DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

To better illustrate the invention and to facilitate the understanding of the technical solutions thereof, typical but non-limiting examples of the invention are as follows:

example 1

As shown in FIG. 1, the intelligent irrigation system of the present invention comprises a meteorological satellite 1, a processor 2, a sensor system 3 and a pressure control valve 4; wherein the sensor system 3 comprises: a temperature sensor, an air humidity sensor, a soil humidity sensor, an illumination sensor and a PIR sensor; the temperature sensor is used for detecting the temperature of the crop growing environment, and the air humidity sensor is used for detecting the air humidity of the crop growing environment; the soil humidity sensor is used for detecting the soil humidity of the crop growth environment; the PIR sensor is used for detecting motion; the pressure control valve 4 is used for adjusting water pressure to irrigate crops; the processor 2 comprises a controller and a transceiver; the processor 2 is connected to the sensor system 3 and the pressure control valve 4 via a wireless network.

For the purpose of monitoring the earth's environment, the satellite-based wireless sensor network is distributed throughout any area, which may be, alternatively, a county, a city, a province, and where possible, the sensor network may be arranged nationwide. Various environmental and climate data may be collected for continuous storage in the server. With the availability of satellite technology for environmental monitoring in a short time and low cost budget, any country will be acceptable.

The meteorological satellite 1 is used to collect meteorological data for a particular region, which may be referred to as a particular irrigation region. The data collected by the meteorological satellite 1 is transmitted to the ground via an S-band telemetry system and then to the processor 2.

The receiver system inquires about the area through which the meteorological satellite 1 passes, and starts to transmit the data of the data when confirming that the gateway of the meteorological satellite 1 is the same as the gateway address of the receiver system; the receiver uses the ax.25 protocol at 4800/9600 baud to allow data relating to the environment to be downloaded to the processor 2 in a shorter time. The receiver employs a deployable monopole antenna with a gain of about 2.5 dBi. It is retracted and deployed after initial deployment; the receiver employs a 32-way flash memory for storing the data.

There are many ways of communicating between the satellite and the receiver, but in either case, it is necessary to determine the real-time position of the satellite and the position of the receiver. For location determination, the present invention uses the gateway address to correlate the actual location of the receiver. The method has the advantages that the method can conveniently determine the positions of receivers at other positions adjacent to the receiver besides determining the gateway address position of the area, and the technical scheme of the invention does not need to carry out complicated destination visiting and inquiring. And after the gateway addresses of the receivers in other adjacent positions are obtained, the real-time meteorological satellite signals related to the gateway addresses can be downloaded and analyzed to obtain the meteorological conditions of optional adjacent areas.

In this embodiment, it should be clear that the information of the adjacent position can be conveniently obtained at any time, and the weather information of the area can be corrected to obtain more accurate weather conditions. The information of the adjacent position can be obtained optionally, and the meteorological information which has weak influence on the climate of the local area in the adjacent area is not obtained. This is achieved by a high facility of acquisition of the gateway address.

Specifically, when the receiver is arranged, an IP address, for example 192.168.1.43, is set as the IP address of the receiver in the area. In addition, the IP addresses of its neighboring areas are assigned and stored in the database. For example, the stored IP addresses are: 192.168.1.46, respectively; 192.168.1.48, respectively; 192.168.1.50; 192.168.1.52. the number of adjacent zones is variable but follows the principle of one zone per receiver. The size of the adjacent region is also variable, but for refinement of the information, to improve accuracy, a typical adjacent region may be 30-50km²But according to the ground typeMay be different. When weather information of the approach machine needs to be acquired, if a weather satellite passes through one or more adjacent areas before passing through the area where the weather information needs to be acquired, the weather information of the adjacent areas is read in advance; when the meteorological satellite passes through the area, the meteorological information of the area is read, the meteorological information of the adjacent area which is read in advance is superposed on the meteorological information of the area, and the processor processes the meteorological information and corrects the meteorological information of the area. The correction process may be performed using meteorological models known in the art. In addition, a plurality of adjacent areas may be selected, and when there are a plurality of adjacent area weather information, the plurality of area information may be selected to find appropriate correction weather information.

A temperature sensor, an air humidity sensor, a soil humidity sensor, an illumination sensor and a PIR sensor in the sensor system 3 are fixedly arranged on the crop growth environment and used for detecting various data corresponding to the crop growth environment; the PIR sensor is bound with each other sensor and is used for detecting whether the other sensors have abnormal displacement, unexpected events of farmland environment such as human or animal intrusion monitoring are lacked in the prior art, the PIR sensor can be used for timely finding the human or animal intrusion, and the invention is also one of the invention points; the sensor system 3 can continuously monitor environmental parameters, hydrological parameters and soil parameters; meanwhile, the processor 2 also stores specific demand ranges of different crops for environmental parameters, hydrological parameters, soil parameters and the like, and the processor 2 can be set to automatically control the pressure control valve 4 to irrigate or not according to the specific demand ranges.

Meanwhile, the processor 2 sends the monitored data such as meteorological data, environmental data, hydrological parameters, soil parameters and the like and the specific operation of irrigation or not to the user terminal through the network, and the user can inquire through related application. The user can also preset the specific demand ranges of various crops for meteorological data, environmental parameters, hydrological parameters, soil parameters and the like, and corresponding irrigation operations, and can also continue to manually control the operations of irrigation or not after receiving the meteorological data, environmental data, hydrological parameters, soil parameters and other data.

The irrigation device comprises: a container, an underground irrigation drip, a flexible pipe, a polyethylene wrap, an irrigation drip and a pressure control valve 4; the flexible pipe extends from the container, which is above ground, and is connected to the irrigation drip via an underground irrigation drip. When the irrigation device works, water flows out of the container, passes through the flexible pipe and the underground irrigation water dripping line, and finally flows out under the control of the pressure control valve 4 by the irrigation water dropper, and the pressure control valve 4 can control whether the water flows out or not and also can control the water quantity of the outflow water; the pressure control valve is arranged on the underground irrigation water dripping line, is electrically connected with the solar cell panel and is powered by the solar cell panel.

The container is used for containing liquid for plant irrigation, and the liquid for irrigation can be tap water or irrigation solution according to the respective demand proportion of various plants.

The flexible pipe is made from a natural or synthetic material, including, but not limited to, high density polyethylene ("HDPE"), medium density polyethylene ("MDPE"), copper, iron, lead pipe, thermoplastic polymers such as polyvinyl chloride ("PVC"), chlorinated polyvinyl chloride ("CPVC"), acrylonitrile-butadiene-styrene ("ABS"), crosslinked polyethylene ("PEX" plastic), pressure taps, or any other similar material that can help resist mildew, corrosion, and weather damage. Preferably, metal, such as a steel impermeable helical bellows (which is also a flexible tube), may also be used. The pipe is made of flexible materials and used for conveying water for irrigation, so that the flexible pipe can be conveniently bent and deformed in any shape; because the portable irrigation device is light, the portable irrigation device can be selectively and easily buried in soil besides being laid on the ground so as to meet various irrigation requirements.

Optionally, a wrapping layer is sleeved on the outer layer of the flexible pipe and used for wrapping the flexible pipe to enable the flexible pipe to be sleeved in the wrapping layer, so that the flexible pipe plays a role in protection. The material of the pipe sleeve is preferably polyethylene or the like. This ensures that the sleeve in which the flexible pipe is corroded by the surrounding environment. In field irrigation, the use of chemical products such as fertilizer application can cause long-term corrosion of hoses contacting the soil. And the use of a sleeve of, for example, a glue material, may effectively protect the flexible pipe from corrosive influences.

The polyethylene wrapping is preferably made from high density polyethylene ("HDPE"), medium density polyethylene ("MDPE"), thermoplastic polymers such as polyvinyl chloride ("PVC"), chlorinated polyvinyl chloride ("CPVC"), acrylonitrile-butadiene-styrene "ABS"), crosslinked polyethylene ("PEX" plastic), and the like.

The polyethylene wrap may prevent water from flowing out of the connection by simply tying, sealing, crimping, or otherwise inserting the wrap into the flexible pipe.

Because the water is conveyed by adopting the wrapping layer mode of the multilayer sleeve, the structure of the clamp in the existing structure can be improved, and the position of the clamp can be redesigned. For example, a clamp may be placed in the sandwich position.

The polyethylene sleeve wrapping layer of the irrigation device is used for wrapping the underground irrigation water dropper and the pressure control valve 4, and the irrigation water dropper extends out of the polyethylene wrapping layer to irrigate the root of crops; the end of the ethylene wrapping layer under the ground also comprises two clamps which are used for clamping the roots of the plants and simultaneously ensuring that the roots of the plants are not damaged.

Example 2

Fig. 2 shows an irrigation device comprising a container (not shown), a flexible tube 5, a wrapping 6, irrigation water drops 8, clamps 7, and root sensors 9.

Wherein the flexible tube 5 is connected to a drip irrigation drip 8. When the irrigation device works, water flows out from the container, passes through the flexible pipe 5, is controlled by the irrigation water dropper 8 through the pressure control valve 4 to flow out, and the pressure control valve 4 can control whether the water flows out or not and can also control the water quantity of the outflow water. The flexible tube 5 is made of a natural or synthetic material, including, but not limited to, high density polyethylene ("HDPE"), medium density polyethylene ("MDPE"), copper, iron, lead, thermoplastic polymers such as polyvinyl chloride ("PVC"), chlorinated polyvinyl chloride ("CPVC"), acrylonitrile-butadiene-styrene ("ABS"), crosslinked polyethylene ("PEX" plastic), pressure taps, or any other similar material that can help resist mildew, corrosion, and weather damage. Preferably, metal, such as a steel impermeable helical bellows (which is also a flexible tube), may also be used. As shown in fig. 3, a wrapping layer 6 is sleeved on the periphery of the flexible pipe 5, and the wrapping layer 6 is used for wrapping the flexible pipe so that the flexible pipe can be sleeved in the wrapping layer for protection. The material of the pipe sleeve is preferably polyethylene or the like. This ensures that the sleeve in which the flexible pipe is corroded by the surrounding environment. In field irrigation, the use of chemical products such as fertilizer application can cause long-term corrosion of hoses contacting the soil. And the use of a sleeve of, for example, a glue material, may effectively protect the flexible pipe from corrosive influences.

As shown in fig. 3-5, the flexible pipe 5 and the wrapping layer 6 thereon form a double-layer water delivery pipe, which can be clamped and fixed with the root part by using a clamp 7 more conveniently than the prior art. Compared with the clamp adopted in the prior art, the clamp 7 is arranged on the wrapping layer, does not influence the water delivery of the flexible pipe 5, and is arranged at the front end part of the wrapping layer. Figures 3-4 show the mounting position of the clamp 7, not on the side of the pipe, but on the front end of the wrapping 6. Compared with the installation fixed at the side position, the water flow direction or the water spraying direction of the conveying pipe is more favorably limited. When the jig 7 is attached to the tip end portion of the coating 6, the flexible tube 5 exposed from the coating 6 is closest to the same, and therefore the root portion is fixed at this position, which corresponds to the restriction of the direction in which the water droplets are ejected from the flexible tube 5. The extended length L is typically 3cm, up to 5 cm;

for the fixture to wrap attachment, FIG. 5 shows the attachment. The fixing structure comprises a fixing base plate 10, and the fixing base plate 10 is fixedly connected with the wrapping layer 6; a support 11 is arranged on the fixed base, and the support 11 is optionally a telescopic structure; the top end of the support base 11 is provided with a clamp 7 for connecting with a plant iron root or the like, and optionally, the clamp can be connected with a plant branch or the like. For the fixing requirement with the root, a plurality of fixing structures can be arranged around the wrapping layer 6, so as to form a plurality of clamps 7, so as to be convenient for connecting and fixing with the root under various environments.

In addition, a root sensor 9 may be provided on the front end face 8 of the flexible tube 5 for monitoring the water quantity or humidity.

In order to bring the irrigation as close to the root as possible in the prior art, the flexible pipe itself is provided with a clamp. Thereby play through anchor clamps and root centre gripping and make the flexible tube be close to the root region together, make the root can make full use of with the fixed water in the irrigation drip of flexible tube front end. But has problems in that: the fixture mounting surface provided to sufficiently absorb moisture can be only the side surface of the hose (the end surface is provided with a space for installing the irrigation drip and the pressure control valve). This causes difficulty in mounting and fixing. After the double-layer structure of the sleeve wrapping layer is adopted, the clamp can be fixedly arranged at the end part of the sleeve wrapping layer. After the clamp and the root are clamped and fixed, the position adjustment of the flexible pipe wrapped by the clamp in the soil is not influenced, so that the position of the flexible pipe protruding out of the wrapping layer of the sleeve can be further adjusted according to the requirement, and the requirement of various root areas for absorbing water level is met. This is also one of the points of the present invention.

Example 3

In this embodiment, the same intelligent irrigation system as in embodiments 1-2 is also employed, the intelligent irrigation system comprising a meteorological satellite 1, a processor 2, a sensor system 3, and a pressure control valve 4; wherein the sensor system 3 comprises: a temperature sensor, an air humidity sensor, a soil humidity sensor, an illumination sensor and a PIR sensor; the same in the system as in example 1 is not repeated.

In this embodiment, the receiver system of the processor 2 queries the meteorological satellite 1 for meteorological forecast data for a future period of time in the region of its gateway address; preparing an irrigation plan in a future period of time according to data including meteorological forecast data in the future period of time; the processor 2 irrigates according to the plan, and the processor 2 sends the monitored data such as meteorological data, environmental data, hydrological parameters, soil parameters and the like and the specific operation of irrigation to the user terminal through the network every day, and the user can inquire through related applications.

Example 4

This embodiment is a further improvement over embodiments 1-3, and the same parts as embodiments 1-3 will not be described again here.

The intelligent system is provided with a plurality of different types of sensors, including but not limited to a temperature sensor, an air humidity sensor, a soil humidity sensor and a light sensor; in some embodiments, these sensors may be mounted on a double-layer water delivery pipe. In some embodiments, these sensors are mounted partially on the double-layered water transport pipe and partially not on the double-layered water transport pipe. Because of the needs that double-deck water delivery pipe irrigates to the root, this double-deck water delivery pipe need set up in the root position of difference to change along with time.

For example, in A, B, C, three locations, such as 8:00-9:00 am, the roots at location A need to be monitored, including but not limited to soil moisture, soil temperature, etc. near location A; during the period of irrigation at 13:00-14:00 noon, the roots at position a and the roots at position B need to be monitored; the roots at position A, B, C need to be monitored at 18:00-19:00 pm. I.e. soil near the roots after irrigation watering of different roots at possibly different physical locations, needs to be monitored even on the same day. On the same day, the double-layer water delivery pipe needs to be frequently changed in position. This poses a challenge to the accuracy of the detection values of the various sensors located on the double-layer water delivery pipe. The temperature sensor, the air humidity sensor, the soil humidity sensor and the illumination sensor which can be attached to the double-layer water delivery pipe can measure numerical values at different positions. This is disadvantageous for large data processing. In particular, these locations do not have records in the database, resulting in incomplete records.

One solution of this embodiment is that a position sensor, such as a PIR sensor, is respectively disposed beside the temperature sensor and the soil humidity sensor of the double-layer water delivery pipe, and the PIR sensor can sense motion and can sense a specific motion direction, so as to conveniently obtain whether the double-layer water delivery pipe moves and a moving direction.

The double-layer water delivery pipe described in the embodiment 3 of the invention is used for irrigating the roots of crops, and the irrigation and watering scheme is set for meeting the requirements of cross planting of various crops and accurate control of water delivery quantity. Therefore, a need exists for a root irrigation watering post-monitoring system that is compatible therewith. After the root is irrigated, the soil environment of different areas of the root in different time periods needs to be researched so as to comprehensively evaluate the water delivery effect. If a sensing mechanism is arranged for each root, the arrangement consumes more sensors, and most of the time periods, only one sensor is used, and the sensors at other positions are in idle periods. Therefore, the invention adopts the technical scheme that a plurality of roots multiplex a set of sensors. Namely, a double-layer water delivery pipe is adopted, and a set of sensors are arranged on the double-layer water delivery pipe and used for monitoring a plurality of roots. For recording that a certain time or a certain period of time is monitoring a certain root position, it is necessary to arrange a position sensor, e.g. a PIR sensor, which records its specific position during a certain period of time, so that during monitoring the monitored value of the monitoring sensor next to (near) the PIR sensor carries position information, which is transmitted together to the processor 2. Of course, the double-layer water delivery pipe may monitor parameter information from different roots during the same time period.

Fig. 6-a to 6-c represent the detection of the position of three different time segments A, B, C, respectively. A. B, C the three locations may be the same root location and may be the location A closest to the root tip where water is most absorbed, B slightly further away, and C furthest from the root tip where water is least absorbed. FIG. 6-a shows the monitoring at time t1, A. FIG. 6-B shows monitoring at time t2, A and B, and FIG. 6-C shows monitoring at times A, B and C at t 3. Generally, t1< t2< t 3. According to the irrigation condition, the flexible pipe 5 and the wrapping layer 6 on the flexible pipe form a double-layer water conveying pipe, and a soil humidity sensor 12-1 is arranged on the wrapping layer 6; a PIR sensor 13-1 is further provided in the vicinity thereof. When the position of the double-layer water delivery pipe changes, the PIR sensor 13-1 can record the changed position; so that changes in the position of soil moisture sensor 12-1 in its vicinity can be recorded. The PIR sensor 13-1 uploads the monitored position information of any sensor after change. Similarly, the PIR sensor 13-2 monitors the change in position of its additional soil moisture sensor 12-2. The PIR sensor 13-3 monitors the position change of its additional soil moisture sensor 12-3

The soil moisture sensor may also be of the type that monitors other parameters, such as temperature sensors, root tensile stress sensors, etc. Or an air humidity sensor, a light intensity sensor and the like when the double-layer water delivery pipe is laid on the surface of soil; one of the above sensors may be used, or a plurality of sensors including several types of the above sensors may be used. The fixing mode of each type of sensor and the wrapping layer 6 can be the existing fixing mode of each type, and the fixing mode can be a detachable fixing mode according to the requirement of monitoring the position.

While the PIR sensor is used to record changes in the monitored location, those skilled in the art will appreciate that other types of sensors may be used to record changes in the monitored location and communicate the location information to the processor along with the monitored parameter information.
