(Outline of ventilation alarm 10)

FIG. 1(A) is a schematic configuration diagram of a ventilation alarm 10 according to the present embodiment, and FIG. 1(B) is a front view of a kitchen 12 showing the installation state of the ventilation alarm 10.

As shown in FIG. 1(A), the ventilation alarm 10 is covered with a casing 14, and the front side is used to introduce atmospheric air into a gas detection unit (not shown) housed inside the casing 14. A first opening 16 and a second opening 18 for outputting audio from a speaker (not shown) housed inside the housing 14 to the outside are provided.

Further, below the first opening 16 and the second opening 18, a ventilation lamp 20, a notification lamp 22, and a switch 24 are provided.

Further, a contact sticker 26 is attached to the lower front of the housing 14.

The gas detection unit detects CO contained in the atmosphere introduced from the first opening 16. When the gas detection section detects CO, the speaker sounds an alarm sound, and the sound is output from the second opening 18.

The ventilation lamp 20 is normally off, but blinks when the gas detection unit detects CO. The notification lamp 22 is normally off, but blinks when there is an equipment abnormality, the battery runs out, or it is time to replace the battery.

The switch 24 is operated when inspecting the operation and stopping the alarm sound.

The contact information sticker 26 includes contact information in the event of an abnormality, a telephone number, and a replacement deadline for the ventilation alarm 10.

As shown in FIG. 1(B), the ventilation alarm 10 is mainly installed in a kitchen 12 of a restaurant, etc., and the position where it can fully function as the ventilation alarm 10 is determined. .

That is, as an example, CO can be detected quickly and reliably by being attached to a wall within a horizontal distance of 8 m from the combustion equipment 28 of the kitchen 12 and within a range of 170 cm±20 cm from the floor surface 30. Although not shown here, the distance from the ventilation opening (not shown) installed in the kitchen 12 is also an important factor.

Further, the ventilation alarm 10 has a lifespan as a product, for example, 6 years.

(Ventilation alarm related work support system)

The ventilation alarm 10 described above is managed by a professional who has gas knowledge. Specifically, the management company goes to the site, performs new installations, processes when the product life has expired, and performs regular or irregular inspections, and manages work history. are doing.

By the way, administrative work related to the new installation, expiration process, and inspection process of the ventilation alarm 10 for commercial equipment such as the combustion equipment 28 of the kitchen 12 (see FIG. 1(B)) described above is not performed in general. Compared to the administrative work related to the installation and inspection of gas appliances, there are many documents to be created on-site to keep a work history, which places a heavy burden on the on-site workers.

Therefore, in this embodiment, a ventilation alarm-related work support system was constructed to support work related to document creation by field workers.

FIG. 2(A) is an overall configuration diagram of the ventilation alarm-related work support system according to the present embodiment.

A business management server 52 is connected to the network 50 and functions as a database for ventilation alarm related work.

A wireless communication device 54 is connected to the network 50 . Thereby, the business management server 52 is capable of communicating with a plurality of communication terminal devices 56 carried by workers heading to the site to perform ventilation alarm-related work.

The communication terminal device 56 includes a microcomputer 68 that includes a CPU 58, a RAM 60, a ROM 62, an input/output section (I/O) 64, and a bus 66 such as a data bus or a control bus that connects these.

A communication I/F 70 is connected to the I/O 64, and communication is performed with the wireless communication device 54 described above.

Further, a photographing device 71, an internal memory 72, and an IC memory slot 74 are connected to the I/O 64. An IC memory 76 such as a USB or an SD card can be inserted into and removed from the IC memory slot 74 .

A ventilation alarm related work support application program (hereinafter referred to as support application) is installed in the internal memory 72 of the communication terminal device 56. When the support application is started, the communication terminal device 56 cooperates with the work management server 52 and displays necessary information on the monitor based on the work status to support the worker.

The support app supports the following processes as work support.

(Support 1) Obtain personal information and work type information through preliminary processing.

(Support 2) In on-site processing, one set of information handling after the work is completed includes (a) input operation to the communication terminal device 56, (b) uploading to the business management server 52, and (c) deleting information. and describe what to do if the upload fails (such as leaving it on the communication terminal device 56).

(Support 3) During on-site work (new installation, updated installation), an image of the installation position is photographed using the photographing device 71 installed in the communication terminal device 56, and is stored in the management server in association with other information. put. Note that the photograph is not limited to the photographing device 71 of the communication terminal device 56, and may be taken with a digital camera or the like and transferred to the communication terminal device 56.

(Support 4) The image information transmitted from the communication terminal device 56 and stored in the business management server 52 is used to confirm the installation position of the ventilation alarm the next time you visit the same site.

(Support 5) When visiting the same site, the ventilation alarm 10 is photographed, and the photographed image information is automatically compared with the image information stored in the business management server 52 to search for differences and output. For example, differences with respect to installation standards (height from the floor 30, distance from the combustion equipment 28, etc.), differences in appearance, etc.

The operation of this embodiment will be explained below according to the flowcharts of FIGS. 3 to 8.

(pre-processing)

FIG. 3 is a control flowchart showing a pre-processing routine executed by the CPU 58 of the communication terminal device 56 based on the support application.

At step 100, a login process is executed using the ID and password assigned to the worker, and then the process moves to step 102, where the work management server 52 is accessed and the work list for the day is read. The work list includes, for example, customer information, and the work to be processed in one day is displayed in a table format. Note that the route and parking information for each work site can be checked in advance by using a route search function, a parking lot recognition function, etc. that are registered as separate application programs.

In the next step 104, a work list is displayed on the display section of the communication terminal device 56, and this routine ends.

The work processing items displayed in the work list are new processing (new installation work), expiration processing (expiration replacement work), and inspection processing (inspection work). They will head to the work site in the order they searched using the search function.

(on-site processing)

FIG. 4 is a control flowchart showing a field processing main routine executed by the CPU 58 of the communication terminal device 56 based on the support application.

In step 110, the work list already read from the business management server 52 in step 102 of FIG. 3 is displayed, and a work target is selected.

In the next step 112, the types A to C of the selected work object are determined.

That is, when the ventilation alarm 10 is newly installed, the process moves to step 114 and new processing (A) is executed (see FIG. 5).

Furthermore, if the ventilation alarm 10 that has already been installed has reached its expiry date (6 years), the process moves to step 116 and executes the expiration process (B) that provides replacement guidance (including replacement work) (see Figure 6). ).

Furthermore, in the case of inspection work of the ventilation alarm 10 and surrounding business equipment and piping, which is carried out regularly or irregularly, the process moves to step 118 and the inspection process (C) is executed (see FIG. 7).

(Subroutine of new process “Step 114 in Figure 4”)

FIG. 5 is a control flowchart showing the detailed flow of the new processing subroutine in step 114 of FIG. 4, which is executed when the installation of the ventilation alarm 10 is completed.

In step 150, customer information is read and displayed. The customer information has already been registered and stored in the communication terminal device 56 in the pre-processing of FIG. 3, and in this step 150, it is read from the internal memory 72 of the communication terminal device 56 and displayed on the display unit.

In the next step 152, identification information of the ventilation alarm 10 is input. The identification information of the ventilation alarm 10 is often given as a bar code or QR code (registered trademark) to a part of the contact sticker 26 (see FIG. 1(A)), and the identification information of the communication terminal device 56 is Identification information can be captured using a code reading application. Note that the numbers provided with the barcode or QR code (registered trademark) may be manually input.

In the next step 154, the photographing device 71 of the communication terminal device 56 photographs the ventilation alarm 10 and objects around it. Note that in the case of the communication terminal device 56 without the photographing device 71, the photograph may be separately taken with a digital camera or the like and imported into the communication terminal 56 via wireless communication, an IC memory, or the like.

In the next step 156, the work-related information is displayed in a list on the display unit of the communication terminal device 56 in a state in which the work-related information is associated with each other. The work-related information includes customer information, identification information of the ventilation alarm 10, photographed images, and work information (progress according to the time axis when performing the work, status after the work is completed, etc.) The history of installing the alarm 10 and the state of the ventilation alarm 10 after it has been installed (such as whether it is installed in the correct position) can be visualized and confirmed on the display.

In the next step 158, electronic signature processing is executed. In this step 160, it is determined whether or not the customer has input a valid electronic signature, but before that, the worker verbally informs the customer that the installation of the ventilation alarm 10 is complete and various precautions. , and then request electronic signatures from customers.

When the input of a valid electronic signature is completed in step 158, the process moves to step 160. In step 160, it is determined whether or not there is an operation indicating the completion of the task from the operation screen of the support application of the communication terminal device 56, and the process waits until there is an operation to complete the task.

If an affirmative determination is made in step 160, that is, if there is a task completion operation, the process moves to step 162 to perform network connection processing with the business management server 52, and then, if the connection is established in step 164 (affirmative determination), The process moves to step 166 and information transmission processing to the business management server 52 is executed.

In the process of transmitting information to the business management server, first, in step 166, work related information is transmitted to the business management server 52. The next step 168 is to determine whether the transmission is complete. If a negative determination is made in step 168, the process proceeds to step 170, where it is determined whether an error has occurred regarding transmission. If a negative determination is made in this step 170, the process returns to step 168, and steps 168 and 170 are repeated until a positive determination is made in either step 168 or step 170.

Here, if an affirmative determination is made in step 168, it is determined that the transmission of the work-related information to the business management server 52 is completed, and the process proceeds to step 172, in which the work-related information stored in the communication terminal device 56 is transmitted. It is deleted and the process moves to step 176. As a result, no work-related information remains in the communication terminal device 56, so that problems such as information leakage do not occur.

On the other hand, if an affirmative determination is made in step 170, it is determined that a certain period of time has elapsed during which work-related information cannot be transmitted to the business management server 52, and a communication error has occurred, and the process proceeds to step 174. The work-related information is left and the process moves to step 176. As a result, the work-related information is maintained in the internal memory 72 of the communication terminal device 56, so that loss of information can be prevented.

In step 176, the status of the work-related information (deleted or maintained) is stored, and the routine ends.

For example, when launching the next support application, if the previous work-related information is maintained, an alert is issued and an attempt is made to communicate and send information to the work management server 52. Note that it is preferable that the work-related information is ultimately transmitted to the work management server 52 by wired communication or the like at the end of the working day.

(Subroutine of expiration process “Step 116 in Figure 4”)

FIG. 6 is a control flowchart showing the detailed flow of the expiration processing subroutine in step 116 of FIG. 4, which is executed when the ventilation alarm 10 reaches the end of its life.

In step 200, customer information is read and displayed. The customer information has already been registered and stored in the communication terminal device 56 in the pre-processing of FIG. 3, and in this step 200, it is read from the internal memory 72 of the communication terminal device 56 and displayed on the display unit.

In the next step 202, it is determined whether the customer has approved the replacement of the existing ventilation alarm 10 that has reached the end of its service life with a new ventilation alarm 10. However, between step 200 and step 202, the customer There is verbal negotiation to persuade the existing ventilation alarm 10 to be replaced with a new ventilation alarm 10, and for example, the result of the negotiation is displayed on the support application running on the communication terminal device 56. Input by operating the screen replacement necessity key.

In step 202, if the operation of the replacement necessity key determines that replacement is not necessary, it is determined that the customer has no intention of installing a new ventilation alarm 10, and this routine ends.

Further, in step 202, if the operation of the replacement necessity key determines that replacement is necessary, the process proceeds to step 152A after the replacement operation.

Hereinafter, since the processing after step 152A is the same as the processing from step 152 to step 176 in FIG. 5, "A" is added to the end of the step number to clarify the contrast.

In the next step 152A, identification information of the ventilation alarm 10 is input. The identification information of the ventilation alarm 10 is often given as a bar code or QR code (registered trademark) to a part of the contact sticker 26 (see FIG. 1(A)), and the identification information of the communication terminal device 56 is Identification information can be captured using a code reading application. Note that the numbers provided with the barcode or QR code (registered trademark) may be manually input. Further, if the communication terminal device 56 is equipped with an OCR function, the identification information may be acquired by OCR processing.

In the next step 154A, the photographing device 71 of the communication terminal device 56 photographs the ventilation alarm 10 and objects around it. Note that in the case of the communication terminal device 56 without the photographing device 71, the photograph may be taken with a separate digital camera or the like and imported into the communication terminal device 56 via wireless communication, an IC memory, or the like.

In the next step 156A, the work-related information is displayed in a list on the display unit of the communication terminal device 56 in a state where it is associated with each other. The work-related information includes customer information, identification information of the ventilation alarm 10, and photographed images, and includes information on how the ventilation alarm 10 was newly installed and the state of the ventilation alarm 10 after installation (whether it is in the correct position). It is possible to visually check on the display unit whether the device is attached or not.

In the next step 158A, electronic signature processing is executed. In this step 160A, it is determined whether or not a valid electronic signature has been input by the customer, but before that, the worker verbally completes the installation of the ventilation alarm 10 and notifies the customer of various precautions, etc. After making the information known, customers will be required to provide electronic signatures.

When input of a valid electronic signature is completed in step 158A, the process moves to step 160A. In step 160A, it is determined whether or not there is an operation indicating the completion of the task from the operation screen of the support application of the communication terminal device 56, and the process waits until there is an operation to complete the task.

If a positive determination is made in step 160A, that is, if there is a task completion operation, the process moves to step 162A to perform network connection processing with the business management server 52, and then, if the connection is established in step 164A (affirmative determination), The process moves to step 166A and information transmission processing to the business management server 52 is executed.

In the process of transmitting information to the business management server, work-related information is first transmitted to the business management server 52 in step 166A. In the next step 168A, it is determined whether the transmission is complete. If a negative determination is made in step 168A, the process moves to step 170A, and it is determined whether or not an error has occurred regarding transmission. If a negative determination is made in this step 170A, the process returns to step 168A, and steps 168A and 170A are repeated until a positive determination is made in either step 168A or step 170A.

Here, if an affirmative determination is made in step 168A, it is determined that the transmission of the work-related information to the business management server 52 is completed, and the process proceeds to step 172A, in which the work-related information stored in the communication terminal device 56 is transmitted. It is deleted and the process moves to step 176A. As a result, no work-related information remains in the communication terminal device 56, so that problems such as information leakage do not occur.

On the other hand, if an affirmative determination is made in step 170A, it is determined that a certain period of time has elapsed during which work-related information cannot be transmitted to the business management server 52, a communication error has occurred, and the process moves to step 174A to send the work-related information to the communication terminal device 56. The work-related information is left and the process moves to step 176A. As a result, the work-related information is maintained in the internal memory 72 of the communication terminal device 56, so that loss of information can be prevented.

In step 176A, the status of the work-related information (deleted or maintained) is stored, and the routine ends.

For example, when launching the next support application, if the previous work-related information is maintained, an alert is issued and an attempt is made to communicate and send information to the work management server 52. Note that it is preferable that the work-related information is ultimately transmitted to the work management server 52 by wired communication or the like at the end of the working day.

(Subroutine of inspection process “Step 118 in Figure 4”)

FIG. 7 is a control flowchart showing the detailed flow of the inspection process subroutine in step 118 of FIG. 4, which is executed when inspecting the ventilation alarm 10.

It is preferable that the inspection process is performed periodically after the installation of the ventilation alarm 10, and also during other work opportunities (for example, regular facility safety patrols and special patrols). It should be noted that, unlike the above-mentioned regular safety patrols for gas equipment, etc., special patrols refer to patrols that occur irregularly and are relatively urgent matters.

In step 300, the ringing history is checked. There are two types of confirmation means for checking the ringing history: acquisition by wireless communication and acquisition by manual operation.

For acquisition through wireless communication, for example, by activating a support application on the communication terminal device 56, wireless communication using Wi-Fi or Bluetooth (registered trademark) can be established.

According to this wireless communication, it is possible to obtain a list of ringing times, locations, etc. from the initial stage of installation.

On the other hand, in manual acquisition, by operating the switch 24 shown in FIG. 1(A), the presence or absence of ringing within a certain period of time in the past is notified by the lighting state of the notification lamp 22.

In the next step 302, it is determined whether or not there is a sounding history by checking with any of the confirmation means described above, and if it is determined that there is "no sounding", it is determined that there is no abnormality in the ventilation alarm 10, This routine ends.

If it is determined in step 302 that there is a sound, there is an abnormality in the ventilation alarm 10, so verbally explain to the customer the cause of the sound and the need for investigation, and obtain permission for the inspection. Negotiate for the purpose.

If inspection permission is not obtained after negotiation, subsequent processing is canceled and this routine ends in the same way as when there is no ringing history.

If permission for inspection is obtained after negotiation, the inspection will be carried out, but for example, if the inspection is to be carried out during another work period, preparations for detailed inspection and repair work of the ventilation alarm 10 have not been made. A detailed inspection will be conducted at a later date. For this reason, in step 304, the ventilation alarm 10 is inspected, and information such as the frequency of ringing, the date and time of visit, and whether advance notice of the visit is required is entered.Then, the process proceeds to step 306, and the input information is sent to the business management server 52. do.

In the next step 308, work-related information at the time of installation of the ventilation alarm 10 (new processing) is acquired from the business management server 52, and then the process moves to step 310, where the acquired work-related information is transferred to the communication terminal device 56. Display.

The worker visually determines the displayed work-related information and the current situation. For example, the customer information, industry type (situation of the kitchen 12 (see FIG. 1B)), installation position, etc. at the time of the previous installation of the ventilation alarm 10 are determined.

In step 312, if there is a difference from the previous work-related information displayed on the communication terminal device 56, the work-related information is edited (deleted, modified, updated, etc.), and the process proceeds to step 314, where the editing is performed. The contents are sent to the business management server 52, and this routine ends.

As described above, in the inspection process, the history of the sounding of the ventilation alarm 10 can be confirmed, and if there is sounding, the need for detailed inspection is explained, and the current status (customer, industry, ventilation alarm (installation position, etc.) is different from the previous work-related information, by editing the work-related information, new work-related information can be created for each inspection.

As described above, in this embodiment, when a worker performs work related to the ventilation alarm 10, a support application that can communicate with the work management server 52 via the network is installed on the communication terminal device 56. , pre-work pre-processing, and work site processing (new processing, expiration processing, inspection processing) are collectively managed by the business management server 52.

This allows the communication terminal device 5 to perform complicated manual input work such as entering information into important documents related to work using paper media, which is separate from the actual work (installation work, replacement work, and inspection work of the ventilation alarm 10). The touch operation based on the display screen can improve the work efficiency of manual input operations related to the ventilation alarm 10.

Further, in the present embodiment, in the inspection process, the installation state (position, appearance, etc.) of the ventilation alarm 10 is determined using a photographed image. Note that in this embodiment, even when newly installed in new processing and replaced in expiration processing, the ventilation alarm 10 and objects around it are photographed after installation and replacement, and the information is stored in the business management server 52. The captured images are stored.

FIG. 8 is a control flowchart specialized for understanding the usage status of the ventilation alarm 10 using images, which is executed during the inspection process.

First, in step 350, the photographing device 71 of the communication terminal device 56 photographs the ventilation alarm 10 and objects around it. Note that in the case of the communication terminal device 56 without the photographing device 71, the photograph may be taken with a separate digital camera or the like and imported into the communication terminal device 56 via wireless communication, an IC memory, or the like.

In the next step 352, the external appearance is analyzed based on the photographed image of the ventilation alarm 10. Specifically, we analyze evidence of improper use, including adhesion of water or oil, damage, and evidence of modification.

In the next step 354, it is determined from the analysis result of the external appearance of the ventilation alarm 10 whether or not there is improper use, and the process moves to step 356.

In step 356, based on the result of step 354, the presence or absence of improper use is displayed on the display section of the communication terminal device 56, and the process proceeds to step 358. It is preferable to display the reason when there is an unsuitability (for example, there is a large amount of oil, which may interfere with CO detection, or there is a possibility that water droplets may adhere and cause an electrical leakage. Yes, etc.)

Here, the worker (inspector), for example, while showing the display on the communication terminal device 56 to the customer, if the ventilation alarm 10 is found to be inappropriate, it is necessary to verbally replace the ventilation alarm 10. Explain this and negotiate an exchange. If there is no improper use, no verbal explanation is required.

In step 358, the image of the ventilation alarm 10 when it was installed last time is read from the business management server 52, and then the process moves to step 360, where the installation position is compared based on the image information of the old and new ventilation alarm 10. , the process moves to step 362.

In step 362, whether or not there is a mismatch between the mounting positions of the old and new ventilation alarms 10 is displayed on the display section of the communication terminal device 56, and the process moves to step 364.

Here, the worker (inspector) inspects the suitability of the mounting position of the ventilation alarm 10 at the site. Even if the position is different from the previous time, there is no problem as long as it is within the tolerance (reference position) shown in FIG. 1(B).

On the other hand, if it has deviated from the reference position, the operator (inspector) explains how to change the installation position of the ventilation alarm 10 while showing the display on the communication terminal device 56 to the customer, for example.

That is, the operator (inspector) looks at the display indicating whether there is a discrepancy in step 362, and if it is necessary to change the installation position of the ventilation alarm 10 and the customer has given permission for the installation position, the operator (inspector) changes the communication terminal. A key operation is performed on the device 56 indicating that replacement is necessary, and if the ventilation alarm 10 is installed at the reference position, a key operation is performed on the communication terminal device 56 indicating that replacement is not necessary.

In step 364, it is determined whether there is an input as to whether or not the installation position of the ventilation alarm 10 needs to be changed. If a negative determination is made in step 364, there is no need to change the mounting position of the ventilation alarm 10, and this routine ends.

On the other hand, if an affirmative determination is made in step 364, the change in the mounting position of the ventilation alarm 10 is executed, so the process moves to step 366, and a key operation indicating that the change in the mounting position of the ventilation alarm 10 has been completed is performed. Determine whether it happened or not.

If an affirmative determination is made in step 366, the process proceeds to step 368, where an image of the ventilation alarm 10 at the final installation position is photographed, and then, the process proceeds to step 370, where the photographed image is associated with work-related information. , to the business management server 52, and this routine ends.

As explained above, in the inspection process based on image judgment according to the present embodiment, based on the photographed image, adhesion of water or oil, damage, evidence of improper use, evidence of modification, etc. are analyzed.

Thereby, a more reliable result can be obtained than when an inspector visually checks the result, and it becomes easier to persuade a customer to replace the ventilation alarm 10, for example.

In addition, by comparing the image of the ventilation alarm 10 when it was installed last time with the image at the time of inspection, the displacement of the installation position can be visualized and shown to the customer, and the change in the installation position of the ventilation alarm 10 can be visualized. It becomes easier to persuade customers.

In this embodiment, the external appearance was analyzed and the old and new positions were compared using a still image, but a moving image may also be used.
