65 results about "Mating system" patented technology

A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances. Recognised systems include monogamy, polygamy (which includes polygyny, polyandry, and polygynandry), and promiscuity, all of which lead to different mate choice outcomes and thus these systems affect how sexual selection works in the species which practice them. In plants, the term refers to the degree and circumstances of outcrossing. In human sociobiology, the terms have been extended to encompass the formation of relationships such as marriage.

Multifunctional lift type suspension rail transportation system and braking, lifting, stabilizing and turnout device thereof

The invention discloses a multifunctional lift type suspension rail transportation system which is composed of overhead struts, truss tubular girders, a rail, a steering frame, a lifting and stabilizing system, a vehicle, turnouts, station facilities and automatic control and other mating systems, wherein the design of the multifunctional truss tubular girders can selectively realize functions of water pipes, pedestrian passageways, greenery landscapes, solar power generation and common pipelines on the basis of lightening dead-weight and saving materials to the maximum extent. The vehicle runs under the steering frame in a suspending mode, and the steering frame is composed of a phi-shaped plate rail, a U-shaped steering bracket with an upward opening and a permanent magnet brake device. As a magnetic suction caterpillar instead of a traveling wheel pair is used for driving a brake device, climbing ability can be improved greatly. A monolithic movement turnout is used for steering. When an overhead station is not selected, a lifting system and a self-compression foldable frame type anti-shaking and anti-falling device are selected, so that big marshalling operation and seamless linkage of multiple modes of transportation can be realized. The multifunctional lift type suspension rail transportation system is applicable for the field of urban or inter-city rail transportation, and has multiple technical specifications from low traffic volume to high traffic volume.

Pre-warning method and system for mud-rock flow

The invention discloses a pre-warning method and a pre-warning system for mud-rock flow of a river basin, which are implemented by presetting a warning rainfall value. Aiming at the technical problems of unavailable correct definition of a critical rainfall value serving as a preset warning rainfall value, high data requirement on the application of a critical rainfall calculation method and the like, the invention discloses a pre-warning method and a pre-warning system for the mud-rock flow of the river basin, which take a characteristic rainfall value as a river basin mud-rock flow warning rainfall value. A relevant long-term daily rainfall observed data sequence of a specified mud-rock flow river basin is selected as a basis and a certain rainfall characteristic value which is in the daily rainfall data sequence and directly and firmly related to the occurrence of the mud-rock flow is determined to be used as the warning rainfall value of the river basin for the pre-warning method and the pre-warning system for the mud-rock flow by calculating and analyzing. The method has the advantages of reliable principle, easily-acquired basic data, simple calculation index, scientific, simple and convenient calculation process, simple equipment of a mating system and low construction cost. Tests show that the method and the system have high prediction accuracy for the occurrence of the mud-rock flow of the river basin.

50Hz and 100Hz protection and setting method for high voltage DC power input system

The invention relates to a 50Hz and 100Hz protection setting method for a high voltage direct current transmission system. The 50Hz protection setting method includes the following processes: 1) The 50Hz protection input or 100Hz protection input is filtered by a low-pass filter (1) to obtain the 50Hz component or 100Hz protection input; 2) The above 50Hz component or 100Hz protection input and Comparing the fixed value in the comparator (2), in the 50Hz protection setting method, if it is greater than the fixed value, after the delay time T1 starts the current reduction section, the delay time T1 is coordinated with the switching time of the pole control and valve control redundancy; the arrival delay Time T2 starts the DC blocking sequence, and the delay time T2 cooperates with the overstress capability of the converter valve and cooperates with the protection of other converter valves. In the 100Hz protection setting method, the above-mentioned 100Hz component is compared with the fixed value in the comparator (2). If it is greater than the fixed value, the DC blocking sequence is started after a delay T. The components with the greatest stress are matched with the corresponding setting values ​​of the AC system. The invention not only realizes backup protection for converter valve faults and AC system faults, but also avoids system instability problems caused by simultaneous power reduction or blocking of multiple DC circuits in the AC-DC hybrid power grid under the premise of ensuring the safety of the main equipment.
