Abstract
The invention discloses a composite-type intelligent instrument used for an electromobile. A single chip microcomputer used for central control is arranged in the intelligent instrument. The composite-type intelligent instrument is characterized in that a power source input end is accessed to the single chip microcomputer after being connected with a two-stage voltage stabilizing circuit, an electricity quantity sampling circuit and a power failure detection circuit respectively, hourmeter enabling signals are transmitted to the single chip microcomputer through a sampling circuit, and failure sampling signals are transmitted to the single chip microcomputer through a sampling circuit. An input port used for detection failures of external equipment is arranged in the composite-type intelligent instrument, and when the external equipment is in a failure, the composite-type intelligent instrument displays failure codes through an LCD (liquid crystal display) display unit and gives an alarm through LED lamp indicating. By the single chip microcomputer and a peripheral circuit thereof, functions of electricity quantity displaying, a hourmeter and failure displaying are realized, and one instrument realizes the functions of multiple instruments, so that manufacturing cost is effectively lowered, and mounting space is saved.
