Main features:
1 for industrial wireless remote data transmission applications developed based on mobile GPRS network communication terminal, mainly for the meteorological, environmental protection, water conservancy, transportation and other sectors of industrial applications.
2 support dual frequency GSM/GPRS, support short message, GPRS communication
3 embedded TCP/IP protocol stack, enter the public Internet through the mobile terminal without a host to network, communication, more easily integrated into your system.
4 support static fixed IP and domain name resolution, support dynamic domain name, any place any access to the public Internet with fixed IP or dynamic domain name computer, authorized, can receive the data sent by the device.
5 can send data to 1~5 static fixed IP or dynamic domain names at the same time
6 to support data transmission channel, GPRS communication as the main data channel, short message as auxiliary backup data channel.
7 supports remote SMS and wake-up call
8 support online settings parameters to facilitate remote maintenance
9 winsis YD telemetry terminal (RTU) with rainfall detection module, GPRS module, GPRS detection and evaporation water level detection module and GPRS integrated more than two kinds of equipment comprehensive detection GPRS module etc.. RTU can also connect sensor devices with switch output, serial communication interface (TTL or 485) output. The detection module can automatically report the data according to the setting timing, the quantitative acquisition, and the timing, and the real-time calling can be achieved by telephone or sms.
10 RTU with the precipitation, water level and other measurement sensors composed of hydrological information observation station, the collected hydrological data through mobile GPRS communication network to achieve information transmission. Its performance conforms to the national radio management regulations and technical standards, as well as National Hydrological Telemetry telemetry equipment related standards requirements.
11 RTU own data recording function, through setting or programming can achieve timing, quantitative record storage. Record data, power loss is not lost. Record data can be read live or remotely.
12 equipment using mobile G net clock or server clock for timing, does not require regular calibration. If the sensing device has a real-time clock (such as JFZ-01 type digital gauge) can also be used, the sensing device clock for timing, and can automatic sensing device clock calibration (need sensing equipment support). RTU uses the timing connection to send data mode, without real-time online, monthly cumulative flow is small, low cost.
13 equipment according to low power design, lithium battery power supply, small solar panels charging, suitable for field without power supply environment.
14 adopting advanced power supply technology, the power supply has wide range of adaptation, stable and reliable equipment, and can be used in indoor or outdoor environment.
15 RTU with a controllable power supply output, can provide a power supply for sensor equipment.
16 optimize EMC design, suitable for harsh electromagnetic environment and high application requirements.
17 aluminum alloy shell, small size, light weight, beautiful and rugged, suitable for embedded applications.
