Abstract
Disclosed is a city underground pipeline construction detection device based on the electromagnetic induction technology. The city underground pipeline construction detection device based on the electromagnetic induction technology comprises an electromagnetic wave transmitting module, an electromagnetic wave receiving module, an electromagnetic wave analysis module and a warning module, wherein the data output end of the electromagnetic wave transmitting module is connected with the data input end of the electromagnetic wave analysis module, the data output end of the electromagnetic wave receiving module is connected with the data input end of the electromagnetic wave analysis module, and the data output end of the electromagnetic wave analysis module is connected with the data input end of the warning module. Transmitted and received electromagnetic waves are analyzed to judge whether metal obstacles exist in front of an excavator or not, and an early warning is given out in time if the metal obstacles exist so that the excavator can avoid an embedded pipeline.
Description
Technical field
The present invention relates to art of electronics, particularly relate to a kind of urban pavement underground pipelines construction sniffer based on electromagnetic induction technology.
Background technology
In Process of Urban Development, often there are a lot of pipelines under road, to pass, for these underground utilities are installed, need to bury at mine working.Pre-buried pipeline before easily running into when this work is carried out, causes a lot of unnecessary accidents, and it is wide that this class accident often has impact, the feature of maintenance difficult.At present, in excavation, bury in process, normally by the layout of people or the pre-buried pipeline of Computer Analysis, then plan and excavate circuit, but this process labor intensive, efficiency is lower, and lacks real-time analytical capability, can not to excavating the pipeline in the place ahead, carry out anticipation in time.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind ofly based on the automatic identification front of digging machine of having of electromagnetic wave transmitter, electromagnetic wave receiver, electromagnetic wave analysis processor and alarm installation composition, whether have preheating embedding line, thereby to driver, send the urban pavement underground pipelines construction sniffer based on electromagnetic induction technology of cue.
The technical solution adopted in the present invention is: the urban pavement underground pipelines construction sniffer based on electromagnetic induction technology, comprise electromagnetic wave transmitter module, electromagnetic wave receiver module, electromagnetic wave analysis module and alarm module, the data output end of electromagnetic wave transmitter module connects the data input pin of electromagnetic wave analysis module, the data output end of electromagnetic wave receiver module connects the data input pin of electromagnetic wave analysis module, and the data output end of electromagnetic wave analysis module connects the data input pin of alarm module.
Further, excavator, in the process of advancing, is constantly launched powerful electromagnetic wave by electromagnetic wave transmitter to dead ahead, to survey the place ahead, whether have metal hamper.
Further, if front of digging machine has pre-buried pipeline, reflection of electromagnetic wave is gone back, by electromagnetic wave receiver, received, signal feedback, to electromagnetic wave analysis processor, is compared this signal and presupposed information, to judge whether this metal is preheating embedding line, thereby select whether to driver, make prompting.
The present invention has advantages of:
1. there is real-time analytical capability.
2. device is convenient to install.
3. save the time of excavating preliminary analysis operation.
Accompanying drawing explanation
Fig. 1 is block diagram of the present invention.
Fig. 2 is configuration schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention is based on the urban pavement underground pipelines construction sniffer of electromagnetic induction technology, utilize electromagnetic wave transmitter to excavator dead ahead emitting electromagnetic wave, if there is metal hamper in the place ahead, electromagnetic wave is reflected back toward receiver, the electromagnetic wave that the docking of electromagnetic wave analysis processor is regained is analysed and compared, judge whether this metal hamper is preheating embedding line, if timely transmission of signal is to alarm reminder, to driver, send prompting, thereby avoid running into pipeline, cause unnecessary accident.
As shown in Figure 2, described electromagnetic wave transmitter module 2 is arranged on excavator dead ahead, refer to a kind of transmitter that comprises high frequency oscillator and emitting antenna, by high frequency oscillator, produce higher-order of oscillation electric current, be transported to after emitting antenna, in electromagnetic mode, launch, thereby survey the place ahead, whether have metal hamper.
Described electromagnetic wave receiver module 3 is arranged on excavator dead ahead, refer to a kind of receiving trap being formed by receiving antenna and wave detector, the electromagnetic wave being reflected by metal hamper is by antenna reception, form oscillating current, after the screening of wave detector, can obtain having the current information of metallic reflection characteristic.
Described preheating embedding line 4, refers in Process of Urban Development before, has buried the pipeline that is loaded on below, road surface.
Described electromagnetic wave analysis module 5 is arranged in engine bin safety box, refer to the frequency of received current signal is analyzed, compare with the power frequency that default pipeline reflection electromagnetic wave changes into, to judge whether this metal hamper is preheating embedding line 4, thereby select whether alarm module 6 to be carried to cue.
Described alarm module 6, refers to a kind of device that can send a warning to driver in time, when it receives after the cue that electromagnetic wave analysis module 5 transports, sends immediately alarm sound, and there is preheating embedding line in prompting driver the place ahead, should note the excavation of detouring.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
