Description

Remote measurement and control terminal of oil pumping unit

One, technical field:

The utility model relates to a kind of oil pumper remote live observing and controlling (monitoring) terminal that combines digital video technology.

Two, background technology:

At present, the production producing well in each oil field, the whole nation distributes and all relatively disperses, scope is big, and quantity is many, generally all is to adopt the mode of manual patrol collection or adopt various sensors and SCADA system that RTU (RTU) is formed gathers to the production run state of producing well; Safe antitheft situation to producing well generally all adopts artificial patrol or the mode that camera is monitored is installed at the scene.Because the production work data of oil pumper (comprising electric weight, voltage, load, displacement, oil temperature, casing pressure etc.) are smaller, to the requirement of bandwidth and the real-time of data is not very high, so the data transfer mode of existing remote measurement and control terminal of oil pumping unit all is to adopt GSM, GPRS or CDMA communication modes basically in the market; And the live video monitoring image of oil pumper is had relatively high expectations to the requirement of bandwidth and the real-time of data, and practical application is relevant device such as building network and increase network video server voluntarily, and cost is higher.

At present, each oil field is all in the construction of carrying out " digital oil field " and " safety oil field ", because the limitation of observing and controlling (monitoring) equipment, the real-time working state of producing well all is that each becomes system with the safe antitheft situation all the time, well do not combine, exist duplicate construction, constructional difficulties, maintenance workload big, can not satisfy the characteristics of oil field field work.

Three, summary of the invention:

The purpose of this utility model is exactly the defective that exists at prior art, a kind of real-time collection and control function that realizes oil pumper telework data that not only have is provided, also has the remote measurement and control terminal of oil pumping unit of the antitheft real-time monitoring and control of telesecurity of oil pumper simultaneously.

Its technical scheme is: the utility model comprises power interface, sensor terminals, the Data Control chip, video input interface, Digital Video Processing module (DSP), bus driving circuits, CPU control module (ARM), wireless module expansion mouth and data acquisition chip, it is characterized in that: on-the-spot various sensors can directly insert sensor terminals or RS232 interface by wired mode, wireless senser can insert the wireless extensions module by concrete wireless network, the real time data of sensor passes to data acquisition module by bus driving circuits, after carrying out calculation process by the CPU control module then, by RJ45 module or wireless extensions module data message being transferred back to rear end Surveillance center stores, analyze and handle, the control command that rear end control center passes back is explained to carry out by the Data Control chip and is ordered sensor terminals accordingly, carry out corresponding command action, the spot sensor partial information that collects is simultaneously directly preset the Data Control chip of ordering by the CPU control module and is directly carried out, the video monitoring simulating signal at oil pumper scene is linked into video input interface, sound signal is linked into audio input interface, the cradle head control signal is linked into the RS485 interface, audio-video signal and control signal convert digital signal to via Digital Video Processing module (DSP) and transfer back to rear end Surveillance center by network and store and handle, the control command that rear end Surveillance center returns is passed through Digital Video Processing module (DSP) digital-to-analog conversion again and is handled the back by RS485 interface fill order, carry out the corresponding actions of camera lens and The Cloud Terrace, the LED lamp can show the power-up state of the power interface of this terminal, network state and sensor signal transmission state, monitor can be restarted FLASH and SDRAM when terminal self program fleet.

Guarantee at the common moving network of RTU locality or the self-built permanent real-time online of LAN by wireless communication module; Data in real time such as the oil pumper load that data acquisition module collects front end sensors, displacement, electric weight, voltage, oil temperature, casing pressure are transferred to rear end host computer and server, and handle accordingly by software, the Data Control module can be carried out corresponding action to relevant sensor according to the instruction that rear end host computer or server send, the digital video module is that the analog signal conversion at the producing well field camera that will collect is a digital signal, then it is passed back rear end monitoring host computer or server, and store and control.

Be installed in various sensors on the oil pumper by wired or wireless mode by the data collecting module collected corresponding data information, carry out calculation process via the CPU control module, by communication module signal is transmitted back to rear end Surveillance center, the control command that rear end Surveillance center returns reaches the CPU control module via network and carries out calculation process, gives corresponding sensor by Data Control module fill order then.

The analog video signal of field camera and control signal at first insert the digital video module, is digital signal by it with analog signal conversion, this digital signal is passed rear end Surveillance center back by network, the various control commands that rear end Surveillance center returns are converted into 485 control signals via the digital video module, the front end watch-dog carry out corresponding The Cloud Terrace all around, action such as camera lens zoom and focusing.

Effect of the present utility model is: in conjunction with various sensors, can real-time automatic monitoring and the work running status of control oil pumper, at any time control the oil well working condition, avoid the invalid production of oil well, energy savings to greatest extent, and can be by the analysis to electric pump and oil pumper situation, oil well production parameter, raising oil well production efficient; In conjunction with various video monitoring equipments, can 24 hours round-the-clockly in time find abnormal occurrencies such as stolen, punching, fire, industrial accident and malicious sabotage to implementing video monitoring near the producing well, effectively guaranteed oil pumper production safety safeguard work; Solve the artificial problem that the oil pumper running parameter is untimely, precision is low of gathering, realize the remote real-time monitoring of producing well duty and device security, reduce production management personnel's labour intensity, increase work efficiency, also can reduce corresponding production management personnel simultaneously; Effectively remote measurement and control technology and remote control technology are integrated together, complemented each other, greatly reduce the production run cost in oil field.
