Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The temperature measuring method provided by the application can be applied to the application environment shown in FIG. 1. The object 100 to be measured is a person or other object that can emit an infrared signal, and the temperature measuring device 110 can be an infrared temperature measuring device that measures temperature by using infrared rays, such as an infrared thermometer or a thermal infrared imager. The broken line in the figure indicates infrared light.
In one embodiment, as shown in FIG. 2, a schematic flow diagram of a thermometry method is provided. The embodiment is mainly illustrated by applying the method to the temperature measuring device 110 in fig. 1.
The object to be measured in this embodiment takes a user as an example, and the body temperature of the user is measured by the temperature measurement device. The surface temperature is the temperature of the surface of the skin of the user, and the surface temperature of the user changes along with the change of the external temperature, for example, the surface temperature of the user is increased at high temperature, the surface temperature of the user is decreased at low temperature, and the corresponding surface temperatures of the skin at different positions are different even under the same environment, for example, the surface temperature of the forehead is usually higher than the surface temperature of the wrist. In one embodiment, the surface temperature of the user may be obtained by a thermometer in a manner that is highly accurate but time consuming, especially during the transmission of infectious diseases, which is susceptible to cross-contamination. In another embodiment, the surface temperature of the user can be obtained by an infrared thermometry device in a manner that does not require contact with the user's skin, is simple and convenient, is efficient, and reduces cross-contamination during the transmission of infectious diseases. In this embodiment, the surface temperature of the user is obtained by an infrared temperature measurement device.
The measurement location is a location on the user's body corresponding to the surface temperature, which may be, for example, the forehead, wrist, or torso, etc. In one embodiment, a camera may be installed in the infrared temperature measurement device, an image of a corresponding position is collected by the camera during temperature measurement, and a measurement position corresponding to the current surface temperature is determined by identifying the image collected by the camera. In another embodiment, a shift switch may be installed in the infrared temperature measurement device, different shift switches correspond to different measurement positions, and the measurement position is determined by reading the shift information of the shift switch. Of course, the present invention is not limited to the above two methods, and the measurement position may be determined in other methods.
And step 220, determining the current core temperature of the object to be measured according to the current surface temperature and the current measurement position in combination with the current environment temperature of the object to be measured.
Unlike the surface temperature, the core temperature is used to characterize the body temperature of the user, and is normally relatively stable. In one embodiment, the user's current core temperature may be determined from the surface temperature of the forehead and the current ambient temperature. In another embodiment, the current core temperature of the user may also be determined based on the surface temperature of the wrist and the current ambient temperature. In another embodiment, the current core temperature of the user may also be determined based on the surface temperature of the torso and the current ambient temperature.
Considering that the surface temperatures corresponding to different measurement positions are different, and the core temperature of the user is normally relatively stable, when the core temperature is determined based on the surface temperatures of the measurement positions such as the forehead, the wrist, or the torso, different temperature conversion coefficients can be set based on the different measurement positions. For example, the surface temperature of the wrist is low, and a high temperature conversion coefficient can be set; the surface temperature of the forehead is higher, and a lower temperature coefficient can be set; therefore, the core temperature obtained based on the forehead, the wrist or the trunk can be ensured to be the same, the influence of the measuring position on the core temperature is avoided, and the accuracy of the measuring result is improved. The temperature of the environment where the user is currently located can be inquired through networking by the infrared temperature measuring equipment, can also be input by the user, and can also be measured through the thermistor.
In another embodiment, the currently determined core temperature may be displayed after the core temperature is determined, and the specific display manner is not limited in this embodiment, and may be, for example, displayed by a digital tube, displayed directly by a character, or prompted by a voice broadcast manner.
According to the temperature measurement method, the core temperature of the object to be measured is determined by combining the current measurement position corresponding to the current surface temperature and the current environment temperature of the object to be measured on the basis of the current surface temperature of the object to be measured, so that the problem of poor measurement result accuracy caused by directly obtaining the surface temperature of the object to be measured in the prior art is effectively solved, and the accuracy of the measurement result is improved.
In another embodiment, as shown in FIG. 3, a flow diagram of a thermometry method is provided. The embodiment is mainly illustrated by applying the method to the temperature measuring device 110 in fig. 1.
And 310, determining the distance between the temperature measuring equipment and the object to be measured.
In one embodiment, the distance between the thermometric device and the object to be measured may be determined by a distance sensor. The distance sensor is used for transmitting ultrasonic waves, the ultrasonic waves return after encountering an object to be detected, and the distance between the temperature measuring equipment and the object to be detected can be determined by the temperature measuring equipment according to the sending and receiving time of the ultrasonic waves. For example, if the propagation speed of the ultrasonic wave is v, the transmission time of the ultrasonic wave is t1, and the reception time is t2, it can be determined that the distance from the object to be measured to the temperature measuring device is (t2-t1) × v/2. Considering that the ultrasonic wave attenuates along with the distance, in order to improve the accuracy of the measurement result, the distance between the object to be measured and the temperature measuring equipment is not too far, for example, a threshold value can be set, and when the distance between the object to be measured and the temperature measuring equipment is determined to be larger than the set threshold value, a user can be prompted to approach the temperature measuring equipment.
And 320, adjusting the focal length of an optical lens in the temperature measuring equipment according to the distance so that the infrared signal sent by the object to be measured is focused on an infrared temperature sensor in the temperature measuring equipment through the adjusted optical lens.
The optical lens is used for gathering infrared light emitted by the object to be measured on the infrared temperature sensor, so that the infrared temperature sensor determines the surface temperature of the object to be measured according to the gathered infrared light. In the traditional temperature measuring equipment, the focal length of an optical lens is fixed and does not change, and the focal length changes along with the measured distance when the optical lens is used for collecting infrared light energy radiated by an object to be measured, so that a measured distance error is introduced. In the embodiment, the optical lens with the variable focal length is adopted, and the focal length of the optical lens can be adjusted according to the distance between the object to be measured and the temperature measuring equipment. In one embodiment, the optical lens may be locked in the driving coil, and when the distance between the object to be measured and the temperature measuring device changes, the driving coil may be controlled to change the current in the temperature measuring device, so that the driving coil moves to drive the optical lens to move, thereby completing the focal length adjustment.
And step 330, reading the temperature of the infrared signal measured by the infrared temperature sensor as the current surface temperature of the object to be measured.
In one embodiment, the infrared temperature sensor can be an infrared thermopile infrared temperature sensor, and the sensor is internally provided with a Digital Signal Processor (DSP) and an infrared wavelength filter, so that the measurement precision is high. Of course, the present invention is not limited to this, and other types of infrared temperature sensors may be used, and the present embodiment is not limited thereto.
And 340, determining a current measurement position corresponding to the current surface temperature according to the current gear information of the multi-gear switch in the temperature measuring device.
In consideration of the fact that a camera is installed in the temperature measuring equipment, and the cost for determining the measuring position based on the image recognition mode is high, the embodiment takes a multi-gear switch as an example. Different gears in the multi-gear switch correspond to different measurement modes, for example, the multi-gear switch comprises three gears, namely an A gear, a B gear and a C gear, and can respectively correspond to three measurement modes of a wrist, a forehead and a trunk. The corresponding relation between the gears and the measuring modes can be stored in a gear information table in advance, the temperature measuring equipment can find the gear information table according to the current gear information of the multi-gear switch to determine the current measuring position, and the method is simple, convenient and low in cost. The gears corresponding to different measurement modes can be obtained by manually adjusting the multi-gear switch, for example, the current measurement mode is wrist, corresponding to the A gear, and when the measurement mode is forehead, the multi-gear switch can be switched from the A gear to the B gear.
And step 350, determining a corresponding temperature conversion coefficient according to the current measurement position.
Because the surface temperatures corresponding to different measuring positions are different, and the core temperature of the object to be measured is relatively stable under normal conditions, in order to ensure the reliability of the core temperature, different temperature conversion coefficients are set based on different measuring positions in the embodiment, so that the relatively stable core temperature can be obtained even if the measuring positions are different, and the reliability of the result is improved. The embodiment does not limit the determination process of the temperature conversion coefficient, for example, a model with the surface temperature and the measurement position as inputs and the core temperature as an output may be constructed, and the temperature conversion coefficients corresponding to different measurement positions may be obtained by training the model. And the temperature conversion coefficients corresponding to different measurement positions can be obtained by performing curve fitting on the surface temperature and the core temperature. In one embodiment, the forehead has a temperature transformation coefficient of 0.3094, the torso has a temperature transformation coefficient of 0.5067, and the wrist has a temperature transformation coefficient of 0.7665. In one embodiment, the measurement locations and corresponding temperature conversion coefficient associations may be stored to a temperature conversion coefficient table to facilitate subsequent lookup.
And step 360, determining the current core temperature of the object to be measured according to the current surface temperature and the temperature conversion coefficient corresponding to the current measurement position and by combining the current environment temperature of the object to be measured.
In one embodiment, the current core temperature of the object to be measured can be determined by the following formula:
T＝t+a*(t-t0)
wherein T is the current core temperature of the object to be measured, a is the temperature conversion coefficient corresponding to the current measurement position, T is the current surface temperature of the object to be measured, T is0The temperature of the environment where the object to be measured is located at present.
For a specific display mode, reference may be made to the above embodiments, which are not described herein again.
In one embodiment, as shown in fig. 4, a schematic flow chart of a method for measuring temperature is provided.
The object to be tested takes a user as an example:
determining the distance between a user and the temperature measuring equipment;
if the distance between the user and the temperature measuring equipment is larger than a set threshold value, prompting the user to approach the temperature measuring equipment;
if the distance between the user and the temperature measuring equipment is smaller than or equal to the set threshold, adjusting the focal length of the optical lens according to the distance, enabling infrared light radiated by the user to be focused on the infrared temperature sensor through the optical lens, and reading the measured value of the infrared temperature sensor to serve as the current surface temperature of the user;
searching a temperature conversion coefficient table according to the current gear information of the multi-gear switch, and determining a temperature conversion coefficient corresponding to the current measurement position;
