Oil field GPRS data acquisition system

the working environment of the oil field is poor, and lightning strikes, earthquakes and man-made damage occur from time to time. How to transmit the relevant data of oil well operation to the central control room has always been a problem. Today, when GPRS is quite mature, oil fields can rely on gprs/gsm network to realize automation and accuracy of meter reading. The power consumption control center can monitor the operation state of the power consumption of the oil plant through the electronic display screen, and each control point will timely transmit the power consumption state to the control center in the form of short message, so that it can automatically, efficiently and timely grasp the power consumption of the oil field, automatically generate the power distribution plan, and implement scientific power marketing and management. This device overcomes the disadvantages of low accuracy of manual meter reading, time-consuming and laborious, and the lack of centralized and effective management, and solves the worries of production

China mobile GPRS system can provide wide area wireless IP connection. The construction of oil well data acquisition and transmission system on the GPRS business platform of mobile communication company to realize the wireless data transmission of oil well data of renewable plastic granulator, which is also a major energy consumer in China, has the advantages of making full use of the existing network, shortening the construction cycle and reducing the construction cost, and the equipment installation is convenient and the maintenance is simple. After comparison and analysis, we choose GPRS system of China Mobile as the data communication platform of environmental protection information collection and transmission system

since GPRS communication is a data packet communication network based on IP address, the monitoring center computer needs a fixed IP address or a fixed domain, and fatigue damage is often generated after a long action time and more load cycles. Each data collection point uses GPRS module to access the host through IP address or domain name, so as to carry out data communication

the oil field information collection point automatically collects the oil well information through the oil well controller, and is connected to the GPRS DTU terminal through the RS232 or RS485 interface. The data collected by the oil well controller is processed by the built-in embedded processor of the GPRS DTU terminal and sent to the GPRS wireless network after protocol encapsulation

the server adopts public access to the Internet, such as ADSL dial-up/broadband of special telecommunication line, and applies for public fixed IP address

gprs oil well data monitoring system has the following characteristics:

1. High reliability: compared with SMS short message mode, GPRS DTU adopts connection oriented TCP protocol communication, which avoids the phenomenon of data packet loss and ensures reliable data transmission. The center can transmit data simultaneously with multiple monitoring points without interference. GPRS network has perfect frequency division multiplexing mechanism and strong anti-interference performance, which completely avoids the multi machine frequency band collision phenomenon of traditional data transmission radio

2. Strong real-time performance: GPRS has the characteristics of real-time, small data transmission delay, and supports multi-point simultaneous transmission. Therefore, GPRS monitoring data center can carry out two-way communication between multiple monitoring points quickly and in real time, which well meets the requirements of the system for real-time data acquisition and transmission. At present, the actual data transmission rate of GPRS is about 30kbps, which can fully meet the demand of system data transmission rate (10kbps)

3. Wide monitoring range: GPRS network has achieved nationwide coverage, with unlimited capacity expansion and unlimited access locations, which can meet the access needs of mountains, towns and cross regions. Due to the large number of environmental protection information collection points, which are distributed throughout the province, some environmental protection information collection points are located in remote areas, and the geographical location is scattered. Therefore, GPRS network is the ideal choice

4. Low system construction cost: due to the use of GPRS public platform, there is no need to build a network, just install equipment, and the construction cost is low; It also eliminates network maintenance costs

5. Low operating cost of the system: GPRS public communication is adopted, which is charged at a unified rate nationwide, eliminating the expensive roaming cost of universal material testing machine. GPRS network can be charged according to the actual communication flow of data (1-3 points/1k bytes), and it can also be charged according to the monthly unlimited flow, thus realizing the low-cost communication of the system

6. It can control the instruments and equipment at each monitoring point: through the GPRS data monitoring center, it can realize the remote control of field equipment, such as: remote switch control, remote reset control, remote status query, remote parameter configuration, remote firmware upgrade, etc

7. The transmission capacity and expansion performance of the system are good: the oil well monitoring center should realize real-time connection with each oil well data acquisition point. Due to the large number of oil well data acquisition points, the system is required to meet the needs of sudden data transmission, and GPRS technology can well meet the needs of sudden data transmission; Because the system adopts mature tcp/ip communication architecture and has good expansion performance, a monitoring center can easily support the communication access of our machine with thousands of on-site collection points in your local area

8. GPRS transmission power consumption is small, which is suitable for the field power supply environment: although it has two-way communication with the data center thousands of miles away, GPRS data transmission equipment only needs to communicate with the nearby mobile base station when working. Its overall power consumption is equivalent to that of an ordinary GSM, with an average power consumption of only about 200 MW, which is much smaller than the traditional data transmission radio. Therefore, GPRS transmission mode is very suitable for use in the field where solar power or battery power is used
