2. Description of the Related Art Leakage from water purification plants and distribution pipes and water pipes from distribution reservoirs to consumers reaches about 10% of the total amount of water distribution, which is enormous when converted to the total amount. Become. The development of new water sources to compensate for leaked water requires even more money. Therefore, it is an urgent task to promptly know the occurrence of water leakage and control the amount of water leakage.

As this type of water leakage detection device, there are a method using an audio device and a method using an attached automatic detector. The method using a sound hearing aid is that the investigator hears the vibration sound transmitted from the sound hearing aid by hitting the sound hearing aid on the ground where the water pipeline is buried or directly contacting the buried pipeline, and the water leaks. This is a method of determining the presence or absence.

However, in order to prevent erroneous detection due to noise other than water leakage in either method, it is necessary to perform work in the late-night zone where noise does not occur, which imposes a heavy burden on the operator. Also, detection with a hearing aid requires skill. On the other hand, in the case of an automatic detector, a high degree of skill is not required, but some technical knowledge is required. As described above, the use of the automatic detector has considerably reduced the labor required for the investigation as compared with the case where the hearing aid is used, but there is still room for improvement such as the investigation extending to midnight in some cases. In addition, in either method, a full-time researcher must visit the entire city area, which requires a huge amount of labor and time, so that there is a problem in that the location of the leak cannot be detected slowly.

FIG. 3 shows a detailed structure of each part shown in FIG. In FIG. 3, when the vibration generated in the water pipe 3 is detected by the acceleration sensor unit 16, a voltage corresponding to the level of the vibration is generated, and when the voltage exceeds a certain set value, the transistor Tr is turned on, and the condition operation unit It is output to 19. In addition, the meter stop detection unit 18 outputs a stop state detection signal of the electronic meter 1 to the condition operation unit 19. When the electronic meter 1 is stopped in the condition operating unit 19, that is, when there is no circulation of tap water, when the vibration signal from the acceleration sensor 16 is above a certain value, the power control unit 20 is used. Start the counter unit 21,
Vibration continuity is measured. When the vibration continues for a certain period of time or more in the state where the tap water is not flowing, it is determined that there is a water leak, and a water leak signal is output to the indicator 22 that can hold the display.

This state means the state of b in the time chart of FIG. 4 showing the operation timing of each signal.
That is, when the acceleration sensor 16 detects the vibration while the meter 1 is in the off state, the power of the counter section 21 is turned on at that point and the counting of the clock pulse generated from the oscillator of FIG. 3 is started. If this count continues for a certain period of time T or more, it is determined that there is water leakage, and it is displayed on the display unit.

On the other hand, even when the electronic meter 1 is stopped, the acceleration sensor 16 may operate due to artificial vibrations in the surroundings. In this case, the power of the counter unit 21 is temporarily turned on and starts counting, but artificial vibration or the like is not continuous. Therefore, when the vibration is interrupted, the power of the counter unit 21 is turned off and the count value is counted. To reset. These mean the state of a in FIG. Further, even if the vibration signal from the acceleration sensor 16 exceeds a certain value, if the electronic meter 1 operates and water is flowing through the water pipe, it is determined that this vibration is flowing water vibration, and the condition operation is performed. The counter section 21 is not operated by the off operation of the section 19. That is, when the acceleration sensor 16 detects vibration and the meter 1 is turned off, the power of the counter unit 21 is turned on, but in the case of artificial vibration or the like, there is no continuity and the count value reaches the fixed time T. Before that, the power of the counter unit 21 is turned off.

Since the water leakage detection device 2 is attached to the water meter 1, the presence or absence of water leakage can be confirmed on the display 22 when the meter 1 is subjected to meter reading. That is, since it is possible to know the presence or absence of water leakage at the time of meter reading, which is always performed on a regular basis, it is not necessary to perform a detection work by a special water leakage detection person.
Further, by activating the meter 1 only when the condition that the meter 1 is not used and the vibration is equal to or higher than the set level is met, it is possible to significantly reduce the power consumption for water leak detection. Therefore, for example, even if the built-in power supply battery is shared in the electronic meter 1, the power consumption does not become excessive,
The battery life can be maintained as before.
