The Radio Frequency Interference (RFI) generated by the surrounding environment will significantly reduce the observation efficiency of the large radio telescope. The Tian-Ma Radio Telescope (TMRT) has established a RFI monitoring system to keep watch on its surrounding RFI environment chronically in the L, S, C and X bands. The system consists of antennas, receivers, back-ends and control system. To achieve automatic system operation, we design and implement an automation software based on Tango Controls open source framework. This paper will briefly introduce the TMRT RFI Monitoring System (TRMS), and describe the functional design, architecture design and implementation of the automation software. Finally, With the help of this system, we carry out automatic remote monitoring of the RFI environment around the TMRT in the 1.2 GHz-12GHz frequency band, and then analyze and verify the observation results.
