DETAILED DESCRIPTION OF THE INVENTION

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water end data measuring device for measuring pressure and water quality at the end of a water supply branch.

[0003]

2. Description of the Related Art The pressure and water quality at the end of a water supply pipe can be realized by a conventional technique using a sensor and a telemeter device, but it is necessary to install a number of expensive telemeter devices in the city in order to spread it to all water supply houses. There is.

[0004] Recently, an electronic water meter with a built-in microcomputer having a function of intensively and automatically measuring the amount of water used by a water meter has been developed. There was no utility value for the customer.

[0005]

The water service bureau, whose mission is to provide a stable supply of water to consumers, has a problem of poor water output at the end of the water supply pipe.
Residual chlorine concentration, pressure to monitor red water generation, residual salt,
A device for easily measuring chromaticity has been desired. However, even if the data of all the water supply houses is constantly collected, there is a problem that the amount of data becomes enormous, and the telemeter facility cost and the communication cost increase, which is not practical.

[0006] In addition, consumers report complaints such as poor flooding and red water generation to the Waterworks Bureau by telephone.
The chromaticity and other numerical values could not be shown, making it difficult for the Water Bureau to respond.

[0007] The present invention provides a means for easily notifying when a customer detects an abnormality in water supply, and a water end data measuring device capable of adding pressure and water quality data near a water meter when an abnormality occurs and transmitting the data to a waterworks station. The purpose is to provide.

[Structure of the Invention]

[0009]

SUMMARY OF THE INVENTION The present invention provides a water meter for automatic meter reading, a pressure gauge for measuring the pressure of tap water in a water pipe connected to the water meter, and a concentration of chlorine remaining in the tap water. , A chromaticity meter for measuring the chromaticity of tap water, and an output signal of the chromaticity meter, pressure gauge, and the residual chlorine concentration meter, and an input signal from a customer terminal device. A water end data measuring device comprising a signal synthesizing circuit and a signal adding circuit for adding an output signal of the signal synthesizing circuit to an output signal of a water meter.

[0010]

In the tap water end data measuring device of the present invention, the pressure and water quality sensors output an electric signal unified with instrumentation of the pressure and water quality of tap water, and the customer terminal presses a button indicating the content of the complaint. The microcontroller built in the water meter reads the contact signal output from the customer terminal and reads the value of the sensor at that time in addition to transmitting the meter reading to the center. The type of signal (contents of the complaint) and the value of the sensor are transmitted together to the center, and the reading of the sensor value is also performed upon request from the center.

[0011]

Next, an embodiment of the present invention will be described. FIG. 1 shows a water meter 4 for automatic meter reading, a pressure gauge 1 for measuring the pressure of tap water in a water pipe connected to the water meter 4, and a residual chlorine concentration meter for measuring the concentration of chlorine remaining in the tap water. 2
A chromaticity meter 3 for measuring the chromaticity of tap water, a signal synthesizing circuit 5a for synthesizing output signals of the chromaticity meter 3, the pressure gauge 1, the residual chlorine concentration meter 2, and an input signal from the customer terminal device 6.
A signal adding circuit 5b for adding an output signal of the signal synthesizing circuit 5a to an output signal of the water meter 4, a water meter 4 having a built-in microcomputer, which is a water terminal data measuring device provided with the automatic meter reading, A water supply system that consists of a sensor that measures the pressure and water quality near the meter in the water pipe and a terminal that allows the customer to input abnormal information on water supply, and that when water supply is abnormal, the data at that time can be added and transmitted to the Waterworks Bureau. It is a terminal data measuring device.

That is, a pressure gauge 1 for measuring pressure near a water meter, a residual chlorine concentration meter 2 for measuring water quality, and a chromaticity meter 3
And a microcomputer 5 built in the water meter 4 and a water terminal data measuring device comprising a customer terminal device 6 connected to the microcomputer 5 for the customer to input a complaint content. And transmits information to the center of the waterworks bureau via a public communication line. It should be noted that a sensor may be added or deleted as required in addition to the sensor shown in FIG.

FIG. 2 is an example of an external view of the customer terminal device 6. Push button switches 9 and 8 on which complaints such as good water, abnormal odor, red water, and water outage are printed are attached.

FIG. 3 is an example of a circuit of the customer terminal 6,
Reference numeral 31 denotes water cutoff, reference numeral 32 denotes red water, reference numeral 33 denotes an abnormal odor, and reference numeral 34 denotes a contact which operates due to poor water discharge.

FIG. 4 shows a functional flowchart of a microcomputer built in the water meter. This program operates at predetermined execution cycles.
Reference numerals 9, 0, and 11 denote processes for automatic meter reading;
Processes 3 and 14 are processes for reading a sensor signal and a complaint signal when a customer complaint is input and transmitting the signal to the Waterworks Bureau. Processes 15, 16, and 17 are processes for reading and transmitting sensor signals upon request from the waterworks bureau.

[0016]

According to the present invention, water pressure and water quality data at the end of a water pipe can be easily and collectively used in a transmission route of an automatic meter reading, and when an abnormality occurs, a customer can notify the water service bureau of the abnormality through the above route. At the same time, since the data at that time is added, the water service bureau can easily handle and analyze the data, and the customer can also be notified promptly.
