Problems solved by technology

Especially when parking, because there is no response instruction on each road section, it is usually guided manually, and parking is very inconvenient. It often happens that some road sections cannot find parking spaces, while other parking spaces are empty for a long time , resulting in a lot of waste of space, but also brings great inconvenience to car drivers

Embodiment Construction

[0012] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the parking space sensing system based on RFID technology includes several ultrasonic sensors 2 installed on the parking space 1. In principle, only one ultrasonic sensor 2 needs to be installed in each parking space, and each ultrasonic sensor 2 is connected with an RFID tag. 3 connection, the RFID tag 3 communicates with the RFID reader 4, the RFID reader 4 is provided with a 3G communication interface, the RFID reader 4 communicates with the system service 5, and the system server 5 connects with the display screen 6.

[0014] The ultrasonic sensor 2 is mainly used to sense whether there is a vehicle parked in the parking space. The ultrasonic sensor is a sensor developed by utilizing the characteristics of ultrasonic waves. It uses the acoustic wave medium to perform non-contact and wear-free detection of...

Abstract

The invention discloses a parking space sensing system based on RFID technology. The RFID reader is connected in communication with the system server, and the system server is connected with the display screen. Each ultrasonic sensor is connected with an RFID tag, the RFID tag is connected in communication with the RFID reader, the RFID reader is connected in communication with the system server, and the system server is connected with the display screen. The system can realize mutual perception between people and parking lots, shorten the parking time of drivers, effectively improve the utilization rate of parking spaces, and realize the unified management of parking spaces in the whole city through this system.

Description

technical field [0001] The invention relates to a parking space sensing system, in particular to a parking space sensing system based on RFID technology. Background technique [0002] Radio Frequency Identification (RFID) technology, also known as electronic tags, is a communication technology that emerged in the 1990s. It can identify specific targets and read and write related data through radio signals without identifying the system and specific targets. Mechanical or optical contact is established between them. The integrated circuit inside the RFID tag can be driven by receiving electromagnetic waves of a specific frequency. When the tag receives a signal of sufficient strength, it is woken up so that it can send data to the reader. These data include not only ID numbers (globally unique codes), but also data pre-existing in EEPROM (electrically erasable programmable read-only memory) inside the tag. RFID is considered to be one of the top ten technologies that will ...
