Description

  The present invention relates to an elevator control program updating apparatus that rewrites a control program used for elevator operation control and monitoring control to a new control program.

  Many elevator control devices store a control program in a non-volatile memory element such as an EPROM or a flash memory (Flash ROM), and the microcomputer reads the control program from the non-volatile memory element and executes it when the elevator is in operation. Elevator operation control and monitoring control are performed.

  By the way, when rewriting an already stored control program (hereinafter referred to as an existing control program) with a new control program, the nonvolatile memory element storing the existing control program is replaced with a nonvolatile memory element storing the new control program. Or by connecting a storage medium such as a memory card that stores a new control program to the elevator control device and copying the new control program stored in the storage medium to an existing non-volatile storage element. Yes. As a result, during the rewriting of the control program, it is necessary to stop the operation of the elevator and perform a rewriting operation of a new control program, which causes a problem of lowering the elevator service.

Therefore, conventionally, several control program update devices have been proposed in order to solve the above problems.
The one control program update device selectively selects a first control program storage unit that stores an existing control program, a second control program storage unit that stores a new control program, and these two control program storage units. The switching means normally selects the first control program storage unit, connects to the bus line derived from the microcomputer, and sets the already-executed control program to an executable state.

  In this state, when rewriting to a new control program, an external device including a storage medium storing the new control program is connected to the elevator control device, and the second control program storage unit stores the new control program from the external device. Transfer and write to. Then, the switching means selects the second control program storage unit during operation of the elevator and connects to the bus line derived from the microcomputer. The microcomputer performs a rewrite process by copying a new control program stored in the second control program storage unit to the first control program storage unit. The switching means, after rewriting to a new control program, selects the first control program storage unit and connects it to the bus line derived from the microcomputer. Here, the microcomputer performs operation control and monitoring control of the elevator according to a new control program (Patent Document 1).

  Another control program update device has a configuration in which an electrically rewritable program storage device having an operation control program area, a rewrite program storage area, and a rewrite spare area, an address changing means, and a microcomputer are provided. . The microcomputer executes an operation control program already stored in the operation control program area of the program storage device, and performs operation control and monitoring control of the elevator.

  When rewriting to a new operation control program, an external program transfer device is connected to the elevator control device, and when there is a rewrite request from the external program transfer device, the address changing means stores the operation control program stored in the operation control program area. The address shown is changed to the address corresponding to the reserved area for rewriting, and the new operation control program is transferred to the reserved area for rewriting. After the transfer, the operation control program in the operation control program area is rewritten with a new operation control program in the rewriting spare area. During this rewriting, the operation control program is stopped and the rewriting spare area indicated by the address changed in the previous period is displayed. The new operation control program is executed (Patent Document 2).

These two control program update devices can be rewritten without stopping the operation of the elevator when a new control program is rewritten.
JP 2000-128447 A (see FIG. 1) Japanese Patent Laying-Open No. 2001-10772 (see FIG. 1)

  However, in any of the control program update apparatuses as described above, it is necessary to newly add unnecessary circuits unrelated to execution of the control program, such as switching means and address changing means. As a result, with the addition of unnecessary circuits, the cost of the control device increases, and the malfunction of the newly added circuit may cause a failure or trouble of the control device, resulting in a problem of reduced reliability. is there.

  The present invention has been made in view of the above circumstances, and provides an elevator control program updating apparatus that updates a new control program without adding a circuit unrelated to the execution of the control program and without stopping the operation of the elevator. For the purpose.

A first control program storage unit for storing a control program; a second control program storage unit for storing a second control program; a rewrite program storage unit for storing a rewrite program; the first control program; When a new control program is received from an external program transfer device and a selection program storage unit that stores a selection program that defines the selection order of the second control program, the first control program storage unit according to the selection program 1 control program and a second control program of the second control program storage unit The control program selected according to the selection order of the selection program is rewritten to the new control program by the rewrite program, while using the control program of the other control program storage unit that is not being rewritten, It is an elevator control apparatus provided with the operation control processing part which is the said computer which performs operation control.

  According to the present invention, the first control program storage unit or the second control program storage unit selected according to the selection program and selected by the rewriting program can be obtained. While the control program in the second control program storage unit is being rewritten with a new control program, the control program that is not being rewritten is executed to perform operation control or monitoring control, so that new control can be performed without stopping the operation of the elevator. It can be rewritten to a program.

(2) Further, according to the present invention, a first setting data storage unit that stores first setting data to be used when executing the first control program is newly added to the component of the item (1), and the first A second setting data storage unit that stores second setting data used when executing the second control program, and the first setting data storage unit or the second setting data when a new control program is rewritten by the rewriting program. An elevator control device to which means for rewriting the first setting data or the second setting data stored in a storage unit with new setting data used when executing the new control program is added.

  By adopting the configuration as described above, the present invention can simultaneously rewrite the setting data used when executing a new control program when rewriting a new control program.

  ADVANTAGE OF THE INVENTION According to this invention, the elevator control program update apparatus which can be updated to a new control program, without stopping operation | movement of an elevator, without adding the circuit unrelated to execution of a control program can be provided.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of an elevator control program updating apparatus according to the present invention.
In the figure, reference numeral 1 denotes an elevator control program update device applied to an elevator control device or an elevator control board (hereinafter referred to as a control device). The elevator control program update device 1 includes a nonvolatile memory element 2, an operation control processing unit 3, a volatile memory element 4, and an interface unit 5.

  The nonvolatile memory element 2 is configured by an electrically rewritable flash memory (Flash ROM) for storing a predetermined program and setting data. An EPROM may be used instead of the flash memory. The EPROM is a rewritable PROM that can be erased by irradiation with ultraviolet rays or the like.

  The nonvolatile memory element 2 includes a selection program storage unit 21, a rewrite program storage unit 22, a first control program storage unit 23 that stores a first control program, and a second control program that stores a second control program. A storage unit 24, a first setting data storage unit 25 that stores first setting data, a second setting data storage unit 26 that stores second setting data, and a rewriting data storage unit that stores data being rewritten Storage areas such as 27 are provided. Thus, by providing all the memory | storage parts 21-27 in the one non-volatile memory element 2, the number of parts of an elevator control apparatus can be reduced.

  The selection program storage unit 21 stores a selection program that defines the selection order of a first control program and a second control program to be described later.

  The rewrite program storage unit 22 performs a rewrite process when the control program stored in the first control program storage unit 23 or the second control program storage unit 24 is rewritten to a new control program transferred from the outside. The rewriting program is stored.

  The first control program storage unit 23 stores a first control program describing a procedure for executing elevator operation control and monitoring control. The second control program storage unit 24 stores a second control program that describes the same procedure as the first control program. The first control program and the second control program are the same new control program after rewriting of the new control program, and the addresses indicating the storage areas in the nonvolatile memory element 2 are different. Only.

  The first setting data storage unit 25 stores first setting data used as necessary in the execution stage of the first control program. The second setting data storage unit 26 stores second setting data used as necessary in the execution stage of the second control program. These first setting data and second setting data also become the same new setting data after the rewriting of the new setting data is completed as in the control program.

  In the rewriting data storage unit 27, predetermined code data is set when rewriting of a new control program is completed. The predetermined code data is data having a function of confirming rewriting to a new control program in addition to a function of prompting rewriting of a control program not rewritten to a new control program to a new control program.

  The operation processing control unit 3 is composed of a CPU, and a first control program or a second control program storage unit 24 stored in a first control program storage unit 23 that constitutes a part of the nonvolatile storage element 2. The operation control and the monitoring control are performed by executing the second control program stored in. The operation control processing unit 3 has a function of executing various necessary programs other than the control program stored in the non-volatile storage element 2 and performing a process of updating a new control program.

  The volatile storage element 4 has a role as a data buffer memory that temporarily stores data of processing results and processing results by the operation control processing unit 3. The volatile memory element 4 is a memory element that can be written and read at any time, and for example, a static RAM is used. DRAM or SDRAM may be used instead of the static RAM.

  The interface unit 5 has a function of taking in a new control program transferred from the external storage medium 6 connected to the elevator control program update device 1 and sending it to the operation control processing unit 3.

  Note that a memory card is generally used as the external storage medium 6. When a memory card is used, the interface unit 5 is an interface circuit corresponding to the memory card standard. The external storage medium 6 can be replaced by a personal computer. That is, a configuration may be adopted in which a personal computer is connected to the interface unit 5 of the elevator control program update device 1 and a new control program stored in advance is transferred to the control program update device 1. In this case, the interface unit 5 has a function of a communication controller for communicating with a personal computer.

  Further, instead of the external storage medium 6, a new control program can be transferred from the monitoring system of the remote monitoring center, or a new control program can be transferred from the elevator control device of another elevator. Therefore, hereinafter, the program transfer device 6 is collectively referred to as including a memory card, a personal computer, a remote monitoring center monitoring system, and other elevator control devices. In this way, if a new control program is transferred from the personal computer, the monitoring system of the remote monitoring center, and the control device of other elevators, workers go to the building where the elevator is installed and load the memory card. It is possible to omit the work and rewrite a new control program.

  As the operation control processing unit 3, as shown in FIG. 2, a first control program execution means 11 for executing a first control program stored in a first control program storage unit 23, and an external program transfer device 6 is connected to the elevator control program update device 1, and then a rewrite request for judging whether or not a predetermined rewrite control signal has been received from the program transfer device 6 and whether or not there has been a rewrite request for a new control program. A judging means 12, a second control program rewriting means 13, a predetermined code data writing means 14, and a first control program rewriting means 15 are provided.

  The second control program rewriting unit 13 executes a process of rewriting the second control program stored in the second control program storage unit 24 with a new control program received from the program transfer device 6. The predetermined code writing unit 14 indicates that the new control program is being rewritten in the rewriting data storage unit 27 after the second control program rewriting unit 13 finishes writing the new control program to the second control program storage unit 24. Write predetermined code data. The first control program rewriting unit 15 recognizes the predetermined code being rewritten written by the predetermined code writing unit 14 and transfers the first control program stored in the first control program storage unit 22 to the second control program. It has a function of rewriting a new control program stored in the program storage unit 23.

Next, the operation of the elevator control program update device as described above will be described with reference to FIG.
When the elevator control device is activated, the operation control processing unit 3 executes the first control program execution unit 11 based on the selection order of the selection programs stored in the selection program storage unit 21. The first control program execution means 11 in the operation control processing unit 3 determines whether or not predetermined code data indicating rewriting is present in the rewriting data storage unit 27 (S1). When there is no predetermined code data indicating rewriting in the rewriting data storage unit 27, the first control program stored in the first control program storage unit 23 is read and described in the first control program. According to the procedure, elevator operation control and monitoring control are performed (S2). As shown in FIG. 4, the first control program in the first control program storage unit 23 is transferred to the volatile storage element 7, and the first control program is read from the volatile storage element 7 and executed. It may be a method.

  At this time, the first control program execution means 11 stores the first setting data when setting data (for example, calculation parameters) is necessary to perform operation control or the like during execution of the first control program. Referring to the unit 25, necessary setting data is read out and used for operation control or the like. Note that data and input / output data obtained in the process of operation control and the like are stored in the volatile storage element 4.

  Further, the first control program execution unit 11 executes a first control program by, for example, a volatile memory such as a static RAM different from the volatile memory element 4 described above as shown in FIG. The element 7 may be provided, and the first control program may be read from the first control program storage unit 23 and written to the volatile storage element 7, and operation control or the like may be performed based on the written first control program. .

  Subsequently, the operation control processing unit 3 executes the rewrite request determination unit 12. The rewrite request determination means 12 of the operation control processing unit 3 determines whether or not a rewrite request signal for a new control program has been received from the external program transfer device 6 (S3).

  By the way, when a new control program is rewritten as the period elapses, a predetermined rewrite request signal is sent from the program transfer device 6 through the interface unit 5. Therefore, when the rewrite request signal is detected, step S3 is performed. It is determined that there is a rewrite request. When the rewrite request determination unit 12 determines that there is a rewrite request, it executes the rewrite program in the rewrite program storage unit 22 and rewrites a new control program (S4). In step S3, when the rewrite request signal is not received, it is determined that there is no rewrite request, and the process returns to step S2 and continues to execute the first control program.

  As for the rewrite request determination, not only the rewrite request signal from the program transfer device 6 but also the operation signal is detected when a switch (not shown) attached to the elevator control device 1 is operated, for example. It may be determined that there is a rewrite request.

  The process of executing the rewrite program when the rewrite request signal or the operation signal from the program transfer device 6 is detected can be realized by describing it in the first control program in advance.

  The operation control processing unit 3 executes the rewriting program as described above, and executes the second control program rewriting means 13. When the second control program rewriting unit 13 is executed, the operation control processing unit 3 alternately executes the first control program and the rewriting program every predetermined time, and apparently the two programs are executed simultaneously. The process is done.

  Therefore, the second control program rewriting unit 13 in the operation control processing unit 3 executes the rewriting program and receives the second control program stored in the second control program storage unit 24 from the program transfer device 6. Rewrite the control program. When the rewriting program is executed, if the setting data used in the process of executing the new control program is stored in the program transfer device 6, the setting data in the second setting data storage unit 26 is rewritten at the same time. Thereby, the consistency between the new control program and the setting data can be maintained.

  Thereafter, it is determined whether or not rewriting of the new control program has been completed (S5). If all of the new control program has not yet been rewritten, the process proceeds to step S6 and the execution time of the rewriting program has elapsed for a predetermined time t1. Determine whether or not. If it is determined that the predetermined time t1 has not elapsed, the process returns to step S4, and the rewriting program is continuously executed. On the other hand, when it is determined that the predetermined time t1 has elapsed, the first control program is executed again (S7), and it is determined whether or not the execution time of the first control program has passed the predetermined time t1 (S8). ). If it is determined that the predetermined time t1 has not elapsed, the process returns to step S7, and the execution of the first control program is continued. Therefore, the second control program rewriting means 13 continues the elevator operation control and the monitoring control, and the new control program is rewritten almost at the same time.

  On the other hand, if it is determined in step S5 that the rewriting of the new control program has been completed, the operation control processing unit 3 executes the predetermined code writing means 14. When the predetermined code writing means 14 determines that the rewriting to the new control program has been completed, the predetermined code writing means 14 writes a predetermined code in the data storage unit 27 being rewritten (S9), whereby a new control program to the first control program storage unit 23 is obtained. Encourage rewriting. Here, after writing a predetermined code, it is determined whether or not the elevator is stopped (S10). If the elevator is in operation in response to a call, the process proceeds to step S2, and the same process is repeated. .

  In step S10, the elevator stops after answering all calls, and when the door is closed, it is determined that the elevator has stopped, and the operation control processing unit 3 is restarted.

  After the restart, the operation control processing unit 3 determines whether a predetermined code indicating rewriting is written in the rewriting data storage unit 27 based on the selection program in the selection program storage unit 21 (S1). Here, when it is confirmed that predetermined code data is written in the rewriting data storage unit 27, the second control program storage unit 23 is selected to execute the second control program (S11). 1 control program rewriting means 15 is executed.

  That is, the first control program rewriting means 15 in the operation control processing unit 3 obtains a new second control program stored in the second control program storage unit 24 and a rewrite program stored in the rewrite program storage unit 22. call. Then, the second control program and the rewriting program are alternately executed at every predetermined time t2, and apparently the two programs are executed simultaneously, and the elevator is operated according to the procedure described in the second control program. In addition to performing control and monitoring control, the first control program stored in the first control program storage unit 23 is rewritten with a new second control program. Note that when the second setting data storage unit 26 stores the second setting data to be used when executing the new second control program, the setting of the first setting data storage unit 25 is performed. Rewrite data.

  That is, the first control program rewriting means 15 in the operation control processing unit 3 executes the second control program (S11), and then whether or not the execution time of the second control program has passed the predetermined time t2. Is determined (S12). Here, when it is determined that the execution time of the second control program has not elapsed the predetermined time t2, the process returns to step S11, and the execution of the second control program is continued. On the other hand, when it is determined that the predetermined time t2 has elapsed, a rewriting program is executed (S13), and a process of rewriting the first control program in the first control program storage unit 23 with a new second control program is executed. To do.

  Thereafter, it is determined whether or not rewriting of the new second control program has been completed (S14). If rewriting has not yet been completed, it is determined whether or not the execution time of the rewriting program has passed the predetermined time t2. If it is determined (S15) and the predetermined time t2 has not elapsed, the process returns to step S13, and the rewriting program is continuously executed. When the execution time of the rewriting program has passed the predetermined time t2, the process returns to step S11, the new second control program is executed again, and the same processing is repeated.

  On the other hand, if it is determined in step S14 that the rewriting of the second control program has been completed, the predetermined code indicating that the rewriting data storage unit 27 is being rewritten is deleted (S16), and then the process proceeds to step S10. It is determined whether or not the elevator is still stopped. Here, if the elevator is in operation, the process returns to step S2, and if the elevator is still stopped, the process returns to step S1, and the series of processes described above are repeated.

  According to the embodiment as described above, when a new control program to be updated is transferred from the external program transfer device 6, the first control program and the rewriting program that are always executed are alternately executed, In addition to performing elevator operation control and the like, the second control program in the second control program storage unit 24 is rewritten with a new control program, so that the second control program storage unit 24 does not interfere with the operation of the elevator. A new control program can be written.

  Then, after writing the new control program in the second control program storage unit 24, the predetermined code data is set in the rewriting data storage unit 27. For example, when the elevator is stopped, the selection program is started and the predetermined code data is set. When the existence of the vehicle is confirmed, the new second control program and the rewritten program in the second control program storage unit 24 that has been rewritten are alternately executed to control the operation of the elevator and the first control program. The first control program in the storage unit 23 is rewritten with a new second control program. Therefore, a new control program can be rewritten to the control program in the first control program storage unit 23 without stopping the operation of the elevator.

(Other embodiments)
(1) In the above embodiment, the new control program transferred from the program transfer device 6 is rewritten according to the selection order of the second control program storage unit 24 and the first control program storage unit 23. After a new control program is written in the first control program in the first control program storage unit 23 being executed, the second control program in the second control program storage unit 24 is rewritten to a new control program. Also good. In this case, instead of the second control program rewriting means 13, the first control program rewriting means is executed after execution of the rewrite request determination means 12. Similarly, instead of the first control program rewriting means 15, the second control program rewriting means is executed after execution of the predetermined code writing means 14.

  Thereby, the same effects as those of the above-described embodiment can be obtained.

(2) In the above embodiment, the selected program storage unit 21, the rewrite program storage unit 22, the first and second control program storage units 23 and 24 for storing the control program, and the setting in one nonvolatile storage element 2. The storage areas such as the first and second setting data storage units 25 and 26 and the data rewriting data storage unit 27 for storing data are formed. For example, as shown in FIG. It is stored in an inexpensive storage element 2a such as a mask ROM, and the first and second control program data are stored in a storage element 2b such as a flash ROM. For example, the first and second setting data to be rewritten in units of 1 byte and data being rewritten may be stored in a storage element 2c such as an EEPROM that can be rewritten in units of 1 byte.

  Thereby, it can implement | achieve using an optimal memory element, reducing cost by dividing various program data and setting data into several memory elements 2a-2c.

(3) In the above embodiment, the selection between the first control program and the second control program is performed according to the selection order defined in the selection program. For example, appropriate storage of the elevator control device 1 is performed. The configuration may be such that the first control program and the second control program are selected in accordance with the designation data defined in the means and the program transfer device 6.

(4) In the above embodiment, the selection switching between the first control program and the second control program is performed when the elevator control device or the operation control processing unit 3 is started or restarted. The configuration may be such that the control program selection is switched using another timing signal. For example, as shown in FIG. 6, the selected program storage unit 21 stores an OS (operation system) 21a and an interrupt handler 21b. The first control program storage unit 23 stores a plurality of tasks 23aa,..., 23an activated by the OS 21a and a plurality of interrupt service routines 23ba, ..., 23bn activated by the interrupt handler 21b. Further, in the same way as the first control program storage unit 23, the second control program storage unit 24 includes a plurality of tasks 24aa,..., 24an activated by the OS 21a and a plurality of interrupts activated by the interrupt handler 21b. Service routines 24ba,..., 24bn are stored.

  Then, the first control program and the second control program are selectively switched for each task unit activated by the OS 21a stored in the selected program storage unit 21. Alternatively, the first control program and the second control program may be selectively switched for each interrupt service routine unit activated by the interrupt handler 21b stored in the selected program storage unit 21.

  With such a configuration, only the tasks 23aa,..., 23an, 24aa,..., 24an including processing that may be rewritten and the interrupt service routines 23ba, ..., 23bn, 24ba,. Since only the storage is required, the storage capacity of the nonvolatile storage element 2 can be reduced.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
