Description

The elevator training simulators

The present invention relates to elevator, particularly relate to the training simulators of elevator.

In elevator industry, the technical capacity that constantly improves the attendant is very important.Yet a main problem is, in order to instruct on-the-job personnel's training, often needs " using " user's elevator, thus since the reduction of service ability bring inconvenience to the user.

Our some colleague's certain relay system elevator devices of having used logic and software simulation make the corresponding button, the signal lamp of logic and software and the actual floor button of simulation, car passenger operation board and other analog indicator interface of simulation.(this application has required UK Patent Application UK.8808446.2 number preceence) discloses a kind of elevator training device in No. 89303545.1, european patent application, and it provides a kind of microprocessor mode simulator that is contained in the relay system elevator device in the suitcase.This trainer can be taken home by the learner together with the family learning program of employer's appointment.This microprocessor mode simulator provides a kind of chance, makes the learner can import the condition of various floor call, car call, check system and various other analogue relay formula elevator device internal states.Simulator is according to learner's input, produces output signal, requires the learner to explain, so that " problem " of " conciliation " simulation can importing according to the Instruction Selection shifter of training manual by the teacher or by the learner successfully.

The development of this relay system elevator device simulator has related to engineering technology and program part to a certain degree, control relatively easily.On the other hand, if utilize identical approach, when facing the task of the similar simulator of making a microprocessor formula elevator device, it is so important that the requirement of engineering technology and program becomes, and makes expense become very high.Its reason complexity that to be this modern control technology with the prior art of simple relay system system compare has height like this and the working ability of enhancing, thus make the simulation of software formula the investment of a ratio mutually be arranged with the control of reality itself.

A kind of method that addresses this problem is to set up a place full-sized microprocessor formula elevator device in the training place.Perhaps, in order to reduce the expense of life size elevator hoistways, can come the equipment training place with the small-sized elevator hoistways and the small-sized sensor of a simulation, the small-sized car that Miniature Sensor is used for that sensing drives by a small machine and gear case and the motion of counterweight.The elevator hoistways of simulation can be by microprocessor formula electric life controller interface analog signal and a reality, full-sized.Thereby make the learner can under number teacher's guidance, solve the fault that the teacher proposes.But all learners must go to same training place.

Might make a similar simulator, train operation staff on a life size microprocessor formula electric life controller that is contained on the wheel, this simulator can be trained between the place and be moved at each.Certainly, as mentioned above, a large amount of make that to be contained on the wheel for the employed life size simulator in each training place that spreads all over a country be very expensive.Though this full-sized training simulators provide the chance of demonstration for the teacher, be used for the actual software operation instrument of electric life controller demonstration to reality, this instrument is only used by the teacher usually, not all learner generally can get involved, the learner may just see teacher's action, can imagine, concerning some learners, because the speed of giving lessons is too fast, the main points that everyone may not understand the teacher fully and is proposed.Moreover, because the weight and volume of equipment, at this simulator of everywhere site assembly and to transport this simulator will be pretty troublesome.However, such simulator still may be unusual actv., because it can make the teacher operate real button before learner, and the elevator operation that demonstration is actual, and the control action of coming observation post to take place by explanation.

Perhaps, instructors can be used a real microprocessor formula electric life controller, the heart of this controller normally is contained on the printed circuit board, be used for having only how professor uses operation tool under the condition of printed circuit board (PCB), printed circuit board (PCB) is by the alternating-current voltage/AC voltage power supply that has reduced from the voltage on the wall outlet.At this platform, the teacher can a pick up camera aiming with PC plate bonded assembly operation tool on, and show to the full student of class, so that demonstration is to being stored in the various mode of operation of the software access on the printed circuit board (PCB) by a large-screen image telltale.Although normally used various and the input/output signal circuit card real-time interface can not be revealed in a system that assembles, this method remains useful to the access that shows each memory cell.Yet this training method lacks practical function and the sensation of " taking action on one's own " on the life size simulator, but expense is very low.

For on the basis of the above-mentioned first step further, can adopt the power source special of an energy for this printed circuit board (PCB) power supply of some, so that how to use operation tool to several professors learner simultaneously, although this combination still lacks the function of demonstration and final control action, and the explanation before learner shows, but an operation tool is all arranged in each staff, thereby make the learner can obtain the sensation of actual " taking action on one's own ".

The analog training device that the purpose of this invention is to provide a kind of microprocessor formula elevator device.

According to the present invention, utilize a real microprocessor formula electric life controller, its elevator run signal device with input/output device and software, logic or software and logic and simulation is combined, constitute an elevator training device.

The second, can constitute by printed circuit board (PCB) microprocessor and memory device, that be used for the working control device is housed according to microprocessor formula electric life controller of the present invention.

The 3rd, according to microprocessor formula electric life controller of the present invention, for example, one is contained in microprocessor on the printed circuit board (PCB) and simulation software or logical OR software and logic and input/output device and can packs in the chest that can carry.

The 4th, according to microprocessor formula electric life controller of the present invention can be the microprocessor that contains software, software can pass through a special operating tool access in due form, special operating tool is as an accessory equipment, is used for producing the various situations of change (with the form of software) of elevator device and is used for the variety of issue of diagnosing elevator device to occur.In this case, this operation tool can insert controller, thereby makes the learner can learn to use operation tool on simulator.

The 5th, can comprise the device that is used to select simulated failure according to simulator of the present invention, to be provided for training the means of troubleshooting technology.This fault selecting arrangement only can adopt for the teacher and use, and makes the learner invisible or for the form of learner in conjunction with the self-teaching package use.Perhaps adopt above-mentioned two kinds of forms that technology is used simultaneously.The simulation of the software of simulator or logic, elevator control and the signalling apparatus in elevator and road can be designed to and can decipher selected fault, and provide an analog signal to be used for the effect of the selected fault of simulated real system.

At last, can comprise that according to input/output device of the present invention (perhaps " carrying in fact ") reciprocal button of a plurality of reality is used to simulate floor indicating device and a control panel of the floor of the car call button of the operation board in floor call button, a plurality of simulation car, the stop of an indication car, this control panel can comprise various switches and the indicating device of simulating various elevator states, and comprise one can simulant elevator and the telltale of car door position and motion.

By means of combining of the logic of the microprocessor formula electric life controller of reality and simulant elevator hoistway signalling apparatus, and people's one machine interface that constitutes by input/output device, can reduce to the manufacturing work of microprocessor formula elevator device simulator the ratio of manageable control.Further, if microprocessor controller, analog logic and input/output device are packed in the suitcase, and in fact the learner can use this suitcase so that in taking home and according to learner's oneself wish study.Thereby solved time-consuming essentiality on the classroom with other classmates and teacher, and allowed the learner to grasp speed according to the wish of oneself, the teaching material that uses employer to provide is learnt.After the elevator device of this complexity installs, want in a busy building its elevator device of contact and do not hinder level of service the user, normally very difficult.Therefore, the present invention helps avoid on-site training on the spot a lot of otherwise that must carry out, is used to contact and debug current new type microprocessor formula elevator device.

Jack 150 provides a five digit reading to many signal line 152,154,156,158,160 from simulator plate 26, these signal wire (SW)s lump together and constitute a fast or at a slow speed position signal, are used for utilizing the up-and-down movement of a plurality of 5 * 7 dot matrix read out instruments, 162,164,166,168,170 simulant elevator cars at hoistway.An EPROM172 is programmed, and is used for counting at a slow speed or fast on the response signal line 152,154,156,158,160, and the continuous signal line of one seven bit format is provided for a plurality of latch 174,176,178,180.

This shows that output latch always has 34 output lines, and matrix display has the ability of lighting 35 row LED altogether.Therefore, the row of two on LED of delegation on the telltale 162 and the telltale 170 LED is not used, thereby has used eight row LED in each telltale in four " position " telltale 102.

That is to say that referring to Fig. 5 as can be seen, telltale 102 is made of four square frames that separate of LED, more to simulate a simulation hoistway with four entrance halls.Each square frame 182,184,186,188 all distributes eight row LED.Each square frame has five row LED, and one of them controls every row wherein by many signal line 190,192,194,196,198, promptly by the circuit control of Fig. 7 B, is used for the Kai Heguan of simulant elevator hoistway and car door.

Therefore, 32 kinds of possible positions of the five-bit code word representative simulation car that occurs on the signal wire (SW) 152,154,156,158,160 for every kind of possible position, all must have one group eight LED that go continuously to be lighted.This point can be realized by the clock 200 of a free-running operation, it provides for example method of 2KHZ to BCD counting machine 202, BCD counting machine 202 provides two scale notation output to signal wire (SW) 204,206, be used for to the EPROM172 addressing and for the uses of a BCD one decimal scale conv 208, be used for according to one of the binary counting on the signal wire (SW) 204,206 via four latch of energy disperser 210 gatings 174,176,178,180.

Thereby, combine with two signals on the signal wire (SW) 204,206 from the location addressing signal of jack 150, the access of the form of EPROM172 can be used for, during each cycle of free-running operation clock, the positive numeral collection of row continuously of eight among the LED can be lighted with this form.

In this way, eight row LED will be according to the speed of being controlled by the counting that appears on the signal wire (SW) 152,154,156,158,160, gradually motion up and down in the elevator hoistways 102 of simulation together.This count value by the simulator plate with two kinds of slow or fast speed control, as hereinafter in conjunction with as described in Fig. 8.

Now referring to Fig. 7 B, multi-vibrator 220 produces a square wave that is about 0.25HZ, from signal wire (SW) 222 input BCD counting machines 224.The direction of counting is by U output signal on the signal wire (SW) 228 of an EPLD232 generation or the control of the D output signal on the signal wire (SW) 230.EPLD232 receives (DO) instruction and receive (DC) instruction of closing the door, signal wire (SW) 234 and 236 jack 102b from simulator plate 26 236 of opening the door from signal wire (SW) 234.

For example, suppose the DO signal vanishing volt on the signal wire (SW) 234, i.e. DO order effectively.U signal on the line 228 becomes " 1 " thereupon, makes counting machine 224 increments.Output signal from counting machine 224 on the line 240,242,244,246 is imported FPLD232.Inner FPLD logic is deciphered count signal, so that provide a door conditions, for example DOL, DFC, DS and GS to signal wire (SW) 248,250,252,254 respectively.EPLD232 also provides output signal to signal wire (SW) 256,258,260,262,264, opens the door in order to simulation.Close fully in order to simulate the railway carriage or compartment door, can light the adjacent lamp of whole five row, eight row.Open the door in order to simulate, the base stage that can disconnect transistor 266 is extinguished center one row of eight adjacent lines LED, next, for example after 1/4th seconds, the base stage that disconnects transistor 268 and 270 is simultaneously extinguished two row or the multiple row of row LED both sides of extinguishing previously, after 1/4th seconds, disconnect the base stage of transistor 272 and 274 at last, the outermost residue two row LED of " door " are extinguished, thus the simulation that realization is opened the door.Respectively be listed as LED by means of extinguishing at interval, can simulate the action of opening the door well with 1/4th seconds.

Referring to Fig. 8, the means that realize the simulator 26 of Fig. 2 have been described among the figure.One by intel ^The integrated circuit 300 that EPLD (5C090) constitutes provides five count signals to a plug 302 for signal wire (SW) 152,154,156,158,160, and this plug 302 is connected with jack 150 among Fig. 7 A.

After slave controller 12 receives climb command (U) or decline instruction (D), (integrated circuit 300) respectively on the response signal line 316 and 356 from the command signal T and the G of the controller 12 of Fig. 1, at high speed or the count signal on the drive signal line 152,154,156,158 and 160 at a slow speed.On the signal wire (SW) 308 one directly increases counting from the signal of astable multivibrator 304 fast, and by means of in EPLD300 inside with the signal frequency split on 4 pairs of signal wire (SW)s 308 of coefficient, counting is increased at a slow speed.Thereby accurately express the velocity conditions of being scheduled to by a double speed AC driving elevator of simulator concrete manifestation.

For the situation on the telltale 102 has one more fully to describe among Fig. 5 to appearing at, can suppose that all power supplys all are good for use, " elevator " is not to be operated in the independent operation state, and do not break down, car is positioned at the 3rd layer of " entrance hall " 186, car door is closed, and presses the button 56a by the learner and imported a car call of removing ground floor, following job order then occurs.
