Next, the divided construction steps to be performed during the renewal construction period of the elevator will be described with reference to FIG. FIG. 2 is a table showing an example of a series of divided construction steps of the elevator renewal method according to Embodiment 1 of the present invention.

Here, in order to shorten the continuous downtime of the elevator during the renewal work period of the elevator, the renewal work is divided into a plurality of divided construction steps. Each divided construction step is completed within a time that can be continuously secured, and the user can use the elevator after each divided construction step is completed. That is, in order to shorten the continuous downtime of the elevator during the renovation work period of the elevator, it is a prerequisite that the elevator can be used when each divided construction step is completed. For example, in condominiums, elevators need to be available during business hours such as in the morning and evening, when there are many users commuting to work or school, and in eating and drinking tenant buildings, during business hours such as in the evening and at night.

Therefore, when renewing at least a part of the equipment of the elevator, the contents of the renewal are divided as a series of divided construction steps in units in which the elevator can be normally operated after the completion of each divided construction step. . Renewal work is carried out according to this series of divided construction steps. As shown in FIG. 2, the contents of the renewal work are divided into three divided construction steps, for example, divided construction step S1 to divided construction step S3. However, depending on the specifications of the elevator, it may be necessary to further divide each divided construction step.

In the division construction step S1, a new control panel is installed separately from the existing control panel. Next, the existing old hoist, which is an example of the first old equipment, is renewed. The main equipment to be renewed in the division construction step S1 is a control panel, a hoist, a main rope, a weighing device, and the like. After completion of the division construction step S1, the elevator is ready for normal operation.

In the division construction step S2, the existing old car equipment, which is an example of the second old equipment, is renewed. The divided construction step S2 is performed after the divided construction step S1. The main equipment to be renewed in the divided construction step S2 is a car controller, a door driving device, a car operating panel, a moving cable, a ceiling device, a landing detection device, and the like. After completion of the division construction step S2, the elevator is ready for normal operation.

In the division construction step S3, the existing old hall/hoistway equipment, which is an example of the third old equipment, is renewed. The divided construction step S3 is performed after the divided construction step S2. The main equipment to be renewed in the division construction step S3 is the hall operating panel, end point switch, hoistway cable, and the like. After completion of the division construction step S3, the elevator is ready for normal operation.

In this way, when one divided construction step of the series of divided construction steps is completed, the elevator is ready for normal operation. Therefore, when one divided construction step is completed, there is a time slot in which the elevator can be used by users, and the continuous downtime of the elevator can be shortened.

(Renewal method)
Next, an elevator renewal method according to Embodiment 1 will be described with reference to FIGS. 3 to 7. FIG. FIG. 3 is a block diagram showing the initial state of the elevator apparatus to which the elevator renewal method according to Embodiment 1 of the present invention is applied.

A communication method applied to the old control board 110 is, for example, a serial communication method. Hereinafter, the communication method applied to the old control board 110 will be referred to as the “old communication method”. The old control board 110 controls the elevator apparatus by communicating with the old hoisting machine 200, the old car equipment 300, and the old hall/hoistway equipment 400 using the old communication method.

(Divided construction step S1: Installation of control panel and renewal of hoisting machine)
Next, the division construction step S1 will be described with reference to FIG. FIG. 4 is a block diagram showing the state of the elevator system after performing the divided construction step S1 on the initial state of the elevator system of FIG.

In the division construction step S1, a process of installing the new control panel 100A at a position different from the old control panel 100 in the machine room is performed. The new control board 100A includes a new control board 110A, which is a control board for controlling the elevator device. By performing this step, the old control panel 100 and the new control panel 100A are mixed.

Subsequently, a process of replacing the old control board 110 of the old control board 100 with the communication conversion board 120 is performed. Specifically, in this process, the old control board 110 is removed from the old control board 100 and the communication conversion board 120 is installed inside the old control board 100 . By performing this process, the old control panel 100 is provided with the communication conversion board 120 . The size of the old control board 110 is, for example, the same as the size of the communication conversion board 120 .

Subsequently, a step of connecting the new control board 110A of the new control board 100A and the communication conversion board 120 of the old control board 100 is performed. Subsequently, a step of connecting the communication conversion board 120 of the old control panel 100 to the old car equipment 300 and the old hall/hoistway equipment 400 is performed.

Subsequently, a step of renewing the old hoisting machine 200 to the new hoisting machine 200A is performed. Specifically, in this step, the old hoisting machine 200 is replaced with the new hoisting machine 200A. Subsequently, a step of connecting between the new control board 110A of the new control panel 100A and the new hoisting machine 200A is performed.

The communication method applied to the new control board 110A is, for example, a serial communication method such as a CAN (Controller Area Network) communication method. Hereinafter, the communication method applied to the new control board 110A will be referred to as "new communication method". The new communication method is capable of transmitting and receiving a larger amount of data than the old communication method, and has a higher data transmission speed than the old communication method. The new control board 110A controls the elevator apparatus by communicating with the new hoisting machine 200A, the new car equipment 300A described later, and the new landing/hoistway equipment 400A described later, using the new communication method.

Next, the configuration of the communication conversion board 120 will be described with reference to FIG. FIG. 5 is a block diagram showing the configuration of the communication conversion board 120 of FIG. The communication conversion board 120 is configured to mutually convert the communication method between the old communication method and the new communication method. Specifically, as shown in FIG. 5, the communication conversion board 120 includes a CPU (Central Processing Unit) 121 and a RAM (Random Access Memory) 122 .

The CPU 121 converts the format of the data from the old car equipment 300 into data compatible with the new control board 110A and stores the data in the RAM 122 . Note that the format refers to a data structure such as the number of bits. The CPU 121 converts the format of the data from the new control board 110A into data compatible with the old car equipment 300, and stores the data in the RAM 122. FIG.

The CPU 121 retrieves the format-converted data from the RAM 122 and outputs it in response to a request from the new control board 110A. In response to a request from the old car equipment 300, the CPU 121 extracts the above format-converted data from the RAM 122 and outputs it. As a result, the new control board 110A of the new control board 100A can communicate with the old car equipment 300 via the communication conversion board 120 even if the applied communication system is different.

Similarly, the CPU 121 converts the format of data from the old hall/hoistway equipment 400 into data corresponding to the new control board 110A, and stores the data in the RAM 122 . The CPU 121 converts the format of the data from the new control board 110A into data compatible with the old hall/hoistway equipment 400 and stores the data in the RAM 122 .

The CPU 121 retrieves the format-converted data from the RAM 122 and outputs it in response to a request from the new control board 110A. The CPU 121 retrieves the format-converted data from the RAM 122 in response to a request from the old hall/hoistway equipment 400 and outputs the data. As a result, the new control board 110A of the new control board 100A can communicate with the old hall/hoistway equipment 400 via the communication conversion board 120 even if the applied communication system is different.

As a specific example, consider a case where the old car equipment 300 includes an existing old car operating panel. In this case, the new control board 110A communicates with the old car operating panel via the communication conversion board 120. FIG. As an example, the new control board 110A gives the old car operating panel a display command to display information on the display of the old car operating panel through such communication. As another example, the new control board 110A receives, from the old car operating panel, operation information indicating that a button, switch, or the like of the old car operating panel has been pressed.

The following examples are conceivable as specific communication methods for the old communication method and the new communication method. That is, as a first example, both the old communication method and the new communication method are considered to be serial communication methods. As a second example, both the old communication method and the new communication method are parallel communication methods. As a third example, it is conceivable that the old communication method is the serial communication method and the new communication method is the parallel communication method. As a fourth example, it is conceivable that the old communication system is the parallel communication system and the new communication system is the serial communication system.

Thus, the first divided construction step S1, which is one of the series of divided construction steps, includes at least the following four processes A1 to A4.
(Step A1) A step of installing a new control panel 100A having a new control board 110A to which the new communication method is applied, separately from the old control panel 100 having the old control board 110 to which the old communication method is applied (Step A2). The old hoisting machine 200, which is an example of the first old equipment, is renewed to the new hoisting machine 200A, which is an example of the first new equipment, and the new hoisting machine 200A and the new control board 110A of the new control panel 100A. A step of connecting between (step A3) a step of replacing the old control board 110 of the old control board 100 with a communication conversion board 120 that mutually converts the communication method between the old communication method and the new communication method (step A4) Connection between the communication conversion board 120 of the old control panel 100 and the old car equipment 300 as an example of the second old equipment and the old hall/hoistway equipment 400 as an example of the third old equipment. process

When the above-described steps are carried out, the new control board 110A of the new control board 100A communicates with the new hoisting machine 200A, and through the communication conversion board 120, the old car equipment 300 and the old landing, which have different communication methods, are transferred to each other. • can communicate with each of the hoistway equipment 400;

Therefore, after the divided construction step S1 is completed, the new control panel 100A can be put into a state in which the elevator can be controlled while the old control panel 100 and the new control panel 100A are mixed. can be made drivable.

(Divided construction step S2: car equipment renewal)
Next, the division construction step S2 will be described with reference to FIG. FIG. 6 is a block diagram showing the state of the elevator system after performing the divided construction step S2 on the state of the elevator system of FIG.

In the division construction step S2, a process of renewing the old car equipment 300 to the new car equipment 300A is performed. Specifically, in this step, the old car equipment 300 is replaced with the new car equipment 300A. Subsequently, a step of connecting the new control board 110A of the new control board 100A and the new car equipment 300A is performed.

Thus, the second divided construction step S2, which is one of the series of divided construction steps, includes at least the following process B1.
(Step B1) The old car equipment 300, which is an example of the second old equipment, is renewed to the new car equipment 300A, which is an example of the second new equipment, and the new car equipment 300A and the new control board of the new control panel 100A. Step of connecting between 110A

When the above steps are carried out, the new control board 110A of the new control board 100A communicates directly with the new hoisting machine 200A and the new car equipment 300A, and via the communication conversion board 120 of the old control board 100, It is possible to communicate with the old hall/hoistway equipment 400 that uses a different communication method.

Therefore, after the completion of the divided construction step S2, the new control panel 100A can control the elevator in a state where the old control panel 100 and the new control panel 100A are mixed, and as a result, the elevator can operate normally. can be made drivable.

(Divided construction step S3: Renewal of platform and hoistway equipment)
Next, the division construction step S3 will be described with reference to FIG. FIG. 7 is a block diagram showing the state of the elevator system after performing the divided construction step S3 on the state of the elevator system of FIG.

In the division construction step S3, a step of renewing the old hall/hoistway equipment 400 to the new hall/hoistway equipment 400A is performed. Specifically, in this step, the old hall/hoistway equipment 400 is replaced with the new hall/hoistway equipment 400A. Subsequently, a step of connecting between the new control board 110A of the new control panel 100A and the new hall/hoistway equipment 400A is performed.

Thus, the third divided construction step S3, which is one of the series of divided construction steps, includes at least the following process C1.
(Step C1) The old hall/hoistway equipment 400 that is an example of the third old equipment is renewed to the new hall/hoistway equipment 400A that is an example of the third new equipment, and the new hall/hoistway equipment 400A is renewed. , the process of connecting between the new control board 100A and the new control board 110A

When the above steps are performed, the new control board 110A of the new control panel 100A can directly communicate with each of the new hoisting machine 200A, the new car equipment 300A, and the new landing/hoistway equipment 400A.

Therefore, after the divisional construction step S3 is completed, the new control panel 100A can control the elevator in a state where the old control panel 100 and the new control panel 100A are mixed, and as a result, the elevator can operate normally. can be made drivable.

When all the series of divided construction steps from the divided construction step S1 to the divided construction step S3 are completed, the renewal of the elevator is completed. In this way, when the elevator renewal is completed, all the devices to be renewed are connected to the new control panel 100A, so the old control panel 100 becomes unnecessary. It is possible to remove the old control panel 100 that is no longer needed. The timing for removing the old control panel 100 may be, for example, when the renewal is completed, or when the elevator is being maintained. Also, the communication conversion board 120 of the old control panel 100 can be reused.

Note that either the divided construction step S2 or the divided construction step S3 may be performed first. Note that it is not always necessary to perform all of the divided construction step S2 and the divided construction step S3, and some steps may be omitted.

The first example of the type of old equipment is a hoisting machine, the second example of the type of old equipment is car equipment, and the third example of the type of old equipment is hall/hoistway equipment. However, it is not limited to this. That is, one of the three types of first old equipment is selected from hoisting machines, car equipment, and hall/hoistway equipment, and one of the remaining two types is selected as the second old equipment. and the third old device may be selected from the remaining one type.

As described above, according to the first embodiment, in the elevator renewal method, the first divided construction step includes a step of installing a new control panel separately from the old control panel, and a step of installing the first old equipment in the first A process of renewing to a new device and connecting between the first new device and a new control board of the new control panel, a process of replacing the old control board of the old control board with a communication conversion board, and a process of replacing the old control board with the communication conversion board. and connecting between each of the communication conversion board and each of the second old device and the third old device. Further, after the first division construction step is completed, the new control board of the new control panel communicates with the first new equipment, and communicates with each of the second old equipment and the third old equipment via the communication conversion board. By communicating, the new control board is in a state where it can control the elevator.

As a result, it is possible to shorten the continuous downtime of the elevator during the renovation work period of the elevator. In addition, since the new control panel 100A can be installed independently of the old control panel 100 without removing the old control panel 100, the time required to complete the installation of the new control panel 100A is shortened. be able to. In addition, since the old hoisting machine 200 can be renewed to the new hoisting machine 200A after the new control panel 100A is installed, the operating performance of the elevator can be improved at an early stage.

Further, in the renewal method described in Patent Document 1, it is necessary to connect the cables of the old car equipment and the old hall equipment to the new control panel. However, when connecting the cable to the new control panel, the cable connector type and connector pin number do not match, so a dedicated harness must be prepared. In contrast, in the renewal method according to the first embodiment, there is no need to connect the cables of the old car equipment 300 and the old hall/hoistway equipment 400 to the new control panel 100A. Therefore, preparation of a dedicated harness becomes unnecessary.
