Function and Application of RTU / GPRS in Pumping Station Monitoring System
Pump station monitoring system introduction
First, the system function
1, real-time acquisition of water, water and other important parameters, save the scene, and real-time data transfer to the data center.
2, the computer center can check the status of each pumping station at any time.
3, the computer center to save all the historical data pump station, automatic analysis of the formation of curves, automatic report generation
4, the use of GIS electronic map, each pumping station marked on the map, the figures are directly monitored on the map, intuitive.
5, the control box has AC acquisition module, DC acquisition module, communication management module, digital radio, power module; a transformer, relays, contactors and other devices. Powerful measurement and control.
a, you can remotely control the start-stop pump, on-site manual start and stop, start and stop the scene automatically
b, measuring various parameters of the pump motor, including three-phase pressure, three-phase current, power, power factor, frequency, etc., with display and keyboard for local operation
c, to the pump motor to provide undervoltage, overvoltage, lack of phase, overcurrent, underload automatic protection, automatic on-site alarm, remote alarm
d, equipped with pressure, flow, level transmitter can get the site parameters
e, DC acquisition module can access the infrared detector alarm signal can be on-site alarm, remote alarm
f, remote setting of operating parameters, such as alarm limit, pump start-stop time
g, the function can be extended, such as remote control three-way valve
Second, the system equipment features
1, the use of excellent industrial-grade components production, with excellent temperature characteristics, can work in harsh environments.
2, the use of industrial data transmission devices, data acquisition, transmission, control set in a box, the installation is simple and convenient.
3, GPRS communication is good in real time.
4, hardware, software configuration convenient, easy to maintain and expand.
5, with data power-down protection, long-term preservation of set parameters and historical data.
6, with a watchdog function, the test control box work more reliable.
Third, the system composition
1, computer center: server, GPRS data transmitter, the center of the system software
2, pumping station side: remote control box, GPRS data transmitter, all kinds of instruments, sensors and transmitters, infrared detectors.

The Milling Machine was originally a horizontal milling machine created by American E. Whitney in 1818.In order to mill the spiral groove of the twist drill, American J.R. Brown created the first universal milling machine in 1862, which is the prototype of the milling machine for the lifting platform.The portal milling machine appeared around 1884.Semi-automatic milling machines appeared in the 1920s, and the workbench used the stops to perform automatic conversion of [feed-fast" or [fast-feed".After 1950, milling machines developed rapidly in control systems, and the application of digital control greatly improved the automation of milling machines.Especially after the 1970s, the digital control system and automatic tool change system of the microprocessor were applied on the milling machine, which expanded the processing range of the milling machine and improved the machining accuracy and efficiency.As the mechanization process intensified, CNC programming began to be widely used in machine tool operations, which greatly released the labor force.CNC programming milling machines will gradually replace manual operations.The requirements for employees will also be higher and higher, and of course the efficiency will be higher and higher.
