Design of Remote Control System of Flower Greenhouse Spraying Robot——Based on Internet of Things
Aiming at the problems such as low efficiency,uneven spraying and harm to human health caused by floating drugs in the traditional artificial application of flower film greenhouses,this paper designs a hanging spraying robot system which can realize remote mobile phone control.First of all,according to the growth characteristics of flowers and the spa-tial structure of greenhouses,under the premise of not changing the existing structure of greenhouses,the spraying robot is introduced by adding guide rail.In addition,according to the basic requirements of precise spraying of flowers,the me-chanical structure of the spraying robot is modeled and optimized in SolidWorks.Secondly,MCU esp8266 module is taken as the core control unit to control the hardware such as relay,motor,solenoid valve and liquid medicine pump.The on-off time of relay is adjusted by PWM mode,so as to realize the operation of spraying robot according to different traveling speeds.Finally,the WiFi wireless communication module combined with the Internet of Things platform is used to design the remote control APP terminal to realize the start and stop of the spraying robot and environmental data collection and other functions.The system test shows that the success rate of data transmission is about 98％and 93％,and the packet loss rate is about 1.98％and 7％,respectively,in the environment without shelter and with shelter.The spraying robot operates stably at different speeds.The test results can provide some technical reference for the walking stability of the spraying robot in the greenhouse and the automatic application of flowers.
