SMITH remote GPRS wireless control system examples
Water supply, the oil field remote monitoring and state real-time control system

OUTLINE

The water supply, the oil state o remote monitoring and real-time control system is designed and developed by hefei Smith flow meter Co., LTD using  for remote monitoring and controlling user's water. The product has thease feathers: the solar power, or 220 V power supply, GPRS real-time wireless remote transmission, IC card deposits, according to users' balance , automatic control valve , and also can meet the real-time measuring, water supply group accurate control, transparent management and make user demand convenient  ,etc.

System composition and function
System has four parts :solar energy battery, the data acquisition instrument, pipeline equipment and system server

 1, solar battery
Solar battery :make the sun's light energy into electrical energy, direct current deposit in battery output as a signal acquisition instrument of the power supply system
Voltage: 24 V
Current: 2 A
2, pipeline equipment
Pipeline equipment includes flow meters, electric valve , installed in hydraulic supply line, it can monitor the water consumption of users.
3, data acquisition instrument
The power of Data acquisition instrument supply  by solar battery power , the system does not user's power to ensure the independence of the power supply system, data acquisition instrument's main function is :
Ø collection site flowmeter production data
Ø through the GPRS wireless network to the system server
Ø read prepaid phone users after the IC card amount
Ø according to balance control the water valve

4, system server
The background system server is driven by data receiving system and network publishing system, which includes data receiving, data processing, data release, abnormal alarm four modules.
Ø data receiving module: real-time monitoring instrument of receiving the send real-time data;
Ø data processing: according to accept to the source data, and form of summary data;
Ø data release: provide web search function, real-time data, real-time curves and production reports of the query;
Ø abnormal alarm: for now the abnormal situation, provide mobile phone short message alarm function.
