Embodiment 1
[0033] A method for realizing the relay communication protocol of urban roadside parking spaces based on the Internet of Things, including a detection node 1 and a convergence node 2, such as figure 1 As shown, the detection node 1 is a geomagnetic sensor installed on the ground of the roadside parking space. Each detection node 1 has a unique node number. Generally speaking, the detection nodes 1 are arranged along the direction of the road, and the sink node 2 is a wireless relay Generally speaking, only one sink node 2 is set in an area, and the specific steps are as follows:

The invention relates to the relay communication protocol of the internet of things, and discloses an urban wayside parking space relay communication protocol implementation method based on the internet of things. The method comprises a plurality of detection nodes and a aggregation node, and includes the specific steps: the detection nodes detect parking spot information, and the detection nodes are served as sending nodes; step 1 to step 4 are executed circularly until aggregation node is detected within a covering range of the sending nodes; the sending nodes send the parking spot information to the aggregation node. The urban wayside parking space relay communication protocol implementation method has the advantages that distribution type of the detection nodes decides communication states of the detection nodes, and network topological information does not need setting up or maintaining. The urban wayside parking space relay communication protocol implementation method is good in fault tolerance, small in information processing amount, little in information transmission amount, little in energy consumption of the detection nodes, and high in application value.
Description
technical field [0001] The invention relates to a relay communication protocol of the Internet of Things, in particular to a method for realizing the relay communication protocol of an urban roadside parking space based on the Internet of Things. Background technique [0002] The development of urban roadside parking spaces is one of the effective methods to solve the problem of urban parking difficulties under the background of my country's increasing car ownership. On-street parking spaces are usually a deep excavation and full use of urban road functions on the basis of ensuring the basic traffic capacity of the road. As a temporary measure, on-street parking can easily meet the needs of short-term parking users and save a lot of time in finding a parking lot and parking in and out of the parking lot. [0003] At present, the main problems in urban roadside parking spaces are that there is a lot of manpower input, different parking charging standards, and it is difficult...
