[0006] Preferably, the downlink Hall element is electrically connected with a third break switch.
[0007] The present application provides a greenhouse cotton quilt automatic controller, which has the following advantages: no mechanical limit point, using inductive detection, cooperating with software to complete 4G communication, remote setting control, easy installation, low cost, remote alarm in case of failure, safe and reliable. It is realized by using Hall detection technology to realize uplink accurate limit and downlink accurate limit. If the upper limit and lower limit detection parts are damaged, the controller can stop running and report Hall fault, remote current display, current setting overload, short phase alarm. The advantages of low cost, easy installation, complete protection function, small program operation and the like can be used in the northern environment of 40 DEG C to 60 DEG C, which provides safety protection for energy saving, cost reduction and safe production of growers. It completely eliminates the accidents of throwing the greenhouse cotton quilt, the roller shutter machine, the roller shutter machine and the like. BRIEF DESCRIPTION OF DRAWINGS

[0010] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.
[0011] Please refer to Figure 1 The present application provides a technical solution: a greenhouse cotton quilt automatic controller, comprising a single-chip microcomputer 1, the single-chip microcomputer 1 is provided with three detection ports, the three detection ports are respectively electrically connected with a first uplink Hall element 2, a second uplink Hall element 3 and a downlink Hall element 4, the single-chip microcomputer 1 is electrically connected with a power module 5 and a wireless network 6.
[0012] The uplink terminal is respectively provided with two detection points, i.e. the first uplink Hall element 2 and the second uplink Hall element 3. Under normal circumstances, the first detection point of uplink, i.e. the first uplink Hall element 2, is detected, the roller shutter machine will automatically stop and automatically adjust the running time data. If the first detection point is damaged, the second detection point, i.e. the second uplink Hall element 3, will be detected, at this time, the roller shutter machine will stop and alarm.
[0013] When downlink, the downlink detection point, i.e. the downlink Hall element 4, is detected, the software will clear to the second section of data, and the roller shutter machine will stop when running to the second section of data. If the downlink detection point is not detected during running, the software will run according to the last data, and will alarm to show the Hall fault after running is completed.
[0014] Further, the first uplink Hall element 2 is electrically connected with a first break switch, the second uplink Hall element 3 is electrically connected with a second break switch and a Hall alarm.
[0015] Further, the downlink Hall element 4 is electrically connected with a third break switch.
[0016] Through the skilled in the art, the parts in the present case are sequentially connected, the specific connection and operation sequence should be referred to the following working principle, and the detailed connection means is the public known technology in the art, the following mainly introduces the working principle and process.
[0017] Embodiment: provided with uplink position detection (first uplink Hall element 2 and second uplink Hall element 3) and downlink position detection (downlink Hall element 4), both uplink and downlink adopt time timing control, automatically adjust data when reaching the upper part, automatically clear zero when downlink reaches a certain position, continue to run downward, stop if reaching the set data, if the detection part is damaged, the first uplink Hall element 2 or the downlink Hall element 4 does not detect the state, the controller stops and alarms, if the second uplink Hall element 3 appears alarm, the uplink control power will be cut off, all operations fail, can be transferred to manual state. The limit position is detected by the Hall element, which conveniently solves the automatic control of the greenhouse cotton quilt, uses 4G network, and can view the running data of the cotton quilt by using the mobile phone app (how to use the mobile phone is not the focus of this design, and it belongs to the existing technology, so the operation and function of the mobile phone end do not need to be introduced in detail), and automatically adjusts the data (cotton quilt winding up, winding down, automatically adjusting the running data), if the detection element is damaged, it can automatically alarm and prompt the Hall fault, the running state of the motor can be observed, and overload and open-phase alarm can be realized
[0018] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without limitation, an element preceded by "comprises a..." does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus.
