Radio data and voice compatible, can work in simplex, half duplex, time division duplex TDD, full-duplex mode, receive the same frequency or different frequency transit network, and with remote diagnostics, testing, regulatory functions, or meet the needs of industry dispatch control center and many remote stations for data acquisition and control.
System Architecture
Shenzhen Huaxia Sheng company with a portfolio of SCADA stations set up oil / gas, water, electricity, gas, railways, seismic / weather / environmental, GPS, finance, public security / transport / security, chemical, industrial control automation, data acquisition and control system structure below:
Multipoint wireless data acquisition monitoring system (with remote relay)
Typical examples
1. Force rural power network SCADA / distribution automation / remote metering / electrical load management system
Central dispatch station located in the building power supply bureau, radio RS-232 data port directly connected to SCADA system communication front-end; outside the station for the Office in the substation, switchgear, transformers, radio connection RTU / FTU. System uses polling or CDT work, transmission rate 19200bps. Central station radio can be prepared hot standby switch automatically.
Automatic recovery system, power companies
Shenzhen Sinosun's radio as small, rugged, reliable, working temperature range (-30 ~ +600 c), the outdoor work, making it suitable for distribution automation data communications network, in the distribution network has been widely used. CLP Power Hong Kong's distribution automation project using the 400 sets of WDS 4310 data radio. Power industry in China's Shenzhen Sinosunhas been installed more than 40,000 digital radio sets, stable and reliable. China Dalian Electric Power Bureau, Yancheng, Jiangsu Electric Power, Weifang, Shandong Electric Power Distribution Automation project using Shenzhen Sinosundigital radio.
Wireless Electric Distribution Management
Water / arid water / wastewater treatment control / watershed hydrological forecasting of wireless data communication network
The network for the monitoring and data acquisition system. Central Station is located in the company dispatch center, the main radio station via RS-232 data port is connected with the front-end, and then connect to the corporate LAN servers; outside the stations are located in the water plant, water treatment plants and water supply pipe network of monitoring points, station is directly connected with the collection terminal can monitor and collect water level, pressure, flow, turbidity, chlorine, pumps, frequency and other data for the company's dispatch center and access to relevant analysis and decision-making, improve efficiency, ensure water quality. Some sites, radio stations directly linked to the tower, the outdoor run, to reduce the construction funds. Beijing Shijingshan Yangzhuang water, Changshu, Jiangsu water plant and dozens of water used Shenzhen Sinosun digital radio.
Wireless Water/Wastewater Management
Oil / gas / gas pipeline SCADA system
Shenzhen Sinosun radio for field supervisory control and data acquisition system, the system central station located in the field of data acquisition and control center, stations are located in the outer wells, oil stations, pipeline network monitoring points, etc.; can monitor and capture oil pressure, flow, consistency, temperature, level and other parameters, and control the oil extraction machine start and stop. Xinjiang Tarim Oilfield, Cainan oilfield, Turpan-Hami Oilfield, Shengli Oilfield sea beach SCADA system using Shenzhen Sinosun nearly 1,000 digital radio. The system has been running for years, stable and reliable performance. Currently all oil and gas fields in China's Shenzhen Sinosun station to use more than 60,000 units, SCADA system of choice for oilfield equipment.
Oil / gas data collection and monitoring system
Rail / industrial and mining automation
Shenzhen Sinosun radio station with the railway, mining, and other large enterprises to achieve real-time monitoring of the production process, instead of twisted pair cables, set up with easy installation, removal or removed easily and so on.
Automatic train information collection system
City street light monitoring / weather / environmental data in three remote systems
Shenzhen Sinosun station for city street monitoring, meteorology, environmental protection departments of remote data acquisition and control, high-speed, reliable features, instead of DDN lines, saving the cost of funds.
Urban traffic light control system engineering
