Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments.
It is well known that in agricultural irrigation systems, field water management is not separated from gate valves. The gate valve has the advantages of simple structure, low cost and the like, and plays a very important role in an agricultural irrigation system. However, most gate valves are still in the stage of manually opening and closing the valves, so that not only is the actual operation very inconvenient, but also the development trend of intelligent agriculture is reversed. Further, the existing gate valve does not have a function of controlling the switching value. That is, the existing gate valve can be opened or closed only completely, and the switching amount cannot be adjusted. Therefore, in some application scenarios, under the state that the gate valve is fully opened, the excessive water flow may directly wash out seedlings, thereby bringing about economic loss.
Although there are some intelligent valves that can be opened and closed automatically and can adjust the opening and closing amount automatically, the implementation of these functions depends on a chip capable of processing complex instructions, and is therefore costly. Moreover, the above-mentioned intelligent valve is generally complex in structure and is difficult to be widely used in application scenes (such as agricultural application scenes) where the environment is complex and severe.
In order to solve the above problems, embodiments of the present application provide a gate valve control method and system, a gate valve, and a computer readable storage medium, so as to solve the problem that the existing gate valve cannot adjust the switching value.
A specific application scenario of the gate valve control method according to the present application will be described below with reference to fig. 1.
Fig. 1 is a schematic diagram of an application scenario of a gate valve control method according to an embodiment of the present application. As shown in fig. 1, the application scenario provided by the embodiment of the application is a farm irrigation application scenario. Specifically, the scenario includes a gate valve 110, a processor 120 connected to the gate valve 110, and a driver 130 connected to the processor 120. Specifically, the gate valve 110 includes a shutter 111 connected to a driver 130, a first limit detector 112 and a second limit detector 113 respectively connected to the processor 120. In some embodiments, gate valve 110 and driver 130 form a gate valve system, and processor 120 may be disposed in the gate valve system or may be independent of the end of the gate valve system.
The shutter 111 is used for controlling the opening amount of a pipeline (such as a water pipe), the first limit detector 112 is used for detecting a first limit trigger signal (such as an upper limit trigger signal, also called an opening limit trigger signal) of the shutter 111, the second limit detector 113 is used for detecting a second limit trigger signal (such as a lower limit trigger signal, also called a closing limit trigger signal) of the shutter 111, and the processor 120 is used for receiving and processing the first limit trigger signal detected by the first limit detector 112 and the second limit trigger signal detected by the second limit detector 113. In addition, the processor 120 is further configured to issue a control instruction to the driver 130 based on the received related signal, so as to control the movement amount of the shutter 110 by using the driver 130, and further control the switching value of the gate valve 110.
Illustratively, during actual use, processor 120 is configured to determine relative positional information of the pipeline with respect to a travel range of ram 111; determining travel relation information between the driver 130 and the shutter 111; the switching amount control relation information between the driver 130 and the gate valve 110 is determined based on the relative position information and the travel relation information, so that the switching amount of the gate valve 110 is controlled by the driver 130 based on the switching amount control relation information.
Further, the processor 120 is configured to determine switching value control relation information between the driver 130 and the gate valve 110; based on the switching amount control relation information, the switching amount of the gate valve 110 is controlled by the driver 130.
The gate valve control method provided by the present application will be described in detail with reference to fig. 2 to 11.
Fig. 2 is a flow chart of a gate valve control method according to an embodiment of the application. Specifically, the gate valve control method provided by the embodiment of the application is applied to a gate valve comprising a gate plate. The gate valve is used for controlling the opening amount of the pipeline, namely, the opening amount of the pipeline connected with the gate valve. The shutter corresponds to a driver for powering the movement of the shutter.
As shown in fig. 2, the gate valve control method provided by the embodiment of the application includes the following steps.
Step S100, determining relative position information of the pipe line with respect to the stroke section of the shutter.
For example, the travel range of the shutter may be understood as the movable range of the shutter. For example, the gate plate is correspondingly provided with an opening stroke limit position and a closing stroke limit position, and a movable interval between the opening stroke limit position and the closing stroke limit position is the stroke interval of the gate plate. The opening stroke limit position refers to a stroke limit position when the flashboard is opened to the maximum value, and the closing stroke limit position refers to a stroke limit position when the flashboard is closed to the minimum value.
For example, the relative position information of the pipe with respect to the stroke zone of the ram can be understood as establishing a coordinate system with reference to the stroke zone of the ram, under which the position information of the pipe is located.
In step S200, travel relation information between the driver and the shutter is determined.
The stroke relation information between the driver and the shutter means, for example, stroke relation information between the driving amount of the driver and the moving amount of the shutter. For example, if the driver is a motor, the driving amount of the motor is one circle of forward rotation, and the moving amount of the gate plate is 5 cm in the direction approaching the opening stroke limit position, then the motor is one circle of forward rotation to move the corresponding gate plate by 5 cm in the direction approaching the opening stroke limit position, which can be regarded as the stroke relation information between the driver and the gate plate.
It should be noted that, the travel relation information is determined according to the relevant parameters of the driver, the actual size of the gate, and the like, which is not uniformly limited in the embodiment of the present application.
Step S300 of determining switching amount control relation information between the driver and the gate valve based on the relative position information and the travel relation information so as to control the switching amount of the gate valve using the driver based on the switching amount control relation information.
Illustratively, the switching amount control relation information mentioned in step S300 refers to relation information between the driving amount of the driver and the switching amount of the gate valve.
The gate valve control method provided by the embodiment of the application can determine the switching value control relation information between the driver and the gate valve by utilizing the relative position information of the pipeline relative to the travel section of the gate plate and the travel relation information between the driver and the gate plate, thereby providing a precondition for controlling the switching value of the gate valve based on the switching value control relation information. Based on the embodiment of the application, the aim of controlling the switching value of the gate valve can be realized without complex judgment logic. Particularly, when the embodiment of the application is used for improving the existing gate valve, the aim of controlling the switching value of the gate valve can be achieved, and the improved gate valve has the advantages of simple structure, low cost and the like.
Fig. 3 is a schematic flow chart of determining travel relation information between a driver and a shutter according to an embodiment of the present application. The embodiment shown in fig. 3 is extended from the embodiment shown in fig. 2, and differences between the embodiment shown in fig. 3 and the embodiment shown in fig. 2 are described in the following, and are not repeated.
Specifically, in an embodiment of the present application, the driver includes a drive motor and a rotation detector. For example, the drive motor includes a brushed motor, the rotation detector includes a single hall detector, and the single hall detector is disposed at a distal end of the brushed motor. As shown in fig. 3, the step of determining travel relation information between the driver and the shutter includes the following steps.
Step S210, detecting rotation displacement information of the driving motor by using a rotation detector.
Illustratively, the rotational displacement information includes rotational direction information and rotational amount information.
Step S220, determining movement displacement information of the shutter corresponding to the rotation displacement information.
Illustratively, the movement displacement information includes movement direction information and movement amount information. The movement displacement information of the shutter corresponding to the rotational displacement information mentioned in step S220 refers to the movement displacement information of the shutter in the detection period of the rotational displacement information mentioned in step S210.
Step S230, determining travel relation information based on the rotational displacement information and the movement displacement information.
According to the gate valve control method provided by the embodiment of the application, the rotation displacement information of the driving motor is detected by the rotation detector, the movement displacement information of the gate plate corresponding to the rotation displacement information is determined, and then the travel relation information is determined based on the rotation displacement information and the movement displacement information, so that the purpose of determining the travel relation information between the driver and the gate plate is realized.
Since the driver includes the drive motor and the rotation detector, i.e., the driver belongs to the rotation drive type driver, the embodiment of the present application can save costs. Particularly, when the single Hall detector is used for detection, the cost can be further saved. Therefore, the embodiment of the application can practically consider the cost and expense problem of agricultural irrigation application scenes. In addition, it can be understood that other magnetic effect detectors such as a double hall detector can be used to replace a single hall detector in the embodiment of the application, so as to further improve the adaptability and application universality of the gate valve control method in the embodiment of the application.
Fig. 4 is a flow chart illustrating determining relative position information of a pipeline relative to a stroke zone of a ram according to an embodiment of the application. The embodiment shown in fig. 4 is extended from the embodiment shown in fig. 2, and differences between the embodiment shown in fig. 4 and the embodiment shown in fig. 2 are described in detail, so that details of the differences will not be repeated.
As shown in fig. 4, in the embodiment of the present application, the step of determining the relative position information of the pipe with respect to the stroke section of the shutter includes the following steps.
Step S110, determining first stroke limit position information corresponding to the shutter.
Illustratively, the first travel limit position information refers to position information corresponding to the first travel limit position. The first stroke limiting position may be the above-mentioned opening stroke limiting position or the above-mentioned closing stroke limiting position, which is not uniformly limited in the embodiment of the present application.
Step S120, determining first flux limiting position information corresponding to the pipeline.
The first flux limiting position information is, for example, position information corresponding to the first flux limiting position. The first flux limiting position can be an opening flux limiting position or a closing flux limiting position. The opening flux limit position refers to an edge limit position when the pipeline is opened to a maximum value. The closed flux limit position refers to an edge limit position when the pipeline is completely closed.
Step S130, determining the relative position information based on the first travel limit position information and the first flux limit position information.
According to the gate valve control method, the first flux limiting position information corresponding to the pipeline is determined by determining the first stroke limiting position information corresponding to the gate plate, and then the relative position information is determined based on the first stroke limiting position information and the first flux limiting position information, so that the purpose of determining the relative position information of the pipeline relative to the stroke interval of the gate plate is achieved. Compared with a mode of determining relative position information by means of a world coordinate system, the method and the device can simplify calculation steps.
Specific implementations of determining relative position information based on the first travel limit position information and the first flux limit position information are illustrated below in connection with fig. 5-7.
Fig. 5 is a schematic flow chart of determining relative position information based on first travel limit position information and first flux limit position information according to an embodiment of the application. The embodiment shown in fig. 5 is extended from the embodiment shown in fig. 4, and differences between the embodiment shown in fig. 5 and the embodiment shown in fig. 4 are described in detail, so that the description is omitted.
As shown in fig. 5, in the embodiment of the present application, the step of determining the relative position information based on the first travel limit position information and the first flux limit position information includes the following steps.
Step S131, determining first distance information based on the first travel limit position information and the first flux limit position information. Wherein the first distance information characterizes a distance between the first travel limit position and the first flux limit position.
Step S132, determining second flux limiting position information corresponding to the pipeline.
Step S133, determining relative position information based on the first distance information and the second flux limiting position information.
The first flux limiting position information is illustratively on flux limiting position information, and the second flux limiting position information is off flux limiting position information. For another example, the first flux limiting position information is closed flux limiting position information, and the second flux limiting position information is open flux limiting position information.
To further clarify the manner in which the relative position information is determined, the following is exemplified in connection with fig. 6. Fig. 6 is a schematic diagram showing a relative positional relationship between a pipeline and a shutter according to an embodiment of the present application. As shown in fig. 6, the shutter 610 and the pipe 620 have a correspondence relationship. The shutter 610 corresponds to a first stroke limit position L1 and a second stroke limit position L2. In connection with the orientation shown in fig. 6, the first travel limit position L1 may be considered as a closing travel limit position (also referred to as a lower travel limit position), and the second travel limit position L2 may be considered as an opening travel limit position (also referred to as an upper travel limit position). The conduit 620 corresponds to a first flux limit position S1 and a second flux limit position S2. In connection with the orientation shown in fig. 6, the first flux limiting position S1 may be considered an open flux limiting position (also known as an upper edge limiting position), and the second flux limiting position S2 may be considered a closed flux limiting position (also known as a lower edge limiting position).
It can be seen that the first distance information mentioned in the above step S131 is D2. Since the second throughput limit position information (S2 information) corresponding to the pipeline is determined, D1 can also be known. On the basis of which the above mentioned relative position information can be determined.
Fig. 7 is a flowchart illustrating a process for determining relative position information based on first travel limit position information and first flux limit position information according to another embodiment of the application. The embodiment shown in fig. 7 is extended from the embodiment shown in fig. 4, and differences between the embodiment shown in fig. 7 and the embodiment shown in fig. 4 are described in detail, so that the description is omitted.
As shown in fig. 7, in the embodiment of the present application, the step of determining the relative position information based on the first travel limit position information and the first flux limit position information includes the following steps.
Step S134, determining first distance information based on the first travel limit position information and the first flux limit position information. Wherein the first distance information characterizes a distance between the first travel limit position and the first flux limit position.
Step S135, determining pipeline diameter information corresponding to the pipeline.
Illustratively, the conduit diameter information may be conduit inner diameter information or conduit nominal diameter information. If the line thickness is not considered, as exemplified in fig. 6, the line diameter information can be understood as the distance information between S1 and S2.
In some embodiments, the step of determining the conduit diameter information corresponding to the conduit may be performed as obtaining conduit diameter information corresponding to the conduit.
Step S136, determining relative position information based on the first distance information and the line diameter information.
As can be seen from a comparison between the embodiment shown in FIG. 5, the embodiment of the present application can determine the final relative position information directly based on the pipeline diameter information corresponding to the pipeline without determining the second throughput limit position information corresponding to the pipeline. Because the size of the piping is predetermined and is not easily changed in a field irrigation scenario, the embodiment of the present application can more quickly determine the relative position information based on less calculation cost than the embodiment shown in fig. 5.
It will be appreciated that the gate valve control method described in the embodiments of fig. 2 to 7 may also be implemented by hardware such as a server. Specifically, the same server is connected with a plurality of gate valves, and then the purpose of commonly controlling the connected gate valves can be achieved based on the same server.
Fig. 8 is a flow chart of a gate valve control method according to another embodiment of the application. Specifically, the gate valve control method provided by the embodiment of the application is applied to a gate valve comprising a gate plate. The gate valve is used for controlling the opening amount of the pipeline, namely, the opening amount of the pipeline connected with the gate valve. The shutter corresponds to a driver for powering the movement of the shutter.
As shown in fig. 8, the gate valve control method provided by the embodiment of the application includes the following steps.
Step S400, determining switching value control relation information between the driver and the gate valve.
Illustratively, the switching amount control relation information mentioned in step S400 is obtained based on the gate valve control method mentioned in any of the above embodiments.
In some embodiments, the step of determining switching amount control relation information between the driver and the gate valve may be performed as acquiring switching amount control relation information between the driver and the gate valve. Therefore, the execution subject of the gate valve control method according to the embodiment of the present application may be a farmer or a server or an electronic device affiliated to the farmer.
Step S500, based on the switching value control relation information, the switching value of the gate valve is controlled by the driver.
The gate valve control method provided by the embodiment of the application can enable the gate valve to have the function of automatically adjusting the switching value on the basis of not changing the hardware structure of the gate valve as much as possible. Based on the above, the embodiment of the application not only ensures that the gate valve meets the requirement of automatic switching value adjustment (especially irrigation requirement), but also ensures that the improved gate valve has the advantages of simple structure, low cost and the like.
Although the above embodiments achieve the purpose of controlling the switching value of the gate valve, in the agricultural irrigation system, the control accuracy can directly affect the irrigation effect, so how to further reduce the control error and improve the control accuracy becomes a technical problem to be solved.
Fig. 9 is a flow chart of a gate valve control method according to another embodiment of the application. The embodiment shown in fig. 9 is extended from the embodiment shown in fig. 2, and differences between the embodiment shown in fig. 9 and the embodiment shown in fig. 2 are described in detail, so that details of the differences will not be repeated. It will be appreciated that the embodiment of fig. 9 may also be extended from any of the embodiments of fig. 3-8 described above.
Specifically, in the embodiment of the present application, the stroke interval of the shutter corresponds to a first stroke limit position, and the first stroke limit position corresponds to a first limit detector. As shown in fig. 9, the gate valve control method provided by the embodiment of the application further includes the following steps.
In step S610, if it is determined that the shutter should reach the first stroke limit position based on the real-time driving amount of the driver, the shutter is detected by the first limit detector.
In step S620, if the first limit detector does not detect the shutter, the shutter is moved to the first stroke limit position.
The first stroke limit position is an opening stroke limit position, and correspondingly, the first limit trigger signal is an opening limit trigger signal, that is, a limit trigger signal sent when the first limit detector detects the flashboard.
For example, in the actual application of the gate valve, if it is determined that the shutter should reach the first stroke limit position based on the real-time driving amount of the driver, it is detected whether the shutter really reaches the first stroke limit position by the first limit detector. If the shutter plate reaches the first stroke limit position, it is explained that the above-mentioned switching amount control relation information is accurate and no additional error is introduced. If the shutter does not reach the first stroke limit position, it is indicated that there is an error in the above-mentioned switching amount control relation information, the shutter may be moved to the first stroke limit position, and the switching amount control relation information may be corrected based on the movement amount calibration.
The embodiment of the application can calibrate the information of the control relation of the switching value, thereby fully ensuring the control accuracy. Especially for the brush motor and the single Hall detector with low cost, the embodiment of the application can reduce or even eliminate errors (such as inertial errors) caused by the single Hall detector, thereby ensuring control accuracy.
Fig. 10 is a flow chart of a gate valve control method according to still another embodiment of the application. The embodiment shown in fig. 10 is extended from the embodiment shown in fig. 9, and differences between the embodiment shown in fig. 10 and the embodiment shown in fig. 9 are described in detail, so that details of the differences will not be repeated.
Specifically, in the embodiment of the application, the stroke interval of the flashboard is also correspondingly provided with a second stroke limit position, and the second stroke limit position is correspondingly provided with a second limit detector. As shown in fig. 10, the gate valve control method provided by the embodiment of the application further includes the following steps.
In step S630, if it is determined that the shutter should reach the second stroke limit position based on the real-time driving amount of the driver, the shutter is detected by the second limit detector.
In step S640, if the second limit detector does not detect the shutter, the shutter is moved to the second stroke limit position.
The second stroke limit position is a closing stroke limit position, and correspondingly, the second limit trigger signal is a closing limit trigger signal, that is, a limit trigger signal sent when the second limit detector detects the flashboard.
It should be noted that, the design principle of the embodiment of the present application is the same as that of the embodiment shown in fig. 9, so that the embodiment of the present application will not be described in detail.
