STM32-based remote control forest fire extinguishing vehicle

Abstract

The invention discloses an STM32-based remote control forest fire extinguishing vehicle which comprises an STM32F103 single-chip microcomputer-based fire extinguishing vehicle body. STM32 resources are fully excavated, a serial port and an I2C bus are used for communication between a chip and a sensor, and a main control board is connected with a WIFI module, so that the vehicle can be remotely controlled by multiple terminals including an Android applet, Bluetooth, a mobile phone APP and a PC; by taking a WIFI module as a medium, data of a sensor can be sent to an upper computer, a control instruction can also be received through the upper computer, the movement of the whole vehicle is controlled by STM32F105, and Mecanum wheels are used as driving wheels of the vehicle, so that the vehicle can adapt to various terrains; automatic control over the water spraying device is achieved, whether the distance of sprayed water can extinguish a fire or not can be judged according to whether flames change or not, the first step is to determine holder direction aiming according to the positions of the flames, and the second step is to increase water pressure or change the elevation angle of a water pump holder as long as water mist is not recognized in video information until water mist appears in the video information.

Description

technical field [0001] The invention relates to the field of intelligent control and image recognition technology, in particular to a remote control forest fire truck based on STM32. Background technique [0002] During the annual fire prevention period, due to the dry climate, it is a high-frequency period of fire occurrence. [0003] Especially in the forest area, once a fire catches fire, it needs to invest a lot of manpower and material resources to put out the fire, and sometimes the firefighters even have their lives in danger. [0004] In response to the above problems, the existing device was improved, and a remote control forest fire truck based on STM32 was proposed, mainly involving complex terrain analysis and recognition, mechanical and intelligent control of fire trucks in forest areas, and flame and smoke based on yolov3 deep learning Comprehensive identification. Contents of the invention [0005] The purpose of the present invention is to provide a remot...

Problems solved by technology

[0005] The purpose of the present invention is to provide a remote control forest extinguishing vehicle based on STM32, aiming at the environment of complex landforms such as forest areas, use unmanned intelligent vehicles to replace firefighters to enter the fire scene detection, use cameras to track the fire source, and send back to the camera in real time. The collected video images can automatically identify the fire source from the video image, and the water gun will automatically aim at the fire source to spray water to extinguish the fire according to the image information, so that the optimal purpose can be achieved at the least cost, and the firefighters can Life safety is guaranteed to a certain extent, and because it can adapt to complex terrain, it can also be used well in urban fires. It can control the speed of the fire truck and adjust the angle of the steering gear pan / tilt in real time through the host computer. It can also be used through the camera. Seeing the current situation in front of the fire truck, and being able to transmit the video information back to the host computer for image processing in real time, which not only has stability but also greatly saves costs, and solves the problems in the background technology
