The scheme is composed of meter reading management platform, RHU, and terminal communication module. Its functions cover collection and measurement, LTE network data transmission, GPS positioning, remote meter reading, and near-end maintenance, etc., which fully meet the requirements of water supply companies, gas companies and power grid companies for wireless remote meter reading applications.
l Wireless automated data acquisition
l Home and building automation
l Monitoring and control functions in the scenario of industrial Internet of Things
l Wireless alarm and security system
l Iot of sensors (including smoke, air, water, etc.)
l Smart home (such as smart door locks, smart home appliances, etc.)
l Intelligent transportation (such as intelligent parking, automatic charging piles, etc.)
l Smart city (such as smart street lights, logistics monitoring, cold chain monitoring, etc.)
l Ultra-low power consumption: the service life of capacity ER34615+SPC1550 battery pack can reach more than 8 years;
l Easy access: no need to rebuild the network, support mobile Unicom telecom 4G, including LTE-FDD,LTE-TDD,GSM;
l Super capacity: support storage of monthly frozen data for 10 years and daily frozen data for 24 months;
l Two-way communication: data transmission, remote meter reading, query and parameter setting are realized by LTE network;
l Local maintenance: The infrared tool can be used to implement local maintenance, including querying and modifying IP address and APN parameters, and supporting special functions such as firmware upgrade.
l Rich interface: support external photoelectric direct reading meter head, pressure sensor, anti-disassembly switch, etc.;
l IP switching: support the dual IP configuration of the primary server and the standby server. If the primary server fails, it will automatically switch to the standby server.
l GPS positioning: the default galaxy is GPS+ Beidou, accurate positioning, positioning information can be reported to the platform server;
