Description

[Technical Field]

[0001] The present invention relates to a construction machine operation optimization system and a construction machine operation optimization method that accurately manage the operation of construction machines. [Background technology]

[0002] Conventionally, as a system for preventing theft of vehicles, for example, Patent Document 1 discloses a vehicle management system that photographs the face of the user of a specified vehicle, registers the facial data for each corresponding vehicle, and authenticates the person by comparing the face with the face of a person who is near the vehicle and intends to use the vehicle, and determines whether or not to allow the use of the vehicle.

[0003] Meanwhile, in recent years, IT-based cloud computing has become more widespread, and by making effective use of this technology, there is no longer a need to have large-capacity internal servers within a company, reducing development investment and making it more rational and economical.Amid this promotion of IT, the construction industry is also in the process of building a dedicated cloud computing-based server Construction Career Up System (CCUS), which registers the employment record and qualifications of each and every skilled worker across Japan, which is equivalent to big data, and aims to lead to fair evaluations of skills, improved construction quality, and more efficient on-site work (see Non-Patent Document 1).

[0006] The vehicle management system disclosed in Patent Document 1 is susceptible to misidentification because it only uses a facial recognition method that compares facial data. Furthermore, if the amount of registration information required for security authentication in these systems becomes enormous, the system may become unusable or the authentication response speed may become slow, which may result in a problem that the original purpose of fast and appropriate vehicle management from a security perspective is not achieved.

[0007] Therefore, the present invention makes effective use of a dedicated server specialized for the construction machinery industry to optimize construction machinery operation, thereby eliminating accidents caused by unqualified operators and preventing theft. [Means for solving the problem]

The second invention is characterized in that, in the first invention, if the comparison result from the internal server is positive, the card reader sends a control signal to the construction machinery engine control unit, which controls the startup of the construction machinery, to transition it to a startable state. A third invention provides a method for making a card reader start reading a card; determining the authenticity of the card; If it is determined that the card is not the card, an error occurs and the process returns to reading again, and if it is determined that the card is the card, the card is read; A step of sending the technician ID and the construction machine ID to an internal server; The internal server, which is interposed between the card reader and the external server, performs and manages the link between the card ID and the construction machine ID, and temporarily stores the link; the internal server accesses the external server and transmits the temporarily stored data of the technician ID and the construction machine ID; retrieving the person's credentials from an external server; If it is determined that the qualification information cannot be acquired, the external server is accessed again to send the temporarily stored data of the technician ID and construction machine ID.

[0009] According to the present invention, by effectively utilizing a dedicated server specialized for the construction machinery industry, it is possible to optimize the operation of construction machinery, thereby eliminating accidents caused by unqualified operators and preventing theft. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a block diagram of a skilled worker card issuing system according to one embodiment of the present invention. [Figure 2] FIG. 2 is a block diagram of a construction machine startup according to an embodiment of the present invention. [Figure 3] 4 is a flowchart of a construction machine startup operation according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0011] This invention explains a method for issuing a skilled worker card that can access a dedicated server of the Construction Career Up System (hereinafter referred to as CCUS), which manages the qualification information of skilled workers, in order to utilize the CCUS. As shown in Figure 1, a construction industry person S applies online to an external server 2, the dedicated server of CCUS (hereinafter simply referred to as the external server), to register personal information such as name required for the skilled worker card and license qualification information for construction machinery (sometimes simply referred to as construction machinery for short). If approved, the person can obtain a skilled worker card A on which this information is stored.

[0012] Once a worker has obtained the technician card A, he or she is ready to operate the construction machine 1 within the scope of the personal information and construction machine license qualifications registered on the external server 2, and can use the construction machine operation optimization system. Such a construction machinery operation optimization system is composed of a card reader that reads the data necessary to start construction machinery from a card on which the data is recorded, an external server that stores the data, and an internal server that is located between the card reader and the external server.The internal server performs a process of comparing the read data sent from the card reader with the sent data sent from the external server and sending the results of the comparison to the card reader. Furthermore, if the collation result from the internal server is positive, the card reader causes the construction machine engine control unit, which controls the start-up of the construction machine, to transition to a start-enabled state. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3 as needed.

[0013] Construction machinery 1 is a general term for machinery used in civil engineering and building construction work, such as hydraulic excavators, demolition-spec hydraulic excavators, crawler cranes, hydraulic cranes, tower cranes, aerial work platforms, truck-mounted cranes, and concrete vibrators. These are also called construction machinery, heavy machinery, or earthmoving machinery for short, and are used to mechanize work that is difficult to carry out manually.

[0014] In such a construction machine 1, a construction machine data registered dedicated reader (hereinafter simply referred to as card reader) 11 that reads out the information registered on the skilled worker card A is installed inside the driver's cab and is electrically connected to the engine start control unit 12. Electrical signals are transmitted using serial communication or non-voltage contacts. When the card reader 11 is installed, a link is established between the construction machine 1 and the construction machine ID, which is a unique identification number. Although not shown, the card reader 11 also has a storage and recording means for storing various types of information, a communication means for sending and receiving communications with the outside, a display means such as an error lamp, and a power supply means for supplying power. This card reader 11 can also be retrofitted to construction machines 1 that are already in use, which leads to enhanced security.

[0015] The card reader 11 uses known contact or contactless technology for reading data from cards, etc., and the reading method is not particularly limited. For example, reading may be performed using the same method as a general card reader, such as near field communication (NFC).

[0016] Such card reader 11 starts reading the technician card A (step S1), and determines whether it is the technician card A or not (step S2), and if it is determined that it is not the technician card A, it returns to reading again as an error, and if it is determined that it is the technician card A, it is read (step S3). Then, the technician ID and construction machine ID are sent to the internal server 3 (step S4).

[0017] An example of an error here is when a different card, other than a technician card, is inserted into the dedicated reader 11 for registered construction machinery data. Although this error processing is not shown in the diagram, the error lamp on the card reader 11 lights up red to alert the worker, and error data is sent to the internal server 3, and an alert is displayed on the operation screen for the work manager. Note that if there is no error and the card reader 11 is OK, the lamp lights up blue.

[0018] The card reader 11 also has a communication means for sending and receiving data to and from the internal server 3 in accordance with a communication protocol. That is, when the card reader 11 accepts the reading of the technician card A and obtains the technician's personal information stored therein, it transmits the ID data and other information in which the personal information is stored to the internal server 3. The communication means uses LTE, and the data transmitted to the internal server 3 includes the transmission date, hour, minute, second, construction machine ID, technician ID, and the like, using a communication SIM.

[0019] The internal server 3 is interposed between the card reader 11 and the external server 2, and, for example, links and manages the technician ID and construction machinery ID on the technician card A according to the API procedure, and temporarily stores the data (step S5).The internal server 3 then accesses the external server 2 according to the API procedure via the Internet, and sends the temporarily stored technician ID and construction machinery ID data (step S6), and references and obtains the person's qualification information from the external server 3 (steps S7, YES in step S8), and if it determines that the qualification information cannot be obtained (NO in step S8), it returns to step S6, accesses the external server 2 again, and resends the temporarily stored technician ID and construction machinery ID data (step S7).

[0020] Although not shown in the figure, the internal server 3 is connected to a computer for setting up equipment and a computer for managing usage history, which are used for server processing such as linking the card reader 11 with the construction machine ID, managing the communication status between the internal server 3 and the external server 2, and updating data. The computer also has a storage and recording means for storing various information, a communication means for sending and receiving communication, a screen display means, and a power supply means for supplying power.

[0021] Next, the internal server 3 compares and collates the acquired and temporarily stored data of the technician ID and construction machinery ID (step S9). If the collation result from the internal server 3 is positive, the card reader 11 sends a control signal to the construction machinery engine control unit 12, which controls the startup of the construction machinery 1, to transition to a start-enabled state. In other words, if the card reader 11 determines whether or not the construction machinery license is held and the result is "yes" (step S10), it sends a control signal for start-enabled processing to the construction machinery engine control unit 12, and engine start-enabled processing is performed to put the engine into a state where it can be started (step S11). If the determination of whether or not the construction machinery license is held and the result is "no" (step S10), error processing is performed (step S12).

[0022] In this way, by effectively utilizing a dedicated server (cloud computing) specialized for the construction machinery industry, and by verifying the technician card A in the card reader 11 of the construction machinery operation optimization system, and by checking the internal server 3 to verify whether or not the technician is qualified to operate a construction machinery license, it is possible to achieve optimization of construction machinery operation, which will eliminate accidents caused by unqualified operators operating construction machinery and prevent theft.

[0023] As an additional embodiment, the card reader 11 and a breathalyzer can be linked via short-range communication (e.g., Bluetooth) to have a means for checking the breath of the technician with the breathalyzer (not shown) and starting the engine only if the breath is "OK." This further improves the optimization of construction machinery operation, making it possible to prevent accidents caused by drunk driving. [Explanation of symbols]
