The invention discloses a data acquisition method for acquiring system data based on the industrial Internet of Things. The method comprises the steps: obtaining the data, needing to be acquired by the system, of a plurality of industrial devices, and at least dividing the plurality of industrial devices into a first type of devices, a second type of devices and a third type of devices according to the purposes of the plurality of industrial devices, collecting, by a plurality of node gateways, data of a plurality of industrial devices of the system and uploading the collected data of the plurality of industrial devices to a platform layer through a base station gateway, and if the platform layer does not receive data of the first type of devices from the base station gateway within a preset time, uploading, by the base station gateway, the data of the first type of devices to the platform layer through a first communication path. According to the data acquisition method disclosed by the invention, the data of a plurality of devices in the system can be acquired, and the data of important devices in the system can be timely and continuously acquired.

The invention discloses a method for acquiring surrounding road conditions by a mobile terminal, which relates to the method for acquiring information from a service center by the mobile terminal. The method comprises that: the service center records mapping relationships between road sections in an electronic road condition map and the road sections in a standard electronic map into a road condition table; the service center periodically updates the road conditions in the road condition table; the mobile terminal generates a road condition request comprising current position coordinates and a searching radius, and transmits the road condition request to the service center; the service center finds all the road sections meeting conditions and numbers thereof from the standard electronic map according to the road condition request, further extracts road condition states of all corresponding road sections from the road condition table, and finds congested and crowded road sections from all the corresponding road sections; the service center generates textual description information comprising the names, congestion or crowding of the road sections for the congested and crowded road sections; the service center returns the textual description information to the mobile terminal; and the mobile terminal displays the textual description information. In the method, high processing speed and small data traffic are ensured, and the mobile terminal is free from the influence of electronic road condition map sorts.

The invention discloses an intelligent household privacy protection method based on full homomorphic encryption, comprising that: a user APP negotiates with an intelligent household gateway about the full homomorphic encryption public-private key pair; the intelligent household gateway performs the full homomorphic encryption on the collected data by using the public key and transmits the data to a server of an intelligent household network service provider to perform storage and related addition-multiplication calculation based on the ciphertext; the user APP makes a request to the intelligent household server to obtain a specific ciphertext addition-multiplication calculation result; when the ciphertext addition-multiplication calculation result is transmitted to the user APP, the user APP utilizes the corresponding full homomorphic encryption private key to perform deciphering to obtain the corresponding ciphertext addition-multiplication calculation result. On one hand, the invention dramatically reduces the calculation amount on the intelligent terminal where the user APP is positioned and saves the energy consumption, and, on the other hand, the invention saves the data transmission flow between the user APP and the intelligent household server.

The present invention relates to a business information-oriented multi-enterprise and multi-user shake-and-shake switching presentation and interaction method, comprising: a user logs in at a mobile terminal client, and initiates a business information query including user identification information and / or user client terminal identification information Request; the cloud service capability platform obtains the query request, queries the relevant business information from various enterprises that currently meet the conditions, and retrieves the corresponding pre-stored display mode according to the user identification information and / or user client terminal identification information. According to the corresponding pre-stored display mode, the different pages or sub-labels sort out the business information list and return it to the user client for display according to the pre-stored corresponding display mode. The invention allows users to request to view the business information of multiple associated enterprises at one time, and displays them according to user requirements, which facilitates unified management and query of information, and enterprises can share user resources to a certain extent, and conveniently expand their publicity, service, and precise marketing breadth.
