The invention discloses a system for multi-entrance admission registration of exhibition audiences. The system comprises a plurality of mobile electronic devices arranged at each entrance and used for inputting audience admission information, an electronic registration system server, a wireless router used for building a local area network, and a switch or a concentrator. The electronic devices comprise a PC (Personal Computer), a smart phone or a tablet personal computer; an electronic registration system client is installed on the PC, the smart phone or the tablet personal computer, and the electronic registration system client is set to communicate with the electronic registration system server through a local area network; and the electronic registration system server is configured to receive and check the audience entrance information transmitted by the electronic registration system client, return confirmation information to the electronic registration system client if confirming that the audience entrance information can be acknowledged, and generate a two-dimensional code picture from the audience entrance information according to a two-dimensional code protocol.

The invention discloses a method and device for establishing a path. The method comprises the steps that a path computation element obtains colorful light port parameters of client layer devices at two ends; a first optical path between two boundary nodes is established in an optical transport network domain according to parameter information of an optical transport network and an optical wavelength range supported by the client layer devices at the two ends; optical path parameters are obtained, and whether the optical path parameters satisfy a constraint condition of a black link of the optical transport network or not is determined; the first optical path is deleted if the constraint condition is not satisfied, and a second optical path is established until the optical path of which optical path parameters satisfy the constraint condition is established; whether parameters of black link ports of the client layer devices at the two ends satisfy a constraint condition range or not isjudged after the optical path of which optical path parameters satisfy the constraint condition is established; and the end-to-end optical path is determined for the client layer devices at the two ends if the constraint condition range is satisfied.

The invention provides a method and device for importing data into a gallery based on rocksdb and a storage medium, and the method comprises the steps: classifying the data to be imported into the gallery to obtain a plurality of data categories, setting a category identifier for each data category, and setting an edge relation between the data in each data category; based on a rocksdb vertex duplicate removal database, performing duplicate removal on data in each data category, and inserting the data into the image library as a vertex; and based on the rocksdb edge duplicate removal database,performing duplicate removal on the edge relationship among the data, and inserting the edge relationship into the image library as an edge. According to the method, firstly, a rocksdb vertex duplicate removal database and a rocksdb edge duplicate removal database which correspond to data types are constructed; the method comprises the following steps of: importing data into a gallery; accordingto the technical scheme, the vertex importing is firstly carried out, and then the vertex importing is carried out after the vertex importing is completed, so that the problem that the actual data isrepeated and unavailable due to the fact that id is not duplicated when the Titan/Janus Graph image library is imported is solved, and due to the fact that the duplicate removal library of multiple types is established, the duplicate removal efficiency is improved, and the user experience is improved.

The invention discloses a balance calibration method and a system based on a cloud SIM. The method comprises the following steps: issuing a balance calibration instruction of a first SIM card consisting of balance calibration request information and balance calibration certificate information; obtaining balance information of the first SIM card according to the balance calibration instruction of the first SIM card; the technical problems that in the prior art, due to the fact that the balance of the SIM card in the cloud SIM application system is inconsistent with the balance calculated by theoperator to which the SIM card belongs, the SIM card allocated to the terminal user by the cloud SIM application system is not available, and the user experience is poor are solved.

The invention discloses a passive ventilation device which comprises a compressed air storage tank used for storing compressed air; the vortex tube is connected with the compressed air storage tank, the vortex tube is used for generating vortexes by the compressed air to separate cold airflow and hot airflow, and the vortex tube comprises a vortex tube body, a vortex tube hot end and a vortex tube cold end, and the vortex tube hot end and the vortex tube cold end are arranged on the vortex tube body; the purification mechanism is connected with the hot end of the vortex tube, and the purification mechanism is used for purifying air in the resident area through the hot airflow separated from the hot end of the vortex tube and then sending the purified air into the resident area; and the ventilation mechanism is connected with the cold end of the vortex tube, and the ventilation mechanism is used for feeding the cold air flow separated from the cold end of the vortex tube into the resident area, providing fresh air and cooling for the resident area and maintaining the positive pressure of the area. According to the ventilation device, compressed air is separated into cold air flow and hot air flow through the vortex tube, and power is provided for the ventilation mechanism and the purification mechanism through the pressure of the compressed air.

The invention discloses a cross power supply structure of nuclear power station control room man-machine interface equipment. The cross power supply structure comprises a first column power supply structure, a second column power supply structure and a third column power supply structure, wherein each column of power supply structure comprises a first power supply and a second power supply, the first power supply and the second power supply are connected to a bus of a power supply cabinet corresponding to the column through a switching circuit, and the output end of the power supply cabinet isconnected to the man-machine interface equipment corresponding to the column; and at least one power supply of each column of power supply structure is also connected to buses of other columns of power supply cabinets so as to realize cross power supply among different columns of power supply structures. Compared with the prior art, the power supply problem of multiple columns of equipment can beeffectively solved, the reliability and safety of control room man-machine interface equipment are improved, the human factor failure probability of control room operation personnel is reduced, and the operation safety of a nuclear power station is improved.
