It can simulate measurement parameters required by external telemetry system. Systemchooses PCI9054 to achieve the interface design with PC,by the way of integrated design of hardware circuit and soft-ware protocol,implementing the various DC analog signal between -10 V to 10 V and RS485 digital signal for highreliability and stable transmission. The long-term experiments showed that the analog signal output stable output error±80 mV,asynchronous munication is stable and reliable system data transfer rates up to 40 Mbit/ words:electronic technology;simulation test system;PCI;asynchronous munication;:6210J doi: / - 睿1,2,张会新1,2,翟成瑞1,2(1. 中北大学电子测试技术重点实验室,太原 030051;2. 中北大
