Description
Technical field
The embodiment of the present invention is related to location technology, and in particular, to a kind of underground piping connector for crop field trickle irrigation
The handheld positioning device and reference location device of positioning.
Background technique
Crop field drip irrigation technique is common a kind of irrigation technique of high-efficiency water-saving on large area farmland.Trickle irrigation utilizes pipeline
System water supply makes irrigation water at drop-wise, slowly, uniformly, periodically, quantitatively infiltrates crop root system development region, makes crops
The soil in main root system area remains at optimal saturation state, moisture needed for guaranteeing crop growth.The pipe of crop field trickle irrigation
Road system includes the hollow billet for being in ground and the main pipe that divides for being embedded in underground, and irrigation water is used for from hollow billet from dividing main pipe to draw ground
Crops are implemented to irrigate.
Although crop field drip irrigation technique has lot of advantages and is widely used, especially commonly adopt in large area farmland
With but in actual use, but having the following problems: for the ease of mechanized operation, it is desirable that hollow billet in ground and bury
In having to be off when dividing main pipe in annual mechanized farming for underground, and take hollow billet away, so as to divide the soil above main pipe into
Otherwise row cultivation will cause cultivation not comprehensive, leads to the wasting of resources, every hundred mu of ground may slattern one mu because of the presence of hollow billet
Ground.After cultivation is completed, need for whole hollow billets to be connected to again on point main pipe.However, due to cultivation complete after, hollow billet with point
Pipe joint between main pipe is embedded in underground, and searching pipe joint is extremely difficult, especially in large area mechanized farming
On farmland, it is more time-consuming and laborious to need to find hundreds of pipe joint.
A kind of method of traditional searching underground piping connector is: after annual mechanized farming is completed, to pipe-line system
It largely pours water, ground lower interface is found by way of dividing main pipe spilling water.This method waste water resource is not easy to operating personnel's peace
Hollow billet is filled, while needing to expend a large amount of manpower.
Another method is former using RFID (Radio Frequency Identification radio RF recognition technology)
First radio frequency chip is arranged in reason in buried label (wireless radio-frequency positioning marker), stores ID code and pipe on radio frequency chip in advance
Road information etc.；In detection process, electromagnetic wave signal first is sent from Detection location equipment to concentrator marker, the LC on concentrator marker vibrates electricity
Road starts energy storage after receiving signal for radio frequency chip feedback signal, and Detection location equipment receives the radio frequency of LC oscillating circuit transmitting
After the ID code and duct size information that store in chip, specifying information is read after checking treatment, so that it is determined that the position of underground utilities
It sets.
The shortcomings that this method is: radio RF recognition technology is to be attached on underground utilities by mobile reader to read
Label, but mobile reader is that label is read within the scope of a certain distance, therefore it can only be default in a certain distance range
Position joint location, and the position of pipe joint cannot be descended accurate as to position.In addition, this method there is a problem in that: wirelessly penetrate
Frequency signal is weak, and operating distance is short, is unsuitable for applying on buried underground utilities；Radio frequency chip needs special factory's customization, and cost is high
Expensive, structure is complicated for radio frequency identification module, and manufacturing cost is high；Failure risk is high, just will be thorough if radio frequency chip once fails
The location information of pipeline is lost, to cannot detect again in a manner of non-excavating again.
