Embodiment Construction
[0022] refer to figure 1 , a kind of urban rain and sewage pipe network misconnection and leakage rapid investigation system proposed by the present invention, comprising: a transmitting device, a plurality of receiving devices and a control module used in conjunction with the transmitting device;
[0023] The transmitting device is installed on the target manhole cover in the target area and is used to emit characteristic low-frequency sound waves into the manhole;
[0024] Each receiving device is respectively installed on other inspection shaft covers except the target inspection shaft cover in the target area, and is used to receive the characteristic low-frequency sound waves emitted by the transmitting device;
[0025] The control module acquires each characteristic low-frequency sound wave received by each receiving device, and determines whether there is a wrong or missing connection of the pipe network in the inspection shaft in the target area according to the low-fr...

The invention discloses an urban storm sewage pipe network misconnection and connection missing quick troubleshooting system and method. The system comprises an emitting device, a plurality of receiving devices matched with the emitting device for use and a control module. The emitting device is mounted on a target inspection well lid in a target area and used for emitting characteristic low-frequency sound waves to the interior of an inspection well. The receiving devices are mounted on the other inspection well lids except the target inspection well lid in the target area correspondingly andused for receiving the characteristic low-frequency sound waves emitted by the emitting device. The control module is used for acquiring all the characteristic low-frequency sound waves received by the corresponding receiving devices and determines whether misconnection or connection missing occurs to an inspection well internal pipe network in the target area or not according to the low-frequency sound wave characteristic spectra of all the characteristics low-frequency sound waves.
Description
technical field [0001] The invention relates to the technical field of drainage, in particular to a system and method for quickly checking wrong connections and missing connections of urban rainwater and sewage pipe networks. Background technique [0002] The inspection well is an underground space for the transfer and control of urban underground pipelines. In the city, all public water supply, sewage channels, telephone lines, and optical fiber networks may be connected through the underground passage under the inspection well. [0003] In the actual operation process, the types of inspection wells in a certain area are usually confused and unknown, and the maintenance and fault detection of the pipe network in the inspection well require the staff to open the inspection well cover and enter the sewer for operation, which is very inconvenient and The efficiency is low, and the inspection well ladder is often slippery, and it is easy for the staff to slip and fall when step...
