Description

RFID (radio frequency identification) tag matching method and device for tubular pile

Technical Field

The invention relates to the technical field of radio frequency identification, in particular to a method and a device for matching an RFID (radio frequency identification) tag for a tubular pile.

Background

When the existing production line of a tubular pile factory is used for producing tubular piles, the following three process flows are adopted in common use: the traditional horizontal or longitudinal process flow, the conveying process flow of a pipe die chain machine and the pumping and distributing process flow. Various automatic devices are used for the production of various types of tubular piles in the processes of tensioning, roll welding and the like in a workshop, but manual input and paper form recording are still adopted on site to set production specifications, record and manage production quantity and the like. Therefore, the production and management modes in the existing pipe pile industry fall behind, the consumption of manpower and material resources is high, the production efficiency is extremely low, and the management efficiency is not high.

The invention has the advantages of scientific and reasonable structure, safe and convenient use, simplified process flow, capability of moving the position of a pipe die and carrying out reverse flow production by the characteristics of a material distribution process, connection of two production lines, formation of a pipe die for cyclic utilization of the pipe die by forming two production lines, no need of adding equipment, low investment, no need of a transfer tensioning device, lower labor intensity, higher production efficiency and capability of solving the problem that the existing pipe die factory needs to swing and turn the pipe die in production, further, the problems of accidents and low production efficiency are easy to occur.

Chinese patent publication No. CN205875144U discloses a large concrete precast tubular pile with an RFID electronic tag, but the problem that the RFID tag cannot identify and match before demoulding after the reinforcing steel bars are placed in a cage is not considered.

At present, a pipe pile is usually manufactured in a semi-mechanical mode of hoisting and conveying through a crane, wherein working fields such as hook scraping, hook removing, mold stripping, assembling, cleaning, mold release agent coating, mixed soil filling, mold closing, tensioning and the like are small, the pipe pile is not unfolded, long in time consumption and high in manufacturing cost, and a large number of workers gather in the process, so that the problems that the production efficiency is difficult to improve, the labor intensity of the workers is high, production safety accidents are multiple, and the manufacturing cost is high are caused. The existing pipe pile manufacturing method also has the following problems:

the production informatization management level is low: taking the tensioning procedure as an example, the operator of the field tensioning machine can select a manual or automatic mode. When a manual tensioning mode is used, tensioning pressure and time cannot be accurately controlled, and unstable quality factors are caused. Some degree of out-of-specification operation may occur. An operator adopts an original operation panel, only manual selection and input can be carried out, information management in the production process of the tubular pile is not facilitated, and informatization and intelligent transformation is urgently needed on site. In the production process, when the type number of the pipe pile is adjusted, the technological parameters need to be adjusted again, so that errors are easy to occur, and the working efficiency is low.

Lack of effective management and control of production materials: the field production materials need manual management and cannot be pulled to produce through system guidance. Meanwhile, the existing pipe pile production line needs manual monitoring or setting for material metering, mold model management, prestress tension parameter setting during production, maintenance monitoring and personnel operation.

The information system is complex to dock: although the existing stretching machine controller has storage records, files must be copied manually for viewing, and management of data is time-consuming, lagged and prone to errors. The efficiency of the tubular pile is low in the quality tracing process, and the reason for the problem in the production process cannot be traced in time.

Tag read is limited: the RFID label on pipe die and the steel reinforcement cage can be read before the reinforcing bar goes into the cage, but because the shielding of impurity such as cement after the reinforcing bar goes into the cage, lead to unable RFID label of reading the steel reinforcement cage, therefore the label has the restricted problem of reading.

The setting to the RFID label includes the three kinds of modes that set up on pipe die, steel reinforcement cage and staff's drop, specifically as follows:

first RFID usage (RFID tag on tube mold): in the production process of the pipe pile, a tooling jig (including but not limited to the pipe die) on a pipe pile production line is managed by arranging an RFID label on the pipe die.

Each pipe die is provided with at least one RFID label, and corresponding position information is obtained through the arranged RFID reader. Meanwhile, an RFID reader is arranged in a storage warehouse of the pipe die or the RFID reader is arranged in the reinforcing steel bar die entering stage of the production flow. When a certain type of pipe pile needs to be produced, the model information on the RFID tag of the pipe die is read through the RFID reader according to the production plan obtained by the production management server, and the corresponding pipe die is extracted and placed on a production line for production and use. Meanwhile, the information is read in real time through the RFID reader arranged on the production line and is transmitted to the production management server, and the state of the pipe die on the production line is mastered. In the subsequent production process, the production parameters of the corresponding tubular pile are obtained according to the RFID tag on the tubular mould and the RFID reader used on the equipment in each production stage, and various kinds of production information of the station are transmitted to the production management server through the control terminal (including the RFID reader) in the production process.

When a certain type of pipe pile needs to be produced, a reinforcement cage with a corresponding specification is extracted according to a production plan on a production management system, and an RFID reader in a control terminal reads an RFID tag of the reinforcement cage to confirm that the reinforcement cage is lifted out of a warehouse and placed on a production line for production.

In the subsequent production process, various production information of the tubular pile is transmitted to a production management server through a data acquisition module according to the RFID label on the reinforcement cage and the RFID reader used on the equipment in each production stage. The method is characterized in that RFID tags are installed/set on the reinforcement cage before production, the production data of the tubular pile is read and written through RFID readers arranged at all stations on a production line, one RFID tag is arranged in one tubular pile after production to record the production data of the tubular pile, and the production data of the tubular pile comprises the model of the tubular pile, the production station, the position information of a warehouse, the information of a responsible person, the production time, the using equipment, the adopted process data and the keeping mode.
