【Abstract】 Presents the architecture and the operational principle of the distributed observation system of multipoint tempreture. The digit-tempreture (D/T) translator was adopted in the distributed thermo-system based on personal computer(PC) and monolithic processor(MP). In the same time, the amplifier circuit and the A/D circuit, which were adopted in the traditional system, were cut out. This introduces a great reformation to the traditional resistence thermo-circuit.更多还原
