HLM8303 data concentrator is a set of measurement, 485 meter reading, carrier / micro-power wireless meter reading and other functions (public variable terminal) in one, is a comprehensive large number of users of actual demand, with reference to domestic and foreign advanced technical standards , Combined with the actual needs of China's power users develop and design a new generation of public measurement monitoring terminal. Terminal using ARM9 / LINUX high-performance hardware and software platform.Terminal modular design of the advanced concepts, according to the different needs of users can be convenient combination of building blocks. Terminal using GPRS / CDMA as the main means of communication and international well-known manufacturers of communication modules to ensure the high stability of wireless communications. Terminal real-time detection, analysis of power grid and multi-function watt-hour meter work, abnormal immediately reported to the initiative, the loss of power users can be reduced to a minimum. Using the current popular carrier module, with more than 1000 carrier table or collector under the power meter data capacity. Applicable to low-voltage users of the meter reading, electricity monitoring, load control, distribution transformer monitoring, and orderly use of electricity and other occasions.
