Micro intelligent monitoring unit

With the development of 5G communication technology, the construction of 5G micro stations will also be carried out on a large scale. The GRZF-8 intelligent dynamic environmental monitoring unit, as the core of the 5G micro station power and environmental monitoring system, integrates data collection, control, management, and transmission, and can independently complete the monitoring of small monitoring stations. This product is tailor-made in accordance with the technical requirements of the "QZTT2301.4-2018 Base Station Intelligent Dynamic Environmental Monitoring Unit (FSU) Technical Requirements Part 4: Microstation Type" of the Iron Tower Company. The product has passed the product testing of the Iron Tower Company, meets the unified interconnection B interface technical specifications of the Iron Tower Company's dynamic environmental monitoring system, and can be expanded with the needs of the Iron Tower monitoring business. This product supports multiple transmissions such as GPRS, 4G, NB-IOT, etc. It has the advantages of small size, powerful functions, flexible networking, low power consumption, high protection, and easy installation. It can be widely used for monitoring in harsh environments such as communication, transportation, energy, power, environmental protection, agriculture, etc.
