、図示しない焼却炉などの処理装置へ送られる。Currently, municipal waste generated from households is generally collected by truck and incinerated. However, the method of collecting waste by truck every day causes traffic pollution, so recently vacuum transportation of waste has been considered.
FIG. 3 shows a general vacuum transport device for waste developed to meet these demands. That is,
Collect ←^, -re ^', one + ^ Ha' fumi (-
Cι, -5 (As a matter of fact, the branch pipes 9 and 9' are provided with garbage inlets 11 and 11', fall prevention valves 5 and 5', and discharge valves 6 and 6'. The dust collector 12 is connected to the blower 1.The blower 1 is provided with a suction valve 2 and a discharge valve 3 on the suction side and the discharge side.On the other hand, the dust collected by the dust collector 12 The garbage is stored in a garbage bunker 10 via a double discharge valve 7, and sent to a processing device such as an incinerator (not shown).

変化する。FIG. 2 shows the control system of this garbage vacuum transport device. That is, a collection interval is set 21 at a pin port of the control system (not shown in FIG. 2), and when the set time 22 is reached, a collection preparation command 23 is output.
Then, the blower 1 is activated 24 to suck the air inside the collection pipe 8 and create a negative pressure inside. At the same time, opening the air intake valve 4 at the end of the line creates an air flow. Therefore, the discharge valve 6 of the input port 11, 11' where you want to collect the garbage
, 6' is selected 25, and ``Open'' is set to 26, the input J
The dust in the ports 11 and 11' is vacuum-suctioned through the collection pipe 8, collected by a dust collector 12, and collected in a dust bunker 10. However, the amount of waste varies depending on the weather, season, day of the week, etc.

に基づいて説明する。Therefore, it is actually extremely difficult to change the settings of the pin board according to these various amounts of change, and it is not easy to realize smooth collection intervals.
The present invention uses a waste amount prediction model to compare the predicted value and the actual value, change the collection interval and select the discharge valve according to the amount of change, and optimize the vacuum transportation equipment that eliminates the above-mentioned drawbacks. The purpose is to provide a control method. The present invention will be described below based on an embodiment shown in the drawings.

測モデルによつて、予測値３２が算出される。In FIG. 1, the amount of garbage thrown into the garbage input ports 11, 1'' is measured as follows.Since the vacuum transportation device for garbage is one that conveys the garbage through the pipe by air flow, It is necessary to limit the size of objects.Therefore, garbage inlet 1
1, 1" has a structure in which items of a certain size or less are thrown in each time. Therefore, by counting the number of times the waste inlet is opened and closed, the amount of garbage stored in the waste inlet (process Figure 3 shows a block diagram of a prediction model that calculates the predicted value, and the estimated value calculated above is input to a computer (not shown) as a process value 3L, and the predicted value is calculated by the prediction model. A value of 32 is calculated.

以上のゴミ滞量のある回路を一律に選択する。Next, as shown in Fig. 4, the calculated predicted value P and the set value Q are compared, and if P-Q>O, the collection interval is shortened, and if P-Q=O, the collection interval is unchanged, and furthermore, P
- If Q<0, extend the collection interval. For example, the setting of 1 time/day may be shortened to 1 time/day, or 2 times/day.
Extend to 1 day. However, the accuracy of the prediction model also determines the collection interval. Therefore, as shown in Figure 3, the process value 3 input in chronological order is
1, sequential identification of autoregressive models is performed using Kalman filter theory. This allows us to predict the amount of waste and
As shown in the figure, a prediction model can be used that takes into account the difference between the actual value and the predicted value as much as possible. On the other hand,
The process value, the predicted value P, and the deviation of the set value Q are also input to the selection circuit of the discharge valves 6, 6'', and the circuits in which the accumulated amount of dust is greater than the specified value are uniformly selected.

方式を提供てきる。Alternatively, priority is given to the circuit with a large amount of accumulated dust, and the simultaneous collection capacity of the collection pipe 8 is selected. This eliminates collection accumulation at the input port, keeps the garbage vacuum ready for use at any time, and at the same time ensures efficient operation of the garbage vacuum transport device. Next, when the collection interval is reached, a collection preparation command is issued and the blower 1 is started. After the blower has been started, the selected discharge valves 6, 6 are opened, and the thrown garbage is finally collected in the garbage bunker 10.
In this way, according to the present invention, even if the amount of waste changes,
We will provide an optimal control system that can perform vacuum transport that responds quickly to changes.
