[0003] The patent with publication number CN114365649A discloses a smart greenhouse environment monitoring and control system, including an Internet of Things host, a cloud server, a mobile terminal, a monitoring system and an output execution system. The Internet of Things host and the cloud service are connected through a wireless LAN module, and the cloud server and the mobile terminal establish a network connection through a WIFI module. The Internet of Things host is connected to the monitoring system and the output execution system, and a PLC controller is provided between the output execution system and the Internet of Things host. The present invention realizes scientific monitoring and planting, promotes the development of intelligent agricultural greenhouses, meets the needs of modern management of agricultural greenhouses, effectively reduces agricultural production costs, and promotes agriculture towards high quality and high returns.

[0004] However, when raising seedlings in the greenhouse, the greenhouse planting area cannot be reasonably planned, and different types of seedlings cannot be mixed or planted individually, which reduces the utilization rate of the greenhouse planting area. At the same time, the impact of environmental control cannot be analyzed in real time, so that the efficiency of greenhouse environmental regulation cannot be accurately inferred, resulting in unnecessary control costs.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems and to propose a greenhouse seedling environment monitoring and control system based on data analysis.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A greenhouse seedling environment monitoring and control system based on data analysis, comprising a greenhouse monitoring and control center, wherein the greenhouse monitoring and control center is communicatively connected to a seedling overall planning unit, an environmental control analysis unit, and a regulation efficiency evaluation unit;

[0009] The overall planning unit for seedling cultivation marks each type of seedling cultivation as a planting subject, divides the greenhouse area into several planting areas, analyzes and matches the planting subjects to be planted in real time with the planting areas, obtains the required environmental factors of the planting subjects and the supply environmental factors of the planting areas, and matches them. If the match is qualified, it is set as a matching planting combination; otherwise, it is set as a non-matching planting combination; and mixed planting analysis is performed on the matching planting combination. After the analysis is completed, the seedling cultivation planting area planning is carried out;

[0010] After completing the overall planning of seedling cultivation, the environmental control analysis unit conducts environmental control analysis on the planting area, obtains environmental control frequency impact data and environmental control error impact data, and infers whether the current environmental control analysis is normal based on data comparison. If it is normal, monitoring will continue; if it is abnormal, control and rectification will be carried out. At the same time, the regulation and control efficiency evaluation unit conducts efficiency evaluation on the greenhouse area environmental control, collects regulation trend impact information and regulation span impact information, and determines whether there is an impact on the environmental regulation efficiency based on information analysis. If there is an impact, control and rectification will be carried out while controlling the environmental impact. Otherwise, only the environmental control will be rectified.

[0011] As a preferred embodiment of the present invention, the mixed planting analysis process is as follows:

[0012] The matching planting time factor and the matching planting parameter factor are obtained. If the matching planting time factor exceeds the non-overlapping duration threshold of the time period, or the matching planting parameter factor exceeds the parameter maximum floating span deviation value threshold, the corresponding type of planting subject is marked as a staggered combination; if the matching planting time factor does not exceed the non-overlapping duration threshold of the time period, and the matching planting parameter factor does not exceed the parameter maximum floating span deviation value threshold, the corresponding type of planting subjects in the current planting area are mixedly planted.

[0013] As a preferred embodiment of the present invention, the matching planting time factor and the matching planting parameter factor are respectively the non-overlapping duration of the environmental parameters of the required environmental factors of different planting subjects in a planting area corresponding to the stable supply period of the planting area, and the numerical deviation value of the average interval period deviation value of the corresponding growth links of different planting subjects in the same planting area and the maximum floating span of the environmental parameters of the required environmental factors when the growth environment alternates.

[0014] As a preferred embodiment of the present invention, the environmental control frequency influence data and the environmental control error influence data include the continuous frequency of deviation between the required environmental factors of any planting subject and the same type of parameters of the supplied environmental factors during the supply environmental factor parameter control stage in the planting area of ​​mixed planting, and the floating frequency of the error between the real-time control parameter values ​​and the same type of parameters of the required environmental factors during the supply environmental factor parameter control stage in the planting area of ​​single seedling cultivation.

[0015] As a preferred embodiment of the present invention, if the environmental control frequency impact data does not exceed the continuous frequency threshold, and the environmental control error impact data does not exceed the error floating frequency threshold, it is inferred that the environmental control analysis of the current greenhouse area is normal; if the environmental control frequency impact data exceeds the continuous frequency threshold, or the environmental control error impact data exceeds the error floating frequency threshold, it is inferred that the environmental control analysis of the current greenhouse area is abnormal.

[0016] As a preferred embodiment of the present invention, the control trend impact information and the control span impact information are respectively the numerical ratio of the same trend duration and the non-same trend duration of the supply environment factor parameter control trend and the real-time environment same type parameter floating trend during the greenhouse area environment control stage, and the reciprocating floating span value of the shortening speed of the parameter deviation value corresponding to the required environment factor parameters and the supply environment factor parameters when the environment parameters float during the greenhouse area environment control stage.

[0017] As a preferred embodiment of the present invention, if the control trend impact information exceeds the duration value ratio threshold, or the control span impact information exceeds the speed reciprocating floating span threshold, it is inferred that there is an impact on the control efficiency of the current environment control stage; if the control trend impact information does not exceed the duration value ratio threshold, and the control span impact information does not exceed the speed reciprocating floating span threshold, it is inferred that there is no impact on the control efficiency of the current environment control stage.

[0018] As a preferred embodiment of the present invention, the greenhouse monitoring and control center is communicatively connected to a greenhouse seedling raising efficiency monitoring unit, the greenhouse seedling raising efficiency monitoring unit collects seedling raising efficiency monitoring information, and substitutes it into the formula to obtain the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage. If the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage exceeds the seedling raising efficiency monitoring coefficient threshold, it is inferred that the seedling raising efficiency monitoring in the greenhouse seedling raising stage is abnormal; if the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage does not exceed the seedling raising efficiency monitoring coefficient threshold, it is inferred that the seedling raising efficiency monitoring in the greenhouse seedling raising stage is normal.

[0019] As a preferred embodiment of the present invention, the seedling efficiency monitoring information includes the gradually increasing growth rate deviation value of the same type of seedlings planted at the same time in the greenhouse seedling stage corresponding to the growth cycle, the deviation value of the environmental factor parameters supplied at different locations in any planting area when the environmental control of the planting area is qualified in the greenhouse seedling stage, and the numerical deviation value of the seedling progress deviation duration corresponding to the period before and after the greenhouse environment control in the greenhouse seedling stage.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the greenhouse is planned for seedling types, and the planting area is reasonably planned according to different seedling types, so as to improve the efficiency of greenhouse environmental control and avoid abnormal planting of different types of seedlings caused by environmental control. At the same time, after reasonable planning of different seedling types, the utilization rate of the planting area can be greatly improved, and the unreasonable planning of planting areas for different numbers of seedlings can be avoided, which reduces the greenhouse planting efficiency;

[0022] Conduct environmental control analysis on the planting area to infer whether the real-time environmental control meets the needs of the planting subject after the planting subject planning is completed in the planting area, thereby ensuring that the planting environment of the planting area can fit the demand environment of the planting subject, improving the planting efficiency of the planting subject, and also improving the planting adaptability of the planting area.

[0023] 2. In the present invention, the efficiency of greenhouse area environmental control is evaluated. Through the efficiency evaluation, it is inferred whether the real-time environmental impact during the current greenhouse area environmental control causes the control efficiency to decrease, so as to facilitate targeted environmental control when the control is abnormal, and to provide continuous environmental warning when the control is normal, thereby improving the environmental control efficiency of the greenhouse area and ensuring the supply satisfaction of the environmental factors in the greenhouse area;

[0024] The seedling raising efficiency is monitored during the greenhouse seedling raising stage. Through real-time seedling raising efficiency monitoring, it is inferred whether the real-time greenhouse environmental control meets the seedling raising needs, thereby indirectly monitoring the greenhouse environmental control, improving the greenhouse monitoring and control efficiency and ensuring the probability that the greenhouse regulation environment meets the seedling raising environment.

[0025] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0027] Figure 2 This is a principle block diagram of the second embodiment of the present invention. DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] See also Figure 1 As shown, a greenhouse seedling environment monitoring and control system based on data analysis includes a greenhouse monitoring and control center, wherein the greenhouse monitoring and control center is communicatively connected to a seedling overall planning unit, an environmental control analysis unit, and a regulation efficiency evaluation unit;

[0031] The greenhouse monitoring and control center generates a seedling overall planning signal and sends the seedling overall planning signal to the seedling overall planning unit. After receiving the seedling overall planning signal, the seedling overall planning unit plans the greenhouse seedling type and reasonably plans the planting area according to different seedling types, so as to improve the efficiency of greenhouse environmental control and avoid abnormal planting of different types of seedlings caused by environmental control. At the same time, reasonable planning of different seedling types can greatly improve the utilization rate of the planting area and avoid unreasonable planning of planting areas for different numbers of seedlings, which reduces the greenhouse planting efficiency.

[0032] Each type of seedling is marked as a planting subject, and the greenhouse area is divided into several planting areas. The planting subjects to be planted in real time are analyzed and matched with the planting areas to obtain the required environmental factors of the planting subjects, specifically temperature, moisture, oxygen content, etc.; the supply environmental factors of the planting area are collected, specifically soil moisture, soil temperature, and soil porosity;

[0033] The required environmental factors of the planting subject are matched with the supplied environmental factors of the planting area. If the value of the required environmental factor is within the value range of the supplied environmental factor, the corresponding planting subject and the planting area are set as a matching planting combination; otherwise, if the value of the required environmental factor is not within the value range of the supplied environmental factor, the corresponding planting subject and the planting area are set as a non-matching planting combination;

[0034] Perform mixed planting analysis on different types of planting subjects corresponding to the matching planting combination, and obtain the non-overlapping duration of the stable supply period of the planting area corresponding to the environmental parameters of the required environmental factors of different planting subjects in the same planting area, where the stable supply period means that the supply environmental factors of the planting area can continuously meet the required environmental factors until the end of the current supply cycle; at the same time, obtain the numerical deviation value of the average interval period deviation value of the growth link corresponding to different planting subjects in the same planting area and the maximum floating span of the environmental parameters of the required environmental factors when the growth environment alternates, and mark the non-overlapping duration of the stable supply period of the planting area corresponding to the environmental parameters of the required environmental factors of different planting subjects in the same planting area, and the numerical deviation value of the average interval period deviation value of the growth link corresponding to different planting subjects in the same planting area and the maximum floating span of the environmental parameters of the required environmental factors when the growth environment alternates as matching planting time factors and matching planting parameter factors, and compare them with the non-overlapping duration threshold of the time period and the maximum floating span deviation threshold of the parameter respectively:

[0035] If the non-overlapping duration of the environmental parameters of the required environmental factors of different planting subjects in the same planting area corresponding to the stable supply period of the planting area exceeds the non-overlapping duration threshold of the period, or the numerical deviation value of the average interval period deviation value of the corresponding growth links of different planting subjects in the same planting area and the maximum floating span of the environmental parameters of the required environmental factors when the growth environment alternates exceeds the parameter maximum floating span deviation value threshold, it is inferred that the corresponding type of planting subjects in the current matching planting combination are not suitable for mixed planting, and the corresponding type of planting subjects in the staggered combination are marked as staggered combinations, and the planting areas of the corresponding types of planting subjects in the staggered combinations are re-matched;

[0036] If the non-overlapping duration of the environmental parameters of the required environmental factors of different planting subjects in the same planting area corresponding to the stable supply period of the planting area does not exceed the non-overlapping duration threshold of the period, and the numerical deviation value of the average interval period deviation value of the corresponding growth links of different planting subjects in the same planting area and the maximum floating span of the environmental parameters of the required environmental factors when the growth environment alternates does not exceed the parameter maximum floating span deviation value threshold, it is inferred that the corresponding type of planting subjects in the current matching planting combination are suitable for mixed planting, and the corresponding type of planting subjects in the current planting area are sent to the greenhouse monitoring and control center. After receiving the planting subjects, the greenhouse monitoring and control center plans the planting area with the current matching planting combination, and carries out seedling cultivation in the planned area;

[0037] If the non-matching planting combination and the staggered combination cannot match the appropriate planting area, separate seedlings will be raised on the premise that the planting area meets the requirements of the main planting body;

[0038] After the overall planning of seedling cultivation is completed, an environmental control analysis signal is generated and sent to the environmental control analysis unit. After receiving the environmental control analysis signal, the environmental control analysis unit performs environmental control analysis on the planting area to infer whether the real-time environmental control of the planting area meets the needs of the planting subject after the planting subject planning is completed, thereby ensuring that the planting environment of the planting area can fit the required environment of the planting subject, improving the planting efficiency of the planting subject, and also improving the planting adaptability of the planting area;

[0039] The continuous frequency of deviation between the required environmental factors of any planting subject and the same type of parameters of the supplied environmental factors in the supply environmental factor parameter control stage in the planting area of ​​mixed planting is obtained. It can be understood that the supply environmental factor parameters cannot be guaranteed to be consistent with the optimal parameters of the required environmental factors in mixed planting, but the numerical range requirements of the required environmental factors can be guaranteed. Therefore, if the same type of planting subject has never been at the optimal parameters during the planting stage, there will be no occasional impact and continuous occurrence will not cause planting abnormalities, but there is a risk of low growth efficiency; therefore, environmental control in the mixed planting process needs to be combined with multiple types of planting subjects for overall regulation;

[0040] The floating frequency of the error between the real-time control parameter value of the supply environmental factor parameter in the control stage of the supply environmental factor parameter in the planting area for single seedling cultivation and the numerical error of the same type of parameter of the required environmental factor is obtained, and the continuous frequency of the deviation between the required environmental factor and the same type of parameter of the supply environmental factor of any planting subject in the supply environmental factor parameter control stage in the planting area for mixed planting, and the floating frequency of the error between the real-time control parameter value of the supply environmental factor parameter in the control stage of the supply environmental factor parameter in the planting area for single seedling cultivation and the numerical error of the same type of parameter of the required environmental factor are marked as environmental control frequency influence data and environmental control error influence data, respectively, and compared with the continuous frequency threshold and the error floating frequency threshold, respectively:

[0041] If the continuous frequency of the deviation between the required environmental factor and the same type of parameter of the supplied environmental factor of any planting subject in the supply environmental factor parameter control stage in the mixed planting area does not exceed the continuous frequency threshold, and the floating frequency of the error between the real-time control parameter value and the same type of parameter value of the required environmental factor in the supply environmental factor parameter regulation stage in the planting area for single seedling cultivation does not exceed the error floating frequency threshold, it is inferred that the environmental control analysis of the current greenhouse area is normal, and a normal greenhouse environmental control signal is generated and sent to the greenhouse monitoring and control center;

[0042] If the continuous frequency of the deviation between the required environmental factor and the same type of parameter of the supplied environmental factor of any planting subject in the supply environmental factor parameter control stage in the planting area of ​​mixed planting exceeds the continuous frequency threshold, or the floating frequency of the error between the real-time control parameter value and the same type of parameter value of the required environmental factor in the supply environmental factor parameter regulation stage in the planting area of ​​single seedling cultivation exceeds the error floating frequency threshold, it is inferred that the environmental control analysis of the current greenhouse area is abnormal, and a greenhouse environmental control abnormality signal is generated and sent to the greenhouse monitoring and control center. At the same time, a control efficiency evaluation signal is generated and sent to the control efficiency evaluation unit. After receiving the control efficiency evaluation signal, the control efficiency evaluation unit evaluates the efficiency of the greenhouse area environmental control. Through the efficiency evaluation, it is inferred whether the real-time environmental impact during the environmental control of the current greenhouse area causes a decrease in the control efficiency, which is convenient for targeted environmental control when the control is abnormal, and can also perform continuous environmental early warning when the control is normal, thereby improving the environmental control efficiency of the greenhouse area and ensuring the supply satisfaction of the supply environmental factors in the greenhouse area.

[0043] The numerical ratio of the same trend duration to the non-same trend duration of the supply environmental factor parameter regulation trend and the real-time environment same type parameter floating trend in the greenhouse area environmental regulation stage is obtained, and at the same time, the reciprocating floating span value of the shortening speed of the parameter deviation value corresponding to the environmental factor parameter and the supply environmental factor parameter is obtained when the environmental parameter floats in the greenhouse area environmental regulation stage, and the numerical ratio of the same trend duration to the non-same trend duration of the supply environmental factor parameter regulation trend and the real-time environment same type parameter floating trend in the greenhouse area environmental regulation stage, and the reciprocating floating span value of the shortening speed of the parameter deviation value corresponding to the environmental factor parameter and the supply environmental factor parameter when the environmental parameter floats in the greenhouse area environmental regulation stage are marked as the regulation trend impact information and the regulation span impact information, and are compared with the duration ratio threshold and the speed reciprocating floating span threshold respectively:

[0044] If the value ratio of the same trend duration and non-same trend duration of the supply environment factor parameter control trend and the real-time environment same type parameter floating trend in the greenhouse area environment control stage exceeds the value ratio threshold, or the reciprocating floating span value of the speed required to shorten the environmental factor parameter and the supply environment factor parameter corresponding parameter deviation value when the environmental parameter floats in the greenhouse area environment control stage exceeds the speed reciprocating floating span threshold, it is inferred that there is an impact on the control efficiency of the current environment control stage, and a high efficiency impact signal is generated and sent to the greenhouse monitoring and control center; if the current greenhouse monitoring and control center receives a normal greenhouse environmental control signal, it will continuously monitor the environment during the control stage of the greenhouse area; if the current greenhouse monitoring and control center receives an abnormal greenhouse environmental control signal, it will control the environmental impact while rectifying the greenhouse area environment;

[0045] If the value ratio of the same trend duration and the non-same trend duration of the supply environment factor parameter control trend and the real-time environment same type parameter floating trend in the greenhouse area environment control stage does not exceed the value ratio threshold, and the reciprocating floating span value of the required environmental factor parameter and the supply environment factor parameter corresponding parameter deviation value shortening speed when the environmental parameter floats in the greenhouse area environment control stage does not exceed the speed reciprocating floating span threshold, it is inferred that there is no impact on the control efficiency of the current environmental control stage, and a low efficiency impact signal is generated and sent to the greenhouse monitoring and control center; the greenhouse monitoring and control center performs environmental control rectification according to the corresponding type of greenhouse environmental control signal;

[0046] Embodiment 2

[0047] In the previous embodiment, the greenhouse is controlled to raise seedlings in order to ensure the efficiency of raising seedlings. Based on the previous embodiment, this embodiment adds a step of monitoring the efficiency of raising seedlings. Figure 2 As shown, the greenhouse monitoring and control center is connected to the greenhouse seedling efficiency monitoring unit in communication;

[0048] The greenhouse monitoring and control center generates a greenhouse seedling raising efficiency monitoring signal and sends the greenhouse seedling raising efficiency monitoring signal to the greenhouse seedling raising efficiency monitoring unit. After receiving the greenhouse seedling raising efficiency monitoring signal, the greenhouse seedling raising efficiency monitoring unit monitors the seedling raising efficiency in the greenhouse seedling raising stage. Through real-time seedling raising efficiency monitoring, it is inferred whether the real-time greenhouse environmental control meets the seedling raising requirements, thereby monitoring the greenhouse environmental control indirectly, improving the greenhouse monitoring and control efficiency and ensuring the probability that the greenhouse regulation environment meets the seedling raising environment.

[0049] The growth rate deviation value of the same type of seedlings planted at the same time in the greenhouse seedling stage corresponding to the growth cycle is obtained and gradually accelerated. At the same time, the deviation value of the environmental factor parameters supplied at different positions in any planting area when the environmental regulation of the planting area is qualified in the greenhouse seedling stage is obtained, and the growth rate deviation value of the same type of seedlings planted at the same time in the greenhouse seedling stage corresponding to the growth cycle is gradually accelerated, and the deviation value of the environmental factor parameters supplied at different positions in any planting area when the environmental regulation of the planting area is qualified in the greenhouse seedling stage are marked as KDV and CPC respectively;

[0050] At the same time, the numerical deviation value of the seedling progress deviation duration corresponding to the period before and after the greenhouse environment regulation in the greenhouse seedling stage is obtained, wherein the progress deviation duration is represented by the time deviation between the seedling growth progress moment in the current period and the preset moment; and the numerical deviation value of the seedling progress deviation duration corresponding to the period before and after the greenhouse environment regulation in the greenhouse seedling stage is marked as SZP;

[0051] The above collected information is uniformly marked as seedling raising efficiency monitoring information, and substituted into the formula to obtain the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage, where the formula is:

[0052] Among them, G is the seedling efficiency monitoring coefficient, mhb1, mhb2, and mhb3 are preset proportional coefficients, and e is a natural constant. β is an error correction factor with a value of 0.978;

[0053] Compare the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage with the seedling raising efficiency monitoring coefficient threshold:

[0054] If the seedling efficiency monitoring coefficient in the greenhouse seedling raising stage exceeds the seedling efficiency monitoring coefficient threshold, it is inferred that the seedling efficiency monitoring in the greenhouse seedling raising stage is abnormal, and a seedling efficiency low signal is generated and sent to the greenhouse monitoring and control center. After receiving the seedling efficiency low signal, the greenhouse monitoring and control center compares the required environmental factors of the seedling type with the supplied environmental factors to check whether they are compatible, and monitors the environmental parameter satisfaction of the required environmental factors in real time during the planting stage, and adjusts the environmental parameters when the time when the satisfaction exceeds the set time number;

[0055] If the seedling raising efficiency monitoring coefficient in the greenhouse seedling raising stage does not exceed the seedling raising efficiency monitoring coefficient threshold, it is inferred that the seedling raising efficiency monitoring in the greenhouse seedling raising stage is normal, and a seedling raising efficiency normal signal is generated and sent to the greenhouse monitoring and control center;

[0056] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0057] When the present invention is in use, the overall planning unit for seedling cultivation marks each type of seedling cultivation as a planting subject, divides the greenhouse area into a number of planting areas, analyzes and matches the planting subject to be planted in real time with the planting area, obtains the required environmental factors of the planting subject and the supply environmental factors of the planting area, and matches them. If the match is qualified, it is set as a matching planting combination; otherwise, it is set as a non-matching planting combination; and mixed planting analysis is performed on the matching planting combination, and seedling cultivation planting area planning is performed after the analysis is completed;

[0058] After completing the overall planning of seedling cultivation, the environmental control analysis unit conducts environmental control analysis on the planting area, obtains environmental control frequency impact data and environmental control error impact data, and infers whether the current environmental control analysis is normal based on data comparison. If it is normal, monitoring will continue; if it is abnormal, control and rectification will be carried out. At the same time, the regulation and control efficiency evaluation unit conducts efficiency evaluation on the greenhouse area environmental control, collects regulation trend impact information and regulation span impact information, and determines whether there is an impact on the environmental regulation efficiency based on information analysis. If there is an impact, control and rectification will be carried out while controlling the environmental impact. Otherwise, only the environmental control will be rectified.

[0059] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
