A smart city is to use information and communication technology to sense, analyze, and integrate key information of the core system of urban operation, so as to respond intelligently to various needs including people's livelihood, environmental protection, public safety, urban services, and industrial and commercial activities. . Its essence is to use advanced information technology to realize urban intelligent management and operation, thereby creating a better life for the people in the city and promoting the harmonious and sustainable growth of the city.

In many application scenarios of smart cities, RFID technology is playing an important role, bringing great convenience to our lives. So, what are the main application scenarios of these RFID smart cities?

1. RFID intelligent manhole cover management

The inspection manhole covers are connected by RFID technology, and the real-time data collection and management of the physical state, position status and identity information of the manhole covers are carried out. Through wireless sensing technology and RFID technology, the perception layer, network layer and application layer are connected to realize real-time reading, analysis and transmission of data.

The RFID electronic tag is inlaid on the manhole cover after corresponding to the label, and the state of the manhole cover is measured according to the acceleration sensor in the RFID tag. The wireless network management base station scans the manhole cover tags within a management radius of 500-1500 meters in real time, and the tags send inventory information to the base station. The base station transmits to the background of the system, and technically transmits it to the hand-held terminal of the management personnel to perform corresponding processing.

RFID smart manhole cover can realize the following functions:

1. Asset MANAGEMENT

The RFID manhole cover electronic tag has a unique ID number, and a manhole cover corresponds to an ID number (the ID number accurately records the property right unit, contact person, and phone number of the manhole cover), which is convenient for the management department to collect information and deal with the situation. Therefore, through regular real-time inventory, the management department can quickly grasp the state of manhole cover loss.

2. Position detection

With the real-time collection function of RFID and the intuitive municipal floor plan, the management department can check the location and basic attribute information of the area where the manhole cover is located in real time, which is convenient for unified command and dispatch and project maintenance.

3. Anti-theft supervision

According to the pre-designed alarm rules, when the manhole cover is tilted and vibrated due to abnormal prying, the system will trigger the alarm.

4. Alarm linkage

After the alarm information is generated, the system will be linked to the relevant responsible unit, and the responsible person will be notified by SMS or other methods.

5. Data Analysis

Through in-depth mining of big data in the system, data is extracted, aggregated and analyzed from different dimensions, different angles, and different needs, providing valuable data to support better municipal management.

2. RFID Sanitation Trash Can Management

By fixing the RFID electronic tag on the trash can, and entering the relevant information such as the community where the trash can is located and the type of trash can (recyclable garbage, non-recyclable garbage, kitchen waste, etc.) into the RFID electronic tag. Since the RFID electronic tag has a unique tag code, the tagged trash can will have a unique and fixed identity, and there will be no confusion about the trash can.

Install the RFID Reader on the sanitation vehicle. When the sanitation vehicle is recycling garbage, it will read the RFID electronic tag information and confirm the identity information of the trash can. The automatic weighing equipment on the sanitation vehicle weighs the garbage can, obtains the weight information of the recycled garbage, and transmits all the garbage recycling information at this location to the control system, providing a solid and reliable solution for effectively managing garbage recycling and supervising the recycling process. data and decision support.

It is worth mentioning that the system formulates a garbage recycling line based on the RFID tags of different garbage recycling stations. Each garbage recycling station is a marked site. When the sanitation truck collects garbage, it scans the electronic tags of the garbage station to confirm and check the site information. When the sanitation vehicle finishes cleaning the garbage, the RFID reader does not read the corresponding RFID tag information on the line, and will remind the driver which garbage station was missed. Ensure that garbage can be cleaned up in a timely manner, and reduce the occurrence of residents' complaints.

RFID technology also supports timing reminder function. When the RFID reader fails to read the corresponding tag for a certain period of time, it will issue a warning to remind the driver and administrator to dispose of the garbage at the garbage station in time. Provide residents with a clean and comfortable living environment, and reduce mosquito breeding and stinky scenes in summer.

RFID technology can also optimize the recycling route of sanitation vehicles based on the location information of RFID trash cans, saving fuel costs, avoiding congested and cumbersome road conditions during holidays, and ensuring that sanitation vehicles can reach the destination in time to collect garbage. Each garbage site has a corresponding information mark of the person in charge, which can effectively prevent the phenomenon of escaping from posts and crossing posts.

3. RFID Smart Construction Site Application

With the rapid development of urban construction, the management and control methods of construction sites have also been continuously optimized, and more efficient information-based construction methods have received special attention from relevant organizations. Therefore, the combination of RFID technology and Engineering construction is becoming more and more common. It realizes the automation of construction process and real-time accurate data collection.

An RFID electronic tag is attached to the inner side of the helmet, and the identity information and location information of the construction personnel are written into it. Through the whole set of intelligent management system, data support is provided for labor scheduling and safety management, which can greatly improve the efficiency of engineering operations. In addition, by carrying RFID technology, it is also possible to realize the traceable management of building materials such as steel plates and steel components, and build a smart construction site platform for real-time and dynamic collection.

In recent years, with the continuous development and evolution of various technologies, the combination of RFID and BIM, sensing, GIS, AR/VR and other technologies has been used more and more in construction scenarios, which also enables RFID to be used in more and more function in the link.

4. RFID smart medical care

Since the end of 2019, the new coronavirus epidemic has ravaged the world, not only causing a large number of casualties and huge economic losses, but also severely impacting the medical systems of countries around the world. People are calling for more efficient digital medical care Higher and higher. RFID smart medical care uses advanced Internet of Things technology to realize the interconnection between patients and medical staff, medical institutions, and medical equipment, so as to achieve a higher level of informatization.

The application of RFID in medical scenarios has been very common. For example, the identification of patient identity information can be realized through RFID bracelets; the tracking and management of medical waste can be realized through RFID to avoid the spread of virus infection; The traceability management can curb the proliferation of counterfeit drugs...

The use of RFID technology in the medical industry can improve the medical operation process and improve the quality of medical treatment, while improving the efficiency and accuracy of medical work, thereby ensuring the safety of patients' lives and reducing the occurrence of medical disputes. With the continuous evolution of related technologies, comprehensive data sharing will become one of the main development trends in the medical industry, and it will be easier for Hospitals to effectively monitor disease outbreak trends.

5. RFID smart street lights

Connect scattered street lamps through the Internet of Things technology and weave them into a street lamp management network. The operation status of street lamps can be seen at a glance in the background, which will greatly improve management efficiency. At present, both Dalian and Nanjing have promoted the pilot project of RFID street lamp management, opening up a new mode of operation and maintenance of information-based street lamp facilities.

RFID smart street lights are to paste an RFID sign on each street light pole that contains data resources such as the road section information, street light number, area information, etc. When a problematic street lamp is found during the inspection, the inspector only needs to use the RFID handheld terminal to quickly identify the RFID electronic tag information in the street lamp electronic signage, and then upload the fault information and location to the background of the municipal management office in real time and accurately, and report for repair in time. The public can also use their mobile phones to scan the QR code on the electronic signage of street lamps to report problematic street lamps accurately and quickly.
