TECHNICAL FIELD

[0001] The application belongs to the field of evaluation analysis, and particularly relates to a plant growth state evaluation method and device based on application of conductive material. BACKGROUND

[0002] The prior art scheme often uses plant growth images in the process of evaluating and analyzing the plant growth state, for example, the similar technical scheme is given in the invention patent application CN201810517643.1 "Greenhouse plant water and fertilizer machine fertilization parameter calculation method based on growth model", but the above technical scheme cannot effectively determine the growth state of the plant root system, so it is difficult to accurately and effectively evaluate the real growth state of the plant.

[0003] Therefore, there is an urgent need for a plant growth state evaluation method and device based on application of conductive material. SUMMARY

[0004] To achieve the object of the application, the application adopts the following technical scheme: Specifically, the application provides a plant growth state evaluation device based on application of conductive material, which specifically comprises: The conductive paste is printed on the insulating paper to obtain printed paper, the printed paper is placed in the soil where the plant grows, the judgment indicating circuit is used to judge whether the printed insulating paper is damaged, and when the insulating paper is damaged, the warning device of the judgment indicating circuit is controlled to send a signal.

[0005] Specifically, the conductive paste comprises conductive carbon paste or conductive silver paste.

[0006] Specifically, the conductive paste is printed on the insulating paper, which specifically comprises: The conductive paste is printed on the insulating paper by means of silk screen printing.

[0007] Further, the judgment indicating circuit is connected to the printed paper, and when the insulating state of the printed paper changes due to the growth of the root system, the judgment indicating circuit is turned on, so that the warning device of the indicating circuit sends a signal.

[0008] Specifically, the judgment indicating circuit at least comprises a power supply, a warning device and a conductive circuit, wherein the conductive circuit is connected to the printed paper, and specifically, except for the conductive circuit connected to the printed paper, the remaining judgment indicating circuit is arranged outside the soil.

[0009] It should be noted that the warning device is constructed by using a device capable of sending a signal when the judgment indicating circuit is in the on state, including a light emitting diode.

[0010] In a second aspect, the application provides a plant growth state evaluation method based on a conductive material application, specifically comprising: S1 determines the damage duration of the printed paper of the monitoring target in the growth stage corresponding to the plant type corresponding to the monitoring target, determines the monitoring target that needs to be set with a backup switching circuit among the monitoring targets based on the damage duration, and takes it as an optimized monitoring target; S2 determines the switching control strategy of the judgment indication circuit to the backup switching circuit based on the signal monitoring result of the alarm device of the optimized monitoring target; S3 performs switching processing of the judgment indication circuit to obtain a recognition processing result, and determines whether the printing method of the printed paper needs to be improved based on the recognition processing result.

[0011] Further, the growth stage includes seed germination, seedling growth, vegetative growth, flowering and fruiting, and death.

[0012] Further, the damage duration of the insulation paper of the monitoring target is determined according to the time length of the alarm signal emitted after the insulation of the printed paper is damaged, starting from the growth stage of the plant type corresponding to the monitoring target.

[0013] Further, the method for determining the optimized monitoring target among the monitoring targets is: determining the damage duration of the printed paper of the plant type corresponding to the monitoring target in the same greenhouse environment, and determining the damage duration of different plants in the plant type corresponding to the monitoring target in history; determining the mean value of the damage duration based on the damage duration of different plants in the plant type corresponding to the monitoring target; determining whether the monitoring target is an optimized monitoring target by using the mean value of the damage duration.

[0014] Further, determining whether the printing method of the printed paper needs to be improved specifically includes: determining the judgment indication circuit that cannot normally emit a signal due to a fault based on the recognition processing result, taking it as a fault circuit, determining the abnormal probability of the judgment indication circuit based on the number of the fault circuit; determining the mean value of the damage duration of the optimized monitoring target in different combinations based on the recognition processing result, determining the duration from the completion of the setting to the fault monitoring time of the fault circuit based on the fault monitoring time data of the fault circuit, taking it as a fault duration, taking the mean value of the fault duration of different fault circuits as a fault duration mean value, and determining the combination in which the fault duration mean value is less than the mean value of the damage duration of the optimized monitoring target based on the fault duration mean value, and taking it as a poor monitoring combination. Determine whether the printing method of the printed paper needs to be improved based on the poor combination data and the abnormal probability of the judgment indication circuit.

[0015] The beneficial effects of the present application are: By printing the conductive paste on the insulating paper and setting the judgment indication circuit, the growth state of the plant root system can be monitored conveniently and quickly, avoiding the original technical problem that the growth state of the plant root system cannot be effectively monitored, resulting in poor reliability of the evaluation and analysis of the growth state of the plant, thereby laying a foundation for further improving the reliability of the growth monitoring of the plant.

[0016] Determine whether the printing method of the printed paper needs to be improved based on the recognition result of the switching process of the judgment indication circuit, thereby avoiding the technical problem that the growth state of the plant root system cannot be effectively monitored when the failure risk of the judgment indication circuit is high and the time length of the damage of the plant root system to the printed paper is too long, and further ensuring the reliability of the monitoring process of the growth state of the plant by improving the printing method.

[0017] Other features and advantages will be set forth in the following description of the application, and in part will be apparent from the description and the accompanying drawings, or can be learned by practice of the application as claimed in the claims.

DETAILED DESCRIPTION

[0021] In order for those skilled in the technical field to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in combination with the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the specification, not all. Based on the embodiments of the specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the specification.

[0022] Embodiment 1 as shown in Figure 1 The application provides a plant growth state evaluation device based on the application of conductive material, which specifically comprises: The conductive paste is printed on the insulating paper to obtain printed paper, the printed paper is placed in the soil where the plant grows, the printed insulating paper is judged whether it is damaged or not by using the judgment indicating circuit, and when the insulating paper is damaged, the warning device of the judgment indicating circuit is controlled to send a signal.

[0023] Specifically, as shown in Figure 2 The printed paper in the application is a schematic diagram, wherein the conductive paste comprises conductive carbon paste or conductive silver paste.

[0024] Specifically, the conductive paste is printed on the insulating paper, which specifically comprises: The conductive paste is printed on the insulating paper by means of silk screen printing.

[0025] Further, the judgment indicating circuit is connected to the printed paper, and when the insulating state of the printed paper changes due to the growth of the root system, the judgment indicating circuit is turned on, and the warning device of the indicating circuit sends a signal.

[0026] Specifically, the judgment indicating circuit at least comprises a power supply, a warning device and a conductive circuit, wherein the conductive circuit is connected to the printed paper, and specifically, except for the conductive circuit connected to the printed paper, the remaining judgment indicating circuit is arranged outside the soil.

[0027] It should be noted that the warning device is constructed by using a device capable of sending a signal when the judgment indicating circuit is in the on state, including a light emitting diode.

[0028] Embodiment 2, the second aspect, as shown in Figure 3 The application provides a plant growth state evaluation method based on the application of conductive material, which specifically comprises: S1 determines the damage duration of the printed paper of the monitoring target in the growth stage corresponding to the plant type corresponding to the monitoring target, determines the monitoring target which needs to be set with a standby switching circuit in the monitoring target based on the damage duration, and takes it as an optimized monitoring target; Further, the growth stages include seed germination, seedling growth, vegetative growth, flowering and fruiting, and senescence and death.

[0029] Further, the destruction time of the insulation paper of the monitoring target is determined according to the plant type corresponding to the monitoring target, and after the insulation of the insulation paper is destroyed, the time when the alarm signal is sent.

[0030] In a possible specific embodiment, if the monitoring target is currently in the second day of the seed germination stage, and after the insulation of the insulation paper of the plant of the plant type corresponding to the monitoring target is destroyed, the growth stage corresponding to the alarm signal sent is the fifth day of the vegetative growth stage, then the time between the second day of the seed germination stage and the fifth day of the vegetative growth stage is taken as the destruction time.

[0031] Specifically, as shown in Figure 4 The method for determining the optimal monitoring target in the monitoring targets is: determining the destruction time of the insulation paper of the plant type corresponding to the monitoring target in the same greenhouse environment; determining the mean value of the destruction time based on the destruction time of different plants in the plant type corresponding to the monitoring target; determining whether the monitoring target is an optimal monitoring target by using the mean value of the destruction time.

[0032] It should be noted that the plant type is determined according to the variety corresponding to the plant. For example, there are many varieties of wheat. Because the growth rules of different varieties of plants may deviate to a certain extent, they are divided into different plant types.

[0033] It can be understood that when the mean value of the destruction time does not meet the requirements, at this time, because the destruction time is relatively long, the indication circuit may be affected by the external environment during this process, and even if the insulation paper is destroyed, it cannot be normally displayed, and therefore it is determined that the monitoring target is an optimal monitoring target, that is, a standby switching circuit is set for it. Once switched to the standby switching circuit, it is in the pass-through state, which can facilitate the determination of whether the indication circuit is abnormal.

[0034] It should be noted that the signal monitoring result of the alarm device is determined according to the plant data sent by the alarm device, and specifically can be determined by the identification result of the monitoring device.

[0035] Based on the signal monitoring result of the alarm device of the indication circuit of the optimal monitoring target, a switching control strategy of the indication circuit to the standby switching circuit is determined; Specifically, the determination method of the switching control strategy of the judgment indication circuit to the backup switching circuit is: The optimization monitoring targets of the same plant type are divided into the same combination, the signal monitoring result of the alarm device of the judgment indication circuit in the optimization monitoring target in the combination is determined, the optimization monitoring target of the alarm device of the judgment indication circuit in the combination is determined as the alarm target, and the alarm target is determined as the alarm target; The time when the alarm device of the judgment indication circuit of the alarm target sends a signal is determined as the alarm time, and the interval time between the alarm time and the current time is determined based on the alarm time; Based on the total number of alarm targets with interval time greater than the preset interval time threshold and all alarm targets, the switching control strategy of the judgment indication circuit of the optimization monitoring target in the combination to the backup switching circuit is determined.

[0036] Specifically, when there is no alarm target in the combination, the switching control strategy of the judgment indication circuit of the optimization monitoring target in the combination to the backup switching circuit is determined based on the first time period, i.e. the judgment indication circuit of the optimization monitoring target in the combination is switched to the backup switching circuit every first time period.

[0037] Further, when there is an alarm target in the combination, if the total number is greater than the preset alarm target number threshold, it is determined that the switching control strategy of the judgment indication circuit of the optimization monitoring target in the combination to the backup switching circuit is unnecessary, and if the total number is not greater than the preset alarm target number threshold, the switching control strategy of the judgment indication circuit of the optimization monitoring target in the combination to the backup switching circuit is determined based on the second time period.

[0038] Further, the identification processing result includes the judgment indication circuit data that cannot normally send a signal due to a fault.

[0039] The switching processing of the judgment indication circuit is performed based on the switching control strategy to obtain an identification processing result, and whether the printing method of the printing paper needs to be improved is determined based on the identification processing result.

[0040] Specifically, whether the printing method of the printing paper needs to be improved is determined, specifically including: Based on the identification processing result, the judgment indication circuit that cannot normally send a signal due to a fault is determined as a fault circuit, and the number of the fault circuit is determined as the abnormal probability of the judgment indication circuit; With the identification processing result, the mean of the damage duration of the optimized monitoring target in different combinations is determined, the duration from the setting completion to the fault monitoring time of the fault circuit is determined based on the fault monitoring time data of the fault circuit, and is taken as the fault duration, the mean of the fault duration of different fault circuits is taken as the mean of the fault duration, and based on the mean of the fault duration, the combination with the mean of the fault duration less than the mean of the damage duration of the optimized monitoring target is determined as the poor monitoring combination. Based on the poor monitoring combination data and the abnormal probability of the judgment indication circuit, it is determined whether the printing method of the printed paper needs improvement processing.

[0041] Specifically, the abnormal probability of the judgment indication circuit is determined according to the proportion of the fault circuit in the judgment indication circuit of the optimized monitoring target.

[0042] It should be noted that when the abnormal probability is less than the preset abnormal probability threshold, at this time, since the probability of failure of the judgment indication circuit is small, even if the damage duration is long, effective monitoring can still be obtained, and therefore it is determined that the printing method of the printed paper does not need improvement processing.

[0043] Further, when the abnormal probability is not less than the preset abnormal probability threshold, if there is no poor monitoring combination, it is determined that the printing method of the printed paper does not need improvement processing.

[0044] In addition, it can be understood that if there is a poor monitoring combination, if there are multiple poor monitoring combinations at this time, it is determined that the printing method of the printed paper needs improvement processing.

[0045] In one possible specific embodiment: When the mean of the damage duration is greater than 0.5 times the total duration of the entire growth cycle of the plant, the monitoring target is determined as the optimized monitoring target, and a standby switching circuit is set for it. Once switched to the standby switching circuit, it is in the pass-through state, and it can be determined whether the judgment indication circuit is abnormal.

[0046] When there is no alarm target in the combination, the determination of the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the standby switching circuit is performed using the first time period, if the total number is greater than 20, it is determined that the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the standby switching circuit is unnecessary switching processing, if the total number is not greater than the preset alarm target number threshold, therefore, the determination of the switching control strategy of the judgment indication circuit of the optimized monitoring target in the combination to the standby switching circuit is performed using the second time period.

[0047] When the abnormal probability is less than 0.01, it is determined that the printing mode of the printed paper does not need to be improved; when the abnormal probability is not less than 0.01, if there are multiple monitoring poor combinations, it is determined that the printing mode of the printed paper needs to be improved.

[0048] In particular, the method for determining the optimized monitoring target in the monitoring targets is: The damage time of different plants of the plant type corresponding to the monitoring target in history is determined according to the damage time of the printed paper in the same greenhouse environment of the plant type corresponding to the monitoring target; Based on the damage time of different plants of the plant type corresponding to the monitoring target, the plant whose damage time does not meet the requirement is determined. The determination of whether the monitoring target is an optimized monitoring target is made by using the composition data of the plant whose damage time does not meet the requirement in the plant type corresponding to the monitoring target.

[0049] In one possible embodiment, the plant whose damage time does not meet the requirement is a plant whose damage time is greater than a preset time threshold, wherein the preset time threshold is determined according to the total time of the entire growth cycle of the plant, and the longer the total time of the entire growth cycle of the plant, the longer the preset time threshold. In one possible embodiment, the preset time threshold can be determined by multiplying a preset proportion coefficient and the total time of the entire growth cycle of the plant, and the preset proportion coefficient can be set to 0.5.

[0050] In particular, the determination of whether the monitoring target is an optimized monitoring target is made by using the composition data of the plant whose damage time does not meet the requirement in the plant type corresponding to the monitoring target, and specifically includes: If the proportion of the plant whose damage time does not meet the requirement in the plant type corresponding to the monitoring target is greater than a preset proportion threshold, for example, greater than 0.2, it is determined that the monitoring target is an optimized monitoring target.

[0051] In further, the method for determining the switching control strategy of the judgment indication circuit to the standby switching circuit is: The optimized monitoring targets of the same plant type are divided into the same combination, and the optimized monitoring target whose alarm device of the judgment indication circuit sends a signal in the combination is determined according to the signal monitoring result of the alarm device of the judgment indication circuit of the optimized monitoring target in the combination, and is taken as an alarm target. It can be understood that when the alarm target does not exist in the combination, at this time, since it is impossible to determine whether the indication circuit is working normally as soon as possible, the determination of the switching control strategy of the indication circuit of the optimization monitoring target in the combination to the standby switching circuit is carried out based on the first time period, that is, the indication circuit of the optimization monitoring target in the combination is switched to the standby switching circuit every first time period.

[0052] In the above step, by using the first time period for switching control processing, the working state of the indication circuit can be determined, so that even if the insulation state of the printed paper changes, the indication circuit still cannot effectively display the real plant growth state, and the reliability of the monitoring processing of the plant growth state is improved.

[0053] It should be noted that if the alarm target exists in the combination, at this time, the composition data of the alarm target in the combination is determined, and when the number of alarm targets in the combination meets the requirements, at this time, the number of alarm targets is relatively large, and since the growth environment is the same, it can be roughly judged that other plants in the combination are also likely to send alarm signals as soon as possible, and therefore, the switching control strategy of the indication circuit of the optimization monitoring target in the combination to the standby switching circuit is determined to be no switching processing, so as to ensure the running stability of the indication circuit.

[0054] The moment when the alarm device of the alarm target indication circuit sends a signal is taken as the alarm moment; It should be noted that in the above step, the interval duration between the alarm moment of different alarm targets and the current moment is determined based on different alarm moments of different alarm targets, and when the number of alarm targets with an interval duration greater than a preset interval duration threshold is greater than a preset target number threshold, at this time, it can still be roughly judged that other plants in the combination are also likely to send alarm signals as soon as possible, and therefore, the switching control strategy of the indication circuit of the optimization monitoring target in the combination to the standby switching circuit is determined to be no switching processing, so as to ensure the running stability of the indication circuit.

[0055] In the above step, the interval duration between the alarm moment of the alarm target and the current moment is combined to realize the evaluation of the probability that the insulation state of the printed paper of the optimization monitoring target in the combination is destroyed in the future period, so as to avoid frequent switching to the standby switching circuit in the case that the probability of being destroyed is relatively large, and the technical problem of poor working reliability of the indication circuit is avoided, so as to ensure the working stability of the indication circuit.

[0056] Determine the switching control strategy of the judgment indication circuit to the standby switching circuit in the combination based on the alarm target data in the combination and the alarm time of different alarm targets.

[0057] Specifically, determine the switching control strategy of the judgment indication circuit to the standby switching circuit in the combination based on the alarm target data in the combination and the alarm time of different alarm targets, specifically including: Determine the alarm target with an interval time longer than a preset interval time threshold based on the interval time between the alarm time of different alarm targets and the current time. Based on the interval time longer than the preset interval time threshold, for example, the alarm target of one week and the total number of all alarm targets, if the total number is greater than a preset alarm target number threshold, then determine the switching control strategy of the judgment indication circuit to the standby switching circuit in the combination as no switching processing is required, if the total number is not greater than the preset alarm target number threshold, then determine the switching control strategy of the judgment indication circuit to the standby switching circuit in the combination based on the second time period.

[0058] It can be understood that the first time period is less than the second time period, and in one possible embodiment, the first time period is 3 days and the second time period is 5 days.

[0059] Further, the embodiment 5 further determines whether the printing method of the printed paper needs to be improved, specifically including: Based on the identification processing result, determine the judgment indication circuit that cannot normally send signals due to failure as a failure circuit. It should be noted that if the number of failure circuits is within a specified range in the above steps, the probability of failure of the judgment indication circuit is relatively small at this time, and thus the printed paper can be effectively monitored even if the damage time is relatively long, and thus it is determined that the printing method of the printed paper does not need to be improved.

[0060] In the present application, the number of failure circuits is determined to avoid the technical problem that the monitoring reliability of the plant growth state is poor due to the fact that the running state of the judgment indication circuit is not good and the printing method of the printed paper is not improved, for example, the insulation resistance is reduced and the printing width of the conductive paste is increased, thereby improving the reliability of the monitoring processing of the plant growth state.

[0061] Determine the mean value of the damage time of the optimal monitoring target in different combinations based on the identification processing result. According to the fault monitoring time data of the fault circuit and the average of the damage duration of the optimization monitoring target in different combinations, it is determined whether the printing mode of the printing paper needs to be improved.

[0062] Further, according to the fault monitoring time data of the fault circuit and the average of the damage duration of the optimization monitoring target in different combinations, it is determined whether the printing mode of the printing paper needs to be improved, specifically including: Based on the fault monitoring time data of the fault circuit, the duration from the setting completion to the fault monitoring time of the fault circuit is determined and taken as the fault duration, and the average of the fault duration of different fault circuits is taken as the average of the fault duration. Based on the average of the fault duration, the combination in which the average of the fault duration is less than the average of the damage duration of the optimization monitoring target is determined and taken as the poor monitoring combination. Based on the poor monitoring combination data, it is determined whether the printing mode of the printing paper needs to be improved.

[0063] It can be understood that when there are multiple poor monitoring combinations, it is determined that the printing mode of the printing paper needs to be improved.
