Description
Technical field
The present invention relates to a kind of location, earth mat inspection management system and method that is used to confirm to imbed the underground nonmetallic ion earthing device that can be recycled, specifically be meant non-metallic ion grounding body management method and system based on the RFID technology.
Background technology
At present, known ground connection series products mainly contains metal species and non-metal kind two big classes.The grounding body of metal species mainly contains steel and copper material, and the non-metal kind grounding body mainly is an earthing module, and the resistance of falling of these two kinds of earthing materials mainly is to rely on the contact area of body and the earth with resistance; Local resistance reducing effect for soil resistivity is high is also very limited, and steel in placing into the soil after because " macro cell corrosion " principle; Corrosion of steel is very serious, and ground resistance bounce-back can't safeguard to have only and build earth mat again; And the processing technology of earthing module has determined product will disintegrate through bubble, extruding after underground imbedding, and simultaneously serious corrosion also can take place the metal pole piece, therefore also can't carry out later maintenance; Hinder to rebound also to have only with finding and build earth mat again, therefore occurred copper ion ground rod and non-metallic ion grounding body on the market, the copper ion ground rod is at the inner interpolation of copper pipe ionic material; Use back its resistance reducing effect of proof, earial drainage, anticorrosion all fine, can add ionic material and safeguard, make its stake resistance return to the resistance value when building as finding ground resistance bounce-back; But because it costs an arm and a leg, large-area use has also received very large restriction, and has wasted national a large amount of non-ferrous metal; Another kind of nonmetal bulk resistor through the nonmetallic ion class earthing device (having obtained national patent, patent No. ZL200920243412.2) that forms by a firing is low, is equivalent to metal; Discharge capacity is strong, imbeds can not disintegrate, corrode after underground, and it draws metal electrode after using certain time limit as corrosion takes place can change, need not to change whole ground connection product in the scene; Product to fall resistance mechanism identical with the copper ion ground rod, As time goes on, the electrolytic ion material of grounding body inside can reduce until using up gradually; Stake resistance also may rebound; At this moment only need to the inner electrolytic ion material that adds of grounding body, stake resistance can return to original grounding resistance over time, and this grounding body is because low price; Later stage can safeguard; And maintenance cost is quite low, has practiced thrift national a large amount of non-ferrous metal simultaneously and to the various expenses that earth mat is built repeatedly, has obtained excellent popularization.But; Because grounding body is nonmetal and is embedded in underground; Wanting the later stage safeguards just and must make things convenient for, accurately find grounding body, and can effectively manage the ground connection physical efficiency that is embedded in the soil, thus realization to the ground connection system management and carry out later maintenance; Realize practicing thrift a large amount of later stage ground network reconstructions and safeguard fund; But, also have no a kind of system and method accurately to locate in the market, inspection and net management over the ground to buried non-metallic ion grounding body.
Summary of the invention
The objective of the invention is to address the above problem; A kind of non-metallic ion grounding body management method and system based on the RFID technology is provided;, can safeguard fast stake resistance when rebounding; Thereby can analyze the soil resistivity situation of this ground network area and hinder the problem that bounce-back just can only be built again with avoiding, practice thrift great amount of manpower and expense.
The object of the invention is realized through following technical proposals:
Non-metallic ion grounding body management method based on the RFID technology may further comprise the steps:
(A) set up the topological network of non-metallic ion grounding body; The RFID electronic chip, is installed each non-metallic ion grounding body in burying each non-metallic ion grounding body a little underground; On the RFID detector, connect Temperature Humidity Sensor; Each non-metallic ion grounding body is buried RFID detector of a correspondence underground, and each RFID detector is communicated by letter with management work station through the usb data line, and management work station communicates by letter with data center through network;
(B) management work station receives the data message that RFID electronic chip that the RFID detector reads sends through the usb data line, and the data message that receives is calculated, and management work station transfers the data of data center through network; And the data of result calculated and data center are compared; If comparative result is improper, send operational order, carry out attended operation by the maintainer; If comparative result is normal, then with data storage to data center.
A plurality of burying underground in certain zone a little is embedded with a plurality of non-metallic ion grounding bodies; When burying underground, the RFID electronic chip is installed in each non-metallic ion grounding body, is connected with Temperature Humidity Sensor on the RFID detector; Bury RFID detector of a correspondence underground for one; Each RFID detector is communicated by letter with management work station through the usb data line, management work station through network with data transmission to data center, management work station can transfer this that be stored in data center and bury a historical data underground; Management work station calculating is also judged the whether normal of non-metallic ion grounding body; And outwards send operation maintenance command, and operating personnel bury a little specific non-metallic ion grounding body according to the content of operational order underground to appointment and safeguard, thus the soil resistivity situation that can analyze this ground network area is practiced thrift great amount of manpower; Hinder the problem that bounce-back just can only be built again with avoiding, reduced the maintenance cost of earthing device.
Further say; In the said step (A); When in non-metallic ion grounding body, the RFID electronic chip being installed; Through the RFID detector RFID electronic chip is carried out write operation, in the RFID electronic chip, write non-metallic ion grounding body ID, the date of production, product type, device coding, date and time information puts into operation.The RFID detector has following function: the RFID detector can be accomplished reading in real time the RFID electronic chip; The RFID detector can basis and the RFID electronic chip between reflected radio signal power calculate non-metallic ion grounding body and bury the ground degree of depth; The RFID detector has certain data storage capacities; The RFID detector can carry out data transmission through USB interface with the back-stage management workstation; The RFID detector can with GPS positioning system fusion application, make geo-location more accurate; The requirement system has high reliability and high integration; Processing capability in real time and data transmission property preferably accurately; When burying the RFID electronic chip underground; The RFID electronic chip is write relevant informations such as non-metallic ion grounding body ID, the date of production, product type, device coding, the date of putting into operation through the RFID detector, so that when subsequent calls, can transfer at any time.
Further say; (B1) the RFID detector sends radiofrequency signal to the RFID electronic chip; Behind the RFID electronic chip received RF signal, the RFID detector converts accepting state into, and the RFID electronic chip obtains the energy of radiofrequency signal and outwards sends radiofrequency signal; The service data of radiofrequency signal load non-metallic ion grounding body, receive by the RFID detector load non-metallic ion grounding body service data radiofrequency signal and store;
