[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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.

Therefore, the phrases "in one embodiment," "in an embodiment," "an example," or "an example" appearing in various places throughout the specification do not necessarily all refer to the same embodiment or example. Furthermore, particular features, structures, or characteristics may be combined in one or more embodiments or examples in any appropriate combinations and / or subcombinations.

[0029] It should be noted that, unless otherwise specified, the technical terms in this embodiment have the common meanings understood in the relevant technical field.

[0030] Please refer to Figure 1 , an embodiment of the present invention provides a valve capable of setting automatic switches in multiple ways, the valve comprising:

[0031] An input module, used to obtain input setting data; wherein the setting data includes time data, and the number is multiple groups;

[0032] Processing modules for:

[0033] Receive the setting data and perform judgment processing in combination with the clock data read in real time to determine whether the corresponding time has been reached; wherein the clock data comes from the RTC module pre-configured by the processing module;

[0034] If so, a corresponding control signal is generated;

[0035] The execution module is used to be controlled by the control signal and perform actions to realize automatic opening and closing of the valve.

[0036] During implementation, the valve itself has a mature existing structure that should be well known to those skilled in the art, and will not be described in detail here;

[0037] RTC module, namely Real-Time Clock, is usually called clock chip. It is mainly used to provide accurate real-time time or provide accurate time reference for electronic systems. RTC module usually uses high-precision crystal oscillator as clock source to ensure the accuracy of time.

[0038] The input module adopts a touch screen with interactive function or is composed of multiple keys;

[0039] When setting, for valves with controllable opening and closing degrees, the corresponding valve opening degrees can also be set;

[0040] Furthermore, when setting data, it also includes setting of working mode; wherein the working mode includes cycle mode, single mode, etc.;

[0041] The time data includes a date and a corresponding time, and each time data is associated with a corresponding working mode; when judging whether the corresponding time is reached, the judgment can be based on the year, month, day, hour, minute and second;

[0042] It should be noted that the time data can also be set only with the corresponding moment data. In this way, the combination of the date and the corresponding time can flexibly form multiple settings with different needs; for example, one path is set to two hours, and the working mode is associated with the cycle mode; the other path is set to two and a half hours, and the working mode is associated with the cycle mode.

[0043] Furthermore, in order to improve the accuracy of control, refer to Figure 2 The embodiment of the present invention also provides another valve capable of automatically switching on and off in multiple ways. This solution is based on the above technical solution, but the difference is that the valve capable of automatically switching on and off in multiple ways also includes a timing module, which is used to provide a high-precision time signal and thereby synchronize and correct the clock data.

[0044] When applied, the timing module adopts Beidou timing module, such as N303-5Q / N305-5Q, SKG17MT, etc.

[0045] Applied in a multi-valve associated system, the Beidou timing module is introduced to provide a high-precision time standard to ensure the time consistency between each valve.

[0046] In this embodiment, the judgment and processing based on the clock data read in real time specifically includes:

[0047] Traverse the set multiple time data and compare and judge with the clock data in turn; if any time data matches the clock data, it is judged that the corresponding time has been reached, and a corresponding control signal is generated.

[0048] The above scheme obtains input setting data, and uses the setting data including time data in multiple groups to achieve multi-way setting; then the setting data is combined with the clock data read in real time for judgment and processing to determine whether the corresponding time has been reached; if so, a corresponding control signal is generated to enable the execution module to act to achieve automatic opening and closing of the valve; thereby getting rid of the fact that the control of existing valves mostly relies on the control signal of external equipment or manual operation, and achieving support for automatic opening and closing of the valve based on its own settings.

[0049] Furthermore, in order to enhance the flexibility of valve control, the valve capable of multi-channel automatic switching settings further includes a communication module, which is used to communicate and interact with an external intelligent terminal to achieve data transmission.

[0050] In this embodiment, the communication module is a wireless communication module, which uses any one of a 4G module, a 5G module, a Bluetooth module, a WiFi module, a Lora module, a Beidou module and a GPRS module;

[0051] The intelligent terminals include smart phones, personal computers, and handheld computers.

[0052] Furthermore, in another embodiment, the valve capable of multi-way automatic switching settings further includes a positioner, which transmits the feedback valve opening to the processing module.

[0053] Specifically, the positioner uses an encoder, and the processing module controls the valve based on the current error obtained, outputs a pulse width modulation signal and drives, thereby controlling the action of the execution module;

[0054] The execution module may adopt an electric execution mechanism, which mainly includes a motor output shaft, a gear reduction mechanism, a worm gear transmission mechanism and an execution mechanism output shaft.

[0055] In this embodiment, the control signal adopts a pulse modulation signal with adjustable high and low levels. By making the high and low levels adjustable, there is no need to add reverse PWM control. Compared with traditional reverse PWM control, the control steps are simplified and the control parameters are reduced.

[0056] Since the optimal frequency, duty cycle, and low-level values ​​in the control process are difficult to obtain through setting, when applied, a pre-trained optimization module is deployed in the processing module, and the optimization module is used to improve the control accuracy of the valve.

[0057] Specifically, the optimization module is constructed based on a neural network and a particle swarm algorithm;

[0058] The valve control test is carried out using different data combinations of frequency, duty cycle, and low level, and the corresponding adjustment time and control error are collected to form a data set. After collecting enough data, part of the data is used as the training set of the neural network, and the other part is used as the prediction set;

[0059] The essence of the particle swarm algorithm is to simulate the process of bird predation, which is used to optimize the neural network to obtain the global optimal solution and overcome the defect of the slow operation of the neural network;

[0060] After the parameters of the neural network are optimized by the particle swarm algorithm, the prediction error is small, which can improve the control accuracy and response time while avoiding overshoot.

[0061] In the several embodiments provided in this application, it can also be implemented in other ways. The functional modules in the various embodiments of the present invention can be integrated together to form an independent part, or each module can exist independently, or two or more modules can be integrated to form an independent part.

[0062] If the functions are implemented in the form of software function modules and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on such understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, which is stored in a storage medium and includes several instructions to enable a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the methods described in various embodiments of the present invention. It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.

For those skilled in the art, the present invention may have various changes and variations.

Any person skilled in the art can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
