Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to an environmental monitoring system for rapeseed planting. Background Art

[0002] In the prior art, rapeseed, as an important oil crop, is significantly affected by a variety of environmental factors in its yield and quality. In the traditional rapeseed planting process, growers often rely on experience and regular manual inspections to determine whether the planting environment is suitable. However, this method has many limitations and is difficult to meet the needs of modern precision agriculture for real-time and accurate environmental information. With the continuous development of sensor technology, various environmental sensors have gradually been applied to the agricultural field, providing the possibility of achieving accurate environmental monitoring.

[0003] Chinese Patent Publication No.: CN110262364A discloses an Internet-based agricultural planting environment monitoring device, including an image acquisition unit, an image analysis unit, a spray device and a server; the image acquisition unit and the spray device are connected to the server through cables, and the image analysis unit runs on the server; the image acquisition unit is used to take and store photos of fruit trees; the image analysis unit is used to analyze the distribution of insects on leaves according to the photos taken by the image acquisition unit; the spray device is used to spray pesticides and kill pests according to the results of the image analysis unit analysis; through the cooperation between the image acquisition unit, the image analysis unit and the spray device, the development of fruit tree diseases and pests is detected in real time, pests are discovered and eliminated early, and the healthy growth of fruit trees is guaranteed. It can be seen that the Internet-based agricultural planting environment monitoring device has the problem that the fertilizer splashes onto the surface of the soil moisture sensor, causing the shell to be corroded, the accuracy of the sensor to decrease, and thus the stability of the environmental monitoring of rapeseed planting is reduced. Summary of the invention

[0004] To this end, the present invention provides an environmental monitoring system for rapeseed cultivation, which is used to overcome the problem in the prior art that fertilizer splashes onto the surface of the soil moisture sensor, causing the shell to be corroded, the accuracy of the sensor to be reduced, and thus the stability of the environmental monitoring of rapeseed cultivation to be reduced.

[0005] To achieve the above-mentioned purpose, the present invention provides an environment monitoring system for rapeseed planting, comprising: a data acquisition module for collecting environmental data for rapeseed planting, including a soil moisture sensor for collecting soil moisture for rapeseed planting, a temperature sensor for detecting environmental temperature, and a water quality sensor for detecting irrigation water quality; a communication module, which is connected to the data acquisition module, including an analysis unit for analyzing the environmental data to output an analysis result and a data transmission unit connected to the analysis unit for transmitting the environmental data and the analysis result to a display interface respectively; a storage module, which is respectively connected to the data acquisition module and the communication module, and is respectively used to store the environmental data and the analysis result; a power supply module, which is respectively connected to the data acquisition module, the communication module, and the storage module, and is used to supply power; a control module, which is respectively connected to the data acquisition module, the communication module, the storage module, and the power supply module, and is used to determine the sampling frequency of the soil moisture sensor according to the fluctuation amplitude of the soil moisture for rapeseed planting, or, to determine the cache capacity of the environmental data according to the average packet loss rate of the environmental data, and, to determine the discharge mode of the battery according to the proportion of the time of battery power supply per unit time.

[0006] Furthermore, the control module is used to determine whether the environmental monitoring stability of rapeseed planting meets the requirements based on the fluctuation amplitude of the humidity of the rapeseed planting land. If the fluctuation amplitude of the humidity of the rapeseed planting land is greater than a preset first fluctuation amplitude, it is determined that the environmental monitoring stability of rapeseed planting does not meet the requirements.

[0007] Furthermore, when the fluctuation amplitude of the humidity of the rapeseed-growing land is greater than the preset first fluctuation amplitude and less than or equal to the preset second fluctuation amplitude, the control module preliminarily determines that the functional execution continuity of the environmental monitoring system does not meet the requirements, and determines whether the functional execution continuity of the environmental monitoring system meets the requirements based on the average packet loss rate of the environmental data.

[0008] Furthermore, the control module increases the sampling frequency of the soil moisture sensor when the fluctuation amplitude of the moisture of the rapeseed planting land is greater than the preset second fluctuation amplitude;

[0009] The increase range of the sampling frequency of the soil moisture sensor is determined by the difference between the fluctuation range of the moisture of the rapeseed-planting land and a preset second fluctuation range.

[0010] Furthermore, the control module is used to determine whether the functional execution continuity of the environmental monitoring system meets the requirements based on the average packet loss rate of the environmental data. If the average packet loss rate of the environmental data is greater than the preset first packet loss rate, it is determined that the functional execution continuity of the environmental monitoring system does not meet the requirements.

[0011] Furthermore, when the average packet loss rate of the environmental data is greater than a preset second packet loss rate, the control module preliminarily determines that the power supply stability of the environmental monitoring system does not meet the requirements, and determines whether the power supply stability of the environmental monitoring system meets the requirements based on the proportion of battery power supply time per unit time.

[0012] Furthermore, the control module increases the cache capacity of the environmental data when the average packet loss rate of the environmental data is greater than the preset first packet loss rate and less than or equal to the preset second packet loss rate.

[0013] Furthermore, the increase range of the cache capacity of the environmental data is determined by the difference between the average packet loss rate of the environmental data and a preset first packet loss rate.

[0014] Furthermore, the control module is used to determine whether the power supply stability of the environmental monitoring system meets the requirements based on the proportion of battery-powered time in a unit time. If the proportion of battery-powered time in the unit time is greater than a preset proportion, it is determined that the power supply stability of the environmental monitoring system does not meet the requirements, and the battery discharge mode is switched.

[0015] Furthermore, the discharge mode of the battery is switched from high-power discharge to low-power discharge.

[0016] Compared with the prior art, the beneficial effect of the present invention lies in that the system of the present invention determines the sampling frequency of the soil moisture sensor according to the fluctuation amplitude of the moisture of the rapeseed planting land by setting a data acquisition module, a communication module, a storage module, a power supply module and a control module. Since fertilizer splashes onto the surface of the soil moisture sensor during fertilization of rapeseed, causing the outer shell to be corroded, thereby affecting the accuracy of the sensor, by increasing the sampling frequency of the soil moisture sensor, the dynamic changes of soil moisture can be captured more finely, and the instantaneous changes of soil moisture caused by fertilization can be recorded more accurately. The cache capacity of environmental data is determined according to the average packet loss rate of environmental data. Since in rainy or windy weather, the sampling frequency of the soil moisture sensor is increased, the dynamic changes of soil moisture can be captured more finely, and the instantaneous changes of soil moisture caused by fertilization can be recorded more accurately. The cache capacity of environmental data is determined according to the average packet loss rate of environmental data. When the sensor is in a rainy state, raindrops absorb and scatter electromagnetic waves, causing the signal detected by the sensor to attenuate, thereby causing some sensor data to be lost. By increasing the cache capacity of the sensor data, more data can be stored so that it can be retransmitted at the right time to reduce the impact of data loss. The battery discharge mode is determined according to the proportion of battery power supply time per unit time. Since the insulation layer of the wire used to connect the battery and the sensor is worn, the internal wire short-circuit occurs, resulting in unstable power supply. By switching the battery discharge mode, the effective power supply time of the battery can be extended, which helps to maintain relatively stable operation of the system under unstable power supply conditions and improves the stability of environmental monitoring of rapeseed planting.

[0017] Furthermore, the system of the present invention determines the sampling frequency of the soil moisture sensor by setting a preset first fluctuation amplitude and a preset second fluctuation amplitude. During the process of fertilizing rapeseed, fertilizer splashes onto the surface of the soil moisture sensor, causing the outer shell to be corroded, thereby affecting the accuracy of the sensor. By increasing the sampling frequency of the soil moisture sensor, the dynamic changes of soil moisture can be captured more finely, and the instantaneous changes in soil moisture caused by fertilization can be recorded more accurately, thereby further improving the stability of environmental monitoring of rapeseed planting.

[0018] Furthermore, the system of the present invention determines the cache capacity of environmental data by setting a preset first packet loss rate and a preset second packet loss rate. Because raindrops absorb and scatter electromagnetic waves in rainy or windy weather, the signal detected by the sensor is attenuated, thereby causing part of the sensor data to be lost. By increasing the cache capacity of the sensor data, more data can be stored for retransmission at the appropriate time, reducing the impact of data loss and further improving the stability of environmental monitoring of rapeseed planting.

[0019] Furthermore, the system of the present invention determines the discharge mode of the battery by setting a preset ratio. Since the insulation layer of the wire used to connect the battery and the sensor is worn, the internal wire short-circuit occurs, resulting in unstable power supply. By switching the discharge mode of the battery, the effective power supply time of the battery can be extended, which helps to maintain relatively stable operation of the system under unstable power supply conditions, further improving the stability of environmental monitoring of rapeseed planting.

[0028] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, they are respectively an overall structural block diagram, a logic flow chart, a specific structural block diagram of a data acquisition module, and a specific structural block diagram of a communication module of an environmental monitoring system for rapeseed planting according to an embodiment of the present invention. An environmental monitoring system for rapeseed planting according to the present invention comprises:

[0029] A data acquisition module, for collecting environmental data of rapeseed planting, including a soil moisture sensor for collecting soil moisture of rapeseed planting, a temperature sensor for detecting ambient temperature, and a water quality sensor for detecting irrigation water quality;

[0030] a communication module connected to the data acquisition module, comprising an analysis unit for analyzing the environmental data to output an analysis result and a data transmission unit connected to the analysis unit for transmitting the environmental data and the analysis result to a display interface respectively;

[0031] A storage module, which is connected to the data acquisition module and the communication module respectively, and is used to store the environmental data and the analysis results respectively;

[0032] A power supply module, which is respectively connected to the data acquisition module, the communication module and the storage module for power supply;

[0033] A control module is respectively connected to the data acquisition module, the communication module, the storage module and the power supply module, and is used to determine the sampling frequency of the soil moisture sensor according to the fluctuation amplitude of the humidity of the rapeseed planting land, or to determine the cache capacity of the environmental data according to the average packet loss rate of the environmental data, and to determine the discharge mode of the battery according to the proportion of the battery power supply time per unit time.

[0034] Specifically, the environmental data include the humidity of the rapeseed planting land, the ambient temperature of rapeseed planting, and the ambient humidity of rapeseed planting.

[0035] Specifically, the data acquisition module also includes:

[0036] A light sensor for detecting light intensity;

[0037] Humidity sensor is used to detect the air humidity in the environment.

[0038] Specifically, the analysis results include irrigation recommendations for rapeseed planting, fertilization recommendations for rapeseed planting, and growth trend analysis of rapeseed.

[0039] In practice, the system of the present invention determines the sampling frequency of the soil moisture sensor according to the fluctuation amplitude of the moisture of the rapeseed planting land by setting a data acquisition module, a communication module, a storage module, a power supply module and a control module. During the process of fertilizing rapeseed, fertilizer splashes onto the surface of the soil moisture sensor, causing the outer shell to be corroded, thereby affecting the accuracy of the sensor. By increasing the sampling frequency of the soil moisture sensor, the dynamic changes of soil moisture can be captured more finely, and the instantaneous changes of soil moisture caused by fertilization can be recorded more accurately. The cache capacity of environmental data is determined according to the average packet loss rate of environmental data. In rainy or windy weather, raindrops have a great impact on the electromagnetic field. Waves have absorption and scattering effects, causing the signals detected by the sensor to attenuate, thereby causing some sensor data to be lost. By increasing the cache capacity of sensor data, more data can be stored so that it can be retransmitted at the right time to reduce the impact of data loss. The battery discharge mode is determined according to the proportion of battery power supply time per unit time. Since the insulation layer of the wire used to connect the battery and the sensor is worn, the internal wire short-circuit occurs, resulting in unstable power supply. By switching the battery discharge mode, the effective power supply time of the battery can be extended, which helps to maintain the relatively stable operation of the system under unstable power supply conditions and improves the stability of environmental monitoring of rapeseed planting.

[0040] Specifically, the control module is used to obtain the humidity of rapeseed-planting land per unit time and calculate the fluctuation amplitude of the humidity of rapeseed-planting land. If the fluctuation amplitude of the humidity of the rapeseed-planting land is greater than the preset first fluctuation amplitude, it is determined that the environmental monitoring stability of rapeseed planting does not meet the requirements.

[0041] Specifically, when the fluctuation amplitude of the humidity of the rapeseed-growing land is greater than the preset first fluctuation amplitude and less than or equal to the preset second fluctuation amplitude, the control module preliminarily determines that the functional execution continuity of the environmental monitoring system does not meet the requirements, and determines whether the functional execution continuity of the environmental monitoring system meets the requirements based on the average packet loss rate of the environmental data.

[0042] It can be understood that the three intervals corresponding to the preset first fluctuation range and the preset second fluctuation range correspond to three situations respectively:

[0043] The first interval is that the fluctuation range of the soil humidity of rapeseed planting land is less than or equal to the preset first fluctuation range, and the corresponding situation is: the stability of environmental monitoring of rapeseed planting meets the requirements;

[0044] The second interval is when the fluctuation amplitude of the humidity of the rapeseed planting land is greater than the preset first fluctuation amplitude and less than or equal to the preset second fluctuation amplitude. The corresponding situation is: in rainy or windy weather, raindrops absorb and scatter electromagnetic waves, causing the signal detected by the sensor to attenuate, thereby causing part of the sensor data to be lost;

[0045] The third interval is when the fluctuation amplitude of the humidity of the rapeseed-growing land is greater than the preset second fluctuation amplitude. The corresponding situation is: during the process of fertilizing rapeseed, the fertilizer splashes onto the surface of the soil moisture sensor, causing the outer shell to be corroded, thereby affecting the accuracy of the sensor.

[0046] In practice, the preset first fluctuation range is generally selected in the range of [30%, 40%], and the preset second fluctuation range is generally selected in the range of [41%, 51%].

[0047] Preferably, the preferred embodiment of the preset first fluctuation amplitude is 35%, and the preferred embodiment of the preset second fluctuation amplitude is 40%.

[0048] Specifically, the unit of fluctuation range of moisture in rapeseed-growing land is relative moisture content, and the meaning of relative moisture content is the percentage of actual soil moisture content to field water holding capacity.

[0049] Specifically, the fluctuation range of the humidity of the rapeseed-growing land is the difference between the maximum humidity of the rapeseed-growing land and the minimum humidity of the rapeseed-growing land within a unit time.

[0050] In implementation, the system of the present invention determines the stability of environmental monitoring of rapeseed planting by setting a preset first fluctuation amplitude and a preset second fluctuation amplitude, thereby reducing the impact of decreased accuracy of environmental monitoring of rapeseed planting due to inaccurate determination of the stability of environmental monitoring of rapeseed planting, and further improving the stability of environmental monitoring of rapeseed planting.

[0051] Specifically, the control module increases the sampling frequency of the soil moisture sensor when the fluctuation amplitude of the moisture of the rapeseed planting land is greater than the preset second fluctuation amplitude;

[0052] The increase range of the sampling frequency of the soil moisture sensor is determined by the difference between the fluctuation range of the moisture of the rapeseed-planting land and a preset second fluctuation range.

[0053] Specifically, when the difference between the fluctuation amplitude of the humidity of the rapeseed planting land and the preset second fluctuation amplitude is within 10%, the sampling frequency of the soil moisture sensor is increased to 1.2 times of the original; when the difference between the fluctuation amplitude of the humidity of the rapeseed planting land and the preset second fluctuation amplitude exceeds 10%, on the basis of increasing to 1.2 times of the original, the sampling frequency of the soil moisture sensor is increased by 1 time / day for every 5% exceeding it. For example, the difference between the fluctuation amplitude of the humidity of the rapeseed planting land and the preset second fluctuation amplitude is 20%. The current sampling frequency of the soil moisture sensor is 5 times / day, and the increased sampling frequency of the soil moisture sensor is 5×1.2+1×2=8 times / day.

[0054] In implementation, the system of the present invention determines the sampling frequency of the soil moisture sensor by setting a preset first fluctuation amplitude and a preset second fluctuation amplitude. During the process of fertilizing rapeseed, fertilizer splashes onto the surface of the soil moisture sensor, causing the outer shell to be corroded, thereby affecting the accuracy of the sensor. By increasing the sampling frequency of the soil moisture sensor, the dynamic changes of soil moisture can be captured more finely, and the instantaneous changes in soil moisture caused by fertilization can be recorded more accurately, further improving the stability of environmental monitoring of rapeseed planting.

[0055] Specifically, the control module is used to obtain the packet loss rate of environmental data per unit time and calculate the average packet loss rate of environmental data. If the average packet loss rate of environmental data is greater than a preset first packet loss rate, it is determined that the functional execution continuity of the environmental monitoring system does not meet the requirements.

[0056] Specifically, when the average packet loss rate of the environmental data is greater than a preset second packet loss rate, the control module preliminarily determines that the power supply stability of the environmental monitoring system does not meet the requirements, and determines whether the power supply stability of the environmental monitoring system meets the requirements based on the proportion of battery power supply time per unit time.

[0057] It can be understood that the two intervals corresponding to the preset first packet loss rate and the preset second packet loss rate correspond to three situations respectively:

[0058] The first interval is when the average packet loss rate of environmental data is less than or equal to the preset first packet loss rate, and the corresponding situation is: the functional execution continuity of the environmental monitoring system meets the requirements;

[0059] The second interval is when the average packet loss rate of environmental data is greater than the preset first packet loss rate and less than or equal to the preset second packet loss rate. The corresponding situation is: in rainy or windy weather, raindrops absorb and scatter electromagnetic waves, causing the signal detected by the sensor to attenuate, thereby causing some sensor data to be lost;

[0060] The third interval is when the average packet loss rate of environmental data is greater than the preset second packet loss rate. The corresponding situation is: the insulation layer of the wire used to connect the battery and the sensor is worn, causing the internal wire to short-circuit, resulting in unstable power supply.

[0061] In practice, the preset first packet loss rate is generally selected in the range of [6%, 8%], and the preset second packet loss rate is generally selected in the range of [9%, 11%].

[0062] Preferably, the preferred embodiment of the preset first packet loss rate is 7%, and the preferred embodiment of the preset second packet loss rate is 10%.

[0063] Specifically, the average packet loss rate of the environmental data is a ratio of the total packet loss rate of the environmental data in a number of transmission cycles to the number of transmission cycles.

[0064] In implementation, the system of the present invention determines the continuity of functional execution of the environmental monitoring system by setting a preset first packet loss rate and a preset second packet loss rate, thereby reducing the impact of decreased stability of environmental monitoring of rapeseed planting due to inaccurate determination of continuity of functional execution of the environmental monitoring system, and further improving the stability of environmental monitoring of rapeseed planting.

[0065] Specifically, the control module increases the cache capacity of the environmental data when the average packet loss rate of the environmental data is greater than the preset first packet loss rate and less than or equal to the preset second packet loss rate.

[0066] Specifically, the increase range of the cache capacity of the environmental data is determined by the difference between the average packet loss rate of the environmental data and a preset first packet loss rate.

[0067] Specifically, when the difference between the average packet loss rate of environmental data and the preset first packet loss rate is within 5%, the cache capacity of environmental data is increased to 1.1 times of the original value; when the difference between the average packet loss rate of environmental data and the preset first packet loss rate exceeds 5%, on the basis of being increased to 1.1 times of the original value, the cache capacity of environmental data is increased by 50KB for every 2% exceeding the original value. For example, the difference between the average packet loss rate of environmental data and the preset first packet loss rate is 9%, the current cache capacity of environmental data is 500KB, and the increased cache capacity of environmental data is 500×1.1+50×2=650KB.

[0068] In implementation, the system of the present invention determines the cache capacity of environmental data by setting a preset first packet loss rate and a preset second packet loss rate. Because raindrops absorb and scatter electromagnetic waves in rainy or windy weather, the signal detected by the sensor is attenuated, thereby causing part of the sensor data to be lost. By increasing the cache capacity of the sensor data, more data can be stored for retransmission at the appropriate time, reducing the impact of data loss and further improving the stability of environmental monitoring of rapeseed planting.

[0069] Specifically, the control module is used to obtain the battery power supply duration per unit time and calculate the proportion of the battery power supply time per unit time. If the proportion of the battery power supply time per unit time is greater than the preset proportion, it is determined that the power supply stability of the environmental monitoring system does not meet the requirements, and the battery discharge mode is switched.

[0070] It can be understood that the two intervals corresponding to the preset proportions correspond to two situations:

[0071] The first interval is when the battery power supply time ratio per unit time is less than or equal to the preset ratio, and the corresponding situation is: the power supply stability of the environmental monitoring system meets the requirements;

[0072] The second interval is when the battery-powered time percentage per unit time is greater than the preset percentage. The corresponding situation is: the insulation layer of the wire used to connect the battery and the sensor is worn, causing the internal wire to short-circuit, resulting in unstable power supply.

[0073] In practice, the preset ratio is generally selected in the range of [0.7, 0.9].

[0074] Preferably, the preset ratio is preferably 0.8.

[0075] Specifically, the proportion of battery power supply time per unit time is the ratio of the total battery power supply time per unit time to the duration of the battery power supply per unit time.

[0076] During implementation, the system of the present invention determines the power supply stability of the environmental monitoring system by setting a preset ratio, thereby reducing the impact of the decline in environmental monitoring stability of rapeseed planting due to inaccurate determination of the power supply stability of the environmental monitoring system, and further improving the environmental monitoring stability of rapeseed planting.

[0077] Specifically, the discharge mode of the battery is switched from high-power discharge to low-power discharge.

[0078] In implementation, the system of the present invention determines the discharge mode of the battery by setting a preset ratio. Since the insulation layer of the wire used to connect the battery and the sensor is worn, the internal wire short-circuit occurs, resulting in unstable power supply. By switching the discharge mode of the battery, the effective power supply time of the battery can be extended, which helps to maintain relatively stable operation of the system under unstable power supply conditions, further improving the stability of environmental monitoring of rapeseed planting.

[0079] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
