Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a kind of pig tracing system schematic that the embodiment of the invention provides.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Illustrative examples of the present invention and explanation thereof are used to explain the present invention; but it is not as a limitation of the invention; based on the embodiment among the present invention; those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of pig tracing system, as shown in Figure 1, Fig. 1 is a kind of pig tracing system schematic that the embodiment of the invention provides, rabbit 1 is a pipeline operations equipment, working environment is in pipeline, mainly be (also can be several support wheels by cylindrical skeleton and several leather cups, present embodiment describes with leather cup) the composition structure, form cylindrical cavity in the cylindrical skeleton, instrument can be installed, circuit etc., and leather cup is cylindrical skeleton can be supported in the pipeline, like this by advanced by fluid drives, because the structure of rabbit carrier 1 is a prior art, does not give unnecessary details so the present invention does not do too much at this.Rabbit 1 lift-launch machine 11 in the present embodiment, this transmitter 11 is used to launch the low frequency pulse signal of preset frequency.Such as 20～25 hertz low frequency pulse signal, certain preferably low frequency pulse signal of 23 hertz.This transmitter 11 comprises: with metal shell sealing and be installed in low-frequency pulse circuit 111 in rabbit 1 cylindrical skeleton, be used to produce the low frequency pulse signal of preset frequency.Emitting antenna 112 is used to launch the low frequency pulse signal of the preset frequency that low-frequency pulse circuit 111 produces, and emitting antenna 112 is mainly installed according to fluid flow direction, such as rabbit 1 foremost or rearmost end.Battery 113 is used for providing electric energy to described low-frequency pulse circuit 111 grades.Rabbit 1 is advanced in pipeline and just can be launched the low frequency pulse signal of preset frequency in the operation like this.The low frequency pulse signal of this preset frequency can penetrate duct wall and ground.
Receiver 2 can be installed on pipeline outer wall or the ground, and present embodiment is an example to be installed in ground.Along the duct orientation arrangement that keeps at a certain distance away, this receiver 2 comprises receiving antenna 21 to receiver 2, is used to receive the low frequency pulse signal of preset frequency on the ground.Because signal can be decayed when the low frequency pulse signal of the preset frequency of rabbit 1 emission in the pipeline penetrated pipe wall and surface process, so it is extremely faint that receiving antenna 21 receives the low frequency pulse signal of preset frequency, need this moment further the low frequency pulse signal of this preset frequency to be handled, therefore after receiving antenna 21 receives the low frequency pulse signal of preset frequency, in order to have reduced spuious electric wave, undesired signals such as pipeline are to the influence of low frequency pulse signal, amplification frequency selection circuit 22 in the receiver 2 can be used to improve the signal to noise ratio (S/N ratio) of the described low frequency pulse signal that receives, low-pass filter circuit 23 can be used for the low frequency pulse signal that has improved signal to noise ratio (S/N ratio) is carried out filtering simultaneously, thereby filtering goes out the low frequency pulse signal of preset frequency.Because the low frequency pulse signal that filtering goes out is a simulating signal, so the microprocessor 24 in the receiver 2 is used for filtered low frequency pulse signal is carried out analog to digital conversion, the low frequency pulse signal that filtering soon goes out is that analog signal conversion is the low-frequency pulse digital signal, and generates trigger pip according to digitized low frequency pulse signal.Because microprocessor 24 has obtained the low-frequency pulse digital signal, just mean that also receiver 2 determined to receive the low frequency pulse signal of the preset frequency of rabbit 1 emission, be that receiver 2 has traced into rabbit 1, so correlation tracking information will be sent to terminal unit, and this generation trigger pip promptly is the signal that the triggered location unit generates trace information.So the positioning unit 25 in the receiver 2 can be used for determining according to the trigger pip that microprocessor 24 sends the trace information of corresponding rabbit 1, and this trace information comprises the corresponding temporal information of described low frequency pulse signal and the geographical location information of described receiver of receiving.This positioning unit 25 is actual can be GPS (Global Positioning System) unit.This moment, microprocessor 24 was used for that also the correspondences that positioning unit 25 is determined are received the temporal information of described low frequency pulse signal and the geographical location information of described receiver is sent to communication unit 26.And the communication unit 26 in the receiver is used for that the correspondence that microprocessor 24 sends is received the temporal information of described low frequency pulse signal and the geographical location information of described receiver sends with communication.This communication unit 26 can be GSM (GlobalSystem for Mobile Communications, i.e. Global Link) unit.Receiver 2 has just been finished the task of reporting and submitting corresponding pig tracing information like this, promptly finished by the low frequency pulse signal that receives described preset frequency to determine it is rabbit, and correspondence has been received the task that the geographical location information of the temporal information of described low frequency pulse signal and described receiver sends with communication.
Need to prove, for effective electronic units such as sealing foregoing circuit, unit, present embodiment be with electronic part encapsulations such as foregoing circuit, unit in metal shell 27 inside, and power by battery 28.
Terminal unit in the present embodiment can be server 31 and/or portable terminal 32, is used to receive the temporal information and the geographical location information of the corresponding rabbit 1 that receiver 2 sends, so that server and/or mobile terminal tracing are to ducted rabbit 1.The user can be by the pig tracing information of server 31 storages like this, understand the detail location of rabbit operation in pipeline, also can know the detail location of rabbit operation in pipeline by portable terminal 32 immediately, greatly facilitate tracking, such as the tracking that better is applicable to mechanical tube cleaner or internal detector or pipe robot to rabbit.Judge that with traditional alarm sound, blinking light of listening the electronic cleaning-pipeline instrument receiver method of rabbit and transmitter site compares, the system that the embodiment of the invention provided requires also to reduce greatly to user's professional experiences, alleviate pigging operation and monitor personnel's working strength, reduce the pigging operation cost, the surface work personnel also can effectively avoid the influence of extraneous rugged surroundings to the person, have easily realized pig tracing.
Certainly; above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above is specific embodiments of the invention only, and is not intended to limit the scope of the invention, and is all within logic of the present invention and principle; any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
