Real-time pressure teletransmission system for urban water supply pipe network

Abstract

The invention discloses a real-time pressure teletransmission for an urban water supply pipe network. The system comprises a pressure sensor, a pressure signal teletransmission device, a pipe bypass power generating system, an IOT base station and an IOT monitoring platform. The pressure signal teletransmission device is connected with the pressure sensor and is used for teletransmitting the signal of the pressure sensor to the IOT base station through NB-IOT technology. The IOT base station forwards a data signal transmitted from the NB-IOT to the IOT monitoring platform. Through the IOT monitoring platform, recording of data transmitted from the NB-IOT, historical data processing and alarming are finished. The pipe bypass power generating system is connected with the pressure signal teletransmission device and is used for supplying electric power to the pressure signal teletransmission device. The system can realize teletransmitting the pressure condition of the pipe network to the IOT monitoring platform in real time. Once a water leakage accident such as pipe network explosion occurs, alarming can be performed in time, and an approximate pipe explosion position is displayed. The exploded pipe network can be treated in time, thereby reducing leakage loss of the pipe network.

Description

technical field [0001] The invention relates to a real-time pressure remote transmission system of an urban water supply pipe network, in particular to a system for remote transmission of real-time pressure monitoring of an external water supply pipe network to a central control room monitoring platform. Background technique [0002] For a long time, urban water supply enterprises have been very weak in pipe network pressure detection, with few fixed pressure measurement points, and the installed pressure gauges are all mechanical gauges, which require manual observation and records on a regular basis, often resulting in gaps in nighttime pipe network inspection and pressure measurement. Especially after the pipe burst suddenly at night, the central control dispatching can only collect the pressure data of the water plant factory, and cannot judge the approximate range of the burst pipe. It is necessary to use manual city-wide general surveys urgently, so that early detection...

Problems solved by technology

This invention can be better applied in the field of heating and air conditioning, but after it is applied to the urban water supply network, since the water consumption in the urban water supply network will have peaks and valleys according to the amount of water consumed by residents, The pressure fluctuates continuously within a certain range, which is not a stable value. In order to ensure the stability of pressure detection, the pressure measuring device in this invention only uses the up and down movement of the damping jack wire to reduce the impact pressure of the water supply. It is feasible in the field of heating and air conditioning, but in the urban water supply network, the pressure fluctuation will be particularly large, making the pressure detection inaccurate; in addition, the integrated measurement device has adopted more anti-leakage measures in order to prevent pressure leakage , to a certain extent, the structure of the device is too complicated, prone to failure, and difficult to maintain; in addition, after the invention combines the pressure difference power generation system and the temperature difference power generation system, although the pressure difference power generation system and the temperature difference power generation system can be used at the same time To generate electricity, but in the urban water supply network, the temperature difference of the fluid is very small, and the thermoelectric power generation system can hardly play any role. On the contrary, when they are combined, the power generation system becomes complicated and the failure rate will increase. Under the smaller volume, the fluid channel of the power generation system will also be narrowed, the resistance will become larger, the pipeline will be easily blocked, and the power generation efficiency will be greatly reduced. In severe cases, the operation of the self-power supply system will be affected.
