Outdoor hunting camera is a low-power consumption electronic product, and most of the time is in a dormant state, when someone or animal passes by, PIR in the camera wakes up the camera to work after sensing the temperature difference change. When an animal passes continuously, the camera needs to trigger the photographing function continuously, and the recovery time between the first photo and the second photo needs to be strictly controlled so as to reduce the possibility of missed photographing. In order to test the PIR recovery time of a camera, a worker is required to continuously shake the PIR in front of the PIR by hand in the process to start the camera to work; when the camera enters a dormant state, the PIR wakes the camera to finish photographing or video after sensing the temperature of the human body, and the camera enters the dormant state again and photographs or video after being waken to finish one period of work; and transmitting the photos or videos shot by the camera to a computer, and acquiring the time of the adjacent pictures or videos on the watermark by the computer to calculate an interval time difference, namely PIR recovery time of the camera. However, during the testing process, a worker needs to shake the PIR in front of the PIR continuously by hand to turn on the camera, so that the worker is tired, which is unfavorable for long-time operation, and the interval time is unstable and has a neutral position, which results in errors in the tested data, and part of the images shot by the hunting camera 30 have no time watermark, which results in failure to complete the testing.
In order to solve the above problems, the present invention proposes a PIR recovery time testing apparatus for testing a hunting camera 30, which starts shooting and outputs a corresponding image signal when a heating object is detected by the hunting camera 30.
Referring to fig. 1 and 3, in an embodiment of the present invention, the PIR recovery time testing apparatus includes:
a housing provided with a containing cavity 1 and an opening 2 communicated with the containing cavity 1, wherein the opening 2 is horizontally opposite to the hunting camera 30;
the heat source assembly 10 is arranged in the accommodating cavity 1, and the heat source assembly 10 is used for radiating heat with preset temperature to the environment through the opening 2 during operation;
a heat source shielding assembly 20, wherein the heat source shielding assembly 20 is used for moving to the opening 2 at a preset frequency in operation so as to shield the heat source assembly 10 from radiating heat of a preset temperature to the environment;
the timing display 50 is arranged above the shell, and the timing display 50 is used for timing and displaying time so as to obtain shooting time when the hunting camera 30 shoots;
and a test terminal 40, wherein a receiving end of the test terminal 40 is connected with the hunting camera 30, the test terminal 40 is configured to receive the image signals when the heat source assembly 10 and the fan assembly work, obtain photographing time of two adjacent images, and perform differential calculation to calculate a time difference between the two adjacent images.
In this embodiment, the accommodating cavity 1 in the housing may be used for accommodating the heat source assembly 10, and the wall of the accommodating cavity 1 may prevent the heat source assembly 10 from radiating heat of a preset temperature to the environment, that is, the heat source assembly 10 radiates heat of the preset temperature to the environment only through the opening 2 connected with the accommodating cavity 1, so when the opening 2 is sealed, the heat source assembly 10 cannot radiate heat to the environment at all, that is, the hunting camera 30 cannot detect heat radiated by the heat source assembly 10 to the environment and is in a dormant state; when hunting camera 30 detects heat from heat source assembly 10 radiating to the environment, it wakes up to take a photograph of heat source assembly 10 and timing display 50.
In this embodiment, the heat source assembly 10 may be implemented using any heat source assembly 10 that simulates the body temperature of an animal, such as a heat patch or the like. It will be appreciated that heat source assembly 10 may continue to generate heat during operation, and that the temperature of heat source assembly 10 may be maintained between 40 degrees and 60 degrees, simulating the body temperature of an animal, to wake up hunting camera 30, and capture images of heat source assembly 10 and timing display 50.
In this embodiment, the timing display 50 may be implemented by any timing display 50 that can time and display time, such as a millisecond-scale stopwatch, which is continuously timed and is on the same side as the heat source assembly 10. It will be appreciated that when the hunting camera 30 detects the heat radiated by the heat source assembly 10 to start shooting, the hunting camera 30 shoots the time displayed by the timer display 50 disposed above the casing in addition to shooting the heat source assembly 10, so that in the case that the image shot by the hunting camera 30 has no time watermark, the hunting camera 30 can shoot the shooting time displayed by the timer display 50, so that the testing terminal 40 can obtain the shooting time of two adjacent images and perform differential calculation to calculate the interval time difference between the two adjacent images, i.e. the PIR recovery time of the hunting camera 30.
In this embodiment, the heat source shielding assembly 20 may be implemented by any heat source shielding assembly 20, such as a fan, that can block the heat source assembly 10 from radiating heat to the environment through the opening 2. The test terminal 40 may be implemented by a host computer. It will be appreciated that, when the heat source shielding assembly 20 is operated, it is moved to the opening 2 according to the preset frequency to shield the heat source assembly 10 from radiating heat of the preset temperature to the environment, which is equivalent to generating a stable intermittent heat source assembly 10, after the hunting camera 30 is awakened, shooting the heat source bank price and the timing display 50, and sending corresponding image signals to the test terminal 40, the test terminal 40 obtains the shooting time of two adjacent images, and calculates the difference value of the shooting time of two adjacent images, thereby calculating the interval time difference of two adjacent images, i.e. the PIR recovery time of the hunting camera 30. The PIR recovery time testing device is more stable in time interval than if a worker shakes his hands in front of the hunting camera 30 to perform a test, so that errors in the measured data are smaller; and the test terminal 40 can directly obtain the shooting time of the shot image, so as to solve the problem that the test cannot be performed due to the fact that the image shot by the hunting camera 30 has no time watermark.
When the heat source assembly 10 and the heat source shielding assembly 20 in the PIR recovery time testing device work, the testing terminal 40 obtains the shooting time of two images according to the image signals, performs differential value calculation to calculate the interval time difference of two adjacent images, and simulates that animals or people pass through the heat source assembly 10 and the fan assembly to wake up the hunting camera 30, so that the stability of interval time is ensured, the error of tested data is further reduced, and the quality of the products produced by the hunting camera 30 is improved; and solves the problem that the image shot by part of the hunting cameras 30 cannot be tested without a time watermark.
Referring to fig. 2 and 3, in one embodiment, the heat source shielding assembly 20 includes:
a fan assembly having at least one fan blade 22, the fan assembly being configured to rotate the fan blade 22 at a predetermined frequency during operation, each fan blade 22 being configured to shield the heat source assembly 10 from radiating heat at a predetermined temperature to the environment when rotated to the opening 2.
In this embodiment, the fan assembly is operated to drive the fan blades 22 to rotate at a predetermined frequency. It can be understood that when the fan 22 is a three-blade fan 22, the fan 22 rotates at a frequency of 1 time/second to shield the heat source assembly 10 from radiating heat of a preset temperature to the environment, i.e. when one of the fan 22 rotates to the opening 2 of the accommodating cavity 1, the fan 22 rotating to the opening 2 shields the heat source assembly 10 from radiating heat to the environment, i.e. the hunting camera 30 detects the heat radiated by the heat source assembly 10 to be in a dormant state; when the fan blade 22 at the opening 2 is turned away, that is, when there is no fan blade 22 at the opening 2, the heat source assembly 10 radiates heat outwards through the opening 2, and the hunting camera 30 detects the heat radiated by the heat source assembly 10 to the environment to start shooting.
In practical applications, the area of the fan blade 22 is the same as the area of the opening 2. It will be appreciated that, when the fan blade 22 is rotated to the opening 2, the heat source assembly 10 can be completely shielded from the heat radiated to the environment, i.e. the hunting camera 30 can not completely detect the heat radiated to the environment by the heat source assembly 10, so that the hunting camera 30 is in a dormant state.

Referring to fig. 2, in an embodiment, the PIR recovery time testing apparatus further includes a temperature controller 60, an output end of the temperature controller 60 is connected to the heat source assembly 10, and the temperature controller 60 is used for controlling the heat source assembly 10 to work so as to radiate heat of a preset temperature to the environment.

It will be appreciated that the thermostat 60 may control the operation of the heat source assembly 10, i.e., control the heat source assembly 10 to emit heat at a predetermined temperature to the environment, simulating the passage of an animal to trigger the hunting camera 30 to start shooting.
In one embodiment, the PIR recovery time testing arrangement includes a test stand for placement of the hunting camera 30.
