Is an oil and
TOP224YN datasheet and gas production field, set the exploration, development, construction operations, logistical production, diversification, social service as one of professional a complete range of state-owned large enterprises. Oil field exploration, drilling, logging, logging and
TOP224YN price and so is the field operations, liquidity, points, scattered, long distance, construction site, the exchange of information between the company and
TOP224YN suppliers and there is no good solution for a long time. Field of information management attaches great importance to the construction field, clear out the future information technology field for a period of specific goals.
With "wells-line monitoring system", managers can stay at home at any time through the system state observed the production of oil wells. Work well during the data transmission time intervals, wells once the failure of an exclamation point will be marked diagram, maintenance personnel can in the shortest possible time, rushed to the scene, timely troubleshooting. Previously, oil extraction test work to each site to test, time and effort did not say, on the working status of each well is difficult to grasp, sometimes a well failure, often many days after the discovery.
Field working conditions, lightning, earthquakes and man-made destruction have occurred, how to run well the data sent to the central control room has been a problem. Previously, oil has microwave, digital radios method to collect data, but the actual use of the process, the result is not ideal, high-cost inputs and frequent maintenance to oil production units overwhelmed. Introduction of the "online monitoring system wells", the by sensors on the rack, managers can keep abreast of all < / TABLE> work pressure wells, oil production when the voltage, the steam temperature and other data to ensure the safe operation of oil wells.
System description
1. In the pipeline, the intervals from the installation of an ultrasonic flow detection sensor.
2. Each an external ultrasonic flow sensor zigbee wireless nodes, to read and transmit the sensor data.
3. Each ultrasonic flow sensors use an external power supply, AC power is not the case in the use of solar cells.
4. Solar cells need to ensure that the work of more than 3 days time.
5. If the sensors detect the distance between the two flow relatively far, then at intervals of 800 meters between the two using a ZigBee relay.
