The specific embodiment
Below, be elaborated by graphic embodiment for elevator control gear of the present invention.At this, Fig. 1 is system's pie graph of having represented an embodiment of the present invention, and Fig. 2 is the diagram of circuit that is used to illustrate this embodiment action.
In Fig. 1, the elevator control gear 10 of this embodiment has: MPU11 and flash of light memory device ROM12, RAM13, interface 14, and interconnected these parts by bus 16.At this, so-called MPU is a microprocessor unit, and at this moment, elevator control gear 10 has come down to install MPU11 and the tellite of glisten memory device ROM12, RAM13, interface 14.
And, at first MPU11 moves as the operation processing unit of carrying out the required control program of elevator operation, the work that the memory device ROM12 that glistens at this moment stores above-mentioned control program, RAM13 carries out the work of storage control program and data, and these data are these control program operation results.
At first, flash of light memory device ROM12, as playing a role by the electric memory device of rewriting memory contents, come work at this storage area as control program, therefore have the storage area a of formation the 1st program storage part and two storage areas of the storage area b of formation the 2nd program storage part.Then, RAM13 plays a role with data memory (transaction memory) as upgrading, here as coming work in the relevant data storage areas of control program, therefore have two storage areas that become the storage area of the 2nd data store c and become the storage area d of the 1st data store, have the storage area of storage area e in addition as data such as sequential operation results.
In addition, in this RAM13, also has the storage area that is not illustrated, store the rewriting program therein, promptly be stored in program required in the following processing: should be stored in the data such as this control program of flash of light memory device ROM12 and RAM13 according to the operation result of control program, and duplicate and be stored in the arbitrary region of ROM12 and RAM13.
Then, interface 14 carries out connecting the work of external device (ED) 15 on this elevator control gear 10, should can store into the RAM13 from external device (ED) 15 by interface 34 the new control program of rewriting on the old control program and the program of in rewriting, using (below, be called the rewriting program) thus.
Externally install for this reason and use Personal Computer (Personal Computer of established procedure has been installed) in 15 usually, for example service personnel goes to the machine room of lift appliance, is connected to the basic enterprising line operate of interface 14.
Then, the action to this embodiment describes.Control to elevator describes as fundamental operation at first at the beginning, and at this, this elevator control gear 10 can be worked when having supplied with power supply, and MPU11 begins the required processing of elevator control.Then, the MPU11 of this moment, the control program that will store in the storage area 12a of ROM12 duplicates and is stored among the storage area 13c of RAM13 earlier.
Then, after storage is finished, the control program of the regional a of MPU11 by being arranged in ROM12, with program transfer to the storage area c of RAM13 with reference to the destination, use the control program that is stored in this storage area c to carry out the operation control of elevator.Therefore, this moment the elevator operation mode that obtains, the control program that just is stored in storage area c thus the time decides.
The MPU11 of this moment does not carry out the program reference for ROM12.For this reason, MPU11 is when having supplied with power supply to elevator control gear 10, and operation procedure is so that must be with reference to the regional a of ROM12 when restarting (microcomputer restarts) MPU11.
Then, rewriting for this embodiment control program is handled, flow process by Fig. 2 describes, rewriting based on the control program of this flow process is handled, be to use the processing of promptly rewriting program and carrying out to the rewriting specific program of RAM13 storage from external device (ED) 15 by MPU11 by interface 34, therefore, when rewrite control program, service personnel begins to handle required operation after external device (ED) 15 has been imported new control program and rewriting program.
Therefore, the current overwrite request (S1) of sending control program from external device (ED) 15 by interface 14.Like this, MPU11 will be stored in from the new control program that external device (ED) 15 sends by interface 14 the storage area d of RAM13 (S2).
Then, the current new control program of storing in the storage area d of RAM13 is carried out and verification verifications (S3) such as (sum check), this result is judged as the occasion of Y (affirming), promptly the data of the new control program of storing in being judged as storage area d constitute and dispose normal occasion, and the old control program that MPU11 will be arranged in the storage area a of ROM12 duplicates and be stored in the storage area b (S4) of ROM12.On the other hand, the result is judged as the occasion of N (negating), and promptly the new control program of storing in being judged as storage area d has had unusual occasion, to external device (ED) 15 output abnormality signals (S3a), after service personnel is reported the processing of need reforming, finish stores processor at this.
If in the storage area b of ROM12, stored old control program like this, then carry out once more here and verifications (S5) such as verification, when the data that can be judged as normal storage, duplicate and store control with program (S6) from the storage area d of RAM13 to the storage area b of ROM12, finish the rewriting of ROM12 is handled.
At this, use the control program of in the storage area c of RAM13, storing, control until current action by MPU11.In addition, as mentioned above because by controlling the elevator of this moment at the control program of the storage area c of RAM13, do not carry out the rewriting processing of ROM12 at this so can have any obstacle ground elevator in service.
Like this, when the rewriting of new control program is handled if be through with, then after this can switch to the operation control that new control program carries out elevator from old control program at any time, but in this embodiment at this, after this cut off the power supply of elevator control gear 10 is supplied with, before drop into again and to restarting before (microcomputer restarts) MPU11, do not transfer to the processing of S7.
Therefore, according to this embodiment, during the rewriting from treatment S 1 to the control program of handling S6 is handled, the elevator operation control of old control program continues to maintain the original state, and does not interrupt the service of elevator.
So identical with above-mentioned fundamental operation switch to the occasion that new control program carries out the operation control of elevator from old control program, temporarily disconnected is supplied with the power supply of elevator control gear 10, then drops into once more, perhaps carries out restart (S7) of MPU11.Like this, be that opportunity begins later processing with it, at first the control program that will store in the storage area a of ROM12 duplicates and is stored among the storage area c of RAM13 (S8).
So, after this control program of storing among the storage area c of RAM13 becomes executing state, elevator operation mode becomes the operation control according to new control program, the service that need not interrupt elevator just can be transferred to the operation control of new control program from the elevator operation control of old control program, therefore, according to this embodiment, can reach the purpose of expectation.
In this embodiment, after this also carry out processing from S9 to S13.That is, after the processing of end S8, if the elevator of new control program operation beginning, what unusual (S9) whether the elevator operation of next investigating this new control program have.
Then, if the result that this S9 handles be N, promptly the elevator operation of new control program finishes the processing of the rewriting of finishing control program just when unusual at this.Therefore, formally transfer to the operation control of new control program here for the first time.
On the other hand, if the result that S9 handles is Y, be that the elevator operation of new control program has had when unusual, here, at first to external device (ED) 15 output abnormality signals, report the not success of storage of new control program to service personnel, then, will be stored in control program among the storage area b of ROM12 in advance, be that old control program duplicates and is stored in storage area a and goes up (S11).
So, learn that the storage of new control program does not have the service personnel of success this moment in advance, this temporary transient interruption the power supply of elevator control gear 10 is supplied with, when dropping into once more or carry out the restarting of MPU11 (S12), with it is that opportunity begins later processing, and the control program that will store in the storage area a of ROM12 duplicates and is stored on the storage area c of RAM13 (S13).
So, after this because the control program in the storage area c of RAM13, stored, be that old control program becomes executing state, so the operational mode of elevator turns back to the operation of in the past identical old program and controls.
Therefore, according to present embodiment, can the get out of hand program even not success is handled in the rewriting of control program yet, owing to just turn back to the operation control of old control program, so can suppress to provide the elevator device that is imbued with convenience in minimum degree ground because the service that elevator stops to be brought reduces.
So, as embodiments of the present invention, as shown in Figure 4, can use remote servicing device 45 to replace external device (ED) 15 (Fig. 1).The remote servicing device 45 of this moment, be the device of in remote place far away, the place that elevator is set, settling, wait the rewriting of executive control program to handle because can transmit new control program from remote place, thus the place that is provided with of elevator need not be gone to, just can rewrite control program.
Improvement as the remote new control program that transmits this moment, the signal or the data that send by from remote servicing device 45 are for example arranged, the program that to restart MPU11 is installed in the method in the control program in advance, at this moment, according in elevator operation control, using the continuous time of calling or the weighing load value of car etc., confirmed on the basis of no one in the car, can be in the switching of carrying out new and old control program opportunity from remote place of safety.
In addition, when new control program having been made the option service routine (optionservice programme) that is applicable to when safeguarding contract, conclude safeguard contract after, the user can rewrite elevator at the arbitrary timing of expectation.In addition, when contract is safeguarded in releasing, as shown in Figure 5, can leave out above-mentioned option service routine, when when the signal of terminating an agreement is safeguarded in remote servicing device 45 input expression (Sk2), the former old control program that is stored in the suitable above-mentioned option service routine among the ROM12 storage area b is replicated among the regional a of ROM12 (Sk3).
At this moment, shown in the S5 of Fig. 4, carry out coming determining program whether by normal rewrite (Sk4) with verification.The occasion that is treated to N of Sk4, promptly have when unusual, here to remote servicing device 45 output abnormality signals (Sk5), and the request that can return to the past.
The occasion that is treated to Y of Sk4, promptly to the regional a normal replication of ROM12 during old control program, by temporarily disconnected the power supply of elevator control gear 10 is supplied with, then drop into or carry out restart (Sk6) of MPU11 once more, can move control (Sk7) to elevator with the former old control program that is applicable to above-mentioned option service routine.
