Problems solved by technology

The OBUs in the prior art are powered by solar cells. Generally speaking, when the solar cells in the OBU are fully charged, they can maintain the communication between the OBU and the RSU for about 100 times. RSU communication, it is very likely that the power of the solar battery in the OBU will be exhausted in a short period of time, which will cause the OBU to fail to work, thus affecting the charging of the vehicle

Abstract

The invention discloses an information exchange method of an open parking lot. When the parking status of the parking space of the open parking lot changes, the RSU communicates with the OBU again, which can avoid the continuous communication between the RSU and the OBU and thus lead to the power consumption of the solar battery in the OBU. exhausted situation. The information interaction method of the open parking lot of the present invention includes: S1: when the parking space monitoring device detects the change of the parking space condition of the open parking lot, it generates information including the position of the parking space where the parking space condition changes, which is defined as change information; S2: is in The RSU in the closed communication mode enters the communication interaction mode, detects and determines the changed vehicle according to the change information, and performs information interaction with the OBU installed on the changed vehicle; S3: The RSU in the communication interaction mode enters the closed communication mode.

Description

technical field [0001] The invention relates to the field of information interaction of parking lots, in particular to an information interaction method of an open parking lot. Background technique [0002] ETC (Electronic Toll Collection) is the meaning of non-stop electronic toll collection system. Through the microwave-specific short-range communication between the vehicle-mounted electronic tag installed on the vehicle windshield and the microwave antenna on the ETC lane of the toll station, computer networking technology and The bank conducts background settlement processing, so as to achieve the purpose of paying road and bridge tolls without stopping when vehicles pass through the road and bridge toll stations. [0003] An open parking lot refers to a non-completely closed vehicle parking area such as on-street or roadside. With the development and popularization of ETC technology, more and more open parking lots use ETC technology to determine the parking situation o...
