Description

The present invention relates to a management system that manages information terminals.

Currently, information terminals such as information code reading terminals that optically read information codes are used for various purposes in various environments. By the way, in such an information terminal, if it breaks down during use, the read data read up to that point is lost, and there is a possibility that a loss such as redoing business may occur. Therefore, for example, as in the image management system disclosed in Patent Document 1 below, by transmitting the patient number and image data acquired by the image pickup device to the information processing device, even when the image pickup device breaks down or the like. It facilitates data recovery without losing the data acquired so far.

Japanese Unexamined Patent Publication No. 2015-219649

By the way, when an operation abnormality or a failure occurs in the information terminal itself, it is generally necessary for the user to make an inquiry to the administrator because he / she does not know how to deal with it, and it often takes time to recover the information terminal. On the other hand, even if the administrator asks the user about the usage status at the time of failure in order to confirm the cause of the failure, the information heard from the user is often ambiguous and useful information. Is unlikely to be obtained.

With regard to such problems, in a configuration in which information such as operation logs is sequentially saved in a flash ROM or the like on an information terminal, the manufacturer can analyze the saved operation logs or the like in the event of a failure and investigate the cause. However, the user cannot confirm the operation log or the like, and even if it can be confirmed, the cause cannot be investigated. In particular, in a configuration in which information such as an operation log is saved in a flash ROM or the like, there is a limit to the amount of data that can be saved, and even analysis of the operation log or the like cannot be performed in the case of a failure or the like in which information cannot be retrieved from the flash ROM or the like in the first place. There can be a situation like that.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a configuration capable of easily confirming the state of an information terminal to be managed.

In order to achieve the above object, the invention according to claim 1 of the claims is

The reference numerals in the parentheses indicate the correspondence with the specific means described in the embodiments described later.

In the invention of claim 1, in the information terminal, terminal data relating to the state of the information terminal is acquired by the acquisition unit, and the acquired terminal data is associated with specific information and periodically transmitted to the server by the transmission unit. Will be done. Further, in the server, the data received from the information terminal is stored in the terminal data storage unit. Then, in the server, in response to a request accompanied by the specific information, the analysis unit analyzes the state of the information terminal specified from the specific information based on the terminal data stored in the terminal data storage unit in association with the specific information. Then, this analysis result is notified to the requester by the notification unit.

As a result, when the information terminal fails, the server is requested to accompany the specific information that identifies the failed information terminal, and the analysis result of analyzing the state of the information terminal is notified. , The state of the information terminal to be managed can be easily confirmed based on the analysis result. In particular, since the server periodically receives the terminal data acquired by the acquisition unit, for example, even if the information terminal does not operate, the terminal data that was periodically received until immediately before the failure. Can be analyzed, so that the cause of the failure can be easily investigated.
In particular, the information terminal is an information code reading terminal that receives the reflected light from the one-dimensional code through the dustproof plate at the light receiving unit and optically reads the one-dimensional code based on the received light waveform, and is dustproof. A value corresponding to the height of the received light waveform when reading fails due to deterioration of the plate is stored in the threshold storage unit as a first threshold value. Then, in the information terminal, if the height of the received light waveform continues to be equal to or lower than the first threshold value when the reflected light is received, the first notification information indicating that the dustproof plate needs to be replaced is transmitted by the transmission unit. It is included in the terminal data transmitted by. Then, in the server, when the terminal data analyzed by the analysis unit includes the first notification information, the notification unit notifies the requester that the dustproof plate needs to be replaced.
As a result, reading by the information terminal is not successful. Therefore, when the server is requested to accompany the specific information of the information terminal, if the information terminal fails to read due to deterioration of the dustproof plate, the reading fails. Since the terminal data analyzed by the analysis unit of the server includes the first notification information, the requester is notified that the dustproof plate needs to be replaced. Therefore, the user or the like of the information terminal who has made the above request can easily know the cause of the reading failure and the coping method.

In the invention of claim 2, since the terminal data includes at least one of the temperature, battery voltage, current consumption and operating state of the information terminal, the analysis unit can analyze the state of the information terminal in more detail. .. Therefore, when the temperature of the information terminal is abnormally high, the battery voltage is an abnormal value, the current consumption is an abnormal value, or the operating state of the information terminal is abnormal with respect to the requesting source. Can specifically notify the cause of the abnormality and how to deal with it.

In the invention of claim 3, the acceleration of the information terminal detected by the acceleration sensor is associated with the specific information and transmitted to the server by the transmitting unit. As a result, the server can acquire the acceleration of the information terminal that suddenly changes when the information terminal falls, etc., so the presence or absence of the information terminal falling, etc., which is detected according to the change in the acceleration of the information terminal, is taken into consideration. The state of the information terminal can be analyzed with, and the analysis accuracy can be improved.

In the invention of claim 4, the acceleration of the information terminal is acquired by the acquisition unit when the acceleration exceeds a predetermined acceleration threshold, and the acceleration of the information terminal acquired in this way is transmitted at a transmission timing different from the terminal data. It is sent to the server by the department. As a result, the acceleration of the information terminal, which is not expected to fall and is irrelevant to the cause of the failure, is not transmitted to the server, so that it is possible to suppress the transmission of unnecessary data to the server.

In the invention of claim 5, each time the terminal data and the specific information are received, the analysis unit analyzes the state of the information terminal specified from the specific information based on the received terminal data. Then, when the determination unit determines that the state of the information terminal should be warned based on the analysis result by the analysis unit, the information regarding the analysis result is displayed on the display unit.

As a result, the administrator or the like who is viewing the information regarding the analysis result displayed on the display unit can grasp in real time that the state of the information terminal to be managed is a state to be warned, so that the state to be warned It can be resolved quickly.

In the invention of claim 6, the information terminal is an information reading terminal capable of reading external information, and the terminal data includes at least a part of the read reading data associated with specific information. Then, in the server, in response to the request accompanied by the specific information, the read data stored in the terminal data storage unit regarding the specific information is output by the output unit to the request source.

As a result, even if the read data that has been read so far cannot be retrieved from the information terminal that has failed, the read data that has been periodically transmitted to the server can be obtained by requesting the server. Can be easily restored.

In the invention of claim 7 , the threshold storage unit of the information terminal has a value corresponding to the height of the light receiving waveform when the frequency of reading failures increases due to deterioration of the dustproof plate, and is the first threshold value. A value larger than the second threshold value is stored as the second threshold value, and if the height of the received light waveform continues to be equal to or lower than the second threshold value when the reflected light is received, the dustproof plate is deteriorated. Notification information is included in the terminal data transmitted by the transmitter. Then, in the server, when the terminal data analyzed by the analysis unit includes the second notification information, the notification unit notifies the requester that the dustproof plate has deteriorated.

As a result, the frequency of reading failures by the information terminal is high. Therefore, when the server is requested to accompany the specific information of the information terminal, the frequency of reading failures by the information terminal due to the deterioration of the dustproof plate becomes high. If so, the terminal data analyzed by the analysis unit of the server includes the second notification information, so that the requester is notified that the dustproof plate has deteriorated. Therefore, the user or the like of the information terminal who has made the above request can easily know the cause of the high frequency of reading failures and the countermeasures.

The communication unit 75 is configured as a known communication interface that communicates via a predetermined network N such as the Internet, and functions to communicate with an external device such as a terminal device 60 in cooperation with the control unit 71. To do.

The control unit 71 receives the terminal data or the like received from the terminal device 60 via the communication unit 75 by the terminal data registration process that is constantly performed, and uses specific information as a reference in a predetermined database provided in the storage unit 72 for each reception. Register to accumulate as sequentially. This database is constructed so that the terminal data and the like stored in relation to the specified specific information can be analyzed by the analysis process performed by the control unit 71. The control unit 71 that performs the analysis process may correspond to an example of the "analysis unit", and the storage unit 72 may correspond to an example of the "terminal data storage unit".

Further, the control unit 71 performs the above analysis process in response to the request from the request source, and notifies the request source of the analysis result. Specifically, the control unit 71 starts the analysis process by receiving the notification request of the analysis result accompanied by the specific information from the terminal device 60 by the request process performed by the control unit 61 of the terminal device 60. The analysis result is transmitted to the terminal device 60, which is the request source, via the communication unit 75 and notified. The control unit 71 and the communication unit 75 may correspond to an example of the “notification unit”.

In this analysis process, for example, since the voltage value of the battery 49a is abnormally lowered due to deterioration, the information terminal 10 does not start even if the power key is operated. When the above operation is performed, an abnormally low voltage value is recorded in the database of the storage unit 72 in relation to the specific information of the information terminal 10, and as an analysis result, the deterioration of the battery 49a is grasped. Therefore, it is possible to transmit information on the deterioration of the battery 49a, information prompting the replacement of the battery 49a, and the like to the terminal device 60. By displaying such an analysis result or the like on the display unit 64 of the terminal device 60, the user or the like can confirm the deteriorated state of the battery 49a and the coping method thereof. Further, in such a case, information such as "Is the battery inserted correctly?" May be displayed on the display unit 64. Further, if the abnormal state is not resolved even by the above-mentioned countermeasures, the battery 49a may be removed and information prompting the discontinuation of use may be displayed on the display unit 64.

Further, in the above analysis process, for example, since the temperature of the information terminal 10 continues to exceed a predetermined temperature (for example, 50 ° C.), the operation of the information terminal 10 is unstable, so that the information terminal 10 is operated via the terminal device 60. When the above-mentioned predetermined operation is performed, an abnormally high temperature is recorded in the database of the storage unit 72 in relation to the specific information of the information terminal 10, and as an analysis result, the temperature abnormality of the information terminal 10 is recorded. Be grasped. Therefore, it is possible to transmit information on the temperature abnormality of the information terminal 10 and information prompting the removal of the battery 49a to the terminal device 60. By displaying such an analysis result or the like on the display unit 64 of the terminal device 60, the user or the like can confirm the temperature abnormality of the information terminal 10 and the coping method thereof. Further, in such a case, information such as "Please contact the administrator" may be displayed on the display unit 64.

Further, in the analysis process, for example, since the information terminal 10 has fallen and failed, when the above-mentioned predetermined operation is performed via the terminal device 60, the database of the storage unit 72 contains the specific information of the information terminal 10. An abnormally large acceleration is recorded in connection with this, and as an analysis result, the fall of the information terminal 10 is grasped. Therefore, it is possible to transmit information and the like regarding the fall of the information terminal 10 to the terminal device 60. By displaying such an analysis result or the like on the display unit 64 of the terminal device 60, the user or the like can grasp that the cause of the failure is the fall of the information terminal 10.

In addition, assuming a state of the information terminal 10 that cannot be determined only by the received terminal data such as "information code cannot be read", "charging cannot be performed", "data communication cannot be performed", etc., the analysis process by the control unit 71 is performed on the terminal. An answer input in response to an operation by a user or the like to a question displayed on the display unit 64 of the device 60 may also be acquired from the terminal device 60 and analyzed. As a result, the terminal device 60 can notify the analysis result and the like by the display of the display unit 64 by receiving the state of the information terminal 10 analyzed and the like as described above and the coping method thereof from the server 70. ..

Further, in the above analysis process, for example, when it is determined that the terminal device 60 is in a normal state as a result of analyzing the terminal data or the like stored in relation to the requested specific information, the terminal device 60 is subjected to the analysis. Information indicating that the information terminal 10 is in a normal state can be transmitted. By displaying such an analysis result or the like on the display unit 64 of the terminal device 60, the user or the like can grasp that the information terminal 10 is in a normal state, and can continue the information terminal 10 with peace of mind. Can be used.

As described above, in the management system 1 according to the present embodiment, in the information terminal 10, terminal data and the like related to the state of the information terminal 10 are acquired by the terminal data acquisition unit 50, and the acquired terminal data and the like are specified. It is associated with the information and is periodically transmitted to the server 70 by the transmitter. Further, in the server 70, the data received from the information terminal 10 is stored in the database of the storage unit 72. Then, in the server 70, the state of the information terminal 10 specified from the specific information based on the terminal data or the like stored in the database in association with the specific information is determined by the control unit 71 in response to the request accompanied by the specific information. When the analysis is performed by the analysis process, the analysis result is transmitted to the terminal device 60, which is the request source, and notified.

As a result, when the information terminal 10 fails, the server 70 is requested to accompany the specific information that identifies the failed information terminal 10, and the analysis result of analyzing the state of the information terminal 10 is obtained. Since the notification is given, the state of the information terminal 10 to be managed can be easily confirmed based on the analysis result. In particular, since the server 70 periodically receives the terminal data acquired by the terminal data acquisition unit 50, for example, even if the information terminal 10 does not operate, it is periodically received by just before the failure. Since the terminal data that has been used can be analyzed, the cause of the failure can be easily investigated.

In particular, since the terminal data includes at least one of the temperature of the information terminal 10, the battery voltage (voltage of the battery 49a), the current consumption (current of the battery 49a), and the operating state, the analysis process by the control unit 71 includes information. The state of the terminal 10 can be analyzed in more detail. Therefore, when the temperature of the information terminal 10 is abnormally high, the battery voltage is an abnormal value, the current consumption is an abnormal value, or the operating state of the information terminal 10 is abnormal with respect to the requesting source. In that case, the cause of the abnormality and the coping method thereof can be specifically notified.

Further, the acceleration of the information terminal 10 detected by the acceleration sensor 53a is associated with the specific information and transmitted to the server 70 via the terminal device 60 by the BLE module 52 of the terminal data acquisition unit 50. As a result, the server 70 can acquire the acceleration of the information terminal 10 that suddenly changes when the information terminal 10 falls or the like, so that the information terminal 10 may fall or the like detected according to the change in the acceleration of the information terminal 10. The state of the information terminal 10 can be analyzed in consideration of the presence or absence, and the analysis accuracy can be improved.

In particular, the acceleration of the information terminal 10 is acquired by the terminal data acquisition unit 50 when the acceleration exceeds a predetermined acceleration threshold by using the comparator 54, and the acceleration of the information terminal 10 acquired in this way is the terminal data. Is transmitted to the server 70 by the BLE module 52 via the terminal device 60 at different transmission timings. As a result, the acceleration of the information terminal 10 that is not expected to fall or is irrelevant to the cause of the failure is not transmitted to the server 70, so that the transmission of unnecessary data to the server 70 and the terminal device 60 is suppressed. can do.

Since the storage unit 72 of the server 70 stores the read data read by each information terminal 10 in association with the specific information, the specific information of the information terminal 10 that has been determined to be faulty with respect to the server 70. By requesting the output of the read data so as to accompany the above, the read data or the like read so far by the information terminal 10 can be output to the requesting source in response to the output process by the control unit 71. In this case, for example, a substitute for the information terminal 10 whose failure has been determined is prepared, the substitute is placed on a cradle connected to the terminal device 60 via USB, and the output request from the terminal device 60 is met. The read data received from the server 70 can be taken into the alternative product via the cradle. The control unit 71 may correspond to an example of the “output unit”.

As a result, even if the read data read so far cannot be taken out from the information terminal 10 that has failed, the read data that has been periodically transmitted to the server 70 can be obtained by requesting the server 70. , The read data can be easily recovered.

[Second Embodiment]
Next, the management system according to the second embodiment of the present invention will be described with reference to FIG.
The second embodiment is mainly different from the first embodiment in that the state of the corresponding information terminal is analyzed by the server each time the terminal data or the like is received. Therefore, substantially the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the server 70 of the present embodiment, even if there is no request from the terminal device 60, each time the terminal data and specific information are received via the terminal device 60, the information specified from the specific information based on the terminal data is received. The state of the terminal 10 is analyzed. Then, when it is determined that the state of the information terminal 10 is a state to be warned based on the analysis result, the information regarding the analysis result and the like is transmitted to the terminal device 60 and displayed on the display unit 64. As a result, the user or the like who sees the analysis result or the like displayed on the display unit 64 can easily grasp the state of the information terminal 10 in which the abnormality has occurred.

Here, the state to be warned is, for example, a state in which the temperature T of the information terminal 10 is equal to or higher than a predetermined temperature To (for example, 50 ° C.), or a state in which the battery voltage (voltage of the battery 49a) V is 0 V or lower.

It is determined whether or not it is To or higher. Here, if the temperature T of the information terminal 10 is less than the predetermined temperature To, it is determined as No in step S401, and the battery voltage V included in the received terminal data or the like in the determination process of step S403 is 0 V or less. It is determined whether or not it is. Here, if the battery voltage V exceeds 0 V, it is determined as No in step S403, and it is determined in the determination process of step S405 whether or not the battery voltage V is equal to or less than the voltage threshold value Vo. Here, if the battery voltage V exceeds the voltage threshold value Vo, it is determined as No in step S405, and the current consumption I included in the received terminal data or the like in the determination process in step S407 is equal to or greater than the current threshold value Io. It is determined whether or not it is. Here, if the current consumption I is less than the current threshold value Io, it is determined as No in step S407, and the received terminal data or the like is registered (stored) in the database of the storage unit 72 based on the specific information (S409). , This analysis process is completed. The control unit 71 that performs the determination process in steps S401, S403, S405, and S407 may correspond to an example of the "determination unit".

On the other hand, if the temperature T of the information terminal 10 included in the received terminal data or the like is equal to or higher than the predetermined temperature To, it is determined to be Yes in step S401, and the notification process shown in step S411 is performed. In this process, for example, warning information including the abnormal temperature state of the information terminal 10 and its countermeasures, such as "The temperature is abnormal. Please remove the battery immediately and contact the administrator." Is specific information. Is associated with and transmitted to the corresponding terminal device 60. In the terminal device 60, the warning information as described above is displayed on the display unit 64 and notified, so that the user or the like can confirm that the corresponding information terminal 10 has a temperature abnormality and how to deal with it.

If the battery voltage V included in the received terminal data or the like is 0 V or less, it is determined to be Yes in step S403, and the notification process shown in step S413 is performed. In this process, for example, warning information including the abnormal state of the battery voltage of the information terminal 10 and the countermeasures, such as "Battery voltage is abnormal. Please check if the battery is installed correctly." Is specific information. Is associated with and transmitted to the corresponding terminal device 60. In the terminal device 60, the warning information as described above is displayed on the display unit 64 and notified, so that the user or the like can confirm the battery abnormality state of the corresponding information terminal 10 and the coping method thereof.

Further, if the battery voltage V included in the received terminal data or the like exceeds 0 V but is equal to or less than the voltage threshold value Vo, it is determined to be Yes in step S405, and the notification process shown in step S415 is performed. In this process, warning information including the low battery voltage state of the information terminal 10 and the countermeasures, such as "Battery voltage is low. Please charge immediately or remove the battery." Is specified. It is associated with the information and transmitted to the corresponding terminal device 60. In the terminal device 60, the warning information as described above is displayed on the display unit 64 and notified, so that the user or the like can confirm the battery voltage drop state of the corresponding information terminal 10 and the coping method thereof. ..

If the current consumption I included in the received terminal data or the like is equal to or greater than the current threshold value Io, it is determined to be Yes in step S407, and the notification process shown in step S417 is performed. In this process, for example, warning information including the abnormal current consumption state of the information terminal 10 and its countermeasures, such as "The current value is abnormal. Please remove the battery immediately and contact the administrator." It is associated with the specific information and transmitted to the corresponding terminal device 60. In the terminal device 60, the warning information as described above is displayed on the display unit 64 and notified, so that the user or the like can confirm the current consumption abnormal state of the corresponding information terminal 10 and the coping method thereof. ..

As described above, in the management system 1 according to the present embodiment, each time the terminal data and the specific information are received by the analysis process in the control unit 71 of the server 70, the management system 1 is specified from the specific information based on the received terminal data. The state of the information terminal 10 is analyzed. Then, when it is determined that the state of the information terminal 10 is a state to be warned based on the analysis result by the analysis process, the information regarding the analysis result is transmitted to the terminal device 60 and displayed on the display unit 64.

As a result, the administrator or the like who is viewing the information regarding the analysis result displayed on the display unit 64 can grasp in real time that the state of the information terminal 10 to be managed is a state to be warned, and therefore should be warned. The condition can be resolved quickly.

In the analysis process according to the present embodiment, the state of the information terminal 10 is analyzed by using not only the received terminal data but also at least a part of the terminal data of the database that has been received and accumulated so far. May be good.

Further, since the server 70 can collectively manage a plurality of information terminals 10, information on the latest state of each of the plurality of information terminals 10 is collectively transmitted to the corresponding terminal device 60 at a predetermined timing. You may. In this case, as illustrated in FIG. 9, the terminal device 60 can notify the latest state of each information terminal 10 by the display of the display unit 64, including the presence or absence of the warning state. In such a display state, the details of the warning regarding the selected information terminal 10 and the coping method thereof may be further displayed on the display unit 64 in response to the selection operation of the information terminal 10 by the user or the like.

[Third Embodiment]
Next, the management system according to the third embodiment of the present invention will be described with reference to FIGS. 10 to 12.
The third embodiment is mainly different from the first embodiment in that the deterioration state of the dustproof plate 13 of the information terminal 10 can be notified. Therefore, substantially the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the information terminal 10 configured as described above, when the dustproof plate 13 becomes cloudy due to deterioration over time, when a one-dimensional code is imaged by the light receiving sensor 23, the barcode B illustrated in FIG. 10A is illustrated. The difference in brightness between the light color module (white space) and the dark color module (black bar) becomes unclear. Therefore, when the height of the light receiving waveform Sb obtained from the difference in brightness before the dustproof plate 13 becomes cloudy is hb, and the degree of cloudiness of the dustproof plate 13 increases as illustrated in FIG. 10B. The height h of the received light waveform S of the above becomes low, and there is a high possibility that the decoding (decoding) of the one-dimensional code will fail. Therefore, when reading fails due to deterioration of the dustproof plate 13, it is desirable to notify the replacement of the dustproof plate 13. The height of the received light waveform can be obtained from the difference between the highest brightness and the lowest lightness of the received light waveform.

On the other hand, even if the same one-dimensional code is imaged, the height h of the received light waveform S changes according to the distance to the one-dimensional code. Specifically, as shown in FIG. 11 (A), the reflected light from the nearby one-dimensional code was received, and as shown in FIG. 11 (B), the reflected light from the distant one-dimensional code was received. In some cases, the height h of the light receiving waveform S of the distant one-dimensional code is lower than the height h of the light receiving waveform S of the near one-dimensional code. Then, it is not possible to know whether the dustproof plate 13 has deteriorated only by the height h of the light receiving waveform S.

Therefore, in the present embodiment, in the deterioration degree detection process performed by the control unit 40 when the information terminal 10 reads the one-dimensional code, the height h of the received light waveform S is substantially the same value and is continuously determined. When the threshold value is equal to or less than the threshold value ho, deterioration information indicating that the dustproof plate 13 needs to be replaced is generated. Then, the control unit 40 includes the deterioration information generated in this way in the current operating state of the information terminal 10 and outputs the deterioration information to the terminal data acquisition unit 50. The predetermined threshold value ho corresponds to an example of the “first threshold value”, and is set to a value corresponding to the height of the received light waveform when reading fails due to deterioration of the dustproof plate 13 and is set in the memory. It is stored in advance in 35. Further, the memory 35 may correspond to an example of the "threshold storage unit", and the deterioration information may correspond to an example of the "first notification information".

Hereinafter, the degree of deterioration detection process performed by the control unit 40 of the information terminal 10 in the present embodiment will be described in detail with reference to the flowchart shown in FIG.
When the control unit 40 starts the deterioration degree detection process by performing a predetermined operation on the operation unit 42, the initial setting process shown in step S501 is performed. In this process, when the height h of the received light waveform S is substantially the same value and the state of being equal to or less than the predetermined threshold value Δho continues, the number of continuations n when it is determined that the dustproof plate 13 is deteriorated. Etc. are set to predetermined values. In the present embodiment, the initial value of the number of continuations n is set to, for example, several times.

Next, in the determination process shown in step S503, it is determined whether or not the reading process separately performed by the control unit 40 is successful, and if the reading process is successful (Yes in S503), the deterioration degree detection process is performed. Is finished. On the other hand, if the reading process fails (No in S503), the height h of the received light waveform S is stored in the memory 35 in the process shown in step S505. Subsequently, in the determination process shown in step S507, whether the difference Δh between the height h of the current received light waveform S and the height h of the previous received light waveform S stored in the memory 35 is equal to or less than the predetermined threshold value Δho. It is judged whether or not. Here, if the height h of the current received light waveform S and the height h of the previous received light waveform S stored in the memory 35 are different and the difference Δh exceeds a predetermined threshold value Δho, the reading process fails. Therefore, assuming that the distance between the information terminal 10 and the one-dimensional code is changed, No is determined in step S507, and the process from step S501 is performed.

On the other hand, when the height h of the current received light waveform S and the height h of the previous received light waveform S stored in the memory 35 are substantially the same and the difference Δh is equal to or less than a predetermined threshold value Δho (in S507). Yes), in the determination process shown in step S509, it is determined whether or not the height h of the received light waveform S is equal to or less than a predetermined threshold value ho.

Here, when the height h of the received light waveform S exceeds the predetermined threshold value ho (No in S509), it is assumed that the dustproof plate 13 has not deteriorated, and the process from step S501 is performed.

On the other hand, when the height h of the received light waveform S is equal to or less than a predetermined threshold value ho (Yes in S509), the number of continuations n is decremented (S511), and the number of continuations decremented in the determination process shown in step S513 is performed. It is determined whether or not n is 0. Here, if the number of continuations n is not 0, it is determined as No in step S513, and it is assumed that the state in which the height h of the received light waveform S is less than the predetermined threshold value ho is not continued, and from step S503 above. Is processed.

On the other hand, since the state in which the height h of the received light waveform S is less than the predetermined threshold value ho continues, when the number of decremented continuations n becomes 0 (Yes in S513), the height h of the received light waveform S becomes. The deterioration information is generated on the assumption that the state of being less than the predetermined threshold value ho continues (S515).

Then, the deterioration information generated in this way is included in the current operating state of the information terminal 10 and output to the terminal data acquisition unit 50, and further transmitted to the server 70 via the terminal device 60. When the server 70 makes a request with specific information corresponding to the information terminal 10 in which the dustproof plate 13 is deteriorated in this way, the server 70 notifies the requester of the terminal device 60 or the like of the deterioration of the dustproof plate 13. Can be done.

As described above, in the management system 1 according to the present embodiment, the information terminal 10 receives the reflected light from the one-dimensional code through the dustproof plate 13 by the light receiving sensor 23, and based on the light receiving waveform S thereof. An information code reading terminal that optically reads the one-dimensional code, and a value corresponding to the height h of the light receiving waveform S when reading fails due to deterioration of the dustproof plate 13 is set as a predetermined threshold value ho. It is stored in 35. Then, in the information terminal 10, if the height h of the received light waveform S continues to be equal to or less than a predetermined threshold value ho when the reflected light is received, the deterioration information (first) indicating that the dustproof plate 13 needs to be replaced. Notification information) is included in the terminal data transmitted by the BLE module 52. Then, in the server 70, if the terminal data analyzed by the analysis process performed by the control unit 71 includes the deterioration information, it is necessary to replace the dustproof plate 13 with respect to the requesting terminal device 60. You will be notified that there is.

As a result, the reading by the information terminal 10 is not successful. Therefore, when the server 70 is requested to accompany the specific information of the information terminal 10, the information terminal 10 fails to read due to the deterioration of the dustproof plate 13. If so, the terminal data analyzed by the server 70 includes the above-mentioned deterioration information, so that the requester is notified that the dustproof plate 13 needs to be replaced. Therefore, the user or the like of the information terminal 10 who has made the above request can easily know the cause of the reading failure and the coping method.

The second threshold value is a value corresponding to the height h of the light receiving waveform S when the frequency of reading failures increases due to deterioration of the dustproof plate 13 and larger than the predetermined threshold value ho. If the height h of the received light waveform S continues to be equal to or less than the second threshold value when the reflected light is received in the state stored in the memory 35, a second notification indicating that the dustproof plate 13 has deteriorated is given. Information may be generated and included in the terminal data transmitted by the BLE module 52.

As a result, since the frequency of reading failures by the information terminal 10 is high, when the server 70 is requested to accompany the specific information of the information terminal 10, the information terminal 10 fails to read due to the deterioration of the dustproof plate 13. When the frequency is high, the terminal data analyzed by the server 70 includes the second notification information, so that the requester is notified that the dustproof plate 13 has deteriorated. .. Therefore, the user or the like of the information terminal 10 who has made the above request can easily know the cause of the high frequency of reading failures and the coping method. Further, the user or the like can know that the dustproof plate 13 is about to be replaced.

Further, in the deterioration degree detection process performed by the control unit 40, the height h of the received light waveform S is set in consideration of both the height h of the received light waveform S, the predetermined threshold value ho, and the second threshold value. When the state of being equal to or less than the second threshold value continues, the height h of the received light waveform S becomes equal to or less than the predetermined threshold value ho without including the second notification information in the terminal data and then replacing the dustproof plate 13. If the state continues, the deterioration information (first notification information) may be included in the terminal data.

Further, when the deterioration information (first notification information) or the second notification information is generated as described above, the information terminal 10 itself replaces the dustproof plate 13 by using the display or the like displayed by the display unit 43. May be notified to the user and the like that the dustproof plate 13 is required and that the dustproof plate 13 is deteriorated. In such a configuration, in order to suppress excessive notification, for example, the deterioration degree detection process may be performed only when the mode is switched to a predetermined test mode.

Further, when dust or the like adheres to the dustproof plate 13, the portion of the light-receiving waveform corresponding to that portion always corresponds to a dark color. Good. Further, even if the terminal data transmitted by the BLE module 52 includes information indicating that dust or the like is attached to the dustproof plate 13 when a part of the received light waveform is always equivalent to a dark color as described above. Well, in this case, it is possible to notify the requester that dust or the like is attached to the dustproof plate 13. Further, the information terminal 10 itself may notify the user or the like that dust or the like is attached to the dustproof plate 13.

The characteristic configuration of the present embodiment and the modified example for notifying the deterioration state of the dustproof plate 13 of the information terminal 10 can be applied to other embodiments.

In this case, the terminal device 60 analyzes the terminal data and the like stored in relation to the specified specific information by the analysis process performed by the control unit 61 as in the server 70, and the analysis result and the coping method. Etc. can be displayed on the display unit 64 to notify the user.
