The present invention discloses a data query system and method, and is applicable to the field of database technologies. The system comprises a time setting unit, a first indexing unit, a second indexing unit and an index combination unit. The method comprises: step S1, acquiring query time associated with an externally inputted query request; S2, searching to obtain all data stored in a data storage system at the query time, and associating the data to a preset index parent node; step S3, associating the all data stored at the query time with different index child nodes of the index parent node according to values; and step S4, integrating the index parent node and all the corresponding index child nodes to form a tree structure index used for data query performed by a user. The above technical scheme has the advantages of improving data query efficiency and shortening data query time.

The invention discloses an online multimedia interactive system and method, belonging to the technical field of multimedia interaction. When the current execution node is executed, a streaming media server generates streaming media data and pushes the streaming media data to each client in real time; each client acquires the related information including the key information input by the user in real time and sends the related information to a data processing server; the data processing server acquires the related information input by all the clients in real time and performs statistics on all the related information according to the key information to obtain the statistic result; according to the statistical result, the data processing server generates a conditional selection instruction according to the instruction generation strategy and sends the conditional selection instruction to the streaming media server; and the streaming media server generates a determined judgment result according to the condition selection instruction and the judgment condition and then executes the next execution node. The online multimedia interactive system and method improve the multimedia interactive user experience and reduce the client's configuration requirements.

The invention discloses a digital gas density relay with a self-diagnosis function and a self-diagnosis method of the relay. The digital gas density relay comprises a gas density detection sensor, anintelligent control unit, an annunciator, a communication module, a normally open electric control valve and a normally closed electric control valve; one end of the normally open electric control valve is provided with an interface communicated with electrical equipment, the other end of the normally open electric control valve is communicated with one end of the normally closed electric controlvalve, the other end of the normally closed electric control valve is communicated with air, and the gas density detection sensor is arranged on a gas path between the normally open electric control valve and the normally closed electric control valve; the intelligent control unit is connected with the gas density detection sensor, the annunciator, the communication module, the normally open electric control valve and the normally closed electric control valve to complete on-line monitoring of the gas density value of the electrical equipment and control the annunciator to control switching ofthe on-off states of the normally-open electric control valve and the normally-closed electric control valve. The gas density of the gas-insulated or arc-extinguished electrical equipment is monitored, meanwhile, online self-inspection or self-diagnosis is completed, maintenance is not needed, the operation and maintenance cost is reduced, and safe operation of a power grid is guaranteed.

The invention relates to an air conditioner with a function of self power generation. A temperature difference power generation square matrix is arranged at a place with the highest temperature between a compressor and a reversing valve and behind a condenser, and radiates heat under the action of an outer fan to form temperature difference between the hot inside and the cold outside so as to carry out temperature difference power generation. An outer fan power generator is arranged in the front of the outer fan and generates power by utilizing wind power of the outer fan. An inner fan power generator is arranged in front of an inner fan at the inner side of an evaporator and generates power by utilizing the wind power of the inner fan. A flow limiter with a function of power generation replaces a flow capturing system in the conventional air conditioner and refrigerating unit and generates power by utilizing the fluid effect of a refrigerant. On the premise of no influence on heating and cooling functions of an original air conditioner, the traditional air conditioner for heating and refrigerating is changed to be a comprehensive heating, refrigerating and power generation all-in-one machine, and the generated power generated is supplied for powering the air conditioner by a control system. The air conditioner with the function of self power generation, disclosed by the invention, has the advantages of large power generation amount, simple structure, energy saving, environment friendliness, low cost and easiness in popularization.

The invention provides a maintenance-free gas density relay, which comprises a gas density relay body and a first gas density detection sensor which are communicated on a gas path, and an intelligentcontrol unit connected with the gas density relay body and the first gas density detection sensor respectively, wherein the intelligent control unit compares and verifies a first pressure value and asecond pressure value acquired under the same gas pressure, and / or compares and verifies a first temperature value and a second temperature value acquired under the same gas temperature, or compares and verifies a first density value and a second density value acquired under the same gas density, the intelligent control unit can also upload the received data to a background, and the background carries out data comparison. According to the invention, the gas density relay is used for monitoring the gas density of gas-insulated or arc-extinguished electrical equipment and completing online self-checking or mutual checking of the gas density relay at the same time, improves the efficiency, is free of maintenance, reduces the cost, and ensures the safe operation of a power grid.
