The invention relates to a vehicle state and information identification extracting apparatus. The apparatus detects the parking state of vehicles in a detected area and displays the parking state through an indicating lamp, image information is sent to an access bus according to an instruction of a host computer, and a control instruction of the host computer can be received to enable state information to be displayed. The apparatus comprises an MCU, an image sensing assembly, an ultrasonic detection assembly, a logic control module, a communication assembly, an indicating lamp assembly, a power supply module, etc. Ultrasonic reflection is adopted to detect whether vehicles exit in the detected area, a result is displayed by the indicating lamp and also sent as feedback to the host computer through a communication port, and when the host computer orders the apparatus to send image signals to a bus on the basis of task scheduling situations, the MCU enables signals of the image sensing assembly to be accessed to the bus through the logic control module, and the bus is released if a command of the host computer is cancelled. In this way, a parking lot guiding and vehicle tracking comprehensive system can be easily formed. The mode of the apparatus is formed by an ultrasonic mode and an image mode both of which are effective simultaneously, and the bus control is employed, so the comprehensive cost and the reliability are both guaranteed.
