Description

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

  At present, an information terminal such as an information code reading terminal which optically reads an information code is used in various applications in various environments. By the way, in such an information terminal, if it breaks down during use, it will lose the read data read till then, and there is a possibility that losses such as re-doing of business may occur.

It facilitates data recovery without losing data ever acquired.

JP, 2015-219699, A

  By the way, when an operation abnormality or a failure occurs in the information terminal itself, generally the user does not know the coping method, and it is necessary to inquire to the administrator, etc., and it often takes time for the recovery. On the other hand, even if the manager hears the usage situation at the time of breakdown etc. from the user in order to confirm the cause of the breakdown etc., the information to be heard from the user is often vague memory and useful information Is likely not to be obtained.

  With regard to such a problem, in the configuration in which information such as operation log is successively stored in the flash ROM etc. in the information terminal, the manufacturer can analyze the operation log etc stored therein at the time of failure and try to investigate the cause. However, the user can not confirm the operation log or the like, and even if the user can confirm it, the cause can not be investigated. In particular, in the configuration in which information such as the operation log is stored in the flash ROM, there is a limit to the amount of data that can be stored, and even in the case of a failure where information can not be extracted from the flash ROM etc. in the first place There is also a situation that can be said.

  The present invention has been made to solve the above-described problem, 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:
One or more information terminals (10),
A server (70) for managing data received from the information terminal;
A management system (1) comprising
The information terminal is

A transmitting unit (52) periodically transmitting the terminal data acquired by the acquiring unit to the server in association with specific information that can specify the information terminal;
Equipped with
The server is
A terminal data storage unit (72) in which data received from the information terminal is stored;
In response to a request accompanied by the specific information, an analysis unit (71 for analyzing 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 )When,
A notification unit (71, 75) for notifying the request source (60) of the analysis result of the analysis unit;
And the like.
In addition, the code | symbol in each said bracket shows correspondence with the specific means as described in embodiment mentioned 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 the specific information and periodically transmitted to the server by the transmission unit. Be done. Also, in the server, data received from the information terminal is stored in the terminal data storage unit. Then, in response to the request accompanied with the specific information, the server 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, the analysis unit is notified of the analysis result to the request source.

  As a result, when the information terminal fails or the like, the server is requested to be accompanied by the specific information for specifying the failed information terminal, so that the analysis result in which the state of the information terminal is analyzed is notified. The state of the information terminal to be managed can be easily confirmed based on the analysis result. In particular, in the server, since the terminal data acquired by the acquisition unit is periodically received, for example, even if there is a malfunction such that the information terminal does not operate, the terminal data that has been received regularly just before that malfunction Can be analyzed, so that the cause of the failure can be easily investigated.

  In the invention of claim 2, the terminal data includes at least one of the temperature of the information terminal, the battery voltage, the consumption current, and the operation state, so that 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 consumption current is an abnormal value, or the operation state of the information terminal is abnormal. Can specifically notify of the cause of the abnormality and the coping method.

  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 by the transmitting unit to the server. As a result, the server can acquire the acceleration of the information terminal which suddenly changes when the information terminal falls or the like, and therefore, the presence or absence of the information terminal detected according to the change of the acceleration of the information terminal is considered. The state of the information terminal can be analyzed 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 of the information terminal becomes equal to or higher than the predetermined acceleration threshold, and the acceleration of the information terminal acquired in this manner is transmitted at a transmission timing different from the terminal data. Sent to the server by the As a result, since an acceleration of the information terminal which is not assumed to fall or the like and becomes irrelevant to the cause of the failure is not transmitted to the server, it is possible to suppress transmission of unnecessary data to the server.

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

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

  As a result, even if the read data read so far can not be extracted from the failed information terminal, the read data that has been periodically transmitted to the server can be acquired by requesting the server, so the read data can be obtained. The recovery can be done easily.

  In the invention of claim 7, the information terminal receives the reflected light from the one-dimensional code by the light receiving section through the dustproof plate, and the information code reading terminal optically reads the one-dimensional code based on the light reception waveform. A value corresponding to the height of the light reception waveform when reading fails due to deterioration of the dustproof plate is stored as a first threshold in the threshold storage unit. Then, in the information terminal, the first notification information indicating that the dust-proof plate needs to be replaced is the transmitting unit when the state in which the height of the light reception waveform becomes equal to or less than the first threshold continues when receiving the reflected light. Included in the terminal data transmitted by the Then, in the server, when the first notification information is included in the terminal data analyzed by the analysis unit, the notification unit notifies the request source that the dustproof plate needs to be replaced.

  As a result, since reading by the information terminal is not successful, if the server is requested to be accompanied by the specific information of the information terminal, if the information terminal fails in reading due to deterioration of the dustproof plate, Since the first notification information is included in the terminal data analyzed by the analysis unit of the server, the request source is notified that the dustproof plate needs to be replaced. Therefore, the user or the like of the information terminal which has made the above request can easily know the cause of the reading failure and the coping method.

  In the invention of claim 8, the threshold storage unit of the information terminal has a value corresponding to the height of the light reception waveform when the frequency of reading failure becomes high due to the deterioration of the dustproof plate, and the first threshold A second value which is larger than the second threshold value is stored, and the second plate indicates that the dustproof plate is deteriorated if the state in which the height of the light reception waveform is smaller than the second threshold continues when the reflected light is received. The notification information of is included in the terminal data transmitted by the transmission unit. Then, in the server, when the terminal data analyzed by the analysis unit includes the second notification information, the notification unit notifies the request source that the dustproof plate is deteriorated.

  As a result, since the frequency of reading failure by the information terminal is high, when the server is requested to accompany the specific information of the information terminal, the frequency of reading failure of the information terminal is increased due to the deterioration of the dustproof plate. If the terminal information analyzed by the analysis unit of the server includes the second notification information, the request source is notified that the dustproof plate is deteriorated. Therefore, the user or the like of the information terminal which has made the above request can easily know the cause of the high frequency of reading failure and the method of coping with it.

Register to be accumulated sequentially as The database is constructed such that terminal data and the like stored in association with the specified specific information can be analyzed by analysis processing performed by the control unit 71. Note that the control unit 71 that performs analysis processing corresponds 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 notifies the request source of the analysis result by performing the above-mentioned analysis processing in response to the request from the request source. Specifically, by the request processing performed by the control unit 61 of the terminal device 60, the analysis processing is started by the control unit 71 by receiving a notification request for analysis results accompanied by specific information from 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 can correspond to an example of a “notification unit”.

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

  Further, in the above analysis process, for example, since the state in which the temperature of the information terminal 10 exceeds the predetermined temperature (for example, 50 ° C.) continues, the operation of the information terminal 10 is unstable. When the 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. As an analysis result, the temperature abnormality of the information terminal 10 is Be grasped. Therefore, it is possible to transmit, to the terminal device 60, information related to temperature abnormality of the information terminal 10, information prompting removal of the battery 49a, and the like. By displaying such an analysis result etc. on the display part 64 of the terminal device 60, the user etc. can confirm the temperature abnormality of the information terminal 10, and the coping method. 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, when the information terminal 10 falls and breaks down, when the predetermined operation is performed via the terminal device 60, the database of the storage unit 72 contains the identification information of the information terminal 10 In connection with this, a large acceleration is recorded abnormally, and a drop of the information terminal 10 is grasped as an analysis result. Therefore, it is possible to transmit, to the terminal device 60, information and the like related to the falling of the information terminal 10. By displaying such an analysis result etc. on the display part 64 of the terminal device 60, the user etc. can grasp | ascertain that the cause of a failure exists in the fall of the information terminal 10. FIG.

  In addition, assuming that the information terminal 10 can not be judged only by the received terminal data, such as “the information code can not be read”, “the battery can not be charged” and “the data can not be communicated” It is also possible to obtain, from the terminal device 60, an answer input according to the operation of the user or the like with respect to the question item displayed on the display unit 64 of the device 60 and analyze it. Thereby, the terminal device 60 can notify the analysis result and the like by the display of the display unit 64 by receiving from the server 70 the state of the information terminal 10 analyzed as described above and its countermeasure. .

  Further, in the analysis processing, for example, when it is determined that the terminal data and the like stored in association with the requested specific information are in a normal state, the terminal device 60 is Information indicating that the information terminal 10 is in a normal state can be transmitted. By displaying such an analysis result etc. on the display unit 64 of the terminal device 60, the user etc. can grasp that the information terminal 10 is in a normal state, and continue the information terminal 10 in peace. 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 identified. The transmission unit periodically transmits the information to the server 70 in association with the information. 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, in response to the request accompanied by the specific information, the state of the information terminal 10 specified from the specific information based on the terminal data etc. stored in the database in association with the specific information When analyzed by the analysis process, the analysis result is transmitted to the terminal device 60 as the request source and notified.

  As a result, when the information terminal 10 breaks down, the server 70 requests the server 70 to be accompanied by specific information that specifies the failed information terminal 10, and the analysis result of analyzing the state of the information terminal 10 is 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, in the server 70, since the terminal data acquired by the terminal data acquisition unit 50 is periodically received, for example, even if the malfunction is such that the information terminal 10 does not operate, it is periodically received immediately before the malfunction Since the terminal data that was being analyzed can be analyzed, it is possible to easily investigate the cause of the failure.

  In particular, since the terminal data includes at least one of the temperature of the information terminal 10, the battery voltage (the voltage of the battery 49a), the consumption current (the current of the battery 49a) and the operation state, 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, or the consumption current is an abnormal value, the operation state of the information terminal 10 is abnormal. In the case, it is possible to specifically notify of the cause of the abnormality and the coping method.

  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 by the BLE module 52 of the terminal data acquisition unit 50 via the terminal device 60. Thus, the server 70 can acquire the acceleration of the information terminal 10 that suddenly changes when the information terminal 10 falls or the like. Therefore, the fall of the information terminal 10 detected according to the change of 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 the predetermined acceleration threshold value by using the comparator 54, and the acceleration of the information terminal 10 acquired in this manner is the terminal data Are transmitted to the server 70 via the terminal device 60 by the BLE module 52 at different transmission timings. As a result, the acceleration of the information terminal 10 is not transmitted to the server 70 which is not assumed to fall or become irrelevant to the cause of the failure, and therefore unnecessary transmission of data to the server 70 and the terminal device 60 is suppressed. can do.

  In addition, since the read data read by each information terminal 10 is stored in the storage unit 72 of the server 70 in association with the specific information, the specific information of the information terminal 10 determined to be defective with respect to the server 70 is stored. By requesting the output of the read data so as to cause the read data, it is possible to output the read data or the like read by the information terminal 10 so far to the request source according to the output processing by the control unit 71. In this case, for example, a substitute for the information terminal 10 determined to be defective is prepared, and the substitute is placed on a cradle connected to the terminal device 60 by USB, and the output request from the terminal device 60 is issued. The read data received from the server 70 can be taken into a substitute via the cradle. The control unit 71 can correspond to an example of the “output unit”.

  As a result, even if the read data read so far can not be taken out from the failed information terminal 10, the read data sent periodically to the server 70 can be acquired by requesting the server 70. The read data can be easily restored.

In addition, the control part 71 which performs the determination process of said step S401, S403, S405, S407 can be corresponded to an example of a "determination part."

  On the other hand, if the temperature T of the information terminal 10 included in the received terminal data and the like is equal to or higher than the predetermined temperature To, it is determined as Yes in step S401 and notification processing shown in step S411 is performed. In this process, for example, warning information such as “The temperature is abnormal. Please remove the battery immediately and contact the administrator.” And the like, and the warning information including the temperature abnormal state of the information terminal 10 and the countermeasure And is transmitted to the corresponding terminal device 60. In the terminal device 60, when the warning information as described above is displayed on the display unit 64 and notified, the user or the like can confirm the temperature abnormality of the corresponding information terminal 10 and the coping method.

  If the battery voltage V included in the received terminal data or the like is 0 V or less, it is determined as Yes in step S403, and the notification process shown in step S413 is performed.

In this process, for example, warning information including the battery voltage drop state of the information terminal 10 and its handling method such as “Battery voltage has dropped. Please charge or remove the battery immediately.” Is specified. It is transmitted to the corresponding terminal device 60 in association with the information. 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 consumed current I included in the received terminal data or the like is equal to or greater than the current threshold Io, it is determined as Yes in step S407, and notification processing shown in step S417 is performed.

In the terminal device 60, the warning information as described above is displayed on the display unit 64 and notified, whereby the user etc. 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, by the analysis processing in the control unit 71 of the server 70, identification is made from the identification information based on the received terminal data each time the terminal data and the identification information are received. The state of the information terminal 10 is analyzed. Then, if 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 processing, information on the analysis result is transmitted to the terminal device 60 and displayed on the display unit 64.

In such a display state, the display unit 64 may further display the details of the warning related to the selected information terminal 10 and the countermeasure according to the selection operation of the information terminal 10 by the user or the like.

Third Embodiment
Next, a management system according to a third embodiment of the present invention will be described with reference to FIGS.
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. For this reason, the same code | symbol is attached | subjected to a substantially the same component as 1st Embodiment, and description is abbreviate | omitted.

  In the information terminal 10 configured as described above, when the dustproof plate 13 becomes cloudy due to deterioration with age, when the one-dimensional code is imaged by the light receiving sensor 23, the bar code B illustrated in FIG. Between the light module (white space) and the dark module (black bar) become unclear. For this reason, when the height of the light reception waveform Sb obtained from the contrast is set to hb before the dustproof plate 13 becomes cloudy, the degree of fogging of the dustproof plate 13 is increased as illustrated in FIG. The height h of the light reception waveform S decreases, and the possibility of failure in decoding of the one-dimensional code increases. Therefore, when the reading fails due to the deterioration of the dustproof plate 13, it is desirable to notify the replacement of the dustproof plate 13. The height of the light reception waveform can be obtained from the difference between the highest lightness and the lowest lightness in the light reception waveform.

  On the other hand, even if the same one-dimensional code is imaged, the height h of the light reception waveform S changes according to the distance to the one-dimensional code. Specifically, when reflected light from a nearby one-dimensional code is received as shown in FIG. 11 (A) and reflected light from a distant one-dimensional code is received as shown in FIG. 11 (B) In the case, the height h of the light reception waveform S of the distant one-dimensional code is lower than the height h of the light reception waveform S of the nearby one-dimensional code. Then, it is not clear that the dustproof plate 13 is deteriorated only by the height h of the light reception waveform S.

  Therefore, in the present embodiment, the height h of the light reception waveform S is substantially the same value in the deterioration degree detection process performed by the control unit 40 when the one-dimensional code is read by the information terminal 10, and thus predetermined In the case where the threshold value is less than or equal to the threshold value ho, degradation information indicating that the dustproof plate 13 needs to be replaced is generated. Then, control unit 40 includes the degradation information thus generated in the current operation state of information terminal 10 and outputs the degradation information to 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 light reception waveform when reading fails due to the deterioration of the dustproof plate 13. It is stored in advance in 35. In addition, 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 deterioration degree 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 deterioration degree detection process is started by the control unit 40 by performing a predetermined operation on the operation unit 42, an initial setting process shown in step S501 is performed. In this process, when it is determined that the dustproof plate 13 is degraded when the height h of the light reception waveform S continues to be approximately the same value and smaller than or equal to the predetermined threshold value Δho, the number n of times of continuation 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 the reading process separately performed by the control unit 40 is successful or not, and if the reading process is successful (Yes in S503), this deterioration degree detection process Ends. On the other hand, when the reading process fails (No in S503), the height h of the light reception waveform S is stored in the memory 35 in the process shown in step S505. Subsequently, in the determination processing shown in step S507, whether the difference Δh between the height h of the current light reception waveform S and the height h of the previous light reception waveform S stored in the memory 35 is less than or equal to a predetermined threshold Δho It is judged about whether or not. Here, if the height h of the current light reception waveform S is different from the height h of the previous light reception waveform S stored in the memory 35 and the difference Δh exceeds the 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, it is determined as No in Step S507, and the process from Step S501 is performed.

  On the other hand, if the height h of the current light reception waveform S and the height h of the previous light reception waveform S stored in the memory 35 are substantially the same and the difference .DELTA.h is less than or equal to the predetermined threshold value .DELTA.ho (S507 Yes) In the determination processing shown in step S509, it is determined whether the height h of the light reception waveform S is equal to or less than a predetermined threshold value ho.

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

  On the other hand, if the height h of the light reception waveform S is equal to or less than the predetermined threshold value ho (Yes in S509), the number of continuations n is decremented (S511), and the number of continuations decremented in the determination processing shown in step S513. It is determined whether n is 0 or not. 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 light reception waveform S is less than the predetermined threshold ho does not continue. Processing is performed.

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

  Then, the degradation information generated in this manner is included in the current operation state of the information terminal 10, is output to the terminal data acquisition unit 50, and is further transmitted to the server 70 via the terminal device 60. In the server 70, when the request accompanied by the specific information corresponding to the information terminal 10 in which the dustproof plate 13 is deteriorated is made in this way, the deterioration of the dustproof plate 13 is notified to the request source such as the terminal device 60. Can.

  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 by the light receiving sensor 23 through the dustproof plate 13, and based on the light receiving waveform S thereof. An information code reading terminal for optically reading the one-dimensional code, wherein a value corresponding to the height h of the light reception waveform S when reading fails due to deterioration of the dustproof plate 13 is stored as a predetermined threshold value ho It is stored in 35. Then, in the information terminal 10, deterioration information indicating that the replacement of the dustproof plate 13 is necessary if the height h of the light reception waveform S continues to be equal to or less than the predetermined threshold value ho during reception of the reflected light (first Notification information is included in the terminal data transmitted by the BLE module 52. Then, in the server 70, when the terminal data analyzed by the analysis processing performed by the control unit 71 includes the deterioration information, it is necessary to replace the dustproof plate 13 with the terminal device 60 that is the request source. It is notified that there is.

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

  Note that a value corresponding to the height h of the light reception waveform S when the frequency of reading failure increases due to the deterioration of the dustproof plate 13 and a value larger than the predetermined threshold value ho is used as the second threshold value. In the state stored in the memory 35, a second notification indicating that the dustproof plate 13 is degraded if the height h of the light reception waveform S continues to be equal to or less than the second threshold when receiving the reflected light Information may be generated and included in the terminal data sent by the BLE module 52.

  As a result, since the frequency of reading failure by the information terminal 10 is high, if the server 70 is requested to accompany the specific information of the information terminal 10, the reading failure of the information terminal 10 due to the deterioration of the dustproof plate 13. If the frequency is high, the terminal data analyzed by the server 70 includes the second notification information, so that the request source is notified that the dustproof plate 13 is degraded. . Therefore, the user or the like of the information terminal 10 which has made the above request can easily know the cause of the high frequency of reading failure and the coping method. Furthermore, the user can also know that the time to replace the dustproof plate 13 is near.

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

  In addition, when the deterioration information (the first notification information is) or the second notification information is generated as described above, the information terminal 10 itself is replaced with the dustproof plate 13 by using the display or the like by the display unit 43. May be notified to the user etc. that the dustproof plate 13 is deteriorated. In such a configuration, in order to suppress an excessive notification, for example, the above-mentioned deterioration degree detection processing may be performed only when switching to a predetermined test mode.

  Further, when dust or the like adheres to the dustproof plate 13, the portion of the light reception waveform corresponding to the location always becomes dark, so even if the portion of such light reception waveform is removed, the above-mentioned deterioration degree detection processing is performed Good. Furthermore, even if part of the light reception waveform always corresponds to a dark color as described above, even if information indicating that dust etc. is attached to the dustproof plate 13 is included in the terminal data transmitted by the BLE module 52. In this case, the request source can be notified that dust or the like is attached to the dustproof plate 13. In addition, the information terminal 10 itself may notify the user or the like that dust or the like is attached to the dustproof plate 13.

  In addition, the characteristic configuration of the present embodiment and the modification for notifying the deterioration state and the like of the dustproof plate 13 of the information terminal 10 can be applied to the other embodiments.
