Ultrashort wave relay / front machine

Ultra-short wave relay/front-end is a scene for ultra-short-wave long-distance communication. According to the needs of the construction of automatic water measurement and reporting system and four years of work experience, SiChuang Technology independently designed multi-channel multi-function data acquisition relay transmission equipment SCR582 The field data is transmitted to the central platform, and the front-end data is processed in real time through the telemetry front communication unit SCC592.

The main function

Telemetry relay SCR582: used to decode, correct, encode, and store the data sent by the telemetry terminal, and transmit the data to the designated center through VHF/GSM/GPR communication.

Telemetry pre-communication machine SCC592: Receives data such as rainfall, water level, wind speed, wind direction, flow rate, voltage, moisture, salinity and temperature transmitted by each telemetry station through VHF/GSM/GPRS communication equipment and data acquisition software. Real-time data processing, storage and other functions.

Features

• Relay machine SCR582

• Multi-protocol support: Support more than 10 kinds of VHF protocols, which can parse multiple message data at the same time.

• Intelligent forwarding control: Automatic real-time forwarding, set forwarding, and waiting for calls according to different protocol requirements.

• Channel Snooping: Wait for idle before the channel is busy and then send, reducing the probability of data collision.

• Multi-channel support: It can expand 2 channels and accept 2 sets of VHF data at the same time.

• Highly reliable design: embedded watchdog technology, self-healing failure, to ensure system stability.
