Description

Technical Field

[0001] The invention relates to the technical field of remote sensing monitoring devices for temperature changes, and in particular to a remote sensing monitoring device for temperature changes in a wheat field. Background Art

[0002] Wheat fields refer to farmland specifically used for growing crops such as wheat and barley. Temperature changes in wheat fields are usually monitored using remote sensing technology. Sensors mounted on support platforms are mainly used to conduct long-distance observations of the surface. These sensors can capture electromagnetic wave information reflected or emitted by the surface, and extract the required temperature change information through data processing and analysis.

[0003] When the existing remote sensing monitoring devices for temperature changes in wheat fields are used, most of the temperature sensors are fixed on a bracket. When the temperature sensor is in a fixed position for long-term monitoring, it may be interfered by surrounding environmental factors. For example, the sensor may be blocked by surrounding buildings, vegetation or other obstacles, causing the monitoring results to be affected to a certain extent, resulting in the detected temperature being not accurate enough.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a remote sensing monitoring device for temperature changes in a wheat field, comprising a bottom plate 1, a support rod 11 is fixedly connected to the top of the bottom plate 1, a mounting frame 12 is fixedly connected to the surface of the support rod 11, a distribution box 13 is fixedly connected to one side of the mounting frame 12, a fixed plate 14 is fixedly connected to the top of the support rod 11, a monitoring mechanism 2 is arranged on the surface of the fixed plate 14, the monitoring mechanism 2 comprises a moving unit 21 and a switching unit 22, the moving unit 21 comprises a transmission shaft 21 rotatably connected to the inner cavity of the fixed plate 14 01, there are two transmission shafts 2101, and the two transmission shafts 2101 are connected by a transmission belt 2102. The bottom of the transmission belt 2102 is fixedly connected with a first telescopic rod 2103, and the telescopic end of the first telescopic rod 2103 is fixedly connected with a mounting plate 2104. The bottom of the mounting plate 2104 is fixedly connected with a temperature sensor 2105. The switching unit 22 is used in conjunction with the moving unit 21. The switching unit 22 is used to switch the driving mode of the transmission shaft 2101. A spraying mechanism 3 is arranged on one side of the base plate 1.

[0034] As a further limitation of the monitoring mechanism 2 of the present invention, the mobile unit 21 includes a connecting plate 2106 fixedly installed on both sides of the fixed plate 14, a lifting frame 2107 is fixedly connected between the opposite sides of the two connecting plates 2106, a fixing rod 2108 is fixedly connected to the bottom of the mounting plate 2104, and the inner cavity of the fixing rod 2108 is rotatably connected to the first ball 2109, the surface of the first ball 2109 contacts the top of the lifting frame 2107, an arc groove 2110 is opened at the bottom of the fixed plate 14, and the surface of the first telescopic rod 2103 contacts the inner wall of the arc groove 2110. By setting the mobile unit 21, the transmission shaft 2101 can be rotated. The transmission belt 2102 drives the first telescopic rod 2103 to move in the inner cavity of the arc groove 2110. When the first telescopic rod 2103 moves, the lifting frame 2107 is set, and the first telescopic rod 2103 moves to the concave part of the lifting frame 2107, and the first telescopic rod 2103 is extended by its own gravity. When the first telescopic rod 2103 moves to the protrusion of the lifting frame 2107, the telescopic end of the first telescopic rod 2103 is squeezed and contracted, thereby achieving the effect of moving the temperature sensor 2105 up and down, and increasing the accuracy of temperature monitoring.

By setting the second ball 2111, when the transmission belt 2102 is transmitted, the transmission belt 2102 will drive the second ball 2111 to rotate, thereby reducing the friction between the transmission belt 2102 and the inner wall of the fixed plate 14.

[0036] The specific implementation of this embodiment is as follows: when the temperature of the wheat field is detected, the temperature sensor 2105 is started, and the transmission shaft 2101 is rotated at this time, so that the transmission belt 2102 drives the first telescopic rod 2103 to move in the inner cavity of the arc groove 2110, wherein the first telescopic rod 2103 is divided into an inner rod and an outer rod, and the surface of the inner rod and the inner wall of the outer rod are both smoothly arranged, so that the first telescopic rod 2103 can be extended under the gravity of the inner rod itself, and the first ball bearing 2103 on the fixing rod 2108 is arranged by the lifting frame 2107. 09 will contact with the top of the lifting frame 2107. When the first telescopic rod 2103 is moving, the first ball 2109 will keep in contact with the lifting frame 2107, so that when the first telescopic rod 2103 moves to the recessed part of the lifting frame 2107, it will extend due to its own gravity. When the first telescopic rod 2103 moves to the raised part of the lifting frame 2107, the telescopic end of the first telescopic rod 2103 will be squeezed and contracted, thereby achieving the effect of moving the temperature sensor 2105 up and down, thereby increasing the accuracy of temperature monitoring.

[0037] Example 2: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a remote sensing monitoring device for temperature changes in wheat fields. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0038] As a further limitation of the monitoring mechanism 2 of the present invention, the switching unit 22 includes a rotating rod 2201 slidably connected to the inner cavity of the fixed plate 14, the number of the rotating rods 2201 is two, the surface of one of the rotating rods 2201 is fixedly connected to a long rod 2202, the number of the long rods 2202 is several, one end of the long rod 2202 is fixedly connected to a wind scoop 2203, the bottom of the fixed plate 14 is fixedly connected to an L-shaped rod 2204, the surface of the L-shaped rod 2204 is provided with a motor 2205, the output end of the motor 2205 is slidably connected to the bottom of the fixed plate 14, the bottom of the L-shaped rod 2204 is fixedly connected to a first electric telescopic rod 2206, the output end of the first electric telescopic rod 2206 passes through the L-shaped rod 2204 and is fixedly connected to the bottom of the motor 2205, the surface of the output end of the first electric telescopic rod 2206 slides with the inner cavity of the L-shaped rod 2204, and the top of the fixed plate 14 is fixedly connected to a second The electric telescopic rod 2207 and the telescopic end of the second electric telescopic rod 2207 are fixedly connected with an adjusting plate 2208. The surface of the rotating rod 2201 is rotatably connected to the inner cavity of the adjusting plate 2208 through a bearing. By setting a switching unit 22, when the wind force is strong, the wind scoop 2203 can be used to drive the rotating rod 2201 to rotate, thereby rotating the transmission shaft 2101. When the wind force is weak, the first electric telescopic rod 2206 drives the motor 2205 to move upward, and the second electric telescopic rod 2207 drives the rotating rod 2201 to move upward. At this time, the motor 2205 drives the transmission shaft 2101 to rotate. When the wind force becomes strong, the first electric telescopic rod 2206 drives the motor 2205 to move in the opposite direction, and the second electric telescopic rod 2207 drives the adjusting plate 2208 to move downward, thereby achieving the effect of switching the driving force of the transmission shaft 2101.

[0039] A first annular plate 2209 is fixedly connected to the top of the fixed plate 14, a short rod 2210 is fixedly connected to the top of the fixed plate 14, the number of the short rods 2210 is several, and the tops of the several short rods 2210 are commonly fixedly connected to a second annular plate 2211, a first switch 2212 is fixedly connected to the surface of the first annular plate 2209, a second switch 2213 is fixedly connected to the inner wall of the second annular plate 2211, a centrifugal component is provided on the surface of one of the rotating rods 2201, and by setting the first annular plate 2209, the second annular plate 2211, the centrifugal component, the short rod 2210, the first switch 2212 and the second switch 2213, when the wind scoop 2203 is driven by wind force to move in a circle, the rotating rod 2201 will rotate, thereby driving the transmission shaft 2101 to rotate, and when the wind force gradually decreases When the wind speed is small, the rotation speed of the rotating rod 2201 will slow down, and the centrifugal assembly will reset, so that the centrifugal assembly will contact the first switch 2212 on the first annular plate 2209. At this time, the first switch 2212 is started, so that the output end of the motor 2205 rotates, the first electric telescopic rod 2206 extends, and the second electric telescopic rod 2207 extends. When the wind force is strong, the rotation speed of the rotating rod 2201 will increase, so that the centrifugal assembly will contact the second switch 2213 on the second annular plate 2211, so that the output end of the motor 2205 stops rotating, the first electric telescopic rod 2206 contracts, and the second electric telescopic rod 2207 contracts, thereby achieving the effect of driving the transmission shaft 2101 to rotate by wind force, wherein the first switch 2212 and the second switch 2213 are both touch switches.

[0040] The centrifugal assembly includes a groove 2214 formed on the surface of one of the rotating rods 2201, the inner cavity of the groove 2214 is slidably connected with a touch rod 2215, one end of the touch rod 2215 is fixedly connected with a tension spring 2216, and the other end of the tension spring 2216 is fixedly connected to the inner wall of the groove 2214. By setting the centrifugal assembly, when the rotating rod 2201 is rotated faster, the centrifugal force will drive the touch rod 2215 to move, and at this time the tension spring 2216 is stretched. When the rotating rod 2201 rotates slower, the tension spring 2216 is stretched. 6 will drive the touch rod 2215 to reset. At this time, the touch rod 2215 will contact the first switch 2212 when it moves in a circular shape. At this time, the rotating rod 2201 is cancelled to drive the transmission shaft 2101 to rotate. When the rotating rod 2201 rotates faster, the spring 2219 will be stretched, so that the touch rod 2215 can move to a certain extent. When the touch rod 2215 contacts the second switch 2213, the second switch 2213 is activated to make the rotating rod 2201 drive the transmission shaft 2101 to rotate.

[0041] A pressure rod 2217 is fixedly connected to the top of the fixed plate 14, and a pressure block 2218 is slidably connected to the inner cavity of the pressure rod 2217. One end of the pressure block 2218 is fixedly connected to a spring 2219, and the other end of the spring 2219 is fixedly connected to the inner wall of the pressure rod 2217. A ring block 2220 used in conjunction with the pressure block 2218 is fixedly sleeved on the surface of one of the rotating rods 2201. By setting the pressure block 2218, the pressure rod 2217, the spring 2219 and the ring block 2220 for use together, when the rotating rod 2201 is moved to When the rotating rod 2201 moves upward, the annular block 2220 will move upward. At this time, the pressure rod 2217 generates a certain pressure on the annular block 2220 under the action of the spring 2219, so that after the rotating rod 2201 is separated from the transmission shaft 2101, the rotation of the rotating rod 2201 will still have a certain resistance. The resistance is basically the same as the resistance of the rotating rod 2201 to drive the transmission shaft 2101 to rotate. Even if the rotating rod 2201 is separated from the inner cavity of the transmission shaft 2101, the state of the rotating rod 2201 in the inner cavity of the transmission shaft 2101 can also be simulated.

[0042] A card slot 2221 is provided at the top and bottom of the transmission shaft 2101, and a card block 2222 is fixedly connected to the output end of the motor 2205 and the bottom end of the rotating rod 2201. The opposite sides of the two card blocks 2222 are inclined. By setting the card slot 2221 and the card block 2222 for coordinated use, since one end of the card block 2222 is inclined, the card block 2222 is conveniently connected to the card slot 2221, and the card block 2222 and the card slot 2221 are both polygonal.

[0043] The specific implementation of this embodiment is as follows: when the wind force is strong, the wind scoop 2203 can drive the rotating rod 2201 to rotate, thereby rotating the transmission shaft 2101. When the wind force gradually decreases, the rotation speed of the rotating rod 2201 will slow down, and the force deformation of the tension spring 2216 will drive the touch rod 2215 to reset. At this time, the touch rod 2215 will contact the first switch 2212 when it moves in a circular shape. At this time, the first switch 2212 is activated, so that the motor 220 5 rotates, the first electric telescopic rod 2206 and the second electric telescopic rod 2207 extend, at this time, the block 2222 on the rotating rod 2201 disengages from the slot 2221 on the transmission shaft 2101, and the block 2222 on the output end of the motor 2205 is inserted into the slot 2221 at the bottom of the transmission shaft 2101. When the wind force is strong, the rotating rod 2201 rotates faster, and the spring 2219 is stretched, so that the touch rod 2215 moves to a certain extent. When the touch rod 2215 contacts the second switch 2213, the output end of the motor 2205 stops rotating, the first electric telescopic rod 2206 contracts, and the second electric telescopic rod 2207 contracts, so that the wind drives the transmission shaft 2101 to rotate. At this time, the block 2222 on the rotating rod 2201 is inserted into the slot 2221 on the transmission shaft 2101, and the block 2222 on the output end of the motor 2205 is disengaged from the slot 2221 at the bottom of the transmission shaft 2101. 1, thereby achieving the effect of switching the driving force of the transmission shaft 2101, and when the rotating rod 2201 moves upward, the annular block 2220 will move upward. At this time, the pressure rod 2217 generates a certain pressure on the annular block 2220 under the action of the spring 2219, so that after the rotating rod 2201 is separated from the transmission shaft 2101, the rotation of the rotating rod 2201 still has a certain resistance, and the resistance is basically the same as the resistance of the rotating rod 2201 to drive the transmission shaft 2101 to rotate.

By setting a spraying mechanism 3, in winter, when the temperature sensor 2105 detects that the temperature drops to a certain value, a signal can be transmitted to the controller 307, thereby starting the water pump 302. The water pump 302 can spray the nutrient foliar fertilizer solution in the liquid storage tank 301 into the wheat field to prevent and reduce the occurrence of low temperature damage. The controller 307 has a cycle timing function, which can control the water pump 302 to start only once in a cycle according to a set cycle, and the cycle is usually 10 to 15 days, thereby avoiding the water pump 302 being in a working state all the time.

[0046] The specific implementation of this embodiment is as follows: in winter, since the temperature sensor 2105 and the controller 307 are connected by electrical signals, the temperature sensor 2105 uses a wireless temperature sensor with a built-in power supply. When the temperature sensor 2105 detects that the temperature has dropped to a certain value, it can transmit a signal to the controller 307, thereby starting the water pump 302. The nutrient foliar fertilizer solution in the liquid storage tank 301 can be transported to the insertion rod 304, the short tube 308 and the long tube 305 through the water pump 302, and then sprayed into the wheat field through the sprinkler head 306 to prevent and reduce the occurrence of low temperature damage, wherein the nutrient foliar fertilizer solution can be stored in the inner cavity of the liquid storage tank 301 in advance.
