Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.

In practical application, when an operator uses the thermal imager, the screen of the thermal imager can be lightened, and when the operator does not need to use the thermal imager temporarily, the screen of the thermal imager needs to be manually closed. Furthermore, when the screen of the thermal imager is in a lit state, when the operator does not need to use the thermal imager for a while and cannot close the screen of the thermal imager, the screen of the thermal imager will be in a lit state all the time, thereby causing waste of energy consumption of the thermal imager.

In order to solve the technical problem, an embodiment of the invention provides a screen control method.

The method can be applied to any application scene in which the screen of the thermal imager needs to be closed in time when the thermal imager is in a vertical state unused by an operator, and can be applied to any electronic equipment capable of closing and lighting the screen of the thermal imager, for example, the method can be applied to the thermal imager and can also be applied to control end equipment of the thermal imager. This is all reasonable. That is to say, the application scenario and the execution subject of the method are not limited in the embodiment of the present invention.

The screen control method provided by the embodiment of the invention can comprise the following steps:

Therefore, by applying the scheme provided by the embodiment of the invention, the pitch angle of the thermal imager can be acquired when the screen of the thermal imager is in a lighting state, and then, if the acquired pitch angle corresponds to the vertical state of the thermal imager, the thermal imager is not used by an operator in the vertical state, so that the screen of the thermal imager can be closed.

Based on this, when the screen of the thermal imager is in a lighting state, the screen of the thermal imager can be closed in time by acquiring the pitch angle of the thermal imager when the thermal imager is in a vertical state unused by an operator, and the problem of energy consumption waste caused by the fact that the screen of the thermal imager is always in the lighting state is solved.

Before describing a screen control method provided by an embodiment of the present invention in detail, a pitch angle involved in the method will be described first.

Since the thermal imager is usually hung by the operator on the neck of the operator through a hanging rope, the rotation angle of the thermal imager on the vertical plane with the head of the operator as the rotation point may be referred to as the pitch angle of the thermal imager.

For example, taking a handheld thermal imager as an example, as shown in fig. 1(a), a two-dimensional coordinate system is established with the head of an operator as an origin, the upward vertical direction in a vertical plane as a negative direction of a longitudinal axis, the downward vertical direction in the vertical plane as a positive direction of the longitudinal axis, and the horizontal sight direction of the operator as a positive direction of a transverse axis, and then angles α, β, and γ in fig. 1(a) are angle ranges in which the pitch angles of the handheld thermal imager are in different states, respectively.

As shown in fig. 1(b), when the operator uses the handheld thermal imager, the operator can usually hold the handheld thermal imager and horizontally place the handheld thermal imager in front of the eyes of the operator, and the handheld thermal imager can be vertically shaken for observation in the process of using the handheld thermal imager, so that the angle range α in fig. 1(a) can be the angle range where the pitch angle of the handheld thermal imager is located when the handheld thermal imager is in a use state, and at this time, the pitch angle of the thermal imager can be considered to correspond to the horizontal state of the thermal imager; correspondingly, as shown in fig. 1(c), when the operator does not need to use the handheld thermal imager temporarily, the handheld thermal imager may be directly suspended in front of the chest of the operator, and at this time, the handheld thermal imager is in a vertical state, and when the handheld thermal imager is in the vertical state, the handheld thermal imager may shake along with the movement of the operator, for example, shake along with the walking of the operator, so the angle range β in fig. 1(a) may be an angle range where the pitch angle of the handheld thermal imager is located when the handheld thermal imager is in an unused state, and at this time, the pitch angle of the thermal imager may be considered to correspond to the vertical state of the thermal imager.

Hereinafter, a screen control method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a screen control method according to an embodiment of the present invention, and as shown in fig. 2, the method may include the following steps S201 to S202:

s201: acquiring a pitch angle of the thermal imager when a screen of the thermal imager is in a lighting state;

in the using process of the thermal imager, an operator may first initialize the thermal imager, for example, adjust a focal length of the thermal imager, select a temperature measuring range of the thermal imager, and after the initialization is completed, may light a screen of the thermal imager. In this way, the operator can begin using the thermal imager.

Based on this, in order to avoid the situation that the operator is exposed due to the lighted screen of the thermal imager, the pitch angle of the thermal imager may be acquired while the screen of the thermal imager is in a lighted state.

The thermal imager can be provided with a motion device with a pitch angle detection function, so that the motion module is used for detecting the pitch angle of the thermal imager. For example, it is reasonable to detect the pitch angle of the thermal imager, etc., using a gravity sensor installed in the thermal imager. The embodiment of the invention does not limit the method for acquiring the pitch angle of the thermal imager and the used acquisition device.

Optionally, when the screen control method provided by the embodiment of the invention is applied to a thermal imager, the thermal imager can directly detect the own pitch angle by using a motion device with a pitch angle detection function installed on the thermal imager when the screen of the thermal imager is in a lighted state.

Optionally, when the screen control method provided by the embodiment of the invention is applied to a control end device of a thermal imager, the thermal imager can directly detect the pitch angle of the thermal imager by using a motion device with a pitch angle detection function installed on the thermal imager when the screen of the thermal imager is in a lighted state, and send the detected pitch angle to the control end device.

Optionally, the pitch angle of the thermal imager can be acquired in real time when the screen of the thermal imager is in a lighting state.

Optionally, when the screen of the thermal imager is in a lighting state, the pitch angle of the thermal imager can be obtained according to a preset angle detection frequency.

Optionally, in a specific implementation manner, the thermal imager may be a handheld thermal imager, and then the thermal imager may be suspended on the front side of the body of the operator through a hanging rope.

S202: if the pitch angle corresponds to the vertical state of the thermal imager, closing the screen of the thermal imager;

wherein the thermal imager is not used by an operator in a vertical state.

When the screen of the thermal imager is in a lighting state, when the pitch angle of the thermal imager is obtained, the state of the thermal imager can be determined according to the obtained pitch angle. The thermal imager is not used by an operator in a vertical state, so that if the acquired pitch angle corresponds to the vertical state of the thermal imager, that is, the thermal imager can be determined to be in the vertical state according to the acquired pitch angle, the thermal imager can be determined not to be used by the operator, and then the screen of the thermal imager can be closed.

For example, as shown in fig. 1(c), when the screen of the thermal imager is in a lit state, if it is determined that the thermal imager is in a vertical state according to the acquired pitch angle, the screen of the thermal imager may be turned off.

In step S202, although the screen of the thermal imager is turned off, the thermal imager is not turned off. That is, in the step S202, after the screen of the thermal imager is turned off, the thermal imager may enter the standby mode in the screen-off state instead of directly turning off the thermal imager. Thus, when the operator uses the thermal imager again, the screen of the thermal imager only needs to be lit again, and the thermal imager does not need to be restarted.

Based on this, optionally, in a specific implementation manner, the screen control method according to the embodiment of the present invention may further include the following step a.

Step A: after closing the screen of the thermal imager, if the pitch angle of the thermal imager corresponds to the horizontal state of the thermal imager, lighting the screen of the thermal imager;

wherein the thermal imager is used by an operator in a horizontal state.

In this specific implementation manner, after the step S202 is executed and the screen of the thermal imager is closed, the pitch angle of the thermal imager may be continuously obtained, and the state of the thermal imager may be determined according to the obtained pitch angle. The thermal imager is used by the operating philosophy in the horizontal state, so that if the acquired pitch angle corresponds to the horizontal state of the thermal imager, namely the thermal imager can be determined to be in the horizontal state according to the acquired pitch angle, the thermal imager can be determined to be used by an operator, and then the screen of the thermal imager can be lightened.

For example, as shown in fig. 1(b), after the step S202 is executed and the screen of the thermal imager is closed, if the continuously acquired pitch angle of the thermal imager corresponds to the horizontal state of the thermal imager, the screen of the thermal imager may be turned on again.

As can be seen from the above, by applying the scheme provided by the embodiment of the invention, when the screen of the thermal imager is in the lit state, the screen of the thermal imager can be timely turned off by acquiring the pitch angle of the thermal imager when the thermal imager is in the vertical state unused by the operator, so that the problem of energy consumption waste caused by the fact that the screen of the thermal imager is always in the lit state is solved.

Furthermore, the screen of the thermal imager is typically disposed near an end of the eyes of the operator during use, for example, as shown in fig. 1(b), the screen of the thermal imager is disposed near an end of the eyes of the operator, as shown in fig. 1(c), and the screen of the thermal imager is disposed at an upper end of the thermal imager.

In the using process of the thermal imager, after the thermal imager is started, the initialization menu can be displayed on the screen, so that an operator can complete initialization of the thermal imager through operation of the menu on the screen of the thermal imager, for example, selection of a working mode of the thermal imager and the like. Furthermore, after the screen of the thermal imager is lightened, an operator can observe a scene in a view field range corresponding to the pitch angle of the thermal imager through the screen of the thermal imager.

Among other things, thermal imagers are typically hung by an operator from the neck of the operator via a lanyard for ease of carrying and to prevent loss. Thus, when the operator hangs the thermal imager around the neck without using the thermal imager for a while, the thermal imager assumes the posture shown in fig. 1(c) in front of the operator with the screen of the thermal imager positioned above. Thus, since the screen of the thermal imager is in an illuminated state, the light emitted by the screen of the thermal imager will illuminate the upper body of the operator, thereby exposing the operator.

Based on the technical scheme, the problem that an operator is exposed due to the fact that the screen of the thermal imager is lightened can be solved, and the use efficiency of the thermal imager is improved.

Optionally, in a specific implementation manner, as shown in fig. 3, in the step S202, if the pitch angle corresponds to the vertical state of the thermal imager, the closing the screen of the thermal imager may include the following steps S2021 to S2022:

s2021: if the pitch angle belongs to a preset target range, determining that the pitch angle corresponds to the vertical state of the thermal imager;

s2022: and closing the screen of the thermal imager.

In this specific implementation manner, when the screen of the thermal imager is in a lit state, when the pitch angle of the thermal imager is obtained, the numerical relationship between the obtained pitch angle and the preset target range may be determined, and then, if the obtained pitch angle belongs to the preset target range, it may be determined that the obtained pitch angle corresponds to the vertical state of the thermal imager, so that the screen of the thermal imager may be turned off.

The target range can be determined according to the actual use condition of the thermal imager, and the pitch angle of the thermal imager is within the angle range when the thermal imager is not used by an operator.

For example, as shown in fig. 1(a), the preset target range may be an angle range β.

Therefore, when the preset target range is the angle range where the pitch angle of the thermal imager is located when the thermal imager is not used by an operator, the thermal imager can be determined to be in a vertical state when the acquired pitch angle belongs to the preset target range, and therefore the thermal imager can be determined not to be used by the operator, and then the screen of the thermal imager can be closed.

In practical application, in the process that the thermal imager is used by an operator, the operator can shake the thermal imager up and down by a large margin in a vertical plane under certain conditions.

For example, a thermal imager is used to view the found object from top to bottom and from bottom to top. Thus, at some point in time, it may occur that the thermal imager is being used by an operator although the pitch angle of the thermal imager falls within the above-described preset target range.

Based on this, optionally, in a specific implementation manner, in the step S2021, if the pitch angle belongs to the preset target range, determining that the pitch angle corresponds to the vertical state of the thermal imager may include the following step B.

And B: and if all the pitch angles acquired within the preset judgment time length belong to the preset target range, determining that all the acquired pitch angles correspond to the vertical state of the thermal imager.

In the specific implementation manner, when the screen of the thermal imager is in a lighting state, a plurality of pitch angles of the thermal imager within a preset determination time period can be continuously acquired, and after each pitch angle of the thermal imager is acquired, the numerical relationship between the pitch angle and a preset target range is determined. Furthermore, if each pitch angle acquired within the preset determination time period belongs to the preset target range, it may be determined that each acquired pitch angle corresponds to the vertical state of the thermal imager, that is, it may be determined that the thermal imager is in the vertical state within the preset determination time period, and thus it may be determined that the thermal imager is not used by an operator within the preset determination time period.

Therefore, when an operator uses the thermal imager, the thermal imager is greatly shaken up and down in a vertical plane, so that at some moments, when the pitch angle of the thermal imager belongs to the preset target range, the misjudgment on the state of the thermal imager can be avoided, and further, the condition that the screen of the thermal imager is closed when the thermal imager is used by the operator is avoided, and the use of the operator on the thermal imager is influenced.

Further, in an actual use situation, the thermal imager may be fixed at a certain pitch angle, and a view field corresponding to the pitch angle is continuously observed. In the above case, if the pitch angle of the thermal imager is fixed and the pitch angle of the thermal imager belongs to the preset target range, the pitch angles of the thermal imagers all belong to the preset target range for a long period of time, however, during this period of time, although the pitch angle of the thermal imager belongs to the preset target range, the thermal imager is being used by an operator.

For example, if the operator uses the thermal imager to continuously observe a target on the ground, the pitch angle of the thermal imager falls within the preset target range for a period of time, but the thermal imager is being used by the operator during the period of time.

Correspondingly, when the thermal imager is in a vertical state due to non-use by an operator, the thermal imager can shake along with the action of the operator, so that the pitch angle of the thermal imager changes, namely, when the thermal imager is in the vertical state due to non-use by the operator, the pitch angle of the thermal imager cannot be fixed and unchanged.

For example, as shown in fig. 1(a), the thermal imager may shake as the operator moves, so that the pitch angle of the thermal imager may vary within an angle range β, and the angle range β may be a preset target range.

Based on this, optionally, in a specific implementation manner, in the step S2021, if the pitch angle belongs to the preset target range, determining that the pitch angle corresponds to the vertical state of the thermal imager may include the following step C.

And C: and if all the pitch angles acquired within the preset judgment time length belong to the preset target range and are not completely the same, determining that each pitch angle corresponds to the vertical state of the thermal imager.

In the specific implementation manner, when the screen of the thermal imager is in a lighting state, a plurality of pitch angles of the thermal imager within a preset determination time period can be continuously acquired, after each pitch angle of the thermal imager is acquired, the numerical relationship between the pitch angle and a preset target range is determined, and then whether each pitch angle is the same or not is determined according to the variation condition of each acquired pitch angle. Furthermore, if the obtained pitch angles all belong to the preset target range within the preset determination time period and are not completely the same, it can be determined that the obtained pitch angles correspond to the vertical state of the thermal imager, that is, it can be determined that the thermal imager is in the vertical state within the preset determination time period, and the pitch angles of the thermal imager are not fixed within the preset determination time period, so that it can be determined that the thermal imager is not used by an operator within the preset determination time period.

Therefore, when an operator uses the thermal imager, the pitch angle of the thermal imager is fixed at an angle within a certain preset target range, so that the misjudgment of the state of the thermal imager can be avoided when the view field range corresponding to the pitch angle is continuously observed, and further, the condition that the screen of the thermal imager is closed when the thermal imager is used by the operator is avoided, and the use of the operator on the thermal imager is influenced.

Optionally, in a specific implementation manner, in the step C, if each pitch angle acquired within a preset determination duration belongs to a preset target range and each pitch angle is not completely the same, determining that each pitch angle corresponds to the vertical state of the thermal imager may include the following steps C1 to C2.

Step C1: determining the numerical relationship between each pitch angle acquired in the preset judging time and a preset target range; calculating the change rate of the pitch angle acquired in each unit duration of the judgment duration;

step C2: if each pitch angle belongs to the target range and each calculated change rate meets a preset judgment condition, determining that each pitch angle corresponds to the vertical state of the thermal imager;

wherein, each calculated change rate accords with a preset judgment condition for indicating that the obtained pitch angles are not completely the same, and the preset judgment condition comprises: there is a rate of change that is not zero, or each rate of change is not zero.

In this specific implementation manner, when the screen of the thermal imager is in a lit state, a plurality of pitch angles of the thermal imager within a preset determination time period may be continuously acquired. Further, the numerical relationship between the pitch angle and the preset target range can be determined, and the change rate of the acquired pitch angle in each unit time length of the preset determination time length is calculated. Wherein the unit time length is not greater than the preset judgment time length.

Furthermore, the calculated change rates meet the preset judgment condition and can be used for indicating that the acquired pitch angles are not completely the same, so that if the pitch angles all belong to the target range and the calculated change rates meet the preset judgment condition, the acquired pitch angles can be determined to correspond to the vertical state of the thermal imager, that is, the thermal imager can be determined to be in the vertical state within the preset judgment duration, and the pitch angles of the thermal imager are not fixed and unchanged within the preset judgment duration, so that the thermal imager can be determined to be unused by an operator within the preset judgment duration.

Wherein the preset judgment condition comprises: if the pitch angles belong to the target range and the calculated change rates are not zero, determining that the acquired pitch angles correspond to the vertical state of the thermal imager; or if each pitch angle belongs to the target range and each calculated change rate is not zero, it may be determined that each acquired pitch angle corresponds to the vertical state of the thermal imager.

Optionally, for each unit duration of the preset determination duration, the pitch angle obtained at the start time of the unit duration and the pitch angle obtained at the end time of the unit duration may be determined first, and then the difference between the two obtained pitch angles may be calculated. Then, the ratio of the difference to the unit time length can be calculated, and the calculated ratio is the change rate of the pitch angle acquired in the unit time length.

Optionally, for each unit duration of the preset determination duration, a maximum value and a minimum value of the pitch angles acquired in the unit duration may be determined first, and then a difference between the determined maximum value and the determined minimum value is calculated, so that the difference is used as a change rate of the pitch angle acquired in the unit duration.

Thermal imagers may typically have a variety of operating modes, for example, an operating mode that continues to be in use at a fixed pitch angle; for example, the operating mode is switched between the used state and the unused state according to the state of the thermal imager corresponding to the pitch angle.

In some working modes, the thermal imager needs to be continuously in a used state no matter what state the pitch angle of the thermal imager corresponds to, so that in the working modes, the screen of the thermal imager is in a lighted state, and even if the thermal imager is in a vertical state, the screen of the thermal imager still does not need to be closed; and in other working modes, when the screen of the thermal imager is in a lighting state, whether the thermal imager is in a used state or not can be determined according to the pitch angle of the thermal imager, and when the thermal imager is not in the used state, the screen of the thermal imager is closed.

Based on this, optionally, in a specific implementation manner, as shown in fig. 4, the screen control method provided in the embodiment of the present invention may further include the following step S200:

s200: and controlling the thermal imager to enter a specified working mode, and lighting a screen of the thermal imager.

In this specific implementation manner, before the screen of the thermal imager is lit, the thermal imager may be first controlled to enter a specified operating mode, and then the screen of the thermal imager is lit.
