DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 shows a first embodiment of an operating number management system according to the present invention. A hydraulic excavator as a construction machine is equipped with a so-called mechatronic system that electronically controls the entire machine body. .
[0019]
In the figure, the operating number management system includes an operating information detecting device 1 configured by a microcomputer mounted on an upper swing body of a hydraulic excavator, and an operating information communicating device 2 connected to the operating information detecting device 1 by serial communication. The operation information management device 5 mainly communicates with the operation information communication device 2 through the communication satellite 3 and the base station 4, and this operation information management device 5 is a wide area rental company or a construction machine. It consists of a host computer installed in the manufacturer.
[0020]
A key switch unit 6, an alternator 7, a fuel sensor 8 and a pressure sensor 9 are connected to the input side of the operation information detection device 1. Then, when the engine key 6 a is inserted into the key switch unit 6 and switched from the “LOCK” to the “ON” position, the power of the battery (not shown) is supplied to the operation information detecting device 1. Subsequently, when switching to “START”, the engine of a hydraulic excavator (not shown) is started.
[0021]
When the engine is started and a power generation signal is output from the alternator 7, the operation information writing unit 1a stores the engine start date and time in the operation information memory 1b. When the engine is stopped and no power generation signal is output from the alternator 7, the operation information writing unit 1a stores the engine stop date and time in the operation information memory 1b.
[0022]
Further, the accumulated operation time of the hydraulic excavator measured by the hour meter 1c provided in the operation information detection device 1 and the remaining amount of fuel output from the fuel sensor 8 are also stored in the operation information memory 1b.
[0023]
The pressure sensor 9 detects the operation pressure of, for example, the excavation attachment of the hydraulic excavator. When a signal is output from the pressure sensor 9, the excavation work is actually performed. Therefore, the time is started when the power generation signal is output from the alternator 7 and the signal is output from the pressure sensor 9 as the work start time, and the time is measured when the signal from the pressure sensor 9 is lost. Stop. Thereby, it is possible to count the working time when the work is actually performed. In the above embodiment, the operation pressure of the excavation attachment is detected by the pressure sensor. However, the present invention is not limited to this, and the operation pressure can also be detected by using a pressure switch instead of the pressure sensor. In the above-described embodiment, the excavation attachment is described as an example of the operation pressure detection target. However, the present invention is not limited to this, and the operation pressure such as traveling and turning may be detected.
[0024]
In addition, each structure of the operation information detection apparatus 1 mentioned above is integrated in the mechatronics system conventionally for the purpose of controlling a hydraulic excavator.
[0025]
The operation information in the operation information memory 1b is output to the communication processing unit 1d, and this communication processing unit 1d is connected to the communication processing unit 2a of the operation information communication device 2. The operation information transmitted to the communication processing unit 2a is read by the operation information reading unit 2b and transmitted to the communication satellite 3 via a transmission unit (transmission means) 2d and an antenna 10 described later. The transmission unit 2d is connected to an identification information memory 2e that stores identification information unique to the hydraulic excavator. When transmitting the operation information, the identification information is added to the operation information and transmitted. ing.
[0026]
The excavator is equipped with a GPS (Global Positioning System) that is a global positioning system. As is well known, GPS is a high-accuracy positioning system that receives transmission data from at least three artificial satellites with a receiver on the earth and measures the three-dimensional position of the receiver from the received data. In the embodiment, the positioning device 2g measures the position of the hydraulic excavator based on the transmission data from the GPS antenna 2f, and transmits the positioning information via the transmission unit 2d as necessary.
[0027]
The operation information management device 5 that receives the operation information (which may include positioning information) through the communication satellite 3 and the base station 4 includes a receiving unit (reception unit) 5a that receives the operation information, and the received operation information. An operation information writing unit 5c that writes to the operation information storage unit 5b, an operation information editing processing unit 5d that reads and edits necessary information from the operation information storage unit 5b according to a program stored in advance, and an editing process An editing result storage unit 5e for storing the result, a graphic processing unit 5f for converting the editing result into graphic data, and a display device comprising a CRT by combining the converted graphic data with the map data read from the map data memory 5g 11 is composed mainly of a composite display section 5h for overlay display on the screen.
[0028]
The display device 11 functions as a map data output unit, and the operation information editing processing unit 5d, the graphic processing unit 5f, the map data memory 5g, and the composite display unit 5h function as an operation number data output unit. The operation information editing processing unit 5d functions as an operation number calculation unit.
[0029]
Next, the configuration of each part of the operation information management apparatus 5 will be described.
[0030]
The operation information writing unit 5c identifies the rental machine number based on the received identification information of the operation information. If the corresponding rental machine number exists in the operation information storage unit 5b, the operation information writing unit 5c takes in the operation information. Discard.
[0031]
As shown in FIG. 2, the operation information storage unit 5b has storage columns such as “use date”, “start time”, “end time”, “working time”, “rental area” for each rental machine number. These operating information are stored sequentially over time. For example, rental machine number SK60-0001 was rented to Asanan Ward, the engine was started at 8 am on March 1, 2000, the engine was stopped at 11:15 am, and the work was done for 3 hours and 15 minutes. Is remembered. The rental area is entered by the rental company administrator at the time of rental.
[0032]
The operating information editing processing unit 5d calculates the number of operating units based on the operating information accumulated in the operating information storage unit 5b, accumulates the operating units for each rental destination rental area, and stores them in the editing result storage unit 5e. .
[0033]
FIG. 3 shows the contents stored in the editing result storage unit 5e. Rental machines are classified for each rental area, and further classified by class (SK60, SK70, SK75, SK100, SK115, Rental machines are stored together in SK235). For example, in Asaminami-ku, rental model SK60 has six, SK70 is 2 Tai稼働中, the accumulation of their running time is made to each 40 hours and 10 hours. In addition, coordinate information (in the case of graphic display) for displaying these accumulated operation number and accumulated operation time on a map is also stored.
[0034]
The graphic processing unit 5f executes any one of the display forms shown in a) to f) below based on the operation information stored in the editing result storage unit 5e.
[0035]
a) Cumulative operating number display by color coding or pattern White for regions where the number of operating units is less than 10 units / month, yellow for regions where 10 units or more and less than 20 units, and green for regions where 20 units or more and less than 30 units The cumulative operating number is displayed by region by displaying blue on regions with 30 or more and less than 40 units and red on regions with 40 or more and less than 50 units.
[0036]
If the display device 11 is monochrome display, instead of color-coded display, for example, as shown in FIG. Can be displayed separately.
[0037]
b) Cumulative operation number display by graph Figure 5 shows the three-dimensional display of the cumulative operation number of rental machines in each region in a bar graph, and the height of each bar graph classified by model (SK60, SK70 ...) It corresponds to the cumulative number of units in operation.
[0038]
If the graphic display is made in this way, it is possible to grasp at a glance how many rental models are operating in which region.
[0039]
c) Display of Cumulative Operating Number by Graphic FIG. 6 shows the cumulative operating number displayed on the hydraulic excavator in the form of a graphic, and the size of each hydraulic excavator corresponds to the cumulative operating number. For example, in the figure, the largest excavator a has a cumulative operating number of 20 or more and less than 30 units / month, the intermediate size excavator b has 10 to less than 20 units / month, and the smallest excavator c has a size of 10 Indicates less than a unit / month.
[0040]
Further, FIG. 7 uses a hydraulic excavator which is made into a graphic as in FIG. 6, but the cumulative number of operating units is represented by the boom undulation angle. In the figure, d is the cumulative operating number of 40 to less than 50 units / month, e is 30 to less than 40 units / month, f is 20 to less than 30 units / month, g is 10 to less than 20 units / month, h indicates less than 10 units / month.
[0041]
When the size of the size shown in FIG. 6 is classified by class of the hydraulic excavator and combined with the graphic display of FIG. 7, the cumulative operating number can be displayed by class.
[0042]
d) Three-dimensional cumulative operation number display Each region on the map is displayed three-dimensionally. Specifically, the map is shown in perspective on the screen, and the region is raised by rental area according to the cumulative operation number. To display the cumulative number of units in operation. In this case, it is preferable to make the raised height proportional to the cumulative operating number.
[0043]
e) Cumulative operation number display by dynamic display As shown in FIG. 6, the hydraulic excavator class can be represented by the graphic size of the excavator, and the accumulated operation number can be represented by the moving speed. In order to express this movement speed on the screen, for example, the excavator is repeatedly moved in the horizontal direction within the rental area, high speed movement indicates that there are many cumulative operating units, and low speed movement indicates that there are few cumulative operating units. What should I do?
[0044]
Alternatively, it can also be expressed by the amount of smoke (designed) blown out behind the excavator.
[0045]
f) Display of changes in cumulative number of operating units In each of the above display forms, the current cumulative operating unit number is only displayed, but the progress of the operating unit number in the rental area is displayed. It may be configured.
[0046]
For example, if the changes in the number of operating units in a certain rental area are displayed in stages using a graphic hydraulic excavator, the changes in the number of operating units can be grasped at a glance.
[0047]
4 to 7 show an example in which the cumulative operating number is displayed only in a specific region. However, the present invention is not limited to this. By switching the screen of the display device 11 to the entire map of Japan as shown in FIG. The cumulative number of units in operation can also be displayed by prefecture. If comprised in this way, for example, in a wide area rental company, it becomes possible to grasp | ascertain the operation state of the rental machine of the whole country at a glance, Therefore Operation management becomes easy.
[0048]
Next, FIG. 9 shows a second embodiment of the operating number management system according to the present invention. This embodiment is intended for a relatively small hydraulic excavator not equipped with a mechatronic system.
[0049]
Note that the operation information management apparatus 5 has the same configuration as that shown in FIG. Further, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.
[0050]
In FIG. 9, a key switch unit 6, an alternator 7, and a fuel sensor 8 are connected to the input side of the operation information communication device 12 added to the hydraulic excavator via a voltage converter 13. That is, the signal output from the input side device is converted into a signal that can be processed by the operation information communication device 12 including a microcomputer.
[0051]
When the engine key 6a is inserted into the key switch unit 6 and the engine of the hydraulic excavator is started and a power generation signal is output from the alternator 7, the operation information writing unit 12a stores the engine start date and time in the operation information memory 12b. When the engine is stopped and the power generation signal is not output from the alternator 7, the operation information writing unit 12a stores the engine stop date and time in the operation information memory 12b. Further, the remaining amount of fuel output from the fuel sensor 8 is also stored in the operation information memory 12b.
[0052]
The operation information reading unit 12c receives a time signal from the internal clock 12d, reads the operation information stored in the operation information memory 12b at a predetermined time, and transmits the transmission unit (transmission unit) 12e and the antenna 10 to each other. The operation information is transmitted to the communication satellite 3 via
[0053]
Reference numeral 12f denotes an identification information memory that stores identification information unique to the hydraulic excavator. When the operation information is transmitted, the identification information is added to the operation information and transmitted. As described above, a hydraulic excavator not equipped with a mechatronics system is newly equipped with an operation information communication device 12 having a function of collecting and transmitting operation information.
[0054]
Moreover, in each above-mentioned embodiment, although the cumulative operation number was displayed for every ward, not only this but it can also be displayed for every sales range of a rental sales office. Then, since it becomes possible to grasp the machine operation rate for a plurality of rental sales offices, it becomes possible to level the rental machines between the rental sales offices. In addition, the number of accumulated operating units may be displayed for each construction site.
[0055]
In this way, if the cumulative operating time is displayed for each area divided according to the purpose, it becomes possible to grasp the demand for rental machines for each area. For example, a plan for opening a rental office It can also be useful.
[0056]
Moreover, if this invention is used together with GPS, it becomes possible to perform more advanced operation state management. That is, if the current position of the hydraulic excavator in operation is displayed on a map displayed on the screen of the display device 11, the arrangement of the individual hydraulic excavators can be grasped. Therefore, even if there is a shortage of hydraulic excavators in Asanan Ward and replenishment from Saeki Ward, for example, it is easy to select a hydraulic excavator of the required class with a short travel distance to Asanan Ward. Will be able to.
[0057]
Further, if the movement of the hydraulic excavator is tracked using GPS, an abnormal action deviating from the work area can be checked, so that theft can be prevented in advance.
[0058]
In the above embodiment, the cumulative number of operating units is displayed as an overlay on the map. However, when a printing device such as an XY plotter is connected to the output device, it may be configured to print out.
