Atm Embedded Dvr Software Design

With the development of computer and multimedia technology and the production of large harddisk, the embedded harddisk monitor appears. The embeded harddisk monitor is accepted by more and more companys for its operation easy, recorded image clear, operation system alone and not affected by virsus. Xiaxin ATM harddisk monitor is an embedded harddisk monitor designed for ATM. The paper introduces constitutors of ATM embedded harddisk monitor. It is composed of Stream Machine's video compressed chip SM2210, Philips's DSP processor TM1300, Winbond's W78E52 (MCU51 series microprocessor) and quad chip NVC1000 etc. The paper discusses the product's realization, advantage and reliability from thecnoledge and ATM requirements. The paper demonstrates the platform from the constitutes of hardware system, software functions and how to realize these functions (move detection, file system etc.). The paper also introduced the characters and applications of PSOS based on TM1300. I designed MCU51 system software module and finished the programmes of keypad control, remote control, quad control and communication protocol with Tm1300. We have fully considered the expandability of platform and the special requirements of monitor system (two MCU51 chips are used in system that is to add PAN/TILT and modem control easily later for example). Considering the security of recorded data, the file system was designed by ourselves. MMI, alarm and quad functions of the product have its own features too.
