Detailed ways

In order to provide a realization scheme that can achieve the visual effect of invisible infrared light sources, the embodiment of the present invention provides an infrared night vision device, a control method, and a control device. The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that , the preferred embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Example 1:

Embodiment 1 of the present invention provides an infrared night vision device, as shown in Figure 2, including an infrared lamp and a filter, the filter is located on the light emitting side of the infrared lamp, and is used to filter out the wavelength band that the human eye can perceive in the spectrum of the infrared lamp spectrum.

Preferably, the wavelength of the infrared light in the infrared night vision device provided by the embodiment of the present invention may be greater than 900nm. The spectral center of infrared lamps with a wavelength greater than 900nm is farther away from the wavelength band that the human eye can perceive, and the spectral energy is more concentrated, so the brightness that the human eye can perceive is also smaller.

As far as the existing technology is concerned, the response spectrum of the photosensitive device in infrared night vision equipment is also limited. Generally speaking, the photosensitive device does not respond well to light with a wavelength above 1000nm. Therefore, in the current implementation, the wavelength of 900nm can be used. -1000nm infrared lamps, for example, infrared lamps with a wavelength of 940nm can be used, which is easier to implement.

In order to achieve the visual effect of the invisible infrared light source, the infrared night vision device provided by the embodiment of the present invention is equipped with a filter on the light emitting side of the infrared lamp to filter out the spectrum of the band that the human eye can perceive. The filter can specifically be a high-pass filter , can also be a bandpass filter.

For example, when the infrared night vision device provided by the embodiment of the present invention uses an infrared lamp with a wavelength of 940nm, the additional filter may specifically select a high-pass filter with a passing wavelength of 940nm.

In specific implementation, the above-mentioned filter can be realized by using a filter lens, which is more convenient for implementation.

Generally, the infrared lamp in the infrared night vision device will be located around the lens in the infrared night vision device. Therefore, a filter lens can be installed outside the infrared lamp and the lens as a whole, and the structural reliability is higher.

The infrared lamp is composed of a lamp cup and a lamp bead, and a small piece of filter lens can also be installed on the lamp cup of each infrared lamp to reduce the area of the filter lens used and lower the cost. That is, there is a filter lens on the light emitting side of each infrared lamp and the lamp cup of the infrared lamp. Preferably, the filter lens is perpendicular to the lamp axis of the infrared lamp.

It can be seen that the infrared night vision device provided by the embodiment of the present invention can achieve the visual effect of invisible infrared light source, can make the infrared night vision device suitable for more application scenarios, and is easy to implement.

In the infrared night vision device provided by the embodiment of the present invention, the number of infrared lamps may be one or multiple, which is not limited in the present invention.

Example 2:

Embodiment 2 of the present invention provides a control method for an infrared night vision device. As shown in FIG. When they are exactly the same, the control method can be adopted, which can specifically include the following steps:

Step 301, when the infrared night vision device is in a working mode that needs to turn on the infrared light, obtain the current focusing distance of the infrared night vision device;

Step 302 , according to the current focusing distance and the irradiation distance of the multiple infrared lamps in the infrared night vision device, control the working states of the multiple infrared lamps.

Because the lamp cups of infrared lamps have different focusing angles or different rated powers, even infrared lamps with the same wavelength may have different irradiation distances. Setting infrared lamps with different irradiation distances in infrared night vision equipment can be applied to more application scenarios. For example, as shown in Figure 4, infrared lamps with three different irradiation distances of low beam, medium beam and high beam can be set. The distance is less than the irradiation distance of the high beam. Of course, the number of infrared lamps for each irradiation distance can be one or more.

The focusing distance of infrared night vision equipment is the focusing distance of the lens of infrared night vision equipment. General infrared night vision devices have an auto-focus function, so the current focus distance of the infrared night vision device can be obtained.

Specifically, step 302 controls the working status of the plurality of infrared lamps according to the current focusing distance and the irradiation distance of the plurality of infrared lamps in the infrared night vision device, which may specifically include:

Among the infrared lamps whose irradiation distance is greater than the current focusing distance, determine the infrared lamp with the smallest irradiation distance; control at least one of the determined infrared lamps to be on, and the other infrared lamps to be off, that is, infrared night vision Among the multiple infrared lamps of the device, all the infrared lamps except the at least one infrared lamp are turned off.

If among the infrared lamps whose irradiation distance is greater than the current focusing distance, there is only one infrared lamp with the smallest irradiation distance determined, then the determined infrared lamp is controlled to be in the on state, except for the plurality of infrared lamps that the infrared night vision device has All other infrared lamps except the determined one are in off state.

If among the infrared lamps whose irradiation distance is greater than the current focusing distance, there are more than one infrared lamps with the smallest irradiation distance determined, then some of the determined infrared lamps can be controlled to be on, and the infrared night vision device has Among the multiple infrared lamps, all other infrared lamps except this part of the infrared lamps are in the off state; it is also possible to control all the determined infrared lamps to be in the on state. All other infrared lamps except the lamp are turned off. Specifically, it can be determined based on comprehensive consideration of various requirements such as illumination effects, device power consumption, and invisibility effects in actual application scenarios, and is not specifically limited in the present invention.

Further, when there is no infrared lamp whose irradiation distance is greater than the current focus distance, that is, when the target object has exceeded the irradiation range of all infrared lamps, the infrared lamp with the largest irradiation distance among the plurality of infrared lamps can be controlled to be turned on at this time , you can also control all the infrared lamps to be on, so as to ensure the irradiation effect as much as possible.

If the above-mentioned plurality of infrared lamps include low beam, medium beam and high beam; then, when the current focus distance is greater than or equal to the irradiation distance of the medium beam, only the high beam can be controlled to be on; when the current focus distance is less than When the irradiation distance of the medium beam is greater than or equal to the irradiation distance of the low beam, only the medium beam can be controlled to be on; when the current focus distance is less than the illumination distance of the low beam, only the low beam can be controlled to be on .

Further, step 302 controls the working status of the plurality of infrared lamps according to the current focusing distance and the irradiation distance of the plurality of infrared lamps in the infrared night vision device, which may specifically include:

According to the current focusing distance, control the power of the infrared lamp in the on state, that is, control the brightness of the infrared lamp in the on state; wherein, the smaller the current focusing distance is, the smaller the power of the infrared lamp in the on state is, and the darker the infrared lamp is.

Taking the control of the infrared light in the infrared night vision device shown in Figure 4 as an example, the control method of the infrared light of the infrared night vision device is illustrated below, assuming that the irradiation distance of the low beam is 10m, and the irradiation distance of the medium beam is 20m, and the irradiation distance of the high beam is 30m, the specific control process can be shown in Figure 5, including the following steps:

Step 501. Obtain the current focusing distance of the infrared night vision device.

Step 502, judging whether the current focus distance is greater than or equal to 20m.

If the current focus distance is greater than or equal to 20m, enter step 503;

If the current focus distance is less than 20m, go to step 504.

Step 503 , only control the high beam to be on, and the closer the current focus distance is to 20m, the smaller the power of the high beam is controlled.

This control flow ends.

Step 504, judging whether the current focus distance is greater than or equal to 10 m.

If the current focus distance is greater than or equal to 10m, enter step 505;

If the current focus distance is less than 10m, go to step 506.

Step 505 , only controlling the medium beam lamp to be in the on state, and the closer the current focus distance is to 10 m, the lower the power of the medium beam lamp is controlled.

This control flow ends.

Step 506 , only controlling the low beam to be on, and the smaller the current focus distance is, the smaller the power of the middle beam is controlled.

This control flow ends.

Further, for the infrared night vision device, its working mode includes not only the working mode that needs to turn on the infrared light, but also the working mode that does not need to turn on the infrared light. The operating mode of the infrared night vision device can be manually controlled by the operator, or controlled by the infrared night vision device according to the environmental information.

For example, in a specific embodiment, the current ambient illuminance value can be obtained, and a preset illuminance value can be set. If the current ambient illuminance value is less than the preset illuminance value, it is determined that the infrared night vision device is in a working mode that needs to turn on the infrared light. The current ambient illuminance value is not less than the preset illuminance value, and it is determined that the infrared night vision device is in a working mode that does not need to turn on the infrared light.

Preferably, in order to avoid frequent switching of the working mode of the infrared night vision device, in another specific embodiment, a first preset illuminance value and a second preset illuminance value can be set, and the second preset illuminance value is greater than the first preset illuminance value. Set the illuminance value; no matter what working mode the infrared night vision device is currently in, if the current ambient illuminance value is less than the first preset illuminance value, it is determined that the infrared night vision device is in the working mode that needs to turn on the infrared light; if the current ambient illuminance value is greater than the first preset illuminance value Two preset illuminance values, determine that the infrared night vision device is in a working mode that does not need to turn on the infrared light; if the current ambient illuminance value is greater than or equal to the first preset illuminance value, and less than or equal to the second preset illuminance value, determine that the infrared night vision device It remains unchanged in the current working mode.

When the infrared night vision device is initially powered on and does not enter any working mode, the current ambient illuminance value can be compared with the first preset illuminance value. The first preset illuminance value enters the working mode that does not need to turn on the infrared lamp, and then controls the working mode according to the above-mentioned method. Of course, when the infrared night vision device is initially powered on and does not enter any working mode, the current ambient illuminance value can also be compared with the second preset illuminance value, and if it is greater than the second preset illuminance value, it will enter the work without turning on the infrared light Mode, if it is not greater than the second preset illuminance value, it will enter the working mode that needs to turn on the infrared lamp, and then control the working mode according to the above method. Of course, the operator can also pre-set the working mode when the infrared night vision device is initially powered on, and the infrared night vision device will directly enter the working mode after it is turned on, and then control the working mode according to the above-mentioned method.

The following is an example of comparing the current ambient illuminance value with the first preset illuminance value when the infrared night vision device is initially powered on, and illustrates the control method of the working mode of the infrared night vision device. The specific determination process is shown in Figure 6 , including the following steps:

Step 601 : When the infrared night vision device is initially powered on but does not enter any working mode, it is judged whether the current ambient illuminance value is less than the first preset illuminance value.

If the current ambient illuminance value is less than the first preset illuminance value, go to step 602;

If the current ambient illuminance value is not less than the first preset illuminance value, go to step 604 .

Step 602, the infrared night vision device enters into a working mode where the infrared lamp needs to be turned on.

At this time, the foregoing scheme can be adopted to control the working states of the multiple infrared lamps according to the current focusing distance of the infrared night vision device and the irradiation distance of the multiple infrared lamps in the infrared night vision device.

Step 603, judging whether the current ambient illuminance value is greater than a second preset illuminance value.

If the current ambient illuminance value is greater than the second preset illuminance value, go to step 604;

If the current ambient illuminance value is not greater than the second preset illuminance value, the infrared night vision device is still in the working mode that needs to turn on the infrared light, and this step 603 is executed in a loop.

Step 604, the infrared night vision device enters a working mode that does not need to turn on the infrared light.

At this time, all infrared controls are turned off.

Step 605, judging whether the current ambient illuminance value is smaller than a first preset illuminance value.

If the current ambient illuminance value is less than the first preset illuminance value, go to step 602;

If the current ambient illuminance value is not less than the first preset illuminance value, the infrared night vision device is still in the working mode that does not need to turn on the infrared light, and this step 605 is executed in a loop.

It can be seen that the control method of the infrared night vision device provided by the embodiment of the present invention can automatically judge whether the infrared night vision device needs to turn on the infrared light according to the current environment, and when the infrared light needs to be turned on, according to the current focusing distance of the infrared night vision device, Controlling the opening, closing and turning-on power of each infrared lamp avoids unnecessary opening and over-brightness of the infrared lamp, so it can further improve the invisible effect, and can greatly reduce the power loss of infrared night vision equipment, which is more energy-saving and economical.

Preferably, the control unit 702 is specifically configured to control the power of the turned-on infrared lamp according to the current focus distance; wherein, the smaller the current focus distance is, the smaller the power of the turned-on infrared lamp is.
