A kind of method using wound membrane control device described in the present embodiment to realize wound membrane, described method includes:
S1, temperature sensor obtains greenhouse temperature in real time, and the greenhouse temperature recorded is sent to controller；
S2, controller receives the greenhouse temperature that temperature sensor currently records, it is judged that described greenhouse temperature is with default
Temperature threshold A and the magnitude relationship of preset temperature threshold value B, if greenhouse temperature is more than or equal to preset temperature threshold value
A then controller sends to wound membrane motor opens wound membrane instruction, and continues to judge；If greenhouse temperature is less than presetting
Temperature threshold B, then controller sends cut out wound membrane instruction to wound membrane motor, and continues to judge.More detailed solution
Releasing explanation is:
(1), in step S2, if greenhouse temperature is more than or equal to preset temperature threshold value A, controller is to wound membrane electricity
Machine sends opens wound membrane instruction, realizes the most as steps described below:
A1, controller receives the greenhouse temperature that temperature sensor currently records, it is judged that and obtain described greenhouse temperature
Degree is more than or equal to presetting primary temperature threshold, then the wound membrane of opening sending described temperature threshold corresponding instructs, so
Rear entrance A2, while entering A2, after wound membrane motor receives instruction, performs wound membrane operation；
A2, after protecting against shock guard time, it is the biggest that controller continues to judge to connect the greenhouse temperature being currently received
In equal to next stage temperature threshold, open wound membrane instruction if it is, send to wound membrane motor, then repeat
A2, till greenhouse wound membrane is all turned on；Open wound membrane instruction if it is not, then do not send, return A1.
Described protecting against shock guard time is 10s.
(2) described preset temperature threshold value A includes three grades, particularly as follows:
Primary temperature threshold, correspondence is opened the one-level of greenhouse wound membrane and is opened wound membrane instruction；
Middle rank temperature threshold, correspondence is opened two grades of greenhouse wound membrane and is opened wound membrane instruction；

Described hysteresis temperature is arranged according to the demand of user.Described bias temperature for for 0.5 DEG C, described hysteresis temperature
It it is 1.0 DEG C.
(3) step S2, described greenhouse temperature is less than preset temperature threshold value B, then controller is sent out to wound membrane motor
Go out to close wound membrane instruction, realize the most as steps described below:
B1, controller receives the greenhouse temperature that temperature sensor currently records, it is judged that and obtain described greenhouse temperature
Less than preset temperature threshold value B, then send Guan Bi wound membrane instruction to wound membrane motor, subsequently into B2, enter B2
While, after wound membrane motor receives close command, perform to close wound membrane operation；
B2, after protecting against shock guard time, controller continues to judge to connect whether the greenhouse temperature being currently received is more than
Equal to preset temperature threshold value B, if it is, send Guan Bi wound membrane instruction to wound membrane motor, then repeat B2,
Till greenhouse wound membrane all closes；If it is not, then do not send Guan Bi wound membrane instruction, repeat B2.
