Low-cost parking lot information sharing system based on LoRa communication technology

Abstract

The invention provides a low-cost parking lot information sharing system based on the LoRa communication technology. The system comprises a gateway, a sensor node and a server, a LoRa wireless sensornetwork is established within the range of a parking lot, and the data of the sensor network are uploaded to a cloud server; the gateway obtains and integrates the data of all nodes in a mobile phonesensor network and sends the data to the server; the sensor obtains the current parking space occupation condition through the sensor; the server receives the parking lot data from multiple gateways and stores the same in a corresponding data table, meanwhile, the server is responsible for providing query and modification interfaces for an external developer, so that different users can customizefront-end pages according to their needs. The low-cost parking lot information sharing system based on the LoRa communication technology provided by the invention is relatively low in power consumption, relatively low in information transmission delay and reasonable in sensor scheme.

Description

technical field [0001] The invention belongs to the application technology of the Internet of Things. Based on the LoRa technology, a single-hop sensor network is organized in the parking lot and combined with a low-cost capacitive parking sensor to obtain the occupancy information of the parking space and share the occupancy of the parking space to the Internet. Background technique [0002] With the rapid development of my country's economy, the number of cars in my country is also growing rapidly. In 2018, the number of motor vehicles in the country reached 325 million, an increase of 15.56 million compared with 2017. At the same time, the number of motor vehicle drivers reached 407 million. , an increase of 22.36 million in 2018. Such an increase in the number of motor vehicles also puts forward more requirements for the growth of parking spaces. However, compared with the rapid growth of the number of motor vehicles, the number of parking spaces built by urban infrastruc...
