Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of video sensor detection, and in particular to a video sensor stability testing device. Background Art
[0002] Video sensors use the photoelectric conversion function of photoelectric devices to convert the light image on the photosensitive surface into an electrical signal that is proportional to the light image. Most cameras cannot do without the support of video sensors. Therefore, the stability of the video sensor during operation directly affects the working quality of the camera. In order to detect the stability of the video sensor, a video sensor stability test device is proposed.
[0003] In the existing technology, most video sensors can only be shaken regularly during the detection process to simulate the state of the video sensor being vibrated. However, most vibrations, such as those caused by wind, are irregular, resulting in the inability of conventional testing equipment to reflect the actual working stability. In addition, changes in temperature and humidity caused by weather can also cause the working state of the video sensor to be unstable. During the stability test of conventional equipment, vibration and temperature and humidity changes are usually performed separately, and the results obtained cannot accurately reflect the stability of the video sensor.

[0096] The vibration component is fixed on the side wall of the fixed box 2, the vibration component is connected to the installation component, and the vibration component is connected to the circulation component.
[0097] Through the random control of multiple power components, the fixed box 2 is shaken randomly to simulate the actual situation and ensure the accuracy of the test;
[0098] Through the action of the circulation component and the conveying component, the regulating box 16 can be connected to the fixed box 2.

[0099] Furthermore, the conveying assembly includes:
[0100] Two first ball heads 27, one of which is fixed to the bottom of the fixing box 2, and the other is fixed to the top of the platform 1;

[0105] A first spring 29, one end of the first spring 29 is fixed to the bottom inner wall of the second sleeve 6, and the other end of the first spring 29 is fixed to the first piston 28;
[0106] Two first one-way valves 30 , both of which are disposed through the side wall of the second sleeve 6 ;
[0107] Two delivery pipes 31, the two delivery pipes 31 are connected to the two first one-way valves 30 respectively, one delivery pipe 31 is connected to the temperature and humidity adjustment box 16, and the other delivery pipe 31 is connected to the fixed box 2;
[0108] The return pipe 15 has one end connected to the fixed box 2 and the other end connected to the temperature and humidity adjustment box 16 .
[0109] As the fixed box 2 shakes, the second sleeve rod 25 moves back and forth on the second sleeve 6. Through the action of the first piston 28, the volume of the space below the first piston 28 in the second sleeve 6 increases and decreases periodically. When the volume of the space increases, the gas in the temperature and humidity adjustment box 16 enters the second sleeve 6 through one set of delivery pipes 31 and the first one-way valve 30.

[0114] The transparent plate 3 is hinged on the side wall of the fixed box 2.
[0115] Furthermore, the power assembly includes:
[0116] The electric slide 4 is fixed on the top of the platform 1;
[0117] A first guide rail 32, the first guide rail 32 is fixed to the bottom of the fixed box 2;
[0118] A first slider 33 , the first slider 33 is slidably connected to the first guide rail 32 ;

[0120] Two second spherical seats 35, the two second spherical seats 35 are rotatably connected to the two second ball heads 34 respectively;
[0121] A third sleeve 37 is fixed to one of the second spherical seats 35. A third rod 36 is slidably disposed in the third sleeve 37.

[0125] Through the contraction between the third rod 36 and the third sleeve 37, and the rotation between the second ball head 34 and the second spherical seat 35, the fixed box 2 is subjected to a downward pulling force. Since the random electric slide 4 is turned on and off, and the switching time is random, the position and size of the pulling force on the bottom of the fixed box 2 are random. Through the rotation between the first ball head 27 and the first spherical seat 26, and the expansion and contraction between the second rod 25 and the second sleeve 6, the fixed box 2 can be shaken completely randomly, and the stability of the video sensor can be detected under the random shaking condition.

[0144] The connecting tube 23 has one end connected to the annular seat 24 and the other end connected to the tube body 22 .
[0145] When the humidity in the temperature and humidity regulating box 16 needs to be adjusted, the switch of the electric push rod 21 is turned on.

Along with the airflow, the water mist adheres to the mesh between the first annular frame 51.

After the mounting plate 44 is returned to its original position, the magnet on the connecting frame 47 attracts the mounting plate 44, so that the mounting plate 44 and the connecting frame 47 are fixed together;
[0165] When performing the shaking test, the switch of one of the electric slides 4 is randomly turned on, and the duration of the switch-on is random. During the operation of the electric slide 4, the two first sleeves 5 are driven to move. Under the action of the first sleeve rod 40, the L-shaped plate 41 and the third piston 56, the internal air pressure of one of the first sleeves 5 rises and is discharged through the second one-way valve 43, while the internal air pressure of the other first sleeve 5 is reduced, so that the third sleeve 37 is connected to the first sleeve 5 through the three-way pipe 39. Since the air pressure in the first sleeve 5 is lower, the air pressure in the third sleeve 37 is reduced, and then the air pressure on the third sleeve 37 is discharged. The sealing ring drives the third rod 36 to retract into the third sleeve 37. The rotation between the second ball head 34 and the second spherical seat 35 causes the fixed box 2 to be pulled downward. Since the random electric slide 4 is turned on and off at random times, the position and magnitude of the pulling force on the bottom of the fixed box 2 are random. The rotation between the first ball head 27 and the first spherical seat 26, and the expansion and contraction between the second rod 25 and the second sleeve 6, allow the fixed box 2 to shake completely randomly, thereby testing the stability of the video sensor under random shaking conditions.
[0166] Then, the motor 8 is turned on. When the motor 8 is working, the shaft 9 is driven to rotate. During the rotation of the shaft 9, the elliptical disk 10 is rotated. The connecting frame 47 is driven to move back and forth through the connecting groove 49 and the transmission seat 48 on the elliptical disk 10, and then the mounting plate 44 is driven to move back and forth in the fixed box 2, so as to achieve the coordination with the fixed box 2 without shaking, and further test the stability of the video sensor under shaking conditions;
[0167] During the rotation of the shaft 9, the centrifugal fan is driven by the universal joint 11, the prism 50 and the transmission shaft 13. During the operation of the centrifugal fan, the gas at the four corners of the temperature and humidity control box 16 is extracted through the two connecting pipes 17 and the exhaust pipe 18, and the gas is injected into the middle part of the temperature and humidity control box 16 through the air supply pipe 19, thereby realizing the circulation of the gas in the temperature and humidity control box 16.
[0168] According to the test requirements, the switch of the heating wire is turned on. When the airflow passes through the heating wire on the second annular frame 52, it is heated, so that the temperature of the gas in the temperature and humidity control box 16 increases. When the humidity in the temperature and humidity control box 16 needs to be adjusted, the switch of the electric push rod 21 is turned on. When the electric push rod 21 works, it pushes the second piston 54 to move, and then the water in the tube body 22 is input into the annular seat 24 through the connecting pipe 23, and then sprayed out through the nozzle 53. Along with the airflow, the water mist adheres to the mesh between the first annular frame 51. The water on the mesh evaporates with the airflow to increase the temperature and humidity of the 16 gases in the temperature and humidity control box.
[0169] The temperature and humidity of the gas in the temperature and humidity regulating box 16 are recorded and maintained. As the fixed box 2 shakes, the second set of rods 25 moves back and forth on the second sleeve 6. Through the action of the first piston 28, the volume of the space below the first piston 28 in the second sleeve 6 increases and decreases periodically. When the volume of the space rises, the gas in the temperature and humidity regulating box 16 enters the second sleeve 6 through one set of delivery pipes 31 and the first one-way valve 30. When the volume of the space decreases, the gas in the second sleeve 6 enters the fixed box 2 through the other set of first one-way valves 30 and the delivery pipe 31. By changing the temperature and humidity of the gas in the temperature and humidity regulating box 16, the temperature and humidity of the gas in the fixed box 2 can be changed, and the stability of the video sensor under different temperature and humidity conditions can be tested.
