Fig. 2 shows according to an embodiment of the invention the structural representation near early warning system.
As shown in Figure 2, this near early warning system in, can be divided into two parts according to its residing locus, first is arranged under the ore deposit on the plant equipment, on Lian Caiji, comprise that controller 1(is equivalent to the treating apparatus 108 among Fig. 1), display 2(is equivalent to the display unit 112 among Fig. 1), early warning system receiving element 31(is equivalent to the signal receiving device 106 among Fig. 1), remote control reception unit 32, magnetic field antenna 102, warning flashing lamp 7(is equivalent to the alarming apparatus 110 among Fig. 1, and obviously can also be just like other the alarming apparatus such as alarm bell) etc.; And second portion is arranged on staff's the body, can be fixed by the mode such as wearing, comprise that sniffer 104, program monitoring unit 6(are equivalent to the setting device 114 among Fig. 1) etc. (obviously also can alarming apparatus be set with it the staff, better warn).
For first, at first comprise at least one magnetic field antenna 102, by around it, forming magnetic field, so that the sniffer 104 of second portion can be responded to magnetic field within the specific limits.
After sniffer 104 is sensed the magnetic field of magnetic field antenna 102 formation, generate magnetic field induction information, and be sent to early warning system receiving element 31.On the one hand, early warning system receiving element 31 is sent to controller 1 with the magnetic field induction information that receives, and is judged and is controlled by controller 1; On the other hand, early warning system receiving element 31 is sent to display 2 with magnetic field induction information, by the position of 2 couples of sniffer 104(of display corresponding to the staff) with the ore deposit under the relative position of plant equipment show so that the operating personnel of plant equipment check more intuitively under the ore deposit.
In a kind of comparatively simple mode, the information that can only include " detecting magnetic field " in the magnetic field induction information, then controller 1 is after receiving this magnetic field induction information, just can directly control warning flashing lamp 7 alarming apparatuss such as grade and carry out alarm, operating personnel with plant equipment under the prompting ore deposit make a response, and point out the staff who wears sniffer 104 in time to leave current deathtrap.For this executive mode, need in advance the size according to the deathtrap of setting, the emission of magnetic field intensity of magnetic field antenna 102 is arranged, so that can being detected scope and the deathtrap that device 104 senses, magnetic field matches.In addition, when carrying out alarm, can stop mobile or shutdown by plant equipment under the controller 1 direct control ore deposit, thereby avoid colliding the staff.
In the slightly aobvious complicated mode of another kind, can include concrete magnetic field intensity in the magnetic field induction information, because in the situation that identical, the plant equipment distance is nearer under staff's sniffer 104 with it and the ore deposit, obviously the magnetic field intensity of sensing is also just larger, then controller 1 can according to magnetic field intensity judge the staff current with the ore deposit under the reality, concrete distance of plant equipment, whether be in the deathtrap thereby more accurately judge the staff, in order to make corresponding reaction.
In above-mentioned dual mode, a magnetic field antenna 102 all can only be set can be realized, and in the more complicated mode of another kind, a plurality of magnetic field antennas 102 need to be set at the diverse location of plant equipment under the ore deposit, thereby the magnetic field intensity corresponding to each magnetic field antenna 102 of sensing by sniffer 104, determine the distance of staff and each magnetic field antenna 102, and according to this to staff's particular location around the plant equipment under the ore deposit, and can carry out Real Time Monitoring according to walking about of staff.By this accurately location, can directly show at display 2 on the one hand, so that the operating personnel of plant equipment obtain intuitively impression under the ore deposit, and in time make the reactions such as alarm, shutdown; On the other hand can be according to the residing particular location of staff; judge that the instruction possibility that plant equipment need to be carried out under the current ore deposit threatens to the staff; when being in the right front of plant equipment under the ore deposit such as the staff; if present instruction needs under the ore deposit plant equipment to the left front or move at the rear; then can not threaten to the staff; can directly carry out instruction and do not need to shut down; plant equipment moves to the right front under the ore deposit but if present instruction needs; then owing to may the staff be threatened; controller 1 will not allow this instruction to carry out, to guarantee staff's life security.
In addition, for the staff of operation under the ore deposit and the staff that plant equipment under the ore deposit is operated, owing to the latter need to operate plant equipment under the ore deposit, obviously should be more close with plant equipment under the ore deposit, but still have certain deathtrap.Therefore, can delimit for different staff different deathtraps, and by so that sniffer 104 adopts different tranmitting frequencies when sending magnetic field induction information, thereby corresponding staff's identity information is identified.
Below in conjunction with Fig. 3 and Fig. 4, the steps such as position judgment of the staff under above-mentioned each mode are elaborated, wherein, Fig. 3 and Fig. 4 show according to an embodiment of the invention the operating principle schematic diagram near early warning system.
As shown in Figure 3, under the ore deposit plant equipment 30 around be preset with the deathtrap, such as for same staff, a deathtrap can be set, boundary line 20 of corresponding existence, this deathtrap, then for the first situation described in Fig. 2, can be by the emissive porwer of magnetic field antenna 102 be regulated, so that sniffer 104 will be sensed magnetic field near boundary line 20 or when crossing boundary line 20; For the second situation, can determine in advance the default magnetic field intensity corresponding to boundary line 20, and in real time the magnetic field intensity that comprises in the magnetic field induction information be identified, if greater than default magnetic field intensity, then judge to enter the deathtrap; For the third situation, describe below in conjunction with Fig. 4.
If a magnetic field antenna A1 only is set on the plant equipment 30 under the ore deposit, then at most only can be according to the magnetic field intensity in the magnetic field induction information of sniffer 104 transmissions, judge the distance of sniffer 104 and magnetic field antenna A1, be assumed to L1, then sniffer 104 may be present in take A1 as the center of circle, L1 is on the circle of radius.Circle take A1 as the center of circle among Fig. 4 is smaller, if that setting is magnetic field antenna A3, then can find out from figure, and corresponding circle has covered very large scope, so that the position of sniffer 104 may be in 3 directions of plant equipment 30 under the ore deposit.
And when being provided with two magnetic field antennas, such as A1 and A2, then because sniffer 104 is on two circles simultaneously, just can determine on its intersection point that is in two circles, such as B1 or the B2 that may be among the figure, then in very large range improved the certainty of location of personnel this moment.
Further, if be provided with A3, then the circle take A3 as the center of circle intersects at B2, C, D with first the first two circle respectively again, so, obviously can determine the staff should be in the B2 point or near, thereby determined more exactly staff's position.
In addition, because the magnetic field area coverage of magnetic field antenna is limited, the magnetic field antenna of ordering such as the A4 among the figure possibly can't cover the position that B1, B2 are ordered, if but the staff is in the upper right corner among the figure, then be in the magnetic field antenna that A1 orders and also possibly can't cover, therefore, in order to cover near the zone the plant equipment 30 under the ore deposit comprehensively, more magnetic field antenna can be set, to improve accuracy.
In addition, in Fig. 3, except corresponding deathtrap is set by boundary line 20, several zones can also be set more, such as by in more peripheral position boundary line 10 being set, thereby during regional outside the staff is in boundary line 10, to not carry out alarm, during regional before the staff is in boundary line 10 and boundary line 20, carry out preliminary alarm, such as just carrying out alarm, and the operation of plant equipment under the ore deposit 30 is not disturbed, and be in boundary line 20 with interior when regional, then in alarm as the staff, the operation of plant equipment 30 is avoided the staff is threatened under the control ore deposit.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered that environment is abominable under the mine, affected personnel in the pit's the visual field, earshot, had the potential safety hazard of thrusting into.Therefore, the invention provides a kind ofly near early warning system, can the staff near plant equipment under the ore deposit be warned, avoid since under the ore deposit complicated working environment cause personnel to accidentally injure.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
