Description

Underground heat well head data acquisition and monitoring device

Technical field

The utility model belongs to the geothermal heating technical field, particularly relates to a kind of underground heat well head data acquisition and monitoring device.

Background technology

In recent years, along with China's rapid development of economy, the improving constantly of living standards of the people, heating installation has entered into huge numbers of families; And underground heat is as a kind of clean energy resource, more and more be subject to liking of the people in field of heating, but, as everyone knows, the temperature of underground heat well head is higher, and air pressure is larger, for the harmony that guarantees heat supply and the stationarity of temperature, people generally all arrange a plurality of sensors in the porch of geothermal heat pipeline, gather the temperature of underground heat well head such as the set temperature sensor; The pressure that pressure transducer gathers the underground heat well head is set; The gas flow that flow sensor gathers the underground heat well head is set; Also at the underground heat well head rig camera being set simultaneously is used for the field conditions of geothermal well mouth is carried out Real-Time Monitoring, the data communication device that afterwards the sensor and rig camera is collected is crossed data line and is transferred to Programmable Logic Controller, and by on-the-spot man-machine interface demonstration, or on the computing machine of underground heat well head next door Control Room; But, find through long-term practice, because underground heat well head major part is in residential district or Office Area away from the mankind, therefore in order to guarantee the safety of underground heat well head, the staff must stand fast at the Control Room at the underground heat well head constantly, simultaneously, when geothermal well mouth abnormal situation, the monitor staff who is responsible for monitoring need to be with information reporting to the master-control room staff, then the master control staff analyzes judgement to abnormal conditions, and then handle it, but when a plurality of underground heat well heads simultaneously during the abnormal situation, the Control Room staff on a plurality of underground heat well heads next door reports to master-control room simultaneously, to cause the communication of master-control room will occur stopping up, the artificial error that makes mistakes of reporting will also often occur simultaneously.

Summary of the invention

In sum, goal of the invention of the present utility model is: a kind of underground heat well head data acquisition and monitoring device is disclosed, make its have the data remote function, simultaneously have economize on resources, characteristics that transfer efficiency is high.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

A kind of underground heat well head data acquisition and monitoring device comprises: sensor unit, Programmable Logic Controller, rig camera and with the computing machine of described monitoring camera mechatronics; The analog output port of described sensor unit is electrically connected with the analog input port of described Programmable Logic Controller; It is characterized in that: also comprise GPRS teletransmission unit, INTERNET Internet Transmission unit, switch and main control unit; Wherein:

The RS485 communication interface of described GPRS teletransmission unit is connected with the RS485 communication interface of described Programmable Logic Controller by the PROFIBUS data line; Be equipped with the transport module that is used for to each other the information wireless transmission on described GPRS teletransmission unit and the described INTERNET Internet Transmission unit; Connect successively by optical fiber between described INTERNET Internet Transmission unit, described switch, the described main control unit.

Further: described sensor unit comprises: temperature sensor, pressure transducer and flow sensor;

Described computing machine is connected with described INTERNET Internet Transmission unit by modulator-demodular unit;

Described main control unit is main control computer;

Advantage and the good effect that the utlity model has are: the utility model is by adopting technique scheme, realized the remote transmission of the data acquisition of underground heat well head and work condition inspection, the monitoring when staff can realize a plurality of well head by a master-control room, greatly saved resource, improve simultaneously the efficient of work, avoided the defective that makes a mistake.
