Abstract

The invention relates to a vehicle-mounted computer in a motor vehicle driving examination system, in particular to a motor vehicle-mounted computer based on an ARM ((Advanced RISC Machine)) RISC (Reduced Instruction Set Computer) core processor, and aims to solve the problems of low starting speed, low stability, high heating value and high cost of a vehicle-mounted computer in an existing motor vehicle driving examination system. The motor vehicle-mounted computer based on the ARM RISC core processor comprises a DC-DC power circuit, an S5PV210 processor core board, an audio encoding-decoding circuit, an Ethernet interface circuit, a GPS (Global Positioning System) interface circuit, an SD (Secure Digital) card interface circuit, an RS232 serial circuit, a clock battery trickle charging-discharging circuit, a liquid crystal screen interface circuit, an FM (Frequency Modulation) receiving-transmitting circuit, an audio power amplifying circuit, a USB (Universal Serial Bus) concentrator, a USB interface circuit and a USB virtual serial circuit. The motor vehicle-mounted computer is suitable for the motor vehicle driving examination system.

Description

technical field [0001] The invention relates to a vehicle-mounted computer in a motor vehicle driving test system, in particular to a vehicle-mounted computer based on an ARM RISC core processor. Background technique [0002] The vehicle-mounted computer in the existing motor vehicle driving test system generally takes the X86 processor as the core and is based on the industrial computer developed by the desktop computer system. Due to the limitation of its own principle, this kind of industrial computer generally has the problems of slow start, poor stability, high heat generation and high cost, which seriously restricts the performance of the motor vehicle driving test system. Based on this, be necessary to invent a kind of brand-new vehicle-mounted computer, to solve the above-mentioned problems that the vehicle-mounted computer in the existing motor vehicle driving test system exists. Contents of the invention [0003] In order to solve the problems of slow startup, p...
