Description

Technical Field

[0001] This invention belongs to the field of temperature detection technology, and in particular relates to an ultra-low power wireless temperature detection probe suitable for polar environments. Background Technology

[0002] The polar regions are key and sensitive areas of the global climate system. Temperature changes in these regions are directly related to ice sheet melting, sea ice evolution, and sea level rise and fall, profoundly affecting the global climate pattern. Long-term polar temperature monitoring is the core basic data support for climate change research, environmental assessment, and scientific research support. Temperature detection probes are the core equipment for detecting polar environmental temperatures.

[0003] Currently, unmanned temperature monitoring in polar regions mainly uses platinum resistance temperature sensors as the core to build temperature probes. The equipment is powered by low-temperature batteries, and the collected temperature data can be stored locally or transmitted back via wireless links. It has been widely used for long-term observation in areas such as ice sheets, sea ice, and polar tundra. However, due to the complexity of the polar environment and the difficulty of energy replenishment, in order to control the overall power consumption and extend the battery life of the equipment, these probes generally adopt a fixed-interval timed sampling strategy. By reducing the number of collections and transmissions per unit time, the power consumption is reduced. Constrained by this mode, if the sampling frequency is maintained at a high level for a long time, the power consumption reduction effect will be poor. If the sampling interval is extended, the process of rapid temperature changes in the polar environment may be missed, resulting in untimely temperature measurement. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an ultra-low power wireless temperature detection probe suitable for polar environments that can minimize unnecessary temperature detection while ensuring timely sampling and thus reducing power consumption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ultra-low power wireless temperature detection probe suitable for polar environments, comprising a housing, a temperature measuring head, a microcontroller, and a battery. The microcontroller integrates a timing module and is fixed inside the housing. The temperature measuring head is fixed to the bottom of the housing and electrically connected to the microcontroller. The battery powers the microcontroller. The probe also includes: A mounting post is located below the battery. A connecting sleeve is fixed to the bottom of the mounting post, and a support post is fixed between the bottom of the connecting sleeve and the housing. Multiple strip-shaped ventilation holes are provided on the side wall of the connecting sleeve. The swing column is coaxially arranged inside the connecting sleeve, and multiple wind baffles are fixed on the side wall of the swing column. The swing column is equipped with a receiving mechanism. The pressure detection mechanism is installed inside the mounting column and connected to the swing column. The microcontroller controls the temperature measuring head and timing module to work according to the electrical signal fed back by the pressure detection mechanism. A wireless communicator is located above the battery and is connected to the microcontroller for communication.

[0006] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the receiving mechanism includes a cone block fixed to the bottom of a swing column. Multiple rotating rods are fixed to the side wall of the cone block. Multiple through holes are opened on the side wall of the connecting sleeve. The end of the rotating rod away from the cone block extends through the through hole to the outside of the connecting sleeve. An I-shaped sleeve is rotatably connected to the end of the rotating rod outside the connecting sleeve. Multiple annularly distributed baffles are fixed to the inner side of the I-shaped sleeve.

[0007] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the pressure detection mechanism includes a support ring. A circular groove is formed at the bottom of the mounting column, and the support ring is fixed inside the circular groove. A T-shaped column is coaxially arranged inside the circular groove, and the bottom of the T-shaped column is fixedly connected to the top of the swing column. Multiple evenly distributed pressure switches are fixed at the top of the support ring, and the moving contact of the pressure switch abuts against the bottom of the horizontal end of the T-shaped column. An analog switch is connected in series between the microcontroller and the detection circuit of the pressure switch. The microcontroller controls the temperature measuring head and timing module to work according to the electrical signal fed back by the pressure switch.

[0008] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, a support spring is fixed between the T-shaped column and the circular groove. The support spring is used to balance the gravitational force exerted on the pressure switch by the T-shaped column, the swing column, the wind deflector, and the receiving mechanism.

[0009] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the battery is fitted with an insulating shell, and the battery and the insulating shell are detachably connected. The mounting post is fixed to the bottom of the insulating shell, a top cover plate is fixed to the opening of the insulating shell, and an extension post is fixed to the top of the top cover plate. The wireless communicator is fixed to the top of the extension post, and the extension post and the insulating shell are jointly equipped with a heat transfer and heating unit.

[0010] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the heat transfer and heating unit includes a heat storage plate. A mounting groove is provided at the bottom of the top cover plate, and the heat storage plate is fixed at the opening of the mounting groove. An annular groove is provided at the top of the mounting groove, and multiple annularly distributed heat transfer rods are slidably inserted into the top of the annular groove. A heat insulation sleeve is fitted around the outside of each heat transfer rod, and the heat insulation sleeve is fixed to the top of the top cover plate. A heat-conducting ring is fixed to the top of the multiple heat insulation sleeves. A thermal expansion spring is fixed between the heat-conducting ring and the heat transfer rod. A flexible heat-conducting strip is fixed between the heat transfer rod and the heat-conducting ring. A heat collection mechanism is installed together with the extension column and the heat-conducting ring.

[0011] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the heat collection mechanism includes an upper mounting plate fixedly sleeved on the outside of the extension column, a lower mounting plate fixedly sleeved on the outer wall of the heat-conducting ring, and multiple condensing lenses fixed between the upper mounting plate and the lower mounting plate, with the multiple condensing lenses forming a frustum shape.

[0012] In the aforementioned ultra-low power wireless temperature detection probe suitable for polar environments, the outer side of the temperature measuring head is fitted with a conical shielding sleeve, and the side wall of the conical shielding sleeve has multiple annularly distributed air passage holes. The conical shielding sleeve can be detachably installed at the bottom of the housing.

[0013] Compared with existing technologies, the present invention has the following advantages: 1. This invention, through its housing, temperature sensor, microcontroller, battery, and timing module, enables the collection of polar environment temperatures via timed temperature detection, reducing power consumption. The mounting column, connecting sleeve, and support column separate the temperature sensor from the battery at both ends of the device, preventing the heat from the battery from affecting the accuracy of the temperature sensor. Furthermore, the inclusion of a strip-shaped ventilation hole, swing column, wind deflector, and pressure detection mechanism allows for automatic temperature collection when strong winds affect polar temperatures. This ensures timely temperature collection even when wind factors that influence polar temperatures are present, reducing the frequency of timed collection and further lowering power consumption. The pressure detection mechanism only requires power during normal operation when the moving contact is closed, eliminating the need for continuous power monitoring and resulting in low power consumption, which is beneficial for long-term monitoring in polar environments.

[0014] 2. The present invention, through the setting of the receiving mechanism, utilizes multiple baffles on the outside of the I-shaped sleeve to form multiple storage slots, thereby collecting rain, snow and ice particles. In conjunction with the cone block and the swing column, the gravity effect on the T-shaped column is increased, which can then be used in conjunction with the pressure switch to automatically trigger the temperature detection work. Combined with the factor of strong wind, it improves the timeliness of collecting data on factors affecting the temperature of the polar environment and ensures the timely response of temperature acquisition as much as possible.

[0015] 3. The present invention can reduce the impact of the external low temperature environment on the battery by setting the heat insulation shell, and improve the energy utilization rate of the battery. Secondly, by setting the top cover plate, extension column and heat transfer and heating unit, sunlight can be used to passively heat the battery, alleviate the problem of battery discharge performance degradation in polar and cold environments, and help extend the battery power supply time.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1-5As shown, an ultra-low power wireless temperature detection probe suitable for polar environments includes a housing 1, a temperature probe 2, a microcontroller 3, a battery 4, and a wireless communicator 14. The microcontroller 3 integrates a timing module 5 and is fixed inside the housing 1. The temperature probe 2 is fixed at the bottom of the housing 1 and electrically connected to the microcontroller 3. The battery 4 powers the microcontroller 3. The wireless communicator 14 is located above the battery 4 and communicates with the microcontroller 3. The temperature probe 2 uses a PT1000 platinum resistance probe, the wireless communicator 14 uses a LoRa wireless communication module, the microcontroller 3 uses a wide-temperature low-power microcontroller, the battery 4 uses a lithium thionyl chloride battery, and the timing module 5 uses a real-time clock module. The timing module 5 initially feeds back a timing signal to the microcontroller 3 every 2 hours. The interval can be preset by the microcontroller 3. The device also includes a mounting post 6 and a swing post 10.

[0020] Mounting post 6 is located below battery 4. A connecting sleeve 7 is fixed to the bottom of mounting post 6, and a support post 8 is fixed between the bottom of connecting sleeve 7 and box 1. Multiple strip-shaped ventilation holes 9 are opened on the side wall of connecting sleeve 7. Swing post 10 is coaxially located inside connecting sleeve 7, and multiple wind deflectors 11 are fixed on the side wall of swing post 10. The standard length of support post 8 is 1 meter, but it can also be set according to the requirements of the testing environment.

[0021] In practical use, this embodiment can collect the temperature of ice holes, snow, or seawater in polar environments by inserting the temperature sensor 2 into the ice hole, snow, or seawater. Since the microcontroller 3 and the temperature sensor 2 are on the same side, the wiring between them is short, thus minimizing the impact of wiring resistance on the detection accuracy of the temperature sensor 2. The battery 4 is located at the end furthest from the temperature sensor 2 via the housing 1, support column 8, connecting sleeve 7, and mounting column 6. Therefore, the temperature generated by the battery 4 is unlikely to affect the temperature sensor 2. Furthermore, the wireless communicator 14 is located at a high position, making it less susceptible to signal transmission obstruction by snow. Additionally, strong winds cause rapid alternation of hot and cold air, easily leading to… The temperature changes in the polar environment are aggravated. When strong winds occur in the polar environment, the wind flows through the strip ventilation hole 9 and the inside of the connecting sleeve 7. The wind force will generate a lateral thrust on the swing column 10 through the wind deflector 11. When this lateral thrust is detected, the microcontroller 3 starts the temperature measuring head 2 to immediately collect a temperature. This can capture key data on the sudden temperature change in windy weather. When the wind speed is lower than about 7 m / s, the temperature measuring head 2 can collect the temperature according to the timing information of the timing module 5. Only in windy weather can the temperature collection frequency be increased, which can reduce the overall average power consumption of the equipment. This can extend the working time of the equipment in the polar environment while ensuring the integrity of temperature monitoring.

[0022] like Figure 5 and Figure 6As shown, in this embodiment, the device further includes a pressure detection mechanism 13, which is installed inside the mounting column 6 and connected to the swing column 10. The microcontroller 3 controls the temperature measuring head 2 and the timing module 5 to work according to the electrical signal fed back by the pressure detection mechanism 13. The pressure detection mechanism 13 includes a support ring 131. A circular groove 132 is opened at the bottom of the mounting column 6, and the support ring 131 is fixed inside the circular groove 132. A T-shaped column 133 is coaxially arranged inside the circular groove 132, and the bottom of the T-shaped column 133 is fixedly connected to the top of the swing column 10. A plurality of annularly distributed pressure switches 134 are fixed at the top of the support ring 131, and the moving contact of the pressure switch 134 abuts against the bottom of the horizontal end of the T-shaped column 133. The microcontroller 3 controls the temperature measuring head 2 and the timing module 5 to work according to the electrical signal fed back by the pressure switch 134.

[0023] In actual testing, in this embodiment, when the swing column 10 is subjected to the lateral thrust of the wind, the swing column 10 will drive the T-shaped column 133 to deflect to one side. The horizontal part of the T-shaped column 133 abuts against the moving contact of the pressure switch 134. Therefore, when the T-shaped column 133 deflects to one side, the downward pressure on the pressure switch 134 on its horizontal end increases, thereby closing the moving contact of the pressure switch 134 and feeding back a closing electrical signal to the microcontroller 3. The microcontroller 3 will then immediately start the temperature measuring head 2 to collect a temperature once, and control the timing module 5 to shorten the timing interval to 30 minutes (this interval can be preset by the microcontroller 3). Since the moving contact of the pressure switch 134 is not closed during normal wind monitoring, no additional power consumption will be generated. Only after the moving contact of the pressure switch 134 is closed will the circuit between the pressure switch 134 and the microcontroller 3 be connected and consume a small amount of power. No power-on monitoring is required, resulting in low energy consumption. An analog switch 135 is provided between the pressure switch 134 and the IO detection terminal of the microcontroller 3. When the pressure switch 134 closes momentarily, it inputs a single-level trigger signal to the microcontroller 3. After the microcontroller 3 captures the trigger signal, it immediately controls the analog switch 135 to disconnect the detection circuit where the pressure switch 134 is located. Even if the pressure switch 134 remains closed, the circuit will no longer be conductive, thus avoiding the static leakage current power consumption caused by the long-term conduction of the series circuit between the pressure switch 134 and the microcontroller 3. After the timing module 5 reaches the timing node, the analog switch 135 returns to normal.

[0024] like Figure 6 As shown, in this embodiment, a support spring 15 is fixed between the T-shaped column 133 and the circular groove 132. The support spring 15 is used to balance the gravitational force of the T-shaped column 133, the swing column 10, the wind deflector 11 and the receiving mechanism 12 on the pressure switch 134.

[0025] In actual testing, in this embodiment, the T-shaped column 133 can be suspended by the support spring 15. The suspension force provided by the support spring 15 can balance the weight of the T-shaped column 133, the swing column 10, the wind deflector 11 and the receiving mechanism 12, so as to prevent the T-shaped column 133 from continuously pressing down on the pressure switch 134, so that the moving contact of the pressure switch 134 is in a closed state for a long time, which helps to improve the reliability of the pressure switch 134 in long-term operation.

[0026] like Figure 5 As shown, further, in this embodiment, the swing column 10 is equipped with a receiving mechanism 12. The receiving mechanism 12 includes a cone block 121 fixed to the bottom of the swing column 10. Multiple rotating rods 122 are fixed to the side wall of the cone block 121. Multiple through holes 123 are opened on the side wall of the connecting sleeve 7. The end of the rotating rod 122 away from the cone block 121 extends through the through hole 123 to the outside of the connecting sleeve 7. The end of the rotating rod 122 located outside the connecting sleeve 7 is rotatably connected to an I-shaped sleeve 124. Multiple annularly distributed baffles 125 are fixed on the inner side of the I-shaped sleeve 124. A damping sleeve is provided at the rotatable connection between the rotating rod 122 and the I-shaped sleeve 124 to prevent the I-shaped sleeve 124 from rotating arbitrarily.

[0027] In actual testing, in this embodiment, the inner side of the I-shaped sleeve 124 can be divided into multiple conical groove-shaped spaces by multiple baffles 125 on the inner side of the I-shaped sleeve 124. In rainy, snowy, or icy weather, rain, snow, and ice particles will fall into the groove-shaped spaces, thereby increasing the weight of the entire I-shaped sleeve 124. The T-shaped column 133 will also be affected by the increased weight, which will cause the moving contact of the pressure switch 134 to close and automatically trigger the temperature measurement program. When too much rain, snow, and ice particles are collected in the groove-shaped space at the top of the I-shaped sleeve 124, the I-shaped sleeve 124 will rotate downwards under the action of gravity because the distribution of rain, snow, and ice particles in the groove-shaped space at the top of the I-shaped sleeve 124 is not uniform. Subsequently, the rain, snow, and ice particles collected in the groove-shaped space will slide off, avoiding the long-term accumulation of rain, snow, and ice particles that will affect subsequent monitoring.

[0028] like Figure 4 As shown, in this embodiment, the battery 4 is further provided with an insulation shell 16 on its outer side, and the battery 4 and the insulation shell 16 are detachably connected. The mounting post 6 is fixed to the bottom of the insulation shell 16, the opening of the insulation shell 16 is fixed with a top cover plate 17, and the top of the top cover plate 17 is fixed with an extension post 18. The wireless communicator 14 is fixed to the top of the extension post 18.

[0029] In actual testing, in this embodiment, the heat dissipation rate of the battery 4 during operation can be reduced as much as possible through the heat insulation shell 16. Since the polar environment temperature is low, and low temperature will significantly reduce the discharge capacity and discharge efficiency of the battery 4, the heat insulation shell 16 can reduce the impact of external low temperature on the battery 4 to a certain extent and alleviate the performance degradation caused by low temperature.

[0030] like Figure 4 , Figure 8 and Figure 9 As shown, further, in this embodiment, the extension column 18 and the insulation shell 16 are jointly equipped with a heat transfer and heating unit 19. The heat transfer and heating unit 19 includes a heat storage plate 191. The bottom of the top cover plate 17 is provided with a mounting groove 192, and the heat storage plate 191 is fixed at the opening of the mounting groove 192. The top of the mounting groove 192 is provided with an annular groove 193, and a plurality of annularly distributed heat transfer rods 194 are slidably inserted into the top of the annular groove 193. The outer side of the heat transfer rods 194 is sleeved with a partition. A heat jacket 195 is fixed to the top of the top cover plate 17. A heat-conducting ring 196 is fixed to the top of multiple heat-conducting jackets 195. A thermal expansion spring 197 is fixed between the heat-conducting ring 196 and the heat transfer rod 194. A flexible heat-conducting strip 198 is fixed between the heat transfer rod 194 and the heat-conducting ring 196. A heat collection mechanism 20 is installed together with the extension column 18 and the heat-conducting ring 196. The heat storage plate 191 is made of heat storage ceramic material. The thermal expansion spring 197 is a bimetallic expansion spring.

[0031] In actual testing, when the external environment is low temperature, the heat transfer rod 194 does not contact the heat storage plate 191, and the air has a high thermal resistance. Therefore, the heat dissipated from the battery 4 to the outside through the heat transfer rod 194 can be minimized. When the external temperature rises, the thermal expansion spring 197 begins to extend, thereby pushing the heat transfer rod 194 to move and block the heat storage plate 191. The external heat will be conducted to the heat storage plate 191 and finally to the battery 4 through the heat storage plate 191, which can further reduce the impact of the external low temperature environment on the battery 4.

[0032] like Figure 4 As shown, further, in this embodiment, the heat collection mechanism 20 includes an upper mounting plate 201 fixedly sleeved on the outside of the extension column 18, a lower mounting plate 202 fixedly sleeved on the outer wall of the heat conducting ring 196, and a plurality of condensing lenses 203 fixed between the upper mounting plate 201 and the lower mounting plate 202, and the plurality of condensing lenses 203 together form a frustum shape, with an inclination angle of 75°-80° to the vertical direction. The condensing lenses 203 are Fresnel lenses, and their material is low-temperature resistant optical grade polycarbonate.

[0033] In actual testing, in this embodiment, the focusing lens 203 can concentrate sunlight and form multiple light spots on the upper surface of the heat-conducting ring 196, thereby heating the heat-conducting ring 196. The heat-conducting ring 196 can transfer heat to the heat storage plate 191 through the flexible heat-conducting strip 198 and the heat transfer rod 194, thereby helping to increase the temperature around the battery 4 when the sunlight is good.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, a conical shielding sleeve 21 is fitted on the outer side of the temperature measuring head 2, and a plurality of annularly distributed air passage holes 22 are opened on the side wall of the conical shielding sleeve 21. The conical shielding sleeve 21 can be detachably installed at the bottom of the box body 1.

[0035] In actual testing, in this embodiment, when it is necessary to insert the temperature measuring head 2 into ice holes, snow, or seawater, the conical shield 21 can be removed to avoid affecting the testing. However, when it is necessary to suspend the temperature measuring head 2 in the air to test the air temperature, the conical shield 21 can be installed. The conical shield 21 can reduce the influence of external sunlight and snow reflection on the temperature measuring head 2. Only the airflow passes through the air passage 22 to test the surrounding air temperature, making the test results more accurate.

[0036] The operation process of this invention is as follows: the entire device is fixed vertically and the temperature measuring head 2 is inserted into the ice hole, snow or seawater. During normal operation, when the timing module 5 reaches the preset collection interval, the microcontroller 3 will control the temperature measuring head 2 to collect the temperature once, and the microcontroller 3 will temporarily store the collected temperature data. After the stored temperature data reaches 12 times, the microcontroller 3 will package the data and send it to the receiving terminal in the polar scientific research station via the wireless communicator 14. When strong winds occur, the airflow passes through the strip ventilation hole 9 and the inside of the connecting sleeve 7. The wind force will generate a lateral thrust on the swing column 10 through the wind deflector 11. The swing column 10 will drive the T-shaped column 133 to deflect to one side. At this time, the downward pressure on the pressure switch 134 on the horizontal end of the T-shaped column 133 will increase, thereby closing the moving contact of the pressure switch 134 and feeding back the closing electrical signal to the microcontroller 3. The microcontroller 3 will then immediately start the temperature measuring head 2 to collect a temperature and control the timing module 5 to shorten the timing interval to the set value. If the closing electrical signal generated by the pressure switch 134 is disconnected during the next temperature measurement, the microcontroller 3 will control the timing module 5 to restore the timing interval to normal. Secondly, in rainy, snowy, or icy weather, the rain, snow, and ice particles will fall into the groove-shaped space formed by the I-shaped sleeve 124 and the baffle plate 125, increasing the weight of the entire I-shaped sleeve 124. At this time, through the rotating rod 122, the cone block 121, and the swing column 10, the T-shaped column 133 can be subjected to increased weight, thereby causing the T-shaped column 133 to press down on the pressure switch 134, causing the moving contact of the pressure switch 134 to close. Similarly, the microcontroller 3 will immediately start a temperature measurement program to improve the timeliness of the acquisition and response to changes in polar environmental temperature under windy, rainy, snowy, and icy weather.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
