Abstract

The invention discloses an STM32-based fuel cell forklift safety detection and control system, belongs to the technical field of engineering vehicles and electronic control, and has a function of detecting states of a high-pressure hydrogen storage tank, a hydraulic device and a pedal of a fuel cell forklift in real time based on an STM32 single-chip microcomputer. According to the system, messages indicating the fault states of the DC / DC, the fuel cell and the motor from the CAN bus can be received and detected in real time; the 4G communication module can be used for sending a distress signal and the serial number of the forklift in emergency; and the STM32 main control chip is provided with an emergency safety switch and an emergency call-for-help button, and after a driver presses theemergency safety switch, the STM32 main control chip sends an instruction to the DC / DC converter through the CAN bus, so the DC / DC converter disconnects the power output of the fuel cell to the high-voltage bus.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles and electronic control, in particular to an STM32-based fuel cell forklift safety detection and control system. Background technique [0002] With the rapid development of the logistics industry and new energy vehicles, hydrogen fuel cell forklifts have the advantages of environmental protection, high efficiency, renewable fuel, and long driving range, so the number of hydrogen fuel cell forklifts is increasing. With the development of forklift electrification, the detection of forklift safety status is becoming more and more important. [0003] In the forklift trucks currently on the market, there are problems such as the integration level of electrical safety testing is not high enough, the safety testing is not comprehensive enough, and the real-time performance of safety testing is not high. Contents of the invention [0004] In order to solve the above problems, the present in...
