The specific embodiment
Referring to accompanying drawing one embodiment is described in detail.
In the prior art, safety system adopts the device of the mechanical systems such as contact switch and relay circuit, and in the present embodiment, safety system is made of with electronics packages such as controllers the safety that has adopted microcomputer.
Safety is a kind of performance-oriented electronic safety system with controller, and its combination is carried out high-performance treatments from the information of a plurality of sensors and safety switch input by software, realizes higher performance by combination various states signal.
Fig. 1 is the integral structure figure of expression one embodiment of the present invention.As shown in Figure 1, lift car 2 is connected by main hoist cable with counterbalanced weight 3, and rope sheave 5 is rotated driving by electrical motor 4, and lift car 2 carries out oscilaltion by rope sheave and moves.When needs stop lift car, be fixed by 6 pairs of rope sheaves 5 of drg (being consisted of by dual system).Drg 6 also is used at elevator the lift car emergent stopping having occured to make when unusual.
Elevator shown in Fig. 1 is the elevator that has adopted electronic safety system, the safety of microcomputer by being built-in with high reliability etc. judges that with controller 1 elevator is in normal condition or is in error state, be judged as when being in error state, when cutting off the main power source of powering to electrical motor, make drg 6 actions, make thus lift car 2 emergent stoppings.
Safety for example is made of the microcomputer of dual system with controller 1, and two state and the computing outputs of microcomputer by checking each other the other side can realize high reliability.Safety can come the processing equipment of the electronics mode of installation process logic to consist of with controller 1 by programming by the arithmetic processing apparatus with microcomputer, CPU and DSP, FPGA (decision circuit) etc.
A kind of as in the sensor that detects the abnormal elevator state is provided with governor gear and coder 21 for detection of car speed and amount of movement (miles of relative movement).Governor gear is made of rotatable governor sheave 20 and speed controller rope 22, and this speed controller rope 22 is supported by governor sheave 20, is fixed on the lift car, and links with lift car.Coder 21 (rotary encoder) is installed on the governor sheave 20, rotates in linkage with lift car, and the pulse that produces along with the rotation of coder 21 is counted, and obtains thus speed and the amount of movement of lift car.
The signal of coder 21 is imported into safety with in the controller 1, counts to calculate speed and the amount of movement of lift car by paired pulses.As the speed of lift car and the detecting device of amount of movement, also can adopt in hoist trunk (for example on the guide rail) vertically (lifting direction) paste tape, read the coded message with magnetic means record, and the detecting device that detects with optical mode (for example bar code).
The detection of the floor reference position of each floor and the floor position information of each floor (for example 1 layer, 2 layers) can be undertaken by check-out console 31A, the 31B, the 31C that are arranged on the car position sensor 30 (reflective photoelectric sensor) on the lift car 2 and be installed on the door of elevator lobby of each floor.Car position sensor 30 be positioned at relative with check-out console to the position time, detect the reflected light of sensor from each check-out console.Length by changing each check-out console at each floor and shape etc. can detect lift car 2 whether on the reference position in the regulation of floor at each floor.In order to detect accurately the reference position, can be arranged to detect according to the stair-stepping variation of sensor signal the edge of check-out console.
Calculate lift car 2 according to detected floor reference position and the amount of movement that calculates and stop required stop reference position (stopping height).With the boundary position of check-out console during as the floor reference position, so that the mode of boundary position and interval, floor reference position predetermined distance is come installation and measuring plate 31A, 31B, 31C.Therefore, after detecting the boundary position of check-out console by car position sensor 30, when the car amount of movement that obtains according to coder 21 has reached specified value, illustrate that lift car (more correctly saying car floor) is sitting on the stop reference position of this floor.
In addition, also be provided with for detection of the car door switch 43 of the open state of car door 42 with for detection of Room door switch 41A, 41B, the 41C of the open state of the Room door 40A of each floor, 40B, 40C.As the sensor that detects passenger's load in the car, be provided with spring loaded load cell 32 and be installed in the beam sensor of whether being clamped by car door for detection of the passenger on the car door or not shown opto-electronic pickup.
After the information of sensor (beam sensor of the coder 21 of governor, car position sensor 30, spring loaded load cell 32 and car door) and switch ( Room door switch 41A, 41B, the 41C of car door switch 43 and each floor) is converted into electric signal and serial communication signal, be input to safety with in the controller 1 by signal wire (SW).
Safety is judged the safe condition of elevator with controller 1 according to sensor information and switching information, occured when cutting off main power source, drg 6 to be moved, thereby make the lift car emergent stopping when unusual being judged as.
Fig. 2 is that expression is as the diagram of block of safety with the UCMP of controller 1.Detect the car accidental movement according to car position (the car miles of relative movement of starting at from stopping the reference position) and speed unusual.
Count to calculate car speed by the number of pulses (corresponding with the miles of relative movement of car) to regulation unit time of coder 21 in car speed calculating part 101.The travel direction of lift car (ascent direction or descent direction) is judged according to the signal of coder 21 by car travel direction judging part 102.
Calculate the stop reference position of elevator lobbies and the judging distance X between the car position (car floor position) what calculate to stop distance between reference position and the car position apart from calculating part 104, Fig. 3 is its instruction diagram.Stop the reference position and be the floor reference position that records with car position sensor 30 at a distance of the position of predetermined distance.Car position is obtained according to the car amount of movement of starting at by the time point of floor reference position from lift car.
X=| car position-stop reference position |
=|(∑ΔX+XA)-(XB+XA)| (1)
Δ X represents the car amount of movement with respect to each pulse of governor coder 1, XA represents to stop the reference position, XB represents the distance (specified value) between floor reference position and the stop reference position, ∑ Δ X represents the car amount of movement (along the car travel direction of being judged by car travel direction judging part 102, accumulating computing behind definite "+" symbol or "-" symbol) of starting at by the time point of floor reference position from lift car.
Whether the judging part 105 that opens the door is in open mode (can be arranged to also only judge whether car door is in open mode) according to the Room door switch 41A of car door switch 43 and each floor, the output signal detection car door of 41B, 41C or the Room door of each floor.
Detecting when being in open mode for car door or Room door, the unusual judging part 106 of car position and car speed according to car speed, stop the judging distance X between reference position and the car position and the threshold value of overrunning (unusual judgment threshold) of the car speed set with respect to judging distance X to judge whether to have occured the car accidental movement unusual.
The threshold value of overrunning is as the stop reference position of data bank and each floor and judging distance X is corresponding is stored in the threshold data storehouse 107.Be judged as in reference threshold data storehouse 107 and the car accidental movement occured when unusual, safety is with controller 1 outputting cutting the cut off the power supply signal of terraced main power source and the signal (normally cutting off the signal of the power supply of winch drg) that the winch drg is moved.
Fig. 4 is the diagram of circuit of the action of the electronic UCMP of expression.
Whether the Room door of judging car door and each floor is in open state (F01).When elevator door is not in open state, be judged as that the car accidental movement does not occur is unusual, and end process.
When elevator door is in open state, detect the speed (F02) of lift car.
Calculate current car position and car stop between the stop reference position of layer (perhaps nearest floor) judging distance X (the car miles of relative movement of starting at from the reference position) (F03).
With reference to being stored in unusual judgment threshold (F04) in the threshold data storehouse 107, and compare (F05).
When car speed has exceeded unusual judgment threshold, be judged as lift car and be in car accidental movement error state (F06), and make lift car emergent stopping (F07).
Fig. 5 represents unusual judgment threshold (judgment standard), transverse axis (A01) expression lift car is in the speed of N floor, the position of the longitudinal axis (A02) expression lift car on the lifting direction, the reference position is stopped in dotted line (A05) expression, the unusual judgment threshold of curve A 03 expression.When car speed is positioned at the inboard (stop reference position side) of curve A 03, be judged as normal, when car speed is positioned at the outside of curve A 03, be judged as occured unusual.
Described unusual judgment threshold is set for to stop centered by the reference position, and larger from stopping the judging distance X (to the distance of car position) that starts at the reference position, judgment threshold is less unusually.
For fear of will by the passenger up and down the flexible car speed mistake that causes of hoist cable during elevator be judged as unusual, be set in the operating space curve A 06 of the door open running that also might occur under the normal condition, and unusual judgment threshold A03 is set as the value that operating space curve A 06 adds regulation surplus capacity (surplus capacity that speed detects).
Below the operating space (curve A 06) by the flexible normal door open running that causes of hoist cable is described.
Car when Fig. 6 (A) expression makes winner's hoist cable elongation because a lot of people take advantage of into elevator moves (action of position and speed).Movement locus C01 represents the track of operating point, and the direction of arrow represents the time dependent change direction.At initial point, lift car rests in to be stopped on the reference position (speed is zero).There are being a lot of people to take advantage of into during elevator, the hoist cable elongation, the Speed improving of lift car, lift car descend and stop in a certain position.After this, up-down vibration appears in lift car repeatedly as spring, and static in the final position.
Fig. 6 (B) expression has a lot of people to go down the occasion of elevator, C02 represents movement locus, at initial point, because there being a lot of people to go down elevator, hoist cable shrinks, vibration appears in lift car after rising, and owing to have a lot of people to take advantage of into elevator therebetween, so lift car produces severe jolt at descent direction.
Detect as unusual for fear of being moved by the flexible car that causes of hoist cable, the curve A 06 that preferably will represent the normal region is set as to stop the radial curve centered by the reference position.
Fig. 7 has represented to occur the action when unusual, and dotted line B01 only represents according to the judgment threshold of stopping distance between reference position and the car position and judge the prior art that the car accidental movement is unusual.
In the prior art, when resting against, lift car unusual (fault) occured when stopping on the reference position and when descending while raising speed along movement locus B04, surpassed at car position in the situation of the threshold value that is represented by dotted line B01, detect as having occured unusual, so, lift car continues speed-raising shown in movement locus B06, so that the speed of car becomes large as shown in the figure.Therefore, even make drg action and lift car slowed down detecting unusual time point, still can elongated (representing with existing system in the drawings) to the time that spends till lift car stops and operating range.
In order to prevent from being sandwiched between the ceiling or floor and lift car in entrance hall, needing to arrive lift car stops required distance and is set as threshold value (dotted line B06, B01), consider from security standpoint, preferably dwindle car floor when the passenger flees from elevator lobby from lift car behind the lift car emergent stopping and the difference of height between the floor of entrance hall.
In the present embodiment, owing to judging unusually according to judgment curves A03, so even in the occasion of movement locus B04, also can detect unusually at the intersection point place of B04 and A03.Therefore, compared with prior art, can earlier detect unusually, can shorten to the operating range till stopping, thereby can allow the passenger leave elevator saferly.
Figure 8 illustrates in order to shorten operating range and the shortening time when slowing down, the example of shown in B01, dwindling the judgment threshold B01 of Fig. 7.
In existing mode, might be unusual with the normal door open running action error detection of lift car shown in Figure 5.That is to say, might error detection occur at the regional D02 that exceeds dotted line B01 that is positioned at curve A 06 inboard.
In contrast to this, in the present embodiment, owing to do not have the regional D02 that error detection may occur, so cannot produce error detection.In addition, owing to having exceeded zone (regional D04) detection of the normal region of opening the door for unusually, so it is unusual to form a prompt judgement out with respect to the movement locus D03 of lift car.Its result can improve the safety when having occured that the car accidental movement is unusual, can also avoid meaningless emergent stopping simultaneously, so can improve the quality of elevator operation service.
Fig. 9 shows the example of the setting value of the unusual judgment threshold (judgment standard) of the described embodiment of Fig. 5 having been carried out change.In this example, reference position and the threshold data storehouse 107 corresponding with judging distance X are stopped in change, unusual for the car accidental movement, determine unusual judgment threshold according to making lift car stop at predetermined distance with interior required car speed and the relation of car position.
The necessary condition that makes lift car emergent stopping required speed V and car position X when assigned position (distance) X0 take deceleration/decel β as:
V = { 2 · β · ( X 0 - X ) } - - - ( 2 ) .
In the formula, deceleration/decel when β represents to make the lift car emergent stopping (deceleration/decel of winch drg or second brake (hoist cable drg and guide-rail brake etc.)), X represents to stop the distance between reference position and the car position, V represents unusual judgment threshold, and X0 represents the assigned position (distance) that lift car should stop.
Figure 10 shows another example of the setting value of unusual judgment threshold (judgment standard) having been carried out change.In this example, stop the stop reference position of layer with respect to car, be provided with the not surveyed area (zone between two dotted line A07) of near position (distance) not judged.By not surveyed area is set, vibrate so that near the car speed situation that (amplitude is narrow) moment increases substantially at short notice the stop reference position in the transitionality that is caused by elevator about the passenger, also can prevent error detection, thus, unnecessary emergent stopping can be avoided, the operation service of elevator can be improved.
The diagram of block of Figure 11 and UCMP shown in Figure 2 is suitable, shows according to the characteristic of each floor and car speed and car position to judge the example that the car accidental movement is unusual, in this example, with the floor position of car decision threshold data 109 accordingly.Be specifically, floor position test section 108 detects the floor position (1 layer, 2 layers, 3 layers etc.) of car, and judges that according to carried out optimized threshold data 109 according to each floor position the car accidental movement is unusual.
The signal that is input to floor position test section 108 is the signal from car position sensor shown in Figure 1 (symbol 30) output, when adopting opto-electronic pickup as the car position sensor, can identify each floor according to the shape of check-out console, and also can identify floor information with RFID label or bar code etc.
Thus, even the flexible Oscillation Amplitude of the hoist cable of each floor differs from one another, also can decide suitable judgment threshold according to hoist cable flexible, in apartment etc., set for specific floor (such as the many floors of the many floor of the elderly and child etc.) and can more early detect unusual judgment threshold, can more correct and more promptly judge thus.
Figure 12 represents the judgement characteristic of the setting take floor as unit.
Situation when the floor position of Figure 12 (A) expression lift car is positioned at the superiors, because the length of the main hoist cable of suspention lift car is short, so the flexible Oscillation Amplitude that produces of hoist cable is little, the normal region of the flexible door open running that causes of hoist cable (zone that is surrounded by long and short dash line A06) also diminishes.Therefore, the radius of unusual judgment curves (curve A 03) (center is for stopping the reference position) also diminishes.That is to say, with respect to identical car position, the judgment threshold of velocity anomaly diminishes.
Situation when the floor position of Figure 12 (B) expression lift car is positioned at orlop, because the length of the main hoist cable of suspention lift car is long, so the flexible Oscillation Amplitude that produces of hoist cable is large, the normal region of the flexible door open running that causes of hoist cable (zone that is surrounded by long and short dash line A06) also becomes large.Therefore, the radius of unusual judgment curves (curve A 03) (center is for stopping the reference position) also becomes large.That is to say, with respect to identical car position, it is large that the judgment threshold of velocity anomaly becomes.
Owing to changing the unusual judgment standard of car accidental movement according to floor position, so can unusually judge according to the flexible degree of hoist cable at each floor position, can carry out more correct judgement and protection thus.In addition, also can be arranged to replace floor position with the car height position, set judgment standard according to car height position (such as highly being 10m etc.) and the stroke of hoist cable.That is to say, preferably be arranged to the stop layer of lift car more on the lower, the height and position of described lift car is less, then sets unusual judgment threshold larger.
The diagram of block of Figure 13 and UCMP shown in Figure 2 is suitable, show according to the passenger up and down the state of elevator judge the example that the car accidental movement is unusual.In this example, have or not up and down elevator of passenger by 110 detections of passenger's up/down state judging part, determine unusual judgment threshold data 111 according to testing result, and judge unusually according to unusual judgment threshold data 111.
The detection of passenger's up/down state is according to being undertaken by the variable condition of car internal burden sensor 32 detected car internal burdens or the gate light beam signal (this signal can detect the passenger by car door) of car door.The passenger is being arranged up and down during elevator, according to because of about the main hoist cable that causes of elevator stretch to set unusual judgment threshold, can more correctly judge thus.
Figure 14 show according to have or not the passenger up and down elevator set the example of unusual judgment threshold, curve A 03A represents to have the up and down unusual judgment threshold during elevator of passenger, curve A 03B represents the unusual judgment threshold during elevator up and down without the passenger.The passenger is being arranged up and down during elevator, because the main hoist cable that elevator causes about the passenger is flexible large, so set more greatly with the normal region of door open running (zone that is surrounded by long and short dash line A06 of Fig. 5), and set the radius (center is for stopping the reference position) of unusual judgment curves (curve A 03A) more greatly according to the normal region of the door open running that enlarges.There is not the passenger up and down during elevator, because the passenger's main hoist cable that causes of elevator flexible little up and down, so set the radius (center is the stop reference position) of unusual judgment curves (curve A 03B) a little bit smaller.
Thus, no matter have or not up and down elevator of passenger, all can detect effectively the car accidental movement with shorter operating range, can when improving safety, prevent the decline of elevator operating efficiency.In addition, also can be arranged to replace with the patronage of elevator up and down and have or not up and down elevator of passenger, unusually judge according to the patronage of elevator up and down, and, by the end at hoist cable sensor is set and comes the flexible of direct-detection master hoist cable, can more correctly unusually judge.
