Description

Technical Field

[0001] The utility model relates to the technical field of frostbite warning equipment, in particular to a frostbite warning device. Background Art

[0002] Frostbite is very likely to occur during combat, training and various types of military operations in cold areas. Frostbite is not only related to the ambient temperature, but also to the wind speed, that is, it is related to convective heat dissipation. For example, the ambient temperature of -30°C under breeze conditions is equivalent to the ambient cold intensity of -15°C under a wind speed of 6m / s. The wind-cooled temperature index can be calculated by measuring the wind speed and ambient temperature. In the prior art, the wind-cooled temperature is usually used as an indicator of the ambient cold intensity. The ambient cold intensity is graded according to whether the cold environment can cause frostbite in the human body and its speed, which is used to describe the impact of the cold environment on the body. The ambient cold intensity is divided into 4 levels, namely, a cold environment without frostbite, a mild frostbite environment, a moderate frostbite environment and an extreme frostbite environment. Among them, in a non-frostbite cold environment, the risk of frostbite is low, and frostbite is possible but not certain to occur; in a mildly frostbite-causing environment, the risk of frostbite is high, and frostbite may occur within 10 to 30 minutes of cold exposure; in a moderately frostbite-causing environment, the risk of frostbite is very high, and frostbite may occur within 5 to 10 minutes of cold exposure; in an extremely frostbite-causing environment, the risk of frostbite is extremely high, and frostbite may occur within 5 minutes of cold exposure.

[0003] At present, there is no dedicated frostbite warning instrument, and other devices that measure temperature and wind speed are based on ambient temperature and ignore the impact of wind speed on frostbite. In addition, since electronic monitoring equipment is used in cold environments, there is a reduction in sensitivity, which leads to deviations in the test results.

[0004] Therefore, the above-mentioned technical problems need to be further solved. Summary of the invention

[0005] The purpose of the embodiment of the utility model is to provide a frostbite warning device, so as to obtain the environmental cold intensity value and the environmental cold intensity level based on the wind speed information and the environmental temperature information at the same time.

[0021] a third heating device, disposed on the wind speed sensor near the rotating frame, and electrically connected to the wind speed sensor and the battery respectively;

[0047] The utility model provides a frostbite warning device, such as Figure 1 As shown, the frostbite warning device includes a first frame 1 and a second frame 2 connected to the first frame 1, a wind speed detection assembly 7 connected to the second frame 2 is arranged in the first frame 1, and a switch key 21 and a display screen 23 are arranged on the outer surface of the second frame 2. A plurality of first prompting members 14 are arranged on the first frame 1, and a second sensor 15 for obtaining ambient temperature information is arranged at the end of the first frame 1 away from the second frame 2. A first space 6 and a second space 4 are arranged in the second frame 2, a single-chip microcomputer 61 is connected in the first space 6, a battery 41 is placed in the second space 4, a first sensor 62 for obtaining temperature information of the single-chip microcomputer 61 and a first heating device 63 for heating the first space 6 are also arranged in the first space 6, and a second heating device 5 for heating the display screen 23 is arranged on the surface of the display screen 23 near the second space 4. A second prompting member 24 and a third sensor 3 for obtaining temperature information of the display screen 23 are arranged on the surface of the second frame 2.

[0048] In this embodiment, the wind speed detection component 7 obtains wind speed information in the first frame 1, and the single chip 61 simultaneously calculates the wind speed information and the ambient temperature information obtained by the second sensor 15 to obtain the ambient cold intensity value, and obtains the ambient cold intensity level according to the ambient cold intensity value, and the first prompting member 14 presents a warning of the target color according to different ambient cold intensity levels, and the second prompting member 24 emits a buzzing sound of the target rate according to different ambient cold intensity levels. Thus, the frostbite warning device can obtain the ambient cold intensity value and the ambient cold intensity level based on the wind speed information and the ambient temperature information at the same time, avoiding deviations in the detection results.

[0049] When the temperature in the first space 6 is lower than the target temperature, the single chip 61 controls the first heating device 63 to turn on and heat, and the first heating device 63 heats up to the target temperature in the first space 6 to keep the single chip 61 warm; when the temperature of the display screen 23 is lower than the target temperature, the single chip 61 controls the second heating device 5 to turn on and heat, and the second heating device 5 heats up to the target temperature to keep the display screen 23 warm. Therefore, when the frostbite warning device is used in a cold environment, there is no reduction in sensitivity, which avoids deviations in the detection results.

[0050] In a specific embodiment, Figure 1 As shown, the first frame 1 includes a first arc-shaped member 11, a second arc-shaped member 12 and a third space 13. The first arc-shaped member 11 is connected to the second frame 2. The second arc-shaped member 12 is arranged in parallel with the first arc-shaped member 11, close to the side of the wind speed detection component 7, and connected to the second frame 2. A closed third space 13 is formed between the first arc-shaped member 11, the second arc-shaped member 12 and the second frame 2. Among them, the first prompt member 14 is arranged on the outer surface of the third space 13 and is electrically connected to the single-chip computer 61.

[0051] In this embodiment, the first frame 1 and the second frame 2 block the wind in the external environment from blowing toward the wind speed detection component 7 from the side of the wind speed detection component 7. In other words, when it is necessary to detect the wind speed and ambient temperature in the target direction, it is only necessary to turn the front of the wind speed detection component 7 toward the target direction for detection. This improves the accuracy of the detection result.

[0052] More specifically, the third space 13 provides enhanced insulation against the wind and temperature on the side of the wind speed detection component 7 to avoid affecting the detection results of the wind speed and ambient temperature in the target direction.

[0053] In a specific embodiment, Figure 2As shown, the wind speed detection assembly 7 includes a fan blade 71, a rotating frame 72, a wind speed sensor, a fourth sensor 74, a third heating device 73 and a connecting rod 75. The rotating frame 72 is connected to the fan blade 71. The wind speed sensor is arranged on the rotating frame 72, and its signal is connected to the single-chip microcomputer 61. The fourth sensor 74 is arranged on the wind speed sensor near the side of the rotating frame 72, and its signal is connected to the wind speed sensor and the single-chip microcomputer 61 at the same time. The third heating device 73 is arranged on the wind speed sensor near the side of the rotating frame 72, and is electrically connected to the wind speed sensor and the battery 41 respectively. The connecting rod 75 is connected to the rotating frame 72 and the second frame 2 at the same time.

[0054] In this embodiment, the fan blades 71 rotate with the wind to drive the rotating frame 72 to rotate, the wind speed sensor obtains the wind speed information in the target direction, and transmits the wind speed information to the single chip 61, so that the single chip 61 calculates the wind speed information and the ambient temperature information at the same time to obtain the ambient cold intensity value, and obtains the ambient cold intensity level according to the ambient cold intensity value. Among them, the process of calculating the ambient cold intensity value and obtaining the ambient cold intensity level according to the ambient cold intensity value adopts the existing technology, which is a mature solution and does not belong to the focus of the utility model, so it is not described in detail.

[0055] When the fourth sensor 74 obtains that the temperature of the wind speed sensor is lower than the target temperature, the battery 41 provides power to the third heating device 73, so that the third heating device 73 heats the wind speed sensor to the target temperature. Thus, the wind speed sensor is at the target temperature to avoid affecting the detection result of the wind speed in the target direction.

[0056] In a specific embodiment, the single chip microcomputer 61 is respectively connected to the first sensor 62, the second sensor 15, the third sensor 3, the first heating device 63, the second heating device 5, the third heating device 73, the first prompting member 14 and the second prompting member 24.

[0057] In this embodiment, the single-chip computer 61 uses very large-scale integrated circuit technology to integrate a central processing unit, random access memory, read-only memory, multiple I / O ports and interrupt systems, timers / counters, as well as display drive circuits, pulse width modulation circuits, analog multiplexers, A / D converters and other circuits to form a microcomputer system.

[0058] In a specific embodiment, the first heating device 63 is electrically connected to the battery 41. The battery 41 is also electrically connected to the single chip computer 61, the first prompting member 14, the second prompting member 24, the display screen 23 and the switch key 21 respectively.

[0059] The display screen 23 displays the ambient cold intensity value and / or the ambient cold intensity level according to actual application requirements.

[0060] A fourth heating device is provided in the second space 4 where the battery 41 is located, and the fourth heating device heats the battery 41 in the second space 4 to a target temperature so as to maintain the target temperature, thereby enabling the battery 41 to output electrical energy stably, further improving the stability of the detection result.

[0061] A charger is connected next to the battery 41, so that the battery 41 can be charged during the power-on process via an external charging cable in the prior art.

[0062] In the present invention, the first heating device 63, the second heating device 5, the third heating device 73 and the fourth heating device may be heating resistors, or other structures or devices capable of achieving heating in the prior art.

[0063] In order to prevent the staff from blocking the second prompt member 24 with their hands during the detection process and thus affecting the warning of the second prompt member 24, in a specific embodiment, as shown in FIG. Figure 1 As shown, the second prompting member 24 is a buzzer, which is arranged on the surface of the second frame 2 between the display screen 23 and the first space 6. A fourth space for placing the buzzer is arranged in the second frame 2.

[0064] In a specific embodiment, the buzzer is electrically connected to the battery 41 , and the buzzer signal is connected to the single chip microcomputer 61 .

[0065] In a specific embodiment, Figure 1 As shown, a first passage 8 for wind to blow through is formed between the surface of the second arc-shaped member 12 near the fan blade 71 and the second frame 2. The fan blade 71 is located in the first passage 8.

[0066] In this embodiment, the fan blades 71 are located at the center of the first channel 8. When wind passes through the first channel 8, the fan blades 71 can be driven to rotate more evenly, thereby improving the accuracy of the wind speed information in the target direction obtained by the wind speed sensor.

[0067] Since the second sensor 15 is located at the end of the first frame 1 away from the second frame 2 , which is adjacent to the first channel 8 , it is convenient to collect the external environment temperature information at the first channel 8 more accurately.

[0068] In the utility model, the cold intensity of the environment is divided into four levels in the prior art, specifically, a non-freezing cold environment, a mild freezing environment, a moderate freezing environment, and an extreme freezing environment. Among them, a non-freezing cold environment has a low risk of freezing, and there is a possibility of freezing, but not necessarily freezing; a mild freezing environment has a high risk of freezing, and freezing may occur within 10 to 30 minutes of cold exposure; a moderate freezing environment has a high risk of freezing, and freezing may occur within 5 to 10 minutes of cold exposure; an extreme freezing environment has a very high risk of freezing, and freezing may occur within 5 minutes of cold exposure.

[0069] The first prompting member 14 presents target colors according to different levels of environmental cold intensity, which are green, blue, orange, and red warning light strips, respectively. The second prompting member 24 emits a buzzing alarm sound ranging from slow to fast according to different levels of environmental cold intensity. Among them, the early warning system of the first prompting member 14 and the second prompting member 24 adopts the existing technology. Since it is a mature technical solution and does not belong to the focus of the utility model, it will not be described in detail.

[0070] In the present invention, the specific quantity of any sensor among the wind speed sensor, the first sensor 62, the second sensor 15 and the third sensor 3 can be adjusted according to different application requirements.

[0071] When the specific number of any of the wind speed sensor, the first sensor 62, the second sensor 15 and the third sensor 3 is greater than or equal to 2, the single chip computer 61 will calculate the average value of the information obtained by the multiple sensors, thereby further avoiding deviations in the detection results.

[0072] According to different application requirements, an anti-slip member 22 is further provided at the bottom of the second frame 2, so that the staff can hold the frostbite warning device more stably.

[0073] The utility model measures the ambient temperature information and wind speed information, calculates the wind-cooling temperature index, and accurately predicts the risk of frostbite in the environment. By detecting the wind speed information, the convective heat dissipation effect of the wind speed can also be applied to the frostbite warning. By setting multiple sensors to obtain the ambient temperature information, wind speed information, single-chip computer 61 temperature information, display screen 23 temperature information, etc., the ambient temperature is comprehensively assessed, which is beneficial to the accuracy of the detection result. By setting a four-level frostbite warning alarm, it is beneficial to scientifically and accurately predict the risk of frostbite. By setting a first prompting piece 14 and a second prompting piece 24 with multiple forms of alarm prompts, negligence of the operator is avoided, which is conducive to taking protective measures in time. By setting multiple heating devices, it is ensured that each component can work under normal temperature conditions, and the deviation of the detection result caused by the low temperature of the environment is avoided.

[0074] The utility model can provide a convenient warning tool for early warning of frostbite for military operations and other outdoor workers in cold regions. The cold region in the utility model refers to a region or climate with a temperature below 0°C.

[0075] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
