Description

Technical Field

[0001] The invention relates to the field of agricultural detection. Background Art

[0002] The sensor is generally composed of three parts: sensitive element, conversion element, and signal conditioning and conversion circuit. Sometimes an external auxiliary power supply is required to provide conversion energy. The sensitive element refers to the part of the sensor that can directly sense or respond to the measured value; the conversion element refers to the part of the sensor that can convert the measured value sensed or responded by the sensitive element into an electrical signal suitable for transmission or measurement. Since the output signal of the sensor is generally very weak, the output signal of the sensor generally needs to be conditioned and converted, amplified, calculated and modulated before it can be displayed and controlled.

[0003] The sensor consists of four parts: sensitive element, conversion element, conversion circuit and auxiliary power supply. Among them, the sensitive element directly receives the measurement and is used to output the physical quantity signal related to the measurement. The sensitive elements mainly include ten categories: thermal, light, humidity, gas, force, sound, magnetism, color, taste, and radioactivity. The conversion element is used to convert the physical quantity signal output by the sensitive element into an electrical signal. The conversion circuit is used to amplify, modulate, and process the electrical signal output by the conversion element. The auxiliary power supply is used to provide energy for the system (mainly the sensitive element and the conversion element).

[0004] The working principle of solar panels is to use the photoelectric effect, also known as the photovoltaic effect. The photovoltaic effect refers to the phenomenon that an object generates an electromotive force due to the absorption of photons. It is an effect in which the charge distribution state in an object changes when the object is exposed to light, generating electromotive force and current. When sunlight or other light shines on the PN junction of a semiconductor, the photovoltaic effect occurs. The photovoltaic effect causes a voltage to appear on both sides of the PN junction, which is called photogenerated voltage. If the PN junction is short-circuited, current will be generated.

[0005] There is a trend now, which is to use integrated circuit-like methods to realize the functions of sensors, which is a bit like putting discrete devices into integrated circuits in the past. The advantage of doing this is that the cost, stability, and power consumption can be well controlled, which is also the charm of integrated circuits. This is the MEMS sensor, a stable and controllable sensor that can be wirelessly charged.

[0006] However, the above sensors all exist separately and act in their own fields. For example, the public document with announcement number CN114264794A, publication date 2022-04-01, and patent name "An agricultural sensor assembly and a soil detection device using the sensor assembly" discloses an agricultural sensor assembly and a soil detection device using the sensor assembly. The present invention relates to an agricultural sensor assembly, comprising: a support frame fixed on the device body, a driving cylinder vertically fixed on the support frame, and a detection assembly fixed on the end of the piston rod of the driving cylinder; the detection assembly comprises: a detection ring, a plurality of sensors and a plurality of linkage columns, a fixed plate is fixed on the end of the piston rod of the driving cylinder, and the detection ring is fixed on the lower end of the fixed plate; the detection ring is hollow inside, and a plurality of sliding grooves are opened axially on the outer wall of the detection ring, and the linkage column can be slidably arranged in the sliding groove; one sensor corresponds to one linkage column, and the sensor can be slidably arranged on the inner wall of the detection ring, and the sensor is suitable for detecting soil; wherein after the soil to be detected enters the inside of the detection ring, the linkage column is pushed downward in turn to drive the sensor to slide downward synchronously, so that the sensor can detect the soil quality multiple times. Therefore, there is a lack of a combined sensor device that can achieve self-sufficiency in power supply and independently complete the required detection and sensing tasks. Summary of the invention

[0007] The technical problem to be solved by the present invention is to realize a sensor system with a self-supply function, which can efficiently detect the planting of farmland and rice fields and avoid the troubles of wiring and other problems.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a self-supplied sensor system for agricultural monitoring, the device is provided with a column, the bottom of the column is provided with a base for fixing on the ground, the top of the column is provided with a solar panel, a battery is fixed under the solar panel, the power output end of the solar panel is connected to the battery and charges the battery, a sensor assembly is fixed on the column, the sensor assembly includes a shell, and a communication module fixed in the shell and a sensor for collecting environmental parameter information, the power supply end of the communication module and the sensor is connected to the battery through a power cord, the signal output end of the sensor is connected to the communication module, and the communication module transmits the parameter information collected by the sensor to a designated receiving site.

[0009] The column is an iron column with an anti-rust coating on its surface. One side of the sensor component housing is provided with a magnet for adsorbing on the column, and the sensor component is fixed on the column by adsorption.

[0010] The power cord of the sensor assembly extends out from the shell, the connection between the power cord and the shell is sealed, a plug is provided at the end of the power cord, and a socket for power supply is provided on the battery.

[0011] An antenna is provided in the frame of the solar panel, and a signal line is provided next to the power line. One end of the signal line is connected to the communication module, and the other end is connected to the communication electrical connection point on the plug. An electrical contact point that cooperates with the communication electrical connection point is provided on the socket, and the electrical contact point is connected to the antenna through a wire.

[0012] The socket is located on the lower surface of the battery, and a circle of wind and water-proof eaves protruding downwards is provided on the outer periphery of the socket.

[0013] The sensor assembly comprises an outdoor assembly and an indoor assembly. The top end of the column extends out of the greenhouse. The outdoor assembly is adsorbed and fixed on the column inside the greenhouse. The indoor assembly is adsorbed on the column outside the greenhouse.

[0014] The column is a retractable cylindrical structure, and is equipped with two sealing splints. The sealing splints are annular rubber sheets. The inner ring of the sealing splints fits tightly with the column. One side of the sealing splint is open, one of the sealing splints is provided with a soft magnetic plate, and the other sealing splint is provided with a soft iron film. The two sealing splints are used to clamp the greenhouse film where the column passes through the greenhouse.

Its appearance and composition are almost different from traditional sensors, and no wiring or power supply is required. At the same time, the structural design of our multifunctional sensor is convenient for users to operate in daily farmland detection.

[0020] 2. The inspection scope is expanded. This new product is different from the previous sensor detection products. In the past, traditional sensor detection products were often fixed in a designated greenhouse or other small location, and then the personnel to be tested went to the designated detection location to test the soil material content. The above detection method increased the detection time and also increased the workload of the testers. However, this product is fixed in the farmland, and the data will be uploaded regularly. The testers can complete the test by checking the data information regularly, which greatly saves working time and detection workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0026] The self-supply sensor system for agricultural monitoring utilizes the principle of sensors, and the detection of farmland and rice field planting is realized by inserting a sensor rod. The sensor rod needs to be provided with a column 2, which is a rod-shaped structure, and preferably an iron telescopic rod, so that the length of the column 2 can be adjusted as needed to adapt to the height requirements of the column 2 in different scenarios. The telescopic form of the column 2 can be implemented according to existing feasible solutions as needed.

[0027] The column 2 needs to be fixed vertically on the ground when in use. Therefore, a base 4 for fixing on the ground is provided at the bottom of the column 2. In order to facilitate fixing on the mud and cement pouring, the base 4 adopts two embodiments;

[0028] Embodiment 1 is used on cement cast ground. It is necessary to set a fixing seat on the ground in the form of pre-embedded casting. A plurality of bolt columns protruding from the ground are provided above the fixing seat. Generally, four bolt columns are provided at four corners. A mounting flange is provided on the bottom surface of the column 2. Mounting holes are provided on the edge of the mounting flange. The position of each mounting hole corresponds to the position of the bolt column. In this way, the bolt column is inserted into the mounting hole, and the screws are tightened in sequence to fix the column 2.

[0029] Embodiment 2, when used on muddy ground, needs to pre-dig a pit, the size of which should be deeper than the sleeve, and the sleeve is preferably in the shape of a cone, so that the force can be better applied to the bottom and the probability of tilting can be reduced. After the sleeve is embedded, the hole is filled but the insertion hole at the top of the sleeve needs to be exposed, and then the backfill is compacted. A downwardly extending insertion rod is provided at the bottom of the column 2, and the insertion rod is an extension of the column 2. The internal aperture of the insertion hole matches the clearance of the insertion rod, and the insertion rod can be inserted after the backfill is compacted. Preferably, the insertion hole in the sleeve is a through hole, and the end of the insertion rod is a gradually tapering needle rod structure, so that the end of the insertion rod can be used as a guide, and can also be further inserted into the soil after being inserted into the sleeve, thereby improving the reliability of the fixation of the entire base 4.

[0030] The above two embodiments can be selected and used according to the specific installation ground.

[0031] A solar panel 1 is provided on the top of the column 2, and a battery is fixed under the solar panel 1. The power output end of the solar panel 1 is connected to the battery and charges the battery. Placing the battery externally is convenient for replacing the battery and for repairing the battery. For example, in continuous rainy weather, when sufficient charging cannot be provided, the battery can be replaced regularly as needed. The external battery is also convenient for repair, and the battery is fixed under the solar panel 1, which can also shield it from wind and rain, providing a better working environment for the battery.

[0032] A sensor assembly 3 is fixed on the column 2. The sensor assembly 3 includes a shell, a communication module fixed in the shell, and a sensor for collecting environmental parameter information. The communication module is used to send the collected data wirelessly. The sensor can be set according to the experimental requirements, such as setting a temperature sensor, a humidity sensor, an air volume sensor, a MEMS sensor, etc. The specific number and type can be adjusted as needed. The sensor and the communication module are fixed in the shell, and the shell is watertight to ensure the safety and reliability of outdoor use. Of course, the detection part of the sensor needs to extend out of the shell to contact the outside as needed.

[0033] The power supply end of the communication module and the sensor is connected to the battery through a power line, and the signal output end of the sensor is connected to the communication module. The communication module transmits the parameter information collected by the sensor to the designated receiving site. The designated receiving site includes PDA, mobile phone, cloud, server and / or computer equipment in the monitoring station.

[0034] In order to facilitate fixing the position of the sensor assembly 3 as needed, the column 2 is an iron column with an anti-rust coating on the surface. One side of the shell of the sensor assembly 3 is provided with a magnet for adsorbing on the column 2. If the surface of the column is arc-shaped, the surface of the shell with the magnet needs to be made into a shape matching the surface shape of the column 2. The sensor assembly 3 is fixed on the column 2 by adsorption to ensure the reliability of adsorption.

[0035] The power cord of the sensor component 3 extends from the shell, the connection between the power cord and the shell is sealed, a plug is provided at the end of the power cord, and a socket for power supply is provided on the battery. The external plug-in method is adopted to make each component independent of each other, which is convenient for better adjustment and position adjustment. If the actual scene is a greenhouse or indoors, it may be necessary to collect indoor and outdoor environmental parameter information at the same time. The sensor component 3 includes an outdoor component and an indoor component. The top of the column 2 extends out of the greenhouse, and the outdoor component is adsorbed and fixed on the column 2 inside the greenhouse, and the outdoor component is adsorbed on the column 2 outside the greenhouse.

[0036] Because the fixed position of the sensor assembly 3 may be indoors, the corresponding signal transmission may be affected. Therefore, an antenna is provided in the frame of the solar panel 1. The antenna is fixed at a high position and is large enough to improve the stability and reliability of signal transmission. A signal line is provided next to the power line. If the current interferes with the signal, it needs to be wrapped with a shielding layer. One end of the signal line is connected to the communication module, and the other end is connected to the communication electrical connection point on the plug. The power line and the signal line are an integral wiring harness, and the connection method is also completed at one time. The jack is provided with an electrical contact point that cooperates with the communication electrical connection point. The electrical contact point is connected to the antenna through a wire, so the plug-in relationship requires different contact electrical connection positions. In order to prevent water from entering the plug-in position, the jack is located on the lower surface of the battery, and a circle of downwardly protruding wind and water-proof eaves is provided on the outer periphery of the jack. In this way, even if the plug is placed outdoors, wind and rain weather will have almost no effect on it.

[0037] Because the column 2 needs to pass through the indoor and outdoor environment, the corresponding sealed environment may be damaged, so two sealing splints are provided on the column 2, such as Figure 2 As shown, the sealing splint is an annular rubber sheet with certain toughness. It can be bent and attached to the opening position. The inner circle of the sealing splint cooperates with the column 2 to ensure the sealing performance of the inner circle. One side of the sealing splint is open and can be easily inserted into the column 2. One of the sealing splints is provided with a soft magnetic plate, and the other sealing splint is provided with a soft iron film. The two sealing splints are used to clamp the greenhouse film at the place where the column 2 passes through the greenhouse. The sealing performance of the opening can be solved in a simple and reliable way, and the monitoring device can be prevented from damaging the greenhouse energy environment.

[0038] In general, the appearance of this sensor is very different from that of a normal sensor. By applying the sensor group to the sensor arm for observation and fixing the solar panel 1 on the top of the sensor rod, the solar technology and sensor technology are combined to act on the sensor rod, and the solar sensor can be automatically assembled, disassembled, and combined, so that it is more suitable for harsh conditions such as farmland, forming a multifunctional assembled solar sensor for farmland detection. This product can solve the farmland detection work that needs to be detected and meet the needs of traditional sensors that cannot be used. Traditional sensors are suitable for greenhouse vegetable and fruit planting. Greenhouses and other places are small, there is no wind or rain, and a series of operations such as sensor charging are simple. It is difficult to replace the damaged sensor. China is a country with a lot of farmland. For farmland planting, sensors suitable for greenhouses have long been unsuitable for various large farmlands and rice fields. Even the recently popular MEMS sensors are not very useful for farmland planting detection, because its wireless charging and other operations require the sensor signal source to be very close to the sensor to work, and compared with greenhouses, farmlands make it difficult for MEMS and other sensors to work. And our sensors can be assembled and disassembled, which is conducive to transportation. Our multifunctional assembled solar sensor for farmland detection just solves these shortcomings. It charges itself and can improve detection efficiency, increase detection speed and reduce work costs through large-scale multiple detection.

[0039] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
