Description

  The present invention relates to a technique capable of acquiring dynamic data of a work machine operating on the site at a remote location.

  Conventionally, for the convenience of users of work machines, a system for acquiring dynamic data of work machines operating at the work site from terminals such as remote maintenance centers and offices using a communication line has been proposed and operated. Has been. A system disclosed in Japanese Patent No. 30112256 (Patent Document 1) is one of them, as shown in FIG. 6, between a management unit 50 serving as a center and each work machine 51 via a wireless communication line. In this system, the remote management unit 50 acquires the dynamic data of the work machine 51 at the site. Further, in this system, as shown in FIG. 7, it is possible to acquire the dynamic data by accessing the work machine 51 from the terminal 52 of the customer who is the owner of the work machine 51 and the portable terminal 53 of the service person at the store. It has become a thing. Therefore, in this system, if the mechanism is configured to transmit the abnormal state of the work machine 51 as warning data to the management unit 50, it is possible to know the theft and unauthorized use of the work machine from a remote location.

On the other hand, theft that causes the work machine to be forcibly stopped by sending an engine stop command from the management unit when the work machine moves outside the area set by applying the data transfer mechanism of the remote management system. A prevention system has also been proposed as Japanese Patent No. 3597772.
Patent No. 30112256 (0028 stage, FIG. 1, FIG. 7) Patent 35977772 (0008 steps)

  However, in the system of Patent Document 1, the controller for data transmission in each work machine is basically a mechanism that interlocks with the engine key switch. Therefore, while the engine of the work machine is stopped, the controller is remotely located. There was a problem that data could not be transmitted. Although a mechanism is considered in which the power is held for about 5 to 10 minutes after the engine key switch is turned off by a timer or the like so that transmission can be performed during the timer start (see Patent Document 1, stage 0028). Since the data cannot be transmitted while the machine is completely stopped, the state cannot be known if the work machine is stolen or illegally used during that time.

  Further, even in the system of Patent Document 2, when the engine of the working machine is stopped and transferred to the outside of the setting area and stolen (for example, transported to a truck or the like), warning data is not transmitted. The management unit cannot recognize theft, and even if it is moved out of the setting area by driving the engine, if the engine is stopped outside the setting area, the work machine cannot receive a stop command from the management unit The anti-theft function may not work.

  The present invention was devised in view of the above problems of the conventional system. When the work machine moves out of the set area regardless of the state of the work machine, the information is immediately sent to the remote management unit. It is intended to provide a work machine side dynamics data management device that has a function capable of informing the user and, in some embodiments, a function of stopping the work machine according to his / her own judgment.

  For this reason, the work machine side dynamics data management device according to the present invention is a work machine side dynamics data management device of a remote management system that obtains the dynamic data of the work machine at a remote location by communication means. A power source to be operated is directly obtained, and a position information acquisition unit is provided to acquire current position information from the unit. Based on the position information, the control unit determines that it is outside an arbitrarily set area. In such a case, a process of either outputting a command for transmitting the warning data to the management unit or outputting a command for preparing for transmission is performed.

  Here, the dynamic data refers to all data related to the state of the work machine, and includes the warning data. The warning data is mainly information that the current position is outside the set area (outside the expected work area), but other abnormal state information (for example, use date / time, day of the week, etc. is outside the set conditions) Time information). The position information acquisition means means means for acquiring the current position information of the working machine itself, for example, the GPS receiver shown in the embodiment. In addition, the instruction to prepare for transmission refers to an instruction that causes the processing instruction to directly act on data transmission. For example, a process that becomes a data transmission start key as in an embodiment described later. Refers to commands to be executed.

  Further, in the present invention, the engine start control mechanism is formed in the work machine, and when the control unit determines that the current position information acquired from the position information acquisition unit is outside the arbitrarily set region, the engine start is It is also possible to output a command for limiting the engine to the engine start control mechanism.

  In the present invention, even when the work machine is completely stopped, if the work machine is forcibly moved out of the setting area, the information is immediately transmitted to the management unit. Of course, even when the work machine is operated by the theft and moved out of the setting area, the information is transmitted to the management unit. In any case, when the work machine moves out of the setting area, the abnormal state can be quickly detected at a remote place. Therefore, subsequent actions can be taken immediately.

  Further, if the construction is such that not only the transmission of warning data but also the engine start is stopped on the work machine side, the work machine will not operate thereafter. In addition, in this case, since the stop control is performed on the work machine side, the stop control is executed even when the management unit moves to an area where communication is impossible, which is extremely useful as a theft prevention mechanism.

  The work machine side dynamic data management device according to the present invention is premised on the provision of a function of transmitting dynamic data to a remote management unit. Depending on a further aspect, the dynamic data is transmitted from the management unit to the user by a predetermined means. Can also be provided. In such a mode, even when the work machine is not operating, when the user desires the dynamic data, the user can obtain the data through the management unit. You can also get about.

  Specific embodiments of the present invention will be described with reference to the drawings.

  1 is a block diagram showing the entire remote management system, where 1 is a management unit, 2 is a work machine, 3 is a customer terminal, 4 is a dealer terminal, 5 is a mobile phone network, 6 is an Internet network, and 7 is Intranet network, 8 is a GPS satellite, 9 is a relay antenna, 30 is a customer's mobile phone, and 40 is a service man's mobile phone.

  The management unit 1 functions as a center for operating this system. In this embodiment, the management unit 1 is operated by the manufacturer of the work machine. For this reason, as will be described later, the management unit 1 side and the store terminal 4 (including the service person mobile phone 40) are connected via the affiliated intranet network 7.

  As shown in FIG. 2, the management unit 1 is formed with a system control device 100 for performing control on the management unit side of the remote management system. The control device 100 includes a communication unit 101, a data connection processing unit 102, A database 103, a mail delivery unit 104, and a network information processing unit 105 are provided (note that these configurations serve as means for functions as described below with a single or a plurality of servers). The communication unit 101 includes a communication device that can use the mobile phone network 5 and performs data communication with the work machine 2 via the mobile phone network 5. The data connection processing unit 102 controls data exchange with the work machine 2 side and the customer terminal 3 (including the mobile phone 30), which is the user, and the store terminal 4 (including the serviceman mobile phone 40), and a server that performs the processing. Is provided. The database 103 includes a vehicle database 130 and a customer information database 131. The vehicle database 130 stores data transmitted from the work machine 2 side, and the customer information database 131 is transmitted from the customer master via the in-house intranet network 7. Data about customers that are updated sequentially is stored. In the Web site to be described later, the information of each database 130 and 131 is provided to the user in a manner in which the information is attached. The customer information mail distribution unit 104 is a mail server for transmitting an email indicating that there is warning data to the customer mobile phone 30 and the service person mobile phone 40 when warning data is transmitted from the work machine 2 side described later. Is provided. Therefore, the addresses of the customer mobile phone 30 and the serviceman mobile phone 40 to be transmitted are stored in the memory of the mail delivery unit 104. The network line information processing unit 105 includes a Web server that manages a Web site, and exchanges data with the customer terminal 3 and the store terminal 4 through the Web site. In this embodiment, since the customer terminal 3 uses the Internet line network 6 and the store terminal 4 uses the intranet line network 7, the Web server is provided with a gate for each line to exchange data. The route is divided for each network 6,7. In addition, in order to make a request for obtaining predetermined data from the Web site, login with an ID and a password is a condition. For this reason, an ID and a password are given to a customer and a serviceman who are permitted to access.

  As shown in FIG. 3, the work machine 2 is provided with a dynamic management controller 20 that is a dynamic data management device that controls data exchange between the inside and outside of the machine. In the electrical system of this embodiment, a main power supply circuit directly connected to a battery (not shown) of the work machine 2 is formed, and the dynamic management controller 20 and the engine start circuit are connected to the main power supply circuit in parallel. Yes. Therefore, even if the engine key switch is turned off, the dynamic management controller 20 is in an operating state unless the main power switch (disconnect switch) is turned off. The above electric system may be in any other form as long as the dynamic management controller 20 is directly connected to the battery and the on / off of the controller 20 is not linked to the on / off of the engine key switch.

  The work machine 2 is also provided with a vehicle body controller 21 that controls various devices of the vehicle. Unlike the movement management controller 20, the vehicle body controller 21 is connected to an engine key switch circuit and interlocks with on / off of the key switch. The vehicle body controller 21 is connected to various devices 23 (engines, pumps, sensors, etc.), takes out predetermined operation data therefrom, and stores them in an internal storage unit. The behavior management controller 20 is connected to the vehicle body controller 21 via the in-vehicle network 22, and the operation data captured by the vehicle body controller 21 is captured by the behavior management controller 20 via the network 22 (specifically, Are taken in from the wired communication unit 202 described later and stored in the operation data storage unit 210). Depending on the model, there is a mode in which the vehicle body controller 21 is not installed. In this mode, the various devices 23 are connected to the dynamic management controller 20 (the input / output signal processing unit 207 in FIG. 3) to directly operate data. It may be imported.

  As shown in FIG. 5 (a), the vehicle body controller 21 is connected to the engine controller 24 via the in-vehicle network 22 and outputs a command signal for stopping the fuel injection of the engine 25. It is a command signal from the behavior management controller 20 described later that causes the vehicle body controller 21 to output the command signal. The command signal is also output by the processing of the arithmetic processing unit 200 described later. This command system is the engine start control mechanism in this embodiment. Of course, the engine start control mechanism may take other forms, for example, as shown in FIG. 4B, a relay 27 is added to the engine start circuit 26, and the relay 27 is driven by the command from the dynamic management controller 20. Thus, a mechanism for stopping the starter motor 28 may be used.

  As shown in FIG. 3, the activity management controller 20 includes an arithmetic processing unit 200 as a main control unit, a storage unit 201, a wired communication unit 202, a wireless communication unit 203, a position measurement unit 204, a date management unit, 205, a power supply control unit 206, and an input / output signal processing unit 207. The arithmetic processing unit 200 outputs a command to each of the constituent units 201 to 206 with respect to data exchange in the controller 20 or the like. The arithmetic processing unit 200 is also the processing entity for the input / output of warning data and the control commands based on it, which are features of the present invention, which will be described later. The storage unit 201 stores operation data of the work machine 2, warning data, and setting data in which conditions serving as a command reference for the arithmetic processing unit 200 are described. In this embodiment, a memory is assumed as the storage unit 201, but other storage means may be used. In the storage unit 201, the storage area is divided into three parts, that is, an operation data storage unit 210, a spontaneous transmission data storage unit 211, and a setting data storage unit 212 in accordance with data to be stored. The wired communication unit 202 performs data communication with another controller in the work machine (the vehicle body controller 21 in the present embodiment) via the in-vehicle wired network 22. The wireless communication unit 203 includes a wireless communication device that can use the mobile phone line network 5 and a memory, and performs data communication with the communication unit 101 of the management unit 1 via the mobile phone line network 5. In the memory, the telephone number (contact data) of the management unit 1 communication unit 101 is stored, and an area for storing a call e-mail from the communication unit 101 is set. The position measuring unit 204 includes a GPS receiver, receives a radio wave from the GPS satellite 8, and measures the current position. This position information is a reference for warning data transmission and engine start control start in this embodiment. The GPS receiver is provided with a sensor (not shown) for detecting the disconnection of the antenna connection line. The date management unit 205 includes a clock means and a rechargeable battery, maintains date and time even when the main power is turned off, manages the date and time data, and when the date / day of the week / time set in advance by the arithmetic processing unit 200 is reached, the arithmetic processing unit Output to 200. As will be described later, these date and time data serve as a reference for engine start control in this embodiment. The power supply control unit 206 controls on / off of the internal power supply.

  The storage of each data in the storage unit 201 is processed according to a command of the arithmetic processing unit 200, and the operation data is stored in the operation data storage unit 210 from the vehicle body controller 21 via the in-vehicle network 22. In addition, if there is abnormal data corresponding to the occurrence of a warning, which will be described later, among the operation data, it is stored in the spontaneous transmission data storage unit 211 as warning data. When warning data is stored in the spontaneous transmission data storage unit 211, the arithmetic processing unit 200 outputs a command for transmitting the warning data to the management unit 1 side to the wireless communication unit 203. In other words, storing the warning data in the spontaneous transmission data storage unit 211 serves as a warning data transmission start key. These control instructions of the arithmetic processing unit 200 are based on the setting data stored in the setting data storage unit 212 of the storage unit 201, but the setting data to be updated are transmitted from the management unit 1 side, The data is stored in the data storage unit 212.

  Next, data processing at the time of occurrence of warning in the behavior management controller 20 will be described. In this embodiment, as the mode of occurrence of warning, (1) when the current position of the work machine 2 is outside the set area, (2) when the operation of the work machine 2 is other than the set date, (3) When the operation of the work machine 2 is other than the set day, (4) When the operation of the work machine 2 is other than the set time, (5) When the antenna connection line of the GPS receiver is disconnected Assumed. Therefore, the setting data storage unit 212 stores condition data indicating the specific ranges of the five modes that generate warnings as setting data, and the arithmetic processing unit 200 includes position information from the GPS receiver, Whether the date / time information / day of week information / time information by the clock means and the antenna connection line disconnection information from the sensor are input, and the information is checked against the conditions of the setting data to determine whether a warning should be generated or not. Is judged. Hereinafter, the flow of this determination process will be described in detail with reference to FIG. Note that the mode (including the condition data) that causes the warning is not limited to the present embodiment, and other modes may be assumed.

  First, as long as the main power source is switched on, the arithmetic processing unit 200 determines whether or not the current position of the work machine 2 is outside the set area based on the position information from the GPS receiver (S1). If it is determined from the position information that the current position is out of the set area, warning data that is out of the area is stored in the spontaneous transmission data storage unit 211 of the storage unit 201 (S2). The arithmetic processing unit 200 checks whether or not the warning data is stored in the spontaneous transmission data storage unit 211 separately from the flowchart of FIG. 4. When the warning data is stored, the arithmetic processing unit 200 displays the warning data as described above. It is taken out and transmitted from the wireless communication unit 203 to the management unit 1 side (this spontaneous transmission processing is the same in the following flow). This process is always performed as long as the main power supply is switched on. Therefore, according to the above flow, even when the work machine 2 is stopped, the warning data is automatically transmitted to the management unit 1 side when the work machine 2 is moved out of the set area. . Therefore, the management unit 1 can immediately detect the abnormal state, and the management unit 1 also reflects the warning data on the website and sends an e-mail to the registered customer mobile phone 30 and serviceman mobile phone 40. Therefore, the user can immediately know the abnormal state.

  Returning to FIG. 4, next, the arithmetic processing unit 200 determines whether or not the engine key switch is turned on (S3). When the switch is turned on, whether or not the position information is out of the setting area again. Is determined (S4). If it is determined that it is out of the area, the start restriction flag is turned on (S5), and the warning data is stored in the spontaneous transmission data storage unit 211 (S6). If it is within the area, the process proceeds to the next determination flow. Next, based on the date information from the clock means, it is determined whether it is within the set date (S7). If it is determined that it is outside the set date, the start restriction flag is turned on (S8), and warning data is stored in the spontaneous transmission data storage unit 211 (S9). If it is within the set date, the process proceeds to the next determination flow. Next, it is determined whether it is a set day of the week based on day information from the clock means (S10). If it is determined that it is outside the set day of the week, the start restriction flag is turned on (S11), and warning data is stored in the spontaneous transmission data storage unit 211 (S12). If it is within the set day of the week, the process proceeds to the next determination flow. Next, it is determined based on the time information from the clock means whether or not it is within the set time zone (S13). If it is determined that it is outside the set time period, the start restriction flag is turned on (S14), and the warning data is stored in the spontaneous transmission data storage unit 211 (S15). If it is within the set time zone, the process proceeds to the next determination flow. Next, it is determined whether or not the antenna connection line is disconnected based on the antenna connection line information from the sensor (S16). If it is determined that there is a break, the start restriction flag is turned on (S17), and warning data is stored in the spontaneous transmission data storage unit 211 (S18). If it is within the set time zone, the process proceeds to the next determination flow. Finally, it is determined whether or not the start restriction flag is turned on (S19). If the start restriction flag is turned on, an engine fuel injection stop command signal is output to the vehicle body controller 21 (S20). After the command signal is output, the flag is reset (S21). Therefore, according to the above processing flow, whether the work machine 2 has been moved outside the set area, is operating outside the set date, day of the week, or time zone, or the antenna connection line of the GPS receiver is disconnected. If any of the above is true, warning data is sent to the management unit 1 to immediately notify the user of the abnormality in the same manner as described above, while stopping the engine start and immediately stopping the unauthorized use state. Can be made. As described above, the processing flow of S3 to S21 is all executed when the engine key switch is turned on, but as long as the main power switch is turned on as in the processing of S1 to S2. The system may be constantly monitored.

  Further, the arithmetic processing unit 200 performs transmission processing of operation data other than warning data as follows. First, it is always checked whether a call e-mail from the management unit 1 communication unit has been received and stored in the memory. If a call e-mail is sent, it is received by the wireless communication unit 203 and immediately received. Save it in its own memory. When the checked arithmetic processing unit 200 confirms the storage, the wireless communication unit 203 retrieves the telephone number of the management unit 1 communication unit from its own memory and makes a call to the management unit 1 side. When the wireless communication unit 203 communicates with the management unit 1 communication unit, if there is a setting command from the management unit 1 communication unit, it is transmitted, and at the same time, a transmission request for the desired work machine 2 is transmitted. The arithmetic processing unit 200 first confirms whether or not a setting command has been received, and if received, saves it in the setting data storage unit 212 of the storage unit 201 and updates it. Return to the side. As described above, the setting data is a control command of the arithmetic processing unit 200, and after the update, control is performed based on the updated setting. Next, the arithmetic processing unit 200 confirms the operation data request, extracts the operation data of the desired work machine 2 from the operation data storage unit 210, and transmits the operation data from the wireless communication unit 203 to the management unit 1 communication unit (note that On the management unit 1 side that has received the operation data, the data is reflected on the Web site and information is provided to the user). Next, the arithmetic processing unit 200 confirms the presence or absence of warning data in the spontaneous transmission data storage unit 211 of the storage unit 201, and if there is warning data, retrieves the data from the wireless communication unit 203 to the management unit 1 communication unit As described above, the data is transmitted to. The arithmetic processing unit 200 forcibly disconnects the line when a predetermined time has elapsed after each data transmission. The above processing flow is all performed as long as the main power switch is turned on, and thus is performed even when the engine key switch of the work machine 2 is not operating in the off state.

  As described above, according to the system of the present embodiment, even if the work machine 2 is in a completely stopped state, if the state is such that the work machine 2 is forcibly moved out of the setting area, the warning data is The message is immediately sent to the management unit 1, and an e-mail is sent from the management unit 1 to the user. Therefore, the user can quickly detect the abnormal state at a remote place, and the subsequent response can be taken immediately.

  Moreover, not only the transmission of warning data but also a situation that corresponds to the occurrence of a warning, the work machine 2 is controlled to stop the engine start, so the work machine 2 cannot communicate from the management unit 1. Even if the vehicle moves to the area, stop control is executed, which is extremely useful as an anti-theft mechanism.

  Needless to say, the present invention is not limited to the above embodiments.
