RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. With the improvement of chip and electronic technology, RFID technology has been practically applied in many fields, including production automation, access control, highway toll collection, parking lot management identification, cargo tracking and so on.
In recent years, the process of urban construction and development has accelerated. Many large and medium-sized cities in China have begun large-scale infrastructure construction, and more and more high-density and unconventional situations have emerged, resulting in a sharp increase in construction site transportation vehicles. disposal brings great pressure. Therefore, the phenomenon of stealing and dumping muck often occurs in society; muck trucks are often overloaded and speeded, driving illegally, and often do not follow the prescribed route; at the same time, due to overloading and speeding, the cover is not strict, causing dust along the road during the entire driving process. , citizens have been complaining constantly, and members of the National People’s Congress and the Chinese People’s Political Consultative Conference have put forward relevant proposals every year. The management pressure of the government management department has been on the edge of extreme. How to effectively control it and reduce its impact on the environment has become a hot issue of current social concern.
The design of this paper is based on RFID The technical construction site cargo vehicle management information system is equipped with loading and unloading work recording equipment at the muck backfill points of each construction site, and the driver wears high-frequency RFID electronic tags on qualified transport vehicles, combined with transport vehicle operation certificate management and fee settlement Management, through the matching of loading and unloading information to realize point payment, and finally realize the whole process supervision of construction site transport vehicles, reduce the occurrence of construction cargo transport vehicles stealing and overturning, prevent illegal cargo transport vehicles from entering, and ensure the normal operation of the legal market. Create a harmonious and beautiful city environment to provide protection.
RFID application in muck truck
The construction site cargo transportation vehicle physical information system based on RFID technology consists of the driver wearing RFID equipment, and the ground handheld RFID. ReaderIt consists of two subsystems and system management software. RFID can be divided into passive RFID and active RFID according to the way of energy supply. Active RFID can provide a longer reading and writing distance, but requires battery power, which is suitable for long-distance reading and writing applications. According to the application frequency, it is divided into low frequency (below 135KHz), high frequency (13.56MHz), ultra-high frequency (860M~960MHz) and microwave (2.45GHz, 5.8GHz) RFID. In the system discussed in this paper, the vehicle driver wears the RFID electronic tag, the electronic tag device adopts the electronic tag of the ISO14443 protocol with a working frequency of 13.56MHz, and the RFID tag adopts a unique code inside, which cannot be imitated. This kind of RFID tag is selected especially in the application environment where the RFID electronic tag is given the unique legality of the identity.
Three checkpoints are set on the ground, and the handheld reader is used to read the RFID worn by the driverelectronic labeldata information. It is deployed at the checkpoint. When the amount of each cargo passes through the checkpoint, the inspector prints out the certificate through the handheld computer with the information on whether the inspection result is qualified. The handheld reader communicates wirelessly with the RFID electronic tag through the antenna, which can realize the reading or writing operation of the tag identification code and memory data. The handheld reader is also loaded with a GPRS wireless data transmission module. The handheld reader stores the information locally after reading the RFID information, and at the same time transmits the transport vehicle information to the information center database through the GPRS data network for recording and storage. The system management software fully considers the construction scale of large and medium cities in the design. The design capacity allows hundreds of handheld readers to upload data and read information at the same time, allowing more than 100 users to query and count system data at the same time. Combining existing technologies, the system finally uses Microsoft’s SmartClient technology combined with WEB to ensure the real-time, rapid response, data concentration, easy management and future function expansion requirements of the entire system. For some statistical analysis data and reports, it can be realized in pure report form, which can facilitate the exchange and sharing of information with other systems.
The data acquisition process of the whole system can be briefly summarized as follows: different gates are set at each construction site and on the way of the transport vehicle, each inspector is equipped with a handheld reader, and the driver’s RFID electronic tag is read on the qualified transport vehicle. information, the handheld reader reads the qualified data information, prints out the certificate and transmits the information to the information management center through the GPRS network and keeps the data backup locally. Under the guarantee of various management systems, the goal of comprehensive and long-term management of construction site transport vehicles is realized.For example, the function of the construction site muck disposal management business is shown in the figure
