| Devices include receivers, Demodulators that have digital and network interface, is the development direction now. This project focus on how to realize to control SSD027 receiver used now from either net and get digital voice data of SSD027 receiver and packet to send to a host on the either net that has access right can control the receiver's work parameters,.It discus the Embedded technology, CPLD application circuit design technology and implementation method to get SSD027 receiver connect to either net direct in this paper. It is a different way according to using common computer system in other unit.This paper discus Embedded technology base on RCM3200 module to make SSD027 receiver connect to either net. It adds a pretreatment circuit and a network module in the receiver base to get digital voice data and control parameter. The function of pretreatment circuit that use XC9572 type chip is to convert SSD027 receiver serial digital voice data to parallel data, and provide interrupt purse to RMC3200 module. The RCM3200 module has network function, hardware resource of parallel data port. Software that gather digital voice data and control parameter can download to the module via program bus. If use common computer system to realize network function of SSD027, it has poor reliability and more time delay due to computer hardware failure, network virus, low running speed, A/D convert extra. Use embedded system to make SSD027 receiver to connect either net can result in good reliability of data gather and remote control, low time delay, small volume size, low power consumption, low cost. It fits in with the development direction of receiver design. |
