A wireless parking lot data acquisition system based on dual sensors

Abstract

The invention discloses a wireless parking lot data acquisition system based on double sensors, which includes a parking space information detection module, a wireless transmission module, a regional center and a cloud database; a parking space information detection module is set at each parking space to collect the data of the parking space Whether the vehicle has situation information, encode the collected information and transmit it to the wireless transmission module; the wireless transmission module receives the data information transmitted by the parking space information detection module and transmits the information to the regional center, and the regional center receives the wireless transmission The data information transmitted by the module is decoded and then sent to the cloud database. The cloud database updates and stores the received information in real time, and the user accesses the cloud database to query the parking space information.

Description

technical field [0001] The invention belongs to the technical field of detection of parking spaces in parking lots, and in particular relates to a dual-sensor-based wireless parking lot data acquisition system. Background technique [0002] At present, in urban construction, a large number of parking lots are needed to facilitate users to park vehicles, but in the actual parking process, users need to enter the parking lot to find parking spaces, which wastes users' time and there is no parking space phenomenon. The existing large underground parking lot system cannot provide parking space information data in real time, and there are certain limitations, mainly manifested in: 1. The existing large underground parking lot uses infrared sensing technology, which uses a single sensor, and the accuracy is not high. The light has a great influence. At the same time, although the information of the parking spaces is collected and displayed with red and green lights, the data is no...

Problems solved by technology

[0002] At present, in urban construction, a large number of parking lots are needed to facilitate users to park vehicles. However, in the actual parking process, users need to enter the parking lot independently to find parking spaces, which wastes users' time and there are no parking spaces.

The existing large underground parking lot system cannot provide parking space information data in real time, and there are certain limitations, mainly manifested in: 1. The existing large underground parking lot uses infrared sensing technology, which uses a single sensor, and the accuracy is not high. The impact of light is great. At the same time, although the information of parking spaces is collected and displayed with red and green lights, the data is not summarized, and the data lacks systematic processing and storage.

2. The parking space information of the existing large parking lot is not obvious. When users are looking for a parking space in the parking lot, the parking spaces within the line of sight are limited, and the light of the large underground parking lot is very poor. Many users spend a lot of time in the parking lot To find a suitable parking space, this wastes a lot of time and is very inefficient
