Abstract
This utility model relates to a kind of monitoring system of sensor at each node of grid, this system includes being located at the monitoring sensor at each node of grid, and described monitoring sensor includes: hydrophone, demodulator, logical analysis circuit and the manipulator being sequentially connected with；Demodulator demodulation hydrophone receives the acoustical signal propagated in water pipe；Signal after the demodulation of logical analysis processing of circuit, if this acoustical signal is command signal, then controls to send back in water after manipulator is modulated.Execution instruction or modulates information, according to underwater sound communication principle, are become audio signal, utilize sound propagation in water pipe to reach each network node sensor and be monitored by this utility model, thus without relying on wired or wireless network again.
Description
Technical field
This utility model relates to the monitoring of grid, passes at each node of grid in particular to one
The monitoring system of sensor, valve state and instruction execution at node each to grid inside are carried out
Monitoring in real time.
Background technology
China's public supply mains leak rate reaches 15%～30% at present, and some places are even more than 50%.
Pipe leakage is also worldwide common problem, it is estimated that, in global range, pipe network leak rate is put down
Being 20%～30%, therefore the annual whole world lose more than 14,000,000,000 dollars.Therefore network of rivers pipeline is leaked
Regimen condition must carry out round-the-clock real-time monitoring.
Network of rivers pipeline monitoring method is typically to insert monitoring sensor, monitoring sensing at each network node
Device accepts instruction by wired or wireless method, performs instruction and to wired or wireless network-feedback shape
State information.Restriction yet with conditions such as geographical and operation costs is not to deposit at each pipe network
At wired or wireless network.Therefore, how in the environment of there is no wired or wireless network, it is achieved right
The detection of monitoring sensor becomes technical problem urgently to be resolved hurrily.
Summary of the invention
This utility model aims to overcome that above-mentioned the deficiencies in the prior art provide a kind of for grid
The monitoring system of sensor at each node, this utility model, according to underwater sound communication principle, will perform instruction
Or modulates information becomes audio signal, sound propagation in water pipe is utilized to reach each grid node
Sensor is monitored, thus without relying on wired or wireless network again.
Realize this utility model purpose and the technical scheme is that a kind of biography at each node of grid
The monitoring system of sensor, including the monitoring sensor being located at each node of grid, described monitoring senses
Device includes: hydrophone, demodulator, logical analysis circuit and the manipulator being sequentially connected with；Demodulator solution
Hydrophone is adjusted to receive the acoustical signal propagated in water pipe；Signal after the demodulation of logical analysis processing of circuit, as
This acoustical signal is command signal, then control to send back in water after manipulator is modulated.
In technique scheme, it is connected with in turn between described hydrophone and demodulator and puts for signal
Big preamplifier and the wave filter for filtering.
In technique scheme, between described logical analysis circuit and manipulator, it is also associated with switch.
In technique scheme, described manipulator outfan connects power amplifier, power amplification
Device connects underwater sound loudspeaker.
Execution instruction or modulates information, according to underwater sound communication principle, are become audio signal by this utility model,
Utilize sound propagation in water pipe to reach each network node sensor to be monitored, thus without
Rely on wired or wireless network again.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation of the monitoring system of sensor at each node of grid
Figure.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
This utility model is the monitoring system of sensor at each node of grid, including being located at grid
Monitoring sensor at each node.The structure of monitoring sensor is as it is shown in figure 1, include: be sequentially connected with
Hydrophone, preamplifier, wave filter, demodulator, logical analysis circuit, manipulator, power
Amplifier and underwater sound loudspeaker, be provided with switch between logical analysis circuit and manipulator.
The work process of this utility model system is as follows:
Water transmission acoustical signal through hydrophone receive after, successively through preamplifier amplify, filtering
Demodulator, the signal incoming logical analysis circuit after the demodulation of demodulated device is entered after device filtering.Logic is divided
This signal can be analyzed by analysis circuit, and as judged, it is switch to be made close after command signal, will solution
The signal adjusted is delivered in manipulator again, by the signal after modulating after power amplifier amplifies, by water
Signal is sent back in water by horn again, passes under continuing.
In this utility model, monitoring sensor can be made up of discrete component, it is possible to if be integrated into one or
Dry functional device.Demodulator used by the present embodiment and manipulator may also be decoder and encoder, and logic is divided
Analysis circuit also can be by chip microcontroller.
