Wireless communication method and system of intelligent parking lot

Abstract

The invention relates to a wireless communication method and system of an intelligent parking lot. The method comprises the following steps that: a variable quantity of each sampling value of one parking space relatively to an initial sampling value is compared with a preset variable threshold value; if the variable quantity is larger than the variable threshold value, the sampling value is reported by using a small cycle; and if the variable quantity is less than the variable threshold value, the sampling value is reported by using a large cycle. The reported sampling value is counted to obtain a second counting value; when the second counting value is larger than a response interval, a wireless router is required to take responses while the sampling value is reported. According to the invention, sampling values are reported by using different report intervals, thereby avoiding reporting of lots of sampling values, reducing the data bulk in a wireless channel, and reducing the channel congestion probability. Furthermore, when the number of the reported sampling values reaches a certain value, the wireless router is required to take responses, thereby reducing the channel congestion probability. Moreover, a wireless parking space detection node is mainly responsible for sensing data acquisition, thereby improving the work efficiency of the wireless parking space detection node.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication method and system for an intelligent parking lot. Background technique [0002] With the continuous development of the economy, the data and frequency of use of motor vehicles have also increased, and the management efficiency and safety of parking lots lag far behind social needs. [0003] In the prior art, a parking lot management system can be constructed by means of a wired transmission network to monitor and manage all parking spaces in the parking lot, but complex wiring work is required in the parking lot, and the construction period is long and maintenance Difficult and expensive to maintain. Since all the parking spaces in the parking lot are located in the wired transmission network, if one of the nodes (the parking space detection device in the parking space) fails, it may affect the normal operation of other nodes in the transmission net...
