Problems solved by technology

Although smart greenhouses have high economic benefits, it is relatively difficult to popularize them at present, mainly due to the following factors: 1. The cost of smart greenhouses is very high, and it takes nearly 200,000 yuan to complete the construction of one mu of land, which is used for planting Ordinary crops are basically non-profitable, but the cost of planting precious crops, such as flowers and medicinal materials, is also quite high. In addition, planting rare species also requires big data technology. Once they cannot be planted, the loss will be greater
2. At present, there are many sensors that need to be arranged at fixed points in a smart shed, and the high-humidity environment formed in the shed due to heating, water spraying, fertilization and irrigation requires very high sealing requirements for various sensors, and the current market The upper sensor cannot completely solve this problem at present. In addition, if water or other liquids accumulate on the surface of the sensor and are not removed in time to form attachments, inaccurate measurement data will easily cause the control system to issue wrong commands. Once the wrong command causes automatic window opening , automatic water spray, automatic heating, automatic warming, automatic drying, automatic increase of CO 2 Wrong execution of such actions may easily lead to accidental death of plants and poultry, etc., resulting in irreparable losses.
3. A large number of electrical control components and driving equipment need to be arranged in the smart shed, and some smart sheds are only covered with plastic film, and the plastic film is easy to break, resulting in rainwater or moist gas entering the shed and contacting the live components of electrical equipment
It is often necessary to spray water in the greenhouse to form fog. The air is very humid, and it is easy to cause short circuit or electric leakage, which poses hidden dangers to personal safety.

Embodiment 1

[0047] The sensor scanning device of this embodiment is as figure 1 , figure 2 and image 3 As shown, it includes a pair of upper and lower elevating rods 601 arranged at both ends, a stay rope 603 is connected between the two elevating rods, and an integrated sensor 609 is hoisted on the sensor hanger 608, and the sensor hanger 608 can move along the The pull rope 603 reciprocates, and when the sensor hanger 608 reaches above the position where data needs to be collected, the integrated sensor 609 lowers it to the position where data needs to be collected by setting out the wire, and then rises back to the initial position after the collection is completed. Realize the on-demand collection of data at various points in the greenhouse.

[0048] The rotating disks on the equipment can move wires in the same direction through the connection of certain rotating disks through chain transmission according to needs, and can also pull or release wires in positive and negative direc...

Embodiment 2

[0050] This embodiment provides another implementation of the sensor scanning device, such as Figure 4 As shown, it includes a pair of upper and lower elevating rods 601 arranged at both ends, and a self-locking mechanism 602 is provided on the elevating rods for locking after height adjustment. A stay rope 603 and a tensioning mechanism 605 are connected between the two elevating rods. The sensor scanning rod 606 and the sensor hanger 608 can reciprocate along the stay cord 603 under the pulling of the stay wire 607. The sensor scan rod 606 has a stay wire ring 604, and the stay wire 607 is worn to control its swing with the stay wire to drive the sensor at its end. Scanning detection of parameters such as temperature, humidity and light intensity in the greenhouse.

Embodiment 3

[0052] The smart greenhouse implemented in this paper is as follows: Figure 5 and Image 6 As shown, there are small ventilation windows 701, pull curtains 703, and guide wheels 702 on the smart greenhouse 7, and pull wires are used to control the execution actions of each mechanism respectively. The sensor scanning device 6 of Embodiment 1 is arranged inside, and the data collected by the sensors enters the control system. System, after the system automatically analyzes and judges, it gives commands to the cable control system, and pulls the corresponding cable to perform specific actions, such as: window opening, water spraying, heating, cooling, drying, CO2 supplementation, etc.

Abstract

The invention discloses a sensor scanning device and an intelligent greenhouse. The scanning device comprises two vertical rods and a guide rail used for connecting the two vertical rods. A sensor integration component is disposed on the guide rail, and is connected with a stay wire, and the stay wire and the guide rail are used to convey the sensor integration component to a position requiring data acquisition. The intelligent greenhouse comprises the sensor scanning device and a greenhouse control cabinet. The greenhouse control cabinet is used to control the sensor scanning device and the ventilation window, the curtain, and other parts of the greenhouse by the stay wire, and the control cabinet is also capable of controlling the other system functions of the greenhouse at the same time. Sensors adopt a dynamic scanning measuring way, and the number of the sensors in the intelligent greenhouse is saved, and the wiring and the installation of the sensors are simplified, and then the detection precision of the greenhouse sensors is improved, and the service lifetimes of the greenhouse sensors are prolonged. By adopting the stay wire for the control, the safety and the reliability of the greenhouse are improved.

Description

technical field [0001] The invention relates to a control / drive mechanism for an intelligent greenhouse, in particular to a sensor scanning device and an intelligent greenhouse, and belongs to the technical field of agriculture. Background technique [0002] With the popularization and application of Internet of Things big data technology in agriculture, the emergence of smart sheds has changed the traditional agricultural planting or breeding mode of relying on the sky, and provided a new way for farmers to get rid of poverty and become rich. At the same time, with the reform of the rural land collective contract system, The more concentrated use of land has also increased the demand for large-scale smart greenhouses. Although smart greenhouses have high economic benefits, it is relatively difficult to popularize them at present, mainly due to the following factors: 1. The cost of smart greenhouses is very high, and it takes nearly 200,000 yuan to complete the construction ...
