Low power consumption parking space state collection method based on wireless sensor network

Abstract

The invention discloses a low-power-consumption parking space state collection method based on a wireless sensor network, and belongs to a parking space state collection method based on a wireless sensor network. The invention solves the technical problems of providing the low-power-consumption parking space state collection method based on the wireless sensor network, and adopts the technical scheme that a coordinator node sends a broadcast at the beginning phase of the operation period of the coordinator node; after receiving the broadcast, a sensor node sends parking space information to the coordinator node within the preset time; and the coordinator node uploads the parking space information to an upper computer via a wired or wireless network and downloads a related command to the sensor node from the upper computer. The low-power-consumption parking space state collection method based on the wireless sensor network is suitable for the wireless communication network.

Description

technical field [0001] The invention discloses a method for collecting the state of a low-power parking space based on a wireless sensor network, and belongs to a method for collecting the state of a parking space based on a wireless sensor network. Background technique [0002] With the improvement of human living standards, vehicles have gradually become a necessity for people's lives. However, people's demand for parking spaces in today's cities is gradually surpassing the demand for vehicles. The difficulty in the construction of parking spaces is an uncontrollable factor that causes the supply of parking spaces to exceed demand. The inability to effectively utilize parking spaces and cause waste is a controllable factor for the above problems, which makes a real-time collection of parking space status information and uploads the parking space status information to remote terminals so that people can use parking spaces in a timely and effective manner. The method came in...

[0002] With the improvement of human living standards, vehicles have gradually become a necessity for people's lives. However, people's demand for parking spaces in today's cities is gradually surpassing the demand for vehicles. The difficulty in the construction of parking spaces is an uncontrollable factor that causes the supply of parking spaces to exceed demand. The inability to effectively utilize parking spaces and cause waste is a controllable factor for the above problems, which makes a real-time collection of parking space status information and uploads the parking space status information to remote terminals so that people can use parking spaces in a timely and effective manner. The method came into being, and the wireless sensor network technology is more and more applied in the parking space status collection system because of its advantages of wireless transmission and low installation cost. When the wireless sensor network is used to transmit the parking space status information, usually the Each sensor node is buried under the parking space to collect the data of the parking space, which puts forward higher requirements on the power consumption of the sensor node, the stability and reliability of network transmission;
