Description

Technical Field

[0001] The utility model relates to the technical field of soil monitoring, in particular to an agricultural information-based soil temperature and humidity monitoring device. Background Art

[0002] In order to make crops grow better during the growth process, the temperature and humidity of the soil where crops are planted are usually monitored to understand the temperature and humidity in the soil and adjust the temperature and humidity of the soil in time, thereby promoting better growth of crops and ensuring crop yields.

[0003] The existing patent application number: CN202121206293.0 discloses an agricultural soil temperature and humidity monitoring device: "including a monitoring device body, a connecting wire is fixedly installed on the top of the monitoring device body, a solar panel is arranged at one end of the connecting wire away from the monitoring device body, and a support rod is fixedly installed at the bottom of the solar panel..." Although the above patent application can monitor soil temperature and humidity, it still has the following defects in daily use:

[0004] (1) Since the connection between the bottom of the solar panel and the support rod in CN202121206293.0 is a fixed connection, when the sun's radiation angle is different, the solar panel cannot adjust its own angle accordingly according to the change in the sun's radiation angle, which leads to low power generation efficiency of the solar panel.

[0005] (2) Although CN202121206293.0 discloses a monitoring device for monitoring soil moisture, the monitoring device does not realize wireless communication with the remote monitoring equipment. When it is necessary to understand the real-time temperature and humidity of the soil, the personnel responsible for monitoring the temperature and humidity of the soil need to be on site to check the data monitored by the monitoring device. If the monitoring personnel are not on site or on a business trip, the work of monitoring the temperature and humidity of the soil can only be put on hold. This not only brings great inconvenience to the monitoring work, but also makes it impossible to understand the real-time temperature and humidity of the soil in a timely manner, and thus it is impossible to adjust the temperature and humidity of the soil in real time.

[0006] Therefore, it is necessary to improve and design the existing device for monitoring soil temperature and humidity to solve the problem that the solar panel power generation components on the existing soil temperature and humidity monitoring devices cannot adjust their own angle of absorbing sunlight in time according to changes in the angle of sunlight, and cannot timely understand the real-time temperature and humidity of the soil.

[0038] Among them, the photovoltaic component 2 for adjusting the expansion angle to realize the charging function includes a solar panel 11, a connecting rod 14, a connecting rod 2 16, a slider 12 and an electric push rod 13; the solar panel 11 is used to absorb sunlight and cooperate with the charging and discharging module 6 to power the lithium battery 7, the single-chip computer 8 and the wireless transmission module 9; the electric push rod 13, the slider 12, the connecting rod 14 and the connecting rod 2 16 cooperate to drive the slider 12 to move through the electric push rod 13, so that the moving slider 12 drives the solar panel 11 to expand into expansion surfaces of different angles through the connecting rod 2 16 and the connecting rod 1 14 to adapt to the solar radiation angle in different time periods.

[0039] Specifically, the solar panel 11 is electrically connected to the lithium battery 7 through the charging and discharging module 6, and the two ends of the solar panel 11 are rotatably connected to the fixed ears 15 on the outer wall of the placement box 1 through the connecting rod 14, one end of the connecting rod 14 is hinged to one end of the connecting rod 2 16, and the other end of the connecting rod 2 16 is rotatably connected to the upper part of the slider 12, and the slider 12 is slidably connected to the slide grooves 17 set on the two side walls of the placement box 1, one end of the slider 12 is connected to the driving end of the electric push rod 13, and the fixed end of the electric push rod 13 is connected to one end of the slot 17.

[0041] It should be noted that, in order to avoid interference between the second connecting rod 16 connected to the upper portion of the slider 12 during rotation, a certain distance is reserved between the two second connecting rods 16 connected to the upper portion of the slider 12 .

[0042] In actual use, when monitoring the temperature and humidity of the soil, the plug-in rod 5 is inserted into the soil whose temperature and humidity need to be monitored, and the soil is submerged in the entry groove 10.

[0044] See also Figure 1 , Figure 2 , Figure 3 and Figure 8In order to remotely transmit the monitored soil temperature and humidity information to the management personnel responsible for monitoring, a charging and discharging module 6, a lithium battery 7, a single-chip microcomputer 8 and a wireless transmission module 9 are provided inside the placement box 1. The temperature and humidity sensor 4 and the wireless transmission module 9 are connected to the single-chip microcomputer 8. The solar panel 11 is electrically connected to the lithium battery 7 through the charging and discharging module 6. The lithium battery 7 provides power to the temperature and humidity sensor 4, the single-chip microcomputer 8 and the wireless transmission module 9 through the charging and discharging module 6. The temperature and humidity data in the single-chip microcomputer 8 are uploaded to the cloud through the wireless transmission module 9 and the signal base station, and the temperature and humidity data are obtained from the cloud through the PC or mobile terminal.

[0045] It should be noted that the single-chip microcomputer 8 and the wireless transmission module 9 are both prior arts, wherein the single-chip microcomputer 8 is an STM32 main control chip, and the wireless transmission module 9 is an NBloT wireless transmission module.

[0046] It should be noted that the charging and discharging module 6 is a prior art, and no modification or design has been made thereto, so its structure will not be described in detail.

[0047] In actual use, when the monitored soil temperature and humidity information needs to be transmitted to the monitoring personnel, the temperature and humidity sensor 4 first transmits the monitored information to the single-chip microcomputer 8 for processing, and the processed information is transmitted to the cloud through the wireless transmission module 9 and the signal base station. The management personnel responsible for monitoring can obtain the soil temperature and humidity data from the cloud through the PC or mobile terminal.

[0048] See also Figure 2 In order to protect the temperature and humidity sensor 4, a rubber sleeve 18 is provided between the temperature and humidity sensor 4 and the connecting sleeve 3. Specifically, the rubber sleeve 18 is internally sleeved on the temperature and humidity sensor 4, and the rubber sleeve 18 is externally sleeved on the connecting sleeve 3.

[0049] In actual use, if the connecting sleeve 4 is subjected to vibration, since a rubber sleeve 18 is provided between the temperature and humidity sensor 4 and the connecting sleeve 3, the rubber sleeve 18 will buffer the vibration transmitted from the connecting sleeve 4, thereby further reducing the vibration of the temperature and humidity sensor 4, and indirectly improving the protection of the temperature and humidity sensor 4.

[0050] See also Figure 1 and Figure 2 A plurality of entry grooves 10 for allowing soil to enter the monitoring area of ​​the temperature and humidity sensor 4 probe are opened along the outer wall of the plug-in rod 5. The plurality of entry grooves 10 are arranged in a ring shape, and each entry groove 10 is set to a rectangular structure.

[0051] In actual use, when the soil whose temperature and humidity need to be monitored enters the monitoring area of ​​the temperature and humidity sensor 4 probe, the plug-in rod 5 is inserted into the soil whose temperature and humidity need to be monitored, and the soil is submerged in the entry groove 10. The soil enters the monitoring area of ​​the temperature and humidity sensor 4 probe from several entry grooves 10, and the temperature and humidity sensor 4 probe monitors the temperature and humidity of the soil.

[0052] In this solution, by opening a plurality of entry grooves 10 along the outer wall of the plug-in rod 5, the soil whose temperature and humidity need to be monitored can enter the monitoring area of ​​the temperature and humidity sensor 4 probe through the plurality of entry grooves 10 in a short time, and a large amount of soil can be monitored.

[0053] See also Figure 2 and Figure 3 In order to make it easier for the plug rod 5 to be inserted into the ground, the end of the plug rod 5 away from the cavity 23 is set to a V-shaped structure, wherein the surface of the V-shaped contour of the plug rod is also coated with a wear-resistant layer, and the contour of the wear-resistant layer is V-shaped, wherein the wear-resistant layer is a wear-resistant coating to improve the wear resistance of the V-shaped end of the plug rod.

[0054] In actual use, when the plug-in rod 5 is inserted into the soil whose temperature and humidity need to be monitored, since the V-shaped end of the plug-in rod 5 is inserted into the soil, the contact area between the V-shaped plug-in rod and the soil is small, and the resistance encountered by the plug-in rod 5 during movement is relatively small, so the plug-in rod 5 can be easily plugged into the soil.

[0055] In addition, in order to realize the threaded connection between the plug-in rod 5 and the connecting sleeve 3, a cavity 23 is provided at one end of the plug-in rod 5 and an external thread is provided, and the external thread is connected to the internal thread at one end of the connecting sleeve 3.

[0056] In actual use, if the plug-in rod 5 is damaged during use, the damaged plug-in rod 5 and the connecting sleeve 3 can be disassembled, and then the new plug-in rod 5 and the connecting sleeve 3 can be threadedly connected, so as to avoid the situation where the plug-in rod 5 and the connecting sleeve 3 are integrally formed and the entirety needs to be replaced, resulting in a waste of materials; in addition, if the length of the plug-in rod 5 does not meet the actual required length, since the plug-in rod 5 and the connecting sleeve 3 are threadedly connected, the plug-in rod 5 of the corresponding length can be threadedly connected to the connecting sleeve 3, thereby further improving the practicality of the device.

[0057] It should be noted that in order to avoid rust on the connecting sleeve 3 and the plug-in rod 5, the material of the connecting sleeve 3 and the plug-in rod 5 is set to stainless steel, wherein the outer walls of the connecting sleeve 3 and the plug-in rod 4 are also coated with a waterproof layer respectively, the waterproof layer is a ring structure, and the waterproof layer is a waterproof coating.

[0058] See also Figure 1 and Figure 3The placement box 1 for placing the charging and discharging module 6, the lithium battery 7, the single-chip microcomputer 8 and the wireless transmission module 9 includes a box cover 19 and a box body 20; wherein the box cover 19 is used to cover and the box body 20; the box body 20 is used to place the charging and discharging module 6, the lithium battery 7, the single-chip microcomputer 8 and the wireless transmission module 9.

[0059] Specifically, the box cover 19 is a rectangular stainless steel plate, and columnar plug-in columns 21 are respectively arranged at the four corners of the box cover 19. The plug-in columns 21 are respectively plugged into the plug pin holes 22, and the plug pin holes 22 are respectively connected to the four corners of the box body 20. The lithium battery 7 and the charging and discharging module 6 are both located on the inner rear wall of the box body 20, and the single-chip computer 8 and the wireless transmission module 9 are respectively located on the two inner side walls of the box body 20.

[0060] In actual use, if any one of the discharge module 6, lithium battery 7, single-chip microcomputer 8 and wireless transmission module 9 in the box body 20 fails, since the box cover 19 is plugged into the plug pin hole 22 on the box body 20 through the plug column 21, the box cover 19 can be detached from the box body 20 to replace or repair the faulty charge and discharge module 6, lithium battery 7, single-chip microcomputer 8 and wireless transmission module 9 in the box body 20.
