Electronic information signal processing system

Abstract

The invention discloses an electronic information signal processing system which comprises an input interface, a filterer, a decoder, an operational amplifier, a synchronous separation module, and an encoder. The input interface is connected to the filter and the decoder. The filter is also connected to the decoder, the operational amplifier, and the synchronous separation module. The operational amplifier is also connected to an A / D conversion module through an isolation module. The operational amplifier is also connected to an oscillator and a CPLD module which is connected to the synchronous separation module, the oscillator and the encoder. The encoder is connected to an output interface. According to the system, the on-chip ADC of a DSP is used to realize image collection, a professional video decoding chip is not need, the system has the characteristics of a simple circuit, low cost and easy maintenance and upgrade, more importantly, the system can be adapted to the collection of different standards of electronic signals, when the DSP and the CPLD are used to build a data collection system, the external connection of a professional image collection chip is not needed, a complex hardware design is avoided, and the sufficient processing capacity is provided at the same time.

Description

technical field [0001] The invention relates to an acquisition system, in particular to an electronic information signal processing system. Background technique [0002] The rapid development of the automobile industry provides a broad application market for vehicle electronic products, such as vehicle "infrared surveillance", "reversing radar" and other video surveillance equipment, which brings both convenience and safety to drivers. These monitoring devices are inseparable from video image acquisition, and the key link of video image acquisition is the AD conversion of electronic signals. Traditional electronic information signal processing systems generally use special image acquisition chips, such as the SAA7110 video decoding chip, to automatically complete the image acquisition; the disadvantage is that the circuit is complicated, the cost is high, and it is inconvenient to program and upgrade the software, and the image acquisition The accuracy and speed are also re...
