Detailed description of the invention
Detailed description of the invention one: see figures.1.and.2 and illustrate present embodiment, ultrasonic water meter pipeline leakage described in present embodiment and booster detection method, the method is that ultrasonic water meter realizes, and this ultrasonic water meter includes: ultrasound wave base table 1 and ultrasonic transducer 2;
Having two openings on the sidewall of ultrasound wave base table 1, two ultrasound wave correlation ends of ultrasonic transducer 2 are each passed through two openings and are positioned at ultrasound wave base table 1 inside, and are sealed by place opening, and two ultrasound wave correlation ends of ultrasonic transducer 2 are facing each other,
Described ultrasonic water meter pipeline leakage and booster detection method comprise the following steps:
Step one: judge whether ultrasonic water meter can collect signal, is perform step 2, otherwise carries out sensor fault/blank pipe and reports to the police, then performs step 5;
Step 2: judge whether ultrasonic water meter is reversely installed, otherwise performs step 3, is, reversely install warning, then perform step 5;
Step 3: judge whether water pipe bursts, otherwise performs step 4, is, carry out booster warning, then perform step 5;
Step 4: judge whether water pipe leaks, otherwise performs step 5, is, carry out leakage alarm, then perform step 5;
Step 5: report the above-mentioned alarm signal occurred in steps to the main control end of Running-water Company, completes detection.
In step 5, if step one occurs in that warning to step 4, then report the above-mentioned alarm signal occurred in steps to the main control end of Running-water Company, if water pipe is normal, does not occur reporting to the police, then complete one-time detection process.
The data of water meter collection are progressively compared, and then progressively judge whether water pipe breaks down by ultrasonic water meter pipeline leakage described in present embodiment and booster detection method, and then reliably, effectively water pipe state is detected.
Detailed description of the invention two: present embodiment is that the ultrasonic water meter pipeline leakage described in detailed description of the invention one and booster detection method are described further, in present embodiment, performs following steps after step 5:
