Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and examples. The embodiment of the present invention is based on the following model:

[0019] Such as figure 1 As shown, in this model, there are four important parts: cloud service platform; roadside smart sensor devices; vehicles involved in transporting codes, which we call code carriers; management of various roadside smart sensor devices in smart cities The different departments of , called users. Because these departments are the target users of the cloud service platform. When the user needs to update the software of the managed roadside smart sensor device, he can initiate an update request to the cloud service platform, and the cloud service platform accepts the user's update request and the corresponding update code; and notifies the candidate code carrier of the service request, and receives Next, the candidate code carrier will report to the cloud service...

Abstract

The invention discloses a transmission method for realizing code update of perception equipment through a vehicle-mounted network. By using the vehicle equipped with wireless communication equipment as a code carrier, the method propagates the code to be updated to the roadside intelligent sensor equipment, and can realize the software update of the roadside intelligent sensor equipment in a cost-effective manner. The key technology of the present invention is to select the carrier of the spreading code. The method for code carrier selection in the present invention is: according to the history track record of code carrier, calculate the frequency that code carrier passes through each roadside intelligent sensor device and two reference values ​​of the comprehensive trajectory similarity of code carrier. Then use the weight function proposed by the present invention to calculate the weight value of each code carrier. Finally, the code carrier with the largest weight value is selected and added to the selected code carrier set. Through simulation experiment analysis, the method of the present invention can achieve 32.4% increase in code propagation coverage and 23.5% reduction in price and cost compared with the general method.

Description

technical field [0001] The invention relates to the field of the Internet of Things and vehicle-mounted networks, in particular to a cost-effective propagation method for code updates of sensing devices in the sparse Internet of Things through the vehicle-mounted network. Background technique [0002] In recent years, more and more cities have realized the intelligence of the city by deploying a large number of sensors to form the Internet of Things, which we call "smart cities". The Internet of Things (IoT) makes it easier to collect data by using a large number of devices with integrated sensors. It provides a new approach to address complex sensing applications, such as telemedicine systems, intelligent traffic management systems, and environmental monitoring systems, etc. These sensor-based devices can be deployed in large numbers in the area to be monitored to obtain data as required by the application. With the increase in the number of sensing devices, the amount of...
