motors 15 are turned off, the rotating frame 12 will also stop rotating, so that the angle sensor 37 can realize angle sensing of the angle rotating shaft 36, and the angle position that fails the anti-interference can be recorded at this time.

[0050] At the same time, when the two socket blocks 7 are close to each other, the socket blocks 7 will drive the sensing block 39 to approach the distance sensor 40, and the distance sensor 40 will realize distance sensing of the sensing block 39. When the electric cylinder 2 is closed, the distance sensor 40 will sense the distance between the distance sensor 40 and the sensing block 39, and the anti-interference test detection distance value between the center contact points of the two energized balls 33 will be known, and the specific spacing value of the anti-interference test detection of the monitor and the distance angle value of the anti-interference test detection can be accurately grasped, so as to realize accurate testing and detection of anti-interference ability.
