When unmanned plane starts to spray insecticide, unmanned plane carries out indoor positioning by Bluetooth beacon, can be accurately to every A grid carries out pesticide spraying.
The unmanned plane obtains the brightness of single grid light compensating lamp when flying to single grid according to light sensor Information and colouring information;
The unmanned plane is newly believed with the plant health degree of the single grid of color value acquisition of information according to the brightness of single grid Breath;
The unmanned plane obtains single grid plant pesticide fountain height information according to the plant health degree information of single grid;
The unmanned plane passes through pesticide spraying device to single grid according to the plant pesticide fountain height information of single network Carry out pesticide spraying.
Unmanned plane selects the pesticide spraying amount in single grid by the plant health degree information of single grid, If unmanned plane judges that plant health does not need to spray insecticide, pesticide spraying is not carried out to single grid, it can be to avoid not needing The plant sprayed insecticide is sprayed pesticide and leads to the underproduction, avoids the waste of pesticide
In an embodiment of the present invention, it is calculated using the following equation the LORA air transmission time.
In equipment initialization, the settable key parameter of user includes signal bandwidth (BW), spreading factor (SF), coding Rate (CR), LORA character rate is calculated using following formula:
The transmission time of lead code is calculated with following formula:
Tp=(Np+4.25)LS
Np indicates the preamble length set, and value can be determined by programming.
As known dormancy time Tp, so that it may determine the number for needing to set lead code by formula above.
In addition to lead code, the air transmission time further includes header and payload, and symbol numbers Ng can be by under formula Face formula calculates:
Symbol meaning is as follows in formula:
(1) PL indicates that byte number (range is 1 to 255) (2) SF of payload indicates spreading factor (range is 6 to 12) (3) IH=0 indicates enabled header: when IH=1 indicates that disabling header (4) opens the optimization of low data rate, DE=1: otherwise DE= 0. (5) CR presentation code rate (range is 1 to 4)
The air transmission time T of header and payloaddAre as follows:
Td=Nd×Ls
The data packet air transmission time is are as follows:
Tpacket=Tp+Td
Unmanned plane sends location information to multiple LORA Bluetooth conversion devices and Bluetooth beacon, LORA Bluetooth conversion device and Location information data are sent to presence server by Bluetooth beacon, and presence server passes through LORA network by calculating location information The time of transmission and transmission speed obtain LORA Bluetooth conversion device and Bluetooth beacon location information, and blue by multiple LORA The location information of tooth conversion equipment and Bluetooth beacon positional information calculation unmanned plane.It is existing if unmanned plane position is out of position Field server sounds an alarm.
The beneficial effects of the invention are as follows
Presence server obtains the health status of each grid implants by infrared camera, according to each grid interplantation Object health status carries out pesticide spraying, realizes the indoor fining pesticide spraying of temperature, improves the efficiency of pesticide spraying.It avoids The plant for being not required to spray insecticide is sprayed the loss of the underproduction caused by pesticide, while also saving pesticide.
Nature ecosystem factor is simulated by artificial means in greenhouse, has built good ecological ring for the breeding and growth of crop Border realizes the balanced production of each season agricultural crops.Intensity of illumination, air humidity in greenhouse, carbon dioxide contain The factors such as the moisture of amount, room temperature and soil, play a crucial role the growth of agricultural crops.Intelligent greenhouse It is that real-time monitoring and tune are carried out to the indoor parameters of temperature using computer networking technology using automatic control system as core Section, makes greenhouse environment parameter close to theoretical optimal value, meets plant growth demand.The Greenhouse Monitoring system in China is relatively at present For backwardness, need to bury a large amount of cables in greenhouse and constructed, not only influence crops farming, but also increase investment at This, increases maintenance difficulties.Even if having part greenhouse using the wireless technologys networking such as WiFi, ZigBee, NB, bluetooth or GPRS, The wireless monitor for realizing greenhouse parameter, solves the drawbacks of wire transmission to a certain extent, but still there are transmission rate compared with Slowly, the problems such as channel is unstable.
Therefore, LORA sensor network communication technical application is allow into user in modern intelligent greenhouse monitoring system Dynamically monitor the parameters such as temperature and humidity, intensity of illumination, carbon dioxide content and the soil temperature and humidity in each greenhouse, and according to Parameters variation makes regulation in time.Traditional greenhouse prison is efficiently solved based on LORA technology wisdom greenhouse group remote monitoring system The drawbacks of survey, walks the modern agricultural development road that environmental-friendly, output is efficient, resource-effective to digital wisdom agricultural system is constructed Road is of great significance.
The present invention can monitor the greenhouse group (in spacious situation up to 8KM) within the scope of 2KM, be particularly suitable for large-scale ecological garden, Farm etc., the construction for domain type wisdom agricultural provides support, as long as owner in the case where mobile phone has signal, can pass through hand Remote monitoring and control is realized in machine APP or computer terminal, after value is more than normal range (NR), is able to achieve remote alarms, and can be automatic Control the parameter value of each temperature indoor environment factor;
The present invention, which makes up current Zigbee, can only realize the monitoring problem of single greenhouse or short distance, without wiring, hold Easily deployment installation, engineering construction convenience are good.Solves the drawbacks of traditional wire wiring, short distance, single Greenhouse Measurement, to structure Build digital wisdom agricultural system, walk environmental-friendly, output is efficient, resource-effective modern agricultural development road have important meaning Justice.
