In some embodiments of the present disclosure, the interaction device 103 is further configured to receive setting information about the plurality of valve banks 1020 input by a user, and the control device 104 is configured to control the plurality of valve banks 1020 to open in sequence according to an irrigation control strategy corresponding to an irrigation control mode input by the user and the setting information about the plurality of valve banks 1020, where each valve bank 1020 includes at least one valve selected from the plurality of valves 102 and controlled to open and close simultaneously, and the opening time intervals of any two valve banks 1020 do not overlap.

Fig. 2 is a schematic diagram of a setup interface of the interaction device 103 with respect to a plurality of valve blocks 1020 according to some exemplary embodiments of the present disclosure. This interface provides the selection setting about 4 valves (numbering is valves one to valves four respectively), and the user can be according to the liquid manure irrigation demand that different planting districts planted the crop, and nimble selection needs the valves that the valves and the valves that the valves contain that use, for example, can select 4 valves all to participate in the liquid manure irrigation to for valves one selection No. 1 valve to No. 4 valve, for valves two selection No. 5 valves to No. 8 valve, for valves three selection No. 9 valves to No. 12 valve, for valves four selection No. 13 valves to No. 16 valves. For example, 2 valve groups are selected to participate in water and fertilizer irrigation, and the valves from No. 1 to No. 5 are selected for the first valve group, and the valves from No. 6 to No. 8 are selected for the second valve group. Further examples of selection and combination of valve sets and valves are not listed here.

After the valve group is set, all the valves contained in the valve group are controlled to be opened and closed simultaneously. In the following description herein, the opening of the valve block, i.e. the opening of the respective valves comprised by the valve block, and the closing of the valve block, i.e. the closing of the respective valves comprised by the valve block. As shown in fig. 1, taking the example that all of the 4 valve banks 1020 participate in the irrigation of the liquid manure, the control device 104 controls the 4 valve banks 1020 to be sequentially opened, for example, first controls the first valve bank to be opened through the setting, controls the second valve bank to be opened through the setting after the first valve bank is closed, controls the third valve bank to be opened through the setting after the second valve bank is closed, and controls the fourth valve bank to be opened through the setting after the third valve bank is closed. The opening time intervals of any two valve banks 1020 are not overlapped, that is, any two valve banks 1020 are not in the opening state at the same time.

This embodiment provides more individualized, the irrigation of pertinence and selects for the user, and the user can combine local weather season, planting environment, different planting district to plant the demand condition of crop to liquid manure, sets up the valves in a flexible way to provide accurate liquid manure differential irrigation for planting the crop, like this, not only can improve farming's output benefit, can improve the efficiency that liquid manure irrigated moreover, reduce the cost of management operation.

The liquid manure irrigation control system 100 includes a plurality of irrigation control modes, and the interactive device 103 provides the plurality of irrigation control modes for user selection input. In some embodiments of the present disclosure, the plurality of irrigation control modes includes at least two of a time control mode, a flow control mode, a cyclic control mode, and an illumination control mode, wherein each irrigation control mode corresponds to an irrigation control strategy.

The following is an exemplary description of the irrigation control strategy in these irrigation control modes, and some specific examples are illustrated in which the user sets 4 valve banks with reference to the aforementioned setting.

In some embodiments, the plurality of irrigation control modes includes a time control mode, and the control device 104 is configured to: in response to the input irrigation control mode being the time control mode, acquiring at least one irrigation starting time input by a user, and respectively corresponding set starting durations when a plurality of valve banks 1020 are sequentially opened once after each irrigation starting time is started; and controlling the plurality of valve banks 1020 to be opened once in sequence from each irrigation start time and to be closed after the corresponding set opening duration.

For example, the irrigation start time set by the user is 6 irrigation start times of 8:00, 10:00, 12:00, 14:00, 16:00 and 18:00 respectively, after each irrigation start time is started, the set opening time lengths of the first valve group and the second valve group are 5 minutes respectively, and the set opening time lengths of the third valve group and the fourth valve group are 10 minutes respectively. The control device 104 will automatically control 4 valve banks 1020 to be sequentially opened according to the sequence of valve bank one to valve bank four at each irrigation start time and to be closed after the corresponding set opening duration, and the opening time intervals of two valve banks 1020 that are successively opened are not overlapped. For example, at 8 am, the valve group is closed after the first valve group is opened for 5 minutes, then the second valve group is closed after the second valve group is opened for 5 minutes, then the third valve group is closed after the third valve group is opened for 10 minutes, and then the fourth valve group is closed after the fourth valve group is opened for 10 minutes; repeat the irrigation process at 10 am, and so on.

Considering the difference of temperature, humidity, illumination conditions and the like at different times in a day, in some application scenarios, the set opening duration set by the user for the same valve block 1020 can be different according to different irrigation starting times, and can be flexibly set according to requirements. For example, the valve group is set to have a set on-time of 5 minutes at 8 am and a set on-time of 8 minutes at 12 pm.

In some embodiments, the plurality of irrigation control modes includes a flow control mode. In some embodiments, as shown in fig. 3, the liquid manure irrigation control system 100 further comprises a flow rate detection device 105 configured to detect an opening flow rate of each valve block 1020 of the plurality of valve blocks 1020. The control device 104 is also connected to a flow detection means 105 configured to: responding to the input irrigation control mode being a flow control mode, acquiring at least one irrigation starting time input by a user, and respectively starting the corresponding set starting flow after each irrigation starting time starts by the plurality of valve banks 1020 in sequence; and, starting from each irrigation start time, controlling the plurality of valve banks 1020 to be sequentially opened once and closed after reaching the corresponding set opening flow rate.

The control strategy of the flow control mode is different from that of the time control mode in that the valve group is closed when the flow of the valve group reaches the corresponding set opening flow. The user can open the flow according to the setting that the different planting crops were nimble to be set up the valves to the irrigation flow demand of liquid manure, for example, to the planting district of the great planting crop of liquid manure demand, set up the setting that its corresponds the valves and open the flow great relatively, to the planting district of the less planting crop of liquid manure demand, set up the setting that its corresponds the valves and open the flow less relatively. Similarly, considering the difference of temperature, humidity, illumination condition etc. of different times in a day, under some application scenarios, to different irrigation starting times, the flow can be different for setting opening of the same valves by the user, and can be flexibly set according to the demand. For example, the valve set-up opening flow rate at 12 pm is greater than the set-up opening flow rate at 8 am.

In some embodiments, the plurality of irrigation control modes includes a cyclical control mode, and the control device 104 is configured to: responding to the input irrigation control mode being a cyclic control mode, acquiring at least one irrigation time interval input by a user, and sequentially opening a plurality of valve banks 1020 once in a round of irrigation to respectively correspond to a set opening time and a set interval time, wherein the plurality of valve banks 1020 are sequentially opened once for a round of irrigation; and, in each irrigation time interval, controlling the plurality of valve banks 1020 to be cyclically opened according to a set interval duration and to be closed after experiencing a corresponding set opening duration, respectively.

For example, one of the irrigation time intervals input by the user is 10: 00-11: 00 am, the set opening durations of the first valve bank and the second valve bank are respectively 3 minutes, the set opening durations of the third valve bank and the fourth valve bank are respectively 6 minutes, and the set interval duration is 1 minute, at 10 am, the control device controls 4 valve banks to be opened circularly according to the following modes: the valve group is closed after being opened for 3 minutes, the valve group II is opened after 1 minute and closed after 3 minutes, the valve group III is opened after 1 minute and closed after 6 minutes, the valve group IV is opened after 1 minute and closed after 6 minutes, the valve group III is opened after 1 minute and closed after 3 minutes, the valve group II is opened after 1 minute and closed after 3 minutes, and the valve group … … is circulated until all the valve groups are controlled to stop irrigation at 11 am. This embodiment can realize the circulation differential irrigation of different planting areas.

In some embodiments, the plurality of irrigation control modes includes an illumination control mode, and as in some embodiments shown in fig. 3, the liquid manure irrigation control system 100 further includes an illumination detection device 106 configured to detect an outdoor illumination accumulation. The control device 104 is further connected to an illumination detection apparatus 106, configured to: in response to the input that the irrigation control mode is the illumination control mode, acquiring at least one irrigation time interval input by a user, wherein the illumination cumulative quantity threshold value, the set opening duration corresponding to one time of sequentially opening the plurality of valve banks 1020 in one round of irrigation and the minimum interval duration of two adjacent rounds of irrigation are respectively obtained, and the plurality of valve banks 1020 are sequentially opened for one round of irrigation; and in each irrigation time interval, in response to that the outdoor illumination cumulative amount reaches the illumination cumulative amount threshold value and the interval duration from the last round of irrigation (i.e., the time interval from the end of the last round of irrigation to the start of the next round of irrigation) is not less than the minimum interval duration, controlling the plurality of valve sets 1020 to be sequentially opened once and respectively closed after the corresponding set opening duration, and controlling the outdoor illumination cumulative amount of the illumination detection device 106 to be cleared.

For example, one of the irrigation time intervals input by the user is 10: 00-14: 00, the set opening time lengths of the four valve banks are respectively 10 minutes, and the minimum interval time length of two adjacent rounds of irrigation is 5 minutes. Starting from 10 am, the illumination detection device 106 starts to detect the outdoor illumination accumulation amount and the initial value is zero, and assuming that the outdoor illumination accumulation amount reaches the illumination accumulation amount threshold value for the first time at 10:30, the control device 104 controls the 4 valve banks to be opened in the following manner: the valve group I is opened for 10 minutes and then closed, the valve group II is opened for 10 minutes and then closed, the valve group III is opened for 10 minutes and then closed, and the valve group IV is opened for 10 minutes and then closed (the closing time of the valve group IV is 11: 10). The control device 104 also controls the outdoor light accumulation amount of the light detection apparatus 106 to be cleared at the same time as the valve group is opened (i.e., 10: 30).

Since the outdoor illumination accumulation amount of the illumination detection device 106 is cleared while the first valve group is opened, the illumination accumulation amount of the illumination detection device 106 is continuously increased in the process of sequentially opening the first valve group to the fourth valve group. Assuming that the cumulative amount of outdoor light reaches the cumulative amount of light threshold again at 11:20 (the time interval from the closing time 11:10 of the valve group four is longer than the minimum interval time by 5 minutes), the control device 104 controls 4 valve groups to open a round of irrigation again in the above manner. Assuming that at 11:08 (valve group four is still open, one round of irrigation has not ended) or 11:12 (the time interval from the closing time of valve group four, 11:10, is less than the minimum interval duration of 5 minutes), the cumulative amount of outdoor illumination reaches the cumulative amount of illumination threshold again, since the set value of the minimum interval duration is not reached, the control device 104 does not start the next round of irrigation, but starts one round of irrigation again at 11:15 (the set value of the minimum interval duration) in the above manner.

In some other embodiments of the present disclosure, the minimum interval duration may also be defined in other ways by equivalent conversion, for example, defining the minimum interval duration as the time interval from the last round of irrigation to the next round of irrigation, for example defining the minimum interval duration as 45 minutes (equivalent to the above-mentioned minimum interval duration being 5 minutes). Thus, the minimum interval duration is equal to the sum of the total time required for the sequential activation of the 4 valve groups and the equipment cooling and reaction delay times, and the course of the system is in accordance with the above description.

Because outdoor illumination cumulant may have great fluctuation because of weather conditions (such as too strong illumination, stream cloud shielding and the like), the reasonable setting of the minimum interval duration can avoid some hardware equipment such as the liquid manure machine 101 and the like from being started and stopped frequently, thereby ensuring the service life of the system and ensuring the high-efficiency, reasonable and accurate operation of the system.

As shown in fig. 3, the water and fertilizer irrigation control system 100 according to some embodiments of the present disclosure further includes a ph value detection device 107 and a conductivity detection device 108, and the control device 104 is further connected to the ph value detection device 107 and the conductivity detection device 108. The control device 104 is further configured to: in response to the fact that the pH value of the output water fertilizer is out of the pH value threshold range, the flow state of the water inlet pipeline 1011 and/or at least one fertilizer inlet pipeline 1012 is adjusted; and, in response to the conductivity of the output water fertilizer being outside of the conductivity threshold range, adjusting the flow state of water inlet line 1011 and/or at least one fertilizer inlet line 1012.

In this embodiment, the system can automatically adjust the flow states of the water inlet pipeline 1011 and the fertilizer inlet pipeline 1012 according to the ph value and the conductivity of the water fertilizer output by the water fertilizer machine 101, so that the relevant parameters of the output water fertilizer can meet the target requirements, and a more accurate water fertilizer irrigation effect can be obtained. For example, in some regions, the water of the irrigation water source is naturally weakly acidic, plants in the planting region need weakly alkaline fertilizers, and when the system detects that the pH value of the water fertilizer output by the water fertilizer machine 101 deviates from the pH value threshold range, the flow of the water inlet pipeline 1011 and/or some fertilizer inlet pipelines 1012 can be automatically finely adjusted, so that the pH value of the output water fertilizer reaches the target requirement.
