In general, a manure collection vehicle that collects manure from a manure collection tank of a building or a house that does not have its own purification facility is discharged to a manure treatment plant. The manure collection vehicle completes the work by sucking and transporting the manure into the manure storage tank through the manure hose connected to the vacuum pump and discharging it to the manure treatment plant. In the conventional method of measuring the amount of manure collection, after collecting manure using the manure collection vehicle, the operator visually checks the level gauge installed at the rear of the manure collection vehicle, calculates the manure collection amount, and charges the fee according to the collection amount on site. Workers are receiving cash directly.

However, this method causes a lot of errors due to a large number of errors due to the visual measurement of the workers, and it is difficult to calculate the billing for each house when the two or more houses are continuously collected by one vehicle. In addition, during the collection work at the inclined work place, if the collection amount exceeds a certain amount, it is impossible to calculate, and it was inevitable to charge according to the subjective judgment of the worker.

For example, when the capacitance of the collected manure 10a sensed by the water level detecting unit 120 is 311pF, the manure collection tank 10 calculated by the water level calculating unit 160 according to the lookup table information as shown in Table 1 above. The level of the collected manure (10a) of the inside is 605mm, at this time, the amount of manure accommodated in the manure collection tank 10 is 3800L.

The gap G becomes 71 mm, and the water level calculation unit 160 applies the gap G to the water level of the collection manure 10a detected by the water level detection unit 120, so as to actually collect the manure collection tank 10. The actual amount of collected manure stored inside can be calculated.

In step S5, the water level calculation unit 160, through the steps S2 to S4 as described above, the capacitance value, the temperature value and the manure collection tank 10 of the collected waste manure (10a) accommodated inside the manure collection tank 10 In consideration of the inclination value of), the first manure amount accommodated in the manure collection tank 10 before the manure collection is calculated and stored. Thereafter, the vacuum pump 21 is operated to introduce the manure into the manure collection tank 10.

In step S6, when the manure collection end button 185b is selected in the button unit 185 of the water level calculation panel, while the above-described step S2 to S4 proceeds, the manure collection tank 10 in accordance with the operation of the vacuum pump 21 After the second manure amount including the newly collected collection manure amount into the inside is calculated in the water level calculation unit 160 is stored, at this time, the water level calculation unit 160 is collected by subtracting the first manure amount from the second manure amount To calculate.

Subsequently, in step S7, the water level calculation unit 160 provides charges according to the collected manure amount and the collected manure amount to the water level calculation display unit 180.
