In the second embodiment, when the actual empty process S1 is started, first, a process S6 is performed. In processing S6,
The empty determination unit 22 determines whether or not the real / empty key has been set from the input unit 23. If an empty vehicle has been set, the process proceeds to step S4, and the empty / empty state is recorded in the real / empty recording unit 21.

If the actual / empty vehicle key is used to set the actual vehicle, the process proceeds to step S5 where the actual / empty recording section 21 records the actual vehicle state. If the actual / empty key does not set the actual vehicle or the empty vehicle, the process proceeds to the process S2 and the processes S2 to S5 are executed.

FIG. 7 shows a third embodiment of the actual / empty process S1. In FIG. 7, processes S2 to S6 correspond to FIGS.
As described in the above. In the process S7, the real / empty determination unit 2
In step S2, if an empty vehicle is set in step S6, the same processing as step S3 is performed, and if the determination is YES, the process proceeds to step S8 and an alarm is issued from the alarm unit 23.

In step S8, the actual / empty determination section 22 performs the same processing as step S3 when the actual vehicle is set in step S6, and moves to step S10 when the determination is NO, and proceeds to step S10. Raise more alarms. That is, in steps S7 and S8, it is determined whether or not the set of the actual / empty key matches the actual vehicle state, and an alarm is issued if they do not match.

In this embodiment, the determination of the actual vehicle / empty vehicle is made based on whether the weight is greater than the set value. However, the determination may be made based on whether the weight change is greater than the set value.
