Then, the above-mentioned information regarding the cargo transported within the period designated by the operation of the keyboard 16B by the operator is determined based on the above date / time information, and the weight of the cargo is determined for each driver by the determined information. Add,
Calculate the total weight of the load carried by each driver within the above period. Similarly, the aggregating unit 16D also identifies the type of the cargo for each driver based on the information indicating the type of the cargo, adds all the weights of the cargo for each type, and each driver determines the above period. Calculate the total weight of the cargo carried inside the cargo for each type of cargo.

The display control means 16E displays the total weight of these loads obtained by the totalizing means 16D on the CRT monitor 16C in a predetermined format. Specifically, the display control means 16E

The cargo transportation manager can efficiently manage the cargo transportation work by looking at the display.

In the third embodiment, the information is transmitted to the host computer 16 via the floppy disk, but instead of using the floppy disk, the control computer 8 and the host computer 16 are directly connected by a cable. It is also possible to send information to the host computer 16. Further, it is possible to connect through a telephone line or the like, and in that case, the host computer 16 installed in a management office as a center collects information from the cargo weighing system 2 ″ installed in a remote place. However, the above-mentioned aggregation processing can be performed.

Further, in the first embodiment, the destination information is stored in the storage means 8C in association with the driver's identification information, but the load type is designated as in the second embodiment. In such a case, the destination may be stored in association with the type of cargo, and the destination may be designated according to the type of cargo. Further, when there is only one destination, the destination information does not need to be stored in association with the driver identification information, and only the information indicating the destination may be stored.

In each of the above embodiments, the ID
Although the card is an electromagnetically coupled ID card, other ID cards such as an optical remote control type ID card that transmits information held by light, an ID card that holds information by a bar code, etc. Can be used, and it is also possible to use a magnetic recording type D card. However, in the case of a magnetic recording type ID card, it is necessary to completely insert the ID card into, for example, the insertion hole provided in the operation panel 6, which is slightly inferior in operability. Further, the information holding means does not necessarily have to be a card type as in the above embodiment, and various shapes and sizes can be used within a range not inconvenient to carry.
