Description

The hydrological telemetering device

One, technical field

The utility model relates to a kind of hydrological telemetering device.

Two, background technology

Along with the construction of present social water conservancy, large, medium and small reservoir or other water conservancy projectss are more and more, reservoir or other water conservancy projects facilities often aloft or closer from the people, if will lead to disaster to the supervision of this water conservancy is unfavorable.

Hydrology rainfall is a multidate information, and its size directly is concerned about the variation of next step water level, so can be indirectly provide information for the safety of water conservancy projects to a dynamic monitoring of rainfall.Hydrology rainfall is the important content of regimen information, is to use remote measurement, communication, computer and network technologies, finishes the basin or surveys the isolated plant of rainfall amount data acquisition, transmission and the processing of district's internal fixation and mobile site; Can be flood control and flood damage early warning decision support is provided.

Hydrology condensate tank of dehumidifier is the device that water level information is carried out real-time telemetry, transmission and processing, is the advanced means that effectively solves river basin and reservoir flood forecasting, flood control scheduling and water resources rational use.General water conservancy projects all has own ability to bear, and this ability to bear generally is to be weighed by water level, need be when approaching limiting water level to the water conservancy projects decompression that discharges water, otherwise can bring hidden danger to people's safety of life and property.

Three, summary of the invention

The utility model provides the hydrological telemetering device that can be used for monitoring the hydrology water level and the hydrology water yield of a kind of automatic collection, transmission rainfall information to above weak point.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of hydrological telemetering device, comprise central processing unit, be connected with clock circuit, display, storer, keyboard with central processing unit, comprise a rain sensor and liquid level sensor, described rainfall sensor is connected central processing unit with liquid level sensor through interface conversion circuit, is connected with wireless communication module with central processing unit.

Above-mentioned hydrological telemetering device, described rain sensor filter interface circuit through shaping and connect central processing unit.

Above-mentioned hydrological telemetering device, the encoded change-over circuit of described liquid level sensor connects central processing unit.

Above-mentioned hydrological telemetering device, described display connects central processing unit through photoelectric isolating circuit.

The utility model compared with prior art has the following advantages:

This device can be converted to electric signal with the switching value of level sensor, the information of liquid level sensor is encoded, water level and rainfall information are sent in the central processing unit, can monitor in real time the situation of water level and rainfall, simultaneously the situation of water level and rainfall can be sent to server, be convenient to knowing of people, for the action of implementing next step provides information.This device sensor adopts mechanical coding, does not need power supply.Can realize automatic measurement, data processing, data storage, data presentation inquiry and emission function in integrated function, simple in structure, easy to use, the reliability height, cost is low; Realize accurate, the collection automatically of water level information, and solved the contradiction between high precision and the low cost.After storehouse, river etc. are dry, need not manual synchronizing when coming water, reusable; And image data carried out long preservation, and can be widely used in fields such as rivers, lake, reservoir, water channel, hydroelectric power plant, have the advantages that adaptability is strong, purposes is wide.
