[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a remote maintenance notification system that monitors a maintenance target device with a maintenance management device and reports a monitoring result to a remote central maintenance device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for equipment such as industrial machines that require regular maintenance, a company that has delivered the equipment or a certified company has undertaken maintenance work. However, the number of companies that specialize in maintenance, targeting new machines from various industries and various machines with low prices as weapons, is increasing, and competition for maintenance orders is intensifying. As in other service industries, it is a labor cost that requires a great deal of cost in the maintenance work, and one person is in charge of many devices in order to carry out the work efficiently with a minimum number of service personnel.
[0003]
In addition to the regular inspections that have been performed in the past, the concept of reducing the maintenance cost of machines overall has been spreading by adopting a method of performing preventive maintenance by constantly monitoring the state of the machines. .
[0004]
As described above, there is an increasing demand for a remote maintenance notification system for performing remote maintenance using a monitoring device provided in a maintenance target device using the Internet or a public line network.
[0005]
As a conventional technology of such a system, data transmitted from a monitoring target device is accumulated, and an "e-mail with unsent data attached" is periodically transmitted. A local computer (PC) that sends an “e-mail with data attached before that” and the data attached to the received e-mail are transferred using the company intranet, and if the received e-mail is a monthly report or If it is a notification to inform, send a mail server that sends the contents to the email address of the employee or customer, and if a failure is found in the data from this mail server, return an e-mail with a failure notification And a remote monitoring server that sends an e-mail containing a monthly report for the previous month to a mail server. .
[0006]

[0007]
[Problems to be solved by the invention]
However, the above-mentioned conventional system is economical because it is not necessary to keep the line connected all the time because it is transmitted by e-mail. When a mail delay occurs, no information is transmitted, and it cannot be recognized that an error has occurred in the mail system or that a delay has occurred in the e-mail. Therefore, it is a problem as a notification method at the time of occurrence of a serious failure that requires urgent measures.
[0008]
In recent years, computer viruses have been rampant, but their entry routes are mostly via e-mail, and the most frequent infections are caused by opening attached files. It can be prevented to some extent by anti-virus software, but it is a sophistication of the virus. Further, in recent computer viruses, an infected PC sends an e-mail without permission and infects a receiving PC. Since this virus may be transmitted by falsifying the source address based on the information in the infected PC, the recipient may use a known address.
[0009]
In the conventional system, (1) the sender is checked by the address, (2) the attached file is used for data transmission, etc., (3) the opening of the attached file is assumed, and (4) to the customer. Because of the use of attached files in outgoing e-mails, there is a high risk of system virus infection and virus distribution to customers.
[0010]
Therefore, an object of the present invention is to provide a remote maintenance notification system that can respond to an emergency even if the system is abnormal, can prevent computer viruses, and can operate safely.
[0011]
[Means for Solving the Problems]
A feature of the present invention that solves the above object is a remote maintenance notification system that monitors a device to be maintained by a maintenance management device and notifies a monitoring result to a central maintenance device at a remote location. The purpose of the present invention is to report the monitoring result of the target device to the central maintenance device in parallel using an e-mail and a public line.
[0012]
The report is a regular report that is reported at a regular time and a non-regular report that is reported at a time other than the regular time. The non-regular report is that the monitoring result is related to a failure that has occurred in the maintenance target device, or the occurrence of the failure is predicted. Related to the diagnosis required.
[0013]
When reporting the monitoring result to the central maintenance device by e-mail, the maintenance management device reports the e-mail address of the maintenance management device registered in the maintenance management device and the password attached to the subject together with the monitoring result. The central maintenance device is configured to open the e-mail when the central maintenance device is identified from the registered e-mail address and password when the e-mail arrives from the maintenance management device; Performs a process of identifying (recognizing) the maintenance management device that is the notification source from the registered telephone number of the central maintenance device when the notification of the monitoring result arrives from the maintenance management device via the public line.
[0014]
Also, when the report of the monitoring result arrives through the public line, the central maintenance device opens the e-mail and performs a required process based on the monitoring result in the report obtained through the public line when the desired process is not performed. The desired processing is to report the result of monitoring the maintenance target device to a user or an administrator of the maintenance target device.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of a remote maintenance notification system. Reference numeral 1 denotes a maintenance target device 1, which is provided with a temperature sensor 2 and a vibration sensor 3 for monitoring its state. Each of the sensors 2 and 3 is connected to the information processing unit 5 of the maintenance management device 4 installed near the maintenance target device 1. The information transmitting unit 6 is also connected to the information processing unit 5. The maintenance management device 4 is connected to a plurality of maintenance target devices provided with a plurality of sensors. For simplicity of description, one maintenance target device 1 having two sensors 2 and 3 is shown. Was.
[0016]
Reference numeral 31 denotes a maintenance intranet at a remote place for notifying the monitoring result of the maintenance target device 1 from the maintenance management device 4, and includes a mail server 32, a database 37, an alarm information notification PC 44, a diagnosis required information notification PC 45, a periodic information notification PC 46, and an alarm. A mail processing PC 47, a diagnosis required mail processing PC 48, and a regular mail processing PC 49 are connected. Further, the maintenance intranet 31 is connected to the Internet 21 by a router or a gateway function of the server 35, and the Internet 21 is connected to the access point 22. The access point 22 is connected to the maintenance management device 4 and is connected to the e-mail. Receive.
[0017]
Further, the alarm information notification PC 44, the diagnosis required information notification PC 45, and the periodic information notification PC 46 are connected to the maintenance management device 4 via the public lines via the modems 41 to 43, respectively.
[0018]
The maintenance intranet 31 remote from the maintenance management device 4 and the devices 22 to 49 attached thereto constitute a central maintenance device, and the mail server 32 performs virus monitoring of all mails passing therethrough, just in case. Is going.
[0019]
Here, before describing the overall operation, the operation of each device will be briefly described.
First, the operation of the maintenance management device 4 will be described with reference to the flowchart shown in FIG. In addition, the maintenance management device 4 and the central maintenance device are often located in remote places, and in order to improve anti-virus and anti-hacking measures, except for directly collecting data from the equipment 1 to be maintained, only transmission is required, and no e-mail is sent. It is set so as not to receive the data from the public telephone line or the public line, and the upgrade of the software for diagnosis is performed not by remote control but by a service person.
[0020]
From the maintenance management device 4, the regular transmission (regular report) and the irregular transmission (regular report) are sent to the Internet 21 by e-mail, and the information report PCs 44 to 46 are transmitted via a public line. It is performed in parallel before and after.
[0021]
The regular transmission is to periodically transmit data from the temperature sensor 2 and the vibration sensor 3 stored in the maintenance management device 4 at a predetermined time. The irregular transmission is performed when an alarm signal due to an abnormality or failure of the maintenance target device 1 is detected, and when the data of the temperature sensor 2 and the vibration sensor 3 indicate the state of the maintenance target device 1 from the diagnosis required level 0 at which there is no problem, the most dangerous. Among the four classifications up to level 3, which is the state, when the level is determined to be level 1 or higher for the first time and when the level rises, it is transmitted irregularly as an emergency requiring a time other than a predetermined time. .
[0022]
When the apparatus is started up, measurement conditions are set in step (hereinafter abbreviated as S) 51, measurement data for each minute is collected from each sensor 2, 3 of the maintenance target device 1, and recorded in the information processing unit 5. It is recorded and stored in the section (S53). The data such as the time including the above measurement conditions was arbitrarily set as an example. Since the alarm information from the maintenance target device 1 enters irregularly (S52), it is determined whether or not there is an alarm in S54. If there is an alarm, the process proceeds to S55 and the mail address of the maintenance management device 4 which is the transmission source is transmitted as irregular transmission. The alarm information with the password written in the subject is transmitted to the remote central maintenance device. This alarm information has a text, and the text describes the contents of the alarm (monitoring items such as maintenance target equipment and temperature or vibration) and various data (monitoring results) such as the date and time of occurrence. Also, as described later, past data and the like are also attached.
[0023]
Then, as will be described later, if the service person in charge of maintenance performs inspection and repair, the alarms of the maintenance target device 1 and the maintenance management device 4 are released (S57), and the maintenance is restored. The transmission in S55 will be described later in detail.
[0024]
If there is no alarm, the process proceeds to step S58. If one hour has elapsed after confirming the regular recording data interval, the last measured data is recorded and stored in the recording unit of the information processing unit 5 as regular data in step S59. . Then, the process proceeds to S60, in which the stored data and the latest data are used to determine the level from 0 (no need for diagnosis) to 3 by the algorithm for determining the required diagnosis level, but the levels 1 to 3 are determined for the first time. In this case, it is determined that the level is increased in S63, the process proceeds to S64, and the fact that the diagnosis is required and the required diagnostic level are transmitted to the remote central maintenance device side in parallel with the e-mail and the public line as non-regular transmission, It returns to S53.
[0025]
In S60, if it is determined that the diagnosis does not reach the required level, the process proceeds to S61, in which it is determined whether seven days have passed since the last time the steady data was registered. The regular data of the past 21 days is transmitted as scheduled transmission to the access point 22 and the scheduled information reporting PC 46 with the e-mail address of the sender and the password written in the subject so as to be overlapped for 14 days, and the process returns to S53. If it is determined in S61 that seven days have not elapsed, the process returns to S53.
[0026]
If it is not confirmed in S58 that the regular recording data interval of one hour has elapsed, it is determined in S65 whether or not the preset regular transmission time 13:00 has elapsed for the first time in the day. If it has not been determined whether or not the scheduled start has been completed, the e-mail address of the sender (maintenance management device 4) and the password written in the subject are added to the access point 22 and the scheduled information notification PC 46 as scheduled transmission in S67. A periodic call is made and the process returns to S52. If the transmission has been completed in S66, the process returns to S52 as it is, and the above processing is repeated.
[0027]
Next, in S55 of FIG. 2, alarm information is transmitted from the maintenance management device 4, and is received via the access point 22, the Internet 21, the server 35, and via the modem 41, the alarm information reporting PC 44, and the maintenance intranet 31. The operation of the alarm mail processing PC 47 in this case will be described with reference to the flowchart shown in FIG.
[0028]
First, in S71, it is confirmed whether or not an e-mail has been received at the alarm mail address in the mail server 32 (FIG. 1). If it is determined in S72 that the e-mail has been received, the process proceeds to S73, and the sender (maintenance management device) The e-mail address and the password written in the subject of 4) are compared with the data registered in the database 37, and if they match in S78 (if the sender can be confirmed by both the e-mail address and the password), in S74 The detailed information is extracted from the contents of the mail, and in S75, the past data, the history, the customer information and the person in charge are called from the information in the database 37, and in S76, the e-mail is sent to the person in charge of the customer and related persons such as the maintenance manager and the service person. After transmission, a new history is recorded in the database 37 in S77, and the process returns to the reception confirmation in S71.
[0029]
In S78, the e-mail address of the sender (maintenance management device 4) and the password written in the subject are collated with the data registered in the database 37, and if they do not match, it is received in S79 as an e-mail for which security cannot be confirmed. Discard the information and return to S71.
[0030]
The operation of the diagnosis mail processing PC 48 is the same as the operation of the alarm mail processing PC 47. The contents of the mail transmitted to the person in charge of the customer in S76, the person in charge of maintenance, the service person, etc., and the recording in S77. The only difference is what you do.
[0031]
Next, the operation of the regular mail processing PC 49 will be described with reference to the flowchart shown in FIG.
First, in S81, it is checked whether or not the e-mail has been received at the regular mail address in the mail server 32 (FIG. 1). When the reception has been confirmed in S82, the mail address of the sender (maintenance management device 4) is checked in S83. The data registered in the database 37 (FIG. 1) with the password written in the subject is called (recognition processing), and in S88, it is determined that they match, and the sender is recognized as a genuine sender. If possible, steady data is extracted from the contents of the mail in S84, data that is duplicated with the history in the information of the maintenance target device 1 in the database 37 is deleted and recorded in S85, and the process returns to the reception confirmation in S81.
[0032]
In S88, the e-mail address of the sender (maintenance management device 4) and the password written in the subject are collated with the data registered in the database 37, and if they do not match, the process proceeds to S89 as an e-mail for which security cannot be confirmed. Then, the data temporarily stored in the mail server 32 is discarded (89), and the process returns to the reception confirmation (S81).
[0033]
Next, the operation of the diagnosis required information notification PC 45 will be described with reference to the flowchart shown in FIG.
First, in S91, it is checked whether or not the modem 42 for diagnosis needs to be called. If it is determined in S92 that the call has been received, the calling source is notified by a pre-communication information notification service (for example, a number display service) provided by the telephone company. The telephone number of the (maintenance management device 4) is checked (S93). If the telephone number matches with the data registered in the database 37 (S94), if it matches (S94), the process proceeds to S95 and the number of calls required until the call is disconnected is determined. Identify the diagnostic level. Then, in S96, the device to be maintained is recognized from the calling number, and in S97, the history, the information of the person in charge such as the customer representative and the maintenance personnel and the service personnel are extracted from the database 37, and this information has already been notified by mail. If so (S98), the process jumps to S100, records the history in the database, and returns to the incoming call confirmation in S91.
[0034]
If it is determined in S98 that notification has not been made, an e-mail for notifying information is sent to the person in charge, such as a customer representative and a maintenance person or a service person, in S99, and the log is recorded in the database in S100. Return to incoming call confirmation.
[0035]
In the process of FIG. 5, although the diagnosis required level can be recognized, it is unknown which item of the measurement data is targeted, and therefore, the transmitted e-mail is only a notification. Thereafter, an e-mail clarifying which item of the measurement data is the subject or the like is transmitted as confirmation information by the diagnostic mail required PC 48.
[0036]
If the telephone number of the caller (maintenance management device 4) does not match the data registered in the database 37 in S94, after receiving the message, a message urging reconfirmation of the telephone number is played, the call is disconnected, and the call arrives in S91. Return to call confirmation. At this time, it is sufficient to take a measure such as cutting off the code of the sound receiving unit so that no data is accepted for all the modems including the modem 42 for diagnosis required. Also, omitting the operation of receiving and sending a message is omitted, and it is more advantageous in terms of security to disconnect immediately, but the report may be delayed if the callee makes a wrong call again, so in this example, An operation for receiving and sending a message is provided.
[0037]
The processing of the alarm information reporting PC 44 is different from the processing of the diagnosis required information reporting PC 45 in that the modem of the incoming call confirmation S91 is the alarm modem 41, the number of incoming calls is not counted (S95), The only difference is that the notification is not confirmed (S98), and the contents of the e-mail sent to the person in charge of the customer and the related person such as the maintenance person or the service person (S99) are different from the contents of the history record in S100.
[0038]
Next, the processing operation of the scheduled information notification PC 46 will be described in detail with reference to the flowchart shown in FIG.
In step S101, it is checked whether or not the modem 43 has received a call. If the call is determined in step S102, the process proceeds to step S103, where the call originator is provided by a pre-communication information notification service (for example, a number display service) provided by the telephone company. The telephone number of the (maintenance management device 4) is confirmed, and in S104, it is checked against the data registered in the database 37 (FIG. 1). Recognizing the caller, the process proceeds to S108, records the history at a predetermined address in the database 37, and returns to the incoming call confirmation in S101.
[0039]
In S104, if the telephone number of the caller (maintenance management device 4) does not match the data registered in the database 37, after receiving the message, a message urging reconfirmation of the telephone number is flowed, the message is disconnected, and the process proceeds to S101. Return to incoming call confirmation.
[0040]
The regular notification via the modem 43 is for confirming the normal operation of the maintenance management device 4. For example, if there is no report even after the regular transmission time of 2 hours, it is notified that the maintenance management device 4 has failed. Used to report to service personnel.
[0041]
Hereinafter, of the entire operation of the remote maintenance notification system shown in FIG. 1, the operation when an alarm occurs will be described in detail with reference to the flowcharts shown in FIGS.
The maintenance management device 4 monitors the state of the maintenance target device 1 with the sensors 2 and 3, and when alarm information is input (S 52), transmits the alarm information from the information transmission unit 6 as non-regular transmission. In this case, first, an e-mail is transmitted by an Internet connection service of a mobile phone function built in the information transmitting unit 6. For a preset mail address corresponding to the alarm information (here, supposed to be ALARM@****.co.jp), the subject is registered as a password registered in the database 37 (here, supposed to be A1234). Send. The transmission of the e-mail is performed by connecting to the Internet 21 using an access point 22 of an Internet connection contractor contracted in advance or an Internet connection service of a mobile phone company.
[0042]
At this time, the contents of the alarm (monitoring items such as maintenance target equipment and temperature or vibration) and the alarm information (monitoring result) such as the date and time of occurrence are written in the text, and the data recorded in S53 are recorded in S53 so that the situation can be easily grasped. Three hours and the past 21 days of steady data saved in S59 are also attached. The attachment method may be added after the alarm information in the text or attached as a separate file. However, when a separate file is attached, a text data file (* .txt) is not compressed. Good for anti-virus measures.
[0043]
As shown in S71 in FIG. 3, the mail address ALARM @ ****. co. When the alarm mail processing PC 47 monitoring the arrival of the e-mail to the jp confirms the reception of the e-mail from the maintenance management device 4, the e-mail address of the source of the e-mail (the maintenance management device 4) is registered in the database 37 in S73. The maintenance target device is identified by collating with the data that has been set. Subsequently, it is checked whether the subject “A1234” matches the correct password from the database 37 for the specified maintenance target device. If the passwords match, based on the information in the database 37, a mail is sent to the customer representative in which the installation location, date and time of occurrence, status of the maintenance target device, and contact information of the maintenance personnel and the sales personnel are entered. For maintenance personnel, maintenance managers, sales personnel, and service personnel, the maintenance personnel is the destination (TO) and the others are broadcasters (CC). An e-mail with the contact information of the maintenance staff, the contact information of the sales staff, the contact information of the customer staff, the past 3 hours of data recorded in S53, and the past 21 days of steady data saved in S59 is sent, and sent to the database. And the history of the transmission destination is recorded (S74 to S77). Note that the subject of this transmission or recording is “alarm information (detailed information)” instead of the password “A1234”.
[0044]
In the above description, one type of password is used for each device to be maintained. For example, it is determined that a fixed password “A1234” is added to the time for sending the mail (20 for 20:12). In this case, a plurality of passwords may be changed according to a predetermined rule in the database 37 and the maintenance management device 4 as in the case where “A1254” is used as a password.
[0045]
In S55 of FIG. 2, two calls are made using the mobile telephone function of the information transmitting unit 6 with the telephone number (here, supposed to be ####-####-0001) to call the alarm modem 41. Call. If the alarm modem 41 cannot make a call during reception or the like, it tries to reconnect until two calls can be made at one minute intervals.
[0046]
As shown in FIG. 5, the alarm PC 44 monitoring the incoming call to the telephone number ####-####-0001 of the alarm modem 41 transmits the call from the maintenance management device 4 in S91. After confirmation, the telephone number of the caller who obtained the pre-communication information notification service is compared with the data registered in the database 37, and the device to be maintained is specified.
[0047]
If it is confirmed from the information in the database 37 that the alarm information via e-mail has not been input and has not been notified for the maintenance target device 1 (S98), the maintenance person is notified to the customer representative based on the information in the database 37. Send an e-mail with the location of the equipment, the date and time the information was received, and the contact information for the maintenance and sales representatives. If it is confirmed that alarm information via e-mail has been input for the maintenance target device 1 and has been notified (S98), only the history of incoming calls is stored in the database 37 in S100 and transmitted by e-mail. Is not performed.
[0048]
In S99, for the maintenance person, the maintenance system administrator, the sales person, and the service person, the maintenance person is set as the destination (TO) and the others are set as the broadcaster (CC). An e-mail containing the date and time, contact information of the maintenance person, the contact person of the customer and the sales person is transmitted, and the transmission date and the history of the transmission destination are recorded in the database.
[0049]
The subject at this time is “alarm information (first report)”.
[0050]
In this system, the alarm information (first report) may be omitted depending on the information reception timing. However, since the (detailed information) includes the contents of (first report), there is no practical problem.
[0051]
In addition, the alarm information is transmitted in parallel with the occurrence of an emergency through e-mail and the public line, and the source of the alarm is double-checked. Since the device is discarded, the safety of the system can be ensured, and the maintenance target device can be surely monitored.
[0052]
As for the transmission of the alarm information, it is preferable that the e-mail is transmitted first as described above, and then the transmission is performed using the public (telephone) line. However, even if the order is changed, almost the same effect is obtained. .
[0053]
Next, the operation of transmitting the diagnosis required information in the overall operation of the remote maintenance notification system shown in FIG. 1 will be described with reference to the flowcharts shown in FIGS.
In S60 to S63 in FIG. 2, if the diagnosis level 1 is determined for the first time by a preset algorithm for determining the diagnosis level based on the measurement data of the temperature sensor 2 and the vibration sensor 3, the diagnosis is required in S64. Information is transmitted from the information transmitting unit 6.
[0054]
The information transmitting section 6 has a built-in mobile phone function. First, a subject is input to a preset mail address corresponding to the diagnosis required information (here, supposed to be SHINDAN@****.co.jp). The password is transmitted as a password registered in the database 37 (here, temporarily assumed to be B5678). The transmission of the e-mail is performed by connecting to the Internet 21 using an access point 22 of an Internet connection contractor contracted in advance or an Internet connection service of a mobile phone company.
[0055]
At this time, in the same manner as the operation at the time of the alarm occurrence, the main body is filled with necessary diagnosis information such as the process of determining that the diagnosis is required and the date and time of occurrence, and the past three hours of data recorded in S53 and the regular data stored in S59. Attached for 21 days. The attachment method may be added after the alarm information in the text or attached as a separate file. However, when a separate file is attached, a text data file (* .txt) is not compressed. Good for anti-virus measures.
[0056]
As described above, the diagnostic mail processing PC 48 that performs the same processing as the alarm mail processing PC 47 shown in FIG. 3 includes the alarm mail address SHINDAN @ ****. co. jp, the arrival of a mail requiring diagnosis from the maintenance management device 4 is confirmed (S71 to S72). The mail address of the mail sender is collated with the data registered in the database 37, and the maintenance target device is specified. Subsequently, it is checked from the database 37 for the specified maintenance target device whether the subject “B5678” matches the correct password. If the passwords match, the contents of the e-mail are checked, and based on the information in the database 37, the location of the equipment to be maintained, the date and time of occurrence, the status, and the contact information of the maintenance personnel and the sales representative are entered for the customer representative. send an email. For maintenance personnel, maintenance managers, sales personnel, and service personnel, the maintenance personnel is the destination (TO) and the others are broadcasters (CC). E-mail with the contact information of the maintenance staff, the contact information of the sales staff, the contact information of the customer staff, and the past 3 hours of data recorded in S53 and the past 21 days of steady data saved in S59 is sent to the database. The date and the history of the transmission destination are recorded (S74 to S77). Note that the subject at this time is not the password “B5678”, but “diagnosis information (detailed information)”.
[0057]
The maintenance management device 4 transmits the telephone number to be called to the diagnosis-required modem 42 by using the mobile phone function of the information transmission unit 6 after the transmission of the diagnosis required information by e-mail in S64 of FIG. ##-####-0002) also make two calls to transmit the diagnostic level 1 required. At this time, if the diagnosis required level is 2, the call is 5 calls, and if it is 3, the call is 8 calls. If a call cannot be made during the reception of the modem 42 for diagnosis or the like, reconnection is attempted until two calls can be made at one-minute intervals.
[0058]
As shown in FIG. 5, the diagnostic PC 45 monitoring the incoming call to the telephone number ####-####-0002 of the diagnostic modem 42 transmits the call from the maintenance management device 4. When confirmed, the telephone number of the caller who obtained the pre-communication information notification service is compared with the data registered in the database 37, and the caller is specified as the maintenance management device 1. Then, since there are two calls at the same time, it is recognized that the diagnostic level required is 1.
[0059]
When it is confirmed from the information in the database 37 that the diagnosis-required information via the e-mail has not been input and the notification has not been made for this maintenance target device 1 (S98), the customer representative is informed of the maintenance target device 1 based on the information in the database 37. Send an e-mail with the installation location of the equipment, the date and time the information was received, and the contact information of the maintenance and sales personnel. For maintenance personnel, maintenance system administrators, sales personnel, and service personnel, the maintenance personnel is the destination (TO) and the others are broadcasters (CC). An e-mail containing the contact level of the diagnosis required level, the maintenance staff, the customer staff and the sales staff is transmitted, and the transmission date and the history of the transmission destination are recorded in the database (S99 to S100). Note that the subject at this time is “diagnosis information required (first report)”.
[0060]
Even if the transmission of the information requiring diagnosis is not as large as the transmission of the alarm information, the maintenance target device 1 may cause a failure in the future, and is transmitted at an undefined time.
