Abstract

PURPOSE:To effectively monitor the leakage out of a water supply equipment by providing a water leakage detection means in the water supply equipment. CONSTITUTION:A water service meter 11 having a transmitter is used as a water supply volume detection means that outputs a detection pulse P1 at every predetermined water supply volume of the public water service into a water reservoir tank 3. An alarm device 12 is a water detection means, and consists of a microcomputer control section, ten keys for setting a standard water consumption volume and an indicator panel. The alarm device 12 counts the pulse P1 from th meter 11 and compares it with the reference water consumption, and if the reference consumption is exceeded, the indicator panel lets out an alarm to tell the leakage. In this manner, the water leakage in the water supply equipment in a building, etc. due to a failure of a flash valve in the toilet or neglect to turn off the tap, etc. can effectively be detected.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monitoring device for detecting water leakage in water supply equipment.

In general, in buildings, etc., there is a garden where a group of people can be used as a group, and a ditch for women's houses.

In other words, city water is delivered to the consumer (2) via the water meter (1).
) Water tank (4) equipped with a water level sensor (3)
Once the water is stored in the water supply pump (5), the water level sensor (
6) The amount of water is pumped into an attached overhead tank (γ) and placed under the natural tower to supply water to taps and toilets.

When the water is used at the tap or toilet, etc., the water level in the temporary tank (7) will drop. I am working on the water supply pump (5) purple 1, drive i 1J so that the water level is even.

By the way, in this J:f) water supply installation +f#,
If the flush valve in the toilet breaks down or the water tap forgets to turn on, causing water leakage, the water bill, sewage bill, and electricity bill for the water pump will increase. Become a hoda.

Moreover, the occurrence of water leakage is far more common than the occurrence of water pump failure in terms of the failure rate of the water supply equipment as a whole.

However, in the traditional setting of famous water, there was no rule of thumb for fire, water, etc.

The present invention has been developed based on the above-mentioned points. 1. Supervised by Suisetsu υtη who issues the report! The equipment is provided below.

Below are some examples of the present invention. ;js i'j Figure 1m 2nd
From the figure, I will explain the same (''1).In addition,
The same reference numeral 771j as in the first drawing is given the same reference numeral, and the explanation of the part 7 is omitted.

Figure 2 is a map showing the location of Mt. Ichifu of the present invention.

In the same figure, the 7 Qili person designation switch (1 (11 is set by the monitoring combination means, + Tsutomu) by Kansaku, Yoshiyo Naga (2
) or a black VC. My brother started supervising me with small equipment such as an easy-to-read table.
When the command 1 is issued, the switch is turned on, and when the command is given to end the monitoring, the switch is turned off.

') h 'Water with Ig device ↓ 1 meter (11j is the water supply amount/spring month, and the condensed amount of city water ht that is not supplied to the father water tank (8), for example 1e A detection pulse is output to the P-work every time.

One unit 2) is a water leak determination means, and as shown in FIG. 6, for example, a CPU (central processing unit) (121),
Program memory (ROMX122), data memory (
RAM) (j23), input interface (+24a)
~ (124c) and output interfaces (125a, (
j25b);
The amount of water supplied per unit hour T that occurs during the press conference (or this 7
1.A water volume 4] "cancer blooming pulse reference)" and monitoring cycle ("4" interval) Jt number setting numeric keypad (
126) and the display (j27
).

Then, based on the program stored in advance in the ROI side (122), this 6'-+ organ (chest) detects the state of the folding person designation switch (10), and after commanding the start of supervision, the estrous organ Count the 49S output pulse P from the attached water meter (11), measure the amount of cap water per sitting time T, and measure it every set monitoring cycle Δ to see if the water supply exceeds the set water supply or not. For groups whose measured water supply amount exceeds ¥2 water supply, ring the alarm bell +18) i.

Next, let's talk about the effect of this example, which was created in J:9!
The explanation will be made with reference to FIGS. 184 to 6t.

The initial settings of the δP11j device (12J) are explained with reference to FIG.

In the same figure: alarm (+21, 'power on',
j Azuma numeric keypad (126) k display (127)
Confirm the manual setting by inputting the 4yi output pulse corresponding to unit time (water supply per unit time n) during unattended operation (setting value). In addition to displaying 1 time A in table 7j< container (127), RAM
(123) is stored at 0. Part 1, the ξf is stored on the numeric keypad (126), and by inputting Δtγ, the input is fL7ζ, and Δt is RAM. (
126). Well, I'll supervise you, F Kru Δt,
Set a time V that is sufficiently shorter than the unit time T. For one evening, the unit is 11, the music T is 60 minutes, and the monitoring cycle Δt is 2 minutes.

Next, the 1st sign (12) will be explained with reference to Figure 5.

In the same figure, the convex two-alarm device (Raku) determines whether or not to start monitoring by checking the state of the first person estimation switch (10), and d2 at the start of monitoring, and f'L is the determination operation h. ” Set the unit time Tr in the start setting timer, start, and wait until time amp is completed.

Then, when the time is up, it is checked whether the count value CN of the pulse output P per unit time T measured by a measurement program (not shown) is greater than or equal to the set value A (CN≧A). I Determine whether or not the set water supply == exceeds the limit ζ.

If the result of this discrimination is the measured water supply amount〉Set foot connection and IL, then the number of cum count CN is the set value A and an is the bell [Ia
After ``f'il'', check the monitoring switch (io+τ) to determine whether the monitoring has ended or not, and continue to threaten the bell (13) τ to end the monitoring.

For this, the determination result is measured f18 water volume ≦ installation water supply agitation, and f'L is the count number clq (set value A
If so, the monitoring cycle Δt'6 is set in the monitoring cycle timer.
Set and start, determine whether the time amplifier supervisor/O6 has ended or not, and if the monitoring has not ended, turn on the unit time IFI again.
Blooming pulse per J T Enters a separate operation of 1A to determine whether the count number CN of the P work exceeds the set value h2.

This one benefit, glare! +1υ made by Gujian 1 tari? This will be explained with reference to FIG. In addition, in FIG. 6, the illustrated Ile platform, unit time T-60 minutes, set value A=3, and monitoring cycle Δt=4
．． It will be 75 minutes.

In the column of Fig. 6, the unattended designation switch shown in Fig. 6 (b) (LOl is on, the point in time when monitoring 1 = q start is commanded from tl to monitoring 1'll!, 1 side I/l-
Enters unit time 1tj4 T elapses/:Wait until I-

On the other hand, the total d11 program (not shown) also enters a long line state, and as shown in the flyer of Figure 6, the direction T from time t□ to unit 11j is 1. , turn c/) The same figure at the wheel (a)
Accordingly, the output pulse is counted, and in the same way, the unit time T is 4 from 1:2 to 1:2, and the unit time T is 4.・Count blooming pulse P□. Same as Imugi(), time t
From n (n=3...n), the unit time 'r or 1 firing pulse PLτ count in 1 gun is counted.

Then, the time t when the unit time T passes through the axis from the time t□,
Then, the count dc'N of the detection pulse P□ is the set value A=
Is it 3 or more? ]l: Determine.

At this lJj point t, the count number CN from time t4 to c5 is 0N=I as shown in the figure, and the determination result is CN<A, so the determination is made again at time t6. At this point t6 and at point t □ Now, judge!
Since l'tn fruit fL also holds CN < A, next we re-discern υ/discrimination ``'rゐ at the point of contention t□.

At this time t, then, the unit time T from time t8 to t.
As shown in the figure, the count value CN of the 1 missing pulse P is reduced to CN = 3, and the discrimination result becomes CN≧A.
