Simultaneously,, can determine identity, number, present position of trapped personnel etc. as early as possible, utilize hand-held detector to compare accurate search again, thereby find trapped personnel fast, improve rescue efficiency greatly in conjunction with real-time management information.
3, based on the software administration platform of BS structure
The development of this system mainly is based upon on the Java environment, and the framework of this product is clear, helps the autgmentability of this product, and has strengthened product quality.This Products Development framework is divided into the 3-tier architecture of standard: data collection layer, data analysis layer, interface presentation layer.System architecture between each layer as shown in Figure 2.
(1) data acquisition
Data acquisition divides two kinds of methods:
A kind of is to collect nodal information and running status thereof in the mode of POLLER poll;
The 2nd, by ICP/IP protocol, initiatively go up the preset rules information of sending out by agent side.
(2) data are handled
Data are handled and are divided two kinds:
The one, the data of gathering deposit in the database after handling by JAVABEAN;
The 2nd, by some ready-made instruments the very big information of some data volumes is deposited in the file.
(3) data representation
Corresponding data is handled, and data representation also divides two kinds: the one, and by JSP and some special-purpose instruments video data information on browser.Another kind is that the file of opening storage shows.
4, data acquisition delivery platform
Data acquisition uses the wireless transmitted frequency of 2.4GHz, and bandwidth can arrive 1M, the wireless data tranmission techniques of decipherment distance more than 50M.Each data acquisition device connects into data high-speed delivery platform to last by cable, uses cable to fully take into account the geographical features in mine, on each bar cable run, can connect a plurality of data acquisition devices, has simplified the difficulty of wiring like this.
Wireless data transmits, and finishes that valid data are sent on the data acquisition device by wireless network, is sent to the data high-speed delivery platform by cable run then.
Six, the using method of this system
1, downhole personnel management
Native system is followed the principle of " unified hair fastener, unified equipment, unified management ", carries out " people one card " system by permitting personnel on duty and teams and groups, tag card is considered as " job qualification certificate " or " tunnel admission card ".
1) the data acquisition device is installed by Coal Production unit in places such as tunnel, down-hole, chamber, the scope of operations, and lays communication line.
2) after Coal Production unit's input service personnel relevant information, issue and equipment identification card (tag card requires to carry on waistband or be attached in the miner light cap) to the staff that goes into the well.
3) system database writes down the corresponding personnel's of this tag card essential information, comprises essential informations such as name, age, sex, affiliated teams and groups, affiliated work post, post, my photo, period of validity.
4) staff who enters the tunnel must carry tag card, when the personnel that hold when the place of recognition system is set by system identification, system will read this card number information, by the system transmissions network, data such as the place that the holder is passed through, time is transferred to the ground monitoring center and carries out data management; If the card number of gathering is invalid, do not have card or enter limiting channel, system will report to the police automatically, and the operator on duty of the Surveillance center signal that receives the report for police service is carried out associated safety work management program immediately.
5) production unit can carry out empowerment management to this tag card according to the production schedule.The scope of authority comprises: the tunnel or the scope of operation that this employee can access.For preventing that unrelated person and unauthorized person from entering the tunnel or the scope of operation, system be provided with the prescriptive jurisdiction module of this card access tunnel or the scope of operation and card inefficacy, report lost property to the authorities etc.
6) in a single day security incident takes place in the tunnel, and the basic condition of trapped personnel can be known by Surveillance center in the very first time, be convenient to carrying out of accident salvaging.
Native system can generate the form data of the aspects such as Commitment, Accounting and Management of Unit Supply of work attendance operation automatically, can improve management benefit.
2, emergency help and search and rescue system
When personnel in the pit's something unexpected happened, when subsiding as injured or generation top board, under the conscious situation of trapped personnel oneself, can be by pressing distress call knob and the laser lamp on the tag card, carrying out manual operation calls for help, alarm signal is transferred to aboveground control centre etc. by wireless network and Industrial Ethernet network, thereby obtains rescue fast, for life gains time.
Simultaneously,, can determine identity, number, present position of trapped personnel etc. as early as possible, utilize hand-held detector to compare accurate search again, thereby find trapped personnel fast, improve rescue efficiency greatly in conjunction with real-time management information.
