Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of video sensor detection, and particularly relates to a video sensor stability test device. Background Art
[0002] A video sensor uses the photoelectric conversion function of optoelectronic devices to convert the optical image on the photosensitive surface into an electrical signal that is in a corresponding proportional relationship with the optical image. Most cameras rely on the support of video sensors. Therefore, the stability during the operation of the video sensor 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 prior art, during the detection of most video sensors, only regular shaking can be performed to simulate the state of the video sensor under vibration. However, most vibrations, such as those caused by wind, are irregular, resulting in the inability of conventional test devices to reflect the actual working stability. In addition, temperature and humidity changes caused by the weather can also lead to unstable working states of video sensors. During the stability test of conventional devices, vibration and temperature and humidity changes are usually carried out separately, and the results obtained cannot accurately reflect the stability of the video sensor.

[0091] The following is combined with Figures 1 to 9 The embodiment of the present invention provides a video sensor stability test device, including:
[0092] A table body 1, and four conveying components are arranged on one side of the top of the table body 1;
[0093] A fixed box 2, the fixed box 2 is connected to the four conveying components, and an installation component is arranged inside the fixed box 2 for fixing the video sensor;
[0094] A plurality of power components, the plurality of power components are arranged equidistantly on the top of the table body 1, and the plurality of power components are all below the fixed box 2, and the plurality of power components are all fixed to the fixed box 2, and the plurality of power components are used to shake the fixed box 2 disorderly;
[0095] The temperature and humidity adjustment box 16 is fixed at the bottom of the table body 1. A heating component is arranged inside the temperature and humidity adjustment box 16, and a humidifying component is arranged at the bottom of the temperature and humidity adjustment box 16. One end of each of the four conveying components is communicated with the temperature and humidity adjustment box 16, and the other end of each of the four conveying components is communicated with the fixed box 2;
[0096] A circulation component is fixed on the side wall of the temperature and humidity adjustment box 16. The circulation component is communicated with the temperature and humidity adjustment box 16 and is used to drive the gas circulation inside the temperature and humidity adjustment box 16;
[0097] A vibration component is fixed on the side wall of the fixed box 2. The vibration component is connected to the installation component and is also connected to the circulation component.
[0098] Through the random control of multiple power components, the fixed box 2 is shaken disorderly to simulate the actual situation, ensuring the accuracy of the test;
[0099] Through the action of the circulation component and the conveying components, the adjustment box 16 can be communicated with the fixed box 2. By changing the temperature and humidity in the adjustment box 16, the temperature and humidity in the fixed box 2 are changed to simulate the working environment of the video sensor under different temperatures and humidities, further ensuring the accuracy of the test.
[0100] Furthermore, the conveying component includes:
[0101] Two first ball heads 27, one of the first ball heads 27 is fixed to the bottom of the fixed box 2, and the other first ball head 27 is fixed to the top of the table body 1;
[0102] Two first spherical seats 26 are respectively rotatably connected to the two first ball heads 27;
[0103] The second sleeve 6 is fixed to one of the first spherical seats 26;
[0104] The first piston 28 is slidably arranged inside the second sleeve 6;
[0105] The second sleeve rod 25 is fixed to the top of the first piston 28;
[0106] The first spring 29, one end of the first spring 29 is fixed to the inner wall of the bottom of the second sleeve 6, and the other end of the first spring 29 is fixed to the first piston 28;
[0107] Two first one-way valves 30 are both arranged through the side wall of the second sleeve 6;
[0108] Two conveying pipes 31 are respectively communicated with the two first one-way valves 30. One of the conveying pipes 31 is communicated with the temperature and humidity adjustment box 16, and the other conveying pipe 31 is communicated with the fixed box 2;
[0109] 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.
[0110] As the fixed box 2 shakes, the second sleeve rod 25 reciprocates on the second sleeve 6. Due to the action of the first piston 28, the volume of the space below the first piston 28 in the second sleeve 6 periodically increases and decreases. When the volume of this space rises, 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. When the volume of this space shrinks, the gas in the second sleeve 6 enters the fixed box 2 through the other set of first one-way valves 30 and delivery pipes 31, thereby changing the temperature and humidity of the gas in the temperature and humidity adjustment box 16 to change the temperature and humidity of the gas in the fixed box 2.
[0111] Furthermore, the installation assembly includes:
[0112] Two second guide rails 45, both of which are fixed on the inner wall of the bottom of the fixed box 2;
[0113] Two second sliders 46, which are respectively slidably connected to the two second guide rails 45;
[0114] The mounting plate 44 is fixed to the two second sliders 46, and a plurality of threaded posts are provided on the top of the mounting plate 44;
[0115] The transparent plate 3 is hinged to the side wall of the fixed box 2.
[0116] Furthermore, the power assembly includes:
[0117] The electric slide table 4 is fixed on the top of the table body 1;
[0118] The first guide rail 32 is fixed to the bottom of the fixed box 2;
[0119] The first slider 33 is slidably connected to the first guide rail 32;
[0120] Two second ball heads 34, one of the second ball heads 34 is fixed to the first slider 33, and the other second ball head 34 is fixed to the moving end of the electric slide table 4;
[0121] Two second spherical seats 35, which are respectively rotatably connected to the two second ball heads 34;
[0122] The third sleeve 37 is fixed to one of the second spherical seats 35. A third sleeve rod 36 is slidably arranged in the third sleeve 37. A sealing ring is sleeved on the third sleeve rod 36, and the sealing ring abuts against the inner wall of the third sleeve 37. The third sleeve rod 36 is fixed to the other second spherical seat 35;
[0123] The second spring 42 has one end fixed to the inner wall of the bottom of the third sleeve 37 and the other end fixed to the third sleeve rod 36;
[0124] The solenoid valve 38 is arranged through the side wall of the third sleeve 37;
[0125] Two negative pressure components are both fixed to the moving end of the electric sliding table 4.
[0126] Through the contraction between the third sleeve 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 switch of the random electric sliding table 4 is turned on and the switch time is random, the position and magnitude of the pulling force received at the bottom of the fixed box 2 are both random. Through the rotation between the first ball head 27 and the first spherical seat 26, and the expansion and contraction between the second sleeve rod 25 and the second sleeve 6, the fixed box 2 can shake completely randomly, and then the stability of the video sensor is detected under the condition of random shaking.

[0128] The first sleeve 5 is fixed to the moving end of the electric sliding table 4;
[0129] The third piston 56 is slidably arranged in the first sleeve 5;

[0136] Randomly turn on the switch of one of the electric sliding tables 4, and the duration of the turn-on is random. During the operation of the electric sliding table 4, it drives the two first sleeves 5 to move. Under the action of the first sleeve rod 40, the L-shaped plate 41 and the third piston 56, the air pressure inside one of the first sleeves 5 rises and is discharged through the second one-way valve 43, while the air pressure inside the other first sleeve 5 decreases. Subsequently, turn on the switch of the second spring 42, so that the third sleeve 37 is connected to the first sleeve 5 through the second spring 42, the three-way pipe 39. Since the air pressure in this first sleeve 5 is relatively low, the air pressure in the third sleeve 37 decreases, and then the third sleeve rod 36 is driven to contract into the third sleeve 37 under the action of the sealing ring on the third sleeve 37.
[0137] Furthermore, the heating component includes:

[0147] When it is necessary to adjust the humidity in the temperature and humidity adjustment box 16, 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 pipe body 22 is input into the annular seat 24 through the connecting pipe 23 and sprayed out through the nozzle 53. Along with the airflow, the water mist adheres to the mesh cloth between the first annular frames 51 along with the airflow, and the water on the mesh cloth evaporates along with the airflow to increase the temperature and humidity of the gas in the temperature and humidity adjustment box 16.

Under the sliding action of the second slider 46 and the second guide rail 45, the mounting plate 44 is pulled out of the fixed box 2, and the video sensor is fixed to the threaded post of the mounting plate 44. Then, push the mounting plate 44 back to its original position and close the transparent plate 3. After the mounting plate 44 is reset, the magnet on the connecting frame 47 adsorbs the mounting plate 44 to achieve the fixation between the mounting plate 44 and the connecting frame 47;
[0167] When performing the shaking test, randomly turn on the switch of one of the electric slides 4, and the on-time is random. During the operation of the electric slide 4, it drives the two first sleeves 5 to move. Under the action of the first sleeve rod 40, the L-shaped plate 41 and the third piston 56, the air pressure inside one of the first sleeves 5 rises and is discharged through the second one-way valve 43, while the air pressure inside the other first sleeve 5 decreases. Then, turn on the switch of the second spring 42, so that the third sleeve 37 is connected to the first sleeve 5 through the second spring 42, the three-way pipe 39. Since the air pressure in this first sleeve 5 is low, the air pressure in the third sleeve 37 decreases, and then drives the third sleeve rod 36 to contract into the third sleeve 37 through the action of the sealing ring on the third sleeve 37. Through 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 switch of the randomly connected electric slide 4 is turned on and the switch time is random, the position and magnitude of the pulling force received at the bottom of the fixed box 2 are both random. Through the rotation between the first ball head 27 and the first spherical seat 26, and the telescoping of the second sleeve rod 25 and the second sleeve 6, the fixed box 2 can perform completely random shaking, and then the stability of the video sensor is detected under random shaking conditions;
[0168] Subsequently, turn on the switch of the motor 8. When the motor 8 operates, it drives the shaft body 9 to rotate. During the rotation of the shaft body 9, the elliptical disk 10 is driven to rotate. Through the connecting groove 49 on the elliptical disk 10 and the transmission seat 48, the connecting frame 47 is driven to reciprocate, and then the mounting plate 44 is driven to reciprocate in the fixed box 2, so as to cooperate with the fixed box 2 without shaking, and further test the stability of the video sensor under shaking conditions;
[0169] During the rotation of the shaft body 9, the centrifugal fan is driven to work through the universal joint 11, the prism 50 and the transmission shaft 13. During the operation of the centrifugal fan, the gas at the four corner positions in the temperature and humidity adjustment box 16 is extracted through the two connecting pipes 17 and the suction pipe 18, and the gas is injected into the middle part of the temperature and humidity adjustment box 16 through the air supply pipe 19, so as to realize the circulation of the gas in the temperature and humidity adjustment box 16;
[0170] According to the test requirements, turn on the switch of the heating wire. When the air flow 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 adjustment box 16 rises. When it is necessary to adjust the humidity in the temperature and humidity adjustment box 16, turn on the switch of the electric push rod 21. When the electric push rod 21 operates, it pushes the second piston 54 to move, and then the water in the pipe body 22 is input into the annular seat 24 through the connecting pipe 23 and sprayed out through the nozzle 53. Along with the air flow, the water mist adheres to the mesh cloth between the first annular frames 51 along with the air flow, and the water on the mesh cloth evaporates along with the air flow to increase the temperature and humidity of the gas in the temperature and humidity adjustment box 16;
[0171] Record the temperature and humidity of the gas in the temperature and humidity adjustment box 16 and keep them. Along with the shaking of the fixed box 2, the second sleeve rod 25 reciprocates in 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 periodically increases and decreases. When the volume of this space rises, the gas in the temperature and humidity adjustment box 16 enters the second sleeve 6 through one group of delivery pipes 31 and the first one-way valve 30. When the volume of this space shrinks, the gas in the second sleeve 6 enters the fixed box 2 through the other group of first one-way valves 30 and the delivery pipes 31. By changing the temperature and humidity of the gas in the temperature and humidity adjustment box 16, the temperature and humidity of the gas in the fixed box 2 are changed, and thus the stability of the video sensor under different temperature and humidity conditions can be tested.
