Web server of connection processing unit 22, internal database 23 for storing dynamic data acquired from work machine 11 through communication means and related data related to the dynamic data, and management server for managing internal database 23 And an external various information database 43 storing related data to be stored in the internal database 23, and a management server for managing the external various information database 43, the web of the data connection processing unit 22 The server retrieves the related data from the external information database 43 connected to itself and retrieves the internal data. The dynamic data (operation data and warning information, etc.) stored in the internal database 23 together with related data (customer information) related to the dynamic data (customer information). The data format of data exchange via the web server is set to an XML data format, and at least the web server functions as a service requester, and each server connected to the web server functions as a service provider.

  The management system of the management unit 15 is a technology that uses a so-called XML web service for the work machine remote operation management system 10 of the work machine 11. The XML web service is exchanged on the network by data exchange in the XML data format. A technology that links scattered applications. XML (eXtensible Markup Language) is one of the markup languages, and the biggest feature is that it is a language that can send and receive data between systems without depending on the platform of each system, and that the program can interpret. It can be used to send and receive data between servers.

  SOAP (Simple Object Access Protocol) is known as a communication protocol that can use an object in XML data format via a network (HTTP or the like that is generally used as a lower protocol can be used). Therefore, for example, in the network environment connected by HTTP, using SOAP, for example, by sending the XML data from the first server to the second server on the network, the second server performs processing, and after the processing The XML data can be returned to the first server, and if the website is operated by the first server, the acquired data can be reflected on the website.

  The service requester and the service provider are both concepts on the XML web service. The service requester is a source of XML data for requesting data (for example, the first server), and the service provider is the transmission of the data. A partner server that is the destination and performs processing described in the data and then returns the processed data to the service requester (for example, the second server).

  In the management unit 15, the web server of the data connection processing unit 22 functions as a service requester, and the management servers of the internal and external databases 23 and 43 connected thereto function as service providers. Therefore, the XML data format from the web server Each management server processes the command based on the command data, and returns the processed data to the web server. If the returned data is related data from the external information database 43, the web server transmits it as it is to the management server of the internal database 23 and stores it. If the returned data is dynamic data (operation data, warning information, maintenance information, etc.) from the internal database 23 and related data (customer information) attached to it, the web server will go to the website operated by itself. To reflect.

  Therefore, in this device, for example, when a customer or a service person wants to know the dynamic data of the work machine 11 owned or in charge, he / she accesses the website of the management unit 15 from his / her terminal and instructs the data acquisition request. Can be put out.

  In response to this instruction, the web server of the management unit 15 transmits the command data in the XML data format to the management server of the internal database 23. Therefore, the management server sends the XML of the desired work machine from the internal database 23. While taking out the dynamic data in the data format, the related data is also taken out and sent back to the web server. In the web server, dynamic data and related data are added to the web site and reflected on the website. Thereby, a customer or a service person can acquire dynamic data together with related data. When a customer or a service person connects his / her own database to his / her terminal, the dynamic data acquired from the website is in the XML data format, and can be directly imported into the database.

  Data exchange between the work machine 11 and the management unit 15 is also performed in the XML data format, and the work machine side data acquisition means is caused to function as a service provider. The software rewriting system 42, the repair service system 44, the rental system 45, and the instruction acquisition intranet network 46 that exchange data with the web server of the data connection processing unit 22 in the XML data format are the same as the various information databases 43. To act as a service provider.

  As described above, the application on the management unit 15 side in the work machine remote operation management system 10 uses the XML data format as the data format for data exchange with the web server of the data connection processing unit 22, and at least the web server is a service requester. In addition, since each server connected to the web server is made to function by the service provider, the dynamic data and the related data returned from the service provider are also in the XML data format. In addition, it is easy for the customer side or an external system to capture the data as it is via a web server.

  In other words, it is compatible with the XML data format, which is a standard format in the construction industry, and this XML data format is also a universal data format that extends to the whole world. Can pass. Furthermore, depending on the mode, it is possible to connect to an external system and allow the web server of the data connection processing unit 22 to function as a service requester so that the dynamic data acquired by the web server is directly taken into the external system. Is possible.

  Further, it is easy to increase the number of servers as service providers connected to the website of the management unit 15, and in this case, it is possible to increase the processing of the management system itself. On the other hand, since it is sufficient for the web server of the data connection processing unit 22 to function as a service requester, the burden on the management unit itself does not increase, and the effect of upgrading the apparatus at a low cost can be obtained while the mechanism is simple.

  That is, for system construction, it is not necessary to create each system configuration including cooperation with other systems as in the past, and only one web service of the cooperation connector, that is, the data connection processing unit 22, is created. Various other systems such as a software rewriting system 42, various information databases 43, a repair business system 44, a rental system 45, an intranet network 46 for obtaining instructions, and their web services 42ws, 43ws, 44ws, 45ws , 46ws can be easily linked, so it is easy to connect with each original interface and can be created at low cost.

  Furthermore, it is easy to add or modify another system after the work machine remote operation management system 10 is completed. For example, a software rewriting system 42, various information databases 43, a repair business system 44, a rental system 45, and an instruction acquisition intranet. Even if other systems such as the network 46 are linked, it is not necessary to develop a system for putting these other systems in the work machine remote operation management system 10, and the web services 42ws, By simply attaching 43ws, 44ws, 45ws, 46ws, another system can be added.

The management unit 15 that has received the operation data reflects the operation data on the website and provides information to the customer or service person.

  Next, the arithmetic processing unit 61 confirms the presence or absence of warning information in the spontaneous transmission data storage unit 72 of the storage unit 62, and if there is warning information, extracts the data and transmits the data from the wireless communication unit 64 to the management unit 15. .

  The management unit 15 that has received the warning information reflects the data on the website, and the electronic information to the effect that the warning information has been received on the mobile phone 17ph, 19ph of the customer or service person registered on the management unit 15 side. send mail.

  The arithmetic processing unit 61 forcibly disconnects the line when a predetermined time has elapsed after each data transmission. If there is no e-mail for calling from the management unit 15, the arithmetic processing unit 61 always checks whether there is warning information in the spontaneous transmission data storage unit 72 of the storage unit 62, and if there is data, The wireless communication unit 64 makes a call to the management unit 15 to transmit warning information.

  Next, an actual data flow including the customer and the service person of the work machine remote operation management system 10 will be described.

  When customers and in-house (including dealers) service personnel want to know the current operating status of their own or in charge of the work machines 11 they are in charge of, the customer's terminal equipment 17 or the in-house terminal equipment 19 can connect to the Internet network 16. Alternatively, after accessing the website operated by the management unit 15 via the intranet network 18 and logging in with an ID and a password, the operation data of the desired work machine 11 is requested to be acquired.

  On the management unit 15 side, the requested access data to the desired work machine 11 is obtained from its own database 23, and on the basis of the data, a call e-mail is sent to the desired work machine 11 via the wireless carrier network 14. Send.

  On the other hand, on the work machine 11 side, the call e-mail is received by the wireless communication unit 64 of the dynamic management controller 26. When the arithmetic processing unit 61 of the activity management controller 26 confirms the saving of the calling e-mail, it outputs a call command to the radio communication unit 64, and the management unit via the radio carrier network 14 including the mobile phone communication network Call the 15th side.

  Upon receiving the call, the management unit 15 side outputs an operation data request signal. Upon receiving this, the work machine 11 side receives a desired operation from the storage unit 62 in the dynamic management controller 26. Data is acquired and output from the wireless communication unit 64. Upon receiving this data, the management unit 15 side temporarily stores it in its own database 23 and reflects it on its own website in a predetermined output format. As a result, the desired operation data at that time is displayed on the customer terminal device 17 or the in-house terminal device 19.

  In this data flow, the dynamic management controller 26 of the work machine 11 obtains power directly from the battery of the work machine 11 even when the engine key switch is off, and operates as long as the main power switch is not turned off. Even when the work machine 11 is not operating, it is in a posture to constantly monitor and respond to the e-mail for calling from the management unit 15 side, so unless the main power switch is turned off, the customer or in-house (dealer) Can request and obtain real-time operational data on the desired work machine 11 at any time through the website operated by the management unit 15.

  As for the warning information, if it is stored in the spontaneous transmission data storage unit 72, as long as the main power switch is on, the warning information is immediately transmitted from the work machine 11 side to the management unit 15 side, and the customer terminal device is transmitted by e-mail. 17 or in-house terminal device 19, it is possible to know in real time that the work machine 11 is abnormal.

  In particular, using the GPS position information acquired through the position measuring unit 65 of the movement management controller 26, the assumed area where the operating position of the work machine 11 is set in relation to the date and time managed by the date management unit 66 is used. When the work machine 11 moves outside, if the position information is stored as warning information, the customer or serviceman can immediately determine whether or not it is stolen in a remote place. In the case of position information that can be assumed to be highly likely to be stolen, an engine start restriction function such as the airframe control controller 30 shutting off the engine start circuit by itself based on a warning signal from the dynamic management controller 26. By providing, it is possible to prevent theft.

  In addition, all the operation data requests from the customer terminal device 17 or the in-house terminal device 19 are routed through the management unit 15, so that the work machine 11 only sends the operation data to the management unit 15. Since the start of the data transmission is limited to the presence or absence of an e-mail for calling from the management unit 15, the work machine 11 has no need for the customer authentication mechanism for passing the data, and has been accessed. Instead of handing over data sometimes, the call is terminated by the call, and then the work machine 11 side and the management unit send data to the management unit 15 to which the connection destination is set from the work machine 11 side. Both 15 have a simple system configuration and there is no risk of data leakage.

  That is, in this work machine remote operation management system 10, the destination of the dynamic data from the work machine 11 side is only the management unit 15 to which contact information is set in advance, and the customer terminal device through the website from the management unit 15 Since the data is provided to the terminal device 19 or the in-house terminal device 19, if the dynamic data is provided only to the management unit 15 on the work machine 11 side, the data can be provided to a plurality of customers or service personnel.

  This is because the work machine 11 can be accessed directly from a plurality of customer terminal devices 17 or in-house terminal devices 19 and the system can be simplified as compared with a system that provides data to the work machine 11 because no individual authentication mechanism is required. At the same time, the communication run cost can be kept low. In addition, data exchange with the work machine 11 is limited to the management unit 15 for which contact information is determined in advance, and since data flows through a limited line, the risk of information leakage is greatly reduced, and security is improved. The construction cost required for this is extremely low.

  In addition, since the management unit 15 performs batch transmission / reception of data with the work machine 11 and reflects the received data on the website and provides it to the customer or service person, for example, only raw data from the work machine 11 Even if it is only received, at the stage of reflecting it on the website, raw data of only numerical values can be processed and displayed in the format desired by the customer or service person, and the system is suitable for the convenience of the customer or service person ing.

  In other words, when the management unit 15 performs the data exchange in a batch, the management unit 15 can sort out the operation data of the work machine 11 that is necessary for maintenance management and that required by the customer. Only necessary data can be provided for each of the customer and the service person. Furthermore, it is possible for the management unit 15 side to collect the operation data of all work machines at a fixed time and reflect the data on the website. Can be inexpensive.

  In this way, the operation information and position information of the work machine 11 are transmitted from the work machine 11 by wireless communication, and the operation information and position information received by the management unit 15 are converted into customer terminals at a plurality of bases as shown in FIG. As shown in FIG. 1, in the work machine remote operation management system 10 that is accessed and acquired from the device 17 by a plurality of IDs 81, 82, and 83 as individual identification codes respectively registered corresponding to each base.
