Description

Technical Field

[0001] This invention belongs to the field of evaluation and analysis technology, and in particular relates to a method and device for evaluating plant growth status based on the application of conductive materials. Background Technology

[0002] Existing technical solutions often utilize plant growth images in the process of evaluating and analyzing plant growth status. For example, the invention patent application CN201810517643.1, "A method for calculating the fertilizer adjustment parameters of greenhouse plants based on growth models," provides a similar technical solution. However, the above technical solutions cannot effectively determine the growth status of plant roots, making it difficult to accurately and effectively assess the true growth status of plants.

[0003] Therefore, there is an urgent need for a method and equipment for assessing plant growth status based on the application of conductive materials. Summary of the Invention

[0004] To achieve the objectives of this invention, the following technical solution is adopted:

[0005] Specifically, this application provides a plant growth status assessment device based on the application of conductive materials, which includes:

[0006] Conductive paste is printed onto insulating paper to obtain printed paper. The printed paper is placed in soil where plants grow. A judgment indicator circuit is used to determine whether the printed insulating paper has been damaged. When the insulating paper is damaged, the warning device of the judgment indicator circuit sends a signal.

[0007] Specifically, the conductive paste includes conductive carbon paste or conductive silver paste.

[0008] Specifically, printing conductive paste onto insulating paper includes:

[0009] Conductive paste is printed onto insulating paper using screen printing.

[0010] Furthermore, the judgment indication circuit is connected to the printing paper, and when the insulation state of the printing paper changes due to the influence of root growth, the judgment indication circuit is turned on, causing the warning device of the indication circuit to issue a signal.

[0011] Specifically, the judgment indication circuit includes at least a power supply, an alarm device, and conductive lines, wherein the conductive lines are connected to the printing paper. Specifically, apart from the conductive lines connected to the printing paper, the remaining judgment indication circuit is located outside the soil.

[0012] It should be noted that the warning device is constructed using a device including a light-emitting diode that can emit a signal when determining that the indicator circuit is in a conducting state.

[0013] Secondly, this application provides a method for assessing plant growth status based on the application of conductive materials, specifically including:

[0014] S1 determines the damage duration of the printing paper of the monitoring target based on the growth stage corresponding to the plant type of the monitoring target, and determines the monitoring targets that need to be set up with backup switching circuits based on the damage duration, and uses them as optimized monitoring targets.

[0015] S2 determines the switching control strategy from the judgment indication circuit to the backup switching circuit based on the signal monitoring results of the alarm device of the judgment indication circuit of the optimized monitoring target.

[0016] S3 uses the switching control strategy to perform the switching process of the judgment indication circuit to obtain the identification processing result, and determines whether the printing method of the printing paper needs to be improved based on the identification processing result.

[0017] Furthermore, the growth stages include seed germination, seedling growth, vegetative growth, flowering and fruiting, and senescence and death.

[0018] Furthermore, the duration of damage to the insulating paper of the monitored target is determined based on the plant type corresponding to the monitored target, starting from the growth stage, and the duration of the alarm signal issued after the insulation of the printed paper is damaged.

[0019] Furthermore, the method for determining the optimized monitoring target among the monitoring targets is as follows:

[0020] Based on the duration of damage to printed paper of the plant type corresponding to the monitoring target in the same greenhouse environment, the duration of damage to different plants of the plant type corresponding to the monitoring target in history is determined.

[0021] Based on the duration of damage to different plants in the plant types corresponding to the monitored targets, the average duration of damage is determined;

[0022] The average duration of the disruption is used to determine whether the monitoring target is an optimized monitoring target.

[0023] Furthermore, determining whether the printing method of the printing paper needs improvement includes:

[0024] Based on the identification and processing results, a judgment indication circuit that is unable to send a signal normally due to a malfunction is identified and identified as a faulty circuit. Based on the number of faulty circuits, the abnormality probability of the judgment indication circuit is determined.

[0025] Based on the identification and processing results, the mean duration of damage to the optimized monitoring target in different combinations is determined. Based on the fault monitoring time data of the fault circuit, the duration from the completion of the setting to the fault monitoring time of the fault circuit is determined and taken as the fault duration. The mean duration of the faults of different fault circuits is taken as the mean duration of the fault. Based on the mean duration of the fault, combinations with a mean duration of the fault less than the mean duration of damage to the optimized monitoring target are determined and taken as poor monitoring combinations.

[0026] Based on the poor monitoring data and the abnormal probability of the judgment indicator circuit, it is determined whether the printing method of the printing paper needs to be improved.

[0027] The beneficial effects of this invention are as follows:

[0028] By printing conductive paste on insulating paper and setting up targeted judgment and indication circuits, the growth status of plant roots can be monitored conveniently and quickly. This avoids the technical problem of the original inability to effectively monitor the growth status of roots, which led to poor reliability of plant growth status assessment and analysis. This lays the foundation for further improving the reliability of plant growth monitoring.

[0029] By judging the switching results of the indicator circuit, it is determined whether the printing method of the printing paper needs to be improved. This avoids the technical problem of not being able to effectively monitor the growth status of plant roots when the indicator circuit has a high risk of failure and the plant roots have been damaging the printing paper for too long. By making targeted improvements to the printing method, the reliability of the monitoring of plant growth status is further guaranteed.

[0030] Other features and advantages will be set forth in the following description, and the objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0037] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0038] Example 1 Figure 1 As shown, this application provides a plant growth status assessment device based on the application of conductive materials, specifically including:

[0039] Conductive paste is printed onto insulating paper to obtain printed paper. The printed paper is placed in soil where plants grow. A judgment indicator circuit is used to determine whether the printed insulating paper has been damaged. When the insulating paper is damaged, the warning device of the judgment indicator circuit sends a signal.

[0040] Specifically, such as Figure 2 The diagram shown is a schematic of the printing paper in this application, wherein the conductive paste includes conductive carbon paste or conductive silver paste.

[0041] Specifically, printing conductive paste onto insulating paper includes:

[0042] Conductive paste is printed onto insulating paper using screen printing.

[0043] Furthermore, the judgment indication circuit is connected to the printing paper, and when the insulation state of the printing paper changes due to the influence of root growth, the judgment indication circuit is turned on, causing the warning device of the indication circuit to issue a signal.

[0044] Specifically, the judgment indication circuit includes at least a power supply, an alarm device, and conductive lines, wherein the conductive lines are connected to the printing paper. Specifically, apart from the conductive lines connected to the printing paper, the remaining judgment indication circuit is located outside the soil.

[0045] It should be noted that the warning device is constructed using a device including a light-emitting diode that can emit a signal when determining that the indicator circuit is in a conducting state.

[0046] Example 2, second aspect, such as Figure 3 As shown, this application provides a method for assessing plant growth status based on the application of conductive materials, specifically including:

[0047] S1 determines the damage duration of the printing paper of the monitoring target based on the growth stage corresponding to the plant type of the monitoring target, and determines the monitoring targets that need to be set up with backup switching circuits based on the damage duration, and uses them as optimized monitoring targets.

[0048] Furthermore, the growth stages include seed germination, seedling growth, vegetative growth, flowering and fruiting, and senescence and death.

[0049] Furthermore, the duration of damage to the insulating paper of the monitored target is determined based on the plant type corresponding to the monitored target, starting from the growth stage, and the duration of the alarm signal issued after the insulation of the printed paper is damaged.

[0050] In one possible specific embodiment, if the monitored target is currently on the second day of the seed germination stage, and the insulation of the insulating paper of the plant corresponding to the plant type of the monitored target is damaged, and the growth stage corresponding to the alarm signal is the fifth day of the vegetative growth stage, then the duration between the second day of the seed germination stage and the fifth day of the vegetative growth stage is taken as the damage duration.

[0051] Specifically, such as Figure 4 As shown, the method for determining the optimized monitoring target among the monitoring targets is as follows:

[0052] Based on the duration of damage to printed paper of the plant type corresponding to the monitoring target in the same greenhouse environment, the duration of damage to different plants of the plant type corresponding to the monitoring target in history is determined.

[0053] Based on the duration of damage to different plants in the plant types corresponding to the monitored targets, the average duration of damage is determined;

[0054] The average duration of the disruption is used to determine whether the monitoring target is an optimized monitoring target.

[0055] It should be noted that the plant type is determined based on the corresponding variety of the plant. For example, there are many varieties of wheat. Since the growth patterns of different varieties of plants may vary, they are classified into different plant types.

[0056] It is understandable that when the average duration of the damage does not meet the requirements, the damage duration is relatively long. Therefore, the indicator circuit may not be able to display normally due to the influence of the external environment, even if the printing paper is damaged. Therefore, the monitoring target is determined to be the optimized monitoring target, that is, a backup switching circuit is set for it. Once switched to the backup switching circuit, it is in the circuit state, which makes it easy to determine whether there is an abnormality in the indicator circuit.

[0057] It should be noted that the signal monitoring result of the alarm device is determined based on the plant data from which the alarm device sends the signal, and specifically, it can be determined through the identification result of the monitoring device.

[0058] Based on the signal monitoring results of the alarm device of the judgment indication circuit of the optimized monitoring target, a switching control strategy for the judgment indication circuit to the backup switching circuit is determined.

[0059] Specifically, the method for determining the switching control strategy from the indicator circuit to the backup switching circuit is as follows:

[0060] The same type of plant is grouped into the same group for optimized monitoring targets. Based on the signal monitoring results of the alarm device of the judgment indication circuit of the optimized monitoring target in the group, the optimized monitoring target that emits a signal from the alarm device of the judgment indication circuit in the group is determined and used as the alarm target.

[0061] The time when the alarm device of the judgment and indication circuit of the alarm target sends a signal is taken as the alarm time, and the interval between the alarm time and the current time is determined based on the alarm time.

[0062] Based on the alarm targets with an interval duration greater than a preset interval duration threshold and the total number of all alarm targets, the switching control strategy for the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined.

[0063] Specifically, when there is no alarm target in the combination, it is not possible to quickly determine whether the judgment indication circuit is working properly. Therefore, based on this, the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined by the first time period. That is, the judgment indication circuit of the optimized monitoring target in the combination is switched to the backup switching circuit every first time period.

[0064] Furthermore, when there are alarm targets in the combination, if the total number is greater than the preset alarm target number threshold, the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined to be no switching process required. If the total number is not greater than the preset alarm target number threshold, the second time period is used to determine the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit.

[0065] Furthermore, the identification processing result includes judgment indication circuit data indicating that the signal cannot be emitted normally due to a malfunction.

[0066] The switching control strategy is used to perform the switching process of the judgment indication circuit to obtain the recognition processing result. Based on the recognition processing result, it is determined whether the printing method of the printing paper needs to be improved.

[0067] Specifically, determining whether the printing method of the printing paper needs improvement includes:

[0068] Based on the identification and processing results, a judgment indication circuit that is unable to send a signal normally due to a malfunction is identified and identified as a faulty circuit. Based on the number of faulty circuits, the abnormality probability of the judgment indication circuit is determined.

[0069] Based on the identification and processing results, the mean duration of damage to the optimized monitoring target in different combinations is determined. Based on the fault monitoring time data of the fault circuit, the duration from the completion of the setting to the fault monitoring time of the fault circuit is determined and taken as the fault duration. The mean duration of the faults of different fault circuits is taken as the mean duration of the fault. Based on the mean duration of the fault, combinations with a mean duration of the fault less than the mean duration of damage to the optimized monitoring target are determined and taken as poor monitoring combinations.

[0070] Based on the poor monitoring data and the abnormal probability of the judgment indicator circuit, it is determined whether the printing method of the printing paper needs to be improved.

[0071] Specifically, the abnormal probability of the judgment indicator circuit is determined based on the proportion of the fault circuit in the judgment indicator circuit of the optimized monitoring target.

[0072] It should be noted that when the abnormal probability is less than the preset abnormal probability threshold, the probability of the indicator circuit malfunctioning is relatively small. Therefore, even if the damage lasts for a long time, it can still be effectively monitored. Thus, it is determined that the printing method of the printing paper does not need to be improved.

[0073] Furthermore, when the anomaly probability is not less than a preset anomaly probability threshold, if there is no poorly monitored combination, then it is determined that the printing method of the printing paper does not require improvement processing.

[0074] It is also understandable that if there are multiple poorly monitored combinations, then the printing method of the printing paper needs to be improved.

[0075] In one possible specific embodiment:

[0076] When the average duration of the damage is greater than 0.5 times the total duration of the plant's entire growth cycle, the monitoring target is determined to be an optimized monitoring target, that is, a backup switching circuit is set for it. Once switched to the backup switching circuit, it is in a closed state, which makes it easy to determine whether there is an abnormality in the indicator circuit.

[0077] When there are no alarm targets in the combination, the switching control strategy from the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined using a first time period. If the total number is greater than 20, the switching control strategy from the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined to be no switching process required. If the total number is not greater than the preset alarm target number threshold, the switching control strategy from the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined using a second time period.

[0078] When the anomaly probability is less than 0.01, it is determined that the printing method of the printing paper does not need to be improved. When the anomaly probability is not less than 0.01, if there are multiple poor monitoring combinations, it is determined that the printing method of the printing paper needs to be improved.

[0079] Example 3 Specifically, the method for determining the optimized monitoring target among the monitoring targets is as follows:

[0080] Based on the duration of damage to printed paper of the plant type corresponding to the monitoring target in the same greenhouse environment, the duration of damage to different plants of the plant type corresponding to the monitoring target in history is determined.

[0081] Based on the duration of damage to different plants in the plant types corresponding to the monitoring targets, plants whose duration of damage does not meet the requirements are identified;

[0082] By using the composition data of plants whose damage duration does not meet the requirements among the plant types corresponding to the monitoring target, it is determined whether the monitoring target is an optimized monitoring target.

[0083] In one possible embodiment, the plant whose destruction duration does not meet the requirement is a plant whose destruction duration is greater than a preset duration threshold. The destruction duration threshold is determined based on the total duration of the plant's entire growth cycle. The longer the total duration of the plant's entire growth cycle, the longer the preset duration threshold. In one possible embodiment, it can be determined by multiplying a preset proportional coefficient by the total duration of the plant's entire growth cycle. Specifically, the preset proportional coefficient can be set to 0.5.

[0084] Specifically, by utilizing the composition data of plants whose damage duration does not meet the requirements within the plant type corresponding to the monitoring target, it is determined whether the monitoring target is an optimized monitoring target, which specifically includes:

[0085] If the proportion of plants whose damage duration does not meet the requirements in the plant type corresponding to the monitoring target is above a preset proportion threshold, for example, above 0.2, then the monitoring target is determined to be an optimized monitoring target.

[0086] In further embodiment 4, the method for determining the switching control strategy from the indicator circuit to the backup switching circuit is as follows:

[0087] The same type of plant is grouped into the same group for optimized monitoring targets. Based on the signal monitoring results of the alarm device of the judgment indication circuit of the optimized monitoring target in the group, the optimized monitoring target that emits a signal from the alarm device of the judgment indication circuit in the group is determined and used as the alarm target.

[0088] It is understandable that when there is no alarm target in the combination, it is not possible to quickly determine whether the judgment indication circuit is working properly. Therefore, based on this, the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined by the first time period. That is, the judgment indication circuit of the optimized monitoring target in the combination is switched to the backup switching circuit every first time period.

[0089] By using the first time period for switching control processing in the above steps, the working state of the judgment indicator circuit can be determined, thereby avoiding the situation where the judgment indicator circuit cannot effectively display the true plant growth status even if the insulation state of the printing paper changes, thus improving the reliability of the monitoring and processing of plant growth status.

[0090] It should be noted that if there are alarm targets in the combination, the composition data of the alarm targets in the combination is determined. When the number of alarm targets in the combination meets the requirements, there are a large number of alarm targets. Since the growth environment is the same, it can be roughly judged that other plants in the combination are also likely to issue alarm signals soon. Therefore, based on this, the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined to be no switching process, thereby ensuring the operational stability of the judgment indication circuit.

[0091] The alarm time is defined as the moment when the alarm device of the judgment and indication circuit of the alarm target issues a signal.

[0092] It should be noted that, in the above steps, based on the alarm times of different alarm targets, the interval between the alarm times of different alarm targets and the current time is determined. When the number of alarm targets with an interval length greater than a preset interval length threshold is greater than a preset target number threshold, it can still be roughly judged that other plants in the combination may also issue alarm signals soon. Therefore, based on this, the switching control strategy for the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined to be no switching process required, thereby ensuring the operational stability of the judgment indication circuit.

[0093] In the above steps, by combining the alarm time of the alarm target with the interval between the current time, the probability of the insulation state of the printed paper of the optimized monitoring target in the future time period is assessed. In this way, when the probability of damage is high, the frequent switching to the backup switching circuit is avoided, which leads to the technical problem of poor reliability of the judgment and indication circuit. This ensures the working stability of the judgment and indication circuit.

[0094] Based on the alarm target data in the combination and the alarm times of different alarm targets, determine the switching control strategy from the judgment indication circuit to the backup switching circuit in the combination.

[0095] Specifically, based on the alarm target data in the combination and the alarm times of different alarm targets, the switching control strategy for the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined, specifically including:

[0096] Based on the interval between the alarm time of different alarm targets and the current time, alarm targets with an interval length greater than a preset interval length threshold are identified.

[0097] Based on the interval duration being greater than a preset interval duration threshold, such as the total number of alarm targets in one week and all alarm targets, if the total number is greater than a preset alarm target number threshold, then the switching control strategy for the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit is determined to be no switching process required. If the total number is not greater than the preset alarm target number threshold, then the second time period is used to determine the switching control strategy for the judgment indication circuit of the optimized monitoring target in the combination to the backup switching circuit.

[0098] It is understood that the first time period is shorter than the second time period. In one possible embodiment, the first time period is 3 days and the second time period is 5 days.

[0099] Example 5 further involves determining whether the printing method of the printing paper needs improvement, specifically including:

[0100] Based on the identification and processing results, a judgment and indication circuit that is unable to send signals normally due to a malfunction is identified and designated as a faulty circuit.

[0101] It should be noted that if the number of faulty circuits is within the specified range in the above steps, the probability of the indicator circuit failing is relatively low. Therefore, even if the damage lasts for a long time, effective monitoring can still be achieved, thus determining that the printing method of the printing paper does not require improvement.

[0102] In this application, by judging the number of faulty circuits, the technical problem of poor reliability in monitoring plant growth status is avoided, which is caused by judging that the operating status of the indicator circuit is not good and therefore not improving the printing method of the printing paper, such as reducing the insulation resistance or increasing the printing width of the conductive paste. This improves the reliability of monitoring and processing plant growth status.

[0103] Based on the identification and processing results, the mean duration of destruction of the optimized monitoring target in different combinations is determined;

[0104] Based on the fault monitoring time data of the fault circuit and the average duration of damage to the optimized monitoring target in different combinations, it is determined whether the printing method of the printing paper needs to be improved.

[0105] Furthermore, based on the fault monitoring time data of the faulty circuit and the average duration of damage to the optimized monitoring target in different combinations, it is determined whether the printing method of the printing paper needs to be improved, specifically including:

[0106] Based on the fault monitoring time data of the fault circuit, the duration from the completion of the setting to the fault monitoring time of the fault circuit is determined and used as the fault duration. The average fault duration of different fault circuits is used as the average fault duration.

[0107] Based on the average fault duration, combinations whose average fault duration is less than the average damage duration of the optimized monitoring target are identified and treated as poor monitoring combinations.

[0108] Based on the poorly monitored combination of data, it is determined whether the printing method of the printing paper needs to be improved.

[0109] It is understandable that when multiple poor monitoring combinations exist, it is determined that the printing method of the printing paper needs to be improved.
