Abstract: A device-cloud collaboration method, platform, and apparatus, where the device-cloud collaboration method includes: obtaining current spatial information of each target terminal; tracking a spatial information change of each target terminal, to obtain a spatial information change status of each target terminal; and determining, based on spatial information-based arbitration conditions preset for different target mobile applications and the spatial information change status of the target terminal corresponding to the different target mobile applications, whether to trigger subsequent operations related to the different target mobile applications. The device-cloud platform blocks a change in which the user is not interested through arbitration of a spatial information change of the user, and provides an appropriate spatial information change to a mobile application, or triggers a subsequent operation of the mobile application.

Abstract: Disclosed is a simulation design method for bay layer devices of a smart substation. Application layer modules of two network structures store identity tags of each other's application layer modules respectively, so that a simulation model of the bay layer devices has ports of both network structures and can realize data sharing. The simulation model of the bay layer devices can process SV messages, GOOSE messages and MMS messages simultaneously. An interface layer is additionally configured between an application layer and a data link layer to allow data to be directly mapped to the data link layer from the application layer, so that received or transmitted messages contain actual electrical quantity information. The invention provides model establishment methods of two network structures, thus not only suitable for simulation of the bay layer devices, but also suitable for simulation of station control layer devices and process layer devices.

Abstract: Disclosed is an online marketplace system that includes a marketplace platform, a database, and an analytics module. The marketplace platform includes a customer portal and a business portal, wherein the customer portal is used by a customer to submit a request for quote and the business portal is used by selected vendors to input offers or bids. Once the customer selects a vendor to fulfill a product and/or service request, the platform prompts the customer to complete a survey before confirming the purchase. The analytics module gathers the survey data as well as other relevant market data to generate a report for the vendors, whereby the vendors can use the report to assess their performance and make improvements to their businesses. The analytics module is further configured to provide market data to the customers to allow customers to make informed decisions when selecting venders to fulfill the request.
