Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically measuring the amount of suction pumped by a suction type pumping truck.

In some cases, human waste from each household is collected using a suction-type pumping truck commonly called a bakiyum car. After the work is completed, the amount of water pumped is usually measured visually and a fee is charged.

However, since it is carried out visually, there is often distrust among households, which can easily become a source of conflict.

The purpose of this invention is to improve the above-mentioned problems and to provide an automatic measuring device for a suction type pumping truck that enables accurate billing by measuring and printing the pumping amount.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

While printing the value shown in 4a on the prescribed paper,
This printing device selects and prints inputs 21Ea, 21Fa and input A when input P is "L", and selects input B when input P is "H".

Next, the operation of the embodiment will be explained.

After turning on the power switch (not shown), when the operator presses the "car" button 14A, the priority storage device 17 is set and the gate circuit 19A is opened. Number button 15A corresponding to the car management number
When you press 15J, the number changes to 2 on encoder 18.
It is converted into a base number and stored in the register 21A, and an output 21Aa is generated and displayed on the vehicle management number display 2. If you press the wrong number, press the "delete" button 15K and the AND gate 2
The output of 0A becomes "H" and the contents of the register 21A are reset to zero, so enter the numbers again using the number buttons 15A to 15J. This operation is the same for the other data selection buttons 14B to 14H. From then on, "year", "month", "day", "hour"
,
After pressing the "minute" buttons 14B-14D, 14G, 14H, if you press the number buttons 15A-15J,
Each number is displayed on indicators 3-5, 8, and 9. The counter 23 updates the minute every time it counts the pulse signal 22, and when it reaches 60 minutes, the counter 24 updates the hour. As a result, the current hour and minute are displayed on the displays 8 and 9.

When you arrive at each home, press the ``Ward'' button 14E and the ``World'' button 14F, then press the number button 1.
When 5A to 15J are pressed, the ward number and household number are displayed on the displays 6 and 7, respectively, in the same way as above.

To start pumping work, press the "Start" button 14I.
When is pressed, the memory 28 is set, the output Q becomes "H", and about 5 seconds later the output of the timer 29 becomes "H". During this time, when the pump truck stops,
The liquid level in the tank is oscillating, so this is to wait until the oscillations subside. timer 29
When the output of the monostable element 31 becomes "H", the output of the monostable element 31 becomes "H" for several tens of milliseconds, and the gate circuit 35 is opened. On the other hand, a measuring device 33 measures the liquid level in the tank, and a converting device 34 converts this into a volume. This value is gate circuit 3
5 and is set in register 37. After completing the work, when the "end" button 14J is pressed, the memory 28 is reset, the output Q becomes "L", and the output becomes "H". When the output becomes "H", the output of the timer 30 becomes "H" about 5 seconds later. During this time, the pumping operation is performed by vacuum suction, and the liquid level in the pumping tank fluctuates, so the purpose is to wait for the fluctuation to settle down. When the output of the timer 30 becomes "H", the output of the monostable element 32 becomes "H" for several tens of milliseconds, and the gate circuit 36 is opened. Also,
The output of the monostable element 26 remains "H" for several seconds,
The output of the OR gate 27 also becomes "H". with this,
The volume converted to the liquid level after pumping is set in the register 38 through the gate circuit 36. Then, the total amount pumped out is displayed on the display 10 based on the output of the register 38. Further, the divider 42 calculates the total number of unit containers of the total amount to be pumped, and displays the result on the display 11. On the other hand, the subtractor 39 calculates the difference between the volume before the start of work and the volume after the end of work, that is, the amount to be pumped out for one time, and is displayed on the display 12. Also, the divider 41 calculates the number of pipes to be pumped for one time, and the display 1
3. At this time, since the output of the monostable element 25 is "L", the printing device 43 selects the input A, and the number of sheets scooped out for one time is printed on a predetermined sheet of paper. At the same time, the vehicle management number, year, month, day, hour, minute,
Ward number and household number are also printed. A bill with these printed is issued from the bill issuing port 16. The above-mentioned operations are performed every time work is performed in each household.

When the collection tank is full, the user presses the "total" button 14K before going to the human waste treatment plant for disposal. with this,
The output of the monostable element 25 becomes "H" for several seconds,
Since the output of the OR gate 27 becomes "H" and the input P of the printing device 43 becomes "H", the printing device 43 selects the input B, and the total number of collected sheets is printed on a predetermined paper.

Note that it is also possible to implement as follows.

(A) Press number buttons 15A to 15J for "car" and "year"
"Month", "Day", "Hour", "Minute" buttons 14A to 14D,
Provided every 14G and 14H.

(B) There is no limit to the number of data selection buttons 14A to 14K.

(c) The content of the printout is not limited to the examples.

(d) Print out the charges.

(e) Do not use the "start" and "end" buttons 14I, 14J,
It is configured to issue signals to start and end work in conjunction with the operation of the suction pump of the scooping truck.

(F) Instead of calculating the difference before and after the collection, calculate the difference between the value measured at the previous household and the value measured at the next household after collection.

(g) As the measuring device 33, a float type, an ultrasonic type,
Microwave type, flowmeter type, pressure type, photoelectric type, electromagnetic type, etc. are used.

(H) Record each measurement result on magnetic tape, etc., and input it into a separate computer to save time and effort in administrative processing.

(e) Instead of inputting data using the data selection buttons 14A to 14K, the data is input using a magnetic card, voice, or the like.

(j) All processing is done by computer.

(S) The displays 2 to 13 are not limited to this.

(b) Use automatic broadcasting in addition to displays 2 to 13.

(S) Instead of entering the year, month, and day every day, use a perpetual calendar and enter only the initial set manually.

(C) The ward number and household number should be memorized in advance, and the collection should be carried out in that order.

(S) All equipment except measuring instrument 33 will be installed in the driver's seat and will be removable.

(t) Use a method that measures the weight of the entire tank.

As explained above, in this invention, the human waste pumping truck is provided with a device for inputting data to be printed, such as date, etc., the amount pumped in the pumping tank is measured, the amount pumped for one time is calculated, and the above-mentioned input is performed. In addition to printing the input data from the device and the amount pumped per batch, calculations are started after the fluctuations in the liquid level have subsided at the start and end of pumping, so accurate measurements can be used to bill accurate charges. It is possible to eliminate disputes caused by visual measurements.
