Description

Technical Field

[0001] The invention relates to a solar film roll fault detection and repair system, and belongs to the field of greenhouse intelligent control. Background Art

[0002] With the continuous advancement of agricultural technology, facility agriculture represented by greenhouses has developed rapidly. my country's greenhouse area, which mainly produces vegetables, has jumped to the first place in the world. Crops grow in greenhouses, which require greenhouses to adjust the temperature and humidity and ventilate the greenhouses by rolling and unrolling the film according to the different growth stages of the crops and the climatic conditions of the greenhouses.

[0003] At present, the degree of automation in most greenhouses is low, and the winding and unfolding of the film is mainly achieved by manual film rollers. With the continuous development of facility agriculture, the proportion of electric film rollers is increasing year by year, but the current electric film rollers cannot realize automatic fault detection and repair, and can only be inspected manually on site, which is very inconvenient. Summary of the invention

[0004] The purpose of the present invention is to provide a solar film roll fault detection and repair system to solve the problem of inconvenient detection of existing electric film rolls.

[0005] In order to solve the above problems, it is proposed to adopt a solar film roll fault detection and repair system, including an upper detection component, a lower detection component and two adjustment cam mechanisms. The adjustment cam mechanism is connected to the output shaft of the film roll drive motor. The upper detection component and the lower detection component are respectively arranged corresponding to the rotating cams of the two adjustment cam mechanisms, so that when the film roll drives the film roll shaft to reel in and release the film to the limit position, the upper detection component and the lower detection component are respectively triggered. The upper detection component and the lower detection component are both connected to the processor in the film roll, and the processor is connected to the host computer through a wireless transmission module. The processor or the host computer is also connected to a timing module, and the host computer is also connected to an alarm module.

[0006] In the above-mentioned fault detection and repair system, when it is necessary to start the film winder, the host computer sends a control signal to the processor through the wireless transmission module, and the processor starts the film winder drive motor to drive the film winder shaft to perform film collection or film release operations. At the same time, the timing module starts timing. When the film collection or release reaches the limit position within the set time, the raised contours of the two rotating cams respectively contact or approach the upper detection component or the lower detection component to trigger the detection component to send a signal to the processor. The processor uploads the signal to the host computer through the wireless transmission module. If the film collection or release does not reach the limit position within the set time, it means that the film winder or related equipment has a fault. At this time, the host computer cannot receive the detection signal uploaded by the processor within the set time, and the host computer controls the alarm module to sound an alarm to prompt the operator that a fault has occurred.

[0007] In the aforementioned fault detection and repair system, the upper detection component and the lower detection component are both contact or proximity sensors;

[0008] In the above-mentioned fault detection and repair system, the upper detection component and the lower detection component are both limit switches, the adjustment cam mechanism includes a rotating cam and a cam adjustment gear plate fixed coaxially with the rotating cam, the cam adjustment gear plates are drivingly connected to the output shaft of the film winding machine drive motor, the upper detection component and the lower detection component respectively include a status detection switch and a motor power-off switch, and each rotating cam is respectively provided with two raised contours, and the two raised contours correspond to the trigger status detection switch and the motor power-off switch respectively.

[0009] In the above-mentioned fault detection and repair system, the cam adjusting gear disc is connected to the output shaft of the film rolling device driving motor through a fixed-axis gear train, and the adjusting cam mechanism also includes a knob and a rotating shaft. The film rolling device also has an upper fixed plate and a lower fixed plate arranged in parallel, and the adjusting cam mechanism is arranged between the upper fixed plate and the lower fixed plate, and the knob and the cam adjusting gear disc are respectively fixed to the two ends of the rotating cam, and the cam adjusting gear disc and the rotating cam are rotatably arranged on the rotating shaft and can slide along the axial direction of the rotating shaft. One end of the rotating shaft is fixed to the lower fixed plate, and the outer end of the knob extends out through the knob hole on the upper fixed plate. A spring is sleeved on the rotating shaft, and the spring is pressed between the cam adjusting gear disc and the lower fixed plate.

[0010] Compared with the prior art, the present invention can timely discover faults in the working process of the film roll by setting upper and lower detection components and uploading them to the upper computer through wireless transmission mode, and promptly issue an alarm to remind the staff, which can effectively avoid further losses caused by the fault. The whole system runs stably and is easy to control, which greatly improves the intelligent control level of the greenhouse. The structural design of the adjustment cam mechanism also facilitates the adjustment of the upper and lower limits. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Example

[0016] Reference Figure 1 and Figure 2 The present embodiment provides a solar film roll fault detection and repair system, including an upper detection component 1, a lower detection component 2 and two position adjustment cam mechanisms 3. The upper detection component 1 and the lower detection component 2 are both contact or proximity sensors. The position adjustment cam mechanism 3 is connected to the output shaft of the film roll drive motor 4 in a transmission manner. The upper detection component 1 and the lower detection component 2 are respectively arranged corresponding to the rotating cams 31 of the two position adjustment cam mechanisms 3, so that when the film roll drives the film roll shaft to reel in and unreel the film to reach the limit position, the upper detection component 1 and the lower detection component 2 are respectively triggered. The upper detection component 1 and the lower detection component 2 are both connected to a processor 5 in the film roll, and the processor 5 is connected to a host computer 7 via a wireless transmission module 6. The processor 5 or the host computer 7 is also connected to a timing module 8, and the host computer 7 is also connected to an alarm module 9.

[0017] When it is necessary to start the film roll, the host computer 7 sends a control signal to the processor 5 through the wireless transmission module 6. The processor 5 starts the film roll drive motor 4 to drive the film roll shaft to perform film collection or film release operations. At the same time, the timing module 8 starts timing. When the film collection or film release reaches the limit position within the set time, the raised contours 311 of the two rotating cams 31 respectively contact or approach the upper detection component 1 or the lower detection component 2 to trigger the detection component to send a signal to the processor 5. The processor 5 uploads the signal to the host computer 7 through the wireless transmission module 6. If the film collection or film release does not reach the limit position within the set time, it means that the film roll or related equipment has a fault. At this time, the host computer 7 cannot receive the detection signal uploaded by the processor 5 within the set time. The host computer 7 controls the alarm module 9 to sound an alarm to prompt the operator that a fault has occurred. Example

[0018] Reference Figures 1 to 3 The present embodiment provides a solar film roll fault detection and repair system, including an upper detection component 1, a lower detection component 2 and two position adjustment cam mechanisms 3, the position adjustment cam mechanism 3 is connected to the output shaft of the film roll drive motor 4, the upper detection component 1 and the lower detection component 2 are respectively arranged corresponding to the rotating cams 31 of the two position adjustment cam mechanisms 3, so that when the film roll drives the film roll shaft to reel in and unwind the film to the limit position, the upper detection component 1 and the lower detection component 2 are respectively triggered, the upper detection component 1 and the lower detection component 2 are both connected to the processor 5 in the film roll, the processor 5 is connected to the host computer 7 through the wireless transmission module 6, and the host computer 7 is also connected to the timing module 8 and the alarm module 9.

[0019] In order to make the detection components run more stably and less prone to malfunctions, limit switches are selected for the upper detection component 1 and the lower detection component 2. The adjustment cam mechanism 3 includes a rotating cam 31 and a cam adjustment gear disk 32 coaxially fixed with the rotating cam 31. The cam adjustment gear disk 32 is transmission-connected to the output shaft of the film rolling device driving motor 4. The upper detection component 1 and the lower detection component 2 respectively include a status detection switch and a motor power-off switch, and each rotating cam 31 is respectively provided with two raised profiles 311, and the two raised profiles 311 correspond to the trigger status detection switch and the motor power-off switch, respectively.

[0020] The cam adjustment toothed disc 32 is connected to the output shaft of the film roll driving motor 4 through the fixed axis gear train 10. The adjustment cam mechanism 3 also includes a knob 33 and a rotating shaft 34. The film roll is also fixed with an upper fixed plate 11 and a lower fixed plate 12 arranged in parallel. The adjustment cam mechanism 3 is arranged between the upper fixed plate 11 and the lower fixed plate 12. The knob 33 and the cam adjustment toothed disc 32 are respectively fixed to the two ends of the rotating cam 31. The cam adjustment toothed disc 32 and the rotating cam 31 are rotatably arranged at The cam 31 is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs,

[0021] When it is necessary to start the film roll, the upper computer 7 sends a control signal to the processor 5 through the wireless transmission module 6, and the processor 5 starts the film roll drive motor 4 to drive the film roll shaft to perform film winding or film release operations. At the same time, the timing module 8 starts timing. When the film winding reaches the limit position within the set time, the two raised contours 311 of one of the rotating cams 31 respectively trigger the state detection switch and the motor power-off switch in the upper detection component 1. The motor power-off switch cuts off the power supply of the film roll drive motor 4 to stop it from working. The state detection switch feeds back a signal to the processor 5 through the state detection circuit, and the processor 5 uploads the signal to the wireless transmission module 6. Upper computer 7; when the film release reaches the limit position within the set time, the two raised contours 311 of the other rotating cam 31 respectively trigger the status detection switch and the motor power-off switch in the lower detection component 2, and the remaining steps are the same as the above steps; if the film collection or release does not reach the limit position within the set time, it means that the film roll or related equipment has a fault. At this time, the upper computer 7 cannot receive the detection signal uploaded by the processor 5 within the set time. The upper computer 7 controls the alarm module 9 to sound an alarm to prompt the operator that a fault has occurred. At the same time, the upper computer 7 sends a control signal to the processor 5 to stop the film roll drive motor 4 from working to avoid worsening of the fault.

[0022] Figure 2 and Figure 3 The upper detection component 1 in Figure 4 SW1 and SW3B overlap, SW1 is located on the upper side of SW3B and plays the role of state detection, SW3B plays the role of cutting off the motor current. Figure 2 The lower detection component 2 in Figure 4 SW2 and SW3A overlap, SW2 is located on the upper side of SW3A and plays the role of state detection, and SW3A plays the role of cutting off the motor current. The specific working principle is as follows:

[0023] As above Figure 4 As shown, Figure 4The numbers in the figure represent pins, not the reference numbers of components. HF2315F represents the motor driver chip (processor 5), M represents the DC motor (film winder drive motor 4), UOT1 represents the positive pole, and UOT2 represents the negative pole. During operation, when the MCU pin OPEN-D0 outputs a high level, pin 1 of the HF2315F motor driver chip receives a high level signal, causing UOT1 to output a positive voltage and UOT2 to output a negative voltage. The current passes through SW3A's 1-2, passes through the DC motor M, and then passes through SW3B's 5-4 to return to UOT2. The motor drives the gear mechanism to rotate, and the MCU timer starts working. When the cam reaches the upper limit, SW3B's 5-4 is disconnected, and diode D6 reverses and cuts off the current, causing the entire circuit state to be open, and the motor is powered off at both ends and stops rotating. At this time, if SW2 is hit and closed by the cam within the preset range of the timer, the light-emitting diode D2 emits a red light, and the OPEN-JC pin of the MCU detects that the level is pulled low, then it is judged that the equipment is working normally. If SW2 is not hit and closed by the cam within the preset range of the timer, the OPEN-JC pin of the MCU does not detect that the level is pulled low, then the MCU will actively report the equipment failure and promptly notify the farmer of the equipment failure, which requires inspection. The logic of motor reverse shutdown is consistent with the above logic, and vice versa.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
