The invention discloses a full-text retrieval matching method and system based on a Lucence custom lexicon, and relates to the field of big data search. The method comprises the following steps: in a Lucence search environment, obtaining a search word input by a user in real time, detecting whether a result is searched or not, removing special characters from the search word if no results are searched, and storing into the Lucence custom lexicon; if the result is searched, carrying out word segmentation on the search word, continuously searching a plurality of phrases subjected to the word segmentation, detecting whether the result is searched or not, removing the special characters from the phrases, which can not search the result, subjected to the word segmentation if no results are searched, and storing into the Lucence custom lexicon; if the result is search, recording search time, the search word subjected to the word segmentation and search feedback information, and finally establishing the Lucence custom lexicon which supports Lucence full-text retrieval. According to the search word input by the user, the method can quickly and effectively establish an own customized Lucence custom lexicon.

The invention provides a method for establishing the inter-satellite links of a Beidou navigation system. The method is used for solving the problem in the prior art that the communication cannot be realized due to the fact that a satellite body in a link-establishing planning chart for the preset inter-satellite links of a Beidou navigation system in China breaks down. According to the technical scheme of the invention, firstly, a logical address is set for each satellite in the system. After that, the fault state information of a satellite is added into the information of the Beidou navigation system. In this way, the fault occurring moment of the satellite body can be shown. Based on the fault information delivery policy, all satellites in the system can acquire the state information of a faulty satellite. Meanwhile, the fault state information of the satellite is written into a temporary chart through updating the temporary chart of the link-establishing planning chart. Finally, the updated temporary chart and a node satellite chart are read, so that the new links of the Beidou navigation system are established. The establishing accuracy and the establishing timeliness of the inter-satellite links of the Beidou navigation system are improved.

The present application discloses a smart heat network data transmission security protection system and method. The system includes a transmission encryption system on the thermal user side and a transmission encryption system server side on the power plant side. The transmission encryption system is integrated into the thermal system in the form of a national secret security SDK User totalizer; the server side of the transmission encryption system is deployed at the data entrance and exit of the smart heating network management system server on the power plant side; the transmission encryption system establishes a key management mechanism to establish a secure data transmission between the heat user side and the power plant side The power plant side transmission encryption system server side acts as the reverse proxy server of the smart heat network management system, and at the same time authenticates the encrypted connection, encrypts the data, decrypts it and unloads it, and realizes the security protection of the data transmission of the smart heat network. The invention guarantees the integrity and confidentiality of the heat network data, strengthens the data processing capability, and improves the flexibility and usability of the system.

The invention discloses a distributed file transmission method, a server and private cloud equipment. The method comprises: receiving, by a public server located on a public network, a file acquisition request from a first client; obtaining available transmission nodes in a group virtual space of the public server; and pushing the available transmission node information and the file information of the file to the first transmission node, so that a transfer transmission channel is established between the first transmission node and at least one of the available transmission nodes, the file stored in the available transmission node or a part of the file is transmitted to the first transmission node through the transfer transmission channel, and downloading by the first client is facilitated. In this way, the efficiency and reliability of obtaining the file can be improved.

The invention discloses an automatic modeling method for data of data sources. The method comprises following steps: accessing multiple data sources and analyzing table structures; accessing data of different data sources and analyzing table structures of all tables of all data sources; identifying business objects of table structures in the data sources; traversing all the tables of the data sources, extracting attribute lists needed modeling, setting attributes in all the attribute lists with names for business objects, types for business objects and clustering modes for business objects; merging business objects in similar terms; summarizing attributes set with business objects and clustering similar terms; analyzing business objects and modeling in order to generate a modeling structure set; and modeling attributes set with business objects according to setting parameters and modeling attributes not set with business objects according to a modeling rule. The modeling rule comprises: numeric attributes marked as metric; non-numeric attributes marked as dimensionality; and business objects in similar terms are merged. Data modeling operation can be conveniently performed, which is beneficial for analyses of mass data of users.

The invention discloses a method for establishing an urban landscape water body ecological system. The method comprises the following steps: improving a water body substrate; planting submerged plants by using a method that upright posts are adopted to mark areas, so as to establish an underwater frost; planting layered emergent aquatic plants; putting zooplankton (daphnia magna) so as to improve the transparency of the water body; putting aquatic organisms such as fishes, shrimps and shells, so as to complete the water body ecological system; maintaining and managing the ecological system. Through the adoption of the method, the quality of the water body can be remarkably improved, the transparency can be greater than 2.0m, the quality can meet the III-type water quality standard for a long time, black, smell and dirty water bodies with blue-green algae can be thoroughly eliminated, and the water body is always kept clear completely.
