There is a landing 9 and the like in the pit 5 and others including the buffer 6 and the counter weight 8 and the like. The work content and measurement items are determined in advance by these work locations and work target devices, and these are performed using the maintenance work support device.

FIG. 1 is a block diagram showing a maintenance work support device according to an embodiment of the present invention. A portable terminal device, which is a maintenance work support device, includes a microphone 10 for converting a pronounced voice into an electric signal, and a voice recognition device connected to the microphone 10 for coding a voice signal for each single sound and editing it into a coded word. Unit 11, a processing unit 12 connected to the speech recognition unit 11, a text table 13 referred to by the processing unit 12, a storage unit 14 and a dictionary switching unit 15 connected to the processing unit 12, a speech recognition unit The common dictionary 16 is connected to the dictionary 11 and a machine dictionary 16a, a tower dictionary 16b, and a pit dictionary 16c, which are item dictionaries connected to the dictionary switching unit 15, respectively.

The common dictionary 16 stores coded words such as numerical values of 0 to 9 and decimal points, in addition to a machine room 1, a tower 2, a pit 5, and the like, which are maintenance work locations of an elevator. The machine room dictionary 16a stores coded words such as measurement item names such as voltage and current in addition to device names such as the hoisting machine 3 and the electric motor installed in the machine room 4, and In the tower dictionary 16b, in addition to the names of devices such as hatch doors, that is, landing doors and door switches provided on the doors, which are work sites to be performed from inside the tower 2, an open state and a gap state of doors and door switches are collectively referred to. Coded words such as inspection items and measurement item names such as gaps and gaps are stored. The pit dictionary 16c includes, in addition to the names of the buffers 6 and main rails installed in the pits 5, the clearance between the lower end of the counterweight 8 and the buffer 6 when the car 1 stops on the top floor. Coded words such as measurement item names are stored.

In the above-mentioned wording table 13, a recognition wording column 13a such as a machine room, an electric motor, and an electric current corresponds to a classification column 13b for classifying whether these are parts or items. Maintenance work locations such as machine rooms, towers, pits, etc., registered in the common dictionary 16 are classified fields 13b.
The items are classified in the column 13b, and the other device names, inspection item names, and measurement item names in the recognition wording column 13a are classified. The storage unit 14 includes an item name column 14a for storing voltage, current, and the like, and a measured value column 14b for storing measured values and inspection results corresponding to the items.

Next, the operation of the maintenance work support apparatus and the maintenance work support method will be described with reference to the flowchart shown in FIG. For example, when measuring the input voltage of the electric motor 3 in the machine room 4, a maintenance worker (not shown)
At 1, the user speaks “machine room” toward the microphone 10. As a result, the microphone 10 transmits a voice signal to the voice recognition unit 11, and in step S2, the voice recognition unit 11 converts the “machine room” into a code and outputs the “machine room” from the text stored in the common dictionary 16. Is transmitted to the processing unit 12. The processing unit 12 stores the “machine room” in the text table 1 in step S3.
In step S4, it is determined whether or not the corresponding section 13b is a part. here,
Since “machine room” is a part, the process proceeds to step S5, where the processing unit 12 transmits an instruction to switch to the machine room dictionary 16a to the dictionary switching unit 15 in step S5, and the speech recognition unit 2 uses the dictionary as the machine room dictionary 16a. The work item of the machine room can be registered, and the process returns to step S1 to wait for the next voice input.

Next, when the maintenance worker utters "motor" toward the microphone 10 in step S1, the microphone 10 transmits this voice signal to the voice recognition unit 11, and the flow proceeds to step S2.
The voice recognition unit 11 converts the “motor” into a code, refers to the words stored in the common dictionary 16 and the machine room dictionary 16a, checks the “motor” in the machine room dictionary 16a, and processes the message. 12 is transmitted. Then, the processing unit 12 sets “Electric motor” to the recognition text field 13 of the text table 13 in step S3.
a, and the corresponding division column 13 in step S4
It is searched whether or not b is a site. Here, since the item is an item, it is detected in step S6.
Go to 7. In step S7, "motor" is stored in the item name column 14a of the storage unit 14, and the process returns to step S1 to wait for the next voice input.

Thereafter, when the maintenance worker utters "voltage" toward the microphone 10 in step S1, the microphone 10 transmits a voice signal to the voice recognition unit 11, and the voice recognition unit 11 outputs the "voltage" in step S2. Convert to code and common dictionary 1
6 and the words stored in the machine room dictionary 16a, the “voltage” of the machine room dictionary 16a is checked, and the processing unit 12
Send to Then, the processing unit 12 performs a recognition process on the recognition word column 13a of the word table 13 in step S3, and determines whether or not the region is a part by referring to the classification column 13b in step S4. Since "voltage" in the recognition wording column 13a is an item, if it is determined in step S6, the process proceeds to step S7, and the storage unit 14
Is stored in the item name column 14a, and the process returns to step S1 to wait for the next voice input.

Next, when the maintenance worker utters "2", "0" and "0" toward the microphone 10 in step S1, the microphone 10 transmits a voice signal to the voice recognition unit 11, and the voice recognition unit 11 In step S2, "2", "0", and "0" are converted to codes, and "2" and "0" of the common dictionary 16 are referenced by referring to the words stored in the common dictionary 16 and the machine room dictionary 16a.
After confirming “0”, it transmits to the processing unit 12. Processing unit 12
Is the recognition text field 13 of the text table 13 in step S3.
In step S4, it is determined whether or not the classification column 13b corresponding to the recognition wording column 13a is a part. Here, since it is not a part, the process proceeds to step S6, where it is determined whether the item is an item. Since it is not an item, the process proceeds to step S8. In this step S8, it is determined whether or not it is a numeral. Since it is a numeral, the process proceeds to step S9, and "200" is stored in the measured value column 14b of the storage unit 14 in step S9. On the other hand, if the processing unit 12 cannot recognize anything in step S8,
Proceeding to step S10, a notification to the effect that recognition was not possible is given to the maintenance worker by voice or display, and the process returns to step S1. In such a series of operations of steps S1 to S9,
The measured value of the input voltage of the motor 3 is stored in the storage unit 14 of the portable terminal device.
Is stored in

Here, the numerical value and the decimal point are stored in the common dictionary 16.
Because there is no significant difference in the number of words from other dictionaries, the recognition rate does not decrease. In addition, since the numerical input for the maintenance work of the elevator can be performed in the common dictionary 16, the numerical input by voice can be performed quickly and accurately.

When the measurement of other devices in the machine room 4 is to be continued, similarly, the device name, the inspection item name, the measurement item name, and the numerical value indicating the item are successively spoken to store the measured value of each item. It can be recorded in the unit 14.

Next, when the maintenance worker moves to the inside of the tower 2 and continues his work, he speaks "inside the tower" toward the microphone 10 in step S1. Is transmitted to the voice recognition unit 11 at step S2.
Then, “inside the tower” is converted into a code, and “inside the tower” of the common dictionary 16 is confirmed by referring to the words stored in the common dictionary 16 and the machine room dictionary 16a, and transmitted to the processing unit 12. Then, the processing unit 12 recognizes the recognized wording column 13a of the wording table 13 in step S3, and determines in step S4 whether or not the corresponding division column 13b is a part. Dictionary switching unit 1 in S5
5, an instruction to switch to the tower dictionary 16b is transmitted, the work dictionary of the machine room can be registered in the speech recognition unit 2 as the tower dictionary 16b, and voice input can be performed in the same manner as the above-described processing. .

Similarly, when another part is measured, a dictionary registered in the wording table 4 such as the pit 23 is uttered, so that the dictionary of the voice recognition unit 2 is switched in steps S4 and S5, and The measurement of the site becomes possible.

As described above, the maintenance work support apparatus comprises the common dictionary 16 and the machine room dictionary 1 which can be switched depending on the work location.
By using item dictionaries such as 6a, the tower dictionary 16b, and the pit dictionary 16c, the number of words registered in each dictionary used at the work location can be specified and the number can be reduced. It is possible to improve the recognition and reduce malfunctions in recognition. In addition, since records can be input in the order of work performed by the maintenance worker, it is expected that the work time will be shortened by getting used to the operation of the maintenance work support device.

In the above-described embodiment, the input operation of the measured value has been described. However, the input of the result of whether or not the operation has been performed, the input of the replacement part, the input of the replacement part, and the like can be similarly performed. Also, the common dictionary 16, the machine room dictionary 16a,
Although the item dictionaries such as the tower dictionary 16b and the pit dictionary 16c and the words in the wording table 13 have been described as being stored in advance, the same effect can be obtained even if the words can be replaced according to the equipment and its type. In addition, each dictionary
Although each section is moved according to the maintenance work, the section may be used differently.
