In one embodiment of the invention, the inside of the greenhouse is divided into 9 sections according to the area, wherein the sections are numbered as a No. 1 section, a No. 2 section and a No. 9 section. As shown in fig. 3. In each interval, an independent temperature sensor, a humidity sensor and an illumination intensity sensor are distributed, and a light supplement lamp, a gas-water heat exchanger and a humidifier are arranged at proper positions of each interval.
Fig. 4 is a flowchart of a PLC control procedure of the internal climate of the nursery greenhouse according to the present invention, which includes:
s501, collecting data of each temperature sensor, each humidity sensor and each illumination intensity sensor, and respectively judging whether the temperature, the humidity and the illumination intensity of each interval are higher or lower.
The PLC controller 500 includes a memory including values of set temperature, humidity, and illumination intensity, and the PLC controller 500 periodically and cyclically acquires data of each sensor, compares the values set in the memory, and determines whether the temperature, humidity, and illumination intensity of each section in the current greenhouse are appropriate.
S502, the PLC500 automatically controls the humidifier with proper humidity and higher humidity to be in a closed state; and controlling the humidifier with the lower humidity interval to be in an open humidifying state.
A plurality of humidifiers or spraying irrigation equipment are distributed in each area in the greenhouse, and the humidifier or the spraying irrigation equipment is started when the area needs to be humidified.
S503, the PLC controller 500 automatically controls the light supplement lamp with proper illumination intensity or in a higher section to be in an off state, and the light supplement lamp in a lower section to be in an on state.
A plurality of LED light supplement lamps are distributed in each area in the greenhouse, and are automatically started under the control of the PLC when the illumination intensity is insufficient.
S504, the PLC500 automatically and comprehensively calculates the overall temperature in the closed space of the greenhouse according to the temperature of each interval; and judging whether the temperature in the greenhouse is higher or lower according to the state of the overall temperature, and calculating the required water temperature in the gas-water heat exchanger according to the requirement of the overall temperature.
For example, the temperature of each area in the greenhouse is about 10 degrees, the overall temperature in the closed space of the greenhouse is 10 degrees through calculation, and the proper temperature set in the storage is 15 degrees, so that the water temperature of flowing water in the gas-water heat exchanger needs to be increased. After the water temperature in the air-water heat exchanger is increased, the whole temperature in the greenhouse is increased along with the increase of the water temperature in the air-water heat exchanger, a time process is needed, so a slightly long time period is set as a water temperature adjusting period of the heat preservation water storage device, in each water temperature adjusting period of the heat preservation water storage device, measurement and calculation are carried out once to judge the whole temperature in the closed space of the greenhouse, whether the temperature of flowing water in the air-water heat exchanger needs to be adjusted or not is judged according to the whole temperature, and the temperature in the heat preservation water storage device is adjusted. For example, the water temperature adjustment period of the heat preservation reservoir is half an hour or an hour.
S505, when the water temperature in the gas-water heat exchanger is lower, the water temperature in the heat preservation water storage device is increased: controlling an electric heater in the heat-preservation water storage tank to be started and heating to a required temperature; or when the temperature of the water in the solar collector is higher, controlling the water to be supplemented to the water storage tank which is emptied properly, and then controlling the supplementing water to be supplemented to the solar collector.
For example, if the water temperature adjustment period of the heat preservation water reservoir is set to be once every half hour or one hour, the water temperature in the heat preservation water reservoir needs to be adjusted from 40 ° to 50 °, and the water temperature in the solar thermal collector is 80 °, then the PLC controller 500 controls the heat preservation water reservoir to discharge one quarter of water, and then supplies water in the solar thermal collector to the heat preservation water reservoir, so that the water temperature in the heat preservation water reservoir is increased to 50 °.
S506, when the water temperature in the gas-water heat exchanger is higher, the water temperature in the heat preservation water storage tank is reduced, and underground water or river water is controlled to be supplemented into the heat preservation water storage tank which is emptied properly.
For example, when the water temperature in the heat preservation water storage device is 50 degrees and needs to be adjusted to 40 degrees, the temperature of river water or underground water is 10 degrees, the water in the heat preservation water storage device is emptied by one fourth, and then the water is supplemented with the river water or the underground water until the heat preservation water storage tank is full, so that the water temperature can be adjusted to about 40 degrees.
The temperature of underground water is generally 10-15 degrees, so the internal temperature of the nursery house can be properly reduced to be below the outdoor temperature. For example, when the sun is exposed in the sun at noon in hot summer, the top of the greenhouse can be properly covered, and then the underground water flows through the gas-water heat exchanger to cool, so that a good artificial climate in the greenhouse is created, the continuous growth of plants in the greenhouse is facilitated, the yield is improved, and the cost is low.
In step S505 and step S506, the water drained from the heat-preserving reservoir can also be used for humidification and irrigation in the greenhouse.
In one embodiment, the method for executing the work flow of the PLC controller 500 shown in fig. 4 includes steps S501 to S504 all the time in a loop, and a timer is set to execute steps S505 and S506 every time a water temperature adjustment period elapses.
In another embodiment, the method for executing the work flow of the PLC controller 500 shown in fig. 4 includes steps S501 to S506 being executed in a cycle all the time, the temperature of the circulating water in the heat-preservation water reservoir and the gas-water heat exchanger being adjusted dynamically all the time, when the temperature in the greenhouse needs to be raised, the hot water with higher temperature is added to the heat-preservation water reservoir at a fixed speed, and part of the circulating water from the gas-water heat exchanger to the heat-preservation water reservoir is discharged at the same speed; when the temperature in the greenhouse needs to be reduced, cold water with lower temperature is added into the heat preservation water storage device at a fixed speed, and part of hot water from the air-water heat exchanger to the heat preservation water storage device is discharged at the same speed.
In one embodiment of the present invention, since the inside climate of the nursery house does not change drastically, a time period is set and the work flow of the PLC controller 500 shown in fig. 4 is sequentially performed according to the time period. For example, the method is executed once every 15 minutes or 45 minutes, the temperature, the humidity and the illumination intensity are sequentially collected every time, and the water temperature in the heat-preservation water storage tank, the humidifier and the light supplement lamp are sequentially controlled to be turned on.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
