Fig. 2 is the data communication format figure in the present invention between main frame and fire alarm control unit.
Embodiment
As shown in Figure 1, the invention provides the illumination of a kind of intelligent emergent and evacuation indication system, comprise and to be connected with display screen 3 emergency lighting and exit signs control desk 1 that form by main frame 2, the input interface of main frame 2 connects fire alarm control unit 4, and ARCNET/CAN bus can be adopted to connect, fire alarm control unit 4 is connected with the one group of fire detector 51 ~ 5n be distributed in buildings, the output interface of main frame 2 connects the Emergency Lighting Supply 71 ~ 7n being equipped with communication board, each Emergency Lighting Supply connects corresponding emergency lighting respectively and divides power distribution equipment 81 ~ 8n, emergency lighting divides power distribution equipment 81 to connect illuminating lamp 91 ~ 9n, indicating lamp for emergency 11 ~ 1n, same, each emergency lighting divides power distribution equipment to be all connected with one group of illuminating lamp and indicating lamp for emergency, the like, emergency lighting divides power distribution equipment 8n to connect illuminating lamp a1 ~ an, indicating lamp for emergency b1 ~ bn, native system adopts ups power 6 to power.Communication board gathers the status information of illuminating lamp and indicating lamp for emergency, feeds back to main frame, and the Receiving Host order of sending simultaneously, starts illuminating lamp or indicating lamp for emergency.Main frame 2 is built-in with the planimetric map of buildings, and is shown by display screen 3; Main frame addresses fire detector, illuminating lamp and indicating lamp for emergency, and is presented in real time on the planimetric map of display screen in the position of fire detector, illuminating lamp and indicating lamp for emergency and state.
Main frame 2 is patrolled and examined each communication board with 25ms interval, knows the state of illuminating lamp or indicating lamp for emergency in time.Patrol and examine and can use roll-call mode, a plate byte sent out by main frame at every turn, communication board Auto-matching, and communication board controls two loops, if the light fixture alarm free information on loop, then Returning plate byte terminates; If the light fixture on loop has fault alarm information, the high-order set of the plate byte then returned, main frame enters waiting status, now communication board initiatively sends fault alarm information, when main frame verification is correct, feed back correct answer signal, as incorrect in verified, communication board starts retransmission mechanism, resends warning message until complete.
Similar, in order to know the state of fire detector in time, the every 10s of main frame patrols and examines fire alarm control unit, if within 100s, without once patrolling and examining successfully, then reports communication failure; If once patrolled and examined successfully, or fire alarm control unit initiatively transmits alerting signal, then enter normal communication state.Under normal communication state, main frame receives the warning message that fire alarm control unit sends, and comprises the fire information such as fire alarm, early warning, supervision, interlock, fault, shielding.If warning message is fire alarm, so main frame uniquely determines the position of fire alarm point on planimetric map according to address code.Now system enters State of alarm, and on planimetric map, the coordinate position of corresponding component can glimmer fire alarm icon, and main frame sends audio alert prompting, and fire alarm occurs in certain position, floor room, building.Data communication format between main frame and fire alarm control unit as shown in Figure 2.
Main frame is built-in with emergency preplan emergency evacuation lines database, after fire detector detects fire information, via fire alarm control unit, fire information is sent to main frame, operating personnel are according to the position of the breaking out of fire that display screen planimetric map shows, call the emergency evacuation lines adapted in emergency preplan emergency evacuation lines database, main frame starts Emergency Lighting Supply according to the emergency evacuation lines selected, light illuminating lamp and the indicating lamp for emergency of relevant position, indicating lamp for emergency has forward direction lamp, backward lamp, left-hand lamp and dextrad lamp.When working out prediction scheme, determine the emergency evacuation lines under emergency rating, can direct setting-out between indicating lamp for emergency, equivalent distance now between two lamps is Effective Numerical, establishment prediction scheme personnel need to add forward direction equivalent distance, backward equivalent distance, left-hand equivalent distance and dextrad equivalent distance, and the indicating status of indicating lamp for emergency under being arranged on emergency rating.Equivalent distance can be determined by situations such as whether fire escape width, jam situation, outlet size, actual range, fire escape are known, and passage is narrower, then equivalent distance is larger; Passage more blocks up, then equivalent distance is larger; Export less, then equivalent distance is larger; Actual range is far away, then equivalent distance is larger; Passage is not known, then equivalent distance is large.The position of exit signs indicator on planimetric map is fixing, and the equivalent distance between them is defaulted as infinity (in during establishment, available-1 represents), according to above-mentioned compilation principles, changes corresponding equivalent distance value by actual conditions.
Establishment can determine the direction indication of each indicating lamp for emergency according to the subregion of fire alarm point, to form best-effort path, this subregion generation fire alarm, then the direction of all indicating lamp for emergencies should deviate from this subregion.In this way, evacuation prediction scheme is carried out in the region of easy breaking out of fire in advance, and be stored in emergency preplan emergency evacuation lines database, when a fire, operator on duty observes fire alarm point, calls the emergency evacuation lines adapted.System can preserve at most 16 kinds of emergency evacuation prediction schemes.
Having of lighting is bright, 2 kinds of states of going out, and exit signs exit light and unidirectional pilot lamp have bright, 2 kinds of states of going out, and two-way pilot lamp then has 2
2=4 kinds of states, four-way pilot lamp has 2
4=16 kinds of states.When sending control command unified by 4 to the control byte of pilot lamp, low 4 bits of byte send out lamp state, and high 4 bits are low 4 bit negates.System by starting corresponding exit signs indicator and exit light instruction emergency evacuation lines when fire alarm, is drawn simultaneously and is evacuated path on planimetric map.
System possesses automatic routing pattern, and main frame is when receiving fire information, and the position according to fire detector fire being detected calculates best emergency evacuation lines automatically, can calculate best emergency evacuation lines according to following steps.
First according to the path between the position of alarm set point fire detector and indicating lamp for emergency, dynamic certainty equivalence distance.
If the coordinate of adjacent two indicating lamp for emergencies 11 and 12 is respectively (x1, y1) and (x2, y2), the coordinate of alarm set point fire detector is (x3, y3), and alarm set point can be multiple, occurs simultaneously or successively occurs.
So the direction vector of this section of emergency evacuation lines is: (a, b)=(x2-x1, y2-y1);
The direction vector of its vertical line section L is: (-b, a);
Between alarm set point to indicating lamp for emergency, the equation L of the vertical line section of line is: (x-x3)/(-b)=(y-y3)/a;
Point on L is exactly x=s* (-b)+x3, and y=a*s+y3, s are the slope of L;
(x, y) is substituted into line segment equation and just can obtain t;
For the projected position of alarm set point fire detector and the intersection point of line segments (t.x, t.y) of two indicating lamp for emergencies
Suppose x2>x1, if t.x>x2 or t.x<x1, can judge that the projected position of alarm set point is positioned at outside the line segment of two indicating lamp for emergencies, then contrary during x2<x1;
In like manner suppose y2>y1, if t.y>y2 or t.y<y1, the projected position of alarm set point is also positioned at outside line segment, then contrary during y2<y1.
The projection of removing alarm set point is positioned at outside line segment, and with the situation of distance outside threshold range (fire alarm point does not affect evacuation path corresponding to this line segment in this case) of closest approach, the distance of line segment between alarm set point to indicating lamp for emergency can be calculated:
nDist=Sqrt((x3-t.x)*(x3-t.x)+(y3-t.y)(y3-t.y))；
According to the engineer's scale of planimetric map, this distance represented with pixel can change into actual range.If this distance (such as 5 meters) within the scope of setting, when then this alarm set point finds fire alarm, indicating lamp for emergency 11 is dynamically arranged as-1 to the equivalent distance of indicating lamp for emergency 12, in like manner indicating lamp for emergency 12 dynamically arranges as-1 to the equivalent distance of indicating lamp for emergency 11, represents that the emergency evacuation lines between this two lamp is obstructed.
Then, calculate the bee-line determination emergency evacuation lines between all indicating lamp for emergencies and building exit,
If matrix D
k(i, j) represents from indicating lamp for emergency li by means of only l1, l2 ..., some node in lk arrives the length of the shortest path of indicating lamp for emergency lj, matrix path
k(i, j) represents the label of the successor node of starting point li in the current shortest path from li to lj.
Matrix D
0(i, j), when i==j, compose initial value 0, other compose initial value-1, when only having path between indicating lamp for emergency, insert effective value according to the assignment principle in forecasting edited.Matrix path
0(i, j) composes initial value j.Then following operation is performed:
Loop1 refreshes D, path to k=1, and 2, ┉, n repeat Loop2 and Loop3
Loop2 refreshed rows is to i=1, and 2, ┉, n repeat Loop3
Loop3 refreshes D
k(i, j), path
k(i, j) to j=1,2, ┉, n
[terminating Loop3 circulation]
[terminating Loop2 circulation]
[terminating Loop1 circulation]
Finishing iteration, obtains D
k, be namely the shortest path value matrix between all directions indicating lamp for emergency point.And all indicating lamp for emergencies are to the shortest path of fire exit in plan view, and the backward cresset of current indicating lamp for emergency can from matrix D
kand path
kin try to achieve.System, according to above result of calculation, draws best emergency evacuation lines, the Emergency Lighting Supply on host-initiated emergency evacuation lines, lights illuminating lamp and the indicating lamp for emergency of relevant position.
System, when fire being detected, directly can call the emergency evacuation lines in emergency preplan emergency evacuation lines database; Also can under automatic routing pattern, relative position according to fire detector and indicating lamp for emergency that fire detected calculates best emergency evacuation lines automatically, then Emergency Lighting Supply is started according to the emergency evacuation lines selected, light illuminating lamp and the indicating lamp for emergency of relevant position, reach indication escaping direction, guide people to avoid cigarette, mist and flame, accomplish to evacuate personnel safely and fast, reduce the object of injures and deaths.
Conveniently user safeguards, can be kept in historical data base by calling the historical information of emergency preplan emergency evacuation lines with the best emergency evacuation lines automatically calculated, and user can query calls historical record, carries out trace analysis management.
Emergency lighting and exit signs control desk are monitored in real time to ups power 6 state.System power supply is divided into main electricity work, standby electricity work two kinds of duties, when system looks is to fire alarm, enters emergency rating, cuts off civil power, use standby electricity.When civil power power-off, also use standby electricity.System judges the state such as short circuit, open circuit, charging of ups power simultaneously.For avoiding out present condition to report by mistake, system carries out filtration treatment to monitor data.When power supply is transformed into another kind of state B from a kind of state A, system can not make an immediate response process, and is through the repeatedly screening to information, confirm current be B state errorless after, just can think that power supply is transformed into B state from A condition.Now system interface LED state changes according to actual estimate of situation.Emergency Lighting Supply judges the open circuit of point power distribution equipment, short-circuit condition feeds back to main frame, when a point power distribution equipment is in short-circuit condition, automatically cuts off the power supply of corresponding branch road.
