Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.

In a first aspect, an embodiment of the present invention provides a method for controlling a cultivation environment, where a cultivation environment corresponding to the cultivation environment includes at least one sensor, at least one execution device, and at least one touch screen; the at least one touch screen is configured to: providing a parameter configuration interface, and acquiring configuration parameters input by personnel on the parameter configuration interface, wherein the configuration parameters at least comprise an initial date for calculating the day age of the cultured animals.

It will be appreciated that the present solution may be directed to controlling the breeding environment of a variety of farmed animals, such as pigs, cattle, sheep, poultry, etc.

In the cultivation environment, various sensors, such as a temperature sensor, a humidity sensor, a negative pressure sensor, a carbon dioxide concentration sensor, an ammonia concentration sensor, an opening sensor of a window, and the like, are provided. Various culture environment parameters in the culture environment can be collected by utilizing the sensors.

The actuating device is a device capable of adjusting the temperature, humidity, negative pressure, air flow rate, etc. of the culture environment, and for example, a wet curtain capable of cooling, a heater capable of heating, a humidifier capable of increasing humidity, a fan capable of adjusting the air flow rate, a window capable of exchanging air, etc. may be used.

It can be understood that the cultivation environment parameters to be monitored are different for different cultivated animals, and therefore, the sensors used may be different and the corresponding execution devices may be different.

For example, a worker in a farm can input the birth date of the farmed animals, namely the initial date for calculating the age of the farmed animals on the parameter configuration interface of the touch screen, so that the age of the farmed animals can be calculated on the basis of the initial date.

Because the breeding environment required by breeding animals of different ages in days is different, the bearing capacity of the breeding animals of smaller ages in days, such as the animals just born, is poor, the required breeding environment is strict, and the bearing capacity of the breeding animals of larger ages in days is strong, so the required breeding environment is changed. Therefore, personnel can input the initial date on the touch screen, the day age can be calculated conveniently in real time, and a cultivation environment according with the day age is further provided for the personnel.

Referring to fig. 1, the control method provided by the embodiment of the present invention may include the following steps S1 to S3:

s1, determining the current day age of the cultured animals according to the initial date;

the control method provided by the embodiment of the invention can be realized by one control device, and in an actual scene, the control device can be realized by a Siemens S7-200 SMART programmable logic control module. The control device can be connected with the sensor, the execution equipment and the touch screen. Therefore, in S1, the control device may acquire the inception date from the touch screen, and then calculate the current day age of the farmed animals based on the inception date.

S2, generating a control instruction for each execution device according to the cultivation environment parameters acquired by the at least one sensor in real time and the cultivation environment requirements corresponding to the current age of the cultivated animals;

it can be understood that the breeding environment requirements required by the breeding animals at different ages in days are different, so that when the breeding environment is controlled, the breeding environment requirements corresponding to the current age in days need to be determined, meanwhile, the breeding environment parameters collected by the sensors at the current time are obtained from the sensors, and whether the current breeding environment parameters meet the breeding environment requirements corresponding to the current age in days is further judged, and when the breeding environment requirements corresponding to the current age in days do not meet, the breeding environment needs to be adjusted and controlled, so that a corresponding control instruction is generated for each execution device.

And S3, sending the control instruction to corresponding execution equipment so that the execution equipment performs corresponding operation according to the control instruction to adjust the breeding environment, so that the adjusted breeding environment meets the requirement of the breeding environment corresponding to the current age of the bred animals.

It can be understood that after the control instruction corresponding to each execution device is sent to the execution device, the execution device performs corresponding operation according to the control instruction, and further adjusts the cultivation environment, so that the adjusted cultivation environment meets the cultivation environment requirement corresponding to the current age of the day.

In specific implementation, besides the configuration parameters input on the touch screen, the current age of the day, the culture environment parameters collected by each sensor, such as the current temperature, humidity and the like, can be displayed on the touch screen, and the operating states of each execution device, such as which constant speed fans are in an on state, the working frequency of the frequency converter and the like, can also be displayed. Therefore, the method provided by the embodiment of the present invention may further include: and sending at least one of the current age of the day, the culture environment parameters acquired by the at least one sensor in real time and the current running state of the at least one execution device to the at least one touch screen for displaying.

In one embodiment, the sensors may include a temperature sensor for collecting the temperature of the culture environment, and the devices capable of adjusting the temperature include a constant speed fan, a speed adjusting fan, a wet curtain, a heater, a window and the like, so that the corresponding execution device includes at least one of the constant speed fan, a frequency converter, the wet curtain, the heater and the window, and the frequency converter is connected to the speed adjusting fan.

The wind speed of the constant-speed fan is constant, and only the control is required to be turned on or off. The frequency converter is connected with the speed regulation fan, and when the frequency converter is at different operating frequencies, the rotating speeds of the speed regulation fan are different, so that the frequency converter can be opened and closed, and the operating frequency of the frequency converter can be adjusted and controlled. The constant speed fan and the speed regulating fan can change the air flowing speed in the culture environment, and further can change the temperature in the culture environment.

The wet curtain is generally installed at the other side of the window, and air passes through the wet curtain to be evaporated and then is blown to each corner by a fan, so that the indoor temperature is rapidly reduced. The heater is a heating device, and is required to be heated when the temperature in the culture environment is too low.

The window body generally comprises an air window and a small window, and the small window is generally arranged at the position on the side edge and has a smaller area. The louvers are generally installed at a lower position and have a relatively large area, such as a louver. The window body is used for ventilation, and the temperature in the culture environment can be changed through ventilation.

At this time, referring to fig. 2, in S2, a control command is generated according to the cultivation environment parameters acquired by the sensor in real time and the cultivation environment requirements corresponding to the current age of the cultivated animal, and the specific process may include S21 to S22:

s21, determining the optimal cultivation temperature corresponding to the current age of the cultivated animals according to the current age of the cultivated animals and the corresponding relation between each age of the cultivated animals and the optimal cultivation temperature obtained in advance, and taking the optimal cultivation temperature corresponding to the current age of the cultivated animals as a target temperature;

the corresponding relationship between each age of the farmed animals and the optimal farming temperature can be expressed by a certain functional relationship, and the functional relationship can be called as a first functional relationship.

For example, through actual calibration, for a pig, the optimal breeding temperature is 30 ℃ on a birth date, 29 ℃ at 10 days old, 28 ℃ at 20 days old, and 26 ℃ at 40 days old. Through the calibration data, a linear straight line segment can be constructed in the coordinate system according to two end points (30, 0) and (29, 10) aiming at the change relation of the optimal cultivation temperature with the age of the day between 0 and 10 of the age of the day, a linear straight line segment can be constructed in the coordinate system according to two end points (29, 10) and (28, 20) aiming at the change relation of the optimal cultivation temperature with the age of the day between 10 and 20 of the age of the day, and a linear straight line segment can be constructed in the coordinate system according to two end points (28, 20) and (26, 40) aiming at the change relation of the optimal cultivation temperature with the age of the day between 20 and 40 of the age of the day. And then connecting all the straight line segments end to obtain a first functional relation.

The calibration data can be input on a parameter configuration interface of the touch screen, that is, the configuration parameters further include the optimal culture temperature corresponding to a preset number of days of age.

Based on the above example, the determining process of the first functional relationship roughly includes: constructing a corresponding linear relation according to each two adjacent days of the preset number of days and the optimal culture temperature corresponding to the two days respectively, wherein the linear relation is used for representing the linear change condition of the optimal culture temperature along with the days between the two days; and forming the first functional relation according to the linear relation corresponding to every two adjacent days in the preset number of days.

In S21, the current age of day is searched for the corresponding optimum culture temperature in the above correspondence, and the optimum culture temperature is set as the target temperature.

S22, generating a first control instruction for each execution device according to the difference between the target temperature and the culture environment temperature acquired by the temperature sensor and the tolerance temperature;

the first control instruction corresponding to the constant-speed fan is used for controlling the constant-speed fan to be turned on or turned off; the first control instruction corresponding to the frequency converter is used for adjusting the working frequency of the frequency converter so that the frequency converter can control the speed of the speed-adjusting fan; a first control instruction corresponding to the wet curtain is used for controlling the opening or closing of the wet curtain; a first control instruction corresponding to the heater is used for controlling the heater to be turned on or turned off; and the first control instruction corresponding to the window body is used for adjusting the opening degree of the window body.

That is, the target temperature and the temperature collected by the temperature sensor are compared, and the difference between the target temperature and the temperature is calculated. If the difference is less than the tolerance temperature, it indicates that the actual temperature is close to the target temperature, and no temperature adjustment may be performed. And if the difference is larger than or equal to the tolerance temperature, the difference is larger at the moment, and temperature adjustment is needed, so that a first control instruction for each execution device is generated.

In practice, the tolerance temperature can be set according to needs, for example, the tolerance temperature can be 0.5 for day ages of 0-10, 0.6 for day ages of 10-20, and 0.8 for day ages of 20-40, and it can be seen that the tolerance temperature is larger with the increase of day ages, which indicates that the bearing capacity of the farmed animals is stronger with the increase of day ages, and the control of the temperature can be gradually relaxed at this time.

It can be understood that, for the constant-speed fans, the first control instruction can control the opening or closing of the constant-speed fans, and usually, a plurality of constant-speed fans are arranged in one breeding environment.

Understandably, aiming at the frequency converter, the first control instruction can control the frequency converter to be opened or closed, the working frequency of the frequency converter can be controlled when the frequency converter is controlled to be opened, and then the rotating speed of the speed regulation fan can be adjusted, so that the air flowing speed in the breeding environment is changed, and the temperature in the breeding environment is changed.

It can be understood that the first control instruction of the wet curtain can control the opening or closing of the wet curtain, and when the actual temperature in the breeding environment is higher, the temperature can be reduced by opening the wet curtain. The first control instruction of the heater can control the heater to be turned on or off, and when the actual temperature is lower, the heater can be turned on, so that the temperature is increased.

It can be understood that the first control instruction of the window body can adjust the opening degree of the window body, and the ventilation condition can be changed by changing the opening degree of the window body, so that the temperature in the breeding environment is changed.

That is to say, the culture environment can be adjusted through the operation of one execution device or a plurality of execution devices, so that the temperature of the culture environment is close to the optimal culture temperature required by the current day age.

Further, the at least one executing device comprises a form; the at least one sensor further comprises an opening sensor for acquiring the current opening size of the window. That is, if a window is included in the implementing device, an opening sensor should be included in the sensor to collect the opening size of the window.

At this time, the generating process of the first control instruction for the form may include: and generating a first control instruction for the window according to the difference value between the target temperature and the culture environment temperature acquired by the temperature sensor, the allowance temperature and the current opening size acquired by the opening sensor.

That is to say, when generating the first control instruction, not only the difference between the target temperature and the actual temperature and the tolerance temperature need to be considered, but also the current opening size of the window at that time needs to be considered, and the first control instruction is generated on the basis of the current opening size, so as to adjust the opening of the window.

It will be appreciated that the foregoing is the regulation of temperature in the aquaculture environment.

In another embodiment, the at least one sensor comprises a humidity sensor for collecting the humidity of the culture environment; the corresponding at least one executing device comprises at least one of a constant speed fan, a frequency converter, a wet curtain and a humidifier, and the frequency converter is connected with a speed regulating fan.

It can be understood that when the constant speed fan is started, the air flow speed in the culture environment can be changed, and then the moisture in the air can be adjusted. The frequency converter can control the speed regulation fan to work when in work, and the speed regulation fan can adjust the air flow speed in the culture environment to different degrees when in different rotating speeds, so that the humidity in the culture environment can be changed to different degrees. The wet curtain can increase the humidity in the culture environment besides reducing the temperature. The humidifier can also increase the humidity in the culture environment.

At this time, referring to fig. 3, in S2, according to the parameters of the breeding environment collected by the at least one sensor in real time and the requirements of the breeding environment corresponding to the current age of the breeding animals, a control instruction for each execution device is generated, which specifically includes S23 to S24:

s23, determining the optimal cultivation humidity corresponding to the current age of the cultivated animals according to the current age of the cultivated animals and the corresponding relation between each age of the cultivated animals and the optimal cultivation humidity obtained in advance, and taking the optimal cultivation humidity as the target humidity;

the corresponding relation between each age of the cultivated animals and the optimal cultivation humidity is actually the change relation of the optimal cultivation humidity along with the age of the animals, and the relation can be expressed by a second functional relation.

For example, through actual calibration, for a pig, the optimal breeding humidity is 0.85 at birth date, 0.80 at age 10, 0.75 at age 20, and 0.70 at age 40. Through the calibration data, a linear straight line segment can be constructed in the coordinate system according to two end points (0.85, 0) and (0.80, 10) aiming at the change relation of the optimal cultivation humidity with the age of the day between 0 and 10 of the age of the day, a linear straight line segment can be constructed in the coordinate system according to two end points (0.80, 10) and (0.75, 20) aiming at the change relation of the optimal cultivation humidity with the age of the day between 10 and 20 of the age of the day, and a linear straight line segment can be constructed in the coordinate system according to two end points (0.75, 20) and (0.70, 40) aiming at the change relation of the optimal cultivation humidity with the age of the day between 20 and 40 of the age of the day. And then connecting all the straight line segments end to obtain a second functional relation.

The calibration data can be input on a parameter configuration interface of the touch screen, that is, the configuration parameters can also include the optimal cultivation humidity corresponding to the preset number of days and ages.

Based on the above example, the determining process of the second functional relationship roughly includes: constructing a corresponding linear relation according to each two adjacent ages in the preset number of ages and the optimal cultivation humidity corresponding to the two ages respectively, wherein the linear relation is used for representing the linear change condition of the optimal cultivation humidity between the two ages along with the ages; and forming the second functional relation according to the linear relation corresponding to every two adjacent days in the preset number of days.

In S23, the current age of day is searched for the corresponding optimum cultivation humidity in the above correspondence, and the optimum cultivation humidity is set as the target temperature.

S24, generating a second control instruction for each execution device according to the difference between the target humidity and the humidity of the culture environment collected by the humidity sensor and the allowable humidity;

the second control instruction corresponding to the constant-speed fan is used for controlling the constant-speed fan to be turned on or turned off; the second control instruction corresponding to the frequency converter is used for adjusting the working frequency of the frequency converter so that the frequency converter can control the speed of the speed-adjusting fan; a second control instruction corresponding to the wet curtain is used for controlling the opening or closing of the wet curtain; and the second control instruction corresponding to the humidifier is used for controlling the humidifier to be opened or closed.

That is, the target humidity and the humidity collected by the humidity sensor are compared, and the difference between the target humidity and the humidity is calculated. If the difference is less than the allowable humidity, it may indicate that the actual humidity is close to the target humidity, and humidity adjustment may not be performed. If the difference is larger than or equal to the tolerance humidity, the difference is larger at this moment, and the humidity needs to be adjusted, so that a second control instruction for each execution device is generated.

In practice, the tolerance humidity can be set according to requirements, for example, the tolerance humidity can be 0.02 for day age of 0-10, 0.02 for day age of 10-20, and 0.03 for day age of 20-40, and it can be seen that the greater the tolerance humidity is with the increase of day age, which means that the bearing capacity of the farmed animals is stronger with the increase of day age, and the control of humidity can be gradually relaxed.

It can be understood that, for the constant-speed fans, the second control instruction can control the opening or closing of the constant-speed fans, and usually, a plurality of constant-speed fans are arranged in one breeding environment.

Understandably, aiming at the frequency converter, the second control instruction can control the frequency converter to be opened or closed, the working frequency of the frequency converter can be controlled when the frequency converter is controlled to be opened, and then the rotating speed of the speed regulation fan can be regulated, so that the air flowing speed in the breeding environment is changed, and the humidity in the breeding environment is changed.

It can be understood that the second control instruction for the wet curtain can control the opening or closing of the wet curtain, and when the humidity in the culture environment is relatively low, the humidity in the culture environment can be increased by opening the wet curtain. And the humidifier can be controlled to be turned on or off according to a second control instruction of the humidifier, and when the humidity in the culture environment is lower, the humidifier can be turned on, so that the humidity in the culture environment is improved.

It is to be understood that the above is the regulation of humidity in the cultivation environment.

In yet another embodiment, the at least one sensor may include a concentration sensor for collecting undesirable gas concentrations in the aquaculture environment; the corresponding at least one executing device comprises at least one of a constant speed fan, a frequency converter and a window body, and the frequency converter is connected with the speed regulating fan.

The undesirable gas is a gas that is not beneficial to the growth of the farmed animals, for example, carbon dioxide, ammonia gas, etc., and thus the concentration sensor may include a carbon dioxide concentration sensor, an ammonia gas concentration sensor, etc.

Understandably, when the concentration of the bad gas is higher, the fan can accelerate the air flow speed in the culture environment, the opening degree of the window body can be increased, and the air flow is accelerated. Therefore, the corresponding executing device at this time may include a constant speed fan, a frequency converter connected to the speed-regulating fan, a window, and the like.

At this time, referring to fig. 4, the generating of the control instruction for each execution device according to the breeding environment parameters collected by the at least one sensor in real time and the breeding environment requirement corresponding to the current age of the breeding animals in S2 may include S25 to S26:

s25, determining the upper limit concentration of the bad gas corresponding to the current age of the farmed animals according to the current age of the farmed animals and the corresponding relationship between the current age of the farmed animals and the upper limit concentration of the bad gas, which is obtained in advance;

the correspondence relationship between each age of the farm animals and the upper limit concentration of the undesirable gas, which is obtained in advance, is actually a relationship in which the upper limit concentration of the undesirable gas varies with the age of the farm animals, and the relationship can be expressed by a third functional relationship.

For example, in practice, the upper limit concentration of the undesirable gas is 300 units on the day of birth, 400 units at the age of 10 days, 500 units at the age of 20 days, and 600 units at the age of 40 days for a farm animal such as a pig.

Through the calibration data, a linear straight line segment can be constructed in the coordinate system according to two end points (300, 0) and (400, 10) aiming at the change relation of the upper limit concentration of the harmful gas along with the age of the day between 0 and 10 of the age of the day, a linear straight line segment can be constructed in the coordinate system according to two end points (400, 10) and (500, 20) aiming at the change relation of the upper limit concentration of the harmful gas along with the age of the day between 10 and 20 of the age of the day, and a linear straight line segment can be constructed in the coordinate system according to two end points (500, 20) and (600, 40) aiming at the change relation of the upper limit concentration of the harmful gas along with the age of the day between 20 and 40 of the age of the day. And then connecting all the straight line segments end to obtain a third functional relation.

The personnel can input the calibration data on a parameter configuration interface of the touch screen, that is, the configuration parameters can also include the upper limit concentration of the undesirable gas corresponding to a preset number of days.

The upper limit concentration of the undesirable gas is the maximum concentration of the undesirable gas in the culture environment to ensure the healthy growth of the cultured animals. When the actual concentration is higher than the upper limit concentration, the growth rate of the cultured animals is affected, and even the health of the cultured animals is caused.

Based on the above example, the determining process of the third functional relationship may roughly include: constructing a corresponding linear relation according to every two adjacent days of the preset number of days and the upper limit concentration of the undesirable gas respectively corresponding to the two days, wherein the linear relation is used for representing the linear change condition of the upper limit concentration of the undesirable gas along with the days between the two days; and forming the third functional relation according to the linear relation corresponding to every two adjacent days in the preset number of days.

S26, generating a third control instruction for each execution device according to the difference between the upper limit concentration of the harmful gas corresponding to the current day age and the concentration of the harmful gas collected by the concentration sensor;

the third control instruction corresponding to the constant-speed fan is used for controlling the constant-speed fan to be turned on or turned off; the third control instruction corresponding to the frequency converter is used for adjusting the working frequency of the frequency converter so that the frequency converter can control the speed of the speed-adjusting fan; and the third control instruction corresponding to the window body is used for adjusting the opening degree of the window body.

It can be understood that the concentration of the undesirable gas in the culture environment is still within a reasonable range if the concentration of the undesirable gas collected by the concentration sensor is less than the upper limit concentration of the undesirable gas corresponding to the current age of the day by comparing the upper limit concentration of the undesirable gas corresponding to the current age of the day with the concentration of the undesirable gas collected by the concentration sensor. And if the concentration of the harmful gas collected by the concentration sensor is greater than or equal to the upper limit concentration of the harmful gas corresponding to the current age of the day, the concentration of the harmful gas in the culture environment at the moment is high, the difference between the upper limit concentration of the harmful gas corresponding to the current age of the day and the concentration of the harmful gas collected by the concentration sensor is calculated, and a third control instruction for each execution device is generated according to the difference.

It can be understood that, for the constant-speed fans, the third control instruction can control the opening or closing of the constant-speed fans, and usually, a plurality of constant-speed fans are arranged in one breeding environment. For example, the number of the constant speed fans which are started is increased, and the concentration of the bad gas in the culture environment can be reduced.

It can be understood that, for the frequency converter, the third control instruction can control the on or off of the frequency converter, and when the frequency converter is controlled to be on, the working frequency of the frequency converter can be controlled, so that the rotating speed of the speed-regulating fan can be adjusted, and the concentration of the undesirable gas in the breeding environment can be changed. For example, the concentration of the undesirable gas in the culture environment can be reduced by changing the working frequency of the frequency converter and further increasing the rotating speed of the speed-regulating fan.

It will be appreciated that for a window, the third control instruction may control the size of the opening of the window. For example, the opening size of the window is increased, so that the concentration of the undesirable gas in the culture environment can be reduced.

At this time, the generation process of the third control instruction for the form may include: and generating a third control instruction for the window according to the difference between the upper limit concentration of the harmful gas corresponding to the current day age and the concentration of the harmful gas collected by the concentration sensor and the current opening size collected by the opening sensor.

That is to say, when the third control instruction is generated, not only the difference between the upper limit concentration of the undesirable gas corresponding to the current age of the day and the concentration of the undesirable gas collected by the concentration sensor needs to be considered, but also the current opening size of the window at the time needs to be considered, and the third control instruction is generated on the basis of the current opening size, so as to adjust the opening of the window.

It will be appreciated that the foregoing is the adjustment of the concentration of undesirable gases in the aquaculture environment.

In yet another embodiment, the at least one sensor may include a negative pressure sensor for collecting a magnitude of negative pressure in the farming environment; the corresponding at least one executing device can comprise at least one of a constant speed fan, a frequency converter and a window body, wherein the frequency converter is connected with the speed-regulating fan.

In an actual scene, in order to ensure the healthy growth of the cultured animals, the air pressure in the culture environment is smaller than the air pressure outside the culture environment, that is, a negative pressure environment is formed inside the culture environment, but the negative pressure cannot be too small, otherwise, the cultured animals have some uncomfortable reactions, and therefore, the negative pressure in the culture environment needs to be kept within a certain range, so that the culture requirements can be met.

Aiming at the culture requirement of negative pressure, the sensor comprises a negative pressure sensor, and corresponding execution equipment can comprise a constant-speed fan, a frequency converter, a window body and the like, wherein the frequency converter is connected with a speed-regulating fan. The negative pressure in the culture environment can be changed by controlling the opening number of the constant-speed fans, changing the rotating speed of the speed-regulating fans and changing the opening degree of the window body.

At this time, referring to fig. 5, in S2, the generating a control command for each execution device according to the breeding environment parameters acquired by the at least one sensor in real time and the breeding environment requirements corresponding to the current age of the breeding animals may specifically include S27 to S28:

s27, determining the optimal cultivation negative pressure corresponding to the current age of the cultivated animals according to the current age of the cultivated animals and the corresponding relationship between each age of the cultivated animals and the optimal cultivation negative pressure obtained in advance, and taking the optimal cultivation negative pressure as a target negative pressure;

the corresponding relation between each age of the cultured animals and the optimal culture negative pressure is actually the change relation of the optimal culture negative pressure along with the age of the animals, and the relation can be called as a fourth functional relation expression.

Calibration data required to be used in the determination of the fourth functional relationship can be input on a parameter configuration interface of the touch screen, that is, the configuration parameters can further include the optimal cultivation negative pressure corresponding to the preset number of ages in days.

The process of determining the fourth functional relationship generally includes: constructing a corresponding linear relation according to each two adjacent ages in the preset number of ages and the optimal culture negative pressure corresponding to the two ages respectively, wherein the linear relation is used for representing the linear change condition of the optimal culture negative pressure along with the ages between the two ages; and forming the fourth functional relation according to the linear relation corresponding to every two adjacent days in the preset number of days.

In S27, the current age of day is searched for the corresponding optimal negative culture pressure in the above correspondence, and the optimal negative culture pressure is set as the target negative pressure.

S28, generating a fourth control instruction for each execution device according to the difference value between the target negative pressure and the negative pressure acquired by the negative pressure sensor and the allowance negative pressure;

the fourth control instruction corresponding to the constant-speed fan is used for controlling the constant-speed fan to be turned on or turned off; a fourth control instruction corresponding to the frequency converter is used for adjusting the working frequency of the frequency converter so that the frequency converter can control the speed of the speed-adjusting fan; and a fourth control instruction corresponding to the window body is used for adjusting the opening degree of the window body.

That is, the target negative pressure and the actual negative pressure collected by the negative pressure sensor are compared, so that the difference between the target negative pressure and the actual negative pressure is calculated, and if the difference is smaller than the tolerance negative pressure, the actual negative pressure is close to the target negative pressure, and the negative pressure regulation may not be performed at this time. However, if the difference is greater than or equal to the tolerance negative pressure, it indicates that negative pressure adjustment is required at this time, and therefore a corresponding fourth control command is generated for each of the execution devices.

In practice, the tolerance negative pressure is larger with the increase of the age of the day, which means that the farmed animals have stronger bearing capacity with the increase of the age of the day, and the control on the negative pressure can be gradually loosened.

It can be understood that, for the constant-speed fans, the fourth control instruction can control the opening or closing of the constant-speed fans, and usually, a plurality of constant-speed fans are arranged in one breeding environment.

Understandably, the fourth control instruction can control the frequency converter to be opened or closed, the working frequency of the frequency converter can be controlled when the frequency converter is controlled to be opened, and then the rotating speed of the speed-regulating fan can be regulated, so that the negative pressure in the breeding environment can be realized.

It will be appreciated that for a window, the fourth control command may adjust the opening of said window. For example, if the negative pressure is large, the opening degree of the window body can be increased, and the negative pressure of the culture environment is further reduced.

At this time, the generation process of the fourth control instruction for the form may include: and generating a fourth control instruction for the window according to the difference between the target negative pressure and the actual negative pressure acquired by the negative pressure sensor and the allowance negative pressure.

That is to say, when the fourth control instruction is generated, not only the difference between the target negative pressure and the actual negative pressure collected by the negative pressure sensor needs to be considered, but also the current opening size of the window at the moment needs to be considered, and the fourth control instruction is generated on the basis of the current opening size, so as to adjust the opening of the window.

It will be appreciated that the above is for regulating the negative pressure in the culture environment.

Of course, an alarm can be arranged in the breeding environment system and connected with the control device, and when the control device cannot adjust the breeding environment parameters to meet the requirements, the control device can control the alarm to give an alarm.
