A method includes the energy acquisition step, the electric energy management step and the load power supply step. In the energy acquisition step, various modes of energy besides heat energy, solar energy, vibration energy, tire deformation and the like on a vehicle is acquired and converted into electric energy, the electric energy is continuously supplied to vehicle information monitoring loads, and therefore self power supply of a vehicle information monitoring system is achieved. Different types of energy acquisition devices are adopted according to the different energy modes supplied by the environments where the different loads are located. In the electric energy management step, the electric energy acquired by the energy acquisition devices is managed according to the output characteristics of the energy acquisition devices and the power use characteristics of the loads, so that the optimal electric energy use efficiency is obtained. The vehicle information monitoring self power supply system can be applied to real-time detection of the vehicle speed and the loads, automatic adjustment of the safe air pressure range of tire pressure monitoring equipment and auxiliary safe driving for tire puncturing prevention and tire puncturing accident prevention.

The invention discloses a method to prevent high voltage wall bushing flashover under non-uniform rain and corresponding device that can effectively prevent high voltage wall bushing flashover under non-uniform rain. The method is simple in installation and has lower cost, but can effectively settle the problem of bushing flashover under non-uniform rain. The method adopts the basic principle that a uniform rain device that can avoid non-uniform rain moistening is arranged directly above the top of the bushing in order to ensure uniform moistening on the surface of the bushing. When the surface of the bushing is uniformly moistened, the electric field distribution on the surface is almost consistent with which when the surface of the bushing is completely dry, so the flashover problem caused by non-uniform electric field distribution when the surface of the bushing is non-uniformly moistened can be effectively settled. The device consists of a uniform rain net and a uniform rain net support. The side length of each mesh of the uniform rain net shall not be less than 30mm, and the water drop on the surface of the net in the state of slanting raining shall be ensured to drop vertically on the surface of the bushing. The net adopts stainless steel or high strength insulation material. The mounting height of the net shall be detailedly calculated, and relevant experiments shall be carried out when necessary to ensure the minimum distance between the net, the support and the bushing end meet the requirement of safe air distance and avoid electric power generation. When the installation is completed, experiment with the net using artificial rainfall shall be conducted to ensure that the surface of the bushing can be uniformly moistened. The operating principle of the uniform moistening on the bushing shall refer to an attached drawing in the abstract.

The invention discloses an embedding riveting bracket for connecting an automobile interior instrument board with a safe air bag cabin and a method for connecting the embedding riveting bracket with the interior instrument board. A technical scheme is that: a plurality of perforations for connection are formed on the embedding riveting bracket; counter bores for forming snaps during injection moulding are formed on a mould core of an injection mould of the interior instrument board opposite to the perforations; and the embedding riveting bracket serving as an insert is embedded in the injection mould of the interior instrument board, so that the embedding riveting bracket is connected with the interior instrument board into a whole in an embedding riveting way along with the injection moulding of the interior instrument board. The embedding riveting bracket solves the problems of undetermined reliability, difficult detection and high manufacturing cost in the prior art. The embedding riveting bracket for connecting the automobile interior instrument board with the safe air bag cabin provided by the invention enables the connection of the bracket and the interior instrument board to get rid of the disadvantage of ultrasonic welding through an injection moulding embedding riveting connection mode and fulfils the aims of connecting reliably, detecting easily and reducing cost.
