The experimental Cooling Storage Ring (CSRe) of the Heavy Ion Research Facility in Lanzhou (HIRFL) provides high-quality beam for high-precision mass measurement, atomic physics and other experimental studies. Consequently, accurate measurement of beam parameters is the prerequisite for physical experiments. At present, the control system of CSRe has been upgraded to the EPICS architecture. This paper introduces the current status of the beam diagnostics control system based on EPICS which is affiliated with the accelerator control system. Moreover, some of the beam parameters are measured and analyzed by the upgraded beam diagnostics control system. According to the test results with beam at CSRe, the beam position control system can measure the turn-by-turn position of the injected beam. Furthermore, the calculated turn-by-turn position results show that there is a certain degree of oscillation during the injection process, which affects the injection efficiency directly. The beam current measurement system can achieve precise measurement with DCCT by upgrading a high-resolution data acquisition card, in addition, the D event trigger has been integrated into the beam current control system for receiving the trigger and synchronized information from the virtual accelerator. The upgraded control system is running stably and can measure the beam parameters since the upgrade in 2018 and has been integrated into the graphical user interface (GUI) of the accelerator control system.
