英文摘要	Abstract Receiver system is an indispensable signal receiving equipment for radio astronomical observation. By refrigeration, the noise temperature of the receiver is reduced to a great level, and the sensitivity of the receiver is improved. Therefore, the refrigeration link is particularly important. The cryogenic receiver system of radio astronomy usually adopts compressor compressed helium cycle refrigeration mode. When the compressor is in normal operation, the injected helium high pressure is between 280-300 Psi and the low pressure is between 70-100 Psi. The two pressure values will directly affect the refrigeration efficiency of the receiver. Because the compressor and cryogenic receiver system are both on the radio telescope, engineers are unable to check the pressure state at any time during the observation process. Sometimes, because of temporary power failure or pressure reduction, the receiver warms up and so on, which affects the whole receiving system. Combining with the refrigeration system of Nanshan 26-meter antenna, we have established 6 channels of helium pressure acquisition and remote monitoring, which can better ensure the operation of cryogenic receivers.
