Description

Technical Field

[0001] The utility model relates to the technical field of intelligent greenhouses, and in particular to a greenhouse crop growth environment monitoring device based on communication control. Background Art

[0002] The temperature, humidity and concentration of gases such as carbon dioxide in the greenhouse are related to the growth of crops. Among them, the installation and working methods of most existing monitoring devices for greenhouses are:

[0003] (1) Most monitoring devices are concentrated in the center of the greenhouse for hanging monitoring. Due to the arched structure of the greenhouse, the center of the greenhouse is high, and the environmental monitoring device does not affect normal farming. However, the side of the greenhouse is greatly affected by the external environment, so the environmental monitoring results are different from the actual environmental distribution state in the greenhouse;

[0004] (2) The monitoring device is distributed along the arched structure of the greenhouse and is installed vertically in a suspended manner. It can monitor the side of the greenhouse, but it affects the normal farming work of the workers and causes inconvenience in use. Utility Model Content

[0005] The purpose of the utility model is to provide a greenhouse crop growth environment monitoring device based on communication control, so as to solve the technical problems that in the prior art, only the central position of the greenhouse is monitored, resulting in the environmental monitoring result being different from the actual environmental distribution state in the greenhouse, and the suspended monitoring method affects the normal farming of the staff, resulting in inconvenience in use.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A greenhouse crop growth environment monitoring device based on communication control, comprising a plurality of drive line shafts arranged near the top of a supporting frame of the greenhouse, a pull rope end on each of the drive line shafts being fixedly tied to a side position of the supporting frame of the greenhouse, an environment monitoring sensor being installed on the pull rope of the drive line shaft, and the environment monitoring sensor and the drive line shaft are connected to a control system via wireless communication;

[0008] The control system regulates the driving spool to release the pull rope so that the environmental monitoring sensor hangs down to the side of the greenhouse under the action of gravity, so as to measure the growth environment of the crops on the side of the greenhouse.

[0009] As a preferred solution of the utility model, a storage rack is provided near the top of the supporting frame of the greenhouse, the driving bobbin is installed on the storage rack, and an opening is provided on the side surface of the storage rack so that the pull rope on the driving bobbin can be rolled up and unrolled along the opening.

[0010] As a preferred solution of the utility model, the driving spool includes a servo motor and a rope pull reel installed at the output end of the servo motor. The servo motor is wirelessly connected to the control system, and the servo motor rotates forward and reverse under the regulation of the control system to make the rope pull reel reel up and down to adjust the position of the environmental monitoring sensor.

[0011] As a preferred solution of the utility model, when the pull rope reel is wound and unwound, the environmental monitoring sensor moves in a circle with the position where the pull rope end is fixedly tied to the supporting frame of the greenhouse near the side as the center.

[0012] As a preferred solution of the present utility model, the environment monitoring sensor includes a temperature sensor, a humidity sensor and / or a gas concentration sensor.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The environmental monitoring sensor of the utility model can move to the vertical direction when the pull rope is unwound. By adjusting the installation position of the environmental monitoring sensor, the drooping position of the environmental monitoring sensor can be adjusted, thereby realizing the monitoring of the side growth environment of the greenhouse.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a greenhouse crop growth environment monitoring device based on communication control, including a plurality of driving bobbins 1 arranged near the top of a supporting frame of the greenhouse, a pull rope end on each driving bobbins 1 is fixedly tied to a side position of the supporting frame of the greenhouse, an environmental monitoring sensor 2 is installed on the pull rope of the driving bobbins 1, and the environmental monitoring sensor 2 and the driving bobbins 1 are connected to the control system 3 through wireless communication.

[0022] The control system 3 controls the driving spool 1 to release the pull rope, so that the environment monitoring sensor 2 is drooped to the side of the greenhouse under the action of gravity, so as to measure the growth environment of the crops on the side of the greenhouse.

[0023] As an example of this implementation, the environment monitoring sensor 2 includes a temperature sensor, a humidity sensor and / or a gas concentration sensor.

[0024] When the driving spool 1 is unwound, the length of the released pull rope increases, so the environmental monitoring sensor 2 rotates around the pull rope end fixedly tied to the side position of the supporting frame of the greenhouse under the action of its gravity until it is in a vertical state, thereby being able to monitor the environment on the side of the greenhouse.

[0025] After the monitoring is completed, the driving spool 1 is reeled in to form the pull rope into a tight straight line, so that the position of the environment monitoring sensor 2 is raised, thereby not affecting normal farming.

[0026] Therefore, the monitoring device of this embodiment can achieve two functions. First, it is used to detect the side environment of the greenhouse. Due to the arched structure of the greenhouse, the temperature and humidity of the environment in which the crops in the center of the greenhouse are located are relatively stable and balanced, while the crops on the sides of the greenhouse are greatly affected by the environment outside the greenhouse. Therefore, the monitoring device of this embodiment can be lowered to monitor the growth environment of the crops on the side of the greenhouse. At the same time, the monitoring device of this embodiment can be moved upward to prevent affecting farming.

[0027] Furthermore, on the second aspect, since the temperature and humidity of the environment in which the crops are located at the center of the greenhouse are relatively stable and balanced, the monitoring device of this embodiment is located at the center of the greenhouse when it moves up and resets, and the environmental monitoring sensor 2 is started. The growth environment of the crops at the center of the greenhouse is deduced based on the monitoring results of the environmental monitoring sensor 2 at the high center of the greenhouse.

[0028] Based on the above, in order to ensure the unwinding and rewinding of the drive spool 1, the present embodiment proposes the following embodiments:

[0029] A rack 4 is provided near the top of the supporting frame of the greenhouse, and the driving reel 1 is installed on the rack 4 . An opening 5 is provided on the side surface of the rack 4 so that the pull rope on the driving reel 1 can be rolled up and unrolled along the opening 5 .

[0030] The driving spool 1 includes a servo motor 11 and a rope pull reel 12 installed at the output end of the servo motor 11. The servo motor 11 is wirelessly connected to the control system 3, and the servo motor 11 rotates forward and reverse under the control of the control system 3 to make the rope pull reel 12 reel and unreel to adjust the position of the environmental monitoring sensor 2.

[0031] When the pull rope reel 12 is wound and unwound, the environment monitoring sensor 2 moves in a circle with the position where the pull rope end is fixedly tied to the supporting frame of the greenhouse near the side as the center.

[0032] The environmental monitoring sensor 2 of this embodiment can move to the vertical direction when the rope reel 12 is unwound. By adjusting the distance between the environmental monitoring sensor 2 and the rope end, the downward position of the environmental monitoring sensor 2 can be adjusted, thereby realizing the monitoring of the side growth environment of the greenhouse.

[0033] When the growing environment is not being monitored, the pull rope reel 12 is wound up and the pull rope is tightened, so that the environment monitoring sensor 2 is pulled up to a high position, thereby not interfering with normal farming.

[0034] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
