Description
Technical Field
The invention relates to a real-time pressure remote transmission system of an urban water supply network, in particular to a system for remotely transmitting real-time pressure monitoring of an external water supply network to a central control room monitoring platform.
Background
In the past, urban water supply enterprises have very weak strength in the aspect of pipe network pressure detection, and fixed pressure measurement points are few, and the manometer of installing is the mechanical table, needs artifical periodic observation record, often causes night pipe network inspection and pressure measurement to have the blank. Particularly, after the pipe is suddenly burst at night, the central control scheduling can only acquire factory pressure data of a water plant, the approximate range of the pipe burst cannot be judged, manual whole city general investigation is required for emergency use, early treatment cannot be found, and the leakage of a pipe network is reduced.
With the development of the internet of things technology, a cellular-based narrowband internet of things (NB-IOT) becomes an important branch of the Internet of things. The NB-IOT is constructed in the cellular network, only consumes about 180KHz bandwidth, and can be directly deployed in the GSM network, the UMTS network or the LTE network, so that the deployment cost is reduced, and smooth upgrading is realized. The NB-IOT focuses on the low-power-consumption wide-coverage networking market, is an emerging technology which can be widely applied in the global scope, has the characteristics of wide coverage, multiple connections, low speed, low cost, low power consumption, excellent architecture and the like, and is very suitable for data transmission such as pipe network pressure and the like.
At present, a plurality of remote transmission equipment development companies in the market generally mainly monitor flow, do not aim at special detection equipment of pipe network pressure, collect and store the flow in real time, and send data at regular time (4-10 times per day), for example, water leakage accidents such as sudden pipe bursting of the pipe network can not timely transmit the data to a monitoring platform.
Chinese patent document publication No. CN108007496, publication No. 2018, 5-8, discloses a self-powered remote system for simultaneously measuring temperature and pressure. The system comprises a measuring module, a data acquisition processing module, a data near-end communication module, a data remote transmission communication module, a power module, a server end and a checking terminal, wherein the measuring module is used for measuring parameters, the acquisition processing module is used for receiving data of the measuring module and transmitting the data to the server end through the data remote transmission communication module, and the checking terminal is used for acquiring the data of the measuring module through accessing the server end. The power supply module supplies power to each power utilization module in the system. The invention combines the temperature difference power generation system, the pressure measuring equipment, the temperature measuring equipment and the data remote transmission communication equipment together to form a remote transmission system which can be self-powered and can measure temperature and pressure. When the system is used for measuring the pressure of fluid, the measuring end of the integrated equipment is required to be inserted into the fluid to be measured, and the damping jackscrew in the accommodating cavity of the pressure measuring module is firstly jacked up by pressure impact generated by the fluid and then enters the accommodating cavity of the pressure measuring module to carry out pressure measurement. In order to prevent pressure leakage in the measuring process, before pressure measurement, after the pressure measuring module with the sealing ring is pressed into the accommodating cavity, the top end is tightly pressed by the fastening pressing nut in a threaded connection mode, the fastening pressing nut is coated with sealing glue by threads, and curable sealing glue is poured into the fastening pressing nut. The pressure measuring device is a stable value, and is used for determining the stability of pressure detection, and only damping jackscrews are used for reducing the impact pressure of water supply, so that the pressure measuring device is feasible in the heat supply and air conditioning fields, but the pressure detection is inaccurate due to the fact that the pressure fluctuation is particularly large in the urban water supply pipe network; in addition, in order to prevent pressure leakage, the integrated measuring device adopts more leakage prevention measures, so that the structure of the device is too complex, faults are easy to occur, and the device is not easy to maintain to a certain extent; in addition, after the differential pressure power generation system and the temperature difference power generation system are combined together, the differential pressure power generation system and the temperature difference power generation system can be used for generating power at the same time, but in an urban water supply network, the temperature difference of fluid is very small, the temperature difference power generation system almost does not play any role, and after the differential pressure power generation system and the temperature difference power generation system are combined together, the power generation system becomes complex, the failure rate is increased, the fluid channel of the power generation system is narrowed under the limited volume, the resistance is increased, the pipeline is easy to block, the power generation efficiency is greatly reduced, and the operation of the self-powered system is affected in severe cases.
