Reservoirs are an important part of the flood control engineering system in the river basin and an important node of the national water network, which plays an irreplaceable and important role in flood control, water supply, power generation and ecology. China is the country with the most reservoir dams in the world, with 9 existing reservoirs80,000, more than 80% of which were built in the 50s and 70s of the last century, and the characteristics of many old dams, sick and dangerous reservoirs, and many earth-rock dams greatly affect the continuous operation of the reservoir.
These reservoirs are related to the safety of people's lives and property, and are potential hidden dangers to flood control safety. In particular, small reservoirs are located in remote areas, with poor transportation and communication, and the risk of heavy rains and floods is increasing, so they need to be gradually repaired and integrated into the digital management system. At present, it is the "first period" of winter water conservancy, and Wutong Bolian provides solutions based on water conservancy telemetry gateways to help improve reservoir monitoring and early warning capabilities.
Solution. Multiple sensors (flowmeter, rain gauge, water level gauge, inclinometer, seepage meter, etc.) in the reservoir dam are connected to the Wutong Bolian water conservancy telemetry gateway to collect data such as flow, rainfall, and water level in real time and upload them to the national department's supervision platform (SL651 protocol or MQTT protocol) in real time to realize 5G 4G cloud communication, so as to realize the telemetry monitoring of multiple distributed sites by the remote monitoring center.
Features: 1. Rich interfaces, plug and play for all kinds of sensors and instruments, equipped with network ports, RS232 serial ports, RS485 serial ports, IO ports, etc., and support flowmeters, water level gauges, rain gauges, water quality monitors, cameras and other equipment access.
2. Flexible configuration of a variety of communication methods, supporting 5G 4G, WIFI, GPRS, Beidou and other communication methods, standardizing the collected data, and realizing intelligent collection, data filtering, alarm calculation, jump trigger, formula calculation, grouping strategy, etc.
3. Active reporting of data collection, such as link maintenance report, telemetry station regular report, telemetry station hourly report, telemetry station plus report, etc., support multi-center communication data sharing, and report to the hydrological supervision platform at all levels of provinces, cities and counties, 4. Receive instructions issued by the platform and realize remote control, such as the central station query telemetry station real-time data, the central query telemetry station time data, and can also obtain the pump gate switch and power information for control.
5. Support dual-WAN switching and breakpoint resumption, multiple software and hardware watchdogs, and realize self-repair of equipment operation failures; It supports sending heartbeat detection packet detection, and automatically connects when the connection is broken.
