Further, in step S108 shown in FIG. 9, the work efficiency calculation process is executed, whereby the analysis results stored in the individual work efficiency file 60d3 (for example, the analysis results shown in FIGS. 10 and 11). And the work efficiency of the driver is calculated based on the work efficiency calculation formula prepared in advance in the program of the work efficiency calculation program file 60d1, and the calculated work efficiency is stored in the individual work efficiency file 60d3.

Therefore, as is clear from the above description, the work efficiency calculation processing in step S108 corresponds to the work efficiency calculation means described in the claims.

In step S109, the work efficiency screen display processing is executed, so that the work efficiency screen information for displaying the analysis result and the work efficiency stored in the individual work efficiency file 60d3 on the display device 62 is stored in the RAM 60.
c, and this work efficiency screen information is output to the display circuit 60f via the bus line B, and thereafter, step S110
Proceed to. Then, the work efficiency screen based on the work efficiency screen information is displayed on the display device 62 by the display circuit 60f. It is also possible to provide a print button or the like on the work efficiency screen and output the screen contents to the printer 80.

When it is determined that the display end request has not been received (N in step S110), the determination process is repeated to wait for the input of the display end request. On the other hand, when it is determined that the display end request has been received (Y in step S110), the process proceeds to step S111.

By executing the work efficiency screen erasing process in step S111, a work efficiency screen erasure request is output to the display circuit 60f via the bus B, and thereafter, the process returns to step S100 to repeat a series of processes.

If it is determined in step S102 that the selected data corresponds to the end of the selection screen (end in step S102), the process proceeds to step S112. Then, in step S112, by executing the selected screen erasing process, a selected screen erasing request is output to the display circuit 60f via the bus B, and then the process ends. Then, the selection screen displayed on the display device 62 is deleted by the display circuit 60f.

Therefore, as is clear from the above description, the CPU 60a of the personal computer 60 functions as the work efficiency calculating means described in the claims. The load information 52 having the load data 52b is stored in the memory card 5
As is clear from the fact that the data is stored in 0, in the first embodiment, the memory card 50 functions as load data storage means.

Next, an example of the operation (operation) of the first embodiment having the above-described configuration will be described with reference to the drawings.

When the memory card 50 is inserted into the card insertion portion 36 of the collection device 30 mounted on the vehicle 100 and the storage processing is completed, the sensor unit 20 responds to the load transmitted to the axle 2 in a concentrated manner. The distortion amount is measured, and the measurement result is input from the weighing scale 10 to the collection device 30 as the load data 52b.

The collecting device 30 monitors whether or not a change has occurred in the load based on the input load data 52b, and when a change in the load is detected (Y in step S5),
Detection time data 52a, travel distance data 52c, position data 52 when the change is detected in the load data 52b.
The load information 52 is generated by adding d and the like (step S6).

As described above, the load data 52b generated each time a change in the load applied to the vehicle 100 occurs is stored in the load information 5
By storing the load information 52 in the memory card 50 as 2, the load information 52 generated during one operation from departure to entry of the vehicle 100 is stored in the memory card 50 in chronological order.

The memory card 50 discharged from the collection device 30 after one day of operation is inserted into the reader / writer 70 of the analysis device 200 installed in a business office or the like. Then, on a selection screen displayed on the display device 62 according to the started work efficiency calculation program (step S100),
By selecting the selection process using the input device 61, the load information 52 and the like collected from the memory card 50 are added to the individual data file 60d2 corresponding to the driver who owns the memory card 52 (steps S103 to S1).
04).

On the selection screen displayed on the display device 62 according to the work efficiency calculation program started by the accountant on the closing date or the like, the analysis process is selected by the input device 61 so that the driver who performs the analysis can be provided. The load information 52 is obtained from the corresponding individual data file 60d2, the work state of the driver is analyzed from various viewpoints with respect to the load data 52b of the load information 52, and the work efficiency is calculated based on the analysis result ( Steps S105 to S10
8).

Work efficiency file 60d for each individual driver
The work efficiency screen indicating the work efficiency calculated in Step 3 is displayed on the display device 62 (Step S109). Thereafter, when a display end request is input by the input device 61 (Y in step S110), the work efficiency screen of the display device 62 is erased (step S111).

As described above, the load data 52b indicating the change in load generated in response to the unloading operation is added with the detection time data 52a indicating the detection time, and the load data 52b is added to the memory card (load data storage means) 50. By storing the data in time series and analyzing the load data 52b and the detection time data 52a, it is possible to analyze the time required for loading and unloading. Further, since the load is automatically measured by the sensor unit (load data generating means) 20, there is no need for the driver to measure the load of the luggage, and the driver's work load is not increased. Therefore, the work efficiency of the driver can be calculated based on the analysis result regarding the unloading work of the luggage analyzed from the collected load data 52b and the detection time data 52a.

Since the load is transmitted to the axle 2 in a concentrated manner, the load transmitted to the axle 2 is maintained even if the load is distorted or the friction occurs due to the unloading of the load or the running state of the vehicle 100. The moving range of the center becomes small, and the sensor 7
Since the amount of distortion of the axle 2 measured by the method becomes accurate, the accuracy of the load data 52b generated by the sensor unit (load data generating means) 20 can be improved. Accordingly, more accurate load data is stored in the load data storage means 14 and 50. By analyzing the load unloading work based on the load data, the calculation accuracy of the driver's work efficiency can be reduced. It can be further improved.

Further, since the traveling distance data 52c is added to the load data 52b stored in the memory card (load data storage means) 50, the loaded weight of the vehicle 100 and the traveling distance in that state are grasped. Therefore, it is also possible to analyze the driver's transportation results. Therefore, since the work efficiency of the driver can be calculated in consideration of the actual transportation performance, the work efficiency according to the work mode of the driver can be calculated.

Further, since the position data 52d is added to the load data 52b stored in the memory card (load data storage means) 50, the travel route and the unloading position of the vehicle can be determined based on the position data 52d. Since the transport route of the driver and the like can be grasped, it is possible to perform analysis in consideration of the transport route of the driver. Therefore, since the work efficiency can be calculated based on the analysis result in consideration of the driver's transport performance, the work efficiency according to the driver's work mode can be calculated.
