Description
Technical field
The present invention relates to the intelligence location and the supervisory control system of a kind of oil field and mining industry facility, the invention still further relates to the method for supervising of using this intelligence location and supervisory control system.
Background technology
Along with world technology and rapid development of economy, people to the various resource informations in production scene obtain and automation, intellectuality are tended in control, have particularly that danger, manpower are inconvenient to touch, the aspects such as device parameter control of enormous amount.For example: people increase day by day to the demand of oil, petroleum resources are again a kind of non-renewable natural resources, how each post of oilfield enterprise employing mechanism of not addendum in principle guarantees that under this kind condition oilfield enterprise's safety, efficient stable yields are the stem reality that oilfield enterprise faces in addition.Recover the oil usually by oil well in the oil field, measuring station, terminal, multi-purpose station, the crude oil exporting system, oil tank, other facility in natural gas tank and oil field is formed, whole oil recovery factory, the ore deposit, stand operating state of various production facilities and products thereof (as water, oil, gas etc.) corresponding data is (as temperature, pressure, flow etc.) just be directly connected to stablizing and safety of field produces, and these significant datas are at present mostly by manual type regular check every day equipment operation situation and measurement, each creation data of statistical correlation, this objective condition must make labor strength increase the weight of, and influenced the real-time of monitoring of tools and creation data, even accuracy, there is careless omission simultaneously, clerical mistake and hidden danger such as play tricks.At present, some oilfield enterprises of China also take some by reaching purpose to oil well part producing data monitoring and statistics such as the mode of the local wired network of RS485 bus form, portable collecting device or in the mode of GSM short message, solved the problems referred to above to a certain extent, but these technology there is bigger limitation.At first, each oil recovery factory, oil field, ore deposit, the equipment amount that need monitor of standing are bigger, and disperse relatively, wired networking mode difficult wiring, and very flexible, the construction cost height, and be difficult to the location in the short time when network failure occurring and fix a breakdown a little; Secondly, each oil recovery factory, oil field, ore deposit, powerful motor, pump machine even transformer station are all arranged usually in standing, the interference that is produced during these equipment works can directly be invaded network and be caused the cable network paralysis, peripheral equipment cisco unity malfunction all when serious; The 3rd, cable network produces to a certain degree obstacle to the maintenance of each equipment of oil field, in case may cause the physical connection of cable network to lose efficacy because of carelessness when the maintenance personal keeps in repair, makes the cable network cisco unity malfunction.As for portable collecting device, it can only solve the collection and the monitoring problem of part producing equipment or data, and because it need manually be installed on the corresponding production equipment when gathering, corresponding data is collected in the portable set, need frequent dismounting, the interface section serious wear of itself and production equipment, the problem that loose contact maybe can't connect often appears, and will gather the creation data that comes needs manual type to be uploaded to the production monitoring analysis system again, still exists the real-time difference of data and portable set problem such as to lose; Adopt the mode of short message also to have the problems referred to above; As the patent No. is ZL02238313.1 " oilfield production equipment wireless monitoring management system ", its short message based on Global Link (GSM) (SMS) or radio block network (GPRS) communication mode are realized only is monitoring to oil well rig, though solved the monitoring problem of some equipment of oil field shaft mouth, but still exist short message to lag behind, lose, communication is obstructed problem such as GPRS goes offline, its communication equipment is with respect to ZigBee module cost height, also need pay information service expense, the poor stability of the real-time of this system, reliability and control for a long time.
Sensor technology is a kind of Automatic Measurement Technique, is widely used in industry detection range automatically; ZigBee (802.15.4 agreement) technology is a kind of short distance two-way wireless communication technology of a new generation, have low cost (unlicensed band, exempt from patent agreement), low-power consumption (power saving), network capacity is big, safe, interference resistance strong, network self-healing power is strong characteristics, the two fusion also is aided with the limitation that corresponding controllers can overcome above networking mode or system, thoroughly realizes intellectuality location, monitoring and the control of oil field information.
Summary of the invention
The purpose of this invention is to provide a kind of intelligence location and supervisory control system and method, the careless defective that all may cause cable network cisco unity malfunction or paralysis when keeping in repair with the wired networking mode difficult wiring of local, very flexible, the construction cost height that overcomes oilfield enterprise's employing at present, the interference that is produced when being difficult to the location when network failure occurring in the short time and fixing a breakdown point, equipment work and maintenance personal based on radio communication and sensor network; Also having overcome portable collecting device often needs the defective of the interface section serious wear that occurred with corresponding production equipment dismounting, has also overcome to monitor communication such as exist short message to lag behind, lose, GPRS the goes offline problem of being obstructed in the mode of GSM short message.
