The Near-infrared Sky Brightness Monitor (NIRBM) aims to measure the middle infrared sky background in Antarctica. The NIRBM mainly consists of an InGaAs detector, a chopper, a reflector, a cooler and a black body. The reflector can rotate to scan the sky with a field of view ranging from 0° to 180°. Electromechanical control and weak signal readout functions are accomplished by the same circuit, whose core chip is a STM32F407VG microcontroller. Considering the environment is harsh for humans in Antarctica, a multi-level remote control software system is designed and implemented. A set of EPICS IOCs are developed to control each hardware module independently via serial port communication with the STM32 microcontroller. The tornado web framework and PyEpics are introduced as a combination where PyEpics is used to monitor or change the EPICS Process Variables, functioning as a client for the EPICS framework. Tornado is responsible for the specific operation process of inter-device collaboration, and expose a set of interfaces to users to make calls. Considering the high delay and low bandwidth of the network environment, the tornado back-end is designed as a master-and-agent architecture to improve domestic user experience. The master node is deployed in Antarctic while multiple agent nodes can be deployed domestic. The master and agent nodes communicate with each other through the WebSocket protocol to exchange latest information so that bandwidth is saved. The GUI is implemented in the form of single-page application based on the Vue framework which communicates with tornado through WebSocket and AJAX requests. The web page integrates device control, data curve drawing, alarm display, auto observation and other functions together.

暗能量光谱仪（DESI）是一个正在进行的光谱调查，以前所未有的精度测量暗能量状态方程。我们描述了DESI天空连续监测系统，它跟踪夜空亮度的系统，动态调整光谱曝光时间，以产生更均匀的数据质量，并最大限度地提高观测效率的一部分。DESI的动态曝光时间计算器（ETC）将天空监测器的天空亮度测量值与导航系统的数据相结合，以计算曝光时间，从而在各种观测条件下实现光谱的均匀信噪比（SNR）。DESI的设计包括20个天空光纤，这些光纤被分成两个相同的天空监视器单元，以提供冗余。每个Sky Monitor单元使用SBIG STXL-6303 e CCD相机并支持八位滤光轮。这两个单元都已完成并交付给基特峰国家天文台的梅亚尔望远镜。调试结果表明，天空监测器提供了必要的ETC所需的性能。
