Abstract
The present invention discloses a pipeline fluid monitoring method which comprises the following steps: 1) providing a plurality of net points on in a pipeline network of a fluid; 2) detecting the physical information of the fluid in a first net point, and converting the physical information into a sonar signal to send to a second net point; 3) receiving the sonar signal at the second net point, then converting the sonar signal into an electrical signal, converting the electrical signal and the fluid flow rate and pressure information detected at the second net point into a sonar signal to send to a third net point, and successively performing data collection and transmission; and 4) when the data is transmitted to n-th net point, sending the collected data to a system host. The pipeline fluid monitoring method uses sonar to transmit data to achieve wireless data transmission in the entire pipeline network, since the data transmission occurs in the pipeline, the influence of a variety of external environment can be avoided, stability is good, data fidelity is good, laying of communications cables at various net points is not needed, the cost is greatly reduced, construction is simple, time and labor are saved, and maintenance cost is greatly reduced.
Description
Technical field
The present invention relates to tap water pipe network technical field, refer to a kind of pipeline fluid monitoring method particularly.
Background technology
Existing tap water pipe network system is primarily of main frame, monitor and the communication cable and the service cable composition that connect each monitor and system host, the hydraulic pressure in running water pipe mainly monitored by monitor, and by cable, hydraulic pressure information and positional information are fed back to main frame, whether there are the abnormal conditions such as breakage, leakage in host analysis tap water pipe network.
Existing monitor is loop configuration, and its annular diameter is suitable with running water pipe.The mounting means of monitor is very complicated, needs first to be blocked by running water pipe, then the monitor of annular is arranged on incision position by ring flange, then lays to each monitor by the communication cable of system host and service cable by ground always, coupled.There is number of drawbacks in such structure, high, the main dependence on import of equipment manufacturing cost, difficulty of construction is large, maintenance cost is high and data acquisition and communication as easy as rolling off a log be subject to external condition restriction and interference.
Summary of the invention
The object of the invention is to overcome the mode adopting Data Over Cable in existing tap water pipe network system, the high and defect that data acquisition is easily limited of its cost, provides a kind of pipeline fluid monitoring method of wirelessly image data.
For achieving the above object, the pipeline fluid monitoring method designed by the present invention, its step is as follows:
1) multiple site is set on the piping network of fluid;
2) in the physical message of the first site place test fluid, and this physical message is converted to sonar signal and sends to the second site after data packing;
3) receive sonar signal at the second site place, the physical message being then converted to the fluid that electric signal and the second site place detect, after data packing, is converted to sonar signal in the lump and sends to the 3rd site, carry out Data Collection and transmission successively;
4) when data are delivered to the n-th site, all data collected are sent to information acquisition device;
5) all data received and the positional information of himself are packed by information acquisition device in the lump, send to system host.
Preferably, described physical message comprises at least one in flow velocity, pressure, temperature.
Preferably, described flow velocity is detected by ultrasonic transducer, and described pressure is detected by pressure transducer.
Preferably, described step 2) and 3) middle sonar signal sends and reception is received and dispatched by sonar sensor.
Preferably, described step 5) all data received and the positional information of himself pack by information acquisition device in the lump, are wirelessly sent to system host by GPRS.
Alternatively, the transmitting-receiving environment of described sonar signal is in pipeline.
Preferably, described step 2) and 3) in the data transmitted in sonar signal be source code data.
It should be noted that, the present invention not can be used only in tap water pipe network system, all applicable for multiple fluid pipe network.
Beneficial effect of the present invention:
1) by adopting sonar technique to utilize liquid to transmit data for medium, achieve the Wireless Data Transmission of whole piping network, because the transmission of these data occurs in pipeline, compare traditional cabled data transmission mode, the impact of multiple external environment can be avoided, good stability, data fidelity is good;
2), after adopting sonar transmission data, without the need to laying communication cable at each site place, cost is greatly reduced, construction is simple, time saving and energy saving, and compared to the maintenance of communication cable, maintenance cost of the present invention reduces greatly, and when safeguarding, workload is little, has saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of inventive pipeline fluid monitoring methods.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, pipeline fluid monitoring method, its step is as follows:
1) multiple site 10 is set on the piping network 40 of fluid;
2) at flow velocity and the pressure of the first site 10 place test fluid, and flow velocity and pressure information are converted to sonar signal after data packing send to the second site 10;
3) sonar signal is received at the second site 10 place, then the flow velocity of the fluid that electric signal and the second site 10 place detect and pressure information is converted to after data packing, be converted to sonar signal in the lump and send to the 3rd site 10, carry out Data Collection and transmission successively;
4) when data are delivered to the n-th site 10, all data collected are sent to information acquisition device 20;
5) all data received and the positional information of himself are packed by information acquisition device 20 in the lump, are wirelessly sent to system host 30 by GPRS information transmitter 50.
The transmitting-receiving environment of above-mentioned sonar signal is in pipeline.
Above-mentioned steps 2) and 3) in the flow velocity of fluid be detected by ultrasonic transducer (not shown), the pressure of fluid is detected by pressure transducer.
Above-mentioned steps 2) and 3) middle sonar signal sends and reception is received and dispatched by sonar sensor (not shown).
Above-mentioned steps 2) and 3) in the data transmitted in sonar signal be source code data.Because sonar signal transmits data in water, and sonar bandwidth is narrower, and to make it transmit data volume less, the source code data of recompile can be adopted to transmit, the source code data of coding are translated at system host 30 place, enable a small amount of data compile relatively large information, accelerate the gathering speed of information.
Above-mentioned site is in for arranging fluid monitor in practice of construction, and fluid monitor can adopt powered battery, then do not need to lay service cable to each site, and construction is simpler, and cost is lower.
