Summary of the invention
Be the deficiency of the existence that solves prior art, accurately and rapidly judge the position of booster point in the tap water pipe network, improve locating accuracy, and realization is managed effectively to the related data of pipe network operation situation.
The utility model provides a kind of tap water booster monitoring system, it is by an automatic monitoring center, a plurality of mains road monitoring station and a plurality of bye-pass monitoring station are formed, be used for operational outfit to each water factory's remote scene and monitor and control, transmit and the automatic control of valve switch with the data that realize the monitoring of tap water supply ductwork pressure, discharge.
Described automatic monitoring center comprises an Industrial Personal Computer (IPC), and described Industrial Personal Computer (IPC) is inner installs memory, and links to each other with the wireless data receiving system.
Described dried, bye-pass monitoring station links to each other with automatic monitoring center by the wireless data transmission manner, and hydraulic pressure information and flow transmitter are measured, gathered to each website setting pressure sensor, measures, gathers flow information.

The specific embodiment
A kind of tap water booster monitoring system, comprise automatic monitoring center and several Heavenly Stems and Earthly Branches pipeline monitoring stations, each website is installed flow and pressure sensor, adopt the GPRS wireless transport module to carry out the transmission of data, pressure with monitoring station, data on flows is sent to the Industrial Personal Computer (IPC) of appointment by China Mobile's wireless network, and be presented in the monitoring interface, the operator just can grasp the real-time pressure data of the monitoring station that is distributed in various places by monitoring interface, when pressure has surpassed the warning restriction that arranges, monitoring system can in time be sent the warning message notification operator, and is quicker, find class location of fault and degree such as water supply pipe booster accurately.
Adopt tap water booster monitoring system, this system comprises an automatic monitoring center, sets gradually a plurality of main way station point, a plurality of bye-pass websites, and each website is installed flow transmitter and pressure sensor, is used for gathering and feedback flow and pressure signal.Feedack is analyzed; can effectively protect action: when the flow of gathering when some websites and pressure signal are undesired; then the booster fault appears in this section, and system closes the nearest valve in this section pipeline front automatically, and points out by sound and light alarm.
Several Heavenly Stems and Earthly Branches pipeline websites are equipped with: pressure sensor, be installed on the monitoring station water supply network, and link to each other with the GPRS wireless transport module, for detection of the pipeline pressure signal of this website, and be converted to 4~20mA current signal feedback.Flow transmitter is installed on the monitoring station water supply network, links to each other with the GPRS wireless transport module, for detection of the pipeline flow signal of this website, and is converted to 4~20mA current signal feedback.The GPRS wireless transport module links to each other with website sensor and automatic monitoring center Industrial Personal Computer (IPC), is used for the transmission detected flow of each website and pressure signal.
Monitor procedure may further comprise the steps:
1, starts Industrial Personal Computer (IPC), tap water booster monitoring system and storage are set;
2, input pipe network basic data and storage;
3, Surveillance center instructs the pressure sensor of each Heavenly Stems and Earthly Branches pipeline website, flow transmitter to carry out hydraulic pressure and flow monitoring automatically;
4, measurement, collection and the feedback of hydraulic pressure and flow carried out in the instruction of sensor follow procedure, and survey data is converted into 4~20mA current signal, is sent to Industrial Personal Computer (IPC) by the GPRS data transmission module;
5, automatically Surveillance center's image data that sensor is passed back is analyzed, and makes water supply network and whether has the booster fault, and carry out the booster failure location and fault degree is judged.
Compared with prior art, advantage of the present utility model and good effect are:
1, automaticity height has been realized the unmanned booster of monitoring automatically situation;
2, adopt the GPRS data transmission module, utilize mobile communication network to carry out transfer of data, more safe and reliable;
3, each website apart from 1km about, can pick out accident point more accurately;
Instantaneous pressure and the flow that 4, can show each website place pipe network by monitoring system; can set in advance the upper pressure limit of bearing of pipe network; when the signal that feeds back arrived upper pressure limit, minimizing equipment operation quantity was in order to reach the purpose of protection pipe network automatically.
5, analyze by monitoring center's feedack, can effectively protect action, after detecting a certain section pipeline booster, system closes the nearest valve in this section pipeline front automatically.
System with regard to six monitoring stations is example, as shown in drawings, automatic inspection center is arranged in the water supply control room, water works, outside water factory, begin to arrange website behind the certain distance, there are three to be main road monitoring station in six websites, other three is the bye-pass monitoring station, is distributed as between the monitoring station of main road apart from being 1km.When system moves, each monitoring station is passed the flow of each monitoring station and pressure signal back automatic monitoring center by the GPRS data transmission module, can see flow and the pressure of each monitoring station by configuration picture, the signal that the automatic comparative analysis of system receives, if irregular variation appears in the signal of which monitoring station, then system closes the nearest valve in this section pipeline front automatically, and the concurrent alert signal of delivering newspaper shows that this section pipeline breaks down, and has the possibility of booster.
