The lower machine room 3b has a lid 4 that covers the manhole. The lid 4 is, for example, the floor panel of the lower boarding/alighting entrance 2b.

The escalator 1 includes a drive unit 5, a plurality of steps 6, a pair of handrails 7, a detection unit 8, and a control panel 9. The drive unit 5 is a device that generates a drive force. The drive unit 5 is provided, for example, in the upper machine room 3a. Each step 6 is a device that moves in a circular motion by the drive force generated by the drive unit 5. Each handrail 7 is a device that moves in a circular motion by the drive force generated by the drive unit 5. Here, one handrail 7 is provided on the left side of the plurality of steps 6. The other handrail 7 is provided on the right side of the plurality of steps 6. The detection unit 8 is a part that detects an event that occurs in the escalator 1. The detection unit 8 may include, for example, a safety switch. The detection unit 8 may include, for example, a skirt guard switch that detects pinching of the escalator 1 in the skirt guard. The detection unit 8 outputs a detection signal to the control panel 9 when an event is detected. The control panel 9 is a device that controls the operation of the escalator 1. The control panel 9 is provided, for example, in the upper machine room 3a. The control panel 9 includes a power switch 10. The power switch 10 is a switch that switches the power supply to the escalator 1.

In normal operation, passengers enter the escalator 1 when moving from one of the upper entrance 2a and the lower entrance 2b to the other. The escalator 1 transports passengers who are standing on one of the steps 6 while holding onto one of the handrails 7, for example, by using the driving force generated by the drive unit 5 under the control of the control panel 9.

The portable operating device 11 is used in maintenance work on the escalator 1. Maintenance work includes, for example, inspection work and repair work. The portable operating device 11 is a device that controls the operation of the escalator 1 during maintenance work. The portable operating device 11 is operated by a maintenance worker.

Figure 2 is a configuration diagram of a portable driving device according to embodiment 1.

The portable operating device 11 comprises a main unit 12 and an attachment device 13. The main unit 12 is a part that accepts operation control operations of the escalator 1 during maintenance work. Operation control operations include, for example, switching the power switch 10 of the escalator 1 and operating the escalator 1. Operation operations of the escalator 1 include, for example, switching between ascending and descending operation, and switching between starting and stopping the drive unit 5. The attachment device 13 is a part that is attached to the escalator 1. The main unit 12 and the attachment device 13 are equipped with wireless communication functions. The attachment device 13 is detachably attached to the main unit 12.

The communication range of the mounting device 13 is set in advance, for example, based on the signal strength that the mounting device 13 can receive or the signal strength that the mounting device 13 transmits. The communication range of the mounting device 13 attached to the escalator 1 in the upper machine room 3a is set, for example, so as not to include the lower entrance 2b of the escalator 1.

The main device 12 includes a display unit 14, a switch button 15, an operation button 16, and an input button 17. The display unit 14 is a section that displays information. The switch button 15 is a section that accepts an operation to switch the power switch 10 of the escalator 1. The operation button 16 is a section that accepts an operation to operate the escalator 1. The input button 17 is a section that accepts an operation to input information. The input button 17 may be, for example, a numeric keypad. The main device 12 transmits operation signals representing operations accepted by the switch button 15, the operation button 16, the input button 17, etc., to the attachment device 13 via wireless communication. In this example, the main device 12 operates by receiving power from a built-in battery (not shown).

The mounting device 13 has a first control unit 18 and a second control unit 19. In this example, the first control unit 18 and the second control unit 19 are separable parts from each other.

The first control unit 18 is a part that switches the power switch 10 of the escalator 1 based on an input operation signal. The first control unit 18 is attached to the power switch 10. In this example, the first control unit 18 is equipped with a wireless communication function. The first control unit 18 may directly receive an operation signal transmitted by wireless communication from the main unit 12. When the first control unit 18 is not attached to the power switch 10, it is detachably attached to the main unit 12. The first control unit 18 operates by receiving power from, for example, an internal battery (not shown). Alternatively, the first control unit 18 may receive power through an electrical outlet provided in the machine room.

The second control unit 19 is a part that outputs a control signal to the control panel 9 of the escalator 1 based on an input operation signal. The second control unit 19 is connected to the control panel 9. In this example, the second control unit 19 is equipped with a wireless communication function. The second control unit 19 may directly receive an operation signal transmitted by wireless communication from the main unit 12. When the second control unit 19 is not connected to the control panel 9, it is detachably attached to the main unit 12. The second control unit 19 operates by receiving power from, for example, an internal battery (not shown). Alternatively, the second control unit 19 may receive power from the control panel 9 to which it is connected.

FIG. 3 is a perspective view of the first control unit according to the first embodiment.
In this example, the power switch 10 is a toggle switch having a lever 20 that is operated up and down. In Figure 3, a first control unit 18 attached to the power switch 10 is shown.

The first control unit 18 is attached, for example, so as to cover the power switch 10 from the front. The first control unit 18 includes a cap 21, an arm 22, and an actuator 23. The cap 21 is a part that is attached to the tip of the lever 20 of the power switch 10. The cap 21 is placed over the tip of the lever 20 of the power switch 10. The arm 22 is a part that supports the cap 21. In this example, the arm 22 supports the cap 21 from both the left and right sides. The actuator 23 is a part that generates a driving force that drives the arm 22. The driving force generated by the actuator 23 moves the cap 21 in the vertical direction through the arm 22. The power switch 10 is switched by the lever 20, which is covered by the cap 21, moving in the vertical direction.

Next, an example of a maintenance operation using the portable driving device 11 will be described with reference to FIGS.
4 to 6 are diagrams illustrating an example of a maintenance operation according to the first embodiment.

Figure 4 shows an example of maintenance work in the upper machine room 3a. The upper boarding/alighting entrance 2a above the upper machine room 3a where the maintenance work is performed is an example of the first boarding/alighting entrance.

The worker carries the portable operating device 11 with the mounting device 13 attached to the main unit 12 to the site where the maintenance work on the escalator 1 is to be performed.

First, the worker performs the installation process. The worker opens the lid 4 of the upper machine room 3a. The worker, for example, manually turns off the power switch 10 in the upper machine room 3a.

Next, the worker removes the first control unit 18 and the second control unit 19 of the attachment device 13 from the main body device 12. The worker carries the removed first control unit 18 and second control unit 19 into the upper machine room 3a. In the upper machine room 3a, the worker attaches the first control unit 18 to the power switch 10. In the upper machine room 3a, the worker connects the second control unit 19 to the control panel 9.

Next, the worker closes the lid 4 of the upper machine room 3a. After that, the worker performs the maintenance process.

Figure 5 shows an example of maintenance work in the upper machine room 3a.

The maintenance process includes controlling the operation of the escalator 1. The control of the operation of the escalator 1 may include, for example, operations to adjust the positions of the multiple steps 6.

During the maintenance process, the power switch 10 of the escalator 1 is usually turned off. Therefore, in the operation control of the escalator 1, the worker operates the switch changeover button 15 of the main unit 12 to turn on the power switch 10 of the escalator 1. At this time, the main unit 12 requests the input of a secret code. The request to input the secret code is displayed, for example, on the display unit 14. The secret code is, for example, a four-digit secret code. The worker operates the input button 17 to input the secret code. The main unit 12 verifies whether the input secret code is valid. Until the valid secret code is input, the main unit 12 withholds the output of an operation signal to turn on the power switch 10. On the other hand, when the valid secret code is input, the main unit 12 transmits an operation signal to turn on the power switch 10 to the first control unit 18 by wireless communication. Based on the received operation signal, the first control unit 18 mechanically operates the lever 20 of the power switch 10 by the actuator 23, the arm 22, and the cap 21 to switch the power switch 10. This turns on the power switch 10.

Then, the worker operates the operation control of the escalator 1 using the operation operation button 16 of the main unit 12. The worker performs an operation to start the drive unit 5, for example. The main unit 12 transmits an operation signal representing the input operation to the second control unit 19 by wireless communication. The second control unit 19 outputs a control signal to the control panel 9 based on the received operation signal. The control panel 9 operates based on the input control signal. In this example, the control panel 9 starts the drive unit 5. The worker then performs an operation to stop the drive unit 5, for example. The main unit 12 transmits an operation signal representing the input operation to the second control unit 19 by wireless communication. The second control unit 19 outputs a control signal to the control panel 9 based on the received operation signal. The control panel 9 operates based on the input control signal. In this example, the control panel 9 stops the drive unit 5.

Then, the worker operates the switch button 15 of the main unit 12 to turn off the power switch 10 of the escalator 1. The main unit 12 transmits an operation signal representing the input operation to the first control unit 18 via wireless communication. Based on the received operation signal, the first control unit 18 mechanically operates the lever 20 of the power switch 10 to switch the power switch 10. This turns off the power switch 10.

While controlling the operation of the escalator 1 in this way, workers carry out inspection work or repair work on the escalator 1. While the maintenance work is being carried out, the lid 4 of the upper machine room 3a cannot be opened.

In the maintenance process, the worker may obtain the information stored in the control panel 9 by the portable operation device 11. The information stored in the control panel 9 includes, for example, the failure history of the escalator 1. The information stored in the control panel 9 is read by the second control unit 19. The second control unit 19 may read the information stored in the control panel 9. The information stored in the control panel 9 may be, for example, identification information for identifying the escalator 1. The second control unit 19 outputs the read information to the main device 12 by wireless communication. The main device 12 stores the input information. The main device 12 may display the input information or the stored information on the display unit 14.

In the maintenance process, the worker may check the operation of the detection unit 8. The check of the operation of the detection unit 8 includes, for example, checking whether the detection signal is correctly output. In the check of operation, the detection unit 8 detects an event that has occurred in the escalator 1. The detection unit 8 may detect an event that has occurred in the escalator 1 in a simulated manner, for example, by a simulated signal. The detection unit 8 outputs a detection signal representing the detected event to the control panel 9. At this time, the second control unit 19 acquires the detection signal from the control panel 9. The second control unit 19 outputs the acquired information to the main unit 12 by wireless communication. The main unit 12 displays the input information on the display unit 14. The worker checks the operation of the detection unit 8 by the display on the display unit 14. The main unit 12 may emit a sound such as a buzzer sound based on the information of the input detection signal. The worker checks the operation of the detection unit 8 by the emitted sound. After the check of operation is performed in the main unit 12, the second control unit 19 may output a return signal to the control panel 9 to return the control panel 9 from the state in which the event was detected.

The communication range of the attachment device 13 is, for example, a range in which both the first control unit 18 and the second control unit 19 can wirelessly communicate with the main device 12. The communication range of the attachment device 13 is set, for example, so as not to include the lower boarding/alighting entrance 2b. The communication range of the attachment device 13 is set, for example, according to the size of the upper boarding/alighting entrance 2a. The communication range of the attachment device 13 is set, for example, so as to include the entire upper boarding/alighting entrance 2a. Alternatively, the communication range of the attachment device 13 may be set, for example, so as to fit within the left and right width of the upper boarding/alighting entrance 2a. Alternatively, when the escalator 1 to which the attachment device 13 is attached is adjacent to another escalator, the communication range of the attachment device 13 may be set according to the positional relationship with the adjacent escalator. For example, the communication range of the attachment device 13 is set to include the boarding/alighting entrance of the escalator 1 to which the attachment device 13 is provided, and not to include the boarding/alighting entrance of the adjacent escalator. The boarding/alighting entrance of the adjacent escalator may be either the upper boarding/alighting entrance or the lower boarding/alighting entrance. An adjacent escalator entrance is an example of a secondary entrance.

After the maintenance process, the worker performs the removal process.

Figure 6 shows an example of the removal process in the upper machine room 3a.

First, the worker opens the lid 4 of the upper machine room 3a.

Next, the worker removes the first control unit 18 from the power switch 10 in the upper machine room 3a. The worker removes the second control unit 19 from the control panel 9 in the upper machine room 3a. The worker takes out the removed first control unit 18 and second control unit 19 from the upper machine room 3a.

Then, the worker closes the lid 4 of the upper machine room 3a. The worker attaches the first control unit 18 and the second control unit 19 of the mounting device 13 to the main body device 12. The removal process is then completed.

As described above, the portable driving device 11 according to the first embodiment includes the attachment device 13 and the main body device 12. The attachment device 13 has a first control unit 18 and a second control unit 19. The first control unit 18 is attached to the power switch 10 in a machine room below the first boarding/alighting entrance of the passenger conveyor. The first control unit 18 switches the power switch 10 based on an input operation signal. The second control unit 19 is connected to a control panel 9 of the passenger conveyor in the machine room. The second control unit 19 outputs a control signal to the control panel 9 based on an input operation signal. The main body device 12 accepts an operation to control the passenger conveyor. The main body device 12 transmits an operation signal based on the accepted operation to the attachment device 13 via wireless communication.
The maintenance work method according to the first embodiment includes an installation step, a maintenance step, and a removal step. The installation step includes a procedure of opening the lid 4 of the machine room. The installation step includes a procedure of putting the first control unit 18 and the second control unit 19 into the machine room. The installation step includes a procedure of attaching the first control unit 18 to the power switch 10. The installation step includes a procedure of connecting the second control unit 19 to the control panel 9. The installation step includes a procedure of closing the lid 4 of the machine room after these procedures. The maintenance step is a step performed after the installation step. The maintenance step includes operation control of the passenger conveyor. The operation control of the passenger conveyor is performed by transmitting an operation signal based on the operation of the main device 12 to the installation device 13 by wireless communication. The removal step is a step performed after the maintenance step. The removal step includes a procedure of opening the lid 4 of the machine room. The removal step includes a procedure of removing the first control unit 18 from the power switch 10. The removal step includes a procedure of removing the second control unit 19 from the control panel 9. The removal process includes a procedure for removing the removed first control unit 18 and second control unit 19 from the machine chamber, and a procedure for closing the lid 4 of the machine chamber after the above procedures.
Also, during the maintenance process the machine room lid 4 cannot be opened.
Operation signals are communicated between the main unit 12 and the mounting unit 13 by wireless communication. Therefore, the operation control of the passenger conveyor is performed with the machine room lid 4 closed. This makes it difficult for the machine room lid 4 and openings to interfere with maintenance work. Also, since the power switch 10 is switched from the outside by the first control unit 18, it is not necessary to open and close the machine room lid 4 to power on the passenger conveyor. Therefore, it is not necessary to open and close the machine room lid 4 to control the operation of the passenger conveyor during the maintenance process. This makes it difficult for the work efficiency of the maintenance work to decrease.

Furthermore, the main device 12 requests the input of a secret code when transmitting an operation signal to turn on the power switch 10. The main device 12 suspends transmission of the operation signal until valid secret code is input.
When turning on the power switch 10, two steps of operation are required, namely, operating the switch button 15 and the like, and inputting a secret code, which prevents erroneous operation of turning on the power switch 10. The main device 12 does not need to require the input of a secret code for operations other than the operation of turning on the power switch 10. Since the input of a secret code is not required for all operations, the operation of controlling the operation of the passenger conveyor does not become excessively complicated.

In addition, the first control unit 18 mechanically operates the power switch 10 to switch it.
The power switch 10 is switched by an external mechanical operation. Therefore, there is no need to change the electrical circuit configuration of the control panel 9 or the power switch 10, etc., so the portable driving device 11 is easily applicable to existing passenger conveyors.

Furthermore, the attachment device 13 is detachably attached to the main body device 12 .
This makes the portable driving device 11 easier to transport.

Furthermore, the second control unit 19 acquires information stored in the control panel 9. The second control unit 19 transmits the acquired information to the main device 12 by wireless communication.
As a result, for example, when referring to information such as a failure history during maintenance work, it is not necessary to open and close the cover 4 of the machine room in order to obtain the information. This makes it possible to prevent a decrease in the efficiency of the maintenance work.

In addition, the second control unit 19 acquires a detection signal input from the detection unit 8 to the control panel 9. The detection unit 8 detects an event occurring on the passenger conveyor. The second control unit 19 transmits the acquired detection signal to the main device 12 by wireless communication.
This eliminates the need to open and close the cover 4 of the machine room in order to check the operation of the detection unit 8 including the safety switch, for example. This makes it possible to prevent a decrease in the efficiency of maintenance work.

In addition, the communication range of wireless communication in the attachment device 13 is set according to the size of the first boarding/alighting entrance.
In addition, when the first boarding/alighting entrance is adjacent to the second boarding/alighting entrance of another passenger conveyor, the communication range of the wireless communication in the mounting device 13 is set to include the first boarding/alighting entrance but not to include the second boarding/alighting entrance.
Since the communication range is limited according to the boarding/alighting gate, it is difficult for operation signals to interfere with each other. Also, when multiple passenger conveyors are installed, it is possible to prevent other passenger conveyors from being operated by mistake.

In addition, the main device 12 may transmit an operation signal to the attachment device 13 to turn off the power switch 10 when the time during which no operation is accepted exceeds a preset time.
This prevents inspection work, repair work, and the like from being performed on the passenger conveyor with the power switch 10 turned on. This prevents the passenger conveyor from being operated by mistake during inspection work, maintenance work, and the like.

In addition, in the passenger conveyor, the power switch 10 may be provided independently of the control panel 9. When the power switch 10 and the control panel 9 are provided in the lower machine room 3b, the mounting device 13 may be attached to the power switch 10 and the control panel 9 in the lower machine room 3b.

The passenger conveyor may also be a horizontal escalator 1, etc.

Next, an example of the hardware configuration of the portable driving device 11 will be described with reference to FIG.
FIG. 7 is a hardware configuration diagram of the main part of the portable driving device according to the first embodiment.

Each function of the portable driving device 11 may be realized by a processing circuit. The processing circuit includes at least one processor 200a and at least one memory 200b. The processing circuit may include at least one dedicated hardware 100 in addition to or in place of the processor 200a and memory 200b.

When the processing circuit includes a processor 200a and a memory 200b, each function of the portable driving device 11 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 200b. The processor 200a realizes each function of the portable driving device 11 by reading and executing the program stored in the memory 200b.

The processor 200a is also called a CPU (Central Processing Unit), processing device, arithmetic device, microprocessor, microcomputer, or DSP. The memory 200b is composed of non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM.

When the processing circuitry comprises dedicated hardware 100, the processing circuitry may be realized, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

Each function of the portable driving device 11 can be realized by a processing circuit. Alternatively, each function of the portable driving device 11 can be realized collectively by a processing circuit. Some of the functions of the portable driving device 11 may be realized by dedicated hardware 100, and other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the portable driving device 11 by dedicated hardware 100, software, firmware, or a combination of these.

Embodiment 2.
In the second embodiment, differences from the example disclosed in the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example disclosed in the first embodiment may be adopted.

Figure 8 is a configuration diagram of a portable driving device according to embodiment 2.

The mounting device 13 of the portable driving device 11 includes a relay unit 24. The relay unit 24 is equipped with a wireless communication function. The relay unit 24 directly receives an operation signal transmitted by wireless communication from the main device 12. The relay unit 24 relays the received operation signal by transmitting it to the first control unit 18 by wire or wirelessly. The relay unit 24 relays the received operation signal by transmitting it to the second control unit 19 by wire or wirelessly. The communication range of the mounting device 13 is, for example, a range in which the relay unit 24 can communicate wirelessly with the main device 12.

The relay part 24 is brought into the upper machine room 3a in the installation process. The relay part 24 is attached, for example, to the back surface of the lid 4 of the upper machine room 3a in the installation process. The relay part 24 is removed from the lid 4 of the upper machine room 3a in the removal process.

As described above, the mounting device 13 of the portable driving device 11 according to the second embodiment has the relay unit 24. The relay unit 24 relays communication between the first control unit 18 and the second control unit 19 and the main device 12 by performing wireless communication with the main device 12 in the machine room.
This makes it possible to set the communication range of the attachment device 13 by the arrangement of the relay unit 24, regardless of the arrangement of the control panel 9 and the power switch 10, etc. Therefore, interference of operation signals can be more effectively prevented.

The relay unit 24 may be removably attached to the main unit 12 when it is not attached to the passenger conveyor in the upper machine room 3a.

Embodiment 3.
In the third embodiment, differences from the examples disclosed in the first or second embodiment will be described in particular detail. For features not described in the third embodiment, any of the features of the examples disclosed in the first or second embodiment may be adopted.

Figure 9 is a configuration diagram of a portable driving device according to embodiment 3.

The mounting device 13 of the portable driving device 11 is equipped with a lid detection unit 25. The lid detection unit 25 is a part that detects the closed state of the lid 4 of the machine room into which the mounting device 13 is brought. The lid detection unit 25 may detect the closed state of the lid 4, for example, by measuring the gap between the edge of the manhole and the lid 4. The lid detection unit 25 may detect the closed state of the lid 4, for example, by measuring the contact pressure between the edge of the manhole and the lid 4. The lid detection unit 25 detects the closed state of the lid 4, for example, when the lid 4 is fully closed. In this example, the lid detection unit 25 is equipped with a wireless communication function. The lid detection unit 25 transmits a detection signal indicating the closed state directly to the main device 12 by wireless communication. The lid detection unit 25 outputs the detection signal to the first control unit 18 and the second control unit 19 by wire or wirelessly.

The main device 12 does not transmit an operation signal to the attachment device 13 when the closed state is not detected by the lid detection unit 25. For example, the main device 12 suspends transmission of an operation signal to the attachment device 13 until a detection signal indicating the closed state is received from the lid detection unit 25. Alternatively, the main device 12 may ignore an operation that outputs an operation signal when a detection signal indicating the closed state is not received from the lid detection unit 25.

The attachment device 13 does not accept an operation signal from the main device 12 when the lid detection unit 25 does not detect a closed state. For example, the first control unit 18 and the second control unit 19 ignore the input operation signal until they receive a detection signal indicating a closed state from the lid detection unit 25.

As described above, the attachment device 13 of the portable driving device 11 according to the third embodiment has the lid detection unit 25. The lid detection unit 25 detects the closed state of the lid 4 of the machine room. The attachment device 13 does not accept an operation signal from the main device 12 when the lid detection unit 25 does not detect the closed state. Furthermore, the main device 12 does not transmit an operation signal to the attachment device 13 when the lid detection unit 25 does not detect the closed state.
As a result, the operation control of the passenger conveyor is performed after confirming that the cover 4 of the machine room is closed. Therefore, the cover 4 of the machine room and the like are less likely to interfere with maintenance work.

The lid detection unit 25 may transmit the detection signal to the main device 12 through the relay unit 24. The lid detection unit 25 may transmit the detection signal to the main device 12 through either the first control unit 18 or the second control unit 19.
