Therefore, through regular real-time inventory, the management department can quickly grasp the drain status of the manhole cover.
· Location detection-RFID’s real-time collection function, with intuitive municipal floor plans, the management department can view the location and basic attribute information of the jurisdiction where the manhole cover is located in real time, which is convenient for unified command and dispatch and project maintenance.
· Anti-theft supervision-According to the pre-designed alarm rules, when the manhole cover is tilted and vibration induced by abnormal prying, the system will trigger an alarm. When the manhole cover is in a normal state, the electronic tag is in a dormant state.
· Alarm linkage-After the alarm information is generated, the system linkages to the relevant responsible unit and informs the responsible person by SMS or other methods
· Big data analysis-through in-depth mining of big data in the system, data extraction, summary analysis from different dimensions, different angles, and different needs, provide valuable data to support better management of municipalities.
Smart street light management
The Internet of Things relies on modern technologies such as RFID technology, Internet technology, and communication technology to realize the “connection of things”. Connect the scattered street lights and weave them into a street light management network. The operation of the street lights can be seen in the background at a glance, which will greatly improve management efficiency. At present, Dalian and Nanjing have promoted the pilot projects of RFID street lamp electronic signage technology, opening a new mode of operation and maintenance of informationized street lamp facilities.

RFID street light electronic sign, as the name implies, is to paste an RFID sign containing data resources such as road section information, street light number, area information, etc. on each street light pole. When a problematic street lamp is found during the inspection, the inspector only needs to use the handheld terminal to quickly identify the RFID chip information in the street lamp electronic identification plate, and then the fault information and location can be uploaded to the background of the municipal management office in real time and accurately, and repairs can be reported in time. The masses can also use their mobile phones to scan the QR code on the electronic signage of the street lamp to report the problem street lamp accurately and quickly.
Intelligent public transportation management
1. Electronic stop sign, intelligent stop reporting
The traditional electronic bus stop sign system uses on-board GPS to implement vehicle stop reporting. After years of operation, three challenges are faced in practical applications:
1) Large investment and high operating cost. Each vehicle needs to invest in on-board GPS+GPRS, and a monthly SIM card communication traffic fee is required. Due to the large number of vehicles, this operating cost is high.
2) The power consumption is large, and the battery of the bus is lost, causing the entire GPS station reporting system to be paralyzed.
3) GPS cannot work accurately on rainy days.
RFID electronic stop signs use active RFID technology. By installing RFID readers on the electronic stop signs and installing RFID electronic tags on the vehicles, when the bus passes through the station, the station actively recognizes the bus RFID electronic tag data and transmits it to the control center as a report. Basic data for functions such as stations.

Intelligent control of electric bicycles
The electric bicycle intelligent management and control system based on RFID radio frequency technology takes the electric bicycle electronic number plate as the core, and the radio frequency chip is built into the electric bicycle number plate, and the vehicle dynamic information is automatically uploaded to the background system in real time through the collection equipment installed at the intersection and road section .
(Application case: Shanghai applies RFID to control electric bicycles, source: Shanghai release)
Traffic illegal capture system is mainly composed of four parts
One is the “electronic” number plate, which replaces the original electric bicycle number plate by installing a number plate embedded with an electronic chip on the electric bicycle, and collects relevant information about the vehicle and the owner during the process of licensing;
The second is collection equipment. By deploying fixed collection equipment in areas with high incidence of traffic violations of express delivery and takeaway electric bicycles, real-time collection of the driving trajectory of electric bicycles can be used to determine whether there are traffic violations;
The third is video assistance. In addition to the use of RFID to collect illegal traffic trajectories of electric bicycles, currently, the traffic police department combines with road video monitoring equipment to assist RFID-collected illegal data on electric bicycles to carry out off-site law enforcement;
The fourth is the data cloud. Through the establishment of a proprietary data cloud, the basic data information of express delivery and takeaway electric bicycles in this city will be gathered and management work will be carried out.
In addition, in municipal management, Internet of Things technologies such as RFID are also widely used in application scenarios such as municipal assets, gas equipment, gas facilities, underground pipe networks, power facility safety, and municipal hazardous facility management.
This year, the new infrastructure that has received much attention is included in the government work report for the first time. “Strengthen the construction of new infrastructure, develop a new generation of information networks, expand 5G applications, build charging piles, promote new energy vehicles, stimulate new consumer demand, and promote industrial upgrading.”
“New infrastructure” needs the support of new technologies, and Internet of Things technologies such as RFID will inject vitality into the construction of new infrastructure. So, what kind of good news can the new infrastructure bring to RFID and other Internet of Things technology companies? Can related companies catch this wave of good news? We will wait and see!
