Description
Technical field
The utility model belongs to technical field of information communication, more particularly to a kind of Real Time Hydrologic based on power carrier communication
Information collecting device.
Background technology
At present, in hydraulic engineering, emphasis hydraulic structure periphery generally require installation rainfall gauge, water-level gauge, flowmeter,
The sensors such as atmidometer.To make these normal operation of sensor, it usually needs the corresponding power supply of laying and communication cable, due to wanting
Consider the factor such as anti-tampering of the communications cable, power supply is frequently necessary to be in charge of with the communications cable（Cable protection pipe）Laying, causes to pacify
Dress is complicated, cable is practical more, and construction cost is high.The sensors such as rainfall gauge, water-level gauge, flowmeter need regular scene to be checked
Debugging circuit is calibrated, it is necessary to remove original communication line and overlap temporarily with calibration, dismounting and connection repeatedly, so
Not only add workload but also unnecessary abrasion can be carried out to the wire connection terminal and cable tie of work, and in turn result in sensor operation
The reduction of performance.
In conclusion problem existing in the prior art is：Power supply is frequently necessary to be in charge of with the communications cable（Cable protection pipe）
Laying, causes installation complexity, cable practical more, construction cost is high.The sensors such as rainfall gauge, water-level gauge, flowmeter need regular
Scene check with calibration, it is necessary to which removing original communication line overlaps calibration debugging circuit, tearing open repeatedly temporarily
Unload and connect, so not only added workload but also unnecessary abrasion can be carried out to the wire connection terminal and cable tie of work, and then
Cause the reduction of sensor runnability.
The content of the invention
In view of the problems of the existing technology, the utility model provides a kind of Real Time Hydrologic based on power carrier communication
Information collecting device.
The utility model is realized in this way Real Time Hydrologic Information harvester setting that should be based on power carrier communication
Have：
Detect the sensor of data message；
It is electrically connected with sensor, is used for realization the power carrier communication modem of gathered data modulation /demodulation；
It is electrically connected with power carrier communication modem, is used for realization the communication host computer of data communication；
It is electrically connected with power carrier communication modem, is used for realization the power supply of supply of electric power；
It is electrically connected with power carrier communication modem, is used for realization check and the calibrating installation of information inspection.
Further, the power carrier communication modem is equipped with some pins and connects the wire connection terminal of power supply.
Further, the power carrier communication modem is realized by eight screws and is mechanically fixed and installs.
The advantages of the utility model and good effect are：
1st, power supply and communication are shared into a cable, i.e., carries out signal communication, cable with power carrier on service cable
Installation is simple and can effectively reduce pipeline construction cost more than 35%.
When the 2nd, working normally, communicated using the compound port of powered communication, when needing check with calibration,
Enable spare communication terminal and carry out provisional communication connection, the compound port of powered communication only has equipment function of supplying power at this time, treats
Check and be connected with removing provisional communication after the completion of calibration, the compound port of powered communication restores electricity and the work(that communicates again at this time
Energy.Workload was so not only reduced but also the abrasion of the wire connection terminal and cable of work can be reduced, Mean can be extended
Time（MTBF）3000 it is small when more than.

Embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Attached drawing describes in detail as follows.
The structure of the utility model is explained in detail below in conjunction with the accompanying drawings.
The Real Time Hydrologic Information harvester based on power carrier communication is provided with：
Detect the sensor 2 of data message；
It is electrically connected with sensor 2, is used for realization the power carrier communication modem 1 of gathered data modulation /demodulation；
It is electrically connected with power carrier communication modem 1, is used for realization the communication host computer 3 of data communication；
It is electrically connected with power carrier communication modem 1, is used for realization the power supply 4 of supply of electric power；
It is electrically connected with power carrier communication modem 1, is used for realization check and the calibrating installation 5 of information inspection.
As the preferred embodiment of the utility model, the power carrier communication modem 1 be equipped with some pins and
Connect the wire connection terminal of power supply.
As the preferred embodiment of the utility model, the power carrier communication modem 1 passes through eight screw realities
Now it is mechanically fixed and installs.
The operation principle of the utility model：
A kind of specific communication mode of information transmitting medium data transfer is used as by the use of 220V low-voltage distribution wires.Should be based on electricity
The power carrier modem that the Real Time Hydrologic Information harvester of power carrier communication is selected can realize RS485 interfaces and electricity
The switching of power carrier wave（This programme selects PLM39 power carrier communications modem 1）, 2 delivery outlet of sensor also uses RS485
Interface modes.
The effect of power carrier interface is the connection established between carrier circuit and external communication medium, under normal circumstances,
What carrier media was connected together with power supply 4.When sensor 2 works normally, power supply 4 only need to be connected, carrier wave is just
It can be communicated by power cord, the 3-4 feet of PortA link together in the internal 1-2 feet with PortA at this time, to outside
For, 3-4 feet do not connect vacantly.
The water level, the high-frequency signal of the information such as flow that are loaded with are loaded on electric current by the utility model, then utilize 220V etc.
The power line transmission of level, the modem for receiving information is separated high-frequency signal from electric current again, and is transmitted to information
Gather host computer.
When sensor 2 check with calibration, carrier wave is separate with power supply, at this time the 1-2 connection works of PortA
Make power supply, the 3-4 feet of PortA are connected with exterior provisional communication medium, they are mutually independent, and inside is short-circuit even without progress
Connect.
Wait to check and be connected with removing provisional communication after the completion of calibration, the compound port of powered communication restores electricity again at this time
With communication function.The 3-4 feet of PortA recover to link together again in the internal 1-2 feet with PortA.
The above is only the preferred embodiment to the utility model, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model to any simple modification made for any of the above embodiments, equivalent variations with
