Today, with the rapid development of science and technology, everything is moving in the direction of intelligence, such as smart home appliances, smart homes, smart watches… Technology has given people great convenience in life, but we have also seen that while the tentacles of technology continue to expand , A large number of scattered infrastructures still continue the most primitive management methods, and people still often face the embarrassment of being out of reach of intelligence.
Although the slogan of building smart transportation is always heard, everyone will more or less face the following “traffic unsmart” situation: when going out and encountering emergencies, they can’t report their accurate directions when they ask for help; in the city I couldn’t find a public toilet after driving for half an hour; the street light at the entrance of the community had been broken for several days, and I had not seen repairs. I had to remind myself every time I went out and so on. We take the most basic traffic lighting equipment as the entry point, and talk about how the street light Internet of Things helps smart transportation and even smart cities?
1. RFID technology has been successfully applied to street lamp management
With the development of the city, the function of street lights is not only limited to lighting, but gradually evolved into a part of the city’s image. Citizens have put forward higher requirements for urban construction, road lighting and landscape lighting; government departments hope to modernize urban lighting management and make urban management and environmental beautification reach the leading domestic level. Faced with more and more street lights, the management problems gradually emerged.
First, traditional street lamp management is expensive and inefficient. Street lights are scattered, and registration, maintenance, and maintenance require a lot of manpower and material resources. The traditional management method relies on manual inspection and troubleshooting. Each inspection must not only check the lighting, but also check the safety of the shaft and base, as well as the billboards or banners on the light poles. If there is a unit construction nearby, inspectors should also strengthen inspections to ensure the safety of underground cables. These inspection items only rely on manual information to be collected by hand, which is not only inefficient, but also prone to omissions and errors.
Second, there are cases of inadequate inspections, missed inspections, and delayed inspections. Inspection and maintenance of street lights are usually carried out at night. Affected by the light conditions, inspection personnel are prone to negligence, such as improper inspections and missed inspections. Coupled with the widespread distribution of street lights, it is difficult for inspectors to perform inspections once a day. It is easy to cause the street lights on a certain road to be broken for many days, and there is still no maintenance. The lag of inspections brings great inconvenience to residents’ travel safety.
Third, the location of street lights is difficult to locate, which increases the difficulty of applying for repairs. There are more than tens of thousands of light poles in each city. Due to the geographical environment, the layout of roads, streets, and alleys is basically irregular. For a long time, citizens can only report building numbers or surrounding buildings in the process of repairing street lights. Positioning, maintenance personnel also need to inquire and find the location accurately when looking for repairing street lights, which leads to difficulties in repairing street lights. In addition, some road environments are complex, such as bridges, tunnels, areas with many high-voltage wires or highway intersections, etc. It is difficult to determine the specific location of street lights. It takes time and effort to find them. It is difficult to maintain and manage these street lights by manual inspection. higher cost.
Fourth, there is a lack of comprehensive control over the location and quantity of street lighting equipment. The manual inspection method lacks the evaluation of inspection quality and the inquiry and statistics of inspection work. It is difficult for management personnel to understand the condition of street lights in a timely, accurate and comprehensive manner, and it is difficult to formulate the best maintenance and repair plan.
The various shortcomings of manual inspections are increasingly being criticized. How to use modern technology to solve the problem of street lamp management and build smart transportation and smart cities has become a social thinking.
The development of the Internet of Things and RFID technology has brought solutions to the management problems of street lights. The Internet of Things relies on modern technologies such as RFID technology, Internet technology, and communication technology to realize the “connection of things”. If you connect scattered street lights and weave them into a street light management network, the operation of the street lights can be seen at a glance in the background, 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.
2. Scientific and technological innovation of street lamp electronic signage technology
Street lamp electronic signage isRFIDA practical and innovative use of technology. In traditional traffic applications, the well-known automotive electronic tags are generally affixed to the windshield of the car and are in a mobile state, while the reader is relatively fixed on the gantry. In street light management, the situation is just the opposite. The electronic tag is fixedly affixed to the telephone pole. The reading and writing equipment can be handheld or vehicle-mounted, that is, the reader and antenna are installed on the inspection vehicle, and the electronic tag is read while the vehicle is running.
The vehicle-mounted read-write device is an innovation. How to ensure the feasibility and convenience of actual use of vehicle-mounted devices, readers and antennas, as well as the characteristics required by the aerodynamics of the car when driving, puts forward requirements for the performance and device of the equipment. Instinctively developed a set of on-board reader and antenna device, a general patrol car can be transformed into a modern street lamp inspection tool vehicle with low space occupation and high resource utilization by installing this device.
This vehicle-mounted reader and antenna device can install and fix the reader and antenna on the inspection vehicle. The staff can open, close and control the work of the reader and antenna while sitting in the vehicle, and store or store it freely. Extend the reader and antenna, and adjust the extension height, level, direction and pitch angle through the universal rotating device as needed, so that the vehicle becomes a mobile read-write base station for the street lamp electronic signage system.
As shown in the figure, the reader and the antenna integrated machine are installed on the roof of the car, and the host of the radio frequency identification reader is placed in the car, and the two are connected by a short length signal line. The reader and antenna integrated machine is fixed on the universal rotating device, and the universal rotating device is installed above the folding arm connected to the top bracket of the car.
The controller, on-board computer terminal and peripheral equipment are placed inside the vehicle. Among them, the controller is responsible for powering and controlling the folding arm and the all-in-one machine; the on-board computer terminal and peripheral devices are responsible for receiving and sending the data of the all-in-one machine to the background. When inspectors take the vehicle for inspection, the on-board reader can accurately scan the electronic signs on the light poles, and the data information read and written is transmitted to the on-board computer terminal in the car through the data cable, or transmitted to the background through wireless means The server realizes rapid inspection and rapid location of problem street lights, and achieves the purpose of operation and maintenance of informationized street light facilities.
3. The Internet of Street Lights Weaves a Smart Transportation Network
The application of street lamp electronic signs is of great significance. For street lamp management departments, the street lamp electronic signage system greatly facilitates the management and maintenance of street lamps.
First of all, the street lamp electronic signage system adopts advanced RFID technology, which can realize the automatic identification of street lamps during inspections and ensure the in-place rate of inspections. At the same time, it standardizes the work content of the inspection personnel, avoids the occurrence of wrong inspections and missed inspections, and helps to complete inspection operations more efficiently. The reader can accurately read the street light pole signs, which can quickly locate faulty street lights and facilitate inspection personnel to troubleshoot, thereby reducing the time to find faulty street lights and improving work efficiency.
Secondly, inspection vehicles and handheld terminals reduce the labor intensity of inspectors and realize “paperless inspections.” Use a vehicle-mounted reader or handheld terminal to directly upload data, and the data is detailed, which can effectively improve the real-time and accuracy of asset inventory.
Finally, the street light electronic signage system simplifies the inspection work process, realizes the standardization of street light management, improves the precision of the inspection, and facilitates historical query. Through the street lamp electronic signage system, the number of street lamp control boxes and light poles can be accurately counted, and the management department can count the total number of street lamps, the total power, and calculate the total length of cables and other related data. Relying on the street lamp electronic signage system, the management department can also establish a street lamp management and maintenance account, improve the management of electrical materials, and conduct supervision and random inspections according to the actual situation.
As far as city management is concerned, the street lamp electronic signage system enhances the service level of city management.
The street lamp electronic signage system makes full use of the street lamp’s positioning function. In some road sections without house numbers, the sign can provide accurate positioning services. For example, if you are looking for someone by express, you can rely on the number on the sign of the street light pole to quickly locate it. Or a QR code containing coordinates and other information is printed under the street light sign, and the light pole number and corresponding coordinates, elevation and other information are accurately recorded on this QR code. When an individual needs to determine his own location, turn on the smart phone Scan the QR code, and you can display your exact location and surrounding floor plans on the phone map. This positioning method is very practical for foreign population and tourists in scenic spots.
In addition, the street lamp electronic signage system is fully integrated with the 110 alarm platform and the 120 emergency platform, and the street lamp number is imported into the electronic map of the police geographic information system. In the event of an emergency, when a person cannot tell his location, he can find the nearest street light pole, report the light pole number or upload a QR code, and various alarm centers, emergency centers, etc. can immediately determine the location.
The most important thing is that the street lamp electronic signage system has built the street lamp Internet of Things, which has made outstanding contributions to the construction of smart cities. By scanning the QR code on the electronic signage of street lights, you can quickly know the real-time traffic conditions around you, help drivers avoid congested road sections, save time, and effectively guide traffic flow. At the same time, inquiries and navigation of nearby bus station information, surrounding commercial parking lot information, and commercial store information can all be done through street light electronic signs. It is convenient for advertisers to carry out precise marketing for users in the business district.
The application of street lamp electronic signage system greatly facilitates street lamp asset management, and the various livelihood services derived from it have brought various conveniences to people. From this to the other, we envision that in the entire transportation system, a large number of road cameras, road guardrails, and road billboards can also learn from the management of street lights to truly promote the process of smart transportation?
