Description

Technical Field

[0001] This invention belongs to the field of humidifier control technology, specifically an ultrasonic humidifier control method. Background Technology

[0002] Factory cultivation is an important direction for the future development of edible fungi in my country. It refers to simulating the growth environment of edible fungi under controlled conditions. The relative humidity of the mushroom house is one of the most critical environmental factors and must be strictly controlled. Ultrasonic humidifiers are widely used due to their advantages such as high strength, small size, high efficiency, energy saving and environmental protection. Conventional control methods include: timer control - setting the working and turning times of the humidifier to control the humidification amount; atomization control - controlling by adjusting the number of ultrasonic transducers; humidity control - the humidifier will automatically work when the relative humidity is lower than the set value and automatically stop working when the relative humidity reaches the set value. The humidification demand of edible fungi is not constant throughout the entire cultivation and production cycle. When using timer control or atomization control, the grower's experience is required to manually modify the control parameters to meet the current humidification demand. When using humidity control, the humidifier's working state switches between fully on and fully off, resulting in poor control accuracy. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an ultrasonic humidifier control method to solve the problems of poor humidity control accuracy and the need for technicians to frequently modify parameters in order to achieve more accurate humidity control.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic humidifier control method, comprising a controller, wherein the controller includes two modes for selection: a local working mode and a remote working mode, and the control steps include:

[0005] S1. When working in local mode, a humidity transmitter is pre-connected to measure the humidity in the room and calculate the percentage of humidification based on the measured value and the set value.

[0006] S2. Set the total number of oscillators and the timing cycle of the humidifier;

[0007] S3. The controller automatically calculates the working status corresponding to each humidification percentage through the internal calculation formula, namely the number of humidifier oscillators and the running time.

[0008] S4. Obtain the results and start the humidifier. Generally, no modification to the relevant parameters is needed; the number of humidifier oscillators and the running time will vary with the percentage of humidification. Only when the humidification is significantly excessive should the total number of humidifier oscillators be reduced; or if the humidifier starts and stops too frequently, the timing cycle can be appropriately extended.

[0009] S5. When working in remote mode, connect a 0V-10V analog control signal, and the controller will convert the signal into a humidification percentage.

[0010] S6. Control the operation steps in S2-S4 through remote control.

[0011] When controlling the system in local operating mode, the following values ​​need to be set:

[0012] The humidity setting is 80%;

[0013] The value for the humidification blind zone is 2%;

[0014] The humidification deviation value is 10%;

[0015] The maximum humidification capacity is 90%;

[0016] The minimum humidification rate is 10%.

[0017] When the room humidity is less than or equal to the humidity setting value minus the humidification deviation (80% - 10% = 70%), the humidifier operates at its maximum humidification capacity of 90%.

[0018] When the room humidity is greater than or equal to the humidity setting value minus the humidification dead zone = 80% - 2% = 78%, the humidifier operates at its minimum humidification capacity of 10%.

[0019] When 70% > room humidity > 78%, the room humidity decreases proportionally. The higher the room humidity, the lower the humidifier's humidification output. When the room humidity is 74%, the humidifier operates at 50%.

[0020] The parameter values ​​that need to be set for remote control are:

[0021] The maximum humidification capacity is 90%;

[0022] The minimum humidification level is 10%.

[0023] When the control signal is ≤0V, the humidifier operates at the minimum humidification capacity of 10%.

[0024] When the control signal is ≥10V, the humidifier operates at its maximum humidification capacity of 90%.

[0025] When 10V > control signal > 0V, the larger the control power, the more humidifier it can humidify. When the control signal = 5V, the humidifier operates at 50%.

[0026] Firstly, an operating time parameter is introduced, which controls the number of humidifier oscillators and their operating time to correspond one-to-one with the humidification capacity from 0% to 100%.

[0027] Prior to this, the total number of ultrasonic humidifier transducers used in the mushroom house can be set and included in the calculation.

[0028] Prior to this, the humidifier incorporates timing cycle parameters and participates in the calculation.

[0029] The calculation process is as follows:

[0030] A1. Let the total number of humidifier vibrators be N1, the number of operating humidifiers be N2, and the percentage value be n, where n is an integer.

[0031] Calculate 100 / N1 = A, where A is the integer part of the quotient;

[0032] When n≤1×A, the number of humidifier oscillators running is N2=1;

[0033] When 1×A<n≤2×A, the number of humidifier oscillators operating is N2=2;

[0034] When 2×A<n≤3×A, the number of humidifier oscillators operating is N2=3;

[0035] When 3×A<n≤4×A, the number of humidifier oscillators operating is N2=4, and so on;

[0036] A2. The design cycle is T, the running time is T1, and the shutdown time is T2, all in minutes;

[0037] T1 = T / (N2 / N1) 100) n;

[0038] T2 = T - T1.

[0039] Prior to this, through the above calculation process, the humidification percentages of 1%, 2%, 3%...100% correspond to different humidifier oscillator operation numbers and operation times. When the humidification percentage = 0%, the humidifier is completely off.

[0040] Prioritize adjusting the total number of oscillators or the timing cycle if the actual control situation is not ideal, until the requirements are met.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] The control method of this application has two working modes: remote control mode and local control mode. When using remote control mode, the 0V-10V signal is automatically converted into a humidification percentage. When using local control mode, the humidification percentage is automatically calculated based on the relative humidity. The number of ultrasonic humidifiers in operation and the operation time change with the humidification percentage to adapt to the current humidification needs.

[0043] This method is adaptable to various numbers of ultrasonic transducers in humidifiers. The timing cycle is open and adjustable, and once the parameters are set, they do not need to be modified again, reducing labor costs. It achieves 0-100% proportional control of ultrasonic humidifiers, accurately controls the humidity in mushroom houses, improves the mushroom growth environment, and reduces labor costs. The ultrasonic humidifier uses the high-frequency vibration of the transducer to cause the water in the humidifier to be thrown off the water surface to produce drifting water mist, thus achieving the purpose of air humidification.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] This invention provides a technical solution: an ultrasonic humidifier control method, including a controller, wherein the controller includes two modes for selection: a local working mode and a remote working mode, and the control steps include:

[0049] S1. When working in local mode, a humidity transmitter is pre-connected to measure the humidity in the room and calculate the percentage of humidification based on the measured value and the set value.

[0050] S2. Set the total number of oscillators and the timing cycle of the humidifier;

[0051] S3. The controller automatically calculates the working status corresponding to each humidification percentage through the internal calculation formula, namely the number of humidifier oscillators and the running time.

[0052] S4. Obtain the results and start the humidifier. Under normal circumstances, there is no need to modify the relevant parameters. The number of humidifier oscillators and the running time will change with the percentage of humidification. Only when the humidification is obviously too large can the total number of humidifier oscillators be reduced, or the humidifier starts and stops too frequently can the timing cycle be appropriately extended.

[0053] S5. When operating in remote working mode, connect a 0V-10V analog control signal, and the controller will automatically convert the signal into a humidification percentage.

[0054] S6. Control the operation steps in S2-S4 through remote control.

[0055] The two control methods can be selected based on the site conditions. If the humidifier is completely independent and does not accept control from other control systems, the local control mode should be selected; if the humidifier is only used as a controlled device, the remote control mode should be selected.

[0056] Let's take the local control mode as an example.

[0057] The humidity transmitter is installed in the mushroom house to detect the room humidity and participate in the humidifier proportional control. In addition to the room humidity, the humidifier proportional control related parameters include humidity setpoint, humidification blind zone, humidification deviation, maximum humidification capacity, minimum humidification capacity, number of ultrasonic transducers, and timing cycle. Except for the room humidity, which is the actual detected value, all other parameters are settable.

[0058] After determining the operating mode and setting the relevant parameters, the program will automatically calculate the required percentage of humidification upon startup. The calculation logic is as follows: Figure 2 As shown;

[0059] When controlling the system in local operating mode, the following values ​​need to be set:

[0060] The humidity setting is 80%;

[0061] The value for the humidification blind zone is 2%;

[0062] The humidification deviation value is 10%;

[0063] The maximum humidification capacity is 90%;

[0064] The minimum humidification rate is 10%.

[0065] When the room humidity is less than or equal to the humidity setting value minus the humidification deviation (80% - 10% = 70%), the humidifier operates at its maximum humidification capacity of 90%.

[0066] When the room humidity is greater than or equal to the humidity setting value minus the humidification dead zone = 80% - 2% = 78%, the humidifier operates at its minimum humidification capacity of 10%.

[0067] When 70% > room humidity > 78%, and when room humidity = 74%, the humidifier operates at 50%.

[0068] Based on the actual total number of humidifier oscillators and the preset timing cycle, the number of humidifier oscillators that operate, as well as the working time and shutdown time, corresponding to humidification demand ranging from 1% to 100% are calculated.

[0069] The calculation process is as follows:

[0070] A1. Let the total number of humidifier vibrators be N1, the number of operating humidifiers be N2, and the numerator of the percentage value be n, where n is an integer.

[0071] Calculate 100 / N1 = A, where A is the integer part of the quotient;

[0072] When n≤1×A, the number of humidifier oscillators running is N2=1;

[0073] When 1×A<n≤2×A, the number of humidifier oscillators operating is N2=2;

[0074] When 2×A<n≤3×A, the number of humidifier oscillators operating is N2=3;

[0075] When 3×A<n≤4×A, the number of humidifier oscillators operating is N2=4, and so on;

[0076] A2. The design cycle is T, the running time is T1, and the shutdown time is T2, all in minutes;

[0077] T1 = T / (N2 / N1) 100) n;

[0078] T2 = T - T1.

[0079] Furthermore, through the above calculation process, the humidification percentages of 1%, 2%, 3%...100% correspond to different humidifier oscillator operation numbers and operation times. When the humidification percentage = 0%, the humidifier is completely off. If the actual control situation is not ideal, the total number of oscillators or the timing cycle is modified until the requirements are met.

[0080] The total number of humidifier oscillators is N1=6, the timing period is T=60 minutes, and the calculation results are shown in the table below;
