Vehicular digital instrument system with monitoring, parameter-setting and alarm functions

Abstract

The invention relates to a vehicular digital instrument system with monitoring, parameter-setting and alarm functions. The vehicular digital instrument system is communicated with a vehicle control system according to the CANopen (Control Area Network open) protocol and comprises a microcontroller, a debugging interface, an SPIFlash (Serial Peripheral Interface Flash) storage module, a CAN bus module, a power supply module, a liquid crystal display module, an LED (Light Emitting Diode), a buzzer and / or a button. The instrument system program realizes friendly display by adopting various methods, so that the instrument system provided by the invention has the functions of system monitoring, system parameter setting, fault alarm and the like, and the vehicular digital instrument system is concretely used as a vehicular instrument system of an industrial vehicle such as an electric vehicle.

Description

[0001] technical field [0002] The invention belongs to the field of instruments in the industrial vehicle industry, and in particular relates to a digital instrument system for vehicles with functions of monitoring, parameter setting and alarming. The instrument system is especially suitable for electric vehicles. Background technique [0003] With the continuous rise of international crude oil prices and the deepening of new energy concepts, the application of electric vehicles in the field of industrial vehicles has become more popular. At present, the electric vehicle instruments selected by domestic electric industrial vehicle manufacturers are either domestic products or fully imported products. They all use standard RS232 or RS485 interfaces for communication, and only have English and digital display functions, and can only simply display power and speed. , does not have more advanced fault display, vehicle information display, vehicle setting and parameter modifica...

AI Technical Summary

Problems solved by technology

At present, the electric vehicle instruments selected by domestic electric industrial vehicle manufacturers are either domestic products or fully imported products. They all use standard RS232 or RS485 interfaces for communication, and only have English and digital display functions, and can only simply display power and speed. , does not have more advanced fault display, vehicle information display, vehicle setting and parameter modification functions, so that electric (industrial) vehicles equipped with such instruments do not have customization and easy maintenance when a fault occurs

In addition, the one-to-one correspondence between the instrument and the control system is not universal, which objectively reduces the market competitiveness of this type of vehicle
