The present invention relates to a real-time monitoring mobile sewage pipe flow meter, and more particularly, a sensor unit provided in the sewage pipe measuring the flow rate of the sewage pipe, a logger unit for transmitting data received from the sensor unit to the outside, the sensor unit and Formed between the logger unit and configured to transmit and receive data measured by the sensor unit to the logger, by adjusting the flow measurement interval over the Internet to adjust the battery consumption time, and wirelessly transmit and receive flow data without going to the field In addition, it is possible to conveniently write a report and at the same time prevent the theft of the flow meter.In the event of sudden heavy rain drainage, it is possible to send texts to up to 8 or more smartphones registered in advance at the same time, or to send Google, Naver, Real-time mode to display alarms on the map The present invention relates to a kneading mobile sewer flow meter.

Sewerage is an important infrastructure that is essential for the protection of people's environmental rights. However, unlike the sewage pipeline system centered on sewage treatment, domestic sewage facilities have been focused on sewage treatment facilities and sewage treatment rates that have been mainly categorized since the mid-1980s in a confluence system based on the sewage exclusion system with excellent drainage. Due to the lack of awareness of sewage pipelines, the maintenance of sewage pipelines was neglected and I / I (infiltration / inflow) increased, which contributed to the increase of load and inefficiency of sewage treatment facilities.

Inflow / inflow water (I / I) increases the flow rate, lowers the water supply capacity, and even overflows out of the manhole (SSOs) to create a flooded area, and lowers the sewage concentration of the sewage treatment facility. It adversely affects the facility efficiency. On the other hand, water leakage is a phenomenon that the sewage leaks from the poor portion of the pipeline when the groundwater level is lower than the sewage pipe causes a contamination of the groundwater of the surrounding soil.

In addition, in the sewage pipeline system, the dual structure of manure treatment and I / I due to the structural problems of the sewage pipe have led to many problems such as maintenance of the sewage pipe. Therefore, it is essential to investigate the infiltration / inflow of the sewage pipes in order to accurately identify these problems and prepare appropriate countermeasures.

As such, for the conventional I / I analysis, as shown in FIG. 1, a flow meter is installed at each required position of the sewer pipe to measure the flow rate and to store and analyze the data so that the sewage pipe in the sewage pipe may be connected to the ground, causing damage, deterioration, etc. Find out the amount of infiltration and leakage caused. Electronic, ultrasonic, and flowmeters meet most of the above mentioned conditions and have advantages in usability, economics, and precision, and are used for flow measurement by installing them in sewer pipes.

In addition, the battery of the flowmeter usually uses 12V-12AH of industrial weight and weighs about 3.6kg. The flowmeter's sensor is fully waterproof with IP-68, and the flowmeter's logger is waterproof with IP-67, and it can withstand 3 hours when fully filled in sewer pipes. In many cases, sewage intrusion causes loss of data that has been measured, as well as logger failures that require disposal or expensive repairs. Most sewer line flowmeter loggers are not designed to be mounted inside sewer lines, but are mostly developed overseas to read data by fixedly installing them on the ground.

On the other hand, the domestic reality is the method of moving and measuring each sewage point to regional sewer pipes in order to measure I / I. Therefore, in order to prevent theft and to ensure the safety of citizens, the manhole cover must be closed after installing a flowmeter sensor and logger inside the sewer pipe. do. Therefore, when the manhole is filled with sewage pipes during the rainy season, it is common to see the flowmeter logger flooded.

In addition, in order to know whether the intermediate intermediate flow meter works well and the data is being measured well, it is cumbersome to go to the site and open the manhole cover and download the data by connecting the flowmeter logger and the notebook. Some citizens have been approached and stolen with malice.
