Therefore, an analog digital conversion device 14 for converting the analog weighing signal S ₄ obtained by measuring the weight of the vehicle, that is, the garbage collecting vehicle V ₁ into a digital weighing signal S ₄ ^* and outputting the digital weighing signal S ₄ ^* to the input / output device 13. , The first and second input terminals are connected to the second and third output terminals of the input / output device 13, respectively, and the third input terminal is connected to the output terminal of the storage device 16; The output terminals are connected to the input terminal of the storage device 16 and the input terminal of the route indicator 17, respectively, and process the identification mark signal S ₂ and the digital measurement signal S ₄ ^* given from the input / output device 13 to process the storage device. 16 and hold the route instruction device S toward the route indicator device 17. _And an arithmetic unit 15 for outputting ₅ .

(Operation of First Embodiment)

Further, the operation of the first embodiment of the vehicle identification device according to the present invention will be described in detail with reference to FIGS.

When the vehicle, that is, the garbage collection vehicle V ₁ collects the garbage in the area in charge (for example, a residential area) and arrives at the garbage incinerator, it enters along the vehicle passage as indicated by the arrow X ₁ and instructs the route. According to the instruction of the device 17, the measuring device C is temporarily stopped.

The weighing device C is a vehicle, that is, a garbage collection vehicle V.₁ When it stops, its weight (that is, the garbage truck V₁ Weight and garbage truck V₁ The total weight of the garbage loaded in the container and the total weight) are measured and the analog weighing signal S_Four Is given to the analog-to-digital converter 14. The analog-to-digital conversion device 14 uses the analog weighing signal S supplied from the weighing device C. _Four The digital weighing signal S_Four ^*To the input / output device 13.

When the input / output device 13 receives the digital weighing signal S ₄ ^* from the analog-digital converter 14, it generates an image processing command signal S ₃ and supplies it to the image processing device 12.

The image processing device 12 uses the image processing command signal S₃ According to the image signal S from the image pickup device 11. ₁ Receives and processes the image signal S₁ Content (that is, the identification mark M₁), The identification signal S₂ Is output to the input / output device 13.

The input / output device 13 supplies the digital weighing signal S ₄ ^* supplied from the analog-digital conversion device 14 and the identification marker signal S ₂ supplied from the image processing device 12 to the arithmetic device 15.

The arithmetic unit 15 compares the identification mark list S ₇ read by giving the read command S ₆ to the storage unit 16 and the identification mark signal S ₂ to identify the vehicle, that is, the garbage collection vehicle V _1, and then move on to the course. A route instruction command S ₅ is given to the instruction device 17 to instruct the vehicle, that is, the garbage collection vehicle V ₁ to approach one of the plurality of garbage incinerators. As a result, the vehicle, that is, the garbage collection vehicle V ₁ can be distributed to a plurality of garbage inlets in the garbage incineration pit, which in turn collects the garbage collected in a specific area at a specific garbage inlet in the garbage incineration pit. This can be avoided, and as a result, the waste incineration efficiency or life of the waste incinerator can be improved.

The arithmetic unit 15 also obtains the weight of the trash carried by the trash collection vehicle V ₁ from the content of the digital weighing signal S ₄ ^* , and writes it as the weighing data S ₈ together with the write command S _9. It is given to the storage device 16 and held at an existing location of the storage device 16. This makes it possible to record and hold the amount of garbage collected by the garbage truck V ₁ or the amount of garbage collected from the area covered by the garbage truck V ₁ .

Garbage truck V₁ Is indicated by the arrow X from above the weighing device C according to the instruction of the route instruction device 17. ₂ When you move to the garbage incinerator as shown in, the analog weighing signal S_Four As a result, the digital weighing signal S_Four ^*Is no longer given to the input / output device 13, the input / output device 13 receives the image processing command signal S₃ Is not given to the image processing device 12. As a result, the image processing device 12 receives the image signal S from the imaging device 11.₁ It stops receiving and processing the identification signal S for the input / output device 13.₂ Will not give. Therefore, the input / output unit 13 sends the digital weighing signal S to the arithmetic unit 15._Four ^*And the identification signal S₂ Will not give. The arithmetic unit 15 is used for the subsequent garbage collection vehicle V.₁ For the direction instruction command S to stop on the weighing device C_Five Is given to the route indicating device 17 to display a stop instruction, and the robot stands by.

(Second Embodiment)

In addition, the configuration and operation of the second embodiment of the vehicle identification device according to the present invention will be described in detail with reference to FIG.

In the second embodiment, a license plate is used as an identification mark M ₂ for identifying a vehicle (for example, a passenger vehicle V ₂ ) and a switch plate D is used instead of the weighing device C. Except for this, the structure is substantially the same as that of the first embodiment.

Therefore, here, by assigning the reference numeral given to the member corresponding to the member included in the first embodiment to the reference numeral added to the first embodiment by “10”, Detailed description of other configurations will be omitted.

In the second embodiment, when the vehicle, that is, the passenger vehicle V ₂ moves as shown by the arrow Y ₁ and depresses the switch plate D, the stepping signal S ₄ ^** is generated from the switch plate D. Are provided to the input / output device 23. The input / output device 23 generates an image processing command signal S ₃ according to the stepping signal S ₄ ^** , and supplies it to the image processing device 22.

The image processing device 22 uses the image processing command signal S₃ According to the image signal S from the image pickup device 21. ₁ Receives and processes the image signal S₁ Content (that is, the identification mark M₂), The identification signal S₂ And outputs to the input / output device 23.

The input / output device 23 provides the identification device signal S ₂ provided from the image processing device 22 to the computing device 25.

The arithmetic unit 25 compares the identification sign list S ₇ read by giving the read command S ₆ to the storage unit 26 and the identification sign signal S ₂ , identifies the vehicle, that is, the passenger vehicle V _2, and determines the identification result. The identification data S ₅ ^* is given to the subsequent device (for example, a billing device). This makes it possible to determine that a particular vehicle has passed a certain point (for example, a parking lot or a toll road gate).

The arithmetic unit 25 also gives the identification result as the identification data S ₈ together with the write command S ₉ to the storage unit 26, and causes the storage unit 26 to hold the identification result. This makes it possible to record information about a specific vehicle.

When the vehicle, that is, the passenger vehicle V ₂ moves from the switch plate D as indicated by the arrow Y ₂ , the stepping signal S ₄ ^** is not given to the input / output device 23, so that the input / output device 23 performs image processing. The command signal S ₃ is no longer given to the image processing device 22. Along with this, the image processing device 22 stops receiving and processing the image signal S ₁ from the imaging device 21, and does not give the identification marker signal S ₂ to the input / output device 23. Therefore, the input / output device 23 does not give the identification mark signal S ₂ to the arithmetic unit 25.
