Abstract

To enhance the accuracy of position detection and reduce the cost of an elevator control device without deteriorating rescue operation functions by providing means for correcting the content of each memory element for the lowest floor to a reference floor according to a value detected when a cage arrives at the reference floor and to a second reference value. Microcomputers 1A, 1B input reference values CO, CR which correspond, respectively, to the lowest floor MF-2 and a reference floor MF, to respective counters 3A, 3B according to preset specification data. When a counted value (x) is judged to be at the level of the reference floor MF, a CPU sets the reference value CR for the reference floor MF to the counter 3A as a count value. Also, the difference (e) between a count value (x) before correction and the reference value CR is calculated and the reference value CR is written on a memory element P(MF). Thereby the count value in a memory buffer (x) is renewed by the reference value CR and the level of each floor number (m) is corrected to the level of the counted value by subtraction of the count difference (e).

Description

Elevator control method and device

When the present invention relates to et out of order in the car that Dang Duotai is set up in parallel other car is docked with it, thereby rescue the elevator control method and the device of running, relate in particular to elevator control method and device that designs simplification, cost reduce.

For example, Fig. 6 is the block diagram that the spy drives the existing elevator control gear of putting down in writing in clear 57-No. 189985 communiques.

Among the figure, 1A and 1B are corresponding to the car A that is arranged side by side and B (not shown) and the control panel of establishing is made of identical member 2A～5A and 2B～5B respectively, for example is arranged in the Machine Room.

6A and 6B are mobile volume detectors, the corresponding pulse of amount of movement of generation and each car A and B, and input control panel 1A and 1B.

2A is the microcomputer of band CPU and memory device, 3A is the counting machine of counting from the pulse of

mobile volume detector

6A, 4A is taken into the count value of counting machine 3A and it is imported the buffer memory of microcomputer 2A, and 5A is taken into from the count value of the counting machine 3B among the control panel 1B and with it to import the buffer of microcomputer 2A.

Counting machine 3A and mobile volume detector 6A constitute position detecting device, produce the detected value (count value) of the relative distance that shows car A and reference position, buffer 5A constitutes input media, is taken into the detected value of the relative distance that is equivalent to adjacent car B and reference position.

In addition, CPU among the microcomputer 2A differentiates the position of car A and B according to each count value, for this reason, it includes floor position memory, be stored in each corresponding detected value in service floor position of measuring in the running with car A with the form of scheming, when stopping,, make the car A that rescues usefulness run to the stop position of car B according to the detected value in the floor position memory and from the detected value of input media at car B et out of order.

As for the member 2B～5B among the control panel 1B, because their identical with control panel 1A, so omit its explanation.

Below, describe with regard to the action of existing elevator control gear shown in Figure 6.

At first, in the time of periodic inspection etc., before car A and B real-world operation, measure running earlier, the corresponding count value of the car position of initial setting and each floor in

microcomputer

2A and 2B.

That is, being a reference value corresponding to the counting machine 3A of the orlop position of each car A and B and the count value of 3B, the corresponding count value of car position of storage and each floor successively in the memory device of microcomputer 2A.

Now hypothesis car B takes place unusually, be parked between two floors and can not move, then car B be informed to unusually that the staff waiting in the intracardiac monitor (not shown).

Like this, it is unusual that the staff judges that car B takes place, and car A is called out to specific benchmark floor, is multiplied by car A, operates the switch of rescuing among the car A, moves to the stop position of car B.The stop position of car B can be learnt by the count value of reference counting machine 3B.

When the count value of counting machine 3A consistent with the count value of counting machine 3B, when car A arrives the stop position of car B, the staff opens the mouth of rescuing that is located at car A and B top, places springboard between car, utilizes springboard that the passenger among the car B is rescued among the car A.

But the running specifications parameter of the elevator that is set up in parallel is not necessarily identical, for example, as shown in Figure 7, the orlop difference of the floor of each elevator running sometimes.

Among Fig. 7,7A～7C is the running route of three lift car A～C that are arranged side by side, the superiors of each running route 7A～7C are located at floor TOP, the orlop of the running route 7A of car A is floor MF-2 (underground two layers), the orlop of the running route 7B of car B is set in floor MF-1 (B1), and the orlop of the running route 7C of car C is located at floor MF (Stall).

8A～8C is arranged on the key horizon detector on the common key horizon of car A～C (for example floor MF), for example constitutes by being fixed on the special-purpose dull and stereotyped of the floor one side optic coupler relative with special-purpose flat board with being fixed on car one side.

Usually, counting

machine

3A and 3B are key horizon with orlop MF-2 and MF-1 among each control panel 1A and the 1B, counting is from the pulse of

mobile volume detector

6A and 6B, the pulse of counting machine 3A counting is equivalent to the initial amount of movement from orlop MF-2, and the pulse of counting machine 3B counting is equivalent to the initial amount of movement from orlop MF-1.

That is counting machine 3B shows the distance of the relative floor MF-1 of car B, and counting machine 3A shows the distance of car A with respect to orlop MF-2.Therefore, be parked on the position identical, be necessary the count value of

revisal counting machine

3A or 3B, make its unanimity with car B in order to make car A.

Fig. 8 is the block scheme that shows control panel 1A and other existing example of 1B, and different car A and the B of key horizon carries out the revisal of each count value Fig. 7 for resembling.In addition, for fear of too diverse and complicated, omitted diagram to structure of block diagram 1C～6C of car C.

Among Fig. 8,9A and 9B are counting machines, the detection signal of response

key horizon detector

8A and 8B, and counting is from the pulse of

mobile volume detector

6A and 6B, and 10A and 10B are buffers, are used to be taken into the count value of counting machine 9A and 9B, input microcomputer 2A and 2B.In this case, import the count value that counting machine 9B and 9A are arranged among each buffer 5A and the 5B.

At first, in the running of initial mensuration, when car A and B by or when stopping at key horizon MF, counting machine 9A among Fig. 8 control panel 1A and the 1B and the count value of 9B are set at a reference value.Thereby the count value of each counting machine 9A and 9B has shown the relative distance of each car A and B when being benchmark with floor MF, and when car A and B were in same position, count value was identical.

In common running, each

counting machine

3A and 3B counting are from the pulse of

mobile volume detector

6A and 6B, by

buffer

4A and 4B input microcomputer 2A and 2B.The count value of each

counting machine

3A and 3B is handled by

microcomputer

2A and 2B, is used as the position detection signal of car A and B.

On the other hand, when car B because of stopping unusually, when car A rescues running, microcomputer 2A is the count value of the counting machine 9A by buffer 10A and the count value of the counting machine 9B by buffer 5A relatively, thereby can discern the correct stop position of car B, operation car A makes each count value unanimity.

As mentioned above, existing elevator control gear and control method are necessary to be provided with key horizon detector 8A～8C, counting machine 9A～9C and buffer 10A～10C such as special-purpose flat board in order to make the detection position unanimity of many cars that are set up in parallel when rescuing running.Thereby, such problem is arranged, it is complicated that device becomes, and the accuracy of detection deterioration can not realize that in addition cost reduces.

The present invention makes for addressing the above problem, purpose is to provide elevator control method and device, does not need unnecessary members such as key horizon detector, counting machine and buffer, and position detection accuracy is improved, simultaneously, do not damaging realization cost reduction under the situation of rescuing the function of motion.

Below, with reference to description of drawings one embodiment of the present of invention.Fig. 1 is the block scheme that shows an embodiment of elevator control gear of the present invention, and 3A～6A and 3B～6B are and the described identical part of preamble.In addition, though not shown among the figure, identical corresponding to the structure of the control panel 1C of car C and 1A and 1B, running route 7A～7C of each car A～C is as shown in Figure 7.

In this case, microcomputer 1A and 1B will be corresponding to a reference value CO and CR enter counter 3A and the 3B of orlop MF-2 and key horizon MF (with reference to Fig. 7) according to predefined specification data.

Fig. 2 is the block diagram of the structure of microcomputer 2A in the displayed map 1,11A is CPU, 12A is the ROM that writes in advance with the specification data of the running of car A service associated etc., 13A is the RAM that includes the floor position memory of the rolling counters forward value of storing each floor, 14A is used for a reference value CO and CR are input to the interface that counting machine 3A uses (below be designated as I/F), 15A and 16A are the I/F that is used to be taken into by the count value of buffer 4A and 5A, and 17A is the bus that connects each structural unit 12A～16A and CPU 11A.

CPU 11A comprises: judge according to the specification data among the ROM 12A whether car A is in the device of service floor orlop MF-2 in measuring running; Judge when car A is in orlop, give in the floor position memory device of setting the 1st a reference value CO corresponding to undermost storage location and count value; In measuring running, judge according to specification data whether car A is in the device of common key horizon MF; Judge and give the device of setting the 2nd a reference value CR corresponding to the storage location and the count value of key horizon in the floor position memory when car A is in key horizon MF; Count value X when arriving key horizon MF according to car A and the count difference value e of the 2nd a reference value CR revise corresponding to the content of orlop to each storage location of key horizon.

Fig. 3 is the instruction diagram that shows corresponding to the storage space of ROM 12A～12C of car A～C, is that the number of floor levels number of benchmark writes among each ROM 12A～12C as memory image with the orlop of each running route 7A～7C.

Promptly, in ROM 12A, orlop is MF-2, therefore, the number of floor levels of key horizon MF when being (0) with orlop is (2), in ROM 12B, orlop is MF-1, therefore, the floor of key horizon MF is (1), in ROM 13C, orlop is MF, so the number of floor levels of key horizon MF is (0).

Fig. 4 be show with the corresponding RAM 13A of car A in the instruction diagram of storage space of floor position memory, with orlop MF-2 to the corresponding count value of each floor of the TOP of the superiors write successively each storage location P (0), P (1) ..., among the P (n).

In this case, (0)～(n) corresponding to the floor number among the ROM 12A, and P (0) is corresponding to P (MF-2), and P (1) is corresponding to P (MF-1), and P (2) is corresponding to P (MF) ..., P (n) is corresponding to P (TOP).

Below, with reference to the diagram of circuit of Fig. 5, the count value initial setting action that elevator control gear of the present invention carried out shown in instruction diagram 1～Fig. 4.

Here, be representative with car A, be that example describes with following situation, that is, when elevator is installed and during scheduled maintenance inspection, elevator is measured running from orlop MF-2 limit rising edge, constitutes count value figure in the floor position memory in RAM 13A.

In addition, suppose in the ROM of microcomputer 2A 12A, write the running specification data relevant in advance with car A, promptly, when being benchmark with orlop MF-2, corresponding to each floor MF-1, MF (key horizon) ..., TOP (the superiors) the count value of counting machine 3A, and corresponding to a reference value CO and the CR of orlop MF-2 and key horizon MF.

Therefore, CPU 11A writes the count value of counting machine 3A with reference to the floor number figure (Fig. 3) among the ROM 12A in RAM 13A, constitute floor position storage map (Fig. 4).

At first, CPU 11A is according to the output signal of mode detector (not shown), judge whether car A is under the mensuration operation mode (step S1), if mensuration operation mode, whether the count value of then judging counting machine 3A is orlop numerical value, that is, whether car A is parked in orlop MF-2 (step S2).

If car A is parked in orlop MF-2, then by bus 17A and I/F14A with a reference value CO enter counter 3A, will be set at the initial count value (step S3) of counting machine 3A corresponding to a reference value CO of orlop MF-2 (0, perhaps predetermined value 100 etc.).

In addition, in RAM 13A, that is in floor position memory, write predefined a reference value CO (step S4) among at first the memory cell P (0), return then.

Then, in order to measure running, car A begins upwards operation, produces pulse from mobile volume detector 6A, and the count value of counting machine 3A increases.

Like this, in step S2, judging that car A is in operation, promptly is not in stopping, current counting machine 3A count value (step S5) behind the setting increment in memory buffer (MB) X.

Then, judge whether count value X is the numerical value (step S6) of key horizon MF, if not the numerical value of key horizon MF, then judge whether into floor number m (m=1 ..., n) numerical value (step S7).

If count value X is the numerical value of m layer, stored count value X (step S8) in storage location P (m) then is with m increment (step S9).

In addition, the value of m be initially set in advance minimum value (in this case, MF-1=1), car A write count value X by last layer MF-1 o'clock of orlop MF-2 in the storage location P (1) corresponding to floor number 1; Increment is to m=2 then.But, in this case, because m=2 is corresponding to MF, so direct increment is to m=3.

On the other hand, judge that at step S6 count value X is that CPU11A sets a reference value CR corresponding to key horizon MF in counting machine 3A, as count value (step S10) under the situation of numerical value of key horizon MF.In addition, calculating preceding count value X of revisal and the count difference value e (step S11) of a reference value CR, is to write a reference value CR (step S12) among the P (2) at storage location PC (MF).

Like this, the count value among the memory buffer (MB) X is rewritten into a reference value CR, and simultaneously, the numerical value of each floor number m is modified into the count value that begins from key horizon MF by deducting count difference value e.

Then, execution in step S13～S16, the storage location P (K) that has write till the correction car A arrival key horizon MF (K=0 ..., MF-1) count value.At this moment, because orlop is MF-2, have only MF-2 and MF-1 so become the floor number K that revises object.

That is floor number K is reset to 0 (=MF-2) (step S13), deducts count difference value e from being stored in corresponding to the count value the storage location P (K) of orlop MF-2, again write store unit P (K) (step S14).

Then, whether judgment variable K reaches key horizon MF (step S15), if do not reach key horizon MF, then with behind the variable K increment (step S16), repeats step S14.

Like this, will be modified to the count value that begins from key horizon MF with respect to the memory variable P (K) of the floor K from orlop MF-2 to floor MF-1.

Afterwards, at step S6, can not judge that count value X is under the situation of numerical value of key horizon MF, judges at step S7 whether count value m is the numerical value of m layer.And then, with count value X increment, when the last floor of each arrival, all in step S8 in storage location P (m) stored count value X successively.

Step S7～S9 carries out repeatedly, after judge m＞n in step S17, floor number m reaches the floor number n of the superiors, measures running program (Fig. 5) and finishes.

Like this, in the floor position memory that the storage map by Fig. 4 constitutes, deposit the count value of expression from the relative distance of key horizon MF in, this key horizon is common to each car A～C.

Car B and C are carried out the said determination running program too, make it, respectively the such storage map of pie graph 4 corresponding to floor number shown in Figure 3.

By this, arbitrary among car A～C to equal all to have possessed with key horizon MF be counting machine 3A～3C and the floor position memory of a reference value CR.Thereby, such as utilizing car A to carry out rescuing under the operating condition of car B, can car A be parked on the correct position according to the rolling counters forward value of rescuing car A and being rescued car B.In addition, carry out the position by the signal conditioning of CPU 11A and differentiate, therefore, unnecessary circuit structure has not just needed, and position detection accuracy also is improved.

In addition, in the above-described embodiments, use 3 car A～C that are set up in parallel, but also can adopt the car arranged side by side of any platform.

In addition, self-evident, no matter which kind of situation the number of floor levels that elevator can turn round and the service floor number of each car are, the present invention can both be suitable for.

In addition, key horizon MF be set at each car A～C arranged side by side common descend floor most, but also can be set at arbitrary floor such as bottom.

In addition, can set arbitrarily, both can set mutually different numerical value for, also can set same numerical value for corresponding to the 1st a reference value CO of orlop MF-2 and corresponding to the 2nd a reference value CR of key horizon MF.

Have again, adopted the detected value of rolling counters forward value X, still, also can adopt analog signal arbitrarily as expression car relative distance.

As mentioned above, can obtain such elevator control gear according to the present invention, wherein be provided with the device of the storage specification data relevant with the running service of car, in measuring running, judge according to specification data whether car is in the undermost device of service floor, when judging that car is in orlop, give in the floor position memory device of setting the 1st a reference value corresponding to undermost storage location and detected value, in measuring running, judge according to specification data whether car is in the device of common key horizon, when judging that car is in key horizon, give the device of setting the 2nd a reference value corresponding to the storage location and the detected value of key horizon in the floor position memory, the detected value when arriving key horizon according to car and the count difference value correction of the 2nd a reference value are corresponding to the device of orlop to the content of each storage location of key horizon, be modified to for same position numerical value the detected value of each car position of expression identical accurately, therefore, do not need unnecessary structure just can correctly differentiate the position of being rescued car, can not damage realization cost reduction under the situation of rescuing the function of motion.

In addition, can obtain such elevator control method according to the present invention, it is included in to measure in the running judges according to the data relevant with the running specification of car whether car is in the undermost step of service floor, judge and to give in the floor position memory step of setting the 1st a reference value corresponding to undermost storage location and detected value when car is in orlop, in measuring running, judge according to data whether car is in the step of common key horizon, judge and give the step of setting the 2nd a reference value corresponding to the storage location and the detected value of key horizon in the floor position memory when car is in key horizon, the step of the detected value when obtaining car arrival key horizon and the count difference value of the 2nd a reference value, according to the count difference value correction corresponding to the step of orlop to the content of each storage location of key horizon, owing to will represent that the detected value of each car position is modified to for same position numerical value identical accurately, therefore, do not need unnecessary structure just can correctly differentiate the position of being rescued car, do not damaging realization cost reduction under the situation of rescuing the function of motion.
