Detailed Description
(embodiment 1)
The following describes embodiment 1 in which the present invention is applied to the semi-new vehicle determination of a hydraulic excavator, with reference to fig. 1 to 9.
Fig. 1 is a configuration diagram of a system of the present invention. In the present system, the operation information and the like detected by the hydraulic excavator 10 can be transmitted to the construction machine manufacturer (hereinafter, simply referred to as manufacturer) 40 via the communication satellite 80. The result of the check of the hydraulic excavator 10 visually obtained by the service person can be transmitted to the manufacturer 40 via the mobile phone 20 and the online service company 30. Also, the present position of the hydraulic shovel can be detected by the GPS satellite 100. The specific configuration is described below.
Each hydraulic excavator 10 includes a main control unit 11, a communication control unit 12, and a GPS control unit 16 shown in fig. 2. The main control unit 11 is configured with a CPU, a ROM, a RAM, and other interfaces, and executes programs such as a drive control process of the hydraulic excavator and a management process of various data. The main control unit 11 is connected to a switch SW for detecting the state of an engine key as an input and pressure sensors 13, 14, and 15 for detecting an excavation load, a rotation load, and a travel load, respectively. The main control unit 11 obtains operation information of the hydraulic excavator 10 based on input information from various sensors and switches. The operation information is, for example, an engine operation time, an excavation time, a rotation time, a travel time, and the like of the construction machine.
The GPS control unit 16 receives radio waves from a plurality of GPS satellites 100 and calculates positional information of the hydraulic shovel 10. The calculated position information is input to the main control unit 11. The positional information here is information such as longitude and latitude.
The communication control unit 12 has a CPU, a ROM, a RAM, other interfaces, and the like, and executes programs such as various data management processes. The communication control unit 12 transmits the operation information and the position information of the excavator 10 at predetermined time points each day. At this time, an ID number as an identifier for identifying the hydraulic excavator is added to the information. The transmitted information is sent to a predetermined management server via the communication satellite 80. In the present embodiment, the mail server 90 is used as a management server. The information sent to the mail server 90 is then sent to the manufacturer 40 via the communication network 60.
At the manufacturer 40 as a base station, a center server 41, a history database 42, and an operation database 43 are provided. The operation information from the mail server 90 is stored in the operation database 43 via the center server 41. On the other hand, the history database 42 mainly stores information on past repairs, component replacements, and the like of the hydraulic excavator 10. The operation database 43 and the history database 42 store various data corresponding to the ID of the hydraulic excavator.
Fig. 3 shows a control block diagram of the mobile phone (portable information transceiver) 20. The CPU21 is connected to the transmission unit 22, the reception unit 23, the operation unit 24, the display unit 25, and the memory 26. The transmitting unit 22 and the receiving unit 23 are information transmitting and receiving units in the case of using a telephone and an online service mode described later. A plurality of operation keys 24a such as numeric keys are provided in the operation unit 24, and telephone numbers or various kinds of information are input using these keys 24 a. Commands such as start of data transmission and reception and various modes are also input from the operation unit 24. A display 25a, for example, is provided in the display unit 25. Various information can be displayed on the display 25 a.
The mobile phone 20 of the present embodiment can select an online service mode in addition to a general phone mode. This mode is a mode in which an online service for a mobile phone, which is performed by a telecommunications carrier or the like, is used, and internet connection, transmission and reception of mail, and the like are possible via the online service company 30 (fig. 1) and the communication network 60. In the present embodiment, the center server 41 of the manufacturer 40 is accessed to transmit data or, conversely, to receive information transmitted from the manufacturer 40.
In addition, in this mobile phone 20, it is necessary to carry 1 person by the serviceman 1 of the manufacturer 40.
A specific example of the semi-new vehicle verification processing of the system configured as described above will be described below.
(1) Acquisition and storage of operational information
Fig. 4 shows processing of the main control unit 11 of each hydraulic excavator 10. First, as the engine is started, the time is stored in the memory 11A as the engine start time (step S1). Thereafter, if it is determined from the state of the switch SW that the engine is stopped in step S2, the stored start timing is subtracted from the timing (engine stop timing) to calculate the operating time of the hydraulic excavator (step S3). Then, the calculated operation time is added to the operation time of the day that is stored now, and is stored in the memory 11A (step S4). In addition, if the operation time of the day is not stored, the calculated operation time is directly stored. Thus, the total operating time of 1 day is finally stored in the memory 11A.
In fig. 4, the measurement of the running time is illustrated. In addition, the control time, the travel time, the rotation time, and the like may be measured separately. These times can be obtained by performing timing control based on the outputs of the pressure sensors 13 to 15, and the obtained information is stored in the memory 11A.
Fig. 5 shows a process of the communication control unit 12 of the hydraulic excavator 10. When it is determined that the predetermined transmission time has come (step S11), the operation information is read from the memory 11A (step S12), and the read operation information is transmitted (step S13). At this time, the position information of the hydraulic excavator 10 calculated by the GPS control unit 12 and the ID number for specifying the hydraulic excavator 10 are also transmitted at the same time. The transmission is carried out late at night, and the information of the previous day is transmitted every day.
The transmitted information from each hydraulic excavator 10 is sent to the mail server 90 via the communication satellite 80 as described above, and is transferred to the center server 41 of the manufacturer 40. In the center server 41, first, the data storage area of the operation database 43 is searched using the transferred ID number as a key, and the operation information is stored in the area. In this way, the operation information of hydraulic excavator 10 is accumulated for each hydraulic excavator and stored in operation database 43. In addition, the location information is also stored in addition to the operation information.
(2) Transmission of approval information of service person
The transmission of the approval information of the service person is performed according to the steps of fig. 6.
Step 1: acquisition of a certification project
When the service person checks the hydraulic excavator 10, the service person accesses the center server 41 (web address) of the manufacturer 40 in the online service mode of the mobile phone 20. Then, a password is input as necessary, and a predetermined approval item acquisition screen is called up and displayed on the display 25 a. If a predetermined operation is performed on this screen, an approval table (check table) for the hydraulic excavator 10 can be downloaded to the memory 26 of the mobile phone 20. In the received approval table, a plurality of approval items are associated with each approval site of the hydraulic excavator, and a field for filling out an approval result is provided for each item.
The verification items are mainly the contents that cannot be detected by the sensors, such as the damage, deformation, and abrasion of each part shown in fig. 7A to 7D, that is, the contents that the service person visually judges (except for the engine operating time).
Step 2: input of approval results
The service person performs the approval based on the criteria shown in fig. 7A to 7D while displaying the received approval table on the display 25a and confirming the approval item. The reference is explicitly described in the verification table. Then, the result of the verification (the score reduction) for each item is sequentially input by the operation of the key 24a provided in the operation unit 24. The entered information is displayed in the corresponding approval result filling field on the display 25 a.
And step 3: transmission of approval information
When the approval and the input of the approval result are completed for all the items, a transmission command is input from the operation unit 24, and the approval result for each item is transmitted as approval information. At this time, the ID number for specifying the approved hydraulic excavator 10 is transmitted together.
Further, the following may be used: after obtaining the approval table from the center server 41, the approval job and the input job are performed in a temporary off-line state, and the center server 41 is accessed again to transmit approval information. Alternatively, the center server 41 may be connected during a period from the acquisition of the approval table until the transmission of the approval information. Further, the transmission processing of the approval information may be performed by mail.
(3) Calculation of the amount of the accredited money
When the central server 41 of the manufacturer 40 calculates the semi-new vehicle approval amount, the processing shown in fig. 8 is performed. This processing is performed using dedicated software installed in the center server 41. The processing is automatically performed when the approval information is received from the service person.
First, it is determined whether or not approval information from a service person is received (step S21), and when it is determined that the approval information is received, the received information (approval information and ID number) is read (step S22).
Then, the history database 42 is searched for the received ID number, and history information of the hydraulic excavator 10 is read (step S23). The history information is information such as past repair, part replacement, grease replacement, periodic maintenance, accident, update, and the like, and further includes information indicating whether an optional accessory such as an accessory (attachment) has been purchased. The number of the subtraction or the addition is decided based on the information. As shown in fig. 9A, the points are added when optional accessories are present.
The operation information database 43 is similarly searched, and the operation information of the hydraulic excavator 10 is read (step S24). The operation information is the above-described operation time, excavation time, travel time, rotation time, and the like. For example, with respect to the running time, as shown in fig. 7A, the subtraction score is decided corresponding to the time. The reduction score is also determined according to the year of production of the hydraulic excavator 10 (fig. 9B).
From this previous processing, the score reduction (score addition) of all items required for approval is found. In step S25, these points are added, and in step S26, the points obtained by the addition are substituted into a predetermined arithmetic expression and converted into an amount of money (amount of money corresponding to the addition result). On the other hand, the reference price of the hydraulic shovel 10 is read from a predetermined database (step S27), and the sum obtained by adding the sum equivalent to the above-described addition result to the reference price is calculated as the approval sum (step S28). The calculated approval amount is displayed on the monitor of the center server 41 together with the scores of the items that become the basis of the approval (step S29). The display content can be printed out as desired.
As described above, in the present embodiment, the amount of money to be checked for a semi-new vehicle is calculated as follows.
The result of the check (visual check) of the hydraulic excavator 10 by the service person is transmitted from the mobile phone 20 to the server 41 of the manufacturer 40. The server 41 automatically calculates the amount of money to be approved for the semi-new work of the hydraulic excavator 10 based on the received information and the history information and the operation information of the hydraulic excavator 10 read from the databases 42 and 43. Thus, the efficiency of the approval work can be greatly improved and the burden on the service man can be reduced as compared with the calculation of the approval amount by the conventional manual work.
The approval-amount calculation process shown in fig. 8 is a process showing an example, and the approval amount may be obtained by a process different from this process. In addition, although a mobile phone is generally distinguished from a PHS phone, the mobile phone referred to in this specification is a concept including a PHS phone. That is, the above-described transmission and reception may be performed by using a PHS-oriented service. Instead of the portable telephone, a portable personal computer may be used.
(embodiment 2)
Next, embodiment 2 in the case where the present invention is applied to a transmission/reception system of a hydraulic excavator will be described with reference to fig. 10 to 12. The same reference numerals are used for the same portions as those in the system block diagram of fig. 1, and the differences will be mainly described.
Fig. 10 is a schematic diagram showing a system configuration of the present embodiment. In the present embodiment, the mobile phone 20 can be used to transmit the inspection result of the excavator 10 to a construction machine manufacturer (hereinafter, simply referred to as manufacturer) 40 or a construction machine leasing company 50 via an online technical service company 30. At the manufacturer 40 and the rental company 50, center servers 41, 51 and databases 42, 52 storing overhaul information and the like are provided, respectively. The server 41 of the manufacturer 40 is hereinafter referred to as a central server.
Fig. 11 shows a procedure of the inspection information transmission processing by the above-described system.
Step 1: acquisition of service items
When the service person of the manufacturer 40 or the rental company 50 performs the inspection of the hydraulic excavator 10, the center server 41 (web site) of the manufacturer 40 is accessed by using the online service mode of the mobile phone 20. Then, a password is input as necessary, and a predetermined inspection item acquisition screen is called up and displayed on the display 25 a. When a predetermined operation is performed on this screen, the mobile phone 20 can receive a maintenance table (check table) for the hydraulic excavator 10 and download the table to the memory 26. In the maintenance table, a plurality of maintenance items are associated with each maintenance site of the hydraulic excavator, and a field for filling out a maintenance result is provided for each item.
The inspection items are mainly the contents that cannot be detected by the sensors, such as damage to each part and a defect in a component (contents that a service person visually judges).
Step 2: input of inspection results
The service person performs the maintenance work while displaying the received maintenance table on the display 25a and confirming the maintenance items. Then, the inspection results for each item are sequentially input. The input is performed by operating keys 24a provided in the operation unit 24. The entered information is displayed in the corresponding repair result filling column on the display 25 a.
And step 3: transmission of service information
When the inspection and the input of the inspection results are completed for all the items, a transmission command is input from the operation unit 24, and the inspection results of the items are transmitted as the inspection information. At this time, the ID number for specifying the hydraulic excavator 10 after the inspection is transmitted together.
Further, the following may be used: after obtaining the maintenance table from the center server 41, the maintenance work and the input work are performed in a temporary off-line state, and the center server 41 is accessed again to transmit the maintenance information. Alternatively, the center server 41 may be connected to the maintenance table until the maintenance information is transmitted and received. In addition, the transmission processing of the inspection information may be performed by mail.
The process shown in fig. 12 is performed in the center server 41 of the manufacturer 40. It is determined whether or not service information from a service person is received (step S110), and if it is determined that the service information is received, the received information (service information and ID number) is read (step S210). The entered information is then stored in the database 42 corresponding to the ID number (step S130)
The following constitution is also possible: the experience database 42 of the manufacturer 40 is used as a shared database, and the rental company 50 extracts the repair information on the owned equipment of the company from the experience database 42 of the manufacturer 40 as needed and stores the repair information in the database 52 of the company. In this case, a rental ID number that identifies the state of the hydraulic excavator held by the rental company 50 may be stored in the database 42 in association with the ID number that identifies the hydraulic excavator. The center server 41 may be constituted such that: when the excavator ID number is input together with the rental ID number from the rental company 50, transmission of various data to the server 51 of the rental company 50 is permitted in accordance with the data extraction request of the rental company 50.
Alternatively, the following may be used: when the service person of the rental company 50 transmits the inspection information by using the mobile phone in which the same software as that of the mobile phone 20 is loaded, the inspection information is transmitted to the manufacturer 40 and the inspection information is also transmitted to the rental company 50 to which the service person belongs. In this case, when data is transmitted, a rental ID number for identifying the state of the hydraulic excavator held by the rental company 50 is input. In the server 51 of the rental company 50, various data of the hydraulic excavator is recorded in association with the rental ID number.
In the above description, the rental ID number and the excavator ID are input, but both IDs are stored in the database 42 in association with each other. Therefore, the following may be also possible: for example, when a request for data extraction from the rental company 50 is made, only the rental ID is input, and all data of the corresponding hydraulic excavator is transmitted to the server 51 of the rental company 50. Further, all the service personnel may input only the hydraulic shovel ID when transmitting the inspection information.
According to the above steps, the inspection result of the hydraulic excavator 10 can be promptly transmitted to the manufacturer 40. Therefore, the efficiency of the inspection process can be improved without requiring troublesome work such as filling in a sheet inspection table and inputting the contents thereof from a terminal as in the past. In addition, since the inspection information can be stored in the database of the manufacturer 40 regardless of whether the inspector is the serviceman of the manufacturer 40 or the rental company 50, the inconvenience that the manufacturer 40 cannot grasp the inspection information of the serviceman of the rental company 50 can be eliminated.

Next, a 3 rd embodiment of a data input/output system to which the present invention is applied to a hydraulic excavator will be described with reference to fig. 13 to 16.
In this system, the data stored in the hydraulic excavator 10 can be read out using the mobile phone 20, and the data recorded in the hydraulic excavator 10 can be rewritten. By using the online service mode described in embodiment 1 as well, it is possible to transmit and receive information between the mobile phone 20 and the center server 41 (see fig. 1) of the center server 41 (see fig. 1). The specific configuration is described below.
Fig. 13 is a block diagram showing a control system of the hydraulic excavator and the mobile phone. The same reference numerals are used to describe the same portions as those in fig. 2 and 3.
A sensor group 12 is connected to a main control unit 11 mounted on the hydraulic excavator 10. The sensor group 12 is constituted by, for example, pressure sensors for detecting pump pressure and control pressure, temperature sensors for detecting engine cooling water temperature and operating oil temperature, and the like. The main control unit 11 controls a timer, not shown, based on the detection outputs of the sensors, measures the excavation time, the travel time, the rotation time, the engine operating time, and the like, and detects the presence or absence of an abnormality in each part. The detected data is stored in the memory 11A in the main control unit 11. Further, the external input/output interface 113 connected to the main control unit 11 is provided with a connection port 113a for cable connection to the mobile phone 20.
The portable telephone 20 is basically the same as that shown in fig. 3. The CPU21 is connected to the communication unit 122, the memory 26, the operation unit 24, and the display unit 25, and has a CPU 21. The operation keys 24a such as numeric keys provided in the operation unit 24 are normally used for inputting telephone numbers, but are used for rewriting data of the excavator 10 in a data input mode described later. The liquid crystal display 25a provided in the display unit 25 is generally used for displaying date and telephone number, but is used for displaying data from the hydraulic excavator 10 and data from the manufacturer 40 in a data input/output mode described later. Further, the external input/output interface 126 connected to the CPU21 is provided with a connection port 126a for cable connection to the hydraulic excavator 10.
The mobile phone 20 of the present embodiment can select the following 3 modes.
(1) Normal telephone (communication) mode
(2) Online service mode
(3) Data input/output mode
The phone mode is used for contact with manufacturer 40 or other interested parties. The online service mode is a service mode for a mobile phone, which is implemented by a telecommunications carrier or the like, and enables internet connection, transmission of mail, and the like via an online service company and a general communication line. In the present embodiment, the manufacturer 40, which is the base station, is accessed to the website and transmits data, or conversely, receives information from the manufacturer. The data input mode is a mode for transmitting and receiving data to and from the hydraulic excavator 10, and the details thereof will be described later. These mode selections and the like are operated by the operation unit 24.
A specific example of the data transmission/reception process will be described below with reference to the flowcharts of fig. 14 and 15. This process is possible by incorporating dedicated software into the mobile phone 20.
Fig. 14 and 15 show steps of control of the CPU21 of the mobile phone 20. Here, the connection port 126a of the mobile phone 20 and the connection port 113a of the hydraulic excavator 10 are connected by the cable CB, and the various data described above are stored in the memory 11A of the hydraulic excavator 10.
In fig. 14, first, it is determined which of the 3 modes is set (step S210). When the telephone mode is determined, normal telephone processing is performed (detailed description is omitted). When it is determined as the data input/output mode, the operation of the operation unit 24 is awaited (step S220). When the data input operation is performed, the data (the excavation time, the travel time, the rotation time, the engine operating time, and the like) stored in the memory 11A of the excavator 10 is input to the mobile phone 20 through the cable CB (step S230). The inputted data is stored in the receiving unit 23 (step S240). The stored data is converted into a displayable format and displayed on the liquid crystal display 25a of the display unit 25 (step S250).
On the other hand, when the data output operation is performed in the data input/output mode, a signal corresponding to the operation is transmitted to the main control unit 11 of the excavator 10, and the main control unit 11 rewrites data in the memory 11A in accordance with the operation (step S260).
This is explained in more detail below.
The main control unit 11 mounted on the hydraulic excavator 10 shown in fig. 13 also stores control programs such as trajectory control provided at the front portion of the hydraulic excavator, interference prevention control for preventing interference between the front portion and the cab, and the like. When such control is performed, data on the shape of the boom, arm, bucket, and the like is required for calculation. Therefore, the data regarding the data of the shape and the like described above is stored in the main control unit 11. The hydraulic excavator 10 may perform work by, for example, replacing a long arm with a wide bucket or replacing the arm with a wide bucket, depending on the work content. In such a case, it is necessary to rewrite data about the shape of the front member stored in the main control unit 11. When the output mode is selected in step S220 in fig. 14, first, the data to be rewritten among the data stored in the main control unit 11 is read, displayed on the display unit 25, rewritten on the screen by the operation unit 4, and stored in the main control unit 11 again (step S260).
As described above, in the present embodiment, the data stored in the memory 11A of the hydraulic excavator 10 can be extracted to the mobile phone 20, and the data in the memory 11A of the hydraulic excavator 10 can be rewritten by the operation unit 24 of the mobile phone 20 instead of the keyboard. A plurality of numeric keys 24a used by the telephone mode are provided on the operation unit 24. By using these keys 24a, the numerical data can be easily changed. When rewriting data, the original data and the rewritten contents can be displayed in order on the display unit 25 of the mobile phone 20.
However, the data extracted to the receiving unit 23 of the mobile phone 20 is raw data without any processing, and it is not always easy to grasp the contents. Therefore, in order to display more intuitive information, the data may be sent to an appropriate department for a while, processed there, and then sent back. The department that processes data may be, for example, the manufacturer 40.
To transmit data to the manufacturer 40, the portable telephone 20 is switched to the online service mode. In this case, the process proceeds from step S210 to step S270 of fig. 15, and when the data processing request operation is performed, the data in the memory 23 is transmitted from the communication unit 22 in step S280. The transmitted data is sent to the center server 41 of the manufacturer 40 via the online service company 30 and the communication network 60.
In the center server 41 of the manufacturer 40, when data is received from the mobile phone 20, the data is processed in a predetermined manner and then transmitted. The transmission data is sent to the mobile phone 20 via the online service company 30 and the communication network 60.
When the mobile phone 20 receives data (processed data) from the center server 41 (step S290), the data is displayed on the liquid crystal screen 25a (step S300). This display is easier to view than the original data, as compared with the case where the data is imaged or tabulated as shown in fig. 16.
The data may be easily visualized, and the center server 41 may analyze the data and send the analysis result to the mobile phone 20 for display. The data in the claims are processed to also include concepts of such analysis. Further, when data is transmitted from the mobile phone 20 to the manufacturer 40, a processing method may be designated, and the manufacturer 40 (center server 41) may process the data according to the processing method and return the processed data. Alternatively, software for processing data may be loaded into the mobile phone 20 instead of processing data by the manufacturer 40. In addition, software for processing data may be incorporated into the mobile phone 20. In addition, software having a function of transmitting data only to the manufacturer side may be loaded. Thus, for example, when data relating to a specific hydraulic excavator 10 is used by the manufacturer 40, the data is communicated by contacting a person on the site, so that desired data relating to the hydraulic excavator 10 can be quickly grasped.
Data transmission and reception between the mobile phone 20 and the main control unit 11 may be wireless communication such as infrared communication.
Industrial applicability
The present invention is also applicable to a method (system) for checking construction machines (e.g., cranes) other than hydraulic excavators and a method (system) for transmitting and receiving inspection information. Although various data of the hydraulic excavator are extracted by the mobile phone, the present invention is also applicable to extraction of various data of other construction machines such as a crane.
