A beam position monitor(BPM) system is being installed to improve the beam position measurement of the injector at the upgrade project of Hefei Light Source (HLS II). The new BPM system is consists of 19 stripline BPMs and 19 Libera Brilliance Single Pass modules. The parameters and placement of the stripline BPMs were carefully designed. A clock distribution system was built. An EPICS-based control and display system has been developed, including a new record type to calculate the beam position by log-ratio method. The performance of the electronic system is presented based on the laboratory tests as well as real beam test at HLS linac using existing BPMs.
