The LT Series RTU is a dedicated controller product developed by Hollysys for remote intelligent control of oil pumping units in oil and gas extraction. It is widely used in oilfield companies such as Daqing, Liaohe, Xinjiang, Tuha, and Changqing. The LT Series RTU intelligent measurement and control terminal adopts a domestic ARM processor combined with embedded software developed based on the Linux open-source operating system, achieving 100% independent controllability. It is widely applied in scenarios such as single-well and regional well site production intellectualization. The product is designed in accordance with "GB/T 34039-2017 Technical Specifications for Remote Terminal Units (RTU)" and PetroChina's "Specifications for Construction of Oil and Gas Production Internet of Things System". It features high-performance computing capabilities and abundant data acquisition, communication, and control interfaces, enabling rapid integration of various measurement and control terminal devices and sensing equipment as well as implementation of intelligent applications
