[0002] In order to ensure that the vegetables in the greenhouse can obtain a higher yield, it is extremely important to monitor various environmental temperatures in the greenhouse. In the process of plant growth, temperature and humidity are the key factors affecting plant growth. Studies have shown that the temperature and humidity required by plants at different growth stages are different. Reasonable control and regulation of temperature and humidity at various stages of plant growth are very important for increasing the yield and quality of greenhouse vegetables. The greenhouse temperature can usually be monitored by a thermometer or temperature display. The humidity monitoring is still based on the traditional manual humidity monitoring method, which is not only inefficient, but also has large measurement errors. For this reason, we propose a greenhouse temperature and humidity monitoring system based on the Internet of Things, which makes the data collection more accurate and the data viewing more intuitive.

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0027] like Figure 1-2 As shown, a greenhouse temperature and humidity monitoring system based on the Internet of Things includes a monitoring module, a processing module, an Internet of Things transmission module and a VR display module;

[0028] The monitoring module completes the greenhouse temperature and humidity data monitoring by controlling several groups of monitoring devices distributed in three-dimensional nodes, and sends the monitoring data to the data processing module through the Internet of Things module;

[0029] The data processing module processes the monitoring data to form a VR data plane, and transmits the VR data plane to the VR display module through the Internet of Things module;

[0030] The management end views the VR data surface through the VR display module and analyzes the temperature and humidity status of the greenhouse.

[0031] In the present invention, the greenhouse temperature and humidity data monitoring is completed by setting up several groups of monitoring devices with three-dimensional node distribution, and the data is processed by the processing module in a cloud processing manner, and a VR data surface corresponding to the color is generated. Finally, the VR data surface is displayed by the VR display module as a mobile terminal, or a VR data body is constructed and displayed, so that the administrator can intuitively view the various real-time data of the greenhouse, as well as the data changes, so that the collected data is more accurate and the data viewing is more intuitive.

[0032] like Figure 3As shown, the monitoring device includes a mounting plate 1, on which a driving motor 2 and an auxiliary rod 3 are arranged, the output end of the driving motor 2 is connected to a rotating shaft 4, the rotating shaft 4 passes through the auxiliary rod 3 and is connected to the auxiliary rod 3 through a bearing, a winch 5 is arranged on the auxiliary rod 3, a steel wire 6 is wound around the winch 5, and three sensor mounting shells 7 are connected to the steel wire 6; the interior of the sensor mounting shell 7 is hollow, and the side of the sensor mounting shell 7 is provided with a striped through hole, and the interior of the sensor mounting shell 7 is installed with a temperature sensor, a humidity sensor, a photometric sensor, and a carbon dioxide concentration sensor; a plurality of groups of monitoring devices are arranged in an array with equal spacing on the top of the greenhouse, and the driving motor 2 drives the winch 5 to lower the three The sensor mounting shell 7, the lowermost sensor mounting shell 7 is in contact with the ground, the uppermost sensor mounting shell 7 is located at the top of the greenhouse, the middle sensor mounting shell 7 is suspended in the middle, all the sensor mounting shells 7 and the installed sensors serve as a monitoring node, and finally form a three-dimensional node distribution sensor to complete the greenhouse temperature and humidity data monitoring; the monitoring device also includes a controller 8 installed on the drive motor 2, and a wireless wifi module is arranged inside the controller 8. The controller 8 collects data from the temperature sensor, humidity sensor, photometry sensor and carbon dioxide concentration sensor, and forms monitoring data, and the wifi module sends the monitoring data to the Internet of Things module.

[0033] In the present invention, in actual use, the mounting plate 1 of the monitoring device is hoisted on the top of the greenhouse and distributed in a grid. For example, a monitoring device is set at every 10m, and finally several monitoring devices are distributed on a grid point of 10m×10m. Then the drive motor 2 is started. During daily monitoring, the drive motor 2 drives the winch 5 to lower three sensor mounting shells 7. The lowermost sensor mounting shell 7 is in contact with the ground, the uppermost sensor mounting shell 7 is located on the top of the greenhouse, and the middle sensor mounting shell 7 is suspended in the middle. All sensor mounting shells 7 and the installed sensors are used as a monitoring node. Then, the temperature sensor, humidity sensor, photometry sensor, and carbon dioxide concentration sensor are installed inside the sensor mounting shell 7 to start monitoring environmental data, and the monitoring data is sent to the processing module through the Internet of Things module.

[0034] It has to be said that by setting up a monitoring device, the environmental data in the entire space can be monitored in a three-dimensional and gradient manner, making data monitoring more accurate, and in conjunction with subsequent processing modules and VR display modules for display, the collected data is more accurate and the data viewing is more intuitive.

[0035] It is worth mentioning that when the crops are harvested, the winch 5 is driven by the driving motor 2 to retract the three sensor mounting shells 7, so as to facilitate the collection of the crops.

[0036] The processing module adopts cloud processing mode, and the monitoring module and VR display module communicate data with the processing module through the Internet of Things module.

[0037] In the present invention, the Internet of Things module is mainly used for data communication to realize data transmission and information transfer.

[0038] The processing module obtains and processes the monitoring data obtained by several groups of monitoring devices distributed in three-dimensional nodes. The specific processing process is as follows: first, the data interval is divided, and then a mapping relationship is established between the data interval and the color. Then, the monitoring data of the monitoring device at the same height is read, and the monitoring data plane is constructed by interpolation. Then, the corresponding color value is output according to the mapping relationship, and finally the VR data surface is output; finally, the same method is used to output all temperature VR data surfaces, humidity VR data surfaces, luminosity VR data surfaces and carbon dioxide concentration VR data surfaces at different heights.

[0039] In the specific present invention, taking the temperature data collected by the temperature sensor as an example, the data interval is first divided, that is, the temperature range that can appear in the greenhouse is used as the basic range, such as minus 15° to plus 55° as the basic range, and the red R in RGB is used as the color corresponding to the temperature, minus 15° corresponds to the color value of R=0, and plus 55° corresponds to the color value of R=255. The remaining green G and blue B are all 0, and each temperature in the middle vertically corresponds to the color value of color R in equal amounts;

[0040] Similarly, the humidity data collected by the humidity sensor is processed in the same way, and the blue B in RGB is used as the color corresponding to humidity. The humidity corresponds to the color value of B=0 to B=255 respectively; the other green G and red R are all 0;

[0041] The carbon dioxide concentration data collected by the carbon dioxide concentration sensor is processed in the same way, and the green G in RGB is used as the color corresponding to the carbon dioxide concentration; the carbon dioxide concentration corresponds to the color value of G=0 to G=255 respectively; the other blue B and red R are all 0;

[0042] The light intensity data of the photometric sensor is processed in the same way, and the yellow in RGB is used as the color corresponding to the light intensity. The light intensity corresponds to the color values ​​of R=0, G=0 to R=255, G=255 respectively; at this time, the color values ​​of red R and green G in the color values ​​corresponding to each light intensity are always equal, and the value of blue B is always 0.

[0043] In summary, each sampling point has four data, corresponding to four different colors. The entire temperature data is pulled out separately, and the sampling points at the same height are taken as a plane. The sampling points are then interpolated and converted into color values ​​to finally generate a color plane. The color plane displays the actual temperature value at the sampling point at the same time, and finally forms a temperature VR data surface.

[0044] Similar to the temperature data processing method, the processing module simultaneously generates humidity VR data surface, luminosity VR data surface and carbon dioxide concentration VR data surface, and finally sends them to the VR display module through the Internet of Things module.

[0045] The VR display module uses a mobile terminal to obtain all VR data surfaces generated by the processing module through the Internet of Things module, and according to the monitoring content, it constructs temperature VR data body, humidity VR data body, luminosity VR data body and carbon dioxide concentration VR data body, and displays them in real time.

[0046] Specifically, the VR display module has multiple display modes, which can view the temperature data, humidity data, luminosity data and carbon dioxide concentration data of each sampling point separately; or view the various monitoring data in a longitudinal plane, or view the VR data surface generated in the transverse plane, or put the three data surfaces together to obtain a VR data body, or use time as the change axis to view the data changes of each VR data surface over a period of time, ultimately making the collected data more accurate and the data viewing more intuitive.

[0047] Four warning lights 9 are installed on each sensor mounting shell 7. Each warning light 9 emits light of a different color. The four warning lights 9 correspond to the temperature sensor, the humidity sensor, the photometric sensor and the carbon dioxide concentration sensor respectively.

[0048] An early warning unit is provided inside the processing module, and a temperature threshold group, a humidity threshold group, an illuminance threshold group and a carbon dioxide concentration threshold group are stored inside the early warning unit. The temperature threshold in the temperature threshold group changes with time, the humidity threshold in the humidity threshold group changes with time, the illuminance threshold in the illuminance threshold group changes with time, and the carbon dioxide concentration threshold in the carbon dioxide concentration threshold group changes with time. The early warning unit calls up the corresponding threshold at the corresponding time and compares it with the monitoring data to determine whether the threshold is exceeded. If the threshold is exceeded, the corresponding early warning light 9 is controlled to emit light, and a warning notification is sent to the VR display module using the mobile terminal at the same time. The VR display module displays the warning notification to the management end.

[0049] In the present invention, by setting up an early warning module, if the temperature and humidity values, light values, carbon dioxide concentration and other values ​​exceed the preset value range, the alarm system will be activated to perform an acoustic and visual dual alarm, that is, the alarm indicator LED light corresponding to each module will light up and the buzzer sound will be emitted at the same time. If the collected data are all within the threshold range, monitoring will continue.

[0050] It should be added that the temperature sensor corresponds to the red warning light 9, the humidity sensor corresponds to the blue warning light 9, the light sensor corresponds to the yellow warning light 9, and the carbon dioxide concentration sensor corresponds to the green warning light 9. The corresponding colors here are the same as the colors corresponding to the VR display module data, which makes it more convenient for administrators to obtain the monitoring results in the greenhouse in a timely manner.

[0051] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
