Description

Detection method for buried position and joint information of joint pipe and The Control appratus of electric fusion joint using RFID}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fusion control apparatus. In particular, the present invention relates to a global positioning system (hereinafter referred to as GPS), an electronic map (hereinafter referred to as GIS), and an RFID non-contact communication method to collect a plurality of information. The present invention relates to an electrofusion joint control apparatus using position information for post-management of a joint pipe (hereinafter referred to as a joint pipe) in which a synthetic resin pipe and an electrofusion joint are fused after the electrofusion operation is completed.

In general, the electrofusion of the synthetic resin pipe by the electrofusion joint is performed by varying the welding conditions including the voltage, current, power and output according to the type of the joint. Therefore, in the case of welding, it is necessary to recognize the welding condition according to the kind of joint beforehand. In order to obtain the welding condition of the joint, an identification resistor having different resistance values according to the welding condition is inserted into the power supply connection part of the joint, and the resistance value of the identification resistor is determined through a test current to the identification resistor before welding. The fusion conditions had to be determined by reading.

In addition, in other types of electrofusion joints, the connection of synthetic resin pipes can be easily performed on-site using melt bonding by heat generation during energization. In particular, the city gas pipe network is usually buried underground. High reliability is required, and in connection with synthetic resin pipes using the above-mentioned fusion joints, information including joint specifications or temperature, and barcodes for encoding and expressing fusion information such as current and energization time during energization are attached. Do it.

However, the above-mentioned electrofusion joints having the above-described identification resistors need different identification resistors for each type of joint. In addition, an environment in which the resistance value of the identification resistor is generated by heat or ambient temperature generated during welding. Depending on the change, it has the disadvantages such as excessive fusion due to the temperature rise of the resistance coil and loss of reliability.

Barcode-attached electrofusion joints have different improvements than the previous method by attaching barcodes differently according to the type of joints, but they require manual work to read barcodes and have low self-reading rate when reading barcode information for electrofusion operations. Foreign material has a disadvantage in that the read rate is significantly reduced when the barcode is damaged.

Moreover, in general, when constructing a pipe network is buried, the construction company in charge of the construction prepares and submits documents such as a construction report and a pipe network embedded topographic map to the ordering company. The ordering company supervises construction work on the basis of the submitted documents. In addition, the ordering company updates the map system by inputting conduit information and joint information into the map system as the map information for the manager to manage the entire pipe network, based on the construction report and the pipe network embedded topographic map, and at the same time, the construction cost. Integration is also possible. In other words, a construction company prepares reports such as a construction report or a pipe network laying topography by hand, and submits it to an ordering company, and an ordering company, the fencer, duct information and joint information to the map system, and construction are based on the report document Work such as integration of costs is performed.

However, a huge economic loss is required for the creation of various documents required for construction and the input of information for updating the map system for pipe network management. Therefore, a method for automating the preparation of such documents and the input of management information is required. In addition, there was a problem of an accident occurrence due to damage of the pipe network embedded in the ground during the post-management and additional construction of the pipe network.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to quickly communicate the information required for the electrofusion joint in a non-contact method of the RFID tag and the RFID reader is adopted in the energization control in fusion construction The purpose is to provide a stable and stable electrofusion control device.

The method of claim 1, The RFID reader A controller for generating a modulation waveform corresponding to the transmission / reception data; A transceiver / receiver for generating a transmission / reception signal based on the modulation waveform; An antenna coil for propagating the transmitted / received signal to the air in the form of microwaves; And a GIS for detachably attaching and transmitting a joint information, fusion information, and / or location information of the RFID tag by a non-contact method to form a synthetic resin pipe network according to the location information. Fusion Joint Control System. The method of claim 1, RFID Tags A tag antenna coil for transmitting and receiving the signal; A power generator configured to generate power based on the received signal; A memory supplied with power in accordance with the power generation unit, and storing memory based on the received signal; And a controller circuit for demodulating the signal, detecting the modulation waveform, and being driven by a power source generated according to the power generation unit, and writing data based on the modulation waveform to the memory. Electrofusion Joint Control Device. In the site where the joint pipe is buried, the GPS satellite signal of the underground pipe joint is buried in the ground, and the GPS receiver is configured to map the first position information indicating the embedding position of the joint pipe to be embedded in the GIS, and the first position of the joint pipe. Claims [1] A method for detecting a buried position and a state of a joint pipe by receiving and reading through an RFID reader by an RFID tag and a non-contact method for storing information and / or state information. Receiving first position information of the joint pipe embedded in the underground map configured in the GIS and reference position information indicating the current position of the operator from the GPS satellites through the GPS receiver and displaying on the GIS; Displaying first position information of the joint tube read and input through the RFID reader in a non-contact manner with an RFID tag mounted on the underground joint tube and displaying it on the GIS as second position information upon input; In order to determine the embedding position of the joint pipe, by comparing the first position information, the second position information It is determined that the joint pipe position information displayed on the GIS is the first position information when the first position information = the second position information. The joint pipe position information displayed on the GIS when the first position information ≠ second position information is determined to be second position information and / or Determining that the first location information = the second location information when the first location information = NULL (0); By comparing the joint pipe position information and the reference position information When the joint pipe position information = reference position information, it is determined that the operator has reached the buried position of the joint pipe and / or Detecting the buried position and / or the status information of the joint pipe, including determining that the smaller one has not reached the buried position of the joint pipe when the comparatively determined joint pipe position information ≠ reference position information. Method of detecting buried position and condition of joint pipe.
