Electric fork-lift truck supervision system based on LoRa technology

Abstract

The invention discloses an electric fork-lift truck supervision system based on an LoRa technology. The supervision system comprises a plurality of electric fork-lift truck nodes, an LoRa wireless communication device, a data acquisition device, a data real-time display device, an alarm device and a server supervision device; the electric fork-lift truck nodes comprise STM32 microcontrollers whichare responsible for reading, transmitting and receiving data in real time, and comparing the data with a set warning value; the electric fork-lift truck nodes adopt an LoRaWAN network protocol to establish communication with an LoRa gateway of the LoRa wireless communication device. According to the electric fork-lift truck supervision system, information such as load, speed, electric quantity and the like of the collected electric fork-lift truck nodes is displayed in real time on an interactive interface of a cab, which provides great convenience for a driver to obtain current status information of a fork-lift truck; when the set warning value is exceeded, a warning is displayed on a display screen to prevent regulation violating phenomena such as overloading, overspeed, over charge andover discharge and the like; the data of each node is transmitted to a server through a LoRa network to achieve the remote supervision of the fork-lift truck, which is beneficial for management of anentire vehicle team and improvement of work efficiency.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, in particular to an electric forklift supervision system based on LoRa technology. Background technique [0002] Electric forklifts are an important part of the current forklift market due to their environmental protection, energy saving, safety and intelligence, and have obvious advantages over forklifts with internal combustion engines and hybrid power. However, electric forklifts also have some problems. First, the battery life is short. It is mainly caused by improper operation methods, such as sudden acceleration, braking, long-term speeding, excessive charging and discharging, etc. Second, the efficiency of forklift use is low. For example, the unbalanced real-time tasks in different areas of the warehouse will cause some forklifts to be idle, making management and scheduling difficult. Third, lack of data collection function. During the use of electric forklifts, it is nec...
