<Processing of construction machine management system>
FIG. 4 is a flowchart for explaining an example of the processing operation of the construction machine management system. Hereinafter, an example of the processing operation of the construction machine management system will be described with reference to FIG. The construction machine management system 1 transmits the scheduled work information and the authentication information from the management terminal 8 to the portable terminal 3 as step S12. That is, the management terminal 8 can send the scheduled work information to the portable terminal 3 of the worker who performs the predetermined work scheduled by operating the construction machine 2 and can drive the construction machine 2 that executes the work. To send authentication information. The mobile terminal 3 stores the scheduled work information and authentication information sent from the management terminal 8 in the storage unit 56.

  Here, when the portable terminal 3 receives the scheduled work information, the worker identifies the target construction machine 2 based on the received scheduled work information, and connects the portable terminal 3 to the identified construction machine 2. Specifically, the portable terminal 3 is fixed to the attachment device 30 and the connection terminal 22 and the connection terminal 52 are connected. When the construction machine management system 1 detects that the construction machine 2 and the portable terminal 3 are connected, the construction machine management system 1 performs a connection process between the portable terminal 3 and the construction machine 2 in step S14. Specifically, the construction machine management system 1 performs ID exchange, communication method setting, and the like between the vehicle body control unit 24 and the terminal control unit 54 via the connected connection terminal 22 and connection terminal 52. It is assumed that both can communicate.

  When the connection process is performed in step S14, the construction machine management system 1 performs an authentication process using the construction machine 2 and the portable terminal 3 in step S16. Here, the authentication process is a process for determining whether the authentication information acquired by the mobile terminal 3 in step S12 matches the authentication information stored in the construction machine 2. FIG. 4 shows the processing when the authentication information matches, but when the authentication information does not match, the processing after step S16 is not performed.

  The construction machine management system 1 performs an authentication process in step S16, and when the authentication information matches, the construction machine 2 performs a drive unit (a portion for driving the traveling body 12 and the work implement 14, a drive source and a drive control unit) in step S18. The activation process of 16) is performed.

  When the construction machine 2 activates the drive unit in step S18, the construction machine management system 1 executes the operation in step S20. The work here is work performed by the operator operating the construction machine 2 and is basically work based on scheduled work information stored in the mobile terminal 3.

  When the work executed in step S20 is completed, or when an end instruction is input from the worker, the construction machine management system 1 executes a drive unit stop process in the construction machine 2 in step S22. The stop process is a state in which the drive unit (the portion that drives the traveling body 12 and the work implement 14, the drive source and the drive control unit 16) of the construction machine 2 is not driven.

  When the construction machine management system 1 performs the stop process in step S22, the execution work content is transmitted from the portable terminal 3 to the management terminal 8 in step S24. That is, the mobile terminal 3 compares various information including information acquired by the sensors 20 and 46 at the time of execution of work with planned work information, and stores the work contents executed by the construction machine 2. The stored information is sent to the management terminal 8 as execution work contents.

  After performing the process of step S24, the construction machine management system 1 performs a process of releasing the connection between the portable terminal 3 and the construction machine 2 as step S26. That is, processing is performed so as not to perform wired communication between the mobile terminal 3 and the construction machine 2 via the connection terminal 22 and the connection terminal 52. The construction machine management system 1 ends this process after performing the process of step S26.

  The construction machine management system 1 may execute the process of step S24 and the process of step S26 in the reverse order. Further, the process of physically releasing the contact between the connection terminal 22 and the connection terminal 52 executed by the operator may be executed any time after the process in step S22 is completed. The construction machine management system 1 performs the process of disconnecting communication in step S26 between the construction machine 2 and the portable terminal 3 even when the connection terminal 22 and the connection terminal 52 are physically connected. Communication can be suppressed.

<Processing of construction machinery>
5 and 6 are flowcharts for explaining an example of the processing operation of the construction machine. Hereinafter, an example of the processing operation of the construction machine will be described with reference to FIGS. 5 and 6.

  First, the process shown in FIG. 5 will be described. The process shown in FIG. 5 is repeatedly executed when the portable terminal 3 is not connected to the construction machine 2 or when the drive unit (the traveling body 12 and the work implement 14) of the construction machine 2 is not driven. The vehicle body control unit 24 of the construction machine 2 determines whether or not the portable terminal 3 is connected in step S102, that is, whether or not it is connected to the terminal control unit 54 via the connection terminal 22 and the connection terminal 52. The vehicle body control part 24 complete | finishes this process, when it determines with no connection (No) by step S102. The vehicle body control unit 24 repeats this process until it is connected to the mobile terminal 3.

  If the vehicle body control unit 24 determines that there is a connection (Yes) in step S102, the vehicle body control unit 24 starts communication in step S104. In other words, the vehicle body control unit 24 performs the connection process of S14 described above to be in a state where communication with the terminal control unit 54 of the mobile terminal 3 is possible. The vehicle body control part 24 will perform an authentication process as step S106, if communication is started by step S104. Specifically, the authentication information held by the terminal control unit 54 and the authentication information read from the storage unit 26 are collated. Here, the verification process can be performed by the vehicle body control unit 24 to improve security. In the present embodiment, the matching process is executed by the vehicle body control unit 24, but may be executed by the terminal control unit 54.

  After performing the authentication process in step S106, the vehicle body control unit 24 determines whether the authentication is permitted, that is, whether the authentication information matches in step S108. If the vehicle body control unit 24 determines that the authorization is not permitted (No) in step S108, that is, the authentication information does not match, an error is notified as step S110. That is, the vehicle body control unit 24 sends an error message indicating that the authentication information does not match to the terminal control unit 54 and ends this process. When the authentication information does not match, the vehicle body control unit 24 notifies the error and terminates the process, thereby terminating the process without operating the traveling body 12 and the work implement 14. That is, the vehicle body control unit 24 prohibits the traveling body 12 and the work implement 14 from operating when the authentication information does not match.

  The vehicle body control part 24 notifies permission as step S112, when it determines with permission in step S108 (Yes), ie, authentication information corresponds. That is, the vehicle body control unit 24 sends information indicating that the authentication information matches to the terminal control unit 54 as permission information.

  When notifying permission in step S112, the vehicle body control unit 24 determines whether there is an activation instruction in step S114, that is, whether the activation instruction is transmitted from the terminal control unit 54. If the vehicle body control unit 24 determines that there is no activation instruction (No) in step S114, the process proceeds to step S114. That is, the vehicle body control unit 24 repeats the process of step S114 until the activation instruction is detected.

  When it is determined in step S114 that the activation instruction is present (Yes), the vehicle body control unit 24 executes the activation operation in step S116. Here, the starting operation is a process of making the traveling body 12 travelable by the drive control unit 16 and making the work implement 14 operable. For example, it is an engine start operation and a hydraulic pump start operation. The vehicle body control part 24 will complete | finish this process, if a starting operation is performed by step S116. After the start-up operation, the vehicle body control unit 24 drives the traveling body 12 and the work implement 14 on the basis of instructions input from the respective units and performs work.

  Next, the operation at the time of driving the vehicle body control unit 24 will be described with reference to FIG. The vehicle body control unit 24 determines whether there is a control instruction in step S120. The control instruction is an instruction input by the vehicle body control unit 24 based on an operation input to the operation unit 18 by the operator or a detection value detected by the sensor 20, or an instruction input from the terminal control unit 54.

  When it is determined in step 120 that there is a control instruction (Yes), the vehicle body control unit 24 executes the operation instructed as step S122. That is, each part of the construction machine 2 is operated based on the instruction detected in step S120. If the vehicle body control unit 24 determines that there is no control instruction (No) in step S120, the process proceeds to step S124.

  When it determines with No by step S120, or when the process of step S122 is performed, the vehicle body control part 24 will determine whether vehicle information is transmitted to the terminal control part 54 as step S124. Here, the vehicle information is various information of the construction machine 2 such as a detection value detected by the sensor 20 and a value calculated based on an instruction generated by the drive control unit 16 and the vehicle body control unit 24. Specifically, there are water temperature, oil temperature, fuel amount, type and number of warnings, maintenance information, arm crane information, work amount, work mode, and the like.

  If it is determined in step S124 that the vehicle information is to be transmitted (Yes), the vehicle body control unit 24 acquires the vehicle information in step S126, and transmits the vehicle information to the terminal control unit 54 in step S128. The vehicle body control part 24 complete | finishes this process, if the process of step S128 is performed. The vehicle body control part 24 complete | finishes this process, when it determines with not transmitting vehicle information by step S124 (No).

  Note that, when the authentication information matches, the vehicle body control unit 24 of the present embodiment determines whether there is an activation instruction. Specifically, the vehicle body control unit 24 accepts an input of the activation instruction in a state where the activation operation can be performed. However, it is not limited to this. When the authentication information matches, the construction control unit 24 can execute an operation based on various operations including an activation instruction. In addition to the operation for starting the traveling body 12 and the work implement 14, the activation operation includes various activation operations such as an instrument activation operation, a light illumination operation, a monitor illumination operation, and the like.

  First, the process shown in FIG. 7 will be described. The process shown in FIG. 7 is executed when the mobile terminal 3 is not connected to the construction machine 2. The terminal control unit 54 of the portable terminal 3 receives the scheduled work information and the authentication information as step S202. Note that the mobile terminal 3 is automatically sent from the management terminal 8 even if it receives the scheduled work information and the authentication information by accessing the management terminal 8 based on the operation input to the operation unit 42 by the worker. Scheduled work information and authentication information may be received.

  When the terminal control unit 54 receives the information in step S202, it determines in step S204 whether there is a connection with the construction machine 2, that is, whether it is connected to the vehicle body control unit 24 via the connection terminal 22 and the connection terminal 52. . If the terminal control unit 54 determines that there is no connection (No) in step S204, the terminal control unit 54 proceeds to step S204. After receiving the information, the terminal control unit 54 repeats the process of step S204 until connected to the construction machine 2.

  If it is determined in step S204 that there is a connection (Yes), the terminal control unit 54 starts communication as step S206. That is, the terminal control unit 54 performs the connection process of step S14 in FIG. 4 described above to be in a state where communication with the vehicle body control unit 24 of the construction machine 2 is possible. After starting communication in step S206, the terminal control unit 54 transmits authentication information in step S208. Specifically, the terminal control unit 54 transmits the authentication information acquired in step S202 to the vehicle body control unit 24.

  After transmitting the authentication information in step S208, the terminal control unit 54 determines whether there is a permission notification in step S210, that is, whether information indicating that the authentication information matches is received. If it is determined in step S210 that there is no permission notification (No), the terminal control unit 54 determines in step S212 whether there is an error notification, that is, whether information indicating that the authentication information does not match is received. If the terminal control unit 54 determines in step S212 that there is no error notification (No), the terminal control unit 54 proceeds to step S210. In this way, the terminal control unit 54 repeats the processes of step S210 and step S212 until receiving either a permission notification or an error notification. If the terminal control unit 54 determines that there is an error notification (Yes) in step S212, the terminal control unit 54 ends this process. That is, when the authentication information does not match, the terminal control unit 54 ends the process without shifting to the driving process of the construction machine 2. Thereby, the construction machine 2 is in a stopped state.

  If it is determined in step S210 that there is a permission notification (Yes), the terminal control unit 54 determines whether there is a startup operation in step S214. The terminal control unit 54 determines that there is an activation operation when a predetermined operation is input to the operation input to the operation unit 42 or when a preset condition is satisfied.

  If the terminal control unit 54 determines in step S214 that there is no activation operation (No), the terminal control unit 54 proceeds to step S214. The terminal control unit 54 repeats the process of step S214 until there is an activation operation. If the terminal control unit 54 determines in step S214 that there is an activation operation (Yes), in step S216, the terminal control unit 54 transmits an activation instruction based on the activation operation to the vehicle body control unit 24, and ends this process. The terminal control unit 54 can start the construction machine 2 by transmitting a start instruction to the vehicle body control unit 24.

  Next, the operation at the time of driving the terminal control unit 54 will be described with reference to FIG. The terminal control unit 54 determines whether there is a control operation in step S220. The control instruction is an instruction created based on an operation input to the operation unit 42 by the operator or a detection value detected by the sensor 46.

  If it is determined in step 220 that there is a control operation (Yes), the terminal control unit 54 transmits a control instruction created based on the control operation in step S222 to the vehicle body control unit 24, and proceeds to step S224. If the terminal control unit 54 determines that there is no control operation (No) in step S220, the terminal control unit 54 proceeds to step S224.

  When it is determined No in step S220 or when the process of step S222 is executed, the terminal control unit 54 has new vehicle information as step S224, that is, new vehicle information sent from the vehicle body control unit 24. Determine whether.

  If it is determined in step S224 that vehicle information is present (Yes), the terminal control unit 54 processes the vehicle information as step S226, stores the vehicle information in the storage unit 56, and proceeds to step S228. When it is determined in step S224 that there is no vehicle information (No), the terminal control unit 54 acquires the detection result of the sensor 46 as step S228. Note that the terminal control unit 54 acquires a detection value necessary for creating a work content to be described later among the detection results of the sensor 46.

  After acquiring the detection result of the sensor 46 in step S228, the terminal control unit 54 determines whether the connection with the construction machine 2 is released in step S230. If the terminal control unit 54 determines in step S230 that the connection has not been released (No), the terminal control unit 54 proceeds to step S236. If the terminal control unit 54 determines in step S230 that the connection is released (Yes), the terminal control unit 54 acquires information as step S232. In addition, when it is determined that the connection with the mobile terminal 3 is released, the construction machine 2 preferably stops the traveling body 12 and the work machine 14. Here, the terminal control unit 54 executes various processes based on an operation input to the operation unit 42 by the worker, and acquires information. For example, an image is taken by the camera 48 and an image to be worked is acquired.

  After acquiring information at step S232, the terminal control unit 54 determines whether it is connected to the construction machine 2 at step S234. If it is determined that the terminal control unit 54 is not connected to the construction machine 2 (No), the terminal control unit 54 proceeds to step S232 and acquires information. If the terminal control unit 54 determines that the construction machine 2 is connected (Yes) in step S234, the process proceeds to step S236.

  The terminal control part 54 performs an analysis process as step S236, when it determines with No by step S230, or when it determines with Yes by step S234. The analysis process is a process of analyzing the vehicle information acquired in step S226, the detection result of the sensor 46 acquired in step S228, and the information acquired in step S232, and specifying the work content executed by the construction machine 2. After executing the analysis process in step S236, the terminal control unit 54 updates the work content based on the analysis result in step S238, and ends this process. The terminal control unit 54 repeatedly executes the process shown in FIG. 8 when the construction machine 2 is driven, and transmits the created work content to the management terminal 8 when the driving of the construction machine 2 is finished as described above.

  As described above, the construction machine management system 1 enables the construction machine 2 to operate on the condition that the authentication information stored in the portable terminal 3 matches the authentication information stored in the construction machine 2. That is, the security of the construction machine 2 can be increased by using information transmitted and received by the mobile terminal 3 as a key. That is, by using the portable terminal 3 that can be specified by the owner as a key, it is possible to accurately grasp which worker has been given authentication information as a key.

  In addition, the worker can start the construction machine 2 by connecting the portable terminal 3 to the construction machine 2 after storing necessary information in the portable terminal 3 by downloading from the management terminal 8. . As a result, the operator does not need to remember a password or the like, and the operability can be improved.

  Further, the manager who manages the construction machine 2 can manage the information of the plurality of construction machines 2 at once by managing the authentication information with the management terminal 8. Further, by operating the management terminal 8, the authentication information can be provided to the portable terminal 3 of the necessary worker.

  Note that the authentication information is preferably information in which the content of the authentication information changes every time work is performed. Thus, by creating authentication information as changing information, the authentication information can be used as authentication information that can be used only for a predetermined time. Thereby, the worker who has acquired the authentication information can be prevented from driving the construction machine 2 except for the permitted time, and the security can be further improved.

  In the above embodiment, it is determined whether the authentication information matches at the time of activation (authentication processing). However, the authentication information may be periodically executed every set time. By periodically executing the authentication process, the work can be stopped when the work is performed beyond the permitted work time.

  Moreover, it is preferable that the construction machine management system 1 uses a part of the scheduled work information in addition to the authentication information for the authentication process. For example, the construction machine management system 1 and the construction machine 2 use the information on the work date and time stored in the scheduled work information, and in addition to the above-described authentication information that is a password, the time information for using the construction machine 2 is one. If it does, the construction machine 2 can be driven. Thereby, security can be made higher.

<Other processing operations>
Moreover, it is also preferable that the construction machine management system 1 determines whether the construction machine 2 can be driven based on the scheduled work information and the position information. Here, FIG. 9 is a flowchart for explaining an example of the processing operation of the mobile terminal. In step S250, the terminal control unit 54 acquires its own position information by the GPS unit 50, and acquires work conditions in step S252. The terminal control unit 54 can acquire the work condition by analyzing the scheduled work information. The terminal control unit 54 acquires information on an area where the work included in the scheduled work information is executed as the work condition.

  When the terminal control unit 54 obtains the work condition in step S252, it determines whether it is within the permitted area as step S254. That is, the terminal control unit 54 determines whether or not the position information acquired in step S250 is included in an area (permitted area) for executing the work acquired in step S252.

  If the terminal control unit 54 determines in step S254 that it is within the permitted area (Yes), in step S256, the terminal control unit 54 continues the operation, that is, leaves the process as it is, and ends this processing. If the terminal control unit 54 determines in step S254 that it is not within the permitted area (No), the terminal control unit 54 executes work stop processing in step S258. Here, the work stop process is a state in which driving of the traveling body 12 and the work implement 14 is stopped. Note that traveling toward the set area may be possible. By making it possible to travel with conditions, it is possible to reduce the risk of suddenly stopping on the road or becoming incapable of moving on the road. If the terminal control unit 54 executes the work stop process in step S258, the terminal control unit 54 ends this process.

  The construction machine management system 1 uses the function of the GPS unit 50 of the portable terminal 3 in this way, restricts the area where the construction machine 2 can be driven, that is, provides a geofence, so that the construction machine 2 is stolen. Even in such a case, the moving range of the construction machine 2 can be limited. Thereby, the security of the construction machine 2 can be further improved.

  In the above embodiment, driving is limited. However, when it is determined that it is not in the permitted area, a warning (sound, flash, vibration) may be issued.

  In addition, the construction machine management system 1 makes the portable terminal 3 and the construction machine 2 each owned by the worker detachable, so that the worker can acquire the authentication information as necessary, and the worker himself It becomes possible to drive a plurality of different construction machines 2 using the portable terminal 3 that is owned. Moreover, the construction machine management system 1 and the construction machine 2 can perform appropriate work for each worker by transmitting the scheduled work information and the authentication information to the mobile terminals 3 owned by the workers. . Thereby, the construction machine management system 1 can assign the work according to the presence or absence of the license of the worker and the labor status (working time, work content).

  In addition, the construction machine management system 1 may determine whether to drive the construction machine 2 based on the worker's personal information stored in the mobile terminal 3. For example, when the personal information of the worker stored in the portable terminal 3 does not include information holding the operation license of the construction machine 2, the construction machine 2 may not be driven. Further, when the working time of the worker exceeds a predetermined threshold value, the construction machine 2 may not be driven.

  In addition, the construction machine management system 1 detects work contents based on information acquired from each unit, and sends the summarized work contents to the management terminal 8 to automatically create and send a daily report of the work contents. be able to. Thereby, an operator's burden can be reduced. Moreover, since the work content can be specified based on the information detected by the construction machine 2 or the mobile terminal 3, the work content of objective and detailed information can be created.

  In addition, by using the portable terminal 3 that is detachable from the construction machine 2 and includes the camera 48, a work site photograph taken by the camera 48 can be included in the work content. Thereby, even when an image is required for the daily report, a necessary image can be acquired at any time. For example, the mobile terminal 3 can acquire a photograph of a target part of a work at a work site (a faulty part in the case of repair of a fault) and send it as work content so that a person who is not on-site can also determine the faulty part. It becomes possible to arrange necessary parts appropriately. In addition, by capturing a two-dimensional barcode attached to the target component, it is also possible to acquire information on faulty part information and check on the inspection location.

  Moreover, it is preferable that the construction machine management system 1 displays various information on the display unit 40 of the portable terminal 3 during driving and is used as a monitor of the construction machine 2. By using the display unit 40 of the portable terminal 3 as a monitor, the operator can check various information on the display unit 40. Thereby, a construction machine without a monitor can be a construction machine with a monitor, and a construction machine with a monitor can be a construction machine with more monitors (multi-monitor). Moreover, it is preferable that the construction machine management system 1 and the construction machine 2 can input the operation of the construction machine 2 to the operation unit 42 of the portable terminal 3 when driven. That is, it is preferable that various operations of the construction machine 2 can be executed with the touch panel configured by the display unit 40 and the operation unit 42. Thereby, the portable terminal 3 can be used as an operation unit of the construction machine 2, and more operations can be input during work.

  Moreover, the construction machine management system 1 can notify the operator of the next operation to be performed by acquiring the scheduled work information (information about the contents of the scheduled work) in advance. In other words, the work can be navigated. Thereby, the load with respect to an operator can be reduced.

  Moreover, it is preferable that the construction machine management system 1 executes various arithmetic processes in the terminal control unit 54 of the mobile terminal 3 and uses the control function of the terminal control unit 54 as the control unit of the construction machine 2. As described above, by executing various processes in the terminal control unit 54, various processes can be smoothly realized even in a configuration in which the processing capability of the vehicle body control unit 24 is low. Thereby, the vehicle body control part 24 can be made into a simple structure, the structure of the construction machine 2 can be simplified, and the apparatus can be made inexpensive.

  Moreover, since the construction machine management system 1 can detect the use state and the use frequency of each construction machine 2 with the management terminal 8, it can judge the necessity of the maintenance of the construction machine 2, etc. in advance. Thereby, since the correspondence between the work content to be executed and the construction machine 2 to be used can be appropriately determined, work efficiency can be improved and the burden on the operator can be reduced.

  The construction machine management system 1 can notify the operator of the position of the construction machine 2 at the time of reuse by acquiring and storing the position information of the construction machine 2 at the time of stopping with the portable terminal 3. In addition, by managing information collectively, it is possible to notify necessary information even when an operator different from the previous day uses the construction machine 2.

  In addition, by using the portable terminal 3 that the worker owns and using the portable terminal 3 of the worker and the construction machine 2 when used, the processing is executed by connecting the worker's portable terminal 3 and the construction machine 2. Can be set according to the user's preference.

  Further, the mobile terminal 3 may acquire sound and determine the state of the construction machine 2. Specifically, the engine sound or the like of the construction machine 2 may be acquired to determine whether an abnormal sound has occurred.

  In addition, when the mobile terminal 3 can communicate with the base station 4, the construction machine management system 1 preferably transmits work content information to the management terminal 8 during work on the construction machine 2. This makes it possible to quickly determine the assistance that is needed during the work.

  Further, the mobile terminal 3 can obtain the control software and the application program by downloading using a communication line. In addition, the construction machine 2 can also obtain control software and application programs by downloading via the portable terminal 3. Thereby, a required program can be acquired at any time, and the update of a program can be performed easily.

  The construction machine management system 1 collects and accumulates construction data by removing the portable terminal 3 from the construction machine 2 and taking measurements and photographs using the photographing function of the camera 48 and the position detecting function of the GPS unit 50. can do. The construction machine management system 1 can also remove the portable terminal 3 from the construction machine 2 and acquire and accumulate failure diagnosis data of the construction machine 2.

  The construction machine management system 1 can acquire information such as coordinates, inclination, azimuth, temperature, and weather by the detection result of the sensor 46 of the mobile terminal 3 and communication with the network via the base station 4. For example, as the sensor 46 of the mobile terminal 3, the inclination, direction, and position of the construction machine 2 are determined based on the information acquired by the electronic compass, the gyro sensor, and the acceleration sensor, and the positional information acquired by the GPS unit 50 as necessary. By detecting and displaying on the display unit 40, it can be utilized for the work of the operator. In addition, the construction machine management system 1 executes the tilt prevention control and the posture control based on the detected coordinates, inclination, and direction of the construction machine 2, so that the worker can work more smoothly. The tilt prevention control and the posture control may be executed by the terminal control unit 54 or the vehicle body control unit 24. Further, the construction machine management system 1 measures the number of operations by measuring the turning of the construction machine 2 based on the detected coordinates, inclination, and direction information of the construction machine 2, for example, information detected using an electronic compass as a sensor. You may make it count.

  Moreover, when the drive source of the construction machine 2 is an electric motor and the construction machine 2 is configured to be chargeable, it is possible to acquire information on the electricity charges used for charging. In addition, the construction machine management system 1 displays on the display unit 40 of the portable terminal 3 the state of charge acquired from the construction equipment 2, the electricity bill used, and the time zone that can be charged at a low cost acquired via the network 6 or the like. Is preferred.

  The mobile terminal 3 can be a mobile station for RTK-GPS (Real Time Kinematic GPS) surveying using the functions of the GPS unit 50 and the communication unit 44.

  The construction machine management system 1 may enable the construction machine 2 to be operated by the portable terminal 3 even when the portable terminal 3 and the construction machine 2 are not connected. In this case, the construction machine 2 needs to have a wireless communication function such as a short-range communication unit. Thus, by making the construction machine 2 remotely operable with the portable terminal 3, the construction machine 2 can be operated at a position away from the cockpit 28, and the construction machine 2 can be operated at a position where the work target is easy to see.

  The construction machine management system 1 may perform navigation to the destination and the construction site (work place) based on the position information detected by the GPS unit 50 of the mobile terminal 3 and the map information of the scheduled work information.

  The construction machine management system 1 may display an image on the display unit 40 of the portable terminal 3 or output a voice to provide guidance on the contents of the scheduled work. For example, the construction location, precautions (pipe or cable is buried, etc.), final shape, etc. are notified. Thereby, the operator can understand the work to be constructed next more reliably and can smoothly perform the work.

  The construction machine management system 1 can communicate with the outside (another communication terminal) via the mobile terminal 3, thereby receiving information from the outside and notifying a warning by image display or sound. For example, when it is detected that a dump is approaching within a predetermined distance by another communication terminal, a warning can be output. In addition, the state of the construction machine 2 to which the mobile terminal 3 is connected can be output to another communication terminal and used for warning and control in another communication terminal and other construction machine. For example, the payload (maximum load capacity) of the construction machine 2 can be output to the outside, or a work support request can be output.

  The construction machine management system 1 may be a system that lends the construction machine 2 as a rental to the worker of the portable terminal 3. In this case, the usage record can be detected based on various information acquired from the mobile terminal 3 and charged. Further, since authentication information is provided to a specific mobile terminal 3, an operator (user) can be specified.

  In the above embodiment, the communication line between the construction machine 2 and the portable terminal 3 is a wired line. However, communication using a non-contact IC, communication using a wireless LAN, or Bluetooth (registered trademark) is used. You may communicate by communication etc.
