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...
