Embodiment
First, as shown in figure 1, the double-membrane greenhouse includes the first layer heat-insulation layer 101 positioned at top, positioned at top and ground The first support 103 of second layer heat-insulation layer 102, support first layer heat-insulation layer between face and the second of support second layer heat-insulation layer Support 104.As shown in figure 1, first support 103 may be supported in second support 104.Between second layer heat-insulation layer and ground Two spaces 106 are the growing space of crops.The first space 105 between first layer heat-insulation layer and second layer heat-insulation layer is buffering Space.As described below, in the present invention, it will using the first space come the tune that is become more meticulous to the humiture of second space Whole, this will be specifically described below.
According to one embodiment, the variable volume of first space and second space.That is, described first support it is vertical Support bar in ground is expansion link, and the support bar perpendicular to ground of second support is equally expansion link.According to a reality Example is applied, the expansion link is automatic telescopic link, can be controlled by extension and contraction control motor.
Include Temperature Humidity Sensor 205,206,207 referring to Fig. 2, the automatic control system of the double-membrane greenhouse in the lump.Institute Stating Temperature Humidity Sensor includes three groups, and first group of Temperature Humidity Sensor 205 is located in first space to sense the first space Temperature and humidity, second group of Temperature Humidity Sensor 206 be located in the second space to sense the temperature of second space and wet Degree, the 3rd group of Temperature Humidity Sensor 207 are located at the outside of double-membrane greenhouse to sense the temperature and humidity of exterior space.Hereinafter, For the facility of statement, this term being combined together of Temperature Humidity Sensor can be used, also can temperature in use sensor and The term of this separation of humidity sensor.
The automatic control system also includes membrane motor 203,204, and the membrane motor includes the first membrane motor 203 And second membrane motor 204.First membrane motor, which is fixed in first support, is used for the unlatching for controlling the first heat-insulation layer Or close, second membrane motor, which is fixed in second support, to be used to control being turned on and off for the second heat-insulation layer.
First and second membrane motor and first to the 3rd group of Temperature Humidity Sensor are connected to master controller 201.According to one embodiment, the extension and contraction control motor (not shown) is also connected to master controller.
The automatic control system also includes distribution box 202, be connected to master controller, the first and second membrane motors and Extension and contraction control motor.In addition, also include the alarm 208 being connected with the distribution box.
The master controller is used for the temperature and humidity signal for receiving Temperature Humidity Sensor transmission, and is stored according in system Multiple parameters send control signal to membrane motor, to realize control of leaking informaton for the double-membrane greenhouse.
The master controller includes memory, the multiple parameter of memory storage.
The volume in the first space and the volume of second space are stored with the memory.In one embodiment, institute The area coverage for stating double-membrane greenhouse is fixed, and it is empty to calculate first and second so as to the height based on the first and second supports Between volume.
In step 301, after the double-membrane greenhouse installs, user can adjust first by extension and contraction control motor The height of frame and second support.First support and the respective telescopic level of second support can be sent to by the extension and contraction control motor The master controller, the master controller is according to the default height of the first and second supports and stretching for the first and second supports Degree calculates the respective height of the first and second supports, so as to obtain the volume in first and second space and be stored in In reservoir.
In operation afterwards, as long as have adjusted the height of the first and second supports by extension and contraction control motor, note that The telescopic level of the support of master controller first and second, master controller will update accordingly the first space for being stored in its memory and The volume of second space.
In step 302, crops preference temperature at any time and wet is also store in the memory of master controller Degree.The preference temperature and humidity be can according to the characteristics of crops itself, it is residing season, current weather, following several What it weather forecast and experience and historical data determined jointly.That is, master controller can be according to these data predictions Go out the optimum temperature and humidity at following one month, one week future or even following one day each moment.Here suitable temperature Degree and humidity generally refer to the humiture of the temperature and humidity in second space, i.e. space where crop growth.Specific meter Calculation method is not the emphasis being discussed herein, therefore, is no longer extended here.
In step 303, second group of temperature sensor can send out the temperature and humidity sensed every a sampling period Give master controller.
Certainly, second group of temperature sensor can be distributed in second space, master controller can calculate sensed it is multiple Temperature and humidity value of the average value of temperature and humidity as crops current environment.
Master controller makes comparisons the temperature and humidity value of current environment with current preference temperature and humidity.As described above, The preference temperature of any time and suitable humidity value are store in the memory.Master controller can obtain from memory should Value.
Under temperature control mode, the temperature value of current environment is the current temperature value of second space and suitable temperature by master controller Angle value is made comparisons, and calculates difference between the two.
In step 304, judge the difference whether in temperature difference allowed band.The temperature difference allowed band refers to agriculture The growth of crop will not bring the temperature gap scope of influence.For example, the temperature difference allowed band is, for example, 0.2 degree Celsius.Institute Temperature difference allowed band is stated also to be stored in the memory.And the temperature difference allowed band is also based on the spy of crops itself Point, residing season, current weather, following several days weather forecast and experience and historical data and determine.
If the difference is in temperature difference allowed band, master controller does not send signal to the first and second wound membranes electricity Machine, that is, maintain current state, and this method terminates.
When the difference is not in temperature difference allowed band, in step 305, master controller judges that first layer is incubated Layer and the current state of second layer heat-insulation layer, and be turned on and off according to the state using different policy control heat-insulation layers, As described below.
If first layer heat-insulation layer and second layer heat-insulation layer are all closure state, master controller is to first group of TEMP Device sends signal to obtain the current temperature value in the first space, current according to the current temperature value in the first space, second space Temperature value, the volume in the first space and second space and temperature invasin calculate the temperature value of second space with it is suitable Difference between temperature value reaches the time needed for first in temperature difference allowed band, if the time needed for first is in first Between in allowed band, then the master controller sends control signal to control the second membrane motor to open second layer heat-insulation layer.Institute Stating the calculation formula of the time needed for first can design according to aerodynamic relative theory, repeat no more here.
The growth that the very first time allowed band refers on crops will not bring the time allowed band of influence.Also It is to say, although the temperature of second space is not suitable for crops in this time allowed band, the growth to crops will not Influence is brought, but influence is likely to result in more than this time, the very first time allowed band can be arranged as required to, hereafter In mention second and the 3rd time allowed band it is identical with the definition of very first time allowed band, only value is probably not With, that is to say, that different values is may be configured as according to different situations.For example, it is assumed that can be by second space in 20 minutes Temperature be adjusted to temperature in temperature difference allowed band, and very first time allowed band is half an hour, then can only be opened Second layer heat-insulation layer, without first layer heat-insulation layer is also opened.So, because first layer heat-insulation layer is in closure state, this Sample not only make use of the relatively stable air of the temperature and humidity in cushion space i.e. the first space, i.e., will not be by extraneous unstable Determine the influence of air, then can more relievedly to think that suitable temperature will necessarily be reached within the time needed for first, And this practice for slowly changing temperature will not bring larger impact to crops, can more be finely controlled crops Environment and crops are looked after more preferably.
As can be seen here, the technical program make use of the sky in the first space between first layer heat-insulation layer and the second heat-insulation layer Gas more subtly adjusts the air in second space.
In order to reduce energy consumption, due to can relievedly think that preference temperature can be reached after the time needed for first, then Within the time needed for described first, the temperature sensed is no longer sent to master controller by second group of temperature sensor. When after the time needed for described first, temperature that second group of temperature sensor will sense further according to the sampling period set before Degree is sent to master controller.
In one embodiment, the master controller is not further within the time needed for first is acted.Described After the time needed for first, if second group of temperature sensor is sent between the temperature value of master controller and suitable temperature Difference in temperature difference allowed band, the master controller sends control signal and protected with controlling the second membrane motor to close the second layer Warm layer.
In another embodiment, if after time needed for first, second group of temperature sensor is sent to master controller Temperature value and suitable temperature between difference still without in temperature difference allowed band, then further controlled, that is, held Trade first layer heat-insulation layer close and second layer heat-insulation layer open when temperature control.
As described above, the time needed for described first is if it exceeds very first time allowed band, and this explanation only opens the Two layers of heat-insulation layer are not sufficient to ensure that crops can obtain required temperature in reasonable time, at this moment, open the second layer and protect It may also need to open first layer heat-insulation layer while warm layer.The master controller can send control signal to control the second wound membrane Motor opens second layer heat-insulation layer.So as to be closed in first layer heat-insulation layer and the state of second layer heat-insulation layer unlatching.
As described above, when the time needed for described first if it exceeds very first time allowed band, or described first Second group of temperature sensor is sent to master control after time of the required time in very first time allowed band but needed for first When difference between the temperature value of device processed and suitable temperature is still without in temperature difference allowed band, first layer heat-insulation layer can be controlled Closure state is made as, and second layer heat-insulation layer can be controlled as opening；Or judge difference not in temperature in step 304 Find that the first heat-insulation layer is in closure state and the second heat-insulation layer is in opening after in poor scope；In general, both In the case of, the first heat-insulation layer is in closure state and the second heat-insulation layer is in opening.At this moment, master controller is warm to first group Spend sensor and send signal to obtain the current temperature value in the first space, to the 3rd group of temperature sensor send signal to obtain outside The current temperature value in portion space, the opening after being opened according to the current temperature value of exterior space, intensity of illumination, first layer heat-insulation layer The volume and temperature of the current temperature value of the current temperature value in area, the first space, second space, the first space and second space The difference that calculates between the temperature value of second space and suitable temperature value of degree invasin reaches in temperature difference allowed band the Time needed for two, if the time needed for second is in the second time allowed band, the master controller sends control Signal with control the first membrane motor open first layer heat-insulation layer.Second time allowed band is determined with very first time allowed band Justice is identical, and only their own value may be different.Further, since second layer heat-insulation layer is opening, then Ke Neng One space at this moment when calculating the time needed for second, can dispense the first space mesh as with the temperature of second space being This parameter of preceding temperature value.
In the time range needed for second operation of second group of temperature sensor can with the time range needed for first Interior operation is identical, also can be different.Since after opening first layer heat-insulation layer, the variable factor of the condition such as extraneous temperature and illumination It is larger.After the time needed for second, master controller can control the first and second membrane motors to close first layer and the second layer Heat-insulation layer.
If the time needed for second is not in the second time allowed band, this explanation is by opening first layer and second Layer heat-insulation layer can not meet the needs of crops, then at this moment master controller can send a signal to alarm, be carried to user It is abnormal, it is necessary to manual intervention that temperature displaying function automatically controls appearance.
If first layer heat-insulation layer and second layer heat-insulation layer are all opening, master controller sends control signal simultaneously To the first and second membrane motors to close first layer heat-insulation layer and second layer heat-insulation layer.It is main after the 3rd time allowed band Controller obtains the current temperature value of second space and made comparisons with preference temperature value, calculates difference between the two, judges The difference does not make action whether in temperature difference allowed band if in temperature difference allowed band；Otherwise, circulation is held again Row step described above.Wherein, as described above, the definition phase of the 3rd time allowed band and very first time allowed band Together, that is to say, that the crops in this time allowed band in second space can bear current temperature, will not be to it Growth impacts.The amount of calculation and the traffic of system can be reduced by adding the 3rd time allowed band, because in this time Each component of interior system can not act.
Explanation has been made to the example implementation of the present invention by taking temperature as an example above.In practice for humid control and such as This.That is, the control above for temperature can directly be replaced with to the control for humidity, i.e., obtain second using humidity sensor The humidity value in space is simultaneously made comparisons to carry out the next control to humidity with Appropriate.Here repeat no more.Further, it is also possible to It is controlled simultaneously according to both temperature and humidities, you can think that both set weight, the value that both are calculated adds respectively The control strategy for two heat-insulation layers is judged after weight.This is a following research direction of this programme, to realize more The crop environment control to become more meticulous, is also no longer repeated here.
In addition to above-mentioned intelligentized control model, the master controller also has other various control patterns, user It can as needed be selected, these control models are introduced below.(upper and lower film here refers to above respectively One layer of heat preservation layer and second layer heat-insulation layer, similarly hereinafter)
