Specific embodiment
1 side of seedling cultivation greenhouse is provided with control room 2；
Seedling cultivation greenhouse lower part is provided with pillar 3, column upper section is provided with platform 4, and pot for growing seedlings 5 is arranged on platform；
It is provided with lower ventilation duct 6 between pillar, lower temperature sensor 7, lower ventilation duct and lower blower are housed on lower ventilation duct
The connection of 11 air outlets, lower blower are mounted on the lower part of control room, and air inlet is connected to electric heater 13；
It is provided with upper ventilation duct 8 in seedling cultivation greenhouse upper space, temperature sensor 9, upper ventilation duct are installed on upper ventilation duct
One end is connected to setting in the indoor upper fan 10 of control, and the air inlet of upper fan is connected to the upper section of electric heater；
The electric heater is divided into two sections, and every section is respectively arranged with heating element, is arranged at the intermediate position of electric heater
There is air inlet 12；
It is provided with PLC controller 14 in control room, PLC controller passes through upper fan motor control line 10.1 respectively and upper fan is believed
Number connection；
Lower blower control line 11.1 and lower blower signal communication；
Electric heater upper section control line 13.1 is connected to electric heater upper section heating element signal；
Electric heater lower section control line 13.2 is connected to electric heater lower section heating element signal；
Upper temperature sensor signal input line 9.1 is connected to upper temperature sensor signal；
Lower temperature sensor signal input line 7.1 is connected to lower temperature sensor signal.
The upper temperature sensor and lower temperature sensor are thermosensitive resistance type sensor.
Technical principle:
PLC controller has the function of that scanning signal data are handled, while there are also contact relay functions and logic to transport
Function and store function are calculated, it, being capable of opening by blower under input process control and upper fan in the control of seedling cultivation greenhouse temperature
It closes, determines that the condition of opening and closing is carried out according to the signal of temperature sensor, so opening when seedling cultivation greenhouse is low compared with preset temperature
Dynamic blower carries out hot wind supply, to improve the temperature of pot for growing seedlings or more, in fact, temperature requirement is different pot for growing seedlings up and down, just
Beginning sowing stage needs pot for growing seedlings temperature of lower relatively high, in favor of germination, after germination is broken ground, into cauline leaf
Growth phase then needs pot for growing seedlings upper temp to be higher than lower part, can just rice shoot be made to mushroom out, if pot for growing seedlings lower part temperature at this time
When degree is higher than top, rice shoot excessive growth will occur, be unfavorable for cultivating healthy and strong rice shoot, therefore added according to seedling growth phase sets
Hot program is very necessary.The present apparatus carries out process control to blower by PLC controller, and the temperature of sensor collection is believed
It number is handled, is then input in contact control circuit, open and close the operation process of blower, and can also by PLC controller
Electric heater upper end or lower end heating element fragmentary works or co-operation are controlled, to adapt to the reality of seedling cultivation greenhouse temperature requirement
Control.
The course of work:
Electric heater provides thermal energy, when upper and lower blower controls the opening and closing and operating of blower according to the processing of temperature sensor signal
Between, it carries out hot wind supply or stops hot wind supply, to adjust the nursery temperature of seedling cultivation greenhouse.
Feature:
Due to controlling opening and closing and the duration of runs of blower using PLC controller, and program is write according to seedling raising process, is input to
In PLC controller, it is achieved that the intelligent control of seedling cultivation greenhouse nursery, so that the rice shoot brought out reaches well developed root system, branch
Leaf is healthy and strong, and the effect of high survival rate.
